Abstract
The present inventive concept discloses design providing for the mounting of a CNC cutting machine upon a sturdily framed wheeled vehicle. The vehicular cutting machine can then be transported upon its own integral structure, to practically any jobsite. This mobility is a particular advantage to the customer at the jobsite where there is a requirement for a smaller number of precision parts in a short time during a plant or facility start-up, shutdown, or power outage. The inventive concept presents a method of use of CNC cutting machines that has not been used in the metal-cutting industry, oftentimes because of harsh road environments or the sheer difficulty of designing and building a self-powered, self-equipped CNC cutting machine. The present inventive concept negates the problems previously encountered by the prior art, and makes possible a cutting machine which is transportable and immediately available for operation upon reaching a designated website.

DETAILED DESCRIPTION OF THE INVENTION
[0027] The following description includes the preferred embodiment for carrying out the inventive concept disclosed. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles of operation of the vehicular cutting machine 10. The scope of the concept is further defined by the claims accompanying this disclosure.
[0028] Customarily, a CNC cutting machine is set up on the shop floor inside a building, the building further having electrical wiring of suitable voltage and amps, and a source of compressed air, oxygen, and acetylene. A user or intended customer must physically bring the materials to be cut to the building, where the CNC cutting machine can then be set up to perform the work. The result is that efficiency is less than desirable due to the labor and time spent in transporting the raw materials in preparation for set up of the cutting job. The concept of a trolley containing a cutting mechanism and mounted onto a gantry-type structure which travels on parallel tracks is known in the metal-cutting industry. However the present inventive concept presents a unique and advantageous design, featuring immediate mobility of a cutting machine which is self-equipped, self-powered, and a construction enhancing entity in itself
[0029] The present inventive concept is a design allowing a CNC cutting machine to be mounted on a sturdily framed wheeled vehicle. Referred to as the vehicular cutting machine 10, this apparatus can then be transported upon its own structural frame, to practically any jobsite. This mobility is a particular advantage to the customer at the jobsite where there is an immediate requirement for a small number of precision parts in a short time during a plant or facility start-up, shutdown, or power outage. This type of wheeled, transportable CNC cutting machine has not been used in this industry, oftentimes because of harsh road environments. The present inventive concept negates the problems previously encountered by the prior art, and makes possible a transportable, vehicular CNC cutting machine 10.

[0032] The left gantry vertical beam 22 connects to the upper gantry 20, which in turn, allows movement of the gantry 20 longitudinally along the left linear guide rail 35(a), corresponding to the X-axis 27 of a computer-generated program. Rubber stops 40 limit horizontal travel of the guide roller bearing 30.
[0033] To ensure a stable platform for performing cutting operations, left and right front retractable stabilizers 70(a), 70(a) along with left and right rear retractable stabilizer 60(a), 60(b) may be extended onto the surface upon which the vehicular cutting machine 10 rests.
[0034] As is shown in
[0035] The gantry 20 is powered by an electric motor 133, which motor 133 is also moderated by a stepper motor gear reduction system 130 (shown in
[0036] As previously described, the trolley 115 is mounted on a gantry 20 which is supported upon two right-side guide roller bearings 30, and one left-side roller bearing 30. In this manner, the gantry is enabled longitudinal movement of the entire gantry 20 on the horizontal linear guide rails 35(a), (b) which corresponds to the Y-axis 27 of a computer 46generated cutting program. The guide roller bearings 30 allow the gantry 20 to roll atop the two linear rails 35 which run the length of the cutting area 25 of the cutting machine 10.
[0037] As shown in
[0038] The control console 45 is used to display and set operational parameters for operating the vehicular cutting mechanism 15. The control console 45 houses any type of industrial computer 46 with a processor and hard drive to include a programmable logic controller (PLC) or personal computer. The control console 45 is the location upon the vehicular cutting machine 10 from which a user/operator processes the software that controls the cutting process.
[0039] Typically, CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) type software is used to program the vehicular cutting machine's 10 operations. The user will occupy the bow floor space 197 (shown in
[0040] In different embodiments, the cutting mechanism 15 may be an oxy-fuel cutting torch 12, a plasma cutting device 13, or a laser cutting device 14. In the preferred embodiment, the frame structure for the vehicular cutting machine 10 is fabricated from 3.0 inch by 6.0 inch, by inch thick steel tubing. The steel tubing for the right and left lower beams 190, 191 is typically 20.0 inches in length. The vertical braces 200, 201 and lateral braces 195(a), (b) are joined symmetrically, from side-to-side at opposite locations to provide a rigid frame design which is built to withstand all traveling conditions, including rough road conditions. Adjustable rear retractable stabilizers 60(a), (b), front retractable stabilizers 70(a), (b), a 500-pound rated hitch 80, and right and left lift jacks 75(a), (b) are attached to the right and left lower beams 190, 191 of the frame. In the preferred embodiment, the entire vehicular cutting machine 10 rests upon a structural frame connected to 5,200 lb.-rated, tandem axles 65.

[0042] As shown in
[0043] As shown in

[0045] Referring to
[0046] In actual industrial use, an operator/driver typically tows the vehicular cutting machine 10 to the jobsite with a standard truck or other vehicle that has a trailer hitch compatible with the hitch 80 of the vehicular cutting machine 10. The operator secures the vehicular cutting machine 10 in a level and stationary position by adjusting rear retractable stabilizers 60(a), 60(b), and front retractable stabilizers 70(a), 70(b), and left and right lift jacks 75(a), 75(b). The vehicular cutting machine 10 is further equipped with a tubular level 270 (not shown) which is an aid to achieving orientation parallel to the horizon.
[0047] The operator secures the material to be cut; typically flat metal sheets, in the cutting area 25. The operator at the control console 45 sets operation parameters by interfacing the control console 45 with a laptop or desktop computer 46, so as to carry out a completely automatic cutting operation without manual processing, and providing precise and speedy cutting of the material.
[0048] A laptop or desk-mountable computer 46 uploads the appropriate CAD/CAM software for the particular job. The operator also checks for any last-minute cutting parameter changes in the job over a wireless network, integral to the control console 45. The operator, by means of the CAD/CAM software, controls the positioning of the gantry 20 and trolley 115. The gantry 20 positions the cutting mechanism 15 along the Y-axis 28 of the material to be cut in the cutting area 25. The trolley 115 then positions the cutting mechanism 15 along the X-axis 27 of the material to be cut in the cutting area 25. The X-axis 27 and Y-axis 28 motion of the cutting mechanism 15 allows precise cuts of any shape or design as set from the control console 45.
[0049]
[0050]
[0051]
[0052] The right upper beam 185(b) supports the right linear rail 35(b). Four support arms 162(b) support and attach four right-side linear guide rail mounts 160(b) to right vertical braces 200, 200(b) and consequently, to the right upper beam 185(b). The vertical gantry beams 24(a), (b) are attached to guide roller bearings 30 which make contact with the respective left and right linear guide rails 35(a), 35(b). The gantry 20 moves fore and aft, atop the left and right linear rails 35(a), 35(b), along the designated Y-axis of the cutting surface 25.
[0053] Also shown in
[0054] Compared with the conventional CNC cutting machines, the vehicular cutting machine 10 provides several new functions and advantages. The vehicular cutting machine 10 carries out the completely automatic cutting operation without manual processing. A significant feature of the vehicular cutting machine 10 is that its mobility saves manpower and set-up time. While a prior art CNC machine is going through its set-up stages, it cannot be producing required work pieces, which amounts to non-productive time which cannot be recovered. The reduction in set-up time reduces the manufacturing costs. The vehicular CNC cutting machine 10 can be towed in to a worksite and typically set-up in less than 15 minutes.
[0055] The vehicular cutting machine 10 is constructed with several different embodiments and operational features, including an operator's umbrella 260; a printer within the control console 45; an integral mobile hotspot within the control console 45 for providing a wi fi network; Windows-based CNC control software; a 13,000-watt portable generator; a retractable electric cord reel; and a gas-powered air compressor for CNC plasma cutting processes.
[0056] Many variations of this inventive concept will occur to those skilled in the art. Some variations include the vehicular CNC cutting machine dimensions; and the type of cutting mechanism. All such variations are intended to be within the scope and spirit of the inventive concept. Although some embodiments are shown to include certain features, the applicant specifically contemplates that any feature disclosed herein may be used together or in combination with any other feature on any embodiment of the invention. It is also contemplated that any feature may be specifically excluded from any embodiment of an invention.
