A portable and field-adjustable milling machine comprises: a base; a milling assembly coupled to the base and that includes a milling tool rotatable by a driver; a roller bed coupled to the base and configured to support a tubular member thereon; and a vice assembly that is coupled to the base. Each vice member of the vice assembly is configured to be moved towards the other of the pair and includes camming surfaces configured to lift the tubular member off of the roller bed in response to the vice members being moved toward one another. The vice member may have a v-shaped notch defined by a pair of angled surfaces. The vice assembly lifts the tubular member and retains it in the notch at a position that is a predetermined distance away from the roller bed.

A device for removing circumferential burrs of a wheel with high precision includes an electric cylinder, a lifting table, guide rails, an electric cylinder, a sliding block, a plurality of sensors, a rim burr cutter, a riser burr cutter, and the like. The device can simultaneously remove circumferential burrs from the flange edge, the outer rim and the riser slot edge, which eliminates the error caused by coaxial degree deviation, so that the rotating center of the cutters coincides with the circumferential center of the burrs. The device is configured to provide high-precision removal of burrs from the flange edge, and high-precision removal of burrs from the outer rim and the riser.

An automated system for manipulating a workpiece includes a machining device, a locating device configured to determine a position of a workpiece, and a positioning system operatively connected to the machining device and being configured to adjust a position of the machining device to align a centerline of the machining device with a longitudinal axis of the workpiece, based upon the determined position of the workpiece. The machining device includes a stabilizing mechanism to engage the workpiece to maintain the workpiece in the determined position, and a cutting element for performing a machining operation on the workpiece.

A machining fixture, comprising a base, an air cylinder, an air cylinder piston and connecting rod, a supporting guide sleeve, a sliding supporting seat, a thrust ball bearing holder and spherical bead, a floating platform, a first connecting screw, a compression block, a pin shaft, a push rod pin, a second connecting screw, a center positioning shaft, a third connecting screw, a guide sleeve, a supporting plate, an oil cylinder piston and connecting rod and a one-way oil cylinder. The floating centering self-clamping machining fixture is for machining flange-type, which improves positioning accuracy and machining precision. The fixture has an automatic returning floating platform, achieving the automatic alignment of the parts; after the alignment, a floating support moves down and is changed to a rigid support, improving stability; and a positioning rod continues to move down, such that a workpiece is automatically clamped by an ejector rod oscillating arm mechanism.

A machining system comprises a machine tool, a machine tool controller that controls the machine tool, an auxiliary device that assists the machine tool, and an auxiliary device controller that controls the auxiliary device. The machine tool and the auxiliary device work cooperatively for machining. The machining system comprises a signal management unit that receives a first signal and a second signal. The first signal indicates information about the machine tool as a criterion used for determining whether the machine tool and the auxiliary device are operable or inoperable. The second signal indicates information about the auxiliary device as a criterion used for determining whether the machine tool and the auxiliary device are operable or inoperable. The signal management unit outputs a third signal indicating an operable state or an inoperable state of the machine tool and the auxiliary device to the machine tool controller and the auxiliary device controller based on the first signal and the second signal.

A handle is coupled to an industrial machine tool, along with a method of operating the industrial machine tool via the handle. The handle comprises a housing, a first switch, and a second switch. The housing includes a first side, a second side, a top end, and a bottom end, the first side facing toward the industrial machine tool and the second side facing away from the industrial machine tool. The first switch actuates a float mode for the industrial machine tool, the float mode being a mode in which movement of a moveable portion of the industrial machine tool is power assisted for an operator of the industrial machine tool. The second switch actuates a machining portion, coupled to the moveable portion of the industrial machine tool, to perform a machining process on a workpiece.

I, Robert Thomas Wilson, being the inventor, have designed this Centering Fixture. This invention is described in enabling detail in the following example which may represent more than one embodiment of the present invention. The Centering Fixture is an accessory attachable to a milling machine vise, it centers similar pieces of material with dimensional variations. Machining processes often begin with cutting a number of pieces from larger stock. These cut pieces will vary due to accuracy limitations of the cutting method used. The Centering Fixture, incorporates two movable extensions that precisely move toward or away from one another at the same rate by rotating a leadscrew having a right-hand thread on one end and a left-hand thread on the other. Using this Centering Fixture material regardless of dimensional variations from one piece to the next are each individually centered aiding in accurate manufacturing. As an example, a cut piece 4.030 inches long would be set up with the 2.015-inch center position of that piece oriented as desired. If the next piece measured 4.120 inches long the Centering Fixture would automatically locate the center of that piece at the 2.060-inch position. This centering function would then repeat with all subsequent like pieces, in this example and in one embodiment. The Centering Fixture is portable allowing easy movement from one machine to the next.

An air bearing slide (20) arranged on a rotational table (11) includes a movable table (40) that has a workpiece placement surface (42a) and that floats due to pressure of compression air to be movable horizontally in any direction. A workpiece auto-centering apparatus includes: a plurality of stopper apparatuses (30) that include an abutment portion (31a) against which a workpiece W can abut to center the workpiece W, and a pressing apparatus that presses the workpiece (W) such that the workpiece (W) abuts against the abutment portion (31a) of the stopper apparatuses (30). Thus, the workpiece auto-centering apparatus and auto-centering method have a simple configuration and can perform a workpiece centering operation in short cycle time.

A fixture and a method of operating the fixture are disclosed for repositioning a workpiece disposed on the fixture to correct an offset between the centerline of the workpiece and an indexing position on the fixture. The fixture includes one or more linear actuators that linearly move vacuum grippers on their outboard ends into contact with surfaces of the workpiece. Vacuum is applied to the vacuum grippers, which enables the vacuum grippers to grip the surfaces of the workpiece. The linear actuators are driven to reposition the workpiece on the fixture to reduce the offset between the two below a threshold value. When in position, the fixture secures the workpiece in place for subsequent machining operations that may be performed on the workpiece.

Embodiments of the invention provide a device used for centering equipment having a center hole. The device includes a base; a central spindle partly coupled to the base; an upper supporting assembly partly coupled to the central spindle; and a centering device configured to act on the equipment having the center hole to perform centering operation. Using the centering device of the present disclosure to detect the deformation of equipment having a central hole, no fixtures are involved, thus saving the time for disassembling the equipment, and no need to select the fixtures to match the equipment, only to place the equipment in an appropriate way to complete the centering, thus improving the efficiency. In addition, no fixtures need preparing, which greatly reduces the costs.
