A jig and tool are provided for rotating the tool around a pipe or pipeline, for truing the pipe end. An operator can easily installation the jig into the pipe end, with or without the cutting tool installed thereto. The tool can be manually or motor driven for rotation about the jig and the pipe end. The attachment of the tool to the jig enables alignment of the tool's cutting face with the pipe end, with angular and axial adjustment available for obtaining a profile suitable for welding to like pipe ends. In an embodiment, the tool can track the pipe diameter to retain alignment despite out-of-round dimensional variation. The tool is operated and rotated about the pipe end to remove material and, as necessary, the tool is adjusted into the pipe end and the rotation about the pipe end is repeated for incremental removal of material therefrom.

The present invention generally relates to assembly equipment of valve body, especially to riveting and grinding assembly for nozzle of screw shaft valve. The invention may include a rack, a power control box, a turntable and a turntable divider. A carrier assembly which engages with the screw shaft valve body is installed on the edge of the turntable with uniform distribution. On the center part of the turntable, a support shaft which is installed on and fixed with the rack is vertically interposed and on the top of the support shaft, an upper supporting disc is installed. A valve pipe feeding device, a valve pipe preloading device, a valve pipe riveting device and a valve pipe grinding device which engage with the carrier assembly are installed on the said rack on the rotational direction of turntable. As the threaded pipe is put into the carrier assembly by valve pipe feeding device, the carrier assembly rotates counterclockwise along the turntable and rotates to the valve pipe feeding device to the press threaded pipe into the valve seat. Thereafter the carrier assembly rotates the valve pipe riveting device and rivets threaded pipe with a valve flange in order to finish assembling process. Finally, the carrier assembly rotates the valve pipe grinding device to grind nozzle of valve to finish grinding and riveting process of threaded pipe with high positioning accuracy of assembly and marvelous hermetic sealing.

A method measures an edge of a workpiece by scanning. The scanning is performed by a scanning tool mounted on a moving head of an edge-facing machine while that moving head is moved along the edge to be measured before, during or after an edge facing tool of the edge-facing machine that faces the edge. The method can be performed by an edge-facing machine that includes at least one edge facing tool and that further includes a scanning tool mounted on a movable head of the machine, which head is movable along an edge of a workpiece.

An apparatus for surface finishing a flange surface of a flange of a pipe includes a frame assembly, a drive assembly coupled to the frame assembly, and a bracket assembly coupled to the frame assembly. The flange is clamped between the frame assembly and the drive assembly. The drive assembly circumferentially translates the apparatus around the pipe. A power tool is coupled to the bracket assembly to perform the surface finishing operation on the flange surface of the flange.

An endoscope having a pipe connection structure includes a pipe of a corrosion-resistant alloy material and a piping block of a corrosion-resistant alloy material, the piping block having a pipe insertion hole. An end of the pipe is fitted in the pipe insertion hole, the pipe and the piping block are connected by welding by irradiating a laser beam on the entire circumference of an area where the end of the pipe is fitted in the pipe insertion hole in the piping block, and an axial length of the pipe inserted in the pipe insertion hole is in a range of 0.5 to 2 times a wall thickness of the pipe.

The Deburr-It Bit is a versatile tool bit designed to be used manually with smaller size circular hollow ridged tubing or with a motorized drill during the installation of all types and sizes of circular hollow ridged tubing. The function of the Deburr-It Bit is to remove burr that is formed on said tubing when the tubing is cut with various types of saws and cutting tools. In most cases, the removal of burr allows the circular hollow ridged tubing to easily slip into the manufactured fitting orifice found on all fittings which could include elbows, valves, couplings, adaptors, and most types of connectors. It should also be noted here, that removal of burr, on the inside edge of circular hollow ridged tubing, is necessary to have a smooth unrestricted surface for the best fluid flow possible. The purpose of this Deburr-It Bit is to completely remove burr from the inside edge of said tubing, the outside edge of said tubing, and release burr waste debris particles to the atmosphere at the same time during said bit rotation. What is unique is the beveled circular double-wall V-shaped abrasion cavity surfaces of the Deburr-It Bit, that when in contact with said tubing, will remove the burr from both the inside edge of circular hollow ridged tubing and outside edge of circular hollow ridged tubing at the same time and in a shorter amount of time, resulting in two smooth unrestricted tubing surfaces. There is no need for expensive machinery.

A multifunctional device for removing a film from a pipe is disclosed. The multifunctional device for removing a film from a pipe, according to the present invention, is a device for removing a film from the inner surface or outer surface of a pipe, and comprises: a tool part for removing the film; a roller part including at least one surface roller traveling on the inner surface or outer surface of the pipe; and a connection part including a first plate connected to the tool part, and a second plate which is arranged on the other side of the first plate so as to be connected to the first plate through one shaft and which is connected to the roller part.

A machining device for machining the lateral surface of an approximately cylindrical object in portions thereof includes a chain for annularly surrounding the object to be machined. The chain consists of at least two hingedly connectable chain links, one of which is a tool holder having at least one tool for machining the lateral surface. The device also includes support rollers for rolling on the lateral surface. The at least one other chain link is a chain connecting link. The chain links are connectable in such a way that they form a closed chain ring around the object to be machined. The machining device further includes a feed adjuster capable of reversibly adjusting an axial position of facing ends of two chain links parallel to the axis of the closed chain ring relative to each other.

A pipe beveling tool has an arcuate pipe adapter mechanically attached to a wedge member, which is itself mechanically attached to a connecting bracket which is itself mechanically fastened to a disc cover member in such a way that both the disc cover member, and the connecting bracket clamp onto a grinding tool section proximal a grinding disc by way of tightening thereonto. The pipe adapter has a pair of flaps hingedly attached to a fixed adapter member so as to adapt to various pipe diameters.

A scraper tool for deburring an edge of an aircraft turboshaft engine casing is arranged to be mounted in a milling device. The scraper tool includes a body including, on a first end, a connection for the milling device and, on a second end, a deburring module including a turning lathe platelet including at least one cutting edge arranged so as to deburr the casing edge. The deburring module includes a guide adapted to contact the edge to be deburred so as to follow the profile of the edge to be deburred without modifying the orientation of the turning lathe platelet.
