Special cutting machine of convex tooth on hollow cylinder

Abstract

The invention discloses a special cutting machine of a convex tooth on a hollow cylinder. A welding gun translation device is designed at the upper end of a bracket of the special cutting machine, and a workpiece fixing device and a workpiece circumferential rotating device are designed in the middle of the bracket. When an operator adopts the special cutting machine to cut, the hollow cylinder is arranged on clamping heads, a rotating wheel at the rear end of a jacking screw rod is rotated, a jacking head at the front end of the jacking screw rod is enabled to push the clamping heads, and then the clamping heads are opened to clamp the cylinder from the inner circle of the hollow cylinder; a rotating handle and a welding gun translation rotating disc on a rotating sleeve are rotated, the position of the welding gun is adjusted, the head of the welding gun is just aligned to a designed cutting seam, the welding gun is started to cut, the welding gun translation rotating disc is rotated to enable the welding gun to cut in the axial direction, and the rotating handle on a rotating sleeve is rotated to enable the welding gun to cut in the circumferential direction, so that convex teeth can be cut in the cylindrical surface of the hollow cylinder. The special cutting machine is simple to design, relatively low in manufacturing cost and convenient for operators to align the cutting points, the positions of the cutting points of the welding gun in the cutting process are stable, and the precision of a cut workpiece is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of welding fixtures, and relates to a special cutting machine for convex teeth on a hollow cylinder. Background technique [0002] In the cutting work of cutting the axial convex teeth on the cylindrical surface of the hollow cylinder with a welding torch, due to the lack of a special cutting machine, the cutting work is completed by the welder manually operating the welding torch. Not only the precision of the cut workpiece is poor, but the operator's work The intensity is also great. Contents of the invention [0003] In order to improve the cutting accuracy of cutting axial convex teeth on the cylindrical surface of the hollow cylinder and reduce the work intensity of the operator, the invention provides a special cutting machine for convex teeth on the hollow cylinder. The upper end of the bracket of the machine is designed with a middle part The fork frame with holes is installed on one side of the u...
