Coupler jaw welding clamp

Abstract

The invention discloses a coupler jaw welding clamp. The coupler jaw welding clamp comprises two guide wheels which are symmetrically arranged and capable of rotating around respective axes, wherein a compressor is arranged above the symmetrical center line of the two guide wheels; the compressor comprises a casing, and a lifting column arranged inside the casing, a handle capable of driving the lifting column to go up and down is arranged at the upper end of the lifting column, the lower end of the lifting column is hinged with a compressing wheel mounting seat with a mounting plate, a pair of compressing wheels symmetrically arranged are placed on the mounting plate of the compressing wheel mounting seat, two connecting plates are arranged on the two sides of the casing, and the bottom ends of the two connecting plates are respectively connected to fixed supporting seats. After the adoption of the structure, when a workpiece is required to be welded, the workpiece can be compressed and fixed by using the compressor, meanwhile, due to the arrangement of a structure capable of opening and closing between the connecting plate and the supporting plate, workpiece clamping and fixing can be convenient. Therefore, the stability of the workpiece under a welding state can be ensured, the welding quality is effectively ensured and the practicability is excellent.

Description

[0001] technical field [0002] The invention relates to a welding jig for mechanical parts, in particular to a welding jig for a coupling fork. Background technique [0003] Traditionally, in the process of welding the yoke of the universal coupling and the spline sleeve or the connecting pipe, the workpiece to be welded is generally placed on two fixed guide wheels, and then the guide wheels are rotated to weld the workpiece. This kind of welding structure, because it only relies on two guide wheels and has no other auxiliary parts, the workpiece is not pressed, so the stability of the workpiece is poor, resulting in fluctuations in welding conditions and reducing the welding quality. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a coupling yoke welding jig which can effectively guarantee the welding quality. [0005] In order to solve the above technical problems, the coupling yoke welding jig of th...

[0003] Traditionally, in the process of welding the yoke of the universal coupling and the spline sleeve or the connecting pipe, the workpiece to be welded is generally placed on two fixed guide wheels, and then the guide wheels are rotated to weld the workpiece. This kind of welding structure, because it only relies on two guide wheels and has no other auxiliary parts, the workpiece is not pressed tightly, so the stability of the workpiece is poor, resulting in fluctuations in welding conditions and reducing the welding quality
