Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a small welding positioner. Background Art

[0002] A small welding positioner is an auxiliary device used in welding operations. It is mainly used in automated or semi-automated welding processes to improve welding quality and efficiency. This device changes the position and angle of the weldment, allowing welders to access the welding area more easily while reducing welding deformation and stress.

[0003] During the operation of the small welding positioner, the workpiece is usually fixed to the upper end of the small welding positioner by a fixture, and then the small welding positioner drives the workpiece to rotate through the cooperation between the driving device and the gear, thereby adjusting the welding position of the workpiece;

[0004] When the existing small welding positioner is in use, although it can drive the workpiece to rotate by the cooperation between the driving device and the gear, after adjusting the welding position of the workpiece, in order to ensure the stability of the workpiece, it is usually necessary to use a hydraulic rod to drive the locking part to move, and finally lock and fix the gear. This method is more cumbersome to operate, and the hydraulic system is heavier and larger in size, which reduces the welding efficiency and also affects the portability and space utilization of the small welding positioner. For this reason, we propose a small welding positioner. Utility Model Content

The two bevel gears 78 are meshed and connected, and the screw 76 drives the fixing rod 72 to move backward through the adjustment plate 71. At this time, the adjustment rod 73 slides inside the adjustment groove and rotates relative to the adjustment groove, so that the fixing rod 72 drives the adjustment seat 74 to rotate through the adjustment rod 73. The adjustment seat 74 drives the fixing seat 4 to rotate through the mounting rod 3.
