Description

Axial flexible junction box welding fixture

Technical Field

The utility model relates to the technical field of clamping and welding of a waterproof junction box of a compressor, in particular to an axial flexible junction box welding clamp.

Background

At present, the parts of the junction box of the compressor are mostly produced by adopting a sheet blanking mode. Because the production in this way cannot avoid the situation that the junction box has large manufacturing tolerance, the existing junction box welding tool must reserve large allowance in design due to the consideration of the manufacturing tolerance and other problems. This just leads to terminal box and location frock contact not inseparable when actual production, and the location effect is poor. However, in order to meet the design requirements of the compressor, the position of the junction box can be manually adjusted by an operator to ensure the consistency of the welding position. There is no fixture for stably clamping the junction box, and the upper electrode on the junction box is directly opposite to the lower electrode under the junction box for welding. If the clamp is provided, the clamping position of the clamp is inaccurate due to the manufacturing tolerance of the junction box. Greatly influences the production efficiency and improves the requirements on the technical level of field operators.
