Description

Technical Field

[0001] The utility model relates to the technical field of brake shoe processing, in particular to a product fixing device for brake shoe plug welding equipment. Background Art

[0002] The brake shoe is the friction component of the drum brake. Its main function is to expand under the force of the brake cam or push rod, press the brake drum, slow down the speed of the vehicle through friction, and thus achieve the purpose of vehicle braking.

[0003] Existing brake shoes often require plug welding during processing. This is typically done at the plug welding holes on the shoe, which are used to connect the different components of the shoe via fusion welding. This often requires a fixture to position the shoe. Existing brake shoe fixtures are mostly simple fixtures. However, after clamping and positioning, plug welding requires welding on both sides of the plug welding hole. This necessitates disassembling the brake shoe after welding on one side and then flipping it over to secure it. This is cumbersome and affects plug welding efficiency. Therefore, we propose a product fixture for brake shoe plug welding equipment. Utility Model Content

[0035] Further, mounting holes are formed at the top of the carrier plate 1 at four corners, so that the device as a whole is conveniently installed and fixed.

[0036] Further, a positioning hole 2 is formed in the outer wall of the turntable 12, so that when the brake shoe is clamped, the end of the brake shoe is inserted into the positioning hole 2, thereby improving the accuracy of positioning.
