Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and in particular relates to an automotive parts positioning and clamping device. Background Technology

[0002] Chinese Patent ZL202421370156.4 relates to a positioning fixture for automotive parts. The fixture includes a base with fixed seats fixedly connected to both ends. A fixed rod is fixedly connected between the fixed seats. Two sets of symmetrically arranged sliding seats are slidably connected to the fixed rod. A telescopic drive assembly for driving the two sets of sliding seats to move in opposite directions is connected to the sliding seats. One end of a rotating rod is rotatably connected to the sliding seat, and the other end of the rotating rod is fixedly connected to a rotating platform. This fixture synchronously installs and fixes multiple sets of different types of clamping heads through a rotatable mounting column. The clamping heads can be synchronously rotated and replaced by rotating the mounting column synchronously to accommodate the clamping and fixing of different types of parts. Then, the parts are clamped and fixed by the opposite movement of the two sets of clamping heads, improving the practicality and processing accuracy of the equipment.

[0003] While the above technical solution achieves synchronous replacement of the clamping heads of the positioning fixture, the following risks exist because the two rotating tables operate synchronously through gear meshing: 1) The positioning fixture is used to clamp the automotive parts to be processed, and debris from the automotive parts during processing can easily enter between the gears, causing damage to the gears; 2) The gaps at the connection points of transmission components, including gears, connecting shafts, and rotating connecting arms, are small and difficult to clean; 3) When the positioning fixture clamps the automotive parts, the clamping heads exert stress on the parts to ensure they are firmly fixed. At the same time, the automotive parts also exert opposite stress on the clamping heads. This stress acts on the clamping heads and also on the transmission components such as rotating rods and gears, which may cause damage to the transmission components such as rotating rods and gears over time.
