Turntable for positioning automobile structural part Technical Field The invention relates to a turntable for positioning an automobile structural part, and belongs to the technical field of automobile manufacturing. Background In the automotive industry, the accuracy of form and position tolerances of the hole sites and the external dimensions of automotive structural parts is increasingly important. If specialized measuring equipment is required to detect these dimensional tolerances, robots are typically used to perform the work-piece operations. The robot needs to guarantee the repeated positioning accuracy of the workpiece when the workpiece is carried by the clamp to enter the measuring equipment, besides the repeated positioning accuracy of the clamp and the robot, the workpiece needs to be precisely positioned once before the robot grabs the workpiece, so that the initial accuracy of the workpiece is guaranteed, and the workpiece is generally realized through a set of positioning middle rotary tables. The transfer equipment commonly used in the industry at present mainly comprises a simple tool tray, a fixed bracket, a common roller table and the like, and has the following technical defects: 1. The existing transfer equipment has no special positioning mechanism or adopts a simple limiting block for positioning, and the automobile structural part is easy to deviate and shake after being placed, so that the detection procedure needs to be recalibrated when the part is taken, the operation working hours are increased, and the detection precision is easily influenced by calibration errors. 2. The adaptability is poor, the size and shape difference of the automobile structural parts of different vehicle types and different types are large, the existing transfer equipment is of a fixed structure, the transfer requirements of workpieces of various specifications cannot be flexibly adapted, special transfer equipment is required to be customized for different workpieces, the production input cost is increased, and a large number of production sites are occupied. 3.
