As a preferred scheme of the utility model, the butterfly plate connecting hole comprises a butterfly plate positioning pin hole and a connecting round hole; the clamping fixture connecting hole comprises a clamping fixture positioning pin hole and an opening long hole arranged at the edge of the mounting plate; the clamping fixture positioning pin hole corresponds to the butterfly plate positioning pin hole, and the opening long hole corresponds to the connecting round hole.
The utility model has the beneficial effects that:
after the tire body and the butterfly plate body are matched, the tire body is connected with the chuck of the sleeping car, and the sleeping car can be used for processing the butterfly plate at one time only by calculating the included angle alpha between the positioning protrusion and the chuck according to the angle requirement of the butterfly plate, so that the efficiency is high, a large amount of working hours can be saved, the processing precision is not limited by the level of an operator, and the product consistency is good.
The positioning bulge and the positioning sleeve structure have strong universality, can be applied to the production of butterfly plates with different specifications and the same angle, and greatly saves the cost of processing equipment.
The butterfly plate positioning pin hole and the clamping fixture positioning pin hole can realize accurate positioning of the butterfly plate and the clamping fixture, and then are connected and fixed by the connecting round hole and the opening long hole, and the opening long hole has good adjustability, so that the universality of the butterfly plate positioning pin hole and the clamping fixture positioning pin hole is further improved.
