The technical scheme of the utility model is as follows: a vehicle clamp for processing an inner hole of a special-shaped part comprises a clamp body, a compression assembly, a small cylindrical end and a drilling platform, wherein the small cylindrical end and the drilling platform are integrally formed on the clamp body; the small end of the cylinder is used for clamping the clamp body of the machine tool; the drilling platform is also provided with a small boss and a positioning hole; the compaction assembly is used for compacting the special-shaped part on the drilling platform; during processing, the special-shaped part is positioned on the drilling platform through the small boss and the positioning hole, then is pressed by the pressing component, and then the small end of the cylinder of the clamp body is clamped on a machine tool for processing.
Further, the pressing assembly comprises at least more than three groups of pressing plates and connecting bolts, one end of each pressing plate is connected with the clamp body through the connecting bolts, the other end of each pressing plate presses the special-shaped parts, and the pressing plates are evenly divided along the circumference of the drilling platform.
Furthermore, the pressing plate is L-shaped, a waist-shaped groove is formed in the pressing end face, and the connecting bolt penetrates through the waist-shaped groove to be connected with the clamp body.
Further, the positioning hole corresponds to the left Bian Xiaozhou on the special-shaped part, and when the special-shaped part is processed, the left pin shaft of the special-shaped part is inserted into the positioning hole.
Further, the clamp body, the pressing assembly, the small cylindrical end integrally formed on the clamp body and the drilling platform are made of 45# steel.
The utility model has the beneficial effects that:
(1) The utility model has the advantages of quick and accurate positioning and inner hole alignment of the special-shaped part, and can effectively control the precision of the key size of the processed part and ensure the inner hole size and roundness requirements.
(2) The utility model is convenient for clamping the special-shaped parts, reduces the labor intensity of workers, improves the production efficiency and is suitable for mass production and processing.
(3) The main material of the utility model is mainly 45# steel, and has the advantages of few component parts, low manufacturing cost, simple operation and safe and reliable performance.
