Problems solved by technology
However, for some YV series engine cylinder blocks, due to the unique W-shaped structure of the cylinder block, the shape is more complicated, and there are many positioning points and clamping points that are relatively hidden, which makes it difficult to locate and clamp the W-shaped cylinder block with traditional clamps. The problem

The invention discloses a clamp for processing two end faces of a W-shaped cylinder body, a cylinder hole and a spindle hole, belongs to the technical field of cylinder body processing, and solves theproblem that the conventional clamp is difficult to clamp the W-shaped cylinder body and cannot be processed. The clamp comprises a base and pressure plates, wherein the pressure plates are slidinglyinstalled on the four corners of the base through support columns; locking assemblies are arranged between the pressure plates and the base; one ends in the two pressure plates at the right side of the base are provided with plane pressure heads; one ends in the pressure plates at the rear left side of the base are provided concave pressure heads; one ends in the pressure plates at the left frontside of the base are provided with convex pressure heads; positioning assemblies are arranged on the base below the plane pressure heads; and a support assembly is arranged on the base. The clamp forprocessing two end faces of the W-shaped cylinder body, the cylinder hole and the spindle hole provided by the invention can realize the fast and accurate positioning and clamping of the W-shaped cylinder body, which helps to improve the machining precision.
Description
technical field [0001] The invention relates to the technical field of cylinder block processing, more specifically, it relates to a fixture for processing both ends of a W-shaped cylinder block, a cylinder hole and a spindle hole. Background technique [0002] During the production and processing of the cylinder block, the processing of both ends of the cylinder block, cylinder bore and spindle hole is an essential process. For general cylinder block processing, the bottom surface of the cylinder block and the positioning pin holes on the bottom surface are usually used for positioning. In the case of one clamping, the two ends of the cylinder block, the cylinder hole and the spindle hole are processed by a five-axis machining center. However, for some YV series engine cylinder blocks, due to the unique W-shaped structure of the cylinder block, the shape is more complicated, and there are many positioning points and clamping points that are relatively hidden, which makes it...
