Embodiment Construction

[0018] For better understanding and implementation, the present invention will be further described below in conjunction with accompanying drawing:

[0019] A special clamp for pistons, including a base 1, above which a left drive assembly, a middle rotation assembly, a clamping assembly and a right support assembly are arranged;

[0020] The left drive assembly mainly includes a support body 2 , a worm 3 , a turbine 4 , a bearing 5 , a main shaft 6 , a transition plate 8 , a connecting shaft 7 and a motor 44 .

[0021] The worm 3 , the turbine 4 , the bearing 5 and the main shaft 6 are arranged inside the supporting body 2 .

[0022] The worm 3 is driven by the motor 44 and transmits dynamic power to the worm gear 4. The worm gear 4 is fixed to the main shaft 6 and drives the connecting shaft 7 and the transition plate 8 to rotate through the bearing 5 together.

[0023] The transition plate 8 and the connecting shaft 7 fixedly connect the left drive assembly and the middle ...

Abstract

The special fixture for the piston comprises a base, and a left driving assembly, a middle rotating assembly, a clamping assembly and a right supporting assembly are arranged on the base; a motor in the left driving assembly drives a transition plate and a connecting shaft to rotate, and the transition plate and the connecting shaft are fixedly connected with the left driving assembly and the middle rotating clamping assembly and enable the middle rotating assembly to swing. The middle rotating assembly can achieve rotation and accurate positioning of the outer main shaft. The clamping assemblies are symmetrically and fixedly connected to the upper end face of the outer main shaft. The clamping assemblies position the end face of a piston and guarantee coarse positioning of a piston pin hole. The clamping assembly positions and clamps the piston in the radial direction through movement of the guide plate and the positioning pin. The right supporting assembly is fixedly connected to the base, and a brake assembly in the right supporting assembly is matched with the left driving assembly to conduct angle positioning on the centering rotating assembly. By means of the structure, the functions of piston positioning clamping, swinging, rotating and variable-angle positioning can be achieved, the piston profile laser cladding process requirements are met, the control precision is high, labor is reduced, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of special clamps, in particular to a special clamp for pistons. Background technique [0002] According to the requirements of the current innovative technology, the top surface of the processed piston needs to be reprocessed by laser cladding to achieve multi-performance requirements such as wear resistance, corrosion resistance, and fatigue resistance. The outer circular surface of the processed piston shape bears the shape of a "drum" as a whole, and the outer surface in a small area below it is circular, but there are still process knife marks, and the depth of the inner circular hole is small. According to the above actual working conditions, it is not conducive to the traditional clamping tools such as collets. In addition, the shape of the piston top is relatively complicated, and laser cladding on its surface requires multi-angle and positioning adjustments, so the requirements for tooling are one ...
