Combined sliding wheel for hole grinding processing of cylinder body and manufacturing method of combined sliding wheel

Abstract

The invention relates to a combined sliding wheel for hole grinding processing of a cylinder body and a manufacturing method of the combined sliding wheel. The combined sliding wheel comprises a left wheel body, a right wheel body and countersunk screws, wherein one end surface of the left wheel body and one end surface of the right wheel body are attached, the left wheel body and the right wheel body are fixedly connected through the countersunk screws, thread connection holes are formed in the middles of the left wheel part and the right wheel part, annular teeth are arranged on the excircle surfaces of the left wheel body and the right wheel body, and an annular groove which shares the same axis with the thread connection holes is formed in the end surface attaching position of the left wheel body and the right wheel body. The manufacturing method is as follows: 1), casting of a single part; 2), processing of separated parts; and 3), assembling processing. The combined sliding wheel and the manufacturing method have the advantages of reasonable structure design, convenience in production and processing and the like, power transmission is realized through meshing action of an external gear driven by a motor and the annular teeth, so that a single-DOF (degree of freedom) moving platform or a two-DOF moving platform moves, and the movement requirement for actual production processing is met; and with adoption of single-part processing and assembling processing combined manner, the structure feature and size can meet the matching requirement, and batch production processing is easy to realize.

Description

technical field [0001] The invention relates to an auxiliary part for grinding holes of a brake hydraulic cylinder, in particular to a sliding combination wheel for grinding holes of a cylinder body and a manufacturing method thereof. Background technique [0002] In the process of grinding the hole of the brake hydraulic cylinder with the grinding machine, there are usually two movement modes. The first is that the tool rotates and the workpiece is fed to complete the entire hole grinding process; the second is that the tool rotates. And feeding, the workpiece is still. For the first type of motion, the workpiece is installed on a single-degree-of-freedom motion platform or a two-degree-of-freedom motion platform. The principles of these motion platforms mostly use the motor to directly drive the screw mechanism to achieve single-degree of freedom or two-degree-of-freedom. The movement, the structural connection is relatively simple, but since the motor needs to be arrange...

Problems solved by technology

For the first type of motion, the workpiece is installed on a single-degree-of-freedom motion platform or a two-degree-of-freedom motion platform. The principles of these motion platforms mostly use the motor to directly drive the screw mechanism to achieve single-degree of freedom or two-degree-of-freedom. The movement, the structural connection is relatively simple, but since the motor needs to be arranged at both ends of the axial position of the screw mechanism, it will occupy a large space volume, making the overall size larger and restricting the movement of the mechanism. At the same time, due to the large exposed parts of the platform as a whole, the safety performance is low during the movement of the platform, and it is easy to touch the staff, which poses a threat to the personal safety of the staff.
