AI Technical Summary

Technical Problem

The cylinder high-pressure cylinder lacks a positioning structure during the return to the factory, which leads to the problem of left and right position deviations in the high-pressure cylinder.

Method used

A cylinder-type high-pressure cylinder positioning structure is designed, including the bearing seat shoulder, the first high-pressure cylinder vertical pin limit and the second high-pressure cylinder vertical pin limit respectively located on both sides of the bearing seat shoulder, and the fixed pin and limit parts are provided to ensure that when the vertical pin is returned to the factory to process, the combination of the fixed pin and the limit part can limit the left and right movement of the vertical pin, and fine-tune is adjusted by adapting to the actual open distance through the limit part.

Benefits of technology

It effectively prevents the position deviation of the cylinder high-pressure cylinder during the return to the factory, ensures the accuracy and stability of positioning, and is used in conjunction with the pin puller through threaded holes, which facilitates the disassembly operation of the staff.

Abstract

The invention discloses a barrel-type high-pressure cylinder positioning structure, which relates to the technical field of barrel-type high-pressure cylinder positioning, and comprises a bearing seat convex shoulder, and a first high-pressure cylinder vertical pin limiting device and a second high-pressure cylinder vertical pin limiting device which are respectively positioned on two sides of the bearing seat convex shoulder, two groups of fixing bolts and two groups of limiting pieces are arranged; a fixing plug pin and a limiting piece are arranged between the bearing seat protruding shoulder and the first high-pressure cylinder vertical pin limiting device, and a fixing plug pin and a limiting piece are arranged between the bearing seat protruding shoulder and the second high-pressure cylinder vertical pin limiting device. The fixing plug pins are arranged between the bearing seat protruding shoulder and the first high-pressure cylinder vertical pin limiting device, and the fixing plug pins are arranged between the bearing seat protruding shoulder and the second high-pressure cylinder vertical pin limiting device. According to the high-pressure cylinder vertical pin limiting device, the effect of limiting left and right movement of the first high-pressure cylinder vertical pin limiting device and the second high-pressure cylinder vertical pin limiting device can be achieved during vertical pin factory returning machining, the limiting piece can adapt to the actual opening distance for fine adjustment, the first threaded hole capable of being used in cooperation with a pin puller is further formed, and a worker can disassemble the high-pressure cylinder vertical pin limiting device conveniently.
