Problems solved by technology

The existing air valve spring pressing tool is not easy to disassemble, and there is a danger of the pressing tool slipping, causing the air valve block to fly out and hurt people. At the same time, because the same cylinder head is installed multiple times, the efficiency is low; the structure is complicated to carry and inconvenient to use

Abstract

The invention discloses a hold-down device for air valve spring. The hold-down device comprises a stud; a support, an anti-thrust column, a washer and a nut; a tumbler is arranged on a side surface of the anti-thrust column; an inverted U-shaped clamping groove is formed below the tumbler; a lower end of the tumbler is connected with a chuck; a through hole is formed in the center of the chuck. On the basis of an idea of rotation, during assembling, an angle of the anti-thrust column is rotated to change a position of mounting and demounting the air valve spring; due to a planar contact manner between the anti-thrust column and the air valve spring, the spring can be compressed steadily and controllable amount of compression of the spring can be guaranteed; the probability of elastic deformations caused by excessive compression of the spring can be reduced and a purpose of demounting a plurality of air values by mounting the tool once can be achieved, and furthermore, the mounting times of the tool are reduced.

Description

technical field [0001] The invention relates to a pressing device for an air valve spring, which belongs to the technical field of machinery. Background technique [0002] The air valve spring is installed in the air valve and plays a vital role in the working performance of the air valve. In actual work, it is often necessary to replace the air valve and the air valve spring, so it is ready to be pressed, disassembled and installed. The existing air valve spring pressing tool is not easy to disassemble, and there is a danger of the pressing tool slipping, causing the air valve block to fly out and hurt people. At the same time, because the same cylinder head is installed multiple times, the efficiency is low; the structure is complicated to carry And use is also inconvenient. Contents of the invention [0003] In view of this, the present invention provides a pressing device for air valve springs that is easy to carry, easy to operate, and easy to assemble. [0004] It...
