Air door lock block press-mounting tool

Abstract

The invention discloses an air door lock block press-mounting tool. A vertical column, a turntable locking mechanism and an inclined turntable assembly are mounted on a bottom plate; the turntable assembly is used for clamping and positioning a cylinder cover; the turntable assembly can be locked through the turntable locking mechanism in a first press-mounting position and a second press-mounting position after being rotated by 180 degrees correspondingly; a pressing rod supporting assembly and a pressing rod assembly are sequentially mounted on the vertical column in a sleeving mode; the pressing rod supporting assembly comprises a mounting sleeve, a connecting rod and a pressing rod supporting block; the mounting sleeve is axially and fixedly mounted on the vertical column in a sleeving mode; the pressing rod assembly comprises a rotating block, a horizontal rod, a pressing head and a hinged block; the rotating block is rotatably mounted on the vertical column in a sleeving mode; one end of the horizontal rod is hinged on the rotating block in an up-down swinging mode; and the hinged block is mounted on the horizontal rod in a sleeving mode and hinged to the upper end of the pressing head together. Press-mounting of an air inlet door lock block and an air outlet door lock block can be completed through one-time clamping, the clamping frequency is decreased, the press mounting efficiency is improved, easiness and labor saving are achieved, and through replacement of the turntable assembly, press-mounting of cylinder cover air door lock blocks of different types and different positions can be met.

Description

technical field [0001] The invention relates to a press-fitting tool for an engine valve lock block, which is used for press-fitting two valve lock blocks into a groove formed between a valve spring seat and a valve. Background technique [0002] The valve lock block is an important part on the cylinder head, combined with Figure 4 — Figure 6 As shown, a valve 1, a valve spring 2, a valve spring seat 3 and a valve lock block 4 are installed in the cylinder head 5. The valve lock block 4 needs to be pressed into the groove formed between the valve spring seat 3 and the valve 1 . When installing, compress the valve spring to a certain length to expose the groove on the valve, push the two valve lock blocks to the position lower than the groove on the valve at the same time, and then reset the valve spring. During the reset process of the valve spring, use The tapered hole on the valve spring seat gathers the valve lock block and locks it into the corresponding groove on th...

AI Technical Summary

Problems solved by technology

[0003] Usually, the method of manually pressing and installing the valve lock block is used. Because the valve is set at an angle, it needs to be pressed and installed, which is inconvenient to operate. In addition, because the valve spring itself has a relatively large compression resistance, it is necessary to overcome the tension of the valve spring during the installation process. The cylinder head has intake and exhaust valves on both sides, and workers are prone to fatigue due to continuous operation
