Pneumatic lock clamping tool

Abstract

The invention discloses a pneumatic lock clamping tool. A locating plate (2) is fixed in the center of a base plate (1), a floating end cap (3) is installed in the center of the locating plate (2), locating pins (4) are distributed beside the floating end cap (3), and the locating pins (4) are perpendicular to the face of the locating plate (2); first supports (5) are symmetrically arranged on the left end and the right end of the base plate (1), the top of each first support (5) is provided with a first cylinder (6), and the left first cylinder (6) and the right first cylinder (6) are symmetrically arranged; and piston rods of the first cylinders (6) point to the floating end cap (3) in a downward inclined mode, and the end parts of the piston rods of the first cylinders (6) are provided with pressure heads (7). The invention can complete the pressure installation works of cylinder head forwarding and exhaust valve lock clamping at one time, not only has simple operation and fewer working procedures, but also has high pressure installation speed. The pressure installation efficiency is greatly increased, and the tool can be applicable to different types and states of lock clamp assemblies.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures, and in particular relates to tooling for pneumatic pressure lock clamps. Background technique [0002] The lock clip is an important part of the engine gas distribution system, and it is installed on the intake and exhaust valve rods of the cylinder head. Pressing the lock clip onto the valve stem requires a special device. At present, the press-lock clamp devices used in the industry and the market are all modified from desktop drilling machines, and the shortcomings are: [0003] 1. Only one valve lock clip can be press-fitted at a time. After one lock clip is press-fitted on the same cylinder head, it needs to be rotated 180° and repositioned before another lock clip can be press-fitted. The beat is slow, and the pressing efficiency is not high. [0004] 2. The pressure head is made of ordinary rubber, which is easy to wear and has a short service life. [0005] 3. A press-fitting...

AI Technical Summary

Problems solved by technology

[0003] 1. Only one valve lock clip can be press-fitted at a time. After one lock clip is press-fitted on the same cylinder head, it needs to be rotated 180° and repositioned before another lock clip can be press-fitted. The beat is slow, and the pressing efficiency is not high

[0004] 2. The pressure head is made of ordinary rubber, which is easy to wear and has a short service life

[0005] 3. A press-fitting device is generally for one model. If other models need to be press-fitted, the corresponding positioning mechanism needs to be replaced. The versatility is poor, and the replacement operation is troublesome.
