Portable valve assembling and disassembling tooling suitable for multiple series of engines

Abstract

The invention discloses a portable valve assembling and disassembling tooling suitable for multiple series of engines. The portable valve assembling and disassembling tooling comprises a main body comprising a push rod, a connecting mechanism and a support body, and the upper end of the support body is movably connected with the lower end of the push rod through the connecting mechanism; and a mounting frame arranged on an engine cylinder head cover and comprises a supporting arm and two groups of supporting legs. According to the portable air valve assembling and disassembling tooling suitable for the multiple series of engines provided by the invention, an air valve spring upper base, an air valve spring or an air valve lock clamp and an air valve can be independently disassembled by using the tooling under the condition that an air cylinder cover does not need to be disassembled, and the requirement of the tooling for the peripheral space of the air valve is low; thrust is transmitted between the push rod and the support body through balls, friction force is greatly reduced, damage of the tooling to engine parts is reduced, the influence of a spring spiral structure on the support body is reduced, the support body is stressed in a balanced mode, the situations of tooling inclination and clamping deviation are avoided, and the safety coefficient is higher.

Description

Technical field [0001] The present invention relates to the field of engine industries, and in particular, to a portable valve unparalleled device suitable for multiple series engines. Background technique [0002] The engine into the exhaust gas door mechanism is usually composed of valve, valve springs, valve spring, and valve lock clamps. When the valve is faulty or performs special tests such as valve lift, the valve is required to disassemble the valve, in order to facilitate people to disassemble the valve. People invented some valve tooling fixtures. With the rapid development of society, people have continuously improved the requirements of valve tooling fixtures, causing existing valve tooling fixtures to meet people's use requirements; [0003] The existing valve tooling fixture has a certain drawback in use. First, the existing valve tool fixture has a high requirements of the peripheral space, need enough space to the tooling activities, clamping the valve spring, sec...

AI Technical Summary

Problems solved by technology

[0002] The intake and exhaust valve mechanism of the engine is usually composed of valves, valve springs, valve spring upper seats and valve lock clips. When the valve fails or special tests such as valve lift are performed, the valve needs to be disassembled. In order to facilitate people to disassemble the valve , people invented some valve fixtures, with the rapid development of society, people's requirements for valve fixtures are constantly improving, resulting in the existing valve fixtures can not meet people's use requirements;

[0003] There are certain disadvantages in the use of existing valve tooling fixtures. First, the existing valve tooling fixtures have high requirements for the surrounding space of the valve. There needs to be enough space for the tooling to move and clamp the valve spring. Secondly, the existing valve tooling The tooling fixture can only be performed manually. If the valve spring has a large elastic force, it is difficult to compress the valve spring. Finally, when the existing valve tooling fixture clamps and compresses the spring, due to the helical structure of the spring, the two clamping arms of the tooling The force received is unbalanced, and the tooling will be tilted and clamped, which cannot meet people's use requirements. Therefore, we propose a portable valve assembly and disassembly tooling suitable for multi-series engines.
