Abstract
The utility model relates to the technical field of diesel engine assembly, in particular to a diesel engine valve collet press-fitting device which can facilitate the installation of a valve collet, improve the efficiency and avoid damaging products.
Description
Technical Field
The utility model relates to the technical field of diesel engine assembly, in particular to a diesel engine valve lock clamp press-fitting device.
Background
On a diesel engine, the valve mechanism is the heart of the diesel engine and is also a main transmission part of the diesel engine. The valve mechanism comprises a valve group and a valve transmission group, wherein the valve group mainly comprises a valve, a valve guide pipe, a valve oil seal, a valve spring seat, a valve lock clamp and the like. The valve is arranged in a groove on the top end of the valve, the valve is clamped by a valve lock clamp in order to enable the valve to return under the action of a valve spring, and then the opening and closing actions of the valve are controlled by the transmission of a cam shaft to provide power for a diesel engine. In order to ensure the reliability and stability of the valve group, a groove is formed in the top end of the valve, and the valve collet is arranged in the valve top mounting groove through the cooperation of the valve spring seat. Since the valve spring in its free state is of a size that is not fittable at this time above the valve recess position, the valve spring must be placed in compression and below the valve recess position before the valve collet can be fitted in the valve recess. Often need assemble with the help of knocking tools, spring compressor etc. in the use, intensity of labour is big, assembly efficiency is low, moreover causes the damage of product very easily.
Disclosure of Invention
In order to solve the problems that the existing valve collet is difficult to install and low in efficiency and is easy to damage products, the utility model provides a diesel engine valve collet press-fitting device which can conveniently install a valve collet, improves efficiency and does not damage products.
The technical scheme is as follows: the utility model provides a diesel engine valve collet pressure equipment device, its includes table surface, its characterized in that, install side limiting plate and supporting mechanism on the table surface, be provided with the depression bar that can overturn on the supporting mechanism through the round pin axle, slidable mounting has the slider on the depression bar, the slider bottom is fixed with the location briquetting, the through-hole has been seted up on the location briquetting.
The support mechanism is further characterized by comprising an auxiliary hook plate fixed on the workbench surface, wherein a pressure bar support is arranged on the auxiliary hook plate through a hook pin, one end of the pressure bar is hinged with the pressure bar support through the pin shaft, and the other end of the pressure bar is provided with a holding handle;
the lower part of the through hole is a cylindrical surface spigot matched with the valve spring seat;
two layers of pin holes which are four rows and matched with the hanger pins are formed in the auxiliary hook plate.
After the utility model is adopted, the cylinder cover is placed on the workbench surface, the side limit plate is used for pre-limiting, the sliding block is moved back and forth, the positioning pressing block is placed on the valve spring seat, and the valve spring is pressed down by utilizing the compression bar through external pressure and manual assistance, so that the valve spring is compressed, the valve lock clamp is driven to slide downwards and be clamped and assembled in the groove at the top end of the valve, the operation is simple and convenient, the efficiency is high, and the damage to a product is avoided; further, the cylinder cover is limited through the side limit plate, and the compression bar support and the compression bar can be adjusted by the aid of the through holes in the hook plate, and the positions of the compression bar support and the compression bar are corresponding to the positions of the air valves on the cylinder cover in the same plane, so that the cylinder cover is convenient to incline in the press mounting process, and the stability of press mounting is maintained.
