Description

Diesel engine valve disassembly device

technical field

The invention relates to a dismounting tool, in particular to a diesel engine valve dismounting device which can conveniently disassemble the diesel engine valve mechanism.

Background technique

The disassembly and assembly of the valve mechanism on the cylinder head is an important process in the disassembly process of the diesel engine. At present, the disassembly and assembly of the valve mechanism of the diesel engine in the production line is carried out with a special equipment, but the equipment is heavy and the investment is relatively high. Large, mostly used for disassembly and assembly of diesel engine valve trains in mass production and complete production. However, in some tool workshops or laboratories, due to the small number of installed machines, there are generally special disassembly and assembly equipment for diesel engine valve trains. But this method is cumbersome and requires two people to move the cylinder head to the drilling machine, which is time-consuming and laborious, and the disassembly efficiency of the diesel engine valve train is extremely low.

Contents of the invention

The technical problem to be solved by the present invention is to provide a valve disassembly device for a diesel engine, which is flexible in movement, easy to operate, greatly reduces the waste of manpower and time, and improves the disassembly efficiency of the valve mechanism of a diesel engine.

In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a diesel engine valve dismounting device, including a bracket, a cross bar is arranged on the bracket, one end of the pressure bar is sleeved on the cross bar, and the other end is provided with a driving pressure bar and a cross bar. It is a pivoting force applying device, the pressing rod is sleeved with a sleeve, and the sleeve is hinged with a valve pressing device that can be sleeved on the valve of the diesel engine to compress the valve spring.

As an improvement, the compressed valve device includes a ring sleeve that can compress the valve spring, and the ring sleeve is provided with a sleeve hingedly connected with the sleeve.

As a further improvement, the height of the cross bar on the support can be adjusted.

As a further improvement, threaded fit is used between the sleeve and the cross bar.

As a further improvement, the force applying device includes a chain at the end of the pressure rod, and a pedal connected with the chain.

As a further improvement, the bracket is provided with a base for placing the valve dismounting device on the cylinder head of the diesel engine.

The above-mentioned technical scheme adopts a diesel engine valve dismounting device, adopts a cross bar on the bracket, one end of the pressure bar is sleeved on the cross bar, and the other end is provided with a force that drives the pressure bar to rotate with the cross bar as a pivot. device, a sleeve is set on the pressure rod, and the sleeve is hinged with a pressure valve device that can be set on the diesel engine valve to compress the valve spring, so that the pressure valve device, the cross bar, and the pressure rod form a lever mechanism. Driven by the drive, the pressure valve device will give the valve spring a downward force under the drive of the pressure rod, and the spring will be pressed down. At this time, the operator can install or remove the spring lock clip to disassemble the valve. The device is flexible in movement and convenient in operation, reduces the waste of manpower and time, and improves the disassembly and assembly efficiency of the valve mechanism of the diesel engine. The pressure valve device adopts a ring sleeve that can compress the valve spring, the ring sleeve is provided with a sleeve hingedly connected with the sleeve, and the force applying device adopts a chain at the end of the pressure rod, and a pedal is connected with the chain. The structure is simple and the use is convenient. The height position of the cross bar on the bracket is adjustable, which facilitates the adjustment of the device. Thread fit is adopted between the sleeve and the cross bar, which avoids the relative displacement between the sleeve and the cross bar when the valve mechanism is disassembled, and ensures the smooth progress of the disassembly work.

Detailed ways

As shown in Figure 1, the diesel engine valve disassembly device includes a bracket 1. In order to facilitate the use of the device on the diesel engine cylinder head, the bracket 1 is provided with a base 11 that can place the valve disassembly device on the diesel engine cylinder head. There is a cross bar 2 on the bracket 1, the cross bar 2 can be fixed on the bracket 1 by bolts, and the height of the cross bar 2 can be adjusted according to the needs of actual operation, and one end of the pressure bar 3 is set on the cross bar 2 And the other end is provided with the force application device 6 that drives pressure bar 3 to pivot with cross bar 2, and pressure bar 3 can slide on cross bar 2, to facilitate the adjustment when dismounting valve mechanism, and force application device 6 then can adopt to be provided with chain at the end of depression bar 3, be provided with pedal with chain connection, during use, operator's foot steps on pedal and can drive depression bar 3 to rotate, and sleeve 5 is arranged on depression bar 3 suit, sleeve 5 is hinged with a depressing valve device 4 that can be set on the diesel engine valve to compress the valve spring. Through the hinge connection between the sleeve 5 and the depressing valve device 4, the sleeve 5 and the depressing valve device 4 can be relatively rotated. In order to ensure that the force direction of the valve device 4 is vertically downward, such as the valve device 4 can be installed on the pressure rod 3 with a pin, and an interference fit can be used between the pin and the valve device 4, and the sleeve 5 There is a gap fit between them to ensure that the direction of the acting force is vertically downward; The sleeve frame 41 that tube 5 is hinged.

When using this diesel engine valve disassembly device to disassemble and assemble the diesel engine valve mechanism, put the cylinder head on the base 11, place the adjusting ring sleeve 42 on the appropriate position of the valve on the cylinder head, step on the pedal with your feet and press down hard, the ring sleeve 42 Give the valve spring a downward force under the drive of the depression bar 5, the spring is pressed down, the operator just can load on or take off the spring lock clip at this moment, thereby carried out the dismounting of valve. And, in order to be able to adjust the position of the sleeve 5 on the pressure rod 3 conveniently to facilitate the disassembly and assembly of the valve, and to avoid relative displacement between the two when disassembling, the sleeve 5 and the cross bar 2 can be With thread fit.
