Description

Technical Field

[0001] The utility model relates to the technical field of rocker arm assembly pressure testing, in particular to a long-life rocker arm assembly pressure testing device. Background Art

[0002] The rocker arm assembly is an important part of the engine valve train. Its main function is to change the direction of the thrust of the valve train and drive the valve to open. The rocker arm is a double-arm lever with two arms of unequal length. Although the valve train that uses the rocker arm to drive the valve to open has a relatively complex structure, the cam lift can be reduced when the valve lift is constant by selecting the length of the two ends of the rocker arm. At the same time, the adjustment of the valve clearance is also relatively convenient.

[0003] A rocker arm assembly is composed of a plurality of rocker arms, and most of the rocker arm assembly pressure testing devices in the prior art can only perform pressure testing operation on one rocker arm at a time, which reduces work efficiency and cannot adapt to rocker arms of different lengths, thus reducing practicality.

DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a long-life rocker arm assembly pressure testing device, comprising:

[0023] A base 1, a fixing plate 2 is fixedly arranged on the base 1, a positioning rod 3 is hingedly arranged on one side of the fixing plate 2, so that the outer end of the positioning rod 3 can swing up and down, a supporting plate 4 is fixedly arranged on the base 1, a placement groove 5 is arranged on the supporting plate 4, the placement groove 5 is arranged in cooperation with the positioning rod 3, so that the positioning rod 3 can be stuck in the placement groove 5, a plurality of marks 18 are arranged on the positioning rod 3, and the plurality of marks 18 are arranged in cooperation with the plurality of cylinders 7, so that the staff can position the rocker arm conveniently, so that the rocker arm and the corresponding cylinder 7 are on the same vertical line;

[0024] A U-shaped frame 6 is fixedly arranged on the base 1, and a plurality of pressure test components are fixedly arranged on the U-shaped frame 6. The pressure test components include a cylinder 7, a lifting plate 8 and two moving columns 15. The cylinder 7 passes through the top of the U-shaped frame 6 and is fixedly arranged. The lifting plate 8 is fixedly arranged at the output end of the cylinder 7. The two moving columns 15 are slidingly arranged against the bottom of the lifting plate 8. The abutting arrangement can improve stability. A pressing block 16 is fixedly arranged at the bottom of the two moving columns 15. A rubber protective pad 17 is fixedly arranged at the bottom of the two pressing blocks 16. The two rubber protective pads 17 are arranged in coordination with the corresponding marks 18, so that the two rubber protective pads 17 and the two pressing blocks 16 can be pressed on the two ends of the rocker arm, so as to perform a pressure test operation. The rubber protective pad 17 can play a protective role to avoid crushing the rocker arm. An adjustment component is arranged between the two moving columns 15 and the lifting plate 8;

[0025] The adjusting assembly includes a first threaded rod 11 and a second threaded rod 12. Limiting plates 9 are fixedly arranged at both ends of the bottom of the lifting plate 8. One end of the first threaded rod 11 is fixedly arranged on one end of the second threaded rod 12. The outer end of the first threaded rod 11 is rotatably arranged on the inner side of one of the limiting plates 9. A round rod 13 is fixedly arranged on the outer end of the second threaded rod 12. The round rod 13 passes through the limiting plate 9 on the other side and is rotatably arranged with the limiting plate 9. A crank 14 is fixedly arranged on the outer end of the round rod 13. The crank 14 can facilitate the staff to rotate the first threaded rod 11 and the second threaded rod 12. The threads of the first threaded rod 11 and the second threaded rod 12 are arranged in opposite directions. The first threaded rod 11 and the second threaded rod 12 respectively pass through the moving column 15 on the same side and are threadedly connected with the moving column 15 at the same time. When the first threaded rod 11 and the second threaded rod 12 are rotated by the crank 14, the two moving columns 15 can be driven to move simultaneously and in opposite directions.

[0026] A guide rod 10 is fixedly arranged on the inner side of the two limit plates 9. The guide rod 10 passes through the two movable columns 15 and is slidably arranged with the movable columns 15. The two guide rods 10 guide the two movable columns 15, making the movement and adjustment of the two movable columns 15 more stable.

[0027] The detailed working process of the utility model is as follows:

[0028] 1. When in use, the staff first lifts the outer end of the positioning rod 3, then sets multiple rocker arms on the positioning rod 3, then clamps the outer end of the positioning rod 3 in the placement groove 5, and then evenly places the multiple rocker arms according to the mark 18, and then starts multiple cylinders 7, and drives the lower lifting plate 8 to move downward through the cylinder 7. The lifting plate 8 drives the two pressing blocks 16 to move downward through the two moving columns 15, and presses against the two ends of the rocker arm. Continue to move downward to perform the pressure test operation. After the operation is completed, the two pressing blocks 16 are driven by the cylinder 7 to move upward and release the rocker arm, and finally the positioning rod 3 is lifted upward to take out the rocker arm;

[0029] 2. When adjusting the spacing between the two pressing blocks 16, the staff drives the round rod 13 to rotate through the crank 14, and the round rod 13 drives the first threaded rod 11 and the second threaded rod 12 to rotate. The first threaded rod 11 and the second threaded rod 12 drive the two pressing blocks 16 to move simultaneously and in opposite directions through the two moving columns 15, so that adjustment can be made.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
