Description

Technical Field

[0001] This utility model relates to the field of shock absorber testing technology, specifically to a height measuring machine for automotive shock absorbers. Background Technology

[0002] Automotive shock absorbers are an important component of a vehicle's suspension system. They are mainly used to control vibrations and impacts generated during vehicle operation, thereby improving ride comfort and driving stability. Before installation, the height or travel of the shock absorber usually needs to be measured to ensure its correct installation and proper functioning in the vehicle or equipment.

[0003] However, in existing technologies, measuring tapes or calipers are usually used to measure the height of the shock absorber after extension and compression. The measurement accuracy is poor, which affects the detection efficiency and detection effect of the shock absorber. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automotive shock absorber height measuring machine, which has the advantage of high detection accuracy. It solves the problem that existing technologies typically use tape measures or calipers to measure the height of shock absorbers after extension and compression, resulting in poor measurement accuracy and affecting the detection efficiency and effectiveness of shock absorbers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a height measuring machine for automobile shock absorbers, including a base plate, wherein a detection mechanism is provided on the base plate;

[0006] The detection mechanism includes a side plate fixedly installed on the upper surface of a base plate, a first top plate fixedly installed on the top of the side plate, a controller fixedly installed on the surface of the side plate, four hydraulic cylinders fixedly installed on the lower surface of the first top plate, a connecting plate fixedly installed at the bottom of the hydraulic cylinders, four rangefinders fixedly installed on the lower surface of the connecting plate, the output end of the rangefinder is electrically connected to the input end of the controller, a top rod is slidably installed on the surface of the connecting plate, a second top plate is fixedly installed at the bottom of the top rod, and a top spring is fixedly installed between the upper surface of the second top plate and the lower surface of the connecting plate.

[0007] Furthermore, a fixed base is fixedly installed on the upper surface of the base plate, and the fixed base corresponds to the rangefinder and the second top plate.

[0008] The advantage of adopting the above-mentioned further solution is that by setting a fixed base, it is easy to fix the shock absorber to be tested on the base plate.

[0009] Furthermore, a circular hole is formed on the surface of the connecting plate, and the push rod is located inside the circular hole, with the outer surface of the push rod in sliding contact with the inner surface of the circular hole.

[0010] The advantage of adopting the above-mentioned further solution is that it facilitates the telescopic movement of the top rod on the connecting plate.

[0011] Furthermore, a first limiting block is fixedly installed on the top of the top rod, and the diameter of the first limiting block is larger than the diameter of the circular hole.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting a first limiting block on the push rod, the push rod can be prevented from detaching from the round hole.

[0013] Furthermore, the diameter of the top spring is larger than the diameter of the circular hole, and the top spring is sleeved on the outer surface of the top rod.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it helps to prevent the top spring from getting stuck in the round hole.

[0015] Furthermore, the connecting plate has two limiting holes on its surface, and the second top plate has two limiting slide rods fixedly installed on its upper surface and located in the limiting holes. The outer surface of the limiting slide rods slides in contact with the inner surface of the limiting holes.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the stability of the second top plate moving on the connecting plate can be improved by setting the limiting slide rod and the limiting hole.

[0017] Furthermore, a second limiting block is fixedly installed on the top of the limiting slide rod, and the diameter of the second limiting block is larger than the diameter of the limiting hole.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it helps to prevent the limiting hole from separating from the limiting slide rod.

[0019] Furthermore, a stabilizing slide rod is fixedly installed between the upper surface of the base plate and the lower surface of the first top plate, and a stabilizing slide cylinder is fixedly installed on the surface of the connecting plate. The stabilizing slide cylinder is sleeved on the outer surface of the stabilizing slide rod, and the inner surface of the stabilizing slide cylinder is in sliding contact with the outer surface of the stabilizing slide rod.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by setting a stabilizing slide and a stabilizing slide bar, the stability of the connecting plate during movement and lifting is improved.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This automotive shock absorber height measuring machine features a rangefinder and a second top plate on a connecting plate, and a fixed base on a base plate. During use, the shock absorber to be tested is fixed to the base plate. A hydraulic cylinder moves the connecting plate and the second top plate downwards, using the second top plate to fix the shock absorber in place. The rangefinder can then be used to measure the height of four points on the end face of the shock absorber, thus ensuring the consistency of the shock absorber's height. This solves the problem of poor measurement accuracy, which is often achieved by using a tape measure or calipers to measure the height of the shock absorber after extension and compression, thus affecting the testing efficiency and effectiveness.

The outer surface of the push rod 8 is in sliding contact with the inner surface of the circular hole 12, which facilitates the extension and retraction of the push rod 8 on the connecting plate 6. A first limiting block 13 is fixedly installed on the top of the push rod 8. The diameter of the first limiting block 13 is larger than the diameter of the circular hole 12. By setting the first limiting block 13 on the push rod 8, the push rod 8 can be prevented from detaching from the circular hole 12. The diameter of the top spring 10 is larger than the diameter of the circular hole 12. The top spring 10 is sleeved on the outer surface of the push rod 8, which helps to prevent the top spring 10 from getting stuck in the circular hole 12.

[0029] The connecting plate 6 has two limiting holes 14 on its surface.

[0031] The working principle of the above embodiments is as follows:

[0032] In use, the shock absorber to be tested is fixed on the base plate 1 by the fixed base 11. The connecting plate 6 and the second top plate 9 are moved downward by the hydraulic cylinder 5, so that the second top plate 9 presses against the top of the shock absorber. At this time, four points on the end face of the shock absorber can be detected by the four rangefinders 7. If the data of one point is higher or lower than the set value, an electrical signal will be sent to the controller 4 and an alarm will be issued.
