Description

Technical Field

[0001] This utility model relates to the field of shock absorber testing technology, specifically to a shock absorber testing mechanism. Background Technology

[0002] A motorcycle is a two- or three-wheeled vehicle powered by a fuel- or electric motor. It is steered by handlebars using the front wheel and is characterized by its lightness, agility, and speed. It is widely used for commuting, patrolling, and passenger / freight transport. To ensure a smooth ride, motorcycles are typically equipped with shock absorbers. Shock absorbers are an important component of the motorcycle's suspension system; their main function is to absorb and cushion impacts and vibrations during driving, ensuring the vehicle's stability and comfort.

[0003] When testing motorcycle shock absorbers on an electromagnetic vibration test bench, the position of the clamping device cannot be quickly adjusted and fixed, and the motorcycle shock absorber cannot be directly impacted.

[0004] To address the aforementioned technical issues, CN222419521U discloses a quality inspection instrument for motorcycle shock absorber processing. This instrument can evaluate the performance, durability, and reliability of motorcycle shock absorbers under vibration conditions. It can clamp and fix the motorcycle shock absorber using clamping components, reduce damage when the three anti-collision components are impacted, prevent the top of the motorcycle shock absorber from being impacted by a baffle, and clamp and fix motorcycle shock absorbers of different lengths using two auxiliary positioning components. This achieves the effect of quickly clamping and fixing motorcycle shock absorbers of different lengths while avoiding impact.

[0005] The existing technology also has the following shortcomings: it cannot perform repeated impact testing during the testing of motorcycle shock absorbers, which leads to inaccurate impact resistance testing. Utility Model Content

[0018] 1. This utility model, through the coordinated design of the pushing and pressing testing mechanism and the pressing mechanism, enables repeated impact testing during the inspection of motorcycle shock absorbers, thereby improving the impact resistance and accuracy of the test. The repeated rotation of the pushing and pressing testing mechanism generates an impact force, which in turn forms a downward pressure on the pressing mechanism, thus enabling impact resistance testing of the installed and fixed shock absorber, in order to test its impact resistance and durability.

[0019] 2. This utility model, through the combined arrangement of a fixing mechanism and a pressing mechanism, achieves the advantage of clamping and fixing the shock absorber, ensuring that it is in a vertical position during the testing process, thus adapting to the testing location for testing operations. The fixing mechanism can support and clamp the bottom of the motorcycle shock absorber, and the bottom of the pressing mechanism can be used to tighten the top of the motorcycle shock absorber, thereby ensuring that it will not shift during the testing process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a testing mechanism for a shock absorber, including a base 1;

[0027] A fixing mechanism 4 for clamping the shock absorber is provided above the base 1. A pushing test mechanism 2 for testing the shock absorber is provided on the top of the base 1. A pressing mechanism 3 for testing the transmission is provided inside the pushing test mechanism 2. The pressing mechanism 3 includes a power component and a transmission component. The power component is located on the top of the base 1, and the transmission component is located inside the power component. Through the cooperation of the power component and the transmission component, an impact force can be generated by rotation to apply a downward impact force to the pressing mechanism 3, thereby completing the test of the motorcycle shock absorber.

[0028] Specifically, the pressing mechanism 3 includes an elastic component, a pressing component, and a connecting component. The elastic component is located inside the power component, the pressing component is located at the bottom of the elastic component, and the connecting component is located at the bottom of the pressing component. Through the cooperation of the elastic component, the pressing component, and the connecting component, repeated impact testing can be performed based on the above cooperation, and the top of the motorcycle shock absorber can also be fixed by the connecting component.

[0029] Specifically, such as Figure 2 As shown, the power assembly includes an outer frame 21, which is fixedly mounted on the top of the base 1. A motor 22 is bolted to one side of the outer frame 21. This design enables power output during the detection process, allowing it to complete the rotational drive operation.

[0030] Specifically, such as Figure 2 As shown, the transmission assembly includes a main shaft 23, one end of which is keyed to the output shaft of the motor 22. A push block 24 is fixedly mounted on the outer side of the main shaft 23, and the other end of the main shaft 23 is rotatably connected to the outer frame 21. This design enables the transmission of rotational force while also allowing the application of striking force.

[0031] Specifically, such as Figure 3 As shown, the elastic component includes a side plate 31, which is fixedly installed on the inner side wall of the outer frame 21. A spring 32 is welded to the bottom of the side plate 31. This design provides elastic support, thereby facilitating subsequent reset after impact.

[0032] Specifically, such as Figure 3 As shown, the downward pressure assembly includes a push plate 33, which is welded to the bottom end of the spring 32. A limit rod 34 is fixedly installed on the top of the push plate 33. The limit rod 34 slides through the side plate 31 and is located inside the spring 32. This design facilitates downward transmission after being subjected to force, generates downward pressure based on the impact force, and allows for the testing of the installed shock absorber.

[0033] Specifically, such as Figure 3 As shown, the connecting assembly includes a positioning seat 35, which is fixedly installed on the bottom of the lower push plate 33. A bolt 36 is threaded through the interior of the positioning seat 35. This design, in conjunction with the following structure, allows for the installation and fixation of the shock absorber, preventing displacement and ensuring the accuracy of the test.

[0034] Specifically, such as Figure 4As shown, the fixing mechanism 4 includes a bracket 41 and an electric push rod 42. The bracket 41 is fixedly installed on the top of the base 1, and the electric push rod 42 is fixedly installed through the bottom of one side of the outer frame 21. A vertical push plate 43 is fixedly installed at the output end of the electric push rod 42, and a vertical plate 44 is fixedly installed at the bottom of one side of the vertical push plate 43. A positioning rod 45 is fixedly installed on one side of the vertical plate 44. The above design enables the shock absorber to be clamped and fixed before testing to ensure that it is in an upright position.

[0035] Working principle: When clamping the motorcycle shock absorber, first, the motorcycle shock absorber is erected on the top of the bracket 41, and the electric push rod 42 is activated to push the vertical push plate 43, which in turn moves the vertical plate 44 and the positioning rod 45 horizontally until the vertical plate 44 cooperates with the bracket 41 to clamp the outer side of the bottom of the shock absorber. At the same time, the positioning rod 45 will also pass through the connection hole of the shock absorber to match it and ensure the vertical clamping state. At this time, the bottom clamping and fixing work is completed according to the following top fixing.

[0036] Take out bolt 36 directly and pass it through the positioning seat 35 and the top of the shock absorber in sequence. Then tighten the nut that matches bolt 36 to secure and lock the shock absorber. After that, the impact resistance test can be carried out.

[0037] After the shock absorber is fixed and installed as described above, start the motor 22 directly. The motor 22 drives the limit rod 34 to rotate through the main shaft 23. Since the top of the limit rod 34 is protruding, when the protruding part rotates to the bottom, it will directly hit the lower push plate 33 according to the rotational force. At this time, the lower push plate 33 will be pulled down by the force and the shock absorber will be pressed down at the same time. In this way, the impact resistance performance can be tested. A single test cannot detect accurate performance data. It is necessary to continuously rotate and hit the shock absorber and repeat the test.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
