In order to comprehensively test and evaluate its performance, a series of professional measuring tools and equipment are needed.

In terms of material and use state evaluation, devices such as hardness tester, leakage tester, fatigue life tester and friction and wear tester are used to ensure that the hydraulic tappet can run stably in the engine.

Inside the base, there is also a vibration strip, which includes several vibration blocks. All the vibration blocks are sequentially attached together and arranged in a row in the horizontal direction. The adjacent two vibration blocks are in smooth contact with each other. The inner surface of the vibration strip is in engagement with the outer surface of the tappet, so that when the tappet rotates around its own axis, the inner surface of the vibration strip can fit the outer surface of the tappet. Each vibration block is in contact with a specific vibration sensor through a corresponding elastic member to detect the distance of vibration block vibration slip.

[0004] However, the detection device in the above-mentioned technology still has the following problems: when fixing the hydraulic tappet, it cannot ensure that the rotation axis of the fixed hydraulic tappet is located directly above the vibration strip, which may cause the rotating hydraulic tappet to produce small amplitude vibration when the outer surface contacts and rubs with the vibration strip during rotation, affecting the accuracy of detection.

[0023] As shown in the utility model, Figure 1 and Figure 2 The side, away from the U-shaped base 1, of the pressure roller 5 is connected with a U-shaped frame 7, both ends of the pressure roller 5 are rotatably connected with both ends of the U-shaped frame 7, one end of the driving motor 6 is fixedly connected with the U-shaped frame 7, the output shaft of the driving motor 6 is fixedly connected with the rotating shaft at one end of the pressure roller 5, and the two lifting assemblies are connected with both ends of the U-shaped frame 7. The U-shaped frame 7 is fixedly installed with the two lifting assemblies, and the driving motor 6 is fixed at one end of the U-shaped frame 7, so that the pressure roller 5 can be rotated in the U-shaped frame 7 under the condition that the U-shaped frame 7 remains stationary, that is, the tappet body 2 can be rotated and measured.
