[0039] like Figures 1-4 As shown, a face cover softness and hardness tester mainly includes: a shell 1, a displacement detection meter 2 and a telescopic rod 3.

[0040] The shell 1 is the structural support for the entire hardness and softness tester and provides an installation location for other components. The shell 1 includes a shell body 10, a shell cover 11 and a pressure plate 12; the shell cover 11 and the shell body 10 are detachably connected by screws. When the shell cover 11 is removed from the shell body 10, the telescopic rod 3 can be installed into the shell 1, or the telescopic rod 3 can be removed from the shell 1. That is, the purpose of setting the shell cover 11 is to install the telescopic rod 3. Specifically, the diameter of the limiting top cover 33 on the top of the telescopic rod 3 is larger than the diameter of the telescopic rod 3, and the limiting top cover 33 and the telescopic rod 3 are fixedly connected by threads, that is, the limiting top cover 33 can be regarded as a part of the telescopic rod 3. If the shell cover 11 is not set, the large diameter top cover cannot be installed. The pressure plate 12 is set as a flange plate. The diameter of the pressure plate 12 is much larger than the diameter of the shell body 10, which is convenient for setting the hardness and softness tester on the face cover for testing and ensuring that it can be placed stably. The pressure plate 12 and the shell body 10 are detachably fixedly connected by a plurality of screws to facilitate assembly and disassembly. The abutment head 31 of the telescopic rod 3 is arranged on the pressure plate 12 so as to be telescopically movable. A gripping portion 100 for human hand gripping is formed on the shell 1. The shell body 10 of this embodiment is roughly cylindrical in structure, which is convenient for human hand gripping and easy to carry. Preferably, a plastic bushing is also provided on the pressure plate 12, and the telescopic rod 3 is passed through the plastic bushing and can be telescopically movable, thereby ensuring that the telescopic movement of the telescopic rod 3 is reliable and convenient for replacement when the plastic bushing is worn.

[0041] The displacement detection table 2 is arranged on the top of the shell 1. In this embodiment, the displacement detection table 2 is preferably a digital display micrometer. The displacement of the telescopic rod 3 can be intuitively and accurately fed back through the digital display micrometer. The accuracy can even reach 0.001 millimeter, and the digital display micrometer has the characteristics of high stability and high precision.

[0042] The telescopic rod 3 is movably arranged on the shell 1, and one end of the telescopic rod 3 extends out of the shell 1 and is configured as the abutting head 31. As a preferred arrangement, the end of the telescopic rod 3 away from the abutting head 31 is movably arranged against the displacement detection table 2, and the displacement detection table 2 can detect the movement stroke of the telescopic rod 3. The retraction displacement of the telescopic rod 3 can be intuitively fed back through the displacement detection table 2. A spring 30 is arranged on the telescopic rod 3, and the telescopic rod 3 has a limiting structure 32. In this embodiment, the end of the telescopic rod 3 close to the abutting head 31 has a limiting step 34. A gasket is arranged on the telescopic rod 3 and abuts against the limiting step 34. The gasket is configured as the limiting structure 32 and is made of metal. That is, one end of the spring 30 abuts against the metal gasket, and the other end of the spring 30 abuts against the shell 1. During the retraction of the telescopic rod 3 into the shell 1, the spring 30 can be compressed through the metal gasket. A limiting top cover 33 is arranged on the end of the telescopic rod 3 away from the abutting head 31, that is, the top end. The limiting top cover 33 is detachably connected with the telescopic rod 3, and the limiting top cover 33 can limit the telescopic rod 3 from being separated from the shell 1. The limiting top cover 33 movably abuts against the displacement detection table 2.

[0043] In actual use, when the abutting head 31 abuts against the surface of the surface sleeve 4 to be detected, the telescopic rod 3 is retracted to the side of the shell 1 due to the reaction force of the surface sleeve 4 to be detected, the spring 30 is compressed, and the telescopic rod 3 triggers the displacement detection table 2. The displacement of the telescopic rod 3 can be directly obtained from the displacement detection table 2.

[0044] Preferably, the surface sleeve hardness detector of this embodiment further comprises a force sensor, preferably a patch type force sensor. The force sensor can be attached to the surface of the surface sleeve 4 to be detected and detect the force applied to the surface sleeve 4 to be detected. That is, when the hardness of multiple surface sleeves is detected, the setting of the force sensor can conveniently control the size of the applied force to be fixed, control the variable, and directly judge the hardness of the surface sleeve through the retraction stroke of the telescopic rod 3 and the reading of the displacement detection table 2. As a preferred arrangement, in actual use, the self-gravity of the surface sleeve hardness detector can be directly abutted against the surface of the surface sleeve 4 to be detected for detection. The self-gravity is a constant value, and the applied force can also be controlled to be constant.

[0045] When different surface sleeves 4 to be detected are detected: under the condition that the applied force is the same, the greater the stroke of the telescopic rod 3, the greater the detection result of the displacement detection table 2, which indicates that the hardness of the surface sleeve is smaller; and the smaller the stroke of the telescopic rod 3, the smaller the detection result of the displacement detection table 2, which indicates that the hardness of the surface sleeve is greater.

[0046] Need to explain: F (exert) = F (spring) + F (cushion), that is, the force exerted is equal to the reaction force of the spring plus the reaction force of the cushion. And F (spring) = K (spring) * S (micrometer), F (cushion) = K (cushion) * S (micrometer), so, F (exert) = K (spring) * S (micrometer) + K (cushion) * S (micrometer), K is the stiffness coefficient corresponding to the material, S is the displacement value of the telescopic rod 3. It can be seen that if F (exert) is constant, the greater K (cushion) is, that is, the greater the hardness of the cover is, the smaller S (micrometer) is; and the smaller K (cushion) is, that is, the smaller the hardness of the cover is, the larger S (micrometer) is.

[0047] In the scheme, when the softness and hardness of the cover are detected, the abutting head 31 is pressed on the cover 4 to be detected, the abutting head 31 is sunk to the side of the cover, and the reaction force of the cover on the abutting head 31 will make the telescopic rod 3 retract to the side of the shell 1, at the same time, the spring 30 is compressed, and the displacement detection table 2 is triggered, so that the moving distance of the telescopic rod 3 can be obtained by reading the data of the displacement detection table 2, and the softness and hardness of the cover can be obtained. For example, under the condition of the same force, the deeper the abutting head 31 sinks, the larger the reading of the displacement detection table 2 is, and the softer the cover is; the shallower the abutting head 31 sinks, the smaller the reading of the displacement detection table 2 is, and the harder the cover is. The structure of the cover softness and hardness detector is simple, convenient to carry, and convenient and efficient to detect. The cover softness and hardness detector can quickly respond and detect when internal problems are analyzed, external standards are set, evaluated, or whole vehicle road tests are conducted, and can provide effective evaluation basis.
