For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] The utility model provides a high temperature simulation mechanism and hardness detection device for nylon material, this high temperature simulation mechanism and hardness detection device for nylon material include bearing station 1, the inside of bearing station 1 is provided with heating mechanism, heating mechanism includes the heating pipe 2 of setting in the inside of bearing station 1, the heating pipe 2 is evenly set in the inside of bearing station 1, the both sides of heating pipe 2 are provided with pressurizing mechanism, thereby in the hardness detection of nylon material, can simulate the high temperature environment of motor 15 failure, and then make the hardness detection result of nylon material more real and accurate.

[0026] In the embodiment, the structure of the hardness detection device for nylon material is shown in Figure 1 、 Figure 2 and Figure 4 , wherein Figure 2 、 Figure 4 only shows part of the hardness detection device, mainly showing the part related to the utility model.

[0027] The hardness detection device of the utility model includes bearing station 1, device main body 16, hydraulic device (not shown in the drawing), extrusion module 17, pressure blade (not shown in the drawing) and positioner 18. As shown in Figure 1 and Figure 2 , the high temperature simulation mechanism includes heating mechanism, and the heating mechanism includes a plurality of heating pipes 2 arranged horizontally inside the bearing station 1, the heating pipes 2 are evenly arranged inside the bearing station 1, and the both sides of the heating pipes 2 are provided with pressurizing mechanism.

[0028] The extrusion module 17 and pressure blade of the hardness detection device for nylon material in the prior art can only detect the hardness of nylon material in normal environment, and when facing nylon material in special occasions, such as nylon material used for motor 15 shell, because the nylon material used for motor 15 shell is usually damaged in high temperature environment, the authenticity and accuracy of the detection result will be reduced. After the hardness detection device for nylon material adopts the hardness detection device for nylon material of the embodiment, the problem that the hardness detection device is difficult to simulate high temperature environment, resulting in the authenticity and accuracy of the detection result when detecting nylon material used in special occasions, is avoided, and the applicability and accuracy of the hardness detection device are improved.

[0029] In the embodiment, as shown in Figure 1 and Figure 4 , the bottom end of the extrusion module 17 is designed as a spherical shape, which can improve the authenticity of the film pressing detection compared with the prior art, and further improve the accuracy of the hardness detection result. In another embodiment, the bottom end of the extrusion module 17 can also be designed as a square shape in the prior art, so as to improve the standardization and comparability of the detection data.

[0030] In the embodiment, as shown in Figures 1 to 4 The pressing mechanism comprises a plurality of pressing rods 3 vertically arranged on both sides of the heating pipe 2, which are uniformly arranged on the inner side of the bearing table 1, are slidingly connected to the support guide frames 4, are fixedly connected between the support guide frames 4, are fixedly installed on the inner side of the bearing table 1, and are provided with extrusion blocks 5 at the bottom ends, and the bottom ends of the extrusion blocks 5 are provided with lifting assemblies. In this way, when the hardness of the nylon material is detected, the lifting assembly can drive the extrusion blocks 5 to move, so that the extrusion blocks 5 extrude the nylon material through the pressing rods 3, thereby simulating the extrusion effect of the internal gas expansion on the nylon shell when the motor 15 fails at high temperature, and further improving the authenticity and accuracy of the hardness detection result of the nylon material.

[0031] In the embodiment, as shown in Figure 3 The pressing rod 3 comprises a pressing top cover 6, a pressing lower rod 7 slidingly installed at the bottom end of the pressing top cover 6, and a spring 8 connected between the pressing top cover 6 and the pressing lower rod 7. In this way, on the one hand, the cooperation of the extrusion block 5 and the pressing rod 3 makes the simulated air pressure of the pressing mechanism on the nylon material decrease from the center to the edge, thereby further increasing the authenticity of the simulation and improving the accuracy of the hardness detection result. On the other hand, the spring 8 can provide a certain buffering effect, thereby avoiding the abrasion of the bottom end of the nylon material by the pressing top cover 6 and affecting the hardness detection result.

[0032] In the embodiment, the outer wall of the pressing lower rod 7 is fixedly installed with a limiting ring 9, and the limiting ring 9 abuts against the top end of the support guide frame 4. In this way, when no detection is performed, the limiting ring 9 abuts against the top end of the support guide frame 4, thereby fixing the position of the pressing lower rod 7 and preventing the pressing lower rod 7 from moving downward due to gravity, so that the pressing lower rod 7 drives the spring 8 to elastically deform, thereby keeping the spring 8 in a stretched deformation state for a long time and shortening the service life.

[0033] In the embodiment, the bottom end of the pressing lower rod 7 is configured as a spherical end 10. In this way, the contact area between the bottom end of the pressing lower rod 7 and the extrusion block 5 can be reduced, and the friction can be reduced, so that the pressing rod 3 can be more easily pushed. At the same time, the spherical end 10 helps the pressing rod 3 to self-align when it is pushed. Due to the geometric characteristics of the sphere, no matter which direction the force is applied to the spherical end 10, the spherical end 10 can automatically adjust to a balanced position, so that the pressing rod 3 can remain vertical or at a desired angle.

[0034] In the embodiment, as shown in Figure 4As shown, the lifting assembly comprises a sliding base 11 arranged at the bottom end of the extrusion block 5, both sides of the sliding base 11 are fixedly installed with sliding blocks 12, one side of the sliding block 12 is slidingly installed with a lifting block 13, the inner side of the lifting block 13 is threadedly installed with a lead screw 14, and the top end of the lead screw 14 is installed with a motor 15. In this way, when it is necessary to simulate the pressure on the nylon material, the motor 15 is started to drive the lead screw 14 to rotate, the lead screw 14 drives the lifting block 13 to move, the lifting block 13 drives the sliding block 12 and the sliding base 11 to move, and the sliding base 11 drives the extrusion block 5 to move. In addition, the extrusion block 5 is a spherical section block with a central protrusion in this embodiment, when the pressure simulation of other conditions is performed, the sliding base 11 can be pulled out of the lifting block 13 together with the sliding block 12 to replace the extrusion block 5.
