Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0022] Example 1: Please see Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a composite material compression test fixture, including: The mounting mechanism 100 includes a mounting base 101, a support column 102 fixed to one top end of the mounting base 101, a top seat 103 fixed to the top of the support column 102, positioning rods 104 fixed to the four corners of the top of the mounting base 101, a placement platform 105 fixed to the top of the mounting base 101, and a clamping assembly 106 installed in the placement platform 105. The testing mechanism 200 includes a lifting cylinder 201 fixed to the bottom of the top seat 103, a testing platform 202 installed at the bottom of the lifting cylinder 201, a testing component 203 fixed to the bottom of the testing platform 202, and a testing probe 204 installed on the support column 102 near the center of the mounting base 101.

[0023] Specifically, the clamping assembly 106 includes a placement groove 1061 opened inside the center of the top of the placement platform 105, clamping plates 1062 evenly distributed in the placement groove 1061, and limiting rods 1063 fixed to the four corners of the clamping plate 1062 on the side away from the center of the placement platform 105.

[0024] Specifically, the top of the clamping plate 1062 is curved on the side near the center, and the limiting rod 1063 is inserted into the interior of the placement platform 105.

[0025] Specifically, an adjustment block 1064 is fixed at the bottom center of the clamping plate 1062, an adjustment groove is opened in the placement platform 105, an adjustment screw 1065 is rotatably connected inside the adjustment groove, a rotating bevel gear 1066 is fixed to the side of the adjustment screw 1065 near the center of the placement platform 105, a linkage bevel gear 1067 is meshed with the bottom of the rotating bevel gear 1066, a rotating shaft is installed at the bottom center of the linkage bevel gear 1067, and a rotating motor 1068 is installed at the bottom of the rotating shaft.

[0026] Specifically, the adjusting screw 1065 forms a synchronous rotation structure through the rotating bevel gear 1066 and the linkage bevel gear 1067, the adjusting block 1064 and the clamping plate 1062 form an integrated structure, and the clamping plate 1062 forms a relative movement structure with the placement platform 105 through the adjusting screw 1065.

[0027] Furthermore, the composite material to be tested is placed inside the placement slot 1061. The lifting cylinder 201 is activated, which lowers the position of the testing platform 202. The pressure generated by the downward movement of the testing platform 202 completes the test of the composite material. The distance between the clamping plates 1062 is adjusted according to the size of the composite material to be tested. The rotating motor 1068 is activated, which drives the rotating shaft and the linkage bevel gear 1067 to rotate. Through the meshing structure, the rotating bevel gear 1066 is driven to rotate. The rotating bevel gear 1066 drives the adjusting screw 1065 to rotate synchronously. The adjusting screw 1065 drives the adjusting block 1064 to adjust the position, thereby adjusting the position of the clamping plate 1062 and clamping and fixing the composite material through the clamping plate 1062.

[0028] In use, the distance between the clamping plates 1062 is first adjusted according to the size and model of the composite material. Due to the threaded connection between the inner surface of the adjusting block 1064 and the outer surface of the adjusting screw 1065, the relative position of the adjusting blocks 1064 can be moved when the adjusting screw 1065 rotates. The position of the clamping plates 1062 is moved by the movement of the adjusting blocks 1064. This setting allows the position of the clamping plates 1062 to be adjusted according to the size and model of the composite material to be tested, so as to meet the clamping test of different models of composite materials and reduce the types and models of tooling required.

[0029] In summary, since different types of composite materials need to be tested, the position of the clamping plate 1062 needs to be adjusted accordingly based on the different sizes and types of composite materials to be tested. An adjustable clamping plate 1062 increases the number of application scenarios and the applicability of the material.

[0030] Example 2: Please see Figure 1 and Figure 5 This is the second embodiment of the present utility model.

[0031] Specifically, the detection component 203 includes a pressing head 2031 fixed to the bottom of the detection table 202, positioning heads 2032 evenly distributed at the bottom of the pressing head 2031, and anti-slip grooves 2033 formed in the positioning head 2032.

[0032] Specifically, the center of the pressing head 2031 and the center of the placement platform 105 are located on the same vertical line, and the positioning head 2032 is distributed in a ring with the center of the pressing head 2031 as the center.

[0033] Specifically, a control device 205 is mounted on the top of the top seat 103, a display 206 is fixed to one end of the top of the control device 205, and a control keyboard 207 is mounted on the other end of the top of the control device 205.

[0034] Furthermore, after the composite material is fixed, the lifting cylinder 201 is activated. The lifting cylinder 201 drives the test platform 202 and the pressure head 2031 to descend. The pressure generated when the pressure head 2031 descends completes the test on the composite material. During the test, the positioning head 2032 and the anti-slip groove 2033 work together to prevent the composite material from shifting due to the downward pressure during the test.

[0035] In use, the pressure generated when the pressure head 2031 moves downward is used to test the composite material. During the test, the positioning head 2032 and the anti-slip groove 2033 work together to prevent the composite material from shifting due to the downward pressure, thus ensuring the accuracy of the test results. During the test, the deformation of the composite material is monitored by the detection probe 204.

[0036] In summary, the pressure generated when the pressure head 2031 moves downward is used to complete the test of the composite material. During the test, the deformation of the composite material is monitored by the detection probe 204, and the test results of the composite material are monitored in real time by the control device 205 and the display 206, and the test results at different stages are recorded and analyzed.
