[0003] When measuring the rotation angle of a large number of specimens, the staff needs to repeatedly operate the compression shear tester. Specifically, two specimens are placed on both sides of the middle load beam of the compression shear tester, and the oil cylinder of the compression shear tester is controlled to load the axial load to the two specimens through the upper load plate and the lower load plate, and then the rotation angle of the specimen is measured. After the measurement is completed, the oil cylinder is unloaded, and the upper load plate and the lower load plate are reset. Then the two tested specimens are removed, two new specimens are reassembled, and the above steps are repeated.

[0010] Furthermore, the test plate has a specimen mounting area and a plurality of mounting holes; the plurality of mounting holes are arranged at equal intervals along the circumference of the specimen mounting area; the force transmission member includes a plurality of force transmission rods, the mounting holes are used for detachable connection with one end of the force transmission rod, and the other end of the force transmission rod is used to cooperate with the free end of the angle load cylinder.

[0011] Furthermore, in the test plate set, the number of force transmission rods is less than or equal to the number of mounting holes.

[0012] Furthermore, the force transmission rod is provided with a slot, and a part of the test plate is inserted into the slot; the force transmission member also includes a plurality of fasteners, each fastener cooperates with a force transmission rod, and the part of the force transmission rod provided with the slot and the mounting hole of the test plate are fastened and assembled by the fasteners.

[0013] Furthermore, the two loading platforms are respectively recorded as the first loading platform and the second loading platform; the driving structure includes a first oil cylinder and a second oil cylinder, the free end of the first oil cylinder is connected to the middle part of the first loading platform, and the free end of the second oil cylinder is connected to the middle part of the second loading platform, and the middle part of the first loading platform and the middle part of the second loading platform are arranged relatively.

[0017] The beneficial effects of the present invention are:

[0018] The compression shear testing machine rotation angle measurement support platform of the present invention comprises a support body, a driving structure, two loading platforms, a plurality of rotation angle load oil cylinders and a plurality of test plate groups.

[0019] The support body is provided with a test area, and when the angle of the specimen is measured, the specimen is located in the test area. The driving structure and multiple angle load cylinders are both provided on the support body, and the support body has the function of supporting and fixing the driving structure and multiple angle load cylinders, and can ensure the matching size of the test area with the driving structure and multiple angle load cylinders, and provide structural support for the angle measurement of the specimen.

[0020] Any of the multiple test plate groups includes a test plate and a force transmission member. The test plate is used to install and position the specimen. Each test plate group is used in conjunction with an angle load cylinder. Specifically, one end of the force transmission member is connected to the test plate, and the free end of the angle load cylinder is matched with the other end of the force transmission member.

[0021] When measuring the angle of the sample, the sample is placed on the test plate, and the driving structure controls the two loading platforms to work so as to apply a load force to the sample on the test plate along the height direction of the supporting body, so that the sample produces vertical compression deformation. At the same time, the angle load cylinder works, and the free end of the angle load cylinder cooperates with the other end of the force transmission member to drive the other end of the force transmission rod to move along the direction from the bottom to the top of the supporting body, that is, to lift the other end of the force transmission rod along the height direction of the supporting body. Since the test plate is connected to one end of the force transmission member, the test plate group can rotate under the action of the angle load cylinder, and the sample will produce angle deformation accordingly. The driving structure, the two loading platforms, the test plate group and the angle load cylinder cooperate to achieve the purpose of measuring the angle of the sample.

[0022] There are multiple corner load cylinders and multiple test plate groups, and each test plate group cooperates with a corner load cylinder. When a large number of specimens need to be tested, multiple specimens can be assembled on multiple test plate groups at the same time, and the driving structure cooperates with multiple corner load cylinders to measure the angles of a large number of specimens at the same time. When a small number of specimens need to be tested, specimens can be assembled on some of the test plate groups in the multiple test plate groups, and the driving structure cooperates with some of the corner load cylinders in the multiple corner load cylinders to measure the angles of a small number of specimens at the same time. In other words, the operation of the corner load cylinder and the driving structure can be controlled in a targeted manner according to the number of specific specimens to be tested to meet the diverse usage requirements of users, improve the adaptability of the angle measurement support platform of the compression and shear testing machine, and improve the performance of the angle measurement support platform of the compression and shear testing machine.

[0023] Multiple test plate groups are located between the two loading platforms, that is, multiple test plate groups share two loading platforms. When the two loading platforms apply load forces to multiple specimens at the same time, the vertical compression deformation of multiple specimens can be balanced, which is beneficial to improve the accuracy of the angle measurement of multiple specimens of the same type at the same time and reduce interference errors. At the same time, multiple test plate groups share two loading platforms, which saves installation space and reduces the difficulty of assembling the angle measurement support platform of the compression shear test machine compared to each test plate group being equipped with two separate loading platforms.

[0024] When the angle of the sample is measured, the torque generated by the angle test force will be transmitted to the load sensor and drive structure of the compression shear tester through the two loading platforms. When multiple sample plate groups of the present invention are assembled with multiple samples at the same time, multiple angle load cylinders apply equal forces to the test plate groups in the same direction, which is conducive to improving the balance and consistency of the forces at different positions of the two loading platforms, and is conducive to offsetting the torsional force and horizontal radial force on the load sensor and the drive structure, which can improve the detection accuracy of the load sensor, reduce the loss of the drive structure, and help extend the service life of the drive structure.

[0041] Refer to the following Figures 1 to 11 The following describes a support platform 10 for measuring the rotation angle of a compression shear tester according to some embodiments of the present invention.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, according to some embodiments of the present invention, a compression shear test machine angle measurement support platform 10 includes: a support body 100, the support body 100 is provided with a test area 110; a driving structure 200, which is arranged on the support body 100; two loading platforms 300, both of which are located in the test area 110, and the two loading platforms 300 are arranged opposite to each other and at intervals along the height direction of the support body 100; a plurality of angle load cylinders 400, which are arranged on the support body 100, and the plurality of angle load cylinders 400 are arranged at intervals along the circumference of the test area 110; a plurality of test plate groups 500, and a plurality of test plate groups 500 are arranged at intervals along the circumference of the test area 110; and a plurality of test plate groups 500 are arranged at intervals along the circumference of the test area 110. 500 are located between two loading platforms 300, each test plate group 500 includes a test plate 510 and a force transmission member 520, the test plate 510 is used for installing and positioning the sample 20, one end of the force transmission member 520 is connected to the test plate 510, the free end of each corner load cylinder 400 cooperates with the other end of the force transmission member 520 of a test plate group 500, the corner load cylinder 400 is used to drive the other end of the force transmission member 520 to move along the height direction of the support body 100, and the driving structure 200 is used to drive the two loading platforms 300 to apply load force to the sample 20 in the height direction of the support body 100.

[0043] In this embodiment, the compression shear testing machine rotation angle measurement support platform 10 includes a support body 100 , a driving structure 200 , two loading platforms 300 , a plurality of rotation angle load cylinders 400 and a plurality of test plate groups 500 .

[0044] The support body 100 is provided with a test area 110. When the rotation angle of the sample 20 is measured, the sample 20 is located in the test area 110. The driving structure 200 and the multiple rotation angle load cylinders 400 are both provided on the support body 100. The support body 100 has the function of supporting and fixing the driving structure 200 and the multiple rotation angle load cylinders 400, and can ensure the matching size of the test area 110 and the driving structure 200 and the multiple rotation angle load cylinders 400, so as to provide structural support for the rotation angle measurement of the sample 20.

[0045] Any of the plurality of test plate groups 500 includes a test plate 510 and a force transmission member 520. The test plate 510 is used to install and position the test specimen 20. Each test plate group 500 is used in conjunction with a corner load cylinder 400. Specifically, one end of the force transmission member 520 is connected to the test plate 510, and the free end of the corner load cylinder 400 is matched with the other end of the force transmission member 520.

[0046] When measuring the rotation angle of the sample 20, the sample 20 is placed on the test plate 510, and the driving structure 200 controls the two loading platforms 300 to work, so as to apply a load force to the sample 20 on the test plate 510 along the height direction of the support body 100, so that the sample 20 produces a vertical compression deformation. At the same time, the corner load cylinder 400 works, and the free end of the corner load cylinder 400 cooperates with the other end of the force transmission member 520 to drive the other end of the force transmission rod 522 to move along the direction from the bottom to the top of the support body 100, that is, to lift the other end of the force transmission rod 522 along the height direction of the support body 100. Since the test plate 510 is connected to one end of the force transmission member 520, the test plate group 500 can rotate under the action of the corner load cylinder 400, and the sample 20 produces a corner deformation accordingly. The driving structure 200, the two loading platforms 300, the test plate group 500 and the corner load cylinder 400 cooperate to achieve the purpose of measuring the rotation angle of the sample 20.

[0047] There are multiple corner load cylinders 400, and there are multiple test plate groups 500, and each test plate group 500 cooperates with a corner load cylinder 400. When a large number of specimens 20 need to be tested, multiple specimens 20 can be assembled on multiple test plate groups 500 at the same time, and the driving structure 200 cooperates with multiple corner load cylinders 400, so that the angle measurement of a large number of specimens 20 can be performed at the same time. When a small number of specimens 20 need to be tested, the specimens 20 can be assembled on a part of the test plate groups 500 in the multiple test plate groups 500, and the driving structure 200 cooperates with a part of the corner load cylinders 400 in the multiple corner load cylinders 400, so that the angle measurement of a small number of specimens 20 can be performed at the same time. In other words, the operation of the corner load cylinder 400 and the driving structure 200 can be controlled in a targeted manner according to the number of specific specimens 20 to be tested, so as to meet the diverse use needs of users, improve the use adaptability of the corner measurement support platform 10 of the compression shear test machine, and improve the use performance of the corner measurement support platform 10 of the compression shear test machine.

[0048] The multiple test plate groups 500 are all located between the two loading platforms 300, that is, the multiple test plate groups 500 share two loading platforms 300. When the two loading platforms 300 simultaneously apply load forces to the multiple specimens 20, the vertical compression deformation of the multiple specimens 20 can be balanced, which is beneficial to improve the accuracy of the angle measurement of multiple specimens of the same type at the same time and reduce interference errors. At the same time, the multiple test plate groups 500 share two loading platforms 300, which has the advantages of saving installation space and reducing the difficulty of assembling the angle measurement support platform 10 of the compression shear test machine, compared with each test plate group being equipped with two separate loading platforms.

[0049] When the angle of the sample 20 is measured, the torque generated by the angle test force will be transmitted to the load sensor and the drive structure 200 of the compression shear tester through the two loading platforms 300. When the multiple test plate groups 500 of the present invention are equipped with multiple samples 20 at the same time, the multiple angle load cylinders 400 apply equal forces to the test plate groups 500 in the same direction, which is conducive to improving the balance and consistency of the forces at different positions of the two loading platforms 300, and is conducive to offsetting the torsional force and horizontal radial force on the load sensor and the drive structure 200, which can improve the detection accuracy of the load sensor, reduce the loss of the drive structure 200, and help extend the service life of the drive structure 200.

[0050] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, along the height direction of the support body 100, the test plate 510 has a first end face 512 and a second end face 514, the first end face 512 and a loading platform 300 enclose a first installation area 600, and the second end face 514 and another loading platform 300 enclose a second installation area 700, and both the first installation area 600 and the second installation area 700 are used to accommodate the sample 20.

[0051] In this embodiment, the matching structure of the test plate 510 and the two loading platforms 300 is further defined.

[0052] The test plate 510 has a first end surface 512 and a second end surface 514 , and the first end surface 512 and the second end surface 514 are arranged along the height direction of the support body 100 .

[0053] The first end surface 512 is disposed opposite to one loading platform 300 , and the second end surface 514 is disposed opposite to another loading platform 300 .

[0054] Specifically, the first end surface 512 and one loading platform 300 enclose a first installation area 600 , and the second end surface 514 and another loading platform 300 enclose a second installation area 700 .

[0055] When measuring the rotation angle of the sample 20, one sample 20 is placed on the first end surface 512 of the test plate 510, and the other sample 20 is placed on the second end surface 514 of the test plate 510. The two loading platforms 300 are controlled by the driving structure 200 to apply load force to the two samples 20 on the test plate 510 along the height direction of the support body 100.

[0056] In some embodiments, Figure 5 , Figure 7 , Figure 8 and Fig. 9As shown, the middle parts 310 of the two loading platforms 300 are arranged opposite to each other; a plurality of test plate groups 500 are arranged at equal intervals around the middle part 310 of the loading platform 300; and a plurality of corner load cylinders 400 are arranged at equal intervals around the middle part 310 of the loading platform 300.

[0057] In this embodiment, the cooperation structure of two loading platforms 300 , a plurality of test plates 510 , and a plurality of corner load cylinders 400 is further defined.

[0058] The middle parts 310 of the two loading platforms 300 are arranged opposite to each other, a plurality of test plate groups 500 are arranged at equal intervals around the middle part 310 of the loading platforms 300 , and a plurality of corner load cylinders 400 are arranged at equal intervals around the middle part 310 of the loading platforms 300 .

[0059] This arrangement balances the arrangement positions of the multiple test plate groups 500 and the multiple corner load cylinders 400, so that the multiple test plate groups 500 are arranged at equal intervals around the middle 310 of the loading platform 300, and the multiple corner load cylinders 400 are arranged at equal intervals around the middle 310 of the loading platform 300. When the multiple test plate groups 500 are simultaneously equipped with multiple specimens 20, the multiple corner load cylinders 400 apply equal forces to the test plate groups 500 in the same direction, which can effectively improve the balance and consistency of the forces at different positions of the two loading platforms 300, and can effectively offset the torsional force and horizontal radial force on the load sensor and the drive structure 200, which is beneficial to improving the detection accuracy of the load sensor, reducing the loss of the drive structure 200, and extending the service life of the drive structure 200.

[0060] Specifically, the first section is obtained by sectioning the compression shear test machine rotation angle measurement support platform 10 along the height direction perpendicular to the support body 100. In the first section, the centers of the multiple test plates 510 are in a circle, which is recorded as the first circle. When the number of the test plate group 500 is greater than or equal to three, in the first section, the line connecting the centers of two adjacent test plates 510 is recorded as the first line, and the lengths of any two first lines are equal.

[0061] Specifically, the second section is obtained by cutting the compression shear test machine corner measurement support platform 10 in a height direction perpendicular to the support body 100. In the second section, the axes of the plurality of corner load cylinders 400 are in a circle, which is recorded as the second circle. When the number of the corner load cylinders 400 is greater than or equal to three, in the second section, the line connecting the axes of two adjacent corner load cylinders 400 is recorded as the second line, and the lengths of any two second lines are equal.

[0062] Specifically, along the height direction of the support body 100 , the projection of the center of the first circle in the second cross section coincides with the center of the second circle.

[0063] In some embodiments, Figure 1, Figure 2 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the test plate 510 has a sample installation area 516 and a plurality of installation holes 518; the plurality of installation holes 518 are arranged at equal intervals along the circumference of the sample installation area 516; the force transmission member 520 includes a plurality of force transmission rods 522, the installation holes 518 are used for detachable connection with one end of the force transmission rod 522, and the other end of the force transmission rod 522 is used to cooperate with the free end of the corner load cylinder 400.

[0064] In this embodiment, the matching structure of the test plate 510 and the force transmission member 520 is further defined.

[0065] The test plate 510 has a sample installation area 516, which is used to install and fix the sample 20. The test plate 510 also has a plurality of installation holes 518, which are arranged at equal intervals along the circumference of the sample installation area 516. Specifically, along the height direction of the support body 100, the test plate 510 has a first end surface 512 and a second end surface 514, the first end surface 512 is formed with the sample installation area 516, and the second end surface 514 is also formed with the sample installation area 516. Each installation hole 518 runs through the first end surface 512 and the second end surface 514.

[0066] The force transmission member 520 includes a plurality of force transmission rods 522, and the mounting hole 518 is used to be detachably connected to one end of the force transmission rod 522. That is, according to specific actual measurement needs, one of the plurality of mounting holes 518 can be assembled with the force transmission rod 522. When the test plate group 500 and the corner load cylinder 400 are assembled, one end of the force transmission rod 522 is detachably connected to the mounting hole 518, and the other end of the force transmission rod 522 cooperates with the free end of the corner load cylinder 400. The telescopic free end of the corner load cylinder 400 can drive the other end of the force transmission rod 522 to move in the height direction of the support body 100, thereby achieving the purpose of the test plate group 500 rotating under the action of the corner load cylinder 400.

[0067] It can be understood that the force transmission rod 522 is used to connect the mounting hole 518 and the free end of the corner load cylinder 400. The plurality of mounting holes 518 are arranged at equal intervals along the circumference of the specimen mounting area 516, and the distances from the plurality of mounting holes 518 to the free end of the corner load cylinder 400 are not exactly the same. In this way, it is necessary to match the force transmission rods 522 of corresponding lengths. In other words, at least a portion of the plurality of force transmission rods 522 are of unequal lengths. For example, the number of the mounting holes 518 is three, and the three mounting holes 518 are respectively recorded as the first hole, the second hole, and the third hole. The number of the force transmission rods 522 is three, and the three force transmission rods 522 are respectively recorded as the first rod, the second rod, and the third rod. The first rod is used to connect the first hole and the free end of the corner load cylinder 400, the second rod is used to connect the second hole and the free end of the corner load cylinder 400, and the third rod is used to connect the third hole and the free end of the corner load cylinder 400. The distances from the center of the first hole and the second hole to the free end of the corner load cylinder 400 are both L1, and the distance from the center of the third hole to the free end of the corner load cylinder 400 is L2, and L2 is smaller than L1. That is, the lengths of the first rod and the second rod are equal, and the lengths of the first rod and the second rod are both greater than the length of the third rod. When it is necessary to measure the specimen 20 in the first direction, the first hole and the free end of the corner load cylinder 400 can be connected by the first rod, or the second hole and the free end of the corner load cylinder 400 can be connected by the second rod. When it is necessary to measure the specimen 20 in the second direction, the third hole and the free end of the corner load cylinder 400 can be connected by the third rod. In which, during a single measurement, only one force transmission rod 522 needs to be assembled.

[0068] The plurality of mounting holes 518 are arranged at equal intervals along the circumference of the sample mounting area 516, that is, the plurality of mounting holes 518 are all located outside the sample mounting area 516. The first end face 512 of the test plate 510 and a loading platform 300 enclose a first mounting area 600 for accommodating the sample 20, and the second end face 514 and another loading platform 300 enclose a second mounting area 700 for accommodating the sample 20. There is a gap between the other end of the force transmission rod 522 and the two loading platforms 300, and the thickness of the sample 20 provides a disassembly space for disassembling the force transmission rod 522. Among them, the volume of the sample 20 is relatively large, and the volume of the sample 20 is related to the size of the loading platform 300, which can provide a sufficiently large reserved space for disassembling the force transmission rod 522. In addition, the sample 20 is elastic, and after the measurement of the sample 20 in the first direction is completed, the sample 20 can be reset to the original shape, which will not affect the normal installation of the force transmission rod 522 next time.

[0069] In this way, during the process of measuring the rotation angle of the sample 20, the sample 20 can be measured in multiple directions, that is, without changing the existing installation position of the sample 20 (that is, without changing the loading state of the driving structure 200), by controlling the working state of multiple rotation angle load cylinders 400 and disassembling and assembling the corresponding force transmission rods 522, the force angle and force position of the sample 20 can be converted. This setting simplifies the operational difficulty of measuring the sample 20 and can reduce the energy consumption of re-unloading and re-loading.

[0070] In some embodiments, in the test plate set 500 , the number of force transmission rods 522 is less than or equal to the number of mounting holes 518 .

[0071] In this embodiment, the structure of the test board set 500 is further defined.

[0072] The test plate 510 is provided with a plurality of mounting holes 518, and the force transmission member 520 includes a plurality of force transmission rods 522. The number of force transmission rods 522 is less than or equal to the number of mounting holes 518, that is, the number of force transmission rods 522 is equal to the number of mounting holes 518, or the number of force transmission rods 522 is less than the number of mounting holes 518.

[0073] When the number of force transmission rods 522 is equal to the number of mounting holes 518 , each mounting hole 518 is correspondingly equipped with an exclusive force transmission rod 522 .

[0074] When the number of force transmission rods 522 is less than the number of mounting holes 518, a portion of mounting holes 518 are equipped with a dedicated force transmission rod 522, and the other portion of mounting holes 518 share the same force transmission rod 522. This arrangement reduces the number of force transmission rods 522 and the material input of the force transmission member 520 while meeting the use requirements of measuring the rotation angle of the specimen 20, which is beneficial to reducing the number of accessories of the compression shear test machine rotation angle measurement support platform 10 and reducing the production cost of the compression shear test machine rotation angle measurement support platform 10.

[0075] Specifically, Figure 7 , Figure 8 and Fig. 9 As shown, the number of the test plate group 500 and the number of the corner load cylinder 400 are both three. Each test plate 510 is provided with three mounting holes 518. The force transmission member 520 of each test plate group 500 includes two force transmission rods 522, and the lengths of the two force transmission rods 522 are different. The two force transmission rods 522 are respectively denoted as the first force transmission rod 522a and the second force transmission rod 522b. The three corner load cylinders 400 are respectively marked with c, d and e. Fig.10 and Fig.11As shown, the three mounting holes 518 on the first test board 510 are marked with 1, 2 and 3 respectively, the three mounting holes 518 on the second test board 510 are marked with 4, 5 and 6 respectively, and the three mounting holes 518 on the third test board 510 are marked with 7, 8 and 9 respectively. Fig.10 and Fig.11 As shown, the position of the corner load cylinder 400 is different, and the length of the force transmission rod 522 matched with the corner load cylinder 400 also changes accordingly.

[0076] In the first section, the centers of the sample installation areas 516 of the three test boards 510 are in a circle, which is recorded as the first circle. In the first section, the line connecting the centers of the sample installation areas 516 of two adjacent test boards 510 is recorded as the first connecting line, and the lengths of any two first connecting lines are equal.

[0077] In the second section, the axes of the three corner load cylinders 400 are in a circle, which is recorded as the second circle. In the second section, the line connecting the axes of two adjacent corner load cylinders 400 is recorded as the second line, and the lengths of any two second lines are equal.

[0078] Along the height direction of the support body 100 , the projection of the center of the first circle in the second cross section coincides with the center of the second circle.

[0079] in, Figure 7 The force transmission rod 522 in the embodiment is a first force transmission rod 522a. Figure 8 and Fig. 9 The force transmission rod 522 in the figure is the second force transmission rod 522b. For a single measurement, only the first force transmission rod 522a or the second force transmission rod 522b needs to be installed.

[0080] In some embodiments, Figure 1 and Figure 2 As shown, the force transmission rod 522 is provided with a slot 5222, and a portion of the test plate 510 is inserted into the slot 5222; the force transmission member 520 also includes a plurality of fasteners 524, each fastener 524 cooperates with a force transmission rod 522, and the portion of the force transmission rod 522 provided with the slot 5222 and the mounting hole 518 of the test plate 510 are fastened and assembled through the fasteners 524.

[0081] In this embodiment, the structure of the force transmission member 520 is further defined.

[0082] The force transmission member 520 further includes a plurality of fasteners 524. Each fastener 524 cooperates with a force transmission rod 522. Specifically, the fastener 524 includes a bolt and a nut. Specifically, the force transmission rod 522 is provided with a slot 5222, and a portion of the test plate 510 is inserted into the slot 5222. That is, the force transmission rod 522 is plug-fitted with the test plate 510. The portion of the force transmission rod 522 provided with the slot 5222 and the mounting hole 518 of the test plate 510 are fastened and assembled by the fastener 524, and this arrangement can meet the use requirements of the force transmission rod 522 and the test plate 510 being detachably connected.

[0083] In some embodiments, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the two loading platforms 300 are respectively recorded as the first loading platform 300a and the second loading platform 300b; the driving structure 200 includes a first cylinder 210 and a second cylinder 220, the free end of the first cylinder 210 is connected to the middle of the first loading platform 300a, and the free end of the second cylinder 220 is connected to the middle of the second loading platform 300b, and the middle of the first loading platform 300a and the middle of the second loading platform 300b are relatively arranged.

[0084] In this embodiment, the matching structure of the two loading platforms 300 and the driving structure 200 is further defined.

[0085] The two loading platforms 300 are respectively referred to as a first loading platform 300 a and a second loading platform 300 b , and the test plate set 500 is located between the first loading platform 300 a and the second loading platform 300 b .

[0086] The driving structure 200 includes a first oil cylinder 210 and a second oil cylinder 220. The free end of the first oil cylinder 210 is connected to the middle of the first loading platform 300a, and the free end of the second oil cylinder 220 is connected to the middle of the second loading platform 300b. The first oil cylinder 210 can apply a load force to the sample 20 in the height direction of the support body 100 through the first loading platform 300a. The second oil cylinder 220 can apply a load force to the sample 20 in the height direction of the support body 100 through the second loading platform 300b.

[0087] In addition, the middle of the first loading platform 300a and the middle of the second loading platform 300b are arranged opposite to each other, so that the driving structure 200 can ensure the balance and consistency of the vertical load force applied to the multiple samples 20 through the first loading platform 300a and the second loading platform 300b. The balance of the vertical compression deformation of the multiple samples 20 can be ensured, which is beneficial to improve the accuracy of the simultaneous angle measurement of multiple samples of the same type and reduce interference errors.

[0088] In some embodiments, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the support body 100 includes: a seat body 120, a plurality of corner load cylinders 400 and a second cylinder 220 are all connected to the seat body 120; a frame 130, which is arranged above the seat body 120; a mounting member 140, which is arranged on the frame 130, and a test area 110 is enclosed between the mounting member 140, the frame 130 and the seat body 120, and the first cylinder 210 is arranged on the side of the mounting member 140 facing the seat body 120.

[0089] In this embodiment, the structure of the support body 100 is further defined.

[0090] The supporting body 100 includes a base 120 , a frame 130 and a mounting member 140 .

[0091] The frame 130 is disposed above the base 120, the mounting member 140 is disposed on the frame 130, the first oil cylinder 210 is disposed on the side of the mounting member 140 facing the base 120, and the plurality of corner load oil cylinders 400 and the second oil cylinder 220 are connected to the base 120. That is, the frame 130 cooperates with the base 120 to play the role of installing and fixing the plurality of corner load oil cylinders 400, the second oil cylinder 220, the mounting member 140 and the first oil cylinder 210. The positional relationship between the test area 110, the first loading platform 300a and the second loading platform 300b can be ensured, and structural support is provided for the subsequent effective assembly of the plurality of test panel groups 500.

[0092] In some embodiments, Figure 5 As shown, multiple corner load cylinders 400 are connected to the outer wall of the seat body 120; the seat body 120 is provided with a mounting groove 122, the groove opening of the mounting groove 122 faces the mounting member 140, the second cylinder 220 is provided in the mounting groove 122, and the free end of the second cylinder 220 is connected to the second loading platform 300b through the groove opening of the mounting groove 122.

[0093] In this embodiment, the structure of the seat body 120 is further defined.

[0094] The seat body 120 is provided with a mounting groove 122, and the notch of the mounting groove 122 faces the mounting member 140. The second oil cylinder 220 is provided in the mounting groove 122. The mounting groove 122 has the function of mounting and fixing the second oil cylinder 220. At the same time, the seat body 120 can also play a role in protecting the second oil cylinder 220, preventing the external force from directly acting on the second oil cylinder 220, and can reduce the probability of the second oil cylinder 220 being damaged by the external force, which is conducive to extending the service life of the angle measurement support platform 10 of the compression shear test machine.

[0095] The notch of the mounting groove 122 faces the mounting member 140, the second loading platform 300b is arranged opposite to the notch of the mounting groove 122, and the free end of the second oil cylinder 220 is connected to the second loading platform 300b through the notch of the mounting groove 122. That is, the notch of the mounting groove 122 has the function of connecting the free end of the second oil cylinder 220 with the second loading platform 300b, so that the second oil cylinder 220 can effectively drive the second loading platform 300b to move.

[0096] In some embodiments, Figure 3 As shown, the length of the seat body 120 in the first direction is greater than the length of the seat body 120 in the second direction; along the first direction, the outer peripheral wall of the seat body 120 includes two mounting surfaces 124, and at least one of the two mounting surfaces 124 is provided with a groove 126; when the corner load cylinder 400 is located on one side of the mounting surface 124 provided with the groove 126, the corner load cylinder 400 is connected to the groove 126.

[0097] In this embodiment, the matching structure between the seat body 120 and the angle load cylinder 400 is further defined.

[0098] The length of the base body 120 in the first direction is greater than the length of the base body 120 in the second direction. For example, the base body 120 is a rectangular structure.

[0099] Along the first direction, the outer peripheral wall of the seat body 120 includes two mounting surfaces 124. At least one of the two mounting surfaces 124 is provided with a groove 126, that is, one mounting surface 124 is provided with a groove 126, or both mounting surfaces 124 are provided with a groove 126.

[0100] The two mounting surfaces 124 are respectively referred to as the first mounting surface and the second mounting surface. When the first mounting surface is provided with a groove 126 and the corner load cylinder 400 is located on one side of the first mounting surface, the corner load cylinder 400 is connected to the groove 126. When the second mounting surface is provided with a groove 126 and the corner load cylinder 400 is located on one side of the second mounting surface, the corner load cylinder 400 is connected to the groove 126.

[0101] That is, the groove 126 has the function of accommodating the corner load cylinder 400. In this way, while ensuring the effective assembly of the seat body 120 and the corner load cylinder 400, the assembly dimensions of the seat body 120 and the corner load cylinder 400 can be reduced along the first direction.

[0102] Optionally, the mounting member 140 is fixed to the frame 130. A first oil cylinder 210 is fixed below the mounting member 140. The free end of the first oil cylinder 210 is fixedly connected to the first loading platform 300a. The second oil cylinder 220 is fixed to the seat 120. The free end of the second oil cylinder 220 is fixedly connected to the second loading platform 300b. The corner load oil cylinder 400 is fixed to the seat 120.

[0103] Take the first force transmission rod 522a as an example. First, Figure 7 As shown, the first force transmission rod 522a is fixed to the test plate 510 by the fastener 524. Then, the first oil cylinder 210 and the second oil cylinder 220 are started, so that the first loading platform 300a and the second loading platform 300b apply vertical load forces to the three groups of specimens 20, each group of specimens 20 includes two specimens 20. Then, the three corner load oil cylinders 400 are started, and the first force transmission rod 522a is supported by the free end of the corner load oil cylinder 400, thereby causing the test plate 510 to deflect, so that the corner performance of the specimens 20 can be measured.

[0104] For example, if Figure 8 and Fig. 9 As shown, when it is necessary to measure the rotation angle at another angle, there is no need to change the working state of the first oil cylinder 210 and the second oil cylinder 220, and the positions of the first loading platform 300a and the second loading platform 300b remain unchanged. Remove the fasteners connecting the three first force transmission rods 522a, and remove the three first force transmission rods 522a. Connect the three second force transmission rods 522b at other positions of the test plate 510. Then, the rotation angle performance of the sample 20 can be measured.

[0105] In the related technology, the compression shear tester can only measure the specimen in one direction. If the direction needs to be changed, it is necessary to control the two cylinders to unload the axial load at the same time. At the same time, it is necessary to rotate the specimen to the corresponding position, and then re-control the two cylinders to load the axial load, and then the rotation angle of the specimen can be measured.

[0106] Compared with the compression shear tester of the related art, the present invention reduces the process of unloading and loading the first oil cylinder 210 and the second oil cylinder 220, and also reduces the process of rotating the sample 20, thus simplifying the operational difficulty of measuring the sample 20. In addition, the energy consumption is relatively large when unloading and loading the first oil cylinder 210 and the second oil cylinder 220, and reducing the process of unloading and loading the first oil cylinder 210 and the second oil cylinder 220 can reduce the energy consumption of the compression shear tester angle measurement support platform 10 of the present invention, and improve the performance of the compression shear tester angle measurement support platform 10.

[0107] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0108] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
