On the front and back sides of the support frame (2), sliding holes (15) are respectively opened. The support frame (2) penetrates and is slidably connected in the two sliding holes (15).

8. A method for using a diaphragm spring load detection device, according to any one of claims 1 to 7, characterized in that: The usage method includes the following steps: When performing a load test on the diaphragm spring, place the diaphragm spring to be tested on the test seat (6) on the second workbench (5). When limiting the diaphragm spring, lift the handle (906) to make it drive the clamping rod (903) to move upward, so that the clamping rod (903) disengages from the clamping slot (8) in the sliding groove (7), and its locking state on the slider (901) is released. By pushing the handle (906), it drives the slider (901) to move in the sliding groove (7) through the clamping rod (903) until the displacement sensor (907) outside the clamping rod (903) contacts the outer wall of the diaphragm spring. After releasing the handle (906), the sliding ring (904) is supported by the elastic force of the first spring (905). When the sliding ring (904) slides in the groove (902), it drives the clamping rod (903) to move downward, so that the bottom end of the clamping rod (903) is inserted into one of the clamping slots (8) to achieve the purpose of locking the slider (901). Similarly, operate other handles (906) to adjust the position of the slider (901) so that all three displacement sensors (907) contact the outer wall of the diaphragm spring, playing a role in limiting the diaphragm spring. By independently adjusting the positions of multiple sliders (901) and displacement sensors (907), it is convenient to limit diaphragm springs of different specifications; After the diaphragm spring is limited, the motor (111) is controlled to work so that it drives the driven gear (113) to rotate through the driving gear (112). The driving gear (112) and the driven gear (113) respectively drive the two studs (114) to rotate. During the rotation process, the lower stud (114) drives the workbench 2 (5) to move to the left through the second nut (12), so that the workbench 2 (5) drives the upper detection seat (6) and the diaphragm spring to move to the left and approach the detection component (3). During the rotation process, the upper stud (114) drives the slide (101) to move to the right through the first nut (105), so that the slide (101) drives the workbench through the two connecting plates (102). One (4) moves to the right, and the connecting plate (102) drives the bottom roller (103) to move to the highest point on the support bar (13). When the roller (103) moves to the lowest point of the support bar (13), the tension of multiple second springs (104) pulls the workbench one (4), so that the workbench one (4) moves down in the support frame (2), so that the workbench one (4) and the workbench two (5) are staggered during the relative movement. When the workbench two (5) drives the upper diaphragm spring to move into the detection component (3), the roller moves from the lowest point of the support bar (13) to the highest point on the right, so that the roller (103) pushes the workbench one (4) upward through the connecting plate (102); Secondly, the two electric hydraulic rods (302) in the detection component (3) are extended to drive the power sensor (303) to move downward, and the force sensor (303) drives the two pressure heads (304) to move downward and contact the top of the diaphragm spring. The force sensor (303) will measure the load borne by the diaphragm spring in real time. When the diaphragm spring is deformed by pressure, the displacement sensor (907) measures the deformation of the diaphragm spring under the load, which is conducive to analyzing the mechanical properties of the diaphragm spring. During the detection process, the diaphragm spring to be detected is placed in the detection seat (6) on the workbench (4) to complete the detection. After the inspection of the diaphragm spring on the second workbench (5) and the limiting of the diaphragm spring on the first workbench (4), the two electric hydraulic rods (302) are contracted to move the two pressure heads (304) away from the diaphragm spring, and the motor (111) is controlled to reverse, so that the driving gear (112) and the driven gear (113) respectively drive the two studs (114) to reverse. Similarly, the first workbench (4) and the second workbench (5) are moved relative to each other again and staggered. While the diaphragm spring on the first workbench (4) is unloaded, the inspection component (3) inspects the diaphragm spring on the second workbench (5).
