Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electrical cabinets, and specifically relates to a compression resistance testing device for electrical cabinet production. BACKGROUND

[0002] In the mass production process of electrical cabinets, accurate detection of the compression resistance performance thereof is a key link for guaranteeing product quality and safety. With the rapid development of the electric power industry, the application scenarios of electrical cabinets are increasingly complex and diverse, and the external pressure environments thereof are also different, so it is necessary to test the compression resistance of the cabinet body during production.

[0003] According to the compression resistance testing device for power distribution cabinet production disclosed in the patent with the publication number CN222353644U, the device comprises a compression resistance testing assembly, which is vertically fixedly installed on a support plate at the top of a detection box and is used for testing the compression resistance of the power distribution cabinet in the vertical direction, and two horizontal testing mechanisms are installed on the two sides of the detection box in parallel and correspondingly, and are used for clamping and fixing the power distribution cabinet and testing the compression resistance of the power distribution cabinet in the horizontal direction. The vertical testing mechanism on the compression resistance testing assembly is used for testing the compression resistance of the power distribution cabinet in the vertical direction, and the two horizontal testing mechanisms on the compression resistance testing assembly are used for clamping and fixing the power distribution cabinet during the vertical compression resistance test, and the horizontal testing mechanisms are used for testing the compression resistance of the power distribution cabinet in the horizontal direction, thereby improving the compression resistance test efficiency of the compression resistance testing device for the power distribution cabinet.

[0004] However, in actual work, the device has some problems. When the rotating drive part on the rotating assembly is started to drive the power distribution cabinet placed on the rotating table to rotate, the horizontal testing mechanisms originally used for clamping and fixing on the two sides will gradually move away from the surface of the cabinet body due to rotation. At this time, the cabinet body will generate a centrifugal force during rotation, and due to the lack of effective constraints, the centrifugal force will cause the position of the cabinet body to deviate. The deviation of the position of the cabinet body will directly cause the key parameters such as the point of force and the direction of force to change during the test, thereby making the test data unable to accurately reflect the real compression resistance of the power distribution cabinet, and greatly reducing the accuracy of the test data.

[0027] With the above scheme: by adjusting the design of the mechanism 5, the driving motor three 505 makes the gear four 506 rotate, because the gear four 506 is engaged with the gear three 504, and then the rotating gear four 506 will drive the gear three 504 to rotate, because the gear three 504 is screwed with the threaded rod 503, and then when the gear three 504 rotates, the threaded rod 503 will move inside the gear three 504, the connecting plate 501 will be driven to move, and the test assembly 4 will be driven to move, and then the test assembly 4 can be moved to a position suitable for the height of the cabinet, and then the test assembly 4 can be driven to test the cabinet, and finally the threaded rod 503 is adjusted by the driving motor three 505 to adjust the position of the test assembly 4, and then the cabinet of different heights can be tested, and the applicability of the equipment is improved.

[0028] As shown in Figure 5 The plug-in assembly 6 includes a fixed slot 601 opened on the surface of the sliding block 205 and the positioning plate 206, and the plug-in plate 602 is inserted into the fixed slot 601.

[0029] With the above scheme: through the design of the plug-in assembly 6, the plug-in plate 602 can be taken out from the inside of the fixed slot 601, and then the position of the positioning plate 206 can be adjusted to adapt to electrical cabinets of different widths, and then the plug-in plate 602 can be inserted into the fixed slot 601 again to fix the positioning plate 206.

[0030] As shown in Figure 6 It also includes: The rolling assembly 7 is arranged on the surface of the sliding block 205, and the rolling assembly 7 includes a support ring 701 slidingly sleeved on the surface of the sliding block 205, and the support ring 701 is fixedly connected with the workbench 201.

[0032] As shown in Figure 7 and Figure 8 It also includes: The limiting assembly 8 is arranged at the top end of the base 1, and the limiting assembly 8 includes a square shell 801 fixedly connected to the top end of the base 1, and a sliding shell 802 slidingly connected inside the square shell 801, and the top end of the sliding shell 802 is fixedly connected with the connecting plate 501.

[0035] With the above scheme: through the design of the protective pad 9, since the protective pad 9 is made of rubber material, when the suction cup 303 is adsorbed and fixed to the cabinet, the protective pad 9 will naturally deform according to the pressure between the cabinet and the fixing component, and the deformation of the protective pad 9 creates a space, so that the positioning plate 206 is not hindered when pushing the cabinet to move, ensuring the smooth adjustment of the position of the cabinet. At the same time, the circular hole formed in the middle of the protective pad 9 provides a passage for the adsorption of the suction cup 303, without affecting its fixing effect.

[0037] With the above scheme: through the design of the sliding shell 802, since the surface of the bottom end of the sliding shell 802 is provided with a square hole, the sliding shell 802 will not interfere with the movement of the sliding block 205, ensuring that the sliding block 205 and the positioning plate 206 can position the cabinet of different sizes. Through the design of the connecting block 203, since the surface of the connecting block 203 is smooth, it can move more smoothly inside the sliding ring 204. Moreover, the bottom end of the connecting block 203 is provided with a baffle, thereby ensuring that the sliding ring 204 will not move away from the surface of the connecting block 203, ensuring the stability of the operation of the components.

[0038] The working principle and use process of the present application are as follows: Firstly, the operator drives the motor three 505 to rotate the gear four 506, which drives the gear three 504 to rotate. When the gear three 504 rotates, the threaded rod 503 moves inside the gear three 504, which drives the connecting plate 501 to move, and the connecting plate 501 drives the test assembly 4 to move, thereby moving the test assembly 4 to a position suitable for the height of the electrical cabinet. Then, the electrical cabinet to be tested can be placed on the top end of the workbench 201, and then the driving motor 207 is driven to rotate the gear two 208, which drives the four gear one 202 and the connecting block 203 to rotate, the connecting block 203 slides inside the sliding ring 204, and in the process of sliding, it pushes the sliding ring 204, the sliding block 205 and the positioning plate 206 to move to the surface of the electrical cabinet, the moving positioning plate 206 pushes the electrical cabinet to move to the middle of the workbench 201, and when the four positioning plates 206 are in contact with the surface of the electrical cabinet at the same time, the positioning is completed; At the same time, when the gear one 202 drives the sliding block 205 to move, the sliding rod 302 is driven to move, and the sliding rod 302 slides inside the connecting cylinder 301, with the movement of the sliding rod 302, the air inside the connecting cylinder 301, the connecting pipe 304 and the suction cup 303 is extracted, and the suction cup 303 enters a negative pressure state, thereby adsorbing and fixing the cabinet body, after the positioning and fixing are completed, the electric push rod 403 can be driven to drive its output shaft to push the extrusion plate 404 to descend, and the surface of the extrusion plate 404 is in contact with the surface of the cabinet body, and then the cabinet body is subjected to pressure test, after the pressure test is completed, the cabinet body is further driven by the extrusion plate 404 to resist the fixed effect, and the cabinet body can be further driven by the motor two 305 to perform torsion test in a stable state, and finally the operation process is completed.
