DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4As shown, a device for testing the anti-deformation ability of cabinet door panels comprises a test bench 1, a support seat 2 is symmetrically arranged on the upper surface of the test bench 1, a sleeve 3 is arranged on the upper end of the support seat 2, a through groove 4 is symmetrically opened on the upper surface of the test bench 1, the support seat 2 is slidably connected to the through groove 4, a limiting plate 5 is arranged at the bottom of the support seat 2, the through groove 4 is located between the support seat 2 and the limiting plate 5, a fixing seat 6 is arranged on the lower surface of the limiting plate 5, a bidirectional screw rod 7 is arranged on the lower surface of the test bench 1, the fixing seat 6 is threadedly connected to the bidirectional screw rod 7, the threads of the two fixing seats 6 have opposite rotation directions, and a servo motor 8 for driving the bidirectional screw rod 7 to rotate is also included, a mounting frame 9 is arranged on the upper surface of the test bench 1, a pressure sensor 10 is arranged inside the upper end of the mounting frame 9, and the pressure sensor A hydraulic cylinder 11 is provided on the lower surface of 10, and a top block 12 is provided on the output end of the hydraulic cylinder 11. Partitions 13 are respectively provided on both sides of the mounting frame 9, and a rotating shaft 14 is symmetrically provided on the outer surface of the partition 13. A gear 15 is provided on the rotating shaft 14, and racks 16 are respectively provided on the upper and lower sides of the gear 15. A slot 17 is provided on the outer surface of the mounting frame 9, and the rack 16 is located inside the slot 17. A fixed rod 18 is provided at one end of two racks 16 located at the same height, and a movable rod 19 is provided at the other end of the other two racks 16. One end of the movable rod 19 is rotatably connected to one of the racks 16, and a limiting groove 20 for accommodating the movable rod 19 is provided on the other rack 16. Abutment rods 21 are provided on both the fixed rod 18 and the movable rod 19.

[0018] The support seat 2 supports the cabinet door panel through the sleeve 3, and the sleeve 3 is rotatably connected to the support seat 2. When the hydraulic cylinder 11 applies downward pressure to the cabinet door panel through the top block 12, the local friction force of the sleeve 3 on the surface of the cabinet door panel can be reduced through the rolling friction between the sleeve 3 and the cabinet door panel, which is convenient for protecting the cabinet door panel. At the same time, blocks 22 are respectively provided at both ends of the sleeve 3. The cross-sections of the block 22 and the sleeve 3 are both circular, and the outer diameter of the block 22 is larger than the outer diameter of the sleeve 3. The block 22 can limit the lateral movement of the cabinet door panel and improve the stability of the cabinet door panel during the anti-deformation test.

[0019] The limit plate 5 can prevent the support seat 2 from escaping from the test bench 1, and by controlling the rotation of the bidirectional screw 7 through the servo motor 8, the two fixed seats 6 can be controlled to move towards or away from each other, thereby controlling the distance between the two support seats 2, thereby adjusting the distance between the two sleeves 3, so as to facilitate the test of the anti-deformation ability of cabinet door panels of different lengths.

[0020] When the hydraulic cylinder 11 applies downward pressure to the cabinet door panel through the top block 12, according to the mutuality of force, the same force will also be applied to the pressure sensor 10, so as to facilitate the control of the force applied by the hydraulic cylinder 11. Through the proportional reversing valve and the displacement sensor, the moving distance of the output end of the hydraulic cylinder 11 can be obtained. According to the relationship between the applied downward pressure and the distance, the anti-deformation ability of the cabinet door panel can be obtained. The greater the downward pressure, the smaller the moving distance of the output end of the hydraulic cylinder 11, and the stronger the anti-deformation ability of the cabinet door panel, and vice versa.

[0021] The movable rod 19 can be rotated. When it is necessary to place the cabinet door panel on the test bench 1, the movable rod 19 is controlled to rotate and one end of the movable rod 19 is moved out of the limiting groove 20, so that the cabinet door panel can be placed on the two sleeves 3 on the test bench 1. After the cabinet door panel is placed, in order to facilitate the top block 12 to more accurately apply downward pressure to the middle part of the cabinet door panel, it is necessary to adjust the position of the cabinet door panel. Specifically, the movable rod 19 is first rotated to move one end of the movable rod 19 into the limiting groove 20. The inner bottom of the limiting groove 20 and the end of the movable rod 19 are embedded with magnet blocks 23 that attract each other, so as to improve the matching stability of the movable rod 19 and the limiting groove 20. At this time, the rack 16 can be pushed to move by the movable rod 19. Through the matching of the rack 16 and the gear 15 The movable rod 19 is engaged, driving the rack 16 on the other side of the gear 15 to move, thereby causing the fixed rod 18 and the movable rod 19 to move in a direction approaching each other, and the cabinet door panel is adjusted to a suitable position through the movable rod 19 and the abutment rod 21 on the fixed rod 18, so that the distance between the two ends of the cabinet door panel and the top block 12 is the same. At the same time, the upper surfaces of the fixed rod 18 and the movable rod 19 are provided with scale lines for measuring the length of the cabinet door panel, which can more accurately move the center position of the cabinet door panel to just below the top block 12. In order to improve the convenience of using the scale lines, the origin of the scale lines is located in the middle position of the movable rod 19 and the fixed rod 18. The width of the cabinet door panel can be measured on both sides of the origin. By observing the scales on both sides of the origin, it is convenient to accurately adjust the position of the cabinet door panel.

[0022] Working principle: first, move the movable rod 19 out of the limiting groove 20 on the rack 16, place the cabinet door panel on the two sleeves 3, and then move one end of the movable rod 19 into the limiting groove 20, and then push the movable rod 19. The movable rod 19 pushes the rack 16 to move, and the rack 16 engages with the gear 15 to drive the rack 16 on the other side of the gear 15 to move, so that the fixed rod 18 and the movable rod 19 can approach each other. When the abutment rod 21 on the fixed rod 18 and the movable rod 19 can both contact the cabinet door panel, the position of the cabinet door panel is fine-tuned through the scales on the movable rod 19 or the fixed rod 18. After the position adjustment of the cabinet door panel is completed, the hydraulic cylinder 11 squeezes the cabinet door panel through the top block 12, so that the anti-deformation ability of the cabinet door panel can be tested.

[0023] The device can quickly adjust the cabinet door panel to a suitable position by controlling the movement of the movable rod 19, and can achieve fine adjustment of the cabinet door panel through the scale line, thereby improving the placement efficiency of the cabinet door panel and saving testing time. At the same time, the device can also test cabinet door panels of different lengths, with a wide testing range and good use effect.
