Description

Technical Field

[0001] This utility model relates to the field of inner panel strength testing technology, specifically to a gauge for testing inner panel strength. Background Technology

[0002] A car door consists of an outer door panel, an inner door panel, a door and window frame, a door glass guide channel, door hinges, a door lock, and door and window accessories. The inner panel contains accessories such as window regulators and door locks. In order to ensure a firm assembly, the inner panel needs to have a certain strength. This means that during the production and processing of the inner panel, it is necessary to use a gauge to test the strength of the inner panel.

[0003] Chinese patent publication number "CN208125512U" discloses "a sheet metal strength testing device, including a base, with symmetrically arranged support legs at the bottom of the base, a controller installed on the front surface of the base, symmetrically arranged support plates on both sides of the top of the base, and symmetrically arranged first automatic telescopic rods at the top of the base and between the support plates, with the bottom end of the first automatic telescopic rods penetrating the base and extending into it, and symmetrically arranged worktables at the top of the base and between the first automatic telescopic rods." This patent solves the problem of unstable clamping in sheet metal strength testing devices, avoiding inaccurate testing due to unstable clamping. However, the fixing structure of this patent cannot be adjusted, making it impossible to fix sheets of different sizes, resulting in mediocre actual performance. Furthermore, when testing sheets, those that fail to meet strength standards may break, causing debris to fly into the device, requiring manual cleaning, thus making the device inconvenient to use. Therefore, we propose a gauge for testing the strength of inner sheets. Utility Model Content

[0004] The purpose of this utility model is to provide a gauge for testing the strength of inner panels, in order to solve the problems mentioned in the background art, such as the inability to fix panels of different sizes, resulting in the device's general practical use effect, and the fact that when the device tests the panels, panels that do not meet the strength requirements will break, causing debris to fly into the device, requiring manual cleaning of the debris, thus making the device inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gauge for testing the strength of inner panels, comprising a base, a housing, and a groove. The housing is fixedly connected to the top of the base. The groove is formed on the left and right side walls of the inner cavity of the housing. A workbench is fixedly connected to the middle of the top of the base. A slide rod is fixedly connected to the front of the top of the workbench. A slide table is slidably connected to the outer side wall of the slide rod. A fixed plate is fixedly connected to the rear of the top of the workbench. A first motor is fixedly connected to the right side wall of the fixed plate. A bidirectional lead screw is fixedly connected to the end of the power output shaft of the first motor. The end of the bidirectional lead screw passes through the fixed plate and extends to the inner side wall of the fixed plate. Moving blocks are screwed to the left and right sides of the outer side wall of the bidirectional lead screw. The moving blocks are fixedly connected to the rear side wall of the slide table.

[0006] As a further description of the above technical solution:

[0007] The bottom of the slide is fixedly connected to a movable wheel, the top of the slide is fixedly connected to a placement platform, the top left and right sides of the placement platform are rotatably connected to movable plates, the bottom of the movable plates is fixedly connected to a clamping block, the top left and right sides of the slide are fixedly connected to hydraulic rods, the ends of the hydraulic rods are fixedly connected to connecting blocks, the inner sidewalls of the connecting blocks are rotatably connected to connecting rods, and the ends of the connecting rods are rotatably connected to the left and right sidewalls of the movable plates.

[0008] As a further description of the above technical solution:

[0009] The base has slag discharge troughs on the top left and right sides, and collection boxes are placed on the bottom left and right sides.

[0010] As a further description of the above technical solution:

[0011] A cylinder is fixedly connected to the top center of the inner cavity of the box. A mounting block is fixedly connected to the output end of the cylinder. A pressure sensor is fixedly connected to the bottom of the mounting block. A pressing head is fixedly connected to the bottom of the pressure sensor.

[0012] As a further description of the above technical solution:

[0013] An electric actuator is fixedly connected to the top of the inner cavity of the groove, a lifting block is fixedly connected to the end of the electric actuator, and a frame is fixedly connected to the inner side wall of the lifting block.

[0014] As a further description of the above technical solution:

[0015] The inner sidewall of the frame is provided with a sliding groove. A second motor is fixedly connected to the right sidewall of the inner cavity of the sliding groove. A screw is fixedly connected to the end of the power output shaft of the second motor. A slider is screwed to the outer sidewall of the screw. A crossbar is fixedly connected between the inner sidewalls of the slider. Brush bristles are fixedly connected to the bottom of the crossbar.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The inner panel strength testing fixture uses a first motor to drive a bidirectional lead screw to rotate, which in turn drives a moving block to move. The moving block then drives a slide table to move. Simultaneously, a sliding rod limits the slide table, allowing it to move only left and right, thus preventing it from shifting during movement. This adjusts the distance between the left and right slide tables to match the dimensions of the inner panel, enabling the device to fix inner panels of different sizes and improving its practical performance.

[0018] 2. The inner panel strength testing fixture uses an extended electric push rod to lower the lifting block and bring the brush bristles into contact with the worktable. A second motor then drives a screw to rotate, causing a slider to move a crossbar, which in turn moves the brush bristles to clean the worktable. The brush bristles then sweep the debris into a slag discharge trough, from which the debris falls into a collection box. This allows the device to automatically clean the debris without manual cleaning. Attached Figure Description

[0027] This utility model provides a gauge for testing the strength of inner plates, which can fix inner plates of different sizes, improve the actual use effect of the device, and can automatically clean up debris, eliminating the need for manual cleaning. Please refer to [link / reference]. Figure 1-4 It includes a base 100, a housing 200, and a recess 300;

[0028] Please see Figure 1-3 A workbench 110 is fixedly connected to the top center of the base 100. A slide rod 120 is fixedly connected to the top front side of the workbench 110. A slide table 130 is slidably connected to the outer side wall of the slide rod 120. A fixed plate 140 is fixedly connected to the top rear side of the workbench 110. A first motor 150 is fixedly connected to the right side wall of the fixed plate 140. A double-acting lead screw 160 is fixedly connected to the end of the power output shaft of the first motor 150. The end of the double-acting lead screw 160 passes through the fixed plate 140 and extends to the inner side wall of the fixed plate 140. Moving blocks 170 are screwed to the left and right sides of the outer side wall of the double-acting lead screw 160. Moving blocks 170 are fixedly connected to the rear side wall of the slide table 130. A moving wheel 131 is fixedly connected to the bottom of the slide table 130. A placement platform 132 is fixedly connected to the top of the slide table 130. Movable plates 133 are rotatably connected to the left and right sides of the top of the placement platform 132. The bottom of the movable plates 133 is fixed. A clamping block 134 is connected to the top of the slide 130. Hydraulic rods 135 are fixedly connected to the top left and right sides of the slide 130. A connecting block 136 is fixedly connected to the end of the hydraulic rod 135. A connecting rod 137 is rotatably connected to the inner side wall of the connecting block 136. The end of the connecting rod 137 is rotatably connected to the left and right side walls of the movable plate 133. Slag discharge troughs 180 are opened on the top left and right sides of the base 100. Collection boxes 190 are placed on the bottom left and right sides of the base 100. The first motor 150 drives the bidirectional screw 160 to rotate, so that the bidirectional screw 160 drives the moving block 170 to move. Then, the moving block 170 drives the slide 130 to move. At the same time, the slide rod 120 limits the slide 130 so that the slide 130 can only move left and right, thereby preventing the slide 130 from deviating during the movement. This adjusts the distance between the left and right slides 130 to conform to the size of the inner plate.

[0029] In summary, this allows the device to fix inner plates of different sizes, improving the actual performance of the device.

[0030] Please see Figure 3-4The housing 200 is fixedly connected to the top of the base 100. A groove 300 is formed on the left and right side walls of the inner cavity of the housing 200. A cylinder 210 is fixedly connected to the middle of the top of the inner cavity of the housing 200. A mounting block 220 is fixedly connected to the output end of the cylinder 210. A pressure sensor 230 is fixedly connected to the bottom of the mounting block 220. A pressing head 240 is fixedly connected to the bottom of the pressure sensor 230. An electric push rod 310 is fixedly connected to the top of the inner cavity of the groove 300. A lifting block 320 is fixedly connected to the end of the electric push rod 310. A frame 330 is fixedly connected to the inner side wall of the lifting block 320. A sliding groove 340 is formed on the inner side wall of the frame 330. A second motor 350 is fixedly connected to the right side wall of the inner cavity of the sliding groove 340. The second motor 350... A screw 360 is fixedly connected to the end of the force output shaft. A slider 370 is screwed to the outer wall of the screw 360. A crossbar 380 is fixedly connected between the inner walls of the slider 370. A brush bristle 390 is fixedly connected to the bottom of the crossbar 380. By extending the electric push rod 310, the lifting block 320 drives the frame 330 to descend, thereby causing the brush bristle 390 to contact the worktable 110. Then, the second motor 350 drives the screw 360 to rotate, causing the slider 370 to move the crossbar 380, which in turn causes the crossbar 380 to move the brush bristle 390, thus cleaning the worktable 110 with the brush bristle 390. The brush bristle 390 then sweeps the debris into the slag discharge trough 180, causing the debris to fall from the slag discharge trough 180 into the collection box 190.

[0031] In summary, this allows the device to automatically clean up debris without the need for manual cleaning.

[0032] In practical use, those skilled in the art first drive the bidirectional lead screw 160 to rotate via the first motor 150, causing the bidirectional lead screw 160 to move the moving block 170. Simultaneously, the slide bar 120 limits the slide table 130, causing the moving block 170 to move the slide table 130. Then, the left and right slide tables 130 are adjusted to suitable positions. Next, the hydraulic rod 135 drives the connecting block 136 to descend, causing the connecting rod 137 to pull the movable plate 133 downwards, thereby causing the pressing block 134 to tilt upwards. The inner plate is then placed on the placement platform 132. The hydraulic rod 135 then drives the connecting block 136 to rise, causing the connecting rod 137 to push the movable plate 133 upwards, causing the pressing block 134 to press against the inner plate, thus fixing the inner plate in place. Afterwards... The cylinder 210 drives the pressing head 240 to descend, causing the pressing head 240 to press down on the inner plate. The pressure sensor 230 monitors the pressing pressure to detect the strength of the inner plate. Finally, when the inner plate breaks and the debris splashes onto the worktable 110, the extension electric push rod 310 causes the lifting block 320 to drive the frame 330 to descend, which in turn causes the brush bristles 390 to come into contact with the worktable 110. Then, the second motor 350 drives the screw 360 to rotate, which causes the slider 370 to move the crossbar 380, which in turn causes the crossbar 380 to move the brush bristles 390, thus cleaning the worktable 110. The brush bristles 390 sweep the debris into the slag discharge trough 180, where the debris falls into the collection box 190.
