However, in order to meet the position limits of different types of substrates, most existing clamps use a clamping and fixing method to clamp the substrate between various clamps for position limiting. When punching holes in the substrate, the substrate is easily vibrated by the influence of the drill rod, which will cause the substrate to shake up and down between the clamps, thereby causing the substrate to deviate and affecting the punching quality of the substrate. Therefore, those skilled in the art provide a substrate punching device for display cabinet production to solve the problems raised in the above background technology. Utility Model Content

[0022] Combination Figure 1-Figure 5 As shown, a substrate punching device for display cabinet production includes: a workbench 1, a stand 11 is arranged on one side of the top of the workbench 1, a drill 12 for punching holes in the substrate is driven on the stand 11, a limit frame 2 is arranged on the side of the top of the workbench 1 away from the stand 11, an empty slot 201 is opened inside the limit frame 2, and a push plate 21, an adjustment plate 22 and a pressure plate 23 are arranged in sequence inside the empty slot 201, wherein the lower end surface of the push plate 21 is provided with two vertical plates 211 distributed symmetrically, the upper end surface of the adjustment plate 22 is provided with an adjustment frame 221, the adjustment frame 221 is inserted between the two vertical plates 211, and the lower end surface of the push plate 21 is located between the two vertical plates 211 and is rotatably installed with a threaded rod 24, and the threaded rod 24 passes through the adjustment frame 221 is threadedly installed inside it, the adjusting frame 221 can slide between the two vertical plates 211 by rotating the threaded rod 24, and a cylinder 27 is arranged on the top of the limit frame 2, and an extension rod 271 is arranged on the output end of the cylinder 27, and the extension rod 271 passes through the limit frame 2 to extend to the inside of the empty slot 201 and is installed on the upper end surface of the push plate 21, and the pressing plate 23 is arranged below the adjusting plate 22, and positioning rods 25 are arranged at the four corners of the top of the pressing plate 23, and the other end of the positioning rod 25 passes through the adjusting plate 22 and extends to the top thereof, and the pressing plate 23 is slidably installed on the bottom of the adjusting plate 22 through the positioning rod 25, and a buffer spring 26 is arranged on the upper end surface of the pressing plate 23 and the lower end surface of the adjusting plate 22 and around the outside of the positioning rod 25.
[0023] In one embodiment, when the pressure of the pressure plate 23 is changed, the threaded rod 24 can be screwed to drive the adjustment frame 221 installed thereon through the threaded groove 223 to move downward, so that the adjustment frame 221 can slide downward between the two vertical plates 211 through the cooperation of the slider 222 and the slide groove 212, and then the downward sliding adjustment frame 221 pushes the adjustment plate 22 to move downward, and pushes the pressure plate 23 installed on the adjustment plate 22 to move downward, and finally, the limit nuts 241 are screwed to press the two limit nuts 241 on the inner and outer ends of the adjustment frame 221 to limit the adjustment. The position of the frame 221 prevents the adjustment plate 22 from shifting after the adjustment position, shortens the distance between the adjustment plate 22, the pressure plate 23 and the substrate, changes the pressure of the pressure plate 23 pressing the substrate, allows the adjustment plate 22 to press the buffer spring 26 on the outer wall of the positioning rod 25, increases the reaction force of the buffer spring 26, and allows the pressure plate 23 to press the substrate under the reaction force of the buffer spring 26, preventing the substrate from shaking up and down due to the influence of the drill rod, avoiding the situation where the substrate pushes the pressure plate 23 upward to shake due to insufficient pressure on the pressure plate 23, thereby ensuring the stability of the substrate installation.
[0024] In one embodiment, when adjusting the position of the adjustment plate 22, the position of the adjustment frame 221 can be limited by the cooperation of the slider 222 and the slide groove 212 to prevent the adjustment frame 221 from rotating and deviating with the threaded rod 24, thereby ensuring the position adjustment of the adjustment plate 22.
[0025] In one embodiment, since the end face area of the limiting ring 251 is larger than the opening area of the sliding hole 224, the positioning rod 25 can be limited by the limiting ring 251 to prevent the positioning rod 25 from being separated from the adjusting plate 22 at the sliding hole 224, thereby avoiding the situation in which the pressure plate 23 is separated from the adjusting plate 22 due to the positioning rod 25 being separated from the adjusting plate 22 at the sliding hole 224, thereby achieving the limitation of the pressure plate 23.
[0026] In one embodiment, when the limit frame 2 is installed on the workbench 1 for use, the limit frame 2 can be placed on one side of the drilling rig 12, and the fastening bolts 281 on the support ears 28 are screwed to install the fastening bolts 281 on the workbench 1 to complete the installation of the limit frame 2, and then the base plate is placed in the empty slot 201, and the cylinder 27 is driven to work, driving the extension rod 271 installed at its output end to extend, so that the extension rod 271 pushes the push plate 21 to move downward, and then the push plate 21 drives the pressure plate 23 installed thereon through the adjustment plate 22 to move downward, so that the pressure plate 23 is pressed tightly against the upper end surface of the base plate, and the installation is completed. The limit of the substrate can allow the pressing plate 23 to be pressed against the upper end surface of the substrate, and the substrate is pressed against the workbench 1 for limit, so as to prevent the displacement of the substrate, avoid the situation that the punching quality is affected by the displacement of the substrate, and ensure the punching quality of the substrate. Moreover, since the substrate is limited by pressing it, the pressing plate 23 can be pressed against the top of substrates of different models to limit it, which is suitable for limiting the positioning of substrates of different models. Moreover, the pressing plate 23 contacts the surface of the substrate through the contact plate 231 made of rubber material, which can also avoid the trouble of the pressing plate 23 scratching the surface of the substrate, thereby protecting the substrate.
[0027] The working principle of the utility model is as follows: when punching holes in the substrate, the threaded rod 24 can be screwed to drive the adjusting frame 221 installed thereon through the threaded groove 223 to move downward, so that the adjusting frame 221 can slide downward between the two vertical plates 211 through the cooperation of the slider 222 and the slide groove 212, and then the adjusting frame 221 that slides downward pushes the adjusting plate 22 to move downward, and pushes the pressing plate 23 installed on the adjusting plate 22 to move downward, shortening the distance between the adjusting plate 22, the pressing plate 23 and the substrate, and then drives the cylinder 27 to work, driving the extending rod 271 installed at its output end to extend, so that the extending rod 271 pushes the push plate 21 to move downward, and then the push plate 21 drives the adjusting plate 22 installed thereon to move downward. The pressing plate 23 is moved downward so that the pressing plate 23 is pressed tightly against the upper end surface of the substrate, and the positioning of the substrate can be completed. The distance between the pressing plate 23, the adjusting plate 22 and the substrate can be adjusted according to the thickness of the substrate, and the pressure of the pressing plate 23 pressing the substrate can be changed. The adjusting plate 22 presses the buffer spring 26 on the outer wall of the positioning rod 25 to increase the reaction force of the buffer spring 26, so that the pressing plate 23 presses the substrate under the reaction force of the buffer spring 26 to prevent the substrate from shaking up and down due to the influence of the drill rod. This not only avoids the trouble of damaging the surface of the substrate due to the high pressure of the pressing plate 23, but also avoids the situation where the substrate pushes the pressing plate 23 upward to shake due to insufficient pressure of the pressing plate 23, thereby ensuring the stability of the substrate installation.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
