The drilling process is an important link in the production process of machine tool guideways, and the quality and efficiency of drilling directly affect the overall performance and production cycle of the guideways.
[0003] However, the existing drilling structure used in machine tool guideway production is prone to displacement of the machine tool guideway during use, which leads to deviation in the hole position, affects the production quality of the machine tool guideway, and reduces the subsequent installation and performance of the guideway. Summary of the Invention
[0004] The purpose of this utility model is to provide a punching structure and punching device for machine tool guide rail production. By setting a clamping mechanism, the problem of machine tool guide rail position being easily offset, resulting in deviation of hole position, affecting the production quality of machine tool guide rail, and reducing the subsequent installation and use performance of guide rail is solved.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a punching structure and punching device for machine tool guide rail production, including a base, on which a clamping mechanism and a lowering mechanism are provided;
[0007] The clamping mechanism includes a worktable fixedly connected to the top of the base. A rectangular groove is provided on the worktable, and a rectangular sliding groove is provided on the top of the worktable. A hydraulic cylinder is fixedly connected to the left side of the rectangular groove, and a trapezoidal sliding groove is provided at the bottom of the rectangular groove. The lowering mechanism includes a bracket fixedly connected to the top of the base.
[0008] Furthermore, the inner wall of the trapezoidal groove is slidably connected to a bidirectional hinge block, and the hydraulic cylinder is fixedly connected to the bidirectional hinge block.
[0009] Furthermore, the bidirectional hinge block is hinged with two hinge rods, and each of the two hinge rods is hinged with a clamping plate on the side away from each other. Both clamping plates are slidably connected to the rectangular slide groove.
[0010] Furthermore, several telescopic rods are fixedly connected to the sides of the two clamping plates that are close to each other, and a circular fixing plate is fixedly connected to the sides of the several telescopic rods that are close to each other.
[0011] Furthermore, springs are fitted on the outer walls of several of the telescopic rods, and the sides of the several springs that are close to each other are fixedly connected to several circular fixing plates, while the sides of the several springs that are far apart from each other are fixedly connected to two clamping plates.
[0012] Furthermore, a sliding rod is fixedly connected between the bottom of the bracket and the top of the base, a movable plate is slidably connected to the sliding rod, a threaded rod is rotatably connected between the bottom of the bracket and the top of the base, the threaded rod passes through the movable plate, the threaded rod is threadedly connected to the movable plate, and the top of the threaded rod passes through the bracket and extends outward.
[0013] Furthermore, a motor ring is fixedly connected to the top of the bracket, a motor is fixedly connected to the inner wall of the motor ring, and the output shaft of the motor is fixedly connected to a threaded rod via a coupling.
[0014] A punching device includes a punching mechanism fixedly connected to the bottom of a movable plate.
[0015] This utility model has the following beneficial effects:
[0016] 1. By setting up a clamping mechanism and activating the hydraulic cylinder, the hydraulic cylinder pushes the bidirectional hinge block to move within the trapezoidal slide. At this time, the bidirectional hinge block drives the two hinge rods to rotate on the two clamping plates respectively, reducing the angle between the two hinge rods. Under the action of the reduced angle between the two hinge rods, the two clamping plates slide within the rectangular slide and move closer to each other, thereby causing the circular fixing plate on the telescopic rod to clamp the machine tool guide rail. During clamping, the clamping force will compress the telescopic rod and spring through the circular fixing plate, thereby generating elastic force in the spring. At this time, the various telescopic rods will be compressed to different degrees according to the shape of the machine tool guide rail, thus fixing machine tool guide rails of different shapes. This ensures that the machine tool guide rail is firmly fixed in the designated position, preventing it from moving or shaking, ensuring that the drill bit can accurately drill at the predetermined position, thereby improving the drilling accuracy and precision, and also helping to improve the drilling speed and efficiency.
[0017] 2. By setting up a downward movement mechanism, after fixing, the motor is started. The motor drives the threaded rod to rotate through the coupling. When the threaded rod rotates, it drives the moving plate to slide downward on the slide rod, thereby moving the punching device. The moving plate lowers the height of the punching device to punch holes in the machine tool guide rail. After punching, the motor drives the punching device to rise again through the moving plate. By adjusting the downward movement speed and distance, the punching depth can be accurately controlled to ensure that each hole reaches the design depth, guaranteeing the consistency and accuracy of the punching depth. The uniform downward movement speed can reduce the impact on the guide rail material, reduce the possibility of material deformation and cracking, and thus obtain a high-quality punching effect.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please refer to Figures 1-6. This utility model is a punching structure and punching device for machine tool guide rail production, including a base 1. A clamping mechanism 2 and a lowering mechanism 3 are provided on the base 1. The clamping mechanism 2 includes a worktable 211 fixedly connected to the top of the base 1. A rectangular groove 212 is formed on the worktable 211, and a rectangular sliding groove 213 is formed on the top of the worktable 211. A hydraulic cylinder 214 is fixedly connected to the left side of the rectangular groove 212. A trapezoidal sliding groove 215 is formed at the bottom of the rectangular groove 212. A bidirectional hinge block 216 is slidably connected to the inner wall of the trapezoidal sliding groove 215. The hydraulic cylinder 214 is fixedly connected to the bidirectional hinge block 216. Two hinge rods 217 are hingedly arranged on the bidirectional hinge block 216. A clamping plate 218 is hinged to the side of each hinge rod 217 that is far apart from each other. Each clamping plate 218 is slidably connected to a rectangular slide groove 213. Several telescopic rods 219 are fixedly connected to the side of each clamping plate 218 that is close to each other. A circular fixing plate 2110 is fixedly connected to the side of each telescopic rod 219 that is close to each other. Springs 2111 are sleeved on the outer wall of each telescopic rod 219. The side of each spring 2111 that is close to each other is fixedly connected to several circular fixing plates 2110 respectively. The side of each spring 2111 that is far from each other is fixedly connected to the two clamping plates 218 respectively. By setting the clamping mechanism 2, the machine tool guide rail is firmly fixed in the designated position to prevent it from moving or shaking, ensuring that the drill bit can accurately drill in the predetermined position, thereby improving the accuracy and precision of drilling, and also helping to improve the speed and efficiency of drilling.
[0030] The lowering mechanism 3 includes a bracket 311 fixedly connected to the top of the base 1. A slide rod 312 is fixedly connected between the bottom of the bracket 311 and the top of the base 1. A moving plate 313 is slidably connected to the slide rod 312. A threaded rod 314 is rotatably connected between the bottom of the bracket 311 and the top of the base 1. The threaded rod 314 passes through the moving plate 313 and is threadedly connected to the moving plate 313. The top of the threaded rod 314 passes through the bracket 311 and extends outward. A motor ring 315 is fixedly connected to the top of the bracket 311. A motor 316 is fixedly connected to the inner wall of the motor ring 315. The output shaft of the motor 316 is fixedly connected to the threaded rod 314 through a coupling. By setting the lowering mechanism 3, the drilling depth can be accurately controlled by adjusting the lowering speed and distance, ensuring that each hole reaches the depth required by the design, guaranteeing the consistency and accuracy of the drilling depth. The uniform lowering speed can reduce the impact on the guide rail material, reduce the possibility of material deformation and cracking, thereby obtaining a high-quality drilling effect.
[0031] A punching device includes a punching device 411 fixedly connected to the bottom of a movable plate 313. By setting the punching device 411, a large number of guide rails can be punched in a short time, which can meet production needs and improve production efficiency.
[0032] A specific application of this embodiment is as follows: During use, the machine tool guide rail is placed on the worktable 211, and then the hydraulic cylinder 214 is activated. When the hydraulic cylinder 214 pushes the bidirectional hinge block 216 to move to the left in the trapezoidal slide groove 215, the bidirectional hinge block 216 drives the two hinge rods 217 to rotate on the two clamping plates 218 respectively, reducing the angle between the two hinge rods 217. At this time, under the action of the reduced angle between the two hinge rods 217, the two clamping plates 218 are driven to slide and move closer to each other in the rectangular slide groove 213, thereby driving the telescopic rod 219 to move... The circular fixing plate 2110 clamps the machine tool guide rail. During clamping, the clamping force compresses the telescopic rod 219 and spring 2111 through the circular fixing plate 2110. With the cooperation of the telescopic rod 219 and spring 2111, the spring 2111 generates a stable clamping force. At this time, the degree of compression of the several telescopic rods 219 varies according to the shape of the machine tool guide rail, thus fixing machine tool guide rails of different shapes. After fixing, the motor 316 is started. The motor 316 drives the threaded rod 314 to rotate through the coupling. When rod 314 rotates, it drives the moving plate 313 to slide downwards on the sliding rod 312. Because the sliding rod 312 and the threaded rod 314 are parallel, the moving plate 313 is ensured to move vertically without deviation, thereby driving the punching device 411 to move. The punching device 411 in this device uses a Makita 40V metal punching machine GPP01. Its working principle is as follows: it relies on a 40V lithium battery to power the brushless motor, efficiently converting electrical energy into mechanical energy. Through the transmission mechanism, the punch performs reciprocating linear motion, impacting the metal sheet at high speed. The punch and the blanking base are combined... The punching device 411 is precisely controlled by an adjustable depth guide rail after punching is completed. The punch can automatically reset after punching. The half-punch trigger function can also stop punching and reset the punch at any time. The height of the punching device 411 is lowered by the moving plate 313 to punch the machine tool guide rail. After punching is completed, the motor 316 drives the punching device 411 to rise through the moving plate 313. Then, the output shaft of the hydraulic cylinder 214 shortens, thereby driving the two hinge rods 217 through the bidirectional hinge block 216 to push the two clamping plates 218 away, thereby releasing the fixation of the machine tool guide rail.
