Description

Technical Field

[0001] This utility model relates to the technical field of racket processing equipment, specifically a mechanism for punching holes on both sides of a racket. Background Technology

[0002] In the manufacturing process of rackets, drilling holes is a crucial step. Most existing drilling methods involve manual drilling using a template, which is extremely inefficient, makes it difficult to guarantee the accuracy of the holes, results in unstable product quality, and is prone to missed drilling. Therefore, racket drilling mechanisms have emerged.

[0003] Existing racket drilling mechanisms typically drill holes in one area until a through hole is formed. However, the drilling machine usually generates a strong impact force when drilling through the racket, which can damage the other side, causing issues such as bulging or cracking. After the drilling is damaged, the racket needs to be reworked and re-drilled, which reduces the overall efficiency of the production line.

[0004] Therefore, a perforation mechanism for both the front and back sides of a racket is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a front and back perforation mechanism for rackets. By designing the perforation mechanism, perforation is performed simultaneously on both sides of the racket, reducing impact force. This solves the problem that drilling machines typically generate strong impact force when perforating rackets, which can damage the other side when drilling through it, such as causing bulging or cracking. After perforation damage, the racket needs to be reworked and re-perforated, which reduces the overall efficiency of the production line.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Example: Please see Figure 1 - Figure 4 A racket front and back punching mechanism in this embodiment includes a workbench 1, a support frame 2 fixedly connected to the top of the workbench 1, a plurality of through slots 3 arranged in a straight line on the surface of the support frame 2, a punching mechanism is provided on the support frame 2 through the through slots 3, and a plurality of sliding grooves 14 arranged in a straight line are provided on the surface of the support frame 2, a fixing mechanism is provided on the support frame 2 through the sliding grooves 14. The drilling mechanism includes a movable base 12 disposed on opposite sides of the support frame 2 and a drilling machine 13 disposed on the top of the movable base 12. The support frame 2 is provided with support blocks 4 corresponding to the number of through slots 3 on its side. At least two support blocks 6 are provided on the side of the through slots 3. The two support blocks 6 are centrally symmetrically distributed. The fixing mechanism includes two movable blocks 15 set on the inner wall of the slide 14, a limiting plate 18 corresponding to the number of through slots 3 is provided on the side of the support frame 2, and a fixing block 16 is provided on the side of the movable block 15. In this process, when drilling holes in the racket body 11, it is first attached to the support frame 2 and pushed downwards. When it reaches the inner bottom wall of the through groove 3, the two limiting rods 10 will contact the surface of the racket body 11. At the same time, the circular support piece 5 will also contact the side of the racket body 11 to support it. The racket body 11 is fixed by the fixing mechanism. Then, the drilling mechanism will drive the drilling machine 13 to move through the moving base 12. The moving base 12 is composed of an electric slide bar, an electric slider, a lifting slide rail, etc. Its function is to drive the drilling machine 13 to move horizontally, vertically, forward and backward. The moving base 12 is a well-known and mature technology in the art, so it will not be described in detail in this embodiment, nor will it be shown in detail in the accompanying drawings. The drilling machines 13 on both sides of the support frame 2 are started to drill holes in the racket body 11 simultaneously to avoid damage to the surface of the racket body 11 when drilling through holes. One hole is drilled halfway by a puncher 13 on one side, and then the other half is drilled by a puncher 13 on the other side, in order to avoid generating a large impact force that could damage the racket body 11. At this point, the racket body 11 is fixed, and holes are drilled on both sides simultaneously. This avoids the occurrence of large impact forces during the drilling process, which could damage the other side of the racket. This reduces the rework frequency of the racket body 11, reduces material waste, and improves the overall production line efficiency because frequent rework is no longer required.

[0019] The drilling mechanism also includes a circular support plate 5 fixedly connected to the side of the support block 1 4, a base 7 is provided on the side of the support block 2 6, a connecting rod 1 8 is provided on the side of the base 7, a connecting rod 2 9 is provided at the other end of the connecting rod 1 8, and a limit rod 10 is provided on the side of the connecting rod 2 9. The racket body 11 is provided on the side of the through groove 3. The circular support plate 5 is in contact with the side of the racket body 11. The bottom of the racket body 11 is in contact with the inner bottom wall of the through groove 3. The side of the racket body 11 is in contact with the side of the support frame 2. The base 7 is fixedly connected to the connecting rod 8. The angle between connecting rod 18 and connecting rod 29 is obtuse, and the angle between limiting rod 10 and connecting rod 29 is acute. One end of limiting rod 10 is in contact with the surface of racket body 11, and the output ends of the two punching machines 13 are respectively opposite to the two sides of the support frame 2. Before drilling the racket body 11, one side of it is first brought into contact with the surface of the support frame 2, and then pushed downwards until it reaches the inner top wall of the through groove 3. At this time, because the angle between connecting rod 1 8 and connecting rod 2 9 is obtuse, the position of connecting rod 2 9 will be tilted relative to the racket body 11. The limiting rod 10 passes through one side of connecting rod 2 9 and contacts the surface of the racket body 11. It forms an acute angle with connecting rod 2 9, thus providing strong support for the racket body 11. After the moving bases 12 on both sides are activated, the drilling machine 13 is driven to the designated position and the drilling begins. The drilling machine 13 on one side directly drills the racket body. A hole is punched on the surface of the racket body 11, and a hole puncher 13 on the other side punches a hole through the through groove 3 on the surface of the racket body 11. Simultaneous punching avoids damage to the racket body 11 due to large impact force. When the hole puncher 13 on the front punches the racket body 11, the racket body 11 will not move because it is in contact with the surface of the support frame 2. When the hole puncher 13 on the other side punches the racket body 11, the racket body 11 will not move because the two limit rods 10 support it. During punching, the racket body 11 will maintain a stable position to avoid shaking and thus failure to punch. At this time, holes are drilled in the racket body 11, and during the drilling process, it will not easily shake and cause drilling failure, which improves the stability of the device, reduces the frequency of errors, reduces material waste, and improves the working efficiency of the device.

[0020] The fixing mechanism also includes an L-shaped connecting rod 17 fixedly connected to the side of the movable block 15 and a sleeve 19 disposed on the side of the L-shaped connecting rod 17. A piston 20 is disposed inside the sleeve 19, and a sliding rod 21 is disposed on the sleeve 19 through the piston 20. A spring 22 is sleeved on the outer wall of the sliding rod 21. The piston 20 is slidably connected to the inner wall of the slide rod 21, the slide rod 21 passes through the piston 20, the slide rod 21 is fixedly connected to the piston 20, one end of the slide rod 21 passes through one end of the sleeve 19, and the slide rod 21 is slidably connected to the sleeve 19. The other end of the slide rod 21 passes through the L-shaped connecting rod 17, and the slide rod 21 is slidably connected to the L-shaped connecting rod 17. One end of the slide rod 21 extends into the limiting plate 18, and the slide rod 21 is slidably connected to the limiting plate 18. The spring 22 is located inside the sleeve 19. One end of the spring 22 is fixedly connected to the side of the piston 20, and the other end of the spring 22 is fixedly connected to the inner wall of the sleeve 19. After the racket body 11 is placed, the slide rod 21 is pulled, which drives the piston 20 to slide within the sleeve 19. At this time, the spring 22 is in a compressed state. After the slide rod 21 leaves the limiting plate 18, the L-shaped connecting rod 17 is pulled, which drives the moving block 15 to move within the slide groove 14 until the two fixing blocks 16 fix the top of the racket body 11. Then the slide rod 21 is released. At this time, under the reset action of the spring 22, the piston 20 drives the slide rod 21 to reset to the initial position. At this time, the slide rod 21 will be inserted into the limiting plate 18 to fix the position of the L-shaped connecting rod 17. At the same time, the position of the fixing block 16 is fixed, so that the fixing block 16 firmly clamps the top of the racket body 11. At this time, racket bodies 11 of different sizes can be fixed, and the racket body 11 is fixed so that its position is more stable during the drilling process, reducing the probability of error. At this point, the racket body 11 is further fixed, making its position more stable during the drilling process, reducing the probability of errors, improving the overall working efficiency of the device, and being more flexible, it can fix racket bodies 11 of different sizes, thus improving the applicability of the device.
