Description

Technical Field

[0001] This utility model relates to the technical field of racket processing equipment, specifically a grip fixing clamp for racket processing. Background Technology

[0002] In the badminton racket manufacturing process, the assembly of the shaft and grip is a key step that determines product quality. The shaft needs to be precisely inserted into the top of the grip to achieve a stable connection. In existing processing technologies, a side-rail fixing scheme is commonly used: after the racket shaft is positioned and fixed, parallel guide rails are set on both sides of the grip, and the grip slides along the guide rails to complete the docking and insertion action with the shaft.

[0003] However, this process has significant drawbacks: the handle relies solely on guide rails on both sides for guidance, lacking an effective limiting structure at the top. During the sliding connection process, the handle is prone to lateral shift or longitudinal tilting due to uneven force, causing the connection center axis between the support rod and the handle to deviate from the preset position. This instability directly affects the quality of subsequent resin bonding processes, potentially causing uneven adhesive layer distribution and insufficient bonding strength. This not only increases the defect rate but also requires additional steps for correction, hindering the improvement of production efficiency. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a grip fixing clamp for racket processing.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a grip fixing fixture for racket processing, including a processing table, a support platform and a control box fixedly installed on the upper end of the processing table, and a placement groove provided on the support platform, in which a support rod is placed; A clamping frame is slidably mounted on the upper end of the processing table, and a second propulsion component is fixedly mounted on the front end of the processing table. The output end of the second propulsion component is provided with a second push rod connected to the clamping frame. The clamping frame is provided with a clamping groove. Two first propulsion components are symmetrically arranged on both sides of the clamping frame. Two clamping blocks are symmetrically arranged inside the clamping groove. A limiting groove is provided on the inner side of the clamping block. The output end of the first propulsion component is provided with a first push rod that penetrates the clamping frame and connects to the clamping block.

[0006] Furthermore, an improvement of this utility model is that a lifting assembly is fixedly installed above the support platform, and a pressure plate is provided at the output end of the lifting assembly, with the pressure plate located above the support platform.

[0007] To facilitate the assembly of the lifting assembly, the present invention includes the following improvement: two side plates are symmetrically arranged on both sides of the support platform, and the lifting assembly is fixed above the support platform by a support rod.

[0008] To improve the stability of the clamping frame during sliding, the present invention includes the following improvements: the upper end of the processing table is provided with a sliding groove, and the lower end of the clamping frame is provided with a slider that is slidably connected to the sliding groove, the slider having a T-shaped cross-section.

[0009] Furthermore, the improvements of this utility model include that both the first propulsion component and the second propulsion component adopt electric push rods, and the lifting component adopts an electric lifting rod.

[0010] To improve the clamping stability of the gripping block on the handle, the present invention includes an anti-slip texture on the inner wall of the limiting groove.

[0011] Place the support rod in the placement slot and start the lifting assembly to press the pressure plate down and fix the support rod in the placement slot. Further, the grip that needs to be assembled is placed in the clamping groove, so that the front end of the grip contacts the front end of the clamping groove. Then, the two first propulsion components are activated so that the two clamping blocks clamp and fix the grip in the clamping groove. The second propulsion component is then activated, which pushes the clamping frame to move steadily with the handle, so that one end of the placement slot is inserted into the reserved hole at the rear end of the handle.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a grip fixing clamp for racket processing, which has the following beneficial effects: After the support rod is initially positioned by the placement slot of the bearing platform, it is fixed for the second time by the pressure plate driven by the lifting component to ensure that the support rod does not shift during the docking process; the handle is positioned by the clamping slot of the clamping frame, and with the clamping blocks and anti-slip texture driven by the first propulsion components on both sides, multi-directional limiting is achieved to completely avoid lateral displacement or longitudinal tilt of the handle.

[0013] The clamping frame slides into the groove of the processing table via a T-shaped slider, and combined with the second push rod driven by the second propulsion component, it keeps the grip on a straight trajectory during movement, ensuring that the support rod and the grip docking center axis are precisely aligned.

[0016] 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.

[0017] Please see Figures 1-4 This utility model proposes a grip fixing fixture for racket processing, including a processing table 7, a support platform 1 and a control box 6 fixedly installed on the upper end of the processing table 7, and a placement groove 2 provided on the support platform 1, in which a support rod 3 is placed; A clamping frame 9 is slidably mounted on the upper end of the processing table 7. A second propulsion component 13 is fixedly mounted on the front end of the processing table 7. The output end of the second propulsion component 13 is provided with a second push rod connected to the clamping frame 9. The clamping frame 9 is provided with a clamping groove 10. Two first propulsion components 11 are symmetrically arranged on both sides of the clamping frame 9. Two clamping blocks 12 are symmetrically arranged inside the clamping groove 10. A limiting groove 14 is provided on the inner side of the clamping block 12. The output end of the first propulsion component 11 is provided with a first push rod that passes through the clamping frame 9 and connects to the clamping block 12.

[0018] Both the first propulsion assembly 11 and the second propulsion assembly 13 use electric push rods, and the lifting assembly 4 uses an electric lifting rod.

[0019] First, place the support rod 3 into the placement slot 2 of the support platform 1, and start the lifting assembly 4 above the support platform 1 through the control box 6; A lifting assembly 4 is fixedly installed above the support platform 1. The output end of the lifting assembly 4 is provided with a pressure plate 5, which is located above the support platform 1.

[0020] Two side plates are symmetrically arranged on both sides of the support platform 1, and the lifting assembly 4 is fixed above the support platform 1 by a support rod.

[0021] The lifting assembly 4 is fixed above the support platform 1 by the side plates on both sides through the support rods. The pressure plate 5 connected to its output end descends accordingly, pressing down and fixing the support rod 3 in the placement slot 2 to ensure the stability of the support rod 3 in subsequent processes.

[0022] Then, the grip to be assembled is placed into the clamping groove 10 of the clamping frame 9, so that the front end of the grip fits and is positioned with the front end of the clamping groove 10.

[0023] The inner wall of the limiting groove 14 is provided with anti-slip texture.

[0024] Next, the first push assembly 11, which is symmetrically arranged on both sides of the clamping frame 9, is activated by the control box 6. The first push rod at its output end passes through the clamping frame 9 and pushes the two symmetrical clamping blocks 12 in the clamping groove 10 to move towards each other. The limiting groove 14 on the inner side of the clamping block 12 forms a stable clamping of the handle. The anti-slip texture on the inner wall of the limiting groove 14 further enhances the friction and prevents the handle from sliding during the clamping process.

[0025] The upper end of the processing table 7 is provided with a sliding groove 8, and the lower end of the clamping frame 9 is provided with a slider that is slidably connected to the sliding groove 8. The slider has a T-shaped cross section.

[0026] Finally, the second propulsion component 13 fixed at the front end of the processing table 7 is activated. The second push rod at its output end pushes the clamping frame 9 to move. The T-shaped slider at the lower end of the clamping frame 9 slides smoothly along the slide groove 8 at the upper end of the processing table 7, causing the clamped and fixed handle to accurately approach the support rod 3. Finally, one end of the support rod 3 is smoothly inserted into the reserved hole at the rear end of the handle, completing the docking process.

[0027] The side plate and support rod provide stable support for the lifting assembly 4. The control box 6 coordinates the movements of each propulsion assembly and the lifting assembly 4, realizing the automated linkage of the support rod 3 fixing, handle clamping and docking process, reducing manual intervention, reducing the defect rate and significantly improving processing efficiency.

[0028] Clamping frame 9 structure: It is made of aluminum alloy profiles (such as 6061-T6) spliced ​​together. The lightweight design ensures rigidity. The inner side is opened with a limiting groove 14, and the groove wall is milled with anti-slip texture (serrated or grid-like) to enhance friction.

[0029] Slider: A T-shaped slider is fixed to the lower end of the clamping frame 9. The material is 45# steel and the surface is plated with hard chrome (thickness ≥ 0.05mm). It forms a precision fit with the slide groove 8 of the processing table 7.

[0030] Lifting component 4: an electric lifting rod (servo electric cylinder optional) is selected. The main body is a stainless steel cylinder body with internal ball screw drive. The output end is connected to pressure plate 5. Pressure plate 5 is made of 45# steel, with anti-slip rubber pads pasted on the bottom surface. It is bolted to the side plate of the support platform 1 through support rods (round steel or square tube).

[0031] Clamping blocks 12: are arranged in pairs in the clamping groove 10. The material is tool steel (such as Cr12), which has been quenched and tempered (HRC58-62). An arc-shaped limiting groove adapted to the grip is opened on the inner side. The inner wall of the limiting groove 14 is knurled to form anti-slip texture.

[0032] First propulsion component 11: adopts industrial-grade electric push rod (DC servo type), with an aluminum alloy shell. The push rod end is equipped with a universal coupling to ensure uniform force when pushing the clamping block 12. The stroke can be adjusted by the control box 6.

[0033] The second propulsion component 13 uses a high-thrust electric push rod (trapezoidal screw type optional), which is fixed to the front end of the processing table 7. The push rod is connected to the clamping frame 9 through a pin and has a power-off self-locking function to ensure stable position during docking.

[0034] Control chassis 6: Controller: Built-in PLC (such as Siemens S7-1200 or Mitsubishi FX3U), integrated relay module and servo driver, panel setting buttons and display screen, supports manual / automatic mode switching.

[0035] Drive system: Each electric linear actuator is driven by a DC servo motor, and a matching encoder is used to realize closed-loop position control to ensure movement accuracy.
