Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically a device for polishing the outer frame of a tennis racket. Background Technology

[0002] The manufacture of tennis rackets is a process that combines materials science, engineering design, and precision manufacturing. Modern tennis rackets typically use composite materials such as carbon fiber to achieve both lightweight and high strength. The formation of a tennis racket involves steps such as design, molding, polishing, painting, and assembly. Among these, the polishing process mainly targets the surface treatment of the frame, aiming to improve aesthetics, reduce air resistance, and increase coating adhesion.

[0003] Typically, a tennis racket polishing device includes a support frame and a body. The body is equipped with a drive motor and a polishing head. When in use, the motor is started, and the motor shaft drives the polishing head to rotate. The tennis racket is held close to the polishing head, so that the surface of the tennis racket comes into contact with the polishing head, and the polishing head can remove the parting lines and burrs on the surface of the tennis racket.

[0004] However, the machine body is usually fixedly connected to the support frame, making it difficult to adjust the direction and angle of use, which reduces the applicability of the grinding device.

[0005] Based on this, the present invention designs a racket outer frame polishing device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A connecting block is fixedly installed directly below the body, and a plurality of limiting gear teeth are fixedly installed on the connecting block. The support frame includes a support plate, a connecting plate, and a limiting plate. The connecting plate is fixedly connected to the support plate, and the limiting plate is slidably located on the support plate. The body is located between the connecting plate and the limiting plate. A disc is rotatably installed on the connecting plate, and the disc is fixedly connected to the connecting block. A telescopic rod is fixedly installed on the connecting plate, and the other end of the telescopic rod is connected to the limiting plate. A limiting tooth groove is fixedly installed on the side of the limiting plate near the connecting block. When the telescopic rod retracts, the limiting tooth groove is pulled to engage with the limiting gear teeth.

[0007] By adopting the above technical solution, the limiting plate is pulled open, causing the limiting tooth groove on the limiting plate to move away from the limiting wheel tooth. The connecting block is rotated, causing the disc on the connecting block to start rotating. The machine body begins to tilt, and the angle of the grinding head on the machine body changes. After adjusting to the required angle, the limiting plate is pushed towards the connecting block, causing the limiting tooth groove to engage with the limiting wheel tooth. This causes the limiting wheel tooth to stop rotating after being limited, and the machine body remains stationary. This achieves the effect of adjusting the grinding direction of the machine body, improving the applicability of the machine body and enhancing the flexibility of the equipment.

[0008] Preferably, the limiting plate is rotatably provided with a handle on the side away from the connecting plate, and when the handle is rotated to the vertical direction, the handle abuts against the side of the support plate.

[0009] By adopting the above technical solution, when the limiting plate is pulled to the side away from the connecting plate, the handle makes it easy for the user to apply force to the limiting plate. At the same time, the rotating handle can fix the limiting plate, making it easy for the user to adjust the direction of the machine.

[0010] Preferably, the telescopic rod includes a bushing and a telescopic shaft, the telescopic shaft is slidably connected to the bushing, a spring is fixedly provided on the side of the bushing away from the telescopic shaft, and the other end of the spring is fixedly connected to the telescopic shaft.

[0011] By adopting the above technical solution, after the telescopic shaft is stretched, the tension of the spring can quickly pull the telescopic shaft back, which can drive the limiting plate to retract quickly, thus strengthening the connection between the limiting plate and the connecting plate and making the limiting plate more stable when limiting.

[0012] Preferably, a base is provided below the support frame, a connecting groove is provided on the base, and a connecting column is fixedly provided at the bottom of the support plate, the connecting column being rotatably connected in the connecting groove.

[0013] By adopting the above technical solution, the support frame can rotate on the base, and the machine body can change in the horizontal direction, which facilitates multi-angle and multi-directional grinding of the racket, thereby improving the grinding effect and precision.

[0014] Preferably, the base has a threaded hole, and a positioning rod is threaded into the threaded hole. One end of the positioning rod passes through the threaded hole and abuts against the connecting column.

[0015] By adopting the above technical solution, the positioning rod is rotated to make it abut against the connecting column, and the connecting column stops rotating in the connecting groove, making the device more stable during use.

[0016] In summary, this application has the following beneficial technical effects: By adopting the above technical solution, the limiting plate is pulled open, causing the limiting tooth groove on the limiting plate to move away from the limiting wheel tooth. The connecting block is rotated, causing the disc on the connecting block to start rotating accordingly. The machine body begins to tilt, and the angle of the grinding head on the machine body changes. After adjusting the required angle, the limiting plate is pushed towards the connecting block, causing the limiting tooth groove to engage with the limiting wheel tooth. This causes the limiting wheel tooth to stop rotating after being limited, and the machine body remains stationary, achieving the effect of adjusting the grinding direction of the machine body. This improves the applicability of the machine body and enhances the flexibility of the equipment. Attached Figure Description

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] A racket outer frame polishing device includes a support frame and a body 1. A connecting block 17 is fixedly installed directly below the body 1. A plurality of limiting gear teeth 15 are fixedly installed on the connecting block 17. The support frame includes a support plate 5, a connecting plate 4 and a limiting plate 3. The connecting plate 4 is fixedly connected to the support plate 5. The limiting plate 3 is slidably located on the support plate 5. The body 1 is located between the connecting plate 4 and the limiting plate 3. A disc 10 is rotatably installed on the connecting plate 4. The disc 10 is fixedly connected to the connecting block 17. A telescopic rod is fixedly installed on the connecting plate 4. The other end of the telescopic rod is connected to the limiting plate 3. The limiting plate 3 is fixedly provided with a limiting tooth groove 14 on the side near the connecting block 17.

[0027] In use, pull the limiting plate 3 to move it away from the connecting block 17. The limiting plate 3 drives the limiting tooth groove 14 away from the limiting wheel tooth 15. After the limiting tooth groove 14 leaves, the limiting wheel tooth 15 is released from restriction. At this time, rotate the machine body 1 up and down to adjust the direction of the grinding head 2 on the machine body 1, so that the disc 10 on the connecting block 17 rotates on the connecting plate 4. After adjusting the required angle, push the limiting plate 3 back to the connecting block 17 so that the limiting tooth groove 14 and the limiting wheel tooth 15 cooperate. The limiting wheel tooth 15 is limited, and the connecting block 17 stops rotating. The tilt angle of the machine body 1 is fixed, achieving the effect of adjusting the grinding direction of the machine body 1 and improving the applicability of the machine body 1.

[0028] A handle 8 is rotatably provided on the side of the limiting plate 3 away from the connecting plate 4. The telescopic rod includes a bushing 9 and a telescopic shaft 16. The telescopic shaft 16 is slidably connected to the bushing 9. A spring 13 is fixedly provided on the side of the bushing 9 away from the telescopic shaft 16. The other end of the spring 13 is fixedly connected to the telescopic shaft 16.

[0029] Pull the limiting plate 3 away from the connecting block 17 by using handle 8. When the limiting plate 3 moves to the side of the support plate 5, rotate handle 8 so that one end of handle 8 is pressed against the side of the support plate 5, and the limiting plate 3 is temporarily limited. At this time, the machine body 1 can be adjusted. After adjusting the use angle of the machine body 1, rotate handle 8 again so that handle 8 is away from the side of the support plate 5. Spring 13 retracts and pulls telescopic shaft 16 back into bushing 9. The limiting plate 3 is then pulled towards the connecting block 17. The limiting tooth groove 14 and the limiting wheel tooth 15 cooperate. Spring 13 increases the connection between the connecting plate 4 and the limiting plate 3, so that the limiting tooth groove 14 will not disengage from the limiting wheel tooth 15 when the machine body 1 is in use, thus increasing the stability of the device.

[0030] A base 7 is provided below the support frame, and a connecting groove 12 is provided on the base 7. A connecting column 11 is fixedly provided at the bottom of the support plate 5. The connecting column 11 is rotatably connected in the connecting groove 12. A threaded hole 18 is provided on the base 7, and a positioning rod 6 is threadedly connected in the threaded hole 18. One end of the positioning rod 6 passes through the threaded hole 18 and abuts against the connecting column 11.

[0031] By rotating the positioning rod 6, one end of the positioning rod 6 is moved away from the connecting column 11. At this time, the support frame is rotated, causing the connecting column 11 below the support frame to start rotating in the connecting groove 12, causing the machine body 1 to rotate horizontally. After adjusting the machine body 1 to the required angle, the positioning rod 6 is rotated again, so that the positioning rod 6 is pressed against the positioning column again. After the connecting column 11 is pressed, it stops rotating, so that the support frame can be stably placed on the base 7. This facilitates the adjustment of the machine body 1's usage direction while ensuring the stability of the device.

[0032] The implementation principle of this embodiment is as follows: During use, the limiting plate 3 is pulled away from the connecting block 17 by the handle 8. The limiting plate 3 drives the limiting tooth groove 14 away from the limiting wheel tooth 15. When the limiting plate 3 moves to the side of the support plate 5, the handle 8 is rotated so that one end of the handle 8 abuts against the side of the support plate 5, and the limiting plate 3 is temporarily limited. After the limiting tooth groove 14 leaves, the limiting wheel tooth 15 is released from restriction. At this time, the machine body 1 is rotated up and down to adjust the direction of the grinding head 2 on the machine body 1, so that... The disc 10 on the connecting block 17 rotates on the connecting plate 4. After adjusting the required angle, the handle 8 is rotated again, causing the handle 8 to leave the side of the support plate 5. The spring 13 retracts, pulling the telescopic shaft 16 back into the bushing 9. The limiting plate 3 is then pulled toward the connecting block 17. The limiting tooth groove 14 engages with the limiting wheel tooth 15, limiting the wheel tooth 15. The connecting block 17 stops rotating, and the tilt angle of the machine body 1 is fixed, achieving the effect of adjusting the grinding direction of the machine body 1.
