Description

Technical Field

[0001] This utility model relates to the field of watch case processing technology, and in particular to a reversible watch case polishing device. Background Technology

[0002] With the rapid development of technology, industries such as machinery, electronics, and jewelry are increasingly demanding higher standards for product surface treatment. In particular, the grinding and polishing of watch cases has become a crucial step in improving product appearance and extending lifespan. This demand is especially pronounced in the processing of complex-shaped watch cases, as their surfaces often contain multiple curves and details, requiring higher precision and uniformity in grinding and polishing.

[0003] However, traditional watch case polishing methods face numerous challenges when dealing with these complex shapes. Most existing watch case polishing equipment uses a fixed design, meaning the watch case must be firmly fixed to the equipment, and the operator then manually adjusts the position of the polishing head to complete the surface treatment. This method is not only inefficient but also makes it difficult to ensure the consistency and uniformity of the polishing, especially when dealing with complex shapes, where the difficulty and error of manual adjustment increase significantly.

[0004] Therefore, there is a need for a reversible watch case polishing device. Utility Model Content

[0005] To overcome the drawback of inconvenient adjustment, this utility model provides a flip-up watch case polishing device.

[0006] A flip-up watch case polishing device includes a support frame, a connecting platform, and a polishing wheel. The connecting platform is connected to the top of the support frame, and the polishing wheel is mounted horizontally on the top of the connecting platform via the connecting frame. The device also includes an adjustment assembly. The adjustment assembly is located in the middle of the connecting platform and includes a mounting frame, a cylinder, a guide platform, a slide, a connecting plate, a second motor, a second pulley assembly, an electric push rod, and a locking block. The mounting frame is located in the middle of the connecting platform, and a cylinder is mounted at the lower part of the mounting frame. A guide platform is located at the output end of the cylinder, and a slide slide is slidably mounted on the guide platform. A connecting plate is symmetrically located on the top of the slide. A second motor is located on one side of each connecting plate away from the other. A second pulley assembly is connected between a rotating shaft inside the connecting base and the output shaft of the second motor. An electric push rod is mounted on the rear side of each connecting plate via the connecting base. A rotating shaft is installed inside the connecting base, and the push rod of each electric push rod is equipped with a locking block.

[0007] As an improvement to the above scheme, it also includes a third motor, gears and racks. The third motor is installed at the bottom of the slide table, and a gear is provided at the output end of the third motor. Racks are provided alternately on the side of the two connecting plates that are close to each other, and the racks mesh with the gears.

[0008] As an improvement to the above solution, it also includes a motor and a pulley assembly. The motor is located in the middle of the connecting platform, and the pulley assembly is located between the output shaft of the motor and the left end of the grinding wheel.

[0009] As an improvement to the above solution, a cover is also included, with a cover located on the top of the slide and positioned outside the gear. As another improvement, the locking block mates with the side of the watch case.

[0010] The beneficial effects and significant advancements of this utility model are as follows:

[0011] This invention, through the design of a cylinder and a slide, can precisely position the watch case directly in front of the polishing wheel. This precise positioning capability ensures the accuracy and consistency of the polishing operation, thereby significantly improving the processing quality. Through the design of the second motor and the second pulley assembly, the automatic flipping operation of the watch case can be easily realized. The other side can be easily polished without manually flipping the watch case. This automation feature simplifies the operation process and significantly improves work efficiency.

[0018] Example: A flip-up watch case polishing device, please see below. Figures 1 to 4As shown, the device includes a support frame 1, a connecting platform 2, a first motor 3, a first pulley assembly 4, a grinding wheel 5, a mounting frame 6, a cylinder 7, a guide table 8, a slide table 9, a connecting plate 10, a second motor 11, a second pulley assembly 12, an electric push rod 13, a locking block 14, a third motor 15, a gear 16, a rack 17, and a cover 18. The top of the support frame 1 is connected to the connecting platform 2. The first motor 3 is horizontally mounted in the middle of the connecting platform 2. The grinding wheel 5 is horizontally mounted on the top of the connecting platform 2 through the connecting frame. The grinding wheel 5 directly contacts the surface of the watch case for grinding and is the main working part of the device. The output shaft of the first motor 3 is connected to the left end of the grinding wheel 5 by a first pulley assembly 4. The first pulley assembly 4 consists of two pulleys and a flat belt. The two pulleys are connected to... The output shaft of motor 3 is connected to the left end of the grinding wheel 5, while the flat belt is sleeved on the two pulleys. The motor 3 drives the pulley assembly 4, which in turn drives the grinding wheel 5 to rotate, thus realizing the grinding and polishing operation. A mounting frame 6 is connected to the middle of the connecting platform 2. A cylinder 7 is vertically embedded at the lower center of the mounting frame 6. The piston rod of the cylinder 7 is connected to a guide platform 8. By extending and retracting the piston rod of the cylinder 7, the guide platform 8 and the components connected to it are pushed up and down to achieve height adjustment. The guide platform 8 is located above the connecting platform 2. A slide table 9 is longitudinally slidably connected to the guide platform 8. By sliding the slide table 9 back and forth, the front and back positions of the watch case are adjusted. The top of the slide table 9 is symmetrically connected to the left and right sides with connecting plates 10. The two connecting plates 10 are mutually... Motor 2 11 is installed on each of the opposite sides. Electric push rods 13 are installed on the rear side of the connecting plate 10 via connecting seats. A rotating shaft is installed inside the connecting seat. The push rods of the electric push rods 13 are connected to locking blocks 14. The extension and retraction of the push rods of the electric push rods 13 achieves the clamping and releasing action of the locking blocks 14 on the watch case. The locking blocks 14 fit into the contact surface with the side of the watch case. The locking blocks 14 are used to clamp the watch case, ensuring its stability during polishing. A pulley assembly 2 12 is connected between the rotating shaft inside the connecting seat and the output shaft of motor 2 11. Pulley assembly 2 12 consists of two pulleys and a flat belt. The two pulleys are respectively connected to the outer end of the rotating shaft inside the connecting seat and the output end of motor 2 11, while the flat belt is fitted onto these two pulleys. On the pulley, motor 21 drives pulley assembly 22, thereby realizing the flipping action of electric push rod 13 and locking block 14 to flip the watch case. Motor 315 is vertically embedded at the bottom center of the slide table 9. The output shaft of motor 315 is connected to gear 16, which is located above the slide table 9. On the side where the two connecting plates 10 are close to each other, racks 17 are connected in an alternating manner. The racks 17 mesh with the gears 16. Motor 315 drives gear 16 to rotate, thereby causing the racks 17 to move the two connecting plates 10 outward. Motor 315 drives gear 16 to rotate in the opposite direction, thereby causing the racks 17 to move the two connecting plates 10 inward. A cover 18 is also connected at the top center of the slide table 9.The cover 18 is located on the outside of the gear 16 and prevents debris from entering the teeth between the gear 16 and the rack 17.

[0019] When the watch case polishing device is needed, the piston rod of cylinder 7 must first be adjusted to extend or retract, thereby moving the guide platform 8 and its connected components up and down to precisely adjust the height. Subsequently, the front and back position of the watch case can be further adjusted by sliding the slide 9 back and forth to ensure that it is in the optimal polishing position.

[0020] Next, the electric pusher 13 is activated, causing its pusher to slowly extend and smoothly move the locking block 14 towards the watch case until the locking block 14 firmly and securely clamps the watch case. This process ensures the stability of the watch case during the polishing process, preventing it from moving or shaking.

[0021] After ensuring that the clamping block 14 is securely held, the grinding and polishing operation can begin. Start the motor 3, which effectively drives the grinding wheel 5 to rotate via the pulley assembly 4. At this time, the operator can flexibly adjust the rotation speed of the grinding wheel 5 and its contact pressure with the watch case according to the actual grinding needs, so as to ensure that the quality and efficiency of grinding and polishing are at their best.

[0022] When the other side of the watch case needs to be polished, the rotation of the polishing wheel 5 should be stopped first to avoid unnecessary damage to the watch case. Next, the motor 2 11 is started. The motor 2 11 drives the rotating shaft inside the connecting seat to rotate through the pulley assembly 2 12. This rotation action then realizes the flipping action of the electric push rod 13 and the locking block 14, so that the watch case can be smoothly and accurately flipped to the other side for the next round of polishing operation.

[0023] After flipping, the positions of cylinder 7 and slide 9 are adjusted again to precisely position the other side of the watch case directly below polishing wheel 5. In this way, both the front and back of the watch case can be precisely and efficiently polished.

[0024] During the polishing process, if it is necessary to adjust the distance between the two connecting plates 10 according to the size or shape of the watch case, the motor 3 15 can be activated. The motor 3 15 drives the gear 16 to rotate, and the rotation of the gear 16 will drive the rack 17, which meshes tightly with it, to move, thereby flexibly changing the distance between the two connecting plates 10 to adapt to watch cases of different sizes. This design not only improves the flexibility of the device, but also greatly enhances its practicality.

[0025] It is worth mentioning that the design of cylinder 7 and slide 9 allows for precise adjustment of the watch case to be directly in front of polishing wheel 5; at the same time, the design of motor 11 and pulley assembly 12 enables easy flipping of the watch case, thus facilitating the polishing of the other side. These operations are all electric, requiring no manual operation, making them more convenient and efficient compared to traditional adjustment methods.

[0026] Following the steps described above, the operator can repeat the polishing process until all surfaces of the watch case that require polishing achieve the desired quality and gloss. Finally, after completing all polishing operations, shut off all motors and cylinders 7, release the locking block 14, and carefully remove the meticulously polished watch case.

[0027] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
