Description

Technical Field

[0001] This utility model relates to the technical field of watch bezel processing equipment, specifically to a watch bezel polishing machine. Background Technology

[0002] The bezel is a component of the watch case, usually made of metal. It serves to decorate and protect the internal parts of the watch. During production, the outer surface of the bezel needs to be polished to create a sandblasted texture, giving the bezel a hazy appearance.

[0003] Currently, bezel polishing machines are used to polish watch bezels. These machines mainly consist of a clamping mechanism and a polishing mechanism. The clamping mechanism holds the bezel in place, while the friction components (sand belt or grinding wheel) on the polishing mechanism polish the bezel. However, in traditional bezel polishing devices, the friction components exert excessive pressure on the bezel during operation, which can easily damage the bezel. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a watch bezel polishing machine. The friction component and the watch bezel are elastically engaged from top to bottom, which avoids excessive pressure from the friction component on the watch bezel during the polishing process and prevents damage to the watch bezel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bezel polishing machine includes a frame, a clamping mechanism, a polishing mechanism, and a first driving component disposed on the frame. The first driving component drives the clamping mechanism and the polishing mechanism to move closer to or further away in the vertical direction.

[0007] The polishing mechanism has a first base and a polishing assembly, the polishing assembly is disposed on the first base, and a friction element is provided on the polishing assembly;

[0008] The clamping mechanism has a base, a second base, a clamping assembly, and a buffer spring. The second base is slidably mounted on the base. The clamping assembly is mounted on the second base and can clamp the bezel. The buffer spring is located between the second base and the base. The friction element is located above the clamping assembly. During operation, the buffer spring keeps the bezel on the clamping assembly in elastic contact with the friction element in the vertical direction.

[0009] By setting up a clamping mechanism consisting of a base, a second base, a clamping assembly, and a buffer spring, the second base is slidably mounted on the base. The buffer spring is located between the second base and the base. The clamping assembly is mounted on the second base, and the friction element is located on the front side of the clamping assembly. During operation, the buffer spring generates an elastic force in the vertical direction on the second base and the clamping assembly, so that the bezel on the clamping assembly and the friction element maintain elastic contact in the vertical direction. This prevents excessive pressure from the friction element on the bezel during bezel polishing and avoids damage to the bezel.

[0010] In one embodiment, the buffer spring is a compression spring, with its upper end abutting against the second base and its lower end abutting against the base.

[0011] In one embodiment, a limiting component is provided between the second base and the base, the limiting component restricting the upward movement of the second base.

[0012] In one embodiment, the clamping mechanism further includes a first positioning block and a second positioning block, with the clamping assembly located between the first positioning block and the second positioning block, the first positioning block and the second positioning block restricting the friction member from continuing to polish the bezel.

[0013] In one embodiment, the first positioning block is provided with a first positioning surface, and the second positioning block is provided with a second positioning surface. Both the first positioning surface and the second positioning surface extend obliquely from top to bottom toward the clamping component.

[0014] In one embodiment, the first positioning block is mounted on the second base via a support column. The support column is provided with an adjustment seat and an adjustment screw. The first positioning block is mounted on the adjustment seat, and the adjustment screw adjusts the distance between the first positioning block and the second positioning block via the adjustment seat.

[0015] In one embodiment, both the first positioning block and the second positioning block are made of tungsten steel.

[0016] In one embodiment, the grinding assembly is provided with a pressure seat, the pressure seat is provided with a contour block, and wear-resistant parts are provided on both the left and right sides of the lower end of the contour block. The outer wall of the wear-resistant parts has a guide surface, and the friction element is a sanding belt, which is wound around the lower part of the contour block.

[0017] In one embodiment, the frame is provided with a water tank and a spray nozzle, and the clamping mechanism is located in the water tank.

[0018] In one embodiment, the frame is provided with a second driving member, which drives the water tank and the clamping mechanism located in the water tank to move.

[0019] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, by setting up a clamping mechanism consisting of a base, a second base, a clamping assembly, and a buffer spring, the second base is slidably mounted on the base, the buffer spring is located between the second base and the base, the clamping assembly is mounted on the second base, and the friction element is located on the front side of the clamping assembly. During operation, the buffer spring generates an elastic force in the vertical direction on the second base and the clamping assembly, so that the bezel on the clamping assembly and the friction element maintain elastic contact in the vertical direction. Thus, during the bezel polishing process, the friction element avoids excessive pressure on the bezel, preventing damage to the bezel.

Detailed Implementation

[0032] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] like Figures 1-9 As shown, this utility model discloses a watch bezel polishing machine, including a frame 10, and a clamping mechanism 20, a polishing mechanism 30, and a first driving member 11 disposed on the frame 10. The first driving member 11 drives the clamping mechanism 20 and the polishing mechanism 30 to move closer or further away in the vertical direction. Specifically, the first driving member 11 drives the polishing mechanism 30 to move up and down. The first driving member 11 can be driven by a lead screw and a motor, or it can be driven by a linear motor.

[0035] The polishing mechanism 30 has a first base 31 and a polishing component 32. The polishing component 32 is disposed on the first base 31 and has a friction element 33.

[0036] The clamping mechanism 20 has a base 21, a second base 22, a clamping assembly 23, and a buffer spring (not shown). The second base 22 is slidably mounted on the base 21 via a guide rod 211. The clamping assembly 23 is mounted on the second base 22 and can clamp the bezel 40. The buffer spring is located between the second base 22 and the base 21. The friction element 33 is located above the clamping assembly 23. During operation, the buffer spring keeps the bezel 40 on the clamping assembly 23 in elastic contact with the friction element 33 in the vertical direction.

[0037] The buffer spring is a compression spring. The upper end of the compression spring abuts against the second base 22, and the lower end of the compression spring abuts against the base 21. It can be understood that the buffer spring can also be a tension spring.

[0038] A limiting component 24 is provided between the second base 22 and the base 21, and the limiting component 24 restricts the second base 22 from moving upward; by setting the limiting component 24, the second base 22 is prevented from detaching from the base 21 upward.

[0039] The limiting component 24 has a limiting block 241 and a limiting groove 242. The limiting block 241 is provided with a hook 2411, which is movably disposed in the limiting groove 242. The hook 2411 abuts against the inner top wall of the limiting groove 242 to restrict the upward movement of the second base 22. For example, the limiting block 241 is disposed on the second base 22, and the limiting groove 242 is disposed on the base 21.

[0040] The clamping mechanism 20 also has a first positioning block 25 and a second positioning block 26. The clamping assembly 23 is located between the first positioning block 25 and the second positioning block 26. The first positioning block 25 and the second positioning block 26 restrict the friction member 33 from continuing to polish the bezel 40. By setting the first positioning block 25 and the second positioning block 26, when the friction member abuts against the first positioning block 25 and the second positioning block 26, the friction member 33 can be restricted from continuing to polish the bezel 40, thereby preventing over-polishing of the bezel 40.

[0041] The first positioning block 25 has a first positioning surface 251 corresponding to the upper surface of one side of the bezel 40, and the second positioning block 26 has a second positioning surface 261 corresponding to the upper surface of the other side of the bezel 40. Both the first positioning surface 251 and the second positioning surface 261 extend obliquely from top to bottom toward the clamping assembly 23. Before the bezel 40 is polished, the first positioning surface 251 and the second positioning surface 261 are slightly lower than the upper surface of the bezel 40. During the process of the friction member 33 continuously polishing the bezel 40, when the friction member 33 abuts against the first positioning surface 251 or the second positioning surface 261, the first positioning surface 251 or the second positioning surface 261 restricts the friction member 33 from continuing to polish the bezel 40.

[0042] The first positioning block 25 is mounted on the second base 22 via a support column 27. The support column 27 is provided with an adjustment seat 28 and an adjustment screw 29. The first positioning block 25 is mounted on the adjustment seat 28. The adjustment screw 29 adjusts the distance between the first positioning block 25 and the second positioning block 26 via the adjustment seat 28. By setting the adjustment seat 28 and the adjustment screw 29, the distance between the first positioning block 25 and the second positioning block 26 can be adjusted to improve the positioning accuracy, thereby improving the polishing accuracy of the bezel 40.

[0043] Specifically, the adjusting seat 28 is slidably disposed on the support seat, the adjusting screw 29 is threadedly connected to the adjusting seat 28, and a sliding groove 281 and a sliding rail 271 are provided between the adjusting seat 28 and the support column 27. The sliding groove 281 and the sliding rail 271 cooperate to allow the adjusting seat 28 to be slidably disposed on the support seat, and the sliding groove 281 is a dovetail groove.

[0044] The support column 27 is also provided with a connecting block 272, and the connecting block 272 is provided with a slot 2721. The head 291 of the adjusting screw 29 cooperates with the slot 2721 to restrict the axial movement of the adjusting screw 29. The head 291 can rotate around the axis of the adjusting screw 29 in the slot 2721. During adjustment, the adjusting screw 29 is rotated, and the adjusting screw 29 drives the adjusting seat 28 to move away from the second positioning block 26. The adjusting seat 28 drives the first positioning block 25 to move, thereby increasing the distance between the first positioning block 25 and the second positioning block 26.

[0045] The first positioning block 25 and the second positioning block 26 are both made of tungsten steel. By using tungsten steel to form the first positioning block 25 and the second positioning block 26, the first positioning block 25 and the second positioning block 26 have good wear resistance, thereby limiting the friction component 33 from continuing to polish the bezel 40.

[0046] The mounting structure of the second positioning block 26 is the same as that of the first positioning block 25, so it will not be described again.

[0047] The clamping assembly 23 has a chuck 231 and a cylinder 232. The cylinder 232 can drive the chuck 231 to open and close, so that the chuck 231 clamps or releases the bezel 40. The chuck 231 is located between the first positioning block 25 and the second positioning block 26. The structure of the cylinder 232 driving the chuck 231 to open and close is a mature existing technology.

[0048] The clamping mechanism 20 is provided with a protective cover 201. The upper end of the protective cover 201 is provided with a clearance opening 2011 for the clamping component 23, the first positioning block 25 and the second positioning block 26 to extend upward. By setting the protective cover 201, when polishing the bezel 40, debris is prevented from entering the connection between the second base 22 and the base 21, so that the second base 22 can slide smoothly up and down.

[0049] The grinding assembly 32 is provided with a pressure seat 34, and a contour block 35 is provided on the pressure seat 34. Wear-resistant parts 36 are provided on both the left and right sides of the lower end of the contour block 35. The outer wall of the wear-resistant parts 36 has a guide surface 361. The wear-resistant parts 36 are all made of tungsten steel. The friction element 33 is a sanding belt, which is wound around the lower part of the contour block 35. By setting the wear-resistant parts 36 and the guide surface 361 on the outer wall of the wear-resistant parts 36, the guide surface 361 guides the sanding belt, so that the area where the wear-resistant parts 36 are in close contact with the sanding belt has good wear resistance and smooth sliding, avoiding excessive wear of the contour block 35 and the generation of gaps, thereby improving the service life of the contour block 35.

[0050] The frame 10 is equipped with a water tank 12 and a water spray nozzle 13. The clamping mechanism 20 is located in the water tank 12. During operation, the water spray nozzle 13 can spray water onto the friction component 33 and the bezel 40. Specifically, the water spray nozzle 13 includes a first water spray nozzle 131 and a second water spray nozzle 132. The first water spray nozzle 131 is located in the water tank 12 and sprays water onto the bezel 40. There are two second water spray nozzles 132, which are located on the first base 31 and spray water onto the friction component 33. By setting up the water tank 12 and the water spray nozzle 13, and with the clamping mechanism 20 located in the water tank 12, the water spray nozzle 13 can spray water onto the friction component 33 and the bezel 40 during grinding, achieving a cooling effect and preventing the bezel 40 of the belt sander from overheating.

[0051] The frame 10 is provided with a second driving member 14, which drives the water tank 12 and the clamping mechanism 20 located in the water tank 12 to move. By setting the second driving member 14, the water tank 12 and the clamping mechanism 20 located in the water tank 12 can be driven to move, thereby adjusting the position of the bezel 40 and improving the polishing accuracy and effect.

[0052] Specifically, the second driving component 14 drives a left-right driving module 141 and a front-back driving module 142. The left-right driving module 141 drives the water tank 12 to move left and right, and the front-back driving module 142 drives the left-right driving module 141 and the water tank 12 to move back and forth.

[0053] It should be noted that the first driving component 11 can also be configured to drive the clamping mechanism 20 to move up and down, and the friction component 33 can also be a grinding wheel.

[0054] The working principle of this utility model is as follows: The operator places the bezel 40 to be polished on the chuck 231. The cylinder 232 drives the chuck 231 to clamp the bezel 40, and the polishing assembly 32 is started. The friction element 33 rotates, and the first driving element 11 drives the polishing mechanism 30 to move down. After the friction element 33 moves down, it abuts against the upper surface of the bezel 40. At the same time, the left and right driving modules 141 drive the water tank 12 and the clamping mechanism 20 located in the water tank 12 to move left and right. The friction element 33 polishes the bezel 40 during the rotation. When the friction element 33 abuts against the first positioning block 25 or the second positioning block 26, the bezel 40 is polished in place. The front and rear driving modules 142 drive the left and right driving modules 141 and the water tank 12 to move backward and remove the polished bezel 40.

[0055] In summary, this utility model provides a clamping mechanism 20 consisting of a base 21, a second base 22, a clamping assembly 23, and a buffer spring. The second base 22 is slidably mounted on the base 21, the buffer spring is located between the second base 22 and the base 21, the clamping assembly 23 is mounted on the second base 22, and the friction element 33 is located in front of the clamping assembly 23. During operation, the buffer spring generates an elastic force along the vertical direction on the second base 22 and the clamping assembly 23, ensuring that the bezel 40 on the clamping assembly 23 and the friction element 33 maintain elastic contact along the vertical direction. This prevents excessive pressure from the friction element 33 on the bezel 40 during the polishing process, thus preventing damage to the bezel 40.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
