Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a metal watch case surface wire drawing device. Background Technology

[0002] Brushing is a common metal surface treatment process that aims to create specific line patterns on the metal surface through mechanical means. This process not only enhances the aesthetic appearance of the product but also improves its wear resistance and scratch resistance. It is widely used in watchmaking, jewelry, electronic product casings, and other fields.

[0003] When brushing the surface of a metal watch case, it can usually be placed directly in the designated position for processing. However, when brushing multiple surfaces or beveled surfaces, the operator needs to manually flip or hold the watch case to adjust the angle. This method is inefficient and can easily lead to inaccurate positioning and unstable brushing quality.

[0004] To address the existing problems, there is a need to provide a metal watch case surface brushing device that facilitates the adjustment of the angle of the metal watch case. Utility Model Content

[0005] To overcome the drawback of needing to hold the watch case by hand when brushing the beveled surface, this utility model provides a metal watch case surface brushing device.

[0006] The technical solution of this utility model is as follows: a metal case surface brushing device, including a frame, a brushing assembly, and a first connecting plate. The brushing assembly is provided inside the frame, and the first connecting plate is connected inside the frame. It also includes sliding blocks, a second connecting plate, a damping shaft, a second mounting plate, a second lead screw, a threaded sleeve, a belt, a second guide rod, a fixing block, and a fixing plate. Sliding blocks are symmetrically slidably connected to the front and rear of the first connecting plate. The second connecting plate is symmetrically connected to the left and right between the two sliding blocks. The damping shaft is rotatably connected to the inner side of the two first connecting plates. The second mounting plate is installed at the rear end of the damping shaft on the front side. The second lead screw is symmetrically slidably connected to the left and right of the second mounting plate. The threaded sleeve is symmetrically rotatably connected to the front side of the second mounting plate. The second lead screw is threadedly connected to the threaded sleeve. A belt is wound between the two threaded sleeves. The second guide rod is symmetrically slidably connected to the left and right of the second mounting plate. The second guide rod and the rear end of the second lead screw on the same side are fixedly connected to the fixing block. The front end of the damping shaft on the rear side is connected to the fixing plate.

[0007] As an improvement to the above solution, the wire drawing assembly also includes a first guide rod, a first lead screw, a first motor, a lifting plate, an electric slide rail, a slider, a first mounting plate, a second motor, and a wire drawing roller. The first guide rod is connected to the left side inside the frame, and the first lead screw is rotatably connected to the right side inside the frame. The first motor is installed on the right side inside the frame, and the output shaft of the first motor is connected to the first lead screw. The lifting plate is threaded onto the first lead screw, and the lifting plate is slidably connected to the first guide rod. An electric slide rail is installed on the lifting plate, and a slider is slidably connected to the electric slide rail. The first mounting plates are symmetrically connected to the slider, and the second motor is installed on the rear side of the rear first mounting plate. A wire drawing roller is rotatably connected between the two first mounting plates, and the output shaft of the second motor passes through the first mounting plate and is fixedly connected to the wire drawing roller.

[0008] As an improvement to the above solution, it also includes a connecting ring, a third connecting plate, a sliding rod, a limiting block, and a spring. The connecting ring is connected to the damping shaft on the front side. Multiple fixing grooves are evenly spaced on the connecting ring. The third connecting plate is connected to the sliding block on the front side. The sliding block is slidably connected inside the third connecting plate. The bottom of the sliding block is connected to a limiting block. The limiting block is engaged with the fixing groove. A spring is connected between the limiting block and the top of the third connecting plate.

[0009] As an improvement to the above solution, a connecting sleeve is also included, with the front sides of both threaded sleeves connected to the connecting sleeve.

[0010] As an improvement to the above solution, a pull rod is also included, with the top of the sliding rod connected to the pull rod.

[0011] As an improvement to the above solution, a sponge pad is also included, with sponge pads installed on both the rear side of the fixing block and the front side of the fixing plate.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a first connecting plate, a sliding block, a second connecting plate, a damping shaft, a second mounting plate, a second lead screw, a threaded sleeve, a belt, a second guide rod, a fixing block, and a fixing plate, this device can stably place the metal watch case between two second connecting plates and securely fix it using the fixing block. In addition, with the help of the rotation function of the damping shaft, the metal watch case can be flexibly and accurately adjusted to any required angle, which not only improves the operating efficiency but also avoids the problems of inaccurate positioning and unstable wire drawing quality that may occur during manual adjustment. This ensures the accuracy of the processing process and the consistency of the surface treatment quality. In this way, whether processing a single plane or multiple inclined planes, it can be completed efficiently, greatly improving the flexibility of work and production efficiency.

[0013] 2. By setting up a connecting ring, a third connecting plate, a sliding rod, a limiting block, and a spring, this device can effectively limit the connecting ring using the limiting block, thereby achieving a stable fixation of the damping shaft. This ensures that the position of the damping shaft is precisely controlled during operation, avoiding unnecessary movement or rotation, thus improving the stability of the overall structure and the accuracy of operation.

The wire drawing assembly is located inside the frame 1. The wire drawing assembly also includes a first guide rod 2, a first lead screw 3, a first motor 4, a lifting plate 5, an electric slide rail 6, a slider 7, a first mounting plate 8, a second motor 9, and a wire drawing roller 10. The first guide rod 2 is connected to the left side of the inside of the frame 1, and protrusions are provided on both the upper and lower sides of the right side of the inside of the frame 1. A first lead screw 3 is rotatably connected between two protrusions. A first motor 4 is installed on the right side inside the frame 1. The output shaft of the first motor 4 passes through the upper protrusion and is connected to the first lead screw 3. A lifting plate 5 is threaded onto the first lead screw 3. The lifting plate 5 is slidably connected to the first guide rod 2. An electric slide rail 6 is installed on the lifting plate 5, which can drive the wire drawing roller 10 to move left and right. A slider 7 is slidably connected to the electric slide rail 6. A first mounting plate 8 is symmetrically connected to the slider 7. A second motor 9 is installed on the rear side of the first mounting plate 8. A wire drawing roller 10 is rotatably connected between the two first mounting plates 8 for wire drawing the metal case. The output shaft of the second motor 9 passes through the first mounting plate 8 and is fixedly connected to the wire drawing roller 10. A first connecting plate 11 is connected inside the frame 1. Sliding blocks 12 are symmetrically slidably connected to the front and rear of the connecting plate 11. A second connecting plate 13 is symmetrically connected between the two sliding blocks 12. A damping shaft 14 is rotatably connected to the inner sides of the two first connecting plates 11, which can be used to drive the metal case to rotate. A second mounting plate 15 is installed at the rear end of the damping shaft 14 on the front side. A second lead screw 16 is symmetrically slidably connected to the second mounting plate 15. A threaded sleeve 1601 is symmetrically rotatably connected to the front side of the second mounting plate 15. The second lead screw 16 is threadedly connected to the threaded sleeve 1601. A belt 1602 is wound between the two threaded sleeves 1601, allowing the two threaded sleeves 1601 to rotate synchronously. A second guide rod 17 is symmetrically slidably connected to the second mounting plate 15 on the left and right sides. A fixing block 18 is fixedly connected between the rear end of rod 17 and the rear end of the second lead screw 16 to fix the metal watch case. A fixing plate 19 is connected to the front end of the rear damping shaft 14, and a connecting ring 21 is connected to the front damping shaft 14. Multiple fixing grooves 2101 are evenly spaced on the outer ring of the connecting ring 21. A third connecting plate 22 is connected to the front sliding block 12, and a sliding block 12 is slidably connected inside the third connecting plate 22. A limit block 24 is connected to the bottom of the sliding block 12, and the limit block 24 engages with the fixing groove 2101 to limit the connection ring 21. A spring 25 is connected between the limit block 24 and the top of the third connecting plate 22. A connecting sleeve 20 is connected to the front side of both threaded sleeves 1601 to facilitate the rotation of the threaded sleeves 1601.A pull rod 26 is connected to the top of the sliding rod 23 for easy pulling. Sponge pads 27 are installed on the rear side of the fixing block 18 and the front side of the fixing plate 19 to protect the surface of the metal case.

[0022] When it is necessary to brush the metal watch case, the operator first pushes the sliding block 12 to the left, causing all the connected parts to move. Once the sliding block 12 reaches the appropriate position, the operator stops pushing. Then, the operator places the metal watch case to be brushed on the first connecting plate 11 between the two sliding blocks 12, ensuring it contacts the front side of the fixed plate 19. Next, the operator rotates the connecting cylinder 20, which causes the threaded sleeve 1601 to rotate. The rotation of the threaded sleeve 1601 causes the second lead screw 16 to move inward. Simultaneously, the threaded sleeve 1601 drives another threaded sleeve 1601 to rotate via the belt 1602, causing the two leads to... The second lead screw 16 moves inward synchronously, which will drive the fixed block 18 and the two second guide rods 17 to move inward. After the fixed block 18 contacts and fixes the metal casing, the rotating connecting cylinder 20 stops. Then, the operator pushes the sliding block 12 again to move it to the middle position of the first connecting plate 11. Next, the second motor 9 is started. The output shaft of the second motor 9 drives the wire drawing roller 10 to rotate. Then the first motor 4 is started. The output shaft of the first motor 4 drives the first lead screw 3 to rotate, causing the lifting plate 5 to descend along the first guide rod 2. The lifting plate 5 drives all the components on it to move together. When the bottom of the wire drawing roller 10 moves to the top of the metal casing and contacts it, the first lead screw 16 is closed. First motor 4 is started, then electric slide rail 6 is activated. Electric slide rail 6 drives slider 7 to move back and forth, thereby causing wire drawing roller 10 to draw the metal case. After drawing is completed, second motor 9 and electric slide rail 6 are turned off, and first motor 4 is restarted. The motor output shaft drives first lead screw 3 to reverse, causing lifting plate 5 to rise to a suitable position before turning off first motor 4. If it is necessary to draw the other side of the metal case, the operator needs to pull the pull rod 26 upward. Pull rod 26 drives sliding block 12 and limit block 24 to move upward. Spring 25 is compressed, causing limit block 24 to disengage from the fixed groove 2101. At this time, the operator can rotate the metal case to... At a specified angle, the metal case drives the two damping shafts 14 to rotate. After rotation, the pull rod 26 is released, the spring 25 returns to its original position, and the sliding rod 23 and the limiting block 24 return to their original positions and re-engage in the fixing groove 2101, thus completing the limiting of the damping shaft 14. The first motor 4, the second motor 9, and the electric slide rail 6 are restarted, so that the wire drawing roller 10 continues to draw the metal case. After the entire wire drawing process is completed, the operator pushes the sliding block 12 back to its initial position to the left and stops pushing the sliding block 12. Finally, the connecting cylinder 20 is reversed, so that the two second lead screws 16 move in opposite directions, releasing the fixation of the metal case, removing the metal case, and completing the entire wire drawing operation.
