Description

Technical Field

[0001] This utility model relates to the field of watch case processing technology, specifically a small chamfering and deburring device for watch cases. Background Technology

[0002] The watch case is the main outer casing of a watch, its primary function being to protect the internal precision components (such as the movement, dial, and hands), and it is closely connected to other components such as the crystal, case back, and crown. It directly affects the watch's water resistance, dust resistance, and antimagnetic properties, and also determines its overall design style.

[0003] After chamfering, existing watch cases require deburring at the chamfered edges. Different watch case shapes require different fixing devices, necessitating frequent device changes during processing. This increases equipment downtime and significantly reduces overall deburring efficiency. Furthermore, deburring generates metal shavings that accumulate in the device and cannot be cleaned promptly, resulting in a cluttered upper area. This not only affects the cleanliness of the working environment but can also, over time, impact the device's positioning accuracy and ease of operation.

[0004] Therefore, those skilled in the art have provided a small chamfering and deburring device for watch cases to solve the problems mentioned in the background art, which require different fixing devices for different shaped watch cases. When processing watch cases of different shapes, it is necessary to frequently change the fixing devices, which increases the downtime of the equipment and significantly reduces the overall deburring efficiency.

[0028] Example 1:

[0029] Please see Figure 1-4 A small chamfering and deburring device for watch cases, comprising:

[0030] The outer shell 1 has a drop rail 2 fixedly installed at the lower end of the inner side of the outer shell 1. The lower end of the drop rail 2 has a fixed installation groove 3. A collection box 4 is fixedly connected inside the installation groove 3. An air pump 5 is fixedly installed at the top of the outer shell 1. An air supply pipe 6 is fixedly installed at the upper end of the air pump 5. A bracket 7 is fixedly installed on the outside of the air supply pipe 6. An air distribution strip 8 is fixedly installed at the lower end of the air supply pipe 6. An air jet pipe 9 is fixedly installed at the upper end of the air distribution strip 8.

[0031] A vertical moving rod 10 is fixedly installed on both sides of the inner wall of the outer casing 1. A telescopic rod 11 is fixedly installed inside the vertical moving rod 10, and a first sliding block 12 is installed on the upper right side of the telescopic rod 11.

[0032] A transverse moving rod 13 is provided, and a telescopic rod 14 is fixedly installed inside the transverse moving rod 13. A second sliding block 15 is fixedly installed at the front of the upper end of the telescopic rod 14, and a lifting rod 16 is fixedly installed at the lower end of the second sliding block 15. A hollow rod 17 is fixedly installed at the lower end of the lifting rod 16, and holes 18 are fixedly opened on the upper and lower sides of the inner wall of the hollow rod 17. A through rod 19 is inserted and connected inside the hollow rod 17, and a hole 20 is opened at the upper end of the through rod 19. A grinding block 21 is fixedly installed at the lower end of the through rod 19, and a bolt 22 is fixedly installed inside the hole 20.

[0033] On both sides of the inner wall of the outer shell 1, connecting grooves are fixedly opened. The falling bin 2 is a detachable structure, and the collection box 4 is a detachable structure. The air delivery pipes 6 are symmetrically installed on the front and rear sides of the air pump 5 with the air pump 5 as the central reference.

[0034] The inner side of the bracket 7 is connected to the outer end face of the outer shell 1. The air distribution strip 8 is fixedly installed in the connecting groove in the outer shell 1. The air injection pipe 9 is a downward inclined structure. The vertical moving rod 10 is symmetrically installed on the front and rear sides of the outer shell 1 with the upper end inside the outer shell 1 as the central reference.

[0035] The second sliding block 15 has the same structure as the first sliding block 12. The second sliding block 15 is in the shape of the Chinese character 'tu'. The holes 18 are symmetrically installed on the front and rear sides of the hollow rod 17 with the hollow rod 17 as the central reference. The holes 18 are aligned and connected with the holes 20. The second sliding block 15 forms a sliding connection with the groove of the transverse moving rod 13 through the second telescopic rod 14.

[0036] In this embodiment, the watch case to be processed is firmly clamped on the workstation. The PLC controller starts the equipment system and activates the displacement sensor (used to acquire the watch case position information). The displacement sensor is FCNA19. The displacement sensor detects the position of the watch case and feeds back the position signal to the PLC. The PLC controls the telescopic rod 11 inside the vertical moving rod 10 to move. The telescopic rod 11 drives the first sliding block 12 connected to it to slide along the groove of the vertical moving rod 10, realizing the longitudinal position adjustment of the horizontal moving rod 13. The PLC controls the telescopic rod 24 inside the horizontal moving rod 13 to move. The telescopic rod 214 drives the second sliding block 15 connected to it to move. The second sliding block 15 drives the lifting rod 16 connected to it to move vertically. The lifting rod 16 finally drives the polishing execution head (rotating rod and polishing block 21) at its lower end to move precisely to the position of the watch case burr and adjusts the polishing block 21 to a suitable working height. The rotating rod at the lower end of the lifting rod 16 is activated, driving the polishing block 21 to rotate at high speed. The grinding block 21 polishes and removes burrs from the positioned watch case. When it is necessary to replace the worn or different type of grinding block 21, remove and pull out the bolt 22 that passes through hole 18 (located on the hollow rod 17) and hole 20 (located on the insert rod 19). Pull down the insert rod 19 to remove it from the hollow rod 17. At this time, the grinding block 21 installed at the end of the insert rod 19 can be replaced. After replacement, reverse the steps, insert the insert rod 19, align it with the hole of the hollow rod 17, insert and tighten. Secure bolt 22 and reassemble. Grinding debris falls downward through the grid-type drop bar 2 inside the equipment housing 1. At the same time, the PLC starts the air pump 5. The compressed gas generated by the air pump 5 is delivered to the air distribution bar 8 through the air supply pipe 6. Multiple downward-sloping jet pipes 9 are installed at the upper end of the air distribution bar 8. The jet pipes 9 spray gas downward to blow away the residual debris on the surface of the grid-type drop bar 2 and ensure that it falls smoothly. A debris collection box 4 is installed directly below the drop bar 2, where the grinding debris is finally collected and stored.

[0037] Example 2:

[0038] Please see Figure 5-6 This embodiment provides a technical solution based on Embodiment 1:

[0039] A fixed plate 23 is fixedly installed below the transverse moving rod 13. A sliding groove 24 is fixedly installed at the front of the upper end of the fixed plate 23. A hydraulic rod 25 is fixedly installed inside the sliding groove 24. Moving plates 26 are fixed on both sides of the hydraulic rod 25. A push rod 27 is fixedly installed at the front end of the moving plate 26. A clamping block 28 is fixedly installed at the front end of the push rod 27. A push rod 29 is fixedly installed inside the push rod 27. A clamping plate 30 is fixedly installed at the front end of the push rod 29. A through hole 31 is fixedly opened inside the clamping plate 30.

[0040] The movable plate 26 is symmetrically installed on the left and right sides of the hydraulic rod 25 with the hydraulic rod 25 as the center reference. The movable plate 26 is L-shaped. The push rod 27 is symmetrically installed on the left and right sides of the push rod 29 with the push rod 29 as the center reference. There are two through holes 31.

[0041] In this embodiment, the round or rectangular watch case to be clamped is placed in the inner positioning area of ​​the clamping structure. The controller activates the hydraulic rod 25, driving the two moving plates 26 to move towards the center. The moving plates 26 drive the connected push rod 27 to move towards the center. The push rod 27 pushes the arc-shaped clamping block 28 at its front end to move forward. The arc-shaped clamping block 28 passes through the through hole 31 of the clamping plate 30. The through hole 31 is wider than the clamping block 28. The arc-shaped front ends of the two opposing arc-shaped clamping blocks 28 contact and fit the outline of the round watch case. At the same time, the clamping plate 30 provides support, and together they clamp and fix the watch case. By adjusting the stroke of the hydraulic rod 25 to change the position of the moving plate 26, the distance between the two arc-shaped clamping blocks 28 can be adjusted to accommodate round watch cases of different diameters. The controller activates the push rod 29, which drives the cuboid clamping plate 30 to move towards the center. The two opposing cuboid clamping plates 30 contact the side of the rectangular watch case and clamp and fix it.

[0042] The working principle of this utility model is as follows: The watch case is placed inside the clamping plate 30. The corresponding push rod is selected and activated according to the shape of the watch case (round or rectangular). When clamping a round watch case, the controller activates push rod 27, which drives the arc-shaped clamping block 28. The arc-shaped clamping block 28 passes through the through hole 31 on the clamping plate 30. The arc-shaped surface formed by the arc-shaped clamping block 28 and the clamping plate 30 clamps and fixes the round watch case. When clamping a rectangular watch case, the push rod is directly... Pushing lever 29 causes clamping plate 30 to clamp and fix the rectangular watch case. This activates telescopic lever 11 inside vertical moving lever 10, causing first sliding block 12 to slide within the groove of vertical moving lever 10, thereby adjusting the height of horizontal moving lever 13. Then, telescopic lever 14 inside horizontal moving lever 13 is activated, causing second sliding block 15 to adjust the horizontal position of lifting lever 16. Finally, lifting lever 16 is activated, adjusting the bottom polishing block 21. The watch case is raised to a suitable height. A rotating rod is installed at the bottom of the lifting rod 16, driving the rotating rod to rotate the polishing block 21, thus polishing the watch case. The polishing debris falls onto the drop rail 2 and enters the collection box 4 in the mounting groove 3 below it. The air pump 5 is activated, generating gas which is delivered through the air supply pipe 6 to the jet pipe 9 on the air distribution bar 8. The jet pipe 9 is designed with a downward tilt, using the ejected gas to clean the debris remaining on the drop rail 2, concentrating the debris... In the collection box 4, the worker unscrews the bolt 22 that fixes the grinding block 21 to the bottom of the insert rod 19 (the bolt 22 passes through hole 18 and hole 20), pulls down the insert rod 19 connected to the grinding block 21, and completely pulls the insert rod 19 out of the hollow rod 17 at the bottom of the lifting rod 16. The old grinding block 21 can then be removed. When installing the new grinding block 21, the worker follows the reverse steps to insert the insert rod 19 of the new grinding structure into the hollow rod 17, aligns the hole 18 and hole 20, inserts and tightens the bolt 22.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
