Description

Technical Field

[0001] This utility model belongs to the technical field of watch clamps, specifically a watch frame flip-type polishing clamp. Background Technology

[0002] The watch bezel is an important component of the watch case, typically located in the middle section, connecting the bezel, case back, and crystal. Its main function is to support and protect the internal structure, including the movement and dial, while also affecting the watch's overall appearance and water resistance. The bezel is usually made of metal, and its machining precision directly determines the case's sealing performance. It typically requires surface treatments such as polishing to meet both aesthetic and functional requirements.

[0003] Polishing the outer ring wall and the edge of the outer ring wall is a common process in the processing of clock frames. When processing the clock frame, it is necessary to fix the clock frame first. Existing fixtures, such as the "Adjustable Clock Fixture" disclosed in patent document "CN221390652U", have the technical solution of placing the clock between two clamping plates 9 and fixing it by rotating the fixing screw 7 with the adjusting head 8.

[0004] In this patent, the clock frame is held in place by two clamping plates. Although this can fix the clock frame, it is difficult to polish the outer ring wall and its edges because the clamping plates directly abut against the outer ring wall of the clock frame. Utility Model Content

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please refer to Figure 1-7 ;

[0029] This utility model discloses a clock frame flip-type polishing fixture for clamping the clock frame. Figure 1 The present invention discloses the structure of a clock frame. In order to achieve grinding of the outer ring wall and the edge of the outer ring wall of the clock frame, the flip-type grinding fixture includes a support column 1 and a nested column 2. The bottom surface of the nested column 2 is fixedly connected to the upper surface of the support column 1. The outer diameter of the support column 1 is larger than the outer diameter of the nested column 2. The nested column 2 is used to pass through the inner ring of the clock frame. The upper surface of the support column 1 is used to support the clock frame. A fixing cylinder 3 is provided on the nested column 2. The inner wall of the fixing cylinder 3 is rotatably connected to the outer wall of the nested column 2. The bottom surface of the fixing cylinder 3 and the upper surface of the support column 1 are provided with a gap for clamping the clock frame.

[0030] Specifically, when clamping the clock frame, the operator first rotates the fixing cylinder 3 and the nesting post 2 in opposite directions to remove the fixing cylinder 3 from the nesting post 2. Then, the inner ring of the clock frame passes through the nesting post 2 until the bottom surface of the clock frame abuts against the upper surface of the support post 1. After that, the fixing cylinder 3 is placed on the nesting post 2, and the fixing cylinder 3 is rotated so that the bottom surface of the fixing cylinder 3 abuts against the upper surface of the clock frame. The clock frame is then clamped by the bottom surface of the fixing cylinder 3 and the upper surface of the support post 1, thus fixing the clock frame. At this time, the operator can use a grinding tool to grind the outer ring wall and the edge of the outer ring wall of the clock frame, thereby enabling the clock frame to meet more application needs in various scenarios.

[0031] In this embodiment, a groove 4 is provided on the outer wall of the supporting column 1. The groove opening of the groove 4 is horizontal. A slider 5 is provided at the bottom of the groove 4. The slider 5 is slidably connected to the bottom of the groove 4 in the vertical direction. A spring 6 is provided on the lower groove wall of the groove 4. One end of the spring 6 is fixedly connected to the lower groove wall of the groove 4, and the other end of the spring 6 is fixedly connected to the lower surface of the slider 5. A clamping part 7 is fixedly provided at the end of the slider 5 away from the groove 4. The clamping part 7 can move up and down and is used to fix the clock frame. Furthermore, the groove opening area of ​​the groove 4 is smaller than the groove bottom area of ​​the groove 4, and the surface of the slider 5 located inside the groove 4 abuts against the groove wall of the groove 4.

[0032] Specifically, when the operator places the clock frame on the upper surface of the support column 1, the clamping part 7 engages with the clock frame, further fixing the clock frame. It is worth noting that in this embodiment, the side wall of the clamping part 7 is an inclined wall, and the area of ​​the upper surface of the clamping part 7 is smaller than the area of ​​the lower surface. The operator can first press the spring 6 down to the bottom, thereby moving the clamping part 7 down to the lowest point. Then, the clock frame is clamped between the support column 1 and the fixing cylinder 3. Then, the spring 6 is released, and the spring 6 stretches under the action of elasticity, moving the slider 5 upward, thereby moving the clamping part 7 through the lug of the clock frame. The lug of the clock frame is inserted into the clamping part 7, thereby fixing the clock frame. By setting the spring 6, the clamping part 7 can be applied to clock frames with different lug sizes.

[0033] In this embodiment, the inner wall of the fixed cylinder 3 is provided with internal threads, and the outer wall of the nested column 2 is provided with external threads. The inner wall of the fixed cylinder 3 is threadedly connected to the outer wall of the nested column 2.

[0034] In this embodiment, a base plate 8 and a support plate 9 are also included. The support plate 9 is vertically arranged, and the base plate 8 and the support plate 9 are fixedly connected. A first rotating column 10 and a second rotating column 11 are provided on the support plate 9. The first rotating column 10 can be inserted into the fixed cylinder 3 and the nested column 2, and the second rotating column 11 is fixedly connected to the bearing column 1. The first rotating column 10 and the second rotating column 11 can rotate relative to the support plate 9. Further, the first rotating column 10 includes a cylindrical part 101 and a cylindrical part 102. One end of part 102 is located inside cylindrical part 101, and cylindrical part 102 and cylindrical part 101 are slidably connected in the horizontal direction. A clearance hole 12 is provided in the length direction of cylindrical part 101. A toggle block 13 is fixedly provided in cylindrical part 102. The toggle block 13 passes through clearance hole 12 and is slidably connected to the hole wall of clearance hole 12. Fixed cylinder 3 and nested column 2 are provided with insertion hole one and insertion hole two. Cylindrical part 102 is inserted into insertion hole one and insertion hole two.

[0035] Specifically, the operator first mounts rotating column 10 and rotating column 2 11 on the support plate 9, allowing them to rotate freely. Then, the clock frame is placed on the support column 1 and its position is adjusted to ensure stability. The operator can then control the sliding of the cylindrical part 102 within the cylindrical part 101 by moving the toggle block 13, moving the cylindrical part 102 toward the fixed cylinder 3. This allows the cylindrical part 102 to pass through insertion hole 1 and insertion hole 2, thus connecting the cylindrical part 102 with insertion hole 1 and insertion hole 2. This achieves the clamping and support of the support column 1, nested column 2, and fixed cylinder 3 by rotating rotating column 10 and rotating column 2 11. The operator can then rotate the support column 1, nested column 2, and fixed cylinder 3, thereby flipping the clock frame to better polish the outer ring wall and its edges.

[0036] In this embodiment, a pair of arc-shaped holes 14 are provided through the support plate 9. Rotating column one 10 and rotating column two 11 pass through the two arc-shaped holes 14 respectively. Rotating column one 10 and rotating column two 11 are rotatably connected to the support plate 9 through the arc-shaped holes 14. One end of rotating column one 10 passing through the support plate 9 and one end of rotating column two 11 passing through the support plate 9 are fixedly connected by a connecting plate 15. The connecting plate 15 is provided with a driving device, which is used to drive the connecting plate 15 to rotate. In this embodiment, the driving device includes a stepper motor 16, and the output shaft of the stepper motor 16 is coaxially connected to the center position of the connecting block.

[0037] In this embodiment, a load-bearing part 17 is provided on the base plate 8, and the upper end of the load-bearing part 17 is arc-shaped.
