[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] refer to Figures 1-2As shown, the present invention provides a watch frame clamping device, comprising: an operating platform 1 with a plurality of clamping blocks 5 arranged in a circular array on the top, each clamping block 5 having a drill hole 15 extending from the outside to the inside, and an adjustment mechanism located at the center of the plurality of clamping blocks 5 in the operating platform 1, the adjustment mechanism being used to drive the plurality of clamping blocks 5 to expand outward or close inward, thereby clamping the plurality of clamping blocks 5 from the inside onto the inner wall of the watch in different directions based on the expansion.

[0021] Combination Figures 2-4 As shown, the adjustment mechanism includes a drive seat 9 and an electric push rod 12 arranged sequentially from top to bottom. The inner side of the bottom end of multiple clamping blocks 5 is inclined with a sloping edge 7, and the top of the drive seat 9 is provided with a frustum 8 that abuts against the sloping edge 7.

[0022] Combination Figure 2 As shown, the operating platform 1 has a lifting chamber 14 and an electrical compartment 13 arranged from top to bottom to accommodate the drive seat 9 and the electric push rod 12. Multiple moving slots 4 extending into the lifting chamber 14 are provided on the top of the operating platform 1 in multiple directions, and multiple clamping blocks 5 are respectively movably installed in the corresponding moving slots 4.

[0023] As described above, using the operating table 1, multiple clamping blocks 5, and adjustment mechanism provided by this utility model, the electric push rod 12 in the adjustment mechanism is installed inside the operating table 1 through the electrical compartment 13, the drive seat 9 is lifted and installed in the operating table 1 through the lifting compartment 14, and the clamping block 5 is moved and installed on the operating table 1 through the moving groove 4. At the same time, the top of the clamping block 5 extends to the top of the operating table 1. When the watch frame is placed on the operating table 1, the electric push rod 12 is activated, driving the lifting seat to rise, thereby abutting against the inclined side 7 through the truncated cone 8, and then driving the clamping block 5 to push outward in the moving groove 4. At this time, the watch frame can be clamped on the operating table 1. The hole punch is not shown in the figure. The hole punch is set outside the clamping block 5. When the hole punch punches the watch frame, the drill bit on the hole punch punches the watch frame. The drill bit passes through the clamping block 5 through the drill hole 15. At this time, the clamping block 5 supports the hole position of the watch frame.

[0024] In this utility model, combined with Figure 2 As shown, a pressure sensor 11 for clamping force detection is provided between the drive base 9 and the electric push rod 12 in this embodiment, and a mounting hole 10 for accommodating the pressure sensor 11 is provided at the bottom end of the drive base 9.

[0025] As described above, when using the pressure sensor 11 provided by this utility model, the pressure sensor 11 is installed between the drive seat 9 and the electric push rod 12 through the mounting hole 10. When the drive seat 9 is raised, it drives multiple clamping blocks 5 to push outward through the frustum 8. At this time, the multiple clamping blocks 5 clamp the watch frame, and the clamping force generated by the clamping acts on the pressure sensor 11. When the pressure sensor 11 detects that the force reaches the threshold, the pressure sensor 11 sends a feedback signal to the electric push rod 12 to stop the electric push rod 12 from driving, so as to avoid the clamping blocks 5 being over-clamped on the watch frame.

[0026] In this utility model, combined with Figures 1-2 As shown, each movable slot 4 in this embodiment is provided with a reset mechanism for driving the clamping block 5 to close and reset, and one end of the reset mechanism is installed on the outer wall of the clamping block 5.

[0027] Combination Figures 1-2 As shown, the reset mechanism includes a reset spring 2 and a guide rod 3. One end of the guide rod 3 is horizontally welded to the outer wall of the clamping block 5. A guide hole 6 is provided on the inner wall of the moving groove 4 to accommodate the extension and retraction of the guide rod 3. The reset spring 2 is sleeved on the guide rod 3, and the two ends of the reset spring 2 abut against the moving groove 4 and the clamping block 5 respectively.

[0028] As described above, when the drive seat 9 descends, the clamping block 5 releases the restriction of the frustum 8. At this time, the reset spring 2 is released, thereby driving the guide rod 3 to move outward in the guide hole 6, and then driving the clamping block 5 to close inward in the moving groove 4. At this time, the clamping block 5 releases the clamping of the watch frame.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
