A second inclined groove is formed on the upper surface of the second gear disk. Moving pins are provided inside both the first and second inclined grooves. A limiting pin is fixedly connected to the upper surface of the moving pin, and a clamping member is fixedly connected to the upper surface of the limiting pin. A first moving groove is formed on the inner surface of the first rotating groove on the right side. A first lead screw is movably mounted on the inner wall of the first moving groove. A throttle is fixedly connected to one end of the first lead screw. A moving strip is threadedly connected to the outer surface of the first lead screw. Multiple toothed grooves are formed on the side wall of the moving strip, and these toothed grooves mesh with the first gear disk on the right side.

[0006] Preferably, the sidewall of the clamping member is fixedly connected with a friction pad, and a second moving groove is provided at the top inner part of the first rotating groove. There are multiple second moving grooves, and the limiting pin is located inside the second moving groove.

[0008] Preferably, a first rotating shaft is movably mounted on the inner surface of the second rotating groove, one end of the first rotating shaft is fixedly connected to a pulley, and a belt is movably sleeved on the outer wall of the adjacent pulley.

[0009] Preferably, a second shaft is fixedly connected to the end of the pulley away from the first shaft, and a first bevel gear is fixedly connected to the end of the second shaft away from the pulley.

[0010] Preferably, a second bevel gear is fixedly connected to the side of the first rotating shaft away from the pulley, a third rotating shaft is fixedly connected to the side wall of the second bevel gear on the left side, a motor is fixedly connected to the side wall of the operating table, and the output end of the motor is fixedly connected to the third rotating shaft.

[0011] Preferably, the lower surface of the operating table is fixedly connected with four fixed legs. The inner surface of the second rotating groove is provided with four third rotating grooves.

The outer wall of the extended support leg is fixedly connected with a limiting block, and there are multiple limiting blocks, which are located inside the limiting groove.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a clamp for quick clamping of watch cases, which has the following beneficial effects.

[0014] (1) Compared with the prior art, the quick-clamping fixture for the watch case comprises clamping components, a throttle, a first lead screw, a moving bar, a toothed groove, a first gear disc, a second gear disc, a first inclined groove, a second inclined groove, a moving pin, a limiting pin, and clamping components. When the watch case needs to be clamped and fixed, the watch case is placed between adjacent clamping components. Turning the throttle can drive the first lead screw to rotate, which in turn can drive the moving bar to move back and forth. When the moving bar moves forward, since the toothed groove meshes with the right first gear disc, it can drive the right first gear disc to rotate clockwise, which in turn can drive the second gear disc to rotate counterclockwise, which in turn can drive the left first gear disc to rotate clockwise. The movement, due to the presence of the first and second inclined grooves, can drive adjacent moving pins to move closer together, thus driving adjacent limiting pins and clamping parts to move closer together, thereby clamping and fixing the watch case through the clamping parts. When it is necessary to release the clamp, simply turn the throttle in the opposite direction. Compared with existing clamps, which often can only fix one watch case at a time when clamping and fixing a watch case, this quick-clamping watch case clamp can process multiple watch cases at the same time, reducing the number of clamping times, which can significantly improve production efficiency and reduce production costs.

[0015] (2) Compared with the prior art, the quick-clamping fixture for the watch case consists of an operating table, a motor, a third rotating shaft, a second bevel gear, a first rotating shaft, a pulley, a second rotating shaft, a first bevel gear, a belt, a third bevel gear, and an extension leg. When the height of the operating table needs to be controlled, the motor drives the third rotating shaft to rotate, which in turn drives the left second bevel gear and the first rotating shaft to rotate, which in turn drives the left pulley and the second rotating shaft and the first bevel gear to rotate, which in turn drives the belt and the right pulley to rotate, which in turn drives the right second rotating shaft and the first rotating shaft to rotate, which in turn drives the right first bevel gear and the second bevel gear to rotate. Therefore, the first bevel gears and the second bevel gears on both sides rotate synchronously, which can drive the four third bevel gears to rotate, thus controlling the extension leg to move downward, thereby increasing the overall height of the operating table.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Depend on Figures 1-9As shown, this utility model provides a quick-clamping fixture for watch cases, including an operating table 1. The operating table 1 has three first rotating grooves 2 inside. Two first gear disks 3 are movably mounted on the inner bottom of the first rotating grooves 2. Multiple first inclined grooves 4 are formed on the upper surface of the first gear disks 3. A second gear disk 5 is movably mounted on the inner bottom of the first rotating grooves 2, located between adjacent first gear disks 3. The second gear disk 5 meshes with the adjacent first gear disks 3 respectively. The upper surface of the second gear disk 5... A second inclined groove 6 is formed on the surface. A movable pin 7 is provided inside both the first inclined groove 4 and the second inclined groove 6. A limit pin 8 is fixedly connected to the upper surface of the movable pin 7, and a clamping member 9 is fixedly connected to the upper surface of the limit pin 8.

A handle 12 is fixedly connected to one end of the first lead screw 11. A movable strip 13 is threadedly connected to the outer surface of the first lead screw 11. Multiple toothed grooves 14 are formed on the side wall of the movable strip 13. The toothed grooves 14 are connected to the first gear disc 3 on the right side. When the watch case needs to be clamped and fixed, it is placed between adjacent clamping parts 9. Turning the handle 12 will drive the first lead screw 11 to rotate, which in turn will drive the moving bar 13 to move back and forth. When the moving bar 13 moves forward, since the tooth groove 14 meshes with the right first gear disk 3, it will drive the right first gear disk 3 to rotate clockwise, which will drive the second gear disk 5 to rotate counterclockwise, which will drive the left first gear disk 3 to rotate clockwise. Due to the presence of the first inclined groove 4 and the second inclined groove 6, the adjacent moving pins 7 can be moved closer to each other, so that... The adjacent limiting pins 8 and clamping parts 9 are brought closer together, and the watch case is clamped and fixed by the clamping parts 9. When it is necessary to release the clamp, simply turn the handle 12 in the opposite direction. The side wall of the clamping parts 9 is fixedly connected with friction pads 15, which can increase the friction between the clamping parts 9 and the watch case, making the clamping work easier. The inner top of the first rotating groove 2 is provided with a second moving groove 16. There are multiple second moving grooves 16. The limiting pins 8 are located inside the second moving grooves 16. The second moving grooves 16 and the limiting pins 8 cooperate with each other to limit the movement direction of the clamping parts 9.

[0028] Depend on Figures 1-9As shown, this utility model provides a quick-clamping fixture for watch cases. The operating table 1 has two second rotating grooves 17 inside. A first rotating shaft 18 is movably mounted on the inner surface of each second rotating groove 17. One end of the first rotating shaft 18 is fixedly connected to a pulley 19. A belt 20 is movably fitted onto the outer wall of an adjacent pulley 19. A second rotating shaft 21 is fixedly connected to the end of the pulley 19 away from the first rotating shaft 18. A first bevel gear 22 is fixedly connected to the end of the second rotating shaft 21 away from the pulley 19. A second bevel gear 23 is fixedly connected to the side of the first rotating shaft 18 away from the pulley 19. The left side of the second bevel gear 23... A third rotating shaft 24 is fixedly connected to the side wall of the control panel 3. A motor 25 is fixedly connected to the side wall of the control panel 1. The output end of the motor 25 is fixedly connected to the third rotating shaft 24. Fixed support legs 30 are fixedly connected to the lower surface of the control panel 1. Both the fixed support legs 30 and the extended support legs 29 can support the control panel 1. There are four fixed support legs 30. A third rotating groove 26 is opened on the inner surface of the second rotating groove 17. There are four third rotating grooves 26. A third bevel gear 27 is movably installed at the bottom of the inner surface of the third rotating groove 26. The front third bevel gear 27 meshes with the second bevel gear 23, and the rear third bevel gear 27 meshes with the first bevel gear 24. The two-phase meshing mechanism includes a second lead screw 28 fixedly connected to the lower surface of the third bevel gear 27. The thread direction of the second lead screw 28 is determined according to requirements. An extension leg 29 is threadedly connected to the outer surface of the second lead screw 28 and is located inside the fixed leg 30. When the height of the operating platform 1 needs to be controlled, the motor 25 drives the third rotating shaft 24 to rotate, which in turn drives the left second bevel gear 23 and the first rotating shaft 18 to rotate, which in turn drives the left pulley 19 and the second rotating shaft 21 and the first bevel gear 22 to rotate, which in turn drives the belt 20 and the right pulley 19 to rotate, which in turn drives the right second rotating shaft 21 and the first rotating shaft 18 to rotate. This causes the first bevel gear 22 and the second bevel gear 23 on the right side to rotate. Therefore, the first bevel gear 22 and the second bevel gear 23 on both the left and right sides rotate synchronously, which can drive the four third bevel gears 27 to rotate. This allows the extension leg 29 to move downward, thereby increasing the overall height of the operating table 1. The inner wall of the fixed leg 30 is provided with a limiting groove 31. There are multiple limiting grooves 31. The outer wall of the extension leg 29 is fixedly connected with a limiting block 32. The limiting groove 31 and the limiting block 32 cooperate to limit the movement of the extension leg 29. There are multiple limiting blocks 32, and the limiting blocks 32 are located inside the limiting groove 31.
