Description

Technical Field

[0001] The utility model relates to the technical field of watch processing, and more specifically to a fast positioning and punching device for producing quartz watches. Background Art

[0002] A quartz watch, also known as a quartz vibration electronic watch, is a type of wristwatch. The watch strap is an indispensable accessory of a watch. During the processing and manufacturing of a watch, a punching device is required to position and punch holes in the watch strap to facilitate subsequent users to wear it.

[0003] Based on the above, the inventors found that when the existing positioning and punching device is in use, the driving member drives the positioning plate to fix the watch strap, and then the punching device is pressed down to punch holes. After that, the punching device and the positioning plate are reset to replace the watch strap. Although it is convenient to use, the punching device is in a stopped state during the replacement of the watch strap, resulting in a waste of time. Therefore, in view of this, the existing structure is studied and improved, and a rapid positioning and punching device for quartz watch production is provided, in order to achieve a more practical purpose.

[0025] Embodiment:

[0026] Please refer to Figures 1-4, A quick positioning and punching device for quartz watch production, including a support frame 1. A cylinder 2 is fixedly connected to the upper middle part of the support frame 1. The output end of the cylinder 2 is fixedly connected to a punching plate 3. Two driving motors 4 are fixedly connected to one end of the support frame 1. The output end of the driving motor 4 is fixedly connected to a lead screw 5. A slider 6 is sleeved on the outer side of the lead screw 5. The opposite surfaces of the two sliders 6 are fixedly connected to a placement plate 7. A set of punching slots 8 are arranged through the middle of both ends of the placement plate 7. And two first clamping plates 9 and two second clamping plates 10 are symmetrically arranged at both ends of the placement plate 7 respectively. Tooth bars 11 are fixedly connected to the inner ends of the two first clamping plates 9 and the two second clamping plates 10. A toothed ring 12 is meshed and connected in the middle of the opposite surfaces of adjacent two tooth bars 11. A synchronous adjustment mechanism 13 is arranged on the top surface of the toothed ring 12. Start the driving motor 4, and the lead screw 5 cooperates with the slider 6 to drive the placement plate 7 to move, so that the clamped and fixed watchband is located directly below the punching plate 3.

[0027] Refer to Figure 3 , The synchronous adjustment mechanism 13 includes a two-way motor 14. The output end of the two-way motor 14 is fixedly connected to a first tooth block 15. A second tooth block 16 is meshed and connected to one side of the first tooth block 15. And anti-drop rings 17 are fixedly connected to the lower sides of the first tooth block 15 and the second tooth block 16 respectively. A set of ball bearings 18 are movably connected to the upper and lower sides of the anti-drop rings 17. In order to make the first clamping plate 9 and the second clamping plate 10 move synchronously and in opposite directions, the synchronous adjustment mechanism 13 is provided.

[0028] Refer to Figure 2 , Both ends of the placement plate 7 are symmetrically arranged. The punching plate 3 is adapted to the punching slots 8. The cylinder 2 drives the punching plate 3 to press down the watchband, and cooperates with the punching slots 8 to complete the punching work of the watchband. Then the cylinder 2 drives the punching plate 3 to reset, and the lead screw 5 cooperates with the slider 6 to drive the placement plate 7 to continue to move, so that the unpunched watchband is located directly below the punching plate 3.

[0029] Refer to Figure 3 , Both the first clamping plate 9 and the second clamping plate 10 are slidably connected to the placement plate 7. And clamping slots are opened at the inner sides of the tops of the first clamping plate 9 and the second clamping plate 10. The toothed ring 12 on the bottom surface of the first tooth block 15 cooperates with the tooth bar 11 at one end of the first clamping plate 9, so that the two first clamping plates 9 move synchronously towards the inner side to clamp and fix the corresponding watchband.

[0030] Refer to Figure 3 The two-way motor 14 is fixedly connected to the bottom surface of the placement plate 7. Both the first tooth block 15 and the second tooth block 16 are movably connected to the top surface of the placement plate 7. Start the two-way motor 14, and the first tooth block 15 cooperates with the second tooth block 16 to make the two toothed rings 12 rotate synchronously.

[0031] Refer to Figure 4, the two toothed rings 12 are respectively fixedly connected to the bottom surfaces of the first toothed block 15 and the second toothed block 16. When the first toothed block 15 drives the corresponding toothed ring 12 to rotate, the second toothed block 16 drives the corresponding toothed ring 12 to rotate in the opposite direction.

[0032] Refer to Figure 4 , the anti - detachment ring 17 is movably connected to the inside of the placement plate 7. One side of the ball 18 is in contact with the inner surface of the placement plate 7. During the rotation of the first toothed block 15 and the second toothed block 16, the anti - detachment ring 17 ensures the rotational stability, and the ball 18 reduces the rotational friction force to reduce the occurrence of accidents.

[0033] During use: The whole positioning and punching device's main body is composed of the support frame 1, the punching plate 3, the placement plate 7, the first clamping plate 9, the second clamping plate 10 and the synchronous adjustment mechanism 13. In daily work, place the first watchband at one end of the placement plate 7 close to the first clamping plate 9, start the bidirectional motor 14. The first toothed block 15 cooperates with the second toothed block 16, and the toothed ring 12 on the bottom surface of the first toothed block 15 cooperates with the toothed rod 11 at one end of the first clamping plate 9, so that the two first clamping plates 9 move synchronously inward to clamp and fix the corresponding watchband. The toothed ring 12 on the bottom surface of the second toothed block 16 cooperates with the toothed rod 11 at one end of the second clamping plate 10, so that the two second clamping plates 10 move synchronously outward, and at the same time place the second watchband at one end of the placement plate 7 close to the second clamping plate 10. Then start the drive motor 4, and the lead screw 5 cooperates with the slider 6 to drive the placement plate 7 to move, so that the clamped and fixed watchband is located directly below the punching plate 3. The air cylinder 2 drives the punching plate 3 to press down on the watchband, and cooperate with the punching slot 8 to complete the punching work of the watchband. Then the air cylinder 2 drives the punching plate 3 to reset, and the lead screw 5 cooperates with the slider 6 to drive the placement plate 7 to continue to move, so that the unpunched watchband is located directly below the punching plate 3. At this time, the bidirectional motor 14 rotates in the reverse direction, so that the two first clamping plates 9 move synchronously outward to release the watchband that has completed the punching process and replace it with a new one. At the same time, the two second clamping plates 10 move synchronously inward to clamp and fix the unpunched watchband, and then continue the punching work through the punching plate 3. And during the rotation of the first toothed block 15 and the second toothed block 16, the anti - detachment ring 17 ensures the rotational stability, and the ball 18 reduces the rotational friction force to reduce the occurrence of accidents.
