Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to an integrated jig for clamping a watch case. Background Art

[0002] A watch case refers to the external protective shell of a watch. It wraps the movement and other components inside the watch. The watch case can prevent dust, moisture and physical damage from affecting the normal operation of the movement, provide a structural basis for fixing the dial, watch glass and watchband. The design and material of the watch case affect the appearance and style of the watch. The watch case usually consists of multiple parts, such as the watch case body, watch glass, back case and lugs. These parts together constitute the external structure of the watch.

[0003] Jigs play a crucial role in watch case processing. By improving processing accuracy, efficiency and safety, they help achieve high-quality processing results. Jigs can fix the watch case in a specific position, prevent errors caused by vibration or movement during processing, thereby improving processing accuracy. Jigs can ensure that the watch case always maintains the correct position and orientation during processing, which is crucial for achieving precision machining.

[0004] The existing jigs have complex structures and are not easy to disassemble. Impurities and fine chips generated during watch case processing easily enter the holes and grooves on the jigs. Long-term accumulation affects the accurate positioning of workpieces, resulting in processing errors. Moreover, the clamping method is relatively troublesome, affecting the clamping efficiency. Therefore, we propose an integrated jig for clamping a watch case to solve this problem. Summary of the Invention

Detailed implementation manners

[0025] In order to more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings.

[0026] Please refer to Figures 1 - 5 , an integrated fixture for clamping a watch case proposed by the present utility model includes a watch case 17, and includes two fixed frames 1. The tops of the two fixed frames 1 are fixedly installed with the same multi-station fixture 2. The multi-station fixture 2 includes a mounting plate 3 and a limit frame 4. The top of the mounting plate 3 is fixedly installed with a plurality of pallets 5. The plurality of pallets 5 are arranged in two rows at equal intervals. A plurality of square holes 6 are opened at the top of the limit frame 4. The limit frame 4 is placed on the top of the mounting plate 3. The pallet 5 is slidably connected to the corresponding square hole 6. The same first mounting groove 7 communicates between the left and right adjacent two square holes 6. A second mounting groove is opened on one side of the square holes 6 at the leftmost and rightmost sides. A plurality of clamping plates 8 are fixedly installed in the plurality of first mounting grooves 7 and the plurality of mounting grooves.

[0027] As Figure 2 shown, the same connecting plate 9 is fixedly installed between the two fixed frames 1. A plurality of threaded holes are opened at the bottom of the connecting plate 9. A plurality of threaded grooves adapted to the threaded holes are opened at the bottom of the mounting plate 3. The same bolt is threadedly connected in the threaded hole and the threaded groove.

[0028] As Figure 1As shown in the figure, a plurality of bases 11 are fixedly installed at the bottom of the mounting plate 3. A plurality of first oval holes 10 are formed at the top of the limiting frame 4. A plurality of round holes are formed at the top of the mounting plate 3. A screw rod is threadedly installed at the top of the base 11. The top end of the screw rod sequentially penetrates through the corresponding round hole and the first oval hole 10 and is fixedly installed with a nut 12.

[0029] As Figure 4 shown in the figure, second oval holes 13 are formed at the four corners of the top of the limiting frame 4. Positioning rods 14 are fixedly installed at the four corners of the top of the mounting plate 3. The positioning rods 14 are slidably connected in the corresponding second oval holes 13.

[0030] It should be noted that a plurality of support plates 5 are assembled to the mounting plate 3 by screws. Through the cooperation of the threaded holes on the connecting plate 9 and the threaded grooves on the mounting plate 3, the connecting plate 9 and the mounting plate 3 are fixedly assembled. Then, the limiting frame 4 is sleeved outside the plurality of positioning rods 14, so that the inner wall of the second oval hole 13 abuts against the positioning rod 14 for positioning the limit. The bottom ends of the plurality of screw rods penetrate through the first oval hole 10 and the round hole and then are screwed into the base 11, so that the nut 12 tightly abuts against the top of the limiting frame 4. Through the cooperation of the plurality of screw rods and the nut 12, the limiting frame 4 and the mounting plate 3 are locked, and the assembly of the whole device is completed.

[0031] As Figure 1 shown in the figure, cylinders 15 are fixedly installed on both the left and right sides of the mounting plate 3. Claws 16 are fixedly installed at the top ends of the cylinders 15.

[0032] It should be noted that the limiting frame 4 and the mounting plate 3 are locked through the cooperation of the plurality of screw rods and the nut 12 to provide long-term stable mechanical fixation. The cooperation of the cylinder 15 and the claw 16 can increase the additional clamping force to ensure that the plate does not move or vibrate during the fixation process. The cooperation of the cylinder 15 and the claw 16 can provide precise clamping force and position control to ensure the alignment and accurate position of the plate during fixation. The cooperation of the cylinder 15 and the claw 16 can quickly adjust the clamping force to adapt to plates of different thicknesses or materials, while the bolts provide the final firm fixation.

[0033] As Figure 5 shown in the figure, two arc-shaped holes 18 are formed on the outer side of the watch case 17. The clamping plate 8 is movably clamped in the corresponding arc-shaped holes 18.

[0034] As Figure 4 shown in the figure, two internal slots are formed at the top of the support plate 5. Spring pins 19 are fixedly installed in the internal slots. Two through holes 20 are formed on the watch case 17. The spring pins 19 are adapted to the through holes 20.

[0035] The top of the pallet 5 is provided with a wear-resistant coating, and the wear-resistant coating is set as a chrome plating coating. The chrome plating layer has a very high hardness, which can significantly improve the wear resistance of the base material, reduce friction and wear, and prevent the vibration generated during the processing of the watch case 17 from causing wear to the pallet 5.

[0036] During specific use, the watch case 17 is placed into the square hole 6 so that the bottom of the watch case 17 is flush with the top of the pallet 5. When the watch case 17 is horizontally pushed, the two arc-shaped holes 18 on the watch case 17 are respectively inserted into the corresponding clamping plates 8. During the movement of the watch case 17, the spring pin 19 is pressed into the internal slot. After the watch case 17 moves in place, the spring pin 19 pops up upward and is stuck into the through hole 20. The cooperation between the clamping plate 8 and the arc-shaped hole 18 limits the watch case 17 in the vertical direction, and the cooperation between the spring pin 19 and the through hole 20 limits the watch case 17 in the horizontal direction, realizing the stable clamping of the watch case 17.

[0037] Certainly, the present utility model can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by ordinary technicians in the art without any creative labor all fall within the scope protected by the present utility model.
