They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figure 1-11 As shown, this utility model discloses a watch needle cutting machine, including a frame 10, a cutting mechanism 20, a clamping and feeding mechanism 30 and a feeding and positioning component 40 disposed on the frame 10.

[0034] The cutting mechanism 20 has a first cutter 21, a second cutter 22 and a first driving device 23, wherein the first driving device 23 drives the first cutter 21 to move relative to the second cutter 22.

[0035] The clamping and feeding mechanism 30 has a clamping component 31 and a second driving device 32. The second driving device 32 drives the clamping component 31 to move closer to or away from the cutting mechanism 20. The second driving device 32 can be driven by a lead screw and a motor, or it can be driven by a cylinder.

[0036] The clamping assembly 31 has a mounting base 33, and a first clamping module 34 and a second clamping module 35 disposed on the mounting base 33. The first clamping module 34 and the second clamping module 35 are each provided with a positioning rod 344. When the first clamping module 34 and the second clamping module 35 clamp the dial indicator strap 50, the positioning rod 344 is inserted into the positioning hole 51 on the dial indicator strap 50.

[0037] The feeding and positioning component 40 can position the watch needle strip 50 to be cut, and the second driving device 32 can drive the clamping component 31 to move back and forth relative to the feeding and positioning component 40. By setting the feeding and positioning component 40, the watch needle strip 50 can be pre-positioned. Then, the clamping component 31 clamps the pre-positioned watch needle strip 50 and performs secondary positioning before transferring it to the cutting mechanism 20 for cutting. The positioning efficiency is high, which improves the production efficiency.

[0038] The feeding and positioning assembly 40 has a positioning base 41, and a first positioning block 42 and a second positioning block 43 disposed on the positioning base 41. The first positioning block 42 can position the short side of the dial indicator strap 50, and the second positioning block 43 can position the long side of the dial indicator strap 50. The first positioning block 42 and the second positioning block 43 are both connected to the positioning base 41 by screws. Multiple second positioning blocks 43 are provided at intervals along the left and right direction.

[0039] A positioning groove 44 is formed between the second positioning block 43 and the positioning seat 41. The positioning groove 44 has an opening that opens towards the cutting mechanism 20. The second positioning block 43 is provided with an elastic block 45 that extends into the positioning groove 44. The elastic block 45 can press the watch hand strap 50 downward onto the positioning seat 41. Specifically, during operation, the elastic block 45 presses the rear edge 53 of the watch hand strap 50 downward onto the positioning seat 41. The bottom of the elastic block 45 is provided with a guide slope 451, which extends from top to bottom away from the cutting mechanism 20. By setting the elastic block 45, the rear edge 53 of the watch hand strap 50 is pressed downward onto the positioning seat 41, preventing the watch hand strap 50 from shifting up and down, and facilitating the subsequent transfer of the watch hand strap 50 by the clamping assembly 31.

[0040] The elastic block 45 is movably connected to the second positioning block 43. The second positioning block 43 is provided with a third spring (not shown) and a limiting rod 46. The third spring makes the elastic block 45 always have a downward tendency. The limiting rod 46 passes through the elongated hole 452 on the elastic block 45. The elongated hole 452 extends in the vertical direction.

[0041] The positioning base 41 is provided with a plurality of left and right distributed clearance grooves 411, which allow the first clamping block 341 and the second clamping block 342 on the first clamping module 34 and the second clamping module 35 to move back and forth.

[0042] The first clamping module 34 has a first clamping block 341, a second clamping block 342, and a third driving device 343. The first clamping block 341 is located above the second clamping block 342. The third driving device 343 drives the first clamping block 341 to move up and down relative to the second clamping block 342. The positioning rod 344 is located on the first clamping block 341 and extends in the vertical direction. The second clamping block 342 is provided with a clearance hole 345 for the positioning rod 344 to extend into. The third driving device 343 can be a cylinder.

[0043] The first clamping module 34 and the second clamping module 35 are distributed in the left-right direction. The mounting base 33 is provided with an adjustment component 36. The first clamping module 34 can be adjusted left and right on the mounting base 33 through the adjustment component 36. By setting the adjustment component 36, the distance between the positioning rods 344 on the first clamping module 34 and the second clamping module 35 in the left-right direction can be adjusted to adapt to the positioning holes 51 on different dial indicator straps 50, which has good versatility and high positioning accuracy.

[0044] The adjustment assembly 36 has an adjustment seat 361, a movable part 362, and a first spring 363. The adjustment seat 361 is fixedly connected to the mounting seat 33. The first clamping module 34 is slidably mounted on the adjustment seat 361 via the first guide rod 364. The movable part 362 is disposed on the adjustment seat 361. The movable part 362 can push the first clamping module 34 closer to the second clamping module 35. The first spring 363 ensures that the first clamping module 34 always moves away from the second clamping module 35. Specifically, the movable part 362 is a micrometer, or it can be a screw. The first spring 363 can be a compression spring or a tension spring.

[0045] The mounting base 33 is also provided with a third clamping module 37. The first clamping module 34, the second clamping module 35, and the third clamping module 37 are arranged in a straight line along the left and right direction. The third clamping module 37 can be adjusted left and right to be installed on the mounting base 33. The structures of the second clamping module 35 and the third clamping module 37 are similar to those of the first clamping module 34, so they will not be described in detail. By setting the third clamping module 37, it is suitable for longer dial indicator straps 50.

[0046] The driving end of the second driving device 32 is connected to a base 321. The base 321 is slidably connected to the frame 10. The mounting seat 33 is slidably connected to the base 321. The base 321 is provided with a fourth driving device 322 that drives the mounting seat 33 to move up and down. The fourth driving device 322 can be a cylinder. By setting the fourth driving device 322 to drive the mounting seat 33 to move up and down, the up and down position of the dial indicator strap 50 can be adjusted, so that the cutting mechanism 20 can achieve better cutting effect. When the dial indicator strap 50 is cut multiple times, the connecting shaft 55 on the dial indicator strap 50 can be prevented from colliding with the second cutter 22 or other structures on the equipment, thereby facilitating the transfer and height adjustment of the dial indicator strap 50.

[0047] A second spring 323 is provided between the base 321 and the mounting base 33. The second spring 323 makes the mounting base 33 always tend to move downward. By setting the second spring 323, the mounting base 33 has a buffering effect when moving up and down.

[0048] The base 321 is provided with a connecting plate 324, and the mounting seat 33 is located between the connecting plate 324 and the base 321. The second spring 323 is a compression spring. The upper end of the compression spring abuts against the connecting plate 324, and the lower end of the compression spring abuts against the mounting seat 33. The mounting seat 33 is slidably connected to the connecting plate 324 through the second guide rod 325. The second spring 323 can also be a tension spring.

[0049] The first cutter 21 is positioned above the second cutter 22. The first driving device 23 drives the first cutter 21 to move up and down. The blade of the first cutter 21 extends upward or downward from left to right at an angle. The blade of the second cutter 22 extends horizontally from left to right. The first driving device 23 can be a cylinder. By setting the blade of the first cutter 21 to extend upward or downward from left to right at an angle, for example, by setting the blade of the first cutter 21 to extend upward from left to right at an angle, the first cutter 21 will cut the watch hand strap 50 from the left side to the right side during cutting, resulting in a better cutting effect and preventing deformation of the watch hand 54. It should be noted that scissors can also be used instead of the first cutter 21 and the second cutter 22.

[0050] A collection box 60 is provided below the first cutter 21. The collection box 60 can collect the cut watch hands 54 and can be moved.

[0051] The working principle of this utility model:

[0052] The worker pushes the watch hand strap 50 to be cut from front to back into the positioning groove 44 through the opening, so that the short side of the watch hand strap 50 abuts against the first positioning block 42 and the long side of the watch hand strap 50 abuts against the second positioning block 43. The elastic block 45 presses the edge of the watch hand strap 50 downward onto the positioning seat 41.

[0053] The third driving device 343 drives the first clamping block 341 to move down, and the first clamping block 341 drives the positioning rod 344 to move down, so that the positioning rod 344 is inserted into the positioning hole 51 of the rear edge 53 of the dial needle strap 50. At the same time, the first clamping block 341 and the second clamping block 342 respectively clamp the upper and lower surfaces of the rear edge 53 of the dial needle strap 50.

[0054] The second driving device 32 drives the clamping assembly 31 to move toward the cutting mechanism 20. The front edge 52 of the watch hand strap 50 extends forward past the first cutter 21 and the second cutter 22. The first driving device 23 drives the first cutter 21 to move downward. The first cutter 21 cuts the watch hand strap 50 from the left side to the right side, removing the front edge 52 of the watch hand strap 50.

[0055] The fourth driving device 322 drives the clamping assembly 31 to move upward, and the clamping assembly 31 drives the watch hand strap 50 to move upward to a certain height. The second driving device 32 drives the clamping assembly 31 to move towards the cutting mechanism 20. The first driving device 23 drives the first cutter 21 to move downward. The first cutter 21 cuts the watch hand strap 50 from the left side to the right side, cutting off the rear edge 53 of the watch hand strap 50, so that the front end of the watch hand 54 is separated from the front edge 52 and the rear end of the watch hand 54 is separated from the rear edge 53. After cutting, the watch hand 54 and the front edge 52 fall into the collection box 60.

[0056] The second drive device 32 drives the clamping assembly 31 to move away from the cutting mechanism 20. The clamping assembly 31 drives the remaining rear edge 53 to move, and the worker removes the rear edge 53 to complete the cutting operation of the watch needle strap 50.

[0057] In summary, this utility model provides a cutting mechanism 20 and a clamping and feeding mechanism 30 on a frame 10. The cutting mechanism 20 has a first cutter 21, a second cutter 22, and a first driving device 23. The clamping and feeding mechanism 30 has a clamping assembly 31 and a second driving device 32. The clamping assembly 31 has a mounting base 33, and a first clamping module 34 and a second clamping module 35 mounted on the mounting base 33. Both the first clamping module 34 and the second clamping module 35 are provided with positioning rods 344. During operation, while the first clamping module 34 and the second clamping module 35 clamp the dial indicator strap 50, the positioning rods 344 are inserted into the positioning holes 51 on the dial indicator strap 50. The positioning rods 344 and the positioning holes 51 on the dial indicator strap 50 are used to position the dial indicator strap 50. When cutting the dial indicator 54, the position of the dial indicator strap 50 is prevented from shifting, improving the cutting accuracy of the dial indicator 54 and achieving better results.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
