Technical Field
[0001] This utility model relates to the field of cutting technology, and in particular to a precision cutting device for watch straps. Background Technology
[0002] A watch is a small, portable instrument worn on the wrist to display time. Its main function is to visually show the current time through the movement of hands (such as hour, minute, and second hands) on the dial or a digital display. Different people have different wrist sizes, requiring watch straps of varying lengths. Traditional cutting devices often use simple manual pressing to secure watch straps, which cannot provide stable and precise fixation for straps of different sizes, shapes, and materials. The strap is prone to slipping or deforming during the cutting process, leading to inaccurate cutting dimensions. For metal straps, if not securely fixed, vibrations may occur during cutting, affecting cutting accuracy and the smoothness of the cut surface. Therefore, a precision watch strap cutting device is needed.
[0003] Chinese Patent Publication No. CN219902266U discloses a cutting device for watch strap processing, including a base. A control box is fixedly installed on one side surface of the base, a dust removal structure is fixedly installed on the upper surface of the base, an operating structure is fixedly installed on the upper surface of the dust removal structure, and an electric telescopic rod is fixedly installed on the lower surface of the operating structure near the front. A cutting structure is fixedly installed on the lower surface of the electric telescopic rod. The electric telescopic rod and the cutting structure are fixedly installed through a fixing structure, which includes a slide rail, a fixing plate, and a first screw hole. The fixing plate has two sets of slide rails inside. The watch strap cutting device described in the above patent document allows for more convenient disassembly and replacement of the cutting head, and can collect the debris generated during the cutting process, reducing the workload of manual labor.
[0004] However, the above-mentioned patent documents still have the following defects in practice;
[0005] Although the aforementioned patent document device can cut watch straps, it cannot firmly fix the watch strap during the cutting process, causing the watch strap to shift, wobble, or vibrate due to the cutting force. It cannot ensure the consistency of the cutting line with the preset path, and cannot make the cut watch strap edges smoother, thus reducing the cutting accuracy. Furthermore, it cannot allow the watch strap to move laterally, and cannot accurately control the distance and position of the lateral movement, nor can it accurately move the watch strap to the required cutting point. The cutting error caused by inaccurate positioning may reduce the cutting quality and product consistency. Utility Model Content
[0006] The main purpose of this invention is to provide a precision cutting device for watch straps, which can effectively solve the problem of not being able to fix them.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figure 1 As shown, a precision cutting device for watch straps includes a worktable 1, a cutting mechanism 4 fixedly connected to the upper rear part of the worktable 1, a translation mechanism 2 fixedly connected to the upper middle part of the worktable 1, clamping mechanisms 5 fixedly connected to the left and right sides of the translation mechanism 2, and a rotating mechanism 3 fixedly connected to the lower middle part of the worktable 1.
[0027] In the specific implementation process of this utility model, firstly, the watch strap is placed on the translation mechanism 2, and then the internal structure of the clamping mechanism 5 is rotated to fix the watch strap above the translation mechanism 2 by the left and right sides of the clamping mechanism 5. Then, the internal structure of the rotating mechanism 3 is rotated to drive the watch strap to move laterally on the translation mechanism 2, so that it is adjusted to a suitable distance to ensure the cutting accuracy of the watch strap. Finally, the internal drive structure of the cutting mechanism 4 is activated to cut the watch strap.
[0028] Specifically, in order to achieve the purpose of lateral movement of the watch strap, refer to Figure 3 In this scheme, the translation mechanism 2 includes a support plate 21, which is fixedly connected to the upper middle part of the workbench 1. The upper front and rear sides of the support plate 21 are provided with sliding grooves 22. The inner cavity of the two sliding grooves 22 is slidably connected to a placement plate 24. The upper front side of the support plate 21 is fixedly connected with a scale line 23. The middle part of the inner cavity of the support plate 21 is fixedly connected with a slide bar 25. The upper end of the slide bar 25 is slidably connected with a rack 26. The rack 26 is rotatably connected to the front part of the middle part of the inner cavity of the support plate 21 with a gear 27.
[0029] Furthermore, the outer surface of the rack 26 meshes with the outer surface of the gear 27.
[0030] In the above process, the watch strap is placed on the upper end of the placement plate 24, and then the gear 27 is rotated by rotating the internal structure of the rotating mechanism 3. The rotation of the gear 27 drives the rack 26 that meshes with it to slide in the inner cavity of the slide bar 25. In turn, the rack 26 drives the placement plate 24 to move laterally in the inner cavity of the slide groove 22. The distance of the watch strap movement can be observed at all times through the set scale line 23, so as to ensure the cutting accuracy of the watch strap.
[0031] Specifically, in order to secure the watch strap, refer to... Figure 5 In this scheme, the clamping mechanism 5 includes two support plates 51, which are fixedly connected to the middle of the left and right ends of the placement plate 24, respectively. Support blocks 53 are fixedly connected to the front and upper parts of the upper end of the support plate 51 near the placement plate 24. A rotating plate 54 is rotatably connected between the upper parts of the two opposing surfaces of the support blocks 53. A pressure block 55 is fixedly connected to the end of the rotating plate 54 near the placement plate 24. A circular groove 52 is opened on the upper end of the support plate 51 away from the placement plate 24. A screw 56 is threadedly connected to the upper end of the rotating plate 54 away from the placement plate 24. A ball 57 is fixedly connected to the lower end of the screw 56. The ball 57 is movably connected to the inner cavity of the circular groove 52.
[0032] In the above process, the watch strap is placed on the placement plate 24, and then the screw 56 is rotated. The rotation of the screw 56 causes the rotating plate 54 to rise away from the placement plate 24, so that the rotating plate 54 rotates at a certain angle on the surface of the support block 53. At the same time, through the provided circular groove 52, the screw 56 rotates while driving the ball 57 to rotate in the inner cavity of the circular groove 52. As one end of the rotating plate 54 rises, the ball 57 rotates at a certain angle in the inner cavity of the circular groove 52, thereby causing the pressure block 55 to press down on both ends of the watch strap, thus fixing the watch strap in place.
[0033] Specifically, for the purpose of driving gear 27 to rotate, refer to Figure 4 In this scheme, the rotating mechanism 3 includes a C-shaped plate 31 and a turntable 34. The C-shaped plate 31 is fixedly connected to the front side of the lower middle part of the workbench 1. The front and rear walls of the inner surface of the C-shaped plate 31 are rotatably connected to a rotating rod 32. The front and rear sides of the outer surface of the rotating rod 32 are fixedly connected to a gear set 33. The turntable 34 is rotatably connected to the front side of the upper middle part of the workbench 1.
[0034] Furthermore, both gear sets 33 are composed of two meshing bevel gears. The lower end of the turntable 34 passes through the upper end of the worktable 1 and is fixedly connected to the bevel gear in the front horizontal direction. The upper end of the bevel gear in the rear horizontal direction passes through the lower end of the worktable 1 through a rotating rod and is fixedly connected to the lower end of the gear 27.
[0035] In the above, the rotating disk 34 drives the rotating rod 32 to rotate through the bevel gear on the front side, and then drives the bevel gear on the rear side to rotate through the rotation of the rotating rod 32, which in turn drives the gear 27 to rotate through the rotating rod.
[0036] Specifically, in order to achieve the purpose of cutting the watch strap, refer to Figure 2 In this solution, the cutting mechanism 4 includes a fixed plate 41, which is fixedly connected to the upper rear side of the workbench 1. A horizontal plate 42 is fixedly connected to the upper front end of the fixed plate 41. A hydraulic cylinder 44 is fixedly connected to the upper end of the horizontal plate 42. The output end of the hydraulic cylinder 44 extends through the upper end of the horizontal plate 42 to the outside and is fixedly connected to a cutting blade 43.
[0037] In the above process, the hydraulic cylinder 44 is activated, and the cutting blade 43 is pressed down by the hydraulic cylinder 44, so that the cutting blade 43 cuts the watch strap.
[0038] It should be noted that the specific installation method, oil circuit connection method and control method of the hydraulic cylinder 44 used in this utility model are all conventional designs, and will not be described in detail in this utility model.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
