Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing technology, and in particular to an interchangeable punching hardware fixture for watch strap production. Background Technology

[0002] Watches are common everyday items, typically consisting of a watch face and a watch strap. Modern watch straps, besides their wearing function, also serve a decorative purpose, and are usually made of plastic. In the watch strap production process, punching is a crucial step in manufacturing metal watch straps, used to create connecting holes. Existing punching fixtures usually have multiple fixing screws erected on the upper surface of the mounting base. These screws correspond to the four corners of fixture components (such as positioning seats) to secure the positioning seat. Replacing the positioning seat requires removing these four corner fixing screws (multiple screws need to be removed), which is cumbersome. Furthermore, the fixing screws protrude from the upper surface of the positioning seat, interfering with worker operations. Therefore, it is necessary to propose a new solution to address these problems. Utility Model Content

[0003] In view of this, the present invention addresses the deficiencies of the prior art by providing an interchangeable punching head fixture for watch strap production, which solves the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An interchangeable punching head fixture for watch strap production includes a base, a mounting base, a positioning base for positioning the watch strap to be punched, a punching head module for punching holes in the watch strap, and a driving mechanism for driving the punching head module to move up and down. The mounting base is disposed on the base, and the upper surface of the rear end of the mounting base is recessed with a front-to-back extending limiting groove. The rear end of the limiting groove is connected to a retaining groove that restricts left-to-right and up-to-down movement. The front end of the mounting base is provided with a front-to-back extending limiting rod and a fixing screw hole extending in the front-to-back direction.

[0006] The bottom of the rear end of the positioning seat is provided with a limiting protrusion, and the bottom of the front end of the positioning seat is provided with a limiting hole and a through hole.

[0007] During installation, the limiting protrusion slides backward in the aforementioned limiting groove and gets stuck in the groove. During the backward sliding process, the limiting hole fits into the aforementioned limiting rod. The through hole corresponds to the aforementioned fixing screw hole. The shaft of a fastening screw passes through the through hole and is screwed into the fixing screw hole, thereby fixing the rear end of the positioning seat to the rear end of the mounting seat with the screw.

[0008] As a preferred embodiment, the base is provided with two support plates arranged on the left and right, forming a waste material drop space between the two support plates. The mounting seat is located on the top of the two support plates and has a waste material through hole. The positioning seat has a die through hole, and the positions of the waste material drop space, the waste material through hole, and the die through hole correspond to each other.

[0009] As a preferred embodiment, the mounting base is provided with a limiting plate that is fixed by screws. The limiting plate partially covers the rear end of the limiting slide groove, thereby forming the aforementioned slot with the rear end of the limiting slide groove.

[0010] As a preferred embodiment, the bottom rear end of the positioning seat is fixed with a first connecting member by screws, and the first connecting member has the aforementioned limiting protrusion.

[0011] As a preferred embodiment, the front end of the positioning seat is fixed with a second connector by screws, and the second connector has the aforementioned limiting hole and through hole.

[0012] As a preferred embodiment, the front end of the mounting base has a connecting screw hole, one end of the limiting rod is a threaded rod and the other end is a cylinder, the threaded rod is screwed into the connecting screw hole, and the aforementioned limiting hole is sleeved on the cylinder.

[0013] As a preferred embodiment, the cylinder is provided with an elastic washer, which is tightly clamped between the front end face of the second connector and the mounting base in the installed state.

[0014] As a preferred embodiment, there are two limiting holes, and one through hole and one fixing screw hole, with the two limiting holes located on both sides of the through hole.

[0015] As a preferred embodiment, the projected profile of the screw head of the fastening screw is non-circular and corresponds to the through hole, so that the screw head of the fastening screw can pass through the through hole and be locked on the outside of the through hole after being rotated to the corresponding position.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0017] The positioning seat can be quickly installed and interchanged using a sliding snap-fit ​​structure and a single fastening screw. During installation and disassembly, only one fastening screw needs to be tightened, and then the positioning seat is slid out or into the slot. Specifically, during installation, the limiting protrusion slides backward in the aforementioned limiting groove and engages within it. During this backward sliding, the limiting hole aligns with the aforementioned limiting rod, and the through hole corresponds to the aforementioned fixing screw hole. The shaft of a fastening screw passes through the through hole and is screwed into the fixing screw hole, thus fixing the rear end of the positioning seat to the rear end of the mounting seat. This significantly shortens the fixture replacement time. Furthermore, the fastening screw is located at the bottom of the front end of the positioning seat, which does not interfere with the employee's normal punching operations, improving the operating experience.

[0018] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0029] Please see Figures 1 to 6 This utility model provides an interchangeable punching head fixture for watch strap production, including a base 10, a mounting base 20, a positioning base 30 for positioning the watch strap to be punched, a punching head module 40 for punching holes in the watch strap, and a driving mechanism 50 for driving the punching head module 40 to move up and down. The mounting base 20 is disposed on the base 10. The upper surface of the rear end of the mounting base 20 is recessed with a front-to-back extending limiting groove 21. The rear end of the limiting groove 21 is connected to a retaining groove 22 that can restrict left-to-right and up-to-down movement. The front end of the mounting base 20 is provided with a front-to-back extending limiting rod 23 and a fixing screw hole 24 extending in the front-to-back direction.

[0030] The bottom of the rear end of the positioning seat 30 is provided with a limiting protrusion 31, and the bottom of the front end of the positioning seat 30 is provided with a limiting hole 32 and a through hole 33.

[0031] During installation, the limiting protrusion 31 slides backward in the aforementioned limiting groove 21 and gets stuck in the slot 22. During the backward sliding process, the limiting hole 32 fits into the aforementioned limiting rod 23. The through hole 33 corresponds to the aforementioned fixing screw hole 24. The shaft of a fastening screw 60 passes through the through hole 33 and is screwed into the fixing screw hole 24, thereby fixing the rear end of the positioning seat 30 to the rear end of the mounting seat 20 with screws.

[0032] The positioning seat 30 can be quickly installed and interchanged using a sliding snap-fit ​​structure and a single fastening screw 60. During installation and disassembly, only one fastening screw 60 needs to be tightened, and then the positioning seat 30 can be slid out / slid into the slot 22 to achieve disassembly and assembly, which greatly shortens the fixture replacement time. Moreover, the fastening screw 60 is located at the bottom of the front end of the positioning seat 30, which will not affect the employee's normal punching operation and improve the operating experience.

[0033] Furthermore, the base 10 is provided with two support plates 70 arranged on the left and right, forming a waste material drop space 71 between the two support plates 70. The mounting seat 20 is set on the top of the two support plates 70. The mounting seat 20 has a waste material through hole 3325. The positioning seat 30 has a die through hole 3433. The positions of the waste material drop space 71, the waste material through hole 3325 and the die through hole 3433 are corresponding. In this way, the debris generated by punching can fall automatically and be collected.

[0034] Furthermore, the mounting base 20 is provided with a limiting plate 26 fixed by screws. The limiting plate 26 partially covers the rear end of the limiting slide groove 21, thereby forming the aforementioned slot 22 with the rear end of the limiting slide groove 21. This facilitates quick replacement or repair of the slot 22 components (e.g., when worn), extends the service life of the fixture, and is easy to process.

[0035] Furthermore, the bottom rear end of the positioning seat 30 is fixed with a first connector 35 by screws, and the first connector 35 has the aforementioned limiting protrusion 31; the limiting protrusion 31 can be replaced by simply replacing the screws, which reduces the cost of component wear and improves maintainability.

[0036] Furthermore, the front end of the positioning seat 30 is fixed with a second connector 36 by screws. The second connector 36 has the aforementioned limiting hole 32 and through hole 33. This allows the limiting hole 32 and through hole 33 to be replaced by simply replacing the screws, reducing component wear costs. At the same time, it improves maintainability and facilitates processing.

[0037] Furthermore, the front end of the mounting base 20 has a connecting screw hole (not shown in the figure), one end of the limiting rod 23 is a threaded rod (not shown in the figure), and the other end is a cylinder 231. The threaded rod is screwed into the connecting screw hole, and the aforementioned limiting hole 32 is sleeved on the cylinder 231. This structure is simple and easy to process.

[0038] Furthermore, the cylinder 231 is provided with an elastic washer 27. In the installed state, the elastic washer 27 is tightly clamped between the front end face of the second connector 36 and the mounting base 20. The elastic washer 27 provides pre-tightening force to ensure that the connector fits tightly, thereby enhancing the reliability and safety during the punching process.

[0039] Furthermore, there are two limiting holes 32, and one through hole 33 and one fixing screw hole 24. The two limiting holes 32 are located on both sides of the through hole 33. The two limiting holes 32 distributed on both sides of the through hole 33 provide dual-point constraint, effectively preventing the positioning seat 30 from rotating or tilting during installation and use.

[0040] Furthermore, the projected outline of the screw head of the fastening screw 60 is non-circular and corresponds to the through hole 33, so that the screw head of the fastening screw 60 can pass through the through hole 33 and be locked on the outside of the through hole 33 after being rotated to the corresponding position. The non-circular screw head can be locked by simple rotation (such as rotating 90° to fix it), preventing the screw from loosening under vibration. At the same time, it simplifies the installation steps, can be completed quickly without auxiliary tools (such as wrenches), optimizes the user experience, and is suitable for production environments where fixtures are frequently changed.

[0041] Additionally, it should be noted that the aforementioned drive mechanism 50 is a conventional structure in the prior art, and there are many similar structures, so it will not be described in detail here.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
