Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing technology, specifically to a watch strap hole-opening device for watch manufacturing. Background Technology

[0002] When manufacturing watches, holes need to be drilled in the watch straps. Typical watch strap drilling devices can only drill one hole per strap at a time, resulting in significant processing time when processing large batches of straps. This severely reduces the drilling speed. Furthermore, because different types of watch straps have different specifications, it's difficult for a single drilling device to adjust the drilling spacing. Therefore, multiple sets of watch strap drilling devices with different drilling gaps are needed for different types of straps, which reduces practicality.

[0003] According to a watch strap punching device for convenient adjustment of hole spacing (Announcement No.: CN112111615A), the above application sets multiple push rods at the lower part of the support plate. When the drive rack rotates one revolution, it can cooperate with the upper and lower bevel gears to make the transmission screw rotate back and forth, unscrewing and screwing the threaded sleeve. This allows the push rod to be driven to be pressed into the watch strap and quickly disengaged from the watch strap, making multiple holes in the watch strap at a time, thereby improving the punching speed of the watch strap.

[0004] However, only a single-diameter hole can be drilled in the watch strap. Different types of watch straps require different hole diameters due to differences in function, design, or wearing needs. For example, some watch straps require a larger hole diameter to accommodate a thicker clasp pin, while delicate decorative watch straps may only require a small hole diameter for connection. A single-diameter drilling device cannot cover these diverse needs, resulting in its applicability only to specific watch strap sizes and a narrow range of applications. Utility Model Content

[0005] The purpose of this utility model is to provide a watch strap hole-opening device for watch processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a watch strap opening device for watch processing, comprising a base plate, four sets of columns fixedly connected to the surface of the base plate, a top plate fixedly connected to the top of the columns, an opening assembly provided on the bottom surface of the top plate, the opening assembly comprising a hydraulic rod, the hydraulic rod fixedly connected to the surface of the top plate, the output shaft of the hydraulic rod passing through and slidably connected to the surface of the top plate, a bearing plate fixedly connected to the bottom end of the output shaft of the hydraulic rod, a plurality of arrayed transmission wheels rotatably connected to the bottom surface of the bearing plate, a rotating rod fixedly connected to the bottom of the transmission wheels, the diameter of the rotating rod gradually decreasing from top to bottom.

[0007] Preferably, a fixing component is provided on the surface of the base plate. The fixing component includes a support plate, which is fixedly connected to the surface of the base plate. A placement plate is fixedly connected to the surface of the support plate. Sliding grooves are provided on both sides of the placement plate. Two sets of symmetrically arranged mounting brackets are slidably connected inside the sliding grooves. A through hole is provided on the surface of the mounting bracket, and a lead screw is threaded into the through hole. A rotating wheel is fixedly connected to one end of the lead screw, and a pressure plate is rotatably connected to the bottom end of the lead screw.

[0008] Preferably, a guide rod is fixedly connected to the surface of the bearing plate, and the guide rod passes through and is slidably connected to the surface of the top plate.

[0009] Preferably, a motor is fixedly connected to the surface of the support plate, the output shaft of the motor passes through and is rotatably connected to the bottom surface of the support plate, and the output shaft of the motor is fixedly connected to the surface of the transmission wheel.

[0010] Preferably, the multiple sets of drive wheels are connected by a synchronous belt drive.

[0011] Preferably, the side wall of the mounting bracket is provided with a guide groove, and a guide block is slidably connected inside the guide groove.

[0012] Preferably, the surface of the placement plate has a through groove.

[0013] Compared with the prior art, this utility model provides a watch strap hole-opening device for watch processing, which has the following beneficial effects:

[0014] 1. This watch strap drilling device for watch processing uses multiple sets of synchronously rotating rods and a vertically moving structure driven by hydraulic rods. The diameter of the rotating rods gradually decreases from top to bottom. Without replacing any parts, the drilling diameter can be flexibly controlled simply by adjusting the depth of the rotating rods inserted into the watch strap. This solves the problem of adapting to different hole diameter requirements and enhances the versatility of the device.

[0015] 2. The watch strap drilling device for watch processing, through the sliding cooperation of the slide groove and the mounting bracket, can flexibly adjust the spacing of the two sets of mounting brackets according to the width of the watch strap. Combined with the screw-driven pressure plate and the perpendicularity protection structure of the guide block and the guide groove, it can stably press watch straps of different specifications, avoid displacement or tilting during drilling, and ensure the accuracy of the drilling position.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a watch strap hole-opening device for watch processing, including a base plate 1, four sets of columns 11 are fixedly connected to the surface of the base plate 1, and a top plate 12 is fixedly connected to the top of the columns 11. The device is supported by the base plate 1 as a foundation, and the four sets of columns 11 and the top plate 12 form a stable frame structure.

[0021] A hole-opening assembly 2 is provided on the bottom surface of the top plate 12. The hole-opening assembly 2 includes a hydraulic rod 21, which is fixedly connected to the surface of the top plate 12. The output shaft of the hydraulic rod 21 passes through and is slidably connected to the surface of the top plate 12. A support plate 22 is fixedly connected to the bottom end of the output shaft of the hydraulic rod 21. The hydraulic rod 21 drives the support plate 22 to move up and down through the extension and retraction of the output end, providing vertical pressure for drilling. A guide rod 23 is fixedly connected to the surface of the support plate 22, which passes through and is slidably connected to the surface of the top plate 12. The guide rod 23 ensures the stability of the support plate 22 when it moves up and down, and avoids deviation during drilling.

[0022] The bottom surface of the support plate 22 is rotatably connected to multiple sets of arrayed transmission wheels 24. The multiple sets of transmission wheels 24 are connected by synchronous belts 25. The bottom of the transmission wheels 24 is fixedly connected to a rotating rod 26. The diameter of the rotating rod 26 gradually decreases from top to bottom. By adjusting the depth of the rotating rod 26 inserted into the watch strap, the different diameter segments of the rotating rod 26 that gradually decrease from top to bottom are used. The deeper the insertion, the larger the hole diameter, and different sizes of holes can be made. The hole diameter can be adjusted without replacing the rotating rod 26.

[0023] A motor 27 is fixedly connected to the surface of the support plate 22. The output shaft of the motor 27 passes through and is rotatably connected to the bottom surface of the support plate 22. The output shaft of the motor 27 is fixedly connected to the surface of the transmission wheel 24. The output shaft of the motor 27 is connected to a set of transmission wheels 24. Multiple sets of transmission wheels 24 are connected by a synchronous belt 25 to realize the synchronous rotation of multiple sets of rotating rods 26, providing rotational cutting power for drilling.

[0024] A fixing component 3 is provided on the surface of the base plate 1. The fixing component 3 includes a support plate 31, which is fixedly connected to the surface of the base plate 1. A placement plate 32 is fixedly connected to the surface of the support plate 31. A through groove 33 is provided on the surface of the placement plate 32. The surface of the placement plate 32 is used to place the watch strap to be processed. The through groove 33 provides clearance space for drilling the rotating rod 26, so as to avoid collision between the rotating rod 26 and the placement plate 32.

[0025] Both sides of the mounting plate 32 are provided with sliding grooves 34. Two sets of symmetrically arranged mounting brackets 35 are slidably connected inside the sliding grooves 34. The sliding grooves 34 provide adjustment space for the two sets of mounting brackets 35, and the spacing can be adjusted according to the width of the watch strap to accommodate different sizes of watch straps. The surface of the mounting bracket 35 is provided with through holes, and a lead screw 36 is threaded into the through holes. One end of the lead screw 36 is fixedly connected to a rotating wheel 37, and the bottom end of the lead screw 36 is rotatably connected to a pressure plate 38. By rotating the rotating wheel 37, the lead screw 36 can drive the pressure plate 38 to move downward, pressing the watch strap tightly onto the mounting plate 32 to prevent the watch strap from shifting during drilling.

[0026] The side wall of the mounting bracket 35 is provided with a guide groove 39, and a guide block 310 is slidably connected inside the guide groove 39. The guide block 310 cooperates with the guide groove 39 to ensure the verticality of the pressure plate 38 when it moves, and avoids unstable clamping caused by tilting.

[0027] In this utility model, when in use, first slide two sets of mounting brackets 35 along the sliding grooves 34 on both sides of the placement plate 32 according to the width of the watch strap to be processed. After adjusting to the spacing that matches the width of the watch strap, place the watch strap flat on the surface of the placement plate 32, ensuring that the position to be drilled corresponds to the rotating rod 26 of the hole opening component 2 and is located directly above the through groove 33.

[0028] Subsequently, rotating the wheel 37 on the mounting bracket 35 causes the lead screw 36 to rotate. Under the action of the thread, the lead screw 36 pushes the pressure plate 38 downward until the pressure plate 38 is tightly pressed against the surface of the watch strap. During this process, the guide block 310 on the side wall of the pressure plate 38 slides synchronously along the guide groove 39 to ensure that the pressure plate 38 moves vertically downward and avoids unstable fixing of the watch strap due to tilting.

[0029] After the watch strap is secured, the motor 27 is started. The output shaft of the motor 27 drives the connected transmission wheel 24 to rotate. Through the transmission action of the synchronous belt 25, multiple sets of transmission wheels 24 rotate synchronously, thereby driving the bottom rotating rod 26 to rotate as well. At this time, the control hydraulic rod 21 extends, and its output shaft pushes the support plate 22 to move downward. The guide rod 23 slides synchronously along the top plate 12 to ensure that the support plate 22 moves downward smoothly.

[0030] As the rotating rod 26 moves downward with the support plate 22, its tapered structure, with its diameter gradually decreasing from top to bottom, allows for a larger hole diameter as it is inserted deeper into the watchband. Once the rotating rod 26 rotates through the watchband and into the through slot 33, completing the drilling of the specified diameter, the hydraulic rod 21 retracts, causing the support plate 22 and the rotating rod 26 to return to their original position and detach from the watchband.

[0031] Finally, rotate wheel 37 in the opposite direction to move screw 36 upwards, causing pressure plate 38 to move upwards and release the pressure on the watch strap. The finished watch strap can then be removed from the placement plate 32, completing one drilling operation. To process watch straps of different specifications, repeat the above steps to adjust the spacing of mounting brackets 35 and the insertion depth of rotating rod 26.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
