Description

Technical Field

[0001] The present invention belongs to the technical field of stainless steel watchband parts processing, and more specifically, relates to a stainless steel watchband parts processing and positioning device. Background Art

[0002] In the processing of stainless steel watchband parts, especially in precision machining processes like drilling, the positioning accuracy of the strap beads is a key factor in determining product quality. Any deviation in positioning can easily lead to part scrapping or performance degradation, directly impacting production efficiency.

[0003] Currently, existing watchband component processing and positioning devices have exposed many shortcomings in practical applications: First, the positioning structure design is relatively simple, and most use manual clamping or a single slot positioning method. This method makes it difficult to ensure uniform clamping force, which can easily cause the watchband particles to shift during processing, resulting in processing errors and reduced product precision. Second, the mold replacement process is cumbersome and inconvenient. When processing watchband particles of different specifications, it is often necessary to disassemble multiple fixed components, which requires multiple steps and is time-consuming. This not only increases the labor intensity of workers, but also seriously restricts the improvement of production efficiency. In view of this, the existing structure and shortcomings are studied and improved, and a stainless steel watchband component processing and positioning device is provided to achieve a more practical and valuable purpose.

[0024] Example:

[0025] As attached Figure 1 To the attached Figure 5 As shown:

[0026] The present invention provides a stainless steel watchband parts processing and positioning device, comprising a workbench 1 placed on one side of a drilling machine, a molding frame 2 fixedly installed on the top of the workbench 1, a linear motor module 3 installed on the bottom end of the horizontal section of the molding frame 2, and a movable frame 4 slidably connected to the bottom end of the linear motor module 3, a fixed plate 1 slidably connected to the inner top of the movable frame 4, a fixed plate 2 slidably connected to the inner bottom of the movable frame 4, mounting grooves are provided on opposite sides of the fixed plate 1 5 and the fixed plate 2 6, an upper mold 7 is installed in the mounting groove of the fixed plate 1 5, a lower mold 8 is installed in the mounting groove of the fixed plate 2 6, and a plurality of through grooves matching the shape of the watchband particles are provided in the horizontal direction on the plane at the connection between the upper mold 7 and the lower mold 8.

[0027] Among them, multiple groups of electric push cylinders 9 are vertically installed on the inner top surface and the inner bottom surface of the movable frame 4, and the output ends of the multiple groups of electric push cylinders 9 on the same surface are respectively fixedly connected to the corresponding fixed plate 1 5 and fixed plate 2 6. The electric push cylinders 9 provide a stable and controllable driving force for the movement of the fixed plate 1 5 and the fixed plate 2 6. At the same time, it also enhances the adaptability of the device to the processing requirements of upper molds 7 and lower molds 8 of different thicknesses.

[0028] Among them, guide grooves are provided on both inner side walls of the movable frame 4, and the guide grooves are T-shaped. Guide blocks 10 that slide and match the two sets of guide grooves are installed on both sides of the fixed plate 1 5 and the fixed plate 2 6, providing precise guidance for the vertical movement of the fixed plate 1 5 and the fixed plate 2 6. At the same time, the T-shaped structure has good anti-slip performance, ensuring that the upper mold 7 and the lower mold 8 always maintain precise alignment during the clamping process.

[0029] Among them, electromagnets 12 are installed inside the two groups of mounting grooves, and the materials of the upper mold 7 and the lower mold 8 are both metal materials that can be adsorbed by the electromagnet 12, which realizes the rapid fixation and replacement of the upper mold 7 and the lower mold 8, greatly shortens the mold change time, improves the production switching efficiency, and ensures that the mold has no displacement during the processing process.

[0030] Among them, mounting plates 13 are connected to both sides of the bottom end of the workbench 1, and mounting holes are opened inside the mounting plates 13 to provide a stable fixing method for the device, avoid device displacement caused by vibration during processing, and ensure that positioning accuracy is not affected.

[0031] Among them, guide plates 14 are obliquely provided on the top of the second fixing plate 6 and on both sides of the installation groove, which can guide and discharge metal debris generated during drilling, thereby improving the convenience of using the device.

[0032] Among them, a waist-shaped groove 15 is provided at the top of the workbench 1, and a limiting column 11 is vertically installed at the bottom end of the movable frame 4, which is slidably connected to the waist-shaped groove 15, and can provide limiting and guiding functions for the lateral sliding of the movable frame 4. This design enhances the movement stability and operation reliability of the movable frame 4, and avoids offset or jamming during the sliding process.

[0033] The working principle of this embodiment is as follows:

[0034] When the device is in use, the electric push cylinders 9 on the top and bottom surfaces of the moving frame 4 are first started synchronously. With the cooperation of the guide blocks 10 on both sides of the fixed plate 1 5 and the fixed plate 2 6 and the guide grooves on the inner wall of the moving frame 4, the electric push cylinders 9 drive the fixed plate 1 5 and the fixed plate 2 6 to move away from each other in the vertical direction. Then the upper mold 7 and the lower mold 8 are respectively installed on the fixed plate 1 5 and the fixed plate 2 6 through the mounting grooves. After the electromagnet 12 in the mounting groove is energized, it can adsorb the upper mold 7 and the lower mold 8 made of metal material to achieve rapid fixation of the mold. When it is necessary to replace molds of different specifications, it is only necessary to disconnect the power supply of the electromagnet 12 to easily remove the old mold and install the new mold, which greatly shortens the mold change time.

[0035] Then, the watch strap particles to be processed are placed in the through grooves formed by the upper mold 7 and the lower mold 8 in turn, and the electric push cylinder 9 is started again, so that the electric push cylinder 9 drives the fixed plate 1 5 and the fixed plate 2 6 to approach each other in the vertical direction until the two are fitted together, thereby tightly clamping the watch strap particles to ensure that there is no displacement during the processing process.

[0036] Then you can start the drilling machine to drill the strap particles. During the drilling process, the linear motor module 3 at the bottom of the horizontal section of the profile frame 2 can drive the movable frame 4 to slide horizontally with the cooperation of the limit column 11 at the bottom of the movable frame 4 and the waist-shaped groove 15 at the top of the workbench 1, so as to realize drilling in sequence. At the same time, the guide plates 14 on both sides of the fixed plate 2 6 can guide and discharge the metal debris generated during drilling.

[0037] It should be noted that the linear motor module 3 is a device or equipment existing in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art and are common knowledge in the art, so they will not be described in detail.

[0038] The embodiments of the present invention are presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
