Description

Technical Field

[0001] This utility model relates to the field of CNC fixture technology, and in particular to a CNC high-gloss machining fixture for watch strap edge beads. Background Technology

[0002] CNC high-gloss machining fixtures are devices specifically designed for fixing and positioning workpieces during high-gloss surface machining on CNC (Computer Numerical Control) machine tools. Their core function is to ensure workpiece stability during high-speed, high-precision machining, thereby achieving a mirror-like high-gloss surface effect. Currently, CNC high-gloss machining fixtures are characterized by the following features: high rigidity design: Since high-gloss machining typically involves high-speed cutting, the fixture must possess extremely high rigidity to prevent surface defects (such as chatter marks) caused by vibration during machining; precise positioning and clamping: Using vacuum chucks, precision vises, or customized fixtures ensures zero workpiece displacement, with positioning accuracy typically required to reach the micrometer (μm) level to match the fine requirements of high-gloss machining; material compatibility: For common high-gloss materials (such as aluminum alloys, stainless steel, and acrylic), the fixture contact surfaces may use non-metallic gaskets or soft alloys to prevent damage to the workpiece surface; heat dissipation and corrosion resistance: High temperatures may be generated during machining, requiring the fixture to have good heat dissipation; if coolant is used, the fixture material must be rust-resistant. Customized structures are used for workpieces with complex shapes (such as mobile phone frames and watch straps). The fixtures may be designed with contour-following structures or combined clamping to ensure uniform force distribution.

[0003] In particular, existing fixtures have several problems in the CNC high-gloss machining of watch strap beads. Firstly, insufficient positioning accuracy makes it difficult to ensure the beads are in the correct position during machining, resulting in surface finish and smoothness that fail to meet high-quality requirements, affecting product appearance and quality. Secondly, the clamping process is cumbersome, time-consuming, reduces production efficiency, and increases production costs. Furthermore, existing fixtures lack versatility, making them unsuitable for machining watch strap beads of different specifications and styles, thus limiting their application range.

[0031] Please see Figs. 1-2This utility model discloses a CNC high-gloss machining fixture 1 for watch strap bead edge processing. The CNC high-gloss machining fixture 1 for watch strap bead edge processing includes a base 10, a clamping mechanism 20, and a cover 30. The clamping mechanism 20 is installed on the top side surface of the base 10, and the cover 30 is fastened to the top side surface of the clamping mechanism 20, thereby forming the overall fixture structure. The clamping mechanism 20 includes a tray 21, several fixed plates 22, several positioning plates 23, and a clamping assembly. The bottom surface of the tray 21 is connected to the top surface of the base 10, and the top surface of the tray 21 is connected to the bottom surface of the cover 30. Several fixed plates 22 are equidistantly arranged on both sides of the top surface of the tray 21 along the length direction of the tray 21. Several positioning plates 23 are respectively matched with several fixed plates 22, and each positioning plate 23 is movably fitted into the tray 21. The clamping assembly is arranged between the two fixed plates 22 along the length direction of the tray 21, and the clamping assembly is movably connected to the tray 21. The movable end of the clamping assembly is matched with the fixed plates 22 and positioning plates 23 on both sides. Based on this, the watch strap workpiece to be high-gloss processed is movably fitted between the corresponding fixing plate 22 and the positioning plate 23. Thus, the positioning plate 23, in conjunction with the fixing plate 22, accommodates and positions the watch strap workpiece. The movable end of the clamping mechanism 20 abuts against the side surface of the watch strap workpiece, thereby achieving stable clamping of the watch strap workpiece by the clamping mechanism 20. Furthermore, the clamping assembly includes a drive unit 24 and two clamping units 25. The drive unit 24 is movably mounted on the support plate 21, and the two clamping units 25 are respectively disposed on both sides of the drive unit 24. Thus, the drive unit 24 can drive the two clamping units 25 to move towards the corresponding fixing plate 22, thereby coordinating with the corresponding fixing plate 22 and positioning plate 23 to stably clamp the watch strap workpiece. Compared to existing CNC machining fixtures, the watch strap bead CNC high-gloss machining fixture 1 of this utility model, through the coordinated cooperation between the fixing plate 22, the positioning plate 23 and the clamping unit 25, can accurately position the watch strap workpiece while improving the clamping stability of the fixture on the watch strap workpiece with a simple clamping structure, thereby greatly improving the high-gloss machining accuracy and yield of the watch strap workpiece.

[0032] Furthermore, in one embodiment, each positioning plate 23 is provided with a spherical abutment portion 231 on the side facing the fixing plate 22 for abutment and clamping of the watch strap workpiece.

[0033] Furthermore, in one embodiment, multiple clamping components can be configured, such that each set of fixing plates 22 disposed on both sides of the tray 21 is provided with a clamping component that cooperates with it, thereby forming a multi-station clamping structure to meet the batch processing requirements of watch strap workpieces.

[0034] Furthermore, the tray 21 is provided with a mounting groove a corresponding to the clamping component. The mounting groove a extends along the length of the tray 21 and is located between the fixing plates 22 on both sides. Accordingly, the clamping component can be movably fitted into the mounting groove a, thereby ensuring the installation stability of the clamping component.

[0035] Furthermore, in one embodiment, the drive unit 24 may be configured as a drive cylinder, thereby enabling the drive unit 24 to pneumatically activate the corresponding clamping unit 25 to cooperate with the corresponding fixing plate 22 and positioning plate 23, thereby enhancing the clamping response speed, clamping accuracy and stability of the clamping assembly.

[0036] Furthermore, in another embodiment, the driving unit 24 is configured as an inverted frustum structure; correspondingly, each clamping unit 25 has an inclined mating surface at a preset angle on the side surface of the frustum structure to abut against the side surface of the driving unit 24. Based on the above structure, the driving unit 24 can cause the clamping units 25 on both sides to move and engage with the corresponding fixing plate 22 by moving downward, thereby realizing contact driving and support of the clamping units 25.

[0037] Furthermore, the clamping assembly includes two guide shafts 26, which extend along the arrangement direction of the two clamping units 25. Each guide shaft 26 sequentially passes through the inner walls of the two clamping units 25 and the mounting groove a, thereby limiting the reverse movement of each clamping unit 25 and further enhancing the clamping accuracy and stability of the clamping assembly for the watch strap workpiece.

[0038] Furthermore, the clamping assembly also includes a first elastic element 27 and two second elastic elements 28. The first elastic element 27 is disposed at the bottom end of the drive unit 24 to enhance the buffering capacity and support of the drive unit 24 between the mounting groove a. The two second elastic elements 28 are respectively disposed on the two clamping units 25, and each second elastic element 28 abuts against the groove wall of the corresponding side of the mounting groove a, thereby realizing the buffering capacity and support between the clamping unit 25 and the groove wall of the corresponding side of the mounting groove a.

[0039] Furthermore, the bottom end of each positioning plate 23 penetrates through the support plate 21 and extends to the base 10, thereby further enhancing the installation stability between the positioning plate 23 and the support plate 21 based on the mating connection between the base 10 and the support plate 21.

[0040] Furthermore, the base 10 is provided with two guide posts 11 and two positioning pins 12. The two guide posts 11 are located at both ends of the base 10, and each guide post 11 sequentially penetrates the support plate 21 and the cover 30, thereby guiding the installation of the support plate 21 and the cover 30 based on the base 10. The two positioning pins 12 are respectively located on the adjacent sides of the two guide posts 11, and each positioning pin 12 sequentially penetrates the support plate 21 and the cover 30, thereby limiting the installation direction and mating points of the support plate 21 and the cover 30 based on the base 10, so as to improve the mating accuracy between the support plate 21 and the cover 30 and the base 10.

[0041] Furthermore, the cover 30 is provided with a through hole b corresponding to the clamping assembly. When the cover 30 is fitted to the top side of the clamping mechanism 20, the through hole b is provided on the top side of the drive unit 24. In practical applications, the drive unit 24 can be started and locked by passing through the corresponding through hole b with a locking member and driving it.

[0042] Furthermore, the cover 30 is provided with two pressure plates 31 extending along the length of the support plate 21 corresponding to the two rows of fixing plates 22. When the watch strap workpiece to be high-gloss processed is installed on the fixing plate 22 and clamped in place, the two pressure plates 31 cover the top side of several watch strap workpieces, thereby improving the stability of the cover 30 pressing the workpiece. In one embodiment, each pressure plate 31 is set as a flexible plate with a certain buffering performance to prevent damage to the workpiece caused by wall modification.

[0043] Furthermore, support blocks 29 are provided at both ends of the top surface of the support plate 21. When the cover 30 is fitted to the top side of the clamping mechanism 20, the two support blocks 29 can limit the fitting gap between the cover 30 and the support plate 21, so as to avoid the cover 30 from excessively squeezing the workpiece and causing damage.

[0044] Furthermore, in one embodiment, handles 40 are provided on both sides of the cover 30 and the tray 21 to improve the ease of use of the clamp.

[0045] In summary, the CNC high-gloss machining fixture for watch strap beading disclosed in this utility model movably fits the watch strap workpiece to be high-gloss machined between the corresponding fixed plate and positioning plate. Thus, the positioning plate, in conjunction with the fixed plate, houses and positions the watch strap workpiece, while the movable end of the clamping mechanism abuts against the side surface of the watch strap workpiece, thereby achieving stable clamping of the watch strap workpiece. Based on this, the clamping assembly includes a drive unit and two clamping units. The drive unit is movably mounted on the support plate, and the two clamping units are respectively disposed on both sides of the drive unit. Therefore, the drive unit can drive the two clamping units to move towards the corresponding fixed plate, thereby cooperating with the corresponding fixed plate and positioning plate to stably clamp the watch strap workpiece. Compared to existing CNC machining fixtures, the watch strap bead CNC high-gloss machining fixture of this utility model, through the coordinated cooperation between the fixing plate, the positioning plate and the clamping unit, can accurately position the watch strap workpiece while improving the ease of use and clamping stability of the fixture for the watch strap workpiece with a simple and detachable clamping structure. This greatly improves the clamping efficiency of the watch strap workpiece, as well as the high-gloss machining accuracy and yield.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
