Description

Technical Field

[0001] This invention relates to the field of precision machining technology, specifically to a multi-station clamping device for precision machining of watch movement parts. Background Technology

[0002] Watch movements, hailed as the "pinnacle of micromechanical engineering," are composed of hundreds of extremely precise micro-parts. These parts are tiny in size and have complex and diverse geometries (including gears, shafts, plates, balance springs, escapement forks, etc.), and are mostly made of special materials with high hardness and low toughness. During the manufacturing process, the parts not only need to withstand the mechanical forces of milling, drilling, turning, or grinding, but also must maintain extremely high dimensional accuracy and perfect surface integrity (free from scratches, indentations, or deformation). Any minor damage or displacement may lead to functional failure of the movement. As the market's demand for product personalization continues to increase, the styles and functions of watch movements are also constantly being updated, which makes the types and specifications of parts more diverse.

[0003] In existing technologies, the processing and feeding processes are all separate. Missing even one process will affect the operation of the entire device. In addition, there is a lot of manual intervention, resulting in low work efficiency. Furthermore, it cannot perform multi-station processing operations. When processing multiple materials of different sizes, it is necessary to frequently change fixtures, which leads to poor adaptability and low work efficiency. Summary of the Invention

A rotating base is fixedly connected to the top of the worktable, and a fifth motor is fixedly connected to the top of the worktable. This completes the material feeding operation, reducing labor costs and ensuring more stable material feeding without causing human-caused damage, thus improving work quality and efficiency.

[0008] Preferably, the automatic feeding device includes a second lead screw, with a second connecting plate threaded through and connected to the top of the second lead screw. A lifting plate is fixedly connected to one side of the second connecting plate. A limit slide rod is slidably connected through the top of the lifting plate. The output end of a second belt drive mechanism is sleeved and fixedly connected to the portion of the second lead screw located below the second connecting plate. The input end of the second belt drive mechanism is fixedly connected to the drive shaft of a sixth motor. The second lead screw passes through the worktable and is rotatably connected to the worktable. The limit slide rod is fixedly connected to the top of the worktable. The sixth motor is fixedly connected to the top of the worktable, thereby completing the automatic feeding process and improving work efficiency.

[0009] This invention provides a multi-station clamping device for precision machining of watch movement parts. It has the following advantages: 1. This multi-station clamping device for precision machining of watch movement parts, when in use, involves starting a second motor. The drive shaft of the second motor rotates, causing the input end of the first belt drive mechanism to rotate. The rotation of the input end of the first belt drive mechanism causes the output end to rotate. The rotation of the output end of the first belt drive mechanism causes the second rotating column to rotate. The rotation of the second rotating column causes the external meshing gear to rotate. The rotation of the external meshing gear causes the internal meshing gear to rotate. The rotation of the internal meshing gear causes the remaining external meshing gears to rotate. The rotation of the external meshing gears causes the first rack to slide within the second sliding opening and the inner wall of the first sliding groove. The sliding of the first rack causes the first sliding rod to slide within the inner wall of the first sliding opening. The sliding of the first sliding rod causes the first connecting block to move. The movement of the first connecting block drives the multi-station clamping device to move, simultaneously activating the first motor. The drive shaft of the first motor rotates, causing the first driving gear to rotate, which in turn drives the first driven gear to rotate. The driven gear then drives the first rotating column to rotate, which in turn drives the entire shifting device to rotate. This allows the multi-station clamping device to move to a position close to the feeding device for receiving materials. After receiving the materials, it moves back to the processing position for processing. Once processing is complete, the first motor rotates the device to a position close to the recycling bin, and then the first sliding rod moves above the recycling bin for unloading. This automated operation reduces manual intervention and improves work efficiency.

[0010] 2. This multi-station clamping device for precision machining of watch movement parts, in use, when the feeding device places the material on the first and second semi-circular fixed plates, activates the first pneumatic piston rod. The movable end of the first pneumatic piston rod extends, causing the rotating block to move. The movement of the rotating block causes the rotating plate to move. The movement of the rotating plate causes the rotating frame to move. The movement of the rotating frame causes the third sliding block at the bottom of the second driven gear to slide on the third slide rail. The movement of the second driven gear causes the second and third sliding rods to move. The movement of the second and third sliding rods causes the first and second sliding blocks at the bottom to slide on the first and second slide rails. The movement of the rod and the third sliding rod drives the first and second semicircular clamping blocks to move. Under the pressure of the first pneumatic piston rod, when the first semicircular clamping block touches the material with a larger radius, the second driven gear rotates, causing the second and third racks to move. This indirectly makes the first semicircular clamping block clamp the material more tightly and less likely to fall off. The third rack continues to move until the second semicircular clamping block touches the material with a smaller radius and clamps it. Then the first pneumatic piston rod stops working to avoid further squeezing of the material and causing secondary damage. This completes the clamping of materials with different radii at multiple stations, improving the adaptability and working efficiency of the device.

[0011] 3. This multi-station clamping device for precision machining of watch movement parts operates as follows: When the fifth motor is activated, its drive shaft rotates, driving the second drive gear. The second drive gear then drives the third driven gear, which in turn drives the second rotating rod. The third motor is then activated, its drive shaft rotating, driving the first lead screw. The first lead screw then moves the fourth sliding block axially along the lead screw, which in turn moves the second connecting block until the suction cup is directly above the automatic feeding device. At this point, the third and fifth motors stop rotating, and material handling begins. The electric slider is activated, sliding downwards on the fourth slide rail, causing the connecting rod to move downwards. This downward movement of the connecting rod moves the first connecting plate downwards, which in turn moves the second pneumatic piston rod downwards. This downward movement of the second pneumatic piston rod moves the first original connecting disc downwards, which in turn moves the second support downwards. This downward movement of the second support moves the second connecting disc downwards, which in turn moves the fourth motor downwards. The fourth motor moves downward, driving the rotating shaft downward. This downward movement of the rotating shaft drives the rotating disc downward, which in turn drives the suction cup downward. When the suction cup reaches the surface of the material at the top of the automatic feeding device, the second pneumatic piston rod is activated. The movable end of the second pneumatic piston rod extends downward, causing the suction cup to adhere to the material more firmly and prevent it from falling off. After the material is adsorbed, the transfer device is activated. When the transfer device moves the multi-station clamping device closer to the feeding device, the fifth motor is activated again. This rotates the suction cup to a position close to the top of the multi-station clamping device, and then the fourth motor is activated. The drive shaft of the fourth motor rotates, driving the rotating shaft to rotate. This rotation of the rotating disc rotates the materials of different sizes adsorbed on the various suction cups at the bottom to the upper side of the corresponding semi-circular fixing plate on the multi-station clamping device. The material is then lowered, completing the feeding operation. This reduces labor costs, makes feeding more stable, prevents human-caused damage to the material, and improves work quality and efficiency.

[0012] 4. This multi-station clamping device for precision machining of watch movement parts uses a system where materials are first placed between four limiting slide bars for storage. When feeding is required, the sixth motor is activated. The drive shaft of the sixth motor rotates, causing the input end of the second belt drive mechanism to rotate. The input end of the second belt drive mechanism rotates, causing the output end to rotate. The output end of the second belt drive mechanism rotates, causing the second lead screw to rotate. The rotation of the second lead screw causes the second connecting plate to rise along the axis of the second lead screw. The rising of the second connecting plate causes the lifting plate to slide upward on the limiting slide bars. The rising of the lifting plate causes the material to rise to the feeding device's pick-up position, thus completing the automatic feeding process and improving work efficiency.

An internal meshing gear 62 is rotatably connected through the inner wall of the transfer cylinder 61. An external meshing gear 63 meshes with the side of the internal meshing gear 62. A first sliding opening 613 is opened on the top of the transfer cylinder 61. A second sliding opening 613 is opened on the inner wall of the first sliding opening 613. The moving port 64 has a first sliding rod 65 slidably connected to the inner wall of the first sliding port 613. A first rack 66 is fixedly connected to one side of the first sliding rod 65. The first rack 66 is slidably connected to the second sliding port 64 and meshes with an external meshing gear 63. A second rotating column 67 is rotatably connected through the top of the external meshing gear 63. The second rotating column 67 passes through the bottom of the inner wall of the shifting box 61 and is fixedly connected to the output end of the first belt drive mechanism 610. A second motor 611 is fixedly connected to the input end of the first belt drive mechanism 610. The motor 611 is fixedly connected to the bottom of the shifting box 61. A support ring 68 is fixedly connected to the bottom of the inner wall of the shifting box 61. A first sliding groove 69 is opened on the top of the support ring 68. The first sliding rod 65 and the first rack 66 are both slidably connected to the first sliding groove 69. A first connecting block 612 is fixedly connected to the top of the first sliding rod 65. The shifting box 61 is fixedly connected to the top of the first rotating column 2. The first connecting block 612 is fixedly connected to the bottom of the multi-station clamping device 7. Multiple sets of external meshing gears 63 are evenly distributed on one side of the internal meshing gears 62.

[0017] In use, the second motor 611 is started. The drive shaft of the second motor 611 rotates, causing the input end of the first belt drive mechanism 610 to rotate. The rotation of the input end of the first belt drive mechanism 610 causes the output end to rotate. The rotation of the output end of the first belt drive mechanism 610 causes the second rotating column 67 to rotate. The rotation of the second rotating column 67 causes the external meshing gear 63 to rotate. The rotation of the external meshing gear 63 causes the internal meshing gear 62 to rotate. The rotation of the internal meshing gear 62 causes the remaining external meshing gears 63 to rotate. The rotation of the external meshing gears 63 causes the first rack 66 to slide on the inner wall of the second sliding opening 64 and the first sliding groove 69. The sliding of the first rack 66 causes the first sliding rod 65 to slide on the inner wall of the first sliding opening 613. The sliding of the first sliding rod 65 causes the first connecting block 612 to move. The first connecting block 612 moves, driving the multi-station clamping device 7 to move. At the same time, the first motor 5 is started. The drive shaft of the first motor 5 rotates, driving the first drive gear 4 to rotate. The first drive gear 4 rotates, driving the first driven gear 3 to rotate. The first driven gear 3 rotates, driving the first rotating column 2 to rotate. The rotation of the first rotating column 2 can drive the entire transfer device 6 to rotate, so that the multi-station clamping device 7 can move to a position close to the feeding device 8 to receive materials. After receiving the materials, it moves back to the processing position for processing. After processing is completed, it can be driven by the rotation of the first motor 5 to a position close to the recycling box 10. Then the first sliding rod 65 moves to the top of the recycling box 10 to unload the materials. This can realize automated operation, reduce manual intervention, and improve work efficiency.

[0018] Please see Figures 1-6The present invention provides a technical solution: a multi-station clamping device 7 includes a supporting base plate 71, with a first slide rail 72, a second slide rail 73, and a third slide rail 711 fixedly connected to the top of the supporting base plate 71 respectively. A first sliding block 74 is slidably connected to the inner wall of the first slide rail 72, a second sliding block 75 is slidably connected to the inner wall of the second slide rail 73, and a third sliding block 712 is slidably connected to the inner wall of the third slide rail 711. A fixed base 713 is fixedly connected to the top of the third sliding block 712, and a first rotating rod 714 is passed through and fixedly connected to the top of the fixed base 713. A second driven gear 710 is fitted and rotatably connected to the first sliding block 74. A second sliding rod 76 is fixedly connected to the top of the first sliding block 74. A first semi-circular clamping block 721 is fixedly connected to one end of the second sliding rod 76. A third sliding rod 77 is fixedly connected to the top of the second sliding block 75. A second semi-circular clamping block 722 is fixedly connected to one end of the third sliding rod 77. A second rack 78 is fixedly connected to the side of the second sliding rod 76. A third rack 79 is fixedly connected to the side of the third sliding rod 77 near the second sliding rod 76. The second rack 78 meshes with one side of the second driven gear 710. The three-tooth rack 79 meshes with one side of the second driven gear 710. A rotating frame 715 is rotatably connected to the portion of the first rotating rod 714 located above the second driven gear 710. A rotating plate 716 is rotatably connected to the end of the rotating frame 715 away from the first rotating rod 714. A rotating block 717 is rotatably connected to the bottom of the rotating frame 715. The movable end of the first pneumatic piston rod 718 is fixedly connected to one side of the rotating block 717. A first bracket 719 is fixedly connected to the fixed end of the first pneumatic piston rod 718. The first bracket 719 is fixedly connected to the top of the support base plate 71. The top of 71 is fixedly connected to a material feeding base 720 on one side of the first slide rail 72. The top of the material feeding base 720 is fixedly connected to a first semi-circular fixing plate 723 and a second semi-circular fixing plate 724. The support base plate 71 is fixedly connected to the top of the first connecting block 612. The rotating frame 715 is symmetrically arranged on both sides of the rotating plate 716. The radius of the first semi-circular clamping block 721 is larger than that of the second semi-circular clamping block 722. The radius of the first semi-circular clamping block 721 is the same as that of the first semi-circular fixing plate 723. The radius of the second semi-circular clamping block 722 is the same as that of the second semi-circular fixing plate 724.

[0019] In use, when the feeding device 8 places the material on the first semi-circular fixed plate 723 and the second semi-circular fixed plate 724, the first pneumatic piston rod 718 is activated. The movable end of the first pneumatic piston rod 718 extends, causing the rotating block 717 to move. The movement of the rotating block 717 causes the rotating plate 716 to move. The movement of the rotating plate 716 causes the rotating frame 715 to move. The movement of the rotating frame 715 causes the third sliding block 712 at the bottom of the second driven gear 710 to slide on the third slide rail 711. The movement of the second driven gear 710 causes the second sliding rod 76 and the third sliding rod 77 to move. The movement of the second sliding rod 76 and the third sliding rod 77 causes the first sliding block 74 and the second sliding block 75 at the bottom to slide on the first slide rail 72 and the second slide rail 73. The movement of sliding rod 76 and third sliding rod 77 drives the first semicircular clamping block 721 and the second semicircular clamping block 722 to move. Under the compression of the first pneumatic piston rod 718, when the first semicircular clamping block 721 touches the material with a larger radius, the second driven gear 710 rotates, causing the second rack 78 and the third rack 79 to move. This indirectly makes the first semicircular clamping block 721 clamp the material more tightly and less likely to fall off. The third rack 79 will continue to move until the second semicircular clamping block 722 touches the material with a smaller radius and clamps it. Then the first pneumatic piston rod 718 stops working to avoid further compression of the material and secondary damage to the material. This completes the clamping of materials with different radii at multiple stations, improving the adaptability and working efficiency of the device.

A rotating disc 820 is fixedly connected to the bottom of the rotating shaft 819. A suction cup 821 is fixedly connected to the bottom of the rotating disc 820. A rotating base 81 is fixedly connected to the top of the worktable 1. A fifth motor 824 is fixedly connected to the top of the worktable 1.

[0021] In operation, the fifth motor 824 is started. The drive shaft of the fifth motor 824 rotates, driving the second drive gear 823 to rotate. The rotation of the second drive gear 823 drives the third driven gear 822 to rotate. The rotation of the third driven gear 822 drives the second rotating rod 82 to rotate. The third motor 84 is then started. The drive shaft of the third motor 84 rotates, driving the first lead screw 86 to rotate. The rotation of the first lead screw 86 drives the fourth sliding block 87 to move axially on the first lead screw 86. The movement of the fourth sliding block 87 drives the second connecting block 88 to move until the suction cup 821 moves directly above the automatic feeding device 9, at which point the third motor 84 and the fifth motor 824 stop rotating. The machine moves, then begins to pick up materials. The electric slider 811 is activated, sliding downwards on the fourth slide rail 810, causing the connecting rod 812 to move downwards. The downward movement of the connecting rod 812 causes the first connecting plate 813 to move downwards. The downward movement of the first connecting plate 813 causes the second pneumatic piston rod 814 to move downwards. The downward movement of the second pneumatic piston rod 814 causes the first connecting circular plate 815 to move downwards. The downward movement of the first connecting circular plate 815 causes the second bracket 816 to move downwards. The downward movement of the second bracket 816 causes the second connecting circular plate 817 to move downwards. The downward movement of the second connecting circular plate 817 causes the fourth motor 81... 8. Moving downwards, the fourth motor 818 moves downwards, driving the rotating shaft 819 downwards. The rotating shaft 819 moves downwards, driving the rotating disc 820 downwards. The rotating disc 820 moves downwards, driving the suction cup 821 downwards. When it reaches the surface of the material at the top of the automatic feeding device 9, the second pneumatic piston rod 814 is activated. The movable end of the second pneumatic piston rod 814 extends and moves downwards, driving the suction cup 821 downwards to adsorb the material, making it more firmly adsorbed and less likely to fall off. After adsorbing the material, the transfer device 6 is activated. The transfer device 6 moves the multi-station clamping device 7 to a position close to the feeding device 8, and then the fifth motor is activated again. After the suction cup 821 is rotated to a position close to the multi-station clamping device 7, the fourth motor 818 is started. The drive shaft of the fourth motor 818 rotates, driving the rotating shaft 819 to rotate. The rotating shaft 819 rotates, driving the rotating disk 820 to rotate. The rotating disk 820 rotates, thereby rotating the materials of different sizes adsorbed on the various suction cups 821 at the bottom to the upper side of the corresponding semi-circular material fixing plate on the multi-station clamping device 7. Then the materials are put down, thus completing the material feeding operation. This reduces labor costs, makes the feeding more stable, and prevents human-caused damage to the materials, improving work quality and efficiency.

[0022] Please see Figures 1-9The present invention provides a technical solution: an automatic feeding device 9 includes a second lead screw 91, a second connecting plate 92 is threaded through and connected to the top of the second lead screw 91, a lifting plate 93 is fixedly connected to one side of the second connecting plate 92, a limiting slide rod 94 is slidably connected through the top of the lifting plate 93, the output end of a second belt drive mechanism 95 is sleeved and fixedly connected to the part of the second lead screw 91 located below the second connecting plate 92, the input end of the second belt drive mechanism 95 is fixedly connected to the drive shaft of a sixth motor 96, the second lead screw 91 passes through the worktable 1 and is rotatably connected to the worktable 1, the limiting slide rod 94 is fixedly connected to the top of the worktable 1, and the sixth motor 96 is fixedly connected to the top of the worktable 1.

[0023] In use, the material is first placed between the four limiting slide bars 94 for storage. When feeding is required, the sixth motor 96 is started. The drive shaft of the sixth motor 96 rotates, which drives the input end of the second belt drive mechanism 95 to rotate. The rotation of the input end of the second belt drive mechanism 95 drives the output end to rotate. The rotation of the output end of the second belt drive mechanism 95 drives the second lead screw 91 to rotate. The rotation of the second lead screw 91 drives the second connecting plate 92 to rise along the axis of the second lead screw 91. The rise of the second connecting plate 92 drives the lifting plate 93 to slide upward on the limiting slide bars 94. The rise of the lifting plate 93 drives the material to the feeding device 8 to pick up the material, thus completing the automatic feeding process and improving work efficiency.
