Abstract
Description
Technical Field
[0001] This application relates to the field of watchmaking technology, and more specifically, to a multi-station chuck mounting bracket and chuck mechanism. Background Technology
[0002] A CNC rotary table, also known as a CNC turntable, is a common component of CNC milling machines. It is often used as a servo axis of a CNC milling machine, namely the C-axis of a vertical CNC milling machine or the B-axis of a horizontal CNC milling machine.
[0003] Application No. 201810828875.9 discloses a five-axis platform for machining watch cases using a pin cantilever, relating to the field of CNC rotary table technology. This five-axis platform for machining watch cases includes a hollow four-axis mechanism, a five-axis cantilever, a servo motor, a pin mechanism, a rotary chuck, a speed change device, a fixture positioning plate, and a watch case fixture.
[0004] Although the aforementioned pin-cantilever five-axis platform can improve the rotary positioning mechanism on the CNC turntable and enhance the positioning accuracy of watchmaking, its drawback is that it is not suitable for simultaneously grinding and polishing multiple watch cases, resulting in low machine efficiency. Therefore, it is necessary to design a multi-station watch polishing chuck.
[0005] A multi-station watch polishing chuck includes a base mounting plate, drive cylinders, pull rods, clamps, and rotary motors. The pull rods are mounted on the base mounting plate, with a drive cylinder on one side and a rotary motor on the other. The pull rods are connected to both the drive cylinders and the rotary motors. The end of the pull rods is connected to the clamps. The drive cylinders drive the pull rods to rise and fall, causing the clamps to clamp and release the watch case. The rotary motors drive the clamps to rotate. However, a multi-station watch polishing chuck requires multiple pull rods, multiple drive cylinders, and multiple rotary motors. Multiple drive cylinders are mounted on the same side of the base mounting plate, and multiple rotary motors are mounted on the other side. This can easily lead to uneven load distribution on the base mounting plate, poor stability, and even deformation of the base mounting plate, thus affecting the polishing accuracy of the watch workpieces.
[0006] Therefore, existing technologies need to be improved. Utility Model Content

[0048] Example 1:
[0049] Please see Figure 1 and Figure 2 This embodiment provides a multi-station chuck mounting bracket, which includes: a bracket body 100 and a plurality of first mounting portions 600. The bracket body 100 includes a base mounting plate 210, and the first mounting portions 600 are disposed on the base mounting plate 210 and are used to mount a clamp 500. Figure 5 As shown in the figure, the first mounting part 600 has a front end 601 and a rear end 602. The front end 601 is provided with a rotary motor 540 for the clamp 500, and the rear end 602 is provided with a drive cylinder 550 for the clamp 500. The two adjacent first mounting parts 600 are alternately arranged front and rear.
[0050] In this embodiment, please refer to Figure 2 and Figure 5 As shown, the multi-station chuck mounting bracket is used to mount a fixture 500, which can be applied to the processing of watch cases. For example, the fixture 500 includes a pull rod 510, a clamping head 520, a flange 530, a rotary motor 540, and a drive cylinder 550. The flange 530 is mounted on the front of the base mounting plate 210, and the drive cylinder 550 and the rotary motor 540 are mounted on the back of the base mounting plate 210. The pull rod 510 passes through the base mounting plate 210 and is embedded in the flange 530. The end of the pull rod 510 is connected to the clamping head 520, which is used to clamp the watch case. The pull rod 510 is driven by both the drive cylinder 550 and the rotary motor 540. The drive cylinder 550 drives the pull rod 510 to move up and down, causing the pull rod 510 to move the clamping head 520 up and down. The rotary motor 540 drives the pull rod 510 to rotate, causing the pull rod 510 to rotate the clamping head 520. The clamp head 520 has a clamping jaw. When the pull rod 510 drives the clamp head 520 to insert downward into the flange 530, the clamping jaw abuts against the flange 530, causing the clamping jaw to retract and release the watch case. When the watch case is placed on the clamping jaw and the pull rod 510 moves upward, the clamping jaw disengages from the flange 530, and the clamping jaw opens to clamp the watch case.
[0051] To ensure a tighter fit between the clamps 500 on the base mounting plate 210 and reduce its length, a rotary motor 540 is mounted on the front of the pull rod 510, and a drive cylinder 550 is mounted on the rear. Since the base mounting plate 210 has multiple clamps 500, it requires multiple rotary motors 540 and drive cylinders 550. The rotary motors 540 are connected to the pull rod 510 via accelerators and splines, while the drive cylinders 550 are directly connected. The weight of the rotary motors 540 and accelerators differs from that of the drive cylinders 550, resulting in uneven load distribution between the front and rear of the base mounting plate 210. A higher number of clamps 500 on the base mounting plate 210 exacerbates this uneven load distribution, leading to poor stability and increased susceptibility to deformation. Deformation of the base mounting plate 210 will affect the machining accuracy of the watch case.
[0052] Therefore, in this embodiment, by alternating the front and rear arrangements of two adjacent first mounting parts 600, the driving cylinder 550 and the rotary motor 540 are alternately mounted on the base mounting plate 210, so that the load on the base mounting plate 210 is evenly distributed, improving the stability of the base mounting plate 210, making it less prone to deformation, and improving the processing accuracy and efficiency of the chuck mechanism.
[0053] Specifically, please refer to Figure 3The first mounting part 600 includes: a first through hole 610, a second through hole 620 and a third through hole 630. The first through hole 610 is formed in the base mounting plate 210 and is used to install the pull rod 510 of the clamp 500. The second through hole 620 is formed in the base mounting plate 210 and is located in front of the first through hole 610. The second through hole 620 is used to install the rotary motor 540. The third through hole 630 is formed in the base mounting plate 210 and is located in rear of the first through hole 610. The third through hole 630 is used to install the drive cylinder 550.
[0054] In this embodiment, the pull rod 510 of the clamp 500 passes through the first through hole 610, the second through hole 620 is located in front of the first through hole 610, the rotary motor 540 passes through the second through hole 620 and is connected to the reducer, the reducer can be connected to the pull rod 510 through a spline, the third through hole 630 is located behind the first through hole 610, the third through hole 630 can be set as a bolt hole, the base mounting plate 210 can fix the drive cylinder 550 through the bolt hole.
[0055] Specifically, please refer to Figure 3 The first through hole 610 is located on the central axis of the base mounting plate 210. This allows the fixture 500 to be mounted on the central axis of the base mounting plate 210, which helps to improve the stability of the base mounting plate 210 and improve machining accuracy.
[0056] Specifically, please refer to Figure 1 The base mounting plate 210 is provided with four first mounting parts 600. That is, the base mounting plate 210 can be provided with four clamps 500, and the four clamps 500 can simultaneously clamp four watch cases for processing, which can improve work efficiency.
[0057] Specifically, please refer to Figure 3 The second through holes 620 of the first and third first mounting parts 600 are located on the front side of the base mounting plate 210, and the third through holes 630 of the second and fourth first mounting parts 600 are also located on the front side of the base mounting plate 210. This allows the rotary motor 540 and the drive cylinder 550 to alternate back and forth, resulting in a uniform load distribution on the base mounting plate 210, improving its stability, reducing deformation, and enhancing the machining accuracy and efficiency of the chuck mechanism.
[0058] Specifically, please refer to Figure 1Several first mounting parts 600 are arranged at equal intervals. This ensures that the clamps 500 of the base mounting plate 210 are also arranged at equal intervals, that is, the displacement of two adjacent clamps 500 is consistent, and the distance between the watch cases on two adjacent clamps 500 is also consistent, so as to realize the synchronous processing of several watch cases and improve the working efficiency of the chuck mechanism.
[0059] Specifically, please refer to Figure 1 The bracket body 100 also includes: a first U-shaped base 300, a second U-shaped base 200, and a drive motor 400. The first U-shaped base 300 has a U-shaped groove. The second U-shaped base 200 includes a base mounting plate 210. The second U-shaped base 200 is embedded in the U-shaped groove of the first U-shaped base 300 and is rotatably connected to the first U-shaped base 300. The drive motor 400 is disposed on the first U-shaped base 300. The drive shaft of the drive motor 400 is drivenly connected to the second U-shaped base 200. The drive motor 400 is used to drive the second U-shaped base 200 to rotate.
[0060] In this embodiment, the second U-shaped base 200 is embedded within the first U-shaped base 300 and rotatably connected to the first U-shaped base 300. The drive motor 400 is driven by the second U-shaped base 200, and the drive motor 400 can drive the second U-shaped base 200 to rotate, thereby enabling the clamp 500 on the base mounting plate 210 to swing back and forth. The structure is stable and highly safe. For example, during the grinding and polishing process of a watch case, the drive motor 400 drives the second U-shaped base 200 to rotate, causing the clamp 500 to swing the watch case to adjust the angle of the watch case.
[0061] Specifically, please refer to Figure 3 The first U-shaped base 300 includes: a first base plate 310, a first side plate 320, a second side plate 330, a first connector 340, and a second connector 350. The first side plate 320 is located on the left side of the first base plate 310, and the second side plate 330 is located on the right side of the first base plate 310. The first side plate 320, the first base plate 310, and the second side plate 330 are connected in sequence to form a groove structure. The first connector 340 is located on the first side plate 320 and is used to connect the first side plate 320 and the second U-shaped base 200. The second connector 350 is located on the second side plate 330 and is used to connect the second side plate 330 and the second U-shaped base 200.
[0062] In this embodiment, the first side plate 320 is rotatably connected to the left side of the second U-shaped base 200 via the first connector 340, and the second side plate 330 is rotatably connected to the right side of the second U-shaped base 200 via the second connector 350. The structure is stable and the movement is reliable, enabling the rotation of the second U-shaped base 200, so that the clamp 500 on the base mounting plate 210 can adjust the angle.
[0063] Specifically, please refer to Figure 4 The second U-shaped base 200 also includes: a third side plate 220, a fourth side plate 230, a third connector 240, and a fourth connector 250. The third side plate 220 is located on the left side of the base mounting plate 210, and the second side plate 330 is located on the right side of the base mounting plate 210. The first side plate 320, the first base bottom plate 310, and the second side plate 330 are connected in sequence to form a groove structure. The third connector 240 is located on the third side plate 220 and is rotatably connected to the first connector 340. The fourth connector 250 is located on the fourth side plate 230 and is rotatably connected to the second connector. The fourth connector 250 is also connected to the drive shaft.
[0064] In this embodiment, a third side plate 220 is provided on one side of the base mounting plate 210, and a fourth side plate 230 is provided on the other side. A third connector 240 is provided on the third side plate 220, and a fourth connector 250 is provided on the fourth side plate 230. The third connector 240 is connected to the first connector 340, and the fourth connector 250 is connected to the second connector. The fourth connector 250 is also connected to the drive motor 400. The drive motor 400 can drive the fourth connector 250 to rotate along the second connector, causing the second U-shaped base 200 to rotate along the first U-shaped base 300, thereby causing the clamp 500 on the base mounting plate 210 to rotate, so as to adjust the angle of the watch case on the clamp 500.
