[0018] This specific embodiment is a fourth-axis device for metal bracelets and rings, and its structural schematic diagram is as Figures 1-2 shown, including a module bracket 6, a planetary reducer 2 is assembled on one side of the module bracket 6, an A-axis motor 1 is assembled on the planetary reducer 2, the output end of the planetary reducer 2 is movably connected to the module bracket 6 through a bearing, the output end of the planetary reducer 2 passes through the inner ring of the bearing and extends into the module bracket 6, a link 3 is assembled on the output end of the planetary reducer 2, a sleeve clamp 4 is arranged in the module bracket 6, the sleeve clamp 4 is assembled on the link 3, a tool setting gauge 5 is installed on the inner wall of one side of the module bracket 6, and a tool clamp 8 is assembled on one side of the module bracket 6.

[0019] The A-axis motor 1, the planetary reducer 2, the tool setting gauge 5, and the link 3 in this technical solution are common driving devices and accessories on the market and belong to common general knowledge, so they are not described in detail in this technical solution.

[0020] Among them, the rear side wall of the module bracket 6 is provided with evenly distributed mounting holes 7. There are four mounting holes 7. Through the multiple mounting holes 7, the module bracket 6 can be stably fixed in the place where it is needed. Moreover, the multiple mounting holes 7 prevent the module bracket 6 from rotating after being stressed, improving the stability of use.

[0021] In addition, the module bracket 6 is U-shaped. The inner wall of the module bracket 6 is convex near the bottom. The U-shaped module bracket 6 can increase the stability of the module bracket 6 when placed and used. And the convex part increases the contact area with the plane, while facilitating the operation of the device.

[0022] Among them, the tool fixture 8 is installed through the module bracket 6 with a knob 9. The outer wall of the knob 9 is provided with an anti-slip setting. Through the anti-slip setting, it can be ensured that the knob 9 will not slip when rotated forcefully, improving the convenience of use.

[0023] In addition, the sleeve fixture 4 is composed of multiple arc-shaped clamping blocks. And there are six arc-shaped clamping blocks. The arc-shaped clamping blocks are arranged in a circular array. Through the arc-shaped clamping blocks arranged in a circular array, when clamping the metal bracelet, the clamping force on the metal bracelet is more uniform, preventing the metal bracelet from being scratched.

[0024] Among them, a placement groove 10 is opened on one side of the sleeve fixture 4. The placement groove 10 is circular. Through the placement groove 10, the metal bracelet can be quickly placed in the central position, playing a role in limiting.

[0025] Working principle: When this technical solution is used, first fix the module bracket 6. The module bracket 6 is fixed in the place where it is needed by passing a bolt fixing part through the mounting hole 7. Next, power it on and debug it. After the debugging is completed, it can be used normally. First, place the metal bracelet to be processed in the placement groove 10, and control the A-axis motor 1 to drive the planetary reducer 2 to rotate. The planetary reducer 2 controls the multiple sleeve fixtures 4 to open or close through the link 3. When the sleeve fixture 4 opens, it clamps and fixes the inner ring of the metal bracelet. When the sleeve fixture 4 closes, it clamps and fixes the outer ring of the metal bracelet. After the metal bracelet is fixed, rotate the tool fixture 8 through the knob 9. Install a suitable tool on the tool fixture 8 and tighten the knob 9 to fix the tool. Next, perform tool setting through the tool setter 5 to make the position of the tool more accurate and improve the precision of processing. The above operations can effectively solve the problem that the metal bracelet is easily scratched.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above embodiments are preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
