[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] Example:

[0033] See also Figure 1 and Figure 2 This embodiment discloses an angle adjustment device for processing micro-texture on the back face of a ball-end milling cutter, comprising a base 1, a bracket 2, a clamping assembly and a positioning assembly. The top surface of the base 1 is a planar structure, the bracket 2 is an L-shaped structure, one end of the bracket 2 is rotatably connected to the top surface of the base 1, and the end of the bracket 2 is arranged in a horizontal direction and parallel to the top surface of the base 1.

[0034] The other end of the bracket 2 is arranged in the vertical direction, and a clamping assembly and a positioning assembly are arranged on this end of the bracket 2, wherein the positioning assembly is arranged at the rear side of the clamping assembly.

[0035] Specifically, the clamping assembly includes a caliper 3 and a first motor 4. The middle part of the caliper 3 is a hollow structure, through which a ball-end milling cutter can pass, and the caliper 3 can clamp the ball-end milling cutter. The output shaft of the first motor 4 is connected to the caliper 3 by power, and the caliper 3 can be driven to rotate by the first motor 4.

[0036] The positioning component has a telescopic end, which can move closer to or away from the clamping component.

[0037] In this embodiment, the ball-end milling cutter is clamped on the caliper 3, and then the tail end of the ball-end milling cutter is positioned by the positioning assembly to ensure that the center of the ball head of the ball-end milling cutter is located on the rotating shaft of the bracket 2. The caliper 3 and the ball-end milling cutter are then driven to rotate by the first motor 4 to adjust the side of the ball-end milling cutter to be processed to a directional state.

[0038] Then the position of the ball-end milling cutter can be adjusted by rotating the bracket 2. Since the bracket 2 is an L-shaped structure, the center of the ball end of the ball-end milling cutter is kept in the same position during the rotation, thereby facilitating processing.

[0039] In this technical solution, the ball-end milling cutter can complete multi-dimensional rotation, thereby simplifying the control program of the fiber laser during the processing.

[0042] In this embodiment, by arranging a gear box 5 between the first motor 4 and the caliper 3, the caliper 3 can have a self-locking function, so that the first motor 4 drives the caliper 3 and the ball-end milling cutter to rotate a certain angle and the angle can be maintained.

[0043] In another specific embodiment:

[0044] The positioning assembly includes a support plate 6, a slide plate 7, a baffle plate 8, a vertical plate 9 and a screw 10. Specifically, one end of the support plate 6 is fixedly set at the top end of the vertically set end of the bracket 2, and the other end of the support plate 6 is set in the horizontal direction and extends to the end away from the gear box 5.

[0045] A slide groove is arranged on the top surface of the support plate 6 , and the length direction of the slide groove is consistent with the length direction of the support plate 6 . At the same time, a slide plate 7 is slidably arranged in the slide groove, and the length direction of the slide plate 7 is also the same as the length direction of the support plate 6 .

[0046] A vertical plate 9 is respectively arranged at both ends of the slide plate 7, and the screw rod 10 is rotatably arranged on the two vertical plates 9. The baffle plate 8 is slidably arranged on the slide plate 7, and a threaded hole matching the screw rod 10 is provided on the baffle plate 8.

[0047] Preferably, a round handle is provided on the end of the screw rod 10 away from the gear box 5 .

[0048] In this embodiment, the distance between the baffle plate 8 and the gear box 5 can be adjusted by sliding the slide plate 7 and rotating the screw rod 10 on the vertical plate 9, so as to determine the position of the tail of the ball-end milling cutter in this way, and then the ball center of the ball-end milling cutter of different sizes can be controlled on the rotating shaft of the bracket 2 and the base 1. According to the working principle of this embodiment, the baffle plate 8 is the telescopic end of the positioning assembly.

[0049] In another specific embodiment:

[0050] A second motor 11 is mounted on the base 1 , and an output shaft of the second motor 11 is connected to an end of the bracket 2 and is used to drive the bracket 2 to rotate.

[0051] In another specific embodiment:

[0052] The base 1 is a semicircular structure, and an arc-shaped support member 12 is arranged on the base 1, and the top of the support member 12 is in sliding contact with the bracket 2. The base 1 has an arc-shaped guide groove 13, and the bottom of the bracket 2 is provided with a guide rod slidably arranged in the guide groove 13.
