After the fixed shaft is fixed, the bottom of the fixed shaft contacts the inner wall of the shell, thereby fixing the shell; by setting a fixed shaft and a positioning hole, etc., the positioning hole cooperates with the connecting shaft on one side to realize the positioning of the shell, and then fix the shell to the base through the fixed shaft, thereby fixing the brake device; at the same time, since the fixed shaft is fixed by pressing the bottom of the shell, the connecting shaft and the end face (i.e. the bottom of the shell) processed in turn can be completely exposed under the fine-turning equipment. Compared with the rough turning tooling fixed on all sides, the machinable area of the end face of the brake device can be increased, which is convenient for subsequent fine-turning.

[0017] 2. By setting the first fixing block, fixing hole, etc., after the fixed shaft passes through the through hole, the fixing rods at both ends of the fixed shaft are threadedly connected to the fixing holes until the fixed shaft contacts the inner wall of the through hole and the connecting tube, and the shell is pressed between the base and the fixed shaft, thereby achieving the fixation of the braking device, with a simple structure and easy operation.

[0018] 3. Position the fixed shaft by setting a second fixed block. When fixing the brake device, pass the fixed shaft through the through hole and the connecting tube so that the fixed shaft contacts the second fixed block. At this time, the fixed shaft also contacts the through hole and the connecting tube. Then the worker rotates the two fixing rods to fix the fixed shaft. Position the fixed shaft by setting the second fixed block so that the fixed shaft remains in a horizontal direction, avoiding inconsistent connection between the fixing rods at both ends and the fixing holes, which causes the fixed shaft to tilt to a certain extent, thereby affecting the fixing effect of the fixed shaft on the brake device.

[0019] 4. By providing the arc-shaped third fixing portion, the contact area between the fixed shaft and the through hole and the connecting cylinder is increased, thereby increasing the fixing effect of the fixed shaft on the braking device. BRIEF DESCRIPTION OF THE DRAWINGS

When the two fixing rods 5 are respectively threadedly connected to the two fixing holes 4b, the bottom of the fixed shaft 2 can contact the inner wall of the through hole 13 and the connecting tube 14.

[0029] Furthermore, when the connecting shaft 15 is engaged with the positioning hole 3 , the outer wall of the housing 12 can be movably fitted to the base 1 .

[0030] Furthermore, a circular second fixing block 6 is provided on the outer wall of the first fixing block 4a, and the height of the second fixing block 6 is greater than the height of the first fixing block 4a. The two ends of the fixed shaft 2 can abut against the top of the second fixing block 6. When the bottom of the fixed shaft 2 abuts against the top of the second fixing block 6, the bottom of the fixed shaft 2 abuts against the inner walls of the through hole 13 and the connecting tube 14.

[0031] Furthermore, a planar first fixing portion 7 is provided at the bottom of the fixing shaft 2 .

[0032] Furthermore, a long rotating rod 8 is provided on the top of the fixed rod 5 .

[0033] Furthermore, a planar second fixing portion 9 is provided on the top of the fixing shaft 2 .

[0034] Furthermore, arc-shaped third fixing parts 10 are symmetrically provided on both sides of the fixed shaft 2. When the bottom of the fixed shaft 2 contacts the top of the second fixed block 6, the bottom of the third fixing part 10 can be movably fitted to the inner wall of the through hole 13 and the connecting tube 14.

[0035] Furthermore, an elastic wear-resistant layer 11 is provided on the inner wall of the first fixing block 4 a.

[0036] Furthermore, when the connecting shaft 15 is engaged with the positioning hole 3 , the housing 12 may contact the inner wall of the elastic wear-resistant layer 11 .

[0037] When the brake device needs to be fine-turned, first engage the connecting shaft 15 at one end of the brake device in the positioning hole 3 until the end surface of the shell 12 contacts the base 1, then pass the fixed shaft 2 through the through hole 13 and the connecting tube 14, and the first fixing portion 7 on the fixed shaft 2 contacts the top of the second fixing block 6, then align the fixing rods 5 at both ends of the fixed shaft 2 with the fixing holes 4b, rotate the rotating rod 8 so that the fixing rod 5 is threadedly connected to the fixing hole 4b, until the rotating rod 8 contacts the second fixing portion 9, and at this time, the bottom of the third fixing portion 10 on the fixed shaft 2 contacts the through hole 13 and the connecting tube 14, thereby achieving Now the shell 12 is fixed; by setting a fixed shaft 2 and a positioning hole 3, the positioning hole 3 cooperates with the connecting shaft 15 on one side to realize the positioning of the shell 12, and then the shell 12 is fixed to the base 1 through the fixed shaft 2, thereby realizing the fixation of the braking device; at the same time, since the fixed shaft 2 is fixed by pressing the bottom of the shell 12, the connecting shaft 15 and the end face (that is, the bottom of the shell 12) processed in turn can be completely exposed under the fine turning equipment. Compared with the rough turning tooling fixed on all sides, the machinable area of the end face of the brake device can be increased, which is convenient for the subsequent fine turning processing.

[0038] By setting the depth of the positioning hole 3, after the connecting shaft 15 is engaged with the positioning hole 3, the end face of the shell 12 can contact the base 1, thereby increasing the contact area between the braking device and the base 1, and increasing the fixing effect of the subsequent fixing shaft 2 on the braking device.

[0040] By setting the second fixing block 6, the fixed shaft 2 is positioned. When fixing the braking device, the fixed shaft 2 is passed through the through hole 13 and the connecting tube 14, so that the fixed shaft 2 is in contact with the second fixing block 6. At this time, the fixed shaft 2 also is in contact with the through hole 13 and the connecting tube 14. Then the worker rotates the two fixing rods 5 to fix the fixed shaft 2. By setting the second fixing block 6 to position the fixed shaft 2, the fixed shaft 2 is kept in a horizontal direction, avoiding inconsistent connection between the fixing rods 5 at both ends and the fixing holes 4b, resulting in a certain tilt of the fixed shaft 2, thereby affecting the fixing effect of the fixed shaft 2 on the braking device.

[0041] By providing the planar first fixing portion 7 , the first fixing portion 7 can increase the contact area between the fixing shaft 2 and the second fixing block 6 , thereby improving the fixing effect between the fixing shaft 2 and the base 1 .

[0042] By providing the arc-shaped third fixing portion 10 , the contact area between the fixing shaft 2 and the through hole 13 and the connecting cylinder 14 is increased, thereby enhancing the fixing effect of the fixing shaft 2 on the braking device.
