[0026] Furthermore, the fixing member 5 includes a first fixing hole 5a horizontally opened on the base 1 and a second fixing hole 5b horizontally opened on the base 1. A first fixing rod 6 is threadedly connected in the first fixing hole 5a, and a second fixing rod 7 is threadedly connected in the second fixing hole 5b. The central axis of the first fixing rod 6 is perpendicular to the central axis of the second fixing rod 7. The second fixing rod 7 is located on the side of the base 1 close to the second positioning groove 4. The ends of the first fixing rod 6 and the second fixing rod 7 can both abut against the outer wall of the housing 18.

[0028] Furthermore, a fourth fixing hole 10 is horizontally opened on the base 1. A fourth fixing rod 11 is threadedly connected in the fourth fixing hole 10. The fourth fixing rod 11 is located directly below the first fixing rod 6.
[0029] Furthermore, a plurality of groups of first positioning rods 12 are symmetrically arranged horizontally on one side of the base 1 close to the first positioning groove 3. The first positioning rods 12 are located in the fixing groove 2. The central axis of the first positioning rod 12 is parallel to the central axis of the second fixing rod 7. The housing 18 can abut against the ends of the first positioning rods 12.
[0030] Further, several groups of second positioning rods 13 are symmetrically arranged along the horizontal direction on the side of the base 1 away from the first fixing rod 6. The second positioning rods 13 are located in the fixing groove 2. The central axis of the second positioning rod 13 is parallel to the central axis of the first fixing rod 6.

[0035] When rough turning the shaft hole of the braking device is required, first place the connecting cylinder 20 on the housing 18 downward in the fixing groove 2, so that the two connecting shafts 21 on the housing 18 are respectively engaged with the first positioning groove 3 and the second positioning groove 4. Then rotate the second rotating rod 15 and the third rotating rod 16, so that the second fixing rod 7 pushes the housing 18, and the third fixing rod 9 pushes one side of the connecting shaft 21, so that the housing 18 approaches and abuts against the first positioning rod 12. Then rotate the first rotating rod 14 and the fourth rotating rod 17, so that the first fixing rod 6 and the fourth fixing rod 11 push the housing 18 to abut against the second positioning rod 13, thereby clamping the braking device. It should be noted that the depth of the fixing groove 2 is less than the distance between the connecting cylinder 20 on the braking device and the shaft hole of the housing 18. Therefore, after the housing 18 is fixed in the fixing groove 2, the shaft hole at one end of the housing 18 is exposed upward, and then rough turning can be carried out; by providing the first positioning groove 3, the fixing groove 2, etc., the first positioning groove 3 and the second positioning groove 4 cooperate with the connecting shaft 21 to realize the preliminary positioning of the housing 18, and then the housing 18 is fixed in the fixing groove 2 through the first fixing rod 6, the second fixing rod 7, etc., so as to realize the fixing of the braking device and facilitate the subsequent rough turning process of the shaft hole.
[0036] By setting the first fixed rod 6, the second fixed rod 7, etc., after placing the connecting cylinder 20 of the braking device downward in the fixed groove 2, the connecting shafts 21 on both sides are respectively engaged in the first positioning groove 3 and the second positioning groove 4, and then the first fixed rod 6 and the second fixed rod 7 are rotated so that the end parts of the first fixed rod 6 and the second fixed rod 7 respectively abut against both sides of the housing 18, thereby clamping the housing 18 between the first fixed rod 6, the second fixed rod 7 and the base 1, realizing the fixation of the braking device. The structure is simple and the operation is convenient.
[0037] By setting the third fixed rod 9, it can abut against the connecting shaft 21, thereby fixing the connecting shaft 21 between the base 1 and the third fixed rod 9, and increasing the fixing effect on the braking device.
[0038] By setting the fourth fixed rod 11 and arranging the fourth fixed rod 11 directly below the first fixed rod 6, the fourth fixed rod 11 can also abut against the housing 18 to fix the housing 18, thereby increasing the contact area with the housing 18 and increasing the fixing effect on the braking device.
[0039] By setting a plurality of first positioning rods 12 and second positioning rods 13, the housing 18 is fixed between the first fixed rod 6 and the first positioning rod 12 and between the second fixed rod 7 and the second positioning rod 13. On the premise of ensuring the fixing effect on the braking device, the contact area between the housing 18 and the base 1 is reduced, thereby reducing the wear of the base 1 caused by vibration during the processing of the housing 18 and prolonging the service life of the tooling.
[0040] By symmetrically arranging the first positioning rods 12 and the second positioning rods 13 on both sides, when a plurality of first positioning rods 12 and second positioning rods 13 abut against both sides of the housing 18, the first fixed rod 6 and the second fixed rod 7 abut against the middle of the housing 18, forming a triangular clamping on two opposite sides of the housing 18, thereby improving the fixing effect on the housing 18.
[0041] By setting the first rotating rod 14, the second rotating rod 15, etc., it is convenient for workers to rotate the first fixed rod 6, the second fixed rod 7, etc., making the operation more convenient.
[0042] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
