[0024] The present invention provides a rough turning tool for the end face and the outer circle of the shaft of the braking basic device of the train braking system, as Figures 1 to 2 shown, including a base 1, a first fixing block 2 arranged on the base 1 in the vertical direction, and a second fixing block 3 arranged on the base 1 in the vertical direction. The second fixing block 3 is perpendicular to the first fixing block 2. An L-shaped third fixing block 4 is arranged on the base 1. A fixing gap with a rectangular cross-section is formed among the first fixing block 2, the second fixing block 3, and the third fixing block 4. A fixing piece 5 for fixing the housing 17 is arranged on the third fixing block 4.
[0025] Further, the third fixing block 4 includes a first fixing part 4a parallel to the first fixing block 2 and a second fixing part 4b parallel to the second fixing block 3. The fixing piece 5 includes a plurality of first fixing holes 5a horizontally opened on the first fixing part 4a and a plurality of second fixing holes 5b horizontally opened on the second fixing part 4b. A first fixing rod 6 is threadedly connected in the first fixing hole 5a, and the end of the first fixing rod 6 can abut against the outer wall of the housing 17. A second fixing rod 7 is threadedly connected in the second fixing hole 5b, and the end of the second fixing rod 7 can abut against the housing 17 or the end of a connecting cylinder 19.
[0026] Further, the second fixing block 3 can be movably attached to the end of the connecting cylinder 19, and the second fixing rod 7 can abut against the outer wall of the housing 17.
[0027] Furthermore, a positioning hole 8 is formed in the base 1, and the diameter of the positioning hole 8 is smaller than the diameter of a connecting shaft 20. When the central axis of the positioning hole 8 coincides with the central axis of the connecting shaft 20, the outer wall of the housing 17 is movably attached to the first fixing block 2, and at the same time, the end of the connecting cylinder 19 is movably attached to the second fixing block 3.
[0028] Furthermore, a detachable fourth fixing block 9 is provided on one side of the first fixing block 2 close to the third fixing block 4, and a detachable fifth fixing block 10 is provided on one side of the second fixing block 3 close to the third fixing block 4.
[0029] Furthermore, a first fixing groove 11 is formed in the first fixing block 2 in the vertical direction, a second fixing groove 12 is formed in the second fixing block 3 in the vertical direction, a first positioning block 13 that matches the first fixing groove 11 is provided on one side of the fourth fixing block 9 close to the first fixing block 2, and a second positioning block 14 that matches the second fixing groove 12 is provided on one side of the fifth fixing block 10 close to the second fixing block 3.
[0030] Furthermore, the cross-sections of both the first fixing groove 11 and the second fixing groove 12 are T-shaped.
[0031] Furthermore, the number of both the first fixing holes 5a and the second fixing holes 5b is 2, and the two second fixing holes 5b are diagonally distributed on the second fixing portion 4b.
[0032] Furthermore, a long strip-shaped first rotating block 15 is provided at the end of the first fixing rod 6.
[0033] Furthermore, a long strip-shaped second rotating block 16 is provided at the end of the second fixing rod 7.
[0034] When rough turning the end face of the braking device and the outer circle of the shaft (i.e., the outer wall of the connecting shaft 20), first fix the tooling on the rough turning equipment through the base 1. Then, align the connecting shaft 20 at one end of the braking device downward with the positioning hole 8 and place it on the base 1. After that, rotate the first fixing rod 6 and the second fixing rod 7 so that the first fixing rod 6 and the second fixing rod 7 respectively abut against the outer wall of the housing 17 and push the housing 17 against the first fixing block 2, and the end of the connecting cylinder 19 abuts against the second fixing block 3, thereby clamping the housing 17 between the first fixing rod 6 and the first fixing block 2 and between the second fixing rod 7 and the second fixing block 3, realizing the fixation of the four sides of the braking device. After that, the rough turning equipment can be used to rough turn the end face of the braking device and the upward-facing outer circle of the shaft. After the rough turning is completed, the first fixing rod 6 and the second fixing rod 7 can be rotated to turn the completed connecting shaft 20 downward, and then the connecting shaft 20 on the other side can be rough turned; by providing the first fixing block 2 and the second fixing block 3, etc., the fixing member 5, the first fixing block 2, and the second fixing block 3 fix the four sides of the braking device, thereby realizing the fixation of the braking device and facilitating the rough turning of the connecting shaft 20 on the other side and the end face where the connecting shaft 20 is located.
[0035] By providing the first fixing rod 6, the second fixing rod 7, etc., rotating the first fixing rod 6 and the second fixing rod 7 can realize the clamping and fixation of the four sides of the braking device. After that, the connecting shaft 20 and the end face of the braking device can be rough machined. The structure is simple and the operation is convenient.
[0036] By making the end of the connecting cylinder 19 abut against the second fixing block 3, the second fixing rod 7 can abut against the side of the housing 17 provided with the through hole 18. Compared with the second fixing rod 7 abutting against the end of the connecting cylinder 19 (the thickness of the connecting cylinder 19 is less than the diameter of the second fixing rod 7), the contact area between the second fixing rod 7 and the braking device can be greatly increased, thereby increasing the fixing effect on the braking device.
[0037] By providing the positioning hole 8, when the worker places the housing 17, just align the connecting shaft 20 at one end with the positioning hole 8 and place it on the positioning hole 8. At this time, the preliminary positioning of the position of the housing 17 can be realized, and then the housing 17 can be fixed around by the fixing member 5; by providing the positioning hole 8, the preliminary positioning of the housing 17 is realized, which is convenient for the worker to place the housing 17 in the correct position and avoid the worker placing the housing 17 in the wrong position, which may affect the subsequent rough turning process of the connecting shaft 20.
[0038] By setting detachable fourth fixing blocks 9, fifth fixing blocks 10, etc., the braking device is clamped between the fourth fixing block 9 and the first fixing rod 6, and between the fifth fixing block 10 and the second fixing rod 7. After rough turning, due to the vibration of the housing 17, the fourth fixing block 9, the fifth fixing block 10, the first fixing rod 6, and the second fixing rod 7 will be worn after a period of use. At this time, the clamping effect of the braking device can be ensured by directly replacing the fourth fixing block 9, the fifth fixing block 10, etc.
[0039] By setting the first fixing groove 11, the second fixing groove 12, etc., when the fourth fixing block 9 and the fifth fixing block 10 need to be replaced, the fourth fixing block 9 and the fifth fixing block 10 can be directly taken out upward for replacement, and the operation is simple and convenient.
[0040] It should be noted that the various embodiments in this specification are described in a progressive manner. The key point of each embodiment is the difference from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0041] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention based on the above disclosure are within the scope of protection of the claims.
