DETAILED DESCRIPTION

[0029] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0030] like Figures 1 to 7 As shown, this embodiment provides a front fork V-brake caliper block calibration device, comprising:

[0031] A support plate 11, on which a holder 12 is disposed, and on which a notch 15 for mounting a vertical tube 14 of a front fork 13 is disposed;

[0032] A tightening mechanism, which is mounted on the support plate 11 and has a positioning rod 16, which is used to be inserted into a fork leg 17 of the front fork 13;

[0033] A clamping assembly, which is mounted on the support plate 11 and is used to clamp the vertical pipe 14;

[0034] The positioning block 18 is detachably mounted on the support plate 11 , and is used to position the brake portion 19 on the fork leg 17 .

[0035] The technical effect of this solution is that the brake part 19 of the V-brake on the front fork 13 can be accurately positioned, and the staff can adjust the brake part 19 by manually rotating the bolts on the brake part 19, which has the advantages of convenient adjustment and high adjustment accuracy.

[0036] The front fork 13 in this solution has a vertical tube 14 and two fork legs 17, each of which is provided with a V brake, wherein the brake part 19 of the V brake is also called a clamp block. During installation, the two fork legs 17 are clamped on the positioning rod 16, and the vertical tube 14 is clamped into the notch 15 of the clamping seat 12. At this time, the clamping assembly squeezes the end of the vertical tube 14, thereby achieving the positioning of the entire front fork 13, effectively avoiding the movement of the front fork 13. By adjusting the positioning block 18, the positioning block 18 is adjusted to a suitable position so as to effectively contact the brake part 19, and the staff adjusts the brake part 19 by rotating the bolts on the brake part 19.

[0037] Furthermore, a pad block 31 is provided at the lower end of the support plate 11, so that there is space at the lower end of the support plate 11, which is convenient for transporting the support plate 11.

[0038] As an implementation of this embodiment, the pressing assembly includes a first cylinder 20. The first cylinder 20 is fixed on the support plate 11 through a mounting seat, and a pushing column 32 is fixed on the piston rod of the first cylinder 20. The pushing column 32 can be made of rubber material or plastic material.

[0039] As an implementation mode of this embodiment, one end of the fork leg 17 away from the vertical tube 14 has a mounting opening 21 for mounting the front wheel, and the positioning rod 16 is inserted into the mounting opening 21 .

[0040] As an implementation manner of this embodiment, the pressing mechanism includes a fixing block 22 , a sleeve 23 is installed in the fixing block 22 , and the positioning rod 16 is inserted into the sleeve 23 .

[0041] In this solution, there is only one positioning rod 16. Through the assembly relationship between the positioning rod 16 and the mounting openings 21 of the two fork legs 17, the concentricity of the mounting openings 21 of the two fork legs 17 can be detected, thereby ensuring that the front fork 13 can be accurately installed on the tire.

[0042] As an implementation of this embodiment, the pressing mechanism also includes a second cylinder 24, which is arranged on the support plate 11 through a mounting seat, and a pressure column 25 is provided on the piston rod of the second cylinder 24, and the pressure column 25 is used to press the fork leg 17.

[0043] Furthermore, a guide opening 26 is provided on the pressure column 25, and the positioning rod 16 can be slidably inserted into the guide opening 26 of the pressure column 25. The technical effect of this solution is that the pressure column 25 can effectively contact and squeeze the fork leg 17, thereby improving the stability of the installation of the front fork 13.

[0044] As an implementation of this embodiment, the positioning block 18 is installed on the support plate 11 through a screw rod 27 .

[0045] As an implementation method of this embodiment, Figure 1 As shown, a plurality of through holes 28 for inserting screws 27 are arranged along a straight line on the support plate 11. In this scheme, the distance of adjusting the positioning block 18 each time is the distance between two adjacent through holes 28, and the adjustment distance is immutable. Or, as Figure 2 and 3 As shown, a strip-shaped opening 29 for passing a screw rod 27 is provided on the support plate 11. In this solution, the adjustment distance of the positioning block 18 is variable. After the position of the positioning block is adjusted, the screw rod 27 is tightened in the threaded hole at the lower end of the positioning block 18 to achieve the fastening of the positioning block 18.

[0046] As an implementation method of this embodiment, both sides of the positioning block 18 are provided with limiting protrusions 30 for positioning the brake part 19. This is convenient for better tightening the brake part 19 and facilitating accurate adjustment of the brake part 19.

[0047] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
