DETAILED DESCRIPTION

[0027] 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.

[0028] like Figures 1 to 5 As shown, this embodiment provides a front fork clamp brake block calibration device, including:

[0029] A base 11, the base 11 comprises a bottom plate 12, a support arm 13 and a top plate 14, and the top plate 14 is fixed on the bottom plate 12 through the support arm 13;

[0030] A positioning portion 15, the positioning portion 15 is mounted on the bottom plate 12, and a mounting hole 26 for mounting the clamp gate 16 is provided on the positioning portion 15;

[0031] A vertical clamping mechanism 17, the top of which is mounted on the top plate 14, and the lower end of which is used to clamp the clamp gate 16;

[0032] The extrusion block 18 is slidably disposed on the bottom plate 12 , and is used to position the brake portion 19 of the caliper brake 16 .

[0033] The technical effect of this solution is that the caliper brake 16 can be positioned, which makes it easier for workers to adjust the brake part 19 of the caliper brake 16, thereby improving the accuracy of brake adjustment and effectively improving work efficiency.

[0034] Among them, the through-shaft 27 of the caliper gate 16 itself is inserted into the mounting hole 26 of the positioning part 15, and then the vertical clamping mechanism 17 clamps the caliper gate 16. The caliper gate 16 is positioned by moving the extrusion block 18, which can avoid the movement of the caliper gate 16 and the brake part 19 is effectively positioned. Among them, the brake part 19 is also called a clamp block. The staff adjusts the brake part 19 by adjusting the mounting bolts on the brake part 19.

[0035] Furthermore, the vertical pressing mechanism 17 is a cylinder or a hydraulic cylinder.

[0036] As an implementation of this embodiment, the positioning portion 15 is cylindrical. The positioning portion 15 is detachably mounted in the mounting opening of the bottom plate 12. By replacing the positioning portion 15, it is possible to adapt to the adjustment of different types and batches of clamp gates 16. The diameters of the through-shaft 27 of clamp gates 16 of different specifications are also different, so positioning portions 15 of different specifications are required. And the positioning portion 15 can determine whether there is a batch error in the clamp gate 16 by combining it with the clamp gate 16.

[0037] As an implementation of this embodiment, the two ends of the extrusion block 18 are provided with bayonet 20, which is used to fit with the brake part 19. This solution can effectively tighten the extrusion block 18, can effectively prevent the extrusion block 18 from moving, and can make the positions of the two brake parts 19 more accurate.

[0038] As an implementation of this embodiment, a track 21 is provided on the bottom plate 12, and a slider at the lower end of the extrusion block 18 is arranged in the track 21. The track 21 is a strip-shaped opening. The slider includes a connecting arm 23 and a protrusion 22, and the two ends of the connecting arm 23 are respectively provided with protrusions 22. The protrusions 22 are in contact with the inner wall of the strip-shaped opening.

[0039] As an implementation of this embodiment, the protrusion 22 is cylindrical, and the diameter of the protrusion 22 is greater than the width of the connecting arm 23. The protrusion 22 is in sliding contact with the strip opening, while the connecting arm 23 is in a non-contact state with the strip opening, which can effectively improve the sliding accuracy and make the motion trajectory of the slider more accurate.

[0040] As an implementation method of this embodiment, Figure 5 As shown, a locking mechanism is also included, which includes a screw 24 and a support plate 25. The screw 24 is fixed to the base plate 12 through the support plate 25, and the axial direction of the screw 24 is perpendicular to the movement direction of the extrusion block 18. The screw 24 is used to tighten the extrusion block 18.

[0041] After the position of the extrusion block 18 is adjusted, the extrusion block 18 is tightened by tightening the screw 24, so that the staff can adjust the brake part 19. When the locking mechanism is not provided, the staff supports the extrusion block 18 with one hand and adjusts the brake part 19 with the other hand.

[0042] 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.
