[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] Please refer to Figure 1-Figure 3 The utility model discloses a hole positioning tool for a fork, wherein the fork 100 includes a horizontal section 110 and a vertical section 120 fixed to each other, the horizontal section 110 is provided with a support plate hole 111, and the vertical section 120 is provided with a sleeve hole 121. The hole positioning tool 200 includes:

[0030] A positioning rod has a first positioning portion at one end thereof which can be aligned with the support plate hole 111 , and a second positioning portion at the other end thereof which can be aligned with the shaft sleeve hole 121 ; a support column 216 is also provided in the middle of the positioning rod, and one end of the support column 216 can abut against the bottom plate of the horizontal section 110 .

[0031] Specifically, the hole positioning tool 200 in the present application includes a first positioning part, a second positioning part and a support column 216. By aligning the first positioning part with the support plate hole 111, and then making the support column 216 abut against the bottom plate of the horizontal section 110, the position of the second positioning part is unique, and the position aligned with the second positioning part is the position of the shaft sleeve hole 121 to be processed. Similarly, the second positioning part can also be aligned with the shaft sleeve hole 121, and then making the support column 216 abut against the bottom plate of the horizontal section 110. At this time, the position of the first positioning part is unique, and the position aligned with the first positioning part is the position of the support plate hole 111 to be processed. In this way, the relative position of the processed shaft sleeve hole 121 and the support plate hole 111 can have a higher accuracy to meet the use requirements.

[0032] Furthermore, it also includes a first positioning column;

[0033] The first positioning portion is a positioning hole 215 formed on the positioning rod, and the first positioning column can be inserted into the positioning hole 215 and the support plate hole 111 at the same time.

[0034] Specifically, if the position of the sleeve hole 121 is determined based on the support plate hole 111, the first positioning column is simultaneously extended into the support plate hole 111 and the positioning hole 215 so that the first positioning portion is aligned with the support plate hole 111, and then the support column 216 is pressed against the bottom plate of the horizontal section 110. At this time, the position of the second positioning portion is precisely positioned, and the aligned position is the position of the sleeve hole 121 required for processing.

[0035] Furthermore, the outer diameter of the first positioning column, the inner diameter of the positioning hole 215 and the inner diameter of the support plate hole 111 are equal.

[0036] The outer diameter of the first positioning column, the inner diameter of the positioning hole 215 and the inner diameter of the support plate hole 111 are equal, so that the first positioning column will not shake in the positioning hole 215 and the support plate hole 111, thereby improving the accuracy of the relative position of the sleeve hole 121 and the support plate hole 111.

[0037] Furthermore, it also includes a second positioning column, which can be inserted into the shaft sleeve hole 121, and the outer diameter of the second positioning column is equal to the inner diameter of the shaft sleeve hole 121;

[0038] The second positioning portion is a positioning notch 221 formed on the positioning rod, and an inner wall of the positioning notch 221 can abut against a peripheral wall of the second positioning column.

[0039] Specifically, if the position of the sleeve hole 121 is determined based on the sleeve hole 121, the second positioning column is extended into the sleeve hole 121 to align the second positioning portion with the sleeve hole 121, and then the support column 216 is pressed against the bottom plate of the horizontal section 110. At this time, the position of the first positioning portion is precisely positioned, and the aligned position is the position of the support plate hole 111 required for processing.

[0040] Furthermore, the inner wall of the positioning notch 221 is configured in an arc shape, and the inner wall of the positioning notch 221 can fit with the peripheral wall of the second positioning column.

[0041] Furthermore, the inner wall of the positioning notch 221 is semicircular.

[0042] The inner wall of the positioning notch 221 is arranged to be in an arc shape and can fit with the second positioning column, thereby increasing the contact area between the positioning notch 221 and the second positioning column and improving the positioning accuracy of the entire tooling.

[0043] Furthermore, the positioning rod includes a first support rod 210 and a second support rod 220 that are vertically fixed, the first support rod 210 is parallel to the horizontal section 110, the second support rod 220 is parallel to the vertical section 120, the first positioning portion is located at an end of the first support rod 210 away from the second support rod 220, and the second positioning portion is located at an end of the second support rod 220 away from the first support rod 210.

[0044] Furthermore, the first support rod 210 includes a first sliding section 211 and a second sliding section 212 that are slidably connected, one end of the first sliding section 211 is connected to the second support rod 220 , and the first positioning portion is disposed on the second sliding section 212 .

[0045] Specifically, the first support rod 210 is divided into a first sliding section 211 and a second sliding section 212 that are slidably connected. Through the relative sliding of the first sliding section 211 and the second sliding section 212, the distance between the first positioning portion and the second positioning portion in the horizontal direction can be adjusted, thereby enabling the tooling to perform hole positioning for forks 100 of different lengths.

[0046] Furthermore, a sliding space is provided in the first sliding section 211 to allow the second sliding section 212 to extend therein;

[0047] A plurality of first adjustment holes are formed on the first sliding section 211, and a plurality of second adjustment holes are formed on the second sliding section 212;

[0048] It also includes a plurality of adjustment posts 213 , and the adjustment posts 213 can be inserted into the first adjustment hole and the second adjustment hole at the same time.

[0049] Specifically, when adjusting the length of the first support rod 210, the second sliding section 212 can slide to different positions, so that the second adjustment hole on the second sliding section 212 is aligned with the different first adjustment holes on the first sliding section 211. After the first adjustment hole is aligned with the second adjustment hole, the adjustment column 213 is simultaneously extended into the second adjustment hole and the first adjustment hole in sequence to achieve the positioning of the first sliding section 211 and the second sliding section 212, so as to improve the accuracy of hole positioning.

[0050] Furthermore, locking screws 214 are provided on both sides of the first sliding section 211 . The locking screws 214 are threadedly connected to the first sliding section 211 . One end of the locking screw 214 can extend into the sliding space and abut against the second sliding section 212 .

[0051] Specifically, after adjusting the length of the first support rod 210, the locking screws 214 on both sides of the first sliding section 211 are rotated to make the locking screws 214 abut against the second sliding section 212, thereby locking the second sliding section 212 to prevent the adjustment column 213 from loosening and causing inaccurate positioning.
