[0024] The utility model provides a part processing positioning tool, comprising:

[0025] A base 1 and a positioning member 2, wherein the base 1 is provided with an assembly hole and includes a first end surface 1a and a first side surface 1b;

[0026] The positioning member 2 includes a positioning platform 21, and a connecting rod is provided on a side of the positioning platform 21 close to the first side surface 1b, and the connecting rod passes through the assembly hole and is connected to the first nut 22;

[0027] A positioning column 23 is provided on one side of the positioning platform 21 away from the first side surface 1b, a screw rod 24 is provided on one end of the positioning column 23 away from the positioning platform 21, and a second nut 25 is provided on one end of the screw rod 24 away from the connecting rod;

[0028] The positioning platform 21 is further provided with a first positioning pin 26 and a second positioning pin 27 on a side away from the first side surface 1b.

[0029] The positioning column 23, the screw rod 24, the first positioning pin 26, and the second positioning pin 27 extend along the axial direction A;

[0030] The intersection of the central axis of the first positioning pin 26 and the first side surface 1b is the first intersection, the intersection of the central axis of the second positioning pin 27 and the first side surface 1b is the second intersection, the line between the first intersection and the second intersection is the first line, the first line is parallel to the first end surface 1a of the base 1, and the midline of the first line intersects with the central axis of the positioning column 23.

[0031] In a specific embodiment, Figure 2 As shown, the right side of the positioning platform 21 is close to the first side surface 1b of the base 1 and is fixed to the base 1 through the connecting rod and the first nut 22. The left side of the positioning platform 21 is provided with the positioning column 23, the first positioning pin 26 and the second positioning pin 27. The part 5 is installed from the left side. The through hole 5a is sleeved with the screw 24 and the positioning column 23, and the small hole 5b is sleeved with the first positioning pin 26 and the second positioning pin 27. The structure is simple and can maintain stability to prevent the part from rotating in the circumferential direction. Since the first connecting line is parallel to the first end face 1a, and the mid-perpendicular line of the first connecting line intersects with the central axis of the positioning column 23, the structure is conducive to quickly locating the position where the threaded hole 5c needs to be processed, that is, it can be processed vertically toward the first end face 1a. The structure is simple and stable, and it is convenient to quickly and accurately locate the threaded hole 5c to be processed.

[0032] During processing, the through hole 5a of the part 5 is sleeved on the positioning column 23, the part 5 is rotated, and any two adjacent small holes 5b on the part 5 are respectively sleeved on the first positioning pin 26 and the second positioning pin 27, and then the second nut 25 is sleeved on the screw rod 24, and the second nut 25 is rotated to fix the position of the part 5, thereby preventing the part 5 from moving axially. At this time, the required threaded hole 5c can be processed perpendicular to the first end face 1a.

[0033] Furthermore, the base 1 is L-shaped, including a vertical plate 11 and a horizontal plate 12, the positioning member 2 is arranged on the vertical plate 11, the horizontal plate 12 is arranged on the side of the vertical plate 11 away from the first side surface 1b, and the horizontal plate 12 is arranged at the end of the vertical plate 11 away from the first end surface 1a, such as Figure 3 As shown, this structure can improve the stability of the base 1, and further improve the stability of the part processing and positioning tooling.

[0034] Furthermore, a relief hole 23a is provided at the connection between the positioning column 23 and the screw rod 24. Figure 2As shown, during processing, the processing tool processes the threaded hole 5c vertically downward from the top of the base 1 on the circumference of the part 5, and the avoidance hole 23a is used to avoid the processing tool to avoid damage to the screw rod 24 and the connecting rod, thereby protecting the part processing positioning tooling.

[0035] Furthermore, it also includes a first gasket 3, which is sleeved on the connecting rod and arranged between the base 1 and the first nut 22. Figure 2 As shown, during installation, the connecting rod is passed through the assembly hole of the base 1, the first gasket 3 is first sleeved on the connecting rod, and then the first nut 22 is sleeved on the connecting rod and tightened so that the first gasket 3 is tightly against the base 1. The first gasket 3 increases the stability of the connection between the connecting rod, the first nut 22 and the base 1.

[0036] Furthermore, it also includes a second gasket 4, which is sleeved on the screw rod 24 and arranged between the positioning platform 21 and the second nut 25.
