[0018] See Figures 1 to 6 According to an embodiment of the present invention, a positioning device is provided, comprising: a positioning disk 1, the inner peripheral side of which has an inner conical surface 11; a machining hole 12 provided on the positioning disk 1; a locking sleeve 2, the locking sleeve 2 having an outer conical surface 21 that cooperates with the inner conical surface 11 of the positioning disk 1; a locking hole 22 provided on the inner peripheral side of the locking sleeve 2; the locking sleeve 2 being movably disposed along the inner conical surface 11 of the positioning disk 1 to adjust the inner diameter of the locking hole 22; at least one aperture conversion sleeve 3; at least one aperture conversion sleeve 3 being detachably disposed on the machining hole 12 for adapting to drill bits of different diameters; and a locking structure 4 for fixing the locking sleeve 2 to the positioning disk 1.

[0019] With the above-mentioned configuration, through the conical surface mating structure and the adjustable locking sleeve 2, this utility model can quickly adapt to shafts of different diameters, achieve precise positioning, improve drilling accuracy and efficiency, and solve the technical problem of inconvenient drilling processing.

[0020] Specifically, such as Figure 1 and Figure 2As shown, this utility model provides an end-hole positioning device, including a positioning disk 1, a mounting and fixing locking sleeve 2, a hole diameter conversion sleeve 3, and a locking bolt. The positioning disk 1 has an inner conical surface 11 on its inner circumference and multiple equally distributed machining holes 12 on its end face. Figure 2 The mounting and locking sleeve 2 has an outer conical surface 21 that mates with the inner conical surface 11, and its fixed position on the shaft can be adjusted by the locking bolt. The bore diameter conversion sleeve 3 can be inserted into the machining hole 12 to accommodate drill bits of different diameters.

[0021] In the positioning device of this embodiment, there are multiple machining holes 12; the multiple machining holes 12 are arranged around each other.

[0022] Specifically, such as Figure 2 As shown, there are multiple machining holes 12, which are arranged around the end face of the positioning disk 1. In this way, the arrangement of multiple machining holes 12 allows the device to perform multi-hole machining simultaneously or sequentially, improving machining efficiency, and is especially suitable for machining holes with pitch circle distribution.

In this way, the multi-hole circular arrangement makes the locking force distribution more uniform, improving the stability and load-bearing capacity of the overall structure.

[0032] In the positioning device of this embodiment, the bore diameter conversion sleeve (3) is a replaceable structure with various inner diameter specifications, which are adapted to different specifications of threaded bottom holes, such as M8, M10, M12, M14, and M16 threaded bottom holes. In this way, the replaceable bore diameter conversion sleeve 3 makes the device suitable for processing requirements of different bore diameters, improving the versatility and economy of the device.
