[0027] In use, the guide sleeve 2 is installed on the workpiece 1, the alloy wear-resistant sleeve 4 is fixed on the tensioning installation device 3, the tensioning installation device 3 is inserted into the guide hole 201, and the guide key 302 abuts against the guide keyway 202 so that the alloy wear-resistant sleeve 4 can smoothly enter the inclined hole 101.

[0028] The guide sleeve 2 is customized according to the outer contour of the workpiece 1. The guide hole 201 on the guide sleeve 2 is aligned with the oblique hole 101 on the workpiece 1. The guide sleeve 2 is fixed on the workpiece 1 to play a positioning and guiding role. The alloy wear-resistant sleeve 4 is fixed at its end by an outwardly expanding tapered cylinder 305 and abuts against the outer sleeve 301 to achieve positioning. The tensioning installation device 3 is inserted into the guide keyway 202 by the guide key 302 to achieve positioning, thereby ensuring that the alloy wear-resistant sleeve 4 is correctly put into the oblique hole 101.

[0029] This system ensures that the alloy wear-resistant sleeve is installed accurately and securely in the designated position, while utilizing components such as guide sleeves and guide keys to achieve precise positioning and guidance. This is crucial for improving work efficiency and ensuring assembly quality.

[0030] Preferably, the guide sleeve 2 has positioning holes 203 on both sides and multiple locking holes 204 on the periphery of the tail of the guide sleeve 2;

[0031] The inner contour of the guide sleeve 2 matches the outer contour of the workpiece 1. The positioning hole 203 is provided with a threaded set screw. By adjusting the set screw against the outer wall of the workpiece 1, the guide hole 201 on the guide sleeve 2 is aligned with the inclined hole 101.
