The holder 11 has a sleeve extending in a straight direction, and the drill assembly 12 is connected to the bottom of the sleeve, so that the drill assembly 12 can rotate synchronously with the holder 11 and achieve the effect of drilling the product 3.

The sleeve boring cutter assembly 13 is connected with the tool apron 11, the sleeve boring cutter assembly 13 comprises a sleeve member 131 and a boring cutter unit 132 mounted on the sleeve member 131, the boring cutter unit 132 is provided with a plurality of symmetrically arranged blades 1322, and one end part of each blade 1322 adjacent to the blade 1322 is arranged outside the sleeve member 131, so that the sleeve boring cutter assembly 13 can enable the blades 1322 to process the outer diameter of the product 3 during the rotation process. The thickness of the blade 1322 is provided with a compensation through hole 4, so that the compensation through hole 4 of the blade 1322 can play a role in buffering and compensating in the subsequent moving process of the blade 1322 by the wedge-shaped block 1322, and the blade 1322 is prevented from cracking and being damaged. The end of each of the blades 1322 that is far away from the blade 1322 is provided with a wedge 1322 that abuts against the wedge 1322, the wedge 1322 is locked to the sleeve 131 by an adjusting screw 1323, and the thickness of the wedge 1322 gradually increases from a portion adjacent to the blade 1322 to a portion far away from the blade 1322.

In this embodiment, the tool holder 11 itself can rotate around a straight line in the extending direction of the tool holder under the action of the machine spindle, so that the drill assembly 12 and the sleeve boring tool assembly 13 can rotate along with the tool holder 11, and further the drill assembly 12 and the sleeve boring tool assembly 13 can rotate simultaneously, and in the process of moving the tool body 1 to the product 3, the drill assembly 12 and the sleeve boring tool assembly 13 respectively contact with the product 3, and further in the process of moving the tool once, the effects of drilling the product 3 by the drill assembly 12 and processing the outer diameter of the product 3 by the sleeve boring tool assembly 13 can be simultaneously achieved.

When the requirement for the outer diameter of the product 3 is changed, the adjusting screw 1323 connected to the wedge block 1322 is rotated, so that the adjusting screw 1323 can drive the wedge block 1322 to move relative to the blade 1322 in the thickness direction of the blade 1322, and the abutting position of the wedge block 1322 and the blade 1322 is changed, thereby achieving the effect of changing the overall position of the blade 1322. The wedge block 1322 is driven to change the abutting position of the blade 1322 on the thickness of the blade 1322 by the rotation of the adjusting screw 1323, so that the position of one end of the blade 1322 away from the wedge block 1322 is changed, and in the process, the compensation through hole 4 plays a role in compensating the deformation of the blade 1322, so that the blade 1322 is prevented from being damaged.

In this embodiment, the product 3 is firstly placed on the clamp 2, so that the clamp 2 positions the product 3, and then the tool body 1 moves towards the direction of the product 3 in a rotating state, so as to achieve the effects of drilling the product 3 and machining the outer diameter of the product. The clamp 2 can keep the product 3 stable in the processing process, and the processing stability of the product 3 is improved.

Specifically, the number of the blades 1322 is two, that is, two the blades 1322 are correspondingly arranged, so that in the rotating process, the two blades 1322 can achieve circular coverage in the rotating range through rotation, and therefore, in the process of machining the outer diameter of the product 3, the blades 1322 can achieve the effect of machining the outer diameter of the product 3 only by moving the thickness of the product 3 in the linear direction, and the whole machining process is simple and efficient.

Specifically, the drill assembly 12 is attached to a central location of the sleeve. So that the cutter assembly 12 located at the center of the sleeve can have a better clearance effect with the blades 1322 located outside the sleeve.

Specifically, an ER collet is arranged in the sleeve, the ER collet is connected with the drill assembly 12, and the extending direction of the ER collet can be kept the same as that of the sleeve, so that the drill assembly 12 and the tool apron 11 can be kept on the same rotating shaft during rotation, and further the fixing and drilling effects of the drill assembly 12 are better.

Specifically, one end of the blade 1322 adjacent to the wedge block 1322 has a chamfer that mates with the wedge block 1322. Therefore, the wedge-shaped block 1322 can be always abutted against the inclined surfaces in the process of rotating along with the adjusting screw 1323, and can be abutted against different positions of the inclined surfaces in the process, so that the stressed position between the wedge-shaped block 1322 and the blade 1322 is always kept stable, the situation that the blade 1322 is damaged due to the change of the contact position is avoided, and the service life of the boring cutter set assembly 13 is prolonged.
