[0022] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited are not intended to limit the present utility model.

[0023] Referring to Figure 1 and 2 As shown, a double - tool for a machine tool according to the present utility model includes a tool holder 1, a cutting tool 2, and a chamfering tool 3. The tool holder 1 is provided with a first fixing seat 11 and a second fixing seat 12 oppositely. The cutting tool 2 is arranged in the first fixing seat 11 for machining the grooves and diameters of a product, and the chamfering tool 3 is arranged in the second fixing seat 12 for machining the chamfers of the product. An avoidance groove 13 is provided on the tool holder 1 between the first fixing seat 11 and the second fixing seat 12.

[0024] Further, the cutting tool 2 includes a first shank 21 and a first cutting edge 22. The first cutting edge 22 includes a groove machining convex edge 221, a diameter cutting edge 222, a first relief portion 223, and a second relief portion 224. The diameter cutting edge 222 is arranged between the groove machining convex edge 221 and the first relief portion 223, and the second relief portion 224 is arranged adjacent to the groove machining convex edge 221.

[0025] Further, the chamfering tool 3 includes a second shank 31 and a second cutting edge 32. The second cutting edge 32 includes a chamfering edge 321, a third relief portion 322, and a fourth relief portion 323. The third relief portion 322 is arranged between the chamfering edge 321 and the fourth relief portion 323.

[0026] Preferably, the first fixing seat 11 and the second fixing seat 12 are respectively provided with locking components for fixing the cutting tool 2 and the chamfering tool 3.

[0027] In this embodiment, the locking assembly includes a transverse locking bolt 14 and a longitudinal locking bolt 15, and the transverse locking bolt 14 and the longitudinal locking bolt 15 are arranged on the adjacent sides of the first fixed seat 11 and the second fixed seat 12. Specifically, the transverse locking bolts 14 are oppositely arranged on both sides in the horizontal direction of the first fixed seat 11 and the second fixed seat 12, and the transverse locking bolts 14 extend into the tool mounting holes in the first fixed seat 11 and the second fixed seat 12. By adjusting the depth of the transverse locking bolts 14 in the tool mounting holes, the transverse locking bolts 14 are brought into contact with the cutting tool 2 and the chamfering tool 3, thereby realizing the unilateral locking of the cutting tool 2 and the chamfering tool 3; the longitudinal locking bolts 15 extend into the tool mounting holes in the first fixed seat 11 and the second fixed seat 12 from the front side of the tool holder 1 and are respectively in contact with the cutting tool 2 and the chamfering tool 3, realizing the unilateral locking of the cutting tool 2 and the chamfering tool 3 from the front side of the tool holder 1. The combination of the transverse locking bolts 14 and the longitudinal locking bolts 15 makes the locking of the cutting tool 2 and the chamfering tool 3 more firm, not prone to loosening or displacement, and ensures the perpendicularity of the cutting tool 2 and the chamfering tool 3.

[0028] Wherein, the inner walls on both sides at the opening of the avoidance groove 13 are inclined towards the first fixed seat 11 and the second fixed seat 12. The inclined design of the opening of the avoidance groove 13 makes the opening of the avoidance groove 13 larger. When the product approaches the tool holder 1, it can avoid the contact between the product and the tool holder 1 and ensure the machining accuracy of the product.

[0029] In this embodiment, a positioning pin 16 is provided at the center position of the bottom of the tool holder 1. When the tool holder 1 is installed on the drilling machine, the positioning pin 16 is used to position the position of the tool holder 1 to ensure that the installation position of the tool holder 1 is accurate and in place.

[0030] Furthermore, an exhaust hole 131 is provided in the avoidance groove 13, and the exhaust hole 131 is communicated with the mounting hole on the tool holder 1 for mounting the positioning pin 16. The design of the exhaust hole 131 can facilitate the disassembly of the positioning pin 16. When the positioning pin 16 is damaged and needs to be replaced, the exhaust hole 131 can make the disassembly of the positioning pin 16 more labor-saving and prevent the situation where the positioning pin 16 cannot be pulled out.

[0031] In this embodiment, a first mounting and fixing portion 17 and a second mounting and fixing portion 18 are respectively provided on both sides of the tool holder 1. The first mounting and fixing portion 17 is arranged in a stepped manner with the first fixed seat 11, and the second mounting and fixing portion 18 is arranged in a stepped manner with the second fixed seat 12.

[0032] In addition, locking and fixing parts 19 are arranged on both sides of the first fixing seat 11 and the second fixing seat 12 on the tool holder 1, and mounting and fixing holes are provided on the locking and fixing parts 19. After both sides of the tool holder 1 are locked and fixed to the drilling machine through the first mounting and fixing part 17 and the second mounting and fixing part 18 respectively, the locking and fixing parts 19 further lock and fix both sides of the first fixing seat 11 and the second fixing seat 12 to ensure the tightness of the connection between the tool holder 1 and the drilling machine.

[0033] During specific processing, the tool holder 1 is locked and fixed to the drilling machine, and at the same time, the product is clamped to the fixture so that the product is aligned with the avoidance groove 13 on the tool holder 1. By controlling the drilling machine, the tool holder 1 drives the cutting tool 2 and the chamfering tool 3 to continuously approach the product during rotation, and at the same time, a certain gap is reserved between the avoidance groove 13 and the product to avoid contact. Since the rotating mechanism drives the product to rotate continuously, during the rotation of the product, the cutting tool 2 realizes the processing of the outer diameter and groove of the product, and while the chamfering tool 3 processes the outer diameter and groove of the product, it realizes the chamfering processing of the product. Compared with using a single tool, not only the processing efficiency is improved, the tool wear is small, and the service life is extended, but also the tool loss cost caused by using a single tool is greatly reduced, and the machine tool maintenance cost is reduced.

[0034] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
