DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0026] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0027] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0028] refer to Figure 1-Figure 3 The illustrated embodiment of a high-stability sleeve boring tool comprises: a tool body 1, a tool clamp 2 and a locking screw 3. The tool body 1 is circumferentially provided with a plurality of mounting portions 11, and a mounting groove 12 adapted to the tool clamp 2 is provided on the inner side of the mounting portion 11. The mounting portion 11 is provided with a boss 13 at the mounting groove 12, and a screw hole 14 extending into the mounting portion 11 is provided at the boss 13; a groove 21 is provided on the tool clamp 2, and a mounting hole 22 is provided on the tool clamp 2 from the groove 21. The locking screw 3 passes through the mounting hole 22 and is threadedly connected to the mounting portion 11 through the screw hole 14. In this way, by providing the boss 13 at the mounting groove 12 and providing the groove 21 on the tool clamp 2, during installation, the groove 21 of the tool clamp 2 is clamped at the boss 13, and the locking screw 21 is fixed at the boss 13. The boss 13 thickens a part of the mounting portion 11, increases the number of locking teeth of the locking screw 21, makes the locking force stronger, and improves the stability of the tool during machining.

[0029] refer to Figure 3 As shown, a blade slot 23 is provided at one end of the tool clamp 2 away from the mounting portion 11, and a blade 4 is provided at the blade slot 23. The blade 4 is fixed at the blade slot 23 by bolts. In this way, the blade 4 can be conveniently installed at the blade slot 23 by bolts, and the blade 4 is also convenient for replacement. In the actual processing process, the side edge of the blade 4 conflicts with the slot wall of the blade slot 23.

[0030] refer to Figure 1-Figure 3 As shown, the end of the tool clamp 2 away from the blade groove 23 is threadedly connected with a screw rod 5, and the suspended end of the screw rod 5 abuts against the tool body 1. The diameter of the mounting hole 22 is larger than the diameter of the locking screw 3, and the opening of the groove 21 is larger than the boss 13. A plurality of adjustment holes 51 are provided on the suspended end ring side of the screw rod 5. In this way, during processing, the end of the tool clamp 2 away from the blade 4 abuts against the tool body 1 through the screw rod 5, so that the tool clamp 2 is supported from this direction. During installation, the screw rod 5 can be easily rotated through the adjustment hole 51 so that the suspended end of the screw rod 5 abuts against the tool body 1.

[0031] refer to Figure 1 and Figure 2As shown, a mounting interface 15 is provided at one end of the blade body 1 away from the mounting portion 11, a positioning groove 16 is provided on the mounting interface 15, and a through hole 17 penetrating the blade body 1 is provided on the inner side of the mounting interface 15. In order to facilitate the installation of the blade body 1, the mounting interface 15 and the through hole 17 are provided on the blade body 1, and the blade body 1 is limited by the positioning groove 16.

[0032] As a further optimization, in the present embodiment, two mounting parts 11 are provided, and adaptive adjustment can be performed according to actual production and demand.

[0033] The working principle of the utility model is as follows: a boss 13 is provided at the mounting groove 12, and a groove 21 is opened on the tool holder 2. During installation, the groove 21 of the tool holder 2 is clamped at the boss 13, and the locking screw 21 is fixed at the boss 13.
