Description

Technical Field

[0001] The utility model relates to the technical field of boring tools, in particular to an adjustable boring tool. Background Art

[0002] A boring tool is a kind of boring cutting tool. A single or multiple cutter blocks extending outside the tool shank are arranged on the tool shank. The boring operation is carried out by extending the boring tool into the hole of the workpiece to be machined. In the field of machining, with the continuous progress of industrial manufacturing technology and the increasing market demand, the requirements for machining accuracy, surface quality, machining flexibility and production efficiency are also getting higher and higher. When dealing with these high standards, the limitations of traditional boring tool devices are gradually revealed. There are often inaccurate problems in tool positioning and adjustment of traditional boring tool devices, which are difficult to meet the requirements of high-precision machining. Traditional boring tool devices usually can only machine workpieces with specific sizes and shapes, and it is difficult to quickly adapt to the machining requirements of different workpieces. This not only increases the production preparation time, but also reduces the overall efficiency of the production line. During the machining process, traditional boring tool devices are prone to increase the surface roughness due to tool position deviation and cutting vibration, and it is difficult to meet these high-quality standards. Therefore, we propose an adjustable boring tool. Content of the Utility Model

Through the transmission of the driving gear (5) and the linkage gear (6), the rotational force is converted into an axial force on the lead screw (7). The combination of the lead screw (7) and the slider (8) is equivalent to the resistance point and the fulcrum of the lever. By precisely controlling the rotation angle of the lead screw and the moving distance of the slider, fine adjustment of the tool position is achieved.

[0025] Furthermore, the lower end of the lead screw 7 is provided in a conical shape, and the inner end of the corresponding slider 8 corresponds to the lead screw 7, reducing the collision generated when the lead screw 7 enters and exits between the two sliders 8.

The extension column 14 connects the slider (8) and the slide groove (15) to ensure the stability and accuracy of the slider during movement. The limit block (16) is arranged at the inner end of the slide groove (15) and is fixedly connected to the inner wall of the boring tool body (1) to limit the stroke of the slider (8) and prevent it from leaving the predetermined position.

[0027] Furthermore, a semicircular sleeve 11 is installed at the lower end of the boring tool body 1, and a transverse groove is set at the position of the semicircular sleeve 11 corresponding to the position of the tool 4. The semicircular sleeve 11 is installed at the lower end of the boring tool body (1) and a transverse groove is set at the position of the tool (4) for further fixing or guiding the tool.

[0028] Furthermore, a fixed shaft is set in the upper half of the semicircular sleeve 11, and one end of the fixed shaft passes through the tool 4 and is fixedly connected to the other semicircular sleeve 11.

[0029] Furthermore, a plurality of through holes 12 are arranged on the surface of the semicircular sleeve 11, and fixing bolts 13 are installed inside the through holes 12, and the fixing bolts 13 are connected to the two semicircular sleeves 11, and the fixing bolts 13 fix the tool 4 so that the tool 4 and the two semicircular sleeves 11 are fixed together.

[0030] Furthermore, the lever assembly comprises a fine-tuning knob 3, a driving gear 5, a linkage gear 6, a screw rod 7, a slider 8, a spring 9 and a fixed block 10. One end of the fine-tuning knob 3 penetrates the surface of the boring tool body 1 and is connected to the driving gear 5. The side end of the driving gear 5 is meshed with the linkage gear 6, and the center of the linkage gear 6 is meshed with the screw rod 7. Slide blocks 8 are arranged at both ends of the lower half of the screw rod 7. The outer end of the slider 8 is fixedly connected to the spring 9, and the other end of the spring 9 is fixedly connected to the fixed block 10. The fixed block 10 is fixedly connected to the inner wall of the boring tool body 1, and the lower end of the slider 8 is movably connected to the fine-tuning knob 3. The fine-tuning knob (3) serves as the force point of the lever. Through the transmission of the driving gear (5) and the linkage gear (6), the rotational force is converted into the axial force on the screw rod (7). By accurately controlling the rotation angle of the screw rod and the moving distance of the slider, the fine adjustment of the tool position is achieved.

[0031] Working principle: The cutting tool (4) is installed at the lower end of the boring tool body (1) and is initially fixed by structures such as a semi-circular sleeve (11) and a fixed shaft. The fine-tuning knob (3) penetrates the surface of the boring tool body (1) and is connected to the internal drive gear (5). The linkage gear (6) meshes with the drive gear (5), and the lead screw (7) meshes with the center of the linkage gear (6). The slider (8) is installed at both ends of the lead screw (7) and is supported and limited by a spring (9) and a fixed block (10). When the position of the cutting tool needs to be adjusted, the operator rotates the fine-tuning knob (3). The rotating fine-tuning knob drives the drive gear (5) to rotate, and then transmits the rotational motion to the lead screw (7) through the linkage gear (6). The rotation of the lead screw (7) causes the slider (8) to move towards both ends. Since the lead screw has helical threads, the movement of the slider on the lead screw is precise, enabling fine position adjustment. The movement of the slider (8) is guided by the extension column (14) and the chute (15) to maintain smoothness and accuracy. At the same time, the spring (9) exerts a certain force on the slider to ensure its stability and reset ability during movement. The movement of the slider (8) is finally transmitted to the cutting tool (4) to achieve fine adjustment of the cutting tool position. Since this adjustment is minute, the machining accuracy can be significantly improved.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
