Technical Field
[0001] The present application relates to the field of boring tools, and in particular to a boring tool. Background Art
[0002] A boring tool is a cutting tool used to machine holes inside a workpiece. Boring tools are often used to enlarge or finish existing holes to ensure that the size, shape and surface quality of the hole meet specific requirements. Unlike drills, boring tools are able to cut inside the hole and adjust the diameter of the hole while providing higher processing accuracy.

The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0033] like Figures 1 to 4As shown, a boring tool comprises a tool body 1, a tool seat 2, a tool handle 3 and an adjusting device 4, wherein the adjusting device 4 is arranged in the tool seat 2, the upper end of the tool body 1 is mounted on the adjusting device 4, the tool handle 3 is arranged at the upper end of the tool seat 2, the adjusting device 4 can drive the tool body 1 to move in a radial direction, the tool seat 2 is provided with a first mounting groove 21 in the radial direction, the first mounting groove 21 has an opening 24, the bottom of the tool seat 2 is provided with an adjusting groove 22, the adjusting groove 22 is connected with the first mounting groove 21, the adjusting device 4 comprises an adjusting block 41, an adjusting bolt 42, a limiting rod 43 and a limiting gasket 44, the adjusting block 41 can slide The cutter body 1 is movably installed in the first mounting groove 21, a cover plate 23 is provided at the opening 24, a limit gasket 44 is provided between the adjusting block 41 and the cover plate 23, an adjusting bolt 42 passes through the cover plate 23 and the limit gasket 44 in radial order and is threadedly connected with the adjusting block 41, a limit rod 43 passes through the limit gasket 44 and the adjusting bolt 42 in axial direction, the upper end of the cutter body 1 passes through the adjusting groove 22 and is connected with the adjusting block 41, the adjusting bolt 42 performs a rotational motion to adjust the adjusting block 41 in the first mounting groove 21 to drive the cutter body 1 to move in the radial direction, and the limit rod 43 is used to limit the distance that the cutter body 1 moves in the radial direction.
[0034] The present application adopts a combination structure of an adjustment block 41, an adjustment bolt 42, a limit rod 43 and a limit gasket 44, and this arrangement is expected to provide more accurate position adjustment of the cutter body 1. By rotating the adjustment bolt 42, a slight adjustment of the cutter body 1 in the radial direction can be achieved, thereby improving the processing accuracy.
[0035] In addition, the use of the limit rod 43 of the present application helps to limit the movement range of the cutter body 1 in the radial direction, which helps to ensure that the cutter body 1 does not exceed a predetermined range during the processing, thereby improving the controllability of the processing.
[0036] Moreover, the rotational movement of the adjustment bolt 42 of the present application can be achieved by manual rotation by the operator, which is relatively intuitive and convenient and can flexibly perform minor adjustments.
[0037] The modular arrangement of the adjustment block 41, the adjustment bolt 42, the limit rod 43 and other components of the present application facilitates maintenance and replacement. If maintenance or a change in the adjustment method is required, these modules can be replaced or adjusted relatively easily.
[0038] Finally, a cover plate 23 is provided at the opening 24 of the first mounting groove 21 of the present application. This arrangement helps to prevent external materials such as chips from entering the tool holder 2, thereby improving the stability and life of the equipment.
[0039] like Figure 4As shown, in this embodiment, the adjustment block 41 has a first mounting hole 411, and the first mounting hole 411 is used to install the blade body 1. After the blade body 1 is installed in the first mounting hole 411, it can be fixed by laser welding. The first mounting hole 411 passes through the adjustment block 41 from top to bottom.
[0040] like Figure 4 As shown, in this embodiment, a threaded hole 412 connected to the adjusting bolt 42 is provided on one side of the adjusting block 41, so as to facilitate the cooperation with the adjusting bolt 42. The threaded hole 412 provides an effective connection method, making the connection between the adjusting block 41 and the adjusting bolt 42 more stable. The threaded structure can provide a larger connection area, thereby enhancing the firmness of the connection and reducing the risk of loose connection caused by vibration or load generated during operation.
[0041] like Figure 4 As shown, in this embodiment, the adjusting block 41 is rectangular, and the side of the adjusting block 41 is provided with a chamfer 413. The chamfered surface reduces the friction when contacting the workpiece, which may improve the cutting efficiency, reduce wear, and reduce the friction loss of the overall system.
[0042] like Figure 4 As shown, in this embodiment, the adjusting bolt 42 includes a head 421 and a screw portion 422, and the screw portion 422 is penetrated by a second mounting hole 423 in the up-down direction, and the aperture of the second mounting hole 423 will directly affect the adjustment distance of the blade body 1. The aperture determines the range of motion of the limiting rod 43 in the second mounting hole 423, thereby determining the fine adjustment distance in the left-right direction that the adjusting bolt 42 can achieve.
[0043] like Figure 4 As shown, in this embodiment, the limiting gasket 44 is provided with a third mounting hole 441 for mounting the limiting rod 43 in the radial direction, and the rigidity of the entire system can be enhanced through the synergistic effect of the limiting gasket 44 and the limiting rod 43. In the case of high-speed cutting or large cutting depth, the improvement of rigidity helps to reduce vibration and improve the stability of processing.
[0044] like Figure 4 As shown, in this embodiment, the cover plate 23 is installed at the opening 24 by means of screws 233 , a countersunk hole 232 is provided on one side of the cover plate 23 , and a through hole 231 is provided in the countersunk hole 232 .
[0045] like Figure 4 As shown, in this embodiment, the adjustment slot 22 is in an oblong shape.
[0046] like Figure 4As shown, in this embodiment, the first mounting slot 21 is rectangular, and the oblong slot may provide a larger adjustment range. Due to the larger long axis direction, the adjustment block 41 can achieve a larger displacement in the slot, thereby increasing the fine adjustment range of the blade body 1 in the radial direction.
[0047] In this embodiment, a blade is disposed at the lower end of the cutter head.
