Technical Field

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

[0002] When processing parts, they are generally cut by tools. However, when processing deep cavities of parts, in order to facilitate processing, the tool head can generally be rotated. However, during the rotation process, the tool head is prone to shaking, which affects the accuracy of tool processing. For this reason, we propose an adjustable bevel processing tool. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide an adjustable bevel processing tool, which, through the mutual cooperation of the tool assembly and the rotation adjustment assembly, is suitable for the inclination of different angles in the deep cavity of the part when in use. The inclined surfaces of different angles in the deep cavity can be flexibly and adjustable for stable processing, and the tool can be prevented from shaking during the rotation adjustment process.

[0004] In order to solve the above technical problems, according to one aspect of the utility model, the utility model provides the following technical solution: an adjustable bevel processing tool, comprising:

[0005] A tool assembly, the tool assembly comprising a basic handle, a connecting block arranged below the basic handle, a rotating joint rotatably connected to the connecting block, and a rotating tool head connected to the rotating joint;

[0007] As a preferred solution of the adjustable bevel machining tool described in the utility model, a first threaded hole is formed on the bottom surface of the connecting block, and the first threaded bolt is connected to the first threaded hole;

[0008] The first threaded bolt can lock the connecting block in this way.

[0009] As a preferred solution of the adjustable bevel machining tool described in the utility model, the second rectangular notch and the second raised horizontal plate are engaged with each other, and the second rectangular notch limits the second raised horizontal plate;

[0010] This structural design prevents the rotating cutter head from shaking.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] 1. The utility model cooperates with the tool assembly and the rotation adjustment assembly to achieve the goal of being suitable for tilting at different angles in a deep cavity of a part during use. The inclined surfaces at different angles in the deep cavity can be flexibly and adjustable for stable processing, preventing the tool from shaking during the rotation adjustment process.

[0016] 2. Based on the first beneficial effect, the adjusted tool is limited for a second time by setting a limit locking component to avoid the problem of bolt loosening when the tool is used after the angle adjustment is completed, thereby affecting the stability of the tool.

[0017] During use, the user rotates the third threaded bolt in the opposite direction, and after loosening the third threaded bolt, the user turns the rotating joint, so that the rotating joint is rotated by the third threaded bolt after being screwed, thereby driving the rotating cutter head to rotate. In this way, when the rotating cutter head is adjusted to the required position, the user can rotate the third threaded bolt forward to lock it. In the process of connecting the rotating joint with the rotating cutter head, the second raised cross plate is fitted with the second rectangular groove, so that it can be limited and locked by the second threaded bolt. In the process of connecting the base handle with the connecting block, the first raised cross plate is fitted with the first rectangular groove, and locked by the first threaded bolt. The structural design of the progressive limiting and locking layer by layer can prevent the connecting block and the rotating joint from driving the rotating cutter head to shake during the adjustment process.

[0036] When the rotary cutter head 14 is locked by the second threaded bolt 28, the user pushes the slider 35 to move in the slide groove 34 until the slider 35 moves to the corresponding limit hole 32 position. At this time, the user rotates the threaded column 37 forward, and the threaded column 37 is threaded progressively in the second threaded hole 36 until the end of the threaded column 37 is stuck in the corresponding limit hole 32. At this time, the user continues to rotate the threaded column 37, and the threaded column 37 can tighten the slider 35, so that the rotary joint 13 can be limited for the second time, so as to avoid the problem of loosening and tilting of the rotary cutter head 14 during use after the rotary joint 13 is locked.
