Problems solved by technology
Generally, the cutter head is installed in the hole of the boring bar and pressed with screws or bolts. The distance from the tip of the cutter head to the rotation center of the boring tool can only be realized by the position of each pressing tool, and the adjustment of the tool is troublesome and imprecise.
Especially when boring precise holes, the processing quality is greatly affected and the efficiency is low

Embodiment Construction
[0014] The boring tool is connected to the main shaft of the machine tool with the tapered shank at the back of the tool body (1), and the tool head (9) is installed in the hole at the front end of the telescopic tool bar (7) and pressed with a screw (8). Head (9) on telescoping knife bar
[0015] (7) The position in the hole gradually completes the rough boring and semi-fine boring of the hole.
[0016] Knife adjustment structure see attached figure 1 , telescopic cutter bar (7) is contained in the oblique hole of cutter body (1) and compresses with bolt (10). The fit between the telescopic knife rod (7) and the inclined hole of the cutter body (1) is a clearance fit, and H7 / g6 is optional, and the plane of the front end of the bolt (10) presses against the plane parallel to its axis of the telescopic knife rod (7) on, see attached figure 2 . Press it with bolt (10) when boring, and loosen it when adjusting the knife. Pin (6) is respectively contained in the hole perpen...

Description
technical field [0001] The invention relates to an adjusting device for a processing tool of a mechanical product part, especially a precise tool adjusting mechanism. Background technique [0002] The general method of processing holes with high precision requirements on mechanical parts is to complete them with a boring tool on a boring machine. People in the same industry know that the diameter of the boring hole is determined by the distance from the tip of the cutter head to the center of rotation of the boring tool. Generally, the cutter head is installed in the hole of the boring bar and pressed with screws or bolts. The distance from the tip of the cutter head to the center of rotation of the boring cutter can only be realized by the position of each pressing of the cutter, and the adjustment of the cutter is troublesome and imprecise. Especially when boring precise holes, the processing quality is greatly affected and the efficiency is low. Contents of the inventi...
