Abstract

The invention discloses a fine adjustment type precision boring cutter, and relates to the technical field of boring cutters. The fine adjustment type precision boring cutter comprises a cutter handle, a dovetail guide rail structure, a boring cutter rod, a screw rod mechanism and a worm and gear structure. The dovetail guide rail structure is arranged at one end of the cutter handle; the boring cutter rod is arranged at one side of the dovetail guide rail structure; the screw rod mechanism is arranged in the dovetail guide rail structure; the worm and gear structure is in meshed transmission connection with the lead screw mechanism; and the worm and gear structure drives the lead screw mechanism to act in a transmission manner, then the dovetail guide rail structure is driven to move, and the position of the boring cutter rod is adjusted. According to the boring cutter, the problem that the production efficiency is reduced due to the increase of the stock quantity of cutters and the cutter replacement time since boring cutters need to be replaced for many times during boring is solved.

Description

technical field

[0001] The invention relates to the technical field of boring cutters, in particular to a fine-tuning precision boring cutter. Background technique

[0002] Boring machine refers to equipment for further processing of forged, cast or drilled holes. Boring can enlarge the aperture, improve precision, reduce surface roughness, and can better correct the deviation of the original hole axis. Boring can be divided into rough boring, semi-fine boring and fine boring. The dimensional accuracy of fine boring can reach IT8~IT7, and the surface roughness Ra value is 1.6~0.8um. A boring tool is a tool used in conjunction with a boring machine.

[0003] However, when boring, it is necessary to replace the boring tool several times to complete the boring process, thereby increasing the number of tool stocks and tool changing time, thereby reducing production efficiency. For the above-mentioned problems, no effective solution has been proposed yet. Contents of th...

Examples

Embodiment Construction

[0022] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.

[0023] Such as Figure 1-4 As shown, the present application relates to a fine-tuning precision boring tool. The fine-tuning precision boring tool includes: a handle 1; a dovetail guide rail structure 2, which is arranged at one end of the handle 1; a boring bar 3, which is arranged on one side of the dovetail guide rail structure 2; a screw mechanism 4, which is arranged on the The dovetail guide rail structure 2; and the worm gear structure 5, which is meshed and connected with the screw mechanism 4; the screw mechanism 4 is driven by the worm gear structure...
