Boring head

Abstract

The invention discloses a boring head and relates to the technical field of surface machining tools. The boring head comprises a spindle; a knife box frame is fixedly arranged at the front end of the spindle; a thrust ball bearing is arranged at the rear end of the spindle through a bearing sleeve; a rolling assembly is arranged on the outer edge of the spindle in a sleeving mode and located between the knife box frame and the thrust ball bearing; the knife box frame is internally provided with multiple knife boxes evenly distributed in the circumference; knife edges are arranged inside the knife boxes; boring cutters are arranged inside the knife edges; cutter heads of the boring cutters are located outside the knife boxes; knife box frame clamping bolts are arranged on a left end cover of the knife box frame, make contact with the knife boxes and clamp the knife boxes; lateral face puller bolts extending into the knife edges are arranged on the lateral installation faces of the knife boxes; bottom puller bolts extending into the knife edges are arranged on the bottom installation faces of the knife boxes; the lateral face puller bolts and the bottom puller bolts all play a role in fixing the boring cutters. The boring head is simple in structure and light in weight, interchangeability of tools is good, the machining precision can be improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of surface processing tools. Background technique [0002] When machining the inner surface of large-diameter cylinder workpieces, boring tools are often needed. The existing boring tools have complex structures, heavy weight, and poor interchangeability between tools, which not only affects the machining accuracy , It also increases the number of boring tools required in a complete process, and the production cost is higher. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a boring head with simple structure, light weight, good interchangeability between tools, improving machining accuracy and reducing production cost in view of the above-mentioned deficiencies in the prior art. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A boring head, includi...
