Precise rotating cutter head feeding direction changing transmission device

Abstract

The invention discloses a precise rotating cutter head feeding direction changing transmission device. The precise rotating cutter head feeding direction changing transmission device comprises a rotating cutter head body and a direction changing inclined guide rod; the upper plane of the rotating cutter head body is connected with the end face of a main shaft in a fastening mode, a radial slidingplate is installed on the lower portion of the rotating cutter head body, a rectangular through groove is formed in the portion, between the upper portion of the radial sliding plate and the end faceof the main shaft, of the middle of the rotating cutter head body, a driven block is arranged in the rectangular through groove, and a cylindrical inclined hole is formed in the driven block; a driving guide column is arranged in a central guide hole of the main shaft, the diameter of the driving guide column is smaller than that of the central guide hole of the main shaft, a circular-ring-shapedspace is reserved, and a main guide sleeve is arranged in the circular-ring-shaped space formed between the driving guide column and the main shaft; and the driving guide column is provided with a cylindrical inclined hole, one end of the direction changing inclined guide rod is installed in the cylindrical inclined hole, the other end of the direction changing inclined guide rod is installed in the cylindrical inclined hole of the driven block, then a circular-ring-shaped space is reserved, and a driven guide sleeve is arranged in the circular-ring-shaped space formed between the direction changing inclined guide rod and the driven block. According to the precise rotating cutter head feeding direction changing transmission device, the transmission direction is changed by adopting the rolling direction changing inclined guide rod, and then conversion and transmission of axial power to the radial rotating cutter head body are achieved.

Description

technical field [0001] The invention relates to a transmission technology for changing the feeding direction of a rotating disk, in particular to a feeding direction changing device for a rotary cutter head which adopts a rolling direction-changing inclined guide rod to change the driving direction. Background technique [0002] Various radial processing problems are often encountered in mechanical processing, especially the radial element processing of non-rotating parts, such as the end face of the hole on the box-type parts, the circumferential convex table surface, and the inner and outer grooves. The machine tool spindle is not only It needs to rotate with the tool at the front end, and at the same time drive the tool through the power parts such as the oil cylinder or motor at the rear end of the main shaft to realize the radial linear feed movement, so as to realize the cutting of machining allowance and the control of radial dimension; It is an essential and importan...

AI Technical Summary

Problems solved by technology

[0003] In view of the complex structure, large size, low transmission accuracy and low rigidity of various radial machining transmission direction changing devices often encountered in the above-mentioned mechanical processing, the present invention proposes a device that uses a rolling direction-changing inclined guide rod to change the transmission direction. The feed direction changing device of the rotary cutter head has a simple and compact structure and no backlash in the transmission, thus effectively improving the transmission accuracy and rigidity
