Novel flange end face boring bevelling machine

Abstract

The invention discloses a novel flange end face boring bevelling machine. The novel flange end face boring bevelling machine comprises a machine body. The machine body is provided with a tool installing frame, an expansion mechanism and a tool feeding and retreating transmission device. The machine body comprises an upper machine base and an expansion base. The tool feeding and retreating transmission device is arranged on the upper machine base. The expansion mechanism is arranged on the expansion base. An installing support is fixedly arranged on the machine body. The tool installing frame is arranged on the installing support in a sliding manner. The upper machine base is rotationally arranged on the expansion base. The tool feeding and retreating transmission device comprises a speed changing drive gear and a tool feed screw. The speed changing drive gear drives the tool feed screw to rotate, and the tool feed screw is in threaded fit with the tool installing frame. The upper machine base is further provided with a rotation mechanism used for driving the upper machine base to rotate. According to the above scheme, it can be known that the rotation mechanism drives the upper machine base to rotate, the tool installing frame rotates along with the upper machine base, and when the upper machine base rotates, the tool feed screw can be driven to rotate, and feeding of the tool installing frame is achieved; and tool rotating and feeding are stable, and machining is convenient.

Description

technical field [0001] The invention relates to a beveling machine, in particular to a novel flange end face boring and beveling machine. Background technique [0002] The flange end face boring and beveling machine is used for the processing of the flange end face, which can cut thread lines, cut grooves or cut the end face on the flange end face. [0003] The Chinese patent number is 201420616607.8, which discloses a flange end face boring and beveling machine, including a driving member, a tensioning mechanism, a circular rotating disk, a tool mounting frame, and a drive mechanism for advancing and retreating the knife. The circular rotating disk includes a fixed disc, gear rotating disc and inner gear disc, the driving part is arranged on the fixed disc, the gear rotating disc is rotatably arranged on the fixed disc, the inner gear disc is fixedly arranged on the fixed disc, the gear on the output shaft of the driving part and the gear rotating disc meshing, the driving...

AI Technical Summary

Problems solved by technology

Problems in the above-mentioned technical solution: the tensioning mechanism of this type of splitting machine is in conflict with the outer wall of the flange, which takes up a large space and is not conducive to transportation; the mounting bracket is a bridge type bracket, which increases the cost; the gear rotating disc drives the installation The bracket rotates, and the setting of the gear rotating disc is too large, which is easily affected by the outside world, which is not conducive to the stable operation of the tool; the way of speed regulation is unreasonable, which is not conducive to the speed regulation of three or more gears
