Automatic shaft ribbing tool

Abstract

The invention provides an automatic shaft ribbing tool. The automatic shaft ribbing tool comprises a machining platform, a lower die seat, an upper die seat, a lower ribbing die, an upper ribbing die, a driving mechanism, a mounting plate, a clamp, a gear, a mounting seat, a rack, a first air cylinder and a clamping air cylinder. The invention provides a mechanism capable of realizing automatic rotation of a shaft to be machined for a compression tool. When the automatic shaft ribbing tool is used, the upper die seat is pressed on the surface of the shaft to finish first time of ribbing; after the first time of ribbing is finished, the shaft to be machined is clamped by the clamping air cylinder, and the first air cylinder drives the rack to move from front to back, so that the gear is driven to rotate, and furthermore, the shaft to be machined in a clamp is driven to rotate; and after the shaft to be machined rotates for a pre-set angle, the driving mechanism drives the upper die seat to be pressed down so as to carry out second time of ribbing. With the adoption of the structure provided by the invention, the shaft to be machined does not need to be manually rotated, and can rotate for the pre-set angle completely through setting a distance, so that influences caused by artificial factors are avoided, and the machining precision of the shaft and the quality stability of a product are effectively improved; and meanwhile, compared with manual operation, the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of shaft processing equipment, in particular to an automatic beading tool for shafts. Background technique [0002] The shaft beading process is often processed by a press or a punching machine. Generally, manual operation is adopted, one person and one machine, the workpiece is placed in the beading mold, and the beading process is performed, and the material is manually operated up and down. For example, the Chinese invention patent application with the application publication number CN104128502A "A kind of armature shaft beading mold" (application number: CN201410349763.7), the Chinese utility model patent "shaft beading device" (application number: CN202137243U) with the authorized announcement number CN202137243U : CN201120200392.8) etc. all disclose the structure of beading device.

Problems solved by technology

[0003] Existing presses used for ribbing of shaft workpieces are mainly realized by upper dies and lower dies. The lower mold corresponding to the mold is set on the upper end of the lower mold base of the press, and the lower mold base is set on the working table of the press. The beading process is mainly realized through the corresponding cutting edges on the upper mold and the lower mold. Inside the cutting edge of the lower die, the upper die seat drives the upper die to press down, so that the workpiece is beaded between the upper die and the lower die. This beading process realized on the press machine generally adopts manual loading and unloading during loading. , this not only increases the labor intensity of the operator, but the production efficiency is low, and sometimes the workpiece cannot be placed in the position, resulting in a poor chopping distance; When it is necessary to press eight ribs on the surface of the shaft, it is necessary to manually rotate the shaft 45 degrees for the second pressing after the first pressing. Such a rotation angle is difficult to grasp and requires the operator to master it skillfully. However, even for skilled workers, there is a certain error between each rotation, which affects the machining accuracy of the shaft
