Technical Field

The invention relates to a chip removing device, in particular to an automatic chip removing device of a broach.

Background

When using fixed broach to carry out automated processing to big batch work piece, in order to guarantee automated processing's demand, need fix the broach on the bed body. The workpiece enters the area to be processed through the automatic feeding device, and the workpiece passes through the broach from top to bottom under the action of the oil cylinder push rod, so that the processing is finished, and the automatic broaching device is different from the traditional broaching principle. Because the chip groove of the broach is upward, processed scrap iron is difficult to remove in the chip groove, and the scrap iron accumulated in the chip groove of the broach can cause adverse effect on the normal work of the broach, thereby not only affecting the processing quality of workpieces, but also greatly shortening the service life of the broach. In order to remove the scraps, the traditional method is to manually take a steel wire brush to remove the scraps, so that the efficiency is low, the labor intensity is high, the danger coefficient is high, and the influence on the rhythm of automatic processing can be generated.

Disclosure of Invention

The invention aims to overcome the defects of the technology and provides the automatic broach scurf removing device which is reasonable in design, simple in structure and capable of removing scurf quickly and accurately.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides an automatic antidandruff device of broach, includes cylinder, cylinder fixing base, guide pillar, push rod, guide holder, brush head fixing base, guide pin bushing, support, brush head, its characterized in that: because of the broach is fixed, brush first one end is equipped with the profile of tooth corresponding with broach chip pocket, clears away the iron fillings in every chip pocket of broach through the tooth on the brush head, owing to draw big chip pocket and brush first profile of tooth to correspond, so the clearance is very clean, and the chip removal is effectual, and the iron fillings that brush head was cleared away can be sent fixed position under the control of cylinder stroke and be convenient for centralized processing.

Furthermore, the two ends of the brush head are respectively provided with a tooth shape corresponding to the broach chip pocket, so that after one end is worn, the other end can be quickly replaced for continuous use. One workpiece is used twice, and the benefit is improved.

The brush head is arranged on the brush head fixing seat through a bolt, the brush head fixing seat is also provided with a guide pillar and a push rod, the push rod is connected with the air cylinder to complete the front-back motion, and the brush head fixing seat and the air cylinder are fixedly connected with the support into a whole through the air cylinder fixing seat and the guide seat.
