Drive structure of chip removal bar

Abstract

The invention discloses a driving structure of a scrap removal rod. The driving structure comprises a straight strip shaped scrap removal groove, the scrap removal rod, a driving rod, a supporting rod, a horizontal retaining bar, a guide bar, a limiting part and an oblique extension bar. The bottom end of the scrap removal rod is capable of extending into the bottom of the scrap removal groove; the driving rod which is positioned above the scrap removal groove is hinged to the top end of the scrap removal rod and used for driving the scrap removal rod to reciprocate along the length direction of the scrap removal groove; the supporting rod is fixed to the scrap removal rod; the horizontal retaining bar is used for supporting the supporting rod to move horizontally; the guide bar which is positioned at a first end of the retaining bar is hinged to the retaining bar and used for guiding the supporting rod to move towards the retaining bar; the limiting part is positioned below the guide bar and used for supporting the guide bar; the oblique extension bar which extends downwardly from a second end of the retaining bar is used for guiding the supporting rod to slide down gradually from the second end of the retaining bar. The driving structure of the scrap removal rod is reasonable in structure; the scrap removal rod in reverse movement can be lifted up, and consequently resistance of cutting liquid is reduced, the probability of returning of metal scraps is reduced, and scrap removal efficiency is improved; liquid in the scrap removal groove can be prevented from splashing in falling of the scrap removal rod.

Description

technical field [0001] The invention relates to a driving structure of a chip removal rod. Background technique [0002] The chip flute is used to collect the working fluid with chips discharged from the machine tool. One end of the flute is closed, and the other end is the chip discharge end. The chip flute is generally equipped with a chip removal rod, and the chip removal rod gradually pushes the metal chips in the chip flute to the chip discharge end by reciprocating movement, and finally discharges from the chip discharge end. The metal chips move from the closed end of the chip flute to the chip discharge end, forming the chip discharge direction. When the chip removal rod moves along the chip removal direction, the bottom end of the chip removal rod abuts against the bottom of the chip removal groove, which can drive metal chips along the chip removal direction. However, when the chip removal rod moves in the opposite direction (opposite to the chip removal directi...

AI Technical Summary

Problems solved by technology

However, when the chip removal rod moves in the opposite direction (opposite to the chip removal direction), if the bottom of the chip removal rod is still in contact with the bottom of the chip removal groove, metal chips may be brought back, which will reduce the efficiency of chip removal

And when the chip removal rod moves in the opposite direction (opposite to the chip removal direction), it will be resisted by the cutting fluid
