A linear feeding and discharging mechanism of a bar material automatic chamfering machine

Abstract

The invention discloses a linear feeding and discharging mechanism of a full-automatic bar chamfering machine. The linear feeding and discharging mechanism of the full-automatic bar chamfering machine comprises a work head mechanism, a feeding mechanism and a receiving mechanism. The work head mechanism comprises a clamping head used for clamping bars and a spindle used for driving the clamping head to rotate. A hollow inner cavity is formed in the spindle, and the bars at the front end of the spindle can be conveyed out toward the rear end of the spindle along the hollow inner cavity. The feeding mechanism comprises a linear feeding precision linear module which can make linear reciprocating movement, and the linear feeding precision linear module is arranged at the position where linear reciprocating movement can be made in the axis direction of the spindle of the work head mechanism to enable the bars of the work head mechanism to be pushed in the hollow inner cavity of the spindle along a straight line. The receiving mechanism is arranged to enable the bars discharged by the hollow inner cavity of the work head mechanism to be conveyed to a receiving position in a linear mode. According to the linear feeding and discharging mechanism, the feeding mode is changed into a front positioning mode from a rear positioning mode, the feeding mode of front feeding and front discharging is changed into a work head inside linear discharging mode, so that the entire structure of the mechanism is compact, and the production efficiency and the product percent of pass are improved while the requirement for precision can be met.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a linear feeding and discharging mechanism of a bar material automatic chamfering machine. Background technique [0002] There are mainly two existing bar chamfering machines, one is a manual tool grinder, and the other is an automatic chamfering machine. [0003] The main structure of the manual tool grinder is a grinding wheel mechanism, a sliding platform and a chuck clamping mechanism. When working, the chuck clamping mechanism clamps the bar material to rotate, and is driven by the sliding platform to reciprocate through the rotating grinding wheel on the grinding wheel mechanism at a certain angle. Grinding processing. The manual tool grinder adopts the positioning after tooling and the manual three-grab chuck clamping method to clamp the bar. When operating, the operator must hold the bar with one hand and lock it. This method determines the poor positioning accura...

Problems solved by technology

This action mode caused the waiting of the manipulator feeding process, resulting in the loss of equipment efficiency

At the same time, the ejecting mechanism and the receiving mechanism caused the conveying line to be too long, and the action of ejecting materials is also likely to cause the collapse of the workpiece, resulting in defective products.
