Pneumatic double-bit bench drill capable of realizing automatic feeding

Abstract

The invention discloses a pneumatic double-bit bench drill capable of realizing automatic feeding. The bench drill comprises a bench drill body and a feeding mechanism, wherein the bench drill body comprises a double-bit mechanism and a lifting mechanism; the double-bit mechanism comprises a mounting disk, a spindle, a drive wheel, a first transmission shaft, a first driven wheel, a first bit, a second transmission shaft, a second driven wheel and a second bit; the spindle drives the first bit and the second bit synchronously to rotate; the feeding mechanism comprises a frame body, a feeding hopper, a stop piece, a discharging hopper, a transfer wheel and an air cylinder; a trough is formed in the peripheral wall of the transfer wheel; a first slide block for clamping a workpiece in the trough, a first guide rail, a clamping air cylinder for driving the first slide block to slide back and forth, a second slide block for pressing the workpiece in an ejection manner, a second guide rail as well as a discharging air cylinder for driving the second slide block to slide back and forth are arranged on the transfer wheel. The double-bit bench drill can realize automatic feeding, clamping and discharging.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a pneumatic automatic feeding double-head bench drill. Background technique [0002] There is a circular transmission shaft, the two ends of which are provided with symmetrical through holes radially penetrating through the shaft body. The traditional processing method is to use a bench drill to drill one end and then drill the other end. The disadvantage of this processing method is that : The first requires two procedures, and the second is to make the two holes symmetrical in order to make the two holes symmetrical, and accurate positioning is required, which greatly increases the difficulty of the process. In addition, there is no automatic feeding and discharging mechanism in the traditional processing method, resulting in slow processing efficiency. Contents of the invention [0003] The object of the present invention is to provide a pneumati...

Problems solved by technology

[0002] There is a circular transmission shaft, the two ends of which are provided with symmetrical through-holes that run through the shaft body in the radial direction. The traditional processing method is to use a bench drill to drill one end and then drill the other end. The disadvantage of this processing method is that : First, two processes are required, and second, when processing the other end, in order to make the two holes symmetrical, accurate positioning is required, which greatly increases the difficulty of the process

In addition, there is no automatic feeding and discharging mechanism in the traditional processing method, resulting in slow processing efficiency
