Abstract
The invention discloses a drilling jig for a front-axle lock bolt hole. The drilling jig comprises a jig body, a drill plate, a screw clamping mechanism, a cylinder ejecting rod mechanism and a link platen clamping mechanism. The drill plate is fixed to the upper surface of the jig body and provided with a horizontal channel and a vertical channel. The bottom of the vertical channel is communicated with the horizontal channel, and the top of the vertical channel is an opening in the upper surface of the drill plate. One end of the horizontal channel is an opening in the side surface of the drill plate. A positioning mandrel is arranged in the horizontal channel. The screw clamping mechanism partially penetrates through the vertical channel and abuts against the positioning mandrel. The cylinder ejecting rod mechanism comprises a cylinder, a cylinder contact and an ejecting rod. The drill plate is provided with an ejecting rod channel parallel to the horizontal channel. The ejecting rod is arranged in the ejecting rod channel, and one end of the ejecting rod is assembled on the cylinder. The cylinder contact is arranged on the drill plate. A horizontal moving device makes contact with the cylinder contact when moving a platen to release a compressed workpiece to be machined, and the ejecting rod is driven to push the workpiece to be machined. The drilling jig has the advantage that as the platen is in linkage with a cylinder reversing start switch, releasing and discharging are fast.
