Drill jig for plow colter speed-changing gear box

Abstract

The invention discloses a drill jig for a plow colter speed-changing gear box. The drill jig comprises a base, a drill plate, an end face positioning assembly, a lateral positioning block, an axis endpositioning assembly and a press piece, wherein the drill plate is fixed to the upper side of the base through upright columns, and a workpiece is located between the drill plate and the base; the end face positioning assembly is connected to the bottom of the drill plate and used for limiting a to-be-defined end face to be parallel to the end face of the drill plate; the lateral positioning block is connected to the bottom of the drill plate and used for limiting the degree of freedom of the displacement, in the X direction, of the workpiece; the axis end positioning assembly is fixed to thetop of the base and used for positioning the center axis of the workpiece; the press piece is located on the top of the base and used for pressing the workpiece between the press piece and the drillplate. According to the unique appearance structure of the workpiece, the structure of the jig is simplified under the condition that the end face drilling processing requirements are met, therefore,the loading and clamping speed is greatly increased, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to the technical field of clamping tools, in particular to a coulter gear gearbox drilling machine clamp. Background technique [0002] The box structure of the coulter gear box (hereinafter referred to as the workpiece) has a boss slope on the circumferential side. When the mounting surface on the workpiece circumference side is processed, the boss slope will affect the positioning of the workpiece, so use Ordinary plane clamps cannot achieve accurate positioning and clamping, and often need to use many auxiliary tools or use multiple angles superimposed, the clamping speed is greatly reduced, the structure of the clamping tool is complex, and the processing cost is high. Therefore, it is necessary to design a suitable for Clamping tool for the box structure of the coulter gear box. [0003] The present invention is a clamping tool designed for the drilling process o...
