Description

The workpiece processing tool

Technical field

The present invention relates to the clamping tool for machine work technical field, specifically a kind of through the adjustment side-play amount, the ability machining center is apart from the workpiece processing tool of different square body workpiece.

Background technology

At present, in workpiece processing, we often run into picture pneumatic operated valve, hydraulic valve or the oil processing work with square bodies such as valves; Four planes of these processing works all need thread mill drilling, and these screwed holes are not at same Working position; Therefore during the screwed hole of workman on each plane of processing, all make a mold, four planes; Then need four molds, the screwed hole on plane of every then processing all need be installed in this workpiece on the mold; Its deficiency is: complicated operation, production efficiency are extremely low, the workpiece processing cost high and to changing mold each time, the precision of mold is all influential to workpiece, causes crudy poor.

Summary of the invention

The objective of the invention is to solve the deficiency of above-mentioned prior art, a kind of novel structure, easy to operate, production efficiency is high, processing cost is low, crudy is high, clamping precision is high workpiece processing tool are provided.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of workpiece processing tool is characterized in that being provided with pull bar, taper shank, mold body, tensioning screw, tensioning spring, backing plate, push pedal, top board, locking nut, adjustment screw, counterweight nut, screw, holding screw and packing ring, and taper shank is enclosed within on the pull bar; Taper shank upper end is connected with the mold body-fixed, and the mold body is formed the clamping space of Y datum level and Z datum level formation workpiece by workbench and two Y datum levels and two Z datum levels of being vertically fixed on the workbench upper surface; Backing plate is seated on the workbench in the clamping space, and backing plate is provided with detent, and workpiece is sitting on the detent; Detent is to be made up of XOZ plane, XOY plane and YOZ plane, is respectively equipped with positioning spiro pit on Y datum level and the Z datum level, and the opposite side of corresponding XOY plane is provided with top board; The opposite side on corresponding YOZ plane is provided with push pedal, and XOY plane is provided with tapped blind hole, and XOY plane fixes through screwed hole and the tapped blind hole on the XOY plane and the Y datum level that holding screw and packing ring pass on the Y datum level; The YOZ plane is with to pass the adjustment screw of the screwed hole on the Z datum level inconsistent, and through the locking nut location, and it is inconsistent that push pedal is passed screwed hole that push pedal is provided with and tensioning spring and XOY plane through tensioning screw; And through passing the inconsistent location of dog screw of the screwed hole on the Z datum level; Top board is inconsistent with the screw that passes the screwed hole on another Y datum level, and the balance of the counterweight nut alignment jig on screw, is beneficial to control the off-centre of anchor clamps; Make the workpiece lower surface through the XOZ plane positioning; Limited the three degree of freedom of workpiece, i.e. the moving of the rotation of the rotation of X axle, Y axle and Z axle, front end face is located through XOY plane; Rear end face is located through top board; The left side is through the YOZ plane positioning, and locate through push pedal the right side, has limited three degree of freedom; Be moving and the rotation of Z axle of the moving of X axle, Y axle, reach the principle of six point locations.

The present invention is owing to adopt said structure, have novel structure, easy to operate, production efficiency is high, processing cost is low, crudy is high, the clamping precision advantages of higher.
