Description

Workpiece processing frock

Technical field

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

Background technology

At present, in workpiece processing, we often run into the picture pneumatic operated valve, hydraulic valve or oil are with the processing work of the square bodies such as valve, 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, then the screwed hole on plane of every processing all needs this workpiece is installed on the mold, and its deficiency is: complicated operation, production efficiency is extremely low, the workpiece processing cost is high, and to changing each time mold, the precision of mold is all influential to workpiece, causes crudy poor.

Summary of the invention

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

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

A kind of workpiece processing frock, it is characterized in that being provided with pull bar, taper shank, the mold body, tensioning screw, tensioning spring, backing plate, push pedal, top board, locking nut, adjustment screw, the counterweight nut, screw, holding screw and packing ring, taper shank is enclosed within on the pull bar, the taper shank upper end is fixedly connected with the mold body, the mold body is comprised of workbench and two Y datum levels and two Z datum levels of being vertically fixed on the workbench upper surface, Y datum level and Z datum level form the clamping space of workpiece, backing plate is seated on the interior workbench of clamping space, backing plate is provided with detent, workpiece is sitting on the detent, detent is by the XOZ plane, XOY plane and YOZ plane consist of, be respectively equipped with positioning spiro pit on Y datum level and the Z datum level, the opposite side of corresponding XOY plane is provided with top board, the opposite side on corresponding YOZ plane is provided with push pedal, XOY plane is provided with tapped blind hole, XOY plane passes screwed hole on the Y datum level and the tapped blind hole on the XOY plane and Y datum level through holding screw and packing ring and fixes, the YOZ plane is inconsistent with the adjustment screw of passing the screwed hole on the Z datum level, and locate through locking nut, 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, be 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, it is the rotation of X-axis, the rotation of Y-axis and the movement of Z axis, 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, locate through push pedal the right side, limited three degree of freedom, it is the movement of X-axis, the movement of Y-axis and the rotation of Z axis reach the principle of six point locations.

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