Description
Technical Field
The utility model relates to a digit control machine tool field especially relates to a clamping device of digit control machine tool.
Background
In the machining process, metal workpiece's material is various, it need carry out the centre gripping when processing on the numerical control machine tool, and traditional lathe adopts flat-nose pliers to press from both sides tightly more, and traditional flat-nose pliers clamping-force is not good to be controlled, judges by the workman by oneself more, and its clamping-force is too big leads to the fact the too big deformation of work piece local atress to influence the processing result, and the clamping-force undersize then easily causes the work piece to scrap because of the contact emergence displacement of cutter and work piece during processing, and its structure is unreasonable enough.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is not enough to the above-mentioned that prior art exists, provide a clamping device of numerical control machine tool rational in infrastructure.
The utility model aims at realizing through the following technical scheme:
a clamping device of a numerical control machine tool comprises flat tongs, a fixed base plate, a sliding base plate and a piezoresistive pressure sensor, wherein the side part of the flat tongs is provided with a fixed jaw, a thread groove is symmetrically distributed in the fixed jaw, the other side of the flat tongs is provided with a clamping jaw, the rear part of the clamping jaw is provided with a thread driving column, the clamping jaw and the fixed jaw are matched to form a clamping cavity, the top part of the fixed base plate is provided with a top plate, threaded holes are symmetrically distributed in the top plate, side plates are symmetrically distributed on two sides of the fixed base plate, sliding block grooves are uniformly distributed in the side plates, the middle part of the sliding base plate is provided with a cementing layer, the inner sides of the cementing layer are uniformly cemented with the piezoresistive pressure sensor, sliding side plates are symmetrically distributed on two sides of the sliding base plate, inner sliding blocks are uniformly distributed in the sliding side plates, the piezoresistive pressure sensor is pressed on the outer side surface of the fixed base plate, and the workpiece is placed in the clamping cavity.
The piezoresistive pressure sensor is connected with the signal receiver through the data line, the inner side face of the clamping jaw is pressed with the workpiece, and the side face of the workpiece is pressed with the outer side face of the sliding base plate.
Has the advantages that:
the gasket effect can be played in the cooperation of fixed backing plate and sliding pad board, prevent that regular jaw and work piece direct contact from leading to the bruise, glue inboard even bonding piezoresistive pressure sensor of layer, piezoresistive pressure sensor passes through the data line and is connected with the receiver, can set up pressure alarm value in receiver department, to different materials such as 45 steel, different materials such as 18Cr2Ni4WA are according to its yield limit value and set up, thereby prevent to lead to the too big deformation of work piece atress because of the clamp force is too big, and is rational in infrastructure, interior slider puts into the slider inslot and slides, can play the guide effect at the in-process of pressing from both sides tight work piece, and make piezoresistive pressure sensor both sides face can evenly atress, and is rational in infrastructure.
