A kind of grinding and polishing anchor clamps that are used to process square block crystalline material sample
Technical field
The utility model relates to a kind of grinding and polishing anchor clamps that are used to process square block crystalline material sample, belongs to the materials processing technical field of tooling clamps.
Background technology
At present, in the grinding and polishing processing of the undersized square block crystalline material sample of centering, usually adopt hot wax or rosin etc. that sample is bonded in a cylindrical iron block bottom, and with iron block put into one the collimation steel sleeve, be placed on together then on the grinder work top, the rotation by the grinder table top drives sample and cooperates the grinding and polishing work of realization to sample with two passive runners of grinder together with the collimation sleeve.The shortcoming of using this kind anchor clamps to exist is: 1. can not closely cooperate between cylindrical iron block and the collimation sleeve, what cooperate is too tight, because contact area is bigger, cause between cylindrical iron block and the sleeve frictional force bigger, cylindrical iron block often can not be free to slide in sleeve, if gap between the two causes the original upper and lower surface of sample incomplete when parallel, the use that is difficult to by anchor clamps is that it obtains revising.Cylindrical in addition iron block can not get guaranteeing with the vertical precision that has not closely also caused between machined surface and the side that cooperates that collimates between the sleeve, reduces the qualification rate of workpiece.2. add man-hour, workpiece and anchor clamps need bonding, the monocrystalline workpiece of some heat shock resistance differences is easy to be scalded by hot wax and rosin and splits, after machining, workpiece also causes fragmentation easily when taking off, in addition, manual bonding workpiece is not easy to guarantee the parallel of workpiece and cylindrical iron block bottom face, thereby has reduced machining accuracy to a certain extent.

Described piece-holder pincers are round outside but spuare inside cylindrical tubes, the face of cylinder is provided with 4 equally distributed collimation guide-track grooves, the centre is provided with a foursquare hole that is used for place work piece, be provided with holding screw on two mutually perpendicular adjacent surfaces of square hole, this holding screw clamps or does not expose when unclamping the collimation guide-track groove working face of piece-holder pincers to workpiece; Be provided with 4 backing plates in the piece-holder pincers.
Described counterweight support is a cylinder with a lid, and the barrel surface of cylinder is provided with 4 equally distributed collimation guide-track grooves, and the cylinder center is provided with one and is connected, is parallel to the scale of cylinder axis with the cylinder lid.
Described collimation sleeve is the cylinder of an end face perpendicular to axis, inwall be provided with 4 equally distributed, with the corresponding collimation guide rail of collimation guide-track groove of piece-holder pincers, the collimation sleeve contacts an end and is provided with 12 equally distributed sewage draining exits of being convenient to grind the waste material discharge with the grinder working face.
During use, behind holding screw and backing plate firm grip workpiece, earlier the piece-holder pincers are put into the collimation sleeve, to collimate sleeve again is placed on the working face of grinder, then the counterweight support is put into the collimation sleeve, place counterweight as required on the counterweight support, and a whole set of anchor clamps are moved between two passive runners of polisher lapper, can start then that polisher lapper grinds or polishing.The piece-holder pincers can cooperate by holding screw and backing plate to be realized the different size workpiece is carried out clamping; The collimation sleeve contacts the discharge that the sewage draining exit of an end setting can conveniently grind waste material with the grinder working face.
The utility model employing keyway cooperates the frictional force that reduces between piece-holder pincers and the collimation sleeve, can guarantee effectively that gripper clamp freely does vertical mobile perpendicular to the grinder working face in the sleeve at collimation, adopt the holding screw fixation workpiece to avoid with hot wax and the required complicated procedures of forming of rosin fixation workpiece, and have simple in structure, easy to use, dependable performance, long service life and can effectively guarantee workpiece machining accuracy, improve the advantage of working (machining) efficiency.

The specific embodiment
Embodiment:
Structure of the present utility model is made up of piece-holder pincers 10 and collimation sleeve 9 and counterweight support 11 as shown in drawings, and piece-holder pincers 10 all are installed in the collimation sleeve 9 with counterweight support 11, and counterweight support 11 is positioned at piece-holder and clamps 10 tops; Piece-holder pincers 10 are parallel to the axis that collimates sleeve 9 with the axis of counterweight support 11, the end end face that collimation sleeve 9 contacts with the grinder working face is perpendicular to the axis of collimation sleeve 9, the collimation guide rail 4 of collimation sleeve 9 all is parallel to the axis that collimate sleeve 9 with the collimation guide-track groove 1 of piece-holder pincers 10 and counterweight support 11, piece-holder clamp be used in 10 place work piece 8 square hole 2 inwalls in twos intersection be parallel to the axis that collimates sleeve 9.
Described piece-holder pincers 10 are round outside but spuare inside cylindrical tubes, the face of cylinder is provided with 4 equally distributed collimation guide-track grooves 1, the centre is provided with a square hole 2 that is used for place work piece 8, be provided with holding screw 3 on 2 two mutually perpendicular adjacent surfaces of square hole, the 3 pairs of workpiece of this holding screw clamp or do not expose when unclamping the working face of the collimation guide-track groove 1 of piece-holder pincers 11; Can place 4 standard cushion plate 7 as required in the piece-holder pincers 10.
