Abstract
The utility model relates to a chuck for grinding and polishing a square block crystal. The chuck comprises a chuck body, wherein rectangular clamping holes are formed in the chuck body; a fastening bolt hole is formed in the chuck body by corresponding to the position of each clamping hole; a mounting groove is formed in the circumferential side wall of the chuck body; and the fastening bolt holes are formed in the chuck body at the bottom position of the mounting groove. Workpieces of different sizes are clamped through cooperation of a fastening screw and a base plate; the workpiece is fixed through the fastening screw, so that a complex process required for fixing the workpiece through hot wax and rosin is avoided, the chuck is simple in structure, convenient to use, reliable in performance and long in service life, the machining precision of the workpiece can be effectively guaranteed, and the machining efficiency is improved.
Description
Technical field
The utility model relates to crystal machining tool fixture technical field, especially a kind of square bulk crystals grinding and polishing chuck.
Background technology
At present, in the grinding and polishing processing of the undersized square block crystalline material sample of centering, usually it is following to adopt hot wax or rosin etc. that sample is bonded in a cylindrical iron block, and with iron block put into one the collimation steel sleeve, then be placed on together on the grinder work top, the sample that rotarily drives by the grinder table top cooperates realization to the grinding and polishing work of sample together with the collimation sleeve with two passive runners of grinder.Workpiece is adding man-hour, and workpiece and cylindrical iron block need bonding, and the poor monocrystalline workpiece of some heat shock resistances is easy to be scalded by hot wax and rosin and splits, and 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 to a certain extent passing rate of processing.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of square bulk crystals grinding and polishing chuck that can improve square bulk crystals grinding and polishing passing rate of processing is provided.
The technical scheme that provides according to the utility model, described square bulk crystals grinding and polishing chuck, it comprises chuck body, offer the folder hole that is rectangle in chuck body, in the chuck body of corresponding each folder hole position, offer fastening bolt holes, circumferential side wall in chuck body offers the installation groove, and described fastening bolt holes is opened on the chuck body that groove bottom land position is installed.
The two ends of the length direction in each folder hole cross section and middle part offer respectively a fastening bolt holes.
The utility model has been realized the clamping to the different size workpiece by the cooperation of holding screw and backing plate; Adopt the holding screw fixation workpiece to avoid with hot wax and the required complicated procedures of forming of rosin fixation workpiece, and simple in structure, easy to use, dependable performance, long service life and can effectively guarantee machining accuracy, the raising working (machining) efficiency of workpiece.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: this square bulk crystals grinding and polishing chuck, it comprises chuck body 1, offer the folder hole 2 that is rectangle in chuck body 1, in the chuck body 1 of corresponding each folder hole 2 position, offer fastening bolt holes 3, circumferential side wall in chuck body 1 offers installation groove 4, and described fastening bolt holes 3 is opened on the chuck body 1 that groove 4 bottom land positions are installed.
Two ends and the middle part of the length direction in each folder hole 2 cross section offer respectively a fastening bolt holes 3.
The square folder hole 2 of described chuck body 1 rim circumference uniform distribution, the number of folder hole 2 and distribution are all decided according to the size of clamp circle disk and square opening.
Described chuck body 1 is three fastening bolt holes 3 before, during and after the lateral surface of each square opening is provided with, and this fastening bolt holes 3 can be realized the clamping that is put in the workpiece in the square opening or unclamp.And this fastening bolt holes 3 bolt of screwing on, bolt is positioned at the installation groove 4 of clamp circle disk lateral surface, can't expose outside the chuck body 1.In addition, can place backing plate in the workpiece squeeze side, prevent the fastened screw crushing of square bulk crystals.
During work, behind the square bulk crystals in holding screw and the square folder hole 2 of backing plate firm grip, again chuck is put into the collimation sleeve, then counter weight device is put into the collimation sleeve, at last a whole set of anchor clamps are moved between two passive runners of polisher lapper, start polisher lapper and grind or polishing.
Claims (2)
