Description
Technical field
The invention belongs to precise grinding polisher equipment, specifically is a kind of novel precision grinding polishers that is used for semi-conducting material, ceramic material and metal material sample.
Background technology
In the common metallographic-sample polisher structure, the rotation of driven by motor mill, rotating speed is very fast, generally is provided with one or several fixed rotating speed, need hand sample or material containing piece during work, carries out grinding and polishing on sand paper or polishing cloth.Main abrasive metal of this polishing machine or ceramic sample, simple in structure, easy to operate.Because artificial hand-held sample, sample grinds partially easily, and stock removal also is difficult to accurate control.Domestic existing precise grinding polisher adopts the anchor clamps clamping finishing in two to three orientation to encircle mostly, places the material containing piece in the ring, and sample is adhered to below the material containing piece, mainly relies on material containing piece deadweight grinding-material, and what have then need hand the material containing piece; When the sample upper and lower surface depth of parallelism is lower or in uneven thickness, sample very easily grinds partially, and stock removal is also wayward.The precise grinding polisher of external report, mill adopt the pressure between liftable mechanism or employing spring pressue device adjusting mill and the workpiece, and amount of grinding can not accurately be controlled; When the sample flatness was lower or in uneven thickness, also mill was inclined to one side easily for sample.For function semi-conducting material or other functional material, sample thickness and the photoelectricity of upper and lower surface depth of parallelism appreciable impact material and the test of other performance data.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome above-mentioned shortcoming, guarantee the sample upper and lower surface depth of parallelism, accurately control the novel precision grinding polishers of stock removal.Its technical scheme is:
A kind of novel precision grinding polishers, comprise the polishing disk and the drive unit thereof that are provided with abrasive polishing materials, be positioned at the polishing disk below and take the frame at the mouth of a river and the secured adjusted device of sample out of, it is characterized in that: the secured adjusted device of sample comprises base, lead parallel to each other and precision lead screw, be parallel to taking over a business and mid-game of polishing disk, wherein precision lead screw through bearing vertically be installed on and base between, on the lead, following two ends by bolt respectively with take over a business, the base vertical fixing connects, mid-game be installed in and base between and be positioned at the top of polishing disk, its through hole and lead matched in clearance, its screwed hole and precision lead screw are made into the bolt and nut pair, and the upper end of precision lead screw is equipped with handle; The center of mid-game is provided with suspension ring, is connected to form balance weight mechanism with pulley mechanism, counterweight on taking over a business by steel wire rope; Mid-game is provided with the guide rail of arranging radially, and guide rail is provided with equidistant tapped blind hole, and travelling carriage is installed on the guide rail and along guide rail and slides; The material containing piece is embedded in second bearing, and second bearing is placed in the travelling carriage, and the two is a matched in clearance; Sample is fixed on the bottom surface of material containing piece; Material containing piece inside is hollow structure, places some balancing weights in the cavity.
Described novel precision grinding polishers, mid-game are provided with the one or more of guide rails of radial arrangement, and every guide rail is provided with one or more travelling carriage.
Described novel precision grinding polishers, second bearing and travelling carriage form stopper rod-tube-in-tube structure.
Described novel precision grinding polishers is provided with the photoelectricity micrometer, and the initiating terminal of photoelectricity micrometer is screwed on taking over a business, and measures display box and is fixed in the mid-game.
The present invention compared with prior art, its advantage is:
1, owing to second bearing that is inlaid with the material containing piece is placed in travelling carriage central authorities, travelling carriage is fixed on the guide rail, the two is that matched in clearance forms stopper rod-tube-in-tube structure for second bearing and travelling carriage, and second bearing can slide and not run-off the straight by easy on and off.Sample is fixed on the bottom surface of material containing piece, and when the lower surface of sample, that is grinding face is when departing from the parallel surface of polishing disk, and this structure can give effective correction, has guaranteed the depth of parallelism of sample upper and lower surface.
2, the material containing piece is embedded in second bearing of selecting, and this second bearing is placed in travelling carriage central authorities, and the two is a matched in clearance.When the lower surface grinding of sample, produce frictional force between lower surface and the abrasive polishing materials; When producing certain moment if the frictional force that is subjected on the grinding face is uneven with respect to material containing piece central axis, sample and material containing piece can rotate.
3, can be provided with a plurality of travelling carriages on every of mid-game guide rail, the radial position of sample in mid-game just can be adjusted like this, and No. one time clamping is installed a plurality of samples, has improved the utilization rate of abrasive polishing materials or other removing material.Polishing has greatly improved the polishing efficiency of polishing machine in the time of a lot of samples.
4, the equipped handle in precision lead screw upper end, turning handle can make mid-game move both vertically up and down along lead, thereby can control the stock removal of sample.
5, material containing piece inside is hollow structure, can place some balancing weights in the cavity, regulates the pressure that is applied on the sample by deadweight and the number of regulating the material containing piece like this, controls grinding speed with this.
This equipment can prevent effectively that sample mill is inclined to one side, accurately controls stock removal, and material expends less and the efficient height.
