Description
Technical field
The present invention relates to metal lographic examination equipment frock technical field, be specially metallographic pre-grinding, grind and use specimen holder.
Background technology
Metallographic microscope is the institutional framework of observing the check metal inside with the method for Metallographic Analysis; Can check loose, the pore of material, slag inclusion structural homogenity, crackle etc.; Metallographic Analysis can also provide the adjustment operation and revise the basis of technological parameter; Instructing and produce, is a kind of important detection means during electromagnetic wire is produced, and therefore the metallographic specimen in early stage is made and seemed particularly important; Yet the metallographic pre-grinding machine and the grinder that provide at present are not equipped with the specimen holder frock; Only depend on manual work to hold pre-grinding and grinding that the copper boom end carries out copper bar sample, be difficult to guarantee that sample carries out pre-grinding and grinding at grade continuously, can not reach the requirement of metallographic test sample.
Summary of the invention
To the problems referred to above, the invention provides metallographic pre-grinding, grind and use specimen holder, it is simple in structure, and is easy to operate, guarantees that sample carries out continuously grinding at grade.
Its technical scheme is such; It comprises base, it is characterized in that: it also comprises transmission case, main shaft and grip device, and said transmission case is installed on the rotation platform on said base top through transverse support bar; Said main shaft vertically passes said transmission case; Said grip device is installed on said main shaft lower end, and said main spindle box internal upper part is equipped with the worm and gear structure, and said worm and gear structure and said main shaft upper end are in transmission connection through rack-and-pinion.
It is further characterized in that: said worm and gear structure comprises worm gear, worm screw and turning handle; Said worm screw one end is connected in said transmission case sidewall upper and with said turning handle through bearings; Said worm gear vertically is installed on said transmission case sidewall; Said worm gear and the engagement of said worm screw profile of tooth; Said main shaft upper side is equipped with tooth bar; Said main shaft upper end tooth bar and the engagement of said worm gear profile of tooth; Said grip device comprises fixed head, and said fixed head and said main shaft lower end are through being threaded; Said fixed head lower end is equipped with arc fixed teeth piece; Said arc fixed teeth piece two ends are connected with movable arc tooth piece through bolt respectively.
Specimen holder is used in metallographic pre-grinding of the present invention, grinding; It is simple in structure, and sample clamps reliably, and is easy to operate; Make sample can carry out pre-grinding and grinding at grade continuously; Guarantee the flatness and the uniformity of sample flour milling, improved the surface quality in sample cross section, guaranteed the required sample requirement of metallographic test.

Fig. 1 is metallographic pre-grinding of the present invention, grinds and use the specimen holder structural representation;
Fig. 2 is metallographic pre-grinding of the present invention, grind A with grip device in the specimen holder to structural representation.
The specific embodiment
See Fig. 1; Metallographic pre-grinding of the present invention, grind that it comprises base 1, transmission case 9, main shaft 11 and grip device with specimen holder; Transmission case 9 is installed on the rotation platform 2 on base 1 top through transverse support bar 3, and main shaft 11 vertically passes transmission case 9, and grip device is installed on main shaft 11 lower ends; In the main spindle box 11, top is equipped with the worm and gear structure, worm and gear structure and main shaft 11 upper ends are in transmission connection through rack-and-pinion.The worm and gear structure comprises worm gear 7, worm screw 6 and turning handle 4; Worm screw 6 one ends are supported in transmission case 9 sidewall upper through bearing 5 and are connected with turning handle 4; Worm gear 7 vertically is installed on transmission case 9 sidewalls; Worm gear 7 and the engagement of worm screw 6 profiles of tooth; Main shaft 11 upper side are equipped with tooth bar 8; Main shaft 11 upper end tooth bars 8 and the engagement of worm gear 7 profiles of tooth; Grip device comprises fixed head 12, and fixed head 12 and main shaft 11 lower ends are through being threaded; Fixed head 12 lower ends are equipped with arc fixed teeth piece 13; Arc fixed teeth piece 13 two ends are connected with movable arc tooth piece 16 through bolt 14 respectively.Among Fig. 1,10 is the main shaft support frame, and it plays the effect of support, spacing main shaft 11; Among Fig. 2,15 is sample.
When apparatus of the present invention are used, sample 15 vertically is clamped between arc fixed teeth piece 13 and the movable arc tooth piece 16, the bolt 14 of screwing clamps sample; Transmission case 9 can be done 360 ° rotation at rotation platform 2 through transverse support bar 3, thereby regulates the contact position of sand paper in sample 15 and pre-grinding, the grinder, thereby improves the utilization rate of sand paper; In pre-grinding, when grinding; Manual rotation turning handle 4; Thereby the profile of tooth engaged transmission of the transmission between drive worm screw 6 and the worm gear 7 and worm gear 7 and main shaft upper gear rack 8 realizes the feed motion of sample 15, guarantees friction suitable between the sand paper in sample 15 and pre-grinding, the grinder simultaneously; Prevent further to guarantee the Grinding Quality in sample cross section because of the havoc sand paper that rubbed.
