The invention has the advantages of simple structure and convenient operation, and ensures continuous grinding of the specimen on one plane. The specimen holder comprises a base and is characterized by also comprising a transmission case, a main shaft and a holding device, wherein the transmission case is installed on a rotating platform at the upper part of the base through a transverse support rod; the main shaft vertically penetrates through the transmission case; the holding device is installed on the lower end of the main shaft; the upper part in the main shaft box is provided with a worm and gear structure; and the worm and gear structure is connected with the upper end of the main shaft through gears and racks in a transmission mode.
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 be to material loose, pore, the slag inclusion structural homogenity, crackles etc. are checked, Metallographic Analysis can also provide the basis of adjusting operation and revising technological parameter, instruct and produce, it is a kind of important detection means during electromagnetic wire is produced, therefore the metallographic specimen in early stage is made and is seemed particularly important, yet pre-grinding machine of the metallographic that provides at present and grinder are not equipped with the specimen holder frock, only depend on and manually hold pre-grinding and the 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
At 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, described transmission case is installed on the rotation platform on described base top by transverse support bar, described main shaft vertically passes described transmission case, described grip device is installed on described main shaft lower end, and described main spindle box internal upper part is equipped with the worm and gear structure, and described worm and gear structure and described main shaft upper end are in transmission connection by rack-and-pinion.
It is further characterized in that: described worm and gear structure comprises worm gear, worm screw and turning handle; Described worm screw one end is connected in described transmission case sidewall upper and with described turning handle by bearings; Described worm gear vertically is installed on described transmission case sidewall; Described worm gear and the engagement of described worm screw profile of tooth; Described main shaft upper side is equipped with tooth bar; Described main shaft upper end tooth bar and the engagement of described worm gear profile of tooth; Described grip device comprises fixed head, and described fixed head and described main shaft lower end are by being threaded; Described fixed head lower end is equipped with arc fixed teeth piece; Described arc fixed teeth piece two ends are connected with movable arc tooth piece by bolt respectively.
Metallographic pre-grinding of the present invention, grinding specimen holder, it is simple in structure, sample clamps reliably, 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.
Description of drawings
Fig. 1 is metallographic pre-grinding of the present invention, grinds and use the specimen holder structural representation;
Fig. 2 is that metallographic pre-grinding of the present invention, grinding use the A of 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 by transverse support bar 3, main shaft 11 vertically passes transmission case 9, 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 by 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 by 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 by 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 by 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, screws bolt 14 sample is clamped; Transmission case 9 can be done 360 ° rotation at rotation platform 2 by 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, realize the feed motion of sample 15, guarantee friction suitable between the sand paper in sample 15 and pre-grinding, the grinder simultaneously, prevent from further to guarantee the Grinding Quality in sample cross section because of the havoc sand paper that rubbed.
