Summary of the invention
Object of the present invention is exactly to provide the heavy duty rail head sample polishing fixture that a kind of structure is simple, efficiency is high, security performance is good.
For achieving the above object, heavy duty rail head sample polishing fixture designed by the present invention, comprise disk clamp body, described disk clamp body is coaxially fixed with the chuck adapter of hollow structure, removable connecting axle is coaxially installed with in described chuck adapter, described disk clamp body is circumferentially evenly distributed with for setting the sample groove that need polish heavy duty rail head, the circumference side of described disk clamp body is provided with the holding screw communicated with sample groove.
Further, described connecting axle the latter half of being positioned at chuck adapter is tubular construction, its barrel is provided with the oval through hole and bearing pin through hole that intersect vertically, is provided with connection bearing pin in described bearing pin through hole; The wall of described chuck adapter is provided with the lock shaft through hole corresponding with oval through hole, is plugged with lock shaft in described lock shaft through hole and oval through hole, the middle part of described lock shaft is provided with locking draw-in groove, described locking draw-in groove be connected bearing pin snap-fit engagement; Back-moving spring is provided with bottom described connecting axle and between chuck adapter intracavity bottom.Like this, can dismantle and install connecting axle and chuck adapter by extracting bearing pin.
Further, one end of described lock shaft is provided with column handle, described chuck adapter is positioned at lock shaft through hole end and is provided with the handle mounting groove corresponding with column handle.Like this, write off axle is inserted after increasing handle convenient.
Further, described chuck adapter and disk clamp body are fixed as one by the connecting bolt being arranged on its center.
Shop bolt is provided with between the mating surface of further, described chuck adapter and disk clamp body.
Further, be provided with installation base bottom described chuck adapter, described disk clamp body is provided with the installation groove corresponding with installation base.Like this, chuck adapter can more firmly be arranged on disk clamp body.
Further, the top of described connecting axle is provided with the annular slot in order to be connected with metallographic sample grinding machine.Can better be connected with metallographic sample grinding machine like this.
Further, the quantity of described sample groove is three.
Compared with prior art, the invention has the advantages that: designed heavy duty rail head sample polishing clamp structure is simple, easy installation and removal, what exist when avoiding manual test can not ensure the quality of products and safe problem, reduces the equipment cost in large quantities of process of the test and human cost.
