Abstract
The invention discloses an internal grinding fixture for a thin-wall type hard alloy roller ring. The internal grinding fixture comprises an external sleeve, wherein an inner hole matched with an alloy roller ring to be processed is formed in the external sleeve; the external sleeve is coaxial with the inner hole; and at least three groups of fixing devices for applying an axial force on the alloy roller ring to be processed are arranged on the front end surface of the external sleeve. The internal grinding fixture disclosed by the invention has the advantages that the internal grinding fixture is fixed by adopting the axial force application, is simple in structure and convenient in operation and can be used for better fixing the alloy roller ring without damaging the alloy roller ring; and the work efficiency and the internal grinding precision are greatly improved.
Description
Technical field
The present invention relates to grinding jig in the thin wall type carbide roll ring.
Background technology
For wall thickness and the thin wall type alloy collars of diameter ratio greater than 1:15, when inner bore grinding, because product is more crisp, existing stationary fixture all is axial restraint, is easy to during use just product be done to split, and causes and scraps, endoporus process time, the operating efficiency of reduction have indirectly been improved.
Summary of the invention
The object of the present invention is to provide grinding jig in the thin wall type carbide roll ring, can effectively solve existing stationary fixture all is axial restraint, is used in the processing of thin wall type carbide roll ring, easily causes the cracked problem of collars.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: grinding jig in the thin wall type carbide roll ring, comprise outer sleeve, have the endoporus suitable with alloy collars to be processed in the described outer sleeve, described outer sleeve and endoporus coaxial line, the front end face of described outer sleeve are provided with at least three groups add axial force to alloy roller circulating application to be processed fixture.
Preferably, described fixture comprises catch and bolt, has the screwed hole suitable with bolt on the front end face of described outer sleeve, and described bolt passes catch and is arranged in the screwed hole; Fixture structure is simple, and is easy to operate, is easy to loading and unloading.
Preferably, the short 0.05 ~ 0.1mm of length of the Length Ratio of described endoporus alloy collars to be processed; The too short alloy collars can not being fixed, the alloy collars can rock and affect processing in front and back in outer sleeve, and the oversize alloy collars that can destroy when bolt clamps causes cracked.
Preferably, described fixture has four groups; Fixture is easily loose very little, can prolong the clamping time too much.
Preferably, described fixture is distributed on the front end face of outer sleeve; Clamping force is evenly distributed.
Compared with prior art, advantage of the present invention is: these anchor clamps adopt axial force distribution to fix, and are simple in structure, easy to operate, can be well fixing alloy collars, and be unlikely to the alloy collars is destroyed, improved greatly operating efficiency and interior mill precision.
Description of drawings
Fig. 1 is the structural representation of grinding jig in the thin wall type carbide roll ring of the present invention.
The specific embodiment
Consult Fig. 1 and be the embodiment of grinding jig in the thin wall type carbide roll ring of the present invention; grinding jig in the thin wall type carbide roll ring; comprise outer sleeve 1; have the endoporus 2 suitable with alloy collars to be processed in the described outer sleeve 1; described outer sleeve 1 and endoporus 2 coaxial lines; the front end face of described outer sleeve 1 is provided with four groups of fixtures that alloy roller circulating application to be processed added axial force; described fixture is distributed on the front end face of outer sleeve 1; described fixture comprises catch 3 and bolt 4; have the screwed hole 5 suitable with bolt 4 on the front end face of described outer sleeve 1; described bolt 4 passes catch 3 and is arranged in the screwed hole 5, the short 0.05 ~ 0.1mm of length of the Length Ratio of described endoporus 2 alloy collars to be processed.
The above only is specific embodiments of the invention, but technical characterictic of the present invention is not limited to this, and any those skilled in the art is in the field of the invention, and the variation of doing or modification all are encompassed among the claim of the present invention.
