Abstract
The invention provides an eccentric shaft grinding fixture which comprises a large-end eccentric positioning plate, a small-end eccentric positioning plate and a dowel pin, wherein a workpiece is arranged on the large-end eccentric positioning plate and the small-end eccentric positioning plate through the dowel pin; a first opposite vertex clamping device for clamping the workpiece is arranged on the large-end eccentric positioning plate; a second opposite vertex clamping device for clamping the workpiece is arranged on the small-end eccentric positioning plate; the first opposite vertex clamping device and the second opposite vertex clamping device are correspondingly arranged, and eccentric amount which is same with that of the workpiece and reverse in direction is arranged between the shaft centers and the workpiece. According to the eccentric shaft grinding fixture disclosed by the invention, the opposite vertex clamping is adopted, and the eccentric amount of the clamp body is utilized to balance out the eccentric amount between the shaft center of the machined surface and the rotary center of a machine tool, so that the processed surface shaft center is superposed with the rotary axis, the eccentric amount between the processed surface shaft center and the rotary center of the machine tool is balanced, and the high-precision grinding of the processed shaft bus is realized.
Description
(1) technical field
The present invention relates to mill processing tool design field, be specifically related to a kind of grinding fastener.
(2) background technology
Due to the particularity of F-559717 double-row full-complement self-locking cylindrical roller roller bearing product structure, bearing inner sleeve structure is eccentric mandrel, when the eccentric mandrel of grinding, be installed orientation axis and institute's machining shaft surface axis decentraction, the routine mode that is installed cannot be adopted on plain external grinding machine to carry out grinding to processed axle surface, need by means of the eccentric jig of one, grinding is carried out to eccentric shaft surface.
(3) summary of the invention
The object of the present invention is to provide a kind of eccentric shaft grinding fastener that can realize that the high-precision grinding of eccentric working surface is processed.
The object of the present invention is achieved like this: it comprises the eccentric positioning disk of large end, the eccentric positioning disk of small end and alignment pin, workpiece is arranged on the eccentric positioning disk of large end and the eccentric positioning disk of small end by alignment pin, the eccentric positioning disk of large end is provided with the top chucking device of the first couple of card engaging workpiece, the eccentric positioning disk of small end is provided with the top chucking device of the second couple of card engaging workpiece, the first pair of top chucking device to the corresponding setting of top chucking device, is provided with identical with the offset of workpiece itself, that direction is contrary offset with second between its axle center with workpiece.
The present invention adopts and is installed to top, utilize the offset between the offset counteracting machined surface axle center of jig itself and machine tool rotary center, make surface to be machined axle center and rotation axis coincident, offset between surface to be machined axle center and machine tool rotary center is cancelled, and realizes the high-precision grinding to institute's machining shaft bus.
(4) accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
(5) detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated:
Composition graphs 1, the present embodiment comprises the eccentric positioning disk 1 of large end, the eccentric positioning disk 2 of small end and alignment pin 5, workpiece is arranged on the eccentric positioning disk 1 of large end and the eccentric positioning disk 2 of small end by alignment pin, the eccentric positioning disk of large end 1 is provided with the top chucking device 3 of the first couple of card engaging workpiece, the eccentric positioning disk 2 of small end is provided with the top chucking device 4 of the second couple of card engaging workpiece, the first pair of top chucking device 3 to the corresponding setting of top chucking device 4, is provided with identical with the offset of workpiece itself, that direction is contrary offset with second between its axle center with workpiece.
During operation, at the eccentric positioning disk of the large and small end of jig to designing an offset between top axle center and card engaging workpiece surface, make it identical with the offset of workpiece itself, direction is contrary, fix with alignment pin, when such lathe is to top being installed, just can eliminate the offset between surface to be machined and machine tool rotary center, make workpiece surface to be machined and machine tool rotary centres.
Claims (1)
1. an eccentric shaft grinding fastener, it is characterized in that it comprises the eccentric positioning disk of large end, the eccentric positioning disk of small end and alignment pin, workpiece is arranged on the eccentric positioning disk of large end and the eccentric positioning disk of small end by alignment pin, the eccentric positioning disk of large end is provided with the top chucking device of the first couple of card engaging workpiece, the eccentric positioning disk of small end is provided with the top chucking device of the second couple of card engaging workpiece, the first pair of top chucking device with second to the corresponding setting of top chucking device, be provided with the offset of workpiece itself identical between its axle center with workpiece, the offset that direction is contrary.
