Abstract
The utility model provides an eccentric shaft grinding fixture. It includes main aspects eccentric positioning dish, tip eccentric positioning dish and locating pin, and the work piece passes through the locating pin to be installed on main aspects eccentric positioning dish and tip eccentric positioning dish, and first the clamping top dress that is provided with dress card work piece on the main aspects eccentric positioning dish is put, is provided with on the tip eccentric positioning dish to adorn the second that blocks the work piece and clamp top dress and puts, first clamp to put to clamp top dress with the second to top dress put corresponding setting. The utility model discloses a to top dress card, utilize the offset of fixture itself to offset by the offset between machined surface axle center and the machine tool rotary center, make by finished surface axle center and rotation axis coincidence, offset by the offset between finished surface axle center and the machine tool rotary center, realize the high precision grinding to process axle generating line.
Description
(1) technical field
This utility model relates to grinding processing tool design field, is specifically related to a kind of grinding fastener.
(2) background technology
Particularity due to F-559717 double-row full-complement self-locking cylindrical roller roller bearing product structure, bearing inner sleeve structure is eccentric mandrel, when grinding bias mandrel, the orientation axis that is installed is the most concentric with processed axle surface axis, cannot use the routine mode that is installed, on plain external grinding machine, the axle surface processed is carried out grinding, need, by means of a kind of eccentric fixture, eccentric shaft surface to be carried out grinding.
(3) summary of the invention
The purpose of this utility model is to provide a kind of eccentric shaft grinding fastener being capable of the high-precision grinding processing to eccentric working surface.
nullThe purpose of this utility model is achieved in that it to include greatly and holds eccentric location dish、Small end bias location dish and alignment pin，Workpiece is arranged on the eccentric location dish of big end and small end bias location dish by alignment pin，The top chucking device of the first couple of card engaging workpiece it is provided with on the dish of big end eccentric location，The top chucking device of the second couple of card engaging workpiece it is provided with on the dish of small end bias location，First pair of top chucking device and the second setting corresponding to top chucking device，It is provided with identical with the offset of workpiece itself between its axle center with workpiece、Offset in opposite direction，Alignment pin includes the alignment pin being symmetrically mounted on the eccentric location dish of big end and small end bias location dish a pair,The radius of big end eccentric location dish is more than the radius of small end bias location dish,The radius of first pair of top chucking device is less than second to top chucking device,And length is more than second to top chucking device,First pair of top chucking device and second is provided with draw-in groove on top chucking device.
This utility model uses and is installed to top, the offset utilizing fixture itself offsets the offset between machined surface axle center 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, it is achieved the high-precision grinding to processed axle bus.
(4) accompanying drawing explanation
Fig. 1 is this utility model structural representation.
(5) detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
nullIn conjunction with Fig. 1，The present embodiment includes holding greatly eccentric location dish 1、Small end bias location dish 2 and alignment pin 5，Workpiece is arranged on big end eccentric location dish 1 and small end bias location dish 2 by alignment pin，The top chucking device of the first couple 3 of card engaging workpiece it is provided with on big end eccentric location dish 1，The top chucking device of the second couple 4 of card engaging workpiece it is provided with on small end bias location dish 2，The first pair of top chucking device 3 with second to the top corresponding setting of chucking device 4，It is provided with identical with the offset of workpiece itself between its axle center with workpiece、Offset in opposite direction，Alignment pin includes the alignment pin being symmetrically mounted on the eccentric location dish of big end and small end bias location dish a pair,The radius of big end eccentric location dish is more than the radius of small end bias location dish,The radius of first pair of top chucking device is less than second to top chucking device,And length is more than second to top chucking device,First pair of top chucking device and second is provided with draw-in groove on top chucking device.
During operation, fixture large and small end bias location dish between top axle center and card engaging workpiece surface design an offset, make it identical with the offset of workpiece itself, in opposite direction, fix with alignment pin, when so lathe is to top being installed, it is possible to eliminate the offset between surface to be machined and machine tool rotary center so that workpiece surface to be machined and machine tool rotary centres.
