FIG. 1 is a schematic cross-sectional view of an embodiment of the present utility model; FIG. 2 is a schematic view of a partly sectional structure of an elastic sleeve according to an embodiment of the present utility model.
Detailed Description
In order to further understand the technical scheme of the utility model, the technical scheme of the utility model is clearly and completely described by the embodiment and the attached drawings.
As shown in fig. 1 and 2. In an embodiment of the utility model, the gear grinding device for the shaft parts comprises an elastic sleeve 1, a locking sleeve 3, a round nut 2 and the like. In this embodiment, the workpiece is a shaft-like part.
One end of the elastic sleeve 1 is provided with a clamping part 1b, a corresponding part of one end of the clamping part 1b of the elastic sleeve 1 close to the ball head is provided with an external thread part 1a, and an inner hole 1c of the clamping part 1b of the elastic sleeve 1 is in clearance fit with a positioning excircle of the workpiece 4 to be processed.
The part of the outer circumferential wall of the clamping part 1b corresponding to the locking sleeve 3 is provided with a conical surface 1b1, the inner hole circumferential wall of the part of the locking sleeve 3 corresponding to the outer conical surface 1b1 of the clamping part 1b is provided with a conical surface 3a, the inner hole conical surface 3a of the locking sleeve 3 and the conical direction of the outer conical surface 1b1 of the clamping part 1b are opposite to each other, and the locking sleeve 3 is matched and sleeved on the elastic sleeve 1 through the inner hole conical surface 3a and the outer conical surface 1b1 of the clamping part 1b of the elastic sleeve 1.
The corresponding end wall surface of the round nut 2 is connected with the corresponding end surface of the locking sleeve 3 in a surface contact manner, and the round nut 2 is simultaneously in threaded connection with the elastic sleeve 1 through the external thread part 1a of the elastic sleeve 1.
When the locking sleeve is used, the locking sleeve 3 is arranged at one end of the clamping part 1b of the elastic sleeve 1, the round nut 2 is screwed into the external thread part of the elastic sleeve 1, the workpiece 4 is arranged in the inner hole 1c of the elastic sleeve phi 60, the round nut is rotated, one end face of the round nut is propped against the corresponding end face of the locking sleeve, the locking sleeve moves towards the workpiece along with the screwing of the round nut, and the clamping jaw of the clamping part 1b of the elastic sleeve is forced to shrink under the action of the mutually matched conical surfaces of the elastic sleeve and the locking sleeve, so that the positioning excircle of the workpiece is locked. After the workpiece is locked, the lower center of the machine tool is Kong Dingzhu at the center of the spherical head S phi 40 of the elastic sleeve 1, the upper center of the machine tool props against the central hole on the workpiece, and the hydraulic expansion sleeve of the machine tool is clamped to the spherical head S phi 40 of the elastic sleeve 1, so that the grinding machining can be realized.
It will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made hereto without departing from the spirit and scope of the utility model and that the described embodiments are merely illustrative of some, rather than all, of the embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
