Description
Technical field
The present invention relates to a kind of frock clamp, be specifically related to a kind of centralizer that is used for the cylindrical that involute spline overlaps is carried out finish turning processing.
Background technology
Shown in Figure 1 is a kind of involute spline cover commonly used on the Hooke power transmission shaft, there is certain run-out tolerance requirement at its cylindrical Φ B and Φ C two places with respect to the pitch circle (diameter is PCD) of internal spline, adding man-hour, need come this two places cylindrical of finish turning as the centering benchmark with the pitch circle of internal spline.
But, if adopt the difficult run-out tolerance requirement that guarantees Φ B and Φ C two places simultaneously of traditional plain clamp; If adopt liquid to mould the anchor clamps of internal expanding structure or front and back Tensioning structure, though can reach the run-out tolerance requirement at two places, but or the cost height, or complex structure, difficulty made.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of lathe centralizer simple in structure, can be used for the cylindrical of finish turning involute spline cover, to overcome the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of centralizer that is used for involute spline cover finish turning cylindrical, comprise mandrel, fixing external splines cover, rotate external splines cover and impeller-hub, described fixedly external splines cover, be equipped with external splines on the cylindrical of rotation external splines cover, fixedly the external splines cover is enclosed within the outside of mandrel and fixedlys connected with mandrel, the two ends of mandrel are all from fixedly exposing the external splines cover, the latter half that rotates the external splines cover is enclosed within the front end of mandrel, the first half that rotates the external splines cover is enclosed within the rear end of impeller-hub, leave the gap between the front end of mandrel and the rear end of impeller-hub, rotate the external splines cover and fixedly contact by a pair of inclined-plane between the external splines cover, the front end of impeller-hub is provided with flange and contacts with the front end face that rotates the external splines cover.
Preferably, the rear end of mandrel is fixedly connected with ring flange.
Preferably, the front end center of impeller-hub is provided with taper hole.
Preferably, described impeller-hub is connected with the front end of mandrel by a screw, between impeller-hub and the described screw for being slidingly matched.
The invention has the beneficial effects as follows: by anchor clamps of the present invention, spline package to be processed can be clipped on the lathe, fixedly external splines cover on the anchor clamps, the external splines that the rotation external splines puts can match with the internal spline on the spline housing to be processed, when anchor clamps are clamped between lathe spindle and tailstock thimble, between external splines cover and the rotation external splines cover certain relatively rotating can take place fixedly, so just can eliminate the fit clearance between they and the spline housing to be processed, thereby guarantee the axiality of the pitch circle and the lathe spindle of spline housing internal spline to be processed, and then guarantee the circumference run-out tolerance requirement of the cylindrical process with respect to the internal spline pitch circle.Compare simple in structure, advantage of low manufacturing cost that the present invention has with existing centralizer.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is a kind of processing request schematic diagram of involute spline cover.
Fig. 2 is the structural representation that the present invention is used for the centralizer of involute spline cover finish turning cylindrical.
The specific embodiment
As shown in Figure 2, a kind of centralizer that is used for involute spline cover finish turning cylindrical of the present invention comprises mandrel 2, fixedly external splines overlaps 5, rotates external splines cover 7 and impeller-hub 9, fixedly is equipped with external splines on the excircle of external splines cover 5 and rotation external splines cover 7.Fixedly external splines cover 5 is enclosed within the outside of mandrel 2 and fixedlys connected with mandrel 2 by pin 3, the two ends of mandrel 2 are all from fixedly exposing the external splines cover 5, the front end of mandrel 2 inserts in the latter half that rotates external splines cover 7, the first half that rotates external splines cover 7 then is enclosed within the rear end of impeller-hub 9, leave certain clearance 13 between the rear end of the front end of mandrel 2 and impeller-hub 9, allow impeller-hub 9 certain axially-movable to be arranged with respect to mandrel 2, the front end of impeller-hub 9 is provided with flange 10 and contacts with the front end face that rotates external splines cover 7, thereby can promote to rotate 7 axially-movables together of external splines cover.
The rear end of mandrel 2 is fixedly connected with ring flange 1, can be connected with lathe spindle; The front end center of impeller-hub 9 is provided with taper hole 12, can match with the rotation thimble 11 of lathe tailstock.When anchor clamps clamping of the present invention is between lathe spindle and thimble, mandrel 2 and the axis of impeller-hub 9 and the dead in line of lathe spindle.
Fixedly the external splines barrel that overlaps 5 front ends is provided with a v-depression 15, the relevant position that the rotation external splines overlaps 7 rear end barrels then is provided with a V-arrangement projection 14, v-depression 15 only contacts at 6 places, a pair of inclined-plane with V-arrangement projection 14, in addition, fixedly external splines cover 5 does not contact with other position of rotating external splines cover 7.
When spline housing 4 to be processed by clamping on anchor clamps of the present invention the time, the internal spline of spline housing 4 to be processed and fixing external splines cover 5, the external splines that rotates external splines cover 7 is meshed, utilize the rotation thimble 11 of lathe tailstock to hold out against impeller-hub 9 then, impeller-hub 9 promotes to rotate 7 axially-movables together of external splines cover, since fixedly external splines cover 5 with contact by the inclined-plane between the rotation external splines overlaps 7, the reaction force that produces on inclined-plane 6 can promote to rotate the rotation that external splines cover 7 is made a minute angle, overlap relatively rotating between 5 just because of rotating external splines cover 7 with fixing external splines, the moment of torsion that they act on the spline housing 4 to be processed is opposite, this a pair of opposite moment of torsion just is the equal of a kind of clamping force, can eliminate the gap between anchor clamps and the spline housing to be processed 4.That is to say, when rotating external splines cover 7 and fixedly relatively rotating between the external splines cover 5, a side of rotating internal spline on external splines cover 7 and the spline housing 4 to be processed closely contacts, and fixedly on external splines cover 5 and the spline housing 4 to be processed another side of internal spline closely contact, so just with spline housing 4 stretchings to be processed.
After the gap between spline housing 4 to be processed and the anchor clamps is eliminated, use the lathe turning again, just than being easier to guarantee that the circumference of cylindrical beats.
Obviously, it is not unique form that the v-depression 15 that adopts in the present embodiment cooperates with V-arrangement projection 14, rotate external splines cover 7 and fixing external splines and overlap that the inclined-plane with other form contacts between 5 the end face, also can make and rotate external splines cover 7 and fixedly produce certain relatively rotating between the external splines cover 5, thereby produce the stretching effect.
In the present embodiment, impeller-hub 9 also is connected with the front end of mandrel 2 by a screw 8, all parts of forming anchor clamps of the present invention are linked together, can not hang down, between impeller-hub 9 and the screw 8 for being slidingly matched, thereby screw 8 can not hinder impeller-hub 9 relative mandrel 2 axially-movables within the specific limits.
