Abstract
The utility model relates to a bell-shaped housing self-centering expanding fixture to mainly solve the problem that an existing three-ball-pin type sliding end universal joint self-centering expanding fixture easily causes damage to an inner ball channel of a bell-shaped housing. The bell-shaped housing self-centering expanding fixture is characterized in that the shape of the outer end portion of a spring clip (3) is the same as the shape of the cross section of an inner hole of the bell-shaped housing (8), and the inner wall of the spring clip (3) is in spline fit with the conical section of a mandrel (1). The bell-shaped housing self-centering expanding fixture is improved based on the background technology, and the inner ball channel of the bell-shaped housing can not be damaged when the bell-shaped housing self-centering expanding fixture is used.
Description
Technical field
The utility model relates to a kind of lathe-use clamp, is specifically related to a kind of clutch can self-centering tensioning clamper.
Background technology
The tripod sliding end universal joint is a vitals on the automobile, the tripod sliding end universal joint mainly is comprised of clutch can and spider assembly, clutch can is the integral type structure, the general employing forged processing, its required precision is higher, and particularly the axiality between the external cylindrical surface of the inner cylinder face of clutch can and clutch can axial region directly affects the serviceability of universal joint.At present, when the axial region of lathe processing clutch can, the clamping of clutch can is general to adopt following dual mode: one, scroll chuck is stuck in the maximum inner diameter place in inner chamber three raceways of clutch can, then passes through the axle head of top top tight workpiece; This installation way is difficult to guarantee the axiality of clutch can inner cylinder face and clutch can axial region external cylindrical surface, and the clutch can qualification rate that processes is low, and the loading and unloading clutch can is wanted the degree of tightness three-jaw, and the clamping time is long, and production efficiency is low.Two, with top direct clamping on scroll chuck, with the top interior chamfering of withstanding the clutch can end, utilize the interior chamfering location of clutch can; Because the axiality of interior fillet surface and inner cylinder face also is to be difficult to guarantee when interior chamfer machining, does not therefore fundamentally solve the axiality problem of clutch can inner cylinder face and clutch can axial region external cylindrical surface.Thus, Chinese patent CN200920200094.1 discloses a kind of Three-ball-pin type sliding end universal joint self-centering tensioning fixture, these anchor clamps comprise axle, one end of axle is with the Morse tapering that cooperates with machine tool chief axis, the other end of axle is multidiameter and spring from inside to outside is housed successively, spring clip and clamping sleeve, spring clip and clamping sleeve all can endwisely slip along axle, cooperate for taper seat between the outer end of spring clip and the axle, the end face center of axle is equipped with the axial limiting bolt, and the end face of caging bolt is positioned at clamping sleeve and with the end face of clamping sleeve certain distance is arranged.In order to guarantee that clutch can does not skid when the turning, screw is installed on the axle, the head of screw stretches in three ball receways of clutch can and with clutch can and blocks mutually, by the screw transmitting torque.When clutch can by when chucking, start lathe or when stopping, under effect of inertia, between clutch can and the screw relative motion occur, the alley in the clutch can and screw bump easily cause the interior alley of clutch can to damage.
The utility model content
Easily cause the deficiency of the interior alley damage of clutch can in order to overcome existing Three-ball-pin type sliding end universal joint self-centering tensioning fixture, the utility model provides a kind of clutch can self-centering tensioning clamper, this clutch can self-centering tensioning clamper improves on the basis of background technology, can not cause in use the interior alley damage of clutch can.
The technical solution of the utility model is: a kind of clutch can self-centering tensioning clamper, comprise axle, spring, spring clip, clamping sleeve and caging bolt, one end of axle is with the Morse tapering taper shank that matches with machine tool chief axis, the other end of axle is multidiameter, spring, spring clip and clamping sleeve are installed on the axle successively, cooperate for taper seat between the outer end of spring clip and the axle, the outer end shape of spring clip is consistent with the cross sectional shape of clutch can endoporus, is spline fitted between the inwall of spring clip and the conical section on the axle.
Described clamping sleeve is provided with the elastic caoutchouc cover, and described elastic caoutchouc cover is corresponding with the outer face of spring clip.
The utlity model has following beneficial effect: owing to taking such scheme, in when, when skidding between spring clip and the clutch can relative displacement occuring, because it is larger that spring clip extend in the clutch can in the alley part and clutch can the contact area of alley, and the gap is less, thereby can not cause the interior alley damage of clutch can.

1-axle among the figure, 2-spring, 3-spring clip, 4-clamping sleeve, 5-caging bolt, 6-spline, 7-elastic caoutchouc cover, 8-clutch can.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of clutch can self-centering tensioning clamper, comprise axle 1, spring 2, spring clip 3, clamping sleeve 4 and caging bolt 5, one end of axle 1 is with the Morse tapering taper shank that matches with machine tool chief axis, the other end of axle 1 is multidiameter, spring 2, spring clip 3 and clamping sleeve 4 are installed on the axle 1 successively, cooperate for taper seat between the outer end of spring clip 3 and the axle 1, the outer end shape of spring clip 3 is consistent with the cross sectional shape of clutch can 8 endoporus, cooperates for spline 6 between the conical section on the inwall of spring clip 3 and the axle 1.Owing to taking technique scheme, axle 1 is installed on the machine tool chief axis, clutch can 8 is enclosed within outside the spring clip 3, push clutch can 8 to axle 1 with top dirt at the tail end of clutch can 8, the bottom surface of clutch can 8 inner chambers contacts with the outer face of clamping sleeve 4 and then promotes clamping sleeve 4 and inwardly slides, clamping sleeve 4 promotes spring clip 3 and inwardly slides, spring clip 3 opens, spring clip 3 is adjacent to the inner cylinder face of clutch can 8, realize radially automatically locating, partly and between the clutch can 8 there is certain gap in the interior alley that extend into clutch can 8 on the spring clip 3.When skidding between spring clip 3 and the clutch can 8 relative displacement occuring, the interior alley part that extend into clutch can 8 owing to spring clip 3 is larger with the contact area of clutch can 8 interior alleys, and the gap is less, thereby can not cause the interior alley damage of clutch can 8.In addition, adopt spline 6 to be connected between spring clip 3 and the axle 1, transmitting torque is steadily reliable.
Described clamping sleeve 4 is provided with elastic caoutchouc cover 7, and described elastic caoutchouc cover 7 is corresponding with the outer face of spring clip 3.Elastic caoutchouc cover 7 plays cushioning and protection.
