Abstract
The invention relates to a centering elastic internal-expanding clamp, relating to the machining field. The centering elastic internal-expanding clamp comprises a body and is characterized in that the body is a stepped boss; a tail-end boss is in sleeve joint with an elastic clamp sleeve; the elastic clamp sleeve can slide on the body and is connected with a mandrel at the center of the body via a pull pin; a spring retainer ring is in sleeve joint with the elastic clamp sleeve; a positioning ring is in sleeve joint with a boss adjacent to the elastic clamp sleeve on the body; a press ring is further sleeve joint with the boss; and the press ring is connected with a transition disc of a head-end boss of the body via a hex head screw. The centering elastic internal-expanding clamp has following beneficial effects: workpieces are installed and dismantled easily and clamped tightly; positioning is reliable so that machining precision of the workpieces is ensured; as for different-sized workpieces, elastic clamp sleeves are only needed to be replaced so that different workpieces are conveniently clamped; and fine interchangeability is achieved.
Description
Technical field
The present invention relates to field of machining, be specifically related to centring type elasticity internal expanding fixture.
Background technology
Development along with modern mechanical process technology, automobile hub axle tube product is progressively improved to hollow blank by original solid blanks, raw material not only saved by central siphon after so improving, decreases original drill centers, boring and bore hole operation, saves man power and material. And having portions of client pattern requirement central siphon endoporus not process at present, the popularization of through hole blank also adapts with the requirement of client. How processing for through hole blank rush defect (as wall deviation, oral area such as tear at the defect) from the heat eliminating blank process for machining, it is ensured that the cylindrical after machining and the axiality not processing endoporus require just to become the problem needing to solve.
Processing for through hole blank, owing in the course of processing, Workpiece clamping and location cannot ensure, thus causing the precision of work pieces process can not meet requirement, and owing to man-hour is wasted in the handling of part and installation two in the course of processing, cause production efficiency low, add production cost.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of workpiece loading and unloading easy, clamping, and location is reliable, uses scope wide, it may be achieved the clamping of different workpieces, the centring type elasticity internal expanding fixture that interchangeability is good.
Centring type elasticity internal expanding fixture of the present invention, including body, it is characterized in that, described body is stepped boss, end boss is socketed with an elastic jacket, described elastic jacket can slide on body and be connected with the axle being arranged on body central place by drawing pin, and outside elastic jacket, it is socketed with spring collar, boss adjacent with elastic jacket on described body is socketed with centring ring, also being socketed with a compacting ring on this boss, described compacting ring is connected with the transition disc being socketed in body head end boss by hex screw.
Preferably, body tip boss is a frustum of a cone, and the face that described elastic jacket matches with body tip boss is taper seat.
Preferably, the central axis of axle and the central axis of body coincide.
Preferably, the end face of centring ring is provided with taper seat chamfering.
Workpiece loading and unloading of the present invention is easy, clamping, and location is reliable, it is ensured that Workpiece Machining Accuracy, for various sizes of workpiece, only need to change elastic jacket, just can realize the clamping of different workpieces, and interchangeability is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of centring type elasticity internal expanding fixture.
Accompanying drawing labelling: 1-transition disc, 2-hex screw, 3-compacting ring, 4-body, 5-centring ring, 6-axle, 7-spring collar, 8-draws pin, 9-elastic jacket.
Detailed description of the invention
Centring type elasticity internal expanding fixture of the present invention, including body 4, described body 4 is stepped boss, end boss is socketed with an elastic jacket 9, described elastic jacket 9 can slide on body 4 and be connected with the axle 6 of 4 centers that are arranged on body by drawing pin 8, and outside elastic jacket 9, it is socketed with spring collar 7, boss adjacent with elastic jacket 9 on described body 4 is socketed with centring ring 5, also being socketed with a compacting ring 3 on this boss, described compacting ring 3 is connected with the transition disc 1 being socketed in body 4 head end boss by hex screw 2. Body 4 end boss is a frustum of a cone, and the face that described elastic jacket 9 matches with body 4 end boss is taper seat. The central axis of the central axis of axle 6 and body 4 coincides. The end face of centring ring 5 is provided with taper seat chamfering.
Elastic jacket 9 is enclosed within body 4, can slide on body 4 and by drawing pin 8 to be connected with axle 6, elastic jacket 9 is made to have a range of activity on body 4, workpiece can be driven after swelling workpiece to continue to be moved to the left, when the interior shape inclined-plane of workpiece and the conical surface of centring ring 5 fully in contact with time, workpiece is no longer moved to the left, thus realizing the purpose of location and clamping. during work, workpiece is contained on fixture, starting air valve makes piston driving axle 6 be moved to the left, axle 6 is by drawing pin 8 to drive elastic jacket 9 to be moved to the left, when elastic jacket 9 conical surface and body 4 taper-face contact, radially expand under the ramp effect of body 4, swelling workpiece, when axle 6 continues to be moved to the left, drive workpiece is moved to the left by elastic jacket 9 together, until the big end inclined-plane of workpiece and positioning sleeve 5 conical surface fully in contact with, workpiece no longer moves, the swelling of elastic jacket 9 is consistent with shape conical surface orientation in workpiece with moving direction, location and the purpose of clamping can be realized, after being finished down angle, making piston driving axle move right by reversal valve, axle 6 is by drawing pin 8 to drive elastic jacket 9 to move right, and elastic jacket 9 drives workpiece to move right, and when the inclined-plane of elastic jacket 9 disengages with the inclined-plane on body, unclamps workpiece. as can be seen here, the centering of this structure is reliable, need not enforce, both alleviate labor intensity, can eliminate again the error produced because clamping is not in place during clamping workpiece.
