Abstract
A self-centering sleeve head comprises a sleeve body. A radial slide groove is formed in the sleeve body. A left clamping block and a right clamping block are arranged in the slide groove and can slide leftwards and rightwards along the slide groove. A two-way threaded rod is connected between the left clamping block and the right clamping block. The left clamping block and the right clamping block are connected with the two-way threaded rod through threads. Fixing sleeves are arranged at the two ends of the two-way threaded rod. The fixing sleeves and the two-way threaded rod are fixedly connected through limiting pins. The self-centering sleeve head can be suitable for detaching and installing bolts of various different specifications and sizes and nuts of various different specifications and sizes and can replace an existing sleeve head. The manufacturing cost of a sleeve spanner is reduced, and the self-centering sleeve head is convenient to carry.
Description
Technical field
The present invention relates to machine tool technical field, particularly a kind of self-centering sleeve being applicable to various different size bolt, nut dismounting.
Background technology
The instrument that box spanner is mechanical erection or often uses in dismantling, box spanner not only torsional moment is large, and tactical diameter is little, and by lengthening torque arm, work moment during increase installation or removal, therefore, is used widely in all kinds of production practices.But, box spanner often needs the collet head being equipped with various different size, and sleeve can only match the nut (box spanner commercially buying a set of M6 ~ M20 often needs outfit 7 ~ 9 collet heads) of a dismounting dimensions, and existing collet head is for the hex nut of some special requirements and sides nut head, because of collet head for fixing specification is then often helpless, simultaneously, increasing of collet head must cause the problems such as kit carries inconvenience, and manufacturing cost is higher.
Summary of the invention
The invention solves above technical problem, provide a kind of structure simple, low cost of manufacture, the self-centering collet head that applicability is strong.
For solving the problems of the technologies described above, present invention employs a kind of self-centering collet head, comprise sleeve body, described sleeve body is provided with radial chute, left fixture block and right fixture block is provided with in described chute, described left fixture block and right fixture block can horizontally slip along chute, reverse-flighted screw is connected with between described left fixture block and right fixture block, described left fixture block and being threaded connection between right fixture block and reverse-flighted screw, described reverse-flighted screw two ends are respectively arranged with fixed cover, and described fixed cover is fixedly connected with by spacer pin with between reverse-flighted screw.
As preferred further to the present invention, described sleeve body be provided with clamp nut, be threaded connection between described clamp nut and sleeve body.
Further, sleeve body described in the present invention is provided with square knuckle.
The beneficial effect that the present invention has: collet head is under the effect of reverse-flighted screw, and left and right slide block can realize free-extension, thus be applicable to various different size, the dismounting of screw bolt and nut of size and installation; Meanwhile, adopt such collet head can replace original a set of collet head, both reduced the manufacturing cost of box spanner, and be convenient for carrying again, can be widely used in field assembling and various maintenance activity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, sleeve body; 2, left fixture block; 3, right fixture block; 4, reverse-flighted screw; 5, fixed cover; 6, spacer pin; 7, clamp nut; 8, chute; 9, square knuckle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1, for a kind of self-centering collet head, comprise sleeve body 1, sleeve body 1 is provided with radial chute 8, be provided with left fixture block 2 and right fixture block 3 in chute 8, left fixture block 2 and right fixture block 3 can horizontally slip along chute 8, reverse-flighted screw 4 is connected with between left fixture block 2 and right fixture block 3, left fixture block 2 and being threaded connection between right fixture block 3 and reverse-flighted screw 4, reverse-flighted screw 4 two ends are respectively arranged with fixed cover 5, are fixedly connected with between fixed cover 5 with reverse-flighted screw 4 by spacer pin 6.
In the present invention, described sleeve body 1 is provided with clamp nut 7, is threaded connection between described clamp nut 7 and sleeve body 1.
In the present invention, described sleeve body 1 is provided with square knuckle 9.
When using the nut on degree of tightness machine of the present invention, as long as left and right fixture block is enclosed within nut, rotate reverse-flighted screw 4, make left fixture block 2 and right fixture block 3 under the effect of reverse-flighted screw 4, move to center position, realize self-centering and binding nut, then torque arm is enclosed within the square knuckle 9 above sleeve body 1, and rotate torque arm, can tightening nut like a cork.
