Abstract
The tool clamping device of the utility model belongs to a fastening device, which is composed of a chuck, claws, a spring coil, a force transmitting pin, a sleeve and a cover. The upper half part of the chuck is an external threaded cylindrical shape. A square hole is arranged in the central location of the chuck. The four claws are disposed in the inside the square hole of the centre chuck part, and the spring coil is disposed in the inside of the square opening formed from the four claws. The upper half part of the sleeve is a thread hole linked to the threaded part of the chuck. The lower half part of the sleeve is a cam face in contact with one end of the force transmitting pin in which the other end is in contact with one of the claws. The cover is linked to the chuck through the screw, so that the four claws can be remained inside the square hole of the chuck. The utility model has the advantages of rational design, simple structure, strong applicability, convenient device disassembly and fast clipping speed.
Description
Technical field
The utility model belongs to fastener, particularly a kind of tool holding device.
Background technology
Existing tool holding device is by the screw on the rotary clamp, four pushing blocks is moved forward, and makes by four that pushing block surrounded that central square holes enlarge or dwindle, with the shank position, instrument side of clamping different size.This anchor clamps applicability is strong, economical with materials, but need frequent rotating screw in the clamping tool process, cause loading and unloading and change that implementing procedure is loaded down with trivial details, labour intensity is big.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, a kind of tool holding device that provides a kind of square hole size adjusting speed to be exceedingly fast.
Tool holding device of the present utility model is made up of collet body, jaw, turn, power transmission pin, sleeve and cover plate.Collet body the first half outside cylinder is shaped on screw thread, and the collet body central part has a square hole, and four jaws are placed in collet body central authorities square hole inside, and turn is placed in the square opening inside that four jaws form.Rely on its elastic force to make four square holes that jaw surrounded be in maximum position, the first half of sleeve is a screwed hole, and it is connected with the threaded portion of collet body; The Lower Half of sleeve is the cam type face, and it contacts with an end of power transmission pin; And the other end of power transmission pin contacts with one of them jaw.Rotational sleeve, be that cam type face on the sleeve also rotates around the bush whorl axially bored line, cam type surface and power transmission pin join the contact sleeve to the distance of screwed hole axis by greatly to little variation, then cam type surface pushes the power transmission pin, thereby the power transmission pin promotes first jaw to move forward, first jaw promotes second jaw reach again, and second jaw promotes the 3rd jaw reach again, and the 3rd jaw promotes the 4th jaw reach again.The square hole that four jaws are surrounded dwindles.Cover plate links together by screw and collet body, makes four jaws remain in the square hole of collet body.
A kind of tool holding device of the present utility model is reasonable in design, simple in structure, applicability is strong, dismantling device is convenient, and clamping speed is fast.

Fig. 3 be a kind of tool holding device B-B of the present utility model to cutaway view.
The specific embodiment
A kind of tool holding device of the present utility model is made up of collet body 1, jaw 2, turn 3, power transmission pin 4, sleeve 5, cover plate 6 and screw 7.Four jaws 2 are placed on square hole 8 inside of collet body 1, turn 2 places in four jaws, the 2 formed square openings 9, the screwed hole 10 of sleeve 5 is connected with the screw thread of collet body 1, and sleeve 5 eccentric circular holes 11 contact with an end 12 of power transmission pin 4, and power transmission pin 4 other ends contact with jaw 2.Rotational sleeve 5, be eccentric circular hole 11 contact with power transmission pin 4, to sleeve 5 screwed holes 10 axial line distance by greatly to little variation, then eccentric circular hole 11 pushing power transmission pins 4, move forward thereby power transmission pin 4 promotes jaws 2, thereby four jaws are passed in turn, the square hole 14 that is surrounded is dwindled; Backward rotation sleeve 5, then turn 3 enlarges square hole 14, and cover plate 6 links together by screw 7 and collet body 1, makes four jaws 2 remain on collet body 1 square hole 8 inside.On jaw 2, have groove 13, to avoid and 4 collisions of power transmission pin.
