The aim of the invention can be achieved by the following technical scheme: the chuck structure is characterized in that the chuck structure is a cylindrical body, one end of the body is opened, a hollow sleeve is arranged in the body, the circumferential surface of the sleeve is connected with the middle of the inner wall of the body in a threaded manner, a spiral groove is formed in the end face, close to one end of the opening, of the sleeve, a plurality of guide blocks are uniformly arranged on the end face, close to one end of the opening, of the body in the circumferential direction, a caliper is connected onto the guide blocks in a sliding manner in the radial direction of the body, a plurality of threaded ribs corresponding to the spiral groove are arranged on the caliper, a step hole is formed in one end, close to the bottom of the body, of the sleeve, a pressing block is connected with an inner thread of the step hole, a plurality of guide rods located at the eccentric position of the pressing block are fixedly arranged on the pressing block, and a guide hole corresponding to the guide rods is formed in the bottom of the body.
The axial workpiece is directly inserted from one end of the opening of the body, the pressing plate is pressed to translate to the bottom of the body, the sleeve is driven to rotate, and in the process of sleeve rotation, under the interaction of the spiral grooves and the thread ribs on the calipers, the calipers move along the axial direction of the body, the calipers synchronously move, the axial workpiece is clamped, the end part of the axial workpiece is well straightened, in the whole process, the axial workpiece does not need other tools or manual operation, only the axial workpiece is directly inserted, the efficiency is extremely high, the clamping is reliable, in the process that the axial workpiece is processed, the clamping strength of the calipers to the axial workpiece is only further increased due to the action of the axial external force, and the situation of looseness does not exist.
In the chuck structure for rapidly clamping the shaft workpiece, a reset spring is connected between the pressing block and the bottom of the body.
After the shaft workpiece is taken out, the reset spring can reset the pressing plate, so that the calipers move outwards and recover the state before clamping again.
In the chuck structure for rapidly clamping the shaft workpiece, a plurality of mutually avoiding grooves are formed in the bottom of the body, and a plurality of positioning holes corresponding to the avoiding grooves are uniformly formed in the circumferential direction of the end face, close to the bottom of the body, of the sleeve.
In order to be able to dismantle the work piece fast, set up and dodge groove and locating hole, insert through the spanner and dodge the inslot to insert in the locating hole, because the locating hole is in the eccentric position department of body, pull sleeve counter-rotating can loosen the centre gripping of calliper to the work piece.
In the chuck structure for rapidly clamping the shaft workpiece, the thread lead angle of the thread on the circumferential surface of the pressing block is larger than that of the thread on the circumferential surface of the sleeve.
The large threads drive the small threads, so that the workpiece can sensitively drive the pressing plate to move during insertion, and the sleeve is rotated.

In the figure, 1, a body; 2. a sleeve; 3. a spiral groove; 4. a guide block; 5. a caliper; 6. briquetting; 7. a guide rod; 8. a return spring; 9. an avoidance groove; 10. and positioning holes.
Detailed Description
The following are specific embodiments of the present invention and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, this chuck structure tube-shape body 1, the one end opening of body 1 is provided with a hollow sleeve 2 in the body 1, threaded connection in the middle of the peripheral surface of sleeve 2 and the body 1 inner wall, the sleeve 2 is close to the terminal surface of body 1 opening one end on have helical groove 3, circumference evenly is provided with a plurality of guide blocks 4 on the terminal surface that body 1 is close to opening one end, radial sliding connection along body 1 has a calliper 5 on the guide block 4, a plurality of thread protruding muscle that have on the calliper 5 correspond with helical groove 3, the sleeve 2 is close to the one end of body 1 bottom has a step hole, step hole internal thread connection has a briquetting 6, fixedly on the briquetting 6 be provided with a plurality of guide bars 7 that are located briquetting 6 eccentric position department, the guiding hole that corresponds with guide bar 7 has been seted up to the bottom of body 1.
The axial workpiece is directly inserted from one end of the opening of the body 1, the pressing plate is pressed and translates to the bottom of the body 1, the sleeve 2 is driven to rotate, the sleeve 2 rotates, the calipers 5 move along the axial direction of the body 1 under the interaction of the spiral grooves 3 and the thread ribs on the calipers 5, the calipers 5 synchronously move, the axial workpiece is clamped, the end part of the axial workpiece is well straightened, the axial workpiece does not need other tools or manual operation in the whole process, the axial workpiece is only required to be directly inserted, the efficiency is extremely high, the clamping is reliable, the clamping strength of the calipers 5 to the axial workpiece is only further increased under the action of the axial external force in the machining process of the axial workpiece, the loosening condition does not exist, and the axial workpiece is characterized in that the firmness and the coaxiality are extremely high when the axial workpiece is subjected to the perforating operation in the axial direction.
A reset spring 8 is connected between the pressing block 6 and the bottom of the body 1. After the shaft workpiece is taken out, the return spring 8 can reset the pressing plate, so that the caliper 5 moves outwards and the state before clamping again is restored.
