The utility model provides a technical scheme is: the utility model provides a special jack catch of hydro-cylinder turning, includes: the clamping device comprises a bed body, a chuck, a clamping jaw and a workpiece, wherein the chuck is fixed on the bed body and can rotate on the bed body, the clamping jaw is arranged on the chuck, the clamping jaw can slide on the chuck, and the position of the clamping jaw is fixed through sliding.

Preferably, the jaws slide on the chuck through a plurality of slideways pointing to the center of the chuck on the chuck.

Further preferably, the contact surface of the claw and the workpiece is stepped, and the contact surface is a rough surface.

Further preferably, the center of the chuck is fixedly provided with a bolt, a positioning disc is placed on the bolt, the center of the positioning disc is provided with a threaded round hole, and the positioning disc can rotate to the bolt.

The utility model provides a pair of special jack catch of hydro-cylinder turning, this jack catch mainly include the bed body, chuck, jack catch and work piece, and in order to adapt to the numerical control processing work piece that does not use the bore, the jack catch slides and sets up on the chuck, and position through the adjustment jack catch is fixed, can cooperate with not unidimensional work piece.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model has the advantages of simple structure and reasonable design, convenient to use designs the jack catch into the echelonment, adopts wide contact terminal surface simultaneously, has effectively solved when cylinder turning terminal surface and screw thread, and outer cylinder axial string moves, and the effectual processing deviation that has controlled has saved the process time that the jack catch was changed to the secondary.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: the device comprises a bed body 1, a chuck 2, a jaw 3, a workpiece 4, a bolt 5 and a positioning disc 6.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the utility model provides a special jack catch of hydro-cylinder turning, include: the lathe comprises a lathe body 1, a chuck 2, a clamping jaw 3 and a workpiece 4, wherein the chuck 2 is fixed on the lathe body 1 and can rotate on the lathe body 1, the clamping jaw 3 is arranged on the chuck 2, the clamping jaw 3 can slide on the chuck 2, the position of the clamping jaw 3 is fixed through sliding, when the workpiece 4 is machined, the workpiece 4 is placed on the chuck 2, the clamping jaw 3 slides, and the clamping jaw 3 is adjusted to enable the workpiece 4 to be tightly buckled on the inner wall of the workpiece 4.

As an improvement of the technical scheme, the jaws 3 slide on the chuck 2 through a plurality of slideways which point to the circle center of the chuck 2 and are arranged on the chuck 2, each slideway is internally provided with one jaw 3, the bottom of each jaw 3 is in a convex shape, the bottom of each jaw 3 is positioned inside the slideway, and the jaw part of each jaw 3 extends out of the slideway, so that the jaws 3 can slide in the slideway and cannot be separated from the chuck 2, in the using process, the chuck 2 axially rotates along the circle center, and the jaws can have the trend of outward movement on the slideway due to centrifugal force in the rotating process, so that the stability of the jaws 3 can be ensured under the condition of high-speed rotation, and the phenomenon that the workpiece 4 is driven in the rotating process is avoided.

As the improvement of the technical scheme, the contact surface of the clamping jaw 3 and the workpiece 4 is in a step shape, the contact surface is a rough surface, the step-shaped clamping jaw 3 is longer and wider than a traditional clamping jaw, the contact area of the clamping jaw 3 and the inner wall of the workpiece 4 is larger, the clamping force of the claw tip of the clamping jaw 3 on the workpiece 4 can be larger by adopting the step-shaped clamping jaw 3, the stability of the workpiece 4 in high-speed rotation can be more effectively ensured, in addition, the rough surface is arranged at the contact position of the clamping jaw 3 and the workpiece 4, the friction force between the clamping jaw 3 and the workpiece 4 is increased, and the stability of the workpiece 4 in high-speed rotation can be favorably improved.

As the improvement of the technical scheme, a bolt 5 is fixedly arranged at the center of the chuck 2, a positioning disc 6 is placed on the bolt 5, a threaded round hole is formed in the center of the positioning disc 6, the positioning disc 6 can rotate to the bolt 5, when the clamping jaw 3 fastens the workpiece 4, the positioning disc 6 is placed at the center of the chuck 2, the clamping jaw 3 is positioned at the current position, the clamping jaw 3 cannot slide to the center of the chuck 2 through a slide way, and the stability of the clamping jaw 3 in high-speed rotation is further improved.

Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
