Description

Rapid clamping device for processing outer circle of thin-walled tube

Technical Field

The utility model relates to a lathe processing specialized tool field specifically is a thin wall pipe excircle processing is with quick clamping device.

Background

Before the thin-wall pipe fitting is electroplated, the outer circle needs to be polished in advance, and for the thin-wall pipe fitting with the wall thickness smaller than 0.3mm, the pipe fitting needs to be clamped in advance during polishing, but due to the fact that the wall thickness is easy to deform, clamping of the thin-wall pipe fitting with the wall thickness smaller than 0.3mm is difficult to complete by a common machine tool, and even if clamping can be completed, the clamped part cannot be polished during polishing.

SUMMERY OF THE UTILITY MODEL

For solving above technical problem, the utility model provides a simple, practical, efficient thin wall pipe excircle processing is with quick clamping device.

The utility model discloses a following technical scheme realizes: the quick clamping device for processing the excircle of the thin-walled tube comprises an expansion head and a tip in a tailstock shaft taper hole, wherein the expansion head and the tip are installed on a chuck of a machine tool, the expansion head is made of polyurethane, a clamping table is arranged at the left end of the expansion head, a conical head with a taper is arranged at the right end of the expansion head, the taper of the conical head is 7 degrees, and the hardness value is Shore hardness 80.

The centre is a rotary elastic centre.

The utility model discloses simple structure, the course of working is safe convenient, and work efficiency is high, and application scope is wide, not only is applicable to the polishing of thin wall pipe excircle, still is applicable to the surface machining of other types of pipe fitting.

Detailed Description

As shown in fig. 1 and 2, the rapid clamping device for processing the excircle of the thin-walled tube comprises an expansion head 1 and a tip 2, wherein the expansion head 1 is made of polyurethane, the left end of the expansion head is provided with a clamping table 10, and the right end of the expansion head is provided with a conical head 11 with a taper. The polyurethane expansion head 1 is arranged on a chuck 4 of a machine tool through a clamping table 10, and the tip 2 is arranged in a shaft taper hole 5 of a tailstock of the machine tool. Two ends of the thin-walled tube 3 to be polished are respectively sleeved on the conical head 11 and the tip 2.

If the taper of conical head 11 is too big, the tight power of expanding is not enough, and the work piece skids easily, if the undersize, the tight power of expanding is enough, and it is just very difficult to get the piece, influences work efficiency, and the effect is best when the conical head 11 tapering is 7 degrees through the experiment.

The expansion head 1 is made of polyurethane material so as to increase the contact area and the friction force during expansion, and the hardness value is Shore 80. The hardness is too high, the contact area is small, the friction coefficient is insufficient, and the workpiece is easy to slip. The hardness is too low, the friction coefficient is enough, but when the workpiece rotates at a high speed, the workpiece is positioned at a poor position, the jumping quantity is too large, the polishing effect is influenced, and safety risks exist, and experiments prove that the hardness value is most appropriate to be 80 Shore hardness.

The centre 2 is a rotary elastic centre, which not only ensures the normal rotation of the workpiece, but also ensures the expansion of the workpiece.

The utility model relates to a thin wall pipe excircle processing is with quick clamping device, will expand earlier when using and tighten head 1 and top 2 clamping on the lathe, then will treat 3 pot heads of polishing thin wall pipe on the conical head 11 that expands and tighten head 1, the other end is tight with top 2 top, can carry out thin wall pipe's excircle polishing work. After the polishing work is finished, the center 2 is moved away, the pipe fitting is taken down, the whole machining process is safe and convenient, and the working efficiency is high. The utility model discloses not only be applicable to the polishing of thin wall pipe excircle, still be applicable to the surface machining of other types of pipe fittings.
