To the defect among the prior art, the utility model provides an automatic adjust work piece position and can be applicable to the anchor clamps subassembly of long axis type work piece processing.

The utility model provides an anchor clamps subassembly for processing hardware component, includes sleeve, top, cylinder, bearing, nut and sharp slip table, the sleeve with the slider fixed connection of sharp slip table, it is located to top in the telescopic hole, it is top including sharp portion and T type axial region, top T type axial region with the inner circle fixed connection of bearing, bearing fixed connection be in on the telescopic right-hand member face, the nut with top T type axial region threaded connection, telescopic outer peripheral face is equipped with the through-hole, the through-hole with telescopic hole intercommunication, the cylinder is fixed on the telescopic outer peripheral face, the piston rod of cylinder with the through-hole constitutes the sliding pair, top point portion is located the right side below of cylinder.

Preferably, a piston rod of the cylinder is fixedly connected with a pressing block.

Preferably, the motor of the linear sliding table is provided with a self-locking device.

Preferably, the cylinder is a stroke-adjustable cylinder.

Preferably, the bearing support is arranged at the right end of the sleeve, and the bearing is fixed at the right end of the sleeve through the bearing support.

The beneficial effects of the utility model are embodied in: through the structure, before a workpiece is machined, one end of the workpiece is clamped and fixed through the chuck of the numerical control machine tool in the prior art, the other end of the workpiece enters the inner hole of the sleeve and is matched with the tip, and then cutting machining is carried out through the cutter in the prior art. When the length of the workpiece exposed out of the numerical control machine tool chuck is to be adjusted, the cylinder stretches out the piston rod to prop against the workpiece, the numerical control machine tool control chuck loosens the workpiece, the linear sliding table drives the sleeve to move backwards, the workpiece is pulled to move a specified position to stop, the numerical control machine tool control chuck clamps and fixes the workpiece, and the piston rod of the cylinder resets to continue processing. Compared with the prior art, the tool center can be installed, the position of the workpiece can be automatically adjusted, and the tool center can be suitable for machining long-shaft workpieces.

Throughout the drawings, like elements or portions are generally identified by like reference numerals. In the drawings, elements or portions are not necessarily drawn to scale.

FIG. 1 is a schematic structural view of the present invention applied to the machining of a numerically controlled machine tool;

fig. 2 is a sectional view of the structure of the sleeve, the center, the bearing, the nut, the cylinder and the pressing block of the present invention.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

Fig. 1 to 2 show, a clamp assembly for processing hardware component, including sleeve 1, top 2, cylinder 3, bearing 4, nut 5 and straight line slip table 6, sleeve 1 with the slider 61 fixed connection of straight line slip table, top 2 is located in the hole of sleeve 1, top 2 includes sharp portion 21 and T type axial region 22, top T type axial region 22 with the inner circle fixed connection of bearing 4, bearing 4 fixed connection is in on the right-hand member face of sleeve 1, nut 5 with top T type axial region 22 threaded connection, the outer peripheral face of sleeve 1 is equipped with through-hole 11, through-hole 11 with the hole intercommunication of sleeve 1, cylinder 3 is fixed on the outer peripheral face of sleeve 1, the piston rod of cylinder 3 with through-hole 11 constitutes the sliding pair, top point portion 21 of top is located the right side below of cylinder 3, a piston rod of the cylinder 3 is fixedly connected with a press block 31.
