Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
A jig for a machine tool, comprising:
a base plate 100 having a square shape;
four peripheral clamping assemblies comprising a clamping plate 210, a first spring 220, a screw 230, and a collet 240; the clamping plate is hinged with one edge of the bottom plate; one end of the first spring is fixed on the clamping plate, and the other end of the first spring is fixed on the bottom plate; the screw rod penetrates through the clamping plate and is in threaded connection with the clamping plate; the clamping head is fixed at one end of the screw rod close to the bottom plate; and
a workpiece placing unit fixed at the center of the base plate; the workpiece placing unit comprises a cylinder 310 and a clamping unit; the clamping unit comprises a central disc 321 and at least three circumferentially distributed bearing clamping blocks 322; the lower end face of the central disc is fixedly connected with the upper end face of the cylinder; the receiving and clamping block is provided with an arc-shaped clamping surface 3221 and an inclined receiving surface 3222; the receiving and holding block is fixedly connected with the side surface of the central disc through a second spring 323.
In one embodiment, the number of the first springs is two.
In one embodiment, the number of circumferentially distributed capture blocks is 4.
In one embodiment, the said catch blocks are evenly circumferentially distributed.
In one embodiment, a rubber pad (not shown) is provided on the collet. The rubber pad is arranged on the chuck, so that the chuck cannot damage a clamped workpiece.
In one embodiment, an adjusting head 231 is provided at an end of the screw remote from the chuck.
