Abstract
The invention discloses a flexible chuck of a machine tool. A body is arranged on a chuck seat of the machine tool and comprises a fixed end, a fixed neck and a fixed head; at least two perforative clamping notches are formed on the body in the axial direction and positioned on the fixed neck and the fixed head; a clamping hole for clamping a workpiece is formed in the body and consists of a workpiece clamping surface, a positioning surface and an auxiliary clamping inner conical surface from inside to outside in sequence along the axis; and the fixed head has a shape of a shuttle with an expanded middle. The workpiece is placed into the flexible chuck, a pull rod of the machine tool is operated, the fixed neck and the fixed head are further clamped to close the clamping notches, and the workpiece clamping surface is tightly attached to the surface of the workpiece for clamping; and the fixed head has the shape of the shuttle with the expanded middle, so that the fixed head can be clamped in the axial direction and the radial direction, the flexible chuck is prevented from being separated, and vibration during machining is avoided.
Description
Technical field
The present invention relates to a kind of lathe collet, belong to the lathe special fixture.
Background technology
Among machining, often need work piece is gripped.During for the processing rod member, often need by chuck, workpiece one end to be wrapped up clamping, be fixed on lathe, then carry out the processing of workpiece by corresponding process tool.At present, due to the restriction of collet structure, easily cause the part that overhangs of work piece long, adding man-hour, easily shake, cause the displacement of machined surface, cause mismachining tolerance to increase, percent defective improves.
Summary of the invention
The invention is intended to provide a kind of lathe collet, have good good clamping effect, reduce the length of the overhang of workpiece, avoid workpiece because the long machining accuracy that causes of overhang does not reach requirement.
Purpose of the present invention can reach by following measures: a kind of lathe collet, body is installed on the base of the carrier head of lathe, described body comprises an anchor portion, fixedly neck and fixing head, be axially arranged with at least two clamping notches that run through on described body, described clamping notch is positioned at fixedly neck and fixing head, be provided with the clamping hole of holding workpiece in body, described clamping hole along axis from inside to outside successively by Workpiece clamping face, locating surface and auxiliary clamp inner conical surface; Described fixing head is middle fusiformis of expanding.
The technique scheme difference with the prior art is: at first, this collet is arranged on lathe, be connected with the lathe pull bar, workpiece is put into this collet, operation lathe pull bar, fixedly neck and fixing head clamp, and further clamp to force the clamping notch closed, make Workpiece clamping face and surface of the work fit tightly and realize clamping.Because fixing head is set to middle fusiformis of expanding, can at axial and radial clamping, avoid the vibration of deviating from and add man-hour of collet.Moreover the clamping notch is positioned at fixedly neck and fixing head, makes clamping hole holding workpiece fully, avoids the part that overhangs of workpiece long.
Further, described clamping notch arranges three, makes workpiece uniform stressed when clamping.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of lathe collet embodiment of the present invention.
The specific embodiment
A kind of lathe collet, as shown in Figure 1, lathe collet of the present invention is installed on the base of the carrier head of lathe.Body comprises an anchor portion 1, fixedly neck 2 and fixing head 3, be axially arranged with at least two clamping notches 4 that run through on described body, described clamping notch 4 is positioned at fixedly neck 2 and fixing head 3, be provided with the clamping hole 5 of holding workpiece in body, described clamping hole 5 along axis from inside to outside successively by Workpiece clamping face 51, locating surface 52 and auxiliary clamp inner conical surface 53; Described fixing head 3 is middle fusiformis of expanding.
At first, this collet is arranged on lathe, is connected with the lathe pull bar, workpiece is put into this collet, operation lathe pull bar, fixedly neck 2 and fixing head 3 clamp, further clamp and force clamping notch 4 closures, make Workpiece clamping face and surface of the work fit tightly and realize clamping.Because fixing head 3 is set to middle fusiformis of expanding, can at axial and radial clamping, avoid the vibration of deviating from and add man-hour of collet.Moreover clamping notch 4 is positioned at fixedly neck 2 and fixing head 3, makes clamping hole 5 holding workpiece fully, avoids the part that overhangs of workpiece long.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. lathe collet, body is installed on the base of the carrier head of lathe, described body comprises an anchor portion, fixedly neck and fixing head, be axially arranged with at least two clamping notches that run through on described body, described clamping notch is positioned at fixedly neck and fixing head, be provided with the clamping hole of holding workpiece in body, it is characterized in that: described clamping hole along axis from inside to outside successively by Workpiece clamping face, locating surface and auxiliary clamp inner conical surface; Described fixing head is middle fusiformis of expanding.
