Abstract
The utility model discloses a machine tool elastic chuck. A body is installed on a chuck base of a machine tool, the body comprises a fixing end portion, a fixing neck portion and a fixing head portion, the body is axially provided with at least two through clamping notches, the clamping notches are located in the fixing neck portion and the fixing head portion, a clamping hole for clamping a workpiece is formed in the body, and the clamping hole is provided with a workpiece clamping face, a positioning face and an auxiliary clamping inner conical face from inside to outside along an axis; the fixing head portion is of a fusiform shape with an expanded middle portion. The workpiece is placed into the elastic chuck, a machine tool pull rod is operated to clamp the fixing neck portion and the fixing head portion, the clamping notches are further tightly clamped to be forced to be closed, and the workpiece clamping face can be tightly attached to the surface of the workpiece to achieve clamping. Due to the fact that the fixing head portion is of the fusiform shape with the expanded middle portion and can clamp in the axial direction and the radial direction, disengagement of the elastic chuck and vibration when the elastic chuck is machined are avoided..
Description
Technical field
The utility model relates to a kind of lathe collet, belongs 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 the lathe, carry out the processing of workpiece again by corresponding process tool.At present, because the restriction of collet structure causes the part that overhangs of work piece long easily, adding man-hour, shaking easily, causing the displacement of machined surface, causing mismachining tolerance to increase, percent defective improves.
The utility model content
The utility model is intended to provide a kind of lathe collet, has good good clamping effect, reduces the length of the overhang of workpiece, avoids workpiece because the long machining accuracy that causes of overhang does not reach requirement.
The purpose of this utility model can reach by following measure: 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 the 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 is followed successively by workpiece clamping area, locating surface and the auxiliary inner conical surface that clamps from inside to outside along axis; Described fixing head is middle fusiformis of expanding.
The technique scheme difference with the prior art is: at first, this collet is installed on the 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 and force clamping notch closure, make workpiece clamping area and surface of the work fit tightly and realize clamping.Because the fusiformis of expanding in the middle of fixing head is set to can be avoided the vibration of deviating from and add man-hour of collet axially and radially clamping.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 evenly stressed when clamping.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model lathe collet embodiment.
The specific embodiment
A kind of lathe collet, as shown in Figure 1, the utility model lathe collet 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 the 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 is followed successively by workpiece clamping area 51, locating surface 52 and the auxiliary inner conical surface 53 that clamps from inside to outside along axis; Described fixing head 3 is middle fusiformis of expanding.
At first, this collet is installed on the 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 area and surface of the work fit tightly and realize clamping.Because the fusiformis of expanding in the middle of fixing head 3 is set to can be avoided the vibration of deviating from and add man-hour of collet axially and radially clamping.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 only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
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 the 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 is followed successively by workpiece clamping area, locating surface and the auxiliary inner conical surface that clamps from inside to outside along axis; Described fixing head is middle fusiformis of expanding.
