Abstract

The utility model relates to a drill bit anchor clamps, include chuck body and edge the ejector pin that chuck body axis direction set up, the ejector pin is connected to actuating mechanism through the hydro-cylinder pull rod, the awl core is installed to the tip one side of chuck body, the ejector pin passes the awl core, the outside end of awl core is equipped with the conical surface with drill bit work piece taper hole matched with. The utility model provides a drill bit anchor clamps, the taper hole of the ejector pin top clamp drill bit along the axis direction of chuck, compare with traditional limit top, this application adopts central top simple structure, and the ejector pin top presss from both sides the stroke of drill bit and shortens, improves work efficiency; the cylinder is adopted to push the ejector rod, so that the unloading is realized, the hammering unloading for manpower is replaced, the labor intensity of workers is reduced, and the surface quality of a workpiece is improved; on the other hand, under the condition that the appearance of the chuck body is not changed, the taper heads of various taper holes can be machined by replacing the taper cores with different tapers, and the chuck is high in universality and simple in structure.

Description

Drill bit clamp

Technical Field

The utility model relates to an anchor clamps technical field especially relates to a bore bit anchor clamps.

Background

The drill bit is a drilling tool widely applied to various projects, in the processing and production process of the drill bit, the outer circle turning of the working end face of the drill bit is often involved, different fixtures are required to be used for clamping the drill bit, the fixtures can directly influence the processing efficiency, a positioning conical plug structure is generally adopted at present, the rationality of the positioning conical plug structure is a key factor for determining the processing efficiency, and the existing positioning conical plug is large in stroke and low in working efficiency due to the fact that the ejector rod is jacked from the edge of the drill bit.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned not enough of prior art, the utility model provides a bore bit anchor clamps solves the structure complicacy that current bore bit anchor clamps exist, technical problem that work efficiency is low.

The utility model discloses a realize through following technical scheme:

a drill bit clamp comprises a chuck body and an ejector rod arranged along the axis direction of the chuck body, wherein the ejector rod is connected to a driving mechanism through a cylinder pull rod, a conical core is installed on one side of the small end of the chuck body, the ejector rod penetrates through the conical core, and a conical surface matched with a conical hole of a drill bit workpiece is arranged at the outer side end of the conical core.

Furthermore, the oil cylinder pull rod is positioned in a groove of the chuck body.

Further, one side of the large end of the chuck body is connected to a driving mechanism through a transition disc.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the utility model provides a drill bit anchor clamps, ejector pin press from both sides the drill bit taper hole along the axis direction of chuck, compare in traditional limit top, this application adopts central top simple structure, and the ejector pin pushes up the stroke that presss from both sides the drill bit and shortens, improves work efficiency; the cylinder is adopted to push the ejector rod, so that actual unloading is realized, hammering unloading by manpower is replaced, the labor intensity of workers is reduced, and the surface quality of a workpiece is improved; on the other hand, under the condition that the appearance of the chuck body is not changed, the taper heads of various taper holes can be machined by replacing the taper cores with different tapers, and the chuck is high in universality and simple in structure.

Drawings

Fig. 1 is a schematic structural view of a drill bit clamp according to an embodiment of the present invention.

In the figure:

1. a transition disk; 2. a chuck body; 3. a cylinder pull rod; 4. a conical core; 5. a top rod; 6. and (5) bit workpieces.

Detailed Description

The following examples are presented to illustrate certain embodiments of the invention and should not be construed as limiting the scope of the invention. The present disclosure may be modified from materials, methods, and reaction conditions at the same time, and all such modifications are intended to be within the spirit and scope of the present invention.

In the existing positioning conical plug structure, the ejector rod 5 is arranged in the direction parallel to the axis of the chuck body 2 (not coincident with the axis), the driving mechanism drives the ejector rod 5 to move forwards to abut against the side edge part of the conical hole of the drill bit workpiece 6, the conical core 4 extends into the conical hole of the drill bit workpiece 6, the movement stroke of the ejector rod 5 is large, and the working efficiency is low.

The drill bit clamp comprises a chuck body 2 and an ejector rod 5 arranged along the axial direction of the chuck body 2, wherein the ejector rod 5 is connected to a driving mechanism through an oil cylinder pull rod 3, the oil cylinder pull rod 3 is positioned in a groove of the chuck body 2, one side of the large end of the chuck body 2 is connected to the driving mechanism through a transition disc 1, one side of the small end of the chuck body 2 is provided with a conical core 4, and the conical cores 4 with different tapers are replaced according to the size of the conical holes of a drill bit workpiece 6 on the premise of not changing the appearance of the chuck body, so that the drill bit clamp is simple in structure and high in universality; the ejector rod 5 penetrates through the conical core 4, and the outer side end of the conical core 4 is provided with a conical surface matched with the conical hole of the drill bit workpiece 6, so that clamping is conveniently realized.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
