Description

Numerical control lathe who contains cutter safety cover

Technical Field

The utility model relates to a digit control machine tool field, in particular to numerical control lathe who contains cutter safety cover.

Background

The numerically controlled lathe is one of the widely used numerically controlled machines at present. The cutting tool is mainly used for cutting and processing inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces with any taper angles, complex rotary inner and outer curved surfaces, cylindrical threads, conical threads and the like, can perform grooving, drilling, reaming, boring and the like, and can be used on a numerical control lathe.

The cutter structure comprises a cutter head and a cutter handle, as shown in fig. 1 and fig. 2, fig. 1 is a cutter commonly used in the prior art for machining a large workpiece, the cutter head of the cutter is connected to the cutter handle, the workpiece is machined under the control of a numerical control lathe, fig. 2 is another type of cutter, the cutter head of the cutter can be retracted into a protective cover, and unnecessary abrasion of the cutter head is avoided.

The improvement of the cutter shown in the figure 1 in the prior art is various, and because the abrasion of the cutter head is serious, the cutter head and the cutter handle connecting mechanism are designed in the prior art, so that the cutter head and the cutter handle are convenient to replace when abraded, but the overall idea is to replace an abrasion device, but the problem of the abrasion of the cutter cannot be solved.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to solve the problem of the prior art, the utility model provides a numerical control lathe who contains cutter safety cover, this numerical control lathe is provided with the safety cover between tool bit and handle of a knife for the cutter has reduced the wearing and tearing of handle of a knife part when using.

The technical scheme is as follows: the utility model relates to a numerical control lathe with a cutter protection cover, which comprises a main body, a cutter handle connected with the main body and a cutter head connected with the cutter handle, and is characterized in that the protection cover is sleeved on the periphery of the cutter handle; the middle of the protective cover is provided with a through hole through which the knife handle penetrates, and the protective cover comprises a cover body and an outer cover edge, wherein the cover body is perpendicular to the knife handle, and the outer cover edge extends towards the direction close to the knife head along the edge of the cover body.

Preferably, the outer edge of the cover body gradually increases in diameter from the first end to the second end of the outer edge.

Preferably, a protective sleeve is arranged between the through hole and the knife handle.

Preferably, the outer edge of both ends of protective sheath outwards extends horizontally respectively and forms two engaging lugs, and two engaging lugs block in through-hole both sides.

The thickness of the pipe wall of the protective sleeve is 5-8 mm.

Has the advantages that: (1) the utility model arranges the protective cover between the tool bit and the tool handle, thereby avoiding the abrasion of the tool handle part; (2) the protective cover of the utility model is provided with the outer edge of the cover body, so that the metal filings splashed when a workpiece is processed do not wear the knife handle; (3) the utility model discloses be provided with the protective sheath in handle of a knife and safety cover junction, avoid cutter and safety cover junction wearing and tearing.
