Abstract

The utility model discloses a multifunctional combined turning cutter, which comprises a cutter rest, a cutter handle and two cutting heads arranged on the cutter rest. The cutter rest and the cutter handle are integrated in inserting mode through a frustum arranged on the cutter rest and a taper hole arranged at the end portion of the cutter handle and are fixed through a connection mechanism. The two cutting heads arranged on the cutter rest are respectively arranged above and below the cutter rest. The multifunctional combined turning cutter has the advantages that the two cutting heads are respectively arranged above and below the cutter rest, the cutter rest has two cutting heads, when one hard alloy cutting head is abraded or damaged, the other hard alloy cutting head can continuous to cut, utilization rate of the cutter rest is greatly improved, time for replacing the cutter rest is saved, and working efficiency is improved. A cutter body is arranged on a lateral wall at the rear end of the cutter handle so that utilization rate of the carbon steel cutter handle is further improved.

Description

Multi-functional combination lathe tool

Technical field

The utility model relates to the lathe grinding instrument, especially relates to multi-functional combination lathe tool.

Background technology

Mostly present brazed carbide turning tool is single cutting edge of a knife or a sword cutter, detains lathe tool etc. like 90 ° of lathe tools, 45 ° of lathe tools, accent.But their structure all is carbon steel tool rest and the handle of a knife by integrative-structure to be constituted, and on tool rest, with scolder carbide bit is welded on tool rest, and by using behind the selected geometric parameter sharpening.And mostly the reason of scrapping of brazed carbide turning tool is owing to the carbide bit wearing and tearing or damages institute to cause, and this just causes a large amount of wastes of carbon steel tool rest and handle of a knife.China's utility model patent discloses a kind of " Combination Welding lathe tool " (patent No.: ZL201120003306.4), solved the problems referred to above well, but also had weak point, as when carbide bit wearing and tearing or damage, still need change the carbon steel tool rest.

Summary of the invention

The utility model purpose is to provide a kind of multi-functional combination lathe tool that improves carbon steel tool rest utilization rate.

For realizing above-mentioned purpose, the utility model is taked following technical proposals:

The described multi-functional combination lathe tool of the utility model, it comprises tool rest, handle of a knife and is arranged on the cutter tip on the said tool rest; Said tool rest and handle of a knife are one through the frustum that is arranged on the tool rest with the taper hole plug-in mounting that is opened in the handle of a knife end, and fix through bindiny mechanism; The cutter tip that is arranged on the tool rest is two, be separately positioned on the top of tool rest with below.

Said bindiny mechanism is the connecting screw rod that is arranged in the handle of a knife through hole, an end of said connecting screw rod be opened in the screw bolt on the said frustum, the other end extends outside the handle of a knife and the nut bolt.

Said tool rest is 90 ° of tool rests or 45 ° of tool rests.

The rear end sidewall of said handle of a knife is provided with cutting knife, and the knife bar of said cutting knife is plugged in the slot that is opened on the sidewall of handle of a knife rear end and through bolt and locatees.

The utility model advantage just is to be separately positioned on the cutter tip of said tool rest above and below; Make tool rest have two cuttings to the end; After a carbide bit wearing and tearing or damaging, still can utilize another piece carbide bit to continue cutwork, improved the utilization rate of tool rest greatly; Simultaneously also save the replacing tool rest time, improved operating efficiency.On the sidewall of the rear end of said handle of a knife, cutting knife is set, makes the utilization rate of carbon steel handle of a knife be able to further raising.

Description of drawings

Fig. 1 is that the said tool rest of the utility model is 90 ° a structural representation.

Fig. 2 is that the said tool rest of the utility model is 45 ° a structural representation.

The specific embodiment

Like Fig. 1, shown in 2; The described multi-functional combination lathe tool of the utility model; The tool rest 1, the handle of a knife 2 that comprise 90 ° or 45 ° structures; Be separately positioned on above the said tool rest 1 and following cutter tip 4,5, said tool rest 1 is one through the frustum 3 that is arranged on the tool rest 1 with the taper hole plug-in mounting that is opened in handle of a knife 2 ends with handle of a knife 2, and fixes through bindiny mechanism; Said bindiny mechanism is the connecting screw rod 6 that is arranged in handle of a knife 2 through holes, an end of said connecting screw rod 6 be opened in the screw bolt on the said frustum 3, the other end extends outside the handle of a knife 2 and nut 7 bolts.The rear end sidewall of handle of a knife 2 is provided with cutting knife 8, and the knife bar of said cutting knife 8 is plugged in the slot that is opened on the handle of a knife 2 rear end sidewalls and through bolt 9 and locatees.
