Technical Field

The utility model relates to a numerical control cutter field, concretely relates to numerical control processing cutter.

Background

With the machining industry, numerically controlled lathes are one of the most commonly used devices. The numerical control lathe needs to use a cutter during working, the existing cutters used by the numerical control lathe are mainly of two types, one type is a traditional lathe cutter, a cutter bar and a blade of the traditional lathe cutter are integrated, namely a hard alloy cutter head is welded on the carbon steel cutter bar, and the cutter point and various angles of the cutter can be used after later polishing; the second category is the more conventional mechanical clamping type turning tool, in which the tool bar and the blade are fixed by a mechanical clamping method, and the blade is generally standard. When a narrow groove needs to be formed in a workpiece to be machined, the requirement on a blade is high, and firstly, the cutting part of the blade is required to be relatively sharp, namely, the front end of the blade is relatively narrow; and secondly, the blade is required to have higher pit deformation capability, namely, the blade is not easy to break when a workpiece is processed. However, most of the blades of the machine-clamped turning tool are integrally damaged and can only be directly scrapped, the replacement steps of the blades are complex, and the use cost is high. The traditional blade cannot be made to be narrow in order to guarantee the cutting capacity during machining, namely the blade is difficult to make the tool tip thin in order to guarantee the supporting strength, so that the machining precision is low and the requirement on the machining space of the tool is strict.

The tilting of the tool nose can be realized by setting the angle between the tool nose and the bottom of the tool body to be 10-20 degrees, so that the chip removal performance of a chip removal groove and the supporting performance of the tool body to the tool nose are guaranteed.

Furthermore, the rear end part of the cutter body is provided with a limiting part, the mounting part is provided with a limiting groove corresponding to the limiting part, the limiting groove is provided with an inclined surface, and the limiting part is embedded in the limiting groove and is abutted against the inclined surface; the tool has the advantages that through the matching of the limiting part and the limiting groove, force can be applied to the limiting part by utilizing the lever principle when the tool nose performs cutting, and the limiting part and the tool handle are integrally formed, so that the tool has stronger bearing capacity, and the cutting capacity of the blade is improved. Meanwhile, the matching of the limiting groove and the limiting part can play a role in guiding and mounting, and the assembly efficiency is further improved.

Furthermore, the front end of the knife handle is arranged to be conical, and the chip discharge groove protrudes out of the front end of the knife handle; the numerical control machining cutter has the advantages that the conical cutter handle is arranged, so that the space occupied by the cutter handle can be reduced, the condition that the cutter handle is collided and interfered in the cutting process is reduced, and the reliability of the numerical control machining cutter is improved. And the chip groove protrudes out of the front end of the tool shank, so that in the cutting process, chips are smoothly discharged along the chip groove, and the chip accumulation caused by the interference with the tool shank is avoided.

Furthermore, the connecting hole is a tapered hole, and the aperture of the connecting hole is gradually reduced from the side far away from the knife handle; the advantage lies in through the conical connecting hole that sets up, can make the housing bolt have bigger area of contact with the blade when fixing the blade, can compress tightly the blade, prevents that the blade from rocking.

Compared with the prior art, the utility model has the advantages that can dismantle fixed cooperation with the blade through be provided with the mount pad on the handle of a knife, can realize the change and the maintenance of blade through connecting bolt to very big improvement the suitability of cutter, and the flexibility. And the side surface of the cutter body is tightly attached to the side edge of the lower end surface corresponding to the mounting part, and the cutter point extends out of the cutter handle, so that the support performance of the cutter blade can be further improved, and the cutter blade has stronger cutting capability. Meanwhile, the transportation capacity of the cutter is greatly improved, and the integral cutter is high in cost and inconvenient to transport during transportation. This application adopts split type structure, and the life of handle of a knife is longer, consequently change when maintaining only change the blade can, and the less occupation space of blade volume is less, and the cost of transportation is lower, comparatively is fit for big transportation in batches.
