Abstract

The utility model discloses a hard alloy spiral groove cutter fixing structure which comprises a cutter handle, a combined cutter head and a pressing plate, wherein the cutter handle is provided with a cutting edge; the combined cutter head comprises a cutter head and a blade fixed on the cutter head; one end of the combined tool bit penetrates through the pressing plate and is arranged at the notch on the tool shank; the knife handle is connected with the pressing plate; the pressing plate is provided with a screw hole; the screw hole is connected with the bolt that cooperates with the screw hole, and the bolt is used for fixed tool bit. A pressing plate and a bolt are designed on the cutter handle and used for fixing the cutter head. In actual operation, only need unscrew the bolt, rotate the tool bit to required position, tighten the bolt again and can realize rotating the function of tool bit, the conversion process is more nimble than conventional mode, and is quick. According to the utility model, the V-shaped groove with a certain degree is designed at the groove-lacking position on the cutter handle, so that the multistage rotation of the cutter head can be controlled, the problem that the manually-rotated cutter head cannot accurately rotate to a correct angle is avoided, and the processing requirements of products with different spiral directions (left-handed rotation or right-handed rotation) and arbitrary lead angles are met.

Description

Hard alloy spiral groove cutter fixing structure

Technical Field

The utility model relates to the technical field of machining, in particular to a hard alloy spiral groove cutter fixing structure.

Background

Machining refers to a process of changing the physical dimensions or properties of a workpiece by a mechanical device. The difference in the machining method can be divided into cutting machining and pressing machining.

The spiral groove is machined on a blank, which is a relatively complex operation in machining, and the conventional spiral groove machining tool is mainly characterized in that a tool bit is fixed on a tool shank, and then the tool shank is connected with an operating device. However, when the tool bit needs to be rotated to process spiral grooves in different forms, the tool holder needs to be detached from the operating arm, and then different angle wedge blocks are combined to adjust or purchase the whole tool with different lift angles, so that the operation is complex and tedious, and the tool cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a hard alloy spiral groove cutter fixing structure. So as to provide a fixing structure which can facilitate the rotation of the cutter.

In order to achieve the above object, an embodiment of the present invention provides a fixing structure for a hard alloy spiral groove cutting tool, including a tool shank, a combined tool bit and a pressing plate; the combined cutter head comprises a cutter head and a blade fixed on the cutter head; one end of the combined tool bit penetrates through the pressing plate and is arranged at the notch on the tool handle; the knife handle is connected with the pressing plate; the pressing plate is provided with a screw hole; the screw hole is connected with the bolt that cooperates with the screw hole, and the bolt is used for fixed tool bit.

In order to realize a more complete scheme of the rotary cutter fixing structure, the following preferable design is performed.

Preferably, the notch is provided with a plurality of V-shaped grooves.

Preferably, the degree of the V-shaped groove is 50 to 70 degrees.

Preferably, the platen layer is of a C-type construction.

In summary, the utility model has the following advantages:

1. according to the utility model, the pressing plate and the bolt are designed on the cutter handle to be used for fixing the cutter head. In actual operation, only need unscrew the bolt, rotate the tool bit to required position, tighten the bolt again and can realize rotating the function of tool bit, the conversion process is more nimble than conventional mode, and is quick.

2. According to the utility model, the V-shaped groove with a certain degree is designed at the groove-lacking position on the knife handle, so that the multistage rotation of the knife head can be controlled, and the problem that the knife head cannot be rotated to a correct angle by manually rotating the knife head is avoided.

Detailed Description

The utility model provides a hard alloy spiral groove cutter fixing structure which comprises a cutter handle 1, a combined cutter head and a pressing plate 3, wherein one end of the cutter head 2 is of an L-shaped structure, and a blade 4 is welded on the plane of the L-shaped structure. This ensures the stability of the blade 4 when cutting metal. The other end of the combined tool bit penetrates through the center line of the pressing plate 3 and is placed at the notch of the tool handle 1. The tool holder 1 is connected with the pressing plate 3, a screw hole is formed in the pressing plate 3, the screw hole is connected with a bolt 5 matched with the screw hole, and the bolt 5 is used for fixing the tool bit.

The pressing plate 3 is provided with a bolt 5 for fixing the gang head. After the combined cutter head is rotated, the combined cutter head can be fixed by rotating the bolt 5.

In this embodiment, the notch is provided with a plurality of V-shaped grooves with an angle of 60 °. The V-shaped groove with the angle can realize multi-stage adjustment of the combined tool bit.

In this embodiment, the pressing plate 3 is a C-shaped structure, so that the combined tool bit can be conveniently surrounded. The stability of machining is guaranteed.

While the present invention has been described in detail with reference to the illustrated embodiments, it should not be construed as limited to the scope of the present patent. Various modifications and changes may be made by those skilled in the art without inventive step within the scope of the appended claims.
