Description

thread turning tool

technical field

The utility model relates to a turning tool, in particular to a thread turning tool, which belongs to the technical field of mechanical processing.

Background technique

The thread turning tool is a kind of cutting tool, which is a tool used for thread cutting on the turning machine tool. Thread turning tools are divided into two categories: internal thread turning tools and external thread turning tools. From the thread turning tools with welded cutter heads that need to be manually ground in the early stage of machine manufacturing, thread turning tools ground from high-speed steel materials, and high-speed steel comb blades Type thread turning tool and machine clip thread turning tool, etc. Machine clip thread turning tool is currently widely used machine clip thread turning tool. Machine clip thread turning tool is divided into two parts: tool holder and blade. There is a knife shim on the top, which is pressed with screws, and the blade is installed on the knife shim. The blade is divided into a hard alloy uncoated blade and a hard alloy coated blade. When the turning tool performs thread processing, when the cutting edge of the turning tool is damaged, it is necessary to replace the tool or replace the blade. Compared with changing the tool, only changing the blade saves time and effort, and the processing efficiency is higher, but usually there is only one blade on this type of turning tool, and the replacement of the blade still takes time. In order to further improve the processing efficiency, it is necessary to carry out Improve.

There are still some shortcomings in the current thread turning tool, such as low requirements for fixing the blade, easy to shake during the processing, and the blade is often damaged. A thread turning tool with a symmetrically fixed and fixed blade must be very popular.

Utility model content

The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a thread turning tool.

In order to solve the above technical problems, the utility model provides the following technical solutions:

The utility model provides a thread turning tool, comprising a tool handle, one end of the tool handle is provided with a tailstock; one end of the tool handle is provided with a cutter head, and a U-shaped groove is arranged inside the cutter head; one side of the U-shaped groove A blade groove is provided, and four symmetrically distributed screw holes are arranged in the middle of the blade groove; hexagon socket screws are installed inside the screw holes; a blade is installed inside the blade groove, and a gasket is installed on the surface of the blade; the gasket Four symmetrically distributed anti-loosening holes are arranged in the middle; several evenly distributed knife tips are arranged on one side of the blade.

As a preferred technical solution of the present invention, the hexagon socket head screw passes through the blade and the washer and is threadedly connected to the screw hole.

As a preferred technical solution of the utility model, the tip of the knife is V-shaped.

As a preferred technical solution of the present invention, the outer surface of the blade is on the same plane as the inner surface of the U-shaped groove.

The beneficial effects achieved by the utility model are: the blade of this thread turning tool adopts four symmetrically distributed inner hexagonal screws to securely install it on the cutter head, so that the force on the blade is uniform, and the blade is avoided due to insufficient rigidity. Jittering, cutting, etc.; the surface of the blade is installed with gaskets, and four symmetrically distributed anti-loosening holes are set in the middle of the gaskets to make the connection more compact and eliminate looseness during use; the outer surface of the blade and the inner surface of the U-shaped groove On the same plane, the cutting accuracy is greatly improved. There are several evenly distributed tool tips on one side of the blade. The number of tool tips can be selected according to the number of threads to be cut, and the operation is convenient.

detailed description

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Embodiment: As shown in Figures 1-3, the utility model provides a thread turning tool, including a handle 1, a tailstock 8 is provided at one end of the handle 1; a head 2 is provided at one end of the handle 1, and the A U-shaped groove 5 is arranged inside the cutter head 2; a blade groove 6 is arranged on one side of the U-shaped groove 5, and four symmetrically distributed screw holes 7 are arranged in the middle of the blade groove 6; Screw 3; the blade 4 is installed inside the blade groove 6, and a gasket 9 is installed on the surface of the blade 4; four symmetrically distributed anti-loosening holes 10 are arranged in the middle of the gasket 9; a number of uniform holes are arranged on one side of the blade 4 Distributed knife tip 11.

For this kind of thread turning tool, the blade is installed more firmly, and the hexagon socket head screw 3 passes through the blade 4 and the washer 9 is threadedly connected with the screw hole 7 .
