Description

A combination turning tool with adjustable large cutting depth

Technical field

The utility model belongs to the field of machining, in particular to a combination turning tool with an adjustable large cutting depth, which is used for processing shaft workpieces and is suitable for rough machining of workpieces on lathes and achieving large cutting amounts.

Background technique

A lathe is a machine tool that mainly uses turning tools to turn rotating workpieces. Turning tools are essential components of lathes. When using a lathe to process workpieces, multiple turning processes are required. When turning, the amount of turning is generally large and multiple turns are required.

Currently, when processing shaft parts, lathe processing requires multiple turns, which is time-consuming and has low production efficiency.

Contents of the invention

In order to overcome the shortcomings and existing problems of the existing technology, the present utility model provides a combination turning tool with an adjustable large cutting depth. One of the means to improve the material removal rate is to use a large cutting depth, but an excessive cutting depth will produce If the load exceeds the strength of the turning tool, it will cause the tool to chip.

The utility model is realized through the following technical solutions:

A combination turning tool with an adjustable large cutting depth, the turning tool handle, the front end of the turning tool handle is a first turning tool, the first turning tool and the tool handle are connected to each other as a whole, and the tool head is used to install rough cutting tools. Turning blade, the rear end is the second turning tool, and its tool head is used to install the rough turning blade. The blades of the first turning tool and the second turning tool are fixed in the blade groove at the front end of the tool head with locking screws.

A threaded hole is provided on the side of the tool handle. The second turning tool is fixed in the tool body with a locking bolt, and a fine-tuning screw is pushed against its rear end to adjust the cutting depth as needed.

There is a height difference between the second turning tool and the first turning tool when the tool shank is installed, which is the cutting depth of the second turning tool, so that the cutting depth of one turning is the cutting depth of the first turning tool and the cutting depth of the second turning tool. Sum. The cutting depth achieved by one-feed turning is greater than that achieved by using only the first turning tool.

The blades of the first turning tool and the second turning tool are indexable blades.

In order to realize turning with a large cutting depth and prevent the turning tool from being damaged due to excessive load, the cutting depth of the second turning tool should not exceed the cutting depth of the first turning tool.

The turning tool also includes a pressing plate and a pressing bolt. The first turning tool head is provided with a blade slot, and the thick blade is correspondingly placed in the first turning tool head blade slot. The pressing plate is fixed with the pressing bolt. . The second turning tool head is also provided with a blade groove, and the thick blade is correspondingly placed in the blade groove of the second turning tool head, and the pressure plate is fixed with the compression bolt.

The second turning tool can be replaced as needed.

The blade body is made of No. 45 steel.

The utility model is provided with two turning tools, and the two turning tools are staggered front and back. The turning tool located at the rear end in the turning direction protrudes from the turning tool at the front end. One turning process can complete the cutting depth of the two turning tools, achieving a large cutting depth. The purpose is to reduce the total number of turnings, improve work efficiency, save time and reduce costs.

Detailed ways

As shown in Figures 1 to 3, a combination turning tool with an adjustable large cutting depth includes a turning tool handle. One end of the tool handle is provided with two turning tools side by side, and the turning tool heads are equipped with insert grooves. , the blade slot is equipped with a rough turning blade. The ends of the two turning tool blades are staggered, and the blade at the rear end in the turning direction protrudes from the blade at the front end in the turning direction. The amount of protrusion is the cutting depth at the rear end in the turning direction.

The blades of the first turning tool and the second turning tool are both indexable inserts.

The second turning tool is fixed on the tool handle with a locking bolt on the side of the tool body, and a screw hole is provided at its rear end, and the cutting depth of the second turning tool is adjusted with a fine-tuning screw.

When turning the workpiece, set the cutting depth of the first turning tool and then perform turning. The second turning tool adjusts the cutting depth based on the first turning tool.

The working process of the utility model: fix the entire turning tool on the machine tool through the tool handle, adjust the cutting depth of the two turning tools according to the needs, and the cutting depth of the two turning tools can be completed in one turning process.

The above embodiments are preferred implementations of the present invention and are not intended to limit the present invention. It should be pointed out that for those skilled in the art, any obvious substitutions without departing from the inventive concept of the present utility model are within the protection scope of the present utility model.
