Background technique

At present, in the domestic lathe metal cutting process, the reliability of tool chip breaking has a major impact on normal production and operator safety. At present, there are more than ten kinds of chip breaking methods. At present, the method of setting chip breakers on the tool is mainly used at home and abroad to achieve the purpose of chip breaking. This method is simple and feasible, but it can only be realized under certain cutting conditions. Chip breaking, because a chip breaking geometry size can only be adapted to a certain workpiece material, cutting amount and tool geometry. However, the cutting process is carried out under changing conditions. For example, the tool will be worn under the action of cutting force and cutting heat, thereby changing its groove size and geometric angle, which often cannot achieve the purpose of stable and reliable chip breaking. . Some also use the method of welding a chip breaker in front of the blade for chip breaking. At the same time, these methods reduce the service life of the tool.

Application number: 00207105.3 The technical solution adopted by the invention: a turning tool chip breaking device includes an adjusting support, an adjusting screw, a fastening screw, a semicircular body, a turning tool, a chip breaking control block, a pressing screw, a clamping screw, a lathe Tool holder, tool holder screw, tool rod, screw, nut, and the feature is that the turning tool is installed in the semicircular body and fixed by the clamping screw. The upper end of the turning tool has a chip breaking control block and is fixed by the compression screw. The seat is installed on the outer end of the semicircle body, and there is a groove inside the semicircle body, and it is equipped with an adjusting screw and a fastening screw. There is a hole in the knife rod, and the screw is fixed by a nut after passing through the knife rod and the semicircle body once, and loosened Fasten the screw, adjust the position of the chip breaking control block and the turning tool by adjusting the support, loosen the set screw, adjust the height of the chip breaking control block and the turning tool by adjusting the support, loosen the screw and The angle of the nut and the semicircular body can be adjusted as required. There is a straight groove on the chip breaking control block, and two compression screws are fixed. After loosening the compression screws, adjust the chip breaking control block with the adjusting screw.

However, in the prior art, there are generally problems with chip breaking devices for turning tools. Most chip breaking devices can not only adjust the size of the chip breaker, but also adjust the height and position of the chip breaking control block and the required angle with the blade; Moreover, the production cost of many chip breaking devices is relatively high.

Utility model content

In order to solve the above problems, the utility model provides an adjustable chip breaking device for mechanically clamping turning tools. The specific plan is as follows:

An adjustable chip breaking device for mechanically clamping a turning tool, comprising a tool bar, a tool shim, a U-shaped pressing plate, a screw rod, a hexagonal nut, a pressing screw, a fastening screw, a chip breaking control block and a blade. The tool shim is connected with the tool bar through the compression screw; the U-shaped pressure plate is fixed on the tool bar through the fastening screw, and the U-shaped pressure plate and the screw constitute the compression device; the blade and the chip breaking control block are fastened by the screw and the hexagon nut; loose Open the hexagonal nut, adjust the chip breaking control block to the desired position, tighten the hexagonal nut again to tighten the chip breaking control block, during the cutting process, it can be adjusted according to different cutting conditions; insert the thin steel rod into the hole at the upper end of the screw , unscrew the screw, adjust the required height position of the chip breaking control block and the blade, and then the turning process can be carried out.

The beneficial effects of the utility model are:

1. By adjusting the hex nut, the angle between the chip breaking control block and the blade can be adjusted, and the operation is simple and easy;

2. Loosen the screw to adjust the required height of the blade and the chip breaking control block. The operation saves time and effort, the device is simple, and the chip breaking efficiency is high.
