Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present utility model. Furthermore, in the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 1-4, the present utility model provides a technical solution: a special-shaped chip breaking boss turning tool comprises a tool body 1, wherein the tool body 1 comprises a tool handle 2 and a blade part 3 which are integrally formed, the front end of the blade part 3 is provided with a blade mounting groove 5, and the rear end of the blade part 3 is provided with a butterfly-shaped groove 4; the blade 10 is arranged in the blade mounting groove 5, the pressing block 6 is arranged in the butterfly groove 4, and the blade 10 is arranged on the blade body 1 through the pressing block 6 and the screw.

In the embodiment, the length of the cutter handle 2 is 120mm, the length of the blade part 3 is 65mm, the angle between the blade part 3 and the cutter handle 2 is 45 degrees, and the thickness of the cutter handle 2 is 40mm.

Wherein, the cutter body 1 is provided with a screw hole matched with the screw, the cutter body 1 is provided with a groove type chip groove, and the front angle of the cutter blade 10 is 8-12 degrees.

The pressing block 6 comprises a butterfly-shaped tail part 7, a pressing cutter head part 8 and a step-shaped connecting part 9 for connecting the butterfly-shaped tail part 7 and the pressing cutter head part 8, wherein a counter bore matched with a screw is formed in the step-shaped connecting part 9.

The utility model discloses a special-shaped chip breaking boss turning tool with a replaceable hard alloy blade 10, which consists of a tool body 1, the blade 10, a pressing block 6 and screws.

Analysis of the machining of the train wheel resulted in the best structure explored by the test route being the vertically mounted clamped indexable insert 10, and the system analysis was used in designing the cutting insert 10.

From a view of the tool, a necessary link exists between structural and functional aspects and forms a unified whole. The system analysis offers the possibility to divide the tool design task into several parts and take the best solution.

According to the utility model, the rear end of the blade part 3 of the cutter body 1 is optimized into the butterfly groove 4, and after the pressing block 6 is embedded into the butterfly groove 4, the blade 10 and the cutter body 1 are pressed by the pressing block 6 and the screw, and as the butterfly groove 4 has a special structure, the arm of force can be increased, so that the blade 10 and the cutter body 1 are tightly contacted, and the loosening of the blade 10 after clamping is avoided.

Because the chip breaking grooves of the traditional turning tool blade 10 are flat grooves and have poor chip breaking capacity, the chip breaking capacity can be effectively increased by adding the groove type chip breaking grooves through the optimization of the pressing block 6, and in order to prevent interference when the cutter tip is used for processing the arc-shaped groove, the distance between the cutter tip and the chip breaking boss is generally 2.5mm-4mm, so that the interference is effectively prevented.

As shown in fig. 1, the cutter tip is located on the centerline, and the rake angle of the blade 10 is 8 ° -12 °.

The rear end of the pressing block 6 is matched with the butterfly groove 4 by utilizing the butterfly groove 4, so that the force arm can be effectively increased. The angle of the pressing block 6 is consistent with the angle of the cutter groove of the cutter body 1, and the counter bore is used for assembling a screw.

By studying the performance of the insert 10 under production conditions, the structural optimization method can improve the cutter strength and can obtain stable broken chips in the whole wheel contour machining. And simple structure, convenient operation, location and clamping that can be quick ensure machining precision and surface quality when grinding, when cutter life reaches the limit, removable blade 10 continues processing, has still solved the difficult problem of broken bits.

The blade 10 is arranged on the cutter body 1 and is tightly pressed with the screw through the pressing block 6, when train wheels are machined, the cutting edges of the blade 10 and other parts are worn by different degrees after cutting for many times, and when the cutter reaches the wear limit, the blade 10 is replaced, so that the cutter body 1 can be reused, and the cutter cost is saved.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
