Implementation 1:

a triangular groove cutter convenient for chip removal is used for forming a groove on the inner wall of a bearing ring, as shown in figure 1, the triangular groove cutter 1 comprises a cutter body 101 and cutter heads 103 fixed at three angular positions of the cutter body 101, wherein 3 cutter heads 103 are completely identical, and the surface of the cutter body 101 is provided with chip removal grooves 105 corresponding to the cutter heads 103 one by one and used for removing waste chips during groove turning.

In addition, as shown in fig. 1, the surface of the tool bit 103 is a transition surface 102, the transition surface 102 is smoothly connected with the chip discharge groove 105, and the transition surface 102 transfers the waste chips into the chip discharge groove 105 to discharge the waste chips.

Both sides of the tool bit 103 are provided with a limiting surface 104 for positioning the depth of the channel groove.

The tail of the chip groove 105 is provided with an auxiliary groove 106, so that the waste chips can be discharged conveniently.

The auxiliary groove 106 is a concave arc-shaped surface, so that the scraps in the scrap discharge groove are discharged to the outside through the concave arc-shaped surface, and the scraps cannot drop at the vehicle groove position, so that the scraps are prevented from being accumulated at the working position, the jamming is avoided, and the quality and the efficiency of the vehicle groove are improved. On the other hand, the discharging direction of the scraps can be changed, and the scraps are prevented from falling on the working position.

Example 2:

on the basis of embodiment 1, as shown in fig. 3, a guide plate 107 is disposed in the middle of the chip discharge groove 105 for guiding the chips, the guide plate 107 extends from the middle of the chip discharge groove 105 to the tail, and the guide plate 107 is fixed to the edge near one side of the cutter body 101, so that the chips are prevented from flying around when moving from the middle of the chip discharge groove 105 to the tail.

The guide plate 107 is in an obtuse triangle shape, a small acute angle (namely, an angle A) of the obtuse triangle is connected to the middle of the chip groove 105, a large acute angle (namely, an angle B) of the obtuse triangle is connected to the tail of the chip groove 105, an obtuse angle (namely, an angle C) of the obtuse triangle faces towards the outside of the cutter body 101, a first long edge (namely, an edge AB) of the obtuse triangle is connected with the side edge of the cutter body 101, the formed form is as shown in figure 3, the width of the angle A at the front end is small, and scraps and the chip groove 105 are convenient to smoothly enter the rear part of the chip groove, so that the scraps are conveniently discharged in the follow-up direction of the guide plate.

The downside of deflector 107 with arc connection between the chip groove 105, the thickness that the long limit of deflector 107 second is AC limit position is less than the thickness that first long limit is AB limit position for in the same direction as smooth connection between deflector and the chip groove, make things convenient for the sweeps to discharge more.

The deflector 107 level sets up for the sweeps discharge direction can not drop in the trench position for the outside of operating position is the outside of tool bit, avoids influencing the quality in trench, prevents to block.

The auxiliary channel 106 allows for a more advantageous and faster discharge of the waste. The guide plate 107 facilitates the waste scraps to be discharged to the outside instead of being discharged downwards, so that the waste scraps are discharged towards a far distance when falling, in the prior art, the waste scraps directly fly out of the scrap discharge groove 105, the flying direction, namely the discharging direction, is upward, when the waste scraps are separated from the bearing, the waste scraps move upwards again, and under the action of gravity, the waste scraps automatically fall in an arc shape, and then fall to the working positions of the cutter head and the bearing, so as to influence the work of the vehicle groove, in the embodiment, a guide plate is arranged, the waste scraps are blocked at the upper part, so that part of the waste scraps move outwards after being blocked, as shown in the arrow direction in figure 3, the waste scraps are discharged towards the outer part of the bearing under the power of the vehicle groove, fall towards the far distance and towards the outer arc shape, and cannot fall onto the working position of the bearing, so as not to influence the vehicle groove, and the other part of the waste scraps are discharged along the auxiliary groove 106, and likewise will not fall into the working position.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
