The sensor 3 is arranged beside the rotary worktable 1, the sensor 3 is used for shooting the outline of the irregular workpiece 2, and particularly, the sensor 3 can be arranged above the center of the rotary worktable 1, so that the outline of the irregular workpiece 2 can be shot visually. Meanwhile, if the size of the irregular workpiece 2 is too large, local shooting can be performed by arranging a plurality of sensors 3, and then all local images are integrated into a complete contour map. The sensor 3 may be a camera or the like.
The irregular workpiece 2 is mainly cut by the cutting operation mechanism 4, namely, the rotary worktable 1 and the cutting operation mechanism 4 can move relatively to be close to each other, and then the cutting operation mechanism 4 can cut the irregular workpiece 2. The cutting operation mechanism 4 can move close to the rotary table 1 to cut the irregular workpiece 2, and specifically, the cutting operation mechanism 4 can move integrally in a manner of being connected with components such as a sliding rail or a mechanical arm. The rotary table 1 may be moved closer to the cutting operation mechanism 4 to cut the irregular workpiece 2, and similarly, the rotary table 1 may be placed on the sliding rail to move integrally. As described above, not only can the cutting of the double pendulum be realized by the rotation of the rotary table 1, but also the cutting of the double pendulum can be realized by the cutting operation mechanism 4 which is provided to rotate clockwise and counterclockwise along the circumferential direction of the rotary table 1.

The invention also provides a method for cutting the workpiece made of the irregular brittle and hard material, and the method can be operated by applying the cutting equipment. The method specifically comprises the following steps:
s1, placing the irregular workpiece 2 on the rotary table 1;
s2, shooting the outline of the irregular workpiece 2 through the sensor 3 to obtain an outline drawing of the irregular workpiece 2;
s3, we will divide the first cutting region 21 and the second cutting region 22 of the irregular workpiece 2 according to the profile map, the second cutting region 22 is the largest circle in the profile map (refer to the dotted circular region on the irregular workpiece 2 shown in fig. 4), the first cutting region is the region outside the largest circle,

Specifically, the maximum value is the position of the irregular workpiece 2 farthest from the center point of the rotary table 1, the maximum common value is the radius of the maximum circle of the irregular workpiece 2, and the range of the maximum circle covers most of the irregular workpiece 2. If the maximum value of the irregular workpiece 2 is much greater than the maximum common value, a significant portion of the area will be left free if a rotary cut is used directly at the maximum value. The angle of the swing range of the rotary table 1 and the distance of the moving close between the rotary table 1 and the cutting running mechanism 4 can be adjusted according to the actual situation of the second cutting area 22. The cutting operation mechanism 4 firstly performs the compound pendulum cutting on the first cutting area 21 from outside to inside, and in the cutting process of the compound pendulum cutting, the remaining range of the first cutting area 21 can be judged by shooting the obtained contour map of the irregular workpiece 2 in real time through the sensor 3, so that the swing angle of the compound pendulum cutting and the moving approaching distance of the cutting operation mechanism 4 and the rotary worktable 1 can be adjusted in real time.
The complex-swinging cutting between the rotary table 1 and the cutting running mechanism 4 can be complex-swinging through the reciprocating rotation of the rotary table 1. The method comprises the following specific steps:
the rotary worktable 1 alternately rotates in a reciprocating manner in the clockwise direction and the anticlockwise direction within the range determined according to the diameter value of the wheel disc and the corresponding angle value, and then drives the irregular workpiece 2 to swing in a reciprocating manner;
the cutting operation mechanism 4 and the rotary table 1 move relatively to each other to make the cutting operation mechanism 4 cut the first cutting area 21 of the irregular workpiece 2.
Meanwhile, the complex pendulum cutting between the rotary table 1 and the cutting operation mechanism 4 can also be realized by the swing of the cutting operation mechanism 4, different from the above mode, the specific steps are as follows:
the cutting running mechanism 4 alternately swings in a reciprocating manner in the clockwise direction and the anticlockwise direction within the range determined according to the diameter value of the wheel disc and the corresponding angle value;
the cutting operation mechanism 4 and the rotary table 1 move relatively to approach each other, so that the cutting operation mechanism 4 performs compound pendulum cutting on the first cutting area 21 of the irregular workpiece 2.

when the irregular workpiece 2 is subjected to the repeated swinging cutting to the maximum public value, the repeated swinging cutting is switched to the rotary cutting, and the rest part of the irregular workpiece 2 is continuously cut;
the rotary cutting is that the rotary working table 1 drives the irregular workpiece 2 to rotate clockwise or anticlockwise, and meanwhile, the rotary working table 1 and the cutting operation mechanism 4 move towards each other to enable the cutting operation mechanism 4 to cut the irregular workpiece 2. Through the operation, the effective cutting working hour utilization rate is improved.
