Referring to fig. 1 and 2, the present application provides a cutting apparatus 100, wherein the cutting apparatus 100 includes a base 10, a loading mechanism 20 and a cutting mechanism 30.

The loading mechanism 20 is disposed on the base 10, the loading mechanism 20 includes a first rotating assembly 210, a second rotating assembly 220 and a loading seat 230, and the first rotating assembly 210 can drive the second rotating assembly 220 to rotate around a first axis W1. The loading base 230 is connected to the second rotating assembly 220 and can be used for placing a workpiece G to be processed. The second rotating assembly 220 can drive the material loading seat 230 to rotate around the second axis W2. The second axis W2 is perpendicular to the first axis W1, that is, the first rotating assembly 210 and the second rotating assembly 220 rotate the material loading base 230 in two directions perpendicular to each other, so that the spatial posture of the workpiece G loaded on the material loading base 230 can be effectively adjusted, the cutting mechanism 30 can cut the workpiece G, the dead angle of the workpiece G can be eliminated, and accurate cutting can be realized.

The cutting mechanism 30 includes a cutting head 310 and a moving assembly 320, wherein the moving assembly 320 can drive the cutting head 310 to move relative to the loading base 230 so as to cut the workpiece G to be processed placed on the loading base 230.

The moving assembly 320 includes a six-axis robot, which is mounted to the base 10, and an output end 320a of the six-axis robot is connected with the cutting head 310. The six-axis robot can realize six-degree-of-freedom motion, and the material loading seat 230 of the material loading mechanism 20 is matched with two degrees of freedom rotating around the first axis W1 and the second axis W2, so that the cutting equipment 100 has eight degrees of freedom, the space cutting postures of the workpieces G are greatly enriched, and the processing requirements of various complex workpieces G are met. For example, when cutting a complicated tubular workpiece G, the tubular workpiece G is loaded on the carriage 230, and the tubular workpiece G is moved to a proper orientation by the first rotating assembly 210 and the second rotating assembly 220, respectively, so that the six-axis robot moves the cutting head 310 to perform an all-directional cutting operation on the tubular workpiece G at a position where the tubular workpiece G is to be cut.

In one embodiment, the first rotating assembly 210 includes a first motor 211 and a swing arm 250. The output shaft 211a of the first motor 211 is connected to the swing arm 250, and the first motor 211 can drive the swing arm 250 to rotate around the first axis W1. With this arrangement, the operating state of the first motor 211 is controlled, so that the rotation angle of the swing arm 250 can be adjusted. For example, in some embodiments, the first motor 211 drives the swing arm 250 to rotate 360 degrees about the first axis W1. In other embodiments, the first motor 211 drives the swing arm 250 to swing within 90 degrees of forward and reverse rotation about the first axis W1.

With continued reference to fig. 1 and 2, the swing arm 250 is "L" shaped. The material loading seat 230 is disposed on the swing arm 250 through the second rotating assembly 220, and the material loading seat 230 is disposed on one side of the swing arm 250 close to the first axis W1, so that when the swing arm 250 rotates around the first axis W1, the rotation range of the material loading seat 230 relative to the first axis W1 is not large, and the requirement of adjusting the spatial attitude of the small workpiece G is met. Correspondingly, when a large workpiece G needs to be machined and the material loading seat 230 needs to move greatly in space, the size of the swing arm 250 and the arrangement positions of the second rotating assembly 220 and the material loading seat 230 can be changed.

The cutting apparatus 100 further includes a support base 240, and the loading mechanism 20 is supported by the support base 240.

Specifically, the supporting base 240 is connected to the base 10, and the first motor 211 is mounted to the supporting base 240 through the motor mounting base 212.

The motor mounting seat 212 is detachably mounted on the supporting seat 240, so that when the mounting angle of the first motor 211 needs to be changed, the structures of the first motor 211 and the supporting seat 240 do not need to be changed, and only the mounting position of the motor mounting seat 212 on the supporting seat 240 needs to be changed. In this structure, the motor mounting seat 212 and the supporting seat 240 are provided with mounting holes at corresponding positions to accommodate the detachable connection therebetween.

As shown in fig. 3, the output shaft 211a of the first motor 211 is connected to the swing arm 250 through the reducer 213, so that a large moment is provided by reducing the rotation speed, so that the swing arm 250 can smoothly rotate around the first axis W1 even if it receives a large weight during the rotation. It is understood that the speed reducer 213 may be a speed reducing structure such as a planetary speed reducer commonly used in the market, as long as the transmission ratio between the output shaft 211a of the first motor 211 and the swing arm 250 can be adjusted.

The swing arm 250 has a first end 251 and a second end 252 opposite to each other, the first end 251 is connected to the output shaft 211a of the first motor 211, the second end 252 is opened with a mounting groove 253, and the second rotating assembly 220 is mounted in the mounting groove 253.

The second rotating assembly 220 includes a second motor 221 and a rotating disc 222, the second motor 221 is fixed at the second end 252, the rotating disc 222 is disposed at a position opposite to the mounting groove 253 and connected to an output shaft 221a of the second motor 221, and the rotating disc 222 can rotate around a second axis W2 under the driving of the second motor 221.

Referring to fig. 2 and 3, the rotary plate 222 includes a flange to which the carrier block 230 is coupled.

The carrier 230 is disposed at the center of the flange, and more specifically, the carrier 230 is disposed on the second axis W2 along which the flange rotates with the output shaft 221a of the second motor 221. Thus, when the output shaft 221a of the second motor 221 rotates, the flange drives the carrier 230 to rotate, so that the posture of the workpiece G on the carrier 230 is adjusted only in the direction around the second axis W2 without a large positional change in the direction perpendicular to the second axis W2. This arrangement is advantageous in reducing the complexity of calculating the relative positions of the cutting head 310 and the workpiece G during cutting, and simplifying the motion control of the various mechanisms of the cutting apparatus 100.

The cutting apparatus 100 further includes a speed reducer 223, the speed reducer 223 is disposed in the mounting groove 253, and the output shaft 221a of the second motor 221 is coupled to the flange through the speed reducer 223. It is understood that the speed reducer 223 can be a speed reducing structure such as a planetary gear speed reducer commonly used in the market, as long as the transmission ratio between the output shaft 221a of the second motor 221 and the flange can be adjusted.

The side wall of the mounting groove 253 may have a circular cross-section so that the mounting groove 253 can be used as a seat body of a swivel structure. For example, a part of the structure of the rotary disk 222 is rotatably embedded in the installation groove 253, so that a base of the rotary disk 222 does not need to be separately arranged, and a part of the swing arm 250, which is provided with the installation groove 253, is used as a base, thereby simplifying the assembly structure.

It should be noted that the rotary disc 222 may be disposed in the mounting groove 253 through a rolling bearing, so as to improve the rotation flexibility of the rotary disc 222 by using the rolling bearing, so that the rotary disc 222 can smoothly rotate, and the position of the workpiece G is accurately adjusted by the material loading seat 230, so as to improve the cutting precision of the workpiece G.

The material loading seat 230 is provided with a bayonet 231, and the bayonet 231 can be used for clamping and fixing a workpiece G to be processed. Before cutting the workpiece G, the workpiece G is installed at the bayonet 231, and the workpiece G is stably fixed by the bayonet 231, so that the phenomenon that the cutting effect is influenced by the looseness of the workpiece G in the cutting process is avoided.

The cross section of the side wall of the bayonet 231 can be circular, so as to meet the clamping requirement of a cylindrical pipe workpiece.
