The quick-change device based on the magnetic attraction principle of the present invention is further described with reference to fig. 1 to 3.
The utility model provides a quick change device based on principle is inhaled to magnetism, characterized by: including end web 6 and workpiece web 5. A first magnet array 7 is arranged in the end connecting plate 6. The workpiece connecting plate 5 is provided with a connecting part 51 for connecting the workpieces 3, the workpiece connecting plate 5 is internally provided with a second magnet array 8, the magnets in the first magnet array 7 can correspond to the magnets in the second magnet array 8 one by one and are mutually adsorbed, namely NS special-shaped adsorption, so that the workpiece connecting plate 5 is assembled on the tail end connecting plate 6.
Specifically, the end connecting plate 6 has a positioning column 61 in the center of the fitting surface facing the workpiece connecting plate 5, and the workpiece connecting plate 5 has a positioning hole in the center of the fitting surface facing the end connecting plate 6, into which the positioning column 61 is inserted.
The magnets in the first magnet array 7 are uniformly distributed in a circumferential manner by taking the positioning column 61 as a circle center; the magnets in the second magnet array 8 are uniformly distributed in a circumference shape by taking the positioning hole as the center of a circle. In this embodiment, the number of the magnets in the first magnet array and the number of the magnets in the second magnet array 8 are four, and it should be noted that the specific number of the magnets can be adjusted according to actual use requirements, such as the size of the connecting plate. The workpiece connecting plate 5 and the tail end connecting plate 6 are respectively provided with a mounting counter bore which is used for mounting and fixing the magnet.
In the above structure, the end connecting plate 6 has a connecting hole 62, and the end connecting plate 6 is connected to the robot arm through the connecting hole 62 for quick assembly or quick disassembly of the workpiece connecting plate 5 to which the workpiece 3 is connected. The concrete fast-assembling process is as follows: magnets in the second magnet array 8 in the workpiece connecting plate 5 and magnets in the first magnet array 7 in the tail end connecting plate 6 are in a pair, and NS poles are attracted in opposite directions; in the process, as long as the first magnet array 7 and the second magnet array 8 are basically aligned, the magnetic attraction between the first magnet array 7 and the second magnet array can be automatically attracted, deflected and aligned, and the positioning column 61 of the tail end connecting plate 6 can be accurately inserted into the positioning hole in the workpiece connecting plate 5 under the action of the magnetic attraction, so that the quick and convenient quick assembly action is realized; meanwhile, under the action of the attraction of the four pairs of magnets and the matching structure of the positioning columns and the positioning holes, the workpiece 3 can be effectively prevented from overturning and overturning possibly in the moving process, and the positioning stability is ensured. The specific quick-release process is as follows: when the workpiece connecting plate 5 is connected to the tail end connecting plate 6, magnets in the first magnet array 7 and magnets in the second magnet array 8 are fixedly installed in an NS pole opposite attraction mode, four magnets on the same side of the workpiece 3 can form a closed magnetic field loop, when the workpiece connecting plate 5 and the tail end connecting plate 6 rotate at an angle of 45 degrees relatively, magnetic field lines on the workpiece connecting plate 5 and the tail end connecting plate 6 are mutually exclusive, and at the moment, the workpiece connecting plate 5 and the tail end connecting plate 6 can be easily separated by means of the magnetic force of the mutual exclusion, and the quick-release action is achieved.
In this embodiment, the magnets in the first magnet array 7 and the second magnet array 8 are both electromagnets.
The connecting portion 51 is a connecting column which is formed on the side surface of the workpiece connecting plate 5, which faces away from the tail end connecting plate 6, and has external threads on the outer side wall thereof, a connecting hole is formed in the end portion of the workpiece 3, and internal threads are formed in the connecting hole, so that the workpiece 3 is mounted on the workpiece connecting plate 5.

The positioning nut 4 is screwed on the connecting portion 51, and two positioning blocks 41 are arranged on the outer side wall of the positioning nut 4, and the two positioning blocks 41 are symmetrically arranged on the connecting portion 51. The fixing seat 1 is provided with a female positioning seat, the female positioning seat is provided with a storage groove 2, and the inner wall of the storage groove 2 is provided with a positioning groove 21 for matching with a positioning block 41. In the operation process, the fixed seat 1 is installed on a workpiece storage device, and after the workpieces 3, the workpiece connecting plate 5 and the positioning nuts 4 are detached from the tail end connecting plate 6, the workpieces 3 can be stored in the storage groove 2 through the matching of the positioning grooves 21 and the positioning blocks 41, so that the workpieces 3 can be conveniently stored and taken out.
The inlet of the positioning groove 21 is of a flaring 211 type structure, and the positioning block 41 can conveniently slide into the positioning groove 21 under the structure, so that the workpiece 3, the workpiece connecting plate 5 and the positioning nut 4 can be conveniently placed into the storage groove 2.
