[0031] The embodiment is described in detail in conjunction with the drawings of the specification.

[0032] The skilled person, in view of the comprehensive consideration of the actual operation situation and the deep understanding of the working principle of permanent magnet, innovates the permanent magnet operation grabber.

[0033] The embodiment will be illustrated in conjunction with the drawings attached to the specification Figure 1 to the attached Figure 7 , its structure, principles and methods of use to make more refined.

[0034] The multifunctional magnetic gripper includes a handle frame, a strong magnetic block, a guard plate, a lower pressing block and a top rod, and a connecting rod. The handle frame 100 is a rectangular frame with a certain thickness, which is also a mounting mechanical frame for other parts.

[0035] An installation protrusion 110 is formed at the upper right corner of the handle frame 100 and extends outward, and the installation protrusion has an installation groove therein. A connecting rod 120 is installed in the installation groove through a pin. Further, a long hole 121 is provided on the connecting rod at the hinge point, and the long hole 121 is connected with the pin in a hinged manner, so that the connecting rod has a hinged and relative sliding movement.

[0036] A rectangular window is provided at the center of the handle frame 100, which is also a hand holding part. The upper edge of the handle frame is a hand holding part, which has a hand holding contour for easy gripping. The lower edge of the handle frame 100 is a strong magnetic block mounting position. The strong magnetic block is first fixed in a rigid protective shell 210, which is a circular part. A circular groove is formed in the rigid protective shell 210, and the strong magnetic block is placed in the circular groove. High-strength screws 220 are used to fix the strong magnetic block and the rigid protective shell on the lower edge, completing the first fixation. The fixed strong magnetic block is firmly fixed on the lower edge.

[0037] In this embodiment, the handle frame can be a metal machined part or an aluminum casting part. When it is an aluminum casting part, the tool has the advantage of being lighter in weight.

[0038] Circular holes are provided in the side edges of the handle frame 100, for example, two circular holes are formed by drilling. A first top rod 310 and a second top rod 320 are installed in the two circular holes respectively, and the two top rods are in sliding mechanical cooperation. The top of the first top rod 310 is hingedly connected with a lower pressing block 330, which is a strip-shaped structure. The other end of the lower pressing block 330 is hingedly connected with the top of the connecting rod 120. That is, the lower pressing block is synchronously hingedly connected with the first top rod and the connecting rod, and the hinged connection is achieved by a steel pin. The second top rod 320 is in contact abutting connection with the lower edge of the lower pressing block. In this embodiment, the first top rod and the second top rod penetrate the handle frame and are flush with the strong magnetic block at the lower end, so as to separate the workpiece from the strong magnetic block. The lower pressing force acting on the lower pressing block can be transmitted to the lower end of the top rod, and the strong magnetic block can be separated from the workpiece. The specific use method is described below.

[0039] The installation of the protective plate, in order to prevent hand or hand, in the front and rear of the handle frame is provided with a protective plate 400, specifically, the protective plate is three, one of which is horizontally installed on the lower frame of the handle frame, and the other two are vertically arranged and installed on the horizontal protective plate, and a few-shaped arrangement is formed between the three protective plates, which can protect the strong magnetic block and prevent the occurrence of accidental adsorption. Especially, the tool is placed in any position during work, which can effectively avoid unnecessary attraction with ferrous materials.

[0040] The use method of the present grabbing tool is as follows:

[0041] First, one hand holds the handle frame, and the strong magnetic block in the tool is close to the steel workpiece 00 to be grabbed, the magnetic attraction of the strong magnetic block is used to adsorb the steel workpiece 00, and the grabbing is realized, then the steel workpiece is carried to the position, and then the lower pressing block is pressed by the hand, the lower pressing block is pressed down, and the No. 1 and No. 2 ejector rods are driven to move, the lower ends of the two ejector rods directly act on the steel workpiece, and the steel workpiece is separated from the strong magnetic block, after the two are separated, the tool is quickly pulled out, and one operation is completed. The grabbing tool can be reused.

[0042] The present tool has its use range and limit, theoretically, the weight of the grabbed steel workpiece should be less than 80% of the adsorption force of the strong magnetic block, that is, it has sufficient safety margin, the material of the steel workpiece is steel or iron, and copper or aluminum cannot be used.

[0043] The magnetic field covered by the strong magnetic block in the embodiment has very high stability, which can effectively resist the interference of external environmental factors, which greatly improves the safety of the operating personnel, provides a solid guarantee for safe production, and effectively implements the core principle of safe production. Secondly, the use of the tool has very high convenience. It can fully, flexibly and conveniently meet the needs of various different work positions and production diversification. In different positions and production scenes, it can show its unique advantages. And safe bearing magnetic attraction magnet to meet different work requirements.

[0044] The above-described embodiments are only used to describe the preferred embodiments of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the present application made by those skilled in the art shall fall within the protection scope of the present application.
