Description

Technical Field

[0002] When processing wear-resistant cast balls, clamping and fixing are rather complicated.

[0003] The main reason is that during the processing of the wear-resistant cast ball, it needs to be clamped by a clamping device to achieve a fixed effect. However, before clamping, it usually requires the cooperation of two people to clamp the wear-resistant cast ball. One worker places the cast ball in the clamping position, and the other worker adjusts the clamping device to achieve the clamping effect. The operation of placing the cast ball and moving the clamping end by one person is difficult to achieve and has poor safety. It is easy to clamp the worker's hand when placing the cast ball, causing a safety hazard. Therefore, the clamping work of the cast ball needs to be simplified. Utility Model Content

Similarly, after completing the processing of the wear-resistant cast ball, the fixed clamping frame 6 and the movable clamping frame 4 are separated from each other, and the electromagnetic end head 7 adsorbs the wear-resistant cast ball to prevent it from falling off.

[0018] Furthermore, one end of the spring 72 is fixedly connected to the electromagnetic end head 7, and the other end of the spring 72 is fixedly connected to the outer tube of the telescopic tube 71. The spring 72 helps the telescopic tube 71 to rebound after being compressed.

[0020] Furthermore, the opening directions between the movable clamping frame 4 and the fixed clamping frame 6 are opposite, and the electromagnetic end head 7 is located at the center inside the fixed clamping frame 6, so as to keep the electromagnetic end head 7 adsorbing the wear-resistant cast ball at the center.

[0021] Furthermore, the electromagnetic terminal 7 is electrically connected to an electromagnetic switch below via an electric wire, and the electromagnetic switch controls whether the electromagnetic terminal 7 has adsorption force.

[0022] Working principle: The utility model is a wear-resistant cast ball clamp, which energizes the electromagnetic end 7 through the electromagnetic switch, and the electromagnetic end 7 generates magnetic force to adsorb the wear-resistant cast ball, performs preliminary positioning of the wear-resistant cast ball, and rotates the external rocker 3 again.
