Clamping device and clamping method

Abstract

The invention relates to a clamping device and a clamping method, and belongs to the field of inspection of the industries of metallurgy, minerals, electric power and the like. The clamping device comprises a fixing support, a force applicator, a fixed claw and a movable claw; the force applicator, the fixed claw and the movable claw are all connected with the fixing support in a matching mode; and the force applicator provides power so that objects can be clamped by the fixed claw and the movable claw. The clamping device is convenient to use, and can stably and tightly clamp the objects.

Description

technical field [0001] The application relates to the field of inspection in metallurgy, mining, electric power and other industries, and to the field of inspection in the iron and steel metallurgy industry, in particular to a clamping device and a clamping method for a grinding machine to clamp a grinding core in a grinding bowl. Background technique [0002] In the process of incoming inspection of bulk raw materials such as iron ore, coal, coke, ferroalloy and flux ore, sample preparation is involved. The process of sample preparation cannot be done without the step of grinding with a grinder. [0003] The core part of the grinder - the grinding bowl - is mainly composed of a grinding disc, a grinding ring, and a grinding core. The sample grinding method mainly uses the grinding core and the grinding ring in the grinding bowl of the grinder to relatively high-speed centrifugally rotate and pulverize the sample. [0004] At present, after using a grinder to grind a sampl...

AI Technical Summary

Problems solved by technology

[0006] 1. The process of taking out the grinding core and grinding ring with bare hands is easy to touch the sample and pollute the sample, which affects the quality of subsequent sample testing (especially when it comes to coal samples that enter the factory for settlement, the addition of fine particles and debris will cause fluctuations in the quality of sample testing, cause quality objections);

[0007] 2. After the grinder grinds the sample for many times, the high-speed rotating grinding core and grinding ring accumulate a lot of heat. Contacting it with bare hands is very likely to cause safety accidents such as burnt fingers or high-altitude injuries, and it is also easy to put the grinding bowl Sample samples knocked over and scattered
