Grinding wheel sand blasting hardness machine

Abstract

The invention provides a grinding wheel sand blasting hardness machine which comprises a lower extrusion plate, a hopper, a supporting frame, an upper extrusion plate, a weighing hopper and a sand blasting assembly, a quantitative discharging assembly is arranged at the bottom of the hopper and used for achieving quantitative discharging, the supporting frame is arranged on the lower extrusion plate through a linear guide pair, and the upper extrusion plate is movably installed on the supporting frame; wherein an extrusion gap is formed between the upper extrusion plate and the lower extrusion plate, a reciprocating driving assembly is arranged between the supporting frame and the upper extrusion plate and used for driving the upper extrusion plate to ascend and descend in a reciprocating mode, a feeding port of the weighing hopper is located below the end of the upper extrusion plate, and the sand blasting assembly is located at the bottom of a discharging port of the weighing hopper. Materials are extruded and conveyed through the upper extrusion plate and the lower extrusion plate, then hardened materials are thoroughly scattered, the upper extrusion plate reciprocates and translates along the lower extrusion plate in a reciprocating mode, the materials can be quantitatively conveyed on the premise that the materials are extruded, and the hardness requirement of sand blasting is met.

Description

technical field [0001] The invention relates to the technical field of grinding wheel processing, in particular to a grinding wheel sandblasting hardness machine. Background technique [0002] Ordinary grinding wheels are composed of abrasives and binders, and hardness is an important parameter in the selection and use of grinding wheels. If the hardness of the grinding wheel is relatively hard relative to the needs of the workpiece, it will cause the self-sharpening of the grinding wheel to deteriorate, the grinding efficiency will decrease, the grinding quality will decrease, and even the workpiece will be burned; if the hardness of the grinding wheel is softer than the workpiece needs, the grinding wheel will consume fast, affecting the machining accuracy. The sandblasting hardness machine is a special equipment for testing the hardness of the grinding wheel. Its working principle is that the quartz sand of a certain particle size and volume is driven by a certain pressu...

Problems solved by technology

[0003] The publication number is CN206095841U, which provides an accurate and stable grinding wheel sandblasting hardness machine. This prior art performs sandblasting by quantitatively weighing materials, but the materials will harden during the long-term accumulation process, and then harden. After the material enters the nozzle, it will not affect the sandblasting effect

[0004] Publication No. CN206974800U provides a feeding device for a grinding wheel sandblasting hardness machine. This prior art discloses a solution for processing hardened materials, but this prior art uses a rotating stirring rod to break up hardened materials. , although this method can achieve the effect of breaking up the material, but the material cannot be guaranteed to be in contact with the executive part of the stirring rod when it is conveyed, and then there will be a situation where the hardened material is not broken up, which will affect the sandblasting effect
