Metallographic phase polishing solution automatic feeding machine

Abstract

The invention provides a metallographic phase polishing solution automatic feeding machine which is used for grinding and polishing of metallographic specimens. The metallographic phase polishing solution automatic feeding machine is formed by a stirring motor, a liquid storage cylinder, a stirring shaft, blades, a liquid pump motor, a plunger liquid pump, check valves, connecting ducts, a nozzle and a single-chip microcomputer. The metallographic phase polishing solution automatic feeding machine is characterized in that the stirring motor is installed on the upper portion of the liquid storage cylinder, the output end of the stirring motor is connected with the stirring shaft, the blades are installed at the lower end of the stirring shaft, the output end of the liquid pump motor is connected with a cam, the cam is connected with the piston of the plunger liquid pump, the cylinder block of the plunger liquid pump is connected with the liquid storage cylinder and a liquid outlet end nozzle respectively through the ducts, and check valves are respectively arranged on the ducts at two ends of the plunger liquid pump to control liquid to flow only along a single direction. The metallographic phase polishing solution automatic feeding machine has the advantages of being accurate in liquid outlet quantity, capable of setting liquid outlet time intervals, high in degree of automation, and capable of achieving the switching usage between an automatic function and a manual function according to different operation requirements.

Description

technical field [0001] The invention relates to a metallographic sample preparation device, in particular to an automatic metallographic polishing liquid supply machine for grinding and polishing metallographic samples. Background technique [0002] With its unparalleled high hardness and excellent mechanical properties, diamond has become the best abrasive for metallographic sample preparation. It is suitable for grinding and polishing of metallographic samples. At present, many domestic units use diamond grinding paste, or use pressure-resistant containers to make grinding sprays. In the process of using these two products, spray cans must be held in hand, which is inconvenient to operate, and also has the following problems in addition. [0003] a) Disadvantages of grinding paste. [0004] 1. The amount of polishing paste in the fabric fiber gap is small, and it is lost with the operation of the turntable of the polishing machine and the throwing liquid. [0005] 2. ...

AI Technical Summary

Problems solved by technology

[0004] 1. The amount of polishing paste in the fabric fiber gap is small, and it will be lost with the operation of the turntable of the polishing machine and the throwing liquid flow

[0005] 2. The oily substance in the abrasive paste adheres to the surface of the sample, affecting the turbidity quality of the sample

[0007] 1. Propellant is used in the product, the price is higher

[0008] 2. The propellant only plays the role of taking the abrasive liquid out of the tank, does not participate in the grinding, and has a certain pressure, which makes the produc
