An automatic machine for batch grinding of various chemical test pieces

Abstract

An automatic machine for grinding various chemical test pieces in batches, which is composed of a motor start control device, a horizontal reciprocating drive mechanism and a grinding mechanism. The horizontal reciprocating drive mechanism is as follows: an eccentric wheel is installed on the reduction motor shaft, the translation block is set on two guide rods, and the eccentric column of the eccentric wheel is movably inserted into the bar-shaped notch of the translation block. The test piece tray is set on the top of the translation block; the grinding mechanism is wrapped on the pressure plate by the foam pad in the inner village of the emery cloth, and then fixed by the elastic member. The pressure plate is pulled down and pressed tightly on the test piece tray by four tension springs. The invention has the advantages of simple operation, controllable force and time controllable grinding process on multiple test pieces at the same time, replaceable grinding mechanism, uniform surface roughness of the same group of test pieces after grinding, and has broad application prospects.

Description

technical field [0001] The invention relates to an automatic grinding machine, in particular to an automatic machine for grinding various chemical test pieces in batches. Background technique [0002] In modern chemical experiments, in order to test the performance of adhesives: the viscosity, corrosion, maximum tensile force, maximum shear force and other parameters of epoxy resin and various chemical raw materials, it is necessary to spread various chemical reagents such as adhesives evenly on the On the chemical test piece (stainless steel rectangular plate), after the test piece is bonded and cured, the mechanical performance test or other operations are performed. [0003] The applied adhesive often remains on the surface of the test piece after curing, and it is difficult to separate from the test piece; in addition, some active metal test pieces are easy to form oxide film on the surface. Remove surface residues or oxides. [0004] The thickness of the chemical adhe...

AI Technical Summary

Problems solved by technology

[0007] If one quality inspector grinds multiple test pieces or multiple different test pieces, it cannot fully guarantee the above-mentioned uniformity of each group of test pieces, which will lead to large errors in subsequent experiments and affect the test results.

[0008] Due to the fine workmanship and high price of the metal test piece, a test piece will be reused hundreds of times, and the test piece after many times of manual polishing is more difficult to have uniformity due to the cumulative effect of errors

[0009] After each experiment, the quality inspector will spend a lot of time and energy polishing the test piece, which greatly takes up the time required for the quality inspector to conduct in-depth analysis of the experimental data and hinders the improvement of work efficiency
