Automation machine for batch-grinding various chemical test blocks

Abstract

The invention relates to an automation machine for batch-grinding various chemical test blocks. The automation machine consists of a motor start control device, a horizontal reciprocating driving mechanism and a grinding mechanism, wherein the horizontal reciprocating driving mechanism has a structure that an eccentric wheel is installed on a reducing motor shaft, a translational block is arranged on two guide rods in a sleeving manner, an eccentric column of the eccentric wheel is movably inserted into a strip-type slot of the translational block. A test piece tray is installed on the top of the translational block in a sleeving manner. The grinding mechanism is formed in a manner that abrasive cloth lined with a foam gasket wraps a pressure plate, and then the pressure plate is fixed by an elastic member. The pressure plate is pulled down and compressed on the test piece tray by using four tension springs. The automation machine provided by the invention is simple and convenient to operate and can be used for simultaneously controlling force and time of a plurality of test pieces. The grinding mechanism can be used for replacing grinding. The test pieces in a same group after grinding are uniform in surface roughness, so that the automation machine has a wide application prospect.

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
