Automatic polishing device for paint film abrader grinding wheel

Abstract

The invention relates to the technical field of polishing, in particular to an automatic polishing device for a paint film abrader grinding wheel. The device comprises a base, a workbench is mounted on the upper sides of a first guide sliding rail and a second guide sliding rail, a transverse moving bearing seat is mounted on the outer walls of a transverse moving screw rod and a transverse movingguide rod, a lifting mounting table is mounted on the outer walls of a lifting screw rod and a vertical guide rod, a polishing head is mounted on the lower side of the front face of the lifting mounting table, a driving seat is arranged on the left side of a base surface of the workbench, a polishing motor corresponding to a first driving shaft is mounted on the base surface of the workbench, a clamping fixing rod is rotatably mounted on the upper side of a sliding seat, and a grinding wheel mounting shaft seat is mounted at the end, far away from the driving seat, of a second driving shaft.Through the polishing device, manual operation is adopted only when the grinding wheel is mounted, mechanical automatic control is adopted for other operations, the work efficiency is improved, and meanwhile safety in the polishing process is high.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to an automatic grinding device for a grinding wheel of a paint film abrasion instrument. Background technique [0002] In daily life, wear phenomenon is very common. There are many physical, chemical and mechanical reasons for this phenomenon, mainly abrasive wear, adhesive wear (gluing), fatigue wear (pitting corrosion), and corrosive wear. Wear resistance is related to almost all properties of materials, and under different wear mechanism conditions, there are different requirements for material properties in order to improve wear resistance. Due to the different friction materials and test conditions, it can be expressed by the wear index or the material loss (g / cm2) measured by the wear tester under the specified conditions, or its reciprocal. The wear resistance is the friction and wear A measured variable in an experiment. Abrasion resistance in the coatings industry refer...

AI Technical Summary

Problems solved by technology

A paint film abrasion tester is usually used to measure the wear resistance of the paint film, that is, under a certain load, after the paint film is polished with a rubber grinding wheel at a specified number of revolutions, the weight loss of the paint film is obtained, expressed in grams, in actual use At the same time, the rubber grinding wheel of the paint film abrasion tester needs to be polished regularly, but the existing grinding devices often require manual operation, the degree of automation is low, and there are large safety hazards. Therefore, an automatic grinding wheel for the paint film wear tester is needed The device improves the above problems
