The working angle adjusting system of the four-set angle grinder can enable the lower connecting plate to incline to a certain extent through screwing and unscrewing of different adjusting nuts and bolts II, so that the angle grinder can incline to a certain extent, and further the contact position of the working part (grinding wheel and polishing piece) of the angle grinder and the surface to be processed of the part is changed, and therefore the processing treatment of the surfaces to be processed of different shapes and styles is realized.
The first spring in the angle grinder working angle adjusting system and the second spring in the angle grinder height adjusting system play an important role in the working process, firstly, the respective bolts and nuts are not easy to fall off, the current position of the connecting plate is maintained through the tensioning state, the structural strength of the mechanism is improved, the stable state is maintained in the working process, and the working stability is ensured. Secondly, when the angle grinder encounters a boss, a welding line and the like and receives upward extrusion force and is transmitted to the connecting plate, the first spring and the second spring can obtain a damping and buffering effect, so that the angle grinder can generate upward displacement, the impact on the whole angle grinder is reduced, and damage or burning caused by rigid collision is avoided. And after passing through the high platform, the angle grinder can be restored to the initial working position by the tensioning force of the first spring and the second spring.
When the angle grinder works, the working angle adjusting system of the angle grinder and the height adjusting system of the angle grinder are not in the limiting positions, but extrusion is generated, namely the nut and the adjusting nut leave the contact surface, so that the first spring and the second spring are further compressed, the angle grinder can continuously receive downward extrusion force, and when the surface shape of the steps is processed, after the steps are slightly lowered for one time, the angle grinder can be pushed to be downward under the tensioning action of the first spring and the second spring, so that the steps are further processed. Through the first spring and the second spring, the damping, buffering and recovering functions are effectively achieved, and the angle grinder can continuously receive downward force, so that manual forced downward pressing is avoided, and labor intensity is further reduced.
When one row of processing on the surface of the part is completed and the part needs to be transferred to the next row, unscrewing the front guide rail seat stop bolt and the rear guide rail seat stop bolt, moving the guide rail, placing the whole machine on the guide rail, simultaneously moving to the next working area, screwing the front guide rail seat stop bolt and the rear guide rail seat stop bolt, and carrying out the next processing.
When the grinding and polishing device is used, the angle grinder is subjected to downward pressure given by the first spring and the second spring in the clamping mechanism, so that a user does not need to press downwards, and the user only needs to push the whole machine to move forwards and backwards through the handle.
The present invention is not limited to the above embodiments, and any person who can learn the structural changes made under the teaching of the present invention can fall within the scope of the present invention if the present invention has the same or similar technical solutions.
The technology, shape, and construction parts of the present invention, which are not described in detail, are known in the art.
