Description

Anti-collision and pressure-adjustable grinding and polishing integrated machine Technical Field The invention relates to the technical field of processing equipment for ceramic parts and products, in particular to a grinding and polishing integrated machine which is capable of preventing a grinding and polishing head from excessively striking a ceramic part and adjusting pressure acting on the ceramic part. Background The grinding polisher is used for improving the surface precision of the ceramic workpiece, and generally, after the ceramic workpiece is ground, polishing treatment is carried out to further improve the surface precision of the ceramic workpiece, and the ground and polished surface of the ceramic workpiece almost can reach the mirror finish. In the past, when the grinding and polishing treatment is carried out on ceramic parts, the grinding and polishing treatment is divided into two modes of manual processing and mechanical processing. Ceramic articles have the property of being hard and brittle and are susceptible to breakage when subjected to impact or pressure. During the process of processing ceramic parts, the grinding and polishing heads of the grinding and polishing machine need to be pressed on the ceramic parts all the time, and a hard contact relationship is formed between the grinding and polishing heads. The pressure of the grinding and polishing head acting on the ceramic part is instantaneously increased along with the instantaneous change of the processing feed quantity, the pressure applied to the ceramic part during the process is easy to damage the ceramic time, and the phenomenon similar to the phenomenon that the grinding and polishing head impacts on the surface of the ceramic part is also generated when the feed quantity is large, so that local cracks are easy to cause and even the ceramic part is guaranteed in cost. Disclosure of Invention Aiming at the problem that the ceramic workpiece is easily damaged when the ceramic workpiece is processed because the contact formed between the grinding and polishing head and the ceramic workpiece is in a hard contact relationship in the prior ceramic grinding and polishing machine, the invention provides an anti-collision and pressure-adjustable grinding and polishing integrated machine, wherein the contact between the grinding and polishing head and the ceramic workpiece is in adjustable flexible contact, which is beneficial to solving the problem that the grinding and polishing head is easily damaged when the feeding amount of the grinding and polishing head suddenly changes greatly in an instant. The invention solves the technical problems by adopting the technical scheme that the anti-collision and pressure-adjustable grinding and polishing integrated machine comprises a machine shell, a grinding and polishing disc and a grinding and polishing head. The grinding and polishing disc is arranged on the table top of the machine shell, and a motor a for driving the grinding and polishing disc to rotate is arranged at the lower part of the machine shell. The table top of the shell is provided with a pair of arm plates, a screw rod transmission mechanism matched with the motor b is arranged between the pair of arm plates, and the screw rod transmission mechanism can drive the first sliding seat to horizontally reciprocate in the left-right direction. The end face of the first sliding seat, which faces the polishing disc, is fixedly provided with a connecting seat, a screw rod transmission mechanism matched with the motor c is arranged on the connecting seat, and the screw rod transmission mechanism can drive the second sliding seat to reciprocate in the vertical direction. An assembling seat is fixedly arranged on the end face, facing the polishing disc, of the second sliding seat, and a motor d is arranged on the upper portion of the assembling seat and matched with the polishing head. And a rotating shaft is matched with the end part of the output shaft of the motor d, and the lower end of the rotating shaft is matched with the buffer assembly. The lower portion of the buffer assembly mates with the abrasive polishing head. The buffer assembly comprises a spring which is axially arranged along the vertical direction in an extending way, so that the buffer assembly can give the buffer amount or buffer space to the polishing head in the vertical direction. Through predetermining the elasticity size that the spring applyed on the grinding and polishing head, can be when the interaction pressure that forms between grinding and polishing head and ceramic finished piece is greater than predetermineeing elasticity, through the shrinkage deformation of spring, avoid grinding and polishing head to applys the excessive moment action pressure on ceramic finished piece, and then realize avoiding causing the problem of ceramic parts damage. The buffer assembly is used for relieving the force of the grinding and polishing disc on the buffer as
