Description

Electrolytic grinding machine for container sealing head

The utility model belongs to a kind of mechanical engineering special process equipment, particularly a kind of vessel head electrolytic polishing lathe that is used for large-sized rotating curved face processing.

Usually adopt manual machinery to grind to large tracts of land stainless steel watch mirror polish in the prior art, the instrument that is adopted is electronic or pneumatic emery cloth wheel or abrasive band.This polishing tool, production efficiency is low, labour intensity is big and the polishing after surface smoothness not high, cause material to be bonded on the chamber wall easily, thereby influence quality of chemical products and production efficiency.In order to obtain higher surface smoothness, " electrolytic polishing composite polishing " new technology has appearred in the eighties in the world, promptly the mechanical friction effect of electrolysis and abrasive material is combined, it is anode with the workpiece, tool-electrode is a negative electrode, on tool-electrode, fixing the grinding-material of tape insulation, during work, the tool-electrode rotation, tool-electrode and workpiece are done relative motion simultaneously, and electrolyte is sent to the gap location of tool-electrode and workpiece with pump, energising then makes surface of the work generation electrochemical dissolution and generates a kind of passivating film that has insulating properties at surface of the work, under the effect of abrasive material, again passivating film is ground off, thereby make surface of the work obtain high fineness.But process equipment of the prior art can only be suitable for the processing that plane or bus are the surface of revolution of straight line, does not satisfy the needs of the processing of the large-sized rotating curved face that bus is a curve (as vessel head).

The purpose of this utility model is to overcome problems of the prior art, provide a kind of and be applicable to that the vessel head electrolysis of large-sized rotating curved face mirror finish grinds the lathe that rubs, realize that negative electrode and grinding tool lean on workpiece along the normal to a surface direction all the time in motion process, the end socket curved surface is implemented to follow the tracks of, thus the electrolytic abrasive polishing of realization vessel head.

The utility model is achieved in that it is with the rotating mechanism of the common horizontal machine tool head of a bed as the rotation of drive end socket, a chuck is installed on the output shaft of rotating mechanism, a pedestal is arranged on the right side of rotating mechanism axial location, the feed mechanism that can move on X and Y direction that is driven by two stepper motors is installed on the pedestal, on feed mechanism, fix a support arm, the left end of support arm connects a cursor that is driven by rotating shaft by stepper motor, be connected with the negative electrode that can rotate together with rotating shaft that drives by one-way cylinder and mechanical striping mechanism on the cursor respectively, during work, processed vessel head is contained on the chuck, rotate around horizontal axis, said three stepper motors are controlled by three coordinate microsystems, feed mechanism is pressed preset program at X, the Y plane moves along a curved path, cursor rotates around the shaft by preset program, negative electrode and mechanical striping mechanism are just in the horizontal bus motion of the drive lower edge of feed mechanism and cursor end socket like this, and lean on workpiece along the normal to a surface direction all the time, simultaneously, start electrolyte circulation means and between negative electrode and anode (workpiece), inject electrolyte, connect power supply, can finish the electrolytic abrasive polishing of whole end socket inwall.

The utility model advantage is simple in structure, as long as the common lathe that lands is just transformed and can be realized, because negative electrode and mechanical striping mechanism automatic bus along end socket under control of microcomputer moves and leans on workpiece along the surface normal direction all the time, when the curved surface local shape is irregular, can compensate automatically, make negative electrode and mechanical striping mechanism keep predetermined pressure with workpiece all the time, therefore can guarantee negative electrode and correct Working position and the grinding direction of grinding tool in the process of processing, be specially adapted to the not too electrolytic abrasive polishing of the large-sized rotating curved face of rule of bumped head and geometry.

The utility model is elaborated and embodiment is provided below in conjunction with accompanying drawing:
