7-shaft 4-spindle polishing engraving milling machining center

Abstract

The invention discloses a 7-shaft 4-spindle polishing engraving milling machining center. The machining center comprises a base, a shell, a protective cover, a water tank, windows, electric control box doors, a skylight, an electric box, a sliding door, a portal frame, a workbench, a storage drawer, a fixing plate, a second guide rail, a lead screw, a motor, a sliding block, a first spindle, a second spindle, a third spindle, a fourth spindle and a control box, wherein the shell is fixedly connected to the top of the base, the workbench is connected to the bottom of the inner wall of the shell, the windows are formed in the two sides of the shell correspondingly, the protective cover is fixedly connected to the bottom end of the side, perpendicular to the windows, of the shell, the electric box is arranged in the base, the water tank is fixedly connected to the side edge of the base, the electric control box doors are symmetrically arranged on the surface of the shell and located abovethe protective cover, and the skylight is arranged at the top of the shell. The polishing engraving milling machining center ensures the straightness and movement continuity of a machine tool movement mechanism, polishing machining can be carried out, and machining of other various procedures can also be carried out.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a 7-axis, 4-spindle pick light engraving and milling machining center. Background technique [0002] At present, the 3C industry not only has higher and higher requirements for the surface effect of metal casings (such as mobile phones, tablet computers, etc.), but also requires doubled efficiency with the intensification of industry competition, so as to reduce costs and make contemporary manufacturers profitable. , the multi-spindle pick light engraving and milling machining center has become the development trend of the industry. The pick light machining requires that no knife lines can be seen, so more stringent requirements are put forward for the machine tool that processes it, such as machine vibration, movement continuity, movement The straightness of the mechanism, the spindle speed, the circular runout and the full runout, etc., if any aspect exc...

Problems solved by technology

[0002] At present, the 3C industry not only has higher and higher requirements for the surface effect of metal casings (such as mobile phones, tablet computers, etc.), but also requires doubled efficiency with the intensification of industry competition, so as to reduce costs and make contemporary manufacturers profitable. , the multi-spindle pick light engraving and milling machining center has become the development trend of the industry. The pick light machining requires that no knife lines can be seen, so more stringent requirements are put forward for the machine tool that processes it, such as machine vibration, movement continuity, movement The straightness of the mechanism, the spindle speed, the circular runout and the full runout, etc., if any aspect exceeds the standard, the pick light effect will fail; and the multi-spindle pick light machine has multiple spindles working at the same time, and the vibration affects each other, so it is harmful to the machine. The stability of the platform puts forward more stringent requirements. At present, there is still a blank in the country for the equipment of pick light engraving and milling with automatic tool change. There are a few manufacturers with this kind of processing machine tools, but there is no tool magazine, the speed is very slow, and The problem of the mutual influence of the spindle is not well handled, the stability is not high, and only one process can be processed at a time, and other processes cannot be performed, such as engraving and milling, drilling, tapping and other processes. If you want to perform the above processing, It is necessary to manually change the tool, which delays the time and affects the accuracy of one clamping. Therefore, we propose a 7-axis 4-spindle pick light engraving and milling machining center
