Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a double-layer vertical and horizontal machining center machine tool. Background technique [0002] At present, in order to ensure that the workpiece can be processed as many surfaces as possible and multiple surfaces at the same time when the workpiece is clamped at one time, the processing efficiency can be improved, the auxiliary processing time can be reduced, and the same function and processing range of the machine tool can be guaranteed. The ground area is as small as possible. In order to solve this problem, some machine tool manufacturers use vertical machining center machine tools, which are composed of bases, rams, worktables, columns, spindle boxes and CNC units for controlling the work of various components of CNC machine tools. The upper end of the base is provided with a ram and a column, the lower end of the ram is slidably connected by the slide rai...

Problems solved by technology

[0002] At present, in order to ensure that the workpiece can be processed as many surfaces as possible and multiple surfaces at the same time when the workpiece is clamped at one time, the processing efficiency can be improved, the auxiliary processing time can be reduced, and the same function and processing range of the machine tool can be guaranteed. The ground area is as small as possible. In order to solve this problem, some machine tool manufacturers use vertical machining center machine tools, which are composed of bases, rams, worktables, columns, spindle boxes and CNC units for controlling the work of various components of CNC machine tools. The upper end of the base is provided with a ram and a column, the lower end of the ram is slidably connected by the slide rail and the base provided on the bed, and is driven by the screw provided on the base to slide horizontally along the Z axis. The slide rail is slidingly connected with the ram, and is driven by the screw provided on the ram to slide horizontally along the X-axis. There is a guide rail on one side of the column, and a spindle box is provided on the guide rail, and the spindle box passes through the screw provided on the column. The driver slides vertically up and down along the guide rail. The lower end of the spindle box is facing the workbench with a spindle head, and the upper end of the spindle box is equipped with a servo motor. The servo motor drives the spindle head to rotate, and then the parts are processed. The disadvantage is: during the processing , it is necessary to repeatedly change the positioning state of the workpiece on the workbench, prolong the processing time of the workpiece, reduce the production efficiency, and increase the labor intensity of the workers; Table, lifting screw, spindle box and CNC unit for controlling the work of various parts of the CNC machine tool. There is a worktable on the base, a column at one end, and a screw for driving the horizontal sliding of the column on the base. The worktable The upper part is equipped with a rotary table, which can realize the workpiece to rotate ±360° along the Z axis. The rotating body of the main shaft rotates ±90° to realize the dual-purpose of the main shaft, so as to process multiple surfaces of the workpiece. The disadvantage is that it is necessary to change the position of the rotating body of the main shaft to process multiple surfaces of the workpiece one by one, and the processing time is long. Low production efficiency; there is another kind of machine tool with multi-milling head machining center to process multiple surfaces at the same time, and use the exchange table device to process workpieces to reduce processing auxiliary time. The disadvantages are: high cost of machine tools and large floor space
