Vertical Machining Center + Horizontal Machining Center A New Machine Tool was Born

At present, in order to ensure that the workpiece is machined as many times as possible, and multiple faces are processed as much as possible, the machining efficiency is improved, the machining assist time is reduced, and the same function and processing range of the machine tool are ensured. In order to solve this problem, some machine tool manufacturers use vertical machining center machine tools, which consist of a base, a ram, a work table, a column, a headstock, and a numerical control unit for controlling the work of various parts of the CNC machine tool. The upper end of the base is provided with a ram and a column, and the lower end of the ram is slidably connected via a sliding rail rain base provided on the bed body, and is horizontally slid along the Z axis through a screw provided on the base, and the working table is provided through the upper part of the ram The slide rail is slidingly connected to the ram.

 

And the screw drive provided on the ram is horizontally slid along the X-axis, and a guide rail is arranged on one side of the column, and a spindle box is arranged on the guide rail, and the spindle box is driven to slide vertically along the guide rail through the screw rod provided on the column, the spindle The lower end of the box is provided with a spindle head on the workbench. The upper end of the spindle box is provided with a servo motor. The servo motor drives the spindle head to rotate, and then the parts are processed. The disadvantage is that the workpiece is repeatedly changed on the workbench during the machining process. The positioning state, prolonging the processing time of the workpiece, the production efficiency is low, and increasing the labor intensity of the workers; some adopt a five-axis linkage machining center machine tool, which is composed of a base, a column, a work table, a rotary table, a lifting screw, a headstock, and The numerical control unit is used for controlling the working of various parts of the numerical control machine tool. The base is provided with a workbench, one end is provided with a column, the base is provided with a lead screw for driving the horizontal sliding of the column, and the upper part of the worktable is provided with a rotary table, which can be realized. The workpiece rotates ±360° along the Z axis, and the headstock is provided on the column. The spindle box is driven by the lead screw provided on the column to slide down along the guide rail on the column. The box adopts a spindle revolving body that can be rotated ±90° to realize the vertical and horizontal use of the main shaft to achieve multiple faces of the workpiece. The disadvantage is that the position of the main shaft revolving body needs to be changed to machine multiple faces of the workpiece one by one. Long time, low production efficiency; another is to use multiple milling head machining center machine to machine multiple faces at the same time, and use the exchange table device to process the workpiece to reduce the machining auxiliary time. The disadvantage is: high machine cost and land occupation large area.

 

Double vertical machining center machine

In order to ensure that the workpiece is machined at the same time as many times as possible, the advantages of the vertical machining center machine and the horizontal machining center machine tool are combined to realize that the vertical milling head and the horizontal milling head simultaneously process the same workpiece. It can process five faces in one clamping, a double-layer vertical horizontal machining center machine with novel structure, convenient and quick operation, reduced processing auxiliary time, improved production efficiency and reduced floor space.

 

The utility model comprises a base, a column, a driving screw, a spindle box and a numerical control unit for controlling the working of the numerical control components. The spindle head is provided with a spindle head at one end and a servo motor at the other end, and the fixed column and the movable column are arranged on the base. , the upper workbench device and the lower workbench device, the lower workbench device is arranged on the base, and the lower end of the carriage in the lower workbench device is connected with the base through the lower drive screw, and is driven by the lower drive screw to make the lower workbench The device travels along the X-axis of the screw rod, and the front and rear brackets are respectively arranged on the front and the rear sides of the lower table device, and the movable column and the fixed column are respectively arranged on the left and right sides.

 

The lower ends of the front bracket and the rear bracket are respectively fixedly connected with the base, and the upper end is slidably connected to the carriage in the upper workbench device via the guide rail, and the two ends of the carriage in the upper workbench device and the drive screw provided on the front bracket and the rear bracket The hinge is driven by the driving screw to slide the upper table device along the X-axis direction, and the fixed column is fixedly connected with the base. The movable column is connected to the base via a driving screw fixed on the base, and is driven by the driving screw. , the movable column is driven along the X-axis of the driving screw, and the horizontal column box is arranged on the movable column.

 

The horizontal spindle box is slidably connected to the movable column via a vertical drive screw fixed on the movable column, and is driven to slide along the Y-axis by a vertical drive screw drive. The fixed column has a vertical spindle box, and the vertical spindle box is The vertical drive screw fixed on the fixed column is slidably connected with the fixed column, and is driven by the vertical drive screw to drive the Y-axis direction. The vertical machining center machine and the horizontal machining center machine are integrated, and the upper and lower working platforms are shared. , reducing the floor space, reducing the processing aid time and improving work efficiency.

 

The upper workbench device and the lower workbench device are respectively composed of a workbench body, a rotary workbench, a turbine, a worm, a servo motor, a carriage, a drive screw and a guide rail. The middle of the carriage is a hollow cavity, and the inner side of the cavity is along the Z The guide rail is arranged in the axial direction, the upper end of the guide rail is provided with a driving screw, the driving screw is in the same direction as the guide rail, the lower end of the working platform body is slidably connected with the guide rail, the upper end sides are hinged with the driving screw rod, and a trapezoidal groove is arranged in the middle, and the rotating work is performed. The table is arranged in the trapezoidal groove, the lower end of the rotary table is provided with a turbine, and the turbine is meshed with the servo motor fixed on the worktable body through the worm, and is driven by the servo motor to cause the worm to drive the rotary table to rotate, and drive the screw Drive to slide the table body along the Z axis to facilitate milling of the four faces of the workpiece by the horizontal spindle milling head. The vertical milling head and the horizontal milling head can simultaneously process the same workpiece, and can process five faces in one clamping.
