Description

MULTI-SPEED MILLING MACHINE

The invention relates to machine tools, namely to milling machines and can be used in the processing of milling flat and curved surfaces, in particular, in the manufacture of printing plates, stamps, dies, etc.

Known multi-spindle copy-milling machine, containing; base, desktop, spindles with a working tool (1). The well-known milling machine provides processing of the product in two planes due to simultaneous horizontal mixing, working table in one direction and mixing; spindles along the copiers in two directions, perpendicular to the direction of the working table, which allows you to process three-dimensional surfaces. Shuffling; spindles are associated with shuffling the desktop, which limits the set of surfaces obtained. In addition, the shape of the surface to be machined is determined by the shape and location of the copy lines. Since the range of carbon lines is limited, processing options are also limited.

The SM-600 F4 milling machine (2) is known, it contains a base, a coordinate table, electric spindles with a working tool, a numerical control system (CNC) by mixing, a coordinate table by two mutually perpendicular coordinates in the horizontal plane and vertical displacement1; spindles, chip suction system. The well-known machine also allows you to process three-dimensional surfaces. Since the workpiece is mixed in any of the three coordinates

independently of each other, the machine allows you to get an infinite number of forms of machined surfaces. In addition, equipping the machine with a CNC system, unlike a set of copy lines, allows you to specify the processing of an infinite number of surfaces using a programmed method. The workpieces are fixed on the coordinate table using pins pre-installed in the workpiece and pneumatic clamps. Such fastening of the workpieces requires preliminary processing of the workpiece, pressing pins into it, which reduces the productivity of the work process. The chip extraction system works simultaneously for all spindles. In the case of processing with fewer spindles, energy costs are irrational.

The technical result of the invention is to increase the productivity of the workflow, reduce energy costs and increase the convenience and ease of fixing the workpiece on the desktop.

The specified technical result is achieved by the fact that in a multi-spindle milling machine containing a base, a portal rigidly fixed to the base, a coordinate table mounted on the base, electric spindles with a working tool installed on the portal, a system of numerical program control of the movement of the coordinate table in two mutually perpendicular the coordinates in the horizontal plane and the vertical movement of the electric spindles, a chip removal system consisting of a chip removal device, pipes wires and a collector on the work surface coordinate table mounted vacuum table with two independent vacuum cavity connected by vacuum piping to a vacuum pump, the vacuum lines are provided with shut-off devices, and each of the pipelines chip removal system is also provided with a locking device.

introducing into the device a vacuum table connected by pipelines to a vacuum system. The presence of a vacuum table eliminates the preliminary preparation of the workpiece for mounting on the desktop, which reduces the time for preparation for work. The workpiece is placed on a vacuum table and, after turning on the vacuum system, is firmly fixed on it, which makes the process of installing the workpiece simple and convenient.

Energy costs are reduced by disconnecting the chip suction system from idle electrospindles using shut-off devices located on each of the suction system pipelines.

The multi-spindle milling machine of the invention is shown in FIG. 1 and 2, wherein in FIG. 1 shows a General view, figure 2 is a side view, where:

The multi-spindle milling machine (Fig. 1,2) contains a base 1, on which the portal 2 is rigidly fixed. On the base 1 there is also a coordinate table 3, which can be moved along two mutually perpendicular coordinates. Table movement is carried out using linear electric motors 4 and 5 on aerostatic bearings, providing movement along the X and Y coordinates, respectively. On the portal 2, electric spindles 6 with a working tool 7 are installed, also having the possibility of vertical movement along the Z coordinate using linear electric motors 8 on aerostatic supports. The movement of the coordinate table and the electric spindles is controlled by the CNC system 9. The machine is equipped with a chip removal system consisting of a chip-removing device 10, pipelines 11 and a manifold 12. The pipelines 11 are equipped with locking devices 17. A vacuum table 13 with two independent cavities 14 is installed on the working surface of the coordinate table 3 The vacuum cavities are connected by vacuum pipelines 15 to a vacuum pump 16. Vacuum pipelines 15 are also provided with shut-off devices 17. Shut-off devices can be made in the form of hand cranes. The presence of two independent cavities in the vacuum table, independently connected by vacuum pipelines to the vacuum pump, allows the processing of small workpieces on only one half of the table. Disabling idle spindles in such a situation leads to energy savings.

Multi-spindle milling machine operates as follows. The workpiece 18 is placed on the vacuum table 13, after which the vacuum pump 16 is turned on. However, if the workpiece is smaller than half the table, then only one vacuum cavity 14 is connected to the vacuum pump using the locking device 17. The vacuum created by the vacuum pump 16 in the vacuum cavity 14, allows you to quickly, simply and at the same time securely mount the workpiece on a vacuum

table 13. Depending on the size of the workpiece, the number of electrospindles for its processing may be different. Electrospindles can process one large workpiece in series, each in its own zone and according to its individual program. It is also possible to simultaneously process several identical workpieces with several electrospindles according to the same program. You control and implement the programs with the help of the CNC system. Manage; programs can be designed to handle various types of products: printing cliches, matrices, volume stamps.

After setting the workpiece, the processing program for the corresponding workpiece is turned on. In the event that processing is not performed by all electrospindles, the piping 11 of the chip removal system, connecting 1, the chip-removing system; its device 10 is idle; they are electrically spindled, are closed by shut-off devices 17. Shut-off devices 17 can be made in the form of taps. The locking devices are controlled by the operator before or during the processing of the workpiece.

Thus, the device according to the invention allows to increase the productivity of the workflow, reduce energy costs and increase the convenience and ease of fixing the workpiece on the desktop.
