Abstract

The machine is designed with its conceptual solution for incorporation into an automatic line manufacturing system with a manipulator or robot. It is made up of a swivel adit fitted with full automatic rotary clamps for simultaneous clamping two, counter-oriented workpieces from a vertical milling workstation from the required number of horizontal vertical or oblique work stations and a control station equipped swiveling ridge for shooting clamps at the feed control workstation.

Description

(54) Automatic machine for machining workpieces by initial operations

With its conceptual design, the machine is designed to be integrated into an automated production system line with manipulator or robot operation. It consists of a swivel shaft fitted with full automatic swivel clamps for the simultaneous clamping of two, counter-oriented workpieces, a vertical workstation with a milling headstock from the required number of horizontal, vertical or inclined workstations and a control station equipped with a swivel rack for swiveling workstation.

The invention relates to the concept of a full automatic high-performance bending machine for machining workpieces from at least two sides, namely for straightening fronts, drilling center holes, surface turning and other operations, including controlling the execution of all operations. The machine is designed for integration into lines of automatic production systems with manipulator or robot operation.

The most powerful machines of this design are made up of a number of counter-rotating horizontal and vertical workstations with a rectilinear workpiece conveyor between stations arranged in an endless belt, with spring-loaded workpieces and hydraulic clamping in working positions. Straight chip conveyors are built on both sides of the conveyor. These machines are equipped with workpiece magazines and can also be equipped with manipulators.

A machine tool for machining workpieces by initial operations according to the invention is intended for full automatic operation in lines of automatic manufacturing systems operated by a manipulator or a robot. It is made up of a rotary shaft equipped with full automatic rotary clamps for the simultaneous clamping of two, counter-oriented workpieces, a vertical workstation with a self-drive milling headstock and a retractable and rigid piool device and a control workstation equipped with a rotary play turning the clamps when the control workstation is moved backwards. In addition, the machines include the required number of horizontal, vertical or inclined workstations.

Such a conceptual arrangement of the machine according to the invention summarizes the advantages of the known machine concepts and furthermore benefits the workpiece transport system in the fixtures as well as the handling of the workpiece replacement by utilizing a proven modular swivel gallery element, particularly beneficial in terms of complete machine automation. The concept of full automatic rotary clamps for the simultaneous clamping of two, counter-oriented workpieces allows the use of each workstation to simultaneously machine the opposite ends of both workpieces. Therefore, each operating head is equipped with two tool groups. The milling head of a vertical station covers the diameter of the tool with both workpieces, which is advantageous in terms of both economical use and tool life because it is equipped with a large number of cutting edges. To complete the machining of its two sides, each workpiece on the turntable undergoes two turns, but with respect to the simultaneous clamping of two workpieces in each clamping, the manipulator removes one complete machined workpiece from both or more sides from the respective fixture. This results in high machine performance.

An example of a conceptual machine arrangement is shown in FIG. 1, which is a plan view thereof and FIG. 2 is a perspective view thereof.

The automatic machine for machining workpieces by the initial operations according to the invention consists of a rotary table 6 with automatically rotatable clamps 7, a vertical work station 1 with a self-drive milling head 2 and a withdrawable and reinforcing device 12 of the quill 11, and the required number of horizontal, vertical or inclined work stations 3, 4, 5 and from a control station 8 equipped with a rotating rack 15 for pivoting the clamps 7 when the control work station 8 is moved backwards. The automatic rotary clamps 7 are automatically released by turning the rotary table 6 to position 10. and by moving to the next position of the pivot shaft 6, they clamp.

The function of an automatic machine for machining workpieces by initial operations according to the invention proceeds as follows:

The manipulator inserts the workpiece 9 into the corresponding, automatically released chuck 7, after turning the pivot shaft 6 to position 10. Gradually, all the chucks 7 on the turntable S are filled one workpiece 9. of its operating heads, including the inspection operations by the inspection station 8, which rotates the respective clamp 7 by 180 ° in the wrong movement. Thereby, the workpiece 9 is rotated with an untreated end to the workstation tools 1, 3, 4, 5 and the clamp 7 with its unoccupied part to insert a new unworked workpiece 9. 4, 5 carry out work operations. After further rotation of the clamps 7 by 180 °, the machine performs its regular duty cycle in which, in position 10, the manipulator removes the fully machined workpiece 9 from the automatically released clamp 7 and inserts the workpiece 9 unworked.

Automatic machine for machining workpieces by initial operations, namely for any kind of operation, after the workstations are fitted with the respective operating heads. The machine is especially suitable for robotized workplaces where high performance and machining of workpieces from at least two sides is required.
