Equipment For The Exchange Of Replaceable Components In Machine Tools

Abstract

The invention relates to equipment for the exchange of replaceable components in machine tools, specifically replaceable components of different categories, necessary for different machining operations, such as heads or tool holders and tools, comprising a unified static storage, in which said components are located, and a single piece of manipulating equipment (20) provided with at least one manipulator (50) for said components, automated and controlled by a control system, for the movement, exchange and positioning of the replaceable components of both types between the ram of the machine tool (10) and the storage (40).

Description

technical field [0001] As shown in the title, the present invention, a replacement device for replacing replaceable parts in a machine tool, relates to an automatic exchange device for different types of different parts (processing heads, tool holders and tools) in a machine tool. The purpose of this device is, in machine tools such as vertical lathes, to allow the exchange of various replaceable parts therein, whether they be heads, tool holders or tools. Said equipment consists essentially of a standard static store and a one-piece handling device for said parts, in which all different kinds of replaceable parts are stored, which is automatically operated and controlled by System control, the operating system has freedom of movement and has at least one manipulator with gripping devices for different kinds of replaceable parts, so that said manipulator can be positioned on the main axis of the machine tool or on the ram and above Move, replace and locate between mentioned r...

Problems solved by technology

However, it also has a disadvantage: it makes the weight hanging on the beam very large, which causes a loss of torque and consequently the precision of the machine

However, it also has disadvantages: the picker is not accessible from any position of the beam when the height of the part is greater than the stroke of the ram during machining; Stand-alone equipment of the rotary type; the process of changing the head of this system is long, the replacement time increases and when there are multiple heads, the floor space is large

[0009] - Circular rotary pick-up on the ground with a lifter: this system has the advantage of being accessible from any position on the beam, and when the It requires an additional vertical carousel-type stand-alone device when a large number of tools needs to be stored and changed

In addition, in tall machines, a large disc lifting stroke is required to achieve the change in the highest position of the beam, so the weight of the head and the tools stored are limited

[0010] - Carriage with translational movement on the ground: this system has the advantage that it is not limited to the number of heads nor to their weight, however, when the height of the part being processed is greater than the stroke of the ram, it will Not accessible from any position on the beam, moreover the knives require separate equipment of the type of other vertical carousel, involving large floor space when there are multiple heads

[0011] - fixed pickup on the ground, independent of each head: the system is unlimited in number, weight of heads and it has a relatively low manufacturing cost, but it also has a disadvantage: it requires additional axes to move the head towards each picker, in addition, when the height of the part being processed is greater than the stroke of the ram, it cannot be accessed from any position on the beam

However, its manufacturing cost is relatively high, it has a very large floor space when there are multiple heads, and the maximum head weight of the manipulator is limited
