Definitions
- the invention relates to an actuating member which is movable by a linear motor and which is mounted so as to be linearly displaceable in relation to a guide housing surrounding this organ.
- a feed unit can be used for installation in machine tools or handling devices.
- a machine tool is known from the publications EP 0 489 857 B1 and DE 690 27 931 T2, in which 6 extendable leg elements are used. These can be designed as telescopically extendable parts, each with a hydraulic cylinder and a piston rod.
- the publication DE 198 42 384 A1 shows a linear guide with a guide housing designed as a profile carrier, approximately U-shaped in cross section, and a carriage which is mounted so as to be displaceable along the guide housing via ball revolutions.
- an electric motor is arranged within the guide housing, which has a primary part attached to the carriage, acting as a rotor, and a secondary part attached to the guide housing, acting as a stand.
- the use of such a linear motor has the advantage that between the motor and the a gear to be moved, which changes the power transmission so that high forces can be achieved is not required.
- the invention has for its object to provide a simply constructed linear motor drive, the design of which maintains small dimensional limits with sufficiently large achievable power transmission.
- the actuating member is designed as an inner tube with a longitudinal slot extending in the longitudinal direction, a rodless piston, which is attached to the guide housing via one or more connecting struts and is penetrated through the slot, being guided in the inner tube.
- a rodless piston which is attached to the guide housing via one or more connecting struts and is penetrated through the slot, being guided in the inner tube.
- the guide housing can be designed as an outer tube.
- the outer surface of the inner tube can have a square shape in cross section. It can be occupied by several rows of permanent magnets arranged one behind the other in the longitudinal direction and acting as secondary parts of the linear motor. Accordingly, a plurality of rows of magnet coils arranged one behind the other in the longitudinal direction and acting as primary parts of the linear motor can be arranged on the inner surface of the outer tube.
- Figure 1 shows a linear motor drive according to the invention in a perspective view
- FIG. 2 shows a longitudinal view of the linear motor drive according to FIG. 1;
- FIG. 3 shows an end view of the linear motor drive according to FIG. 1;
- FIG. 4 shows an inner tube of a linear motor drive according to the invention in a perspective view
- Figure 5 is a longitudinal view of the inner tube of Figure 4.
- Figure 6 is an end view of the inner tube of Figure
- a linear motor drive consists of an inner tube 1 and an outer tube 2, which coaxially surrounds the inner tube 1.
- the inner tube 1 is designed with an inner surface that is circular in cross section and an outer surface that is square in cross section.
- the inside of the inner tube 1 is opened to the outside over the entire length by a slot 3 running in the longitudinal direction.
- a rodless piston 4 is arranged in the interior of the inner tube 1. This serves to guide the inner tube 1 relative to the outer tube 2 and is therefore connected to the outer tube 2 via two connecting struts 5 which extend radially from the interior of the inner tube 1 through the slot 3.
- the outer tube 2, the connecting struts 5 and the piston 4 form a rigid unit.
- the drive of this electric linear motor unit is formed by permanent magnets 6 and magnetic coils 7.
- the inner tube 1 is covered with four rows of permanent magnets 6 arranged one behind the other. Each row is opposite a row of magnetic coils 7, which are arranged on the inside of the outer tube 2.
