Definitions

  • the invention relates to a motor-driven crimping tool comprising a support column on which two crimping tools are mounted, one of which is fixed and the other in a guide of the support column is displaceable, a signal-actuated motor with a motor housing which is rigidly secured to the support column and an actuator encloses that is connected to the displaceable crimping tool and a controller for operating the motor.
  • Such a crimping tool is known. It is used in the connection of electrically conductive cables of a diameter of several millimeters and is operated by a pressurized with compressed air piston / cylinder unit. This has a comparatively large effective diameter in order to generate the forces required for a crimping process using the working pressures of 6 or 12 bar available in conventional compressed air networks. Accordingly, the crimping tool is cumbersome to use and, in particular, less suitable for use in difficult to access places. Presentation of the invention
  • the invention has for its object to further develop a crimping tool of the type mentioned that results in a reduced size. This object is achieved with a crimping tool of the type mentioned above with the characterizing features of claim 1.
  • the dependent claims relate.
  • the motor is an electric motor with a rotor rotating about an axis, which is provided on the support column, at least one crimping tool and / or the actuator a deformation sensor, the / the resulting during the crimping, mechanical deformation the support column, the crimping tool and / or the actuator is suitable and transforms the deformation into a signal that corresponds to the size of the deformation proportional and that the deformation sensor is signal conductively connected to the control of the motor and a return of the displaceable crimping tool to its original position causes the occurrence of a signal that reaches or exceeds an arbitrarily settable value.
  • the invention is based on the recognition that electric motors with a rotor rotating about an axis are distinguished by an excellent robustness and accordingly have a long service life.
  • the conversion of the fast rotational movement in a slow forward movement of the displaceable crimping tool of a crimping tool always requires the use of a transmission with an extremely high transmission ratio and a correspondingly large switch-off inertia.
  • the size of the crimping tool according to the invention is significantly reduced compared to the known design. As a result, it can easily be used in tight places, for example at assembly sites located inside motor vehicles.
  • Threaded nut co-operating threaded rod is arranged, which together the rotational movement of the rotor in a transverse motion the mother and the associated, movable crimping tool convict.
  • a transmission housing is provided between the electric motor and the displaceable crimping tool, in which the threaded rod axially immovable and rotatable and the threaded nut is axially displaceable and non-rotatably received.
  • the threaded rod is expediently supported on at least one ball bearing. As a result, it is particularly easy to rotate and accordingly requires only low drive forces. The engine can be reduced accordingly in terms of its size.
  • the gear housing and the motor housing are expediently arranged next to each other, wherein the threaded rod and the rotor of the electric motor are connected by a belt drive.
  • the deformation sensor on the support column it has proven to be advantageous if it is positioned between the fixed crimping tool and the attachment point of the motor housing.
  • the attachment to the support column can be carried out in an elongated design by means of spaced in the direction of the force introduction direction machine screws. Any elastic deformations of the support column are transmitted directly to the sensor and converted into a signal that is proportional to the size of the deformation. It can therefore be evaluated and used to control the motor to obtain error-free crimping and avoid damage caused by overload. Since the signal is the engine in the controls design according to the invention bypassing the gear reduction directly, the achievement of both objectives is guaranteed in an excellent degree.
  • the deformation sensor is formed by an electrical tension and / or pressure sensor.
  • the resulting during the intended use deformations can be characterized excellent and capture directly.
  • FIG. 1 shows an exemplary embodiment of the crimping tool according to the invention in longitudinal section
  • FIG. 2 shows the crimping tool according to FIG. 1 in a cross-sectional representation along the plane A-A
  • a motor-driven crimping tool is shown in longitudinal or cross-sectional view, comprising a support column 1, on which two crimping tools 2, 3 are mounted, one of which 2 fixed and the other 3 in a guide 4 of Supporting column 1 is displaceable, a signal-actuated motor 5 with a motor housing 6 which is rigidly attached to the support column 1 and an actuator 7 surrounds that is connected to the displaceable crimping tool 3 and a controller for actuating the motor 5.
  • the motor 5 consists of an electric motor with a rotor rotating about an axis. This is connected by a belt drive 12 with an actuator 7 that is formed by a threaded spindle is supported by ball bearings 11 on the gear housing 9.
  • the gear housing 9 comprises in the lower part of a guide of hexagonal profile, as seen in Figure 2.
  • the actuator 7.1 is mounted, which is designed in the manner of a threaded nut and at the bottom of the drawing, the displaceable crimping tool 3 carries.
  • the displaceable crimping tool 3 opposite lying at the lower end of the support column 1 is a festgelagertes, further crimping tool 2 is provided.
  • Deformation sensors 8 may be exclusively, alternatively or cumulatively provided on the support column 1, at least one crimping tool 2, 3 and / or the actuator 7, 7.1. In most cases, the use of a single sensor is sufficient. This can be attached particularly advantageous to the support column 1 and replace easily in case of damage.
  • the control needed to operate the illustrated crimping tool is not shown in the drawing. It is generally integrated into the motor housing 6 and is protected at this point to a particularly good extent from mechanical damage.
  • a key switch is generally provided. This causes via the not shown in the drawings control a rotation of the rotor contained in the electric motor.
  • the rotation is transmitted through the belt drive 12 to the trained as a threaded spindle actuator 7, which is in engagement with the internal thread of the designed like a threaded nut actuator 7.1.
  • This is by a hexagonal guide of the gear housing. 9 prevented from following the rotational movement of the actuator 7, while the latter is supported on ball bearings 11 in the axial direction on both sides in the gear housing 9 and thereby prevented from an axially directed evasive movement.
  • the rotational movement of the actuator 7 causes as a result thereof a downward Relatiwerlagerung of the actuator 7.1, which is transmitted directly fixed on its face, displaceable crimping tool 3.
  • the displaceable crimping tool 3 is thereby displaced in the direction of the stationary crimping tool 2. This results in the possibility that the relatively displaceable and the rigidly fixed crimping tool meet directly, with the result that an elastic deformation of the support column 1 results. This is detected by at least one of the sensors 8 and converted into a signal that corresponds to the size of the deformation proportionally.
  • the control which is not reproduced in the drawing, causes a reversal of the motor in the opposite direction of rotation and thus an immediate return of the movable crimping tool to its starting position. A plastic deformation or even damage to the crimping tool is thereby reliably avoided.
  • the actuation of the pressure switch triggers a downward relative bearing of the displaceable crimping tool, which, however, causes the implementation of a crimping process.
  • the wire ends to be connected are jointly enclosed by a crimp, which normally consists of metallic material and is plastically deformed such that the two wire ends are subsequently connected inseparably by the crimp.
  • the necessary forces are considerable. They will be like that increased long, until a sufficient, plastic deformation of the crimp has occurred.
  • the value in this regard differs depending on the size of the crimp and can be determined very easily in the experiment. If it is reached, then at least one of the sensors 8 triggers a reversal of the motor 5 and a return of the displaceable crimping tool to its original position. Thus, the required, firm connection of the two wire or cable ends is achieved at each nachnachneden crimping, without causing damage to the crimping tool. Also, use in the connection of other, columnar body is possible.
  • the crimping tool according to the invention is characterized by an extremely high robustness and good manageability.
  • the electrical energy required for operation can easily be supplied using thin, flexible cables.
  • a use of difficult-to-reach places of use is nothing contrary.

Un de ces outils de sertissage (2) est fixe et l'autre (3) peut coulisser dans une coulisse (4) de la colonne de support (1). Ladite pince à sertir comprend également un moteur (5) commandé par signaux, qui présente un carter de moteur (6) fixé rigidement à la colonne de support (1) et entourant un élément de réglage (7) qui est relié à l'outil de sertissage coulissant (3), ainsi qu'une commande conçue pour actionner le moteur (5). Le moteur (5) est un moteur électrique avec un rotor qui tourne autour d'un axe. Un capteur de déformation (8) se trouvant sur la colonne de support (1), sur au moins un outil de sertissage (2, 3) et/ou sur l'élément de réglage (7, 7.1) est conçu pour détecter la déformation mécanique apparaissant lors du processus de sertissage et la transformer en un signal qui est proportionnel à l'amplitude de la déformation. Le capteur de déformation (8) est relié à la commande du moteur (5) de manière à pouvoir transmettre des signaux. Lorsqu'un signal qui atteint ou dépasse une valeur pouvant être réglée arbitrairement apparaît, l'outil de sertissage coulissant (3) est ramené à sa position de départ.
