Abstract

Changing device for units on measuring devices and machine tools with the aim to increase the safety when assembling the units and to facilitate the joining together. The task is mainly to produce by mechanical means the necessary coupling forces to close the changing device in this self. The device consists of a housing in which a helically movable guide part is mounted with a socket. On a unit to be plugged, which is inserted into the housing, a plug and Fuehrungselemente are provided. In screw-shaped grooves of the guide part, guide pins arranged in the housing intervene. After introduction of the unit to be inserted into the housing, the guide elements engage in guides in the guide part. By turning the unit about the axis is achieved by means of grooves and Fuehrungsstifte that the socket approaches the plug and thus closes the contacts.

Title: Interchangeable device for assemblies on measuring instruments and machine tools

Field of application of the invention

The invention relates to a changing device for Bauj units of Keßgeräten and machine tools, such as photoelectric measuring devices, load and measuring heads and other measuring devices, from which a Yielzahl of information for further processing are forwarded.

Characteristic of the known technical solutions

Ss are interchangeable devices for signalers known, which usually consists of a mechanical mount, flange bayonet connection u. Ä. And at least one electrical connector for the connection of signal lines exist. The coupling of the corresponding unit is carried out so that first the connectors are closed and then the mechanical 'attachment takes place. For signalers with many contacts and signal lines inevitably increases the necessary Eiigekraft for the connector, and there is a risk when connecting these connectors to sensitive parts of measuring instruments, that they are damaged.

Also in electrical engineering multiple plug devices are known (DS-AS 2136 022, DS - AS 2454 369), which consist of plug parts that are fixed to each other.

In this case, means are provided which allow an unambiguous assignment of the contact elements. Through a basson

Connection, the two connector parts, after the Eontaktelemente are connected to each other. In DE - IS 16 656 44, an electrical connector with a first and. Second connector is described, the ge have a housing with contact elements · The connector further comprises a locking ring on which locking lugs are arranged, each in a locking groove on the second connector are insertable. These grooves run first in the direction parallel to the axis and then in the tangential direction · In this connection, the contacts must be connected by applying a joining force · The locking lugs and the grooves serve only to realize a solid plug connection.

Object of the invention

It is an object of the invention to eliminate the disadvantages of the known exchanging devices, to increase the security of the devices and to facilitate the assembly of the structural units.

Principle of the invention The invention has for its object to provide a changing device for assemblies of measuring instruments and machine tools, with which the required coupling forces for closing said changing means in this generated itself by mechanical means, and thus the coupling operation is substantially facilitated.

According to the invention this object is achieved in a changing device, consisting of a device arranged in a housing receiving unit, which comprises a guide member and a socket, achieved in that the socket on a guide member which is provided with one or more helical grooves and which guides

and comprises a locking groove, is arranged in the housing, that in the housing in the helical hats engaging guide pins for helical movement of the guide member and locking element for fixing the position of the guide member are arranged, and that on the unit to stekkenden a plug with Eontakten and in the guides of the guide member By applying the invention is, in particular at high

10. Joining forces, achieved an easy to produce, unique and secure connection of units. The risk of causing damage to sensitive equipment parts is largely eliminated.

embodiment

The invention will be explained below-an embodiment. In the accompanying drawing show:

Fig. 1 is a section through the Y / echselvorrichtung

and

Fig. 2 is a view of the changing device from below.

In the changing device according to Fig. 1 is in a housing 1, which is inbeipielsweise arranged on a measuring device, not shown, a in conjunction with the guide pin 7 a screw joint forming guide part 2, on which a provided with contacts 3 socket 4 by means Fastening elements 5 »for tolerance compensation slightly laterally displaceable, is attached. In the T / and the guide member 2, one or more helical grooves 6 are incorporated, in which in the housing 1 mounted guide pins • 7 engage the helical movement of the guide member 2. To fix the position, with respect to a starting position of the guide member 2, relative to the housing 1, is

232913 8

provided on the circumference of the guide part 2 at least one locking groove 8, in which locking element 9, which is mounted in the housing 1, engages.

Sine unit to be stuck 10, for example, a transmitter or probe, which is inserted after the Pig, 1 from below into the housing 1, has at its, the socket 4 end facing guide elements 11 and provided with contacts 12 plug 13 · An dem, the plug 13 remote from the end of the unit to be plugged 10 are shown in Pig. 1 and 2 segments 14 are provided, which can be inserted into (recesses 15 of the part 16 fastened to the housing 1. With these, a bayonet connection can be produced by turning the unit 10 to be staked around the longitudinal axis.

To a clear and sidhere connection between Stekker 13 and socket 4, z. B. when changing the unit to be staked 10, this unit 10 is inserted from below (Fig. 1) as far into the housing 1, that the guide elements 11 engage in guides 17 of the guide member 2. By rotation of the unit 10 and thus on the guide members 11 and the guide member 2 with the socket 4 about the longitudinal axis is achieved that due to the engagement of Führungsstif- '' - ^; te 7 iD the Fut 6 socket 4 on plug 13 and thus the contacts 3 and 12 are closed.

A safeguard against falling out of the unit 10 from the housing 1 is achieved by a realized by the segments 14 and the part 16 bayonet connection. Securing means 18 against unintentional release of the connection are provided in part 16.

When removing the unit to be inserted 10, the movement takes place in the reverse order as when inserting.
