Field of application of the invention

Device for inserting elastic rings in inner ring grooves

These are preferably elastic rings, which are introduced into bushings for piston rods, spindle, cables and plugs.

Characteristic of the known technical solutions

A known technical solution is that manually the elastic ring is inserted through a funnel-shaped sleeve. As the prior art, a device, as shown in DE Auslegeschrift 1 478 798, known, with which an elastic ring is inserted into an annular groove, wherein the ring is pressed from the outside with two pressure pins achtförmig in a groove of a piston and then is introduced with another movement by means of the piston in the annular groove.

In SU-certificate 1 110 596 a device is described in which two levers grasp an elastic ring at two points and press it through a conical part into a central part with an inner ring groove.

The solutions shown have the disadvantages that during manual assembly, the introduction of the elastic. Ring is poor quality possible, the ring can be damaged. When using the device from the. DE Auslegeschrift 1 478 798 two different gripping elements must be operated simultaneously.

Object of the invention

The aim of the invention is to bring in high numbers of elastic rings with consistent quality and minimum expenditure of time in internal grooves.

Explanation of the essence of the invention

The invention has for its object to introduce undamaged the elastic rings in the groove, that even with a larger number of rings aile rings are aligned evenly and centrally in the groove, and that the device with a single stroke, down / up, introduces the ring and aligns.

According to the invention the object is achieved by the device described below.

The device consists of the piston rod, which is firmly connected to the upper piston, the piston connection, the piston phase and the lower piston. The guide sleeve with a conical bore, which merges into a cylindrical bore, is provided at the lower end with a centering. The pressure cone is slidably mounted on the piston rod and is supported on the underside in the conical bore of the guide sleeve, on the top of the pressure cone is supported by a compression spring which is pushed over the piston rod.

Ausführungsbeispiei

The invention will be explained in more detail below using an exemplary embodiment.

In the accompanying drawings show: '

Fig. 1: The device with inserted elastic ring

Fig. 2: The device when inserting the elastic ring in the cylindrical bore

Fig. 3: The device when inserting the elastic ring into the annular groove

Fig. 4: The device during alignment and centering of the elastic ring

According to FIG. 1, the device is placed on the component 14 and aligned with the centering of the guide sleeve 10.

The elastic ring 11 is inserted into the conical bore 12 of the guide sleeve 3 when the pressure cone 2 is raised. After the pressure cone 2 rests against the guide sleeve 3 again, the entire piston, consisting of the upper piston 4, moves lower

Piston 5, piston phase 6 and piston connection 7, down. '

Referring to Fig. 2, in the downward movement of the entire piston, the elastic ring 11 in the region of the transition of the conical bore 12 into the cylindrical bore 13 through the upper piston 4, in that it can penetrate into the tapered part of the piston connection 7, as a corrugated spring washer deformed.

As shown in FIG. 3, the entire piston slides further down, while the upper piston 4 so far with the elastic ring 11 until it snaps into the annular groove 9 and again predominantly assumes the circular shape.

According to Fig. 4, the entire piston slides back up. When passing the piston phase 6 and the lower piston 5 on the elastic ring 11 this is aligned and centered.

Claims (1)

Invention claim: 1. A device for introducing elastic rings, in which a piston with a piston rod, piston connection and a lower piston inserted in a conical and cylindrical bore of the guide sleeve, wherein a pressure cone is slidably disposed on the piston rod and on its underside in the conical bore of the Führungshüise supported, characterized in that between the piston rod (1) and piston connection (7) an upper piston (4) is arranged and , between the lower piston (5) and the piston connection (7), a piston phase (6) forms the transition; on the top of the pressure cone (2) is a compression spring (8) which is pushed over the piston rod (1). _u
