Abstract

An assembly device for pressing in a block seal (25) into a component groove (22) provides pivotable jaws (10) which lie laterally against the block seal (25), so that the block seal (25) is prevented from folding over when it is pressed in. The jaws (10) are on a frame (5). To press the block seal (25) into the groove (22), the block seal (25) is first placed on a web (4) on a base (1) and then the jaw (10) is pivoted into a supporting position, in which its inner edge comes into contact reaches the edge of the block seal (25) and thus prevents the block seal (25) from folding outwards when it is pressed into the groove (22) by the web (4).

Description

The invention relates to an assembly device for inserting a sealing ring into the groove of a component.

It primarily relates to the assembly of a so-called block seal in a groove in the base of a control housing of an electrohydraulic brake system, the base of which is placed on a valve block that receives the pumps and valves of the brake system.

So far, the block seal has been pressed manually into the groove. The time required for this is very high because the seal flipped outwards or inwards when the press-in pressure was exerted.

The invention is therefore based on the object of providing an assembly device or aid which makes it possible to significantly reduce the assembly time.

• Einen Sockel, auf dessen Oberseite ein senkrecht von der Oberseite abstehender und ein eine innere und eine äußere Seitenfläche aufweisender Steg verläuft, wobei der Verlauf des Steges dem Verlauf der Nut entspricht,
• einen Träger innerhalb des Stegverlaufs, dessen von dem Sockel abgewandte Oberseite bestimmt ist, das Bauteil derart aufzunehmen, dass die offene Seite der Nut des Bauteils dem Steg zugewandt ist, wobei der Träger senkrecht zur Oberseite des Sockels verschiebbar ist, und
• wenigstens eine vor der Außenseite des Stegs verschwenkbar gelagerte Backe, die derart mit dem Träger gekoppelt ist, dass bei einer Verschiebung des Trägers in Richtung auf den Sockel die Backe verschwenkt wird, so dass eine an dem Innenrand der Backe ausgebildete Stützfläche eine über die Oberkante des Stegs hinausführende Verlängerung der äußeren Seitenfläche des Steges bildet.

To achieve the object, the invention provides that the assembly device has:

• A base, on the top of which a web extending perpendicularly from the top and having an inner and an outer side surface runs, the course of the web corresponding to the course of the groove,
• a carrier within the web course, the upper side of which is remote from the base is intended to receive the component in such a way that the open side of the groove of the component faces the web, the carrier being displaceable perpendicularly to the upper side of the base, and
• at least one jaw pivotably mounted in front of the outside of the web, which is coupled to the carrier in such a way that when the carrier is displaced in the direction of the base, the jaw is pivoted, so that a support surface formed on the inner edge of the jaw extends over the upper edge of the Forms web extending extension of the outer side surface of the web.

The web has the task of pressing the block seal into the groove when the carrier is pressed together with the component placed on it in the direction of the base. The web run must therefore correspond to the run of the groove, which in turn means that each device must be individually matched to a component with a specific groove run.

The carrier is located within the web course so that it can be lowered past the web in the direction of the base, the web resting against the block seal and pressing it into the groove. In order to prevent the block seal from folding outward due to the force acting on it and thus tilting in relation to the groove, the jaw which is pivotably mounted on the outside of the web is provided. This is coupled to the carrier in such a way that when the carrier is moved in the direction of the base, the jaw is pivoted so that the support surface formed on the inner edge of the jaw rests against the block seal and prevents it from tilting as long as it is not yet complete has been pressed into the groove. The inner edge of the jaw thus forms an increase in one of the side flanks of the groove.

In order to keep the jaw pivotable, a frame is provided which surrounds the outside of the web and which is elastically mounted on the base, one or more jaws being pivotably mounted on the frame.

So that each of the jaws can be pivoted into a support position supporting the seal, it is provided that each jaw has an inwardly protruding lever which engages through a slot in the web and which comes to rest against a stop on the carrier. If the carrier - as described above - is pressed down, its stop comes against the levers, whereby the jaws are pivoted in such a way that their inner support surfaces facing the web increase the flank of the groove.

As soon as the jaws are in a supporting position supporting the block seal, the frame is carried by the carrier, which is elastically mounted on the base by means of at least one preloaded spring, so that the block seal, guided by the jaws, is now pressed into the groove of the component can be.

So that after the complete assembly of the block seal in the component the device returns to its basic position, it is provided that the carrier is elastically mounted on the base.

In order to prevent the block seal from also folding inwards, the outer edge of the support lies against the inner side surface of the web. For this purpose, the outer edge of the carrier runs at a minimal distance from the inner side surface of the web.

The outer edge of the carrier and the support surfaces of the pivoted jaws thus form a shaft in the elevation of the groove and thus have the effect that the block seal can be pressed evenly into the groove from the web without it folding inwards or outwards.

In order to ensure unrestricted guidance of the block seal even when the support or frame is tilted, the inner edge of the frame and / or the jaws and / or the outer edge of the support is in each case inclined.

Depending on the course of the seal or groove, two or more jaws are required. Each jaw is held between two bearing brackets on the frame.

So that the component is precisely aligned with the carrier so that the groove runs around the edge of the carrier and above the web, the top of the carrier is provided with bolts or recesses for bolts of the component.

• 2a, b, c, d jeweils Teilschnitte der Vorrichtung zu den einzelnen Schritten der Montage einer Blockdichtung.

The invention is to be explained in more detail below on the basis of an exemplary embodiment. To show:

• 1 an exploded view of the device, and the
• 2a, b . c . d partial sections of the device for the individual steps of assembling a block seal.

As the 1 shows, a device according to the invention consists of a base 1 that is about props 2 on one platform 3 is arranged. On the top of the base facing away from the platform 1 there is a footbridge 4 , It is also located on the outside of the footbridge 4 a square frame 5 with its corners on prestressed springs 6 on the base 1 is stored. The frame 5 has four consoles 7 that protrude like a tower on the corners of the frame.

Between two consoles 7 an elongated cheek extends 10 made with axle pins 11 . 12 at the ends of the axles in the brackets 7 is pivotally mounted about its longitudinal axis.

The 1 shows the cheeks 10 in their support positions, which means that their inner edge is substantially perpendicular to the base 1 stands. The cheeks 10 thus form a frame-shaped frame within which there is a support 15 is located, the outer edge 16 of the carrier 15 the inside edge of the of the cheeks 10 Formed socket is at a constant distance opposite, so that around the carrier 15 circumferential shaft is formed. The carrier 15 rests on feathers 20 that are within the web 4 on the base 1 support. These springs have no preload.

On top of the carrier 15 becomes a component 21 set with its base having a groove down, the groove along and outside the outer edge 16 of the carrier 15 runs. That from the outer edge of the carrier and from the inner edge that of the cheeks 10 formed socket formed an increase in the groove. The component is e.g. B. a housing that accommodates an electronic control for a brake system and coils for electromagnetic actuation of valves and that later using a block seal 25 sealed to a so-called valve block.

For mounting the block seal 25 Now proceed in the groove like this 2a-c clarify each a section through one of the cheeks 10 and that in its middle, between the consoles, where on the inner edge of the cheek 10 one in a recess 13 on the carrier 15 protruding lever 17 located. The recesses 13 are cylindrical and have a diameter that is smaller than that of the pin-shaped lever 17 , so that the lever can be moved up and down in the recess.

On the top of the base 1 runs the jetty 4 and all around a paragraph above which the frame 5 located from the outside of the web 4 is guided and centered.

To do this are the inner edge of the frame 5 and the inner edges of the cheeks 10 each inclined by approx. 3 °, the lower edge of the inner edge being set back in relation to its upper edge. This is also when the frame is tilted 5 still a non-restrictive tour through the footbridge 4 guaranteed.

In the interior inside the footbridge 4 and above the base 1 the carrier dives 15 one and is there on non-preloaded springs 20 stored. On this carrier 15 is a component 21 put on that in its the carrier 15 facing underside a circumferential groove 22 has, the component 21 so to the carrier 15 is aligned that the groove 22 runs all the way to the outer edge of the carrier, the web 4 the course of the groove 22 follows.

The outer edge 16 of the carrier 15 is from the inside of the footbridge 4 guided. This is the outer edge 16 3 ° inclined, the lower edge of the outer edge 16 is set back from its upper edge. This is also when the carrier is tilted 15 continues to ensure a non-restrictive guidance through the web.

First, the block seal 25 around the carrier 15 placed so that it wraps around the upper section of its outer edge 16 is applied. Then the component 21 with the groove 22 down on the carrier 15 put on and according to 2 B against the force of the feathers 20 pressed down. The block seal 25 comes into contact with the levers 17 , so that when the component is pressed down further 21 or the carrier 15 the levers 17 pressed down and thereby the jaws 10 be pivoted until - like that 2 B shows- their inner edges essentially parallel to the web 5 is aligned. The levers 17 move through slots 18 in the jetty 4 , The dimensions are chosen so that - as soon as the block seal 25 at the top edge of the web 4 fits - the cheeks 10 at one stage 19 of the frame 5 strike so that it cannot be pivoted any further, see 2 B , Because that through a bolt 23 preloaded springs 6 of the frame 5 apply a higher counterforce than the springs 20 for the wearer 15 , only the carrier becomes in this phase 15 lowered while the frame is at its original distance from the base 1 remains.

At the same time, the upper surface of the recesses 13 the levers 17 reached so that - according to 2c - if the carrier is pressed down further 15 the frame 5 and the cheeks 10 with compression of the pre-tensioned springs 6 get picked up.

The jetty 4 presses the block seal 25 by the from the outside edge of the wearer 15 and from inside edges of the jaws 10 formed shaft in the groove 22 , which prevents breaking out inwards or outwards because the outer edges of the jaws are there 10 or the outer edge of the carrier 15 are located. The shaft is open in a trapezoidal cross-section downwards because of the inner edges of the jaws 10 and the inside edge of the wearer 15 are slightly inclined. This tolerates tilting of the carrier and the jaws and still ensures a sufficiently straight guide for the block seal 25 reached.

Once the block seal 25 the bottom of the groove 22 reached, the press-in process is complete. The component 21 can accordingly 2d from the carrier 15 be removed so the feathers 6 . 20 the carrier 15 and the frame 5 return to their basic positions. The jaws are swung back because of the levers 17 from the lower surface of the recesses 13 get picked up.
