Description

A hand tool for setting plugs is given. The hand tool can be designed in particular for setting sealing plugs in openings in body components. Furthermore, a method for setting plugs is specified.

In the manufacture of the body of a vehicle, holes are often set or punched in order to ensure, for example after painting the outlet of the paint or to allow the generation of complex geometries.

After production, these holes usually have no other function and can even lead to damage in the form of corrosion attack of the body by the entry of liquids. The acoustics of the vehicle interior can also be influenced by the component openings. Remedy for this is the plugging of the holes by means of injection molded parts following the functional fulfillment.

Currently, this is usually done manually by the workers in the assembly process. Attempts to automate the process are proving to be a major challenge, as industrial robots, due to their size, have difficulty getting into the niches and cavities of the body. The robots require more time during assembly than the workers.

Another possibility is in the publication DE 10 2014 211 257 A1 explained. It is a joint orthosis intended to protect the body parts, especially the thumb. Namely, the plugging operation is performed up to 2,000 times per shift by a worker. An overload of the thumb joint is thus easy to understand. Ultimately, the thumb support as an ergonomic tool but a troublesome job for the worker, as it is mounted on a glove and therefore every time again and has to be pulled out. Furthermore, each stopper must be carried individually and the dexterity and gripping feeling are slightly limited by the material at the tip of the thumb and complicate possible other assembly operations within the activity to be performed.

The publication DE 10 2015 211 543 A1 describes a hand tool for setting sealing plugs in openings in a body component with a setting device in which a stopper magazine is accommodated with a plurality of plugs, which can be placed without reloading directly after each other into the respective openings by means of the setting device and a method for securely setting the plugs, wherein the plugs are pushed out of the plug magazine accommodated in the setting device via a drive unit in predefined steps. On the hand tool a manual trigger is arranged, via which the drive unit can be controlled, so that the plugs are movable into predefined Ausschubpositionen.

A disadvantage of the in the document DE 10 2015 211 543 A1 Hand tool described is that only sealing plug of a certain size can be set by means of the hand tool.

It is therefore an object to be solved, at least some embodiments, to specify a hand tool for setting plugs, by means of which plugs of different sizes or with different diameters can be set without reloading. Another object is to provide a method for setting plugs.

These objects are achieved by an article and a method according to the independent patent claims. Advantageous embodiments and further developments of the subject matter will be apparent from the dependent claims, the following description and from the drawings.

A hand tool described here for setting plugs in openings in a body component has a setting device for receiving a stopper magazine, a stopper magazine for receiving a plurality of plugs, a drive unit for pushing out plugs from the setting device and a manual trigger, via which the drive unit can be actuated. on.

The plug magazine may for example have a cylindrical shape and for receiving a plurality of sealing plugs, which may in particular be made of plastic, be formed.

According to the invention, the plug magazine has at least one first sub-magazine and at least one second sub-magazine, which are designed to receive plugs of different sizes. For example, the first sub-magazine for receiving first plug, each having a first outer diameter formed, and the second Teilmagazine for receiving second plug, each having a second outer diameter, formed, wherein the first outer diameter is greater than the second outer diameter. For example, each partial magazine may have a partial area which comprises the one or more plugs arranged in the respective partial magazine in a form-fitting manner.

Furthermore, the second sub-magazine forms a drive element for pushing out one or more plugs arranged in the first sub-magazine. For example, the first sub-magazine may be formed by a section of the stopper magazine, in particular a portion of the stopper magazine formed in the region of the outlet opening, and the second sub-magazine may be designed to be movable relative to the first sub-magazine, wherein a stopper arranged in the first sub-magazine is directly or indirectly through the second Part magazine can be moved so that the plug is pushed out of the plug magazine.

According to a further embodiment, the second partial magazine is at least partially telescopically designed to be displaceable in the first partial magazine. Preferably, the second sub-magazine can be moved directly or indirectly by the drive unit, which is actuated by the manual trigger, relative to the first sub-magazine to move a plug from the plug magazine or from the outlet opening setting means.

The manual trigger is preferably in an advantageous embodiment as a one-handed handle, e.g. as a one-hand grip with pistol grip shape, formed. By using a one-handed handle, the second hand remains for guiding and attaching the hand tool to the body component.

According to a further embodiment, the hand tool for setting plugs has one or more further partial magazines, wherein each of the partial magazines is designed to receive plugs of different sizes. Each additional sub-magazine preferably forms in each case a drive element for pushing out stoppers of another sub-magazine.

For example, the hand tool can have a third sub-magazine in which third plugs having a third outer diameter, which is smaller than the second outer diameter, are arranged. The third sub-magazine can thereby form a drive element for pushing out plugs, which are arranged in the second sub-magazine. Accordingly, the hand tool may comprise a fourth sub-magazine for receiving fourth plugs having a smaller outer diameter than the third plugs, wherein plugs arranged in the third sub-magazine can be moved through the fourth sub-magazine, etc.

In particular, the individual sub-magazines may comprise sections which are each designed to directly move or displace plugs of a preceding sub-magazine. Furthermore, the individual sub-magazines may each have subregions or subareas that are configured to cooperate directly with subregions or subareas of a preceding subagazine, so that the individual subagazines can be telescoped into each other to successively the individual, different in size plugs from the stopper magazine or to be transported out of the setting device. The last sub-magazine can be moved directly or indirectly by the drive unit. For example, the drive unit may have a punch, which act directly on the last sub-magazine and this can move. Alternatively, a carriage may be arranged between the punch and the last partial magazine, so that the punch can move the last partial magazine indirectly via the displaceable slide.

According to a further embodiment, a magnetic positioning aid is provided at the outlet opening of the setting device. For example, the magnetic positioning aid can be arranged circumferentially around the outlet opening of the setting device. The magnetic positioning aid may e.g. have a permanent magnet. Due to the magnetic positioning aid a simpler centering of the plug to be set can be achieved.

According to a further embodiment, the plug magazine and / or the partial magazines are at least partially transparent. As a result, it can advantageously also be detected without opening the hand tool or the stopper magazine from the outside, how many plugs are still arranged inside the stopper magazine.

According to a further embodiment, the second sub-magazine is designed to be displaceably guided within the first sub-magazine, and each further sub-magazine is designed to be displaceably guided within the preceding sub-magazine. As a result, an inner guidance of partial magazine part magazine can be achieved.

According to a further embodiment, the second sub-magazine and each further sub-magazine are formed directly adjacent to an inner wall of the stopper magazine displaceably guided. As a result, the plug magazine can form an outer guide of the second sub-magazine of the further sub-magazines.

The hand tool for setting plugs described here can advantageously be used to set plugs of different sizes or with different outer diameters.

Furthermore, a method for setting plugs in openings in a body component is given. The hand tool used may be one or more Have features of the aforementioned embodiments. The embodiments described above and below apply equally to the hand tool as well as to the method for setting plugs by means of the hand tool.

In the method, a hand tool described herein and a body member having a plurality of openings are provided. Subsequently, at least one arranged in the first sub-magazine first plug is set with a first outer diameter in a first opening of the body part by means of the hand tool, in which the manual trigger of the hand tool is operated.

Thereafter, a second partial magazine arranged second plug with a second outer diameter, which is greater than the first outer diameter, set in a second opening of the body part by means of the hand tool. The placement of the plugs is post-unloaded.

When setting the first plug, the second partial magazine is preferably used as the drive element for pushing out the first plug. In particular, a subregion of the second sub-magazine can directly or indirectly displace the first stopper by displacing the second sub-magazine relative to the first sub-magazine by actuating the manual trigger and the drive unit moved thereby.

Similarly, one or more further plugs of different size or with different outer diameters, which are each arranged in different further sub-magazines, are moved by a telescopic displacement of the individual sub-magazines from the outlet, in particular by a respective preceding sub-magazine the respective plug directly or indirectly drives.
