Tool for mounting a tailpipe trim to a tailpipe

Technical area

The invention relates to a tool for mounting a tailpipe trim to a tailpipe. Furthermore, the invention relates to a mounting arrangement for mounting a tailpipe trim to a tailpipe. The invention further relates to a method for mounting a tailpipe trim to a tailpipe. State of the art

It is known from the prior art, to attach tailpipes by hand or with mechanical aids to tailpipes, for example by a tailpipe cover is pushed onto a tail pipe and fixed with clamps on the tailpipe. Such methods of mounting the

Tailpipe are associated with relatively high expenditure of time. The manual assembly can cause errors in the positioning of the tailpipe trim, for example due to friction or friction

Recoil forces when sliding the tailpipe trim. Furthermore, the tailpipe baffle can only be incompletely fixed along its circumference if, for example, the bail is not fixed properly. In addition, show none known in the prior art tools

Confirmation possibility of proper installation. No data on relevant installation parameters, such as the forces occurring during installation, the installation time or the number of installed tailpipe trims, are recorded.

It is therefore an object of the invention to provide a tool by which the mounting of the tailpipe aperture can be done quickly and accurately without setback. It is a further object of the invention to provide a

Mounting arrangement for mounting a tailpipe trim to provide a tailpipe available. Finally, it is an object of the invention, a

Specify a method for mounting a tailpipe trim.

The object is achieved by a tool according to claim 1. The features of the mounting arrangement are mentioned in claim 13. The features of the method according to the invention are specified in claim 14. Advantageous embodiments will be apparent from the respective dependent claims. Disclosure of the invention

The tool according to the invention for mounting a tailpipe trim to a tailpipe of a vehicle has a clamping device. This can be fixed to the tailpipe. The tool also has a

Moving mechanism. Through this is the tailpipe trim,

in particular axially, can be pushed onto the tailpipe.

By securing the clamping device to the tailpipe, the tool is also fixed in position relative to the tailpipe, intercepting assembly forces. The tool can then no longer be moved, in particular by recoil forces when the

End tube is pushed onto the tailpipe. This will do that Sliding the tailpipe trim on the tailpipe simplified and

accelerated. The positioning of the tailpipe trim can be done more accurately than with a manual mounting of the tailpipe trim to the tailpipe. For this exact positioning of the movement mechanism can be used, which the tailpipe to a fixed

Delays the track on the tailpipe.

In an advantageous embodiment of the tool has the

Movement mechanism on a drive. This drive can

in particular having a motor, which in the tool

can be arranged so that the drive for positioning the

Tailpipe trim is machined. Alternatively or additionally, the drive may have a spindle and / or a toothed belt to control the desired final position of the tailpipe.

The tool can be powered by a first drive for the

Movement mechanism and a second drive for the

Clamp mechanism feature. Advantageously, the movement mechanism may have a common drive for actuating the clamping device and the movement mechanism. Then, the clamping device can be activated when the tailpipe is pushed by the movement mechanism on the tail pipe. As a result, the tool is fixed to the tailpipe, when the tailpipe is pushed. This can ensure that the effect of recoil and assembly forces during assembly of the tailpipe trim is suppressed.

In a further embodiment of the tool, the clamping device has a spreading mechanism for fixing the tailpipe. Such a spreading mechanism made possible by the gradual spreading a simple way a simultaneous fixing of the tool to the tail pipe, when the tail tube is pushed by the movement mechanism on the tail pipe. The spreading mechanism may comprise a cone or a link kinematics, which is arranged in particular in the middle of the clamping device. Furthermore, the spreading mechanism may comprise at least one clamping spring or clamping strip, which is deflectable by the cone when the cone is moved relative to the clamping spring

In this case, a first portion of the deflected clamping spring on the cone and a second portion on the tail pipe can be arranged, such that the clamping spring between the cone and tailpipe can be clamped. Then the clamping spring can be fixed (clamped) by the cone on the inner wall of the tailpipe.

Advantageously, the tool has several clamping springs or

Terminal strips, which are arranged around the cone around, such that they can be spread open by the cone and clamped between the cone and tailpipe. When the cone deflects the clamping springs, the clamping springs or terminal strips are increasingly stronger against the

Inner wall of the tail pipe pressed. As a result, the tool is gradually attached more strongly to the tailpipe. Then, a spreading mechanism for clamping the tool to the tail pipe is formed in a comparatively simple manner. Several, in particular all, clamping springs can be designed the same.

In a further embodiment of the tool, the

Clamping a, in particular cup-shaped, holder, in which the tailpipe is insertable. This allows the

Endrohrblende against displacement in the radial direction or unwanted tilting relative to the tool during the

Sliding on the tailpipe to be secured.

The tool may comprise a carriage on which the cone is arranged, so that at least a part of the clamping device is movable with the carriage. The carriage may be arranged on an arm of the tool. In this way, an actuator is formed on the tool, which in conjunction with the drive in the

Sliding the tailpipe rectilinear movement of the with the

Sled connected cone allows.

In an advantageous embodiment of the tool, the cup-shaped holder is arranged on the carriage, so that the cup-shaped holder is movable with the carriage. Then in particular by the

the aforementioned actuator in the form of the carriage and an arm of the

Tool on which the carriage is arranged, a rectilinear movement of the holder and thus the tailpipe are made possible, which is arranged on the holder. In a further embodiment of the tool, the drive is magnetic, pneumatic, hydraulic or in particular

formed electric drive, in particular a rectilinear

Movement of at least parts of the movement mechanism over a distance of 0 mm to 200 mm allows, so that the tailpipe can be pushed by a maximum of 200 mm. Through these drive forms, a machine drive can be implemented in a comparatively simple manner. An electric drive can be trained particularly energy-saving.

Advantageously, the tool has a force gauge, in particular with a sensor. By such a force gauge, in particular the fixing force of the clamping device and / or the force can be measured be necessary to the tailpipe trim on the tailpipe

postpone. In addition to the fixing force and other forces occurring during the postponement, further process parameters such as the duration of the push-on cycle, the end position of the tailpipe baffle, processed quantities and the duration of the assembly steps can be detected and stored by sensors of the tool. These data can be transmitted to central controllers.

The tool may have a displacement measurement. With such a distance measurement, the distance of the pushing on of the tailpipe baffle on the tailpipe can be measured and in particular on a central one

Control be reported.

A viewing window can form part of the tool. With such a window can be checked whether the tailpipe in the

Clamping device sufficiently deep in the tool, in particular arranged in the cup-shaped holder, in particular inserted, is.

The tool may have a directional indication that aligns the tool and the tailpipe bezel. In particular, it can be measured by a direction indicator whether the tool or the tailpipe orifice is oriented at an angle, ie not parallel, to the tailpipe or is rotated at an undesired angle in the circumferential direction of the tailpipe relative to the tailpipe. The direction indicator can in particular have a spirit level.

The tailpipe orifice may have a drainage hole. The tailpipe baffle must then be installed in such a way that the drainage bung of the tailpipe baffle is in the final position of the tailpipe baffle in the mounted state in vertical downward direction, towards the ground. A when mounting the tailpipe in the vertical direction at the bottom of the

Clamping device, in particular down in the cup-shaped holder, arranged vertically upwardly aligned snapper of the clamping device e.g. in the form of a spring-loaded projection can be introduced into the drainage hole of the tailpipe.

This allows the correct orientation of the tailpipe in

Circumferential direction of the tailpipe trim relative to the tool

be ensured. The tool can in turn be aligned with the aid of the aforementioned direction indicator with the correct orientation relative to the tailpipe.

In an advantageous embodiment, the tool has at least one tab which is designed to hold the tool or cable guide. In particular, a loop can be passed through the tab, which is fastened to a ceiling of a workshop bar or which can put an operator of the tool, for example, around the neck or shoulder. The cable guide can be made safer by such a tab.

A mounting assembly for mounting a tailpipe trim on a

Tailpipe has a tailpipe, a tailpipe and a

inventive tool for mounting the tailpipe trim.

By such a mounting arrangement is a suppression of the effect of recoil forces and friction forces and others in the

Pushing the tailpipe aperture on a tailpipe occurring forces and thus an accurate positioning of the tailpipe aperture possible.

In a method of mounting a tailpipe trim on a

Tailpipe with a mounting arrangement, in particular one before

described mounting arrangement, a clamping device on the Tailpipe fixed. Then a movement mechanism pushes the

Tailpipe trim on the tailpipe. In this case, by suppressing the action of the recoil and assembly forces, the tailpipe baffle can be slipped onto the tailpipe in a simple and accurate manner by a desired distance.

An advantageous embodiment of the method has the following

Steps on:

a. Placing the tailpipe trim on the tool;

b. Manually, at least partially pushing the tailpipe trim onto the tailpipe, in particular until the tailpipe fascia claws in the tailpipe trim touch the tailpipe;

c. Fixing the tool to the tailpipe;

d. Mechanical sliding of the not yet deferred part of the tailpipe baffle by the movement mechanism of the tool on the tailpipe.

By placing the tailpipe trim on the tool can be a

Tilting the tailpipe trim relative to the tool can be prevented. By manually pushing the tailpipe breech up to a stop on the tailpipe, misalignment of the tailpipe baffle relative to the tailpipe can be prevented. This stop can be formed by moving against the edge of the end rs raw claws. By fixing the tool to the tailpipe, a displacement of the tool relative to the tailpipe during the sliding of the

Tailpipe trim can be prevented on the tailpipe. Thus, the mechanical sliding the tailpipe trim on the tailpipe without

Occurrence of a recoil allows what is the last step of the

Procedure forms. The fixing of the tool and the sliding of the tailpipe aperture by the movement mechanism can be carried out at least partially, in particular completely, at the same time. In the method, the tailpipe baffle can be inserted into a cup-shaped holder of the tool and / or the tool can be fixed to the tailpipe by a spreading mechanism, in particular by a cone and clamping springs. By inserting the tailpipe baffle into a cup-shaped holder, an undesired displacement of the tailpipe baffle in the radial direction or a tilting of the tailpipe baffle relative to the tool can be prevented. Through a

Spreader mechanism in the form of a cone and arranged around the cone clamping springs, the tool can be easily fixed to the tailpipe.

The tool can have security functions, by which activating the movement mechanism only after a certain

Back pressure through the tailpipe trim is possible, or only if an operator holds the tool with both hands. The tool can be designed such that the movement mechanism can only be triggered when a manual sliding on

Threshold of the back pressure on the tailpipe is exceeded.

The spreading mechanism 22 has a cone 24. Further, the spreading mechanism 22 on clamping springs or terminal strips, of which one example is denoted by 26 here. These clamping springs 26 are fixed with a first end 28 on the tool 12, in particular on a motor housing 30 of the tool 12. On the motor housing 30, a first handle 32 is formed. The clamping springs 26 each have a serrated or bent first section 34. This serrated first portion 34 abuts the cone 24. At this first portion 34, a second portion 36 of the respective clamping spring 26 connects, in particular the second end of this clamping spring 26, which is movable, in particular unsecured, formed. This second one

Section 36 may be deflected in the radial direction of the cone 24 to effect attachment of the tool 12 to the tail tube 16.

The clamping device 18 has a cup-shaped or

cylindrical holder 38. In these, the tailpipe 14 can be inserted or inserted. It is then secured along its circumference against tilting or against displacement in the radial direction during the Aufschiebeprozesses. Via a connecting piece 40, the cone 24 is attached to the cup-shaped holder 38, so that the Cone 24 and the cup-shaped holder 38 can be moved together. Then, the spreading mechanism 22 and the

Movement mechanism 20 for moving the tailpipe 14 are activated at the same time.

The movement mechanism 20 and the clamping device 18 have a common drive 42. This drive 42 has a motor (not shown) in the motor housing 30, in particular an electric motor, and a rail 44. On this rail 44, a carriage 46 is arranged axially displaceable. On the carriage 46 of the cup-shaped holder 38 of the clamping device 18 is attached. The inserted into the cup-shaped holder 38 tailpipe 14 can by the carriage 46 and the rail 44 in a straight line in the direction of

Tailpipe 16 are moved. The carriage 46 and the rail 44 form an actuator 48 for pushing the tailpipe.

In the cup-shaped holder 38 is on the end tube 16 axially opposite side a recess as a viewing window 50th

arranged. Through this window 50 can be controlled whether the tailpipe 14 was inserted sufficiently deep to a

Move in the radial direction or to prevent tilting relative to the cup-shaped holder 38.

The tailpipe 14 has claws 52, which serve the attachment of the tailpipe 14 to the tailpipe 16.

In Fig. 2 is a longitudinal section through the mounting assembly 10 at

After inserting the tailpipe 14 in the cup-shaped holder 38, the tailpipe 14 is manually pushed onto the tailpipe 16 until the stop forming part of the claws 52 of the tailpipe 14, the tailpipe 16 touched. The first and second sections 34, 36 of the clamping springs 26 fastened with their first end 28 to the motor housing 30 are then arranged inside the tailpipe 16. However, the respective second section 36 in the form of the second end of the clamping spring 26 does not touch the inner wall 54 of the end tube 16. The serrated first portions 34 of the clamping springs 26 abut against a tapered portion 56 a of the cone, which does not yet have the maximum diameter 58.

In Fig. 3 is a longitudinal section through the mounting assembly 10 after fixing of the tool 12 to the tailpipe 16 is shown. After the manual stop has been reached (see Fig. 2), the

Movement mechanism 20 triggered. The carriage 46 of

Movement mechanism 20 was guided by the drive 42 along the rail 44. As a result, the tailpipe 14 was further pushed onto the tailpipe 16. Simultaneously with the triggering of the

Movement mechanism 20 was the spreading mechanism 22 of the

Tool 12 is activated. The cone 24, which is attached via the connecting piece 40 to the cup-shaped holder 38, deflected the clamping springs 26 radially. The serrated first portion 34 of the respective clamping spring 26 slid along the cone 24 along. The second portion 36 in the form of the second end of the respective clamping spring 26 has been moved toward the inner wall 54 of the tailpipe 16. Finally, the serrated first portions 34 of the clamping springs 26 each reached the area 56b of the

then the second diameter of 58 maximum diameter 58

Section 36 in the form of the second end of the respective clamping spring 26 against the inner wall 54 of the tail pipe 16 is pressed. As a result, the tool 12 has been fixed in position relative to the tailpipe 16 since the clamping springs 26 are fixed with their respective immovable first end 28 to the motor housing 30 of the tool 12. So could one

Recoil by recoil forces during the postponement of

Endrohrblende 14 prevents and the tailpipe 14 - as in Fig. 3rd shown - are completely pushed onto the tailpipe 16.

In Fig. 4, the designated D detail of the mounting assembly 10 in Fig. 3 with a spring heritage loaded projection 62 in the cup-shaped holder 38 is shown enlarged, which is inserted into a drainage hole 64 of the tailpipe 14 for their positioning. This allows the drainage hole 64 to reliably mount downward. In Fig. 5 is a side view of the mounting assembly 10 with the tool 12, the inserted into the cup-shaped holder 38 tailpipe 14 and the tailpipe 16 is shown. At its motor housing 30, the tool 12 may have a tab 66. This tab 66 is the cable guide. In addition, a tether can be guided through this tab 66, which can be guided for support, for example, around the neck or the shoulder of the operator of the tool.

In the Fign. 6, 7, the mounting arrangement 10 is shown with the tool 12, the tailpipe 14 inserted in the cup-shaped holder 38 and the tailpipe 16 in a first and a second isometric view. Shown here is inter alia the viewing window 50 of the cup-shaped holder 38. In particular, next to the first handle 32, a second handle 68 for the operator of the tool 12 can be seen, which is arranged on the rail 44. Thus, the operator can grasp the tool 12 with both hands. In the handles 32, 68 sensors (not shown) may be arranged, which is an actuation of the

Allow actuator 48 only when the user grasps the tool 12 with both hands. After the tailpipe baffle 14 has been fixed to the tailpipe 16, the cone 24 can be moved opposite to the direction in which he was introduced into the tailpipe 16. The cone 24 is then moved backwards out of the tail pipe 16. The serrated first portion 34 of the clamping springs 26 slides along the cone 24 back into its

Starting position before inserting the cone 24 in the tail pipe 16. The deflection of the clamping springs 26 is reduced. As a result, the clamping force of the clamping springs 26 decreases until no fixing effect is present. The tool 12 may then be removed from the tailpipe 16 leaving the tailpipe baffle 14 on the tailpipe 16. FIG. 8 shows a method 100 for mounting a tailpipe baffle 14 on a tailpipe 16 with a tool 12 according to the invention. In a first first step 102, a clamping device 18 of the tool 12 is fixed to an end pipe 16. In a second step 104, a movement mechanism 20 of the tool 12 pushes the

Tailpipe 14 on the tailpipe 16. The first step 102 and the second step 104 can be carried out in particular simultaneously.

Taking a synopsis of all the figures of the drawing, the invention collectively relates to a tool 12 for mounting a tailpipe trim 14 to a tailpipe 16 of a vehicle. By a clamping device 18 of the tool 12 for the tailpipe 14, the tool 12 can be fixed to the tailpipe 16. The tailpipe 14 can be placed on the tool 12. On
