Description

Device for arranging a mechanical holding member

The present invention relates to a device for arranging a mechanical retaining element, an arrangement for fastening or pressing a clamp, bracket or a press ring, a use of the device or arrangement for arranging, clamping or pressing clamps, clamps, clamps or press rings and a method for the controlled and monitored arrangement of a mechanical holding member.

In the course of company certifications, for example according to ISO9000, ISO9001, ISO9002 etc. as well as other standards, the aspect of quality control or assurance and monitoring of production and assembly processes is given increased importance.

In the machine and automotive industries in particular, it is important that every component or component meets certain quality standards with regard to the quality of the materials and the assembly of the parts. In addition, it is also important, in addition to the material data, the assembly process at any time, i.e. to be able to check and understand them at a later date. This is particularly the case if damage or accidents occur, so that any defective parts or defective assembly can be determined to clarify whether this was the cause of the damage or the accident.

Material data has been recorded for a long time, be it by specifying the production data, so-called "batch data or batch data", or by production units, or by referring to quality records, journals and the like. On the other hand, information about the assembly is often missing, in particular when assembling several components which are held together, assembled or connected to one another by means of mechanical holding means, such as clamps, clips and the like.

It is therefore an object of the present invention to propose a device and a method for controlling the assembly or quality control during assembly, in particular of production or machining processes carried out using mechanical holding means such as clips, clamps, press rings and the like or monitor and record if necessary.

According to the invention, the object is achieved by means of a device according to the wording according to claim 1, by means of an arrangement according to the wording according to claim 10 and by means of a method according to the wording according to claim 16.

It is proposed that the device according to the invention for arranging a mechanical holding member has on the one hand first means for setting, limiting and / or measuring a distance or a length or distance which is covered or overcome when the holding member is arranged and / or can be ascertained on the holding member , and second means for setting, limiting and / or measuring at least one force component on the holding element, which force component is built up when covering or covering the distance on the holding element or by the holding element.

According to a further embodiment variant, at least one drive is provided and at least one processing element connected to the drive for arranging the holding element, the first means for setting, limiting and / or measuring sen are connected to the drive and / or the processing element in such a way that a distance or distance is covered or covered on the holding element during the processing process and / or the drive is interrupted when a certain length or distance is measured or recorded on the holding element .

It is further provided that the second means for setting, limiting and / or measuring at least one force component are connected to the processing element and / or the holding element in such a way that at least one holding force or restoring force which arises on the holding element during the arrangement can be measured.

Furthermore, an actuator for controlling and monitoring the first means for the controlled execution of the machining process is proposed, as well as a further actuator for limiting the force component built up during the machining process at a maximum value. In addition, target / actual comparison arrangements are provided, on the one hand to compare the target value transmitted to the first means with the effective length or distance covered or overcome or measured on the holding element, and to compare the force component effectively measured at the end of the machining process on the machining element to compare with the corresponding setpoint.

In a control, measurement and test arrangement, on the one hand, the machining process is controlled and monitored by means of correspondingly entered setting values or setpoints and, on the other hand, the actual values determined or measured on the machining element during or after the machining process is recorded and with the corresponding setpoints compared, whereby if the actual values do not match the nominal values - 4 -

deviations are pointed out within certain tolerance ranges by means of display elements, such as optical or acoustic displays or signals.

Further preferred embodiment variants of the device according to the invention are characterized in the dependent claims.

Also proposed is an arrangement for fastening or pressing a clamp, bracket or a press ring, comprising an apparatus according to the invention. The proposed arrangement is particularly suitable for arranging, clamping or pressing clamps, clips, clamping rings or press rings when creating hose or pipe connections, when connecting hoses and pipes to, for example, a connecting nipple, when arranging protective bellows and the like, and also for arranging or fastening pipes, cables, hoses in engines, machines and the like.

Also proposed is a method for the controlled and monitored arrangement of a mechanical holding element, wherein when arranging or processing the holding element, a previously defined machining path is covered or overcome and / or the machining process is ended if on

Retaining member a predetermined length or distance is measured. Furthermore, a force component is measured on the holding element, which is built up during the machining process.

After completion of the machining process, both the effectively covered distance or length or distance are measured and the force component effectively built up during the machining process, which values are compared with corresponding target values within certain tolerance ranges, where - 5 -

if the actual and setpoint values do not match, the process is shown as unsuccessful.

Preferably, both setpoints and actual values are set or recorded in an electronic control, measurement and test arrangement, by means of which arrangement the machining process is controlled on the one hand and the setpoint / actual comparison is carried out on the other hand, and in the end the arrangement is preferably or storage means coupled to the arrangement are provided, in which both the target and the actual values for the respective machining process are recorded, so that the machining process can also be checked or understood at a later point in time.

The invention will now be explained in more detail, for example, and with reference to the accompanying figures.

6 and 6a, a pressing tool, shown schematically, in

Longitudinal section, for pressing a press ring and

FIG. 7 the pressing tool from FIG. 6 in the open state.

Fig. 1 shows schematically an arrangement for the controlled and verifiable arrangement of a clamping ring, for example when arranging a plastic or rubber hose on a connecting nipple, or for the production of a pipe-hose connection, for example in hydraulics or in automobiles.

Various processing parameters can be set and checked on a control, measuring and testing arrangement 1, which are essential when arranging a clamp or clamp 33 so that the hose nipple or. Hose-pipe connection can be created reliably in accordance with the required quality standards. Various lengths or distance values 3 can initially be set on the arrangement 1, for example in order to be able to determine the distance covered during processing or by a length or a distance on the arranged clamp or strap. The arrangement 1 further includes setting options for tolerance values 5, within which the distance or length or distance can vary. On the display 9, the effectively covered path or the measured ne length or distance 9 is displayed, on the basis of which display a further display 7, for example visually, shows whether the set or predetermined target value 3 has been reached within the tolerances 5 during the machining process or not. For example, the displays 7 can have red and green lamps, green lighting up in the positive case and red in the negative case. Of course, acoustic signals can also be provided so that it is immediately apparent whether the setpoint has been reached.

In addition, various adjustment buttons 11 are arranged, by means of which the operating conditions during processing can be set. So the processing speed, the reset speed, etc. can be selected with the adjusting buttons 11.

An input 13 is also provided in order to set the desired value of the clamping force or restoring force to be achieved on the clamping ring or the clamps during the machining process. Again, a tolerance quantity 15 is provided as well as displays 17, on which it is shown whether the value shown in the display 19 and measured on the clamping ring or the bracket corresponds to the target value 13.

Via an electrical line 25 and a pneumatic control line 27, the arrangement 1 now controls the clamping pliers 29, which have two pliers jaws or pliers legs 31 on their front side, for carrying out the processing or fixing operation of the clamp 33 for attaching a hose 37 to a pipe or pipe nipple 39.

In Fig. 2, the clamping pliers 29 is shown enlarged, for example on the back of this clamping pliers 29 a trigger - 8th -

button 26 can be provided to trigger the clamping or pressing operation. Of course, the triggering or carrying out of the clamping or pressing process can also be carried out by a corresponding control on the arrangement 1, or the triggering can take place automatically periodically, in particular if it is an automated or robot-like mode of operation.

One or more pressure pistons or pressure cylinders are arranged in the front area 30 of the clamping pliers 29 (not shown), as is generally known from the prior art for operating a clamping pliers. By means of these pistons or cylinders, a clamping wedge 32 is actuated in a longitudinally displaceable manner, which drives two rollers 38 apart when moving forward, which, respectively, for the joining together. Drifting apart of the two pliers legs 31 is responsible. These jaws 31 are held in the processing head 40 by means of bolts 42.

3, the machining head 40 is enlarged and shown in the exploded state, the longitudinal wedge 32 being shown protruding from the front section 30. In order for the longitudinal wedge 32 to be driven back into the front section 30 after it has been driven forward, a spacer bush 36 is arranged on the one hand and a return spring 34 abutting the spacer bush.

By driving the wedge 32 forward, the two rollers 38 and thus the clamping legs 31 are driven together, which, as already explained with reference to FIG. 2, are held on cams or pins 42.

The machining process according to the invention is shown schematically with reference to FIGS. 3a to 3d. 3a shows the two pliers legs 31 in the starting position, ie spaced apart by the value a. By actuating the clamp pliers 29, the two clamp legs 31 are driven together, as shown in FIG. 3b. By means of the control, measuring and test arrangement it can now be entered that after machining a clamping ring or a clamp the two clamping legs 31 are driven together to an end distance b. However, the path traveled by the two clamping legs 31, ie the value ab, can also be entered.

By pressing together, for example, an ear area 35 of a clamping ring, respectively. An ear clip 33, as shown in FIG. 3 c, of course generates a restoring or clamping force which acts on the two clamping legs 31. In the initial state, as shown in Fig. 3c, the force Kl, which acts on the two clamping legs 31 through the ear 35, is practically zero.

By pressing the two clamping legs 31, the ear 35 is deformed or. the clamping ring 33 is pressed together to such an extent that a hose is firmly arranged on a bracket. This compression of the ear 35 now creates a restoring force K3, which is generated on the one hand by the deformation and in particular by the clamping action of the clamp 33 on the outer surface of the hose (not shown). It is now essential that the two clamping legs 31 are driven together until their distance is equal to b, which has been predetermined by the control, measuring and testing arrangement. Now the restoring force K3 is also measured and compared with the setpoint 13 entered in the arrangement 1. If both value b (or ab) and the value K3 with the respective setpoints 3 or 13 within the - 10 -

Tolerance ranges 5 and 15 match, the pressing or clamping process has been successfully carried out. In other words, it can be assumed that a hose, for example to be arranged on a nipple or a pipe, has been properly arranged or pressed in accordance with predetermined quality standards. Of course, this always presupposes that the pipes or nipples and hoses used are within the required quality standards, i.e. that both the material and the dimensions of the materials to be connected or pressed meet certain requirements.

Finally, it is now possible to save the actual values measured during the pressing or clamping process, as well as the setpoint on which the process is based, and to assign them to a respective process carried out. This makes it possible to determine at a later point in time whether the clamping or pressing process has been carried out correctly or not. It would of course be advantageous if any incorrectly executed pressing or clamping processes were reported or visualized or made acoustically noticeable so that inadequate connections or clamping or pressing processes can be removed from a production process immediately.

Finally, the control, measuring and testing arrangement 1 according to FIG. 1 is shown enlarged in FIG. 4, ie the various setting buttons and displays are now clearly recognizable. For example, the distance b can be set at the setpoint 3, the starting position a of the pliers legs 31 and also a so-called holding position a ', in which, for example, the clamping ear 35 shown in FIG. 3c can already be held. This holding position is particularly important for robot processing, where a robot - left

Terarm, comprising the pipe wrench, initially engages a clamp 33 on the ear 35 from a supply, this clamp 33 is moved away by pivoting the robot arm and placed over a pipe or hose, which in turn is automatically put over a nipple or another pipe , then the process according to the invention for arranging the clamping ring or the clamp is then carried out automatically. The robot arm is then automatically swiveled away again in order to carry out another machining operation.

Corresponding tolerance values 5 can be set for all three adjustable target values 3. In addition to the setting of the tolerance values, a display 7 is provided, which shows whether the entered target value is being maintained or not. The value measured on the clamping ring or the clamp is shown on a display 9. With the adjusting buttons 11, the pressing speed can be adjusted, i.e. the speed at which the wedge 33 is driven forward in order to actuate the two clamping jaws or clamping wedges 31. Correspondingly, a setting is also provided by means of which the re-opening or retraction of the clamping wedge 32 can be adjusted.

As already explained with reference to FIG. 1, setpoints 13 can be entered for the force to be achieved or set, whereby on the one hand the final clamping force K3 to be achieved and the maximum pressing force to be applied during the clamping process can be set. Once again, the tolerance can be set, and displays 17 can be used to determine whether the actual values correspond to the target values. The actual value is again shown on a display 19. - 12 -

The arrangement also includes adjusting buttons 21, by means of which the operating mode can be set, i.e. whether, for example, the intermediate holding step is inserted during assembly or whether the pliers directly carry out the movement from distance a to distance b.

Finally, a display 23 finally shows whether the entire clamping or pressing process has been successfully or not successfully completed.

At the rear of the arrangement 1, a plug device 24 is provided, on which the pressure and control lines 25 and 27 can be arranged. This plug-in device 24 or the corresponding plug can be coded, so that when setpoints are entered in the arrangement 1, only one pair of clamping pliers corresponding to these setpoints can be inserted.

5, the clamping or pressing process is shown in diagram form, line 51 representing the pliers travel during assembly and line 53 the clamping force generated between the pliers by the clamping ring or pressing ring. In area P, ear 35 is clamped or pressed together, as shown in FIGS. 3c and 3d. The two pliers jaws 31 cover the path shown in FIG. 5 until the two pliers tips have approached, for example, 2.5 mm. Then the machining process is interrupted, the force component 53 also being measured in this area P at the same time. It clearly shows that the power build-up when

Clamping takes place with a slight delay, ie when the distance of 2.5 mm, for example, is reached, the final clamping force has not yet been reached. Ultimately, however, a clamping force of, for example, 1.0 kN builds up, which then - 13 -

is then compared with the corresponding setpoint in the arrangement 1. If the two values match within the required tolerance, the assembly process is assessed as successfully completed.

6 shows a further example of a processing element for arranging a press ring, for example. It is a circular pressing arrangement 61, suitable for arranging a pressing ring, for example in order to slip a rubber bellows over a cardan shaft, such as in automobile construction, and to arrange it firmly. 6 shows the assembly arrangement 61 for the press ring in longitudinal section and FIG. 6a in top view, wherein a connection 63 is again provided for the actuation of the assembly arrangement, for connecting the assembly arrangement to the control, for example via electrical lines and via a hydraulic line .

Controlled actuation of the assembly arrangement, for example hydraulically or pneumatically driven, moves a guide block 65 in the direction of the arrow, as a result of which two cams 67 are moved within a corresponding slot or a saving. By moving the two cams 67, two mutually separate circular halves 69 'and 69''of the pressing tool are moved in the direction of the arrow 76, as a result of which 73 cams 71 are moved in the direction of the arrow 68 in slots. As a result, the pressing jaws 70 are in turn driven radially inward in the direction of arrow 68. A pressing ring arranged in this way within the pressing jaws 70 is pressed or pressed evenly, for example on the above-mentioned rubber bellows, in order to firmly connect the bellows to a drive shaft, for example. - 14 -

So that a press ring can be introduced together with the materials to be connected or pressed within the pressing tool, the two semicircular parts 69 'and 69' 'can be opened, as shown schematically in FIG. 7.

The arrangements, Kiemmund pressing tools shown in FIGS. 1 to 7 are of course only examples which are intended to serve to explain the present invention in more detail. Basically, it is a matter of any type of mechanical holding or fastening means, the device or arrangement and the method defined according to the invention being particularly suitable for arranging clamps, clamping rings, press rings, clips, cable ties and the like. In this context, reference is made, among other things, to terminals, as described, for example, in EP 570 742, EP 591

648, EP 503 609, CH 561 383, CH 555 026, CH 669 642 and CH 677 010. Ear clips and earless clips are also known from a large number of other patents. With regard to a press ring, reference is made, inter alia, to CH 679 945 and EP 543 338.

Reference is also made to EP 591 648 for the functioning of a clamp.

The above-mentioned invention enables the monitored and regulated arrangement, clamping and pressing of any holding and fastening means, the drive being able to be carried out pneumatically, hydraulically and electromechanically. Regarding measurement technology, sensors, electronic control ect. it should also be mentioned that this is per se - 15 -

techniques and known knowledge that is not dealt with here.

Finally, for example, the operation of an ear clamp, as it can be selected in connection with the clamp, shown in FIGS. 1 to 4, is explained.

A standing electropneumatic pliers, based on the clamping pliers 29, as shown in FIG. 1, is equipped with sensors and control and evaluation electronics in order to be able to adjust the physical parameters of the clamping position, the clamping movement and the force in an adjustable manner.

The detected physical quantities can be compared with the set values on the display 1 (FIG. 1, FIG. 4), and evaluation information can be derived as a result of the comparison.

The e.g. Standing pneumatic pliers are cascaded

Control from a higher priority path control and a subordinate force control. The forceps control is an indirect control based on a pressure control, because force = f (inlet pressure x cylinder area).

In the initial state (a), as shown for example in FIG. 3a, the clamp opening position can assume any position via a displacement control loop. An optimal state is when the forceps opening position is slightly larger than the ear 35 of the ear clip 33. Two operating modes can be selected from this position for pressing the ear.

1. Pressing to a pressing position with specification of the set pressing force. After firing, the pliers shoot - 16 -

according to their speed specification, from the clamp opening position a to the pressing position b.

The force control loop monitors the force curve at all times and prevents the maximum force from being exceeded. If the maximum force is reached, this force is either continued to be pressed until the set path has been reached or, if this is not possible, the pliers remain in their position. If the force is not reached in accordance with the specification, the pliers close to the pressing position.

2.1 Stopping when holding the ear clip a 'with an adjustable holding force.

2.2 Pressing to a pressing position with specification of the set pressing force. After triggering a, the gun closes from the gun opening position to the holding position a 'according to its speed specification.

This holding position is not a predetermined size, but results when a holding force is reached, which must be such that it holds the ear without deforming it.

A further trigger closes the pliers from the holding position to the pressing position b according to their speed specification.

The force control loop monitors the force curve at all times and prevents the maximum from being exceeded

Force. If the maximum force is reached, this force is either continued to be pressed until the set path is reached or, if this is not possible, the pressure remains - 17 -

Pliers are in their position. If the force is not reached in accordance with the specification, the pliers close to the pressing position b.

An optimal pressing is achieved when the ear has reached a pressing position corresponding to the data sheet while applying a defined pressing force.

To check these values, tolerance and time monitors are available, which o.k. Signal 23, a non-o.k. if the specification is exceeded or not reached. Generate signal 23. The physical quantities of the path and the force are also available alphanumerically 9, 19 at an interface.

DECLARATION REFERRED TO IN ARTICLE 19

With regard to the claims originally filed, various documents were identified in the international search, which are classified as harmful to novelty.

Accordingly, the original claims were revised to the effect that they relate specifically to the arrangement of clamps, clips, cable ties or press rings, with the aid of a clamping or pressing element proposed according to the invention, comprising clamping jaws for arranging the mentioned holding elements, such as the clamp, Bride, the cable tie or the press ring. The arrangement thus proposed according to the invention cannot be found in the documents cited in the search report. The four documents EP 0 463 530, DE 40 14 221, DE 40 38 653 and DE 298 06 179 all describe devices, methods and quality assurance methods in connection with the crimping or shrinking on, for example, of clamping rings in fittings, usually clamping or compression rings can be shrunk using clamping jaws. However, the control system described in the various publications is not designed in this way or is suitable for meeting the requirements placed today on the fastening of clamping rings, for example, on account of the various standards or certification procedures.
