Description

The invention relates to a test device for a welding hose package for connecting components of a welding device and a test system with such a testing device and a welding hose package.

Out DE 20 2010 006 125 U1 a test device for a welding hose package is known. In this test device, the welding hose package must be connected to a standard connection in order to carry out a measurement on a switch of the welding hose package using an internal continuity tester. A control voltage of 24 V is applied via the standard connection to the welding hose package and then to a lamp and an acoustic detector. In order to carry out a continuity test on a main cable (power / water cable) of the welding hose package, the control voltage is applied to a measuring line in order to allow the current to flow via the main cable to the lamp and acoustic alarm. The gas hose and the water hoses of the welding hose package can also be tested using an additional attachment. The gas hose is filled with compressed air, whereby there is a primary and secondary gas flow meter to compare the incoming and outgoing gas quantities and thus to determine a leak. The water hoses are first rinsed with 4 bar water pressure, after which a secondary shut-off valve is closed. As soon as 4 a primary shut-off valve is also closed. A pressure drop and thus a leak in the water hose can be recognized by means of a pressure gauge which indicates the water pressure.

Due to the one-sided connection of the welding hose package to the standard connection, the separate measuring line is required to check the continuity of the main cable of the welding hose package. Furthermore, the separate connection of these to the additional attachment is required to check the fluid lines of the welding hose package. This makes it difficult to connect and therefore test a welding hose package.

The object of the invention is to provide a test device for a welding hose package and a test system with such a testing device and a welding hose package, so that the effort for connecting the welding hose package is reduced.

This is achieved with a test device according to claim 1 or a test system according to claim 10. Further developments of the test device according to the invention are defined in the dependent claims.

According to the invention, a test device for a welding hose package is provided, in which at least an integrated control current line, a welding current line and a fluid line are integrated. The lines of the welding hose package open out at a supply-side longitudinal end thereof in a first coupling device with a control current line coupling, a welding current line coupling and a fluid line coupling and at a working side end thereof in a second coupling device with a control current line coupling, a welding current line coupling and a fluid line coupling.

The test device according to the invention has at least one primary-side coupling device, at least one secondary-side coupling device, a test device and an evaluation device.

The primary-side coupling device is used to couple one of the first and second coupling devices of the welding hose package and comprises at least one control current line coupling, one welding current line coupling and one fluid line coupling. The secondary-side coupling device serves to couple the other of the first and second coupling devices of the welding hose package and comprises at least one control current line coupling, one welding current line coupling and one fluid line coupling.

The test device is connected between the at least one primary-side coupling device and the at least one secondary-side coupling device in order to apply a first electrical test voltage (for example 24 V DC) between their control current line couplings, a second electrical test voltage (for example 24 V DC) between their welding current line couplings and a fluid pressure difference (for example 4 bar) between their fluid line couplings.

The evaluation device is connected to the test device and is set up to evaluate, when the welded hose package is coupled, based on the first and second test voltages, the respective test current flows through the welded hose package and a fluid flow through the welded hose package based on the fluid pressure difference, and to output respective evaluation results.

Due to the complete connection of the welding hose package to the test device by means of the respective coupling devices on both sides and with regard to the integrated lines (power lines, fluid lines), no separate measuring line or an additional structure is required Welding hose package can be connected to check this. This results in less effort for connecting the welding hose package.

To output the evaluation results, the evaluation device preferably has a visualization device and in particular a display screen. The evaluation device is preferably set up in such a way that, within the scope of the evaluation results, it specifies whether the respective line of the welding hose package is faultless or not, and indicates the exact fault when a fault is determined.

The primary-side and secondary-side coupling devices as well as the test device and the evaluation device are preferably integrated in a common housing. This means that the test device is compact and therefore easy and safe to use.

According to one embodiment of the test device according to the invention, the test device is set up to provide the first and the second test voltage in each case in order to carry out both a continuity test and a line break test for the control current line and the welding current line when the welding hose package is coupled.

This test configuration can also advantageously detect a line break in the welding hose package, which would not be recognized in a normal continuity test if there is still electrical contact at the break point. A line break can e.g. through increased line resistance or reduced current flow (at the break point).

According to a further embodiment of the test device according to the invention, the test device is set up to provide the second test voltage (e.g. 55 V direct current) for carrying out a welding load test when the welding hose package is coupled, and has a load resistance for carrying out the welding load test. The load resistance and the correspondingly high test current (e.g. 20 A to 1500 A) advantageously simulate the conditions during a welding process.

According to another embodiment of the test device according to the invention, the test device is set up to provide the fluid pressure difference in order to carry out both a passage test and a leak test for the fluid line when the welded hose package is coupled.

According to yet another embodiment of the test device according to the invention, at least one of the primary-side coupling device and the secondary-side coupling device is designed as a multiple coupling for simultaneous coupling of the control current line coupling, welding current line coupling and fluid line coupling integrated in a suitable multiple coupling counterpart as a coupling device from one of the first and second coupling devices of the welding hose package.

By providing a multiple coupling pair, the connection of several and preferably all of the lines of a hose package can be implemented with a single insertion process, which further reduces the effort for connecting the welding hose package. Such multiple coupling pairings are commercially available e.g. distributed by Harting Deutschland GmbH & Co. KG from Minden under the trade name Han-Modular®.

According to another embodiment of the test device according to the invention, the welding hose package has at least one further fluid line with respective further fluid line couplings on the supply-side and on the working-side longitudinal end of the welding hose package. The further fluid line coupling of one of the first and second coupling devices of the welding hose package is integrated into the multiple coupling counterpart as a coupling device. In addition, the at least one primary-side coupling device and the at least one secondary-side coupling device each comprise at least one further fluid line coupling for coupling in each case one of the further fluid line couplings of the first and second coupling devices of the welding hose package. The at least one further fluid line coupling of the at least one of the primary-side coupling device and the secondary-side coupling device is integrated into the multiple coupling.

In this case, the test device is advantageously set up to test a connection assignment of the fluid lines of the welding hose package to its fluid line couplings on the supply-side and on the working-side longitudinal end when the welding hose package is coupled. This can prevent a fluid (such as compressed air or welding gas or protective gas) that is introduced into the welding hose package at the correct fluid line coupling at the supply-side longitudinal end from being emitted at the wrong fluid line coupling at the working longitudinal end of the welding hose package and thus, e.g. during welding. Compressed air incorrectly flows out as a protective gas.

According to one embodiment of the test device according to the invention, this preferably has a control device in the above-mentioned common housing, in which the test device and the evaluation device are integrated, so that when the welded hose package is coupled, both a manually controlled and an automatic test and output of the evaluation results can be implemented. For this purpose, the control device preferably has a programmable logic control unit.

According to a further embodiment of the test device according to the invention, there are a plurality of primary-side coupling devices, such as the at least one primary-side coupling device, which differ in terms of a respective number of their control current line couplings, welding current line couplings and / or fluid line couplings and / or with regard to an arrangement pattern of their control current line couplings, welding current line couplings and / or fluid line couplings, and a plurality of secondary-side coupling devices, such as the at least one secondary-side coupling device, are provided, which differ with regard to the respective number of their control current line couplings, welding current line couplings and / or fluid line couplings and / or with regard to an arrangement pattern of their control current line couplings, welding current line couplings and / or fluid line couplings.

In this way, differently configured welding hose packages can be tested with the test device according to the invention.

Another advantage of the test device according to the invention is the possible visualization of the test results and their exact assignment to individual welding hose packages by means of a suitable reading device, e.g. a suitable scanner, which enables an associated logging of the test result. For this purpose, the welding hose packages to be measured have a coding, e.g. a barcode that is scanned on the test device using a compatible scanner. The test result is then assigned and saved exactly to a hose package based on the code stored in a corresponding database and can be output immediately or later in a corresponding test protocol. Corresponding connections (USB, network, etc.) are preferably provided on the test device for this purpose.

In addition to the name / number of the hose package and the associated test result, this protocol can also contain the article or part number of the hose package, the date and time of the test and, if applicable, the tester and / or the test system.

A further advantage of the test device can be achieved if, in addition to checking the hose package, middle I (hardware and software) are also provided on the test device, which also make it possible to check the welding head.

An improved test result can be achieved by checking the polarity of the control line so that wiring errors can be reliably detected.

Another and significant advantage is the mobility of the test device, which allows the corresponding tests to be carried out on site and thus to avoid extensive dismantling activities. This is made possible in a simple manner in that the test device can be moved by appropriate means. For this, e.g. Wheels or rollers can be provided on the test device.

The invention also provides a test system with a test device and a welding hose package according to one, several or all of the previously described embodiments of the invention in any conceivable combination, the first and second coupling devices of the welding hose package being connected to one of the primary and secondary coupling devices of the test device are coupled.
