Description

Technical Field

[0001] The utility model relates to the technical field of welding gun cables, in particular to a welding gun cable temperature rise test platform. Background Art

[0002] In modern manufacturing, welding technology, as a key process for joining metal materials, plays a vital role across all industries. Industrial gas shielded welding torches, as efficient, stable, and widely used welding accessories, have become the preferred choice for many companies pursuing high-quality products and improved production efficiency.

[0003] To ensure prolonged use of a welding gun, the amount of heat generated during welding directly impacts its duration and effectiveness. There are two primary sources of heat generation in a welding gun: heat generated by the copper wires in the cable when current flows through them. For a given current, the smaller the square number of copper wires in the cable, the greater the heat generated. Furthermore, the temperature of the handle determines whether the operator can use the welding gun for extended periods of time. This temperature is determined by the compression of the cable and the gun body. A better compression results in less heat generation. Therefore, we often measure the temperature of the cable and the clamping tube to determine if the welding gun meets our requirements.

[0004] In conventional production, the cable specifications, i.e., the square number of copper wires in the cable, can only be confirmed by calculation formulas, and the size of the crimping can be measured to confirm whether the crimping meets the standards. This method is more troublesome and has low accuracy. Utility Model Content

[0008] Furthermore, the constant current source and the load box are arranged outside the temperature rise test bench, close to the cable fixing block.

[0009] Furthermore, the cable testing area is arranged in front of the buckle tube testing area.

[0010] Furthermore, the cable testing area and the buckle tube testing area fix the cable to be tested in sequence.

[0011] Furthermore, the temperature sensor is fixed in the position of the copper wire in the buckle tube and the cable by bundling.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] A welding gun cable temperature rise test platform, such as Figure 1 、 2 As shown, it includes a temperature sensing line 2, a temperature rise test bench 3, a cable fixing block 4, a constant current source 5, a load box 6, a cable test area 7, and a buckle tube test area 8: the temperature rise test bench 3 is provided with a current adjustment and temperature display device 3-1; the cable fixing block 4 is arranged on the upper surface of the temperature rise test bench 3; the cable fixing block 4 is connected to the constant current source 5 and the load box 6; the cable test area 7 and the buckle tube test area 8 are arranged on the temperature rise test bench 3 and are connected to the current adjustment and temperature display device 3-1 in turn; the cable test area 7 and the buckle tube test area 8 are respectively provided with temperature sensors, and the temperature sensors are fixed at the buckle tube 9 of the cable 1 to be tested and the copper wire 10 in the cable.

[0021] Specifically, by precisely arranging the temperature sensing wire 2 in the cable test area 7 and the buckle tube test area 8, combined with the current adjustment and temperature display device 3-1, the temperature rise of the copper wire 10 in the welding gun cable and the buckle tube 9 is monitored in real time and accurately, which solves the inaccuracy problem caused by the traditional method of only using calculation formulas and manual measurements, and ensures the accuracy of the test results. The platform integrates a constant current source 5 and a load box 6, which can simulate the current changes in the actual welding process and automatically perform temperature rise tests. The automated testing method greatly improves the test efficiency, reduces manual intervention and test time, and makes the evaluation of the welding gun cable and buckle performance faster. The design of the temperature rise test bench 3 takes into account the convenience of user operation. The setting of the cable fixing block 4 makes the cable 1 to be tested easy to fix. At the same time, the current adjustment The temperature display device 3-1 provides an intuitive temperature display. Users only need to set the parameters to start the test without complicated operating steps. This test platform ensures consistent conditions for each test through standardized test environment and precise measurement methods, thereby improving the repeatability and reliability of the test results. During use, the cable to be tested is placed flat on the temperature rise test bench, and the front and rear ends are respectively connected to the cable fixing blocks. The temperature sensor is tied to the part that needs to be tested, namely the cable and the buckle; the maximum current ampere of the load box is adjusted according to the current required for the test; turn on the main power, accurately adjust the load current of the temperature rise test bench, and select the required temporary load rate. Generally, the temporary load rate of the gas-cooled protective welding gun is 60%, that is, work for 6 minutes and stop for 4 minutes. Finally, observe the temperature changes and make records.

[0022] As a preferred embodiment of the above, Figure 1 As shown, two cable fixing blocks 4 are arranged on the same side of the temperature rise test bench 3 .

[0023] Specifically, by installing fixing blocks 4 at each end of the cable, the cable can be stably secured during testing. This dual-end fixing method effectively prevents errors caused by uneven force or cable movement during testing, improving test accuracy and reliability. By adjusting the distance between the two cable fixing blocks 4, the test platform can adapt to testing welding gun cables of different lengths. This flexibility makes the test platform more applicable and can meet the testing needs of different users with different cable lengths.

[0024] As a preferred embodiment of the above, Figure 1 As shown, the constant current source 5 and the load box 6 are arranged outside the temperature rise test bench 3 , close to the cable fixing block 4 .

[0025] Specifically, by placing the constant current source 5 and the load box 6 outside the test bench, the space around the test bench can be effectively utilized to avoid occupying too much table area. In this way, the test bench can be more focused on the fixing and testing operations of the cables, improving the cleanliness and operational convenience of the entire test area. Placing the constant current source 5 and the load box 6 close to the cable fixing block 4 can shorten the connection distance between the cable and these devices, reduce signal attenuation and energy loss, and at the same time, this layout also facilitates operators to quickly connect cables, adjust parameters and monitor the test process, thereby improving work efficiency.

[0026] As a preferred embodiment of the above, Figure 1 As shown, the cable testing area 7 is arranged in front of the buckle tube testing area 8.

[0027] As a preferred embodiment of the above, Figure 1 As shown, the cable testing area 7 and the tube testing area 8 fix the cable 1 to be tested in sequence.

[0028] Specifically, the cable test area 7 is set in front of the buckle tube test area 8, and the cable test area 7 and the buckle tube test area 8 fix the cable to be tested 1 in sequence, so that the cable test area 7 is placed in front of the buckle tube test area 8. During the test process, the movement of the cable may introduce additional errors. By setting the cable test area 7 and the buckle tube test area 8 as continuous areas and fixing the cable to be tested 1 in sequence, the number of times and distances the cable moves during the test can be reduced, thereby reducing the impact on the test results.

[0029] As a preferred embodiment of the above, Figure 2 As shown, the temperature sensor is fixed in the position of the buckle tube 9 and the copper wire 10 in the cable by bundling.

[0030] Specifically, the bundling method ensures close contact between the temperature sensor, the buckle tube 9, and the copper wire 10 within the cable, enabling accurate temperature measurement of these critical locations. This direct contact reduces heat loss and errors during heat conduction, improving temperature measurement accuracy and preventing the temperature sensor from loosening or falling off during testing, ensuring continuity and stability of the test. Even when the cable is subjected to tension or vibration, the temperature sensor remains securely fixed, ensuring the reliability of test results.

[0031] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
