Description

Technical Field

[0001] The utility model relates to the technical field of electrical test equipment, in particular to an electrical test equipment for a welding detection platform. Background Art

[0002] In the field of locomotive and vehicle manufacturing, welding technology occupies a vital position. The assembly of locomotive and vehicle bodies, frames, and many key components often relies on high-quality welding connections. The welding quality is directly related to the safety, stability, and overall performance of train operation. With the continuous development of the railway transportation industry, the precision and quality requirements for locomotive and vehicle manufacturing are increasing day by day. In order to achieve precise control of welding quality, electrical test tools have come into being. This kind of electrical test tool is designed to simulate the electrical characteristics under actual welding conditions. By performing comprehensive and detailed electrical performance testing on welding equipment and welding joints, possible welding defects, electrical faults, etc. can be discovered in advance, providing strong data support and testing means for optimizing welding processes and ensuring the welding quality of locomotives and vehicles.

[0003] Traditional electrical test equipment mainly uses conventional multimeters and other general electrical testing instruments for testing. The operator manually touches the test contact with the welding part of the weldment or the relevant circuit connection points of the welding equipment, and reads the basic electrical parameters such as voltage and current displayed by the multimeter to judge the electrical performance of the weld.

[0004] However, there is a prominent problem with these existing traditional detection methods, that is, during the detection process, the detection contacts are very easy to break due to external forces, affecting the normal progress of the detection work. In the locomotive vehicle welding detection scenario, since the welds are usually large in size and complex in shape, the detection contacts need to be moved frequently during detection to cover different parts for comprehensive detection. In this process, the detection contacts will collide with the weld itself, surrounding detection equipment and other external forces, and the existing detection tools and operating methods do not have corresponding protection measures. Once the detection contacts are broken, it will not only lead to detection interruption and increase detection cost and time, but also hinder the accurate evaluation of the electrical performance of locomotive vehicle welding due to the inability to obtain complete detection data in a timely and accurate manner, thereby affecting the effective control of welding quality. For this reason, a welding detection platform test tool is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a welding inspection platform electrical test tool, which aims to improve the problem in the existing technology that the detection contacts are easily broken due to accidental collisions with external forces such as the weldment itself, surrounding detection equipment, etc. during frequent movement and detection.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a welding inspection platform electrical test tool, including a support platform 1 and a connecting block 6. The support platform 1 serves as the basis of the entire tooling, and a plurality of key components are fixedly connected to its top to provide stable support and fixation for it. The top of the support platform 1 is fixedly connected to a fixing seat 2 for stabilizing and supporting the inspection workpiece to ensure that the equipment has good stability during operation. The top of the support platform 1 is fixedly connected to a baffle 3 for preventing splashes during the inspection process and ensuring the safety of the operator. The top of the support platform 1 is fixedly connected to a slide rail 4, and a slide column 5 is slidably connected to the outer surface of the slide rail 4. The slide rail 4 provides a guide for the movement of the slide column 5, so that the slide column 5 can slide smoothly on its outer surface, which is convenient for adjustment to different positions. A detection component is provided inside the connecting block 6, and the detection component is used to perform live detection on the workpiece;

[0033] The detection component includes a test probe 10, which is slidably connected to the inside of the connecting block 6. The test probe 10 is connected in a sliding manner inside the connecting block 6 and can flexibly respond to different test requirements. A placement groove 7 is provided inside the connecting block 6 to provide necessary conditions when the test probe 10 is squeezed. One end of the test probe 10 is fixedly connected to a limiting column 9 to prevent the spring 8 from excessive movement and deformation. The outer wall of the limiting column 9 is provided with a spring 8, which provides necessary elastic buffering to avoid sudden impact of the test probe 10 when it contacts the workpiece, and can also provide a certain restoring force when the probe returns, thereby improving the service life. One end of the spring 8 is fixedly connected to the bottom end of the test probe 10, and the other end is fixedly connected to the inside of the connecting block 6. An adjustment component is provided on one side of the sliding column 5, and the adjustment component is used to perform multi-directional adjustment movement of the test probe 10.

[0034] Specifically, when it is necessary to perform live testing on a large number of different workpieces in sequence in a short period of time, the test probe 10 needs to be frequently moved between the workpieces, and its position and angle need to be adjusted. This high-intensity and frequent operation makes the test probe 10 very easy to be damaged due to accidental collision with the edge of the workpiece, surrounding equipment, or external forces such as pulling when the operator moves quickly. When external force acts on the test probe 10, the internal spring 8 can effectively absorb and disperse most of the force. The purpose of this is to prevent the test probe 10 from being broken by excessive impact during frequent position switching, thereby ensuring its integrity and reliability. The connecting block 6 plays a key connecting role. It not only bears external force, but also provides a stable support structure for the spring 8, so that it can maintain high efficiency in a complex operating environment, minimize the risk of equipment damage, and improve work efficiency.

[0035] Reference Figure 4 and Figure 5 The adjusting component includes a connecting disk 11 and a support rod 12. The bottom of the connecting disk 11 is fixedly connected to one side of the sliding column 5, so that it can maintain a stable position during the movement of the sliding column 5, ensuring that no displacement or shaking occurs during the adjustment process. The support rod 12 is fixedly connected to the top of the connecting disk 11. The support rod 12 is fixedly connected to the inside of the support rod 12. The output end of the motor 13 is fixedly connected to the transmission column 14. The transmission column 14 enables it to effectively transmit the rotational power of the motor 13, further driving the test probe 10 to move synchronously. The top of the connecting disk 11 is fixedly connected to a left-right symmetrical electric push rod 15. The arrangement of the left-right symmetrical electric push rod 15 ensures that force can be evenly applied during the adjustment process, avoiding structural imbalance caused by excessive force on one side. The output end of the electric push rod 15 is fixedly connected to a transmission ring 16. The transmission ring 16 enables it to achieve precise force transmission and provides multi-directional adjustment capability through connection with the bending rod 20.

[0036] Specifically, when faced with workpieces with irregular shapes and special geometric structures, the design of the slide post 5 enables it to slide smoothly on the outer surface of the slide rail 4, thereby allowing the test probe 10 to move flexibly in the horizontal direction. The slide rail 4 provides a stable guide channel to ensure the smooth movement of the slide post 5. At the same time, the output end of the electric push rod 15 plays an important role. It drives the movement of the transmission ring 16 through up and down movement. The transmission ring 16 not only enables vertical movement, but also has a slide groove 17 inside it, which is cleverly combined with the fixed ball 21. The curved shape of the fixed ball 21 ensures that it can flexibly follow the movement of the transmission ring 16, so that the fixed ball 21 can slide smoothly in the slide groove 17.

[0037] Reference Figure 4 and Figure 5, a slide groove 17 is opened inside the transmission ring 16, and the slide groove 17 is intended to provide a guide for the movement of the fixed ball 21 so that it can slide smoothly in the ring. The shape and size of the slide groove 17 have been calculated to ensure that the fixed ball 21 remains stable during the movement and will not deviate from the predetermined trajectory. One end of the transmission column 14 is fixedly connected to a collar 18, and the inner wall of the collar 18 is rotatably connected to a connecting rod 19. The inner wall of the collar 18 is connected to the connecting rod 19 in a rotating connection, allowing the connecting rod 19 to rotate freely in the collar 18, thereby achieving more flexible movement adjustment. The outer wall of the connecting rod 19 is fixedly connected to a curved rod 20. The shape of the curved rod 20 is designed so that it can effectively transmit force and movement under limited space conditions. A fixed ball 21 is fixedly connected to one end of the curved rod 20. The diameter and shape of the fixed ball 21 are optimized to ensure that it can fit tightly inside the slide groove 17 while being able to slide freely. The fixed ball 21 slides inside the slide groove 17.

[0038] Specifically, as the fixed ball 21 moves, the connecting rod 19 is also driven synchronously, so that the test probe 10 can rotate freely in multiple directions and a large angle range. As an important component of the transmission, the connecting rod 19 is responsible for transmitting the movement of the transmission ring 16 to the test probe 10, ensuring its flexibility and adaptability under various testing requirements. Through this series of movement effects, the test probe 10 can perform precise testing at different angles and directions, thereby providing extremely high flexibility and reliability, making the testing process more efficient and accurate. It can flexibly move and adjust the angle on the surface of the workpiece according to the specific shape of the workpiece, penetrate into various recesses, protrusions and bends, and comprehensively and accurately detect parameters such as voltage and current at different positions.

[0039] Working principle: When using the device, the workpiece to be inspected is stably clamped by the fixing seat 2, and the baffle 3 can effectively block the splashing objects so that they cannot reach the operator, thereby ensuring the personal safety of the operator near the detection area. When the test probe 10 is frequently moved to cover various parts of the weldment, due to the different shapes of the workpieces, the test probe 10 is prone to bending during the frequent movement. When it is subjected to external force, the spring 8 provided inside the connecting block 6 can absorb most of the force, effectively absorb and disperse these external forces, prevent the test probe 10 from breaking, and ensure that the test probe 10 remains intact during frequent position switching. The slide column 5 slides on the outer surface of the slide rail 4, thereby driving the test probe 10 to move horizontally. At the same time, the motor 13 drives the transmission column 14 to rotate, and then drives the fixed ball 21 to slide inside the slide groove 17. While sliding, it will drive the test probe 10 to move synchronously, so that the test probe 10 can rotate back and forth freely. While rotating, the transmission ring 16 can also be driven up and down by the output end of the electric push rod 15. While the transmission ring 16 moves up and down, the slide groove 17 opened inside the transmission ring 16 drives the fixed ball 21 to slide. Due to the curved shape of the fixed ball 21, it meets the conditions for following the up and down movement of the transmission ring 16, thereby further driving the connecting rod 19 to move synchronously, thereby further driving the test probe 10 to move synchronously, and can achieve free rotation in multiple directions and large angles. It is very flexible and can meet the testing requirements of the test probe 10 at different angles and directions.
