Description

Technical Field

[0001] The utility model relates to the technical field of automobile processing, in particular to a thin plate anti-leakage detection device. Background Art

[0002] The front suspension of a car is a general term for the force-transmitting connection device between the car frame and the axle or wheel. A typical front suspension system is composed of elastic elements, guide mechanisms, shock absorbers, etc. The parts that make up the front suspension are not only diverse but also have their own uses and are indispensable.

[0003] According to the comparison of existing technologies, in order to enhance the mechanical strength of local areas on some sheet metal parts, it is often necessary to weld a reinforcing plate in the area to enhance the mechanical strength of the area. Regardless of whether spot welding, arc welding or laser welding is used, parts are often missed during the processing due to manual operation. Traditional sensors cannot detect whether there is a missing part due to their sensing accuracy or their shape cannot be leak-proof, resulting in defective products flowing to the client and causing huge losses. Utility Model Content

[0004] The utility model aims to provide a thin plate anti-leakage detection device which can play the role of anti-leakage function.

[0005] In order to achieve the above-mentioned purpose, a thin plate anti-leakage detection device is provided, including a reinforcing plate, a side plate is arranged at the lower end of the reinforcing plate, a clamping head is arranged at the side of the side plate, a push rod is arranged at the side of the clamping head, a pointer is arranged at the lower end of the push rod, a mounting seat is arranged at the side of the pointer, a sensor is arranged inside the mounting seat, a fulcrum is arranged on the side of the mounting seat, a return spring is arranged inside the pointer, an annular groove is opened inside the mounting seat, a fixed base is arranged at the lower end of the side plate, a floating spring is fixedly connected to the upper end of the fixed base, a linear bearing is arranged at the upper end of the floating spring, and a cylindrical A guide column, wherein a transition electrode seat is arranged at the upper end of the cylindrical guide column, a transition electrode is fixedly connected to the upper end of the transition electrode seat, a welding clamp lower electrode is arranged at the lower end of the transition electrode seat, a welding clamp lower bent nozzle is arranged at the lower end of the welding clamp lower electrode, a part b is arranged at the upper end of the part b, a welding clamp upper electrode is arranged at the upper end of the part b, a welding clamp upper electrode is arranged at the upper end of the welding clamp upper electrode rod, a part a is arranged at the lower end of the welding clamp upper electrode rod, a part c is arranged at the lower end of the part a, a bakelite bottom plate is arranged at the upper end of the floating spring, an electrode fixing seat is arranged on the side of the linear bearing, and a contoured transition electrode is arranged at the upper end of the electrode fixing seat.

[0006] According to the thin plate anti-leakage detection device, the reinforcing sheet is clamped by a clamping head and a push rod fixed on the clamping head. Under the action of the push rod, the downward pressure pointer rotates along the fulcrum. When the clamping head is clamped in place, the push rod presses the pointer down and rotates to a specified position along the fulcrum. The other end of the pointer will rotate to the position of the sensor, which is just sensed by the sensor and sends out a sensing signal to perform normal welding work.

[0007] According to the thin plate leakage prevention detection device, the parts a and c can be spot welded directly with welding tongs. When welding parts a and b, the welding tongs act on the transition electrode. During welding, the upper electrode of the welding tongs is pressed down to press parts a, part b and the transition electrode. The welding current passes through the upper electrode of the welding tongs, part a, part b, the transition electrode, and finally returns to the lower electrode of the welding tongs to form a welding circuit, forming a molten core between parts a and b to achieve the purpose of welding.

[0008] According to the thin plate leak detection device, the contoured transition electrode, that is, the upper end face of the transition electrode conforms to the part and the lower end face is parallel to the part a, which solves the welding problem of non-parallel upper and lower planes of spot welding.

[0009] The utility model has the following beneficial effects:

[0010] 1. Compared with the prior art, this thin plate leak detection device loosens the pressing head and drives the push rod to loosen. Under the action of the reset spring, the pointer returns to the original position. When the reinforcing sheet and the side plate are installed in place, the pressing head drives the push rod to press the pointer down. The distance between the fulcrum on the pointer and the push rod is 15mm, and the distance between the sensor and the fulcrum is 150mm. The ratio of the distance between the left and right ends is exactly 1:10, that is, the left push rod presses down the pointer and displaces 1mm, and the left side of the pointer moves upward by nearly 10mm. When the reinforcing sheet is correctly installed in place, The left end of the pointer just points to the position of the sensor, and the annular groove can freely adjust the position of the sensor. When the reinforcement sheet is not installed, the clamping head will drive the push rod to excessively press down the pointer, and the pointer will rotate along the fulcrum. The left end of the pointer will exceed the position of the sensor. Because the thickness of the reinforcement sheet is 1.5mm, the push rod will excessively press down the pointer and move down 1.5mm. The left end of the pointer will move up about 15mm, which plays a role in gap amplification. In this way, the sensor cannot detect the pointer, and there is no signal output, and the equipment will not run, which plays a role in leak prevention.

[0011] 2. Compared with the prior art, this thin plate leak detection device realizes the welding process due to the non-parallel upper and lower welding surfaces by having the robot welding clamp directly act on the lower end face of the contoured transition electrode during the welding process and the upper electrode of the welding clamp presses the part a for welding.
