Description

Technical Field

[0001] The utility model belongs to the technical field of automobile standard parts welding detection, in particular to an automobile standard parts welding leakage and error prevention tooling. Background Art

[0002] The leak-proof and error-proofing of standard parts originated in Europe and was applied to the automotive industry. Foreign research started earlier and became more mature. The complexity of the technology and its huge application potential have attracted the attention of countries around the world. In recent years, some domestic automobile OEMs have conducted research on leak-proof and error-proofing technology. Compared with foreign countries, domestic research on this technology started later. Foreign technology is now more mature and has implemented a technical blockade.

[0003] The leak-proof and error-proofing tooling for standard parts is a technical extension of the leak-proof and error-proofing technology. The leak-proof and error-proofing tooling has a strong standard part recognition capability, which can reduce the error rate of product parts, thereby improving product quality, reducing customer complaints, making the product more competitive in the market, and using this as the core competitiveness to achieve market share.

[0004] At present, my country's automobile standard parts leakage and error prevention technology has achieved certain results, and some independently developed automobile standard parts leakage and error prevention tooling have emerged. However, in the assembly and welding process of automobile parts, my country's automobile standard parts leakage and error prevention tooling still has problems such as complex design, high cost, and difficult maintenance. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a leakage and error-proof tooling for welding automobile standard parts which has a simple structure, low cost and low maintenance cost.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows: a leak-proof and error-proof tooling for welding automobile standard parts, such as Figure 1 As shown, it includes a cabinet, an equipment base plate, a detection column, a hand switch, a buzzer light, a fixing rod, and a PLC system.

[0007] The detection column is fixedly installed on the bottom plate of the equipment according to the position of the projection-welded square nut on the part to be detected. The number of the detection column is the same as the number of the projection-welded square nut. The detection column includes a support body, a sensor combination A, and a sensor B. The shape of the support body is made according to the needs, such as Figure 2 , Figure 3As shown, the bottom end of the support body has a screw hole for fixing the detection column on the bottom plate of the equipment. The top end of the support body is a plane, and there are two circular holes on the plane that vertically pass through the support body, namely circular hole A and circular hole B. A sensor assembly A is installed in circular hole B, and circular hole B is directly opposite to the convex welded square nut on the part to be detected. The top end of the sensor assembly A is a disc with the same diameter as circular hole B. The upper surface of the disc is lower than the top plane of the support body. A spring is fixedly connected to the lower bottom surface of the disc. The other end of the spring is fixedly connected to sensor A. Sensor A is fixedly connected in circular hole B. The lower end of sensor A is electrically connected to the PLC system through a wire. The PLC system is located in the cabinet and is electrically connected to the power supply. Sensor B is fixedly installed in circular hole A. The top of sensor B is lower than the top plane of the support body, and the lower end of sensor B is electrically connected to the PLC system through a wire. Sensor B is used to detect whether the parts to be inspected are placed incorrectly. If all sensors B do not detect a signal, the PLC system determines that no parts to be inspected are placed, and the PLC system controls the buzzer to not light up or make a buzzer sound. If a sensor B detects a signal and the remaining sensors B cannot detect a signal at the same time, the PLC system determines that the operator has placed the parts to be inspected incorrectly, and the PLC system controls the buzzer to emit blue light and make a buzzer sound. If all sensors B detect a signal, the PLC system determines that the operator has not placed them incorrectly, and the PLC system controls the buzzer to not light up or make a buzzer sound.

[0008] A fixing rod is also fixedly installed on the bottom plate of the equipment. The fixing rod is a vertical thin rod device. The fixing rod is located at the edge of the component to be detected and is used to assist in fixing the component to be detected. The fixing rod isolates the component to be detected from the buzzer light.

[0009] A buzzer light is fixedly installed on the bottom plate of the equipment at a position away from the parts to be inspected.

[0010] A hand switch is fixedly installed on the bottom plate of the equipment near the operator. The hand switch is electrically connected to the PLC system through a wire. After the parts to be tested are correctly placed, the operator presses the hand switch to start testing. When all sensors A detect the convex welded square nuts, the parts to be tested are qualified, and the PLC system controls the buzzer to emit a green light without making a sound. When at least one of the sensors A cannot detect the convex welded square nut, it means there is a weld leak, and the parts to be tested are unqualified, and the PLC system controls the buzzer to emit a red light and a buzzer sound at the same time.

[0011] Through the above-mentioned design scheme, the utility model can bring the following beneficial effects: it can detect whether the parts to be inspected are placed incorrectly, effectively detect whether the parts to be inspected are leaking, effectively reduce sensor loss, increase the versatility of tooling, and effectively reduce production costs and maintenance costs.
