Description

Technical Field

[0001] This utility model relates to the welding fixture for the stamping sheet and flange of the exhaust temperature sensor, and belongs to the technical field of exhaust temperature sensor production equipment. Background Technology

[0002] The automotive exhaust temperature sensor used to detect the exhaust temperature of a car engine consists of components such as armored cable, flange, stamped plate, and chip. The stamped plate and flange need to be laser welded, and during welding, it should be ensured that the protrusion on the stamped plate and the pin are in a straight line.

[0003] In the existing technology, the positioning fixtures used for welding stamped sheets and flanges are generally simple. The positional relationship between the stamped sheet protrusion and the pin is manually controlled, which often results in positional misalignment and affects the welding quality. Utility Model Content

[0004] This utility model proposes a welding fixture for the stamping sheet and flange of a temperature exhaust sensor, which aims to overcome the above-mentioned shortcomings of the existing technology, ensure welding accuracy, and improve product quality.

[0005] The technical solution of this utility model is a welding fixture for a temperature sensor stamped sheet and a flange. Its structure includes a rotating drive mechanism and a tail-top mechanism mounted on a mounting plate. The rotating drive mechanism includes a mounting bracket, with a drive motor reducer mounted on the back of the bracket. The output end of the drive motor reducer is connected to a rotating insert plate on a rotating seat on the front of the mounting bracket. A insert tube is located at the center of the rotating insert plate. A pin positioning slot is located at the inner end of the insert tube, and a pair of positioning pin holes are located at the outer end of the insert tube. Positioning pins are inserted into the positioning pin holes. The projections of the two positioning pin holes and the pin positioning slot on the horizontal plane are parallel to each other, and the pin positioning slot is located at the center of the two positioning pin holes. A flange body, fitted with the stamped sheet, is inserted into the insert tube, and a pair of pins at the end of the flange body are inserted into the pin positioning slot. A protrusion on the stamped sheet body is limited between the pair of positioning pins. One end of the flange body, fitted with the stamped sheet, is inserted into the rotating drive mechanism, and the other end is supported by the tail-top mechanism. The rotating drive mechanism drives the flange body to rotate, and laser welding is performed by an external three-axis welding mechanism. The specific design of the positioning pin hole and pin positioning slot ensures that the protrusion of the stamping sheet body and the pin are in a straight line. The drive motor reducer drives the workpiece to rotate, which is to perform laser welding. After the welding is completed, the reverse action is performed to remove the workpiece.

[0006] Preferably, the tail-top mechanism includes a cylinder and a guide rail mounted on a cylinder frame. The cylinder output end is connected to a sliding frame slidably connected to the guide rail. A mounting base is mounted on the sliding frame, and a tail-top block is fixed on the mounting base. The tail-top block is positioned opposite to the insert tube. The cylinder pushes the tail-top block to press against the tail of the workpiece, thereby driving the motor reducer to rotate the workpiece for laser welding.

[0007] The advantages of this utility model are: reasonable structural design, which can accurately position the direction and position of the stamping plate protrusion and the pin through tooling, ensuring the accuracy of laser welding and effectively improving product quality.
