Problems solved by technology

Therefore, how to control the precise opening of the throttle valve plate has become a research hotspot. There are two main ways to connect the sector gear and the valve plate ejector rod in the market: 1. The valve plate ejector rod is directly stuck in the center hole of the sector gear; 2. Electroplating welding is used to weld the contact edge of the sector gear and the valve plate ejector rod, but there are various problems in these two methods: First, it is difficult to precisely control the throttle valve plate by directly clamping the valve plate ejector rod to the center hole of the sector gear The opening angle of the valve plate may cause the throttle valve plate to not respond at all when the sector gear rotates after long-term use; second, use electroplating welding to weld the contact edge of the sector gear and the valve plate ejector pin to intelligently maintain the sector gear and the valve for a short time The connection of the plate ejector rod still cannot control the opening angle of the throttle valve plate

specific Embodiment example 2

[0026] The invention proposes a laser welding method for a sector gear and a valve plate ejector rod in an electronic damper, which includes: positioning the ejector pin at the bottom of the valve plate ejector rod, closing the valve plate ejector rod, adjusting the sector gear, starting laser welding, turning off the laser, The rotating sector gear detects the opening angle of the throttle valve plate, and the CCD detects the weld seam. Rotate the sector gear to the WUMA flow angle of 13.5°, the throttle valve plate is opened by 13.5°, and the encoder at the bottom of the ejector pin positioning mechanism at the bottom of the valve plate feeds back the values ​​of each angle and the opening angle value of the servo motor for comparison and verification.

[0028] The invention proposes a laser welding method for a sector gear and a valve plate ejector rod in an electronic damper, which includes: positioning the ejector pin at the bottom of the valve plate ejector rod, closing the valve plate ejector rod, adjusting the sector gear, starting laser welding, turning off the laser, The rotating sector gear detects the opening angle of the throttle valve plate, and the CCD detects the weld seam. Rotate the sector gear to fully open, the throttle valve plate is fully opened, and the encoder at the bottom of the ejector pin positioning mechanism at the bottom of the valve plate feeds back the values ​​of each angle and the opening angle value of the servo motor for comparison and verification.

Abstract

The invention discloses a laser welding method for a sector gear and a valve block ejecting rod in an electronic air throttle. The laser welding method for the sector gear and the valve block ejectingrod in the electronic air throttle includes positioning of a bottom ejecting pin of the valve block ejecting rod, closing of the valve block ejecting rod, sector tooth adjusting, laser device weldingstarting, closing of a laser device, detection of an opening angle of a valve plate of the air throttle by means of rotation of the sector gear, and CCD weld joint detection. By means of the laser welding method, the contact edge of the sector gear and the valve block ejecting rod can be steadily welded, and it is guaranteed that the rotating angle of the sector gear and the opening angle of thevalve plate of the air valve are completely consistent. The problem that welding of the plastic sector gear and the metal valve block ejecting rod is not firm and even welding cannot be performed is solved, and meanwhile it is guaranteed that a torque value of the opening angle of sector teeth and the opening angle of the valve plate are consistent.

Description

technical field [0001] The invention belongs to the field of mechanical automation, and in particular relates to a laser welding method for a sector gear and a valve plate ejector rod in an electronic damper. Background technique [0002] The electronic throttle valve is the control system for the engine in the car. The electronic throttle valve is used to control the opening angle of the throttle valve plate to improve the fuel economy of the vehicle; at the same time, the stability, power and safety of the vehicle are improved. Therefore, how to control the precise opening of the throttle valve plate has become a research hotspot. There are two main ways to connect the sector gear and the valve plate ejector rod in the market: 1. The valve plate ejector rod is directly stuck in the center hole of the sector gear; 2. Electroplating welding is used to weld the contact edge of the sector gear and the valve plate ejector rod, but there are various problems in these two method...
