Sleeve rotating welding device of sensor pins

Abstract

The invention discloses a sleeve rotating welding device of sensor pins. A tool clamp comprises a positioning head which is arranged in the axial direction of a rotating shaft, and clamping heads forallowing the a workpiece to realize clamping are arranged on the two sides of a positioning head; laser rays emitted by a laser welding head on one side of the tool clamp is focused on a product revolution surfaces outside the clamping heads; an annular light source is arranged outside the laser welding head in a sleeved mode, the laser welding head is installed on a supporting assembly capable ofbeing adjusted in a displacement mode; the side face of the tool clamp is further provided with a limiting plate capable of being inserted into the positioning head and realizing that a workpiece isaligned and positioned through the end part of a clamping end, and the limiting plate is driven by a displacement assembly to achieve linear movement of the limiting plate along the axial direction orthe radial direction of the workpiece; and a plurality of sensing heads used for detecting the clamping states of the workpiece are further arranged on the side face of the tool clamp, the laser welding head comprises a visual camera, a laser generating unit and an annular light source which are arranged on the same optical axis, wherein the visual camera is used for carrying out position precision detection on the focusing point and the welding point of the laser wire harness passing through the annular light source.

Description

technical field [0001] The invention relates to the field of welding equipment for sensor pins, in particular to a sleeve rotation welding equipment for sensor pins. Background technique [0002] With the rapid development of automobile technology and electronic technology, electronic technology and computer technology have been widely used in automobiles. The driving system, steering system, braking system and body generally use electronic control devices. The car has become a mechatronics product. In the automotive electronic control system, the sensor is responsible for the collection and transmission of information. It is a very important component in the electronic control system, and converts them into electrical signals that the computer can accept and sends them to the ECU. The ECU performs calculations based on this information. processing, and then issue instructions. [0003] Sensors are used more and more as important electronic components. In particular, the...

Problems solved by technology

However, it is difficult to match various types of sensor leads because it is difficult to ensure accurate positioning of the product during the clamping process, or the unstable clamping force may cause damage to the workpiece.

Moreover, such tooling is troublesome to replace, and there is a risk of damage to the tooling fixture or the risk of injuring the staff, which will occupy a large working space
