[0012] Beneficial effects

[0013] This utility model provides a welding workstation for automotive chassis. Compared with the prior art, it has the following advantages:

[0014] 1. This automotive chassis welding workstation first places the automotive chassis workpiece to be welded on the chassis welding fixture plate on the welding placement rack. Precise positioning and fixing of the workpiece is achieved through chassis positioning pins. The power source inside the welding fixture frame drives the chassis welding positioner's rotating shaft to rotate, thereby rotating the welding placement rack and the workpiece on it to the appropriate welding angle and position. Then, the welding robot body can meet the workpiece posture requirements of different welding processes. Employing two rotating positioning components allows the welding robot body to simultaneously perform pre-welding preparation or welding operations on two different automotive chassis workpieces. While a workpiece is being welded at one station, the other station can simultaneously perform workpiece loading / unloading, positioning, and other operations, thereby reducing equipment downtime and greatly improving production efficiency. Furthermore, the chassis welding fixture plate, through the mutual cooperation of the chassis positioning pins and the additional holes of the chassis positioning pins, is compatible with various workpiece models, thus improving fixture compatibility and suitability for positioning and welding more types of workpieces.

[0015] 2. This automotive chassis welding workstation, when welding automotive chassis, activates a motor based on the location of the welding point. The output shaft drives a threaded screw to rotate, which in turn moves the dust collection hood on the mounting plate, allowing for precise adjustment based on the welding point's location. This rapidly captures welding fumes, effectively improving dust collection at different welding points. The combination of an exhaust fan and a filtration system efficiently filters and purifies the inhaled fumes, expelling clean air and further improving the working environment, thus protecting the health of operators.

[0025] The smoke removal assembly 5 includes a housing 51, a threaded screw 52 is rotatably mounted on the inner wall of the housing 51, an mounting plate 54 is provided above the threaded screw 52, ​​and a dust suction hood 56 is provided above the mounting plate 54.

[0026] The welding fixture frame 41 is equipped with a power source to drive the base welding positioner tilting shaft 47 to rotate. The base welding fixture plate 44 is fixedly installed on the surface of the welding placement frame 42 by a set of base fixture plate positioning pins 43. The base fixture plate positioning pins 43 are used to position the base welding fixture plate 44.

[0027] The outer wall of the threaded screw 52 is threadedly connected to a movable slider 53. The movable slider 53 is movably inserted into the inner wall of the housing 51. The movable slider 53 is fixedly connected to the mounting plate 54. A bracket 55 is fixedly installed on the top of the mounting plate 54. When the threaded screw 52 rotates, it can drive the movable slider 53 to move on the inner wall of the housing 51, thereby driving the mounting plate 54 to move.

[0028] Figures 1-4The second embodiment is shown, and its main difference from the first embodiment is that: an exhaust fan 59 and a filter purification device 58 are fixedly installed on the top of the mounting plate 54 respectively. The output end of the exhaust fan 59 is fixedly connected to the filter purification device 58, and the output end of the filter purification device 58 is fixedly connected to a connecting pipe 57. The filter purification device 58 is existing technology and can purify and filter the smoke and dust before discharging it into the air. The exhaust fan 59 can generate negative pressure at the opening of the dust suction hood 56, so that the dust suction hood 56 can adsorb the smoke and dust above. The position of the dust suction hood 56 can be changed by the threaded screw 52, ​​so as to better treat the smoke and dust generated during the welding of the workpiece for different welding points.

[0029] The output end of the connecting pipe 57 passes through the inner wall of the bracket 55 and is fixedly connected to the dust hood 56.

The control box 3 can control multiple electrical components, thereby enabling better welding of the workpiece.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the car base workpiece to be welded is first placed on the base welding fixture plate 44 on the welding placement frame 42. The workpiece is precisely positioned and fixed using the base positioning pin 46. The power source inside the welding fixture frame 41 drives the base welding positioner's flipping shaft 47 to rotate, thereby flipping the welding placement frame 42 and the workpiece on it to a suitable welding angle and position. Then, the welding robot body 2 can meet the workpiece posture requirements of different welding processes. Using two flipping positioning components 4, the welding robot body 2 can simultaneously perform pre-welding preparation or welding operations on two different car base workpieces. While welding is being performed on one workstation, the other workstation can simultaneously perform workpiece loading / unloading, positioning, and other operations, thereby reducing equipment downtime and greatly improving production efficiency. Each base welding fixture plate 44, through the mutual cooperation of the base positioning pin 46 and the base positioning pin additional hole 45, can be compatible with various workpiece models, thereby improving the tooling compatibility and making it suitable for positioning and welding more types of workpieces. When welding the car base, the motor 510 is turned on according to the position of the welding point, and its output shaft drives the threaded screw 52 to rotate. During the rotation of the threaded screw 52, ​​the dust suction hood 56 on the mounting plate 54 can be moved to change position, so that the dust suction hood 56 can be precisely adjusted according to the position of the welding point, quickly capturing the fumes generated during welding, effectively improving the dust suction effect for different welding points. The combination of the exhaust fan 59 and the filter purification device 58 can efficiently filter and purify the inhaled fumes, expelling clean air, further improving the working environment and more effectively protecting the health of the operators.
