M4 Automotive underbody sub-assembly welding work island

Case highlights: 1. Renovation of existing fixtures with low cost and short cycle; 2. There are many types of flexible switching of fixtures, automatic switching of various welding tongs, 4 robots and one master control station, 27 sets of fixtures, and 16 stations.

Analysis on the structure and working principle of the transmission device of the automobile welding production line

Taking the transmission device of the automobile side panel assembly as an example, its structure and working principle will be analyzed in detail below.

The transmission device of the side panel assembly line of a certain vehicle type adopts a four-station reciprocating rod device, which can realize horizontal and vertical movement. The structure and function analysis of each sub-assembly is as follows:

horizontal moving device

The working principle of this part has been mentioned above, simply put, the rack and pinion device in the drive unit drives the moving slide to drive the workpiece to move horizontally. It is worth mentioning that the positioning block installed on the mobile skateboard mainly plays the role of positioning the workpiece, and the form of the positioning block for the side wall of different models is also different. If you want to weld the side wall of other models, you only need to replace the positioning block. Other parts do not need to be greatly modified. Compared with the traditional transmission device, this method has been further developed towards flexibility.

The base board structure of each station

The base plates of each station are connected together through connecting plates to form the supporting device of the entire automobile welding line, which must support both the entire transmission device and the welding fixture. In addition, in order to ensure that the datum of the fixture and the body parts are consistent, draw the datum scale line on the base board according to the design datum. The leveling device in the figure mainly plays a role in leveling the entire transmission device.

What has been introduced above is the main structure of the transmission device, and there are some auxiliary devices in addition to this.
