Problems solved by technology
The traditional commercially available pin-type clamping cylinder has a single model, complex mechanism, long delivery time, and high price. If special order is required, the cycle will be longer
When used for workpiece clamping, a single clamping head makes the state of workpiece clamping not stable enough

Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0020] Such as Figure 1-Figure 2 As shown, a three-jaw positioning and clamping mechanism for automobile body-in-white welding includes a workpiece positioning pin 1, a clamping mechanism and a driving mechanism 4, the driving mechanism 4 is connected with the clamping mechanism, and the clamping The mechanism is connected with the workpiece positioning pin 1.
[0021] The workpiece positioning pin 1 is a circular positioning pin, and there are multiple clamping mechanisms scattered around the workpiece positioning pin. The clamping mechanism includes a clamping arm 2 and a workpie...

The invention relates to a three-jaw positioning and clamping mechanism for welding an automotive body in white. The three-jaw positioning clamp mechanism comprises a workpiece positioning pin, a clamping mechanism and a driving mechanism, wherein the driving mechanism is connected with the clamping mechanism; the clamping mechanism is connected with the workpiece positioning pin; the driving mechanism drives the clamping mechanism to open, a workpiece is positioned through the end face of the workpiece positioning pin after the workpiece is put into the clamping mechanism, and the driving mechanism drives the clamping mechanism to start clamping. Compared with the prior art, the three-jaw positioning and clamping mechanism has the advantages of stable positioning and clamping, low cost, short processing time and the like.
Description
technical field [0001] The invention relates to a fixture for automobile welding, in particular to a three-jaw positioning and clamping mechanism for automobile body-in-white welding. Background technique [0002] Automobile industry equipment is a new industry that has recently emerged and developed rapidly. In fact, it also existed before this, but because the model changes of automobile manufacturers are not as frequent as they are now, and the types are so diverse, and the biggest change when changing models is the body-in-white. This requires that its corresponding welding line can keep up with the change of car models and types. In this case, the role of the welding line in automobile production and manufacturing is highlighted, making people pay more and more attention to it. On the automobile welding line, only 30% to 40% of the workload is actually used for welding operations, while 60% to 70% is the auxiliary and clamping work of the workpiece. Because the clamp...
