Further illustrate, described the second drive unit is electric drive axle; On described electric drive axle, be provided with motion platform; Described supporting plate is fixed on described motion platform.
Further illustrate, described pressing plate is transparency silica glass plate; Described supporting plate is U-shaped structure and agrees with mutually with the bottom of plastics.
The beneficial effect that the utility model embodiment brings is: on supporting plate, be provided with elastic parts, uniform pressure can be provided, form good support, plastic products levels can be fitted tightly, ensure the quality of welding.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model embodiment fixed plastics.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of plastics fixture for laser welding, and uniform pressure can be provided, and ensures fitting tightly of plastic products levels.
Fig. 1 is the schematic diagram of the utility model embodiment fixed plastics.
As shown in Figure 1, plastics fixture for laser welding comprises the pressing plate 1 and the supporting plate 2 that are oppositely arranged up and down, and is arranged at the elastic parts on supporting plate 2.The position of elastic parts is corresponding with the position of plastic welded seam.Particularly, elastic parts can be some tracheaes, can be also several Compress Springs.
In the present embodiment, elastic parts is a pair of tracheae 3, and material is high resilience polyurethane flexible pipe, and the first from left right side is laid on supporting plate 2 respectively, and the position of tracheae 3 and the position of plastic welded seam corresponding.One end of tracheae 3 is connected with air pressure regulator (not shown) and feeder (not shown).Before plastics clamping, need first tracheae 3 emptying, connect feeder after clamping, what source of the gas was selected conventionally is compressed air.Tracheae 3 upwards supports plastics underclad portion under the effect of gas pressure, and plastic top part is spacing by pressing plate 1, jointly completes fitting tightly of plastics levels.Because tracheae 3 is flexible, therefore can ensure that each position of whole piece weld seam can both contact well.In the present embodiment, when welding, the pressure of tracheae 3 is 0.5MPa.Certainly,, for soft or hard degree, the structure of different plastic products and the pressure that can bear, can pass through the best air pressure of air pressure regulator flexible modulation tracheae 3.
In the present embodiment, pressing plate 1 is connected with the first drive unit (not shown), drives lower platen 1 to be in vertical motion at it.Particularly, the first drive unit comprises servomotor and screw mandrel; Servomotor is positioned at the top of pressing plate 1, and pressing plate is fixedly connected with servomotor by screw mandrel.Servomotor also can substitute with cylinder.
