Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the embodiment provides a part material thickness self-adaptive pressing device, which comprises a cylinder 01 and a self-adaptive pressing head 04 connected to the output end of the cylinder 01;

the adaptive ram 04 comprises a hollow sleeve 09 and a spring 08 embedded in the sleeve, the bottom of the spring 08 is connected with a guide rod 10, and the tail end of the guide rod 10 is connected with a movable ram 11.

The specific connection is shown with reference to figures 1 and 3, the output end of the air cylinder 01 is fixedly connected with the pressing arm 03, and the self-adaptive pressure head 04 is connected to the pressing arm 03; the top end of the sleeve of the self-adaptive pressure head 04 is provided with an upper bolt groove 07, and the upper bolt groove 07 is used for fixedly connecting with the pressure arm 03 by adopting a bolt structure.

The bottom of the movable pressure head 11 is provided with a lower bolt groove 12, and the lower bolt groove 12 is used for connecting and fixing the pressure head by adopting a bolt structure. For further convenience, the movable press head 11 may be hinged to the guide rod 10, and has a small range of rotational degrees of freedom (for example, 30 ° or less than 30 °), and the end of the movable press head 11 is connected to a fixed press head, so that the press head can be assisted to simultaneously adapt to the surface and thickness of the workpiece under the action of the spring and the rotational degrees of freedom.

Still including pressing the arm limit structure, press the bottom of arm limit structure installation at pressing the arm, including angle seat 06, fixed mounting template 05 and fixed mounting at the stopper 02 of pressing the arm bottom surface on angle seat 06, the spacing groove with stopper 02 adaptation has been seted up to the tip of template 05, in order to optimize spatial layout, reference figure 4 shows that cylinder 01 and angle seat 06 all install perpendicularly. The cylinder outsources Adand cylinder, and other parts except the spring can be processed by adopting Q235 materials.

Referring to fig. 4, in use, the first workpiece is assembled with the second workpiece in a fixture, and the fixture is welded. And after the welding is finished, opening the pressing arm to assemble a workpiece III, and clamping the pressing arm.
