The process of sucking the gripping target member 200 by the riveting die set 20 is as follows: the riveting die set 20 moves to the upper end of the target member 200, and the stamping part 23 moves downward toward the target member 200 relative to the abutment member 22 under the effect of the riveting external force and protrudes out of the abutment member 22 to suck the target member 200 through the suction hole 233; after the target piece 200 is adsorbed, the stamping part 23 moves upwards relative to the abutting piece 22 under the effect of riveting external force and drives the target piece 200 to partially enter the abutting piece 22, and meanwhile, the guide surface 2216 automatically guides the position of the target piece 200, so that the target piece 200 is adsorbed, grabbed and precisely positioned.

Referring to fig. 7, an embodiment of the present application further provides a riveting method applied to the riveting device 100 in fig. 1 to 6, including the following steps:

s201, the stamping 23 is moved to take out the target 200.

S202, the stamping part 23 drives the target part 200 to move into the abutting part 22 under the action of the elastic part 24.

After the target 200 is moved, the stamping part 23 drives the target 200 to move into the abutment 22 under the action of the elastic member 24 and the compression member 25, at this time, a portion of the target 200 is located in the abutment 22, and in the process that the target 200 moves into the abutment 22, the guide surface 2216 of the end, far from the second receiving hole 2212, of the third receiving hole 2213 of the abutment 22 can center-locate the target 200, so as to adjust the position of the target 200.

S203, the abutting piece 22 is moved towards the product 300, so that the abutting piece 22 abuts against the slot 310 of the product 300.

Referring to fig. 8, the fixing base 21 and the abutment 22 move toward the product 300 under the driving action of the moving driving member 30, so that the limiting surface 220 of the abutment 22 abuts against the step of the first hole 311 and the second hole 312 of the product 300, there is no relative movement between the fixing base 21 and the movable member 28, and at this time, the upper surface of the movable portion 281 of the movable member 28 abuts against the upper groove wall of the movable groove 212, a gap exists between the lower surface of the movable portion 281 and the lower groove wall of the movable groove 212, the elastic member 24 and the compressing member 25 are in a loose state, and a portion of the target member 200 is located in the third receiving hole 2213 of the abutment 22.

S204, the pressing member 23 is moved toward the product 300 relative to the abutment member 22 and extends out of the abutment member 22 by a predetermined distance, so that the pressing member 23 presses the target member 200 into the slot 310 of the product 300 with a predetermined force.

Referring to fig. 9, the riveting cylinder (not shown) is made to push the stamping part 23 in the abutting part 22 to move towards the product 300 relative to the abutting part 22 and extend out of the abutting part 22 by a preset distance, so that the target part 200 and the product 300 are riveted, at this time, a gap exists between the upper surface of the movable part 281 and the upper groove wall of the movable groove 212, the lower surface of the movable part 281 is abutted to the lower groove wall of the movable groove 212, and the elastic part 24 and the compression part 25 are both in a compressed state.

The preset force is a riveting external force applied to the stamping part 23, and is smaller than the force for collapsing the product, which is required for collapsing and deforming the slot 310 of the product 300.

In the riveting method, the stamping part 23 after the target part 200 is moved into the abutting part 22 by the elastic part 24, the abutting part 22 is moved towards the product 300, so that the abutting part 22 abuts against the slot 310 of the product 300, and the stamping part 23 in the abutting part 22 is moved towards the product 300 and extends out of the abutting part 22 by a preset distance relative to the abutting part 22, so that the stamping part 23 presses the target part 200 into the slot 310 of the product 300 with a preset force, and the problem that the step difference between the target part 200 and the product 300 after the target part 200 is riveted is large due to the processing error and the movement error of the product 300 and the target part 200 during processing can be avoided by controlling the preset distance.

The riveting device 100 and the riveting method can simultaneously finish adsorption, grabbing, fine positioning, riveting and control the section difference specification aiming at the structure of the target piece 200; the target piece 200 is sucked up through the two adsorption holes 233 on the stamping part 23, and is automatically positioned in a centering way through the guide surface 2216 at one end of the third accommodating hole 2213 far away from the second accommodating hole 2212, so that the positioning precision is high, the structure is simple, and the processing is easy.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
