[0038] Please refer to Figures 1-5 , a flexible positioning carrier device for a riveting system in this embodiment, which is used to position a workpiece 100. The flexible positioning carrier device for the riveting system includes:

[0039] A wire mesh plate mechanism 1;

[0040] An adjusting mechanism 2, the adjusting mechanism 2 includes a base 21, a lead screw 22, a guide rail 23, a lead screw nut slider 24, a cross beam 25, a front end base plate 26, and a rear end base plate 27. Among them, the guide rail 23 is fixed on the base 21, the lead screw 22 passes through the base 21 and the lead screw nut slider 24, the lead screw nut slider 24 is slidably installed in the guide rail 23, the lead screw nut slider 24 is connected to the cross beam 25, the front end base plate 26 is fixed on one side of the cross beam 25, the rear end base plate 27 is fixed on one side of the base 21, and the front end base plate 26 faces the rear end base plate 27, so that the rotation of the lead screw 22 can make the lead screw nut slider 24 drive the cross beam 25 and the front end base plate 26 to move reciprocally in the direction relative to the rear end base plate 27;

[0041] The positioning mechanism 3 includes a plurality of first positioning members 31 and a plurality of second positioning members 32. Any one of the plurality of first positioning members 31 is slidably mounted on the cross beam 25 or the base 21, and any one of the plurality of second positioning members 32 is slidably mounted on the cross beam 25 or the base 21. The first positioning member 31 is used to limit the edge of the workpiece 100 along the extension direction of the cross beam 25 and the base 21, and the second positioning member 32 is used to limit the edge of the workpiece 100 along the direction perpendicular to the extension direction of the cross beam 25 and the base 21;

[0042] The wire mesh plate mechanism 1 is arranged through the front end bottom plate 26 and the rear end bottom plate 27. The front end bottom plate 26, the rear end bottom plate 27, and the wire mesh plate mechanism 1 are used to support the workpiece 100; A pressing mechanism 4 is further included. The pressing mechanism 4 includes a rotary cylinder 41, a rotating shaft 42, and a plurality of pressing claws 43. The output end of the rotary cylinder 41 is connected to the rotating shaft 42, and the plurality of pressing claws 43 are fixed on the rotating shaft 42. The rotary cylinder 41 is used to drive the pressing claws 43 to rotate and press down through the rotating shaft 42, so that the workpiece 100 is pressed on the front end bottom plate 26, the rear end bottom plate 27, and / or the wire mesh plate mechanism 1.

[0043] With the above structure, during use, the operator only needs to first obtain the size of the workpiece 100 to be processed, and then based on the above size, rotate the lead screw 22 of the rotation adjustment mechanism 2, so that the rotation of the lead screw 22 drives the lead screw nut slider 24 to displace relative to the guide rail 23. Specifically, the rotation method can be a motor. In this embodiment, it is selected as Figure 2The handwheel 28 shown. After the nut slider 24 drives the connected crossbeam 25 and the front end base plate 26 on one side to move to the preset position and stop, at this time, the distance between the front end base plate 26 and the rear end base plate 27 matches the width dimension of the workpiece 100. After placing the workpiece 100 on the front end base plate 26, the rear end base plate 27, and the wire mesh plate mechanism 1, the position of the workpiece 100 is further fixed by means of the positioning mechanism 3. Specifically, the first positioning member 31 is installed on the base 21 or the crossbeam 25 and moved towards the workpiece 100, so that the workpiece 100 is tightened by a plurality of first positioning members 31, and the workpiece 100 is limited in the extending direction of the base 21 and the crossbeam 25 by a plurality of first positioning members 31. Then, similarly, the second positioning member 32 is installed on the base 21 or the crossbeam 25 and moved towards the workpiece 100, so that the workpiece 100 is tightened by a plurality of second positioning members 32, and the workpiece 100 is limited in the direction perpendicular to the extending direction of the base 21 and the crossbeam 25 by a plurality of second positioning members 32. At this time, the workpiece 100 is limited from two directions, realizing precise positioning of the plane angle. Then, adjust the positions of the plurality of claws 43 of the pressing mechanism 4 so that they are close to the corner positions of the workpiece 100, and start the rotary cylinder 41 to drive the rotating shaft 42 to drive the claws 43 to rotate towards the upper surface direction of the workpiece 100 and press down on the upper surface of the workpiece 100, so that the workpiece 100 is pressed on the wire mesh plate mechanism 1, forming a stable fixation of the vertical angle. At this time, the workpiece 100 has completed the positioning in the horizontal and vertical two levels, and the subsequent riveting operation can be started.

[0044] In the above usage process, the rough adjustment of the position of the stage for carrying the workpiece 100 is realized by means of the adjusting mechanism 2, and the specific horizontal positioning of the workpiece 100 is realized by means of a plurality of first positioning members 31 and second positioning members 32 in the positioning mechanism 3. Therefore, in the embodiment of the present invention, the horizontal dimension of the workpiece 100 is flexibly and adaptively adjusted, significantly increasing the usage dimension range, realizing the positioning of workpieces 100 with multiple dimensions with a single set of stage devices, and indirectly reducing the cost. Finally, the workpiece 100 is stably pressed on the wire mesh plate mechanism 1 by means of the pressing mechanism 4, and the stability of the vertical positioning of the workpiece 100 is enhanced by means of the variable pre-tightening force of the wire mesh plate mechanism 1 itself.

[0045] Further, as Figure 2 shown, the end of the lead screw 22 is connected with a handwheel 28, and the handwheel 28 is used to drive the lead screw 22 to rotate relative to the base 21 and the lead screw nut slider 24. The handwheel 28 has a low usage cost, can be manually operated with a meter stick, and still realizes a high positioning accuracy.

[0046] Further, please refer to Figure 1 、 2, 5. The adjustment mechanism 2 also includes another set of symmetrically arranged screws 22, guide rails 23, and screw nut sliders 24. The combination of two screws 22, guide rails 23, and screw nut sliders 24 is connected by a pair of pulleys installed on each screw 22 and a belt 29 between the pair of pulleys, so that the pair of screws 22 and the pair of screw nut sliders 24 can move synchronously; wherein the crossbeam 25 is fixed between the pair of screw nut sliders 24. With the help of the above structure, in fact, a rectangular bearing frame is enclosed in this embodiment, and a pair of guide rails 23 constitute the left and right sides, and the crossbeam 25 and the base 21 constitute the upper and lower sides. On this basis, when positioning the workpiece 100, the workpiece can be placed in one of the corners of the rectangular frame. Specifically, the positioning mechanism in this embodiment also includes a plurality of third positioning members 33, and the plurality of third positioning members 33 can be slidably installed on one of the guide rails 23. The third positioning member 33 is used to limit the edge of the workpiece 100 along the extension direction of the crossbeam 25 and the base 21. The third positioning member 33 and the first positioning member 31 are arranged relative to each other. As Figure 1 In the embodiment shown, the workpiece 100 is placed at the lower right corner of the rectangular frame. Therefore, it is only necessary to adjust the position of the crossbeam 25 to achieve positioning of the workpiece 100 from four sides by means of the joint abutment of the first positioning member 31, the second positioning member 32, and the third positioning member 33.

[0047] Specifically, the workpiece 100 is set to be a rectangle, and the clamping mechanism 4 has a pair of oppositely arranged ones, and each corner of the rectangle is provided with a first positioning member 31, a second positioning member 32, a third positioning member 33 and a pressing claw 43. That is to say, in this embodiment, a total of four pairs of first positioning members 31, second positioning members 32, third positioning members 33 and pressing claws 43 are provided and respectively placed at the four corners of the rectangle to achieve stable and balanced positioning of the rectangle.

[0048] Of course, in some other embodiments, different numbers of groups of first positioning members 31, second positioning members 32, third positioning members 33 and pressure claws 43 may be provided according to different stability requirements. As long as fixed stability requirements are met, the technical concept of this embodiment is not deviated.

[0049] Furthermore, if Figure 3As shown in the figure, the wire mesh plate mechanism 1 includes two sliding grooves 11, a plurality of wire fixing blocks 12, and a plurality of wires 13. The two sliding grooves 11 are arranged oppositely. Each end of each wire 13 is respectively connected with a wire fixing block 12, and each wire fixing block 12 is installed in the sliding groove 11 at the corresponding position. Before placing the workpiece 100, the tensile strength of the wire 13 can be adjusted through the corresponding two wire fixing blocks 12 according to the bearing strength requirement of the workpiece 100, so as to realize different supporting forces of the wire 13. Further, grooves for accommodating the wire 13 are provided on the top surfaces of the front end bottom plate 26 and the rear end bottom plate 27. The position of the wire 13 can be adjusted by adjusting the position of the wire fixing block 12 in the sliding groove 11, and the wire 13 is arranged to pass through the corresponding groove, so as to avoid interference friction between the wire 13 and the front end bottom plate 26 and the rear end bottom plate 27, which affects the service life of the structure. During the positioning process, the clamping jaws 43 of the clamping mechanism 4 press the bottom surface of the workpiece 100 against the wire 13, the front end bottom plate 26 and the rear end bottom plate 27. Among them, the wire 13 plays an elastic supporting role to realize uniform and stable supporting protection. The wire 13 in the groove also has a certain elastic movement space, and the front end bottom plate 26 and the rear end bottom plate 27 limit the position depth where the workpiece 100 is specifically pressed.

[0050] Further, please refer to Figure 2 , a front end meter 261 is installed on one side of the front end bottom plate 26, a rear end meter 271 is installed on one side of the rear end bottom plate 27, and a guide rail meter 231 is installed on one side of the guide rail 23. By ending the meters installed near the positioning of the workpiece 100, the operator can timely fine-tune the positioning accuracy of the workpiece 100 to avoid positioning deviation.

Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present invention are included in the scope of the patent application of the present invention.
