[0038] Please see Figure 1-5 This embodiment provides a flexible positioning platform device for a riveting system, used for positioning workpiece 100. The flexible positioning platform device for the riveting system includes:

[0039] Wire mesh plate mechanism 1;

[0040] Adjustment mechanism 2 includes a base 21, a lead screw 22, a guide rail 23, a lead screw nut slider 24, a crossbeam 25, a front base plate 26, and a rear base plate 27. 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 and is connected to the crossbeam 25. The front base plate 26 is fixed on one side of the crossbeam 25, and the rear base plate 27 is fixed on one side of the base 21. The front base plate 26 faces the rear base plate 27 so that the rotation of the lead screw 22 can cause the lead screw nut slider 24 to drive the crossbeam 25 and the front base plate 26 to reciprocate relative to the rear base plate 27.

[0041] The positioning mechanism 3 includes a plurality of first positioning elements 31 and a plurality of second positioning elements 32. Any one of the plurality of first positioning elements 31 is slidably mounted on the crossbeam 25 or the base 21, and any one of the plurality of second positioning elements 32 is slidably mounted on the crossbeam 25 or the base 21. The first positioning elements 31 are used to limit the edge of the workpiece 100 along the extending direction of the crossbeam 25 and the base 21, and the second positioning elements 32 are used to limit the edge of the workpiece 100 along the extending direction perpendicular to the extending direction of the crossbeam 25 and the base 21.

[0042] The wire mesh plate mechanism 1 is provided with a front base plate 26 and a rear base plate 27. The front base plate 26, the rear base plate 27, and the wire mesh plate mechanism 1 are used to support the workpiece 100. It also includes a pressing mechanism 4, which includes a rotary cylinder 41, a rotating shaft 42, and multiple pressing claws 43. The output end of the rotary cylinder 41 is connected to the rotating shaft 42, and the multiple 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 base plate 26, the rear base plate 27, and / or the wire mesh plate mechanism 1.

[0043] With the above structure, during use, the operator only needs to obtain the dimensions of the workpiece 100 to be processed, and then, based on the above dimensions, rotate the lead screw 22 of the adjusting mechanism 2, so that the rotation of the lead screw 22 drives the lead screw nut slider 24 to move towards the guide rail 23. Specifically, the rotation method can be a motor, and in this embodiment, a motor is selected as follows: Figure 2The handwheel 28 is shown. After the nut slider 24 drives the crossbeam 25 connected to one side and the front base plate 26 to move to the preset position, it stops. At this time, the distance between the front base plate 26 and the rear base plate 27 matches the width dimension of the workpiece 100. After placing the workpiece 100 on the front base plate 26, the rear base plate 27, and the wire mesh plate mechanism 1, the position of the workpiece 100 is further fixed by the positioning mechanism 3. Specifically, the first positioning member 31 is installed on the base 21 or the crossbeam 25 and moved toward the workpiece 100, so that the workpiece 100 is pressed against by the multiple first positioning members 31. The workpiece 100 is limited by the multiple first positioning members 31 along the extension direction of the base 21 and the crossbeam 25. Then, similarly, the second positioning member 32 is installed on the base 21 or the crossbeam 25 and moved toward the workpiece 100, so that the workpiece 100 is pressed against by the multiple second positioning members 32. The workpiece 100 is limited by the multiple second positioning members 32 along the extension direction perpendicular to the base 21 and the crossbeam 25. At this time, the workpiece 100 is limited from two directions, realizing precise positioning of the planar angle. Then, the positions of the multiple pressure claws 43 of the clamping mechanism 4 are adjusted so that they are close to the corners of the workpiece 100. The rotary cylinder 41 is then activated to drive the rotating shaft 42, causing the pressure claws 43 to rotate towards the upper surface of the workpiece 100 and apply downward pressure to the upper surface of the workpiece 100. This presses the workpiece 100 onto the wire mesh plate mechanism 1, forming a stable vertical fixation. At this point, the workpiece 100 has completed the positioning on both the horizontal and vertical levels, and the subsequent riveting operation can begin.

[0044] In the above-described process, the adjustment mechanism 2 is used to roughly adjust the position of the platform supporting the workpiece 100, and the positioning mechanism 3 uses multiple first positioning elements 31 and second positioning elements 32 to specifically position the workpiece 100 in the horizontal direction. Therefore, in this embodiment of the invention, the horizontal dimension of the workpiece 100 is flexibly adapted, significantly increasing the range of usable dimensions. A single platform device is used to position workpieces 100 of various sizes, indirectly reducing costs. Finally, the clamping mechanism 4 stably presses the workpiece 100 onto the wire mesh plate mechanism 1. The variable preload of the wire mesh plate mechanism 1 itself enhances the stability of the vertical positioning of the workpiece 100.

[0045] Furthermore, such as Figure 2 As shown, a handwheel 28 is connected to the end of the lead screw 22. 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 low operating cost and can be used with a measuring tape for manual operation, while still achieving high positioning accuracy.

[0046] Further, please see Figure 1 , 25. The adjusting mechanism 2 also includes another symmetrically arranged combination of lead screws 22, guide rails 23, and lead screw nut sliders 24. The combination of the two lead screws 22, guide rails 23, and lead screw nut sliders 24 is connected by a pair of pulleys mounted on each lead screw 22 and a belt 29 between the pulleys, so that the pair of lead screws 22 and the pair of lead screw nut sliders 24 can move synchronously; wherein, the crossbeam 25 is fixed between the pair of lead screw nut sliders 24. With the above structure, in this embodiment, a rectangular bearing frame is actually formed, with a pair of guide rails 23 forming the left and right sides, and the crossbeam 25 and the base 21 forming the upper and lower sides. Based on this, when positioning the workpiece 100, the workpiece can be placed in one corner of the rectangular frame. Specifically, in this embodiment, the positioning mechanism also includes multiple third positioning elements 33, which are slidably mounted on one of the guide rails 23. The third positioning elements 33 are used to limit the edge of the workpiece 100 along the extension direction of the crossbeam 25 and the base 21. The third positioning elements 33 and the first positioning elements 31 are arranged opposite to each other. Figure 1 In the embodiment shown, the workpiece 100 is placed at the lower right corner of the rectangular frame. Therefore, by simply adjusting the position of the crossbeam 25, the workpiece 100 can be positioned from the four sides by means of the joint abutment action of the first positioning member 31, the second positioning member 32, and the third positioning member 33.

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

[0048] Of course, in other embodiments, different numbers of first positioning elements 31, second positioning elements 32, third positioning elements 33 and pressure claws 43 can be set for different stability requirements. As long as the fixed stability requirements are met, they do not deviate from the technical concept of this embodiment.

[0049] Furthermore, such as Figure 3As shown, the wire mesh plate mechanism 1 includes two sliding grooves 11, multiple wire fixing blocks 12, and multiple wires 13. The two sliding grooves 11 are arranged opposite each other, and each end of each wire 13 is connected to a wire fixing block 12. Each wire fixing block 12 is installed in the corresponding sliding groove 11. Before placing the workpiece 100, the tensile strength of the wire 13 can be adjusted by the corresponding two wire fixing blocks 12 according to the load-bearing strength requirements of the workpiece 100, so as to achieve different support forces of the wire 13. Furthermore, the top surfaces of the front base plate 26 and the rear base plate 27 are provided with grooves for accommodating the wires 13. The position of the wires 13 can be adjusted by adjusting the position of the wire fixing blocks 12 in the sliding grooves 11, so that the wires 13 pass through the corresponding grooves, avoiding interference friction between the wires 13 and the front base plate 26 and the rear base plate 27, which would affect the service life of the structure. During the positioning process, the clamping claws 43 of the clamping mechanism 4 press the bottom surface of the workpiece 100 onto the steel wire 13, the front base plate 26 and the rear base plate 27. The steel wire 13 plays the role of elastic support, achieving uniform and stable support and protection. The steel wire 13 in the groove also has a certain elastic space for movement. The front base plate 26 and the rear base plate 27 limit the specific clamping depth of the workpiece 100.

[0050] Further, please see Figure 2 A front measuring tape 261 is installed on one side of the front base plate 26, a rear measuring tape 271 is installed on one side of the rear base plate 27, and a guide rail measuring tape 231 is installed on one side of the guide rail 23. The installation of these measuring tapes near the positioning points of the workpiece 100 allows operators to promptly fine-tune the positioning accuracy of the workpiece 100, preventing positioning deviations.

Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.
