Technical Field

[0001] The invention relates to the field of riveting and forming of hardware parts, and in particular to a device capable of continuously riveting rivets of different heights. Background Art

[0002] When the riveting machine is working, the downward pressure is relatively large. The platform supporting the riveting jig needs to be able to withstand a large downward pressure and remain stable. After the height of the riveting machine is adjusted, the height at which the rivet head presses down is fixed each time it works. In this way, when riveting multiple rivets of different heights on the riveted part continuously, it is necessary to adjust the position and height of the riveted part to match the rivet head. In the prior art, when a riveted part needs to be riveted with more than two rivets of different heights, a common practice is to make multiple sets of riveting jigs and use multiple riveting machines to complete the operation. This method will lead to low production efficiency and high equipment costs. Summary of the invention

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] like Figure 2-6 FIG. 1 is a schematic diagram of a device for continuously riveting rivets of different heights according to the present invention, which at least includes a lateral moving assembly and a jig lifting assembly; the lateral moving assembly includes a lateral driving mechanism 11, a guide rail 12 and a first slider 13; the lateral driving mechanism 11 is suitable for driving the first slider 13 to slide along the guide rail 12; the jig lifting assembly includes a fixed plate 21, a driver 22, a second slider 23 and a jig platform 24; the fixed plate 21 and the driver 22 are both fixedly connected to the first slider 13; a vertical guide 25 is provided on the fixed plate 21, and the jig platform 24 is located above the fixed plate 21, and a second slider 23 is arranged between the fixed plate 21 and the jig platform 24. The top surface of the second slider 23 is the first step surface 131, and the bottom surface of the jig platform 24 is the second step surface 241. The first step surface 131 and the second step surface 241 are slidably matched. The driver 22 is suitable for driving the second slider 23 to move on the top surface of the fixed plate 21 to make the jig platform 24 rise or fall along the vertical guide member 25. The top surface of the jig platform 24 is used to support the rivet 33 and the rivets 32 at different heights on the rivet 33.

[0026] Specifically, the top surface of the jig platform 24 is used to support the riveted piece 33 and the rivet 32, which is generally achieved by a riveting jig, that is, the riveting jig is set on the top surface of the jig platform 24, and the riveting jig has support blocks 31 of different heights, and the support blocks 31 of different heights are used to support rivets 32 and riveted pieces 33 of different heights. For further convenience of understanding, Figure 1 Schematic diagram of the riveting fixture, the riveting piece 33 and the rivet 32 ​​is shown in FIG.

[0027] The horizontal position of the jig platform 24 can be adjusted by the lateral moving assembly, so that the rivets 32 at different horizontal positions on the jig platform 24 (generally speaking, the horizontal positions of the rivets 32 at different heights are also different) can all be aligned with the rivet head 411 of the riveting machine 41; the height of the jig platform 24 can be adjusted by the jig lifting assembly, so that the rivets 32 at different heights on the jig platform 24 can all meet the height requirements of the riveting machine 41 during riveting. That is, through the cooperation of the above assemblies, multiple rivets 32 at different heights can be continuously riveted, thereby improving production efficiency. In addition, in the present invention, the rise or fall of the jig platform 24 is achieved by cooperating stepped surfaces, so during the entire riveting process, the jig platform 24 and the final support platform (riveting machine platform 412) are always connected by a support member, that is, the jig platform 24 and the second slider 23 and the fixed plate 21 can be regarded as a force-bearing whole, which is equivalent to the jig platform 24 being fixed on the final support platform (riveting machine platform 412), with a stable structure and high bearing capacity.

[0028] As a preferred embodiment, the transverse driving mechanism 11 includes a motor 111, a screw rod 112 and a nut; the screw rod 112 is arranged parallel to the guide rail 12, the motor 111 is suitable for driving the screw rod 112 to rotate around its own axis, the nut is threadedly matched with the screw rod 112, and the nut is fixedly connected to the first slider 13. Specifically, the motor 111 can be a servo motor 111; and the screw rod 112 transmission has the advantages of stable operation and high precision, which can improve the reliability of the device for continuously riveting rivets of different heights of the present invention during operation.

[0029] Preferably, a bottom plate 26 is fixedly connected to the first slider 13, and the fixed plate 21 and the driver 22 are fixedly connected to the bottom plate 26. By providing the bottom plate 26, it is equivalent to providing a stable support platform for the jig lifting assembly, further improving the reliability of the present invention during operation. In addition, the bottom plate 26 can also protect the first slider 13 to a certain extent, preventing the driver 22, the fixed plate 21 and other components from directly contacting the first slider 13, thereby extending the service life of the first slider 13.

[0030] Preferably, refer to Figure 3 The vertical guide member 25 is a guide post 251. A guide hole is provided on the fixture platform 24. The first end of the guide post 251 is fixedly connected to the fixing plate 21, and the second end of the guide post 251 is slidably fitted in the guide hole. The movement of the fixture platform 24 on the horizontal plane is limited by the limiting effect of the guide post 251, so that it can only move up and down along the guide post 251.

[0031] Preferably, a guide sleeve 252 is provided in the guide hole. By providing the guide sleeve 252, the friction between the guide post 251 and the fixture platform 24 can be reduced, so that the fixture platform 24 moves more smoothly and reduces the sense of retardation.

[0032] Preferably, the driver 22 is a cylinder, and the driving end of the cylinder is fixedly connected to the second slider 23. Of course, in addition to using the cylinder, other telescopic mechanisms can also be used instead, such as a linear motor 111 and the like.

[0033] Preferably, the jig lifting assembly further comprises an elastic member (not shown), which is disposed on the fixing plate 21 and is suitable for providing a downward elastic force to the jig platform 24. After the riveting is completed, the second slider 23 will be driven back by the driver 22 to Figure 3 For example, when the second slider 23 moves to the left, the jig platform 24 needs to descend along the vertical guide member 25 for the next riveting. The downward elastic force provided by the elastic member causes the jig platform 24 to fall back to its original position in addition to its own gravity, thereby ensuring the reliability of the reset of the jig platform 24.

[0034] Preferably, the elastic member is a spring (not shown), a mounting bracket 27 is provided on the fixing plate 21, and a spring is provided between the top of the mounting bracket 27 and the fixture platform 24. That is, the downward elastic force provided by the elastic member is specifically provided by the spring. Specifically, a spring mounting column or a spring mounting hole can also be provided at the spring connection between the mounting bracket 27 and the fixture platform 24 to ensure the reliability of the spring connection.

[0035] Preferably, refer to Figure 4-5 The first step surface 131 includes a plurality of first horizontal surfaces 1311; two adjacent first horizontal surfaces 1311 are connected by a first inclined surface 1312, and the angle between the first inclined surface 1312 and the first horizontal surface 1311 is an obtuse angle. The second step surface 241 includes a plurality of second horizontal surfaces 2411; two adjacent second horizontal surfaces 2411 are connected by a second inclined surface 2412, and the second inclined surface 2412 is parallel to the first inclined surface 1312. The obtuse angle between the first inclined surface 1312 and the first horizontal surface 1311, and the second inclined surface 2412 is parallel to the first inclined surface 1312, can ensure the smoothness of sliding between the first step surface 131 and the second step surface 241.

[0036] It should be noted that the height difference between two adjacent first horizontal surfaces 1311 should be equal to the height difference between two corresponding rivets 32 of different heights. Further, when the first stepped surface 131 and the second stepped surface 241 slide against each other, at least one second level abuts against the first horizontal surface 1311 .

[0037] The working process of the present invention is as follows:

[0038] After the riveted part 33 and the rivet 32 ​​are assembled, they are placed on a riveting jig, and the assembly is moved laterally so that the rivet A on the riveted part 33 (the first rivet to be riveted) is moved to the bottom of the riveting head of the riveting machine 41 to start riveting;

[0039] After the riveting of rivet A is completed, rivet B (the second rivet to be riveted) is moved to the bottom of the riveting head of the riveting machine 41 by the lateral moving assembly, and then the jig platform 24 is raised by the jig lifting assembly (the height of the jig platform 24 is equal to the height difference between rivet A and rivet B), so that rivet B can reach the riveting height of the riveting machine 41;

[0040] This process is repeated in this way until the rivets 32 at different heights on the riveted part 33 are riveted.

[0041] After the riveting is completed, the driver 22 drives the second slider 23 to retract, and the fixture platform 24 falls back to the initial position under the action of its own weight and the reset spring, completing the reset, and at the same time taking out the riveted part 33.

[0042] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
