Riveting mechanism capable of achieving multi-rivet simultaneous riveting

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-2 , A riveting mechanism that realizes simultaneous riveting of multiple nails, including a base 1, a placement plate 2 is fixedly connected to the upper end of the base 1, and a plurality of first placement grooves 18 are provided on the upper end of the placement plate 2 Both the left and right ends are provided with sliding grooves 3, and two sliding grooves 3 are equipped with matching sliding blocks 4, and the upper ends of the two sliding blocks 4 are fixedly connected with a clamping plate 5, and the opposite side walls of the two clamping plates 5 In contact with each other, one end of the splint 5 is fixedly connected with a rubber strip. The rubber strip is located directly above the first placement groove 18. The lower end of the splint 5 is in contact with the upper end of the placement plate 2, and the two sliding grooves 3 are far away from the first placement groove 18. A clamping member 6 is fixedly connected to the inner wall of one end, and the end of the clamping member 6 close to the first placement groove 18 is fixedly connected to the side wall of the slider 4, and the clamping member 6 includes a first fixedly arranged on the inner wall of the sliding groove 3. Telescopic rod 11, one end of the first telescopic rod 11 close to the first placement slot 18 is fixedly connected to the side wall of the slider 4, the first telescopic rod 11 is sleeved with a first spring 12, the first spring 12 is a strong spring to facilitate It is better to make the clamping plate 5 clamp the rivet, the left and right ends of the first spring 12 are in contact with the inner wall of the sliding groove 3 and the side wall of the sliding block 4 respectively, and the upper end of the base 1 is provided with a plurality of first grooves 19, and The first grooves 19 are symmetrically distributed on the left and right sides of the placement plate 2 respectively.

[0019] A first fixing block 7 is provided directly above the base 1, and the upper end of the first fixing block 7 is provided with a plurality of through holes 20 communicating up and down. The plurality of through holes 20 are respectively located directly above the plurality of first placement grooves 18. Each through hole 20 is provided with a pressing member 8 therethrough, and the upper ends of the plurality of pressing members 8 are fixedly connected to the same second fixing block 9, and the pressing member 8 includes a pressing rod 13 penetratingly arranged in the through hole 20, The upper end of the pressure rod 13 is fixedly connected with the lower end of the second fixing block 9, the lower end of the pressure rod 13 is fixedly connected with a pressure block 14, and the lower end of the pressure block 14 is provided with a second placement groove 22, which is located in the first placement Right above the groove 18, the upper end of the second fixing block 9 is fixedly connected with the pressure column 17 of the external hydraulic press. The lower end of the first fixing block 7 is provided with a plurality of second grooves 21, and the top of the plurality of second grooves 21 All are fixedly connected with a telescopic mechanism 10, the lower ends of the plurality of telescopic mechanisms 10 are respectively fixedly connected to the bottom of the plurality of first grooves 19, the telescopic mechanism 10 includes a second telescopic rod 15 fixedly arranged on the top of the second groove 21, The lower ends of the two telescopic rods 15 are fixedly connected to the bottom of the first groove 19, and the second telescopic rod 15 is sleeved with a second spring 16. The upper and lower ends of the second spring 16 are connected to the top and the first groove of the second groove 21, respectively. The bottom of a groove 19 is in abutting contact.

[0020] In the present invention, the operator first spreads the first fixed block 7 from the base 1 through the telescopic mechanism 10 by hand, and then spreads the splints 5 on both sides of the first placing grooves 18, and places the rivets on the first In the placement groove 18, after the rivets are placed, the clamping plates 5 on the left and right sides of the first placement groove 18 clamp the rivets under the action of the first spring 12 and the sliding block 4. The rubber strips fixed on the clamping plates 5 are enlarged and The friction force of the rivet makes it difficult to shake, and then insert the workpiece to be riveted on multiple rivets, loosen the first fixed block 7, and the external hydraulic machine starts to work so that the pressure column 17 acts on the second fixed block 9. The downward movement of the two fixed blocks 9 drives the pressing rods 13 in the multiple through holes 20 to move downwards. The movement of the pressing rods 13 causes the pressing blocks 14 to move downwards and gradually squeeze the rivets. When squeezed to the bottom layer, the multiplication is completed. For the riveting operation of one rivet and multiple workpieces to be riveted, the second fixed block 9 gradually rises after the extrusion is completed. At this time, the riveted workpiece can be taken out, and new rivets and the workpiece to be riveted can be put in to continue the riveting operation.

[0021] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention Equivalent replacements or changes to its inventive concept should all fall within the protection scope of the present invention.
