Abstract
Description
Technical Field
[0001] The present application relates to the technical field of hinge riveting, and in particular to an automatic hinge riveting machine. Background Art
[0002] Riveting and welding are two well-known ways of connecting multiple plates. Riveting is a non-detachable connection that uses rivets to connect the riveted parts together. It has a long history of application in the fields of building structures and mechanical manufacturing. When riveting, first insert the rivet into the rivet hole of the riveted part, and use the rivet head of the riveting machine to punch or roll the rivet to deform the rivet, thereby completing the riveting.
[0003] The existing riveting machine uses the rivet head of the riveting machine to quickly punch the rivet to deform it, thereby completing the riveting work. However, since the riveting machine only relies on the function of the riveting machine itself when punching the rivet, it takes multiple repeated punching operations to fix the component stably. Multiple punching operations will not only increase the wear of the workpiece, but also reduce the production efficiency of the finished product, which is not conducive to the rapid production of the workpiece.

[0017] The following is combined with Figure 1-3 This application is described in further detail.
[0018] The present application embodiment discloses a hinge automatic riveting machine, referring to Figure 1-Figure 2 , including a base plate 1, a support frame 2 is fixedly installed above the base plate 1, a workbench 3 and a riveting member 4 are arranged between the base plate 1 and the support frame 2, the riveting member 4 is located above the workbench 3, the riveting member 4 is connected to the support frame 2 through a lifting assembly, two groups of clamping plates 7 are arranged above the riveting member 4, an adjusting assembly is arranged between the two groups of clamping plates 7, the adjusting assembly drives the two groups of clamping plates 7 to move closer to or away from each other, and drives the workbench 3 to move up and down.
[0019] The lifting assembly includes a support plate 5 and an electric push rod 6. The electric push rod 6 is fixedly installed above the support frame 2. The output end of the electric push rod 6 passes through the support frame 2 and extends to the bottom of the support frame 2. The support plate 5 is fixedly installed at the output end of the electric push rod 6. The support plate 5 and the upper end of the rivet 4 are detachably connected.
[0020] In this embodiment, the workpiece is placed above the workbench 3. Under the action of the support frame 2, the electric push rod 6 is connected to the external power supply. The electric push rod 6 drives the riveting part 4 to move downward through the support plate 5. At the same time, under the action of the adjustment component, the adjustment component drives the two sets of clamps 7 to approach each other, limit the workpiece, and drive the workbench 3 to move upward on the base plate 1, so that the riveting part 4 can rivet the workpiece.
[0021] Reference Figure 2-Figure 3 The adjustment component includes a mounting plate 8 and a threaded rod 11. The mounting plate 8 is slidably inserted above the workbench 3. The mounting plate 8 is connected to the two sets of clamping plates 7 away from one side through an elastic structure. A push plate 14 is arranged between the mounting plate 8 and the base plate 1. One end of the push plate 14 is rotatably connected to the base plate 1, and the other end of the push plate 14 is rotatably connected to the mounting plate 8. The push plate 14 is inclined. The threaded rod 11 is rotatably inserted into the inside of the workbench 3. The threaded rod 11 is threadedly connected to the mounting plate 8, and the threaded rod 11 is connected to the support plate 5 through a rotating structure.
[0022] The elastic structure includes a slide bar 9 and a spring 10. The slide bar 9 slides through the mounting plate 8. The slide bar 9 is fixedly connected to the clamping plate 7. The spring 10 is movably sleeved on the outside of the slide bar 9. The spring 10 is located between the clamping plate 7 and the mounting plate 8.
[0023] The rotating structure includes a gear 12 and a rack 13 . The gear 12 is fixedly sleeved on the outside of the threaded rod 11 . The rack 13 is fixedly installed below the support plate 5 . The gear 12 and the rack 13 are meshed.
[0024] Specifically, when the support plate 5 moves downward, it drives the rack 13 to move synchronously. Since the rack 13 and the gear 12 are meshed, the rack 13 can drive the threaded rod 11 to rotate through the gear 12. Since the threaded rod 11 is threadedly connected to the mounting plate 8, the threaded rod 11 can drive the two groups of mounting plates 8 to approach each other, thereby driving the two groups of clamping plates 7 to approach each other.
[0025] At the same time, when the two groups of mounting plates 8 are close to each other, the upper ends of the two groups of push plates 14 can be driven to approach each other, thereby driving the push plates 14 to rotate, and the push plates 14 push the workbench 3 to move upward on the bottom plate 1.
[0026] When the clamping plate 7 contacts the workpiece, the two sets of mounting plates 8 continue to approach each other, thereby driving the mounting plates 8 to slide outside the slide rod 9. At this time, the spring 10 is compressed, so that workpieces of different sizes can be processed, and the application range of the device is wider.
