Abstract
Description
Technical Field
[0001] This application relates to the field of riveting device technology, and more particularly to a simple riveting device. Background Technology
[0002] In workshop production scenarios, the assembly of various small parts is often involved. These small parts are mostly metal or non-metal components with small structural dimensions and light weight, such as miniature connectors, small brackets, and thin sheet metal parts. They are widely used in the manufacturing process of electronic equipment, instruments, and small machinery. In the assembly of small parts, riveting is one of the key processes. Its core purpose is to fix two or more parts together with rivets to form a stable and non-removable (or removable in a specific way) assembly structure. Compared with welding, which can easily cause thermal deformation of small parts and loosening of threaded connections, riveting can ensure the connection strength while avoiding damage to small parts. It also does not require additional thread processing or welding beveling and is suitable for the structural characteristics of small parts.
[0003] Currently, riveting operations commonly used in workshops rely on large riveting equipment. This type of equipment is bulky and occupies a lot of space. When riveting small parts, not only is it inconvenient to move the equipment and it is difficult to flexibly adapt to the dispersed assembly needs of small parts, but it also has the problems of complex equipment debugging and high energy consumption per operation. At the same time, the manufacturing and maintenance costs of large riveting equipment are high. For small-batch, multi-specification small parts riveting scenarios, the equipment utilization rate is low, resulting in resource waste. Utility Model Content
[0004] In view of the above-mentioned problems existing in the prior art, the main purpose of this application is to provide a simple riveting device.
[0005] The technical solution of this application is as follows: a simple riveting device, including a workbench, a base plate fixedly installed on the top of the workbench, a workpiece disposed on the top of the base plate, riveting holes being opened on both sides of the workpiece, riveting components being riveted into the riveting holes, a riveting assembly for riveting operation being disposed on the top of the base plate, a control assembly for controlling the riveting action being disposed at the bottom of the workbench, and a limiting assembly for maintaining stable stroke being disposed inside the riveting assembly.
[0006] In a preferred embodiment, the riveting assembly includes a guide sleeve fixedly mounted on the top of the substrate. A circular groove is provided inside the guide sleeve, and a pressing slider is slidably connected inside the circular groove. A riveting head is provided at the top of the pressing slider, and an adjusting bolt is fixedly connected to one side of the riveting head. A riveting backing plate is fixedly connected to one end of the top of the guide sleeve.
[0007] By adopting the above technical solution, the pressing slider slides along the inner wall of the circular groove, thereby pressing the riveted part into the riveting hole in the workpiece.
[0008] In a preferred embodiment, the riveting assembly further includes a return spring disposed inside the circular groove, the return spring abutting against the inner wall of the circular groove between the pressing slider and the circular groove.
[0009] By adopting the above technical solution, the reset spring can automatically push the pressure slider to reset, eliminating the need for manual reset and reducing operation steps.
[0010] In a preferred embodiment, the control component includes a foot switch located under the workbench, a pressure sensor fixedly mounted on the outer wall of the foot switch, a controller fixedly mounted on the outer side of the workbench, and a hydraulic cylinder fixedly mounted on the top of the base plate and on one side of the guide sleeve.
[0011] By adopting the above technical solution and setting up a pressure sensor, the pedaling pressure can be monitored in real time and the signal can be transmitted to the controller, which then controls the hydraulic cylinder to start and stop.
[0012] In a preferred embodiment, the limiting component includes a limiting member fixedly connected to the top of the pressing slider, the guide sleeve has a limiting groove inside that cooperates with the limiting member, and the adjusting bolt is threadedly connected to the limiting member.
[0013] By adopting the above technical solution, and through the sliding cooperation between the limiting component and the limiting groove, it can be ensured that the pressing slider maintains a stable stroke during the movement.
[0014] In a preferred embodiment, the piston rod of the hydraulic cylinder extends into the interior of the circular groove and contacts the pressing slider, and the riveting head is magnetically attached.
[0015] By adopting the above technical solution, it is convenient to adsorb the riveted parts.
[0016] In a preferred embodiment, both the pressure sensor and the hydraulic cylinder are electrically connected to the controller.
[0017] By adopting the above technical solution and configuring the controller, the pressure sensor and hydraulic cylinder can be controlled to start and stop.
[0018] Compared with the prior art, the advantages and positive effects of this application are as follows: 1. In this application, the device uses a workbench as the basic carrier, which does not require a large amount of workshop space. It can be flexibly placed in different work areas of the workshop according to the needs of small parts being assembled in a dispersed manner, thus eliminating the dependence of large equipment on fixed installation sites. When performing riveting operations, the workpiece only needs to be placed on the base plate, aligning the riveting hole with the riveting head. Then, the pressing slider slides along the inner wall of the circular groove, thereby riveting the part into the riveting hole in the workpiece. After a single riveting operation is completed, the pressing slider can be automatically pushed to reset by the setting of the return spring, eliminating the need for manual reset, reducing operation steps, shortening the single operation cycle, and eliminating the need for complicated equipment debugging processes. It is especially suitable for riveting operations of small parts in multiple batches and with different characteristics in the workshop.
[0019] 2. In this application, by setting up a pressure sensor, the stepping pressure can be monitored in real time and the signal is transmitted to the controller. The controller controls the piston rod of the hydraulic cylinder to extend and retract, so that the operator does not need to operate the equipment with both hands at the same time, freeing up both hands to stabilize the workpiece, reducing the difficulty of operation and safety risks.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0023] Reference Figure 1-4A simple riveting device includes a workbench 1, a base plate 2 fixedly mounted on the top of the workbench 1, a workpiece 6 on the top of the base plate 2, riveting holes 7 on both sides of the workpiece 6, riveting parts 8 riveted inside the riveting holes 7, a riveting assembly 3 for riveting operation on the top of the base plate 2, a control assembly 4 for controlling the riveting action on the bottom of the workbench 1, and a limit assembly 5 for maintaining stable stroke inside the riveting assembly 3.
[0024] Specifically, the riveting assembly 3 includes a guide sleeve 31 fixedly installed on the top of the base plate 2. A circular groove 33 is formed inside the guide sleeve 31, and a pressing slider 34 is slidably connected inside the circular groove 33. A riveting head 35 is located at the top of the pressing slider 34. During riveting operations, the workpiece 6 is simply placed on the base plate 2, aligning the riveting hole 7 with the riveting head 35. Then, the pressing slider 34 slides along the inner wall of the circular groove 33, thereby riveting the workpiece 8 into the riveting hole 7 in the workpiece 6. After a single riveting operation is completed, the pressing slider 34 is automatically pushed back to its original position by the return spring 36, eliminating the need for manual reset. This reduces operation steps, shortens the single operation cycle, and eliminates the need for complex equipment debugging processes. It is particularly suitable for riveting operations involving multiple batches and variations of small parts in a workshop. An adjusting bolt 37 is fixedly connected to one side of the riveting head 35, allowing for adjustments based on the different parts. The required riveting depth can be adjusted by rotating the adjusting bolt 37 to adjust the position of the riveting head 35. A riveting backing plate 32 is fixedly connected to one end of the top of the guide sleeve 31. The riveting assembly 3 also includes a return spring 36 set inside the circular groove 33. The return spring 36 abuts against the inner wall of the pressing slider 34 and the circular groove 33. The control assembly 4 includes a foot switch 41 set under the worktable 1. The pressure sensor 42 can monitor the stepping pressure in real time and transmit the signal to the controller 43. The controller 43 controls the piston rod of the hydraulic cylinder 44 to extend and retract, so that the operator does not need to operate the equipment with both hands at the same time, freeing up both hands to stabilize the workpiece 6, reducing the difficulty of operation and safety risks. The pressure sensor 42 is fixedly installed on the outer wall of the foot switch 41. The controller 43 is fixedly installed on the outer side of the worktable 1. The hydraulic cylinder 44 is fixedly installed on the top of the base plate 2 and on one side of the guide sleeve 31.
[0025] Specifically, the limiting component 5 includes a limiting member 52 fixedly connected to the top of the pressing slider 34. The guide sleeve 31 has a limiting groove 51 inside that works with the limiting member 52. Through the sliding cooperation between the limiting member 52 and the limiting groove 51, it can be ensured that the pressing slider 34 maintains a stable stroke during movement, preventing the riveting head 35 from deviating. The adjusting bolt 37 is threadedly connected to the limiting member 52. The piston rod of the hydraulic cylinder 44 extends into the interior of the circular groove 33 and contacts the pressing slider 34. The riveting head 35 is magnetically attached to facilitate the adsorption of the riveting part 8. The pressure sensor 42 and the hydraulic cylinder 44 are both electrically connected to the controller 43.
[0026] Working principle: First, during the riveting operation, the worker can place the workpiece 6 on the base plate 2, aligning the riveting hole 7 with the riveting head 35. Then, the worker steps on the foot switch 41. The pressure sensor 42 monitors the stepping pressure in real time and transmits the signal to the controller 43. The controller 43 precisely controls the output force of the hydraulic cylinder 44, causing the piston rod of the hydraulic cylinder 44 to extend and retract. This causes the pressing slider 34 to slide along the inner wall of the circular groove 33, thereby riveting the workpiece 8 into the riveting hole 7 in the workpiece 6. After a single riveting operation is completed, the return spring 36 automatically pushes the pressing slider 34 to reset, eliminating the need for manual reset. This reduces the number of operation steps, shortens the single operation cycle, and eliminates the need for complex equipment debugging procedures. It is especially suitable for riveting operations of small parts in multiple batches and with different characteristics in a workshop.
