Description
Technical Field
[0001] This application relates to the technical field of riveting equipment, and in particular to a sheet metal riveting equipment. Background Technology
[0002] In the field of sheet metal processing, riveting is a crucial process for securely attaching fasteners such as rivets or nuts to sheet metal parts, and riveting equipment is the core tool for achieving this process. Currently, there are still some issues with sheet metal riveting equipment on the market that require improvement during use.
[0003] In traditional riveting equipment, the position of the riveting mechanism is often fixed. When riveting operations are required at different positions on sheet metal parts, manual movement of the sheet metal parts is usually necessary to facilitate processing. This method not only increases the labor intensity of workers but also makes it difficult to ensure the accuracy of sheet metal part movement, which can easily affect the quality and efficiency of riveting. At the same time, a certain amount of metal shavings and dust are generated during the riveting process. If these shavings and dust are not handled in time, they will scatter on the processing table, affecting subsequent processing operations and requiring frequent cleaning, thus increasing the number of steps. Therefore, to solve the above problems, this application provides a sheet metal riveting device. Utility Model Content
[0004] To address the problems mentioned in the background art, this application provides a sheet metal riveting device.
[0005] This application provides a sheet metal riveting device, including a processing table, a dust removal fan, a dust collection box with an open front sidewall, and a clamping assembly. The surface of the processing table has a horizontal groove, and a servo motor is fixedly connected to the outer sidewall of the processing table. The output end of the servo motor extends into the interior of the horizontal groove and is fixedly connected to a lead screw via a coupling. An L-shaped plate is threaded onto the external side of the lead screw, and a riveting machine is mounted on the top of the L-shaped plate. The exhaust port of the dust removal fan is connected to an exhaust pipe, and a horizontal pipe is connected to the end of the exhaust pipe away from the dust removal fan. Multiple air inlets are connected at equal intervals to the outside of the horizontal pipe, and an exhaust pipe is connected to the exhaust port of the dust removal fan. The end of the exhaust pipe away from the dust removal fan extends into the interior of the dust collection box.
[0006] Preferably, the clamping assembly includes electrically operated telescopic rods symmetrically fixedly connected to the surface of the processing table, and the output ends of both electrically operated telescopic rods are fixedly connected to clamping plates.
[0007] Preferably, the front side wall of the dust collection box is hinged with a door.
[0008] Preferably, the dust removal fan and the dust collection box are both fixedly installed on the front side wall of the processing table.
[0009] Preferably, the bottom of the L-shaped plate is in close contact with the bottom inner wall of the transverse groove, and the bottom of the clamping plate is in close contact with the surface of the processing table.
[0010] In summary, this application includes the following beneficial technical effects:
[0011] 1. Improve the flexibility and efficiency of riveting: By opening a horizontal groove on the surface of the processing table and setting a servo motor, lead screw and L-shaped plate, the servo motor can drive the lead screw to rotate when it is working, which in turn moves the L-shaped plate in the horizontal groove, thereby driving the riveting machine installed on the top of the L-shaped plate to move. This structure can achieve precise adjustment of the position of the riveting machine without the need for manual movement of sheet metal parts, can adapt to the riveting needs of different positions of sheet metal parts, reduce the labor intensity of workers, and effectively improve the flexibility and processing efficiency of riveting.
[0012] 2. Effective dust collection and improved processing environment: The coordinated setup of dust-collecting fans, extraction pipes, horizontal pipes, air intake hoods, and dust collection boxes allows the dust-collecting fans to operate during the riveting process. Multiple air intake hoods simultaneously extract dust and metal debris generated in the riveting area. The extracted dust is then collected in the dust collection box via the extraction and exhaust pipes. This not only prevents dust from scattering on the processing table and affecting subsequent operations, reducing cleaning steps, but also prevents dust from spreading into the air and being inhaled by operators, improving the processing environment and protecting the health of the operators.
[0013] 3. Improve the stability of sheet metal parts: The clamping assembly adopts symmetrically arranged electric telescopic rods and clamping plates. The operation of the electric telescopic rods can push the clamping plates to move, which can stably clamp sheet metal parts of different sizes, improving the processing accuracy and product quality of sheet metal parts.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.
[0019] Example 1:
[0020] A sheet metal riveting device, referring to Figure 1 - Figure 3 The system includes a processing table 1, a dust removal fan 2, a dust collection box 3 with an open front sidewall, and a clamping assembly. The dust removal fan 2 and the dust collection box 3 are both fixedly installed on the front sidewall of the processing table 1. The front sidewall of the dust collection box 3 is hinged with a door 15. A horizontal groove 4 is opened on the surface of the processing table 1. A servo motor 5 is fixedly connected to the outer sidewall of the processing table 1. The output end of the servo motor 5 extends into the interior of the horizontal groove 4 and is fixedly connected to a lead screw 6 through a coupling. An L-shaped plate 7 is threaded onto the outside of the lead screw 6. The bottom of the L-shaped plate 7 is tightly fitted to the bottom inner wall of the horizontal groove 4. A riveting machine 8 is installed on the top of the L-shaped plate 7. The exhaust port of the dust removal fan 2 is connected to an exhaust pipe 9. The end of the exhaust pipe 9 away from the dust removal fan 2 is connected to a horizontal pipe 10. Multiple air inlets 11 are connected at equal intervals to the outside of the horizontal pipe 10. The exhaust port of the dust removal fan 2 is connected to an exhaust pipe 12. The end of the exhaust pipe 12 away from the dust removal fan 2 extends into the interior of the dust collection box 3.
[0021] Specifically, the dust removal fan 2 and the dust collection box 3 are fixed to the front wall of the processing table 1, allowing the dust removal components to form a reasonable layout with the processing area. When dust is generated during riveting, the subsequent dust removal structure can operate efficiently. The door 15, hinged to the front wall of the dust collection box 3, is normally closed to ensure that dust does not leak out. When the dust inside the box accumulates to a certain level, the door 15 can be opened for convenient cleaning. The processing table 1 provides a basic platform for processing operations, and the horizontal grooves 4 on its surface provide guiding space for the movement of the L-shaped plate 7. When the position of the riveting machine 8 needs to be adjusted, the servo motor 5 on the outer wall of the processing table 1 is started. The output end of the servo motor 5 drives the lead screw 6, which extends into the transverse groove 4, to rotate through the coupling. Since the L-shaped plate 7 is threadedly connected to the lead screw 6, and the bottom of the L-shaped plate 7 is tightly fitted to the inner wall of the bottom of the transverse groove 4, restricting its rotation, the rotation of the lead screw 6 is converted into the linear movement of the L-shaped plate 7 along the transverse groove 4, thereby driving the riveting machine 8 installed on the top of the L-shaped plate 7 to move to the required riveting position. A corrugated pipe can be installed on the outside of the lead screw 6 for dust removal. Both ends can be connected to the L-shaped plate 7 or the inner wall of the transverse groove 4 respectively. When the L-shaped plate 7 moves, it will drive the corrugated pipe to contract or stretch accordingly. During this process, the inner wall of the bellows moves relative to the surface of the lead screw 6, which can scrape off the dust and other impurities attached to the surface of the lead screw 6, thus removing the dust from the surface of the lead screw 6 and preventing the dust from affecting the thread transmission accuracy between the lead screw 6 and the L-shaped plate 7. When dust and metal shavings are generated during the riveting process, the dust removal fan 2 is activated. The air intake of the dust removal fan 2 creates a negative pressure inside the horizontal pipe 10 through the air extraction pipe 9. Multiple air intake hoods 11, which are equally spaced outside the horizontal pipe 10, will simultaneously suck in the dust and metal shavings around the riveting area. The sucked-in dust and other impurities enter the dust removal fan 2 through the air extraction pipe 9, and are then transported to the dust collection box 3 for collection through the exhaust pipe 12 from the exhaust port of the dust removal fan 2.
[0022] Reference Figure 1 The clamping assembly includes two electrically telescopic rods 13 that are symmetrically fixedly connected to the surface of the processing table 1. The output ends of the two electrically telescopic rods 13 are fixedly connected to clamping plates 14, and the bottom of the clamping plates 14 is in close contact with the surface of the processing table 1.
[0023] Specifically, when it is necessary to fix the sheet metal parts, the two electric telescopic rods 13 that are symmetrically fixed on the surface of the processing table 1 are activated. The output end of the electric telescopic rod 13 pushes the clamping plate 14 that is fixedly connected to it to move towards the sheet metal parts. Since the bottom of the clamping plate 14 is in close contact with the surface of the processing table 1, the stability of the movement process can be guaranteed. The clamping plates 14 on both sides cooperate with each other to firmly clamp sheet metal parts of different sizes on the processing table 1, preventing shaking and displacement during riveting.
[0024] The implementation principle of a sheet metal riveting device according to an embodiment of this application is as follows: When the sheet metal riveting device is working, the dust removal fan 2, the servo motor 5, and the electric telescopic rod 13 are all electrically connected to an external power source through a switch. The processing table 1 serves as a basic platform to provide operating space. First, the sheet metal part to be processed is placed on the surface of the processing table 1. The two electric telescopic rods 13, which are symmetrically fixed on the surface of the processing table 1, are started by a switch. The electric telescopic rods 13 are preferably of type LX600. The output end of the electric telescopic rods 13 pushes the clamping plate 14 to move towards the sheet metal part. Because the bottom of the clamping plate 14 is in close contact with the surface of the processing table 1, the movement is smooth. The clamping plates 14 on both sides cooperate to firmly hold the sheet metal part. To prevent shaking and displacement during riveting, if the riveting position needs to be adjusted, the servo motor 5 on the outer wall of the processing table 1 is started by the Kaige machine. The servo motor 5 is preferably of type HBS57. Its output end drives the lead screw 6 in the transverse groove 4 to rotate through the coupling. The external thread opening angle of the lead screw 6 is 20 degrees. The thread self-locking condition must meet the following formula calculation: self-locking condition = friction coefficient × tan (helix angle) ≥ 1. Since the L-shaped plate 7 is threadedly connected to the lead screw 6 and its bottom is tightly attached to the bottom inner wall of the transverse groove 4 and is restricted from rotation, the rotation of the lead screw 6 is converted into the linear movement of the L-shaped plate 7 along the transverse groove 4, which in turn drives the riveting machine 8 at the top to move to the required position for riveting. When dust and metal shavings are generated during the riveting process, the dust removal fan 2 on the front wall of the processing table 1 is activated by a switch. The dust removal fan 2 is preferably of type UF12A23BWH. Its air intake creates a negative pressure inside the horizontal pipe 10 through the air intake pipe 9. Multiple air intake hoods 11 at equal intervals outside the horizontal pipe 10 simultaneously suck in dust and other impurities from the riveting area. The impurities enter the dust removal fan 2 through the air intake pipe 9, and are then transported through the exhaust pipe 12 to the dust collection box 3, which is also fixed to the front wall of the processing table 1, for collection. The door 15 of the dust collection box 3, which is hinged to the front wall, is normally closed to prevent dust leakage. It can be opened for cleaning after a certain amount has accumulated.
