Description

Technical Field

[0001] This invention relates to the field of rivet gun technology, and specifically to a rivet gun with force control function. Background Technology

[0002] Riveting guns are used for fastening and riveting various metal sheets and pipes in the manufacturing industry. They are widely used in riveting of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. Developed to address the shortcomings of welding nuts to thin metal sheets and pipes, such as easy melting and stripping of internal threads, rivet guns can rivet products that do not require internal threads or welding nuts, providing strong and efficient riveting, and are convenient and quick to use. Currently, when riveting, the piston rod moves during the riveting motion. The riveting gun stops when the piston rod touches the stop sensor, and the user then operates the rivet gun to reverse and unrive. This riveting method cannot adapt to rivets of different lengths and the materials and thicknesses of the riveting plates. When riveting short rivets, the long riveting distance can easily damage the rivets. When riveting long rivets or when riveting plates are hard or thick, the riveting force of the rivet gun is insufficient, easily leading to weak riveting. Summary of the Invention

When the drive control rod moves in the opening direction in the pressure regulating chamber, it drives the riveting control rod to move in the closing direction through pressure, thereby stopping the riveting gun from riveting. The drive control rod is provided with a second return spring, which is used to reset the drive control rod after riveting is completed.

[0015] 2. This invention increases the pressure in the riveting unriveting assembly by using the airflow variable valve of the pressure regulating component, making the pressure in the riveting unriveting assembly greater than the pressure in the riveting assembly.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0025] like Figure 1 As shown, a rivet gun with force control function is used to drive the riveted parts to perform riveting work, including: The base assembly 1 is provided with a force control system 4, which is used to control the rivet gun to perform riveting, pulling, and unriveting on the riveted parts, and can automatically unrive after the rivet gun pulls the riveting. A handle assembly 2 is disposed above the base assembly 1, and the handle assembly 2 is used to pick up the rivet gun; The gun body assembly 3 is located above the handle assembly 2. The handle assembly 2 contains a drive assembly 5, which can drive the rivet gun to move under the control of the force control system 4. The handle assembly 2 is provided with a transmission channel for energy transmission between the force control system 4 and the drive assembly 5.

[0026] In other words, the rivet gun is mainly composed of a base assembly 1, a handle assembly 2, a gun body assembly 3, a drive assembly 5, a force control system 4, and a delivery channel. The base assembly 1, handle assembly 2, and gun body assembly 3 together form the main structure of the rivet gun. The gun body assembly 3 is installed above the handle assembly 2, with its front end tilted upwards and its middle part connected to the handle assembly 2. The base assembly 1 is cylindrical, and its upper surface is concentrically installed below the handle assembly 2. The handle assembly 2 is equipped with a switch assembly 21, which is used to open or close the rivet gun.

[0027] In addition, the force control system 4 is located in the base assembly 1 and is used to control the rivet gun to operate continuously, so that the rivet gun performs riveting, riveting and retraction in sequence to realize the riveting of the riveted parts. The drive assembly 5 is located in the gun body assembly 3. Under the control of the force control system 4, the drive assembly 5 drives the rivet gun head to perform riveting and retraction, as well as the forward and reverse rotation of the rivet gun. The conveying channel is located in the handle assembly 2 and is used to deliver the gas output by the force control system 4 to the drive assembly 5, so that the drive assembly 5 can move accordingly according to the gas output by the force control system 4.

[0028] In other words, the base assembly 1 in this application is mainly equipped with a force control system 4. The control energy output by the force control system 4 is transmitted through the transmission channel in the handle assembly 2, so that the control energy is transmitted to the drive assembly 5 in the gun body assembly 3. The drive assembly 5 is operated by the control energy to rotate forward or reverse, that is, the rivet gun performs riveting or riveting.

[0029] It should be noted that this application does not limit the specific structure of the force control system 4. It can be reasonably selected according to the actual situation, as long as it can realize the automatic unriveting of the rivet gun after the rivet gun is pulled.

[0030] Specifically, such as Figures 2 to 8 As shown, in this embodiment, the force control system 4 includes: The riveting control component 42 is used to control the riveting gun to perform riveting. The riveting control assembly 44 is used to control the rivet gun to reverse so that the riveted parts are separated from the rivet gun; The pressure regulating component 43 is used to regulate the air pressure of the riveting control component 42 and the riveting unriveting control component 44, so that the riveting unriveting control component 44 will automatically open after the pressure inside the riveting control component 42 reaches a certain level. When the air pressure in the unriveting control component 44 is higher than that in the riveting control component 42, the rivet gun begins to reverse.

[0031] In other words, the force control system 4 consists of a riveting control component 42, a riveting unriveting control component 44, and a pressure regulating component 43. The pressure regulating component 43 is located between the riveting control component 42 and the riveting unriveting control component 44, and its two ends are connected to the riveting control component 42 and the riveting unriveting control component 44 respectively. When the rivet gun is operating, the pressure regulating component 43 adjusts the air pressure between the riveting control component 42 and the riveting unriveting control component 44. When the pressure of the riveting control component 42 reaches a certain value, the pressure regulating component 43 can control the pressure inside the riveting unriveting control component 44 to be greater than the pressure inside the riveting control component 42, thereby closing the riveting control component 42 and controlling the riveting gun to unrive the rivet.

[0032] Furthermore, in this embodiment, the pressure in the riveting control assembly 42 and the riveting release control assembly 44 is controlled by air pressure regulation, thereby controlling the opening and closing of the riveting control assembly 42 and the riveting release control assembly 44. Gas is introduced into the riveting control assembly 42 and the riveting release control assembly 44. The gas pressure first drives the riveting control assembly 42 to work, causing the rivet gun to rivet. After the riveting pressure of the rivet gun reaches a certain level, the gas pressure drives the riveting release control assembly 44 to work. Under the coordination of the pressure regulating assembly 43, the riveting release control assembly 44 stops the riveting control assembly 42 from working, and controls the rivet gun to reverse, causing the riveted parts to separate from the rivet gun.

[0033] It should be noted that the specific structure of the pressure regulating component 43 is not limited in this application. It can be reasonably selected according to the actual situation. Specifically, in this embodiment, the pressure regulating component 43 can be adjusted by air pressure or hydraulic pressure. As long as it can be realized that when the riveting control component 42 reaches a certain pressure, the riveting unriveting control component 44 can start and stop the riveting control component 42.

[0034] Furthermore, such as Figures 2 to 8 As shown, in this embodiment, the pressure regulating component 43 includes a pressure regulating chamber 431, which is connected to an air supply chamber 41. The pressure regulating chamber 431 is provided with a forward rotation pipe 413 and a pressure regulating pipe 411. The forward rotation pipe 413 is located on the handle assembly 2 and is connected to the drive assembly 5, used to control the drive assembly 5 to drive the riveting gun to rivet. The pressure regulating pipe 411 is located on the base assembly 1 and the handle assembly 2 and is connected to the riveting control assembly 42 and the riveting unriveting control assembly 44, used to control the operation of the riveting control assembly 42 and the riveting unriveting control assembly 44.

[0035] Specifically, in this embodiment, the pressure regulating chamber 431 is a cylindrical chamber. One side of the pressure regulating chamber 431 is connected to the gas supply chamber 41, which can supply high-pressure gas to the pressure regulating chamber 431. The pressure regulating chamber 431 is connected to the forward rotation pipe 413 and the pressure regulating pipe 411. The gas in the pressure regulating chamber 431 is respectively connected to the drive assembly 5, the riveting control assembly 42, and the riveting unriveting control assembly 44 through the forward rotation pipe 413 and the pressure regulating pipe 411, so as to make the drive assembly 5, the riveting control assembly 42, and the riveting unriveting control assembly 44 operate.

[0036] In other words, gas is supplied from the air supply chamber 41 to the pressure regulating chamber 431. Part of the gas in the pressure regulating chamber 431 is supplied to the drive assembly 5 through the forward rotation pipe 413, thereby causing the drive assembly 5 to work and control the riveting gun to rotate forward. The other part is supplied to the riveting control assembly 42 and the riveting unriveting control assembly 44 through the pressure regulating pipe 411, thereby causing the riveting gun to rivet and unrivet.

[0037] It should be noted that this application does not limit the specific structure of the riveting control component 42. It can be reasonably selected according to the actual situation, as long as it can drive the rivet to rivet.

[0038] Furthermore, such as Figures 2 to 8 As shown, in this embodiment, the riveting control assembly 42 includes a riveting control rod 422 and a riveting cylinder 421 disposed on one side of the pressure regulating chamber 431. The riveting control rod 422 moves within the pressure regulating chamber 431 to control the opening and closing of the connection between the pressure regulating chamber 431 and the riveting cylinder 421. The pressure regulating pipe 411 is used to drive the riveting control rod 422 to move. A first return spring 423 is provided on the riveting control rod 422 to reset the riveting control rod 422. The output end of the riveting cylinder 421 passes through the handle assembly 2 and is connected to an oil passage pipe. The oil passage pipe is eccentrically inclined and connected to the drive assembly 5. The riveting cylinder 421 is used to drive the riveting gun to perform riveting.

[0039] Specifically, a riveting control rod 422 is provided on one side of the pressure regulating chamber 431. The riveting control rod 422 can move within the pressure regulating chamber 431. The pressure regulating chamber 431 is connected to a riveting cylinder 421 at one end of the riveting control rod 422. The gas pressure in the pressure regulating pipe 411 pushes the riveting control rod 422 to move within the pressure regulating chamber 431, which can open the connecting pipe between the pressure regulating chamber 431 and the riveting cylinder 421, allowing the gas supplied by the gas supply chamber 41 to enter the riveting cylinder 421. The gas pushes the piston rod of the riveting cylinder 421 to move, driving the riveting gun to rivet. After riveting is completed, the elastic force generated by the compression of the first return spring 423 can drive the riveting control rod 422 to return to its original position.

[0040] In other words, the gas pressure in the pressure regulating pipe 411 drives the riveting control rod 422 to move. The riveting control rod 422 moves in the pressure regulating chamber 431, thereby connecting the pressure regulating chamber 431 with the riveting cylinder 421. This allows the gas supplied by the gas supply chamber 41 to enter the riveting cylinder 421, which in turn drives the riveting gun to perform riveting work.

[0041] It should be noted that this application does not limit the specific structure of the rivet control rod 422 moving within the pressure regulating chamber 431. A reasonable choice can be made according to the actual situation. Specifically, the rivet control rod 422 can slide in the form of gears, rollers, or balls, as long as the rivet control rod 422 can move within the pressure regulating chamber 431.

[0042] Furthermore, such as Figures 2 to 8 As shown, in this embodiment, the riveting control assembly 44 includes a drive control rod 441 disposed on one side of the pressure regulating chamber 431. The drive control rod 441 moves within the pressure regulating chamber 431. A reversing pipe 412 is provided between the pressure regulating chamber 431 and the drive assembly 5. The reversing pipe 412 is disposed on the handle assembly 2. The drive control rod 441 is used to control the opening and closing of the reversing pipe 412, thereby causing the drive assembly 5 to reverse.

[0043] The pressure regulating assembly 43 further includes an airflow variable valve 432 disposed in the pressure regulating pipe 411 connected to the riveting unriveting control assembly 44. The airflow variable valve 432 is used to allow the air pressure in the pressure regulating pipe 411 to reach a certain value and then be introduced into the riveting unriveting control assembly 44. The pressure regulating pipe 411 is used to drive the drive control rod 441 to move. When the drive control rod 441 moves in the opening direction in the pressure regulating chamber 431, it drives the riveting control rod 422 to move in the closing direction through pressure, so as to stop the riveting gun from riveting. The drive control rod 441 is provided with a second return spring 442, which is used to reset the drive control rod 441 after riveting is completed.

[0044] Specifically, the drive control lever 441 is located on one side of the pressure regulating chamber 431 and can move within the pressure regulating chamber 431. A reversing pipe 412 is opened on the pressure regulating chamber 431 on one side of the drive control lever 441, which connects to the drive assembly 5. The drive control lever 441 can open or close the reversing pipe 412 by moving within the pressure regulating chamber 431. The airflow variable diameter valve 432 is located within the pressure regulating pipe 411, which is connected to the riveting unriveting control assembly 44. After the air pressure in the pressure regulating pipe 411 reaches a certain value, the airflow variable diameter valve 432 is introduced into the riveting unriveting control assembly 44. The gas pressure pushes the drive control lever 441 to move within the pressure regulating chamber 431, opening the reversing pipe 412, so that the gas in the air supply chamber 41 enters the drive assembly 5 through the reversing pipe 412, causing the drive assembly 5 to reverse the riveting gun for riveting unriveting.

[0045] In other words, when the gas pressure in the pressure regulating pipe 411 of the riveting control assembly 44 reaches a certain level after passing through the airflow reducer valve 432, it will push the drive control rod 441 to move. Due to the high pressure at the drive control rod 441 in the pressure regulating chamber 431, the drive control rod 441 moves in the opening direction, which will cause the riveting control rod 422 to move in the closing direction. Finally, the pressure regulating chamber 431 is connected to the drive assembly 5, and the pressure regulating chamber 431 is connected to the riveting cylinder 421 and closed, so that the gas supplied by the air supply chamber 41 enters the drive assembly 5, causing the drive assembly 5 to drive the riveting gun to reverse, thereby removing the riveting from the riveted parts. After the riveting gun removes the riveting, the elastic force generated by the compression of the second return spring 442 will push the drive control rod 441 to return to its original position.

[0046] It should be noted that this application does not limit the specific structure of the drive control lever 441 moving within the pressure regulating chamber 431. A reasonable choice can be made according to the actual situation. Specifically, the drive control lever 441 can slide in the form of gears, rollers, or balls, as long as the drive control lever 441 can move within the pressure regulating chamber 431.

[0047] Furthermore, such as Figures 2 to 4 As shown, in this embodiment, the force control system 4 further includes a force control component 45. The force control component 45 can adjust the riveting force of the rivet gun on the riveted part. The force control component 45 includes an adjusting rod 451 and a pressure rod 452. One end of the pressure rod 452 extends into the air supply chamber 41 and slides within the air supply chamber 41. The adjusting rod 451 is used to adjust the volume of the pressure rod 452 within the air supply chamber 41, thereby increasing the air pressure within the air supply chamber 41 and adjusting the riveting force of the rivet gun.

[0048] Specifically, the force control component 45 includes a force control housing. An adjusting rod 451 and a pressure rod 452 are respectively provided at both ends inside the force control housing. The adjusting end of the adjusting rod 451 extends out of the force control housing and is threadedly connected to the force control housing. One end of the pressure rod 452 extends out of the force control housing and enters the air supply chamber 41. The pressure rod 452 is slidably connected to the force control housing. A force control spring is provided inside the force control housing, and both ends of the force control spring are connected to the adjusting rod 451 and the pressure rod 452 respectively.

[0049] In other words, by rotating the end of the adjusting rod 451 located outside the force control housing, since the adjusting rod 451 is threadedly connected to the force control housing, the adjusting rod 451 moves within the force control housing to compress the force control spring. The elastic force generated by the compression of the force control spring pushes the pressure rod 452 to slide within the force control housing, causing the pressure rod 452 to slide into the air supply chamber 41. This reduces the gas volume within the air supply chamber 41, thereby increasing the air pressure output from the air supply chamber 41. This increases the gas pressure entering the riveting cylinder 421, thereby increasing the riveting force of the rivet gun on the rivet, thus achieving the adjustment of the riveting force of the rivet gun and enabling the rivet gun to rivet parts with different signals.

[0050] It should be noted that this application does not limit the specific structure of the conveying channel, and a reasonable selection can be made according to the actual situation. Specifically, the conveying channel can be a circular pipe, an inclined hole pipe, a connected chamber, or a gap between components, as long as it can realize the energy transmission between the force control system 4 and the drive component 5.

[0051] Specifically, such as Figures 2 to 8 As shown, in this embodiment, the conveying channel includes a forward rotation pipe 413, a pressure regulating pipe 411, a reverse rotation pipe 412, and an oil circuit pipe. The handle assembly 2 is provided with a switch assembly 21, which includes a switch trigger and a ball valve. The switch trigger is used to open or close the ball valve. The ball valve is located on the pressure regulating pipe 411. The reverse rotation pipe 412 conveys through the gap between the output end of the riveting cylinder 421 and the handle assembly 2. The output end of the riveting cylinder 421 is connected to the oil circuit pipe for conveying. The oil circuit pipe has an eccentric inclined hole that connects to the gun body assembly 3 to drive the riveting process.

[0052] In other words, the conveying channel mainly consists of a forward rotation pipe 413, a pressure regulating pipe 411, a reverse rotation pipe 412, and an oil circuit pipe. The forward rotation pipe 413 and the pressure regulating pipe 411 are circular pipes for gas conveying. The circular pipes are located inside the outer shell of the handle assembly 2. The oil circuit pipe is a slanted hole pipe, which is intended to avoid the problem of gas and oil leakage caused by puncture due to proximity to the forward rotation pipe 413 and the pressure regulating pipe 411. The reverse rotation pipe 412 is the gap between the output end of the riveting cylinder 421 and the outer shell of the handle assembly 2, so that the gas transmission speed in the reverse rotation pipe 412 is faster.

[0053] It should be noted that this application does not limit the specific structure of the drive component 5, and a reasonable selection can be made according to the actual situation, as long as the drive component 5 can drive the rivet gun to rotate forward or backward.

[0054] Specifically, such as Figures 5 to 11 As shown, in this embodiment, the driving component 5 includes a housing, one end of which is connected to a rivet gun head. The rivet gun head is used to connect with the riveting component. A driving component 51 is provided inside the housing. The driving component 51 is used to drive the rivet gun head to rotate. The forward rotation pipe 413 and the reverse rotation pipe 412 are both connected to the housing. The gas supplied by the air supply chamber 41 is used to provide power to the driving component 51.

[0055] In other words, the drive unit 51 is installed inside the housing, and the output end of the drive unit 51 is connected to the head of the rivet gun. The head of the rivet gun is provided with threads for connecting to the riveting parts. The forward rotation pipe 413 and the reverse rotation pipe 412 are connected to the housing, so that the gas supplied by the air supply chamber 41 can enter the drive unit 51 and serve as the driving force to make the drive unit 51 operate.

[0056] It should be noted that this application does not limit the specific structure of the drive component 51. It can be reasonably selected according to the actual situation. Specifically, the drive component 51 can be a pneumatic motor or a servo motor. When it is a servo motor, it is only necessary to install a gas sensor to start the servo motor while gas is introduced into the drive component 5. As long as the drive component 51 can drive the riveting gun to rotate forward or backward, it is acceptable.

[0057] Specifically, such as Figures 9 to 11 As shown, in this embodiment, the driving member 51 is provided with a forward rotation air hole 511 and a reverse rotation air hole 512. The forward rotation air hole 511 and the reverse rotation air hole 512 are respectively connected to the forward rotation pipe 413 and the reverse rotation pipe 412. The forward rotation air hole 511 is connected to a forward rotation chamber 513. The forward rotation chamber 513 is opened on one side of the driving member 51 and is used to cooperate in driving the riveting gun to perform forward rotation riveting. A first exhaust hole 514 is provided on one side of the forward rotation chamber 513 and is connected to the forward rotation chamber 513. One end of the drive component 51 is connected to a reverse fan blade 52. The drive component 51 is provided with a second exhaust port 515. The second exhaust port 515 is provided with a slidably disposed exhaust piston. An exhaust return spring is connected to one side of the exhaust piston. One end of the second exhaust port 515 is connected to the reverse air port 512, the middle part is connected to the reverse fan blade 52, and the other end is connected to the outside of the drive component 51. The first exhaust port 514 is connected to the reverse fan blade 52. The first exhaust port 514 and the second exhaust port 515 are used to quickly discharge the gas that is stagnant in the reverse direction of the drive component 51.

[0058] In other words, the drive component 51 is provided with a forward rotation air hole 511 and a reverse rotation air hole 512. The forward rotation air hole 511 is connected to the forward rotation pipe 413, so that the air supply chamber 41 can pass gas into the drive component 51 through the forward rotation pipe 413. The gas enters the forward rotation chamber 513, which is equipped with a ball valve. The switch of the ball valve is connected to the riveting gun head. By pressing the riveting gun head, the ball valve can be opened, so that the gas can be blown through the forward rotation chamber 513 to the reverse rotation fan blade 52. The reverse rotation fan blade 52 converts the pressure energy of the gas into rotational mechanical energy, thereby causing the drive component 51 to rotate forward to drive the riveting gun to rivet. The gas after use is discharged through the first exhaust hole 514 connected to the forward rotation chamber 513.

[0059] Furthermore, the reverse air hole 512 is connected to the reverse pipe 412, allowing the gas output from the force control system 4 into the reverse pipe 412 to enter the drive member 51. The gas enters the second exhaust hole 515 through the reverse air hole 512, and the gas pushes the exhaust piston in the second exhaust hole 515 to move into the air guide pipe 516. The gas enters the chamber where the reverse fan blade 52 is located through the air guide pipe 516, and the reverse fan blade 52 converts the pressure energy of the gas into rotational mechanical energy. Since the outlet direction of the air guide pipe 516 is different from that of the forward rotation chamber 513, the drive member 51 reverses to drive the riveting gun to unrivet. After the gas in the reverse pipe 412 stops outputting, the exhaust reset spring pushes the exhaust piston to reset, so that the air guide pipe 516 is connected to the outside of the drive member 51. The used gas is quickly discharged through the first exhaust hole 514 and the second exhaust hole 515, so that the forward and reverse rotation of the drive member 51 alternates rapidly.

[0060] It should be noted that this application does not limit the specific size of the first exhaust hole 514, the second exhaust hole 515, and the air guide pipe 516. They can be reasonably selected according to the actual situation. Specifically, the diameter of the first exhaust hole 514, the second exhaust hole 515, and the air guide pipe 516 can be 5mm to 20mm, as long as it can achieve rapid exhaust of gas in the drive component 51.

[0061] like Figures 2 to 4 As shown, in this embodiment, the base assembly 1 includes an air regulating assembly 46. The air regulating assembly 46 includes an air regulating button disposed on one side of the base assembly 1 and an air regulating pipe 461 connecting the air supply chamber 41 and the drive assembly 5. The air regulating button is used to control the opening and closing of the air regulating pipe 461, and the air regulating pipe 461 is used to introduce gas into the drive assembly 5 to cause the rivet gun to reverse and reset.

[0062] Specifically, the air supply chamber 41 is connected to an air regulating pipe 461, which is connected to the drive assembly 5. An air regulating button is provided on the base assembly 1, which is connected to the air regulating pipe 461. The air regulating button can control the opening and closing of the air regulating pipe 461, so that the gas in the air supply chamber 41 is introduced into the drive assembly 5 through the air regulating pipe 461, causing the drive assembly 5 to reverse.

[0063] In other words, when the rivet gun malfunctions during use, if the user wants to remove the riveting parts from the rivet gun head, pressing the air adjustment button will cause the air supply chamber 41 to output gas to the drive assembly 5 through the air adjustment pipe 461, which will then drive the rivet gun to remove the riveting parts from the rivet gun head.

[0064] It should be noted that this application does not limit the specific structure of how the gas regulating pipe 461 is connected to the drive component 5. A reasonable choice can be made according to the actual situation. Specifically, the gas regulating pipe 461 can be a separate pipe connected to the drive component 5, or it can be connected in parallel to the reversing pipe 412, as long as it can realize the gas supplied by the gas supply chamber 41 into the drive component 5 and make the drive component 5 reverse.

[0065] In summary, this application provides a riveting gun with force control function. Gas is supplied from the air supply chamber 41 to the pressure regulating chamber 431. Part of the gas in the pressure regulating chamber 431 is supplied to the drive assembly 5 through the forward rotation pipe 413, causing the drive assembly 5 to control the forward rotation of the riveting gun and perform riveting. The other part is supplied to the riveting control assembly 42 and the riveting retraction control assembly 44 through the pressure regulating pipe 411. The gas pressure in the pressure regulating pipe 411 drives the riveting control rod 422 to move. The riveting control rod 422 moves within the pressure regulating chamber 431, thereby connecting the pressure regulating chamber 431 to the riveting cylinder 421. This allows the gas supplied by the air supply chamber 41 to enter the riveting cylinder 421, which in turn drives the riveting gun to perform riveting. During riveting, the gas entering the pressure regulating pipe 411 of the riveting unriveting control component 44 reaches a certain pressure after passing through the airflow reducer valve 432, which pushes the drive control rod 441 to move. Due to the high pressure at the drive control rod 441 in the pressure regulating chamber 431, the drive control rod 441 moves in the opening direction, causing the riveting control rod 422 to move in the closing direction. Ultimately, the pressure regulating chamber 431 is connected to the drive component 5, and the pressure regulating chamber 431 is connected to the riveting cylinder 421 and closed, allowing the gas supplied by the air supply chamber 41 to enter the drive component 5. This causes the drive component 5 to drive the riveting gun to reverse, thereby unriveting the riveted parts. After the riveting gun is unriveted, the elastic force generated by the compression of the second return spring 442 will push the drive control rod 441 to return to its original position.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
