Description

Technical Field

[0001] This utility model relates to the field of rivet gun technology, and in particular to a rivet gun with automatically controllable force. Background Technology

[0002] A rivet gun is a tool used to fasten rivets to workpieces and is widely used in industries such as machinery manufacturing, construction, and automobiles. Traditional rivet guns usually require manual operation by turning an adjustment knob to adjust the position of the pressure regulating valve core, thereby adjusting the pulling force. This is not only cumbersome and inefficient, but also makes it difficult to accurately control the pulling force, which can easily lead to problems such as insecure rivet fastening or damage to the workpiece. Summary of the Invention

[0003] According to an embodiment of the present invention, an automatically controllable force rivet gun is provided, comprising a gun body, a pressure regulating valve disposed on the gun body, and further comprising:

[0004] The drive mechanism is connected to the gun body, and its output end is connected to the valve core of the pressure regulating valve. It can drive the valve core to move linearly to adjust the pulling force of the rivet gun.

[0005] Furthermore, the drive mechanism is one of a cylinder, an electric cylinder, or a linear motor.

[0006] Furthermore, it also includes: a drive plate, one end of which is connected to the output end of the drive mechanism, and the other end is connected to the valve core. The drive mechanism drives the valve core to move by driving the drive plate.

[0007] Furthermore, the driver board is L-shaped.

[0008] Furthermore, it also includes: a guide plate, which is slidably connected to the drive mechanism and fixedly connected to the drive plate.

[0009] Furthermore, the guide plate is L-shaped.

[0010] The rivet gun with automatic force control according to the present invention achieves automatic adjustment of the rivet gun's pulling force by driving the valve core of the pressure regulating valve to move linearly through a drive mechanism, eliminating the need for manual operation and improving operational efficiency and convenience. The drive mechanism can be selected from cylinders, electric cylinders, or linear motors, offering multiple drive methods to meet different usage needs. The design of the drive plate and guide plate makes the connection between the drive mechanism and the valve core more stable and reliable, while the guide plate ensures the smoothness and accuracy of the drive mechanism's movement, thereby improving the accuracy of the pulling force adjustment. The L-shaped drive plate and guide plate make reasonable use of space, making the entire rivet gun structure more compact, smaller in size, and easier to carry and use.

[0011] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0013] Figure 2 This is a top view schematic diagram according to an embodiment of the present utility model. Detailed Implementation

[0014] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0015] First, combine Figures 1-2 The present invention describes an automatically controllable force rivet gun according to an embodiment of the present invention, which is used in the field of rivet technology and has a wide range of applications.

[0016] like Figures 1-2 As shown, the rivet gun with automatic force control according to this utility model embodiment includes a gun body 1, a pressure regulating valve provided on the gun body 1, and further includes:

[0017] Drive mechanism 2 is connected to gun body 1. Its output end is connected to valve core 3 of pressure regulating valve. It can drive valve core 3 to move linearly to adjust the pulling force of rivet gun.

[0018] Furthermore, in this embodiment, the drive mechanism 2 is one of a pneumatic cylinder, an electric cylinder, or a linear motor. A pneumatic cylinder is suitable for scenarios with sufficient air supply and has low cost; an electric cylinder has high-precision position control characteristics and is suitable for precision riveting; a linear motor has a fast response speed and meets the requirements of high-speed dynamic adjustment.

[0019] Furthermore, such as Figures 1-2 As shown, in this embodiment, it also includes: a drive plate 4, one end of which is connected to the output end of the drive mechanism 2, and the other end is connected to the valve core 3. The drive mechanism 2 drives the valve core 3 to move by driving the drive plate 4.

[0020] Furthermore, such as Figures 1-2 As shown, in this embodiment, the drive plate 4 is L-shaped. The L-shaped design can optimize the spatial layout and avoid interference with other components of the gun body 1.

[0021] Furthermore, such as Figures 1-2 As shown, in this embodiment, it also includes: a guide plate 5, which is slidably connected to the drive mechanism 2 and fixedly connected to the drive plate 4, providing linear guidance for the movement of the drive plate 4, eliminating the influence of lateral force, and ensuring the movement accuracy of the valve core 3.

[0022] Furthermore, such as Figures 1-2 As shown, in this embodiment, the guide plate 5 is L-shaped. The L-shaped design can optimize the spatial layout and avoid interference with other components of the gun body 1.

[0023] Working principle: When the rivet gun tension needs to be adjusted, the control system sends a command to the drive mechanism 2. The output end of the drive mechanism 2 begins to move linearly, driving the drive plate 4 to move. Since the drive plate 4 is connected to the valve core 3, it drives the valve core 3 to move linearly within the pressure regulating valve, changing the opening size of the pressure regulating valve, thereby adjusting the rivet gun tension. The guide plate 5 plays a guiding role during the movement of the drive mechanism 2, ensuring that the output end of the drive mechanism 2 moves in a linear direction, improving the movement accuracy, and enabling the valve core 3 to accurately adjust the tension.

[0024] Above, refer to Figures 1-2 This invention describes an automatically force-controlled rivet gun according to an embodiment of the present invention. By setting a drive mechanism 2 to drive the valve core 3 of the pressure regulating valve to move linearly, the rivet gun's tension is automatically adjusted, eliminating the need for manual operation and improving operational efficiency and convenience. The drive mechanism 2 can be selected from cylinders, electric cylinders, or linear motors, offering multiple drive methods to meet different usage needs. The drive plate 4 and guide plate 5 make the connection between the drive mechanism 2 and the valve core 3 more stable and reliable. The guide plate 5 ensures the smoothness and accuracy of the drive mechanism 2's movement, thereby improving the accuracy of tension adjustment. The L-shaped drive plate 4 and guide plate 5 make reasonable use of space, making the entire rivet gun structure more compact, smaller in size, and easier to carry and use.
