Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a slanted arm robotic arm swing device. Background Technology

[0002] In the process of industrial production automation, robotic arms play a crucial role, significantly improving production efficiency, reducing labor costs, and ensuring product quality. As a common type, the slant-arm robotic arm is widely used in many production scenarios, such as injection molding, stamping, and material handling.

[0003] However, some existing slant arm robots are prone to inaccurate swinging during operation, which can adversely affect production precision, thereby reducing product quality. It may also cause the device to generate significant vibration and noise during operation, affecting the working environment, accelerating wear and tear, and shortening its service life. In addition, the stopping structure of some swing arm devices is not reliable enough. When it is necessary to stop the swing arm movement, it cannot brake in a timely and effective manner, which can easily lead to problems such as tooth breakage, affecting the normal operation of the device and even potentially causing safety accidents.

[0004] Therefore, it is necessary to modify it by setting a stabilizing mechanism to reinforce and stabilize the swing position of the inclined plate robot, thereby improving its stability during swing. A stop mechanism is also needed to effectively brake the robot when it stops swinging, preventing it from shaking or losing teeth when the arm stops, which would affect its use and improve the robot's safety and accuracy.

This device features a stabilizing mechanism to reinforce and stabilize the swing position of the slant arm manipulator, improving its stability during swing. A stopping mechanism effectively brakes the swing arm when it stops, preventing the manipulator from shaking or losing teeth when the swing arm stops, thus improving its usability. This design improves the safety and accuracy of the manipulator and solves the problems of inaccurate swinging in some slant arm manipulators, and the unreliable stopping structure of some swing arm devices, which cannot brake in a timely and effective manner when the swing arm needs to be stopped, easily leading to tooth loss and other phenomena that affect the normal operation of the device and may even cause safety accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slanted arm manipulator swing arm device, comprising a base, a rotating disk fixedly connected to the top of the base, a control box fixedly connected to the top of the rotating disk, a drive box fixedly connected to the top of the control box, an arm structure fixedly connected to the output end of the drive box, an annular stop plate fixedly connected to the right side of the arm structure, stabilizing rods fixedly connected to both the front and rear sides of the left side of the drive box, the left end of the stabilizing rods slidably connected to the right side of the annular stop plate, an upper pressure rod provided at the top of the drive box, a lower pressure frame provided below the drive box, an arc-shaped stop plate for cooperating with the annular stop plate fixedly connected to the left end of both the upper pressure rod and the lower pressure frame, a triangular plate fixedly connected to the right end of the upper pressure rod and the lower pressure frame, a stop cylinder fixedly connected to the right side of the drive box, the output end of the stop cylinder fixedly connected to the left side of the triangular plate, and the stop cylinder being in an extended state.

[0007] In a preferred embodiment of this invention, an annular slide rail is fixedly connected to the right side of the annular stop disc, and a slider is fixedly connected to the left end of the stabilizer rod. The surface of the slider is slidably connected to the inner wall of the annular slide rail.

[0008] As a preferred embodiment of this invention, a stabilizing ring is slidably connected to the surface of the upper pressure rod, and the bottom of the stabilizing ring is fixedly connected to the top of the drive box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a rotating disk fixedly connected to the top of the base. A control box, a drive box, and an arm structure are sequentially connected to the rotating disk. This layered, fixed connection design ensures a stable basic structure for the entire inclined arm manipulator, enabling it to withstand certain external forces and vibrations during operation, thus guaranteeing the stability of the device. The output end of the drive box is connected to the arm structure, enabling the arm structure to swing and providing power support for the manipulator's work. The control box controls the operation of the drive box, ensuring the arm structure swings according to preset programs and parameters, improving the automation level and working accuracy of the device. The arm structure is a mature existing technology, so its working principle will not be described in detail. An effective stopping mechanism is constructed by incorporating components such as a ring-shaped stop plate, a stabilizing rod, an upper pressure rod, a lower pressure frame, an arc-shaped stop plate, a triangular plate, and a stop cylinder. When the stop cylinder retracts, it moves the triangular plate to the left, causing the arc-shaped stop plate on the upper pressure rod and lower pressure frame to engage with the ring-shaped stop plate, thus braking the swing arm device. Simultaneously, the stabilizing rod effectively supports the arm structure. This achieves the goal of reinforcing and stabilizing the swing position of the inclined plate manipulator through a stabilizing mechanism, improving stability during swing, and effectively braking when the swing arm stops, preventing the manipulator from shaking or losing teeth when the swing arm stops, which would affect its use, thereby improving the safety and accuracy of the manipulator.

By using a combination of annular slide rail and slider, this utility model makes the sliding of the stabilizer bar on the annular stop plate smoother, and also enhances the stability of the arm structure during the swinging process; the combination of slider and annular slide rail can limit the radial sway of the arm structure, reduce the deviation during the swinging process, and improve the motion accuracy of the robot.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a slanted arm manipulator swing arm device, including a base 1, a rotating disk 2 fixedly connected to the top of the base 1, a control box 3 fixedly connected to the top of the rotating disk 2, a drive box 4 fixedly connected to the top of the control box 3, an arm structure 5 fixedly connected to the output end of the drive box 4, an annular stop plate 6 fixedly connected to the right side of the arm structure 5, stabilizing rods 7 fixedly connected to the front and rear sides of the left side of the drive box 4, the left end of the stabilizing rod 7 being slidably connected to the right side of the annular stop plate 6, an upper pressure rod 8 provided at the top of the drive box 4, a lower pressure frame 9 provided below the drive box 4, an arc-shaped stop plate 10 for use with the annular stop plate 6 fixedly connected to the left end of both the upper pressure rod 8 and the lower pressure frame 9, a triangular plate 11 fixedly connected to the right end of the upper pressure rod 8 and the lower pressure frame 9, and a stop cylinder 12 fixedly connected to the right side of the drive box 4, the output end of the stop cylinder 12 being fixedly connected to the left side of the triangular plate 11, and the stop cylinder 12 being in an extended state.

[0022] refer to Figure 4 An annular slide rail 13 is fixedly connected to the right side of the annular stop plate 6, and a slider 14 is fixedly connected to the left end of the stabilizer rod 7. The surface of the slider 14 is slidably connected to the inner wall of the annular slide rail 13.

[0023] As a technical optimization of this utility model, by setting the cooperation of the annular slide rail 13 and the slider 14, the sliding of the stabilizer 7 on the annular stop plate 6 is smoother, and the stability of the arm structure 5 during the swing process is also enhanced; the cooperation between the slider 14 and the annular slide rail 13 can limit the radial sway of the arm structure 5, reduce the deviation during the swing process, and improve the motion accuracy of the robot.

[0024] refer to Figure 1A stabilizing ring 15 is slidably connected to the surface of the upper pressure rod 8, and the bottom of the stabilizing ring 15 is fixedly connected to the top of the drive box 4.

[0025] As a technical optimization of this utility model, by setting a stabilizing ring 15, the movement of the upper pressure rod 8 can be guided and constrained, preventing the upper pressure rod 8 from deviating or shaking during the movement, ensuring that the arc-shaped stop plate 10 can accurately cooperate with the annular stop disc 6, and improving the reliability of the stop mechanism.

[0026] refer to Figure 2 T-shaped blocks 16 are fixedly connected to the front and rear sides of the bottom of the drive box 4. T-shaped grooves 17 that cooperate with the T-shaped blocks 16 are opened on the front and rear sides of the top of the lower pressure frame 9. The surface of the T-shaped blocks 16 is slidably connected to the inner wall of the T-shaped grooves 17.

[0027] As a technical optimization of this utility model, by using the T-shaped block 16 and the T-shaped groove 17 together, when the lower pressure frame 9 moves, the T-shaped block 16 slides inside the T-shaped groove 17, making the lower pressure frame 9 more stable and smooth during the movement, and able to accurately follow the movement of the upper pressure rod 8, ensuring the effective cooperation between the arc-shaped stop plate 10 and the annular stop disc 6, and further improving the performance of the stop mechanism.

[0028] refer to Figure 1 A rubber plate 18 is fixedly connected to the bottom of the base 1, and mounting feet 19 are fixedly connected to all four sides of the rubber plate 18. Mounting holes are provided on the surface of the mounting feet 19.

[0029] As a technical optimization of this utility model, by setting the rubber plate 18 and the mounting feet 19 together, the rubber plate 18 has a certain elasticity, which can play a role in shock absorption, reduce the impact of vibration generated by the device during operation on the surrounding environment, and at the same time reduce the wear of the device itself and increase the friction between the device and the placement surface. The setting of the mounting feet 19 and the mounting holes facilitates the installation and fixing of the device, ensures that the device will not be displaced during operation, and improves the overall stability of the device.

[0030] refer to Figure 4 The right side of the annular stop plate 6 is fixedly connected to a first anti-slip pad 20, and the left side of the arc-shaped stop plate 10 is fixedly connected to a second anti-slip pad 21. The surfaces of the first anti-slip pad 20 and the second anti-slip pad 21 are both provided with anti-slip textures.

[0031] As a technical optimization of this utility model, by setting the first anti-slip pad 20 and the second anti-slip pad 21 in combination, the friction between the annular stop plate 6 and the arc-shaped stop piece 10 can be increased. When stopping, it can more effectively prevent the swing of the arm structure 5, improve the braking effect of the stop mechanism, and further avoid the situation of the robot arm shaking and dislodging when stopping the swing arm, thus ensuring the normal operation and safe use of the device.

[0032] The working principle and usage process of this utility model are as follows: When in use, the drive box 4 serves as the power source, and its output end is connected to the arm structure 5. The control box 3 receives external commands or controls the drive box 4 according to a preset program. The drive box 4 converts electrical energy and other energy into mechanical energy, driving the arm structure 5 to swing and realize the working action of the robot. The rotating disk 2 can rotate on the base 1, providing a certain degree of rotational freedom for the arm structure 5 and further expanding the working range of the robot. When it is necessary to stop the swinging action, the control box 3 issues a command to retract the stop cylinder 12, which drives the triangular plate 11 to move to the left. The triangular plate 11 drives the upper pressure rod 8 and the lower pressure frame 9 to move, so that the arc-shaped stop plate 10 at the left end of the upper pressure rod 8 and the lower pressure frame 9 fits tightly with the annular stop plate 6. Since the annular stop plate 6 is fixedly connected to the arm structure 5, the friction between the arc-shaped stop plate 10 and the annular stop plate 6 prevents the rotation of the annular stop plate 6, thereby braking the arm structure 5 and avoiding the robot from shaking or losing teeth when stopping the swinging action. At the same time, during the swinging process of the arm structure 5, the stabilizing rod 7 plays a supporting and guiding role, reducing the radial sway of the arm structure 5 and enhancing the stability of the swing.
