Description

Technical Field

[0001] This utility model relates to a clamping device, specifically a clamping device for manufacturing multi-size industrial robots, belonging to the field of industrial robot technology. Background Technology

[0002] An industrial robot is a multi-jointed manipulator or multi-degree-of-freedom machine device designed for industrial applications. It can automatically perform tasks and achieve various functions through its own power and control capabilities. It typically consists of a mechanical body, a control system, a drive system, and sensors.

[0003] A search revealed a Chinese patent (CN218313617U) disclosing a clamping device for industrial robot manufacturing. The device includes a processing table and two sets of clamping mechanisms mirror-mounted on top of the processing table. Each clamping mechanism comprises a movable frame, multiple sets of pulleys mounted on the bottom of the movable frame, a bearing seat fixed to the top of the lower end of the movable frame, a support shaft rotatably connected to the inner ring of the bearing seat, and a turntable fixed to the top of the support shaft. This clamping device for industrial robot manufacturing uses slots and blocks to assemble and fix the clamps within mounting notches. Rotating the turntable allows the corresponding clamps to be rotated to the position where the parts need to be clamped. A drive motor drives a rack and pinion to move horizontally synchronously with the movable frame, thereby clamping and fixing the parts using the clamps on the surfaces of the two turntables. This clamping device for industrial robot manufacturing offers high clamping adjustability, effectively improving its applicability for clamping different parts. It also boasts high clamping stability, simple adjustment, and ease of use.

[0004] While the above solutions offer high adjustability, high clamping stability, and simple adjustment, the clamping devices in the aforementioned patents are difficult to change the position of the parts. When manufacturing industrial robot parts, depending on actual needs, different positions of the parts often require grinding or other processes. However, once the parts are fixed in the aforementioned patents, they remain stationary, requiring readjustment of the clamping orientation, which is inconvenient for operators. Therefore, we provide a clamping device for manufacturing multi-size industrial robots to solve the above problems. Utility Model Content

[0024] This utility model provides a clamping device for manufacturing multi-size industrial robots.

[0025] Please see Figure 1 The system includes a main support base 1, a hydraulic cylinder 2 fixedly connected to one side of the main support base 1, and a linkage plate 3 fixedly connected to one end of the hydraulic cylinder 2. The purpose of setting the hydraulic cylinder 2 is to provide sufficient power support for the translation of the linkage plate 3. The hydraulic cylinder 2 is a known technology and will not be described in detail in this application.

[0026] Please see Figure 1 , Figure 2 and Figure 3 A U-shaped frame 4 is fixedly connected to one side of the linkage plate 3. The linkage plate 3 and the U-shaped frame 4 maintain a linkage effect and can push the two U-shaped frames 4 to move synchronously. A force-applying rod 5 is rotatably connected to the inner wall of the U-shaped frame 4. The force-applying rod 5 will follow the movement of the U-shaped frame 4, and the U-shaped frame 4 will support the force-applying rod 5 and apply a position control effect to ensure that the force-applying rod 5 can rotate in place. The force-applying rod 5 is slidably connected in the guide groove 7 opened in the irregular linkage plate 6. The force-applying rod 5 can rotate smoothly in the guide groove 7 and drive the irregular linkage plate 6 to move through displacement.

[0027] Please see Figure 1 , Figure 2 and Figure 5 There are two irregularly shaped linkage plates 6, which are fixedly connected to the bottom of the protective shell 12. The two irregularly shaped linkage plates 6 can effectively support the protective shell 12, thereby ensuring the stability of the protective shell 12. A unidirectional DC motor 13 is fixedly connected to one side of the protective shell 12. The output shaft of the unidirectional DC motor 13 is fixedly connected to a bidirectional lead screw 14. The purpose of setting the unidirectional DC motor 13 is to effectively provide sufficient power support for the rotation of the bidirectional lead screw 14. The unidirectional DC motor 13 is a known technology and will not be described in detail.

[0028] Please see Figure 4 and Figure 5 The threads at both ends of the bidirectional lead screw 14 are opposite. The outer circumferential surface of the bidirectional lead screw 14 is threadedly connected to the inner wall of the linkage slider 15. There are two linkage sliders 15. The design of the bidirectional lead screw 14 allows the two linkage sliders 15 to move synchronously, and the two linkage sliders 15 move in opposite directions.

[0029] Please see Figure 1 , Figure 4 and Figure 5 Two linkage sliders 15 are slidably connected inside the protective shell 12 via a control rail 17. The purpose of setting the control rail 17 is to ensure the stability of the two linkage sliders 15, so that the two linkage sliders 15 can only move in the horizontal direction. A part clamping plate 16 is fixedly connected to the top of the linkage slider 15. The linkage slider 15 and the part clamping plate 16 maintain a linkage effect. The part clamping plate 16 has anti-slip texture. There are two part clamping plates 16 in total. The two part clamping plates 16 can clamp the part, thereby ensuring the stability of the part and preventing the part from falling off or shaking.

[0030] Please see Figure 3 and Figure 5The outer circumferential surface of the bidirectional lead screw 14 is rotatably connected to the inner wall of the protective shell 12. The protective shell 12 provides auxiliary support for the bidirectional lead screw 14, thereby ensuring that the bidirectional lead screw 14 can rotate in place without falling off or tilting. The inner wall of the irregular linkage plate 6 is rotatably connected to the outer circumferential surface of the support positioning rod 8. The two ends of the support positioning rod 8 are fixedly connected to the inner wall of the U-shaped frame 9. The purpose of setting the support positioning rod 8 is to make the irregular linkage plate 6 rotate about the support positioning rod 8 as the axis.

[0031] Please see Figure 1 and Figure 2 The U-shaped frame 29 is fixedly connected to buffer 10 and buffer 21 on both sides respectively. The bottom of the U-shaped frame 29 is fixedly connected to the main support base 1. The buffer 10 and buffer 21 can buffer the inertia of the irregular linkage plate 6 after it moves, thereby ensuring the stability of the irregular linkage plate 6 and other components. Buffer 10 and buffer 21 are both existing known technologies and will not be described in detail in this application.

[0032] Working principle: In use, the robot part is placed on the protective shell 12, and the unidirectional DC motor 13 is started, driving the bidirectional lead screw 14 to rotate in place inside the protective shell 12. At this time, because the linkage slider 15 is restricted by the control track 17, the linkage slider 15 can only move in translation, so the bidirectional lead screw 14 can drive the linkage slider 15 to move the part clamping plate 16. Due to the opposite thread design at both ends of the bidirectional lead screw 14, the two linkage sliders 15 move in opposite directions, driving the two part clamping plates 16 to clamp the robot part, ensuring the robot... The stability of the robot parts facilitates subsequent operations. According to actual needs, the hydraulic cylinder 2 can be activated to work, and the U-shaped frame 4 can be moved by the linkage plate 3. At this time, because the irregular linkage plate 6 rotates around the support positioning rod 8, when the U-shaped frame 4 drives the force-applying rod 5 to move, the force-applying rod 5 will slide in the guide groove 7 and drive the irregular linkage plate 6 to move, so that the orientation of the robot parts on the protective shell 12 changes, achieving the purpose of freely adjusting the tilt angle, preventing the phenomenon of bending over during operation, and thus making it more convenient for workers to perform operations.
