Description

Technical Field

[0001] This utility model relates to the field of composite fixture technology, specifically to a composite fixture for industrial robots. Background Technology

[0002] Complete sets of industrial robot automated production line equipment have become the mainstream of automation equipment and are widely used in industries such as casting, electronics, and machinery. During the use of these robots, they need to have clamps to clamp and fix the workpieces, so as to facilitate the operation and movement of the workpieces.

[0003] Industrial robot fixtures are generally only applicable to one type of work or one type of workpiece. Each time a functional module is changed, the fixture must be replaced. They are dedicated to specific machines and have good adaptability, but they cannot achieve multi-purpose use, which is not conducive to cost reduction and work efficiency improvement. Therefore, we propose an industrial robot composite fixture. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an industrial robot composite clamp that can adjust the size and angle of the clamping mechanism through hydraulic push rods and auxiliary mechanisms to clamp workpieces of various specifications and models; it also has a vacuum mechanism to suction and clamp the top of the workpiece, with good fixing effect and high practicality, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial robot composite gripper includes a gripper body;

[0006] The fixture body has fixed blocks rotatably mounted on the left and right ends of the upper side. The fixed blocks are rotatably connected to the fixture body through an auxiliary mechanism. A clamping mechanism is provided inside the fixed blocks, and a vacuum mechanism is provided in the middle of the fixture body.

[0007] The clamping mechanism includes a hydraulic push rod and two telescopic rods. A fixed block is fixedly connected to the hydraulic push rod and two telescopic rods. The telescopic rods are located on the front and rear sides of the hydraulic push rod. A clamping block is fixedly connected to the inner side of the hydraulic push rod and the telescopic rods. An anti-slip plate is fixedly connected to the inner side of the clamping block. The input end of the hydraulic push rod is electrically connected to the output end of an external controller. The external controller controls the hydraulic push rod to push the clamping block. The telescopic rod extends as the hydraulic push rod extends, causing the anti-slip plate to clamp the workpiece. The size and distance between the clamping blocks can be adjusted by the hydraulic push rod, which is convenient for clamping workpieces of different sizes.

[0008] Furthermore, the auxiliary mechanism includes a connecting plate, with the front and rear sides of the clamp body fixedly connected to the connecting plate. A rotating shaft is fixedly installed inside the fixing block. One end of the rotating shaft passes through the connecting plate and is fixedly connected to the output shaft of the drive motor. The other end of the rotating shaft passes through the connecting plate on the opposite side and is rotatably connected to the fastening bearing. The input end of the drive motor is electrically connected to the output end of an external controller. The external controller starts the drive motor, causing the rotating shaft to rotate at a certain angle. The rotation of the rotating shaft causes the fixing block to rotate at a certain angle. When the drive motor stops, the fastening bearing and the rotating shaft self-lock, and the fixing block stops rotating, thereby adjusting the angle of the clamping block to clamp workpieces of different shapes.

[0009] Furthermore, a square groove is provided in the middle of the fixture body, and a slider is slidably provided in the square groove. The lower side of the slider is fixedly connected to the mounting plate, and the upper side of the slider is fixedly connected to the support plate. The slider can slide vertically in the square groove, which plays a buffering role.

[0010] Furthermore, two damping rods are fixedly connected to the lower side of the support plate. The lower side of the damping rods is fixedly connected to the fixture body, and a spring is sleeved on the outer side of the damping rods to buffer the vacuum mechanism's suction on the workpiece and improve the service life of the device.

[0011] Furthermore, the vacuum mechanism includes a suction cup, which is fixedly installed inside the support plate. The lower side of the suction cup is connected to the air inlet of the suction pipe, and the lower air outlet of the suction pipe is connected to the air inlet of the suction pump. The suction pump is installed inside the mounting plate, and a rubber pad is fixedly installed on the upper side of the fixture body. The input end of the suction pump is electrically connected to the output end of an external controller. After the external controller starts the suction pump, the workpiece is clamped and fixed through the suction pipe and the suction cup, which improves the fixing effect and has high practicality.

[0012] Furthermore, a mounting frame is fixedly connected to the lower side of the fixture body, and two mounting slots are provided on the upper side of the mounting frame for fixed connection with the robotic arm of the industrial robot.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This industrial robot composite gripper has the following advantages:

[0014] 1. The hydraulic push rod is controlled by an external controller to push the clamping block. The telescopic rod extends as the hydraulic push rod extends, which drives the anti-slip plate to clamp the workpiece. The size and distance between the clamping blocks can be adjusted by the hydraulic push rod, which is convenient for clamping workpieces of different sizes.

[0015] 2. The drive motor is started by the external controller, which drives the rotating shaft to rotate at a certain angle. The rotation of the rotating shaft drives the fixed block to rotate at a certain angle. When the drive motor stops, the fastening bearing and the rotating shaft self-lock, and the fixed block stops rotating. This is used to adjust the angle of the clamping block so as to clamp workpieces of different shapes.

[0016] 3. The air pump is started by an external controller, and the workpiece is clamped and fixed by the air suction pipe and suction cup, which improves the fixing effect and makes it highly practical. Attached Figure Description

The size distance between the clamping blocks 43 can be adjusted by the hydraulic push rod 41, which is convenient for clamping workpieces of different sizes.

[0025] The auxiliary mechanism 3 includes a connecting plate 31. The front and rear sides of the fixture body 1 are fixedly connected to the connecting plate 31. A rotating shaft 33 is fixedly installed inside the fixing block 2.

The input end of the drive motor 32 is electrically connected to the output end of an external controller. The external controller starts the drive motor 32, causing the rotating shaft 33 to rotate at a certain angle. The rotation of the rotating shaft 33 causes the fixing block 2 to rotate at a certain angle. When the drive motor 32 stops, the fastening bearing 34 and the rotating shaft 33 self-lock, and the fixing block 2 stops rotating. This is used to adjust the angle of the clamping block 43 so as to clamp workpieces of different shapes. A square groove 5 is provided in the middle of the fixture body 1.

A spring 10 is sleeved on the outside of the damping rods 9 to buffer the vacuum mechanism 11 from clamping the workpiece and improve the service life of the device. The vacuum mechanism 11 includes a suction cup 111. The suction cup 111 is fixedly installed inside the support plate 8. The lower side of the suction cup 111 is connected to the air inlet of the air extraction pipe 112. The lower air outlet of the air extraction pipe 112 is connected to the air inlet of the air pump 113. The air pump 113 is installed inside the mounting plate 7. A rubber pad 12 is fixedly installed on the upper side of the fixture body 1. The input end of the air pump 113 is electrically connected to the output end of the external controller.

After the external controller starts the vacuum pump 113, the workpiece is clamped and fixed through the vacuum pipe 112 and the suction cup 111, improving the fixing effect and increasing practicality. The slider 6 can slide vertically within the square slot 5, acting as a buffer. The damping rod 9 and spring 10 are used to buffer the vacuum mechanism 11's suction of the workpiece, improving the service life of the device. After clamping and fixing, the external controller controls the... The hydraulic push rod 41 pushes the clamping block 43, and the telescopic rod 42 extends as the hydraulic push rod 41 extends, driving the anti-slip plate 44 to clamp the workpiece. The size and distance between the clamping blocks 43 can be adjusted by the hydraulic push rod 41 to facilitate clamping workpieces of different sizes. The external controller starts the drive motor 32, which drives the rotating shaft 33 to rotate at a certain angle.

When the drive motor 32 stops, the fastening bearing 34 and the rotating shaft 33 self-lock, and the fixed block 2 stops rotating. This is used to adjust the angle of the clamping block 43 so as to clamp workpieces of different shapes.
