Therefore, an automatic gripping device for assembly lines is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems of inconvenience in centering and clamping irregularly shaped or spherical objects and inconvenience in supporting the bottom surface of objects when clamping them, this utility model proposes an automatic gripping device for production lines.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The automatic gripping device for assembly line of this utility model includes a cylinder; a conical cylinder is fixedly connected to the bottom of the cylinder, a clamping assembly is slidably connected to the inner surface of the conical cylinder, a top plate is connected through the surface of the clamping assembly, a connecting block is fixedly connected to one side of the cylinder, a vertical plate is fixedly connected to one side of the connecting block, and a support assembly is rotatably connected to one side of the vertical plate.

[0014] The advantages of this utility model are:

[0015] 1. Through the structural design of the clamping assembly, this utility model enables the automatic gripping device to lower the entire clamp above the object via a telescopic rod. Then, servo motor A is connected to the power supply, causing transmission rod A to rotate the threaded rod and push the threaded cylinder downward. During the descent, the threaded cylinder drives the connecting plate to descend. As the connecting plate descends, the square block on the side retracts into the shrinking cylinder while compressing the limiting spring. Simultaneously, the slider slides along the inner surface of the conical cylinder towards the bottom, causing the four clamping blocks to move in the center while descending. By clamping the object in four directions, the automatic gripping device can clamp irregularly shaped or spherical objects in the center, thus improving the applicability of the automatic gripping device.

[0016] 2. Through the structural design of the support component, this utility model clamps the object and then connects the B servo motor to the power supply. This causes the B transmission rod to drive the long rod to rotate outward from the groove on one side of the vertical plate until the support block contacts the bottom surface of the clamped object. This allows the automatic gripping device to support the bottom surface of the object while gripping it, thus improving the gripping stability of the automatic gripping device.

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 scope of protection of the present utility model.

[0025] The clamping assembly 3 includes a slider 301 slidably connected to the inner surface of the conical cylinder 2. A connecting plate 302 is fixedly connected to one side of the slider 301.

A threaded rod 307 is threadedly connected to the inner surface of the threaded cylinder 306. The bottom of the threaded rod 307 is rotatably connected to the conical cylinder 2. A top plate 4 is connected through the top of the threaded rod 307. An A transmission rod 308 is fixedly connected to the top of the threaded rod 307.

[0026] The support assembly 7 includes a long rod 701 rotatably connected to one side of the vertical plate 6. A support block 702 is fixedly connected to the top edge of the long rod 701. A B transmission rod 703 is fixedly connected to one side of the long rod 701. One end of the B transmission rod 703 is splinedly connected to the output end of the B servo motor 704. The vertical plate 6 is connected through the surface of the B transmission rod 703.

[0027] During operation, thanks to the structural design of the clamping assembly 3, when using this automatic gripping device, the telescopic rod 12 drives the entire clamp to descend above the object. Then, the A servo motor 309 is connected to the power supply, causing the A transmission rod 308 to drive the threaded rod 307 to rotate, pushing the threaded cylinder 306 downwards. During descent, the threaded cylinder 306 drives the connecting plate 302 downwards. As the connecting plate 302 descends, the square blocks on its side retract into the contraction cylinder 305, compressing the limit spring 304. Simultaneously, the slider 301 slides against the inner surface of the conical cylinder 2 towards the bottom, causing the four clamping blocks 303 to descend... Simultaneously moving towards the center, the automatic gripping device clamps objects in four directions, enabling it to clamp irregularly shaped or spherical objects, thus improving its applicability. Through the structural design of the support component 7, after the object is clamped by the clamping component 3, the B servo motor 704 is connected to the power supply and energized, causing the B transmission rod 703 to drive the long rod 701 to rotate outward from the groove on one side of the vertical plate 6 until the support block 702 contacts the bottom surface of the clamped object. This allows the automatic gripping device to support the bottom surface of the object while clamping it, improving the gripping stability of the automatic gripping device.

[0028] Furthermore, a motor box 8 is fixedly connected to the surface of servo motor 309, and a top plate 4 is fixedly connected to the bottom of motor box 8;

[0031] During operation, the position of the clamp can be lowered or raised by the telescopic rod 12.

[0032] Furthermore, a sliding block 13 is fixedly connected to the top of the telescopic rod 12, and a slide rail 16 is slidably connected to the inner surface of the sliding block 13.

[0033] During operation, the automatic gripping device can move along the slide rail 16 by setting the sliding block 13 and the slide rail 16.

[0035] During operation, the B motor box 9 is configured to protect and support the B servo motor 704.

[0036] Furthermore, a block 14 is fixedly connected to the surface of the vertical plate 6, and a pressure sensor 15 is provided on one side of the block 14;

[0037] During operation, by setting up the block 14 and the pressure sensor 15, when the long rod 701 is retracted into the groove on the side of the vertical plate 6, the long rod 701 squeezes the pressure sensor 15, the pressure sensor 15 disconnects the power supply to the B servo motor 704, and the brake inside the B servo motor 704 fixes the long rod 701.

[0038] Working principle: When using this automatic gripping device, the telescopic rod 12 drives the entire clamp to descend above the object. Then, the A servo motor 309 is connected to the power supply and powered on, causing the A transmission rod 308 to drive the threaded rod 307 to rotate and push the threaded cylinder 306 to descend. During the descent, the threaded cylinder 306 drives the connecting plate 302 to descend. When the connecting plate 302 descends, the square block on the side retracts into the shrinking cylinder 305 while compressing the limiting spring 304. At the same time, the slider 301 slides against the inner surface of the conical cylinder 2 to the bottom, so that the four clamping blocks 303 move in the center to clamp the object while descending. After the object is clamped by the clamping assembly 3, the B servo motor 704 is connected to the power supply and powered on, causing the B transmission rod 703 to drive the long rod 701 to rotate outward from the groove on one side of the vertical plate 6 until the support block 702 contacts the bottom surface of the clamped object.
