The third cylinder is fixedly connected to the sliding plate through a second L-shaped mounting plate.

[0005] The material support mechanism is arranged diagonally along the mounting frame.

[0006] The outer side of the support block protrudes outward in an arc shape, and the pressure plate has a guide arc that matches the outer side of the support block.

[0007] A positioning rod is provided at the bottom of the support block.

[0008] The mounting frame is a square frame structure composed of four crossbeams. Adjacent crossbeams are connected by right-angle connecting plates, and a limiting block is provided on the outer side of each right-angle connecting plate.

[0009] A sealing ring guide block is provided at the traveling end of the pressure roller mounting plate.

[0010] This utility model has the following features and beneficial effects: 1.

Detailed Implementation

[0022] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0023] like Figure 1-7 As shown, a square sealing ring clamping mechanism includes a mounting frame 1, on which a cylindrical connector 11 for connecting a robotic arm is mounted. Serving as the foundation support of the entire device, the mounting frame 1 is a square frame structure composed of four crossbeams. Adjacent crossbeams are reinforced by right-angle connecting plates 13 to enhance overall rigidity and stability. Limiting blocks 44 are provided on the outer surface of the right-angle connecting plates 13 to prevent the pressing mechanism 4 from exceeding a predetermined range during sliding. The cylindrical connector 11 is located at the top or a suitable position of the mounting frame 1 for connection to an external robotic arm, facilitating the movement and positioning of the entire device.

[0024] Four material support mechanisms 2 are arranged in an array at the lower part of the mounting frame 1, along the diagonal of the mounting frame 1. Each material support mechanism 2 includes a material support block 21, a mounting plate 22, and a first cylinder 23. The material support block 21 is vertically mounted on the mounting plate 22, with its outer side convex in an arc shape to accommodate sealing rings of different shapes. A positioning rod 211 is provided at the bottom of the material support block 21 for precise positioning of the sealing ring to be assembled. The mounting plate 22 is connected to the first cylinder 23, which is fixedly mounted to the mounting frame 1 via a first L-shaped mounting plate 24. The mounting plate 22 is fixed to one end of the first cylinder 23 and connected to the mounting frame 1 via the first L-shaped mounting plate 24. The first cylinder 23 drives the material support block 21 to move up and down, thus completing the material support action.

[0025] The end of the supporting mechanism 2 is provided with a feeding mechanism 3, which includes a pressure plate 31 and a second cylinder 32. The pressure plate 31 is mounted on the end of the mounting plate 22 in a vertical direction, fitting against the outer side of the supporting block 21. The second cylinder 32 is connected to the pressure plate 31 and is used to drive the movement of the pressure plate 31 to ensure that the sealing ring is correctly placed on the supporting block 21. The pressure plate 31 is mounted on the end of the mounting plate 22 in a vertical direction, fitting against the outer side of the supporting block 21, and has a guide arc 311 that matches the outer side of the supporting block 21 to guide and fix the sealing ring.

[0026] The mounting frame 1 is also equipped with a pressing mechanism 4, which includes a sliding plate 41 and a pressure roller component 42 mounted on the mounting frame 1. Figure 4 As shown, the slide plate 41 is installed in a groove 12 opened on the lower end face of the mounting frame 1, and can slide within the groove 12. The pressure roller component 42 includes a pressure roller 421, a pressure roller mounting plate 422, and a third cylinder 423. The third cylinder 423 is fixedly connected to the slide plate 41 via a second L-shaped mounting plate 43. The third cylinder 423 is fixedly connected to the slide plate 41 via the second L-shaped mounting plate 43 and is used to drive the pressure roller component 42 to slide along the slide plate 41. The pressure roller mounting plate 422 fixes the pressure roller 421, and the pressure roller 421 is used to press the sealing ring into a preset position.

[0027] Furthermore, such as Figure 8 , 9 As shown, the pressure roller mounting plate 422 fixes the pressure roller 421, and a sealing ring guide block 424 is provided at its traveling end to help the sealing ring smoothly enter the installation position. Two or three pressure rollers can be provided as needed.

[0028] Working principle: 1. Preparation stage: The robotic arm moves the entire gripping mechanism to the sealing ring picking station through the cylindrical connector 11.

[0029] 2. Supporting stage: The first cylinder 23 drives the supporting block 21 to move outward, using the arc-shaped outer side of the supporting block 21 to open the sealing ring.

[0030] 3. Loading stage: The robotic arm drives the gripping and pressing mechanism to move to the appropriate position of the front sealing ring in the installation station 5, so that the positioning rod 211 on the support block 21 is accurately aligned with the inner side of the sealing ring installation groove 51 of the sealing ring to be assembled.

[0031] 4. Pressing stage: The second cylinder 32 drives the pressure plate 31 to move, and the third cylinder 423 drives the slide plate 41 to move the pressure roller component 42. The pressure roller 421 presses the sealing ring into the preset position to complete the assembly.

[0032] 5. Reset phase: Under the action of the cylinder, each component returns to its initial state, ready for the next cycle.

[0033] This structural design not only simplifies the assembly process of the square sealing ring, but also improves assembly accuracy and efficiency, and reduces the error rate caused by human factors.
