Description

Technical Field

[0002] Due to production process reasons in the production industry, some materials need to be flipped by 180° during the assembly process. Most of the existing technologies use robots or servo mechanisms for electric drive flipping. Among them, the six-axis collaborative robot can achieve complex movements, including flipping, through its flexible joint design.

[0003] When the six-axis collaborative robot performs a flipping movement, its mechanical structure may experience extreme load distributions, which may lead to structural deformation or damage. For example, the joints of the robot may encounter singular points at certain specific positions, which limit the movement range of the joints and may cause the joints to suddenly flip or get stuck, affecting the stability and safety of the robot.

[0004] To sum up, the existing flipping equipment has high costs, and the equipment also has higher potential safety hazards. For this reason, we propose a clamping and flipping mechanism. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figure 1 shown, a clamping and turning mechanism includes a turning mechanism 1, and the turning mechanism 1 is installed on the conveyor line body 3, and the conveyor line body 3 is used for conveying the material 2; as Figure 2 shown, the turning mechanism 1 includes a main body lifting mechanism 4 and a clamping and rotating mechanism 5.

[0033] As Figure 3 shown, the main body lifting mechanism 4 includes a main body bracket 41, floor feet 42, a lifting cylinder 43, a floating joint 44, a floating joint mounting plate 45, a slide rail 46, a slide block 47, a lifting frame 48, a reinforcing rib 1 49, a reinforcing rib 2 410, and a clamping and rotating mechanism mounting plate 411.

[0034] The main body bracket 41 is placed on the ground through the floor feet 42, and the height of the bracket can be finely adjusted through the floor feet 42. The slide rail 46 is fixed on the main body bracket 41, and the lifting frame 48 is installed on the slide block 47, so that the lifting frame 48 can slide within the range of the slide rail 46.

[0035] The reinforcing rib 1 49 is installed at the upper two corners of the lifting frame 48 by screws to improve the overall rigidity. The clamping and rotating mechanism mounting plate 411 is installed at the bottom of the lifting frame 48 by bolts, and the fixing mounting plate is increased by using the reinforcing rib 2 410.

[0036] The lifting cylinder 43 is fixed to the uppermost end of the main bracket 41 through the lifting cylinder mounting plate 412, and is connected to the lifting frame 48 through the floating joint 44 and the floating joint mounting plate 45 to provide the lifting power for the lifting frame 48. When the lifting cylinder 43 extends, the lifting frame 48 descends under the constraint of the slider 47. When the lifting cylinder 43 contracts, the lifting frame 48 ascends under the constraint of the slider 47.

[0037] As Figures 4 - 6 shown, the clamping and rotating mechanism 5 includes a slide cylinder 51, a rotating cylinder mounting plate 52, a rotating cylinder 53, a reinforcing rib three 54, a rotating support plate one 55, a rotating support plate two 56, a clamp one 57, a clamp two 58, a urethane rubber cushion block one 59, a urethane rubber cushion block two 510, a non-lubricated bushing 511, a guide rod 512, a fixing ring 513, a retaining ring 514, a bearing cover plate 515, a pin shaft 516, a bearing 517, and a spacer sleeve 518.

[0038] The slide cylinder 51 is fixed to the clamping and rotating mechanism mounting plate 411 of the main body lifting mechanism 4 by screws, and its position is adjustable. The rotating cylinder mounting plate 52 is fixed to the top end of the slide cylinder 51 by screws, and is strengthened and fixed on the sliding surface by the reinforcing rib three 54.

[0039] The rotating cylinder 53 is installed on the rotating cylinder mounting plate 52, and the center position of the rotating support plate two 56 is fixed to the center rotating surface of the rotating cylinder 53 by screws. The non-lubricated bushings 511 are installed at both ends of the rotating support plate two 56, and the guide rod 512 passes through the non-lubricated bushings 511 to provide strength and transmit torque.

[0040] The fixing ring 513 is installed on the guide rod 512, and the retaining rings 514 are installed at both ends of the guide rod 512 to limit the sliding of the guide rod 512. The bearing cover plate 515 is fixed to the rotating support plate one 55 by screws, and the bearing 517 is installed in the chamber between the bearing cover plate 515 and the rotating support plate one 55.

[0041] The pin shaft 516 passes through the bearing 517 and the spacer sleeve 518 and is fixed to the rotating cylinder mounting plate 52, and is reinforced with a nut 519. When the slide cylinder 51 acts, the rotating support plate one 55 and the rotating support plate two 56 contract simultaneously to drive the clamp to clamp.

By providing the polyurethane rubber cushion blocks, the softness and elasticity of the polyurethane rubber pads are utilized to make them ideal cushioning materials, which can absorb impact force and protect the material 2 from being damaged during the clamping process.

[0043] During the overall operation, the lifting cylinder 43 contracts in the initial state of the equipment, and the lifting frame 48 stops at the upper part of the equipment. When the material stops directly below the equipment, the lifting cylinder 43 extends to drive the lifting frame 48 to descend, and the clamping and rotating mechanism 5 stops on both sides of the material. The sliding table cylinder 51 extends, and the first rotating support plate 55 and the second rotating support plate 56 contract simultaneously to drive the fixture to clamp. The lifting cylinder 43 contracts to drive the lifting frame 48 to rise, providing a flipping space.

After rotation, the lifting cylinder 43 extends to drive the lifting frame 48 to descend, the sliding table cylinder 51 contracts, the fixture relaxes, the material is repositioned, and the lifting cylinder 43 contracts to return to the initial waiting state.
