Description

Technical Field

[0001] The present invention relates to the technical field of laser cladding processing, and particularly to a laser cladding strengthening device for the outer rubber hose of a high wear-resistant and extrusion-resistant hydraulic oil pipe. Background Art

[0002] In modern industrial production, hydraulic systems are widely used in various mechanical equipment, from large construction machinery to precision industrial automation equipment. As a key component of the hydraulic system, the hydraulic oil pipe undertakes the important task of transmitting high-pressure liquid. During long-term use, traditional outer rubber hoses of hydraulic oil pipes face many severe challenges. On the one hand, in a complex working environment, the oil pipe needs to frequently withstand the impact and friction of high-pressure liquid, which makes the outer rubber hose extremely prone to wear. On the other hand, in some working conditions with strong extrusion, such as cranes and excavators in construction, the hydraulic oil pipe may be squeezed by mechanical components. Once the outer rubber hose is damaged, it will not only affect the normal operation of the hydraulic system, leading to equipment failures, but may even cause safety accidents. To improve the wear-resistant and extrusion-resistant performance of the outer rubber hose of the hydraulic oil pipe, laser cladding technology has gradually become a research and application hotspot. Laser cladding is a process method that adds a cladding material to the surface of a substrate and uses a high-energy laser beam to melt and solidify it together with a thin layer of the substrate surface. It can significantly improve the surface performance without changing the overall performance of the substrate. The present invention is a laser cladding strengthening device for the outer rubber hose of a high wear-resistant and extrusion-resistant hydraulic oil pipe.

[0003] Existing laser cladding strengthening devices for the outer rubber hose of hydraulic oil pipes cannot accurately adjust the placement and clamping positions according to the length and diameter of the oil pipe, making it difficult to adapt to various oil pipes. The cladding processing accuracy is low, and high-quality processing cannot be guaranteed. The feeding and material handling efficiency is low and unstable, highly dependent on manual labor, and prone to shaking, severely restricting the improvement of the efficiency and quality of laser cladding processing for the outer rubber hose of hydraulic oil pipes.

[0015] The present invention provides a laser cladding strengthening device for the outer rubber tube of a high wear-resistant and anti-extrusion hydraulic oil pipe, which has the following beneficial effects: In the present invention, the rotating plate and the universal connecting rod on the carrier plate cooperate with each other. By flexibly stretching two groups of first hydraulic rods, the positions of the first plate and the second plate can be easily adjusted, and precise adjustment can be made according to the length of the oil pipe, ensuring that various oil pipes can be placed stably and steadily on the device. The rotating disk on the mounting plate rotates flexibly under the drive of the second hydraulic rod, and drives the clamping plate to act with the help of the movable block and the movable seat. The clamping plate can not only precisely clamp the front end of the oil pipe, but also accurately adjust the clamping force according to the slight difference in the pipe diameter of the oil pipe, so as to tightly fix oil pipes with different diameters. When the third hydraulic rod shrinks, components such as the movable ring, the support rod and the spring work together, and can precisely adjust the clamping force on the rear end of the oil pipe according to the size of the oil pipe diameter, realizing stable clamping. This precise clamping method that coordinates the front end and the rear end greatly enhances the adaptability of the device to various hydraulic oil pipes and provides a solid guarantee for subsequent processing.

[0016] In addition, in the present invention, the first motor on the seat plate drives the rotating rod and the gear to operate through the sprocket chain drive, and then drives the tooth disk to rotate, so that the mounting plate and the oil pipe fixed on it can realize multi-angle rotation, realizing the all-round cladding processing of the outer rubber tube of the oil pipe. The stabilizing wheel on the adjusting plate is in close contact with the tooth disk groove, and during the rotation of the tooth disk, its stability is effectively guaranteed, significantly improving the processing accuracy and ensuring that the quality of the laser cladding reaches a high standard.

[0017] In addition, in the present invention, the feeding and material handling processes are efficient and convenient. When the No. 3 motor is started, the idler rollers start to rotate, pushing the carrier plate to move to the right and smoothly conveying it onto the lifting seat. Subsequently, the No. 4 motor drives the lead screw, causing the lifting seat to move upward on the second rail plate. When the height of the carrier plate rises above the feeding chute, the No. 5 hydraulic rod is extended to make the crossbar extend, and the carrier plate on the lifting seat is steadily lifted by the support piece. Then, the No. 5 motor is operated, which drives the first driving column to rotate, and drives the carrier plate on the moving plate to move to the left through the third connecting belt. When the carrier plate moves to the position of the pressing plate, the No. 6 hydraulic rod is extended to make the pressing plate extend, and the No. 7 hydraulic rod is contracted to lower the height of the pressing plate, and the pressing piece is thereby accurately pressed down on the carrier plate. Through the collaborative action of the support piece and the pressing piece, the accurate position fixation of the carrier plate is achieved. This series of automated operations greatly improves the feeding efficiency and accuracy, significantly reduces the manual labor intensity, and effectively prevents the shaking of the carrier plate during the laser cladding process, providing strong support for the stability of the processing process.

[0018] In addition, in the present invention, after the oil pipe cladding processing is completed, the No. 6 motor is operated to drive the second movable plate to slide to the right on the fourth rail plate through the fourth connecting belt. At the same time, the No. 7 hydraulic rod accurately adjusts the height of the second support plate, and the carrier plate is lifted upward by the second support plate. Then, the No. 6 motor is operated in the reverse direction to move the second support plate to the left, and finally, the carrier plate is smoothly output to the left. The whole process has smooth operation and convenient discharging, greatly improving the working efficiency and reducing the material handling time after processing.

[0019] In addition, in the present invention, the positioning and operation of the laser cladding head have high flexibility and efficiency. The No. 7 motor drives the driving rod to rotate, and drives the sliding seat A and the sliding seat B to move horizontally on the first rail rod through the fifth connecting belt, enabling the laser cladding head to be quickly moved to the general working area. The No. 8 motor drives the moving seat to slide on the second rail rod through the seventh connecting belt to further refine the adjustment of the horizontal position to ensure the accuracy of the positioning. The No. 9 motor drives the lifting plate to move up and down on the fifth rail plate through the eighth connecting belt to achieve precise adjustment of the height of the laser cladding head. This multi-dimensional and flexible positioning method enables the laser cladding head to quickly and accurately reach the specified processing position, greatly improving the laser cladding processing efficiency and quality, fully meeting the complex laser cladding strengthening requirements of hydraulic oil pipe outer rubber hoses with different shapes and sizes, and providing a reliable guarantee for the production of high-quality hydraulic oil pipe outer rubber hoses.

[0032] Working principle of the present invention: According to the length of the oil pipe, two groups of first hydraulic rods 133 are flexibly telescoped. By rotating the plate 1311 and the universal connecting rod 1312, the positions of the first plate 131 and the second plate 132 are adjusted to ensure that the oil pipe can be placed stably on the carrier plate 13. On the mounting plate 15, the second hydraulic rod 1531 is started, and its piston rod drives the rotating disk 152 to rotate. With the help of the movable block 1521 and the movable seat 1522, the clamping plate 1523 is driven to act, and the clamping force is accurately adjusted according to the pipe diameter of the oil pipe to tightly fix the front end of the oil pipe. On the second plate 132, the third hydraulic rod 165 is contracted, and components such as the movable ring 163, the support rod 1622, and the spring work together to accurately adjust the clamping force on the rear end of the oil pipe according to the pipe diameter size to achieve stable clamping. In addition, the first motor 1411 on the seat plate 14 drives the rotating rod 142 and the gear to operate through the sprocket chain drive, and then drives the tooth disk 143 to rotate. The stabilizing wheel 1451 on the adjusting plate 145 is in close contact with the groove of the tooth disk 143 to ensure the rotational stability of the tooth disk 143, enabling the mounting plate 15 and the oil pipe fixed thereon to rotate at multiple angles to prepare for cladding. The third motor 171 is started, and the idler roller 1211 starts to rotate, pushing the carrier plate 13 to move to the right and smoothly conveying it to the lifting seat 192. Subsequently, the fourth motor 1941 drives the lead screw 193 to move the lifting seat 192 upward on the second rail plate 191. When the height of the carrier plate 13 rises above the feeding chute 23, the fifth hydraulic rod 241 is extended to make the cross bar 243 extend, and the carrier plate 13 on the lifting seat 192 is steadily lifted by the supporting piece 2431. Then, the fifth motor 222 is operated, and its output shaft drives the driving column 221 to rotate, and through the third connecting belt 22, the carrier plate 13 on the moving plate 24 is driven to move to the left. When the carrier plate 13 moves to the position of the pressing plate 253, the sixth hydraulic rod 252 is extended to make the pressing plate 253 extend, and the seventh hydraulic rod 2611 is contracted to lower the height of the pressing plate 253, and the pressing piece 2531 is accurately pressed down on the carrier plate 13 accordingly. Through the cooperative action of the supporting piece 2431 and the pressing piece 2531, the accurate position fixation of the carrier plate 13 is achieved. The seventh motor 341 is started through the controller 31, and the pulley on its output shaft drives the driving rod 321 to rotate through the sixth connecting belt 342. The pulley on the driving rod 321 drives the sliding seat A 35 and the sliding seat B 36 to move horizontally on the first rail rod 33 through the fifth connecting belt 323, quickly moving the laser cladding head 376 to the approximate working area. The eighth motor 363 is started, and the pulley on its output shaft drives the moving seat 362 to slide on the second rail rod 361 through the seventh connecting belt 364 to further refine the adjustment of the horizontal position of the laser cladding head 376 to ensure accurate positioning. The ninth motor 371 is started, and the pulley on its output shaft drives the lifting plate 374 to move up and down on the fifth rail plate 373 through the eighth connecting belt 372 to achieve the accurate adjustment of the height of the laser cladding head 376, enabling the laser cladding head 376 to quickly and accurately reach the specified processing position.Laser cladding strengthening processing is carried out on the outer rubber hose of the hydraulic oil pipe. During the processing, the first motor 1411 continuously operates to drive the oil pipe to rotate at multiple angles to achieve full-round cladding. After the cladding processing of the oil pipe is completed, the sixth motor 2641 is run. The pulley on its output shaft drives the second movable plate 261 to slide to the right on the fourth rail plate 26 through the fourth connecting belt 2651. At the same time, the seventh hydraulic rod 2611 is started to extend its piston rod to accurately adjust the height of the second support plate 263. The carrier plate 13 is lifted upward through the second support plate 263. Then, the sixth motor 2641 is run in reverse to move the second support plate 263 to the left. Finally, the carrier plate 13 is smoothly output to the left to complete the entire work process.
