Description

Technical Field

[0001] This invention belongs to the field of hydraulic cylinder processing technology, specifically relating to a hydraulic cylinder outer tube clamping device. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy, performing linear reciprocating motion (or oscillating motion). It is an actuator in a hydraulic transmission system, an energy conversion device that transforms hydraulic energy into mechanical energy. Hydraulic cylinders achieve reciprocating motion. The structural types of hydraulic cylinders are mainly divided into three categories: piston cylinders, plunger cylinders, and oscillating cylinders. When forming the outer cylinder tube of a hydraulic cylinder, it needs to be welded to the cylindrical part of the cylinder structure. However, in actual welding, manual welding is mostly used. But manual welding has the following problems... The problem is that during welding, the outer tube of the hydraulic cylinder needs to be manually moved, which is labor-intensive and inefficient. The outer tube is then manually clamped and fixed, and during the welding process, manual adjustment and correction are required until welding is complete. The heat generated at the welding joint can easily cause personal injury. This method is time-consuming, labor-intensive, and prone to errors, easily leading to misalignment during welding. Therefore, it is essential to provide a hydraulic cylinder outer tube clamping device with a reasonable structure, automatic clamping and positioning, reduced labor intensity, and applicability to different cylinder diameters.

[0012] The cam is provided with clamping rods on both the front and rear sides. The clamping rods are connected to the cam via rollers. A spring is provided between the clamping rods. A clamping seat is provided on the inner right side of each clamping rod. A base plate is provided below the clamping rod. The clamping rod is movably connected to the base plate via a shaft pin.

The rotating plate rotates around the bearing seat via a rotating shaft below, and drives the dovetail block to slide in the dovetail slot via a connecting clamp and sliding rod above. The dovetail block drives the cylinder body to move to the right via the pusher protrusion and the opening. After passing through the receiving plate and guide plate, it falls into the electrically controlled magnetic plate, which attracts the cylinder body. The driver drives the second bevel gear to rotate via the first bevel gear. The second bevel gear drives the receiving mechanism to rotate via the drive shaft, so that the cylinder body is in a vertical state. The lifting rod drives the receiving mechanism and the cylinder body to fall to the appropriate position. The clamping mechanism clamps the cylinder body, replacing manual adjustment and correction, and ensuring welding accuracy and quality.

A base 11 is provided below the driving mechanism 10. A lifting rod 12 is provided below the base 11. The lifting rod 12 is connected to the base 1 through a base plate 13.

[0024] This invention relates to a hydraulic cylinder outer tube clamping device. In use, a closed plate (not shown in the figure) is provided between the front and rear corner posts 51 and the left and right corner posts 51 of the feeding mechanism 5, making the feeding mechanism 5 a closed structure on both the front and rear sides and the left and right sides. Several cylinder body parts 6 can be pre-placed on the inclined platform 52 of the feeding mechanism 5, facilitating batch and continuous positioning welding operations. The width of the inclined platform 52 is slightly larger than the length of the cylinder body parts 6 to be welded. Furthermore, the distance between the inclined platform 52 and the bottom of the feeding mechanism 5, and the distance between the inclined platform 52 and the left corner post 51 of the feeding mechanism 5, are both 1.5 times the diameter of the cylinder body parts 6. The drive motor 54 drives the limiting plate 53 to rotate, causing it to enter the groove 55. At this time, the cylinder body parts 6 on the limiting plate 53 fall into the space formed between the inclined platform 52 and the left corner post 51 of the feeding mechanism 5. The drive motor 518 drives the feeding mechanism 5 through the drive handle 517 and the slot 516.

Above it, the dovetail block 59 slides in the dovetail groove seat 57 via the connecting clamp 513 and the sliding rod 511. The dovetail block 59 moves the cylinder body 6 to the right via the pushing protrusion 510 and the opening 56. After passing through the receiving plate 519 and the guide plate 520, it falls into the electrically controlled magnetic plate 94. The electrically controlled magnetic plate 94 attracts the cylinder body 6. The driver 102 drives the second bevel gear 105 to rotate via the first bevel gear 104. The second bevel gear 105 drives the receiving mechanism 9 to rotate via the drive shaft 106, so that the cylinder body 6 is in a vertical state. The lifting rod 12 drives the receiving mechanism 9 and the cylinder body 6 to fall to a suitable position. The clamping mechanism 8 clamps the cylinder body 6, replacing manual adjustment and correction, and ensuring welding accuracy and quality. This invention has the advantages of reasonable structure, automatic clamping and positioning, reduced labor intensity, and applicability to different cylinder diameters. Example

[0028] The feeding mechanism 5 is provided with a dovetail groove seat 57 below it. The dovetail groove seat 57 is provided with a dovetail block 59 inside it. The dovetail block 59 is provided with a pusher protrusion 510 on the upper inner side corresponding to the opening 56.

[0029] The dovetail seat 57 has a sliding groove 58 in front, and a sliding rod 511 is provided inside the sliding groove 58. A rotating plate 512 is provided below the sliding rod 511. The rotating plate 512 is connected to the sliding rod 511 through a connecting clamp 513.

The rotating plate 512 is movably connected to the bearing seat 514 through a rotating shaft 515. A waist-shaped slot 516 is provided below the rotating plate 512.

[0032] The clamping mechanism 8 includes a frame 81, a drive wheel 82 is arranged below the frame 81, a main shaft 83 is arranged above the drive wheel 82, and a cam 84 is arranged outside the main shaft 83.

[0033] The cam 84 is provided with clamping rods 87 on both the front and rear sides. The clamping rods 87 are connected to the cam 84 through rollers 86. A spring 812 is provided between the clamping rods 87. A clamping seat 88 is provided on the inner right side of each clamping rod 87. A base plate 89 is provided below the clamping rods 87. The clamping rods 87 are movably connected to the base plate 89 through a shaft pin 811. A through hole 810 is provided inside the base plate 89.

[0034] A grooved wheel 813 is provided above the cam 84, an adjusting wheel 815 is provided on the right side of the grooved wheel 813, and an adjusting screw 816 is provided above the adjusting wheel 815. The adjusting screw 816 passes through the frame 81 and is connected to the adjusting wheel 815.

[0035] In this embodiment, the working principle of the clamping mechanism is as follows: the driving wheel provides the power source, and the driving wheel drives the cam to rotate through the main shaft. The rotation radius of the cam changes, and the cam drives the clamping rod to rotate around the shaft pin. The clamping rod drives the clamping seat to perform the gripping action. The clamping rod contacts the cam through the roller, making the connection smoother. The spring plays a pulling role when the clamping seat performs the gripping action, assisting in a firm and reliable clamping. The grooved wheel is connected to the adjusting wheel, and the adjusting screw can change the height of the cam through the adjusting wheel. Since the cam is a cone, the range of rotation of the clamping rod around the shaft pin can be adjusted, thereby adjusting the gripping radius of the clamping seat. This allows it to automatically clamp and position cylinder bodies of different specifications and sizes, making it suitable for different cylinder diameters and greatly improving its practicality.

[0036] This invention relates to a hydraulic cylinder outer tube clamping device. In use, a closed plate (not shown in the figure) is provided between the front and rear corner posts 51 and the left and right corner posts 51 of the feeding mechanism 5, making the feeding mechanism 5 a closed structure on both the front and rear sides and the left and right sides. Several cylinder body parts 6 can be pre-placed on the inclined platform 52 of the feeding mechanism 5, facilitating batch and continuous positioning welding operations. The width of the inclined platform 52 is slightly larger than the length of the cylinder body parts 6 to be welded. Furthermore, the distance between the inclined platform 52 and the bottom of the feeding mechanism 5, and the distance between the inclined platform 52 and the left corner post 51 of the feeding mechanism 5, are both 1.5 times the diameter of the cylinder body parts 6. The drive motor 54 drives the limiting plate 53 to rotate, causing it to enter the groove 55. At this time, the cylinder body parts 6 on the limiting plate 53 fall into the space formed between the inclined platform 52 and the left corner post 51 of the feeding mechanism 5. The drive motor 518 drives the feeding mechanism 5 through the drive handle 517 and the slot 516. The rotating plate 512 moves, and below it rotates around the bearing seat 514 via the rotating shaft 515. Above it, the dovetail block 59 slides in the dovetail groove seat 57 via the connecting clamp 513 and the sliding rod 511. The dovetail block 59 moves the cylinder body 6 to the right via the pushing protrusion 510 and the opening 56. After passing through the receiving plate 519 and the guide plate 520, it falls into the electrically controlled magnetic plate 94. The electrically controlled magnetic plate 94 attracts the cylinder body 6. The driver 102 drives the second bevel gear 105 to rotate via the first bevel gear 104. The second bevel gear 105 drives the receiving mechanism 9 to rotate via the drive shaft 106, so that the cylinder body 6 is in a vertical state. The lifting rod 12 drives the receiving mechanism 9 and the cylinder body 6 to fall to a suitable position. The clamping mechanism 8 clamps the cylinder body 6, replacing manual adjustment and correction, and ensuring welding accuracy and quality. This invention has the advantages of reasonable structure, automatic clamping and positioning, reduced labor intensity, and applicability to different cylinder diameters.
