Abstract
Description
Technical Field
[0001] This invention relates to the field of hydraulic cylinder manufacturing technology, and in particular to a heavy-duty hydraulic cylinder rotary vertical assembly equipment and method. Background Technology
[0002] Hydraulic cylinders, as efficient hydraulic actuators, are capable of converting hydraulic energy into mechanical energy and driving linear reciprocating or oscillating motion. Their core components include the cylinder barrel, piston rod, and cylinder head. Thanks to their simple structure and stable operation, hydraulic cylinders can achieve smooth reciprocating motion without a reduction gear, and are highly favored due to their lack of transmission backlash, making them widely used in the hydraulic systems of various mechanical equipment.
[0003] In the field of hydraulic cylinder assembly, the equipment currently on the market is mainly divided into two categories: horizontal assembly and vertical assembly. Horizontal assembly uses a horizontal platform to support the piston rod, which is then inserted into the cylinder by horizontal pushing. The advantage of this method is that it is easy to integrate with gantry robots to form a highly efficient automated assembly line, significantly improving production efficiency. However, when dealing with large and heavy-duty hydraulic cylinders, the horizontal platform cannot fully support the piston rod, causing the piston rod end to sag due to its own weight, thus affecting the assembly accuracy with the cylinder.
[0004] In contrast, vertical assembly uses a crane to lift the piston rod and vertically place it into the cylinder. This method effectively reduces the impact of the piston rod's weight on assembly accuracy and significantly improves assembly quality. However, the drawback of vertical assembly is its heavy reliance on manual operation of the crane, which is not only labor-intensive but also lacks constraints in the lifting operation itself, posing higher safety risks. Furthermore, the lower level of automation limits the improvement of production efficiency. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a heavy-duty hydraulic cylinder rotating vertical assembly equipment and method that does not require manual crane hoisting. It can simultaneously take into account the advantages of horizontal assembly and vertical assembly, significantly improve the degree of automation of assembly while ensuring assembly accuracy, greatly reduce the labor intensity of workers, avoid the safety hazards of traditional hoisting, and thus effectively improve the production efficiency of products.

An arc-shaped rack D20 that is connected to the drive gear D is fixed on the swing block.
[0025] Please refer to Figure 1-2 In the above structure, bases A22, B23, C and D are all slidably mounted on the guide rail by sliders and are respectively connected to a power mechanism. The power mechanism can be a linear mechanism driven by a power source common in the field, such as a screw and nut mechanism or a gear and rack mechanism.
[0026] Please refer to Figure 1-6 A method for rotating and vertically assembling a heavy-duty hydraulic cylinder is disclosed. This method utilizes the aforementioned rotating and vertical assembly equipment for heavy-duty hydraulic cylinders. Taking the assembly of a certain model of high-load single-stroke hydraulic cylinder of this equipment as an example, the front end of the piston rod has a mounting through hole, the cylinder head is fitted into the middle rear part, and the rear end is the piston. After the piston and cylinder are initially aligned at the rear end of the piston rod, the entire piston rod is vertically and slowly assembled. Finally, the threads between the cylinder head and cylinder are tightened. The specific steps are as follows: 1) Component Installation: First, the positions of each unit on the load-bearing beam 5 are pre-controlled or manually adjusted according to the product specifications and model. Then, the truss robot grabs the cylinder and places it at the rear end of the load-bearing beam 5. The cylinder head clamping unit 2 automatically adjusts its position to clamp the tail of the cylinder. The drive motor C16 of the cylinder body clamping unit 3 is started, and the clamping end of the centering clamping mechanism 17 clamps the front of the cylinder. The two work together to fix the position of the cylinder. Next, the truss robot grabs the piston rod and places it at the front end of the load-bearing beam 5. The drive motor B of the rod head clamping unit 1 is started. The chuck B9 drives the sensor 10 to rotate around the piston rod to identify the position of its head through hole. Then, the angle is adjusted so that the two jaws on the chuck B9 are aligned with the hole and clamping is completed. Finally, the lifting cylinder of the support tightening unit 4 is started to adjust the height of the support surface to support the piston rod. The rod head clamping unit 1 works together to complete the horizontal positioning of the piston rod. 2) Horizontal docking: According to the product model, the two-degree-of-freedom servo adjustment mechanism 8 of the rod head clamping unit 1 and the lifting adjustment mechanism 19 of the support tightening unit 4 are activated to finely adjust the piston rod to the set axis position (i.e., the cylinder axis position); the rod head clamping unit 1 and the support tightening unit 4 move synchronously, so that the rear end of the piston rod (piston end) enters the cylinder to complete the docking; 3) Turning and positioning: The head frame positioner 6 and the tail frame positioner 7 start to drive the bearing beam 5 and all units on the crossbeam to rotate 90°, and the bearing beam 5 switches to the vertical position; 4) Vertical loading: The support tightening unit 4 disengages from the piston rod and adjusts its position to the front end of the cylinder to avoid interference with the stop of the rod head clamping unit 1 during subsequent loading; the rod head clamping unit 1 moves down to load the piston rod into place. During the loading process, its two-degree-of-freedom servo adjustment mechanism 8 can adjust the position of the piston rod axis at any time according to the feedback from the front end to ensure smooth loading. Specifically, if there is a deviation between the piston rod axis and the cylinder axis during loading, an asymmetrical resistance is formed between the piston rod and the cylinder. This resistance is fed back to the power motor through the gear and rack mechanism. The power motor drives the chuck B9 to adjust its displacement according to the set algorithm to ensure that the piston rod and the cylinder are coaxial.
[0027] 5) Cylinder head tightening: After the piston rod is loaded, the cylinder head reaches the front end of the cylinder. The rod head clamping unit 1 releases the piston rod and moves upward to make room. The support tightening unit 4 moves upward to the cylinder head position and the center clamping mechanism 21 clamps the clamping and tightening area of the cylinder head. After the drive motor D drives the swing block to rotate 120°, it is released and waits for it to reset. After the swing block resets, it is clamped again. This cycle is repeated several times until the cylinder head is tightened.
[0028] 6) Picking and transporting: The cylinder head clamping mechanism and the cylinder body clamping mechanism release their clamping, and the gantry robot grabs the assembled hydraulic cylinder and transports it to the next process.
[0029] The rod head clamping unit 1 of the present invention is rotatably connected to the piston rod, which can transform the self-weight of the piston rod that hinders assembly in the existing equipment into an aid to vertical centering of the piston rod during the vertical filling process; the support and tightening unit 4 integrates the two major functions of support and tightening, which can support the piston rod in the horizontal position and rotate and tighten the cylinder head in the vertical position, realizing the diversification and efficiency of functions.
[0030] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
