Description

Technical Field

[0001] This utility model belongs to the technical field of column assembly equipment, and in particular relates to an automatic column assembly line mechanism based on multi-station collaboration. Background Technology

[0002] As a core load-bearing component in coal mining equipment and engineering machinery, the assembly precision, sealing performance, and structural stability of hydraulic columns directly determine the operational safety and service life of the equipment. This is especially true for hydraulic columns in coal mines, which operate under harsh conditions of high pressure, high dust, and high humidity for extended periods, demanding even stricter assembly quality standards. Currently, the column assembly industry still largely relies on a semi-automated, manually-driven assembly model. This results in fragmented equipment, poor process coordination, numerous technical defects and industry pain points, severely hindering the standardization, efficiency, and high-quality development of column assembly. Specific problems include: The cleaning process is unreasonable, resulting in insufficient cleanliness and equipment stability. In existing technologies, the outer cylinder, piston, and middle cylinder are often cleaned together using a single cleaning device, which easily exacerbates equipment wear and shortens lifespan. The fitting and assembly process is cumbersome, with a high risk of seal damage. In current assembly processes, the fitting of the piston, middle cylinder, assembly body, and outer cylinder often adopts a horizontal fitting-flipping vertical-assembly guide sleeve mode. Repeated flipping and hard friction can easily cause deformation of the seal ring. There is a high degree of reliance on manual labor, resulting in low assembly efficiency. Key processes such as guide sleeve loading, drilling, and screwing are still mainly operated manually. The process connections are fragmented, and the degree of automation throughout the entire process is low. The loading, cleaning, fitting, testing, and unloading processes of existing assembly lines are independent of each other, lacking integrated collaborative design, making it impossible to form a continuous production process. Overall assembly efficiency is low, making it difficult to meet the needs of modern manufacturing for intelligent and efficient production. Utility Model Content

The machine includes a drilling and nailing machine, a piston cylinder loading truss, an outer cylinder loading truss for transferring the outer cylinder to an outer cylinder cleaning machine, a piston cylinder sleeve tightening and turning machine for receiving the piston and cylinder, flipping them to a vertical position after horizontal loading to complete the sleeve assembly and tightening of the small guide sleeve, and a piston cylinder assembly and outer cylinder sleeve tightening and turning machine for receiving the piston cylinder small guide sleeve assembly and outer cylinder, flipping them to a vertical position after horizontal loading to complete the sleeve assembly and tightening of the large guide sleeve. The vertical no-load test bench includes a turning frame, a test workpiece, a workpiece fixture, a bottom support, and a fixed frame.

[0005] As a preferred embodiment of this utility model, it also includes a middle cylinder guide sleeve feeding robot and an outer cylinder guide sleeve feeding robot. The middle cylinder guide sleeve feeding robot is used to grab the middle cylinder guide sleeve from the middle cylinder guide sleeve tray and feed it to the piston cylinder sleeve assembly tightening and turning machine. The outer cylinder guide sleeve feeding robot is used to grab the outer cylinder guide sleeve from the outer cylinder guide sleeve tray and feed it to the piston cylinder assembly and outer cylinder sleeve assembly tightening and turning machine.

[0006] This setup replaces the manual feeding process, avoiding scratches and bumps to the guide sleeve caused by manual handling, improving feeding accuracy and efficiency, reducing labor costs, and achieving automation and precision in guide sleeve feeding.

[0007] As a preferred embodiment of this utility model, it also includes a conveying flatcar and a test truss. The conveying flatcar is used to transfer the column assembly to the vertical unloaded test bench, and the test truss is used to transfer the column assembly to the robotic drilling and nailing machine.

[0008] This setup enables automatic transfer of column assemblies between processes, avoiding the inefficiency and safety risks of manual handling. It also allows processes such as material loading, cleaning, fitting, testing, and drilling to form a continuous production flow, thereby improving overall assembly efficiency.

[0009] As a preferred embodiment of this invention, the flipping frame of the vertical no-load test bench can switch between vertical and horizontal states, and the test workpiece is subjected to no-load testing in the vertical state.

[0010] This setup allows for testing in a vertical position, preventing horizontal compression and wear on the piston rod and sealing ring, effectively protecting the seals and extending the life of the column seals. Simultaneously, the vertical layout saves horizontal workshop space, optimizes the production line layout, and improves space utilization.

[0011] As a preferred embodiment of this utility model, the outer cylinder receiving tray is used to store the outer cylinder, and the outer cylinder unloading gantry is used to grab the outer cylinder that has been cleaned by the outer cylinder cleaning machine and transfer it to the outer cylinder conveyor.

[0012] This setup enables automated connection of outer cylinder loading, cleaning, and conveying, avoiding the inefficiency and pollution risks of manual transfer, ensuring the stability of outer cylinder cleanliness, and providing a reliable foundation for subsequent assembly.

[0013] As a preferred embodiment of this utility model, the test bench pump station is used to provide hydraulic power for the vertical no-load test bench and the horizontal loading test bench, the robotic drilling and screw-tightening machine is used to automatically drill holes and tighten screws on the column assembly, the assembled column is transferred to the column tray, and the safety fence surrounds the assembly line to isolate the work area.

[0014] This setup provides stable hydraulic power to the test equipment through the test bench pump station, ensuring the accuracy of test data; robotic drilling and screwing replaces manual operation, reducing safety hazards; and safety fences effectively isolate the work area, avoiding cross-contamination risks between personnel and equipment, and improving the safety of the production line.

[0015] As a preferred embodiment of this utility model, the live column and cylinder feeding truss is used to grab the live column and cylinder on the live column and cylinder receiving tray and transfer them to the live column and cylinder cleaning machine, and the live column and cylinder unloading truss is used to grab the live column and cylinder that have been cleaned in the live column and cylinder cleaning machine and transfer them to the live column and cylinder conveyor line.

[0016] This setup enables independent feeding and cleaning of the piston column and the middle cylinder, avoiding cross-contamination caused by mixed cleaning with the outer cylinder, improving the cleanliness of the piston column and the middle cylinder, reducing the load rate of a single cleaning device, reducing equipment failures, and extending the service life of the equipment.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The outer cylinder and the piston cylinder are cleaned separately, avoiding insufficient cleanliness caused by mixed cleaning, improving the cleanliness of the piston and cylinder, and reducing the risk of seal damage. Separate cleaning reduces the load rate of a single cleaning machine, reduces equipment failures, and extends equipment life. After the piston and cylinder are horizontally loaded, they are flipped to a vertical fit, eliminating the need for a second horizontal flip before direct assembly and tightening of the small guide sleeve, simplifying the process and improving efficiency. The piston and cylinder small guide sleeve assembly is transported horizontally, avoiding the risks of vertical transport and improving transport safety. The piston and cylinder small guide sleeve assembly and the outer cylinder are horizontally loaded and flipped... The vertical fitting eliminates the need for a horizontal flip before direct assembly and tightening of the large guide sleeve, further simplifying the process. Vertical fitting prevents the middle cylinder and piston from tilting downwards, effectively protecting the sealing ring and reducing assembly losses. Robotic automatic feeding of the middle and outer cylinder guide sleeves replaces manual feeding, saving labor costs and improving feeding efficiency. The unloaded test bench adopts a vertical structure, which helps protect the protruding sealing ring and saves horizontal space, optimizing the workshop layout. Robotic automatic drilling and screw tightening of the column assembly replaces manual operation, improving drilling accuracy and screw tightening efficiency. Attached Figure Description

The test bench 10 includes a rotating frame 26, a robotic drilling and nailing machine 16, and a piston cylinder loading truss 24. The outer cylinder loading truss 1 is used to transfer the outer cylinder to the outer cylinder cleaning machine 3. The piston cylinder sleeve tightening and turning machine 7 is used to receive the piston and the cylinder, and after horizontal loading, it is turned to a vertical position to complete the sleeve assembly and tightening of the small guide sleeve. The piston cylinder assembly and outer cylinder sleeve tightening and turning machine 8 is used to receive the piston cylinder small guide sleeve assembly and the outer cylinder, and after horizontal loading, it is turned to a vertical position to complete the sleeve assembly and tightening of the large guide sleeve. The vertical no-load test bench 10 includes a turning frame 26, a test workpiece 27, a workpiece clamp 28, a bottom support 29, and a fixed frame 30.

[0023] Specifically, it also includes a middle cylinder guide sleeve loading robot 19 and an outer cylinder guide sleeve loading robot 18. The middle cylinder guide sleeve loading robot 19 is used to grab the middle cylinder guide sleeve from the middle cylinder guide sleeve tray 20 and load it onto the piston cylinder sleeve assembly tightening and turning machine 7. The outer cylinder guide sleeve loading robot 18 is used to grab the outer cylinder guide sleeve from the outer cylinder guide sleeve tray 17 and load it onto the piston cylinder assembly and outer cylinder sleeve assembly tightening and turning machine 8.

[0024] The above solution replaces the manual feeding process, avoids the guide sleeve from being bumped and scratched by manual handling, improves feeding accuracy and efficiency, reduces labor costs, and realizes the automation and precision of guide sleeve feeding.

[0025] Specifically, it also includes a conveyor flatcar 9 and a test truss 13. The conveyor flatcar 9 is used to transfer the column assembly to the vertical unloaded test bench 10, and the test truss 13 is used to transfer the column assembly to the robotic drilling and nailing machine 16.

[0026] By adopting the above solution, the column assembly is automatically transferred between processes, avoiding the inefficiency and safety risks of manual handling. This enables the processes of feeding, cleaning, fitting, testing, and drilling to form a continuous production process, thereby improving the overall assembly efficiency.

[0027] Specifically, the flip frame 26 of the vertical no-load test bench 10 can switch between vertical and horizontal states, and the test workpiece 27 is subjected to no-load test in the vertical state.

[0028] By adopting the above scheme, the test in the vertical state can avoid horizontal extrusion and wear of the piston rod and sealing ring, effectively protect the seals, and extend the life of the column seal; at the same time, the vertical layout saves horizontal workshop space, optimizes the production line layout, and improves space utilization.

[0029] Specifically, the outer cylinder receiving tray 2 is used to store the outer cylinder, and the outer cylinder unloading gantry 4 is used to grab the outer cylinder that has been cleaned by the outer cylinder cleaning machine 3 and transfer it to the outer cylinder conveyor 5.

[0030] The above solution achieves automated connection of outer cylinder loading, cleaning, and conveying, avoiding the inefficiency and pollution risks of manual transfer, ensuring the stability of the outer cylinder's cleanliness, and providing a reliable foundation for subsequent assembly.

[0031] Specifically, the test bench pump station 12 is used to provide hydraulic power for the vertical no-load test bench 10 and the horizontal loading test bench 11. The robotic drilling and screwing machine 16 is used to automatically drill holes and tighten screws on the column assembly. The assembled column is transferred to the column tray 15. The safety fence 14 surrounds the assembly line to isolate the work area.

[0032] With the above solution, the test bench pump station 12 provides stable hydraulic power to the test equipment, ensuring the accuracy of the test data; the robot drilling and screwing replaces manual operation, reducing safety hazards; and the safety fence 14 effectively isolates the work area, avoiding the risk of cross-contamination between personnel and equipment, and improving the safety of the production line.

[0033] Specifically, the live column and cylinder loading truss 24 is used to grab the live column and cylinder on the live column and cylinder receiving tray 25 and transfer them to the live column and cylinder cleaning machine 23. The live column and cylinder unloading truss 22 is used to grab the cleaned live column and cylinder in the live column and cylinder cleaning machine 23 and transfer them to the live column and cylinder conveyor line 21.

[0034] By adopting the above solution, independent feeding and cleaning of the piston column and the middle cylinder are achieved, avoiding cross-contamination caused by mixed cleaning with the outer cylinder, improving the cleanliness of the piston column and the middle cylinder, reducing the load rate of a single cleaning device, reducing equipment failures, and extending the service life of the equipment.

[0035] The working principle of this utility model: During use, in the material loading and cleaning stages: the outer cylinder is stored on the outer cylinder receiving tray 2 and is picked up and transferred to the outer cylinder cleaning machine 3 by the outer cylinder loading truss 1. The movable column and the middle cylinder are stored on the movable column and middle cylinder receiving tray 25 and are picked up and transferred to the independent movable column and middle cylinder cleaning machine 23 by the movable column and middle cylinder loading truss 24, so that the outer cylinder and the movable column and middle cylinder are cleaned separately. After cleaning, the outer cylinder is transferred to the outer cylinder conveyor 5 by the outer cylinder unloading truss 4, and the movable column and the middle cylinder are transferred to the movable column and middle cylinder conveyor line 21 by the movable column and middle cylinder unloading truss 22, thus completing the connection between cleaning and the next process. Fitting and Guide Set Assembly Stage: The piston cylinder fitting and tightening turning machine 7 receives the workpiece from the piston cylinder conveyor line 21, loads it horizontally, and then turns it to a vertical position to complete the fitting. At the same time, the cylinder guide sleeve loading robot 19 grabs the guide sleeve from the cylinder guide sleeve tray 20 and automatically loads it. The small guide sleeve is directly assembled and tightened in a vertical position to form a piston cylinder small guide set assembly and is horizontally transported. Then, this assembly and the outer cylinder conveyed by the outer cylinder conveyor 5 enter the piston cylinder assembly and outer cylinder fitting and tightening turning machine 8. After horizontal loading, it is turned to a vertical fitting. The outer cylinder guide sleeve loading robot 18 automatically loads the outer cylinder guide sleeve and directly tightens it to complete the large guide set assembly, forming the column assembly. Transfer and testing phase: The conveyor flatcar 9 transfers the column assembly to the vertical no-load test bench 10. The test bench flipping frame 26 switches to the vertical state. The workpiece is fixed by the workpiece clamp 28 and supported by the bottom support 29. The test bench pump station 12 provides stable hydraulic power to the vertical no-load test bench 10 and the horizontal loading test bench 11 to complete the no-load test. After the test, the test truss 13 transfers the column assembly to the next process. Drilling and material preparation stage: Robotic drilling and screwing machine 16 automatically drills holes in the column assembly and tightens screws. The assembled columns are then transferred to column tray 15 for storage. Safety fence 14 encloses the work area to isolate personnel and equipment from cross-contamination risks, ensuring safety throughout the entire operation and ultimately forming a closed-loop automated assembly process.
