Description

Technical Field

[0001] This utility model relates to agricultural machinery assembly technology, specifically an agricultural tractor assembly line. Background Technology

[0002] Since my country's reform and opening up, the national economy has experienced rapid growth. "Technological innovation and independent innovation" have become the mainstream of my country's current industrial development, and my country's industry is gradually developing towards intensive, energy-saving, emission-reducing, and low-carbon directions. Currently, the assembly of agricultural tractor assemblies in the domestic market is relatively scattered and unsystematic. This is because the assembly process of a complete machine differs from that of individual components; there are many parts, the structure is complex, and the assembly process is more flexible, requiring assembly workers to make adjustments themselves. Most assembly follows the old-fashioned group assembly model. This assembly model is inefficient and inconvenient for on-site management. This is mainly reflected in: chaotic placement of workpieces on-site, long transportation time, and the need for more personnel to track progress. At the same time, it requires highly skilled assembly workers because they need to master many process steps, making it difficult for newcomers to learn. All workpieces are placed in the workshop, occupying a large area and reducing space utilization. The chaotic site and poor working environment easily lead to an increased error rate in the assembly of parts and bolts. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an agricultural tractor assembly line to address the shortcomings of the existing technology.

[0004] The technical solution of this utility model is to include more than 3 workbenches (2), and load-bearing wheels (6) are provided below the workbenches (2). The workbenches (2) are set on the guide rail (1), and the guide rail (1) is provided with a pushing mechanism that pushes the workbenches (2) to move forward synchronously. The pushing mechanism includes a push plate (3) and a hydraulic cylinder (5) that drives the push plate (3) to move along the guide rail (1). The number of push plates (3) is the same as that of the workbenches (2) and they are evenly distributed. The push plates (3) are located between the connecting plates (11) and are connected by a rotating shaft (13). A spring plate (15) is provided below the front of the push plate (3). One end of the spring plate (15) is hinged to the connecting plate (11) and the other end slides freely. At the same time, one end of the connecting plate (11) is hinged to the output shaft of the hydraulic cylinder (5), and an evenly distributed lower conveying roller assembly (10) is provided below the connecting plate (11).

[0005] The push plate (3) is provided with a slot (7) at the top. The push plate (3) pushes the workbench (2) forward one station synchronously through the slot (7) at the top. A limit tube (12) is welded between the two connecting plates (11). The limit tube (12) is located above the tail end of the push plate (3).

[0006] The push plate (3) is provided with a contact block (14) of the same width as the spring sheet (15).

[0007] A sealing plate (4) of the same length as the connecting plate (11) is welded on the top of the sealing plate (4), and the sealing plate (4) is provided with a clearance groove (8) for the clearance push plate (3).

[0008] The front end of the clearance groove (8) is provided with a baffle (9) that can move back and forth. The baffle (9) is provided with a U-shaped long groove and is fixed to the sealing plate (4) by bolts.

[0009] The stroke of the oil cylinder (5) is greater than or equal to the distance between the push plates (3).

[0010] The advantages of this invention compared to existing technologies are as follows: This assembly line integrates product cleaning, painting, assembly, and conveying into a complete production line, shortening assembly time, improving production efficiency, and ensuring product assembly accuracy. The assembly line is equipped with different workstations and tooling to accommodate the assembly of different tractor assemblies. The entire tractor assembly production line is driven by hydraulic cylinders, further enhancing production efficiency. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] This utility model is an agricultural tractor assembly line, including more than 3 workbenches 2, with load-bearing wheels 6 below the workbenches 2, and all workbenches 2 are mounted on guide rails 1.

[0017] The guide rail 1 is equipped with a mechanism that pushes all workbenches 2 forward synchronously. This mechanism includes push plates 3, which are the same number as the number of workbenches 2 and are evenly distributed, and hydraulic cylinders 5 that provide pushing power. The push plates 3 are located between the connecting plates 11 and connected by a rotating shaft 13. In this way, the push plates 3 can rotate around the rotating shaft 13. A spring piece 15 is provided on the lower front of the push plate 3. One end of the spring piece 15 is hinged to the connecting plate 11, and the other end slides freely. The push plate 3 is provided with a contact block 14 of the same width as the spring piece 15. A sealing plate 4 of the same length as the connecting plate 11 is welded on the top of the connecting plate 11. The sealing plate 4 is provided with a clearance groove 8 to avoid the push plate 3. The front end of the clearance groove 8 is provided with a baffle 9 that can move back and forth. The baffle 9 is provided with a U-shaped long groove and is fixed to the sealing plate 4 with bolts.

[0018] The top of the push plate 3 is provided with a slot 7 for pushing the workbench 2, and a limiting tube 12 is welded between the connecting plates 11, located above the tail end of the push plate 3.

[0019] Meanwhile, one end of the connecting plate 11 is hinged to the output shaft of the cylinder 5, and the lower part of the connecting plate 11 is provided with evenly distributed lower conveying roller assembly 10 to reduce friction. The extension and retraction of the cylinder 5 drives the connecting plate 11 and the push plate 3 to move together along the direction of the guide rail 1. The push plate 3 pushes the workbench 2 to move forward one station synchronously. The stroke of the cylinder 5 is greater than or equal to the distance between the push plates 3.

[0020] The specific working principle is as follows:

[0021] During normal operation, the spring 15 keeps the push plate 3 in a tilted state, and the slot 7 is engaged with the bottom of the workbench 2. After each process is completed, the hydraulic cylinder 5 is activated, and the push plate 3 pushes all the workbench 2 forward to the next process. Then the hydraulic cylinder 5 retracts, and the push plate 3, under the gravity of the workbench 2, compresses the spring 15 and moves downward. After the hydraulic cylinder 5 retracts, since there is no workbench 2, the spring 15 rebounds, and the push plate 3 tilts up again, so that the slot 7 is engaged with the bottom of the workbench 2, repeating the previous action. The workbench 2 at the front, which has been assembled, is unloaded from the tractor and sent back to the starting point to complete the cycle.
