Detailed Implementation

[0022] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0023] like Figures 1 to 6 As shown, a forklift tire assembly pressing device includes a hydraulic press 7, a tire press head 6, a frame 20, frame supports 16, a conveyor chain 2, conveyor chain guide rails 22, chain plates 9, and a conveyor chain drive mechanism 13. Multiple frame supports 16 are fixedly connected to the bottom of the frame 20. Conveyor chain guide rails 22 are symmetrically arranged on both sides of the frame 20. Two identical conveyor chains 2 are connected end-to-end and respectively mounted on the conveyor chain guide rails 22 on both sides. The two conveyor chains 2 are connected as a whole by evenly distributed chain plates 9 and rotate under the drive of the conveyor chain drive mechanism 13. The conveyor chain drive mechanism 13 is fixedly connected to the frame 20. A hydraulic press 7 is installed in the middle of the frame 20. A tire pressure head 6 is fixedly connected to the motion output end of the upper cylinder of the hydraulic press 7. The hydraulic press base 1 at the bottom of the hydraulic press 7 is installed in the middle of the annular conveyor chain 2. Six positioning fixtures for tire assemblies 5 are evenly distributed on the chain plate 9 of the annular conveyor chain 2. Three of the positioning fixtures are located on the upper chain belt of the annular conveyor chain 2, which are successively called the loading station 17, the pressing station 15, and the unloading station 14. The remaining three positioning fixtures are located on the lower chain belt of the annular conveyor chain 2. A pusher plate 10 is provided at the corresponding position of each positioning fixture. The pusher plate 10 is fixedly connected to the corresponding chain plate 9.

[0024] In this embodiment, the annular conveyor chain 2, driven by the conveyor chain drive mechanism 13, rotates continuously with six positioning fixtures evenly distributed on the conveyor chain 2, forming an assembly line operation. On the workbench of the frame 20, the upper chain of the annular conveyor chain 2 always maintains three positioning fixtures, namely the loading station 17, the pressing station 15, and the unloading station 14. The three stations operate simultaneously. After the operation is completed, the annular conveyor chain 2 drives each station to move forward one station and continue the operation, forming an assembly line that repeats continuously. Each positioning fixture is provided with a pusher plate 10 at its corresponding position. The function of the pusher plate 10 is to push the assembled tire assembly 5 from the unloading station 14 onto the transport vehicle.

[0025] The positioning fixture of the tire assembly 5 includes a positioning base 18, a positioning plate 19, and a T-shaped plate 25. The upper surface of the positioning plate 19 is evenly distributed with a plurality of anti-rotation positioning holes for the tire bolts 4. The positioning plate 19 is fixedly connected to the top of the positioning base 18, and the bottom of the positioning base 18 is fixedly connected to the corresponding chain plate 9. A T-shaped plate 25 is also fixedly connected to the lower part of the chain plate 9 directly below the positioning base 18. Its T-shaped cross section is perpendicular to the movement direction of the transmission chain 2.

[0026] In this embodiment, the positioning base 18, positioning plate 19 and T-shaped plate 25 are fixedly connected to the corresponding chain plate 9 by bolts to form a whole. Multiple tire bolts 4 are placed in the anti-rotation positioning holes of the positioning plate 19 to limit and determine the assembly position of the tire assembly 5. The T-shaped plate 25 is located below each station of the positioning fixture and mainly plays the role of guiding, bearing pressure and resisting tension.

[0027] The pressing station 15 is located directly below the tire pressure head 6 of the hydraulic press 7. The T-shaped plate 25 of its positioning fixture is in full contact with a pressure plate 3 below. The pressure plate 3 is fixedly connected to the hydraulic press base 1. The upper surface of the pressure plate 3 is provided with a sliding guide angle, which is consistent with the movement direction of the conveyor chain 2.

[0028] In this embodiment, the function of the tire indenter 6 is to press the split wheel rim on the pressing station 15 into the inner ring of the tire; the T-shaped plate 25 below the pressing station 15 slides above the pressure plate 3 through the sliding guide angle and makes full contact with the pressure plate 3, and its function is to bear the pressure of the tire indenter 6 on the positioning fixture; the sliding guide angle on the pressure plate 3 is consistent with the movement direction of the conveyor chain 2 to ensure the sliding guiding function of the sliding guide angle;

[0029] A lifting mechanism is provided below the unloading station 14. The lifting mechanism includes lifting cylinders 21, lifting brackets 23, and lifting plates 12. One end of each of the two lifting cylinders 21 is hinged to the frame 20, and the other end is hinged to the two outer sides of the lifting bracket 23. The top of each side of the lifting bracket 23 is fixedly connected to the two corresponding lifting plates 12. The lifting plates 12 are disposed between the chain plate 9 and the tire assembly 5 without contact. A T-slot plate 24 is provided below the unloading station 14. The T-slot plate 24 is fixedly connected to the frame 20. When the positioning fixture moves to the unloading station 14, the T-slot plate 25 at the bottom of the positioning fixture is located in the T-slot plate 24.

[0030] In this embodiment, a lifting mechanism is provided below the unloading station 14. After the tire assembly 5 is assembled, the lifting cylinder 21 of the lifting mechanism lifts the tire assembly 5 through the lifting plate 12, completing the unloading action of the tire assembly 5. The T-shaped groove plate 24 below the unloading station 14 is fixedly connected to the frame 20. The T-shaped plate 25 at the bottom of the positioning fixture is located in the T-shaped groove plate 24. When the lifting mechanism lifts the tire assembly, the T-shaped plate 25 at the bottom of the positioning fixture is restricted in the T-shaped groove plate 24, so that the positioning fixture of the unloading station 14 remains in place, making it easier for the lifting mechanism to lift the tire assembly 5.

[0031] like Figure 1 As shown, the frame support 16 is an adjustable support; in this embodiment, the frame support 16 is an adjustable support, which facilitates the installation of the frame 20 on the ground.

[0032] like Figure 1 As shown, the conveyor chain drive mechanism 13 is located at one end of the unloading station 14 of the frame 20. In this embodiment, the conveyor chain drive mechanism 13 is located at one end of the unloading station 14 of the frame 20, which facilitates the uniform force on the conveyor chain 2 and the smooth movement transmission.

[0033] like Figure 1 As shown, the connection between the positioning plate 19 and the positioning base 18 is a quick-change connection. In this embodiment, because the tire assembly 5 has different sizes and models, different models of positioning plates 19 need to be replaced. Therefore, the positioning plate 19 and the positioning base 18 are connected by a quick-change connection to facilitate the replacement of the positioning plate 19.

[0034] like Figure 1 As shown, the sliding guide angle on the upper surface of the pressure plate 3 is 15°, which facilitates sliding and reduces friction.

[0035] like Figure 1 As shown, a displacement sensor (8) is provided on the top of the hydraulic press (7). The displacement sensor (8) is linked with the tire pressure head (6), which can ensure the safe and reliable displacement stroke of the tire pressure head (6).

[0036] like Figure 3 As shown, the hydraulic press (7) is a vertical four-column hydraulic press. In this embodiment, the four-column hydraulic press has low cost, is easy to maintain, and facilitates the design, layout and installation of the equipment.

[0037] In the above-described implementation scheme, the fixed connection can be made in various ways, such as welding, riveting, and threaded connection, with threaded connection being preferred, as it facilitates disassembly and installation.

[0038] Furthermore, the hydraulic press 7, frame 20, conveyor chain 2, and conveyor chain drive mechanism 13 described in this utility model are all mature existing technologies and common knowledge, and will not be explained in detail in this utility model.

[0039] The specific working principle of this utility model is as follows:

[0040] First, at the loading station 17, insert the corresponding tire bolt 4 into the anti-rotation positioning hole of the positioning plate 19 of the positioning fixture, then insert the threaded hole of the split wheel rim into the tire bolt 4, and after placing the assembly parts of the tire assembly 5 on the positioning fixture in sequence, start the conveyor chain 2 to rotate, so that the loading station 17 moves to the position of the pressing station 15, and then stop the conveyor chain 2 to rotate.

[0041] Then, at the pressing station 15, start the hydraulic press 7 and use the tire press head 6 to press the split wheel rim on the pressing station 15 into the inner ring of the tire. The displacement sensor (8) automatically controls the displacement stroke of the tire press head (6). After the pressing is completed, start the conveyor chain 2 to rotate, so that the pressing station 15 moves to the unloading station 14, and then stop the conveyor chain 2 to rotate.

[0042] Finally, at the unloading station 14, the operator tightens the tire bolts 4 with tire nuts (11) in sequence to complete the assembly of the tire assembly 5. Then, the lifting mechanism is started to push the tire assembly 5 out of the corresponding positioning fixture. The conveyor chain 2 is started to rotate again, so that the unloading station 14 moves to the next station. Then the conveyor chain 2 is stopped. The unloading station 14 is equipped with a pusher plate 10 at the corresponding position. The pusher plate 10 rotates with the conveyor chain 2 to push the assembled tire assembly 5 from the unloading station 14 to the transport vehicle.

[0043] In summary, the loading station 17, pressing station 15, and unloading station 14 operate simultaneously. After the operation is completed, the circular conveyor chain 2 drives each station to move forward one station and continue the operation, forming a continuous production line.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any simple modifications, equivalent substitutions, improvements, etc., made within the technical concept of the present utility model should be included within the protection scope of the present utility model.
