DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a hub unit assembly device, including an assembly device main body 1, on which there is an installation frame 9. The installation frame 9 is evenly and spacedly installed with conveying rollers 10, and between the conveying rollers 10, there are symmetrically arranged limiting rollers 11 respectively. On both sides of the long side of the installation frame 9, there are symmetrically connected support side plates 16. Above the support side plates 16, there are successively arranged a first assembly chamber 3, a first detection chamber 4, a second assembly chamber 5, a second detection chamber 6, a third assembly chamber 7, and a third detection chamber 8 from left to right. At the lower parts of the first assembly chamber 3, the second assembly chamber 5, and the third assembly chamber 7, there are evenly and spacedly arranged lifting hydraulic cylinders 13, and the lifting hydraulic cylinders 13 are vertically arranged between the conveying rollers 10. With this structure, in the first assembly chamber 3, the second assembly chamber 5, and the third assembly chamber 7, there are respectively installed devices for press-fitting of hub units, fixing of sealing rings, and fixing of bolts, so that the hub units are successively assembled. After each assembly is completed, visual inspection is respectively carried out through the first detection chamber 4, the second detection chamber 6, and the third detection chamber 8 to ensure the qualification and accuracy of the assembly position, and unqualified components can be quickly detected for timely return and reinstallation. Above the conveying rollers 10, there is a hub assembly positioning table 2, which is clamped between the limiting rollers 11. At the lower ends of the limiting rollers 11 on the same side, there is a common rotating connection with a limiting roller mounting plate 12, and the limiting roller mounting plate 12 is arranged on the installation frame 9. With this structure, the limiting rollers 11 can limit the side of the hub assembly positioning table 2 to ensure the stable conveyance of the hub assembly positioning table 2 on the conveying rollers 10. The conveying rollers 10 are an existing roller conveying structure, and the limiting roller mounting plate 12 can move and adjust the limiting rollers 11 on the same side to better clamp the hub assembly positioning table 2. The hub assembly positioning table 2 is used for the assembly positioning of the hub unit, and the hub unit is clamped and positioned for assembly through the clamping member 202 for operations such as press-fitting, fixing of sealing rings, and fixing of bolts. In the middle of the upper end of the hub assembly positioning table 2, there is a central positioning column 203. The bottom movable end of the lifting hydraulic cylinder 13 is screwed and fixed on the installation frame 9, and the upper movable end of the lifting hydraulic cylinder 13 is also screwed and fixed with a clamping seat 14. With this structure, the clamping seat 14 is lifted by the lifting hydraulic cylinder 13. The lifting hydraulic cylinder 13 is arranged between the conveying rollers 10, so that the lifting of the lifting hydraulic cylinder 13 is not hindered. The clamping seat 14 is a conical frustum structure, and the clamping seat 14 is in clamping cooperation with the bottom of the hub assembly positioning table 2. When the lifting hydraulic cylinder 13 lifts the clamping seat 14, the clamping seat 14 can be clamped at the bottom of the hub assembly positioning table 2 and drive the hub assembly positioning table 2 to rise, so that the hub unit clamped and fixed on the hub assembly positioning table 2 can be respectively moved into the first assembly chamber 3, the second assembly chamber 5, and the third assembly chamber 7 for assembly, and the safety protection during assembly is ensured. On the hub assembly positioning table 2, there are evenly and spacedly arranged limiting grooves 201 centered on the central positioning column 203,Moreover, clamping members 202 are installed in the limit slots 201, and infrared sensors 15 which cooperate with each other are respectively installed on the clamping member 202 close to the support side plate 16 and the support side plate 16. The length of the mounting frame 9 is longer than that of the support side plate 16, and the infrared sensors 15 installed on the support side plate 16 correspond to the positions of the first assembly chamber 3, the second assembly chamber 5, and the third detection chamber 8 respectively. This structure enables the positions of the front and rear ends of the mounting frame 9 to be respectively used for the loading and unloading of the hub unit. The infrared sensors 15 can be used to detect the position of the hub assembly positioning table 2. After the hub assembly positioning table 2 moves to the positions below the first assembly chamber 3, the second assembly chamber 5, and the third assembly chamber 7 respectively, by connecting the signal of the infrared sensor 15 with the servo motor for driving the conveying roller 10, the conveying of the hub assembly positioning table 2 can be stopped, thereby realizing the positioning of the hub assembly positioning table 2.

[0018] Working principle: When using this hub unit assembly device, first place the hub unit on the hub assembly positioning table 2. The central positioning column 203 plays a role in central positioning. The clamping member 202 moves in the limit slot 201 to clamp and fasten the hub unit. The conveying roller 10 is conveyed under the drive of the servo motor with the installation and positioning of the mounting frame 9, realizing the movement of the hub assembly positioning table 2. The limit roller 11 plays a role in laterally limiting the hub assembly positioning table 2 during the movement process. The limit roller mounting plate 12 plays a role in uniformly fixing the limit rollers 11 on the same side. The support side plate 16 enables the first assembly chamber 3, the second assembly chamber 5, the third assembly chamber 7, the first detection chamber 4, the second detection chamber 6, and the third detection chamber 8 to be stably installed above the mounting frame 9 respectively. When the hub assembly positioning table 2 moves to the positions below the first assembly chamber 3, the second assembly chamber 5, and the third assembly chamber 7 in sequence, the infrared sensor 15 senses the position of the hub assembly positioning table 2, stopping the conveying roller 10. The lifting hydraulic cylinder 13 drives the clamping seat 14 to rise, enabling the clamping seat 14 to be inserted into the bottom of the hub assembly positioning table 2, and then pushing the hub assembly positioning table 2 upward until the hub unit enters the first assembly chamber 3, the second assembly chamber 5, and the third assembly chamber 7 respectively, and respectively performing press-fitting, seal fixing, and bolt fixing of the hub unit. After the assembly is completed, then lower the hub assembly positioning table 2 and let it fall onto the conveying roller 10. When the hub assembly positioning table 2 passes through the first detection chamber 4, the second detection chamber 6, and the third detection chamber 8 during the conveying process, quality inspection and processing of the press-fitting, seal fixing, and bolt assembly are respectively carried out, completing the high-quality assembly operation of the assembly device main body 1, thereby completing a series of work.

[0019] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
