Description
Technical Field
The utility model belongs to the technical field of the vehicle assembly technique and specifically relates to a lightweight frame axle head stop device for wheel assembly.
Background
The turning of a wheel assembly matched with a chassis of the ultra-heavy special off-road vehicle needs to protect the front end thread of an axle tube; meanwhile, the installation depth of the input shaft is limited, and extrusion damage in the oil seal installation process is prevented. The original shaft end is limited by turning an inner hole and a thread by round steel and adopting an end cover plate plugging structure; the use process has the defects of large volume, heavy weight, difficult inspection, easy deformation in welding and inconvenient disassembly and assembly by one hand. When the wheels are assembled in batch, the problem of thread damage in the overturning process often occurs; after the original shaft end is adopted for protection, the problems of low installation efficiency and high labor intensity exist, and the production efficiency is seriously restricted.

Detailed Description
The technical solution of the present invention is clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in figure 1 a lightweight frame axle head stop device for wheel assembly, including base 1, connecting rod 2, stopper 3 and protection casing 4, base 1 is equipped with the internal thread, and base 1 establishes screwed one side and 6 threaded connection of central siphon of wheel assembly, and the base center is equipped with through-hole 5, the aperture of through-hole 5 is greater than the external diameter of protection casing 3, the one end of connecting rod 2 and base 1's opposite side threaded connection, the other end and 3 fixed connection of stopper, base 1, stopper 3 and the coaxial setting of protection casing 4, protection casing 4 passes through-hole 5, and the end of protection casing 4 supports and leans on stopper 3, the end and the 4 threaded connection of protection casing of input shaft 7 of wheel assembly.
In this embodiment, the connecting rod 2 is the L type and is equipped with three groups at least, and multiunit connecting rod 2 evenly sets up along the circumference of base 1.
In this embodiment, the protection cover 4 is a hollow stepped shaft, and the upper end and the lower end of the protection cover 4 are open.
In this embodiment, the limiting block 3 is a hexagonal nut.
The working principle of the shaft end limiting device provided by the embodiment of the application is as follows: firstly, the central siphon 6 and the base 1 threaded connection of wheel assembly to place on the workstation, wherein, the stopper 3 that adopts the hexagonal head nut can realize that pneumatic tool assists and screws up, and is efficient. Secondly, connecting the protective cover 4 with the input shaft 7 through threads, and hoisting the protective cover to a workbench; then, the input shaft 7 is inserted into the inner hole of the shaft tube 6 until contacting with the bottom limiting block 3; then, after the input shaft 7 is fixed, the assembly is taken down from the workbench, turned over by 180 degrees, taken down from the limiting device and assembled, as shown in fig. 2.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
