[0038] The following is combined with Figures 1 to 2 This application is described in further detail.
[0039] The embodiment of the present application discloses a novel hanger for assembling axle shafts.
[0040] Reference Figures 1 to 2 A novel lifting device for half-axle assembly includes: a connecting block 1, a first tooling, a hanging rod 3, a limiting sleeve 6, a second tooling, a connecting rod 9, and a lifting ring 10.
[0041] The bottom of the connecting block 1 is provided with a first tooling for supporting and positioning the axis diameter of the half shaft.
[0042] The first tooling can be a hook 2, which has a simple structure and low cost, can hook the half-shaft diameter, and is easy to operate. A threaded hole A is provided at the bottom of the connecting block 1, and an external thread A is provided at the top of the hook 2. The top of the hook 2 is connected to the connecting block 1 through a thread, and the hook 2 is connected to the connecting block 1 through a thread. This connection method is simple and reliable, and is convenient to disassemble and assemble, and is also convenient for replacing the hook 2, and has strong practicality.
[0043] The first fixture can also be a fixture, which can be a fixture fixture designed according to the half-shaft structure, and can be an annular fixture that can clamp the half-shaft shaft portion, and the support and positioning of the half-shaft is more stable and reliable. A threaded hole B is provided at the bottom of the connecting block 1, and an external thread B is provided at the top of the fixture. The top of the fixture is connected to the connecting block 1 through a threaded connection, and the fixture is connected to the connecting block 1 through a threaded connection. This connection method is simple and reliable, and is convenient to disassemble and assemble, and is also convenient for the replacement of the fixture, and has strong practicality.
[0044] The hanging rod 3 is arranged transversely and connected to the connecting block 1 .
[0045] A connecting hole 4 is horizontally penetrated on the connecting block 1, and one end of the hanging rod 3 is designed with a reduced diameter, and the end passes through the connecting hole 4. The hanging rod 3 cooperates with the hole axis of the connecting hole 4. Through the hole-axis cooperation, the connection method is simple, the hanging rod 3 can be rotated, and it is easy to use.
[0046] A pin hole A5 is provided at one end of the hanging rod 3 passing through the connecting hole 4, and a limiting sleeve 6 is provided at the end, and a pin hole B7 is provided on the limiting sleeve 6. The pin hole A5 is aligned with the pin hole B7, and then a split pin is inserted. The axial movement of the hanging rod 3 in the connecting hole 4 is limited by reducing the diameter of one end of the hanging rod 3 and setting the limiting sleeve 6, so as to prevent the hanging rod 3 from axially moving randomly, which is beneficial to improving the hoisting stability. The limiting sleeve 6 and the hanging rod 3 are limited by the split pin, so as to prevent the limiting sleeve 6 from falling off.
[0047] The second tooling is arranged at the other end of the hanging rod 3, and is used for supporting and positioning the half-shaft flange.
[0048] The second tooling is a hook 8, which is an integrated structure designed with the other end of the hook 8 and the hanging rod 3. The second tooling includes a hook 8, which can be inserted into the flange hole of the half-axle through the bent hook of the hook 8 to provide auxiliary support and positioning for the half-axle, and play a supporting and balancing role. It is highly practical and can ensure the stability and balance of the lifting, transportation and assembly of the half-axle.
[0049] The connecting rod 9 is arranged at the top of the connecting block 1, and is designed as an integral structure with the connecting block 1. A threaded hole C is provided at the top of the connecting rod 9, and the lifting ring 10 is a lifting ring 10 screw, which is threadedly matched with the threaded hole C.

[0050] Through the setting of the first tooling, the axis diameter of the half-axle can be supported and positioned. Through the setting of the second tooling, in cooperation with the hanging rod 3, the half-axle flange and the flange hole can be supported and positioned. The setting of the lifting ring 10 facilitates the use of cranes, cranes and other equipment for lifting and transportation, ensuring the stability and balance of the half-axle during lifting, transportation and assembly.
[0051] When in use, the operator holds the hook 8 and inserts its bent hook into the hole of the half-shaft flange to preliminarily position the hoist and the half-shaft; the operator holds the half-shaft flange to pull out the half-shaft until half of the half-shaft bearing is exposed, and then rotates the hook 2 to hook the half-shaft shaft diameter. When using a clamp, clamp the half-shaft shaft, and the operator operates the KPK (crane) to lift the half-shaft for transportation and assembly.
[0052] The utility model axle half-axle lifting tool utilizes the support and positioning of the half-axle flange to ensure the positioning and stability of the half-axle during the whole lifting process, reduce the labor intensity of workers, and ensure that the quality and state of parts are not affected by the manual handling process during mass production.
[0053] The lifting is carried out through two lifting points, namely the flange and the half-axle shaft. The lifting process is balanced, and a rotatable hook 2 or a clamp is used to lift the half-axle shaft. This ensures that the half-axle lifting process is smooth and avoids slippage and falling off during the lifting and rotation of the half-axle. It has a certain protective effect on the operator's assembly process and reduces the safety risk of worker injury during the assembly process. The operation is more convenient, no manual handling is required, and the safety is higher.
