Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly, in particular to a front bracket hydraulic lifting device. Background Art

[0002] The front bracket of a car is one of the main frame components of the front of the vehicle. The main function of the front bracket of the car is to support and install the shock absorber. During the assembly process of the car, due to the heavy weight of the front bracket and the irregular structure, mechanical means are required to assist in lifting in order to connect the front bracket to the frame.

[0003] After searching, the prior art was found: Publication No. CN201347146Y discloses a front bracket assembly lifting device, including: a bracket; a cylinder located above the bracket; an automatic inflation device connected to the cylinder, used to automatically inflate the cylinder. Compared with the prior art, the above technical solution has the following advantages: the front bracket assembly lifting device can lift the front bracket through a pneumatically controlled cylinder. During the assembly of the front bracket, it is only necessary to control the lifting and lowering of the cylinder through the automatic inflation device without manual inflation, which can conveniently realize the connection between the hole position of the front bracket and the vehicle body. The pneumatic cylinder has a faster lifting speed, which improves work efficiency and reduces the labor intensity of personnel. In addition, compared with traditional assembly technology, it also saves materials such as jacks and air guns, which can reduce production costs.

[0004] In summary, during the installation or disassembly and maintenance of the front bracket of the automobile, a small crane or jack is mostly used to lift and jack up the front bracket so that the front bracket can be docked with the frame. However, the lifting method of the small crane is single-point lifting, and the balance of the front bracket needs to be adjusted manually. During the lifting process, the balance of the front bracket cannot be guaranteed, and it is easy to fall and require manual intervention and adjustment. In addition, the jack needs to be operated manually, and the work is labor-intensive. Utility Model Content
