Description

Machining process of speed reducer shell and truss robot Technical Field The invention relates to a truss robot, in particular to a truss robot for an automobile differential case. Background The automobile differential shell is a high-strength and precisely cast metal shell part used for wrapping, supporting and driving the internal planetary gear set to rotate in an automobile transmission system so as to realize the differential function of left and right wheels. The oil immersion rust prevention treatment is required to be carried out on the surface of the automobile differential shell in the process of processing the automobile differential shell. In the prior art, oil immersion operation is generally carried out on an automobile differential shell by means of a truss robot. When oil immersion is carried out, the special fixture of the truss robot is used for grabbing the automobile differential shell, the automobile differential shell is accurately and stably immersed into the rust-proof oil groove through a preset motion track, and the automobile differential shell is taken out after oil immersion is completed and is sent to the next working procedure. But current truss robot's special fixture can press from both sides and establish on the automobile differential casing and with automobile differential casing fixed contact, and the contact site is great, so make when carrying out the operation of soaking oil to the automobile differential casing, the automobile differential casing by the position that anchor clamps press from both sides can't contact with fluid, the dead angle of soaking oil is more. Disclosure of Invention The invention aims to provide a truss robot for an automobile differential shell, which aims to solve the problem that oil immersion dead angles are more when the truss robot for the automobile differential shell in the prior art is used for carrying out oil immersion operation on the automobile differential shell.
