Abstract

The invention discloses a clamp for finish machining of a gearbox shell. The clamp for finish machining of the gearbox shell comprises a base, a transition plate, a connecting plate, a first pressing assemblies and an outer circle holding assembly, wherein the first pressing assemblies and the outer circle holding assembly are connected to the top face of the base, the top face of the transition plate is connected with the window face of the gearbox shell, the bottom face of the transition plate is connected with the top face of the connecting plate, the bottom face of the connecting plate is connected with the base, the top ends of the multiple first pressing assemblies are pressed on the top face of the transition plate, and the outer circle holding assembly is clamped on the outer circle of the gearbox shell. The invention further discloses a clamping method of the clamp. The clamp for finish machining of the gearbox shell has the beneficial effects that the transition plate is adopted for connection, stable clamping and effective clamping and supporting are achieved, the size and precision of finish machining holes of the gearbox shell can be guaranteed, stability and reliability are achieved, and consistency is good.

Description

technical field [0001] The invention relates to a jig, in particular to a jig used for machining a gearbox casing. Background technique [0002] In the prior art, when finishing the gearbox housing (processing some holes and surfaces with high precision requirements), the window faces downward, and the window surface and two positioning pins are used for positioning. There is no suitable pressing position, such as directly pressing the transmission The box shell itself, the workpiece is not clamped tightly, can be shaken manually, and the high-precision hole is easily deformed, and an ellipse will be processed, and the coaxiality of the hole and the parallelism of the axis cannot be guaranteed. [0003] For example, the application number 201910170666.4, a gearbox housing processing jig, is characterized in that: the gearbox housing processing jig includes a bottom plate (1), a vertical plate (2), a rib plate (3), a rectangular opening (4), Special-shaped mouth (5), cylinde...
