Abstract

The invention discloses a processing and developing process of an intelligent automatic gearbox. The processing and developing process of the intelligent automatic gearbox comprises the following operation steps that S1, a blank is casted; S2, a bottom plane after rough milling is used as a rough reference surface, and during rough milling, a filler block is fixed to a gearbox body blank; S3, a bottom plane after finishing milling is used as the finishing reference surface, and during finishing milling, a filler block is fixed to a gearbox body blank; S4, hole processing is carried out; S5, front steps on the front of the gearbox body blank is subjected to rough milling and semi-finish milling in sequence; S6, the bottom surface of the gearbox body blank is drilled and tapped to make threaded holes; and S7, fine boring is carried out on shaft holes; S8, oiling and sealing are carried out after the cleaning inspection is qualified. The small deformation of a gearbox body under pressurecan be effectively avoided by additionally arranging the filler block on the inner side of the processing surface to effectively ensure the processing accuracy of the gearbox body. The method of simultaneous processing on two sides is adopted to avoid processing accumulation of errors when planes are changed.

Description

technical field

[0001] The invention belongs to the technical field of gearbox processing, and in particular relates to an intelligent automatic gearbox processing and development process. Background technique

[0002] The gearbox is a very important part of the vehicle. It can change the transmission ratio and expand the torque and speed of the driving wheels. In the process of gearbox processing and development, more and more gearboxes are processed by alloy casting. Due to the use of alloy and the high strength of the alloy, the thickness of the alloy gearbox is lighter and thinner than that of the traditional cast iron casing. However, when a gearbox with a low shell thickness is processed by traditional milling technology, it is prone to deformation to varying degrees due to heat dissipation and pressure, thereby affecting the machining accuracy of the gearbox shell.

Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] A processing and development process of an intelligent automatic transmission, comprising the following steps:

[0020] S1: casting blank, casting the gearbox body blank according to the shape parameters of the gearbox. After the casting is cooled, clean the pouring riser and sandblast the surface of the gearbox body blank. After cleaning, the gearbox body blank is inspected by an eddy current flaw detector. flaw detection;

[0021] S2: Determine the rough datum plane...
