Description
Technical Field
The invention belongs to the field of equipment manufacturing, relates to a dumper casting technology, and particularly relates to a combined machining method for a frame and a planet carrier of a mining dumper.
Background
The mining dump truck is one of important key devices in the transportation process of a surface mine, is responsible for the main transportation task of mining on mines, and is widely applied to coal mines, iron mines and other mine environments. As one of important parts on an electric drive dump truck, a wheel reduction gear plays an important role, and with the trend of upsizing a mining dump truck, the requirement for the reliability of the wheel reduction gear is higher and higher. At present, the dumper for large-scale transportation mainly adopts imported parts, wherein a main shaft of the 230-ton dumper is required to bear the dead weight of the whole dumper and the weight of about 400 tons of cargos, and the existing casting mode is to assemble and use a machine base and a planet carrier after being processed in a split mode, so that the precision of products is greatly reduced. The planet speed reduction requires high precision, and assembly after split machining brings more troubles and product quality defects.
Disclosure of Invention
In order to solve the problems existing in the assembly and use of the split type processed frame and the planetary carrier of the wheel-side speed reducer of the conventional electric drive dumper, the invention provides a combined machining method of the frame and the planetary carrier of the mining dumper, which meets the aim of simultaneously processing the combined parts of parts and components, avoids the position degree difference caused by the respective processing of the parts, ensures the coaxiality and the precision of the parts and greatly improves the processing speed.
The technical scheme adopted by the invention for solving the technical problem is as follows: a combined machining method for a frame and a planet carrier of a mining dump truck comprises the following steps:
step 1: processing the combined part of the frame and the planet carrier;
and 2, step: correspondingly connecting the combined part of the frame with the combined part of the planet carrier;
and 3, step 3: and carrying out metal cutting on the combined frame and the planet carrier.
As a further embodiment of the present invention, the step 1 specifically comprises:
and processing a combination hole a at the end surface of one side of the rack, and processing a combination hole b at the end surface of one side of the planet carrier, so that the hole diameters of the combination hole a and the combination hole b are the same.
As a further embodiment of the present invention, step 2 specifically is:
and the combination hole a corresponds to the combination hole b, and a connecting piece is arranged in the combination hole a and the combination hole b, so that the end surface of the frame is attached to the end surface of the planet carrier.
As a further embodiment of the invention, a locking hole is formed in the middle of the connecting member, and a locking member is arranged in the locking hole to lock the position of the connecting member in the combination hole a and the combination hole b.
As a further embodiment of the invention, the connecting member is an expansion pin and the locking member is an expansion bolt.
The beneficial effects of the invention include: the invention solves the defect of low split machining precision by the design of combined machining of the frame and the planet carrier, combines two independent parts and then carries out metal cutting by the combined design, meets the purpose of simultaneously machining the parts by combining the parts and the components, ensures the coaxiality and the precision of the parts, avoids the position difference caused by the respective machining of the parts, and greatly improves the machining speed.
