Horizontal Machining Center for Truck Rear Axle Reducer Housing and Its Application Method

Abstract

The invention provides a truck rear axle reducer shell horizontal machining center comprising an operation case. The middle of the operation case is provided with a fixing seat, the fixing seat is provided with a cube-shaped case body composed of an upper plate, a base, a left plate, a right plate and a front plate in a welded manner. The front plate of the case body is provided with a round hole, arc assembling tables are welded to the upper and lower sides of the round hole, the middle of the case body is provided with a press plate, machining holes are formed in the left and right plates of the case body and the press plate in the case body integrally, and a reducer shell is inserted in the round hole of the front plate to press the press plate to the shell; fin plates are located on two sides of the press plate, are pressed to a support plate and are exposed to the machining holes; a boss of the reducer shell is fitted to the assembling tables tightly. The truck rear axle reducer shell horizontal machining center is simple in structure and convenient to use and is particularly used for clamping and fixing the truck rear axle reducer shell, machining and drilling of the machining center are benefited, producing efficiency is improved, and the scrape rate is decreased.

Description

Technical field: [0001] The invention relates to the technical field of machinery for processing auto parts, in particular to a horizontal machining center for a rear axle reducer housing of a truck and a method for using the same. Background technique: [0002] The reducer housing of the rear axle of the truck, such as the rear axle reducer housing of the Steyr series, has a structure such as figure 1 Shown is a structural schematic diagram of the reducer housing of the rear axle of the truck. One side of the housing is provided with an interface 1, and the other side is provided with two wing plates 3, the middle part of the wing plate 3 is provided with a shaft hole 2, the end of the wing plate 3 is also provided with an interface, and the middle part of the housing is provided with a boss 4, The boss surrounds the outer wall of the housing, and the housing 4 is provided with several assembly openings 5 ​​. For the processing of this kind of reducer housing, after the h...

Problems solved by technology

For the step of processing the shaft hole, due to the irregular shape of the shell, it is difficult to fix. Usually, a clamping device is inserted along the middle of the two wing plates, and one wing plate is clamped to process a single shaft hole, and then the shell is removed. Then clamp another screw hole for processing. This processing method has low production efficiency, and once the positioning is not accurate, it is easy to cause deviation of the shaft hole, resulting in the shell becoming a waste product with a high waste rate.
