Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0022] A method for processing a sliding hole of a cantilever for reverse gear shifting in an automobile, the processing steps of which are as follows:

[0023] a. First, clamp the reverse gear shift cantilever on the worktable of the machining center through the fixture;

[0024] b. Use a φ5.9 drill bit to drill a process hole 3 on the body 1 from top to bottom. After processing, the diameter of the process hole 3 is

[0025] c. Put the drill reamer 4 into the process hole 3 made in step b. When the drill reamer 4 moves from top to bottom, the slide hole 2 is initially drilled, and then the process hole 3 is reamed. During processing The rotating speed of the drill reamer 4 is 1500 rpm, and its feed rate is 100mm / min; after processing, the aperture of the sliding hole 2 is φ5.95, and its surface roughness is 3.2;

[0026] d. Insert the boring tool into t...

Abstract

The invention discloses a machining method for a slide hole in an automotive reverse-gear and gear-shift suspension arm. The machining method comprises the machining steps of: a. clamping the reverse-gear and gear-shift suspension arm on a machining centre at first; b. drilling a process hole in a body by adopting a drill bit having a diameter phi being 5.9; c. stretching a drilling-reaming tool in the process hole formed in the step b, expanding the process hole at first and then primarily drilling a slide hole by the drilling-reaming tool when the drilling-reaming tool moves from top to bottom; d. stretching a boring tool in the process hole formed in the step c, and roughly boring the slide hole formed in the step c by the boring tool while moving downwards; and e. finely boring the roughly-bored slide hole by the boring tool which is used in the step d while moving upwards, wherein the surface roughness of the finely-bored slide hole is 1.6. By using the machining method for machining the slide hole of the automotive reverse-gear and gear-shift suspension arm, the surface roughness of the slide hole can be well controlled to be less than 1.6, so that the requirements of clients on the surface roughness can be reliably met; and moreover, the machining cost is greatly reduced simultaneously.

Description

technical field [0001] The invention belongs to a processing method of an automobile reverse shifting cantilever, in particular to a processing method of a sliding hole of an automobile reverse shifting cantilever. Background technique [0002] As we all know, the reverse gear shift cantilever (such as figure 1 Shown) is one of important parts of automobile reverse gear system, has sliding hole 2 on the body 1 of cantilever, steel ball is housed in this sliding hole 2 during assembly. The size requirement of the aperture of the sliding hole 2 is And the surface roughness of the sliding hole 2 is required to be controlled at 1.6. At present, the above-mentioned sliding hole 2 is generally processed on the machining center by means of drilling, expanding, and twisting. The specific processing steps are as follows: [0003] a. Preliminarily drill the upper process hole 3 and the above-mentioned sliding hole 2 with a φ5.9 drill bit at the same time; [0004] b. Reaming the ...
