Small-head end drilling method for automobile exhaust manifold

Abstract

The invention discloses a small-head end drilling method for an automobile exhaust manifold. The small-head end drilling method is characterized by comprising the following steps: step a, a drilling device is arranged on a base, wherein a transmission box is fixedly arranged on the left part of the top surface of a horizontal bottom plate in the drilling device, and a motor is mounted in the transmission box; a drive big gear is fixedly arranged at the right end of a transmission shaft in a sleeving mode, wherein the drive big gear is constantly meshed with three driven small gears which are fixed on a corresponding drive shaft in the sleeveing mode respectively; a slide base is arranged at the right side of a connecting box, and the bottom of the slide base is in sliding fit with a guide rail on the top surface of the horizontal bottom plate, and the slide base can slide left and right under the driving of a pushing motor; an exhaust manifold positioning base is mounted on the top surface of the slide base; a first air cylinder is arranged at the left front side of the exhaust manifold positioning base; a second air cylinder is arranged at the right rear side of the exhaust manifold positioning base; and the two air cylinders are vertically arranged on the top surface of the slide base. The small-head end drilling method can be used for simultaneously drilling three mounting holes in the exhaust manifold, so that the position requirements of the three mounting holes can be guaranteed very well.

Description

technical field [0001] The invention belongs to the field of automobile exhaust manifold processing, in particular to a drilling method for the small head end of the automobile exhaust manifold. Background technique [0002] The exhaust manifold is an important part of the exhaust system of the automobile engine. There are 4 mounting holes on its small head end. The axis lines of the 3 mounting holes are parallel and close to each other. The current processing method is to drill holes one by one. This processing method not only has low processing efficiency, but also cannot reliably guarantee the position of the three holes. Therefore, it is urgent to solve the above technical problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for drilling the small end of the exhaust manifold of an automobile, and it is desired to drill three mounting holes at the small end at the same time. [0004] The technic...
