Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0021] A method for drilling a small head end of an automobile exhaust manifold, characterized in that it comprises the following steps:

[0022] Step a: Set up a drilling tool on the base, such as figure 1 , 2 , 3, the drilling tool is mainly composed of a horizontal base plate 1, a mounting seat 2, a transmission box 3, a driving cylinder 4, a motor 5, a transmission belt 6, a transmission shaft 7, a connection box 8, a horizontal connection column 9, and a large driving gear 10 , driven pinion 11, drive shaft 12, drill bit 13 and conical connecting bucket 14 etc. constitute. Wherein, the horizontal bottom plate 1 is a rectangular plate, and the horizontal bottom plate 1 is fixed on the base (not shown in the drawings) by T-shaped bolts. A mounting base 2 is fixed on the left side of the horizontal base plate 1, and a transmission box 3 is arranged on th...

Abstract

The invention discloses a method for drilling holes in a small end of an exhaust manifold of an automobile. The method comprises the step a as follows: a drilling tool is arranged on a base, a mounting seat is arranged at the left part of a horizontal bottom plate of the drilling tool, and a transmission case is arranged on the top surface of the mounting seat; a motor is mounted at the top of the transmission case and drives a transmission shaft to rotate; the right end of the transmission shaft is fixedly sleeved with a driving large gear constantly meshed with three driven pinions, and driving shafts are fixedly sleeved with the three driven pinions respectively; the right end of each driving shaft is coaxially connected with a drill bit through a drill bit connecting assembly; a first positioning column is arranged at the left front part of the top surface of an exhaust manifold positioning seat, and a second positioning column is arranged at the right back part of the top surface of the exhaust manifold positioning seat; three front positioning pins are arranged on the right side of the first positioning column from left to right side by side, and three back positioning pins are arranged on the left side of the second positioning column from right to left side by side. With the adoption of the method, three mounting holes can be drilled in the exhaust manifold simultaneously, thus, the position requirement of the three mounting holes can be well guaranteed.

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...
