Tooling for processing small inclined oil holes in gearboxes by manual bench drilling

Abstract

The invention provides a manual bench drill processing gear box small oblique oil hole tool, which is characterized by comprising a bottom plate and a fixed block, wherein the fixed block is fixedly arranged on the bottom plate; an oblique plane matched with a bench drill base is arranged on the fixed block; an included angle between the oblique plane and the bottom plate is 50 degrees; an oblique through hole is formed in the bottom plate; an included angle between the through hole and the bottom plate is 40 degrees. The bench drill base can be fixed by utilizing the oblique plane on the fixed block, the oblique angles of a bench drill main shaft and a small oblique oil hole are the same at the time, only a bench drill needs to be utilized for processing if processing is required at the time, a milling cutter with the diameter of phi 4 is firstly utilized to process a counter bored hole with the diameter of phi 4, and then a drill head with the diameter of phi 2 is utilized to process a through hole with the diameter of phi 2, so that the influence of human factors on the processing is less during the processing process, and the processing accuracy is greatly improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing tool for a small inclined oil hole of a gear box. Background technique [0002] Such as figure 1 The schematic diagram of the gearbox structure is shown. The small inclined oil hole to be processed is located on the bottom surface of the gearbox. The specifications are φ4 and φ2. For details, see figure 2 and image 3 An enlarged view of the slanted oil hole with an inclination angle of 40°. In the process of processing, because the bench drill is light and flexible in operation, the bench drill is usually used to process the small inclined oil hole. However, because the bench drill is completely operated manually, due to the operator's mistakes, problems such as non-standard, non-compliant, and low precision of the inclined oil hole often occur during the process, and even due to instability during the drilling process, it is very difficult to It is prone t...
