Embodiment Construction

[0036] Examples such as figure 1 As shown, an oil pan includes an oil pan body 1, the connection surface between the oil pan body 1 and the upper half of the crankcase is an upper plane 2, and several installation parts for accommodating fixing bolts are arranged on the upper plane 2. Hole 3, positioning pin hole 4 and positioning pin hole 5 are also provided on the upper plane 2, and an oblique oil hole 6 is provided on one side of the oil pan body 1, and the center line of the oblique oil hole 6 forms an acute angle with the upper plane 2 50°, the bottom of the oil pan body 1 is provided with a first inner cavity hole 7 and a second inner cavity hole 8 .

[0037] The processing technology of the oil pan includes the following steps:

[0038] Step 1: Roughly mill the upper plane 2 of the oil pan body 1, and then perform fine milling after rough milling to ensure that the flatness of the upper plane 2 is 0.1mm.

[0039] Step 2, processing positioning pin holes, inner cavity ...

Abstract

The invention relates to a machining process for an inclined oil hole in an oil pan. The oil pan comprises an oil pan body; a surface on which the oil pan body is connected with the upper half part of a crankcase is used as an upper plane; one side of the oil pan body is provided with the inclined oil hole, and an acute angle of 50 DEG is formed between the central line of the inclined oil hole and the upper plane; the upper plane of the oil pan body is provided with a locating pin hole; and the bottom of the oil pan body is provided with an inner cavity hole. The machining process for the inclined oil hole in the oil pan comprises the following steps of: fixing the oil pan body after the upper plane is machined, machining the locating pin hole and the inner cavity hole; then, adjusting the included angle between a machining cutter and the upper plane to 50 DEG; and machining the inclined oil hole. The inclined oil hole, the inner cavity hole and the locating pin hole are machined simultaneously, so that the repeated using times of a reference are reduced, the quality of a product is improved, meanwhile, processes are reduced, the machining efficiency is increased, and the strong guarantee is provided for production.

Description

technical field [0001] The invention relates to an engine oil pan, in particular to a processing technology for an inclined oil hole of the oil pan, and belongs to the field of mechanical technology. Background technique [0002] The oil pan is the lower half of the crankcase, also known as the lower crankcase. As an important part in the engine lubrication system, the oil pan is located at the bottom of the engine. The oil pan is detachably connected to the upper half of the crankcase. Such as figure 1 As shown, the upper plane 2 of the oil pan body 1 is processed with several installation holes 3 for accommodating fixing bolts, and the upper plane 2 is also processed with positioning pin holes 4 and 5 , the oil pan body 1 There is an oblique oil hole 6 on one side, the acute angle formed by the center line of the oblique oil hole 6 and the upper plane 2 is 50°, and the bottom of the oil pan body 1 is provided with a first inner cavity hole 7 and a second inner cavity hole...
