Problems solved by technology

[0005] 1. Use the extended right-angle milling head for processing, the rigidity of the milling head is relatively poor, and the vibration between the milling head and the machine tool is serious
[0006] 2. The force of the three-sided milling cutter is relatively large, and the cutter cuts intermittently, the blade is easy to chip, and the milling head is easily damaged
[0007] 3. Affected by the vibration of the milling head, the machine tool and the large force on the three-sided milling cutter, the tool feeds only 4mm each time, and the efficiency is low
[0008] 4. The margin of each part of the oil tank is not uniform, and the processing time and space are many, which wastes processing time
[0009] 5. The machining allowance is relatively large, and each feed is 4mm, so it needs to go through multiple knives for processing, which leads to long processing time and low efficiency

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] like Figure 1 to Figure 3 As shown in , a large diesel engine block main shaft hole oil groove processing method, such as figure 1 As shown in , the following grooves are processed in the middle of the surface of the main shaft hole 2 on one side of the body 1. Taking the groove with a width of 25mm and a maximum depth of 40mm as an example, the specific steps are as follows:

[0026] (1) Use a short and rigid ball end mill to remove most of the allowance first.

[0027] First use a D25 short ball end milling cutter 3 with good rigidity, the cutting amount of each cutter is 15mm, and the ...

Abstract

The invention relates to a machining method for a spindle hole oil groove of a large diesel engine body. The method comprises the following implementation steps that most margins are removed with a short ball milling cutter with the good rigidity; margins of the interference portion are removed with a long ball milling cutter; remaining margins are removed for one time with a three-edge milling cutter, and the groove is finally obtained. The machining method has the advantages that the machining time is short, the machining efficiency is high, the cutters are not prone to be tipped, the using effect is good, and the life is long.

Description

technical field [0001] The invention belongs to the technical field of machine body oil groove processing methods, and in particular relates to a large diesel engine body main shaft hole oil groove processing method. Background technique [0002] The main shaft hole oil groove of a large diesel engine body refers to the groove located in the middle of the main shaft hole surface on one side of the body. When the engine is working, high-pressure lubricating oil is stored to lubricate the crankshaft. [0003] Because the above-mentioned oil tank is located inside the machine body, it generally has the problems of large machining allowance, difficult machining, and time-consuming and labor-intensive problems. [0004] In the current domestic and foreign technologies, the processing of the oil groove of the main shaft hole of the large diesel engine body is usually carried out on the floor boring and milling machining center or the gantry pentahedron machining center, using the ...
