Problems solved by technology

[0002] Among diesel engine parts, there is a kind of spacer part, which has a relatively simple structure. Due to the large machining error of machine tool precision and alignment processing method, only some parts barely meet the coaxiality requirements. Currently, they are processed on vertical lathes. Due to the influence of precision and part structure, the quality of mass-produced parts cannot be guaranteed, resulting in the failure of normal production of many batches of parts, which seriously affects the production node of diesel engines

Embodiment 1

[0031] see Figure 1-6 As shown, a processing method to ensure the coaxiality of spacer parts includes the following steps:

[0032] Step 1: Install fixture A on the boring machine workbench, press fixture A after correct positioning, and then install the workpiece on fixture A and press it with a pressure plate; fixture A includes angle iron 1 for connecting the spacer and the machine tool , the lower plane of the angle iron 1 is connected and fixed to the boring machine table, the spacer is fixed on the side of the angle iron 1 for positioning, and the spacer is fixed with four pressure plates 3, and the pressure plate 3 adopts four supports 2 for support, Four stud bolts 4 and four compression nuts 5 are used to compress the pressure plate and the spacer ring. The function of the fastening nut 8 is to fix the support 2 and the stud bolt 4 on the angle iron 1; There is a large hole in the middle of the angle iron 1, and the tool can pass through the back boring hole from th...

Embodiment 2

[0038] During back-boring processing, because the boring bar is in the hole, ordinary inner micrometers and inner micrometers cannot be used for measurement, and only special measuring tools and inspection tools D can be used for measurement; when machining larger holes, because the boring tool cannot be used in the hole Exit, the conventional inner diameter micrometer or dial gauge interferes with the boring tool when measuring the inner diameter size, and cannot measure the size of the trial machining hole. Use the inspection tool D that can cross the boring tool to measure the hole diameter, so as to adjust the fine boring head to meet the processing requirements.

Description

technical field [0001] The invention relates to a processing method for ensuring the coaxiality, in particular to a processing method for ensuring the coaxiality of spacer parts, and belongs to the technical field of improving the coaxiality precision. Background technique [0002] Among diesel engine parts, there is a kind of spacer part, which has a relatively simple structure. Due to the large machining error of machine tool precision and alignment processing method, only some parts barely meet the coaxiality requirements. Currently, they are processed on vertical lathes. Due to the influence of precision and part structure, the quality of mass-produced parts cannot be guaranteed, resulting in the failure of normal production of many batches of parts, which seriously affects the production node of diesel engines. Therefore, in view of the above problems, a processing method to ensure the coaxiality of spacer parts is proposed. Contents of the invention [0003] The obj...
