Embodiment 1

[0028] A new energy vehicle starter shaft double groove finishing process, comprising the following steps:

[0029] S1. Material treatment: Prepare a round steel, put the round steel into the shot blasting machine, and process the surface of the round steel. The shot blasting time is 10 minutes. After the shot blasting is completed, take out the round steel, and then use sandpaper The surface of the round steel will be polished. After grinding, put the round steel into a container containing pickling agent and pickle to remove the rust on the surface of the round steel. The pickling time is 5 minutes. After washing, wipe the surface of the round steel with a dry cloth;

[0030] S2. Positioning reference: In step S1, after the round steel is processed, use a lathe to turn out the end faces of the two ends of the round steel. After the end faces are turned, drill a center hole at both ends of the round bar to keep the two center holes on the same axis. After the center hole is ...

Embodiment 2

[0044] A new energy vehicle starter shaft double groove finishing process, comprising the following steps:

[0045] S1. Material processing: Prepare a round steel, put the round steel into the shot blasting machine, and process the surface of the round steel. The shot blasting time is 15 minutes. After the shot blasting is completed, take out the round steel, and then use sandpaper The surface of the round steel will be polished. After the grinding is completed, put the round steel into a container containing pickling agent for pickling to remove the rust on the surface of the round steel. The pickling time is 8 minutes. After washing, wipe the surface of the round steel with a dry cloth;

[0046] S2. Positioning reference: In step S1, after the round steel is processed, use a lathe to turn out the end faces of the two ends of the round steel. After the end faces are turned, drill a center hole at both ends of the round bar to keep the two center holes on the same axis. After...

Embodiment 3

[0060] A new energy vehicle starter shaft double groove finishing process, comprising the following steps:

[0061] S1. Material processing: Prepare a round steel, put the round steel into the shot blasting machine, and process the surface of the round steel. The shot blasting time is 13 minutes. After the shot blasting is completed, take out the round steel, and then use sandpaper The surface of the round steel will be polished. After the grinding is completed, put the round steel into a container containing pickling agent for pickling to remove the rust on the surface of the round steel. The pickling time is 7 minutes. After washing, wipe the surface of the round steel with a dry cloth;

[0062] S2. Positioning reference: In step S1, after the round steel is processed, use a lathe to turn out the end faces of the two ends of the round steel. After the end faces are turned, drill a center hole at both ends of the round bar to keep the two center holes on the same axis. After...

Abstract

The invention discloses a double-groove finish machining process for a starter shaft of a new energy automobile. The double-groove finish machining process comprises the steps of material treatment, reference positioning, outer circle rough turning, hardening and tempering, outer circle finish turning, key groove machining and key groove treatment, the end faces of the two ends of round steel areturned through a lathe, and after the end faces are turned, center holes are drilled in the two ends of the round steel. The invention relates to the technical field of automobile starter shaft machining, according to the double-groove finish machining process for the starter shaft of the new energy automobile, the surface of the round steel is treated, shot blasting lasts for 15 min, and after shot blasting is completed, the round steel is taken out, the surface of the round steel is subjected to polishing treatment through abrasive paper; after polishing is completed, the round steel is putinto a vessel containing a pickling agent for pickling, rust on the surface of the round steel is removed, and pickling lasts for 8 min; after acid pickling, the surface of the round steel is wiped clean through dry cloth, the roughness of the surface of the material can be reduced, meanwhile, sand shakeout and core removal are conducted on the surface of the material, and the machining precisionof the material is improved.

Description

technical field [0001] The invention relates to the technical field of automobile starter shaft processing, in particular to a double-groove finishing process for a new energy automobile starter shaft. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with For cars with new technology and new structure, the starter is an indispensable device for new energy vehicles, and the crankshaft on the starter is a crucial part, which plays a role of transmission. [0003] But at present, when the double groove on the starter shaft is processed, the material surface is not pretreated, so that the processing effect is easily affected in the subsequent rough turning and finishing turning process, and no corresponding improvemen...
