Chinese patent ZL201210419202.0, a kind of photoelectric encoder of being convenient to installation is disclosed, it comprises shell and pedestal, on pedestal, be rotationally connected blind hole axle, blind hole is the motor shaft that is threaded for axle, blind hole axle head is installed code-disc, as tach signal generating means, outwards carry motor speed signal together with the photoelectric conversion module of enclosure, printed circuit board etc., but this structure connects with segmentation male thread, rotate code-disc rotation precision not high, and the precision of coding disk own is on the low side, be difficult to adapt to high accuracy demand for control.Chinese patent ZL201020685432.8, a kind of photoelectric encoder self adaptation supporting installation device is disclosed, there is certain adaptive ability, in the time of solving to a certain extent rotor operation, there is vertically a difficult problem of damaging photoelectric encoder compared with large vibration, to be tested but radial type support arm steadiness and reliability have.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide that a kind of assembly technology is simple, the low-cost production that realizes bulk article, fixing linkage editor and assembling is simple, maintenance cost is low, can easy adjustment grating disc and the New-type electric machine coding disk assembly technology of the positional precision of luminous point generator.
Object of the present invention is achieved through the following technical solutions: a kind of New-type electric machine coding disk assembly technology, and it comprises the following steps:
S1, first bearing is arranged on the axle journal of machine shaft, then machine shaft is passed from through hole, then bearing is arranged in the bearing mounting hole of electric motor end cap and electric motor end cap is fixed on electric machine stand;
S2, grating disc fixing, is first enclosed within grating disc on locating shaft, then tightens and stop loose bolt and be connected with screwed hole, has realized fixing of grating disc;
Fixing of S3, photocurrent generator, a side of first three U-shapeds being adjusted to pad is all fixed on the bottom of photocurrent generator, again three U-shapeds are adjusted to the opposite side fixed installation pin of pad, then any one installation foot in three installation feet is leaned against to the bottom of cannelure, finally utilize screw through U-shaped adjustment pad and installation foot, to be fixed on electric motor end cap successively, realized the fixing of photocurrent generator;
Debugging after S4, assembling, regulates U-shaped to adjust pad to adjust the level interval of grating disc and photocurrent generator, to complete assembling and setting.
The present invention has the following advantages: (1) the present invention has realized the easy mounting means of grating disc and photocurrent generator, can meet the demand that vehicle is precisely controlled, and can simplify again and manufacture and maintenance difficulty.(2) grating disc of the present invention and photocurrent generator are all installed in electric motor end cap outside, assembly process is considerably less, and photocurrent generator can be adjusted the axial spacing that pad regulates it and grating disc by U-shaped, to regulate the positional precision of grating disc and photocurrent generator, thereby realize the low-cost production of bulk article.(3) due to grating disc and photocurrent generator, all in electric motor end cap outside, install, reduced maintenance cost.
