Abstract
The utility model discloses a grinding head motor structure for eliminating axial float, comprising a motor main body, wherein the end of the motor main body is provided with an end cover, the end cover is internally provided with a bearing room, the bearing room is internally provided with a bearing, the bearing room is internally provided with an axis through hole, the inner wall of the axis through hole is provided with an inner thread, the axis through hole is further internally provided with a positioning cover for pressing the bearing, the outer side of the positioning cover is provided with an outer thread which is correspondingly matched with the inner thread of the axis through hole, the bearing room of a front end cover or a back end cover of the grinding head motor structure is internally provided with the axis through hole, the inner wall of the axis through hole is provided with the inner thread, and the relevant overlapped dimensional tolerance between a bearing outer ring on a positioning cover adjusting rotor and the end cover of a base is configured to be zero, so that the error between each part and the machining tolerance can be eliminated, and the flaw of the glass ground by a glass edge grinding machine can be avoided.
Description
Technical field
The utility model relates to a kind of grinding head motor structure.
Background technology
In the glass deep processing, glass edge-grinding machine is one type of important process equipment.In the glass edging process equipment, generally adopt motor need make by it after, directly load onto emery wheel on its shaft extension, become grinding head motor.Common electric machine generally allows 0.50 ㎜ axial endplay position, and grinding head motor can only have the 0.02 ㎜ play position of (being equivalent to 1/25 times of common electric machine) because of its instructions for use.Surpass 0.02 ㎜ play position, flaw just occurs at machined surface.In order to eliminate the excessive play of grinding head motor, generally adopt wave washer to eliminate in the prior art with elastic force, perhaps adopt shaft block ring to eliminate the gap.If a kind of method before adopting,, can produce axial endplay when the cutting force of emery wheel during greater than wave washer elastic force; If adopt a kind of method in back, processing axial dimension tolerance will guarantee that in 0.02 ㎜ scope general lathe is not accomplished, promptly uses high precision machine tool to accomplish, load onto shaft block ring after, bearing receives axial force transmission behind shaft block ring, its play also can surpass 0.02 ㎜.Axial endplay how to eliminate grinding head motor is the technical problem that needs to be resolved hurrily.
The utility model content
The technical problem that the utility model will solve provides a kind of grinding head motor structure of effective elimination axial endplay.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of grinding head motor structure of eliminating axial endplay comprises the motor main body, and the motor body end is equipped with end cap; Be provided with bearing chamber in the end cap; The bearing of accepting rotor is installed in the bearing chamber, is provided with axis through bore in the said bearing chamber, the inwall of axis through bore is provided with internal thread; Also be provided with the positioning sleeve that is used to compress bearing in the axis through bore, this positioning sleeve outside has the external screw thread with the internal thread corresponding matching of axis through bore.
As the improvement of technique scheme, evagination has locking nut in the positioning sleeve part threaded engagement of bearing chamber.
As the improvement of technique scheme, the outer end of said positioning sleeve is provided with some apertures of being convenient to install.
The beneficial effect of the utility model is: be provided with axis through bore in the front end housing of this grinding head motor structure or the bearing room of back top cover; At the axis through bore inwall internal thread is set; The relevant stack with the support end cap of the bearing outer ring dimensional tolerance that the configuration positioning sleeve is regulated on the rotor is zero; Thereby eliminated the error of each spare and accessory parts and machining tolerance, guaranteed that flaw does not appear in glass edge-grinding machine grinding glass.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the enlarged diagram at A place among Fig. 1.
Embodiment
See figures.1.and.2; A kind of grinding head motor structure of eliminating axial endplay of the utility model comprises motor main body 1, and motor main body 1 end is equipped with end cap 2; Be provided with bearing chamber 3 in the end cap 2; The bearing 4 of accepting rotor is installed in the bearing chamber 3, is provided with axis through bore 30 in the said bearing chamber 3, the inwall of axis through bore 30 is provided with internal thread; Also be provided with the positioning sleeve 5 that is used to compress bearing 4 in the bearing chamber 3, these positioning sleeve 5 outsides have the external screw thread with the internal thread corresponding matching of axis through bore 30.When grinding head motor is installed; Utilize specific purpose tool that positioning sleeve 5 is tightened or unscrewed; Regulating the relevant stack with the support end cap of epitrochanterian bearing outer ring dimensional tolerance is zero, eliminates the error of each spare and accessory parts and machining tolerance, just can guarantee that flaw does not appear in glass edge-grinding machine grinding glass.
In the present embodiment, evagination has locking nut 6 in the positioning sleeve 5 part threaded engagement of bearing chamber 3, after positioning sleeve 5 compresses bearing 4, further with positioning sleeve 5 lockings, can prevent the new axial endplay of positioning sleeve 5 loosening generations through locking nut 6.
The outer end of said positioning sleeve 5 is provided with some apertures 7, is convenient to adopt specific purpose tool positioning sleeve 5 to be tightened or unscrewed, more convenient operation.
The above is merely the preferential execution mode of the utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection range of the utility model.
