Background
The rhinestone grinding and polishing machine is equipment for grinding and polishing rhinestone blanks, and adopts the working principle that a rhinestone clamp drives the rhinestone blanks to a grinding and polishing station, and then the rhinestone blanks are ground and polished by controlling the rotation of a grinding and polishing wheel, Chinese patent documents (publication number: CN208100014U, publication date: 2018, 11, 16) disclose a grinding and polishing wheel of the rhinestone grinding and polishing machine and a supporting mechanism thereof, and the rhinestone grinding and polishing machine is provided with the grinding and polishing wheel (1), wherein rotating shafts (3) at two ends of the grinding and polishing wheel (1) are rotatably supported by supporting parts, and the rhinestone grinding and polishing machine is characterized in that: the supporting part includes bearing body (10), hole (14) of bearing body (10) are the bell mouth, the outer lane fixed mounting of bearing body (10) is in bearing housing (6), the both ends of bearing body (10) are connected with end cover (5), install oil blanket (4) between bearing body (10) and end cover (5), the outer lane of bearing body (10) is equipped with oil groove (8), the inside intercommunication of oil groove (8) and bearing body (10), be equipped with on bearing housing (6) oil filler sleeve (7) of aiming at with oil groove (8).
The technical scheme has the following defects: the discovery in the in-service use, when the hole of bearing body set up to the bell mouth, can lead to the atress of bearing unbalanced, and then lead to the bearing to take place to damage easily in the use, greatly shortened the life of bearing, and then the normal work of influence grinding and polishing wheel, often need inspect or change the bearing, be difficult to satisfy user's user demand.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a simple structure is provided, reasonable in design can provide more stable rotation support to the grinding and polishing wheel to effectively improve support bearing's life's rhinestone grinding and polishing machine's grinding and polishing wheel rotation supporting mechanism.
Therefore, the utility model discloses an adopt following scheme to realize:
the grinding and polishing wheel rotating and supporting mechanism of the rhinestone grinding and polishing machine is provided with a grinding and polishing wheel, two ends of the grinding and polishing wheel are outwards provided with rotating shafts in an extending mode, and the rotating shafts are arranged in a conical mode and are characterized in that: still include support bearing, the axis of rotation passes support bearing, support bearing's hole is circular through-hole support bearing with be provided with middle cover between the axis of rotation, the lateral wall of middle cover with support bearing's hole is laminated mutually, the hole of middle cover be with the bell mouth of axis of rotation adaptation.
One end of the middle sleeve abuts against a locking nut, the locking nut is in threaded connection with the rotating shaft, the other end of the middle sleeve abuts against an oil seal, and the oil seal is tightly pressed with the polishing wheel.
One end of the middle sleeve is provided with a leaning step in an outward extending mode, and one end of the supporting bearing is propped against the leaning step.
Cavities which are not communicated with each other are uniformly distributed in the grinding and polishing wheel.
Adopt above-mentioned technical scheme, the utility model discloses an advantage does: set in the middle of setting up through the axis of rotation at the wheel of polishing and supporting bearing, therefore, the hole of supporting bearing can set to conventional centre of a circle through-hole, make supporting bearing when providing the rotation support to the axis of rotation of wheel of polishing, its atress can keep balance, stability when effectively having improved the life of bearing and using, in addition, the hole of middle cover is the bell mouth with the axis of rotation adaptation, so, also can guarantee that the axis of rotation can not take place the shake basically, ensure the stability of wheel pivoted of polishing, further promote the quality of polishing.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is an internal cross-sectional view of the present invention;
fig. 3 is a partially enlarged view of the point a in fig. 2.
Detailed Description
As shown in the drawing, the utility model discloses a brill grinding and polishing machine's grinding and polishing wheel rotation supporting mechanism has grinding and polishing wheel 1, the both ends of grinding and polishing wheel 1 are equipped with axis of rotation 3 outwards with extending, axis of rotation 3 is the toper setting, still include supporting bearing 4, in this embodiment, this supporting bearing 4 is tapered roller bearing, supporting bearing 4 is passed to axis of rotation 3, supporting bearing 4's hole is circular through-hole, be provided with intermediate sleeve 7 between supporting bearing 4 and axis of rotation 3, intermediate sleeve 7's lateral wall is laminated with supporting bearing 4's hole mutually, intermediate sleeve 7's hole is the bell mouth with axis of rotation 3 adaptations. Through set up middle cover 7 between axis of rotation 3 at the wheel of throwing grinding 1 and support bearing 4, therefore, the hole of support bearing 4 can set to conventional centre of a circle through-hole, make support bearing 4 when providing the rotation support to the axis of rotation 3 of the wheel of throwing grinding 1, its atress can keep balance, stability when effectively having improved support bearing 4's life and using, in addition, the hole of middle cover 7 is the bell mouth with axis of rotation 3 adaptation, so, also can guarantee that axis of rotation 3 can not take place the shake basically, ensure the stability of wheel pivoted of throwing grinding, further promote the quality of throwing of grinding. Specifically, one end of the middle sleeve 7 abuts against a locking nut 8, the locking nut 8 is in threaded connection with the rotating shaft 3, the other end of the middle sleeve 7 abuts against an oil seal 5, and the oil seal 5 is tightly pressed against the polishing wheel 1, so that the position stability of the middle sleeve is ensured. One end of the middle sleeve 7 is provided with a leaning step 6 in an outward extending mode, one end of the supporting bearing 4 is propped against the leaning step 6, and the stability of the position of the middle sleeve 7 after being connected with the supporting bearing 4 is guaranteed. In addition, the cavities 2 which are not communicated with each other are uniformly distributed in the grinding and polishing wheel 1, so that the weight of the grinding and polishing wheel is effectively reduced, the power required for driving the grinding and polishing wheel to rotate is reduced, and meanwhile, the cavities 2 are uniformly distributed and not communicated with each other, so that the strength of the whole structure of the grinding and polishing wheel 1 can be ensured.
