DETAILED DESCRIPTION

[0019] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 8 It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0020] This embodiment provides an adjustable bearing ring grinding and feeding device, as shown in the attached Figure 1-8 As shown, it includes a placement platform 1 and a sliding frame 2 for centrally placing bearing rings. The top of the placement platform 1 is a disc that can hold bearing rings. The interior of the placement platform 1 is provided with a turntable mechanism for driving the bearing rings to move. The turntable mechanism includes a first motor 5 and a turntable 6. The first motor 5 is fixedly mounted at the center of the lower surface of the placement platform 1 and the drive shaft is passed through the interior of the placement platform 1. The turntable 6 is rotatably connected to the interior of the placement platform 1 and the center of its lower surface is connected to the drive shaft of the first motor 5 through a spline. The first motor 5 can drive the turntable 6 to rotate, thereby causing the turntable 6 to drive the bearing rings placed above it to rotate.

[0021] An opening for passing the bearing ring is provided on the side of the placement platform 1, and a guide plate 12 that can be pulled outward is provided on one side of the opening of the placement platform 1. The bent portion of the guide plate 12 overlaps the upper surface of the turntable 6. When the turntable 6 drives the bearing ring to rotate, the bearing ring in contact with the guide plate 12 will slide outward from the opening along the guide plate 12 under the push of the turntable 6 and the guiding action of the guide plate 12, and then slide onto the sliding frame 2.

[0022] A leveling mechanism for moving the bearing ring is provided on the top of the placing platform 1, and the leveling mechanism includes a cross-shaped mounting frame 7, a movable frame 8 and a paddle 9. The cross-shaped mounting frame 7 is fixedly mounted on the top of the placing platform 1 and the movable frame 8 is arranged below the cross-shaped mounting frame 7. An insertion rod 10 is fixedly connected to the upper surface of the movable frame 8, and a sleeve rod 11 is fixedly connected to the upper surface of the cross-shaped mounting frame 7 at a position corresponding to the insertion rod 10. The insertion rod 10 is inserted into the corresponding sleeve rod 11 and can move up and down inside it. The number of paddles 9 is several and several paddles 9 are evenly and equidistantly fixedly connected to the lower surface of the movable frame 8. The paddle 9 is made of elastic plastic or rubber material, which can move the bearing ring and can also be reset when subjected to a large external force. The insertion rod 10 at the center of the movable frame 8 is inserted into the center of the upper surface of the cross-shaped mounting frame 7. The bottom thread of the side of the sleeve rod 11 is penetrated by a clamping bolt which can clamp the insertion rod 10. Tightening the clamping bolt can fix the position of the insertion rod 10, so that the height of the movable frame 8 and the paddle 9 can be adjusted conveniently according to the end face thickness of the bearing ring. When the turntable 6 drives the bearing ring to rotate, the bearing ring will pass under multiple paddles 9. When there are two or more bearing rings stacked on each other or one side of one bearing ring is leaning against another bearing ring, because the spacing between the bottom end of the paddle 9 and the turntable 6 and the thickness of the bearing ring are adapted, the bearing ring in a flat state can just pass under the paddle 9, and the stacked bearing rings will separate from each other under the obstruction of the paddle 9, so that all the bearing rings can be placed flat on the turntable 6, which is convenient for automatic adjustment of the state of the bearing ring.

[0023] The sliding frame 2 is arranged at the opening of the placement platform 1, and a sensor 13 capable of sensing the bearing ring is fixedly installed on the side of the sliding frame 2. The sensor 13 can sense the bearing ring passing by, so as to facilitate the counting of the bearing ring. The upper surface of the sliding frame 2 is provided with an adjustment mechanism that can adjust the spacing and make the bearing ring stand up. The adjustment mechanism includes a special-shaped adjustment plate 14 that can stand up the bearing ring, a slider 15, a positioning block 16 and a fixing bolt 17. The bottom of the special-shaped adjustment plate 14 is fixedly connected with the slider 15 and is slidably connected to the upper surface of the sliding frame 2 through the slider 15. The end of the special-shaped adjustment plate 14 close to the placement platform 1 is in a gradually shrinking inclined plate state, and the end away from the placement platform 1 is parallel to the side plate of the sliding frame 2. When the bearing ring sliding down passes through the tapered inclined plate part of the special-shaped adjustment plate 14, it will be adjusted from a flat state to a vertical state under the guidance of the tapered inclined plate. When the bearing ring moves to the bottom of the special-shaped adjustment plate 14, it is in a vertical state, so that it can roll downward. The positioning block 16 is fixedly connected to the middle part of the lower surface of the special-shaped adjustment plate 14 and slidably connected to the bottom of the sliding frame 2. The lower surface of the positioning block 16 is threaded with a fixing bolt 17 and the fixing bolt 17 is tightly pressed against the lower surface of the sliding frame 2. The distance between the special-shaped adjustment plate 14 and the side of the sliding frame 2 can be adjusted according to the end face thickness of the bearing ring, so as to facilitate the adjustment of bearing rings of different sizes to a vertical state and guide the bearing ring to roll to the rear support platform 3.

[0024] A supporting platform 3 for receiving the bearing ring is provided on the side of the sliding frame 2 away from the placing platform 1, and a first grinding mechanism and an adjustable second grinding mechanism are respectively provided on both sides of the upper surface of the supporting platform 3.

[0025] The second grinding mechanism includes a second bracket 21, a second grinding belt 22, a third motor 23 and a first electric push rod 24. The second bracket 21 is slidably connected to the side of the upper surface of the support platform 3 away from the first bracket 18. The second grinding belt 22 is rotatably connected to the inside of the second bracket 21 and is arranged on the upper surface of the support platform 3. The third motor 23 is fixedly connected to the side of the lower surface of the support platform 3 close to the second bracket 21, and the driving shaft passes through the upper surface of the support platform 3 and is connected to the rotating shaft of the second grinding belt 22. The third motor 23 drives the rotating shaft in the second grinding belt 22 to rotate counterclockwise, which can drive the second grinding belt 22 to rotate counterclockwise, and cooperate with the first grinding belt 19 rotating clockwise, so as to push the bearing ring passing through the two forward, and at the same time, the end faces on both sides of the bearing ring can be polished. Friction, the fixed rod part of the first electric push rod 24 is fixedly connected to the side of the supporting platform 3 and the movable rod part passes through the side of the supporting platform 3 and is connected to the second bracket 21. The lateral position of the second grinding mechanism can be adjusted by the first electric push rod 24, so as to facilitate the adjustment of the distance between the second grinding mechanism and the first grinding mechanism. The distance between the second grinding mechanism and the first grinding mechanism on the side close to each other can be adjusted according to the end face thickness of the bearing to be consistent with the end face thickness of the bearing ring, so that the bearing ring rolls between the first grinding mechanism and the second grinding mechanism, and the first grinding belt 19 and the second grinding belt 22 can grind the bearing ring, and the first grinding belt 19 rotates clockwise and the second grinding belt 22 rotates counterclockwise, which can drive the middle bearing ring to move forward, so as to facilitate the transportation of the bearing ring.

[0026] A fixing frame 4 is fixedly installed on the side of the supporting platform 3, and a lateral adjustment mechanism is arranged on the top of the fixing frame 4, the lateral adjustment mechanism comprises a second electric push rod 25 and a lateral movable plate 26, the fixed rod body part of the second electric push rod 25 is fixedly installed on the top of the fixing frame 4, and the movable rod body part passes through one side of the top of the fixing frame 4 and is fixedly connected with the lateral movable plate 26, the number of the fixing frame 4 and the second electric push rod 25 are both two, and the two fixing frames 4 are symmetrically arranged with the vertical center line of the supporting platform 3 as the symmetry axis, the two second electric push rods 25 are respectively fixedly installed on the top of the two fixing frames 4, and the movable rod body parts of the two second electric push rods 25 are respectively connected to the two sides of the lateral movable plate 26, when the position of the second grinding mechanism is adjusted according to the end face thickness of the bearing ring, the lateral movable plate 26 can be driven to move laterally by the second electric push rod 25, so that the pressing mechanism on the lateral adjustment mechanism can always correspond to the middle part of the bearing ring, so that the pressing mechanism can correspond to the bearing ring and fully contact with it.

[0027] The movable end of the lateral adjustment mechanism is provided with a pressing mechanism that can press the top of the bearing ring tightly. The pressing mechanism includes a third electric push rod 27, a sleeve rod frame 28, a pressing rod 29, a spring 30 and a pulley 31. The fixed rod body part of the third electric push rod 27 is fixedly installed on the upper surface of the transverse movable plate 26 and the movable rod body part is penetrated through the lower surface of the transverse movable plate 26. The sleeve rod frame 28 is fixedly connected to the movable rod body of the third electric push rod 27. The third electric push rod 27 can drive the sleeve rod frame 28 and the pulley 31 below to move up and down, so as to facilitate the adjustment of the height of the pulley 31 according to the diameter of the bearing ring, so that the pulley 31 can be easily pressed against the top of the bearing ring with different diameters.

[0028] The top of the pressing rod 29 is fixedly connected with a spring 30, and the top of the spring 30 is fixedly connected to the inner top wall of the sleeve rod frame 28. The spring 30 can provide a downward elastic force to the pressing rod 29, which can make the pulley 31 press against the top of the bearing ring, so that the bearing ring can only move forward in a straight line on the supporting platform 3 under the friction force of the first grinding belt 19 and the second grinding belt 22, and will not move upward. The top of the pressing rod 29 is penetrated at the bottom of the sleeve rod frame 28 and the pulley 31 is installed at the bottom of the pressing rod 29. The number of the pressing rods 29 and the pulley 31 is several, and several pressing rods 29 are evenly and equidistantly penetrated at the bottom of the sleeve rod frame 28. The pressing mechanism is arranged at the top of the middle part of the first grinding mechanism and the second grinding mechanism. The multiple pressing rods 29 and the pulley 31 are independent of each other and the activities between them are not affected. When the friction drives the bearing ring to move forward, the top of the bearing ring will push the pulley 31 and the downward pressure rod 29 above it in turn. Multiple groups of pulleys 31 abutting against the top of the bearing ring can exert downward pressure on the bearing, thereby ensuring that the bearing ring will not move upward and can only move horizontally. The horizontal forces exerted on the bearing ring by the pulleys 31 abutting against the arc surfaces on the front and rear sides of the top of the bearing ring will offset each other. The bearing ring will be subjected to the downward force of the multiple pulleys 31 abutting against it and the horizontal friction force exerted on it by the first grinding belt 19 and the second grinding belt 22. The bottom of the bearing ring abuts against the fixed support platform 3. Therefore, the bearing ring will not move vertically and can only move horizontally driven by the friction force exerted by the first grinding belt 19 and the second grinding belt 22. Therefore, the end faces on both sides of the bearing ring can be polished while being conveyed forward, thereby greatly improving the polishing efficiency.
