[0084] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0085] Reference Figures 1-5The electromagnetic attraction and extraction propulsion device 100 comprises a fixed plate 101, a support 102, a driving group 103, a sliding rod 104, an electromagnet 105 and a collection bag 106. A plurality of fixed spaced screw holes are arranged around the end surface of the bearing, and an opening for attracting the ball is arranged on the inner wall of the bearing. The opening is normally closed, and is opened when the ball is extracted. The fixed plate 101 is fixed on the end surface of the bearing through bolts and screw holes. The support 102 is arranged on the fixed plate 101. The driving group 103 is arranged on the support 102 and is used for driving the sliding rod 104 to slide. The support 102 is provided with a sliding groove 102a, and the sliding rod 104 is slidingly arranged in the sliding groove 102a. The electromagnet 105 is arranged at one end of the sliding rod 104. The support 102 is provided with a ball discharging outlet 102b, which is communicated with the sliding groove 102a. The collection bag 106 is arranged at the ball discharging outlet 102b and is used for collecting the ball.

[0086] When the bearing ball is extracted, the operator installs the fixed plate 101 on the upper end surface of the bearing, aligns the electromagnet 105 with the opening on the inner side of the bearing, and then opens the electromagnet 105 to attract the ball. After the ball is attracted, the driving group 103 is started to drive the sliding rod 104 to slide. When the attracted ball moves to the discharging outlet 102b, the electromagnet 105 is powered off, the ball rolls into the collection bag 106 under the action of gravity, and then the driving group 103 drives the sliding rod 104 to reset, and the electromagnet 105 is opened again to attract the ball in the bearing in sequence.

[0087] A plurality of screw holes with different specifications and positions are arranged on the fixed plate 101, so that bearings with different specifications can be adaptively installed. When the fixed plate 101 and the support 102 are fixed on bearings with different specifications, the electromagnetic attraction and extraction propulsion device 100 can be quickly removed or fixed on the bearing by disassembling and assembling the bolts on the fixed plate 101.

[0088] The driving group 103 comprises a first driving member 103a, a first gear 103b and a fixed sleeve 103c. The first driving member 103a is a servo motor and is fixed on the support 102. The first gear 103b is fixed on the output end of the first driving member 103a. The fixed sleeve 103c is slidingly arranged in the sliding groove 102a, and the sliding rod 104 is fixed in the fixed sleeve 103c. The sliding groove 102a is in the shape of a semicircle, and the fixed sleeve 103c is in the shape of a quadrant. A gear slot 103d is arranged on the side of the fixed sleeve 103c close to the first gear 103b, and the first gear 103b is engaged with the gear slot 103d.

[0089] When the sliding rod 104 is driven to slide, the first driving member 103a drives the first gear 103b to rotate, the first gear 103b drives the fixed sleeve 103c to rotate, and the fixed sleeve 103c drives the sliding rod 104 and the electromagnet 105 to reciprocate between the opening inside the bearing and the discharge port 102b.

[0090] An extension pipe 107 is fixed at the discharge port 102b of the support 102, and a collection bag 106 is located at the outlet end of the extension pipe 107. A counting component 108 is arranged on the extension pipe 107, and is used to count the number of balls discharged from the extension pipe 107.

[0091] The counting component 108 comprises a hinged plate 108a, a pressing rod 108b, an abutting plate 108c, a spring 108d, a connecting sleeve 108e, a pressure sensor 108f, and a display screen 108g. The hinged plate 108a is hinged to the inner wall of the extension pipe 107. The pressing rod 108b is arranged on the extension pipe 107 in a transverse sliding manner, and is located below the hinged plate 108a. The pressing rod 108b is a round rod. The abutting plate 108c is arranged on the pressing rod 108b, and is located close to one end of the hinged plate 108a. The abutting plate 108c is in abutment with the hinged plate 108a. The abutting plate 108c is disc-shaped, and the diameter of the abutting plate 108c is greater than the diameter of the pressing rod 108b. The spring 108d is sleeved on the pressing rod 108b, and two ends of the spring 108d are fixed to the abutting plate 108c and the inner wall of the extension pipe 107, respectively. The connecting sleeve 108e is fixed to the extension pipe 107, and is located on the sliding track of the pressing rod 108b. The pressing rod 108b slides into the connecting sleeve 108e. The pressure sensor 108f is fixed in the connecting sleeve 108e. The pressure sensor 108f can be a strain pressure sensor. Such a sensor is more easily integrated with a counter or a microcontroller in structure, so as to record the number of times of being pressed. The display screen 108g is fixed to the support 102, and is electrically connected with the pressure sensor 108f.

[0092] When the balls roll off the extension pipe 107, the hinged plate 108a is pressed to slide the pressing rod 108b in the direction of the pressure sensor 108f. Finally, the pressing rod 108b hits the pressure sensor 108f. When the balls roll into the collection bag 106, the spring 108d drives the pressing rod 108b and the hinged plate 108a to reset. When the next ball rolls, the pressure sensor 108f transmits data to the display screen 108g after being hit. The number of times of being hit is calculated, and the number of balls rolling off the extension pipe 107 is obtained.

[0093] The fixed plate 101 is fixed with a sliding plate 109, which is arranged vertically. The support 102 is provided with an embedding groove 102c matched with the sliding plate 109. The sliding plate 109 is embedded in the embedding groove 102c, so that the support 102 can slide on the fixed plate 101.

[0094] The pressing member 110 is screwed on the support 102, and one end of the pressing member 110 abuts against the sliding plate 109, for braking the support 102. By reversing the pressing member 110, the pressure between the pressing member 110 and the sliding plate 109 is changed, the friction between the sliding plate 109 and the support 102 is increased or decreased, and the support 102 is fixed or slid.

[0095] The support 102 is slidably connected with the fixed plate 101, so that the electromagnetic attraction and extraction propulsion device 100 can adjust the position of the electromagnet 105 according to the position of the opening for discharging the ball on the inner side wall of the bearing, and the electromagnet 105 can be aligned with bearings of different specifications, and the adaptability is improved.

[0096] The pouring assembly 111 is further arranged on the support 102, and the pouring assembly 111 comprises a pouring pipe 111a and an infrared sensor 111b. The pouring assembly 111 has an entrance on the support 102, which is communicated with the sliding groove 102a and located on the sliding track of the electromagnet 105. The pouring pipe 111a is fixed on the support 102 and located at the entrance and communicated with the sliding groove 102a. The infrared sensor 111b is arranged on the inner wall of the pouring pipe 111a and electrically connected with the display screen 108g.

[0097] The pouring pipe 111a is composed of a connecting portion 111c and a pouring portion 111d. The connecting portion 111c is fixed on the support 102 and communicated with the entrance. The infrared sensor 111b is arranged on the inner wall of the connecting portion 111c. The height of the end of the connecting portion 111c away from the entrance is lower than the height of the end of the connecting portion 111c close to the entrance, so that the ball is temporarily stored in the connecting portion 111c after being poured in. When the electromagnet 105 slides through the entrance, the ball is attracted into the sliding groove 102a by the electromagnet 105, and then the rear ball enters the connecting portion 111c. The pouring portion 111d is integrally formed on the connecting portion 111c and located at the end of the connecting portion 111c away from the entrance.

[0098] When the operator needs to put the repaired ball back into the bearing, the ball is put into the pouring part 111d, and then temporarily stored in the connecting part 111c. After the electromagnet 105 is powered on and passes through the entrance, the single ball temporarily stored in the connecting part 111c is attracted by the electromagnet 105, and the upper ball falls into the connecting part 111c. Then, the slide rod 104 drives the electromagnet 105 and the ball to roll in the opening direction of the bearing. When the ball moves into the bearing, the electromagnet 105 is powered off, and the ball falls into the bearing. The first driving part 103a drives the first gear 103b to rotate, and the first gear 103b drives the slide rod 104 to move upward and retract into the sliding groove 102a. The slide rod 104 again attracts the ball temporarily stored in the connecting part 111c. Then, the first driving part 103a drives the first gear 103b to reverse, and the first gear 103b drives the slide rod 104 to extend out of the sliding groove 102a, pushing the ball into the bearing, forming a cycle.

[0099] When the ball in the connecting part 111c is pushed into the bearing, the ball passes through the infrared sensor 111b, which detects the passing ball and records the number of passing balls, which is displayed on the display screen 108g.

[0100] The support 102 is provided with a revolution group 112, which includes a sliding plate 112a, a rotating shaft 112b, a second gear 112c, a third gear 112d, a second driving part 112e, a fourth gear 112f, and a screw rod 112g. The sliding plate 112a is horizontally slidably arranged on the support 102. The rotating shaft 112b is vertically rotatably arranged on the sliding plate 112a. The second gear 112c is fixed to the lower end of the rotating shaft 112b, and below the bearing is a lower ring 113 fixed with the outer ring of the bearing, and on the inner wall of the lower ring 113 is a meshing tooth 112h meshing with the second gear 112c. The third gear 112d is arranged on the upper end of the rotating shaft 112b. The second driving part 112e is arranged on the sliding plate 112a and located on one side of the rotating shaft 112b. The fourth gear 112f is arranged on the output end of the second driving part 112e, and the fourth gear 112f meshes with the third gear 112d. The screw rod 112g is threadedly connected to the support 102, one end of the screw rod 112g is rotatably connected to the sliding plate 112a, and the moving direction of the screw rod 112g is consistent with the sliding direction of the sliding plate 112a.

[0101] When the ball is sucked out of and pushed into the bearing, the second driving part 112e is started, and through the transmission of the fourth gear 112f, the third gear 112d, the rotating shaft 112b, the second gear 112c, and the meshing tooth 112h, the support 102 and the bearing are driven to rotate around the outer ring of the bearing, and the balls in the bearing are sequentially sucked out or pushed in.

[0102] As Figure 2As shown, the diameter of the third gear 112d is smaller than the diameter of the second gear 112c, the output torque of the second gear 112c is increased, the output torque of the second driving member 112e is reduced, and the second driving member 112e is protected by the engagement of the third gear 112d and the fourth gear 112f.

[0103] When the mounting bracket 102 is installed, the screw 112g is rotated to move the sliding plate 112a to the center of the bearing, so that the fourth gear 112f is disengaged from the inner ring of the bearing. Then the screw 112g is flipped to move the sliding plate 112a to the outer ring of the bearing, so that the fourth gear 112f is engaged with the meshing tooth 112h.

[0104] The volume of the electromagnetic attraction and extraction propulsion device 100 is controlled to be less than 50cm*50cm, which is small for large bearings and can be conveniently carried, saving time and effort. The device can be used to extract and install balls for large bearings of different specifications.
