Description

Technical Field

[0001] The present invention relates to the technical field of end - cap pressing, and particularly to an automatic pressing device for a motor end - cap. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy, thereby driving a device to work. To ensure the overall performance and service life of the motor, end - caps are usually added to both sides of the motor to prevent dust and objects from entering the interior of the motor. To ensure the normal output of the motor output end, when processing the motor end - cap, a bearing needs to be pressed into the end - cap. After the bearing is pressed into the motor end - cap, the tight combination between the bearing and the end - cap can withstand the axial force generated during the operation of the motor, preventing the bearing from being damaged due to uneven force.

[0003] Currently, the patent with the publication number CN116488417A discloses an automatic processing device for pressing a bearing into a motor end - cap, including a box body, and also including a clamping device, a flattening device, a lubricating device, and a protection device; the clamping device includes a transfer table, a guide plate, a fixing plate, a transmission rod, a clamping plate, a limiting disc, and a roller. The transfer table is installed on the inner wall of the box body, the guide plate is fixedly connected to the inner wall of the box body, the fixing plate is fixedly connected to the surface of the transfer table, the transmission rod is slidably connected to the inner wall of the fixing plate, the clamping plate is fixedly connected to the end of the transmission rod away from the guide plate, the limiting disc is fixedly connected to the end of the transmission rod away from the clamping plate, and the roller is rotatably connected to the inner wall of the limiting disc on the side away from the transmission rod; the flattening device includes a left support plate, a pressing roller, a right support plate, a cylinder, a pressing plate, a connecting plate, and a convex plate. The left support plate is fixedly connected to the inner wall of the box body, the pressing roller is rotatably connected to the inner wall of the left support plate, the right support plate is fixedly connected to the inner wall of the box body, the cylinder is fixedly connected to the top of the right support plate, and the pressing plate is fixedly connected to the output end of the cylinder. Through the coordinated operation of the first elastic plate, the oil - absorbing cotton, the baffle, the arc - shaped plate, and the inclined block, the oil - absorbing cotton brushes the oil liquid on the surface of the bearing, so that when the subsequent bearing is pressed, the oil liquid can play a lubricating role, enabling the bearing to be pressed into the motor more smoothly. Through the coordinated operation of the slideway, the elastic piece, the rotating plate, the dial rod, and the convex block, the elastic piece can buffer the motor to prevent the motor from being knocked, and at the same time, the intermittent opening of the rotating plate can realize the intermittent discharging of the motor, preventing the motors from colliding with each other when discharging together and causing damage to the motors.

[0004] However, the following problems still exist during the use of the current motor end - cap pressing device:

[0005] When the above-mentioned device is in use, it is necessary to manually place the motor end cover and the bearing on the conveying device, and then press them together. During this process, since the end cover is fixed by clamping, the end cover is likely to slide downward due to pressing, and it needs to be manually placed, which is very inconvenient, increasing the participation of workers and requiring manual alignment when placing, thus increasing the processing steps. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides an automatic pressing device for a motor end cover, which can realize automatic feeding of the end cover during rotational conveying through a linkage method, eliminating the need for manual participation, and automatically pushing and discharging materials through the linkage, which is more convenient and fast.

[0007] The present invention provides the following technical solutions: an automatic pressing device for a motor end cover, including a workbench, with fixed top plates fixedly arranged at its four corner positions, and a protective plate is arranged on the upper surface of the workbench, and a rotating plate is arranged at the upper end of the protective plate, and a limiting component is arranged on the rotating plate; a pushing plate is slidably arranged in a cylindrical groove opened on the rotating plate, and a moving plate is fixedly arranged at the lower end of the pushing plate, a motor is arranged at the lower end of the workbench, and the output end of the motor is provided with a first pulley group and a second pulley group through a rotating shaft, the first pulley group is coaxially provided with a driving wheel, and a driven wheel is meshed on the side of the driving wheel, and the driven wheel is fixedly connected with the rotating plate through a rotating shaft, a bevel gear group is arranged on the rotating shaft of the output end of the motor, and a pushing wheel is coaxially arranged with the bevel gear group, the second pulley group is coaxially provided with a third pulley group, and the third pulley group is coaxially provided with a semi-gear tooth, and the semi-gear tooth is meshed with a moving gear, the moving gear is meshed on the side with a fixed rack, and a blanking plate is arranged at the lower end of the fixed rack.

[0008] Further, the limiting component includes a fixed ring and a support plate, and a total of four fixed rings are provided, and the four fixed rings are arranged at equal angles on the upper surface of the rotating plate, and the support plate is fixedly installed in the fixed ring.

[0009] Further, a connecting spring is arranged on the upper surface of the moving plate, and the connecting spring is fixedly installed at the lower end of the rotating plate, and the moving plate is elastically connected with the rotating plate through the connecting spring, and the lower end of the moving plate is in mutual contact with the pushing wheel. Through the above structure, it is convenient to push the moving plate back to its original position under the action of the connecting spring.

[0010] Further, four groups of tooth structures are equiangularly arranged on the driving wheel, and gaps are provided between each group of tooth structures arranged on the driving wheel. Moreover, both the driving wheel and the driven wheel form a rotating mechanism with the protection plate through the bearings installed on the protection plate. With the above structure, it is convenient to drive the driven wheel to rotate intermittently through the driving wheel, and while supporting the driving wheel, it does not affect the rotation of the driving wheel to push the moving plate.

[0011] Further, the pushing wheel is composed of two semi-circles with different diameters, and the outer surface of the pushing wheel is set to be smooth. Moreover, the pushing wheel is rotationally connected to the fixed top plate through a rotating shaft. With the above structure, it is convenient to drive the moving plate to move up and down through the rotation of the pushing wheel.

[0012] Further, two moving gears are provided in total, and they are symmetrically distributed about the center of the semi-tooth. At the same time, the semi-tooth has the same diameter as the moving gear. With the above structure, it is convenient to drive the semi-tooth to move through the rotation of the moving gear.

[0013] Further, a limiting component is provided on the blanking plate, and the limiting component includes a limiting rod and a limiting spring. The limiting rod penetrates through the blanking plate and the fixed top plate, and the limiting spring is fixedly connected to the limiting rod. Moreover, the limiting spring is fixedly installed on the square plate-shaped structure at the upper end of the fixed top plate. With the above structure, it is convenient to realize the fitting and limiting of the end cover through the limiting rod, and avoid the situation that the end cover at the rear moves forward.

[0014] Further, a pushing plate is provided at the lower end of the blanking plate, and the pushing plate is slidably connected to the fixed top plate through a through long strip groove opened on the fixed top plate.

Moreover, a material sliding plate is fixedly installed on the driving rotating shaft. With the above structure, it is convenient for the blanking end cover to slide down from the material sliding plate with shock absorption, and avoid the situation that the end cover directly falls into the collection box from a relatively high height and causes collision deformation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The automatic pressing device for the motor end cover can drive the blanking plate to move when driving the rotating plate to rotate through a linkage method. As the blanking plate moves, it can drive the feeding of the motor end cover placed on the upper end of the fixed top plate, achieving the purpose of automatic feeding. During feeding, the limiting rod can be used to separate multiple end covers to prevent the end covers at the back from sliding forward. And as the motor end cover is pushed up, through the movement of the pushing plate, the purpose of automatically discharging the already pressed end cover can be achieved. During the discharging process, through the rotation of the material sliding plate, the purposes of guiding the material and damping can be achieved, avoiding the situation where the end cover collides due to directly falling from a high place. Thus, the automatic feeding and discharging of the end cover can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Please refer to Figures 1 - 11 , the present invention provides a technical solution: an automatic pressing device for a motor end cover, including a workbench 1, fixed top plates 2 are fixedly arranged at the four corners thereof, and a protective plate 3 is arranged on the upper surface of the workbench 1, and a rotating plate 4 is arranged at the upper end of the protective plate 3, and a limiting component 5 is arranged on the rotating plate 4; a push plate 6 is slidably arranged in a cylindrical groove opened on the rotating plate 4, and a moving plate 7 is fixedly arranged at the lower end of the push plate 6, a motor 9 is arranged at the lower end of the workbench 1, and a first pulley group 10 and a second pulley group 15 are arranged on the output end of the motor 9 through a rotating shaft, the first pulley group 10 is coaxially provided with a driving wheel 11, and a driven wheel 12 is meshed on the side surface of the driving wheel 11, and the driven wheel 12 is fixedly connected with the rotating plate 4 through a rotating shaft, a bevel gear set 13 is arranged on the rotating shaft of the output end of the motor 9, and a push wheel 14 is coaxially arranged with the bevel gear set 13; the limiting component 5 includes a fixed ring 501 and a support plate 502, four fixed rings 501 are provided in total, the four fixed rings 501 are arranged at equal angles on the upper surface of the rotating plate 4, and the support plate 502 is fixedly installed in the fixed ring (501); a connecting spring 8 is arranged on the upper surface of the moving plate 7, and the connecting spring 8 is fixedly installed at the lower end of the rotating plate 4, and the moving plate 7 is elastically connected with the rotating plate 4 through the connecting spring 8, and the lower end of the moving plate 7 is in mutual contact with the push wheel 14; four groups of tooth structures are arranged at equal angles on the driving wheel 11, and a gap is arranged between each group of tooth structures arranged on the driving wheel 11, and both the driving wheel 11 and the driven wheel 12 form a rotating mechanism with the protective plate 3 through bearings installed on the protective plate 3; the push wheel 14 is composed of two semi-circles with different diameters, and the outer surface of the push wheel 14 is set to be smooth, and the push wheel 14 is rotationally connected with the fixed top plate 2 through a rotating shaft.

[0032] When it is necessary to cut the already laminated motor end cover (a glue dispensing device and a laminating device are provided at the lower end of the fixed top plate 2, and both the glue dispensing device and the laminating device are of the existing structure of the laminating device, and their structures and working principles are the same as those of the existing ones, and a bearing feeding structure identical to the existing laminating device is provided directly behind the fixed top plate 2 to place the bearing into the end cover), the motor 9 starts to work. Since the output end of the motor 9 is connected to the first pulley group 10 through a rotating shaft, and the first pulley group 10 is coaxially connected to the driving wheel 11, and since the driving wheel 11 meshes with the driven wheel 12, at this time, as the driving wheel 11 rotates, the driven wheel 12 also starts to rotate. Since there are four groups of tooth structures arranged at equal angles on the driving wheel 11, and there are gaps between the four groups of tooth structures, and the total number of tooth structures provided on the driving wheel 11 is equal to the total number of tooth structures provided on the driven wheel 12 (the number of teeth in the attached figure is for illustration, and the specific number of teeth can be increased or decreased according to needs), that is, the driving wheel 11 drives the driven wheel 12 to rotate intermittently, and when the driving wheel 11 rotates one circle, the driven wheel 12 also rotates one circle. Since the driven wheel 12 is connected to the rotating plate 4, at this time, the rotating plate 4 starts to rotate intermittently. When the end cover to be cut rotates to the lower end of the guide cylinder 22, at this time, the driving wheel 11 no longer meshes with the driven wheel 12, and at this time, the rotating plate 4 stops rotating. Also, since the output end of the motor 9 meshes with the bevel gear set 13, and the bevel gear set 13 is composed of two bevel gears with different diameters (the diameter of the bevel gear connected to the output end of the motor 9 is twice the diameter of the bevel gear coaxially connected to the pushing wheel 14), and the bevel gear set 13 is coaxially connected to the pushing wheel 14, at this time, the pushing wheel 14 starts to rotate. Since the diameters of the two rotating wheels forming the first pulley group 10 are different, that is, the diameter of the rotating wheel connected to the motor 9 is half of the diameter of the rotating wheel coaxially connected to the driving wheel 11. Therefore, through the above rotation and the different diameters of the bevel gears, when the rotating plate 4 rotates one circle, the pushing wheel 14 needs to rotate four circles, so as to realize the pushing and feeding of the end covers at four positions. Through the rotation of the pushing wheel 14, the pushing wheel 14 starts to closely fit with the moving plate 7 and pushes the moving plate 7, that is, the moving plate 7 starts to move upward. Since a connecting spring 8 is installed on the moving plate 7, at this time, the connecting spring 8 starts to be squeezed and deformed. Since a pushing plate 6 is installed at the upper end of the moving plate 7, at this time, the pushing plate 6 also starts to move upward, so as to push the motor end cover located at the lower end of the guide cylinder 22. At this time, the already laminated motor end cover no longer fits with the support plate 502, that is, the motor end cover moves to the upper end position of the fixed ring 501, realizing the automatic ejection of the motor end cover.

[0033] A third pulley set 16 is coaxially arranged with the second pulley set 15, and a semi-gear 17 is coaxially arranged with the third pulley set 16. Moreover, a moving gear 18 is meshed with the semi-gear 17, a fixed rack 19 is meshed with the side of the moving gear 18, and a blanking plate 20 is arranged at the lower end of the fixed rack 19. There are two moving gears 18 in total, which are symmetrically distributed about the center of the semi-gear 17. At the same time, the semi-gear 17 and the moving gear 18 have the same diameter. A pushing plate 23 is arranged at the lower end of the blanking plate 20, and the pushing plate 23 is slidably connected with the fixed top plate 2 through a through long strip groove opened on the fixed top plate 2. A material guiding cylinder 22 is arranged at the lower end of the fixed top plate 2.

[0034] As the motor end cover that has been pressed is ejected, since the output end of the motor 9 is connected to the second pulley set 15, at this time, the second pulley set 15 starts to drive the third pulley set 16 coaxially connected thereto to rotate (the third pulley set 16 is composed of two runners and a belt, and the rotation diameter coaxially connected with the second pulley set 15 is twice that of the runner coaxially connected with the semi-gear 17), which can effectively ensure that the rotational speeds of the semi-gear 17 and the pushing wheel 14 are equal. At this time, the semi-gear 17 starts to rotate. Since the semi-gear 17 is set as a half-gear structure, at this time, the semi-gear 17 starts to rotate, that is, the semi-gear 17 starts to mesh with one side of the moving gear 18 (there are two moving gears 18 symmetrically arranged about the center of the semi-gear 17). At this time, one side of the moving gear 18 starts to be driven by the semi-gear 17 to rotate. Since the moving gear 18 meshes with the fixed rack 19, the fixed rack 19 starts to drive the blanking plate 20 to move away from the fixed top plate 2. Since the pushing plate 23 is installed at the lower end of the blanking plate 20, at this time, the pushing plate 23 also starts to move forward, that is, the pushing plate 23 starts to push out the ejected and already pressed motor end cover. The pushing plate 23 starts to fit with the lower end of the material guiding cylinder 22. At the same time, the blanking plate 20 starts to drive the motor end cover to move (the motor end cover is conveyed to the upper end of the fixed top plate 2 through a belt. At this time, with the movement of the blanking plate 20, the end cover near the arc part of the blanking plate 20 starts to be moved forward by the end cover in the rear position, and the end cover in the rear position will push the end cover in the front position as the belt conveys). At this time, the end cover pushed to the front position drops downward through the material guiding cylinder 22. At this time, the end cover drops onto the upper end of the pushing plate 23. Then, with the continuous rotation of the semi-gear 17, at this time, the semi-gear 17 starts to mesh with the other moving gear 18. At this time, the blanking plate 20 starts to move backward, and at this time, the pushing plate 23 also starts to move backward. At this time, the motor end cover on the upper end of the pushing plate 23 falls into the fixed ring 501, realizing automatic feeding and blanking of the motor end cover.

[0035] A limiting component 21 is provided on the blanking plate 20, and the limiting component 21 includes a limiting rod 211 and a limiting spring 212. The limiting rod 211 is disposed through the blanking plate 20 and the fixed top plate 2, and the limiting spring 212 is fixedly connected to the limiting rod 211. Moreover, the limiting spring 212 is fixedly installed on the square plate-like structure at the upper end of the fixed top plate 2; a rotating component 24 is provided on the fixed top plate 2, and the rotating component 24 includes a mounting plate 241, a driving rotating shaft 242, and a scroll spring 243. The mounting plate 241 is fixedly installed on the fixed top plate 2, the driving rotating shaft 242 is rotationally connected to the mounting plate 241 through a bearing installed on the mounting plate 241, the scroll spring 243 is fixedly installed in a groove formed on the mounting plate 241, and the scroll spring 243 is fixedly installed on the outer surface of the driving rotating shaft 242. Moreover, a material sliding plate 25 is fixedly installed on the driving rotating shaft 242.

[0036] As the blanking plate 20 moves backward, the blanking plate 20 begins to squeeze and push the limiting rod 211, that is, the limiting rod 211 begins to move away from the plate-like structure at the upper end of the fixed top plate 2 (two square plate-like structures are provided at the upper end of the fixed top plate 2, and the limiting rod 211 is disposed through both plate-like structures). As the limiting rod 211 moves, the limiting spring 212 installed on the limiting rod 211 begins to be stretched and deformed. At this time, the motor end cover at the rear begins to fit with the arc-shaped portion of the blanking plate 20, which is convenient for subsequent feeding of the motor end cover. When feeding the motor end cover, the blanking plate 20 begins to move forward. When the motor end cover that fits with the arc-shaped portion of the blanking plate 20 passes over the limiting rod 211, the extrusion on the limiting rod 211 is no longer applied at this time. That is, under the action of the restoring deformation of the limiting spring 212, the limiting spring 212 begins to pull the limiting rod 211 to move toward the blanking plate 20. At this time, the limiting rod 211 can be used to achieve fitting and limiting of the motor end cover at the rear, avoiding the situation that the rear end cover falls through the through groove formed at the front end of the fixed top plate 2 when the blanking plate 20 returns; when discharging the already press-fitted motor end cover, as the already press-fitted motor end cover is pushed, the already press-fitted motor end cover then falls onto the material sliding plate 25. At this time, the material sliding plate 25 begins to rotate. Because the material sliding plate 25 is connected to the driving rotating shaft 242, and a scroll spring 243 is installed outside the driving rotating shaft 242, the scroll spring 243 begins to be squeezed and deformed at this time. As the material sliding plate 25 rotates, the already processed motor end cover can be guided into the collection box, avoiding the situation of collision due to excessive dropping height.
