Description

Technical Field

[0001] The invention relates to the technical field of bearing assembly, in particular to a bearing assembly device for motor production. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (also known as a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electrical rotational torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized conductor in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of the motor is the effect of the magnetic field on the force of the current, causing the motor to rotate. Among them, bearings are an important component in contemporary mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] At present, after the bearing is manufactured separately, it needs to be assembled on the rotor and finally assembled to the motor with the rotor. In the prior art, in order to install the bearing on the rotor through matching, it is necessary to first fix the rotor, then put the bearing on the end of the rotor, and finally push or knock the end face of the bearing. The usual method is to use manual knocking or machine pushing. However, manual knocking can easily cause uneven force application, resulting in the bearing being slightly tilted on the rotor after assembly and unable to fully fit. At the same time, the pushing method of the existing machine is to apply pressure to the bearing and push it directly, which can easily cause damage to the bearing. For this reason, we propose a bearing assembly device for motor production. Summary of the invention

A mounting groove adapted to the metal block 2 is opened on the base 1, which is conducive to replacing different metal blocks 2 and adapting to rotors 47 of different sizes. In order to facilitate the matching between the placement plate 10 and the protective plate 14, the shaft After the bearing 48 is installed between the placement plate 10 and the protective plate 14, the pressing rod 18 presses the placement plate 10, the bearing 48 and the protective plate 14 downward to prevent damage to the bearing 48. The first groove 12 and the second groove 15 are adapted in size, and the opening directions of the first groove 12 and the second groove 15 are the same. At the same time, due to the arrangement of the first groove 12 and the second groove 15, the placement plate 10 and the protective plate 14 are never in contact with the rotor 47, but the protective plate 14 is in contact with the output end of the pressing rod 18 above.

[0032] By controlling the assembly component 7 to operate first, the rotating shaft 9 is driven to rotate, and then the placement plate 10 located in the storage slot 4 is rotated with the rotating shaft 9 as the center, until the placement plate 10 is rotated to be perpendicular to the support seat 3 when viewed from the side, and the bearing 48 is manually sleeved on the top of the rotor 47 and located on the placement plate 10.

[0033] The assembly component 7 includes two groups of first gears 20 respectively fixed at both ends of the rotating shaft 9 and located outside the support seat 3, the first gear 20 is meshedly connected with a rack 21 slidably connected to the support seat 3, a bending frame 22 slidably connected to the support seat 3 is fixedly connected between the bottom ends of the two groups of racks 21, and a plurality of groups of blocking blocks 23 fixedly connected to the support seat 3 are arranged above the bending frame 22. When the placement plate 10 and the support seat 3 are in a vertical state, the bottom end of the blocking block 23 is in contact with the bending frame 22, and a power mechanism 24 connected to the bending frame 22 is arranged on the rear side of the support seat 3. The power mechanism 24 includes a first electric telescopic rod 25 arranged on the rear side of the support seat 3 and fixedly connected thereto, a first power shaft 26 is arranged in the first electric telescopic rod 25, and a connecting block 27 fixedly connected to the bending frame 22 is arranged on the rear side of the support seat 3. The connecting block 27 is sleeved on the first power shaft 26, and a rubber ring 28 sleeved on the first power shaft 26 is arranged in the connecting block 27, and the rubber ring 28 is close to the outer side of the first power shaft 26;

[0034] The first power shaft 26 in the first electric telescopic rod 25 extends upward, and through the friction between the first power shaft 26 and the rubber ring 28, the first power shaft 26 drives the connecting block 27 upward when extending, and the connecting block 27 drives the fixedly connected bending frame 22 to slide upward on the support seat 3, and the two sets of racks 21 at the top of the bending frame 22 rise synchronously. Through the meshing connection between the rack 21 and the first gear 20, the rack 21 drives the first gear 20 to rotate when it rises, and the first gear 20 then drives the rotating shaft 9 to rotate. At this time, the placement plate 10 located in the storage slot 4 rotates with the rotating shaft 9 as the center of the circle until the placement plate 10 rotates to be perpendicular to the support seat 3 when viewed from the side. At the same time, the bending frame 22 rises to the bottom end of the blocking block 23 and fits with the bottom end of the blocking block 23.

[0035] The protection component 13 includes a limiting sleeve 29 which is arranged in the limiting groove 11 and is slidably connected to the placement plate 10. The limiting sleeve 29 is provided with a plurality of groups of first springs 30 which are fixedly connected to the limiting sleeve 29 at one end. The top of the first spring 30 is fixedly connected to a limiting block 31 which is slidably connected to the inside of the limiting sleeve 29. The tops of the plurality of groups of limiting blocks 31 are fixedly connected to vertical blocks 32 which are fixedly connected to the protection plate 14. A trigger mechanism 33 connected to the lifting frame 8 is arranged on the side of the limiting sleeve 29 close to the support seat 3. The trigger mechanism 33 includes a mounting block 34 which is arranged on the lifting frame 8 and is fixedly connected to the lifting frame 8. A second electric telescopic rod 35 which is slidably connected to the support seat 3 is fixedly connected to the mounting block 34. The output end of the second electric telescopic rod 35 faces the limiting sleeve 29, and the output end of the second electric telescopic rod 35 is fixedly connected to a pushing plate 36. A trigger switch 37 is arranged on the outer surface of the second electric telescopic rod 35. The trigger end of the trigger switch 37 faces upward, and the trigger switch 37 is electrically connected to the second electric telescopic rod 35.

[0036] The placement plate 10 presses the trigger switch 37 on the second electric telescopic rod 35 below. Since the trigger switch 37 is electrically connected to the second electric telescopic rod 35, after the trigger switch 37 is pressed, the second electric telescopic rod 35 is controlled to operate, and its output end extends toward the limit sleeve 29. The push plate 36 at the output end pushes the limit sleeve 29 to make the limit sleeve 29 slide in the limit groove 11 toward the bearing 48. The limit sleeve 29 drives the protective plate 14 to move above the bearing 48 through the vertical block 32. At this time, the top view of the first groove 12 and the second groove 15 are in an overlapping state.

[0037] The pressing assembly 16 includes an extended shaft 38 which is arranged on the first power shaft 26 and fixedly connected to the first power shaft 26 at one end, a frame frame 39 which is slidably connected to the top of the extended shaft 38 is fixedly connected to the top of the frame frame 39, a connecting shaft 40 is fixedly connected to the top of the frame frame 39, a connecting ring 41 is rotatably connected to the connecting shaft 40, a hard tube 42 which is located on the top of the hydraulic push rod 17 is arranged on the top of the top of the top seat 6, a switch valve 43 which is connected to the connecting ring 41 is arranged on the hard tube 42, a rebound mechanism 44 which is located below the lifting frame 8 is arranged in the storage groove 4, the rebound mechanism 44 includes a plug-in shaft 45 which is arranged at the bottom of the lifting frame 8 and fixedly connected to the top of the lifting frame 8, the bottom end of the plug-in shaft 45 is located in the support seat 3, and the plug-in shaft 45 is slidably connected to the support seat 3, and a second spring 46 which is sleeved on the plug-in shaft 45 is arranged between the lifting frame 8 and the support seat 3;

[0038] The extension shaft 38 above the first power shaft 26 is pushed up, and the extension shaft 38 pushes up the frame frame 39 at the top, and the connecting shaft 40 at the top of the frame frame 39 rises synchronously, and the switch valve 43 is driven upward through the connecting ring 41 to open the switch valve 43, so that the hard pipe 42 is connected with the hydraulic push rod 17, and the hydraulic push rod 17 is further operated to extend the pressing rod 18 downward. At this time, the rotor 47 gradually moves into the cavity 19 on the pressing rod 18 until the pressing rod 18 is pressed. The bottom end of the pressure rod 18 contacts the top surface of the protective plate 14 and pushes the protective plate 14 to move downward until the bottom surface of the protective plate 14 contacts the top of the bearing 48, and drives the bearing 48 and the placement plate 10 to continue to move downward. When the placement plate 10 moves downward, the rotating shaft 9 moves downward in the sliding groove 5, and the plug-in shaft 45 slides into the support seat 3, the second spring 46 is squeezed, and finally, under the push and pressure of the pressing rod 18, the bearing 48 is installed on the rotor 47.

[0039] When the bearing 48 is assembled on the rotor 47, the metal block 2 is first replaced according to the specifications of the rotor 47 of the batch, and then the rotor 47 to be assembled with the bearing 48 is installed on the metal block 2. Then, the first electric telescopic rod 25 at the rear side of the support seat 3 is controlled to operate, and the first power shaft 26 in the first electric telescopic rod 25 is extended upward. Through the friction between the first power shaft 26 and the rubber ring 28, the first power shaft 26 drives the connecting block 27 upward when extending, and the connecting block 27 drives the fixedly connected bending frame 22 to slide upward on the support seat 3, and the two sets of racks 21 at the top of the bending frame 22 are synchronously moved upward. The rack 21 is meshed with the first gear 20, and the rack 21 drives the first gear 20 to rotate when it rises, and the first gear 20 then drives the rotating shaft 9 to rotate. At this time, the placement plate 10 located in the storage slot 4 rotates with the rotating shaft 9 as the center, until the placement plate 10 rotates to be vertical to the support seat 3 when viewed from the side. At the same time, the bending frame 22 rises to the bottom end of the blocking block 23 and fits with the bottom end of the blocking block 23, so that the placement plate 10 maintains the current position and state. At this time, the rotor 47 is located in the first groove 12, and then the bearing 48 is manually sleeved on the top of the rotor 47 and located on the placement plate 10;

[0040] After the side view angle of the placement plate 10 is perpendicular to the support seat 3, the placement plate 10 presses the trigger switch 37 on the second electric telescopic rod 35 below. Since the trigger switch 37 is electrically connected to the second electric telescopic rod 35, after the trigger switch 37 is pressed, the second electric telescopic rod 35 is controlled to operate, and its output end extends toward the limit sleeve 29, and the push plate 36 at the output end pushes the limit sleeve 29 to make the limit sleeve 29 slide in the limit groove 11 toward the bearing 48. The limit sleeve 29 drives the protective plate 14 to move above the bearing 48 through the vertical block 32. At this time, the top view angles of the first groove 12 and the second groove 15 are in an overlapping state, and the placement plate 10 and the protective plate 14 are never in contact with the rotor 47;

[0041] The first electric telescopic rod 25 continues to operate, and the bending frame 22 is restricted. When the first power shaft 26 continues to move upward, it rubs against the rubber ring 28, and the extension shaft 38 above the first power shaft 26 is pushed upward, and the extension shaft 38 then pushes the top frame 39 upward, and the connecting shaft 40 at the top of the frame 39 rises synchronously, and drives the switch valve 43 upward through the connecting ring 41 to open the switch valve 43, so that the hard tube 42 is connected with the hydraulic push rod 17, and the hydraulic push rod 17 is further operated to extend the pressing rod 18 downward. At this time, the rotor 47 gradually moves into the cavity 19 on the pressing rod 18 until the bottom end of the pressing rod 18 contacts the top surface of the protective plate 14 and pushes the protective plate 14 downward. Move, at this time, the vertical plate drives the limit block 31 to gradually slide into the limit sleeve 29, and the first spring 30 is squeezed until the bottom surface of the protective plate 14 contacts the top of the bearing 48, and drives the bearing 48 and the placement plate 10 to continue to move downward. When the placement plate 10 moves downward, the rotating shaft 9 moves downward in the sliding groove 5, and the plug-in shaft 45 slides into the support seat 3, and the second spring 46 is squeezed. Finally, under the push and pressure of the pressing rod 18, the bearing 48 is installed on the rotor 47. During this process, the placement plate 10 and the protective plate 14 are always not in contact with the rotor 47, but the setting of the placement plate 10 and the protective plate 14 achieves the effect of preventing damage to the bearing 48 while stably installing the bearing 48.
