A rapid assembly platform for a permanent magnet motor and its assembly process

Abstract

The invention discloses a permanent magnet motor rapid assembly platform and an assembly process thereof, and relates to the technical field of motor assembly. A shell clamping mechanism is used to clamp a motor shell after stator assembly. Due to the rotation of a rotating rod, the clamped motor shell can still be deflected, and then a support frame is pushed into the stator in the motor shell through a receiving column on a receiving mechanism. The stator is supported by the support frame so that the stator shaft core and the receiving column are coaxial, thereby determining the position of the stator shaft core, and then a friction plate is used to squeeze a friction disc, and the friction disc presses a limit rod so that the end of the limit rod contacts the side wall of a slide groove on a clamping seat, thereby limiting the relative swing between the clamping seat and the rotating rod. At the same time, the friction plate contacts the friction disc, limiting the rotation of the friction disc, thereby achieving locking of the deflection of the clamping seat, completing the positioning of the stator shaft core, so as to carry out stator-rotor docking assembly, without the need to adapt a clamping mold for the motor, and greatly reducing the production cost.

Description

Technical Field

[0001] The invention relates to the technical field of motor assembly, and in particular to a permanent magnet motor rapid assembly platform and an assembly process thereof. Background Art

[0002] The permanent magnet motor is composed of a stator, a rotor and a motor housing for installing the stator and the rotor. The stator is wound with coil windings, and the rotor is placed with high-quality permanent magnet poles. During the operation of the permanent magnet motor, the interaction between the stator windings and the magnetic field between the permanent magnets drives the rotor to rotate. During the assembly process of the permanent magnet motor, the stator is pre-fixed in the motor housing, and then the rotor is installed in the stator. In this process, in order to ensure the stability of the assembly and avoid the displacement of the motor housing during the assembly process, the clamping mechanism on the assembly platform needs to be used to clamp and position the motor housing to prevent the motor housing from moving.

[0003] The existing motor assembly device needs to use a specific mold when clamping the assembled motor, so that when clamping the motor shell, the axis core of the stator inside the motor shell can be determined, which facilitates the assembly operation of the stator and rotor. When the motor model changes, the clamping mold needs to be replaced and adapted, which will lead to a significant increase in production costs. Summary of the invention

[0018] A rapid assembly process for a permanent magnet motor is as follows:

[0019] S1. Assembly of the stator and the motor housing. Install the stator into the motor housing at the pre-installation base and fix it with adhesive.

[0020] S2. Place the assembled stator and motor housing between the positioning clamps. Push the two positioning clamps to close by the clamping rod to clamp the motor housing.

[0024] The beneficial effects of the present invention are:

[0025] The motor housing after assembling the stator is clamped by the housing clamping mechanism. Due to the rotation of the rotating rod, the clamped motor housing can still deflect. Then, the receiving column on the receiving mechanism pushes the support frame into the stator in the motor housing, and the support frame is used to expand the stator, so that the stator axis is coaxial with the receiving column, thereby determining the position of the stator axis. Then, the friction plate presses the friction disc, and the friction disc presses the limiting rod so that the end of the limiting rod contacts the side wall of the chute on the clamping seat, thereby restricting the relative swing between the clamping seat and the rotating rod. At the same time, the friction plate contacts the friction disc, restricting the rotation of the friction disc, thereby realizing the locking of the deflection of the clamping seat and completing the positioning of the stator axis for the butt joint assembly of the stator and the rotor. There is no need to adapt the clamping mold for the motor, which greatly reduces the production cost;

[0026] The telescopic push rod moves downward to push the rotor connecting sleeve, the rotor, and the rotor butt joint sleeve to move together. Due to the buffering of the support spring and the pressure-bearing spring, it can also reduce the buffering of the rotor connecting sleeve and the rotor butt joint sleeve to the stator.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0039] Embodiment 1:

[0040] like Figures 1 - 3 As shown, a permanent magnet motor rapid assembly platform comprises: a device bracket 1, a housing clamping mechanism 2, a rotor feeding mechanism 3, and a receiving mechanism 4;

[0041] A pre-installed base 11 is provided on the left side of the device bracket 1, and an assembly area 12 is provided on the right side. A transverse slide rail 21 is installed between the pre-installed base 11 and the assembly area 12, a moving seat 22 is installed on the moving part of the transverse slide rail 21, and a longitudinal slide rail 23 is installed on the moving seat 22;

[0042] The housing clamping mechanism 2 includes a clamping base 31, a clamping rod 32, a rotating rod 33, a limiting rod 34, a clamp seat 35, and a positioning clamp 36. The clamping base 31 is installed on the moving part of the longitudinal slide rail 23, and the clamping rod 32 is slidably installed on the clamping base 31. The clamping rod 32 is limited to move only along the axial direction by keyway cooperation. The clamping rod 32 moves along its own axial direction on the clamping base 31 under the push of the driving mechanism. The rotating rod 33 is rotatably installed on the clamping rod 32. The rotating rod 33 can only rotate on the clamping rod 32 and will not move axially relative to the clamping rod 32. The limiting rod 34 is slidably installed on the rotating rod 33. The contact surface between the limiting rod 34 and the rotating rod 33 is The keyway is connected to limit the relative rotation between the limit rod 34 and the rotating rod 33, so that the limit rod 34 can only move along the axial direction relative to the rotating rod 33. A slide groove 37 is provided on the clamp seat 35, and the end of the rotating rod 33 is located in the slide groove 37. One end of the limit rod 34 can be inserted into the slide groove 37 through the end of the rotating rod 33. A friction disk 38 is fixed to the other end of the limit rod 34. The positioning clamp 36 is installed on the clamp seat 35. Limiting plates 39 are respectively provided on both sides of the clamping base 31. A friction plate 40 is provided between the limiting plate 39 and the friction disk 38. A limiting spring 41 is installed on the limiting plate 39. The limiting spring 41 applies a thrust to the friction plate 40 in the direction of the friction disk 38.

[0043] The rotor feeding mechanism 3 and the receiving mechanism 4 are both arranged on the device support 1 of the assembly area 12, the rotor feeding mechanism 3 is located at the upper part of the transverse slide rail 21, and the receiving mechanism 4 is located at the lower part of the transverse slide rail 21;

[0044] The receiving mechanism 4 includes a lifting platform 42, a receiving column 43 is installed on the lifting platform 42, and a support frame 44 is installed on the receiving column 43;

[0045] When assembling the motor, the motor housing and the stator are installed on the pre-installation base 11. The clamping rod 32 drives the rotating rod 33, the limiting rod 34 and the clamp seat 35 to move together to clamp the motor housing. After the assembly of the motor housing and the stator is completed, the moving seat 22 is pushed to move, so that the moving seat 22 moves to the assembly area 12, and the friction plate 40 is separated from the friction disc 38. At this time, without the action of pressure, the friction disc 38 and the limiting rod 34 will not exert pressure on the side wall of the chute 37 on the clamp seat 35, and the clamp seat 35 can move relative to the rotating rod 33. At the same time, the rotating rod 33 can also rotate relative to the clamping rod 32. The positions of the motor housing and the stator are adjusted through the horizontal slide rail 21 and the vertical slide rail 23, so that the receiving column 43 on the lifting table 42 is inserted into the inner cavity of the stator from below, and the support frame 44 on the receiving column 43 contacts the side wall of the inner cavity of the stator. The support frame 44 is a tripod that can expand outward and is coaxial with the receiving column 43. As the support frame 44 contacts the side wall of the inner cavity of the stator, the stator and the motor housing as a whole deflect, so that the stator deflects to a position coaxial with the receiving column 43, correcting the angular deviation of the stator axis. At this time, the friction plate 40 is loosened, so that the friction plate 40 contacts the friction disc 38. The friction plate 40 presses the friction disc 38 under the action of the limiting spring 41. The pressure acts on the limiting rod 34, and the limiting rod 34 presses the side wall of the chute 37, restricting the movement of the chute 37 relative to the rotating rod 33, thereby locking the displacement of the clamp seat 35. At the same time, due to the action of pressure on the friction disc 38, the friction disc 38 cannot rotate, thereby restricting the rotation of the rotating rod 33. Since the rotating rod 33 and the clamping seat cannot move, the angular deviation of the axis of the clamped motor housing and stator as a whole can be maintained at this time, and the axis of the stator can be positioned, which is convenient for the docking of the stator and the rotor;

[0046] When the motor model changes, it is not necessary to reconfigure the assembly mold of the motor, and the stator axis can also be positioned, which greatly reduces the production cost.

[0047] Embodiment 2:

[0048] On the basis of Embodiment 1, as Figure 2 shown, two threaded sleeves 51 are symmetrically arranged on the clamping base 31. Each threaded sleeve 51 corresponds to a clamping rod 32 and is sleeved on the clamping rod 32 by means of threaded connection. The outside of the threaded sleeve 51 is connected to the clamping gear ring 52 by means of gear meshing. The clamping gear ring 52 is rotatably installed on the clamping base 31 and is driven to rotate by the clamping motor 53. The rotation of the clamping motor 53 drives the clamping gear ring 52 to rotate. The clamping gear ring 52 drives the threaded sleeve 51 to rotate. The threaded sleeve 51 pushes the clamping rod 32 to slide on the clamping base 31 through the thread matching with the clamping rod 32;

[0049] As Figure 2 、 Figure 6As shown, a positioning groove 54 is provided on the clamping base 31, a lower pressing groove 55 is provided on the friction plate 40, a clamping plate 56 is slidably installed in the lower pressing groove 55, a pressing spring 57 is provided between the clamping plate 56 and the upper end of the lower pressing groove 55, the clamping plate 56 can be inserted into the positioning groove 54, a lifting rod 58 is provided in the positioning groove 54, the clamping plate 56 is inserted into the positioning groove 54, and the clamping plate 56 can be pushed out of the positioning groove 54 by lifting the lifting plate 58;

[0050] When the motor housing needs to be clamped, the two clamping rods 32 move in similar directions, and when the clamped motor housing is released, the two clamping rods 32 move in opposite directions. As the two clamping rods 32 separate, the clamping rods 32 drive the limiting rods 34 and the friction disc 38 to move as a whole, and the friction disc 38 pushes the friction plate 40 to move. When the clamping plate 56 moves to the position of the lower pressing groove 55 on the clamping base 31, the clamping plate 56 is inserted into the lower pressing groove 55 under the action of the top pressure spring 57. The lower pressing groove 55 limits the position of the friction plate 40. After the friction disc 38 is separated from the friction plate 40, the state of the friction plate 40 can be maintained, and the stator shaft core positioning in the next motor assembly process is convenient when the receiving structure is docked with the next motor to be assembled.

[0051] like Figure 2 , Figure 7 As shown, a buffer mechanism 201 is provided between the side of the friction plate 40 close to the friction disc 38 and the clamping base 31, and the buffer mechanism 201 includes a buffer rod 211, a buffer cylinder 212, and a one-way valve 213; a buffer piston 214 is installed inside the buffer cylinder 212, one end of the buffer rod 211 is fixed on the buffer piston 214, and the other end is connected to the friction plate 40, and the one-way valve 213 is installed at the rear end of the buffer cylinder 212, and a damping hole 215 is provided at the rear end of the buffer cylinder 212; when the assembled motor is unloaded, the friction plate 40 is moved by the thrust of the friction disc 38, driving the buffer piston 214 in the buffer cylinder 212 Move, at this time, the external air flow enters the buffer cylinder 212 through the one-way valve 213, and the buffer piston 214 can move normally without being affected by the resistance of the air pressure inside the piston cylinder 212. After the shaft core is corrected, when the clamped motor housing needs to be positioned and locked, the friction plate 40 moves close to the friction disk 3. At this time, the one-way valve 213 is closed, and the gas in the buffer cylinder 212 can only be discharged to the outside through the damping hole 215. The slow air pressure change inside the buffer cylinder 212 can buffer the friction plate 40, preventing the friction plate 40 from hitting the friction disk 38 under pressure when the clamping plate 56 is separated from the lower pressure groove 55.

[0052] Embodiment 3:

[0053] On the basis of Example 1, Figure 3 , Figure 4As shown, the inner side of the sliding groove 37 is a spherical structure. A connecting seat 61 is fixed at the end of the rotating rod 33. The connecting seat 61 is located in the sliding groove 37. As the connecting seat 61 generates relative displacement with the spherical surface of the sliding groove 37 in the sliding groove 37, it will drive the clamp seat 35 to deflect. Two symmetrically arranged pressing blocks 62 are slidably installed on the connecting seat 61. A friction plate 63 is fixed on the side of the pressing block 62 close to the sliding groove 37. An inclined surface that can contact the limiting rod 34 is provided on the side of the pressing block 62 far from the sliding groove 37 side;

[0054] When the limiting rod 34 is under the pressure of the friction disc 38, the end of the limiting rod 34 presses the inclined surface of the pressing block 62, and then forms a thrust acting on the pressing block 62 towards the side wall of the sliding groove 37, so that the pressing block 62 pushes the friction plate 63 towards the side wall of the sliding groove 37, increasing the friction between the connecting seat 61 and the sliding groove 37. Due to the increase in friction force, the relative movement between the connecting seat 61 and the sliding groove 37 is restricted, and the rotating rod 33 is restricted to a fixed position in the sliding groove 37, completing the locking of the deflection of the clamp seat 35.

[0055] Embodiment 4:

[0056] On the basis of Embodiment 1, as Figure 1 、 Figure 8 、 Figure 9 shown, a support cylinder 71 is fixed on the lifting table 42. A limiting groove 72, an annular rotating groove 73 and a vertical guide groove 74 are provided on the inner side wall of the support cylinder 71. The limiting groove 72 and the guide groove 74 communicate with the rotating groove 73 respectively to form a communicating groove. The guide groove 74 and the limiting groove 72 are arranged alternately. The side walls of the rotating groove 73 opposite to the openings of the limiting groove 72 and the guide groove 74 are inclined cut surfaces 75. The connecting surface 76 between the guide groove 74 and the limiting groove 72 is perpendicular to the inclined cut surface 75. One end of the receiving column 43 is installed in the support cylinder 71. A convex column 77 is fixed on the outside of one end of the receiving column 43. The convex column 77 is located in the communicating groove formed by the limiting groove 72, the rotating groove 73 and the guide groove 74. A pressure-bearing spring 78 is provided between the receiving column 43 and the lifting table 42;

[0057] The rotor feeding mechanism 3 includes a telescopic push rod 81 and a rotor connecting sleeve 82. The cylinder part of the telescopic push rod 81 is fixed on the device bracket 1, and the rotor connecting sleeve 82 is fixed at the output end of the telescopic push rod 81;

[0058] When positioning the stator core, the telescopic push rod 81 is used to push the rotor connection sleeve 82 downward, so that the rotor connection sleeve 82 presses down on the bearing column 43. Under the action of pressure, the bearing column 43 drives the convex column 77 to move. When the convex column 77 moves down to the notch at the end of the limit groove 72 and the guide groove 74, guided by the inclined plane 75 on the side wall of the rotation groove 73, the whole bearing column 43 rotates. As the telescopic push rod 81 retracts, the pressure exerted by the rotor connection sleeve on the bearing column 43 decreases. At this time, under the action of the pressure-bearing spring 78, the bearing column 43 will be pushed upward. The convex column 77 on the side wall of the bearing column 43 enters the adjacent guide groove 74 or limit groove 72 under the guidance of the connection surface 76 between the guide groove 74 and the limit groove 72. Since the length of the guide groove 74 is much longer than that of the limit groove 72, when the convex column 77 is located in the guide groove 74, under the action of the pressure-bearing spring 78, the convex column 77 is pushed to the top of the guide groove 74, thereby raising the bearing column 43 by a distance equal to the guide groove 74. When the convex column 77 is located in the limit groove 72, restricted by the limit groove 72, the bearing column 43 will only rise by a distance equal to the limit groove 72. Thus, after the position of the convex column 77 is switched between the guide groove 74 and the limit groove 72, the height adjustment of the bearing column 43 is realized;

[0059] The support frame 44 includes a first connecting rod 91, a second connecting rod 92, a connecting column 93, a support wheel 94, and a sliding ring 95. The first connecting rod 91 is hinged to the upper end of the bearing column 43. One end of the connecting column 93 is hinged to the first connecting rod 91. The support wheel 94 is rotatably installed on the connecting column 93. One end of the second connecting rod 92 is hinged to the other end of the connecting column 93. The other end of the second connecting rod 92 is hinged to the sliding ring 95. The sliding ring 95 is slidably sleeved on the bearing column 43. A hollow cavity 96 is provided at the upper end of the bearing column 43. A support spring 97 is installed inside the hollow cavity 96. A cooperation block 98 is provided at the upper end of the support spring 97. Through grooves 99 are provided on both side walls of the hollow cavity 96. Both ends of the cooperation block 98 pass through the through grooves 99. The sliding ring 95 is located above the cooperation block 98 and is closely arranged against the cooperation block 98. A top column 100 is slidably installed on the bearing column 43. The top column 100 is inserted into the hollow cavity 96. The lower end of the top column 100 contacts the cooperation block 98;

[0060] A rotor docking sleeve 101 is provided at the upper end of the top column 100;

[0061] When positioning the stator, the telescopic push rod 81 extends, causing the rotor connection sleeve 82 to contact the rotor docking sleeve 101. The rotor docking sleeve 101 presses against the ejector pin 100. As the support spring 97 contracts under the pressure, when the deformation of the support spring 97 tends to reach the maximum stroke, the rotor connection sleeve 82 will push the receiving post 43 downward, causing the convex post 77 on the receiving post 43 to displace into the guide groove 74. As the telescopic push rod 81 retracts, the pressure of the rotor connection sleeve 82 on the rotor docking sleeve 101 decreases. The receiving post 43 moves upward under the action of the pressure-bearing spring 78, causing the receiving post 43 to move upward and insert into the inner cavity of the stator. As the rotor connection sleeve 82 separates from the rotor docking sleeve 101, the rotor connection sleeve 82 no longer exerts pressure on the rotor docking sleeve 101. At this time, the cooperation block 98 and the ejector pin 100 move upward under the action of the support spring 97. The cooperation block 98 pushes the slip ring 95 upward, and the slip ring 95 pushes the first connecting rod 91, the second connecting rod 92, and the connecting column 93 to deflect, thereby expanding the connecting column 93, causing the support wheel 94 on the connecting column 93 to contact the inner cavity of the stator. Under the action of the support wheel 94, the whole stator is driven to deflect to determine the stator axis;

[0062] After completing the positioning of the stator axis, one end of the rotor is placed into the rotor docking sleeve 101, and the other end is placed into the rotor connection sleeve 82. The telescopic push rod 81 is used to move downward, pushing the rotor connection sleeve 82, the rotor, and the rotor docking sleeve 101 to move together. Due to the buffering of the support spring 97 and the pressure-bearing spring 78, the buffering of the rotor connection sleeve 82 and the rotor docking sleeve 101 on the stator can also be reduced.
