Description

Technical Field

[0001] The invention relates to the technical field of rotor assembly, and in particular to a quick assembly tool for an outer rotor permanent magnet motor. Background Art

[0002] A permanent magnet motor is a motor that uses a permanent magnetic field generated by a permanent magnet to operate the motor. Compared to traditional motors, such as DC motors or AC asynchronous motors, permanent magnet motors usually have higher efficiency and simpler structures. The current permanent magnet motor assembly method requires the rotor and permanent magnet to be bonded together. To avoid excessive rotation speed causing the position of the permanent magnet and rotor to shift, manufacturers use strong glue to bond the two together.

[0003] However, due to the strong magnetic force of the permanent magnet, the permanent magnet will collide violently with the rotor, which will not only pose a risk of pinching the worker's hands, but will also cause damage to the permanent magnet or rotor, reducing its service life; not only that, excessive magnetic force will also cause the permanent magnet to squeeze out the glue between it and the rotor, causing the glue to be too thin and insufficient to provide sufficient adhesion, resulting in certain safety hazards in the manufactured motor.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] See also Figure 1-4 , a quick assembly tool for an outer rotor permanent magnet motor, comprising an outer rotor body 1 and a permanent magnet 2, a positioning clamping component 3 responsible for fixing the outer rotor body 1 is arranged on the outside of the outer rotor body 1, the positioning clamping component 3 comprises a pair of clamping blocks 31, an outer end of the clamping block 31 is provided with a movable groove 32 and an installation groove 33, the movable groove 32 and the installation groove 33 are connected to each other, a transmission component 4 is slidably arranged inside the movable groove 32, the transmission component 4 comprises a transmission belt 41, the outer end of the transmission belt 41 is fixedly connected to a limiting component 5, the limiting component 5 is used to limit the permanent magnet 2 at a set distance outside the outer rotor body 1, the outer end of the transmission belt 41 is provided with a buffer component 6, the buffer component 6 is used to effectively buffer the limiting component 5 when it falls, the limiting component 5 is provided with an automatic shrinking component 7, the automatic shrinking component 7 is used to automatically shrink when the limiting component 5 moves down to the lowest point.

[0037] See also Figure 1The positioning and clamping component 3 also includes a telescopic bracket 34, which is a pair of L-shaped plates 341. The pair of L-shaped plates 341 are connected by a freely retractable friction rod 342, and a friction hole is opened at the side end of one of the L-shaped plates 341. The friction rod 342 is connected to the friction hole by a damping friction. The side end of the L-shaped plate 341 is fixedly connected with a telescopic rod 35 with adjustable length. The top end of the telescopic rod 35 is fixedly connected to the clamping block 31. The side end of the L-shaped plate 341 is also fixedly connected with a smooth support shaft 36. The outer rotor body 1 needs to be initially sleeved on the support shaft 36.

[0038] Initially, the staff first sleeves the outer rotor body 1 on one of the support shafts 36, and then pushes the other L-shaped plate 341, so that a pair of support shafts 36 are both extended into the interior of the outer rotor body 1, and at the same time, a pair of clamping blocks 31 are also close to the outer end of the outer rotor body 1. Then, the staff starts to apply a layer of glue on the top of the outer rotor body 1 with a hose. Finally, the permanent magnet 2 to be adsorbed is placed on the limiting component 5. Under the strong suction force of the permanent magnet 2, the permanent magnet 2 quickly moves down with the limiting component 5. When the limiting component 5 moves down to the set position, the permanent magnet 2 stops. At this time, the permanent magnet 2 is bonded to the glue, and there is a set gap between it and the outer rotor body 1, and a layer of glue is formed on this gap, which can effectively prevent the permanent magnet 2 from squeezing out the glue under the action of magnetic force, which not only wastes glue, but also greatly reduces the viscosity between the permanent magnet 2 and the outer rotor body 1, and also avoids the collision between the permanent magnet 2 and the outer rotor body 1, which damages both.

[0039] Subsequently, the outer rotor body 1 is rotated, and then the second permanent magnet 2 is bonded.

[0040] See also Figure 5 The transmission component 4 also includes a pair of fixed plates 42 fixedly connected to the bottom of the movable groove 32, a pair of pulleys 43 are rotatably connected between the pair of fixed plates 42, the pulleys 43 are transmission-connected to the transmission belt 41, and a rotating rod 44 is fixedly connected to the outer end of the pulley 43.

[0041] See also Figure 5-6 The buffer component 6 includes a liquid storage tank 61 with an installation groove 33, the liquid storage tank 61 is rotatably connected to a threaded rod 62 inside, the threaded rod 62 is externally threadedly connected to a screw sleeve 63, the top of the screw sleeve 63 is fixedly connected to a piston plate 64, the outer end of the liquid storage tank 61 is fixedly connected to a water outlet pipe 65, the outer end of the screw sleeve 63 is fixedly connected to a guide bar, and the outer end of the liquid storage tank 61 is also provided with a guide hole 55 that is compatible with the guide bar. By providing the guide bar and the guide hole 55, the rotation of the screw sleeve 63 can be effectively prevented.

[0042] Specifically, during the downward movement of the limiting component 5, the transmission belt 41 will move with it, and the transmission belt 41 will rotate the pulley 43 through friction, so that the rotating rod 44 will continue to rotate. During the rotation of the rotating rod 44, the threaded rod 62 is forced to rotate. Due to the threaded connection between the threaded rod 62 and the threaded sleeve, the threaded sleeve will continue to move and push the liquid on one side of the piston plate 64 out through the outlet pipe 65. The liquid pressure generated by the liquid entering the outlet pipe 65 can effectively slow down the rotation speed of the rotating rod 44, thereby reducing the movement speed of the transmission belt 41, so that the impact force brought by the permanent magnet 2 carrying the limiting component 5 down is effectively buffered, avoiding excessive impact force and damaging the limiting component 5 or the permanent magnet 2.

[0043] See also Fig. 9 In an embodiment further provided by the present invention, a trigger component 8 is provided under the buffer component 6, and the trigger component 8 is used to trigger the automatic contraction component 7 to start when the limit component 5 moves down to the lowest position. The trigger component 8 includes a spare box 81 fixedly connected to the side end of the fixed plate 42, and a first movable hole is opened on the top of the spare box 81. A partition plate 82 is fixedly connected to the inner wall of the spare box 81, and a second movable hole is opened on the partition plate 82. A connecting pipe 83 is provided inside the spare box 81, and the connecting pipe 83 is respectively movable through The connecting tube 83 passes through the first movable hole and the second movable hole, and the outer end near the top is fixedly connected to a pressing block 84, and the outer end of the pressing block 84 is fixedly connected to a first bent rod 85. A first reset member 86 is fixedly connected between the outer end of the first bent rod 85 and the top of the spare box 81. The first reset member 86 is a compression spring. The outer end of the spare box 81 is provided with a vent hole 87 located below the partition plate 82. When the limiting component 5 moves to the lowest point, the connecting tube 83 is pushed downward, so that the upper and lower chambers of the partition plate 82 are connected to each other.

[0044] See also Fig.10 Furthermore, a liquid outlet hole 88 is opened on the connecting tube 83, and the liquid outlet hole 88 is initially located above the partition plate 82. The bottom end of the connecting tube 83 is in a blocked state. A plurality of through holes 89 are opened on the connecting tube 83, and the through holes 89 are always located above the partition plate 82 during the up and down movement of the connecting tube 83.

[0045] During the downward movement of the limiting component 5, the threaded rod 62 continues to rotate, and most of the liquid is transported to the top of the partition plate 82 through the piston plate 64. At this time, the liquid outlet 88 is located above the partition plate 82, and its upper and lower chambers are not connected. When the limiting component 5 moves down to the lowest point, it will push the first curved rod 85 to move downward, and the first curved rod 85 moves downward with the connecting tube 83 through the pressing block 84. At this time, the liquid outlet 88 moves down to the bottom of the partition plate 82. Since the air vent 87 is opened, the air pressure below the partition plate 82 is connected to the external atmospheric pressure, and the liquid will slowly fall from the liquid outlet 88 to the bottom, which is convenient for the subsequent drive of the automatic contraction component 7 to start.

[0046] See also Fig.11 The automatic retracting component 7 includes a sliding plate 71 slidably connected to the inner wall of the spare box 81, the outer wall of the sliding plate 71 is wrapped with a sealing sleeve, the bottom of the sliding plate 71 is fixedly connected to a pushing block 72, the outer end of the spare box 81 is provided with a third movable hole, the inner wall of the third movable hole is slidably connected to a second curved rod 73, one end of the second curved rod 73 is fixedly connected to a pressure block 74, and the other end is fixedly connected to a pressure plate 75, one side of the pushing block 72 and the pressure block 74 are both in an inclined state, the outer end of the rotating rod 44 is fixedly sleeved with a spring roll 76, when the sliding plate 71 moves down to the lowest point, it pushes the pressure plate 75 to move, so that the limiting component 5 shrinks.

[0047] See also Figure 8 The limiting component 5 includes a hollow plate 51 fixedly connected to the outer end of the transmission belt, the outer end of the hollow plate 51 is fixedly connected to an arc plate 52, the outer end of the arc plate 52 is fixedly connected to a plurality of limiting rods 53, the outer ends of the limiting rods 53 are sprayed with an anti-stick coating, such as Teflon coating; or coated with an anti-stick film, such as polytetrafluoroethylene, silicone rubber, polyethylene, etc., which effectively prevents the limiting rods 53 from being stuck by glue, and elastic cotton is fixedly connected between the inside of the hollow plate 51 and the outer end of the arc plate 52, and a force-bearing plate 54 is fixedly connected to the bottom of the arc plate 52, and the outer end of the force-bearing plate 54 conflicts with the pressing plate 75, and a guide hole 55 is opened on the fixed plate 42, and a pair of sliding rods 56 are fixedly connected to the outer end of the hollow plate 51, and when the sliding rod 56 moves down to the lowest point, it conflicts with the first curved rod 85.

[0048] During the falling process of the liquid, under the action of the gravity of the liquid, the sliding plate 71 drops rapidly (the aperture size of the liquid outlet hole 88 determines the descending speed of the sliding plate 71) until the sliding plate 71 brings the pushing block 72 to push the pressure block 74 to move, causing the second curved rod 73 to move as well, and finally causing the second curved rod 73 to contract the limiting component 5 through the pressure plate 75. After the contraction, the limiting component 5 loses the pressure of the permanent magnet 2 and begins to rise under the action of the spring coil 76, facilitating the subsequent adhesion of the second permanent magnet 2.

[0049] In actual use, a hot air blower can be used to align the adhesive layer to facilitate rapid curing of the adhesive layer.

[0050] The mainspring roll 76 serves the purpose of resetting the limit component 5. Initially, the limit component 5 is located at the top. When it is pressed down to the lowest point by the permanent magnet 2, the mainspring roll 76 is pulled. After the pressure is lost, the rotating rod 44 rotates with the pulley 43, causing the transmission belt 41 to automatically move and reset, thereby achieving the effect of automatic resetting of the limit component 5.

[0051] See also Figure 6 or Fig. 9 The outer end of the liquid storage tank 61 is fixedly connected with a water inlet pipe 66, one end of which is fixedly passed through the interior of the spare box 81 and is located below the partition plate 82. A second reset member 67 is fixedly connected between the sliding plate 71 and the inner bottom of the spare box 81.

[0052] By setting the second reset member 67, when the liquid above the sliding plate 71 is pumped away, the sliding plate 71 rises under the action of the second reset member 67, which not only enables the sliding plate 71 to return to the initial position, but also enables the water inlet pipe 66 to always pump water and keep the water level line unchanged.

[0053] A suction switching component 9 is also provided inside the liquid storage tank 61, and the suction switching component 9 includes a switching plate 91 rotatably connected to the inner wall of the liquid storage tank 61, an elastic rope is fixedly connected between the switching plate 91 and the outer end of the liquid storage tank 61, a connecting hole 92 is opened on the switching plate 91, a touch rod 93 is fixedly connected to the side end of the piston plate 64, and an arc-shaped ramp plate 94 is fixedly connected to the switching plate 91. When the touch rod 93 squeezes the arc-shaped ramp plate 94, the switching plate 91 rotates.

[0054] When the piston plate 64 moves, it will also move with the feeler rod 93. The top of the feeler rod 93 is in a smooth hemispherical shape. After contacting the arc-shaped ramp plate 94, due to the curved surface with crests and troughs on the arc-shaped ramp plate 94, it begins to rotate with the switching plate 91 after being subjected to pressure. Initially, the connecting hole 92 is aligned with the water outlet pipe 65. When the switching plate 91 moves to the end point, the connecting hole 92 is aligned with the water inlet pipe 66. At this time, the rotating rod 44 rotates in the opposite direction with the threaded rod 62, so that the piston plate 64 also starts to move back, and the liquid under the partition plate 82 is pumped back into the liquid storage tank 61 through the water inlet pipe 66, and the liquid can be squeezed into the water outlet pipe 65 again later.

[0055] Specifically, the outer end of the switching plate 91 is fixedly connected with a plurality of one-way elastic teeth 95, and a limiting gear 96 is slidably connected near the inner bottom of the liquid storage tank 61. An elastic rope is fixedly connected between the outer end of the switching plate 91 and the inner wall of the liquid storage tank 61, a traction rope 97 is fixedly connected between the piston plate 64 and the limiting gear 96, and an elastic sponge is fixedly connected between the limiting gear 96 and the liquid storage tank 61.

[0056] Initially, the switching plate 91 rotates, the one-way elastic tooth piece 95 is compressed and bent, and rotates with the switching plate 91. When the piston plate 64 is reset, the elastic rope is bent, and the switching plate 91 no longer rotates. At this time, the water inlet pipe 66 is continuously opened, and the liquid under the partition plate 82 is continuously pumped into the liquid storage tank 61. When the piston plate 64 moves to the initial position, under the pull of the elastic rope, the limit gear 96 is separated from the multiple one-way elastic tooth pieces 95. At this time, there is no constraint of the limit gear 96, and the limit gear 96 is reset. At this time, the water inlet pipe 66 is closed and the water outlet pipe 65 is opened.

[0057] See also Fig.12 The connecting hole 92 is fan-shaped. When the switching plate 91 rotates, the blocking area of ​​the water outlet pipe 65 gradually increases. When the water outlet pipe 65 is completely blocked, the connecting hole 92 rotates to the water inlet pipe 66.

[0058] At the beginning, the outlet of the water outlet pipe 65 is wide open, and then the outlet of the water outlet pipe 65 is gradually blocked, so that the water output of the water outlet pipe 65 gradually decreases. Since the closer the permanent magnet 2 is to the outer rotor body 1, the greater the magnetic force, the required buffering force should also be greater. By gradually narrowing the outlet of the water outlet pipe 65, a greater buffering force can be achieved, so that the permanent magnet 2 can descend more smoothly. When reaching the lowest point, the speed can also be slowly reduced to 0, so that the increased magnetic force and the increased recoil force offset each other, achieving the purpose of stable speed.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
