Description

Technical Field

[0001] The present application relates to the technical field of magnetic steel assembly equipment, and in particular to a surface mounted magnetic steel assembly guide tooling. Background Art

[0002] In the manufacturing process of permanent magnet motors, surface mounted magnets are widely used as a common method to achieve efficient motor performance. However, in the actual assembly process, due to the strong magnetism of magnets, the magnets will be subject to a large magnetic attraction when they are close to the rotor core, which will not only increase the labor intensity of workers, but also may cause problems such as magnet breakage and difficulty in cleaning, thereby affecting the overall quality and operating performance of the motor. Therefore, how to improve the efficiency and safety of the magnet assembly process has become one of the key issues that need to be urgently solved in the field of motor manufacturing.

[0003] At present, there are two common methods in the assembly process of surface mounted magnets: one is manual assembly, which directly places the magnet manually at the specified position of the core; the other is to use simple clamping tools for assembly. Although the manual assembly method has low equipment investment costs, workers need to expend a lot of effort to overcome the suction of the magnet during operation. It is very easy for the magnet to fall off and be adsorbed on the rotor core or other magnets, which not only easily causes the magnet to break, but also makes the cleaning work cumbersome. Although the method of using clamping tools can reduce some of the operational difficulties, it still cannot effectively solve the problems of magnet breakage and incomplete cleaning.

[0004] Traditional manual magnet assembly methods and simple clamping tools fail to provide effective magnetic isolation measures and fail to prevent the strong suction force between the magnet and the iron core or other magnets, resulting in easy swinging and adsorption during the magnet assembly process, which in turn causes magnet breakage and difficulty in cleaning subsequent magnet residues, bringing great adverse effects on motor production and quality. Summary of the invention

[0005] In order to reduce the suction force of the magnet on the rotor surface, prevent the magnet from being unstable when held, and reduce the risk of the magnet breaking, the present application provides a surface mounted magnet assembly guide tooling.

[0006] The present application provides a surface mounted magnetic steel assembly guide tool, which adopts the following technical solution: A surface mounted magnetic steel assembly guide tool comprises a guide rod and two side plates, wherein the guide rod is located between the two side plates, the distance between the two side plates is not less than the width of the magnetic steel, the upper end surface of the side plate is located on the side of the upper end surface of the guide rod away from the lower end surface of the guide rod, an inclined surface is provided at one end of the guide rod, and the length of the guide rod gradually decreases from top to bottom along the inclined surface, a support rod is fixedly provided at the position of the upper end surface of the guide rod, the upper end surface of the support rod is flush with the upper end surface of the guide rod, the lower end surface of the support rod and the lower end of the side plate are both located between the upper end surface and the lower end surface of the guide rod, the width of the support rod and the guide rod are the same and not greater than the width of the magnetic steel slot opened on the corresponding rotor core, the edge line where the inclined surface intersects with the lower end surface of the guide rod is located on the plane where the side of the side plate close to the support rod is located, and the guide rod, the support rod and the two side plates are all made of non-magnetic or weakly magnetic materials.

[0007] By adopting the above technical solution, the width of the guide rod is not greater than the width of the corresponding magnetic steel slot opened on the rotor core, which facilitates the accurate positioning of the guide rod and the support rod in the magnetic steel slot. The distance between the two side plates is not less than the width of the magnetic steel, ensuring that the magnetic steel can be accurately placed on the guide rod and effectively positioned. When the magnetic steel is placed on the upper end surface of the guide rod, the two side plates limit its two sides so that it can slide along the guide rod to prevent the magnetic steel from shifting during the placement process. During the placement of the magnetic steel, the lower edge line of the support rod and the lower edge line of the inclined surface are tightly fitted with the magnetic steel slot surface of the rotor core, so that the upper end surface of the guide rod is in an inclined state, so that the magnetic steel can slide smoothly along the guide rod and the support rod, reducing the risk of the magnetic steel being mistakenly attracted to other slots or magnets during assembly. The guide rod, support rod and two side plates are all made of non-magnetic or weakly magnetic materials to increase the gap between the magnet and the magnet slot, weaken the magnetic attraction between the magnet and the magnet slot surface, and effectively prevent the magnet from being quickly adsorbed on the surface of the rotor core, causing it to break and the problem of fragments being difficult to remove, reducing the losses caused by magnet breakage, and also avoiding motor quality problems caused by incomplete cleaning of residual fragments.

[0008] Optionally, two sliding rods passing through the side plates are fixed on both sides of the guide rod along the length direction, and the side plates are slidably connected to the sliding rod along the axis direction of the sliding rod.

When the elastic member is in a natural state, the side plate abuts against the guide rod.

[0009] By adopting the above technical solution, when the width of the magnet placed between the two side plates is large, the side plates are pushed outward to move along the sliding rod. When the magnet is installed on the rotor core, the side plates return to the state of abutting against the guide rod under the elastic force of the elastic member, so that the tooling can adjust the distance between the side plates according to the magnets of different widths, thereby improving the adaptability of the tooling to magnets of different specifications, reducing the difficulty of the magnet assembly process, and effectively preventing the risk of the magnet falling off due to size mismatch.

[0010] Optionally, the guide rod is provided with a through groove, in which a gear rotatably connected to the guide rod is provided, each side plate is fixedly connected with a rack meshing with the gear, the rack is slidably connected to the guide rod along the axis direction of the sliding rod, and the two racks are evenly arranged along the circumference of the gear.

[0011] By adopting the above technical solution, the sliding of one side plate drives the rack connected to it to slide, the rack drives the gear to rotate, and the gear drives the other rack to slide in the opposite direction, thereby realizing the synchronous movement of the two side plates, so that the magnet placed between the two side plates is always located in the center position, which is convenient for the guide rod to be inserted into the magnet slot of the rotor core, so that the magnet placed between the two side plates always maintains the center position, which is convenient for the magnet to slide smoothly into the magnet slot, avoiding assembly obstacles caused by misalignment, and improving assembly accuracy and work efficiency.

[0012] Optionally, a card plate is provided on the side of the side plate close to the guide rod, and both the guide rod and the support rod are provided with a card slot adapted to the card plate. When the elastic member is in a natural state, the card plate is located in the card slot and the outer side surfaces of the card plate are flush with the outer side surfaces of the guide rod.

[0013] By adopting the above technical solution, the clamping plate can move with the side plate to adapt to the rotor core magnetic steel slots of different widths, so that the magnetic steel can fall into the magnetic steel slot along the guide rod and the support rod, thereby improving the adaptability of the tooling.

[0014] Optionally, the upper end of the side plate close to the guide rod is chamfered.

[0015] By adopting the above technical solution, the chamfer on the upper end of the side plate can better guide the magnet to be placed between the two side plates, which is convenient for positioning and assembling the magnet and improves assembly efficiency and safety.

[0016] Optionally, a displacement assembly is provided on one side of the guide rod, and the displacement assembly includes a support frame, a first lifting cylinder, a slider, a slide rail and a rotating cylinder. The support frame is located on the side of the side plate away from the guide rod, the first lifting cylinder body is fixedly connected to the support frame, the telescopic shaft end of the first lifting cylinder is fixedly connected to the lower end surface of the slide rail, the slider is slidably connected to the slide rail along the axis direction of the rotor, the end of the slider away from the guide rod is fixedly connected to the rotating cylinder body, and the output end of the rotating cylinder is fixedly connected to the end of the guide rod away from the support rod.

[0018] Optionally, a top plate and a push-pull cylinder are provided on the upper end surface of the guide rod, the width of the top plate is not greater than the width of the guide rod and the top plate is located between the two side plates, the push-pull cylinder is located on the side of the top plate away from the support rod, the telescopic shaft end of the push-pull cylinder is fixedly connected to the top plate, and a pressure plate is provided on the upper end surface of the top plate, and one end of the pressure plate along the length direction of the guide rod is located on the side of the top plate away from the push-pull cylinder.

[0019] By adopting the above technical solution, the pressure plate limits the upper end surface of the magnet, and uses the push-pull cylinder to push the top plate to smoothly push the magnet into the magnet groove, reducing the possibility of shaking of the magnet during the pushing process, thereby avoiding the phenomenon of magnet breakage or dislocation, improving assembly accuracy and ensuring the integrity of the magnet, further improving assembly accuracy.

[0020] Optionally, a second lifting cylinder is provided on the side of the top plate away from the support rod, and the pressure plate is located at one end of the top plate close to the push-pull cylinder along the length direction of the guide rod and is fixedly connected to the telescopic shaft end of the second lifting cylinder.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] The present application discloses a surface mounted magnetic steel assembly guide tool.

[0032] Example 1 Reference Figure 1 The embodiment of the present application provides a surface mounted magnet assembly guide tool, including a guide rod 1 and two side plates 2. The guide rod 1 is located between the two side plates 2. The distance between the two side plates 2 is not less than the width of the magnet, ensuring that the magnet can be accurately placed on the guide rod 1 and effectively positioned. The upper end surface of the side plate 2 is located on the side of the upper end surface of the guide rod 1 away from the lower end surface of the guide rod 1. When the magnet is placed on the upper end surface of the guide rod 1, the two side plates 2 limit its two sides so that it can slide along the guide rod 1 to avoid the magnet from shifting during the placement process.

[0033] Reference Figure 2 , an inclined surface 11 is provided at one end of the guide rod 1, and the length of the guide rod 1 gradually decreases from top to bottom along the inclined surface 11. A support rod 12 is fixedly provided at the upper end of the inclined surface 11 of the guide rod 1. The guide rod 1 and the support rod 12 are integrally formed. The guide rod 1, the support rod 12 and the two side plates 2 are all made of non-magnetic or weakly magnetic materials. The upper end surface of the support rod 12 is flush with the upper end surface of the guide rod 1. The lower end surface of the support rod 12 and the lower end of the side plate 2 are both located between the upper end surface and the lower end surface of the guide rod 1. The width of the support rod 12 and the guide rod are the same and not greater than the width of the magnetic steel slot opened on the corresponding rotor core, which facilitates the accurate positioning of the guide rod and the support rod 12 in the magnetic steel slot. The edge line where the inclined surface 11 intersects with the lower end surface of the guide rod 1 is located on the plane where the side of the side plate 2 close to the support rod 12 is located.

[0034] The guide rod 1, the support rod 12 and the two side plates 2 are all made of non-magnetic or weakly magnetic materials, which increase the gap between the magnet and the magnet slot, weaken the magnetic attraction between the magnet and the surface of the magnet slot, and effectively prevent the magnet from being quickly adsorbed on the surface of the rotor core, causing the magnet to break and the problem of fragments being difficult to remove, thereby reducing the losses caused by the breakage of the magnet and avoiding motor quality problems caused by incomplete cleaning of residual fragments.

[0035] During the specific operation, when assembling the magnet, the operator holds the end of the guide rod 1 away from the support rod 12, and the lower edge line of the support rod 12 and the lower edge line of the inclined surface 11 are tightly fitted with the magnet slot surface of the rotor core, so that the upper end surface of the guide rod 1 is in an inclined state to form a slope, and the magnet is placed on the guide rod 1, and the magnet is slowly pushed to make the magnet slowly slide into the magnet slot, so that the magnet can slide smoothly along the guide rod 1 and the support rod 12, reducing the risk of being mistakenly attracted to other slots or magnets during the magnet assembly process.

[0036] Example 2 Reference Figure 3 The difference between this embodiment and the above-mentioned embodiment is that a sliding rod 13 mechanism and a displacement device are added on both sides of the guide rod 1.

[0037] Reference Figure 4 Two slide bars 13 passing through the side plates 2 are fixedly provided on both sides of the guide rod 1 along the length direction. The slide bars 13 themselves are made of high-strength alloy steel, and the surface is hardened to enhance the wear resistance so as to balance the relationship between friction resistance and load-bearing capacity.

[0038] Reference Figure 5 A clamping plate 21 is provided on the side of the side plate 2 close to the guide rod 1, and a clamping groove adapted to the clamping plate 21 is provided on both the guide rod 1 and the support rod 12. The side plate 2 drives the clamping plate 21 to slide and connect with the slide rod 13 along the axis direction of the slide rod 13, and the connection between the slide rod 13 and the side plate 2 adopts a rolling bearing structure, which can ensure that the two can slide relatively freely and prevent the side plate 2 from sliding down under the action of gravity.

[0039] Reference Figure 4 , a baffle 14 is provided at one end of the slide bar 13 away from the guide bar 1, and an elastic member 15 is provided between the baffle 14 and the side plate 2 and sleeved on the outside of the slide bar 13. The elastic member 15 is made of high-quality spring material and has a moderate preload force, which can ensure that the side plate 2 can be quickly reset and resist a certain degree of external impact load. When there is no magnetic steel between the two side plates 2, the elastic member 15 is in a natural state. At this time, the side plate 2 is in contact with the guide bar 1, the card plate 21 is located in the card slot, and the outer side surface of the card plate 21 is flush with the outer side surface of the guide bar 1, that is, the outer surface of the support rod 12 and the guide plate is in the same plane as the outer surface of the card plate 21, and there is no height difference between them.

[0040] Reference Figure 4, a chamfer 22 is provided at the upper end of the side plate 2. This design allows the magnet to be better guided into between the two side plates 2, reduces the probability of scratching the magnet, avoids damage or deformation of the magnet during assembly, facilitates the positioning and assembly of the magnet, and improves assembly efficiency and safety. The angle of the chamfer 22 can be adjusted according to actual needs, such as being set to about 45° to ensure that the magnet will not get stuck during introduction.

[0041] Reference Figure 4 and Figure 5 In addition, the guide rod 1 is provided with a through slot 16, in which a gear 17 is provided for rotation with the guide rod 1. Each side plate 2 is fixedly connected with a rack 18 meshing with the gear 17. The rack 18 is slidably connected with the guide rod 1 along the axis direction of the slide rod 13, and the two racks 18 are evenly arranged along the circumference of the gear 17. The gear 17 is connected with the guide rod 1 through a small shaft, and the material can be selected from high-strength alloy steel or hard plastic to ensure the stability and durability of the gear 17 during rotation. The rack 18 is fixedly connected with the side plate 2, and the material is also high-strength alloy steel or hard plastic, so as to ensure that the rack 18 is well matched with the guide rod 1 during the sliding process. The design of the gear 17 and the rack 18 enables one side plate 2 to slide and drive the rack 18 connected thereto to slide, the rack 18 drives the gear 17 to rotate, and the gear 17 drives the other rack 18 to slide in the opposite direction, thereby realizing the synchronous movement of the two side plates 2, so that the magnet placed between the two side plates 2 is always located in the center position, so that after the guide rod 1 is inserted into the magnet slot of the rotor core, the magnet placed between the two side plates 2 always remains in the center position, so that the magnet can slide smoothly into the magnet slot, avoiding assembly obstacles caused by misalignment, and improving assembly accuracy and work efficiency.

[0042] Reference Figure 3 A displacement assembly 3 is provided on one side of the guide rod 1. The displacement assembly 3 includes a support frame 31, a first lifting cylinder 32, a slider 33, a slide rail 34 and a rotating cylinder 35. The support frame 31 is located on the side of the side plate 2 away from the guide rod 1. The support frame 31 is welded with high-strength steel and can withstand various dynamic loads during the operation of the entire device. The cylinder body of the first lifting cylinder 32 is fixedly connected to the support frame 31, and the telescopic shaft end of the first lifting cylinder 32 is fixedly connected to the lower end surface of the slide rail 34. The first lifting cylinder 32 drives the slide rail 34 to rise and fall, thereby driving the guide rod 1 to rise and fall. It can adapt to the installation requirements of rotor core magnets of different sizes, and enhances the applicability of the tooling. The slider 33 is slidably connected to the slide rail 34 along the axis of the rotor. The end of the slider 33 away from the guide rod 1 is fixedly connected to the cylinder body of the rotating cylinder 35. The output end of the rotating cylinder 35 is fixedly connected to the end of the guide rod 1 away from the support rod 12. The rotating cylinder 35 can drive the guide rod 1 to rotate and move. When rotating, the guide rod 1 can be tilted, which is convenient for the magnet to fall into the magnet groove. When moving, it can adapt to the installation of magnets of rotor cores of different sizes, thereby improving the adaptability and assembly accuracy of the tooling.

[0043] In a specific implementation, the sliding mode of the slider 33 and the slide rail 34 can be achieved by opening a slide groove on the slide rail 34, with the lower end of the slider 33 in the slide groove, and setting a lead screw to be rotatably connected to the slide rail 34. The lead screw passes through the slider 33 and is threadedly connected to the slider 33. A motor is used to drive the lead screw to rotate, thereby driving the slider 33 to slide on the slide rail 34.

[0044] Reference Figure 5 and Figure 6 A top plate 4 and a push-pull cylinder 5 are provided on the upper end surface of the guide rod 1. The width of the top plate 4 is not greater than the width of the guide rod and the top plate 4 is located between the two side plates 2. The push-pull cylinder 5 is located on the side of the top plate 4 away from the support rod 12. The telescopic shaft end of the push-pull cylinder 5 is fixedly connected to the top plate 4. A pressing plate 41 is provided on the upper end surface of the top plate 4. One end of the pressing plate 41 along the length direction of the guide rod 1 is located on the side of the top plate 4 away from the push-pull cylinder 5.

[0045] Reference Figure 6 A second lifting cylinder 42 is provided on the side of the top plate 4 away from the support rod 12, and a pressing plate 41 is located at one end of the top plate 4 close to the push-pull cylinder 5 along the length direction of the guide rod 1 and is fixedly connected to the telescopic shaft end of the second lifting cylinder 42. The second lifting cylinder 42 can provide the top plate 4 with up and down movement, thereby adapting to magnetic steels of different heights, further enhancing the adaptability of the tooling.

[0046] During the specific operation, the first lifting cylinder 32 drives the slide rail 34 to rise and fall, and the rotating cylinder 35 drives the guide rod 1 to move by telescoping to adapt to rotor cores of different diameters, thereby improving the adaptability of the tooling; when the guide rod corresponds to the position of the magnetic steel slot on the rotor core, the rotating cylinder 35 rotates the guide rod 1, so that the lower edge line of the support rod 12 and the lower edge line of the inclined surface 11 are closely fitted with the magnetic steel slot surface of the rotor core, so that the upper end surface of the guide rod 1 is in an inclined state, so that the magnetic steel can slide smoothly along the guide rod 1 and the support rod 12, reducing the risk of the magnetic steel being mistakenly attracted to other slots or magnetic steel during assembly; then the magnetic steel is placed between the two side plates 2, and the two side plates 2 drive the clamping plate 21 to move in the same direction according to the width of the magnetic steel. The second lifting cylinder 42 drives the pressure plate 41 to press against the upper end surface of the magnet. The top plate 4 can be lifted and lowered under the action of the second lifting cylinder 42, and can adapt to magnets of different heights, further improving the adaptability of the tooling, ensuring that the magnet remains stable during the assembly process, and avoiding breakage or misalignment caused by the shaking of the magnet. The slider 33 drives the guide rod 1 to move on the slide rail 34 along the axis of the rotor core, thereby realizing the automation of the magnet installation and improving the installation efficiency.
