Description

Technical Field

[0001] The present invention relates to the technical field of motor manufacturing, and in particular to a surface mounted rotor magnetic steel assembly device and an assembly method. Background Art

[0002] At present, for the surface-mounted rotor of the permanent magnet motor, the magnetic steel assembly method is divided according to the direction of the axis during assembly, mainly into two types: vertical assembly of magnetic steel (i.e., the rotor axis is placed vertically) and horizontal assembly of magnetic steel (the rotor axis is placed horizontally). Vertical assembly can be performed using dedicated manual, pneumatic or electric equipment, while for horizontal assembly, most of them are manually pushed or pushed using a jack in conjunction with tooling.

The magnetic steel propulsion device includes a cylinder, a connecting bracket, a push rod, a guide plate and a pad. The defects and shortcomings of the permanent magnet motor surface-mounted magnetic steel assembly tool are: the magnetic steel propulsion device of the tool is detachably mounted on the magnetic steel installation end face of the rotor core through the guide plate, and is directly opposite to a magnetic steel installation groove on the rotor core; after the corresponding magnetic steel block is installed in the installation area of ​​the magnetic steel installation groove, the operator needs to remove the entire magnetic steel propulsion device and then install it at the next assembly position to carry out the magnetic steel installation work of the remaining magnetic steel installation groove of the rotor core.

DETAILED DESCRIPTION

[0042] In order to better explain the present invention and facilitate understanding, the following is a detailed description of the present invention through specific embodiments in conjunction with the accompanying drawings. Figure 1 The orientation is used as a reference.

[0043] Embodiment 1:

[0044] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 , this embodiment provides a surface mounted rotor magnet assembly device, comprising:

[0045] The assembly platform 1 can rotatably support the rotor 5 and position the rotor 5 or release the positioning restriction of the rotor 5. A plurality of magnetic steel mounting grooves 502 are arranged on the circumference of the rotor 5.

[0046] The assembly component 2 is slidably mounted on the assembly platform 1 along the axial direction of the rotor 5, and the assembly component 2 includes a magnetic steel pushing tool 24 located on the assembly component 2, and the magnetic steel pushing tool 24 is provided with a tooth portion 241 for pushing the magnetic steel 503 on the rotor 5 to complete the assembly when the assembly component 2 slides along the axial direction;

[0047] The linear drive device is connected to the bottom of the assembly component 2, and can drive the assembly component 2 and the magnet pushing tool 24 to move axially, so that the tooth portion 241 moves axially synchronously, thereby synchronously pushing the multiple rows of magnets 503 to the magnet installation area. It should be noted that the axial direction of the rotor 5 is parallel to the left-right direction.

[0048] The surface-mounted rotor magnet assembly equipment of this embodiment firstly performs circumferential positioning of the rotor 5 on the assembly platform 1 through the rotor circumferential positioning device, and then drives the assembly component 2 on the assembly platform 1 through the linear drive device. The assembly component 2 then drives the magnet pushing tooling 24 to move laterally. During assembly, the operator does not need to frequently disassemble and assemble the assembly component 2 with great effort, which greatly improves the assembly efficiency.

[0049] Furthermore, the assembly component also includes a rectangular frame axially slidably installed on the assembly platform 1, and the magnet pushing tooling 24 is arranged toward the rotor 5 on at least one beam forming the rectangular frame; at least two teeth 241 are arranged at intervals on the magnet pushing tooling 24, so that the multiple teeth 241 on the magnet pushing tooling 24 can realize the assembly of multiple columns of magnets 503 at one time, which further improves the assembly efficiency of a magnet 503.

[0050] It should be noted that the rotor 5 of this embodiment refers to the rotor 5 in a large permanent magnet motor. Of course, the rotor 5 described in this embodiment may also be a small or medium-sized rotor 5, and is equally applicable.

[0051] like Figure 6 and Figure 7As shown, a plurality of axially extending magnetic steel strips 501 are arranged on the circumferential surface of the rotor 5 of this embodiment, wherein two adjacent magnetic steel strips 501 and the circumferential surface of the rotor 5 enclose a magnetic steel mounting groove 502, each magnetic steel mounting groove 502 corresponds to a magnetic pole to be installed, and the magnetic pole to be installed is composed of a plurality of magnetic steels 503.

[0052] like Figure 2 As shown, the assembly platform 1 includes a frame-shaped platform 11, a first support seat 16 and a second support seat 17. The first support seat 16 is installed on the left side of the upper surface of the frame-shaped platform 11, and the second support seat 17 is installed on the right side of the upper surface of the frame-shaped platform 11. Two rollers 161 are arranged on the upper parts of the first support seat 16 and the second support seat 17, and the two rollers 161 can rotate and support the rotating shaft of the rotor 5.

[0053] In addition, a first positioning hole 162 is formed on the outer side surface of the first support seat 16 , and the rotor circumferential positioning device can be selectively plugged into the first positioning hole 162 .

[0054] Specifically, the axial directions of the two rollers 161 are parallel to the axial direction of the rotor 5, and the two ends of the rotating axis of the rotor 5 are stepped axes and formed with step surfaces. The inner side surface of the support seat 16 can abut against the step surface of the rotor 5 to axially position the rotating axis of the rotor 5. In this way, when the assembly component 2 pushes the magnetic steel 503 axially, the rotor 5 will not move axially.

[0055] It should be noted that the length of the frame-shaped platform 11 should be greater than the length of the support position of the rotor 5, the width should be greater than the yoke diameter of the rotor 5, the height of the support seat 16 should be greater than the yoke radius of the rotor 5, and sufficient distance should be left to prevent the assembled magnetic steel 503 from generating attraction for the assembly platform 1, causing displacement of the assembly platform 1 or the rotor 5.

[0056] Furthermore, the assembly platform 1 further comprises a rotor circumferential positioning device, which can be detachably fixed to the rotating shaft of the rotor 5 and can be selectively connected to the assembly platform 1 to perform circumferential positioning on the rotor 5;

[0057] Combination Figure 1 and Figure 3 As shown, the rotor circumferential positioning device includes a rotating positioning plate 3 and a positioning rod 4. The middle part of the rotating positioning plate 3 is bolted to the end of the rotating shaft of the rotor 5, and the edges of the rotating positioning plate 3 are provided with a plurality of second positioning holes 301 along the circumferential direction. The positioning rod 4 passes through the second positioning holes 301 and the first positioning holes 162, so as to perform circumferential positioning on the rotating positioning plate 3 and the rotor 5.

[0058] It should be noted that the operator can rotate the positioning plate 3 to make each second positioning hole 301 correspond to the first positioning hole 162 respectively, and then insert and fix the positioning rod 4 to perform circumferential limiting. As a result, the magnetic steel mounting groove 502 on the rotor 5 can realize position switching, and correspond to the magnetic steel pushing tooling 24 in turn to push the magnetic steel 503.

[0059] Furthermore, the rotating positioning plate 3 is provided with slots along the circumference thereof, and the slots are used to facilitate the rotation of the operator. The positioning rod 4 is preferably a round rod.

[0060] like Figure 4 As shown, the rectangular frame of this embodiment also includes a bottom plate 21, a crossbeam 23 and two side beams 22. The two ends of the bottom plate 21 are respectively connected to the lower ends of the two side beams 22, and the two ends of the crossbeam 23 are respectively connected to the upper ends of the two side beams 22; a slider 221 is provided at the lower end of the side beam 22, and a guide rail 15 extending in the left-right direction is provided on the upper surface of the frame-shaped platform 11 corresponding to the two side beams 22, and the slider 221 is slidably provided on the guide rail 15; the linear drive device is transmission-connected to the middle of the bottom plate 21, and a magnetic steel tooling 24 is installed in the middle of the crossbeam 23.

[0061] Furthermore, the side beam 22 includes a main beam 222 extending in the vertical direction and an oblique support beam 223 extending in the lower right direction. The upper end of the main beam 222 is connected to the upper end of the oblique support beam 223, and the lower ends of the main beam 222 and the oblique support beam 223 are both slidably connected to the guide rail 15 through a slider 221. It should be noted that the purpose of using the oblique support beam 223 is to enhance the stability of the assembly component 2.

[0062] Preferably, a magnet pushing tool 24 is provided on the crossbeam 23, and four teeth 241 extending downward are provided at the bottom of the magnet pushing tool 24, and each tooth 241 corresponds to a magnet installation slot 502. For example, the number of magnet installation slots 502 on the circumferential surface of the rotor 5 is 24, and the magnet pushing tool 24 of this embodiment needs to be pushed six times, and the rotor 5 needs to switch the assembly position five times to complete the assembly of the magnet 503.

[0063] Furthermore, a polytetrafluoroethylene layer or a rubber layer is attached to the tooth portion 241. The polytetrafluoroethylene layer and the rubber layer are soft materials, which can prevent the tooth portion 241 from hitting the magnetic steel 503.

[0064] Preferably, the magnetic steel pushing tooling 24 is made of non-magnetic materials such as stainless steel and alloy aluminum. Except for the magnetic steel pushing tooling 24, the assembly platform 1, assembly component 2, rotating positioning plate 3 and positioning rod 4 of this embodiment can be made of ordinary carbon steel.

[0065] like Figure 2As shown, the linear drive device of this embodiment is a ball screw drive assembly, which includes a ball nut 211, a first lead screw 14, two motors 12 and two gear boxes 13. The axial direction of the first lead screw 14 is parallel to the guide rail 15, and the outer periphery of the first lead screw 14 is sleeved with a ball nut 211, and the ball nut 211 is fixedly mounted on the bottom plate 21 of the assembly component 2; one of the two motors 12 is connected to one end of the first lead screw 14 through the gear box 13, and the other of the two motors 12 is connected to the other end of the first lead screw 14 through the gear box 13. The purpose of setting two motors 12 in this embodiment is to improve the stability and reliability of the linear drive device, that is, the two motors 12 constitute a double insurance, and even if one motor 12 is damaged, the linear drive device can still work normally.

[0066] like Figure 5 and Figure 6 As shown, the magnetic steel strip 501 is provided with a plurality of through holes along the length direction, and each of the through holes can cooperate with standard fasteners to detachably fix the magnetic steel strip 501 on the outer circumferential surface of the rotor 5. In addition, the cross section of the magnetic steel strip 501 is T-shaped, and the enclosed space formed by the T-shaped magnetic steel strip 501 and the outer circumferential surface of the rotor 5 can clamp the side of the magnetic steel 503 and limit the top surface at the side of the magnetic steel 503. Therefore, in this embodiment, only the magnetic steel positioning tool 6 is required to axially position the magnetic steel 503, and no radial positioning tool is required.

[0067] Specifically, the magnetic steel positioning tool 6 includes an axial baffle 601, a second screw rod 602 and a nylon block 603. The axial baffle 601 is detachably fixed on the side of the core of the rotor 5 and faces the magnetic steel installation slot 502. A threaded hole is provided on the axial baffle 601. The second screw rod 602 is screwed into the threaded hole. The end of the second screw rod 602 is rotated to connect the nylon block 603, and the nylon block 603 can abut the side of the magnetic steel 503. When working, the second screw rod 602 is rotated, and the second screw rod 602 pushes the nylon block 603 to move along the magnetic steel installation slot 502, thereby axially tightening the magnetic steel 503; after tightening, the second screw rod 602 is rotated in the opposite direction, and the second screw rod 602 drives the nylon block 603 to reset and disengage from the magnetic steel 503.

[0068] This embodiment also provides a method for assembling magnetic steel using the surface-mounted rotor magnetic steel assembly equipment, which at least includes the following steps:

[0069] S100 , installing magnetic steel strips 501 : installing a plurality of magnetic steel strips 501 on the circumferential surface of the rotor 5 , thereby forming magnetic steel installation grooves 502 .

[0070] S200, circumferential positioning of the rotor 5: circumferentially positioning the rotor 5 on the assembly platform 1, so that the tooth portion 241 on the magnetic steel pushing tool 24 is directly opposite to the magnetic steel installation groove 502 on the rotor 5. Specifically, the rotor 5 is first placed on the assembly platform 1, and the support position of the rotor 5 is placed on the two support seats 16 of the assembly base 1, and the roller 161 forms a rotation support for the rotation axis of the rotor 5; then the rotating positioning plate 3 is fixedly installed on the end of the rotation axis of the rotor 5, and finally, the positioning rod 4 is used to pass through the second positioning hole 301 and the first positioning hole 162 for circumferential positioning.

[0071] S300, assembling magnetic steel 503: placing multiple magnetic steels 503 into multiple magnetic steel installation grooves 502 of the rotor 5 in a one-to-one correspondence; starting the linear drive device to move the assembly component 2 axially, and pushing the magnetic steel tooling 24 to assemble multiple rows of magnetic steels 503 to the corresponding magnetic steel installation areas at the same time. Specifically, first, apply magnetic steel adhesive to the magnetic steel installation area; second, place multiple magnetic steels 503 into multiple magnetic steel installation grooves 502 of the rotor 5 in a one-to-one correspondence; finally, drive the assembly component 2 to move to the left through the linear drive device, so that the magnetic steel tooling 24 can simultaneously assemble multiple magnetic steels 503 to the corresponding magnetic steel installation areas.

[0072] S400, resetting assembly component 2: starting the linear drive device to move assembly component 2 to the right, away from the magnetic steel 503, and return to the initial position.

[0073] S500 , repeat the above steps S300 to S400 until the assembly of the magnetic steels 503 in the plurality of magnetic steel installation slots 502 is completed.

[0074] S600, rotating the rotor 5 to the next assembly position, repeating the above steps S200 to S500, until the magnets 503 of all the magnet installation slots 502 on the rotor 5 are assembled. Specifically, first remove the positioning rod 4, and rotate the positioning plate 4 to drive the rotor 5 to rotate to the next assembly position, in which the four magnet installation slots 502 corresponding to the push magnet tooling 24 are not assembled with magnets 503.

[0075] Before step S100, it also includes: tooling assembly: first assembling the assembly platform 1, the assembly component 2, and the linear drive device together, and then driving the assembly component 2 to move left and right on the assembly platform 1 through the linear drive device to detect whether the assembly component 2 can run normally and smoothly.

[0076] Before step S500, the process further includes: tightening the sides of the plurality of magnets 503 by means of the magnet positioning tool 6, and waiting for the plurality of magnets 503 to be bonded and fixed to the rotor 5. Specifically, the second screw rod 602 is rotated, and the second screw rod 602 pushes the nylon block 603 to move along the magnet installation slot 502, thereby tightening the magnet 503 in the axial direction.

[0077] Embodiment 2:

[0078] See also Figure 8 This embodiment provides another surface-mounted rotor magnet assembly device. The difference from the first embodiment is that the number of the magnet pushing fixtures 24 in this embodiment is four, and the four magnet pushing fixtures 24 are respectively installed on the bottom plate 21, the cross beam 23 and the two side beams 22, so that when the bottom plate 21, the cross beam 23 and the two side beams 22 move in the axial direction, the magnet 503 can be pushed by the magnet pushing fixtures 24. Of course, the number of the magnet pushing fixtures 24 in this embodiment can also be two, which are respectively installed on the bottom plate 21 and the cross beam 23, or on the two side beams 22.

[0079] In addition, the linear drive device of this embodiment uses a cylinder to replace the ball screw drive assembly in Embodiment 1. The cylinder is arranged in the left-right direction, and the end of the piston rod of the cylinder is connected to the bottom of the assembly 2, and the cylinder can drive the assembly 2 to move in the left-right direction.

[0080] It should be noted that the surface-mounted rotor magnet assembly equipment of this embodiment can be installed on a work surface to perform the assembly of the rotor surface-mounted magnets.
