Description

Technical Field

[0001] This application relates to the field of motor rotor assembly equipment technology, and in particular to a multi-station rotor permanent magnet tensioning spring installation device. Background Technology

[0002] In some rotor structures, U-shaped retaining rings are used as tensioning elements to effectively secure permanent magnets. These U-shaped retaining rings improve rotor stability. For example, patent application CN104321951A discloses a motor rotor that uses U-shaped retaining rings as tensioning elements to secure permanent magnets. Therefore, in the preliminary step of installing the permanent magnets onto the rotor, the U-shaped retaining ring needs to be installed in the retaining ring mounting position on the rotor.

[0003] Refer to the instruction manual appendix Figure 2 The U-shaped retainer is not a regular U-shaped structure and has directionality. However, when the U-shaped retainer is fed, a vibratory feeder is used for feeding. Because the retainer is small, the direction of the retainer after being fed by the vibratory feeder is not consistent. The attitude adjustment mechanism can only adjust the retainer from horizontal to vertical, but cannot change the direction of the retainer.

[0004] Since the rotor permanent magnets are arranged in a circular pattern, several tensioning springs are also arranged in a circular pattern. The orientation of the springs used to tension the permanent magnets on each rotor is different, so the position and orientation of each spring need to be adjusted before installation.

[0005] However, if a clamping device is used to clamp the snap ring and adjust its position, the snap ring installation efficiency will be low.

[0006] It should be noted that the above background information is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content

[0007] The technical problem to be solved by this application is that since the rotor permanent magnet is arranged in a circular pattern, and a number of tensioning snap rings are also arranged in a circular pattern, the setting direction of the snap rings used to tension the permanent magnets on each rotor is different. Therefore, the position and direction of each snap ring need to be adjusted before installation. However, if a clamping device is used to clamp the snap rings and adjust their positions, the installation efficiency of the snap rings will be low.

[0008] To address the aforementioned technical problems, this application provides a rotor permanent magnet tensioning snap ring mounting device, used to transport the snap ring from the feeding device to the direction adjustment device, and then clamp and install it onto the snap ring mounting position between the permanent magnets of the rotor. The snap ring mounting device is characterized by comprising at least: a transport clamping unit for transporting the snap ring from the feeding device to the direction adjustment device; and an installation clamping unit for clamping and installing the snap ring, after adjustment by the direction adjustment device, onto the snap ring mounting position.

[0009] The rotor permanent magnet tensioning snap ring installation device provided in this application transports the snap ring from the feeding device to the direction adjustment device, and then installs it into the snap ring mounting position between the rotor permanent magnets after adjustment, thus achieving efficient installation of the snap ring.

[0010] In order to enable the movement of the transport clamping unit and the installation clamping unit, as an option of the aforementioned rotor permanent magnet tensioning spring mounting device, the transport clamping unit and the installation clamping unit are arranged on the moving unit, so that the transport clamping unit and the installation clamping unit can at least move horizontally and / or vertically.

[0011] Optionally, horizontal movement is driven by a first drive mechanism, and vertical movement is driven by a second drive mechanism.

[0012] In order to achieve simultaneous transport and installation of multiple snap rings, as an improvement to the above-mentioned rotor permanent magnet tension snap ring installation device, the rotor permanent magnet tension snap ring installation device includes a plurality of transport clamping units capable of clamping a plurality of snap rings, and the transport clamping unit includes transport clamping components.

[0013] To facilitate the clamping and releasing of the snap ring, as an improvement to the aforementioned rotor permanent magnet tension snap ring mounting device, the transport clamping components include a first transport clamp and a second transport clamp positioned opposite each other. The first transport clamp and the second transport clamp are driven by a third drive mechanism to adjust their mutual distance to clamp or release the snap ring.

[0014] In order to enable the simultaneous installation of multiple retaining rings, as an improvement to the above-mentioned rotor permanent magnet tensioning retaining ring installation device, the rotor permanent magnet tensioning retaining ring installation device includes a plurality of installation clamping units capable of clamping a plurality of retaining rings, and the installation clamping unit includes installation clamping components.

[0015] To facilitate the clamping and installation of the snap ring, as an improvement to the aforementioned rotor permanent magnet tension snap ring installation device, the installation clamping components include: a first installation clamp and a second installation clamp arranged in opposite positions, and the snap ring is clamped or released by adjusting the mutual distance between the first installation clamp and the second installation clamp.

[0016] Preferably, the first mounting clamp and the second mounting clamp are mounted on the fourth drive mechanism.

[0017] In order to press the snap ring released in the snap ring mounting position so that the snap ring can be firmly installed on the rotor, as an improvement of the above-mentioned rotor permanent magnet tension snap ring mounting device, the mounting clamping member further includes: a pressing member, located between the first mounting clamping member and the second mounting clamping member, and the pressing member can be moved in the vertical direction by the fifth driving mechanism, for pressing down the snap ring released in the snap ring mounting position.

[0018] In order to enable the installation of retaining rings on rotors of different specifications, as an improvement to the rotor permanent magnet tension retaining ring installation device, the rotor permanent magnet tension retaining ring installation device is provided with two installation clamping units, which are installed on the horizontal distance adjustment component.

[0019] The technical advantages of this application are as follows: The rotor permanent magnet tensioning snap ring installation device provided in this application transports the snap ring from the feeding device to the direction adjustment device, and then installs it into the snap ring mounting position between the rotor permanent magnets after adjustment, thus achieving efficient installation of the snap ring.

[0020] By providing a pressing element on the mounting clamp, the retaining ring released in the retaining ring mounting position can be pressed, so that the retaining ring can be firmly installed on the rotor. Attached Figure Description

[0023] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0024] like Figure 1 The diagram illustrates a rotor 5000, employing U-shaped retaining rings 2000 as tensioning elements to fix permanent magnets. The permanent magnets of the rotor 5000 are arranged in a circular array, and correspondingly, several tensioning retaining rings 2000 for tensioning the permanent magnets are also arranged in a circular array. (Refer to...) Figure 2 The U-shaped retaining ring is not a regular U-shape; it has a directionality. Since each retaining ring 2000 used to tension the permanent magnet has a different orientation, the position and orientation of each retaining ring 2000 need to be adjusted before installation. However, if a single clamping device is used to simultaneously clamp the retaining ring and adjust its position and orientation, the installation efficiency will be low, which cannot meet the needs of large-scale production.

[0025] Reference Figure 3 This illustration shows the rotor permanent magnet tensioning snap ring mounting device provided in this application, which aims to efficiently transport the snap ring 2000 from the feeding device 3000 to the direction adjusting device 4000, and then, after adjustment, install it into the snap ring mounting position 5001 between the permanent magnets of the rotor 5000. The device includes a transport clamping unit 1 and an installation clamping unit 2, enabling efficient installation of the snap ring.

[0026] Reference Figure 3The transport clamping unit 1 is responsible for conveying the retaining ring 2000 from the feeding device 3000 to the direction adjusting device 4000. The transport clamping unit 1 may include clamping components and a drive mechanism. During operation, the feeding device 3000 moves the retaining rings 2000 one by one or in groups to designated positions. The drive mechanism of the transport clamping unit 1 is activated, driving the clamping component of the transport clamping unit 1 to the position of the retaining ring 2000. At this time, the clamping component opens under the control of the drive mechanism, clamps the retaining ring 2000, and then closes. After clamping the retaining ring 2000, the drive mechanism operates again, transporting the retaining ring 2000 to the designated position of the direction adjusting device 4000 according to a preset trajectory. During the transport process, the position and status of the retaining ring can be monitored by sensors. After reaching the designated position, the clamping component releases the retaining ring 2000 and places it on the direction adjusting device 4000, completing the transport task of the retaining ring.

[0027] Reference Figure 3 The orientation adjustment device 4000 is used to adjust the position and orientation of the transported snap ring 2000 to meet the requirements of the snap ring mounting position 5001 on the rotor 5000. Optionally, this device may include a rotating platform, a positioning sensor, and an adjustment mechanism (not shown in the figure). After the snap ring 2000 is placed on the rotating platform, the positioning sensor detects the current orientation of the snap ring and compares it with the preset correct orientation. Based on the comparison result, the adjustment mechanism drives the rotating platform to rotate, causing the snap ring 2000 to rotate to the correct orientation. Once the snap ring orientation is adjusted to meet the requirements, the mounting clamping unit 2 performs the clamping and mounting operations.

[0028] The mounting clamping unit 2 is used to clamp and install the snap ring 2000, after adjustment by the direction adjustment device 4000, into the snap ring mounting position 5001 between the permanent magnets of the rotor 5000. Its structure also includes clamping components and a drive mechanism. After the adjustment device 4000 adjusts the snap ring position, the drive mechanism of the mounting clamping unit 2 is activated, moving it to the position of the snap ring 2000 on the direction adjustment device 4000. At this time, the clamping component accurately opens and clamps the snap ring 2000, which has been oriented correctly. After clamping the snap ring 2000, the drive mechanism operates again, transporting the snap ring 2000 along a preset trajectory to above the snap ring mounting position 5001 on the rotor 5000. When the snap ring 2000 is aligned with the mounting position 5001, the clamping component slowly releases the snap ring 2000 under the control of the drive mechanism, allowing the snap ring 2000 to accurately fall into the snap ring mounting position 5001. After installation, the clamping unit 2 returns to its initial position, ready for the next installation task.

[0029] Through the coordinated operation of the transport clamping unit 1 and the installation clamping unit 2, the rotor permanent magnet tensioning snap ring installation device of this application achieves efficient installation of the snap ring.

[0030] Continue to refer to Figures 3-4 In some preferred embodiments, the transport clamping unit 1 and the mounting clamping unit 2 are jointly disposed on the moving unit 3, so that the transport clamping unit 1 and the mounting clamping unit 2 can at least move horizontally and / or vertically synchronously.

[0031] The moving unit 3 enables the movement of the transport clamping unit 1 and the mounting clamping unit 2, and its structure can include various forms. (Refer to...) Figure 3 A common structure is a track-type moving structure, which mainly includes a horizontal track 312, a vertical track 322, a slider, and a drive mechanism.

[0032] The horizontal track 312 is fixed to the frame of the device, while the vertical track 322 is mounted on the slider of the horizontal track. The vertical track 322 moves along with the slider on the horizontal track 312 and can also move vertically. The slider cooperates with both the horizontal track 312 and the vertical track 322, achieving smooth movement through rolling or sliding. The drive mechanism provides power for the slider's movement. Power can be transmitted to the slider via gear transmission, chain transmission, or screw transmission through pneumatic, electric, or hydraulic drives, thereby controlling the slider's movement. When horizontal movement is required, taking the track-type moving structure as an example, the drive mechanism is activated, driving the slider on the horizontal track 312 to move through the transmission device. The slider then moves the vertical track 322, along with the transport clamping unit 1 and the mounting clamping unit 2 mounted on the vertical track, together in the horizontal direction. When vertical movement is required, the drive mechanism of the vertical track mounted on the slider of the horizontal track is activated, causing the slider on the vertical track 322 to move up and down. The slider then drives the transport clamping unit 1 and the mounting clamping unit 2 to move vertically. For example, when the mounting clamping unit 2 needs to install the snap ring 2000 to the rotor snap ring mounting position 5001 at different heights, the vertical movement function can make it reach the appropriate height and complete the snap ring installation operation.

[0033] Another feasible structure is a robotic arm-type movement structure (not shown in the figure), with a multi-joint robotic arm as the core. Each joint of the robotic arm is driven by servo motors, enabling complex spatial movements. The transport clamping unit 1 and the mounting clamping unit 2 are mounted on the end effector of the robotic arm. Through rotation, extension, and swinging movements of the robotic arm, horizontal and vertical movement, as well as adjustments at various angles, are achieved. In the robotic arm-type movement structure, servo motors drive the corresponding joints of the robotic arm to rotate, causing the end effector to move horizontally, thereby driving the transport clamping unit 1 and the mounting clamping unit 2 to move horizontally. In the robotic arm-type movement structure, servo motors drive the relevant joint movements of the robotic arm, causing the end effector to rise or fall vertically, thereby driving the transport clamping unit 1 and the mounting clamping unit 2 to move vertically. By precisely controlling the movement of each joint of the robotic arm, the mounting clamping unit 2 can be precisely positioned vertically to meet the requirements of different height clasp mounting positions.

[0034] By arranging the transport clamping unit 1 and the mounting clamping unit 2 on the moving unit 3, at least horizontal and / or vertical movement is achieved.

[0035] Continue to refer to Figure 3 Horizontal movement is driven by the first drive mechanism 31, and vertical movement is driven by the second drive mechanism 32. The first drive mechanism 31, which provides power to the first drive unit 311, can adopt various common drive forms used in the drive mechanisms described above. Figure 3 The diagram illustrates the first driving device 311 as a cylinder. When it is necessary to drive the transport clamping unit 1 and the mounting clamping unit 2 to move horizontally, the control system sends a signal to the solenoid valve of the cylinder. After receiving the signal, the solenoid valve changes the air intake state at both ends of the cylinder, causing the cylinder piston to move to the right under the action of air pressure. This causes the transport clamping unit 1 and the mounting clamping unit 2, which are connected to the cylinder's power output shaft, to move to the right together. Optionally, a limit device and a sensor are provided at the end of the guide device to stop the movement of the moving unit 3 after it has moved to a specific position.

[0036] The second drive mechanism 32 can also adopt various structural forms, see reference. Figure 3 The second drive unit 321, used to provide power, can adopt various common drive forms used in the drive mechanism described above. Figure 3 The second drive device 321 is shown as a cylinder, and its principle will not be described in detail here.

[0037] Continue to refer to Figure 3 , Figure 7 The transport clamping unit 1 includes a plurality of transport clamping members 11 capable of clamping a plurality of retaining rings 2000, as shown in the reference. Figure 5The transport clamping member 11 includes a first transport clamp 111 and a second transport clamp 112 positioned opposite each other. The opposing surfaces of the first transport clamp 111 and the second transport clamp 112 are configured as clamping grooves or clamping surfaces that match the shape of the snap ring 2000.

[0038] Reference Figure 5 The third drive mechanism 12 is used to drive the first transport clamp 111 and the second transport clamp 112 to adjust their relative distance, thereby achieving the action of clamping or releasing the snap ring 2000. This drive mechanism can take various forms. Taking a cylinder-driven structure as an example, the cylinder acts as a power source, using compressed air to achieve the reciprocating motion of the piston. The piston rod is connected to the piston, transmitting the piston's motion to the first transport clamp 111 or the second transport clamp 112. When the snap ring 2000 needs to be clamped, the control system sends a command to the cylinder, causing compressed air to enter one end of the cylinder, pushing the piston and piston rod outwards. The piston rod, through a connecting piece, drives the first transport clamp 111 or the second transport clamp 112 to move closer to the other clamp, thereby reducing the distance between the two clamps and clamping the snap ring 2000 between the clamping groove or clamping surface. When it is necessary to release the retaining ring 2000, the control system controls the cylinder to allow compressed air to enter the other end of the cylinder, pushing the piston and piston rod inward to contract. This causes the clamping member to move away from the other clamping member, increasing the distance between the two clamping members, thereby releasing the retaining ring 2000. (Refer to...) Figure 3 , Figure 7 The transport clamping unit 1 is configured in several ways. For example, two transport clamping units 1 are arranged in a straight line. The configuration of the transport clamping unit 1 improves the installation efficiency.

[0039] Similar in structure to transport clamp 11, continue to refer to Figure 6 , Figure 7 The mounting clamping unit 2 is configured with several units, and each mounting clamping unit 2 includes a mounting clamping member 21. (Refer to...) Figure 6 The mounting clamp 21 includes a first mounting clamp 211 and a second mounting clamp 212 positioned opposite each other. The fourth drive mechanism 22, which drives the first mounting clamp 211 and the second mounting clamp 212 to adjust their relative distance, can take various forms, such as electric drive or cylinder drive. Its principle is similar to that of electric grippers or pneumatic grippers currently sold on the market, and is also similar to the principle of the aforementioned transport clamp 11, so it will not be described in detail here.

[0040] The mounting clamping unit 2 is provided with several mounting clamping parts 21. For example, the layout is set according to the setting of the rotor snap ring mounting position 5001. For example, it is set as two mounting clamping parts 21 with opposite positions, which are used to install two snap rings at the snap ring mounting position 5001 at the same time, which can improve the installation efficiency.

[0041] Continue to refer to Figure 1 The second clamping member 21 further includes a pressing member 213, located between the first mounting clamping member 211 and the second mounting clamping member 212, and the pressing member 213 is movable in the vertical direction by the fifth driving mechanism 24, for pressing down the snap ring 2000 released in the snap ring mounting position 5001.

[0042] After the snap ring is transported to the snap ring mounting position 5001 and released, the pressing member 213 can move vertically to accurately press the snap ring down to the specified position, ensuring that the snap ring and the rotor are tightly fitted, improving the accuracy and stability of the installation, and thus improving the installation quality and production efficiency of the entire device.

[0043] The fifth drive mechanism 24 can use various types of drive devices to realize the vertical movement of the pressing member 213, such as electric cylinder drive or pneumatic cylinder drive, to drive the vertical movement of the pressing member 213.

[0044] Reference Figure 7 , Figure 8 To accommodate the simultaneous installation of two different retaining rings 2000 at retaining ring mounting positions 5001 on rotors 5000 of different specifications, in one embodiment, the rotor permanent magnet tensioning retaining ring mounting device is provided with two mounting clamping units 2, which are mounted on a horizontal distance adjustment assembly 23. Exemplarily, a spacing adjustment slider 233 is provided at the upper end of each mounting clamping unit 2, and a spacing adjustment guide rail 232 is installed at the bottom of the mounting plate of the mounting clamping unit 2. This allows the spacing between the two mounting clamping units 2 with the spacing adjustment sliders 233 to be adjusted by moving the sliders 233. To limit the spacing between the mounting clamping units 2, a limiting protrusion 2311 on the spacing limiting block 231 engages with a groove on the two spacing adjustment sliders 233, thereby limiting the spacing between the mounting clamping units 2. When it is necessary to adjust the spacing between the mounting clamping units 2, this can be achieved by replacing different spacing limiting blocks 231. Since the rotor specifications all conform to relevant standards, as long as different limiting protrusions 2311 and different spacing limiting blocks 231 are equipped, two snap rings can be installed on the snap ring mounting position 5001 on rotors of different specifications at the same time.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
