Description

Technical Field

[0001] The utility model relates to the technical field of motor manufacturing, in particular to a rotor magnetizer. Background Art

[0002] In the process of motor production, the magnetization of the rotor is one of the key links. The motor rotor magnetizer places the rotor in a magnetizing coil through an energized magnetizing part or magnetizing coil, and applies a DC high-voltage to the magnetizing coil. The current pulse generates a strong magnetic field in the coil, and this magnetic field permanently magnetizes the rotor placed in the coil, thus realizing the magnetization of the rotor. The traditional motor rotor magnetizer can only magnetize rotors with fixed sizes. When the size of the rotor changes, a new motor rotor magnetizer is required for magnetization, resulting in a relatively high magnetization cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0018] Please refer to Figures 1 - 3 , Figure 1 which is a schematic diagram of the overall structure of the rotor magnetizing machine of the present utility model,Figure 2 It is a schematic structural view of the ejecting member 106 of the present utility model. Figure 3 It is a schematic structural view of the material guiding groove 109 and the receiving table 110 of the present utility model.

[0019] The rotor magnetizing machine of the present utility model includes a workbench 101, a controller 102, a magnetizing head 103, a mounting seat 104, a first air cylinder 105, an ejecting member 106, a transfer table 107, a second air cylinder 108, a material guiding groove 109, a receiving table 110, a lifting air cylinder 111, a top plate 112, a magnetic sensor 113, a first contact plate 114, a second contact plate 115, and a limiting bar 116, which solves the problem that after the magnetizing process is completed, discharging is required, but the prior art does not have an automatic discharging mechanism and can only discharge manually by workers, resulting in a low degree of automation. It can be understood that the foregoing solution can also be used to ensure the consistency of products.

[0020] In this embodiment, the workbench 101 mainly plays a role of stable support. The controller 102 is a programmable logic controller, which can achieve coordinated cooperation of multiple-step operations through programming to meet the requirements of different production tasks. The magnetizing head 103 is a prior art and is used to magnetize the rotor. It is installed on the workbench 101 through the discharging assembly, thereby realizing automatic discharging, which solves the problem that after the magnetizing process is completed, discharging is required, but the prior art does not have an automatic discharging mechanism and can only discharge manually by workers, resulting in a low degree of automation.

[0021] Among them, the mounting base 104 is fixedly connected to the workbench 101 and is located on one side of the workbench 101 close to the magnetizing head 103. The first cylinder 105 is installed on the mounting base 104 and is located on the side of the mounting base 104 away from the workbench 101. The ejecting member 106 is installed on the workbench 101. The transfer table 107 is fixedly connected to the workbench 101 and is located on one side of the workbench 101 close to the magnetizing head 103. The second cylinder 108 is installed on the transfer table 107. The material guiding groove 109 is fixedly connected to the transfer table 107 and is located on one side of the transfer table 107. The receiving table 110 is fixedly connected to the workbench 101 and is located on one side of the workbench 101. The mounting base 104 is fixedly installed on the top of the workbench 101 to support the first cylinder 105, provide installation conditions for the first cylinder 105, and ensure that the first cylinder 105 can be installed at the specified position height. The first cylinder 105 is horizontally installed on the mounting base 104 through bolts, and the output end direction faces the direction of the magnetizing head 103. The ejecting member 106 is installed at the magnetizing head 103 and is used to eject the rotor upward. The transfer table 107 is installed on the top of the workbench 101 and is located on the opposite side of the first cylinder 105. The second cylinder 108 is fixedly installed on the top of the transfer table 107 through bolts and is used to push the magnetized rotor. The material guiding groove 109 is located on the side of the transfer table 107 and is in a slope shape, and is used to guide the rotor. The receiving table 110 is located below the material guiding groove 109 and is used to receive the magnetized rotor. Through the coordinated cooperation of the ejecting member 106, the first cylinder 105 and the second cylinder 108, the automatic discharging of the rotor is realized, and the problem that after the magnetizing process is completed, discharging is required, but the existing technology does not have an automatic discharging mechanism and can only be manually discharged, resulting in a low degree of automation, is solved.

[0022] Secondly, the lifting cylinder 111 is installed on the workbench 101 and is located on one side of the workbench 101 close to the magnetizing head 103; the top plate 112 is sleeved outside the magnetizing head 103 and is fixedly connected to the output end of the lifting cylinder 111. The number of the lifting cylinders 111 is two, which are respectively vertically installed on both sides of the magnetizing head 103. The top plate 112 is a rectangular plate, and a through hole matching the size of the magnetizing head 103 is opened in the middle. The top plate 112 is sleeved outside the magnetizing head 103 through the through hole. By the extension of the lifting cylinder 111, the top plate 112 is driven to eject the rotor.

[0023] Meanwhile, the magnetic sensor 113 is installed on the adapter table 107 and is located on the side of the adapter table 107 close to the second cylinder 108. The magnetic sensor 113 can be bolted to the adapter table 107 and is used to detect whether the rotor is magnetized. The magnetic sensor is electrically connected to the controller 102 to provide a feedback signal to the controller 102. Through the magnetic sensor 113, the detection of the magnetization condition of the rotor can be realized, ensuring that there is no magnetic leakage in the rotor and guaranteeing the product consistency.

[0024] In addition, the first contact plate 114 is fixedly connected to the output end of the first cylinder 105; the second contact plate 115 is fixedly connected to the output end of the second cylinder 108. The first contact plate 114 and the second contact plate 115 are respectively installed on the first cylinder 105 and the second cylinder 108. When the first cylinder 105 and the second cylinder 108 extend, the first contact plate 114 and the second contact plate 115 come into contact with the rotor to push the rotor. Through the first contact plate 114 and the second contact plate 115, the rotor can be better pushed.

[0025] Finally, the limit bar 116 is fixedly connected to the adapter table 107 and is located on the side of the adapter table 107 close to the first cylinder 105. The limit bar 116 is fixedly installed on the top of the adapter table 107 and can block the rotor to prevent the rotor from being overly displaced when pushed by the first cylinder 105. Through the limit bar 116, the limitation of the rotor can be realized.

[0026] In this embodiment, the controller 102 is pre-set with a magnetization program. During magnetization, the rotor is installed on the magnetization head 103, and the controller 102 is started. The controller 102 activates the magnetization head 103 to magnetize the rotor. After the magnetization of the rotor is completed, the controller 102 controls the lifting cylinder 111 to extend, driving the top plate 112 to move upward and be flush with the transfer table 107. During the upward movement of the top plate 112, the rotor is ejected from the magnetization head 103, causing the rotor to fall onto the top plate 112. Then, the first cylinder 105 extends, and the rotor is pushed onto the transfer table 107 through the first contact plate 114, in front of the second cylinder 108. The limit stop bar 116 positions the rotor to prevent excessive displacement of the rotor. At this time, the magnetic sensor 113 detects whether the rotor is magnetized. If not magnetized, the entire device stops operating and waits for the operator to handle it. If magnetized, the controller 102 activates the second cylinder 108. The second cylinder 108 extends, and the rotor is pushed into the material guide groove 109 through the second contact plate 115. Under the action of gravity, the rotor slides onto the receiving table 110, completing automatic discharging. Through the coordinated cooperation of the lifting cylinder 111, the first cylinder 105, and the second cylinder 108, this application realizes the automatic discharging of the rotor. At the same time, in combination with the detection of the rotor by the magnetic sensor 113, it can also ensure that there are no rotor with magnetic leakage, guarantee product consistency, and solve the problem that since discharging is required after the magnetization process, the prior art does not have an automatic discharging mechanism and can only discharge manually, resulting in a low degree of automation.

[0027] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
