Description

Technical Field

[0001] The invention relates to the technical field of magnetization, and in particular to a single-station magnetization detection device for rotor magnetization. Background Art

[0002] During the manufacturing process of the motor rotor, it is necessary to magnetize the rotor to make it magnetic. Fig.13 The rotor shown has a main body section 101 and end portions 102 formed at both ends of the main body section 101. The end portions 102 are used for assembly, and their diameter is smaller than the diameter of the main body section 101. A slot 103 is formed on the end portions for connecting the rotor to other components when installing the rotor or for locking the rotor in position when magnetizing. When the rotor is magnetized, the rotor is placed in a magnetizing device as a whole, and the magnetization amount is detected after magnetization. The existing magnetization detection process for the rotor is generally divided into two stations. The magnetization is performed at the magnetization station and then flows into the detection station to detect the magnetization amount. The common layout method is to use an assembly line or a turntable. The overall structure occupies more space, and corresponding positioning components are required at the corresponding stations, resulting in more functional components required as a whole. Summary of the invention

[0003] In view of the above, it is necessary for the present invention to provide a single-station magnetization and detection device which has a simplified structure, saves space, and can integrate rotor magnetization and detection.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A single-station magnetization detection device for rotor magnetization comprises a machine platform, a frame, a magnetization box, a lifting and clamping mechanism and a detection mechanism. The frame is erected on the machine platform, the magnetization box is installed on the machine platform, and the magnetization box has a magnetization channel penetrating up and down. The lifting and clamping mechanism comprises an upper clamping mechanism and a lower clamping mechanism. The upper clamping mechanism is installed on the frame and comprises a lower abutment shaft that can be lifted and rotated and corresponds to the top of the magnetization channel. The lower clamping mechanism is installed below the surface of the machine platform and comprises an upper abutment shaft that can be lifted and rotated and corresponds to the bottom of the magnetization channel. The rotor is clamped at the upper and lower ends by the lower abutment shaft and the upper abutment shaft, and the rotor is moved into the magnetization channel to a preset height position for magnetization. The detection mechanism is installed on the machine platform and located on one side of the magnetization box, and comprises a laterally movable detection head, which is used to detect the magnetization magnetic flux of the rotor through the detection head when the rotor rises to a preset position after being magnetized in the magnetization box.

[0006] The beneficial effects of the present invention are:

[0007] The single-station magnetization detection device for rotor magnetization provided by the present invention clamps the rotor and can be limited to a corresponding height position by the lifting and clamping mechanism, so that the rotor can be magnetized at the height corresponding to the magnetization position. After the magnetization is completed, the rotor is lifted to the corresponding detection mechanism, and the magnetization amount is detected by the detection mechanism. The magnetization and detection can be integrated at one station, which greatly simplifies the structure of the device, saves layout space, and greatly simplifies the structure of the device.

It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

It includes a transversely movable detection head 82, which is used to detect the magnetizing magnetic flux of the rotor through the detection head 82 when the rotor leaves the magnetizing box 30 and rises to a preset position after being magnetized in the magnetizing box 30.

[0025] The machine 10 includes a table panel 11 , on which a slideway 12 is provided, so that the magnetizing box 30 can slide along the slideway 12 and slide to the bottom corresponding to the frame 20 when being installed, and then be locked and fixed by a locking piece.

[0026] The frame 20 includes a guide column 21 and a top plate 22. The guide column 21 is fixedly erected on the table panel 11, and the top plate 22 is fixedly installed on the top of the guide column 21. In this example, there are four guide columns 21 supported at the four corners of the top plate 22.

[0027] See also Figure 4 The upper clamping mechanism includes a lifting plate 41, a lower shaft 42, a lower shaft fixing seat 43, and a driving mechanism 44. The lifting plate 41 can be raised and lowered on the guide column 21. The lower shaft 42 is installed on the bottom surface of the lifting plate 41 through the lower shaft fixing seat 43. The lower shaft 42 is lifted and lowered together with the lifting plate 41. The upper end of the lower shaft 42 extends to the top surface of the lifting plate 41, and the lower end of the lower shaft 42 is used to abut against the top of the rotor. The driving mechanism 44 is installed on the top surface of the lifting plate 41, and is used to connect the upper end of the lower shaft 42 to drive the lower shaft 42 to rotate.

[0028] It can be understood that the upper clamping mechanism further includes a servo screw, which is mounted on the top plate 22 of the frame 20 to drive the lifting plate 41 to move up and down.

[0029] See also Figure 5-Figure 8 The lower shaft fixing seat 43 includes a seat body 431 and a bearing seat 432. The seat body 431 is fixedly connected to the bottom surface of the lifting plate 41. The center of the seat body 431 is provided with an axial through hole 4311. The bearing seat 432 is fixedly installed in the axial through hole 4311 of the seat body 431. The center of the bearing seat 432 is provided with a lower shaft 42. The lower shaft 42 passes through the lifting plate 41 and is in driving connection with the driving mechanism 44 on the top surface of the lifting plate 41, so that the lower shaft 42 can rotate relative to the lower shaft fixing seat 43. Preferably, the driving mechanism 44 adopts a structure of a motor and a conveyor belt.

[0030] Furthermore, the bearing seat 432 includes a base and a bearing installed on the base, and a through hole is formed on the base and is correspondingly connected to the center hole of the bearing for the lower shaft 42 to pass through; a connecting hole is opened on the outer peripheral surface of the base, and the bearing seat 432 is installed in the seat body 431 and connected to the seat body 431 through the connecting hole.

[0031] Furthermore, the lower support shaft 42 includes a shaft body and a clamping structure installed in the shaft body. The upper end of the shaft body is transmission-connected to the driving mechanism 44 and is driven to rotate by the driving mechanism 44. The clamping structure is used to clamp the shaft body to the rotor, thereby driving the rotor to rotate together.

[0032] Furthermore, the shaft body includes a lower shaft body 421 and an upper shaft body 422 axially connected to the lower shaft body 421. A bearing hole 4211 is axially opened on the top surface of the lower shaft body 421. The bearing hole 4211 is opened with a preset depth. A top hole 4212 is axially opened downward on the bottom surface of the bearing hole 4211, which passes through the bottom surface of the lower shaft body 421.

[0033] The clamping structure includes a pressing component and a clamping component. The pressing component is used to clamp the top of the rotor by the pressing component before the lower shaft 42 is clamped with the rotor (that is, the shaft body needs to rotate relative to the rotor before clamping, so that when the caliper component on the shaft body is rotated to align with the clamping slot of the rotor, the clamping component is clamped into the clamping slot of the rotor), so as to keep the rotor stationary while the shaft body can rotate relative to the rotor, and to allow a gap between the bottom end surface of the lower shaft body 421 and the top surface of the rotor to prevent the bottom end surface of the lower shaft 42 from contacting the top surface of the rotor, causing rotation interference or driving the rotor to move in conjunction. It is used to align the clamping component with the clamping slot of the rotor.

[0034] The pressing assembly includes a pressing column 51, a pressing cover 52, a plurality of bearings 53 and a retaining spring 54; the lower end of the pressing column 51 is a top cone, which is used to press against the center of the top surface of the rotor, and the upper end of the pressing column 51 is formed into a stage for sleeve-mounting a plurality of bearings 53; the pressing cover 52 is used to press on the top ends of the plurality of bearings 53 to limit the plurality of bearings 53 in axial direction; the retaining spring 54 is clamped on the top end of the pressing column 51 to prevent the pressing column 51 from falling off relative to the bearing 53.

[0035] Specifically, a plurality of bearings 53 are tightly sleeved on the stage of the push-pull column 51 and accommodated in the bearing hole 4211 of the lower shaft body 421. The plurality of bearings 53 are supported by the bottom surface of the bearing hole 4211 (specifically, the outer ring of the supporting bearing 53). The radial dimension of the bearing 53 is equivalent to the radial dimension of the bearing hole 4211. The lower end of the push-pull column 51 extends into the top hole 4212 to a preset depth and does not extend to the bottom end of the lower shaft body 421. A locking groove 4213 surrounding the bearing hole 4211 is provided on the top surface of the lower shaft body 421. The pressure cover 52 is locked in the locking groove 4213 by a pin, and the pressure cover 52 is pressed against the outer ring of the bearing 53. In this way, the plurality of bearings 53 are limited between the bottom surface of the bearing hole 4211 and the pressure cover 52 to prevent axial movement. When the lower shaft 421 rotates, the pressure cover 52 and the outer ring of the bearing 53 rotate together with the lower shaft 421, and the abutting column 51 is supported on the top surface of the rotor and will not rotate together.

[0036] Furthermore, a receiving groove 521 is provided on the top surface of the pressure cover 52, and a through hole is provided in the center of the receiving groove 521 so that the upper end of the supporting column 51 can be inserted upward into the receiving groove 521. The retaining spring 54 is installed in the receiving groove 521 and is clamped on the top end of the supporting column 51 to prevent the supporting column 51 from falling off relative to the bearing 53 in the axial direction.

[0037] The clamping assembly is used to clamp with the rotor so that the shaft body drives the rotor to rotate together when it rotates. The clamping assembly includes a clamping rod 55, a cross block 56 and a spring 57. There are two clamping rods 55, which can be axially slidably installed in the shaft body. The two clamping rods 55 are vertically connected to the two ends of the cross block 56. The cross block 56 is against the top surface of the pressure cover 52. The spring 57 is used to press downward against the top surface of the cross block 56 to provide elastic force for the cross block 56 to move downward.

[0038] Specifically, a guide slide hole 4214 is provided on the top surface of the lower shaft body 421 in the axial direction and penetrates the entire lower shaft body 421. There are two guide slide holes 4214, which are arranged opposite to each other in the radial direction of the lower shaft body 421. Two clamping rods 55 are respectively slidably arranged in the guide slide holes 4214, and the lower ends of the clamping rods 55 extend to the lower end of the lower shaft body 421. The cross-connecting block 56 spans and abuts against the gland 52. One end of the spring 57 abuts against the cross-connecting block 56, and the other end abuts against the upper shaft body 422 (after the lower shaft body 421 and the upper shaft body 422 are fixedly connected), providing a downward elastic force to the cross-connecting block 56. When the lower shaft body 421 is pressed against the rotor, the clamping rod 55 will be pushed upward by the rotor, and the clamping rod 55 together with the cross-connecting block 56 will move upward, and the spring 57 will be compressed until the top of the rotor hits the top cone of the top column 51; at this time, the rotor is fixed by the top column 51, and then the shaft body rotates, driving the clamping rod 55 to rotate relative to the top surface of the rotor, and the top column 51 maintains the rotor and does not rotate. When the clamping rod 55 rotates to align with the slot on the rotor, the lower end of the clamping rod 55 will enter the slot, and then the clamping rod 55 will drive the rotor to rotate together. It can be understood that an encoder can be set at the top of the shaft body to record the position and rotation angle of the shaft body. Through the encoder recording, the lower shaft body 421 can be rotated back to the initial position first, and then rotated to the required angle, so as to achieve precise adjustment of the rotor to the required angle in the magnetizing box.

[0039] The clamping structure may further include a clamping position sensing structure for monitoring the clamping position state of the clamping rod 55; the clamping position sensing structure includes a column 61, a transverse pin 62, an induction ring 63 and a clamping sensor 64. The column 61 is fixedly connected to the transverse block 56 and rises and falls with the transverse block 56. The transverse pin 62 is laterally inserted into the column 61 and rises and falls together with the column 61. The two ends of the transverse pin 62 extend out of the outer periphery of the upper shaft body 422. The induction ring 63 is sleeved on the outer periphery of the upper shaft body 422 and connected to the two ends of the transverse pin 62. The transverse pin 62 rises and falls to drive the induction ring 63 to rise and fall; the clamping sensor 64 is installed on the outer periphery of the lower end of the seat body 431, and has two, arranged up and down. In this way, when the induction ring 63 rises to the preset height, the induction ring 63 senses the latching sensor 64 at the upper end, and it can be determined that the latching rod 55 is pushed up by the rotor; when the induction ring 63 falls back, the induction ring 63 senses the latching sensor 64 at the lower end, and it can be determined that the lower end of the latching rod 55 slides into the latching groove of the rotor.

[0040] Furthermore, an axial groove 4221 for sleeve the column 61 is axially opened on the bottom surface of the upper shaft body 422 to guide the column 61 to rise and fall, and a longitudinal groove 4222 is opened on the circumferential surface of the upper shaft body 422 to allow the cross pin 62 to extend and guide the cross pin 62 to rise and fall.

[0041] The clamping structure further includes a crimping sensing structure for detecting whether the lower shaft body 421 contacts the rotor when pressing against the rotor. The principle of the crimping sensing structure is roughly the same as that of the clamping sensing structure. The crimping sensing structure includes a crimping rod 65, an elastic guide sleeve 66, a sensing block 67 and a crimping sensor 68. The crimping rod 65 is slidably mounted on the lower shaft body 421 along the axial direction. The elastic guide sleeve 66 is sleeved on the crimping rod 65 to provide elastic force for the crimping rod 65 to reset downward. The sensing block 67 is arranged at the top of the crimping rod 65. The crimping sensor 68 is installed on the outer periphery of the lower end of the seat body 431. Specifically, the shaft body is provided with a crimping sensing channel for installing the crimping rod 65. A section of the crimping sensing channel in the upper shaft body 422 is set as a stepped hole structure, the lower end hole diameter is large, and the upper end hole diameter is small. The elastic guide sleeve 66 is installed in the lower end hole; the lower end of the crimping rod 65 is located at the lower end opening of the lower shaft body 421, and the upper end of the crimping rod 65 is located in the upper shaft body 422. Sensing holes are correspondingly opened on the peripheral wall of the upper shaft body 422 for sensing of the sensing block 67 and the crimping sensor 68. When the lower shaft body 421 is pressed against the rotor, the bottom end of the crimping rod 65 will contact the top surface of the rotor and move upward under the support of the rotor, so that the sensing block 67 at the top of the crimping rod 65 will move upward together, and the upward movement of the sensing block 67 will separate from the crimping sensor 68 corresponding to the lower end of the seat body 431, so that the crimping sensor 68 sends a signal that the lower shaft body 421 and the rotor are in contact; the elastic guide sleeve 66 is pressurized until the lower shaft body 421 is separated from the top of the rotor, and the crimping rod 65 returns to its original position under the elastic force of the elastic guide sleeve 66.

[0042] Furthermore, the upper clamping mechanism includes a rotation-stopping mechanism 45 for fixing the conveyor belt position of the driving mechanism 44 when the driving mechanism 44 is not activated.

[0043] See also Fig. 9 , Fig.10The lower clamping mechanism includes a fixing plate 71, a fixing column 72, a carrying plate 73, the upper abutment shaft 74 and a lifting cylinder 75. The fixing plate 71 is fixedly connected to the lower surface of the table panel 11 of the machine table 10, the fixing column 72 is fixedly connected to the lower surface of the fixing plate 71, the carrying plate 73 can be lifted and lowered on the fixing column 72, the upper abutment shaft 74 is fixedly established on the carrying plate 73, and the upper abutment shaft 74 passes through the fixing plate 71 and the table panel 11 upward to extend into the magnetizing channel of the magnetizing box 30, and the upper abutment shaft 74 is used to receive the bottom end of the rotor; the lifting cylinder 75 is fixedly erected on the table panel 11, and the piston of the lifting cylinder 75 passes through the table panel 11 and is connected to the carrying plate 73, so that the carrying plate 73 can be driven to rise and fall through the lifting cylinder 75, thereby driving the upper abutment shaft 74 to rise and fall.

[0044] See also Fig.11 The detection mechanism 80 includes a space moving frame 81 and a detection head 82. The space moving frame 81 is installed on the table panel 11 of the machine 10 and is located on one side of the magnetizing box 30. The space moving frame 81 includes a lifting slide and a horizontal slide installed on the lifting slide. The horizontal slide is connected to a mounting plate 811. The lifting slide cooperates with the horizontal slide to drive the mounting plate 811 to move in height and horizontal directions. The detection head 82 is installed on the mounting plate 811, so that the detection head 82 can be driven to approach the outer periphery of the rotor through the movement of the mounting plate 811. Through the rotation of the rotor, the detection head 82 can detect the magnetization amount of the magnetic steel on the outer periphery of the rotor. In addition, the detection head 82 can be driven to rise and fall by the mounting plate 811, so that different height positions of the rotor can be detected, thereby realizing a comprehensive detection of the outer peripheral surface of the rotor.

[0045] See also Fig.12 Furthermore, the single-station magnetization detection device includes a machine cover 90 and a control system. The cover is arranged on the machine platform 10, and the control system is installed in the machine platform 10 to control the actions of various mechanisms.

[0046] When the single-station magnetization detection device of the present invention magnetizes the rotor, the rotor is first placed on the upper abutment shaft 74 of the lower clamping mechanism by a manipulator, and then the lower abutment shaft 42 of the upper clamping mechanism descends. After the lower abutment shaft 42 abuts against the rotor, the driving mechanism 44 drives the lower abutment shaft 42 to rotate, so that the lower abutment shaft 42 rotates relative to the rotor, and the clamping structure of the lower abutment shaft 42 is directly clamped with the rotor, and then the lower abutment shaft 42 drives the rotor to rotate, and the rotor is rotated to a preset orientation angle. Then, under the action of the servo screw, the lower shaft 42 moves downward, and at the same time, the upper shaft 74 of the lower clamping mechanism moves downward accordingly, and the lifting cylinder 75 provides a corresponding balancing force. In this way, the rotor clamped between the lower shaft 42 and the upper shaft 74 will be accurately moved to the corresponding height position in the magnetizing box 30, and the magnetizing box 30 is started to magnetize the rotor. After the magnetization is completed, the lifting cylinder 75 drives the upper shaft 74 to rise, and the servo screw cooperates accordingly, and the rotor rises to the corresponding detection height position, and then the detection mechanism 80 is started, and the detection head 82 detects the magnetization amount on the surface of the rotor.

[0047] In summary, the single-station magnetization detection device provided by the present invention clamps the rotor through a lifting and clamping mechanism and can be limited to a corresponding height position, so that the rotor can be magnetized at a height corresponding to the magnetization position. After the magnetization is completed, the rotor is lifted to the corresponding detection mechanism, and the magnetization amount is detected by the detection mechanism. The magnetization and detection can be integrated in one station, which greatly simplifies the structure of the device, saves layout space, and greatly simplifies the device structure.

[0048] Furthermore, the lifting and clamping mechanism adopts a structure in which an upper clamping mechanism and a lower clamping mechanism cooperate. In particular, the lower abutment shaft of the upper clamping mechanism cooperates with multiple components to achieve the goal of first pressing the rotor to prevent it from moving while the shaft portion rotates. After the shaft portion of the lower abutment shaft is engaged with the rotor, the rotor is driven to rotate, thereby achieving the goal of accurately adjusting the positioning angle of the rotor and improving magnetization efficiency.

[0049] The above-described embodiments only express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
