Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, in particular to a conveying rack for machining motor rotors. Background Art

[0002] The motor rotor is the rotating part in the motor. The motor consists of two parts: the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into two types: inner rotor rotation mode and outer rotor rotation mode. The inner rotor rotation mode is that the core in the middle of the motor is the rotating body, outputting torque (referring to the motor) or receiving energy (referring to the generator). The outer rotor rotation mode is that the outer body of the motor is the rotating body. Different modes facilitate the application of various occasions.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 1 , Figure 4 , Figure 5 , Fig. 9 , Fig.10 and Fig.13 As shown, a conveyor frame for motor rotor processing described in the present invention includes a support block 1, a grasping structure 2 is provided in the middle of the support block 1, a driving structure 3 is provided on the side of the grasping structure 2, a lifting structure 7 is provided on the inner side of the support block 1, a telescopic structure 6 is connected between the support block 1 and the grasping structure 2, a positioning structure 4 is connected to the telescopic structure 6, and a conversion structure 5 is provided on the top side of the grasping structure 2.

The end of the grabbing rod 204 is rotatably connected to the hook rod 205, and a first torsion spring 209 is fixedly connected between the hook rod 205 and the grabbing rod 204. The side of the connecting block 201 is rotatably connected to the driving shaft 206, and the two ends of the driving shaft 206 are respectively slidably connected to the telescopic rod 210 set on the same side, and a first spring 211 is fixedly connected between the telescopic rod 210 and the driving shaft 206. A connecting sleeve rod 202 is provided between the two guide boxes 203, and the connecting sleeve rod 202 is slidably connected to the guide box 203;

[0039] A support block 1 is provided on both sides of the connecting block 201. The end of the support block 1 is an inclined structure. When the motor rotor needs to be loaded, the user needs to press the grabbing rods 204 on both sides downward. At this time, the guide box 203 will rotate, and the moving device as a whole will move the ends of the support block 1 to the bottom side of the rotating shaft on both sides of the motor rotor. At this time, the hook rod 205 at the end of the grabbing rod 204 is hooked onto the rotating shaft of the rotor. Due to the second torsion spring 213 connected between the guide box 203 and the support block 1, the grabbing rod 204 will remain in a state of conflict with the rotating shaft of the rotor. At this time, if the driving shaft 206 The rotation will drive the transmission gear 208 on the inner side of the guide box 203 to start rotating through the telescopic rod 210. The transmission gear 208 meshes with the grab rod 204 through the tooth groove 207. As the transmission gear 208 rotates, the grab rod 204 slides on the inner side of the guide box 203, and at the same time drives the motor rotor to move toward the middle of the support block 1 through the hook rod 205. At the same time, due to the inclined structure on both sides of the support block 1 and the limit groove 212 for the angle limit of the guide box 203, the rotor will gradually move to the top side of the support block 1 through the traction of the grab rod 204 until the rotor is fixed.

[0040] Specifically, Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig. 9As shown, the driving structure 3 includes a worm gear sleeve 303, a worm gear sleeve 303 is fixedly connected to the middle part of the driving shaft 206, a worm 302 is meshed on the side of the worm gear sleeve 303, the worm 302 is rotatably connected to the connecting block 201, a plug-in block 305 is slidably connected to the end of the worm 302, a second spring 304 is fixedly connected between the plug-in block 305 and the worm 302, a handwheel 301 is rotatably connected to the side of the connecting block 201, a first bevel gear 306 is provided at the end of the handwheel 301, the end of the first bevel gear 306 is in a square rod-shaped structure, the end of the first bevel gear 306 is slidably connected to the handwheel 301, a slot 307 is provided on the side of the first bevel gear 306 away from the handwheel 301, a sliding frame 308 is rotatably connected to the first bevel gear 306, and the sliding frame 308 is slidably connected to the connecting block 201;

[0041] In order to facilitate the driving shaft 206 to rotate, a worm gear sleeve 303 is provided in the middle of the driving shaft 206. When the sliding frame 308 located on the inner side of the connecting block 201 moves to one side of the driving shaft 206, the slot 307 on the side of the first bevel gear 306 will be connected to the plug-in block 305 at the end of the worm 302. At this time, the user can drive the worm 302 to rotate by rotating the handwheel 301 on the side of the connecting block 201, and then drive the driving shaft 206 to rotate through the transmission effect between the worm 302 and the worm gear sleeve 303. Through the labor-saving effect of the worm gear sleeve 303, the worm 302 and the inclined surface, the operator can lift and store the motor rotor more labor-savingly, thereby improving work efficiency.

[0042] Specifically, Fig.13 As shown, the lifting structure 7 includes a driving screw 702, the inner side of the support block 1 is rotatably connected with the driving screw 702, the end of the driving screw 702 is fixedly connected with a fourth bevel gear 701, the threads on both sides of the driving screw 702 are in opposite directions, and a thread block 703 is threadedly connected on both sides of the driving screw 702, and the thread block 703 is slidably connected to the inner side of the support block 1, the bottom side of the thread block 703 is rotatably connected with a bearing rod 704, the middle parts of the two bearing rods 704 are rotatably connected to each other, and the other end of the bearing rod 704 is rotatably connected with a supporting foot 705, the inner side of the supporting foot 705 is rotatably connected with a pulley 706, and the inner side of the supporting foot 705 is rotatably connected with two pulleys 706, the end of the support block 1 is an inclined structure, and a pushing block 707 is slidably connected to the top side of the support block 1, and a sixth spring 708 is fixedly connected between the pushing block 707 and the support block 1;

[0043] Due to the different specifications of different motor rotors, in order to fully support the rotor, a driving screw 702 is provided on the inner side of the support block 1 on both sides. When the driving screw 702 rotates, it can drive the two threaded blocks 703 on both sides to move in opposite directions. When the threaded block 703 moves, the two bearing rods 704 rotate relative to each other and lift the support block 1 as a whole. When the support block 1 is separated from the supporting surface, the supporting foot 705 at the bottom end of the bearing rod 704 can support the entire device through the pulley 706 on the bottom side, which is convenient for moving the device and transporting the rotor. At the same time, the pushing block 707 located on the top side of the support block 1 will maintain a resistance state with the fixed rotor shaft under the push of the sixth spring 708, thereby reducing the shaking of the rotor in a fixed state and ensuring good stability.

[0044] Specifically, Figure 5 , Fig. 9 , Fig.10 As shown, the telescopic structure 6 includes a transmission sleeve 602, the side of the support block 1 is rotatably connected to an inner slide rod 604, the end of the inner slide rod 604 is fixedly connected to a third bevel gear 603, the third bevel gear 603 is meshed with a fourth bevel gear 701, the inner side of the connecting block 201 is rotatably connected to a transmission sleeve 602, the transmission sleeve 602 is slidably connected to the inner slide rod 604, and the end of the transmission sleeve 602 is fixedly connected to a second bevel gear 601;

[0045] In order to load motor rotors of different lengths and ensure that the rotating shafts at both ends of the rotor can be supported on the support block 1, a transmission sleeve 602 and an inner slide bar 604 are provided between the support block 1 and the connecting block 201. The distance between the support block 1 and the connecting block 201 can be changed by sliding between the transmission sleeve 602 and the inner slide bar 604, thereby loading rotors of different lengths.

[0046] Specifically, Figure 1 , Figure 4 , Fig.10 , Fig.12As shown, the positioning structure 4 includes a positioning groove 405, a plurality of positioning grooves 405 are equidistantly provided on the side of the inner slide rod 604, a receiving groove 406 is provided on the side of the transmission sleeve 602, the transmission sleeve 602 is slidably connected with a positioning column 404 through the receiving groove 406, the positioning column 404 is in a capsule-shaped structure, the end of the positioning column 404 is in conflict with the inner slide rod 604 through the positioning groove 405, the transmission sleeve 602 is slidably connected with a blocking sleeve 402, a third spring 403 is fixedly connected between the blocking sleeve 402 and the connecting block 201, the end of the positioning column 404 is in conflict with the inner side of the blocking sleeve 402, the side of the connecting block 201 is rotatably connected with a rotating rod 401, and the end of the rotating rod 401 is in conflict with the side of the blocking sleeve 402;

[0047] When adjusting the distance between the connecting block 201 and the supporting block 1, the user first needs to rotate the rotating rod 401 located on the side of the connecting block 201 so that the end of the rotating rod 401 pushes the blocking sleeve 402 to slide to one side until the blocking sleeve 402 no longer conflicts with the positioning column 404 on the transmission sleeve 602. At this time, the positioning column 404 can slide freely in the avoidance groove, thereby allowing the transmission sleeve 602 and the inner slide bar 604 to freely extend and retract. When adjusted to a suitable distance, the rotating rod 401 is released. At this time, the blocking sleeve 402 returns to its position under the push of the third spring 403. At this time, the positioning column 404 is again blocked by the blocking sleeve 402, thereby preventing the transmission sleeve 602 and the inner slide bar 604 from sliding, thereby achieving width positioning.

[0048] Specifically, Figure 1 , Figure 5 , Figure 6 As shown, the conversion structure 5 includes a conversion rod 501, the top side of the connecting block 201 is rotatably connected with the conversion rod 501, both sides of the conversion rod 501 are respectively provided with protrusion structures, the inner side of the connecting block 201 is provided with a fixing groove 502, the protrusion on the side of the conversion rod 501 is engaged with the connecting block 201 through the fixing groove 502, the bottom side of the conversion rod 501 is in contact with a contact washer 503, a fourth spring 504 is fixedly connected between the contact washer 503 and the connecting block 201, the bottom end of the conversion rod 501 is slidably connected with a rotating rod 505, the eccentric position of the bottom end of the rotating rod 505 is fixedly connected with a sliding column 506, the top side of the sliding frame 308 is provided with a transverse groove 507, and the sliding column 506 is slidably connected with the sliding frame 308 through the transverse groove 507;

[0049] In order to facilitate the user to drive the drive shaft 206 and the transmission sleeve 602 separately, the user only needs to adjust the position of the sliding frame 308. When the sliding frame 308 slides to one side of the drive shaft 206, the meshing state between the first bevel gear 306 and the second bevel gear 601 is released, and the first bevel gear 306 is connected to the worm 302. At this time, the user turns the hand wheel 301 to drive the grab rod 204 to grab and load the rotor. When the sliding frame 308 slides to the other side, the first bevel gear 306 is meshed with the second bevel gear 601. At this time, the user turns the hand wheel 301 to 04 drives the driving screw 702 to rotate, thereby adjusting the height of the support block 1, which is convenient for loading rotors of different heights. At the same time, when the pulley 706 is no longer in contact with the supporting surface, the rotor can be transported by the entire device through a conveying tool such as a conveyor belt. When making adjustments, the user needs to press the conversion rod 501 located on the top side of the connecting block 201 to make the two protrusions at the bottom disengage from the fixing groove 502. At this time, the conversion rod 501 is rotated to adjust the direction of the two protrusions, so that the sliding column 506 at the end of the rotating rod 505 on the bottom side slides in the horizontal groove 507 of the sliding frame 308, and the position of the sliding frame 308 can be adjusted and fixed.

[0050] When the present invention is in use, first, a support block 1 is provided on both sides of the connecting block 201, and the end of the support block 1 is an inclined structure. When the motor rotor needs to be loaded, the user needs to press the grabbing rods 204 on both sides downward, and the guide box 203 will rotate at this time, and the moving device as a whole makes the ends of the support block 1 move to the bottom side of the rotating shaft on both sides of the motor rotor. At this time, the hook rod 205 at the end of the grabbing rod 204 is hooked on the rotating shaft of the rotor. Due to the second torsion spring 213 connected between the guide box 203 and the support block 1, the grabbing rod 204 will maintain a state of being in conflict with the rotating shaft of the rotor. At this time, if the driving shaft 206 rotates, the transmission gear 208 on the inner side of the guide box 203 will start to rotate through the telescopic rod 210, and the transmission gear 208 will mesh with the grabbing rod 204 through the tooth groove 207. As the transmission gear 208 rotates, the grabbing rod 204 slides on the inner side of the guide box 203, and at the same time, the motor rotor is driven to the support block through the hook rod 205. 1, and at the same time, due to the inclined surface structure on both sides of the support block 1 and the limiting groove 212 for the angle limit of the guide box 203, the rotor will gradually move to the top side of the support block 1 through the traction of the grab rod 204 until the rotor is fixed. In order to facilitate the driving of the drive shaft 206 to rotate, a worm gear sleeve 303 is provided in the middle of the drive shaft 206. When the sliding frame 308 located on the inner side of the connecting block 201 moves to one side of the drive shaft 206, the slot 307 on the side of the first bevel gear 306 will be connected with the plug-in block 305 at the end of the worm 302. At this time, the user can drive the worm 302 to rotate by rotating the hand wheel 301 on the side of the connecting block 201, and then drive the drive shaft 206 to rotate through the transmission effect between the worm 302 and the worm gear sleeve 303. Through the labor-saving effect of the worm gear sleeve 303, the worm 302 and the inclined surface, the operator can lift and store the motor rotor more labor-savingly, thereby improving work efficiency.

[0051] Due to the different specifications of motor rotors, in order to fully support the rotor, driving screws 702 are provided on the inner sides of the support blocks 1 on both sides. When the driving screws 702 rotate, the two threaded blocks 703 on both sides can be driven to move in opposite directions. When the threaded blocks 703 move, the two bearing rods 704 rotate with each other and lift the support block 1 as a whole. When the support block 1 is separated from the supporting surface, the supporting feet 705 at the bottom ends of the bearing rods 704 can support the device as a whole through the pulleys 706 on the bottom side, which is convenient for moving the device and transporting the rotor. At the same time, the pushing block 707 on the top side of the support block 1 will maintain a state of conflict with the fixed rotor shaft under the push of the sixth spring 708, thereby reducing the rotor from being moved. The shaking in the fixed state ensures good stability. In order to load motor rotors of different lengths and ensure that the rotating shafts at both ends of the rotor can be carried on the support block 1, a transmission sleeve 602 and an inner slide rod 604 are provided between the support block 1 and the connecting block 201. The distance between the support block 1 and the connecting block 201 can be changed by sliding between the transmission sleeve 602 and the inner slide rod 604, so as to load rotors of different lengths. When adjusting the distance between the connecting block 201 and the support block 1, the user first needs to rotate the rotating rod 401 located on the side of the connecting block 201 so that the end of the rotating rod 401 pushes the blocking sleeve 402 to slide to one side until the blocking sleeve 402 no longer conflicts with the positioning column 404 on the transmission sleeve 602. , at this time, the positioning column 404 can slide freely in the avoidance groove, thereby allowing the transmission sleeve 602 and the inner slide rod 604 to freely extend and retract. When adjusted to a suitable distance, the rotating rod 401 is released, and the blocking sleeve 402 is pushed back to its position by the third spring 403. At this time, the positioning column 404 is blocked by the blocking sleeve 402 again, thereby preventing the transmission sleeve 602 and the inner slide rod 604 from sliding, thereby achieving width positioning. In order to facilitate the user to drive the drive shaft 206 and the transmission sleeve 602 separately, the user only needs to adjust the position of the sliding frame 308 to achieve it. When the sliding frame 308 slides to one side of the drive shaft 206, the first bevel gear 306 and the second bevel gear 601 are released. The first bevel gear 306 is in meshing state, and the first bevel gear 306 is connected to the worm 302. At this time, the user turns the hand wheel 301 to drive the grab rod 204 to grab and load the rotor. When the sliding frame 308 slides to the other side, the first bevel gear 306 is meshed with the second bevel gear 601. At this time, the user turns the hand wheel 301 to drive the driving screw 702 to rotate through the transmission sleeve 602 and the inner slide rod 604, so as to adjust the height of the support block 1, which is convenient for loading rotors of different heights. At the same time, when the pulley 706 is no longer in contact with the supporting surface, the rotor can be transported by the device as a whole by means of a conveying tool such as a conveyor belt. When adjusting, the user needs to press the conversion rod 501 located on the top side of the connecting block 201.The two protrusions at the bottom end are separated from the fixing groove 502. At this time, the conversion rod 501 is rotated to change the direction of the two protrusions, so that the sliding column 506 at the end of the bottom rotating rod 505 slides in the horizontal groove 507 of the sliding frame 308, and the position of the sliding frame 308 can be adjusted and fixed.
