Description

Technical Field

[0001] The invention relates to the technical field of motor rotor processing, and in particular to a feeding device for motor rotor processing. Background Art

[0002] The motor rotor is generally speaking the rotating part of the motor. The motor consists of two parts: the rotor and the stator.

[0003] During the processing of the motor rotor, the motor rotor is fed through the sleeve. However, the feeding devices for motor rotor processing currently used are mostly simple in structure. Most of them manually place the rotor in the sleeve on the feeding tray, insert the shaft, and rotate the feeding tray to the bottom of the hydraulic punch. The hydraulic cylinder pushes the hydraulic punch down to press the shaft into the rotor. After pressing, it is easy to cause damage between the outside of the motor rotor and the inner wall of the sleeve, and also reduce the feeding efficiency. When the rotor is placed in the sleeve, there is a certain gap between the inner wall of the sleeve and the outer wall of the rotor, which may cause the rotor to deviate and affect the subsequent pressing of the shaft.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Example 1: Reference Figure 1-10A feeding device for machining a motor rotor comprises a feeding plate 1 which rotates electrically and a pressing unit 3 for pressing a rotating shaft 12 into a rotor 11. A plurality of sleeves 2 are arranged in an annular pattern at the top of the feeding plate 1. A truncated cone-shaped groove 604 is formed on the inner wall of the sleeve 2, and the diameter of the groove decreases from top to bottom.

[0038] The inner wall of the truncated cone groove 604 is slidably connected and fits with the inner wall thereof, the truncated cone clamping sleeve comprises a lifting plate 601, clamping plates 602 are arranged in a circular array around the lifting plate 601, cylindrical grooves 603 are formed on the inner sides of the plurality of clamping plates 602 for placing the rotor 11, the connection between the bottom end of the clamping plate 602 and the lifting plate 601 is arranged to be rotatably connected, a connecting frame 607 is fixedly installed on the bottom end of the lifting plate 601, a vertical groove 605 is provided on the outer side of the clamping plate 602, a tension spring 606 is provided on the inner wall of the vertical groove 605, the two ends of the tension spring 606 are respectively fixedly connected to the top of the connecting frame 607 and the inner wall of the vertical groove 605, and an adjusting component for driving the lifting plate 601 to be lifted and lowered is installed on the bottom end of the lifting plate 601;

[0039] When the lifting plate 601 moves upward along the inner wall of the truncated cone groove 604, as the diameter of the truncated cone groove 604 gradually increases from bottom to top, the restraint on the clamping plate 602 becomes looser and the clamping plate 602 is affected by the tension of the tension spring 606 and opens outward, thereby increasing the opening at the top end thereof;

[0040] When the lifting plate 601 descends along the inner wall of the truncated cone groove 604, as the diameter of the truncated cone groove 604 gradually decreases from top to bottom, the clamping plate 602 is increasingly constrained, and the clamping plate 602 is restricted by the truncated cone groove 604 to pull the tension spring 606 inward, thereby restricting the rotor 11 placed inside.

[0041] The pressing unit 3 includes: a support frame 10, a hydraulic cylinder 2 302 is fixedly installed on the top of the support frame 10, an output end of the hydraulic cylinder 2 302 passes through the support frame 10 and is fixedly connected to a lifting plate 303, a punch rod 304 is fixedly connected to the bottom end of the lifting plate 303, and a punch block 305 is fixedly connected to the bottom end of the punch rod 304. By controlling the hydraulic cylinder 2 302 to push the lifting plate 303 to drive the punch rod 304 and the punch block 305 to descend, the rotating shaft 12 is pressed into the rotor 11;

[0042] The four corners of the lifting plate 303 are slidably connected to the inner sides of the guide rods 101, and the inner top of the top support frame 10 of the guide rods 101 is fixedly connected. When the hydraulic cylinder 2 302 drives the lifting plate 303 to rise and fall, it moves along the outer wall of the guide rods 101 to guide it.

[0043] In the present invention, the rotor 11 with the rotating shaft 12 inserted is placed inside the multiple clamping plates 602, and the lifting plate 601 is driven down by the adjusting component to drive the multiple clamping plates 602 to gather and clamp and fix the rotor 11, and the rotor 11 is sent to the bottom of the pressing unit 3 by the rotatable feeding plate 1, and the hydraulic cylinder 2 302 of the pressing unit 3 is controlled to push the lifting plate 303 to drive the punch rod 304 and the punch block 305 to descend, so as to press the rotating shaft 12 into the rotor 11;

[0044] After the pressing is completed, the control and adjustment component drives the lifting plate 601 to rise. As the diameter of the truncated cone groove 604 gradually increases from bottom to top, the restraint on the clamping plate 602 becomes looser and looser. The clamping plate 602 is affected by the tension of the tension spring 606 and opens outward to increase the opening at the top, making it easier to remove it.

[0045] Reference Figure 2-3 , the outer wall of the punch rod 304 is fixedly connected with a horizontal plate 401; the two sides of the horizontal plate 401 are slidably connected with slide rods 402; the bottom end of the slide rod 402 is fixedly installed with a pressure frame 404, and the bottom end of the pressure frame 404 is fixedly connected with a pressure ring 405; the outer wall of the slide rod 402 is slidably connected with a thrust spring 403, and the two ends of the thrust spring 403 are respectively fixedly connected with the bottom end of the horizontal plate 401 and the top end of the pressure frame 404;

[0046] It should be noted that before the hydraulic cylinder 2 302 of the pressing unit 3 drives the punch rod 304 and the punch block 305 to descend and contact the rotating shaft 12 through the lifting plate 303, the pressing ring 405 first contacts the rotor 11 to assist in fixing it, so that the rotor 11 is more stable;

[0047] Reference Figure 6 A spherical groove 801 is provided in a vertical array inside the clamping plate 602, and the inner side of the spherical groove 801 is set as an opening structure, and the diameter of the opening structure is smaller than the diameter of the spherical groove 801. A round rubber ball 802 is rollingly connected to the inner wall of the spherical groove 801, and the diameter of the round rubber ball 802 is larger than the diameter of the above-mentioned opening structure, and the opening structure extends from the inner side of the round rubber ball 802;

[0048] When the adjusting assembly drives the lifting plate 601 to descend, as the clamping plate 602 is restricted by the truncated cone groove 604 and pulls the tension spring 606 inward, the inner side of the circular rubber ball 802 contacts the outer wall of the rotor 11, reducing the wear on the rotor 11.

[0049] Embodiment 2: Based on Embodiment 1, refer to Figure 1 , Fig.10 , a feeding device for motor rotor processing, the adjustment component includes: an elastic spring 704, the elastic spring 704 is fixedly installed at the bottom end of the lifting plate 601;

[0050] Under normal conditions: under the influence of the thrust of the elastic spring 704, the lifting plate 601 moves upward along the inner wall of the truncated cone groove 604. As the diameter of the truncated cone groove 604 gradually increases from bottom to top, the restraint on the clamping plate 602 becomes looser and looser. Under the influence of the tension of the tension spring 606, the clamping plate 602 opens outward, thereby increasing the opening at the top end thereof.

[0051] In the feeding state: when the rotor 11 is placed inside the clamping plate 602, the lifting plate 601 will drop due to the gravity of the rotor 11, driving the clamping plate 602 to slightly gather inwards, and straightening the rotor 11;

[0052] During the pressing operation, the hydraulic cylinder 2 302 controlling the pressing unit 3 pushes the lifting plate 303 to drive the punch rod 304 and the punch block 305 to descend; before the punch block 305 descends and contacts the rotating shaft 12, the pressure ring 405 first contacts the rotor 11, and pushes the rotor 11 down through the pressure ring 405, driving the lifting plate 601 to descend along the inner wall of the truncated cone groove 604. As the diameter of the truncated cone groove 604 gradually decreases from top to bottom, the constraint on the clamping plate 602 becomes tighter and tighter. The clamping plate 602 is restricted by the truncated cone groove 604 to pull the tension spring 606 inward, thereby restricting the rotor 11 placed inside it; then, the rotating shaft 12 is pressed into the rotor 11 through the punch block 305, wherein when the punch block 305 presses the rotating shaft 12 into place, the thrust spring 403 is a rigid support in a non-retractable state, and when the punch block 305 finishes pressing and rising, the thrust spring 403 is an elastic support in a retractable state;

[0053] After the pressing is completed, the hydraulic cylinder 2 302 of the pressing unit 3 drives the lifting plate 303 to rise, thereby driving the pressing ring 405 to rise, releasing the pressure on the rotor 11 and the lifting plate 601, and then under the influence of the thrust of the elastic spring 704, the lifting plate 601 is pushed to move upward along the inner wall of the truncated cone groove 604, and the clamping plate 602 is affected by the tension of the tension spring 606 and opens outward to increase the opening of its top end, so as to facilitate the removal of the rotor 11 pressed into the rotating shaft 12;

[0054] Embodiment 3: Based on Embodiment 1, refer to Figure 1 - Figure 4 , Figure 8 , Fig. 9 , a feeding device for motor rotor processing, the adjusting component also includes: a through groove 703, the through groove 703 is opened on one side of the inner wall of the truncated cone groove 604, a horizontal plate 701 is installed on the outer side of the connecting frame 607, the outer wall of the horizontal plate 701 is slidably connected to the inner wall of the through groove 703, and the outer bottom end of the horizontal plate is fixedly connected to a hydraulic cylinder 702, and the bottom end of the hydraulic cylinder 702 is fixedly connected to the bottom end of the inner wall of the sleeve 2.

[0055] In the present invention, when the hydraulic cylinder 702 is in the extended state, the lifting plate 601 moves upward along the inner wall of the truncated cone groove 604. As the diameter of the truncated cone groove 604 increases from bottom to top, the restraint on the clamping plate 602 becomes looser and looser. The clamping plate 602 is affected by the tension of the tension spring 606 and opens outward, thereby increasing the opening at the top end thereof.

[0056] When the hydraulic cylinder 702 is in the contracted state: the lifting plate 601 descends along the inner wall of the truncated cone groove 604. As the diameter of the truncated cone groove 604 gradually decreases from top to bottom, the clamping plate 602 becomes tighter and tighter. The clamping plate 602 is restricted by the truncated cone groove 604 to pull the tension spring 606 inward, thereby clamping and fixing the rotor 11 placed inside it.

[0057] When in the contracted state, there may be a gap between the bottom end of the rotor 11 and the lifting plate 601, and the hydraulic cylinder 2 302 of the pressing unit 3 pushes the lifting plate 303 to drive the punch rod 304 and the punch block 305 to descend; before the punch block 305 descends and contacts the rotating shaft 12, the pressure ring 405 first contacts the rotor 11, and pushes the rotor 11 to adjust the state of rolling and descending on the inner wall of the spherical groove 801 through the round rubber ball 802, so that the bottom surface of the rotor 11 fits with the lifting plate 601, and at the same time, the round rubber ball 802 is used to reduce the damage to the rotor 11 caused by friction during descent.

[0058] The outer side of the hydraulic cylinder 1 702 is electrically connected with a control unit, and the control unit includes an infrared start controller 1 502 and an infrared close controller 2 503 respectively fixedly mounted on both sides of the base of the feeding tray 1; a control box 501 fixedly mounted on the outer wall of the sleeve 2 and electrically connected to the hydraulic cylinder 1 702; and an infrared receiver 504 fixedly mounted on the outer side of the control box 501 and corresponding to the infrared start controller 1 502 and the infrared close controller 2 503;

[0059] Its working principle is: the rotation of the feeding plate 1 drives the sleeve 2 to rotate, and each rotation increases the angle between the adjacent sleeve 2 and the center of the feeding plate 1;

[0060] The sleeve 2 first passes through the infrared start controller 502, and the infrared receiver 504 outside the sleeve 2 receives the first infrared beam and feeds it back to the control box 501, and the control main board inside the control box 501 sends a contraction command to the hydraulic cylinder 1 702 to control the hydraulic cylinder 1 702 to contract;

[0061] When the previous pressing is completed, it is transmitted to the bottom of the pressing unit 3 for pressing. After the pressing is completed, the infrared receiver 504 on the outside of the sleeve 2 receives the second infrared beam through the infrared closing controller 503 and feeds it back to the control box 501. The control main board inside the control box 501 sends an extension command to the hydraulic cylinder 1 702 to control the hydraulic cylinder 1 702 to extend. The infrared starting controller 502 and the infrared closing controller 503 are both infrared transmitters.

[0062] Embodiment 4: Based on any of the above embodiments, Figure 5 - Figure 7 A feeding device for processing a motor rotor, further comprising a clamping plate 901 fixedly mounted on the inner side of the top of each clamping plate 602, a conical clamping block 902 is distributed on the inner side of the clamping plate 901, a clamping groove 903 is provided on the top of the rotor 11, and the shape of the conical clamping block 902 is as follows Figure 7 As shown;

[0063] When in use, when the adjustment component drives the lifting plate 601 to descend along the inner wall of the truncated cone groove 604, as the diameter of the truncated cone groove 604 gradually decreases from top to bottom, the constraint on the clamping plate 602 becomes tighter and tighter. The clamping plate 602 is restricted by the truncated cone groove 604 to pull the tension spring 606 inward, thereby restricting the rotor 11 placed inside it, and at the same time driving the tip of the conical clamping block 902 to be inserted into the clamping groove 903. As the clamping plate 602 slowly gathers, the entire conical clamping block 902 is driven to be inserted into the clamping groove 903. The width of the tail end of the conical clamping block 902 is the same as the width of the open end of the clamping groove 903. In the process of the conical clamping block 902 being clamped into the clamping groove 903, the rotor 11 may be driven to rotate slightly, and the rotor 11 is accurately positioned. During the rotation, the circular rubber ball 802 will roll to assist the rotation to reduce friction.
