Description

Technical Field

[0001] This utility model relates to a motor rotor stacking device, belonging to the field of new energy motor processing technology. Background Technology

[0002] The motor rotor is the rotating component of an electric motor. An electric motor consists of a rotor and a stator, and it is a device used to convert electrical energy into mechanical energy and vice versa. By arranging laminated iron cores on the motor rotor, eddy currents and other losses can be reduced, avoiding or mitigating torque reduction at high speeds. Generally, to prevent eddy current losses caused by higher harmonics on the surface of the motor rotor core, the surface of the rotor core is not machined. This necessitates improving the coaxiality during the lamination process of the rotor.

[0003] However, current pressing equipment is prone to uneven stress during the pressing of motor rotor laminations, which can cause deformation of the bottom pads and thus affect the pressing quality of the laminations.

[0004] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a motor rotor stacking device that has greater industrial application value. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a motor rotor stacking device.

[0006] This utility model discloses a motor rotor stacking device, comprising a stacking top plate. The four corners of the bottom of the stacking top plate are fixedly connected to the top of a feeding mechanism via four vertical support columns. A sliding sleeve is slidably fitted onto the surface of each support column. A stabilizing plate parallel to the stacking top plate is fixedly connected to the sliding sleeve. A locking ring pressure block is vertically arranged downwards at the bottom of the stabilizing plate. A stacking servo cylinder is fixedly mounted on the top surface of the stacking top plate, and the bottom output end of the stacking servo cylinder is drively connected to the top surface of the stabilizing plate. The stacking servo cylinder drives the locking ring pressure block at the bottom of the stabilizing plate to press down and form the rotor to be stacked. During the pressing process, since the sliding sleeve can only move directionally up and down along the support columns, the stabilizing plate and the sliding sleeve ensure that the locking ring pressure block can move directionally and stably, improving the stacking accuracy.

[0007] Furthermore, the feeding mechanism includes a horizontally arranged feeding platform, on the upper surface of the feeding platform a servo slide rail is arranged longitudinally, a servo slider is slidably sleeved on the surface of the servo slide rail, and one end of the servo slide rail is connected to a servo motor for transmission.

[0008] Furthermore, two guide rails are arranged parallel to each other on one side of the servo slide rail, and a work platform is slidably sleeved on the surface of the two guide rails. One side of the work platform is fixedly connected to the servo slider.

[0009] Furthermore, a buffer fixture is fixedly installed on the upper surface of the work platform, and the rotor to be stacked is placed on the top surface of the buffer fixture. First, the rotor to be stacked is manually installed on the surface of the buffer fixture. Then, the servo motor drives the servo slide rail to move the work platform, the buffer fixture on its surface, and the rotor to be stacked to move directly below the locking ring pressure block, and then the stacking process is performed.

[0010] Furthermore, the buffer fixture includes a buffer base at the bottom, and a fixture top plate is fixedly connected to the top of the buffer base by fixing screws. Multiple buffer springs and multiple limiting posts are evenly arranged between the buffer base and the fixture top plate. The buffer springs and limiting posts provide directional buffering and pressure equalization, thereby preventing uneven stress during the pressing of the rotor laminations, which could lead to deformation of the bottom pads and affect the quality of the lamination pressing.

[0011] Furthermore, the rotor to be stacked includes a vertically arranged rotating shaft, on which a rotor base, multiple rotor cores, a rotor top plate, and a locking ring are sequentially fitted from bottom to top on the rotating shaft surface.

[0012] By means of the above-described solution, the present invention has at least the following advantages:

[0013] (1) The motor rotor stacking equipment of this utility model uses a stacking servo electric cylinder to drive the locking ring pressure block at the bottom of the stabilizing plate to press down and stack the rotor to be stacked. During the pressing process, since the sliding sleeve can only move up and down along the support column, the locking ring pressure block can be moved in a stable direction through the action of the stabilizing plate and the sliding sleeve, thus improving the stacking accuracy.

[0014] (2) The motor rotor stacking equipment of this utility model achieves the effect of directional buffering and equalizing pressure through buffer springs and limiting columns, thereby preventing uneven force during the stacking and pressing of rotor laminations, which can easily lead to deformation of the bottom pads and thus affect the quality of lamination pressing.

[0015] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] See Figure 1A preferred embodiment of the present invention describes a motor rotor stacking device, comprising a stacking top plate 1. The four corners of the bottom of the stacking top plate 1 are fixedly connected to the top of the feeding mechanism 7 by four vertical pillars 2. A sliding sleeve 3 is slidably fitted on the surface of each pillar 2. A stabilizing plate 4 parallel to the stacking top plate 1 is fixedly connected to the sliding sleeve 3. A locking ring pressure block 6 is vertically arranged downward at the bottom of the stabilizing plate 4. A stacking servo cylinder 5 is fixedly arranged on the top surface of the stacking top plate 1. The bottom output end of the stacking servo cylinder 5 is connected to the top surface of the stabilizing plate 4. The stacking servo cylinder 5 drives the locking ring pressure block 6 at the bottom of the stabilizing plate 4 to press down and form the rotor 78 to be stacked. During the pressing process, since the sliding sleeve 3 can only move vertically along the pillar 2, the stabilizing plate 4 and the sliding sleeve 3 ensure that the locking ring pressure block 6 can move directionally and stably, thereby improving the stacking accuracy.

[0030] See Figure 2 and Figure 3 The feeding mechanism 7 includes a horizontally arranged feeding platform 71. A servo slide rail 72 is arranged longitudinally on the upper surface of the feeding platform 71. A servo slider 73 is slidably sleeved on the surface of the servo slide rail 72. One end of the servo slide rail 72 is connected to a servo motor 74. Two guide slide rails 75 are arranged parallel to each other on one side of the servo slide rail 72. A working platform 76 is slidably sleeved on the surface of the two guide slide rails 75. One side of the working platform 76 is fixedly connected to the servo slider 73. A buffer fixture 77 is fixedly installed on the upper surface of the working platform 76. A rotor 78 to be stacked is placed on the top surface of the buffer fixture 77. First, the rotor 78 to be stacked is manually installed on the surface of the buffer fixture 77. Then, the servo motor 74 drives the servo slide rail 72 to move the working platform 76, the buffer fixture 77 on its surface, and the rotor 78 to be stacked to move directly below the locking ring pressure block 6, and then the stacking process is performed.

[0031] See Figure 4 and Figure 5 The buffer fixture 77 includes a buffer base 771 at the bottom. A fixture top plate 772 is fixedly connected to the top of the buffer base 771 by fixing screws 774. A plurality of buffer springs 773 and a plurality of limiting posts 775 are evenly arranged between the buffer base 771 and the fixture top plate 772. The buffer springs 773 and the limiting posts 775 achieve the effect of directional buffering and equalizing pressure, thereby preventing uneven force during the pressing of the rotor laminations, which could lead to deformation of the bottom pads and affect the quality of the lamination pressing.

[0032] See Figure 6The rotor to be stacked 78 includes a vertically arranged rotating shaft 781, and a rotor base 782, multiple rotor cores 783, a rotor top plate 784 and a locking ring 785 are sequentially sleeved on the surface of the rotating shaft 781 from bottom to top.

[0033] The working principle of this utility model is as follows:

[0034] In actual operation, firstly, the shaft 781 of the rotor 78 to be stacked is manually inserted into the buffer fixture 77. Then, the rotor base 782, rotor core 783, rotor top plate 784, and locking ring 785 are sequentially placed on the surface of the shaft 781 from bottom to top. Then, the servo motor 74 drives the servo slide rail 72 to move the work platform 76, the buffer fixture 77 on its surface, and the rotor 78 to be stacked to be moved directly below the locking ring pressure block 6. Next, the stacking servo electric cylinder 5 drives the locking ring pressure block 6 at the bottom of the stabilizing plate 4 to press down, and the locking ring is locked by the locking ring pressure block 6. The rotor platen 784 is press-fitted into the rotor top platen 785 to form the rotor 78 to be stacked. During the pressing process, since the sliding sleeve 3 can only move vertically along the support column 2, the locking ring pressure block 6 can move directionally and stably through the action of the stabilizing plate 4 and the sliding sleeve 3, improving the stacking accuracy. During the stacking process, the buffer spring 773 and the limiting post 775 provide directional buffering and pressure equalization, thus preventing uneven force distribution during the stacking of the rotor plates, which could lead to deformation of the bottom pads and affect the stacking quality. After stacking is completed, the rotor is returned to its original position and manually unloaded, thus completing the stacking of the motor rotor.
