Description

Technical Field

[0001] The invention relates to the field of motor production, and in particular to a stator detection device. Background Art

[0002] The stator is one of the main components of the motor, which consists of an iron core, windings, and insulating materials. During the manufacturing process, if the stator has defects or poor characteristics, it may cause problems such as unstable motor operation, low efficiency, and high noise. The motor stator size refers to the dimensional parameters such as the outer diameter, inner diameter, and length of the motor stator core. These parameters directly affect the output power, efficiency, and stability of the motor, so when designing and manufacturing the motor, it must be processed and assembled strictly in accordance with the specified dimensions.

[0003] The method and steps for measuring the size of the motor stator mainly include: 1. Measuring the outer diameter of the motor stator core; measuring the outer diameter of the motor stator core requires the use of measuring tools such as an outer diameter caliper or an outer diameter micrometer. Use an outer diameter caliper or an outer diameter micrometer to measure the diameter of the motor stator core along the outside. During the measurement process, it is important to keep the measuring tool perpendicular to the axis of the motor stator core. 2. Measuring the inner diameter of the motor stator core; measuring the inner diameter of the motor stator core requires the use of measuring tools such as an inner diameter caliper or an inner diameter micrometer. Use an inner diameter caliper or an inner diameter micrometer to measure the diameter of the motor stator core along the inside. During the measurement process, it is important to keep the measuring tool perpendicular to the axis of the motor stator core. 3. Measuring the length of the motor stator core; measuring the length of the motor stator core requires the use of measuring tools such as a tape measure. Use a tape measure to measure the length of the motor stator core along the axis. During the measurement process, it is important to keep the tape measure straight and align it with the axis of the motor stator.

[0004] In the actual production process, due to the large number of measurement items, it is usually impossible to perform synchronous detection, and it needs to be carried out in sections. First, the inner diameter is detected, and then the outer diameter is detected at the next station, and then the height is detected at the next station. In this way, positioning is required before each detection to ensure the accuracy of the measurement results. This will not only increase the overall volume of the production line, but also require a greater investment of cost; therefore, the present invention proposes a stator detection device to solve the above problems.

[0011] Transmission rod three, transmission rod four and the deceleration mechanism can be transmitted and relatively still, so that the transmitter and the receiver can move synchronously or relatively independently, thereby ensuring that both can move into place. Under the action of the deceleration transmission mechanism, they can also be displaced synchronously with the electronic micrometer, realizing synchronous adjustment of the four and synchronous positioning, thereby improving the efficiency of detection.

[0044] The following is combined with Figure 1 - Attachment Fig.10 The present invention is described in further detail. Example

[0045] A stator detection device, referring to Figure 1 , Figure 2 , pictures and Figure 5 , including a conveying mechanism for conveying the stator, a clamping mechanism for clamping the stator is arranged above the conveying mechanism, and the clamping mechanism includes a clamping plate 31 fixed to the stand 2, and three clamping claws 32 movably connected to the inner side of the clamping plate 31.

[0046] Reference Figure 1-Figure 3 , the measuring mechanism is located at the position to be processed, the stator is pushed to the inner side of the clamping mechanism by the conveying mechanism below, the conveying mechanism includes a workbench 11, and an intermediate table 13 is welded at the center of the workbench 11, and conveyor belts 12 for transmitting the stator are arranged on both sides of the intermediate table 13, and guide plates 14 for adjusting the position of the stator are also arranged on both sides of the intermediate table 13, a hydraulic cylinder 15 is fixedly connected below the intermediate table 13, and a push rod 16 for vertically transmitting the position of the stator is fixedly connected to the output end of the hydraulic cylinder 15;

[0047] The position of the clamping jaw 32 and the position of the push rod 16 are staggered to avoid mutual interference when loading and unloading the stator. A stage 321 is also provided below the clamping jaw 32 to support the stator to avoid axial displacement. During the clamping process, the clamping jaw 32 is first moved to a position that matches the stator clearance. At this time, the stator will be placed on the stage 321 under the action of gravity, and then the clamping jaw 32 is retracted for a second time to ensure the stability of the initial position of the stator, thereby improving the accuracy of the measurement result.

[0048] Reference Figure 1 , Figure 2 , Figure 4-Figure 7 The measuring mechanism includes an electronic micrometer 5 for measuring the inner and outer diameters of the stator and a laser distance sensor for detecting the height of the stator. The transmitter 74 and the receiver 75 of the laser distance sensor are aligned in the upper and lower rows.

[0049] Reference Figure 1 and Figure 2 A horizontally movable measuring mechanism is arranged above the clamping mechanism, a platform 2 is arranged on the outside of the clamping mechanism, and a bracket 42 cooperating with the measuring mechanism is arranged above the platform 2. The bottom end of the bracket 42 is movably connected to the platform 2 through two linear modules 41. The linear module 41 drives the bracket 42 to move horizontally, thereby changing the position of the measuring mechanism. When the measurement is completed, the linear module 41 drives the measuring mechanism to move to one side. At this time, the transmission rod 472 below no longer contacts the end of the stator. The hydraulic cylinder 15 pushes the push rod 16 to the bottom of the stator. After the clamping mechanism releases the stator, the stator can be transported from the bottom of the platform 2 to the outside. The push rod 16 will subsequently push the stator to be tested to the inside of the clamping mechanism for subsequent testing. During the secondary clamping of the stator to be tested, the linear module 41 drives the overall measuring mechanism to reset and enter the position to be tested. After the stator clamping operation is completed, the transmission mechanism drives each part of the measuring mechanism to enter the detection position.

[0050] Reference Figure 1 and Figure 2 A hydraulic cylinder 2 43 is welded at the center position of the bracket 42, and the output end of the hydraulic cylinder 2 43 is rotatably connected to the intermediate shaft 44 through a connecting plate, and a motor 1 45 for circumferentially transmitting the intermediate shaft 44 is fixedly connected to the connecting plate. When the motor 1 45 rotates, the intermediate shaft 44 is driven to rotate through a synchronous belt transmission structure. Since the radial positions of the intermediate shaft 44 and the measuring mechanism are fixed, the measuring mechanism will rotate synchronously with the intermediate shaft 44, thereby detecting 360° inside and outside the stator. The detected data is transmitted to an external terminal via a signal transmission system for recording. The electronic micrometer 5 uses the initial contact position as the preset "0" position, and subsequent measurement results are compared with it to determine the smoothness of the inner and outer diameters of the stator. The photoelectric sensor transmits the data of each detection interval in real time and compares them to determine the flatness of the stator height.

[0051] Reference Figure 4-Figure 10 The measuring mechanism further comprises an intermediate shaft 44 which rotates in a circumferential direction, a transmission mechanism is arranged on the inner side of the intermediate shaft 44, a transmission rod 3 71 for installing the position of the transmitter 74 is arranged on the outer side of the transmitter 74, and a transmission rod 4 72 for installing the position of the receiver 75 is arranged on the outer side of the receiver 75, and the transmission rod 3 71 and the transmission rod 4 72 are synchronously slid relative to each other in the vertical direction under the action of the transmission mechanism, or their positions are stationary relative to the gears in the transmission mechanism;

[0052] The transmission mechanism includes a planetary gear reduction system consisting of a ring gear 83, three planetary gears 84 and a sun gear 85. The sun gear 85 extends to a position between the transmission rod 3 71 and the transmission rod 4 72. The planetary gear 84 is fixedly connected to the transmission wheel 86 through a planet carrier. An adjustment ring 82 is fixedly connected to the outer side of the ring gear 83, and the adjustment ring 82 and the intermediate shaft 44 are fixedly connected by bolts. The motor 2 81 is also fixedly connected to the adjustment ring 82 by bolts. The output shaft of the motor 2 81 and the sun gear 85 are coaxially fixedly connected. A number of spring teeth 76 are evenly distributed on the side walls of the transmission rod 3 71 and the transmission rod 4 72 near the sun gear 85. One side of the spring teeth 76 is fixedly connected to the side wall of the transmission rod. The other side is suspended, and the spring teeth 76 of the transmission rod three 71 and the transmission rod four 72 are symmetrically arranged. The transmission rod three 71 and the transmission rod four 72 are provided with grooves 712 for the spring teeth 76 to sink into. The fixed side of the spring teeth 76 of the transmission rod three 71 is located at the top. When the sun gear 85 rotates, it will push the transmission rod three 71 to move downward as a whole. When the transmission rod three 71 moves into place, but the transmission rod four 72 does not move into place, if the sun gear 85 still needs to move at this time, the card teeth of the sun gear 85 will squeeze the spring teeth 76, so that the spring teeth 76 are recessed into the inside of the groove 712, thereby keeping the sun gear 85 and the transmission rod three 71 relatively stationary, and the transmission rod four 72 is kept in a relatively stable state. The old can be displaced under the action of the sun gear 85. The fixed side of the spring tooth 76 of the transmission rod four 72 is located at the bottom. Its working principle is the same as that of the transmission rod three 71. Both can be stationary relative to the position of the sun gear 85 at the same time. When the transmission rod three 71 and the transmission rod four 72 are moved to the right position, the sun gear 85 stops running, and the movement of the transmission rod three 71 and the transmission rod four 72 can be monitored by an external CCD camera module, or by adding a strain sensor to the horizontal section of the transmission rod three 71 and the transmission rod four 72. The transmission rod three 71 is provided with a through hole 711 for the transmission rod four 72 to be displaced. When measuring a stator with a smaller height, the transmission rod four 72 can pass through the transmission rod three 71 to ensure that the horizontal sections of the transmission rod three 71 and the transmission rod four 72 are kept at a fixed distance from the stator end. The ends of the transmission rod three 71 and the transmission rod four 72 are welded with ball seats 73 on the side close to the stator, and the ball seats 73 are used to achieve smooth displacement on the stator; the transmission rod three 71 and the transmission rod four 72 are arranged on both sides of the sun gear 85. When the horizontal sections of the transmission rod three 71 and the transmission rod four 72 are close to each other, the two electronic micrometers 5 are also synchronously close to each other under the action of the planetary gear reduction system. When the transmission rod three 71 and the transmission rod four 72 are away from each other, the two electronic micrometers 5 are also synchronously away from each other under the action of the planetary gear reduction system.

[0053] Reference Figure 4-Figure 8The transmission mechanism also synchronously reduces the speed of the transmission for the relative displacement of the two inner and outer diameter measuring electronic micrometers 5; a transmission rod 61 is fixedly connected to the electronic micrometer 5 for measuring the outer diameter, and a transmission rod 2 62 is fixedly connected to the electronic micrometer 5 for measuring the inner diameter. The transmission rod 61 and the transmission rod 2 62 are respectively engaged with the upper and lower sides of the transmission wheel 86. The front end of the electronic micrometer 5 for measuring the inner diameter can be modified accordingly, and a transition piece is added to prevent it from falling directly into the stator slot and causing damage when the device continues to rotate. The transmission rod 61 is an inverted U-shaped structure, and the transmission rod 2 62 is a straight structure. The inverted U-shaped structure of the transmission rod 61 facilitates its top end to pass over the top edge of the stator, so that when the relative position of the measuring mechanism as a whole is adjusted inside the intermediate shaft 44 in the later stage, the transmission rod 61 will not contact the stator, thereby improving the scope of application of the device.

[0054] Reference Figure 4 , Figure 5 and Figure 7 A limit slot 441 is provided on the intermediate shaft 44, and the transmission mechanism is located inside the limit slot 441. A limit frame is provided inside the limit slot 441 to limit the horizontal position of the transmission rod 1 61 and the transmission rod 2 62, and a limit frame is provided to limit the vertical position of the transmission rod 3 71 and the transmission rod 4 72, so as to ensure that the position of each transmission rod can be stably displaced during the displacement process. The limit frame can be selected to be welded with the gear ring 83, so that when the position of the gear ring 83 is changed, the position adjustment of the overall measuring mechanism can be realized, while keeping the stability of each part. An adjustment slot 442 is also provided on the intermediate shaft 44 perpendicular to the limit slot 441.

[0055] Reference Figure 4-Figure 8 , the motor 81 drives the sun gear 85 to rotate, and the sun gear 85 then meshes and drives the transmission rod 3 71 and the transmission rod 4 72 connected to the two L-shaped structures to perform vertical displacement, the transmission rod 3 71 and the transmitter 74 go down, and the transmission rod 4 72 and the receiver 75 go up, and the sun gear 85 synchronously drives the outer planetary gear 84 and the planetary carrier to rotate, thereby making the transmission wheel 86 also rotate synchronously. Since the transmission wheel 86 is meshed with the transmission rod 1 61 and the transmission rod 2 62, the transmission rod 1 61 and the transmission rod 2 62 will be relatively displaced under the action of the transmission wheel 86 at this time, and the electronic micrometer 5 for measuring the outer wall diameter approaches the axis position, and the electronic micrometer 5 for measuring the inner wall approaches the stator side.

[0056] During the inspection, the measuring end of the electronic micrometer 5 is attached to the inner and outer walls of the stator, and the distance between the transmitter 74, the receiver 75 and the end of the stator is fixed. During the measurement process, the electronic micrometer 5 uses the position change of the measuring end to measure the inner diameter and the outer diameter and judge its smoothness. In the initial state, the positions of the transmitter 74 and the receiver 75 are fixed by the transmission rod three 71 and the transmission rod four 72 respectively. During the circular rotation of the measuring mechanism, the deformation of the horizontal sections of the transmission rod three 71 and the transmission rod four 72 is used to change the position of the transmitter 74 and the receiver 75. When the measured distance changes, it proves that the thickness of the stator at this position is different from the initial position, and finally the uniformity of the stator thickness is detected.
