Technical Field

[0001] The present invention relates to the technical field of shaft testing, and particularly to an efficient conveying and detecting device for a motor shaft. Background Art

[0002] In the motor manufacturing industry, as a core transmission component, the machining accuracy and quality stability of the motor shaft directly affect the operating efficiency and service life of the motor.

[0003] At present, after the motor has been used for a long time, the shaft inside may have the problem of deformation. The deformation of the shaft will directly affect the output accuracy of the motor. Usually, manual operation is carried out to detect the shaft in sequence; 1. During detection, the conveying link mostly relies on conveyor belts or manual handling, making it difficult to achieve precise positioning and continuous operation; 2. In the detection link, the shaft needs to be manually transferred to the detection device, which is not only time-consuming and laborious, but may also lead to deviation of the detection result due to human operation errors; 3. The compatibility of existing devices is poor. For shafts of different specifications, parameters need to be frequently adjusted or tooling needs to be replaced, further reducing the production efficiency and increasing the production cost of the enterprise; Therefore, an efficient conveying and detecting device for a motor shaft is proposed.

Multiple support frames 33 are provided, and each support frame 33 is connected to the intersection of the movable connecting rods 31. The positioning ensures consistent spacing between the support frames 33. The top of the support frame 33 is U-shaped. The rotating shaft body 4 is supported between two corresponding support frames 33. The support frame 33 is only located at the front section of the movable connecting rod 31, which can prevent the support frame 33 from shifting between the positioning frame 51 when the movable connecting rod 31 is closed, thus avoiding collisions during the loading process. The bottom side of the support frame 33 is provided with a guide block 35 to limit the movement of the movable connecting rod 31 and make the movement smoother. The bottom side of the guide block 35 is equipped with a first cylinder 34. The bottom end of the support frame 33 is connected to the telescopic end of the first cylinder 34 to facilitate the adjustment of the height of the support frame 33 and prevent the rotating shaft body 4 from colliding during the movement. Two moving slots 13 are symmetrically installed on the worktable 1. The guide blocks 35 are movably connected in the moving slots 13. Multiple guide balls are provided on the bottom surface of the guide blocks 35.

[0020] In this embodiment, multiple sets of flipping components 5 are arranged at equal intervals on the upper side of the movable connecting rod 31. Positioning frames 51 are symmetrically installed on the worktable 1, and each positioning frame 51 is equipped with a rotating disk. A flipping rod 57 is fixedly installed between the rotating disks. An outwardly protruding strip is integrally welded to the outer surface of the flipping rod 57, which can drive the flipping frame 53 to flip synchronously during rotation. The flipping rod 57 is located at the center of the rotating disk. A bidirectional lead screw 58 is also installed on the outer side of the flipping rod 57.

The position of the material support frame 33 corresponds to the position of the flipping frame 53 in the horizontal state, which facilitates smooth material receiving.

[0022] Working principle: When the equipment needs to perform conveying and testing, a batch of rotating shaft bodies 4 are placed on the inclined frame 21. The rotating shaft bodies 4 will fall from the feed port onto the rotating plate 26 along the inclined angle. Then, the rotating plate 26 is controlled to rotate at a constant speed, and the rotating shaft bodies 4 will fall in one by one. After rotating 180 degrees, the rotating shaft bodies 4 will fall into the support frame 33 through the falling channel 25. Then, the feeding screw is controlled to rotate to adjust the position of the feeding frame 22 so that the falling channel 25 corresponds to the position of the next support frame 33. Then, the placement is repeated until all the support frames 33 are placed, and then the equipment is returned to its original position. Then, the intermediate lead screw 18 is controlled to rotate, and the guide plate 32 will move outward. During the movement, the movable connecting rod 31 will gradually open, and the support frame 33 will move with the movable connecting rod 31. When the guide plate 32 moves to the designated position, the rotating shaft body 4 will reach the designated flipping position. Then, the first cylinder 34 is controlled to extend, raising the rotating shaft body 4 to a height that matches the flipping frame 53. Then, the rotary motor 59 is controlled to rotate, and the bidirectional lead screw 58 will start to rotate. The flipping frames 53 on both sides will move towards the middle until they reach the bottom of both ends of the rotating shaft body 4. Then, the movable toothed plate 14 is controlled to push forward, and the movable gear 52 will drive the flipping rod 57 to rotate. The flipping frame 53 will move accordingly. During the movement, the flipping frame 53 will rotate the rotating shaft body 4 by ninety degrees, thereby completing the conveying of the rotating shaft body 4.

[0023] Example 2: Reference Figure 9-17 Based on Embodiment 1, the following technical solutions are also provided: Multiple rollers 56 are symmetrically installed on the bottom side of the tilting frame 53. The rotating shaft body 4 is connected to the rollers 56, and a friction rubber layer is provided on its outer surface. The rollers 56 and the rotating shaft body 4 rotate synchronously due to friction. A rotation sensor is connected to the rollers 56, and a controller is connected to the worktable 1. The rotation sensor, controller, and drive motor 543 are connected by a signal connection, which can monitor whether the rotating shaft body 4 rotates during the rotation of the drive motor 543. Multiple buffer rods 542 are arranged on the top surface of the tilting frame 53 to prevent the friction drive wheel 541 from hitting the rotating shaft body 4 due to gravity during the tilting process. The bottom ends of the buffer rods 542 are fixedly installed on the top surface of the lifting shell 54. The top ends of the buffer rods 542 and the tilting frame 53 are connected by a spring to reduce the impact force during tilting. Pressure rod 55 The device includes an inner rod and an outer rod. The outer rod is spring-connected to the fixed end of the inner rod. Multiple electric lifting rods 111 are installed on the worktable 1. A lifting frame 11 is provided on the telescopic end of the electric lifting rod 111. One side of the lifting frame 11 is arc-shaped. The top of the outer rod is connected to the bottom surface of the lifting frame 11 and acts to apply pressure to the lifting housing 54 to ensure a tight connection between the friction drive wheel 541 and the rotating shaft body 4. The friction drive wheel 541 is provided with knurled surfaces. A drive shaft is rotatably connected between the inner walls of the lifting housing 54. The friction drive wheel 541 is mounted on the drive shaft. A first bevel tooth is installed on the outer surface of the drive shaft. A drive motor 543 is installed on the top surface of the lifting housing 54. A second bevel tooth is provided on the output end of the drive motor 543. The first bevel tooth and the second bevel tooth mesh with each other to drive the rotation of the friction drive wheel 541.

[0024] A base frame 64 is horizontally mounted on the outer surface of the electric lifting rod 111. Multiple second cylinders 63 are arranged on the base frame 64. A conveyor frame 61 is horizontally connected to the telescopic ends of the second cylinders 63. A micro motor 65 is mounted on one side of the conveyor frame 61. A test lead screw is mounted on the output end of the micro motor 65. The tail end of the conveyor plate 62 is threaded to the outside of the test lead screw to facilitate the forward and backward adjustment of the test rod 66. The test rod 66 is spring-connected to the front end of the conveyor plate 62. A small ball bearing is mounted on the top of the test rod 66, continuously connected to the bottom side of the center position of the rotating shaft body 4. A connecting frame 622 is fixedly mounted on the bottom surface of the front end of the conveyor plate 62. A central shaft is mounted on the bottom end of the connecting frame 622, passing through the front section of the lever 67. Based on the lever's motion principle, it amplifies and displays the minute range of motion. The lever 67... A limit frame 68 is also installed on the bottom surface of the conveyor plate 62, which is rotatably connected to the outer surface of the central shaft. The tail end of the lever 67 is limited and connected inside the limit frame 68. A scale bar is provided on the limit frame 68, and a position sensor is provided inside the scale bar. An indicator light 621 is installed on the tail end of the conveyor plate 62, which can change color according to the position of the pointer 69. The indicator light 621 and the position sensor are electrically connected. The test rod 66 is located at the center of the flip frame 53 to ensure that its top end contacts the bottom surface of the center of the rotating shaft body 4. The test rod 66 is movably connected between the rotating shaft body 4 and the bidirectional lead screw 58.

[0025] Working principle: During the flipping process of the tilting frame 53, the tilting frame 53 will lift the rotating shaft body 4 upward. The rotating shaft body 4 will first roll onto the roller 56 along the angle of the tilting frame 53. During the flipping, due to gravity, the lifting shell 54 will move downward. The spring can relieve the impact force when the lifting shell 54 descends and reduce the impact force when the friction drive wheel 541 contacts the rotating shaft body 4. During the flipping process of the tilting frame 53, the top of the pressure rod 55 will abut against the bottom surface of the lifting frame 11. At this time, the spring between the pressure rods 55 is compressed, realizing mechanical pressure on the lifting shell 54. At this time, the contact pressure between the friction drive wheel 541 and the rotating shaft body 4 increases. According to the different dimensions of the rotating shaft body 4, the different heights of the electric lifting rod 111 are controlled to realize the adjustment of the preload force. This makes it easy for the friction drive wheel 541 to be firmly pressed on the rotating shaft body 4, reducing the occurrence of slippage. When testing the middle position of the rotating shaft body 4, before the flipping frame 53 flips, the micro motor 65 is controlled to rotate, adjusting the conveyor plate 62 to the center position of the bottom side of the rotating shaft body 4. After the flipping frame 53 completes the flipping operation, the conveyor plate 62 is adjusted to one side of the rotating shaft body 4, and then the second cylinder 63 is controlled to extend upwards. The bottom end of the test rod 66 will contact the center position of the bottom surface of the rotating shaft body 4 until the test rod 66 presses the lever 67 down to a horizontal state. At this time, the pointer 69 is zeroed, and the indicator light 621 shows a green light. Then, the micro motor 65 is controlled to rotate again, and the test rod 66 will move along the horizontal direction. The test rod 66 will move along the bottom surface of the rotating shaft body 4 in a straight line. Linear motion: When the shaft body 4 is not bent, the indicator light 621 will always remain green. When the shaft body 4 is bent, when the test rod 66 moves to the upward bending position, under the action of the spring, the test rod 66 will push upward, one end of the lever 67 will move upward, and the pointer 69 will point to the lower half of the scale. When the test rod 66 moves to the downward bending position, the test rod 66 will be squeezed downward, and at this time, one end of the pointer 69 will point to the upper half of the scale. In both cases, the indicator light 621 will show red for a period of time. The test result will be recorded and displayed in the controller in the form of a curve, indicating that there is deformation on the bottom side of the shaft body 4. Then, the drive motor 543 is controlled to rotate, and the friction drive wheel 541 drives the rotating shaft body 4 to rotate. After a small rotation, it stops. During the rotation, the friction drive wheel 541 drives the rotating shaft body 4 to rotate slowly, and the rotating shaft body 4 drives the roller 56 to rotate. This process ensures that the rotating shaft body 4 does not slip during rotation. If the roller 56 is not driven to rotate when the drive motor 543 rotates, the rotating shaft body 4 may slip and needs to be dealt with in time to avoid the same position being checked every time. After the rotating shaft body 4 rotates slightly, the movement of the conveyor plate 62 is repeated to perform the bending test again. Then, the rotating shaft body 4 is rotated slightly again to continue the test. If multiple test results show a certain amplitude of pointer 69 amplitude in the same area during the test, it indicates that the rotating shaft body 4 in that area is bent. After the test is completed, a batch of rotating shaft bodies 4 is taken out and the next batch of rotating shaft bodies 4 is tested. When it is necessary to test the end of the rotating shaft body 4, it needs to be moved to the middle position of the flipping rod 57 in advance when the flipping frame 53 flips, so that it is supported in the middle position of the rotating shaft body 4. Then repeat the above operation and use the test rod 66 to test the bottom of the rotating shaft body 4. Before the test, the conveyor plate 62 can also be moved to the middle position of the rotating shaft body 4. During the test, it is moved to the end position of the rotating shaft body 4 to complete the test.
