Description

Technical Field

[0001] The invention relates to the technical field of motor shaft detection, and in particular to a batch motor shaft diameter detection device. Background Art

[0002] The motor shaft is an important part of the motor. It carries the motor rotor and connects other transmission components. The motor shaft is usually made of metal materials, such as steel or aluminum alloy, and has sufficient strength and rigidity to withstand the rotational motion of the motor rotor and transmit torque. In practical applications, the diameter tolerance range is usually determined according to the specific purpose of the motor shaft and the application environment in which it is located. In general, the motor shaft diameter error should be controlled within the tolerance range specified by the design requirements to ensure the performance and reliability of the motor shaft. If the motor shaft diameter error exceeds the tolerance range required by the design, it may affect the running stability, transmission efficiency and other related performance of the motor. Therefore, motor shaft diameter detection is one of the important steps to ensure that the quality and size of the motor shaft meet the requirements. The motor shaft diameter has a great influence on the use and assembly of the motor shaft. Usually, the motor shaft diameter is detected by manual measurement with a ruler, which has low measurement efficiency and large manual operation errors. At the same time, it is impossible to achieve large-scale continuous measurement of the motor shaft, and the degree of automation is low. Summary of the invention

[0004] Furthermore, the feeding device includes a rotating motor fixedly mounted on the feed box, a motor gear is fixedly mounted on the motor shaft of the rotating motor, a large gear is rotatably mounted on the feed box, a transmission belt is wrapped around the large gear and the motor gear, a rotating block is rotatably mounted on the large gear, an inner telescopic rod is fixedly mounted on the rotating block, a feed block is slidably mounted on the feed box, the feed block and the inner telescopic rod are slidably mounted, and a blocking mechanism and an ejection mechanism are provided on the ejection box.

[0005] Furthermore, the blocking mechanism includes an upper blocking block slidably mounted on the ejection box, upper and lower pressure blocks are fixedly mounted on the upper blocking block, the upper and lower pressure blocks are slidably mounted with the ejection box, a downward pressure slide column is arranged below the ejection box, a lower blocking block is slidably mounted on the ejection box, a downward pressure block is fixedly mounted on the lower blocking block, the lower pressure block is slidably mounted with the ejection box, a downward pressure spring is arranged between the upper blocking block and the downward pressure slide column, a downward pressure spring is arranged between the lower blocking block and the downward pressure slide column, switches are arranged on both the upper blocking block and the lower blocking block, and a switch is arranged on the inner wall of the ejection box.

[0006] Furthermore, the ejection mechanism includes a limit ring fixedly mounted on the ejection box, and three ejection electric cylinders are fixedly mounted on the ejection box.

[0007] The motor shafts to be tested are stacked into the feed box, located on the feed block and the feed box. The motor is rotated to drive the motor gear to rotate, thereby driving the large gear to rotate through the transmission belt, thereby driving the rotating block to rotate, thereby driving the inner telescopic rod to slide in the feed block, and driving the feed block to slide up and down. When the feed block rises, just one motor shaft slides out and enters the ejection box. The feed block descends to block the next motor shaft, and only one motor shaft is ejected at a time.

[0008] The lower blocking block slides downward, and then the next motor shaft enters the push box from the feed box and falls on the front end of the push electric cylinder at the bottom and contacts the switch arranged on the inner wall of the push box. At this time, the bottom push electric cylinder is controlled to extend, and the motor shaft is pushed out in the direction of the limit circle. After the motor shaft is pushed out, it is continuously transported forward by the conveying device.

When the motor shaft continues to move forward, the measuring roller will be lifted, and the position of the lifting frame will be detected by the distance sensor to obtain the diameter of the motor shaft. The motor shaft continues to move forward, and the length of the motor shaft is obtained by measuring the rotation time of the roller and the forward speed of the motor shaft, and then the motor shaft reaches the output device.

[0014] In the initial state, the baffle holds the flip plate, and the torsion spring is in an unstressed state. When the motor shaft is conveyed to the flip plate, if the display shows that the diameter of the motor shaft is unqualified, the discharge electric cylinder at the corresponding position of the motor shaft will be retracted, driving the baffle to retract. The flip plate rotates due to the gravity of the motor shaft, the torsion spring is twisted, and the unqualified motor shaft falls out. Then the torsion spring rebounds, driving the flip plate to reset, and then the discharge electric cylinder extends and resets, and the baffle is re-located under the flip plate.

[0015] The qualified motor shaft is located on the movable ball and is pushed forward by the next motor shaft to arrive on the discharge rack, completing the inspection.

[0031] like Figure 2-Figure 4 As shown, the ejection mechanism includes a limit ring 103 fixedly mounted on the ejection box 102 , and three ejection electric cylinders 104 are fixedly mounted on the ejection box 102 .

[0032] The motor shaft to be tested is stacked into the feed box 101, located on the feed block 111 and the feed box 101, and the rotating motor 105 rotates to drive the motor gear 106 to rotate, thereby driving the large gear 108 to rotate through the transmission belt 107, thereby driving the rotating block 109 to rotate, thereby driving the inner telescopic rod 110 to slide in the feed block 111, and driving the feed block 111 to slide up and down. When the feed block 111 rises, just one motor shaft slides out and enters the ejection box 102, and the feed block 111 descends to block the next motor shaft, and only one motor shaft is ejected at a time.

[0033] When the motor shaft enters the ejection box 102, it is blocked by the upper blocking block 112. At this time, the motor shaft triggers the switch 118 on the upper blocking block 112, so that the ejection electric cylinder 104 next to the upper blocking block 112 extends out, pushing the motor shaft in the direction of the limit ring 103. After the motor shaft is pushed out, its tail is located on the upper and lower pressing blocks 113, which press the upper and lower pressing blocks 113 down, and the lower pressing spring 116 is compressed, and the upper blocking block 112 slides downward.

After the motor shaft is pushed out, its tail is located on the lower pressing block 115, which presses down the lower pressing block 115 and compresses the lower pressing spring 116.

At this time, the lowest pushing electric cylinder 104 is controlled to extend out and push the motor shaft in the direction of the limit ring 103.

[0035] like Figure 5-Figure 7 As shown, the toggle mechanism includes a toggle motor 207 fixedly mounted on the detection frame 201, a toggle gear 208 fixedly mounted on the motor shaft of the toggle motor 207, a toggle toothed belt 209 wound around the detection frame 201, the toggle gear 208 meshes with the toggle toothed belt 209, and three rotating gear rings 212 are rotatably mounted on the detection frame 201, and the rotating gear rings 212 mesh with the toggle toothed belt 209.

[0037] The rotation of the motor gear 106 will drive the transmission gear 202 to rotate, thereby driving the driving wheel 203 to rotate, thereby driving the conveyor belt 205 to rotate, and the conveyor belt 205 drives the ball 206 to rotate, thereby conveying the motor shaft toward the opening frame 301 through the ball 206. When the ball 206 contacts the lifting block 215, the lifting block 215 will be lifted, thereby driving the lifting frame 213 to rise, so as to detect motor shafts of different diameters. When the motor shaft continues to move forward, the measuring roller 214 will be lifted, and the position of the lifting frame 213 will be detected by the distance sensor 211 to obtain the diameter of the motor shaft. The motor shaft continues to move forward, and the length of the motor shaft is obtained by measuring the rotation time of the roller 214 and the forward speed of the motor shaft, and then the motor shaft reaches the output device.

[0038] like Figure 8 , Fig. 9As shown, the output device includes a discharge rack 302 fixedly mounted on an opening rack 301, three display screens 303 are arranged on the opening rack 301, the data reaching the motor shaft on the output device are summarized in the display screen 303, a flip plate 304 is rotatably mounted on the opening rack 301, a plurality of movable balls 305 are rotatably mounted on the flip plate 304, a torsion spring 306 is arranged between the flip plate 304 and the opening rack 301, three discharge electric cylinders 307 are fixedly mounted on the opening rack 301, and a baffle 308 is fixedly mounted on the top of the discharge electric cylinder 307.

[0039] In the initial state, the baffle 308 holds the flip plate 304, and the torsion spring 306 is in an unstressed state. When the motor shaft is conveyed to the flip plate 304, if the display screen 303 shows that the diameter of the motor shaft is unqualified, the discharge cylinder 307 at the corresponding position of the motor shaft is retracted, driving the baffle 308 to retract. The flip plate 304 rotates due to the gravity of the motor shaft, the torsion spring 306 is twisted, and the unqualified motor shaft falls out. Then the torsion spring 306 rebounds, driving the flip plate 304 to reset. Then the discharge cylinder 307 extends and resets, and the baffle 308 is re-located under the flip plate 304.

[0040] The qualified motor shaft is located on the movable ball 305, and is pushed forward by the next motor shaft to arrive on the discharge rack 302, completing the inspection.

[0041] The working principle of a batch motor shaft diameter detection device disclosed in the present invention is: the motor shafts to be detected are stacked into a feed box 101, located on a feed block 111 and the feed box 101, the rotating motor 105 rotates to drive the motor gear 106 to rotate, thereby driving the large gear 108 to rotate through the transmission belt 107, thereby driving the rotating block 109 to rotate, thereby driving the inner telescopic rod 110 to slide in the feed block 111, driving the feed block 111 to slide up and down, when the feed block 111 rises, just one motor shaft slides out and enters the ejection box 102, the feed block 111 descends to block the next motor shaft, and only one motor shaft is ejected each time. When the motor shaft enters the ejection box 102, it is blocked by the upper blocking block 112. At this time, the motor shaft triggers the switch 118 on the upper blocking block 112, so that the ejection electric cylinder 104 next to the upper blocking block 112 extends out, pushing the motor shaft in the direction of the limit ring 103. After the motor shaft is pushed out, its tail is located on the upper and lower pressing blocks 113, which press the upper and lower pressing blocks 113 down, and the lower pressing spring 116 is compressed, and the upper blocking block 112 slides downward. At this time, the next motor shaft just enters the ejection box 102 from the feed box 101, and the next motor shaft is blocked by the lower blocking block 114, triggering the switch 118 on the lower blocking block 114, so that the next The pushing electric cylinder 104 next to the blocking block 114 extends out and pushes the motor shaft in the direction of the limit ring 103. After the motor shaft is pushed out, its tail is located on the lower pressing block 115, which presses down the lower pressing block 115 and compresses the lower pressing spring 116. The lower blocking block 114 slides downward, and then the next motor shaft enters the pushing box 102 from the feed box 101 and falls on the front end of the lowest pushing electric cylinder 104 and contacts the switch 118 provided on the inner wall of the pushing box 102. At this time, the lowest pushing electric cylinder 104 is controlled to extend out and push the motor shaft in the direction of the limit ring 103. After the motor shaft is pushed out, it continues to be transported forward by the conveying device. The rotation of the motor gear 106 will drive the transmission gear 202 to rotate, thereby driving the driving wheel 203 to rotate, thereby driving the conveyor belt 205 to rotate, and the conveyor belt 205 drives the ball bearing 206 to rotate, thereby conveying the motor shaft toward the opening frame 301 through the ball bearing 206. When the ball bearing 206 contacts the lifting block 215, the lifting block 215 will be lifted, thereby driving the lifting frame 213 to rise, so as to detect motor shafts of different diameters. When the motor shaft continues to move forward, the measuring roller 214 will be lifted, and the position of the lifting frame 213 will be detected by the distance sensor 211, so as to obtain the diameter of the motor shaft. The motor shaft continues to move forward, and the length of the motor shaft is obtained by measuring the rotation time of the roller 214 and the forward speed of the motor shaft, and then the motor shaft arrives at the output device. The qualified motor shaft is located on the movable ball bearing 305, and is pushed forward by the next motor shaft to arrive at the discharging frame 302 to complete the detection.
