Description

Technical Field

[0001] The present invention relates to the technical field of angle sensors, and in particular to an angle sensor based on the Internet of Things. Background Art

[0002] Angle sensors are mainly used to measure and monitor parameters such as the position, motion state and posture angle of equipment. After the shaft of the angle sensor is connected to the equipment component, when the equipment component rotates, the shaft of the angle sensor can be driven to rotate. The angle sensor can detect the rotation angle of its shaft to understand the rotation angle of the equipment component. When the angle sensor detects angle changes, in order to understand the angle parameters in real time, a wireless transceiver structure is sometimes configured on the angle sensor. After the wireless transceiver structure is connected to the network, the angle information can be transmitted to the controller in real time through the network to achieve Internet of Things connection control. When the existing Internet of Things-based angle sensors are used, in order to avoid the rotation of the angle sensor and affect the detection effect, screws are usually used to fix the angle sensor on the equipment housing. Although it has a good fixing effect, when it is fixed by screws, it is more troublesome to subsequently inspect and disassemble the angle sensor. If the screws are rusted, it is more troublesome to unscrew the screws, and it is more inconvenient to disassemble the angle sensor. At the same time, when using a test device to test the accuracy of the angle sensor, it is fixed by screws. Due to the need for frequent disassembly, the test is more troublesome.

Thus, the sensor body 100 is fixed on the mounting seat 110 by the fixing frame 120 and the locking tube 130. When the sensor body 100 needs to be replaced or repaired, the locking block 141 can be rotated to make the locking block 141 correspond to the locking slot 121. At this time, the sensor body 100 can be moved upward out of the mounting seat 110, so that the locking block 141 passes through the locking slot 121, so that the sensor body 100 can be quickly removed.

The position of the mounting seat 110 and the sensor body 100 is limited by the insertion rod. Then, the sliding plate 213 can be used through the electric telescopic rod 215 to drive the plurality of transmission cylinders 214 to move downward, so that the transmission cylinder 214 is sleeved on the corresponding axis of the sensor body 100.

After the sensor body 100 is placed on the placement seat 212, the power lines can be connected to the corresponding sensor body 100 to supply power to the sensor body 100.

[0025] like Figure 5-10As shown, in this embodiment, the inner side surface of the shell 210 corresponds to the sliding frame 220 and is slidably connected to the limit frame 230, the bottom of the side surface of the limit frame 230 is in contact with the side surface of the support rod 217, and the side surface of the sliding frame 220 is fixedly connected to three springs 222 fixedly connected to the inner side surface of the shell 210, and the spring 222 passes through the inside of the limit frame 230, and both sides of the top surface of the limit frame 230 are fixedly connected to L-shaped frames 231, and the inner side surface of the top of the L-shaped frame 231 is slidably connected to a sliding block 232, and the top surface of the shell 210 corresponds to the L-shaped frame 231. Rotatably connected to two adjusting shafts 240, the bottom end of the adjusting shaft 240 is fixedly connected to the limit rod 241, and the bottom surface of the limit rod 241 is The side is rotatably connected to the top surface of the adjacent sliding block 232 through an axis rod, the top surface of the shell 210 is fixedly connected to a connecting box 300, the side of the adjusting shaft 240 is rotatably connected to the inner side of the connecting box 300, the inner side of the connecting box 300 is rotatably connected to an adjusting rod 320, the side of the adjusting rod 320 corresponds to two adjusting shafts 240 fixedly sleeved with two worm gears 321, the side of the adjusting shaft 240 is fixedly sleeved with a worm wheel 242 meshing with the adjacent worm gear 321, the top surface of the connecting box 300 corresponds to an adjusting shaft 240 fixedly connected to a scale ring 310, an indicating block 330 is arranged inside the scale ring 310, and the bottom surface of the indicating block 330 is fixedly connected to the top of an adjusting shaft 240.

Under the action of the spring 1 222, the sliding frame 220 can be close to the limiting frame 230, so that the support rod 1 217 is abutted against the limiting frame 230, so that the rotation range of the support rod 1 217 can be limited by the limiting frame 230, and then the rotation angle of the transmission shaft 216 is limited, so that the angle of one rotation of the transmission shaft 216 is fixed, so that when the transmission shaft 216 drives the axis of the sensor body 100 to rotate a fixed angle through the transmission cylinder 214, the The angle detection data of the sensor body 100 is used to test the detection accuracy of the sensor body 100.

[0027] Embodiment 2

[0028] Based on the first embodiment, Figure 4 , Fig.11 , Fig.12 As shown, in this embodiment, the top surface of the housing 210 is located between the two adjustment shafts 240 and is fixedly connected to a fixing frame 250, the inner side surface of the fixing frame 250 is slidably connected to a connecting frame 260, the inner side surface of the bottom of the fixing frame 250 is rotatably connected to a linkage rod 270 extending to the inside of the connecting frame 260, the bottom end of the linkage rod 270 is fixedly connected to a support rod 271 rotatably connected to the top surface of the linkage plate 221, the side surface of the linkage rod 270 is located inside the connecting frame 260 and is fixedly sleeved with a connecting gear 272, and the inner bottom surface of the connecting frame 260 is rotatably connected There is a transmission rod 263, and the bottom of the side of the transmission rod 263 corresponds to the connecting gear 272 and is fixedly sleeved with a missing gear 1 266 and a missing gear 2 267. The missing gear 1 266 is located on the top of the missing gear 2 267. The top of the inner side of the connecting frame 260 is rotatably connected with a driving rod 261. The side of the driving rod 261 and the top of the side of the transmission rod 263 are both fixedly sleeved with a bevel gear 1 265, and the two bevel gears 1 265 are meshed for transmission. A motor 262 is arranged on the side of the connecting frame 260, and the output end of the motor 262 is transmission-connected to one end of the driving rod 261.

[0029] In a specific implementation, the motor 262 can drive the driving rod 261 to rotate, and the driving rod 261 can drive the transmission rod 263 to rotate through the bevel gear 1 265. The transmission rod 263 can drive the missing gear 1 266 and the missing gear 2 267 thereon to rotate. The teeth on the missing gear 1 266 and the missing gear 2 267 are staggered with each other, so that the teeth on both the missing gear 1 266 and the missing gear 2 267 will not be meshed with the connecting gear 272 at the same time. When the position of the limit frame 230 is adjusted by the adjusting rod 320 so that the rotation range of the support rod 1 217 is greater than 180 degrees and less than 360 degrees, the transmission rod 263 can be driven by the motor 262 to rotate a certain angle so that the teeth on the missing gear 1 266 are meshed with the connecting gear 272. At this time, the missing gear 1 266 can toggle the connecting gear 272. When the gear 272 rotates, the connecting gear 272 can drive the linkage rod 270 to rotate. The linkage rod 270 can drive the linkage plate 221 to rotate through the support rod 271, thereby driving the support rod 1 217 to rotate through the linkage plate 221, so that the transmission shaft 216 rotates. When the support rod 271 drives the linkage plate 221 to rotate, the sliding frame 220 and the linkage plate 221 will first move away from the limit frame 230. After the support rod 271 rotates to a state perpendicular to the limit frame 230, the support rod 271 continues to rotate to move the sliding frame 220 and the linkage plate 221 close to the limit frame 230. After the missing gear 1 266 drives the connecting gear 272 to rotate 180 degrees, the teeth on the missing gear 1 266 will disengage from the connecting gear 272. At this time, under the action of the spring 1 222, the sliding frame 220 and the linkage plate 221 will move away from the limit frame 230. The sliding frame 220 and the linkage plate 221 can be used to continue to move toward the limit frame 230, so that the support rod 1 217 continues to rotate, and the support rod 1 217 and the support rod 271 are in contact with the limit frame 230 again, and the limit frame 230 will block the support rod 1 217 and the support rod 271 again, and the rotation of the transmission shaft 216 is completed, so that the support rod 1 217 and the transmission shaft 216 can rotate a fixed angle at one time, and the transmission shaft 216 can drive the axis of the sensor body 100 to rotate through the transmission cylinder 214, so that the axis of the sensor body 100 rotates a fixed angle, and then compare the detection data of the sensor body 100 to determine the accuracy of the rotation angle detection of the sensor body 100, and there is no need to accurately control the rotation angle of the output shaft of the motor 262 to avoid the motor 262 The influence of the output shaft rotation angle on the test, at the same time, there is no need to set a scale plate to detect the shaft rotation angle of the sensor body 100, so there is no need to manually read the rotation angle on the scale plate, which is conducive to the rapid testing of the sensor body 100. When the position of the limit frame 230 is adjusted by adjusting the rod 320 so that the rotation range of the support rod 217 is greater than ninety degrees and less than one hundred and eighty degrees, the motor 262 can drive the transmission rod 263 to rotate a certain angle so that the teeth on the missing gear 267 are engaged with the connecting gear 272, and the missing gear 267 can drive the connecting gear 272 to rotate ninety degrees, so that the support rod 217 can smoothly pass through the position perpendicular to the limit frame 230, and then under the action of the spring 1 222, the linkage plate 221 continues to move.The support rod 217 continues to rotate, so that the support rod 217, the transmission shaft 216, etc. rotate to a fixed angle.

[0030] like Fig.13 As shown, in this embodiment, a sliding box 280 is slidably connected to the inner side surface of the connecting frame 260, and the linkage rod 270 is located between the transmission rod 263 and the sliding box 280. The other end of the driving rod 261 is fixedly connected to a rectangular rod 264 that passes through the interior of the sliding box 280, and one end of the rectangular rod 264 is rotatably connected to the inner side surface of the connecting frame 260. The side of the sliding box 280 away from the linkage rod 270 is fixedly connected to two springs 4 281 fixedly connected to the inner side surface of the connecting frame 260. The top of the inner side surface of the sliding box 280 is rotatably connected to a rotating rod 1 282 that is slidably connected to the side surface of the rectangular rod 264. The bottom of the inner side surface of the sliding box 280 is rotatably connected to a rotating rod 283. The side surface of the rotating rod 1 282 and the top of the side surface of the rotating rod 2 283 are both fixedly sleeved with a bevel gear 284, and the two bevel gears 284 are meshed for transmission. The bottom of the side surface of the rotating rod 283 is fixedly sleeved with a transmission gear 285 corresponding to the connecting gear 272.

[0031] In a specific implementation, under the action of the spring four 281, the position of the sliding box 280 relative to the connecting frame 260 can be limited, and the rotating rod one 282 can slide on the rectangular rod 264. When the motor 262 drives the driving rod 261 to rotate, the driving rod 261 can drive the rectangular rod 264 to rotate, and the rectangular rod 264 can drive the rotating rod one 282 to rotate. The rotating rod one 282 can drive the rotating rod two 283 to rotate through the bevel gear two 284. When it is necessary to perform a durability test on the sensor body 100, the adjusting rod 320 can be rotated to move the limit frame 230 away from the linkage rod 270, so that the support rod one 217 and the support rod two 271 are both separated from the limit frame 230. At this time, the connecting frame 260 can slide in the fixed frame 250, and the connecting frame 260 can be Spring four 281 pushes the sliding box 280 to move, so that the transmission rod 263 drives the missing gear one 266 and the missing gear two 267 to move away from the transmission rod 263, and makes the transmission gear 285 on the rotating rod two 283 move close to the connecting gear 272. After the transmission gear 285 is engaged with the connecting gear 272, the driving rod 261 can be driven to rotate by the motor 262, and the driving rod 261 drives the rotating rod one 282 to rotate, so that the rotating rod two 283 rotates. The rotating rod two 283 can drive the continuous linkage rod 270 to rotate through the transmission gear 285 and the connecting gear 272, thereby continuously driving the linkage plate 221 and the transmission shaft 216 to rotate, and then continuously driving the axis of the sensor body 100 to rotate, and the sensor body 100 is subjected to a durability test.

[0032] like Figure 11-15As shown, in this embodiment, the side of the transmission rod 263 is located between the missing gear 1 266 and the bevel gear 1 265, and is rotatably connected to a positioning plate 269 fixedly connected to the inner side of the connecting frame 260; the side of the transmission rod 263 is located between the positioning plate 269 and the missing gear 1 266, and is fixedly sleeved with a missing gear 3 268; the side of the fixed frame 250 is fixedly connected to a connecting frame 254 corresponding to the positioning plate 269; the bottom surface of the connecting frame 254 is slidably connected to a gear rod 255 corresponding to the missing gear 3 268; the top surface of the gear rod 255 is fixedly connected to a positioning block 256 slidably connected to the inner side surface of the connecting frame 254; both sides of the positioning block 256 are fixedly connected to the inner side surface of the connecting frame 254 A spring three 257 is fixedly connected, and the inner top surface of the connecting frame 254 is located on both sides of the positioning block 256 and is fixedly connected to the limiting blocks 258. The inner bottom surface and the inner top surface of the fixed frame 250 are fixedly connected to two limiting plates 251. The side of the limiting plate 251 is slidably connected to the side of the connecting frame 260. The inner side surface of the limiting plate 251 is slidably connected with a stopper 252, and two adjacent stoppers 252 are in contact with each other. The inner side surface of the limiting plate 251 is fixedly connected with a spring two 253 fixedly connected to the side of the stopper 252. The top and bottom surfaces of the connecting frame 260 are fixedly connected with rounded blocks 290 corresponding to the stoppers 252, and the side of the rounded block 290 is in contact with the arc surface of the ends of the two adjacent stoppers 252.

[0033] During specific implementation, the limiting plate 251 can support the connecting frame 260, and the stopper 252 can slide in the limiting plate 251. The arc surface of the side wall of the rounded block 290 contacts the arc surface of one side of the stopper 252. Under the action of the second spring 253, the position of the stopper 252 can be limited, so that the rounded block 290 is prevented from moving to the side of the fixed frame 250 located at the motor 262 through the stopper 252, and the linkage rod 270 is rotatably arranged on the fixed frame 250, and the linkage rod 270 is located between the transmission rod 263 and the sliding box 280, so that the movement range and position of the connecting frame 260 can be limited. The positioning plate 269 can support and limit the transmission rod 263. The side of the connecting frame 260 is provided with an opening, and the connecting frame 254 and the gear rod 255 on the inner wall of the fixed frame 250 pass through the opening and are located inside the connecting frame 260. Under the action of the third spring 257, the position of the positioning block 256 can be limited. After the angle accuracy of the sensor body 100 is tested, before the durability of the sensor body 100 is tested, it is necessary to adjust the position of the connecting frame 260 and the sliding box 280. When the transmission gear 285 is meshed with the connecting gear 272, the driving rod 261 can be driven to rotate by the motor 262. The driving rod 261 can drive the transmission rod 263 to rotate through the bevel gear 1 265, so that the teeth on the missing gear 1 266 and the missing gear 2 267 are disengaged from the connecting gear 272, and then the teeth on the missing gear 3 268 are meshed with the gear rod 255. At this time, due to the limitation of the position of the connecting frame 260 by the stopper 252, the missing gear 3 268 will first move the gear rod 255, and the gear rod 255 can drive the positioning block 256 to move in the connecting frame 254. After the end of block 256 contacts the limit block 258 in the forward direction, the connecting frame 254 can prevent the positioning block 256 from continuing to move through the limit block 258, thereby preventing the gear rod 255 from continuing to move along the inner wall of the fixed frame 250. At this time, the missing gear three 268 will roll on the gear rod 255, so that the transmission rod 263 drives the connecting frame 260 to move in the fixed frame 250, and the connecting frame 260 can drive the rounded block 290 to move, so that the rounded block 290 squeezes the two blocks 252 and breaks through the corresponding two blocks 252, thereby driving the sliding box 280 to move toward the linkage rod 270 through the connecting frame 260, so that the missing gear one 266 and the missing gear two 267 are both away from the connecting gear 272, and the transmission gear 285 is close to the connecting gear 272, The connecting gear 272 is meshed with the transmission gear 285. At this time, the teeth on the missing gear three 268 will contact the teeth at the end of the gear rod 255, completing the adjustment of the position of the connecting frame 260 and the sliding box 280. Due to the change in the position of the transmission rod 263 and the missing gear three 268, the positioning block 256 will move in the opposite direction and disengage from the adjacent limit block 258, while the missing gear three 268 continues to rotate. When the teeth on the missing gear three 268 rotate to the position of the gear rod 255, after the missing gear three 268 rotates a certain angle, the teeth on the missing gear three 268 will disengage from the gear rod 255, so that the gear rod 255 will only move in a small range, and the gear rod 255 will not contact the corresponding limit block 258, so that the missing gear three 268 will not continue to roll on the gear rod 255, and the motor 262 continues to rotate. When the missing gear 3 268 and the transmission gear 285 are continuously driven to rotate, the connecting frame 260 will not continue to move, so that the durability test can be carried out smoothly. At this time, the arc surface on the other side of the stopper 252 is used to prevent the rounded block 290 from moving, and the transmission gear 285 is limited by the linkage rod 270, so as to limit the connecting frame 260. After the durability test of the sensor body 100 is completed, the driving rod 261 can be driven by the motor 262 to rotate in the opposite direction. At this time, the transmission rod 263 can drive the missing gear 3 268 to rotate in the opposite direction. After the teeth on the missing gear 3 268 rotate in the opposite direction to the end of the gear rod 255, the teeth at the end of the gear rod 255 can be abutted against the teeth of the missing gear 3 268 under the action of the spring 3 257, so that the missing gear 3 268 rotates in the opposite direction.The missing gear 3 268 can be smoothly re-engaged with the gear rod 255, and then the gear rod 255 can drive the positioning block 256 to move in the opposite direction. After the positioning block 256 contacts the limit block 258 in the forward direction, the connecting frame 254 will prevent the positioning block 256 and the gear rod 255 from continuing to move in the opposite direction through the limit block 258. Then the missing gear 3 268 can roll on the gear rod 255, so that the connecting frame 260 moves in the opposite direction to the original position, and the fillet block 290 moves in the opposite direction and breaks through the two adjacent blocks 252 again, so that the missing gear 1 266 and the missing gear 2 267 move to the side of the connecting gear 272, and then the connecting gear 272 drives the linkage rod 270 to rotate a fixed angle through the missing gear 1 266 or the missing gear 2 267 again, so as to test the accuracy of the sensor body 100 in detecting the rotation angle.
