Detailed implementation manners

[0043] In order to make the objectives, technical solutions and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments of the present invention. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0044] Refer to Figure 1 and Figure 2, an embodiment of the present invention provides an intelligent locator with dual encoders, which includes a base 1. An outer shell 2 is installed at the upper end of the base 1. The base 1 and the outer shell 2 are connected via a combination structure 3. A pair of supports 4 are fixedly connected inside the base 1. An encoder 5 is installed on the pair of supports 4. The output ends of the pair of encoders 5 are fixedly connected to a coupling 6. A pair of first gears 7 are rotatably connected to the support plate inside the base 1. One end of the coupling 6 is connected to one end of the first gear 7. An output shaft 8 is rotatably connected to the left side of the base 1. The output shaft 8 is located between the pair of first gears 7. A worm is installed on the output shaft 8. One end of the output shaft 8 passes through the support 4. The other end of the output shaft 8 is rotatably connected to the support plate inside the base 1. A second gear 9 is fixedly connected to the outer peripheral surface of the other end of the output shaft 8. The second gear 9 is meshed and connected to the pair of first gears 7. A shaft rod 13 is rotatably connected inside the base 1. A worm gear 10 is fixedly connected to the outer peripheral surface of the lower end of the shaft rod 13. The worm gear 10 is meshed with the worm. Support columns 11 are provided on both the base 1 and the support plate on the base 1. The upper end of the support column 11 is detachably connected to a top plate 12. A cam group 14 is also installed on the shaft rod 13. A side plate is fixedly connected to the support plate on the base 1. A proximity switch 15 is installed on the side plate. The proximity switch 15 corresponds to the cam group 14.

[0045] During operation, the rotating device is connected to the output shaft 8. When the rotating device rotates, the worm gear 10 and the worm in the intelligent locator are driven to rotate via the output shaft 8. The worm gear 10 and the worm drive the cam group 14 in the vertical direction to rotate 360 degrees in a plane. During the rotation, when the protruding part on the cam group 14 turns to the proximity switch 15, the proximity switch 15 will sense and act. When the concave part on the cam group 14 turns to the proximity switch 15, the proximity switch 15 will not act. The pair of encoders 5 and the output shaft 8 are linked to each other via the pair of first gears 7 and the second gear 9. During the rotation of the output shaft 8, an actual angle analog signal can be output. The pair of encoders 5 can achieve redundancy of precise positioning data, reduce fault shutdown, and the pair of encoders 5 can adopt different communication protocols to avoid equipment shutdown caused by a single communication network failure.

[0046] Refer to Figure 3-19 , the combination structure 3 includes a connection table 31, a connection cover 32, a first rectangular frame 33 and a second rectangular frame 36. The first rectangular frame 33 is fixedly connected to the side wall of the base 1. The second rectangular frame 36 is fixedly connected to the lower end outside the outer shell 2. The connection cover 32 is fixedly connected to the upper end outside the first rectangular frame 33. The connection table 31 is fixedly connected to the lower wall surface of the second rectangular frame 36. It further includes:

[0047] The upper connection module 34 on the lower wall surface of the connection platform 31. The upper connection module 34 includes a connection column 341 fixedly connected to the lower wall surface of the connection platform 31. A plurality of annularly distributed first position-limiting strips 342 are fixedly connected to the outer peripheral wall of the lower end of the connection column 341. The upper connection module 34 further includes a second anti-leakage sheet 343 sleeved on the outer peripheral wall of the connection column 341. The second anti-leakage sheet 343 is in close contact with one wall surface of the cylinder 352 close to the connection platform 31. The second anti-leakage sheet 343 is made of tpe material, which can prevent dust from flying into the cylinder 352 to ensure the normal use of the cylinder 352;

[0048] The lower connection module 35 on the inner bottom wall surface of the connection cover 32. The lower connection module 35 includes a first cylinder 351 and a second cylinder 352. The first cylinder 351 is fixedly connected to the connection cover 32. The second cylinder 352 is rotatably connected to the first cylinder 351. A circular hole three 3522 and a circular hole four 3524 are reserved in the middle of the second cylinder 352. The circular hole three 3522 and the circular hole four 3524 are connected to each other. The radial span of the circular hole four 3524 is smaller than the radial span of the circular hole three 3522. A second position-limiting port 3521 is reserved on the inner wall surface of the circular hole four 3524. The second position-limiting port 3521 and the first position-limiting strip 342 are engaged with each other. The vertical span of the first position-limiting strip 342 is smaller than or equal to the vertical span of the circular hole four 3524. A convex surface 3525 is reserved between the circular hole three 3522 and the circular hole four 3524. The vertical span of the second position-limiting port 3521 is smaller than the distance between the convex surface 3525 and the bottom wall surface of the circular hole three 3522. The convex surface 3525 is in contact with the wall surface of the first position-limiting strip 342.

[0049] A stop port 3512 is reserved on the inner wall surface of the first cylinder 351, and an external thread port 3511 is reserved on the outer peripheral surface of the first cylinder 351. A second stop strip 3523 is fixedly connected to the outer peripheral surface at the lower end of the second cylinder 352. The second stop strip 3523 is in contact connection with the wall surface of the first stop port 3512. The distance between the two side walls of the first stop port 3512 is greater than or equal to the distance between the two side walls of the second stop port 3521, and the distance between the two side walls of the first stop port 3512 is less than or equal to the interval between a pair of adjacent second stop ports 3521. When the second cylinder 352 is rotated, the second stop strip 3523 can rotate together with the second cylinder 352, and the second stop strip 3523 can move within the first stop port 3512. The distance between the two side walls of the first stop port 3512 restricts the moving distance of the second stop strip 3523, and then restricts the rotation angle of the second cylinder 352. Since the distance between the two side walls of the first stop port 3512 is greater than or equal to the distance between the two side walls of the second stop port 3521, and the distance between the two side walls of the first stop port 3512 is less than or equal to the interval between a pair of adjacent second stop ports 3521, when the second stop strip 3523 moves from one side of the first stop port 3512 to the other side, multiple second stop ports 3521 on the second cylinder 352 can all rotate to the area between a pair of adjacent first stop strips 342. Then each first stop strip 342 is staggered from the second stop port 3521, and the wall surface of each first stop strip 342 is in contact connection with the convex surface 3525. The second stop strip 3523 and the first stop port 3512 are adapted to each other, which can restrict the rotation angle of the second cylinder 352, so as to prevent the wall surface of the first stop strip 342 from not being able to contact the convex surface 3525 after rotating several times, enhancing the stability and convenience of use.

[0050] The connection platform 31 is installed in the lower connection module 35 on the connection cover 32 through the upper connection module 34. When the connection column 341 on the upper connection module 34 is inserted into the fourth round hole 3524 on the second cylinder 352, the first stop strip 342 on the peripheral wall of the connection column 341 is inserted into the second stop port 3521 on the inner wall surface of the fourth round hole 3524. When the connection column 341 is inserted to the lower end of the third round hole 3522, at this time, the first stop strip 342 just completely leaves the second stop port 3521, and the upper wall surface of the first stop strip 342 is flush with the convex surface 3525. At this time, rotate the second cylinder 352 to rotate the second stop port 3521 to a region farther from the first stop strip 342. At this time, the convex surface 3525 is in contact connection with the wall surface of the first stop strip 342. The convex surface 3525 realizes the vertical stop of the first stop strip 342, which can prevent the upper connection module 34 from separating from the lower connection module 35. The multiple first stop strips 342 are distributed to enhance the firmness of the assembly of the upper connection module 34. Compared with the structure fixedly connected by a tension screw rod, this structure does not need to use tools to unscrew the tension screw rod, and the disassembly is very convenient; at the same time, when disassembling, only need to rotate the second cylinder 352, making it effortless during disassembly.

[0051] Refer toFigure 5 , Figure 6 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , the lower connection module 35 further includes a change module 355. The change module 355 includes a circular hoop 3551, a linkage bar 3552, a rotating roller 3553, a rotating bar 3554, and a right-angle bar 3555. The circular hoop 3551 is clamped on the outer peripheral surface of the second cylinder 352. The rotating bar 3554 is rotatably connected to the end of the circular hoop 3551 farther from the second cylinder 352 via the rotating roller 3553. The right-angle bar 3555 is arranged at the other end of the rotating bar 3554. A stop bar 324 is fixedly connected to the outer peripheral surface of the connection cover 32. A restraint opening is reserved on the upper wall surface of the stop bar 324. The right-angle bar 3555 is embedded in the restraint opening.

[0052] A circular hole 321 and a circular hole 322 that penetrate through both ends are reserved on the wall surface of the connection cover 32. The first cylinder 351 is fixedly connected in the circular hole 321. A tension screw rod is screwed in the circular hole 322. The connection cover 32 is connected to the first rectangular frame 33 via the tension screw rod. A strip-shaped opening 323 that penetrates through the front and back is reserved on the side wall of the connection cover 32. The linkage bar 3552 is movably arranged in the strip-shaped opening 323. A pair of anti-leakage sheets 325 are also arranged in the strip-shaped opening 323. The pair of anti-leakage sheets 325 are arranged symmetrically on the left and right side walls of the linkage bar 3552.

[0053] During operation, when the rotating bar 3554 is pulled, the second cylinder 352 can be driven to rotate in the first cylinder 351. When the second cylinder 352 cannot rotate, at this time, when the rotating bar 3554 is rotated around the rotating roller 3553, the right-angle bar 3555 can be embedded into the restraint opening on the connection cover 32, and then the purpose of restricting the second cylinder 352 can be achieved, so as to prevent the second cylinder 352 from rotating during work and ensure the stability of the second cylinder 352. The anti-leakage sheet 325 is made of tpe material. When the linkage bar 3552 moves in the strip-shaped opening 323, both of the pair of anti-leakage sheets 325 can closely adhere to the gap between the linkage bar 3552 and the strip-shaped opening 323, thereby preventing dust and moisture from entering the combined structure 3 and extending the application cycle of the combined structure 3.

[0054] Refer to Figure 6 and Figure 17 , the lower connection module 35 further includes a fastening cylinder 354 and an internal thread 3541 arranged on the inner peripheral surface of the fastening cylinder 354. The fastening cylinder 354 is clamped on the outer peripheral surface of the second cylinder 352, and the outer peripheral surface of the fastening cylinder 354 is in contact connection with the end of the stop bar 3523 farther from the lower end of the first cylinder 351. The fastening cylinder 354 is screwed to the upper end of the first cylinder 351 via the internal thread 3541 and the external thread 3511.

[0055] Since the fastening cylinder 354 is threadedly connected to the external thread port 3511 through the internal thread port 3541 at the upper end of the first cylinder 351, the fastening cylinder 354 can be fixed to the first cylinder 351. Since the outer peripheral surface of the fastening cylinder 354 is in contact with the farther end of the second positioning strip 3523 from the lower end of the first cylinder 351, the fastening cylinder 354 can vertically position the second cylinder 352 through the second positioning strip 3523, thereby preventing the second cylinder 352 from separating from the first cylinder 351.

[0056] Refer to Figure 13 、 Figure 14 and Figure 15 , the lower connection module 35 further includes an upper jacking module 353. The upper jacking module 353 includes a frustum 3531 and a helical beryllium copper wire 3532. The frustum 3531 and the helical beryllium copper wire 3532 are arranged in the third round hole 3522. The lower wall surface of the connection column 341 is closely attached to the upper wall surface of the frustum 3531.

[0057] The connection column 341 is inserted into the third round hole 3522 and will initially press on the upper wall surface of the frustum 3531. At this time, the first positioning strip 342 just completely leaves the second positioning port 3521, and the upper wall surface of the first positioning strip 342 is flush with the convex surface 3525. The connection column 341 then extends further inward and will compress the helical beryllium copper wire 3532 by pressing on the frustum 3531. At this time, the upper wall surface of the first positioning strip 342 separates from the convex surface 3525. Then, rotate the second cylinder 352. Since there is no obstructive effect between the first positioning strip 342 and the convex surface 3525, the second cylinder 352 can be easily rotated; after the second cylinder 352 is rotated by a certain angle, the force generated by the change in the shape of the helical beryllium copper wire 3532 can automatically move the first positioning strip 342 to the area in contact with the convex surface 3525, which is convenient to operate.

[0058] When installing the lower connection module 35, first fix the first cylinder 351 in the first round hole 321 on the wall surface of the connection cover 32, then hoop the second cylinder 352 into the first cylinder 351 so that the second positioning strip 3523 faces one end of the first positioning port 3512, then hoop the fastening cylinder 354 on the outer peripheral surface of the second cylinder 352, then threadedly connect the fastening cylinder 354 to the first cylinder 351, and then hoop the change module 355 on the outer peripheral surface of the second cylinder 352.

[0059] When the upper connecting module 34 and the lower connecting module 35 are connected, while the connecting column 341 on the upper connecting module 34 is embedded in the circular hole 4 3524 on the cylinder 2 352, the stop strip 1 342 on the peripheral wall of the connecting column 341 is embedded in the stop opening 2 3521 on the inner wall of the circular hole 4 3524. The connecting column 341 is embedded in the circular hole 3522 and begins to press on the truncated cone 3531. At this moment, the stop strip 1 342 just completely leaves the stop opening 2 3521, and the upper wall surface of the stop strip 1 342 is flush with the convex surface 3525. The connecting column 341 then extends inward and presses the spiral beryllium copper wire 3532 through the truncated cone 3531 to compress it. At this moment, the wall surface of the stop strip 1 342 is separated from the convex surface 3525, and the cylinder 2 35 is rotated through the variable module 355. 2. When the stop bar 3523 is moved from one side of the stop opening 3512 to the other side, the multiple stop openings 3521 on the cylinder 352 can rotate to the area between a pair of adjacent stop bars 342. The force generated by the shape change of the spiral beryllium copper wire 3532 can automatically move the stop bar 342 to the area in contact with the convex surface 3525. At this moment, each stop bar 342 is staggered from the stop opening 3521, and the wall surface of each stop bar 342 is in contact with the convex surface 3525. The convex surface 3525 achieves the purpose of vertically stopping the stop bar 342, which can prevent the upper connecting module 34 from separating from the lower connecting module 35. Then, the right-angle bar 3555 on the variable module 355 is embedded in the constraint opening to tighten the cylinder 352.

[0060] Reference Figure 3 and Figure 21 The combined structure 3 further includes a linkage module 37, which includes a sleeve 372 screwed on the outer circumference of the connecting cover 32 and a linkage bar 371 fixedly connected to one end of the linkage bar 3552. The upper end of the linkage bar 3552 is fixedly connected to the lower wall of the sleeve 372, and the outer circumference of the sleeve 372 is fixedly connected to a protruding bar 373. When the combined structure 3 is disassembled or tightened, it is only necessary to bend the protruding bar 373 to drive the sleeve 372 to rotate. The sleeve 372 drives multiple linkage bars 3552 to act together through the linkage bar 371, so as to quickly disassemble and tighten the combined structure 3, and then quickly disassemble and tighten the base 1 and the shell 2, so as to repair the intelligent locator.

[0061] Working principle: During operation, the rotating device is connected to the output shaft 8. When the rotating device rotates, the worm wheel 10 and the worm in the intelligent positioning instrument are driven to rotate via the output shaft 8. The worm wheel 10 and the worm drive the vertical cam group 14 to rotate 360 ​​degrees in the plane. During the rotation, when the raised part on the cam group 14 turns to the proximity switch 15, the proximity switch 15 will sense the action. When the recessed part on the cam group 14 turns to the proximity switch 15, the proximity switch 15 will not act. A pair of encoders 5 and the output shaft 8 are linked to each other via a pair of gears 1 7 and gear 2 9. During the rotation of the output shaft 8, an actual angle analog signal can be output. A pair of encoders 5 can realize the redundancy of precise positioning data and reduce fault shutdown. In addition, a pair of encoders 5 can use different communication protocols to avoid equipment shutdown caused by a single communication network failure.

[0062] The connection platform 31 is installed in the lower connection module 35 on the connection cover 32 via the upper connection module 34. When the connection column 341 on the upper connection module 34 is embedded in the round hole 3524 on the cylinder 352, the stop bar 1 342 on the peripheral wall of the connection column 341 is embedded in the stop opening 2 3521 on the inner wall of the round hole 3524. When the connection column 341 is embedded in the lower end of the round hole 3522, the stop bar 1 342 is just completely out of the stop opening 3521. The second stopper 3521 leaves, and the upper wall of the stopper 342 is flush with the convex surface 3525. At this time, the protruding strip 373 is bent to drive the sleeve 372 to rotate. The sleeve 372 drives multiple linkage strips 1 3552 to act together through the linkage strip 2 371. The linkage strip 1 3552 drives the hoop 3551 to rotate. The hoop 3551 drives the rotating cylinder 2 352 to rotate the stopper 2 3521 to an area farther from the stopper 342. At this time, the convex surface 3525 is aligned with the The wall surfaces of the stop strip 1 342 are in contact and connected, and the convex surface 3525 realizes the vertical stop of the stop strip 1 342, which can prevent the upper connecting module 34 from being separated from the lower connecting module 35, thereby achieving rapid assembly between the upper connecting module 34 and the lower connecting module 35, and then achieving rapid assembly between the base 1 and the shell 2. When the intelligent locator needs to be disassembled, the reverse bending of the protrusion 373 can drive the cylinder 2 352 to rotate in the opposite direction, and then the stop strip 1 342 is rotated to the stop opening 2 3521. Under the cooperation of the force generated by the change in the shape of the spiral beryllium copper wire 3532, the connecting column 341 is quickly withdrawn from the cylinder 2 352, and then the base 1 and the shell 2 are quickly disassembled, so as to inspect and maintain the intelligent locator. Compared with the structure fixed with a tensioning screw, this structure does not require the use of tools to unscrew the tensioning screw, and the disassembly is very convenient; at the same time, the disassembly is effortless.
