Description

Technical Field

[0001] This invention belongs to the field of speed reducer production and testing technology, and specifically relates to a positioning and testing device for speed reducer production. Background Technology

[0002] During the production and assembly of speed reducers, the coaxiality of the drive motor and the speed reducer housing, as well as the flatness of the connecting hole diameter, directly determine the operational stability of the equipment. Traditional assembly equipment relies on simple tooling (such as locating pins and calipers) to achieve rough alignment of workpieces, which cannot accurately detect the flatness of the inner wall of the hole diameter. When there are local protrusions or burrs in the hole diameter, stress concentration is easily generated after the bolts are tightened, causing the vibration frequency of the equipment to exceed the standard during operation.

[0003] Existing equipment can only use a simple positioning mechanism to position the reducer and drive motor. After installation, the excessive vibration frequency cannot be quickly detected, which is a problem that urgently needs to be solved by those in the field. Summary of the Invention

Detailed Implementation

[0033] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-15 The present invention provides a technical solution including an operating table 1 and a controller on one side of the operating table 1. The top of the operating table 1 is provided with two sets of electric slide rails 2. The two ends of the two sets of electric slide rails 2 are slidably connected with two sets of sliders 3. The top of each pair of adjacent sliders 3 is fixedly connected with a mounting plate 4. The top of each pair of mounting plates 4 is provided with a clamping assembly 5. The clamping assembly 5 includes a mounting block 501 hinged to the mounting plate 4. The top of the mounting block 501 is provided with two sets of electric telescopic rods 502. The bottom of each set of electric telescopic rods 502 is fixedly connected with a clamping block 503. The bottom of the clamping block 503 is provided with a vibration sensor 504. A drive motor 6 is provided inside one set of clamping assembly 5, and a reducer housing 7 is provided inside the other set of clamping assembly 5.

[0035] Two sets of clamping components 5 clamp and fix the drive motor 6 and the reducer housing 7 respectively. The mounting blocks 501 in the two sets of clamping components 5 rotate around the hinge axis, so that the two sets of mounting blocks 501 are respectively above the drive motor 6 and the reducer housing 7. Then, the electric telescopic rod 502 is activated by the operating table 1. The output end of the electric telescopic rod 502 extends and can push the clamping block 503 to move, thereby clamping and fixing the drive motor 6 and the reducer housing 7 respectively. The electric slide rail 2 is electrically connected to the controller. When the slider 3 in the electric slide rail 2 drives the mounting plate 4 to move, and the two sets of mounting plates 4 move in opposite directions, the two sets of mounting plates 4 can respectively drive the reducer housing 7 and the drive motor 6 to move simultaneously to the middle or both sides, so as to adjust the position of the reducer housing 7 and the drive motor 6.

[0036] A support frame 8 is provided above the operating table 1. Two sets of hydraulic cylinders 10 are installed on the top of the support frame 8. The output ends of the two sets of hydraulic cylinders 10 are connected to fixed plates 9. The two sets of fixed plates 9 are rotatably connected to positioning rods 11.

[0037] The hydraulic cylinder 10 can push the fixed plate 9 and the positioning rod 11 to move up and down, so as to adjust the position and height of the fixed plate 9 and the positioning rod 11.

[0038] The housing of the drive motor 6 is provided with four sets of first apertures 12, and the housing of the reducer housing 7 is provided with second apertures 13.

[0039] During the movement of the drive motor 6 and the reducer housing 7, the first aperture 12 of the drive motor 6 housing and the second aperture 13 of the reducer housing 7 housing can be slidably connected with the positioning rod 11.

[0040] An inflation assembly 14 is provided on the outside of the fixed plate 9. The inflation assembly 14 includes an air pump 1401 fixedly installed on one side of the fixed plate 9. The air outlet of the air pump 1401 is connected to one end of a central tube 1402. The other end of the central tube 1402 is rotatably connected to a three-way pipe 1403. One end of the three-way pipe 1403 and the outside of the central tube 1402 are fitted with a support sleeve 1404. The other two ends of the three-way pipe 1403 are respectively connected to a first pipe 1405 and a second pipe 1406. A positioning rod is also provided. An annular groove 1407 is provided on the outside of 11. Two sets of first fixing grooves 1408 are provided inside the annular groove 1407. An airbag 1409 is provided inside each of the two sets of first fixing grooves 1408. One set of airbags 1409 is connected to the first pipe 1405, and the other set of airbags 1409 is connected to the second pipe 1406. Four sets of second fixing grooves 1410 are provided on the outer surface of the annular groove 1407. One end of a tension spring 1411 is fixedly connected inside each of the four sets of second fixing grooves 1410.

[0041] The controller is electrically connected to the air pump 1401. The controller controls the air pump 1401 to start, generating compressed air. This air can be diverted through the central pipe 1402 and the three-way pipe 1403 to the first pipe 1405 and the second pipe 1406, and finally injected into the two sets of airbags 1409 in the annular groove 1407 at the positioning rod 11.

[0042] When the air pump 1401 deflates, the air in the airbag 1409 is also released, the airbag 1409 contracts, and the four sets of tension springs 1411 can pull the first connecting block 1502 and the second connecting block 1602 to reset respectively.

[0043] like Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, a flatness detection component 15 is provided on one side of the annular groove 1407. The flatness detection component 15 includes a first fixing block 1501 that is slidably connected to one of the first fixing grooves 1408. A first connecting block 1502 is fixedly connected to one end of the first fixing block 1501 located outside the first fixing groove 1408. Multiple sets of first placement grooves 1503 are opened on the outer surface of the side of the first connecting block 1502 away from the first fixing block 1501. A first telescopic rod 1504 is fixedly connected inside the first placement groove 1503. A connecting frame 1506 is connected to one end of the first telescopic rod 1504. A first return spring 1505 is connected between the connecting frame 1506 and the first telescopic rod 1504. A ball bearing 1507 is rotatably connected inside the connecting frame 1506. A pressure sensor 1508 is fixedly installed inside the ball bearing 1507.

[0044] When the airbag 1409 inside the first fixing groove 1408 is inflated, it can push the first fixing block 1501 to move along the first fixing groove 1408, so that the first connecting block 1502 fixedly connected to the first fixing block 1501 moves synchronously. After the ball 1507 at the first connecting block 1502 contacts the inner wall of the aperture, the flatness of the inner wall of the aperture is judged by the numerical feedback of the pressure sensor 1508.

[0045] A grinding component 16 is provided on the side of the annular groove 1407 away from the flatness detection component 15. The grinding component 16 includes a second fixing block 1601 that is slidably connected to another set of first fixing grooves 1408. A second connecting block 1602 is fixedly connected to one end of the second fixing block 1601 located outside the second fixing groove 1410. A grinding stone 1603 is provided on the outer surface of the side of the second connecting block 1602 away from the second fixing block 1601.

[0046] After the airbag 1409 inside the other set of first fixing grooves 1408 is inflated, it can push the second fixing block 1601 and the second connecting block 1602 to move, so that the polishing stone 1603 at the second connecting block 1602 contacts the inner wall of the aperture.

[0047] It should be noted that after the air pump 1401 is started, valves are installed at both the first pipe 1405 and the second pipe 1406. The interior of the orifice needs to be tested for flatness first. At this time, the valve on the first pipe 1405 opens, allowing airflow to enter the airbag 1409 at the flatness detection component 15 through the first pipe 1405. This allows the airbag 1409 to push the first connecting block 1502 and the ball bearing 1507 at the flatness detection component 15 into contact with the inner wall of the orifice. The flatness is then fed back by the pressure sensor 1508. If the flatness is partially... If the pressure value is too high, it indicates that there is a protrusion on the inner wall of the aperture. At this time, the controller first controls the air pump 1401 to release air, so that the first fixing block 1501 of the detection component retracts into the annular groove 1407 along with the air bag 1409. At this time, the valve at the first pipe 1405 is closed and the valve at the second pipe 1406 is opened. Then the air pump 1401 restarts to inflate, pushing the second fixing block 1601 in the other set of first fixing grooves 1408 to move outward, causing the second connecting block 1602 and the polishing stone 1603 to fit against the protruding area of ​​the inner wall of the aperture.

[0048] A dust cleaning component 17 is provided on the outside of the positioning rod 11. The dust cleaning component 17 includes a support block 1701 fixedly connected to both sides of the positioning rod 11. A limit rod 1702 is fixedly connected to one side of the support block 1701. A connecting sleeve 1703 is slidably connected to the outside of the limit rod 1702. The connecting sleeve 1703 is sleeved on the outside of the positioning rod 11. Brushes 1704 are provided on both the inner and outer surfaces of the connecting sleeve 1703. A first cylinder 1705 is installed on the outside of the positioning rod 11. The output end of the first cylinder 1705 is fixedly connected to one side of the connecting sleeve 1703.

[0049] The controller is electrically connected to the first cylinder 1705. When the first cylinder 1705 is started, it can push the connecting sleeve 1703 to move along the limit rod 1702. The limit rod 1702 plays a guiding role to ensure that the moving trajectory of the brush 1704 is stable. During the movement of the connecting sleeve 1703, the brush 1704 can clean the dust from the polishing stone 1603 and the inner wall of the hole.

[0050] like Figure 7 As shown, a dust removal assembly 18 is provided inside the positioning rod 11. The dust removal assembly 18 includes two sets of airbags 1409 with air outlet pipes 1801 fixedly connected to both sides. A one-way valve 1802 is provided outside the air outlet pipes 1801.

[0051] After polishing, when the airbag 1409 is opened to release air, the internal airflow is discharged through the air outlet pipe 1801. The one-way valve 1802 prevents backflow of airflow, forming a local airflow that blows the debris swept by the brush 1704 away from the inside of the aperture, further improving the cleaning effect.

[0052] Two sets of fixing plates 9 are respectively provided with rotating components 19 on one side near the reducer housing 7 and the drive motor 6. The rotating components 19 include a gear ring 1901 fixedly connected to the outer surface of the positioning rod 11, a rack 1902 meshing with one side of the gear ring 1901, a connecting rod 1903 fixedly connected to the fixing plate 9 below the rack 1902, a sliding sleeve 1904 slidably connected to the outside of the connecting rod 1903, and a third cylinder 1905 fixedly installed on the fixing plate 9 below the connecting rod 1903. The output end of the third cylinder 1905 is fixedly connected to the sliding sleeve 1904.

[0053] The controller is electrically connected to the third cylinder 1905, controlling the extension or retraction of the third cylinder 1905. This causes the sliding sleeve 1904 and the rack 1902 to move on the outer surface of the connecting rod 1903. The rack 1902 is meshed with the gear ring 1901. During the movement, the rack 1902 can drive the gear ring 1901 to rotate, so that the positioning rod 11 can rotate synchronously. This allows the grinding assembly 16 to perform rotary grinding on the inside of the hole. Afterward, the dust cleaning assembly 17 can also rotate and remove dust and debris from the inner wall of the hole.

[0054] Example 1

[0055] When positioning testing is required after the installation of the reducer housing 7 and the drive motor 6, the two sets of clamping components 5 clamp the drive motor 6 and the reducer housing 7 respectively. Then, the drive mechanism in the electric slide rail 2 is activated, causing the reducer housing 7 and the drive motor 6 to move synchronously. The first aperture 12 and the second aperture 13 at the reducer housing 7 and the drive motor 6 move simultaneously to the outside of the positioning rod 11. Then, the flatness detection component 15 performs flatness testing on the inner walls of the two apertures. The value detected by the pressure sensor 1508 reflects whether the two apertures are flat. If they are not flat, the apertures need to be processed by the grinding component 16, the dust cleaning component 17, and the dust removal component 18. Finally, the flatness of the apertures at the reducer housing 7 and the drive motor 6 is tested again to complete the installation of the reducer housing 7 and the drive motor 6.

[0056] First, the user sets the initial numerical parameters through the controller. The numerical parameters include the standard value range of the vibration frequency of the vibration sensor 504 as H, the standard value of the pressure sensor 1508 in contact with the inner walls of the two sets of apertures as F, and the initial standard input airflow value of the air pump 1401 as P.

[0057] When replenishment is needed, the air pump 1401 inputs airflow with an initial standard airflow value P for a time t, which enables the airbag 1409 to push the ball 1507 at the first connecting block 1502 to fit against the inner wall of the aperture, and the standard pressure value is F.

[0058] When the first aperture 12 and the second aperture 13 at the reducer housing 7 and the drive motor 6 pass through the outside of the positioning rod 11 at the same time, it means that the first aperture 12 and the second aperture 13 at the reducer housing 7 and the drive motor 6 are in a parallel state. If one of the first aperture 12 and the second aperture 13 at the reducer housing 7 and the drive motor 6 cannot pass through the outside of the positioning rod 11, the position of the part that cannot pass through needs to be adjusted.

[0059] At this time, the reducer housing 7 and the drive motor 6 are respectively located at the flatness detection component 15 on the outer surface of the positioning rod 11. At this time, the controller controls the air pump 1401 to start. The air pump 1401 inputs airflow with an initial standard airflow value P. The normal standard input time is t. The air pump 1401 generates compressed air. At this time, the valve at the first pipe 1405 is opened and the valve at the second pipe 1406 is closed. The air can be diverted to the first pipe 1405 through the central pipe 1402 and the three-way pipe 1403. The airflow then enters through the first pipe 1405 and can push the first connecting block 1502 and the first fixing block 1501 to move, so that the ball 1507 at the first connecting block 1502 fits against the inner wall of the two sets of apertures. The pressure value is detected by the pressure sensor 1508 at the ball 1507.

[0060] Case 1: If the actual input airflow value of P1 is equal to the standard value, the actual input time of t1 is equal to the normal standard input time t, and the actual pressure value of F1 is equal to the standard pressure value F, it indicates that the inner wall of the orifice is flat.

[0061] Scenario 2: If the actual input airflow value of P1 is equal to the standard value, and the actual input time of t1 is less than the normal standard input time t, and the actual pressure value of local F1 is greater than the standard pressure value F, then it indicates that there is a protrusion on the inner wall of the orifice, and the inner wall of the orifice needs to be polished.

[0062] Scenario 3: If the actual input airflow value of P1 equals the standard value, and the actual input time of t1 equals the normal standard input time t, and the actual pressure value of F1 is less than the standard pressure value F, then the actual input time of t1 can be increased first. If the actual pressure value of F1 is still less than the standard pressure value F, it can be determined that there is a leak at the pipe connection or that the airbag 1409 is damaged. In this case, it needs to be repaired. After the repair is completed, if the actual input airflow value of P1 equals the standard value, and the actual input time of t1 equals the normal standard input time t, and the actual pressure value of F1 is still less than the standard pressure value F, then the actual input time of t1 can be increased again. If the actual pressure value of F1 is greater than the standard pressure value F, it can be determined that there is a dent in the inner wall of the orifice. In this case, the parts can be recycled.

[0063] For scenario two: Air pump 1401 releases air, and flatness detection component 15 resets. At this time, the valve at the first pipe 1405 is closed, and the valve at the second pipe 1406 is opened. Subsequently, air pump 1401 restarts inflation, with the airflow value input according to the initial standard value P. This pushes the second fixing block 1601 in the other set of first fixing grooves 1408 to move outward, causing the second connecting block 1602 and polishing stone 1603 to conform to the protruding area of ​​the inner wall of the aperture. The controller controls the third component in the rotating assembly 19. When cylinder 1905 is activated, rack 1902 moves and drives gear ring 1901 and positioning rod 11 to rotate synchronously, so that grinding stone 1603 at second connecting block 1602 can contact and grind the inner wall of first aperture 12 and second aperture 13. At this time, control air pump 1401 to release air, so that grinding component 16 is reset. Then control air pump 1401 to pressurize. If the actual pressure value F1 is equal to the standard pressure value F, it means that the inner wall of the aperture has been restored to flatness after grinding.

[0064] It should be added that the standard airflow input value P is the air pressure value at which the airbag 1409 expands to just push the detection component or the polishing component 16 to fit against the inner wall of the aperture and generate a preset contact force, so that when polishing the protruding part, the airbag 1409 will not be over-compressed due to the input of the same standard airflow value.

[0065] Through the above steps, the flatness of the inner wall of the hole at the connection between the reducer housing 7 and the drive motor 6 can be detected.

[0066] Example 2

[0067] In this embodiment, based on the case of Embodiment 1, when the inner walls of the apertures at the connection points of the reducer housing 7 and the drive motor 6 are flat and without protrusions, the controller controls the hydraulic cylinder 10 to start, moving the fixing plate 9 and the positioning rod 11 upwards. Then, the reducer housing 7 and the drive motor 6 are moved synchronously via the electric slide rail 2, aligning the first aperture 12 with the second aperture 13 and connecting them with bolts. The controller then starts the drive motor 6. The vibration frequency of the reducer housing 7 and the drive motor 6 after installation can be detected by the vibration value of the vibration sensor 504. If the actual vibration frequency value range is greater than the standard vibration frequency value range H, it indicates that the actual vibration frequency is too high. At this time, it can be determined that a large amount of dust is generated during the grinding process of the inner wall of the aperture, resulting in loose bolt connections. In this case, the bolts are disassembled, and the hydraulic cylinder 10 is controlled to descend and position. Rod 11 activates the dust cleaning assembly 17. The first cylinder 1705 pushes the connecting sleeve 1703 to move repeatedly, removing residual debris from the inner wall of the aperture through the brush 1704. At the same time, the airbag 1409 is deflated, and the airflow from the outlet pipe 1801 blows away the fine burrs. After the burrs are removed, the reducer housing 7 and the drive motor 6 are connected again by bolts, and the drive motor 6 is started. If the actual vibration frequency value is still greater than the standard vibration frequency value range H, it can be determined that the bolt connection is loose. A spring anti-loosening washer is installed between the bolt and the nut. The elasticity of the washer compensates for the torque attenuation during dynamic operation to prevent the bolt from loosening. If the actual vibration frequency value is still greater than the standard vibration frequency value range H, the component itself can be inspected. If the vibration frequency is within the range H after replacing the defective component and reconnecting, it is determined that the component itself is defective.

[0068] By following the steps above, we can troubleshoot any abnormal vibration frequencies after installation of components with normal inner wall flatness.
