Description

Technical Field

[0001] This invention relates to the field of testing platforms, and more specifically to an encoder-based turntable testing platform. Background Technology

[0002] As the name suggests, a testing platform is a professional platform used to conduct adaptability tests on products during the product manufacturing process. It is commonly seen in production workshops. By rotating a turntable, corresponding factory tests are performed on the products that enter the turntable one by one to ensure the quality of the products leaving the factory. At the same time, the encoder settings can ensure the progress and accuracy of the turntable rotation.

[0003] A Chinese patent publication number, CN116639531A, discloses a turntable rotation control method and control system based on an encoder. The method includes: equipment installation: installing a turntable and a servo motor with an encoder; setting two levers on the turntable; initial debugging: taking a point on the edge of the turntable as the mechanical zero point, rotating the mechanical zero point to the top or bottom of the turntable, reading the encoder reading as A0, and recording the turntable angle as β0 = 0 degrees; rotation control: before the turntable rotates, setting the target angle as βtag degrees, recording the current angle of the turntable as βori degrees, and recording the current encoder reading as Aori; first calculating the positioning value M; if βori ≤ βtag, calculating the encoder target reading Atag = M; if βori > βtag, calculating the encoder target reading Atag = M + 180; starting the control servo motor to make the encoder reading reach Atag. This invention enables more precise control of the turntable rotation angle.

[0004] For example, Chinese Patent Publication No. CN208921158U discloses a rotary testing platform and apparatus, relating to the field of testing fixtures. This rotary testing platform includes a drive assembly, a test mounting frame, and a test turntable. The test turntable carries a simulated object, and the test mounting frame is positioned close to the test turntable, connecting the simulated object to the part under test (DUT) and allowing the simulated object to be positioned relative to the DUT. The drive assembly includes a rotary drive component, and the test turntable is connected to the rotary drive component. The rotary drive component can drive the test turntable to rotate, causing the simulated object to move relative to the DUT. This rotary testing platform and apparatus can assist in testing the performance of the DUT under simulated actual working conditions, improving the authenticity and reliability of the test results.

[0005] The encoder-based turntable mentioned above still has the following problems when used: Most of the test platforms mentioned above exist individually, which makes the testing efficiency of products through the test platform low in the whole production process, thus affecting subsequent production and life.

[0006] Therefore, it is necessary to invent an encoder-based turntable testing platform to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide an encoder-based turntable testing platform to solve the problem mentioned in the background art that most of the aforementioned testing platforms exist individually, resulting in low testing efficiency for products throughout production and daily life, thus affecting subsequent production and daily life.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a turntable testing platform based on an encoder, comprising a support frame, wherein support legs are fixedly connected to the four corners of the bottom of the support frame, a servo motor of a drive assembly is fixedly mounted on the inner wall of the support frame via a connecting plate, the output shaft of the servo motor is drivenly connected to a drive shaft, and the drive shaft matches a pre-reserved fitting groove at the bottom of the central shaft, an encoder is fixedly connected to the outer wall of the servo motor, the encoder is connected to a controller via a connecting cable, the controller is fixedly mounted above the connecting plate, and a turntable is movably sleeved on the outer wall of the central shaft, and further comprising:

[0009] The first mounting component has sliding grooves on both sides of the central shaft. A vertical rod is fixedly connected to the bottom wall inside the sliding groove. A protrusion is slidably connected inside the sliding groove, and the protrusion is fixedly connected to the inner wall of a pre-reserved through hole one inside the turntable. The vertical rod is slidably connected to a pre-reserved through hole two inside the protrusion.

[0010] Drive component two: a motor is fixedly connected to the top wall of the central shaft, the output shaft of the motor is driven by drive shaft two, and the lower end of drive shaft two is rotatably connected to the bottom wall of the pre-reserved columnar cavity inside the central shaft through a bearing;

[0011] The second mounting component includes a gear fixedly sleeved on the outer wall of the second drive shaft. The gear meshes with a rack assembly. A locking block is fixedly connected to the end of the rack assembly. The end of the locking block matches a pre-reserved slot in the turntable. An extension rod is fixedly connected to the end of the locking block. The extension rod moves within a pre-reserved groove in the rack assembly. Both the rack assembly and the extension rod pass through a pre-reserved notch inside the vertical plate. The top and bottom walls of the vertical plate are fixedly connected to the top and bottom walls of the columnar cavity, facilitating the installation of the central shaft and the turntable.

[0012] Preferably, the cross-section of the drive shaft is convex, and the outer wall of the drive shaft is in contact with the inner wall of the fitting groove. During the rotation of the drive shaft driven by the servo motor, the central shaft rotates, which in turn drives the turntable to rotate for subsequent testing.

[0013] Preferably, the two symmetrically arranged protrusions and two symmetrically arranged slots reserved inside the turntable are located at the four positions of the through hole one inside the turntable, so that the installation of the turntable and the central shaft and the limiting operation required during installation are not affected.

[0014] Preferably, the top of the chute is open, which facilitates the addition or removal of turntables. This allows multiple turntables to be used simultaneously for testing smaller workpieces, improving overall testing efficiency.

[0015] Preferably, the rack assembly consists of two staggered racks, both of which are meshed with a gear. The ends of the two racks, which are far apart, are fixedly connected to locking blocks. The gear moves the linear position of the two meshing racks, thereby causing the locking blocks fixedly connected to the racks to change position.

[0016] Preferably, the card block is T-shaped, and the outer wall of the T-shaped card block is attached to and slidably connected to the inner wall of the T-shaped movable channel to ensure the stability of the card block's movement.

[0017] Preferably, the mating groove is formed inside the two racks of the rack assembly, and the two ends of the mating groove are through-holes. The inner wall of the mating groove is in contact with and slidably connected to the outer wall of the extension rod that is fixedly connected to the end of the locking block. The end of the extension rod away from the locking block that is fixedly connected to it is always located in the mating groove that matches the extension rod, thus ensuring the stability of the movement of the entire rack assembly.

[0018] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0019] 1. This invention drives the rotation of the gear fixedly sleeved on the outer wall of the drive shaft by starting the motor. The two racks in the rack assembly that mesh with the gear move towards each other, thereby driving the locking block fixedly connected to the end of the rack to move away from the slot reserved inside the turntable. This facilitates the up and down movement of the turntable to adjust its height position, making it easier for objects of different heights to enter the turntable and facilitating subsequent inspection work. At the same time, during the movement of the locking block, the movable connection between the extension rod and the mating groove makes the movement of the locking block more stable.

[0020] 2. When adjusting the two turntables up and down, the protrusions fixedly connected to the inner wall of the through hole inside the turntable slide on the outer wall of the upright fixedly connected inside the central shaft. This ensures that when the entire turntable is adjusted, the angle position will not shift except for the change in the height position of the turntable. This makes it easier to fix the turntable in the subsequent position and ensures the accuracy of the installation. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This invention provides, for example Figure 1-9 The illustrated encoder-based turntable testing platform includes a support frame 1. Support legs 2 are fixedly connected to the four corners of the bottom of the support frame 1. A servo motor 41 from a drive assembly 4 is fixedly mounted on the inner wall of the support frame 1 via a connecting plate 3. The output shaft of the servo motor 41 is driven by a drive shaft 42, which matches a pre-drilled fitting groove 43 at the bottom of the central shaft 8. An encoder 5 is fixedly connected to the outer wall of the servo motor 41. The encoder 5 is connected to a controller 7 via a connecting cable 6. The controller 7 is fixedly mounted above the connecting plate 3. A turntable 9 is movably fitted onto the outer wall of the central shaft 8. The platform also includes:

[0035] The mounting component 10 has sliding grooves 1001 on both sides of the central shaft 8. The bottom wall of the sliding groove 1001 is fixedly connected to the upright 1002. The sliding groove 1001 is slidably connected to the protrusion 1003, and the protrusion 1003 is fixedly connected to the inner wall of the through hole 91 reserved inside the turntable 9. The upright 1002 is slidably connected to the through hole 1004 reserved inside the protrusion 1003. This ensures that when the turntable 9 is installed with the central shaft 8, only the height position will change, and there will be no angular deviation, thus ensuring the accuracy of the installation of the turntable 9.

[0036] Drive assembly 2 11, a motor 1101 is fixedly connected to the top wall of the central shaft 8, the output shaft of the motor 1101 is driven by drive shaft 2 1102, the lower end of drive shaft 2 1102 is rotatably connected to the bottom wall of the pre-reserved columnar cavity 81 inside the central shaft 8 through a bearing, the rotation of drive shaft 2 1102 causes the rotation of gear 1201, thereby causing the two racks in rack assembly 1202 that are meshed with gear 1201 to move and move the locking block 1203;

[0037] The second mounting component 12 has a gear 1201 fixedly sleeved on the outer wall of the second drive shaft 1102. The gear 1201 meshes with the rack assembly 1202. A locking block 1203 is fixedly connected to the end of the rack assembly 1202. The end of the locking block 1203 matches the slot 1204 reserved in the turntable 9. An extension rod 1206 is fixedly connected to the end of the locking block 1203. The extension rod 1206 moves in the mating groove 1207 reserved in the rack assembly 1202. Both the rack assembly 1202 and the extension rod 1206 pass through the notch 1209 reserved inside the vertical plate 1208. The top and bottom walls of the vertical plate 1208 are fixedly connected to the top and bottom walls of the columnar cavity 81, which facilitates the installation of the central shaft 8 and the turntable 9.

[0038] The cross-section of drive shaft 42 is convex, and the outer wall of drive shaft 42 fits against the inner wall of fitting groove 43. During the rotation of drive shaft 42 driven by servo motor 41, the central shaft 8 is rotated, which in turn drives the turntable 9 to rotate for subsequent testing.

[0039] The two symmetrically arranged protrusions 1003 and two symmetrically arranged slots 1204 are located at the four positions of the through hole 91 inside the turntable 9, so that the installation of the turntable 9 and the central shaft 8 and the limiting operation required during installation are not affected.

[0040] The top of the slide 1001 is open, which makes it easy to add or remove turntables 9. This allows multiple turntables 9 to be used simultaneously for testing smaller workpieces, improving overall testing efficiency.

[0041] The rack assembly 1202 consists of two staggered racks, both of which mesh with the gear 1201. The ends of the two racks that are far apart are fixedly connected to the locking blocks 1203. The gear 1201 moves the two meshing racks in a straight line, thereby causing the locking blocks 1203 fixedly connected to the racks to change position.

[0042] The locking block 1203 is T-shaped, and the outer wall of the T-shaped locking block 1203 is attached to and slidably connected to the inner wall of the T-shaped movable channel 1205 to ensure the stability of the movement of the locking block 1203.

[0043] The mating groove 1207 is formed inside the two racks of the rack assembly 1202, and the two ends of the mating groove 1207 are through. The inner wall of the mating groove 1207 is in contact with and slidably connected to the outer wall of the extension rod 1206, which is fixedly connected to the end of the locking block 1203. The end of the extension rod 1206 away from the locking block 1203 is always located in the mating groove 1207 that matches the extension rod 1206, thus ensuring the stability of the movement of the entire rack assembly 1202.

[0044] Working Principle: When using an encoder-based turntable testing platform, the motor 1101 is first started, driving the drive shaft 1102 connected to the output shaft of the motor 1101 to rotate. This, in turn, drives the gear 1201, which is fixedly sleeved on the outer wall of the drive shaft 1102, to rotate synchronously. During the rotation of the gear 1201, the two staggered racks in the rack assembly 1202 that mesh with the two sides of the gear 1201 move synchronously. At this time, the two racks move towards each other, which drives the two symmetrically arranged locking blocks 1203, which are fixedly connected to the ends of the two racks, to move towards each other. The locking blocks 1203 move away from the slots 1204 reserved inside the turntable 9. At this time, the locking force between the turntable 9 and the central shaft 8 is lost, allowing the turntable 9 to move up and down easily. To facilitate the adjustment of the height position of the turntable 9, when adjusting the two turntables 9 up and down, the protrusion 1003 fixedly connected to the inner wall of the through hole 91 inside the turntable 9 slides on the outer wall of the upright 1002 fixedly connected inside the central shaft 8. This ensures that when the entire turntable 9 is adjusted, only the height position of the turntable 9 changes, and other angular positions will not shift. This makes it easier to fix the position of the turntable 9 in the future, thus ensuring the accuracy of the installation. The height adjustment of the turntable 9 also makes it easier for objects of different heights to enter the turntable 9 for subsequent testing. The rotation of the central shaft 8 and the turntable 9 fixedly installed on the outer ring of the central shaft 8 is driven by the servo motor 41 equipped with encoder 5, ensuring that the rotation of the turntable 9 is more precise and ensuring the accuracy of the subsequent test results.

[0045] During the movement of the locking block 1203, the "T"-shaped locking block 1203 moves within the "T"-shaped movable channel 1205 reserved inside the central shaft body 8, ensuring the stability of the movement of the locking block 1203. At the same time, the extension rod 1206, which is fixedly connected to the locking block 1203, moves with the corresponding overlapping groove 1207 during the movement of the locking block 1203, making the movement of the locking block 1203 more stable.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
