Description

Technical Field

[0001] This utility model relates to the field of training equipment technology, and more specifically, to a positioner structure with a slip ring for training. Background Technology

[0002] Existing positioners, as auxiliary equipment during machining, are suitable for positional changes during rotary welding or grinding to achieve ideal machining angles and positions. However, due to structural limitations, traditional positioners mostly connect cables to the fixture or machining equipment from the workstation. During machining, this can easily lead to cable tangling, breakage, poor signal contact, or air leakage, thus affecting normal production. Furthermore, after years of use, the cables age faster due to the constant turning of the knobs, making maintenance more complicated.

[0003] Because existing positioners have the aforementioned defects, it is necessary to design a positioner with slip rings to solve the problem of cable tangling and messing. Furthermore, the positioner with slip rings needs to be used as a practical training device to facilitate practical teaching and enable students to master its working principle. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art. Its structure is reasonably designed. By making the active rotating shaft and the driven rotating shaft the same axis, the electric slip ring and the pneumatic slip ring are coaxially integrated, which can ensure the synchronization of pneumatic and electrical transmission and solve the problem of cable and pneumatic circuit entanglement.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A training positioner structure with slip rings includes a base, bearing seats on both sides of the base, a driving rotating shaft rotatably connected to one of the bearing seats, a driven rotating shaft rotatably connected to the other bearing seat, a rotating platform located above the base and fixedly connected at both ends to the driving and driven rotating shafts respectively, a drive motor located on the base, and a synchronous belt transmission mechanism connecting the drive motor and the driving rotating shaft. The driving and driven rotating shafts are arranged horizontally along the same axis. One of the driving and driven rotating shafts is provided with an air slip ring, and the other of the driving and driven rotating shafts is provided with an electric slip ring.

[0006] By adopting the above technical solution, the air slip ring can be set on the driven rotating shaft, while the electric slip ring can be set on the driving rotating shaft; of course, their positions can also be interchanged. The drive motor can be a servo motor, whose rotation angle can be precisely controlled. The drive motor drives the synchronous belt transmission mechanism, which in turn drives the driving rotating shaft to rotate. Then, the rotating platform rotates, driving the driven rotating shaft to rotate. Since the driving and driven rotating shafts share the same axis, the electric and air slip rings are coaxially integrated, ensuring the synchronization of pneumatic and electrical transmission and solving the problem of cable and air circuit entanglement.

[0007] Preferably, the air slip ring includes an air slip ring stator and an air slip ring rotor that are internally connected. The air slip ring rotor is linked to a driven rotating shaft, and the driven rotating shaft is provided with an air outlet that communicates with the interior of the air slip ring rotor. The air slip ring stator is connected to an external air passage.

[0008] By adopting the above technical solution, when the rotating platform rotates, the driven rotating shaft drives the air slip ring rotor to rotate, while the air slip ring stator is connected to the external air passage for air supply. By setting an air outlet on the driven rotating shaft, air supply to the air passage is ensured while the external air passage pipe will not become entangled.

[0009] Preferably, the electric slip ring includes an electric slip ring stator and an electric slip ring rotor disposed in the electric slip ring stator, the electric slip ring rotor being connected to rotor wires, and the electric slip ring stator being connected to stator wires.

[0010] By adopting the above technical solution, the electric slip ring rotor is connected to the active rotating shaft, and a conductive ring connected to the rotor wire is set inside the electric slip ring rotor. The electric slip ring stator includes brush filaments, one end of which is connected to the stator wire and the other end of which abuts against the conductive ring. In this way, the problem of cable tangling can be avoided.

[0011] Preferably, a sensing element is fixed on the driven rotating shaft or air slip ring rotor, and an end cover plate is fixedly installed on the bearing seat connected to the driven rotating shaft. The end cover plate is located on one side of the sensing element, and multiple sensors at angles to each other are installed on the end cover plate.

[0012] By adopting the above technical solution, the sensor can be specifically set as a proximity sensor. Since the end cover plate is fixed, the sensing element moves closer to different proximity sensors as the driven rotating shaft rotates, thereby realizing the detection of the rotation origin and rotation angle of the rotating platform.

[0013] Preferably, the rotating platform is provided with a processing device, a positioning fixture and a material placement mechanism. The material placement mechanism includes a mounting plate, a clamping cylinder on the mounting plate, a material receiving plate above the clamping cylinder, and a clamping block connected to the clamping cylinder and capable of clamping the material in the material receiving plate.

[0014] By adopting the above technical solution, the processing device can be a welding gun or a grinding head to realize welding or grinding operations, which is convenient for students to carry out on-site training. The positioning fixture is used to position the material, and the material to be processed is placed in the material receiving plate. The clamping cylinder drives the clamping block to clamp and position the material in the material receiving plate.

[0015] Preferably, the processing device is located on the rotating platform on one side of the electric slip ring, and the clamping cylinder is located on the rotating platform on one side of the air slip ring.

[0016] By adopting the above technical solution, this configuration facilitates the connection of cables to the processing device and the connection of the air passage to the clamping cylinder, resulting in a more reasonable structural layout.

[0017] Preferably, the synchronous belt transmission mechanism includes a driving wheel connected to a drive motor, a driven wheel connected to a driving shaft, and a synchronous belt connecting the driving wheel and the driven wheel, with a protective cover provided on the outside of the synchronous belt transmission mechanism.

[0018] By adopting the above technical solution and setting up a protective cover, the synchronous belt transmission mechanism can be well protected, and the safety hazards caused by accidental contact during student training can be reduced.

[0019] Preferably, at least one bearing housing is provided with a limit stop, and the base is provided with an electrical quick-connect interface.

[0020] By adopting the above technical solution, the limit block can be made of polyurethane buffer pad, which has a good buffering effect and can limit the rotation of the rotating platform. The setting of the electrical quick-connect interface facilitates the expansion and connection of other auxiliary devices.

[0021] The beneficial effects of this utility model are: This utility model has a reasonable structural design. By making the active and driven rotating shafts the same axis, the electric slip ring and the pneumatic slip ring are coaxially integrated, which can ensure the synchronization of pneumatic and electrical transmission, solve the problem of cable and air circuit entanglement, facilitate practical training, and enable students to master its working principle.

The active rotating shaft 2 and the driven rotating shaft 3 are arranged horizontally along the same axis. One of the active rotating shaft 2 and the driven rotating shaft 3 is provided with an air slip ring 7, and the other of the active rotating shaft 2 and the driven rotating shaft 3 is provided with an electric slip ring 8.

[0026] By adopting the above technical solution, the air slip ring 7 can be set on the driven rotating shaft 3, while the electric slip ring 8 can be set on the driving rotating shaft 2; of course, their positions can also be interchanged. The drive motor 5 can be a servo motor, whose rotation angle can be precisely controlled. The drive motor 5 drives the synchronous belt 63 transmission mechanism 6 to operate, which in turn drives the driving rotating shaft 2 to rotate. Then, the rotating platform 4 rotates, driving the driven rotating shaft 3 to rotate. Since the driving rotating shaft 2 and the driven rotating shaft 3 share the same axis, the electric slip ring 8 and the air slip ring 7 are coaxially integrated, ensuring the synchronization of pneumatic and electrical transmission and solving the problem of cable and air circuit entanglement.

[0027] The air slip ring 7 includes an internally connected air slip ring stator 71 and an air slip ring rotor 72. The air slip ring rotor 72 is linked to the driven rotating shaft 3. The driven rotating shaft 3 is provided with an air outlet 31 that communicates with the interior of the air slip ring rotor 72. The air slip ring stator 71 is connected to an external air passage. With this configuration, when the rotating platform 4 rotates, the driven rotating shaft 3 drives the air slip ring rotor 72 to rotate, while the air slip ring stator 71 is connected to the external air passage for air supply. By providing an air outlet 31 on the driven rotating shaft 3, air supply to the external air passage is ensured while preventing the air pipe from getting tangled.

The electric slip ring rotor 82 is connected to a rotor wire 83, and the electric slip ring stator 81 is connected to a stator wire 84. The electric slip ring rotor 82 is connected to the active rotating shaft 2. A conductive ring connected to the rotor wire 83 is disposed inside the electric slip ring rotor 82. The electric slip ring stator 81 includes brush filaments, one end of which is connected to the stator wire 84 and the other end of which abuts against the conductive ring.

The end cover plate 91 is located on one side of the sensing element 9. The end cover plate 91 is provided with multiple sensors 92 that are at an angle to each other. The sensors 92 can be specifically set as proximity sensors 92. Since the end cover plate 91 is fixed, the sensing element 9 moves closer to different proximity sensors 92 as the driven rotating shaft 3 rotates, thereby realizing the detection of the rotation origin and rotation angle of the rotating platform 4.

[0030] Furthermore, the rotating platform 4 is equipped with a processing device 41, a positioning fixture 42, and a material placement mechanism 43. The material placement mechanism 43 includes a mounting plate 44, a clamping cylinder 45 mounted on the mounting plate 44, a material receiving plate 46 mounted above the clamping cylinder 45, and a clamping block 47 connected to the clamping cylinder 45 and capable of clamping the material in the material receiving plate 46. The processing device 41 can be a welding gun or a grinding head to perform welding or grinding operations. In this specific embodiment, the processing device 41 is a grinding head, which facilitates on-site training for students. The positioning fixture 42 is used to position the material, and the material receiving plate 46 holds the material to be processed. The clamping cylinder 45 drives the clamping block 47 to clamp and position the material in the material receiving plate 46. Furthermore, the processing device 41 is located on the rotating platform 4 on one side of the electric slip ring 8, and the clamping cylinder 45 is located on the rotating platform 4 on one side of the air slip ring 7. This arrangement facilitates the connection of the processing device 41 to the cable and the connection of the clamping cylinder 45 to the air circuit, making the structural layout more reasonable.
