[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Example:
[0037] like Figure 1-7 As shown, this embodiment proposes a multi-directional alignment and positioning device for a disc shaft assembly 80, which is used to position the disc shaft assembly 80. The device includes a base plate 10, on which a support plate 20 is provided.
[0038] An adjusting plate 50 is also provided on the base plate 10. The adjusting plate 50 is displaced and adjusted along the long side of the base plate 10. A supporting clamp 30 is provided on the supporting plate 20. An adjusting clamp 60 is provided on the adjusting plate 50. A lifting assembly 70 is also provided on the adjusting plate 50. The adjusting clamp 60 is connected to the lifting assembly 70, so that the adjusting clamp 60 is raised and lowered to adjust the height, thereby driving the shaft on the disc shaft assembly 80 to maintain a horizontal state between the supporting clamp 30 and the adjusting clamp 60.
[0039] In this embodiment, when aligning the disc shaft assembly 80, the position of the adjusting plate 50 on the base plate 10 is adjusted until the distance between the adjusting plate 50 and the support plate 20 matches the shaft length of the disc shaft assembly 80. Then, the adjusting clamp 60 is raised or lowered by the lifting assembly 70 so that the shaft on the disc shaft assembly 80 remains horizontal between the support clamp 30 and the adjusting clamp 60. Then, the shaft of the disc shaft assembly 80 is fixed by the support clamp 30 and the adjusting clamp 60. The disc on the disc shaft assembly 80 is manually rotated between the support clamp 30 and the adjusting clamp 60, and the shaft is aligned by contacting the position to be tested with a dial indicator.
[0040] By adjusting the displacement of the adjusting plate 50 along the long side of the base plate 10, and by adjusting the height of the adjusting clamp 60 by the lifting component 70, shafts of different lengths can be adapted to each other and their levelness can be precisely adjusted, so that the disc shaft assembly 80 can quickly reach a horizontal positioning state in both length and height directions, providing a stable benchmark for subsequent alignment operations.
[0041] The support fixture 30 and the adjusting fixture 60 work together to flexibly clamp and fix the shaft, ensuring that the shaft remains stable during rotation. Combined with the lever dial indicator, the measurement accuracy is significantly improved, the time spent on repeated manual adjustments is reduced, the alignment efficiency and measurement accuracy are significantly improved, and the complexity of the equipment and the operating cost are reduced.
[0042] Specifically, the support clamp 30 includes a support frame 36, and a support through groove 35 is provided between the support plate 20 and the support frame 36;
[0043] The support plate 20 is symmetrically provided with two sets of first support bearings 21 that are rotatably connected, and the support frame 36 is provided with a second support bearing 37 that is rotatably connected, with the second support bearing 37 positioned between the two sets of first support bearings 21.
[0044] In this embodiment, when fixing the shaft of the disc shaft assembly 80, the shaft is placed in the support through groove 35 so that the shaft contacts the first support bearing 21. Then, by pressing down the second support bearing 37, the shaft is positioned on the two sets of first support bearings 21.
[0045] Specifically, the support frame 36 is provided with two sets of support connection parts 32, and support bolts 31 are provided between the support connection parts 32 and the support plate 20;
[0046] The support connection part 32 is slidably connected to the support bolt 31, and the support connection part 32 is threadedly connected to the support plate 20.
[0047] Specifically, a support spring 34 is sleeved on the outer wall of the support bolt 31, and a support washer 33 is also sleeved on the outer wall of the support bolt 31. The support washer 33 contacts the support connection part 32, and the head of the support bolt 31 contacts the support spring 34, so that the support washer 33 is pressed against the support connection part 32.
[0048] In this embodiment, when the shaft of the disc shaft assembly 80 is placed in the support through groove 35, the support spring 34 is compressed from its original normal state. Under the action of elastic potential energy, the second support bearing 37 can always press against the surface of the shaft to ensure the stability of the shaft during rotation.
[0049] Specifically, the adjusting fixture 60 includes an adjusting frame 66, and an adjusting through groove 63 is provided between the adjusting plate 50 and the adjusting frame 66;
[0050] The adjusting plate 50 is symmetrically provided with two sets of first adjusting bearings 51 that are rotatably connected, and the adjusting frame 66 is provided with a second adjusting bearing 67 that is rotatably connected, and the second adjusting bearing 67 is located between the two sets of first adjusting bearings 51.
[0051] In this embodiment, when fixing the shaft of the disc shaft assembly 80, the shaft is placed in the adjustment slot 63 so that the shaft contacts the first adjustment bearing 51. Then, by pressing down the second adjustment bearing 67, the shaft is positioned on the two sets of first adjustment bearings 51.
[0052] Specifically, the adjustment frame 66 is provided with two sets of adjustment connecting parts 62, and an adjustment bolt 61 is provided between the adjustment connecting parts 62 and the adjustment plate 50;
[0053] The adjusting connection part 62 is slidably connected to the adjusting bolt 61, and the adjusting connection part 62 is threadedly connected to the adjusting plate 50.
[0054] Specifically, an adjusting spring 65 is fitted on the outer wall of the adjusting bolt 61, and an adjusting shim 64 is also fitted on the outer wall of the adjusting bolt 61. The adjusting shim 64 contacts the adjusting connection part 62, and the head of the adjusting bolt 61 contacts the adjusting spring 65, so that the adjusting shim 64 is pressed against the adjusting connection part 62.
[0055] In this embodiment, when the shaft of the disc shaft assembly 80 is placed in the adjusting groove 63, the adjusting spring 65 is compressed from its original normal state. Under the action of elastic potential energy, the second adjusting bearing 67 can always press against the surface of the shaft to ensure the stability of the shaft during rotation.
[0056] Specifically, the base plate 10 is provided with two sets of movable T-slots 13, and the adjusting plate 50 is provided with a movable plate 40;
[0057] Two sets of movable T-blocks 41 are symmetrically arranged at the bottom end of the movable plate 40. The movable T-blocks 41 are provided with threaded holes 42. A screw 11 is rotatably arranged in the movable T-slot 13. The screw 11 is threadedly connected to the threaded hole 42. The screw 11 is provided with an internal hexagonal hole 12.
[0058] In this embodiment, when the distance between the adjusting plate 50 and the support plate 20 is adapted to the length of the shaft, an internal hex wrench is inserted into the internal hex hole 12 to drive the screw 11 to rotate. Through the threaded engagement between the screw 11 and the threaded hole 42, the movable T-block 41 is displaced in the movable T-slot 13, thereby completing the displacement adjustment process of the adjusting plate 50 to adapt to shafts of different lengths.
[0059] Specifically, the movable plate 40 is provided with two sets of lifting and reinforcing plates 43, and the lifting assembly 70 is disposed between the lifting and reinforcing plates 43;
[0060] Two sets of fixed plates 44 are provided between the two sets of lifting and reinforcing plates 43. The adjusting plate 50 is slidably disposed between the two sets of fixed plates 44. The adjusting plate 50 is also slidably disposed between the two sets of lifting and reinforcing plates 43.
[0061] Specifically, the lifting assembly 70 includes a lifting bolt 72, which is rotatably mounted on the movable plate 40 and is also threadedly connected to the adjusting plate 50.
[0062] An adjusting nut 71 is fixedly installed on the outer wall of the lifting bolt 72.
[0063] In this embodiment, when the shaft on the disc shaft assembly 80 needs to be in a horizontal state, the adjusting nut 71 is rotated by a wrench, thereby causing the lifting bolt 72 to rotate. Through the threaded engagement between the lifting bolt 72 and the adjusting plate 50, the adjusting plate 50 is raised and lowered between the two sets of fixed plates 44 until the shaft on the disc shaft assembly 80 is in a horizontal state.
[0064] By using the threaded engagement between the lifting bolt 72 and the adjusting plate 50, combined with the operation of rotating the adjusting nut 71 driven by a wrench, the precise linear displacement of the adjusting plate 50 in the vertical direction is achieved. This design allows the shaft height of the disc assembly 80 to be finely adjusted to a precise horizontal state, providing a high-precision benchmark for subsequent alignment and testing. Moreover, the adjusting plate 50 is simultaneously slidably positioned between two sets of fixed plates 44 and two sets of lifting reinforcement plates 43, forming a multi-guide constraint structure. This design effectively limits the radial displacement of the adjusting plate 50 during the lifting process, ensuring the verticality and stability of the lifting trajectory and avoiding positioning errors caused by tilting.
[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
