Abstract
Description
Technical Field
[0001] This utility model relates to the field of posture adjustment device technology, and more specifically, to a two-dimensional posture adjustment device using a worm gear structure. Background Technology
[0002] Attitude adjustment devices are mainly used in optical experiments and optoelectronic instruments for fixing and adjusting optical components, and are indispensable in precision optical instruments.
[0003] Attitude adjustment devices commonly include one-dimensional and two-dimensional devices. One-dimensional devices can only adjust one rotational degree of freedom, while two-dimensional devices can adjust two rotational degrees of freedom in different directions and are more common.
[0004] Current two-dimensional attitude adjustment devices are formed by superimposing two one-dimensional attitude adjustment devices. While modularizing, this results in the two rotational degree-of-freedom axes not intersecting. This means that after adjusting one degree of freedom, a displacement adjustment device is needed to adjust the displacement before adjusting the other degree of freedom. As can be seen, current two-dimensional attitude adjustment devices often require an additional displacement adjustment device to work together, which leads to inconvenience in adjustment, high cost, and poor economic efficiency.

[0040] As can be seen from the above, in this embodiment, the two-dimensional attitude adjustment device with a worm gear structure provided by this utility model includes a pitch rotation assembly, a roll rotation assembly, a rotating platform, a pitch manual adjustment assembly, a roll manual adjustment assembly, a pitch locking screw, and a roll locking screw; the pitch rotation assembly includes a first pitch shaft and a second pitch shaft coaxially arranged in a first direction; the roll rotation assembly includes a first worm, a roll locking threaded hole, a first pitch shaft hole and a second pitch shaft hole coaxially arranged in the first direction, and a first roll shaft and a second roll shaft coaxially arranged in a second direction; the rotating platform includes a second worm, a pitch locking threaded hole, and a first roll shaft hole and a second roll shaft hole coaxially arranged in the second direction; the pitch manual adjustment assembly includes a first worm, and the roll manual adjustment assembly includes a second worm; the first pitch shaft is rotatably mounted on... The first pitch axis is rotatably mounted in the second pitch axis hole, the first roll axis is rotatably mounted in the first roll axis hole, and the second roll axis is rotatably mounted in the second roll axis hole; the pitch manual adjustment assembly is mounted on the pitch rotation assembly and the first worm gear meshes with the first worm; the pitch locking screw is threadedly connected to the pitch locking threaded hole; the pitch manual adjustment assembly can rotate to multiple pitch adjustment positions; when the pitch manual adjustment assembly rotates to the pitch adjustment position, the pitch locking screw is locked; the roll manual adjustment assembly is mounted on the roll rotation assembly and the second worm gear meshes with the second worm; the roll locking screw is threadedly connected to the roll locking threaded hole; the roll manual adjustment assembly can rotate to multiple roll adjustment positions; when the roll manual adjustment assembly rotates to the roll adjustment position, the roll locking screw is locked; wherein, the first direction and the second direction are perpendicular to each other. Therefore, by rotating the pitch manual adjustment component mounted on the pitch rotation assembly, the first worm gear drives the first turbine to rotate, and the first turbine drives the roll rotation assembly to pitch around the first pitch axis and the second pitch axis. Since the rotating platform is mounted on the roll rotation assembly, the rotating platform also pitches and rotates with the roll rotation assembly, realizing the adjustment of the pitch degree of freedom. When the corresponding pitch adjustment position is reached, the pitch locking screw is tightened to fix it. Then, by rotating the roll manual adjustment component, the second worm gear drives the second turbine to rotate, and the second turbine drives the rotating platform to roll around the first roll axis and the second roll axis. The axis rolls, allowing for adjustment of the roll degree of freedom. When the roll is adjusted to the corresponding adjustment position, the roll locking screw is tightened to fix it. This allows for adjustment of the pitch and roll degrees of freedom of the device to be adjusted mounted on the rotating platform. This is because the axes of the first pitch axis and the second pitch axis intersect the axes of the first roll axis and the second roll axis in a cross shape, with an included angle of 90° and intersecting at a point. This ensures that the device to be adjusted on the rotating platform can rotate around the intersection point with two degrees of freedom without the need for additional displacement adjustment devices. This makes adjustment convenient, reduces costs, and improves economy.
[0041] The innovative aspects of this utility model embodiment include:
[0042] 1. By rotating the pitch manual adjustment assembly mounted on the pitch rotation assembly, the first worm gear drives the first turbine to rotate. The first turbine drives the roll rotation assembly to pitch around the first pitch axis and the second pitch axis. Since the rotating platform is mounted on the roll rotation assembly, the rotating platform also pitches and rotates with the roll rotation assembly, realizing the adjustment of the pitch degree of freedom. When the corresponding pitch adjustment position is reached, the pitch locking screw is tightened to fix it. Then, by rotating the roll manual adjustment assembly, the second worm gear drives the second turbine to rotate. The second turbine drives the rotating platform to pitch around the first roll axis and the second roll axis. The axis rolls, allowing for adjustment of the roll degree of freedom. When the roll is adjusted to the corresponding adjustment position, the roll locking screw is tightened to fix it. This allows for adjustment of the pitch and roll degrees of freedom of the device to be adjusted mounted on the rotating platform. This is because the axes of the first pitch axis and the second pitch axis intersect the axes of the first roll axis and the second roll axis in a cross shape, with an included angle of 90° and intersecting at a point. This ensures that the device to be adjusted on the rotating platform can rotate around the intersection point with two degrees of freedom without the need for additional displacement adjustment devices. This makes adjustment convenient, reduces costs, and improves economy.
[0043] 2. Since the axes of the first pitch axis and the second pitch axis intersect the axes of the first roll axis and the second roll axis in a cross shape, and the included angle is 90° and they intersect at a point, the axis of the first roll axis and the axis of the second roll axis will not change after adjusting the pitch degree of freedom. Therefore, there is no need to add an additional displacement adjustment device to cooperate in adjusting the roll degree of freedom, and the adjustment is convenient.
[0044] 3. When the pitch manual adjustment component is rotated to the pitch adjustment position, the pitch locking screw is used to lock it, which can ensure that the rotary platform does not move slightly after the pitch degree of freedom is adjusted. Similarly, when the roll manual adjustment component is rotated to the roll adjustment position, the roll locking screw is used to lock it, which can ensure that the rotary platform does not move slightly after the roll degree of freedom is adjusted, thus improving the adjustment accuracy.
[0045] 4. The two-dimensional attitude adjustment device with a worm gear structure provided in this embodiment of the utility model adopts an open structure without a shell, which is convenient for maintenance.
[0046] 5. By fixing the first near-axis end bushing and the first far-axis end bushing to both ends of the first through hole respectively, the wear resistance of the components installed in the first through hole is enhanced, thereby increasing their service life.
[0047] 6. By setting a first rotating step shaft through a first through hole, one end of a first knurled hand-tightening nut located outside the first through hole, and a first snap ring locking groove provided on the outer side of the shaft body of the second step shaft extending out of the first through hole, the first snap ring is locked in the first snap ring locking groove, and the first snap ring abuts against the first far-axis end bushing, thereby realizing that the pitch manual adjustment component can rotate in the first through hole and prevent its axial movement.
[0048] 7. By fixing the first pitch axis bushing to the inside of the first pitch axis hole and the second pitch axis bushing to the inside of the second pitch axis hole, the wear resistance of the first pitch axis installed in the first pitch axis hole is enhanced to increase its service life, and the wear resistance of the second pitch axis installed in the second pitch axis hole is enhanced to increase its service life.
[0049] 8. By fixing the second proximal end bushing and the second distal end bushing to both ends of the seventh through hole respectively, the wear resistance of the components installed in the seventh through hole is enhanced, thereby increasing their service life.
[0050] 9. The first turbine is mounted on the rolling base using two first fixing screws.
[0051] 10. By setting a second rotating step shaft through the seventh through hole, one end of the second knurled hand-tightening nut is located outside the seventh through hole, and a second snap ring locking groove is provided on the outer side of the shaft body of the fourth step shaft extending out of the seventh through hole. The second snap ring is locked in the second snap ring locking groove, and the second snap ring abuts against the second far-shaft end bushing, thereby realizing that the rolling manual adjustment component can rotate in the seventh through hole and prevent its axial movement.
[0052] 11. By fixing the first rolling bushing to the inside of the first rolling shaft hole and fixing the second rolling bushing to the inside of the second rolling shaft hole, the wear resistance of the first rolling shaft installed in the first rolling shaft hole is enhanced to increase its service life, and the wear resistance of the second rolling shaft installed in the second rolling shaft hole is enhanced to increase its service life.

[0072] The manual pitch adjustment assembly 4 is mounted on the pitch rotation assembly 1, and the first worm gear 21 meshes with the first worm 41. The pitch locking screw 6 is threadedly connected to the pitch locking threaded hole 32. The manual pitch adjustment assembly 4 can rotate to multiple pitch adjustment positions. When the manual pitch adjustment assembly 4 is rotated to the pitch adjustment position, the pitch locking screw 32 is locked. Since the first pitch shaft 11 is rotatably mounted in the first pitch shaft hole and the second pitch shaft 12 is rotatably mounted in the second pitch shaft hole, when the manual pitch adjustment assembly 4 is rotated, the roll rotation assembly 2 can pitch and rotate around the first pitch shaft 11 and the second pitch shaft 12.

[0076] The working principle of the two-dimensional attitude adjustment device with a worm gear structure provided in this embodiment of the utility model is as follows:
[0077] First, by rotating the pitch manual adjustment component 4 installed on the pitch rotation component 1, the first worm gear 41 drives the first turbine 21 to rotate. The first turbine 21 drives the roll rotation component 2 to pitch around the first pitch axis 11 and the second pitch axis 12. Since the rotating platform 3 is installed on the roll rotation component 2, the rotating platform 3 also pitches and rotates with the roll rotation component 2 to achieve the adjustment of the pitch degree of freedom. When the pitch adjustment position is reached, the pitch locking screw 32 is locked to fix it.
[0078] Secondly, by rotating the manual adjustment component 5, the second worm gear drives the second turbine 31 to rotate, and the second turbine 31 drives the rotating platform 3 to roll around the first rolling shaft 23 and the second rolling shaft, thereby adjusting the degree of freedom of rolling. When the rolling adjustment position is reached, the rolling locking screw 7 is tightened to fix it.
[0079] In summary, the two-dimensional attitude adjustment device with a worm gear structure provided in this embodiment includes a pitch rotation assembly 1, a roll rotation assembly 2, a rotating platform 3, a pitch manual adjustment assembly 4, a roll manual adjustment assembly 5, a pitch locking screw 6, and a roll locking screw 7.

The roll rotation assembly 2 includes a first turbine 21, a roll locking threaded hole 22, a first pitch shaft hole and a second pitch shaft hole coaxially arranged in the first direction, and a first roll shaft 23 and a second roll shaft coaxially arranged in a second direction. The rotating platform 3 includes a second turbine 31, a pitch locking threaded hole 32, and a first roll shaft hole and a second roll shaft hole coaxially arranged in the second direction. The pitch manual adjustment assembly 4 includes a first worm gear 41, and the roll manual adjustment assembly 5 includes a second worm gear. The first pitch shaft 21 is rotatably mounted on the first pitch shaft 21. Inside the pitch axis hole, the second pitch axis 22 is rotatably installed, the first roll axis 23 is rotatably installed, and the second roll axis is rotatably installed. The pitch manual adjustment assembly is installed on the pitch rotation assembly, and the first worm gear 21 meshes with the first worm 41. The pitch locking screw 6 is threadedly connected to the pitch locking threaded hole 32. The pitch manual adjustment assembly 4 can rotate to multiple pitch adjustment positions. When the pitch manual adjustment assembly 4 rotates to the pitch adjustment position, the pitch locking screw 32 is locked. The roll manual adjustment assembly 5 is installed on the roll rotation assembly 2, and the second worm gear 31 meshes with the second worm 51. The roll locking screw 7 is threadedly connected to the roll locking threaded hole 22. The roll manual adjustment assembly 5 can rotate to multiple roll adjustment positions. When the roll manual adjustment assembly 5 rotates to the roll adjustment position, the roll locking screw 7 is locked. The first direction and the second direction are perpendicular to each other.Therefore, by rotating the pitch manual adjustment assembly 4 installed on the pitch rotation assembly 1, the first worm gear 41 drives the first turbine 21 to rotate. The first turbine 21 drives the roll rotation assembly 2 to pitch around the first pitch axis 11 and the second pitch axis 12. Since the rotating platform 3 is installed on the roll rotation assembly 2, the rotating platform 3 also pitches and rotates with the roll rotation assembly 2, realizing the adjustment of the pitch degree of freedom. When the corresponding pitch adjustment position is reached, the pitch locking screw 32 is tightened to fix it. Then, by rotating the roll manual adjustment assembly 5, the second worm gear drives the second turbine 31 to rotate. The second turbine 31 drives the rotating platform 3 to rotate around the first pitch axis 11 and the second pitch axis 12. The rotating shaft 23 and the second rolling shaft rotate to adjust the rolling degree of freedom. When the corresponding rolling adjustment position is reached, the rolling locking screw 7 is tightened to fix it. This allows for the adjustment of the pitch and roll degrees of freedom of the device to be adjusted mounted on the rotating platform 3. This is because the axes of the first pitch shaft 11 and the second pitch shaft 12 intersect the axes of the first rolling shaft 23 and the second rolling shaft in a cross shape, with an included angle of 90° and intersecting at a point. This ensures that the device to be adjusted on the rotating platform 3 can rotate around the intersection point with two degrees of freedom without the need for additional displacement adjustment devices. This makes adjustment convenient, reduces costs, and improves economy.
[0080] Meanwhile, since the axes of the first pitch axis 11 and the second pitch axis 12 intersect the axes of the first roll axis 23 and the second roll axis in a cross shape, with an included angle of 90° and intersecting at a point, the axis of the first roll axis 23 and the axis of the second roll axis are not changed after adjusting the pitch degree of freedom. Therefore, there is no need to add an additional displacement adjustment device to cooperate in adjusting the roll degree of freedom, making adjustment convenient.
[0081] Furthermore, when the pitch manual adjustment component 4 is rotated to the pitch adjustment position, it is locked with the pitch locking screw 32 to ensure that the rotary platform 3 does not move with small displacement after the pitch degree of freedom is adjusted. Similarly, when the roll manual adjustment component 5 is rotated to the roll adjustment position, it is locked with the roll locking screw 7 to ensure that the rotary platform 3 does not move with small displacement after the roll degree of freedom is adjusted, thus improving the adjustment accuracy.
[0082] Furthermore, the two-dimensional attitude adjustment device with a worm gear structure provided in this embodiment of the present invention adopts an open structure without a shell enclosure, which facilitates maintenance.
[0083] See also Figure 2 The pitch rotation assembly 1 also includes a pitch rotation base 13, a first proximal end bushing 14, and a first distal end bushing 15, wherein the pitch rotation base 13 is the main structure of the pitch rotation assembly 1. The end closer to the first knurled hand-tightening nut 42 of the pitch manual adjustment assembly 4 is the proximal end, and the other end is the distal end.
[0084] The pitch rotation base 13 has a pitch manual adjustment component mounting bracket 131 and a first pitch axis mounting bracket 132 on one side surface along the third direction. The pitch manual adjustment component mounting bracket 131 has a first turbine mounting hole 133 and a second pitch axis mounting bracket 134 on the side surface away from the pitch rotation base 13. The pitch manual adjustment component mounting bracket 131 has a first through hole along the second direction, which communicates with the first turbine mounting hole 133. The first near-axis end bushing 14 and the first far-axis end bushing 15 are respectively fixedly installed at both ends of the first through hole. The bushings can be fixed in any of the existing technologies, which will not be described in detail here.
[0085] See also Figure 2 The first pitch axis mounting bracket 132 has a second through hole along a first direction, and the second pitch axis mounting bracket 134 has a third through hole along a second direction. The second and third through holes are coaxial. One end of the first pitch axis 11 is fixedly installed in the second through hole, and the other end of the first pitch axis 11 is rotatably installed in the first pitch axis hole. One end of the second pitch axis 12 is fixedly installed in the third through hole, and the other end of the second pitch axis 12 is rotatably installed in the second pitch axis hole. The method by which one end of the first pitch axis 11 is fixedly installed in the second through hole can be an interference fit. The method by which the other end of the first pitch axis 11 is rotatably installed in the first pitch axis hole can be that the diameter of the first pitch axis 11 is much smaller than the diameter of the first pitch axis hole, and the other end of the first pitch axis 11 passes through the first pitch axis hole and can rotate within it. The installation method of the second pitch axis 12 is similar to that of the first pitch axis 11, and will not be described again here.
[0086] Therefore, by fixing the first proximal end bushing 14 and the first distal end bushing 15 to the two ends of the first through hole respectively, the wear resistance of the component installed in the first through hole is enhanced, thereby increasing its service life.
[0087] See also Figure 5 The pitch manual adjustment assembly 4 also includes a first knurled hand-tightening nut 42, a first rotating step shaft 43, a first snap ring 44, a first nut locking screw 45, and a first worm gear locking screw 46.
[0088] The first knurled hand-tightening nut 42, the first rotating step shaft 43, and the first worm gear 41 all extend along the second direction. The rotating step shaft 43 includes a first step shaft 431 and a second step shaft 432, and the diameter of the first step shaft 431 is larger than the diameter of the second step shaft 432.
[0089] The first knurled hand-tightening nut 42 is fixedly connected to the first stepped shaft 431 via the first nut locking set screw 45, and the first worm gear 41 is fixedly connected to the second stepped shaft 432 via the first worm gear locking set screw 46.
[0090] The first rotating stepped shaft 431 passes through the first through hole, and one end of the first knurled hand-tightening nut 42 is located outside the first through hole. The second stepped shaft 432 extends out of the first through hole and is provided with a first snap ring locking groove. The first snap ring 44 is locked in the first snap ring locking groove and abuts against the first far-shaft end bushing 15.
[0091] In other words, the first through hole contains a part of the first rotating step shaft 431, a part of the first knurled hand-tightening nut 42, and the first worm gear 41. When the pitch manual adjustment assembly 4 is installed on the pitch adjustment assembly 1, it is locked in the first circlip locking groove by the first circlip 44, thereby preventing the axial movement of the pitch manual adjustment assembly 4.
[0092] The first knurled hand-tightening nut 42 includes a first knurled portion 421 and a first connecting portion 422 connected to each other. The first connecting portion 422 is fixedly connected to the first stepped shaft 431 by a first nut locking screw 45. The first knurled portion 421 is located outside the first through hole. Specifically, the first stepped shaft 431 is inserted into the axially arranged mounting hole of the first connecting portion 422, and then tightened into the axially arranged threaded hole of the first connecting portion 422 by the first nut locking screw 45, and is fixed in contact with the first stepped shaft 431.
[0093] Thus, by setting the first rotating stepped shaft 431 through the first through hole, one end of the first knurled hand-tightening nut 42 is located outside the first through hole, and the second stepped shaft 432 extends out of the first through hole and is provided with a first snap ring locking groove on the outside of the shaft body, and the first snap ring 44 is locked in the first snap ring locking groove, and the first snap ring 44 abuts against the first far-axis end bushing 15, the pitch manual adjustment component 4 can rotate in the first through hole and its axial movement is prevented.
[0094] See also Figure 3 The roll-rotation assembly 2 also includes a roll-rotation base 24, a second proximal end bushing 25, a second distal end bushing 26, a first pitch axis bushing 27, and a second pitch axis bushing, wherein the roll-rotation base 24 is mounted on the two pitch axes of the pitch-rotation assembly 1.
[0095] Specifically, the rolling and rotating base 24 has a fourth through hole 241 and a notch 242 on one side surface along the third direction, and a rolling manual adjustment component mounting bracket 243 is provided on the other side surface along the third direction. The rolling manual adjustment component mounting bracket 243 has a second turbine mounting hole at the end away from the pitch rotating base 13. The second turbine mounting hole is connected to the notch 242. The notch 242 is an opening with walls on only three sides, and the fourth through hole 241 is a rectangular through hole.
[0096] The rotating base 24 has a first protrusion 244 and a second protrusion 245 extending from both ends of the first direction to the third direction, respectively. The fourth through hole 241 is provided with a first pitch axis hole and a second pitch axis hole on the two side walls of the first direction, respectively. The fourth through hole 241 is provided with a fifth through hole and a sixth through hole on the two side walls of the second direction, respectively. The first protrusion 244 is provided with a rolling locking threaded hole 22.
[0097] See also Figure 3 The rolling manual adjustment component mounting bracket 243 is provided with a seventh through hole along the first direction. The seventh through hole is connected to the second turbine mounting hole. The second near-shaft end bushing 25 and the second far-shaft end bushing 26 are respectively fixedly installed at both ends of the seventh through hole. The bushing is fixed in any of the existing technologies, which will not be described in detail here.
[0098] The first pitch axis bushing 27 is fixedly installed inside the first pitch axis hole, and the second pitch axis bushing is fixedly installed inside the second pitch axis hole. The bushings can be fixed using any existing method, which will not be described further here.
[0099] Therefore, by fixing the first pitch axis bushing 27 to the inside of the first pitch axis hole and fixing the second pitch axis bushing to the inside of the second pitch axis hole, the wear resistance of the first pitch axis 11 installed in the first pitch axis hole is enhanced to increase its service life, and the wear resistance of the second pitch axis 12 installed in the second pitch axis hole is enhanced to increase its service life.
[0100] See also Figure 3 The first turbine 21 is fixedly installed inside the second protrusion 245, with one end of the first turbine 21 positioned in the first turbine mounting hole 133 and meshing with the first worm gear 41. One end of the first rolling shaft 23 is fixedly installed in the fifth through hole, and the other end of the first rolling shaft 23 is rotatably installed in the first rolling shaft hole. One end of the second rolling shaft is fixedly installed in the sixth through hole, and the other end of the second rolling shaft is rotatably installed in the second rolling hole. The installation method of the first rolling shaft 23 and the second rolling shaft is similar to that of the first pitch axis 11, and will not be described again here.
[0101] Therefore, by fixing the second proximal end bushing 25 and the second distal end bushing 26 to both ends of the seventh through hole, the wear resistance of the component installed in the seventh through hole is enhanced, thereby increasing its service life.
[0102] See also Figure 3 The rolling and rotating assembly 2 also includes two first fixing screws 28.
[0103] The second protrusion 245 is provided with two first threaded holes along the first direction, and the first turbine 21 is provided with two second threaded holes along the first direction. The two first threaded holes and the two second threaded holes correspond one to one. The first turbine 21 is fixedly connected to the second protrusion 245 through the first threaded holes, the second threaded holes, and the first fixing screw 28.
[0104] Thus, the first turbine 21 is mounted on the rolling base 24 by two first fixing screws 28.
[0105] Specifically, the manual adjustment assembly 5 also includes a second knurled hand-tightening nut, a second rotating step shaft, a second snap ring, a second nut locking screw, and a second worm gear locking screw.
[0106] The second knurled hand-tightening nut, the second rotating step shaft, and the second worm gear all extend along the first direction. The rotating step shaft includes a third step shaft and a fourth step shaft, and the diameter of the third step shaft is larger than the diameter of the fourth step shaft.
[0107] The second knurled hand-tightening nut is fixedly connected to the third stepped shaft via the second nut locking set screw, and the second worm gear is fixedly connected to the fourth stepped shaft via the second worm gear locking set screw.
[0108] The second rotating step shaft passes through the seventh through hole, one end of the second knurled hand-tightening nut is located outside the seventh through hole, and the fourth step shaft extends out of the seventh through hole and is provided with a second snap ring locking groove. The second snap ring is locked in the second snap ring locking groove and abuts against the second far-shaft end bushing.
[0109] In other words, the seventh through hole contains a part of the second rotating step shaft, a part of the second knurled hand-tightening nut, and a second worm gear. When the rolling manual adjustment component 5 is installed on the rolling rotation component 2, it is locked in the second snap ring groove by the second snap ring, thereby preventing the axial movement of the rolling manual adjustment component 5.
[0110] The second knurled hand-tightening nut includes a second knurled portion and a second connecting portion that are interconnected. The second connecting portion is fixedly connected to the third stepped shaft by a second nut locking screw. The second knurled portion is located outside the seventh through hole. Specifically, the third stepped shaft is inserted into the axially arranged mounting hole of the second connecting portion, and then the second nut locking screw is tightened into the axially arranged threaded hole of the second connecting portion and fixed in contact with the third stepped shaft.
[0111] Therefore, by setting the second rotating step shaft to pass through the seventh through hole, one end of the second knurled hand-tightening nut is located outside the seventh through hole, and the fourth step shaft extends out of the seventh through hole and is provided with a second snap ring locking groove on the outside of the shaft body. The second snap ring is locked in the second snap ring locking groove and the second snap ring abuts against the second far-shaft end bushing, thereby realizing that the rolling manual adjustment component 5 can rotate in the seventh through hole and prevent its axial movement.
[0112] See also Figure 4 The rotating platform 3 also includes a rolling rotary table 33, a first rolling bushing 34 and a second rolling bushing, wherein the rotating platform 3 is mounted on the rolling rotating assembly 2.
[0113] Specifically, the rotating table 33, as the main body of the rotating platform 3, is mounted on the rotating base 24. The rotating table 33 has a third protrusion 331 and a fourth protrusion 332 extending from both ends of the second direction to the third direction, respectively. The third protrusion 331 is provided with a first rotating shaft hole, and the fourth protrusion 332 is provided with a second rotating shaft hole. The first rotating shaft sleeve 34 is fixedly installed inside the first rotating shaft hole, and the second rotating shaft sleeve is fixedly installed inside the second rotating shaft hole. The fixing method of the shaft sleeve can be any fixing method in the prior art, which will not be described in detail here.
[0114] The second turbine 31 is fixedly installed on the inner side of the fourth protrusion 332, and one end of the second turbine 31 is set in the second turbine mounting hole and meshes with the second worm. The third protrusion 331 is provided with a pitch locking threaded hole 32 between the rolling rotary table 33 and the first rolling shaft hole.
[0115] Therefore, by fixing the first rolling bushing 34 to the inside of the first rolling shaft hole and fixing the second rolling bushing to the inside of the second rolling shaft hole, the wear resistance of the first rolling shaft 23 installed in the first rolling shaft hole is enhanced to increase its service life, and the wear resistance of the second rolling shaft installed in the second rolling shaft hole is enhanced to increase its service life.
[0116] See also Figure 4 The rotating platform 3 also includes two second fixing screws 35.
[0117] The fourth protrusion 332 is provided with two third threaded holes along the second direction, and the second turbine 31 is provided with two fourth threaded holes along the second direction. The two third threaded holes and the two fourth threaded holes correspond one to one. The second turbine 31 is fixedly connected to the fourth protrusion 332 through the third threaded holes, the fourth threaded holes, and the second fixing screw 35.
[0118] Thus, the second turbine 31 is mounted on the rotating platform 3 by two second fixing screws 35.
