Description

Technical Field

[0001] The invention relates to the technical field of angle adjustment devices, and in particular to a large-load angle adjustment device. Background Art

[0002] In the application scenarios of a large number of devices, it is necessary to use an angle adjustment device to adjust the installation or placement angle of the device. Especially in the use of optoelectronic products, the angle adjustment device can be used as an auxiliary device to realize the optical path alignment adjustment during initial installation and the direction adjustment during use. The angle adjustment device is mainly based on the optical adjustment frame and the angle translation stage. The optical adjustment frame generally adopts a thread and spring structure. This type of angle adjustment device needs to use a driving force to offset the deadweight of the load, the output torque is small, and the carrying capacity is very limited. The angle translation stage generally uses a transmission mechanism such as a lead screw guide or gear to convert the torque of the adjustment knob into the angular movement of the adjustment surface to achieve angle adjustment. This type of angle adjustment device needs to use a driving force to offset the surface friction caused by the deadweight of the load. The load weight determines the friction between the transmission mechanism. Therefore, the carrying capacity is closely related to the size of the transmission mechanism, and it is impossible to take into account the requirements of large carrying capacity and light weight. Moreover, a set of transmission mechanisms in the angle translation stage can only realize one-dimensional adjustment, and multi-dimensional adjustment can only be realized by superimposing the transmission mechanism. It also has the disadvantages of complex structure, heavy weight, and poor portability; at the same time, the transmission mechanism used in the angle adjustment device maintains the motion accuracy through high precision, and the device cost is high. In addition, optoelectronic products are generally supported by a tripod. Due to the large size and weight of the angle adjustment device, it is not suitable for application scenarios such as optical path alignment of optoelectronic equipment.

[0040] like Figures 1 to 6 As shown, this embodiment provides a large load-bearing angle adjustment device, which includes a mounting seat 6, a load mounting plate 1, a bracket mounting plate 2, a pitch adjustment mechanism and a horizontal adjustment mechanism. The device 7 to be adjusted is mounted on the load mounting plate 1, and the load mounting plate 1 is rotatably connected to the bracket mounting plate 2 through a bearing body 3. The bracket mounting plate 2 is mounted on the mounting seat 6. The pitch adjustment mechanism is used to adjust the pitch angle of the load mounting plate 1, and the horizontal adjustment mechanism is used to adjust the horizontal azimuth angle of the load mounting plate 1. The horizontal azimuth adjustment of the device 7 to be adjusted is achieved through the relative rotation of the load mounting plate 1 and the bracket mounting plate 2. The bearing body 3 is used as a rotation fulcrum, which has excellent load-bearing capacity. The horizontal azimuth rotation angle adjustment of the large device 7 to be adjusted and the pitch angle adjustment relative to the horizontal plane are achieved through the pitch adjustment mechanism and the horizontal adjustment mechanism. At the same time, it is only necessary to slightly adjust the size of each component of the angle adjustment device according to the weight parameter of the device 7 to be adjusted and the size of the mounting seat 6, without changing the structure of the angle adjustment device, to achieve the angle adjustment requirements of each device 7 to be adjusted, and the versatility is good.

[0041] Specifically, the mounting base 6 includes but is not limited to a tripod, which has stability and excellent load-bearing capacity and can be widely used in the installation of the angle adjustment device.

[0042] Preferably, weight-reducing holes are provided on the load mounting plate 1 and the bracket mounting plate 2 to reduce the weight of the load mounting plate 1 and the bracket mounting plate 2, reduce the deadweight of the angle adjustment device, and increase the scope of application.

[0043] Furthermore, the bearing body 3 is arranged between the load mounting plate 1 and the bracket mounting plate 2, and the bearing body 3 includes a bearing inner seat 31, a bearing outer seat 32 and a bearing rolling core 33. The bearing rolling core 33 is arranged between the bearing inner seat 31 and the bearing outer seat 32. The bearing inner seat 31 and the bearing outer seat 32 rotate relative to each other through the bearing rolling core 33. The bearing outer seat 32 is connected to the load mounting plate 1, and the bearing inner seat 31 is connected to the bracket mounting plate 2. The load mounting plate 1 and the bracket mounting plate 2 rotate relative to each other through the bearing rolling core 33, thereby realizing the horizontal azimuth adjustment of the device to be adjusted. At the same time, the bearing body 3 is used as a rotation fulcrum to replace the guide transmission device such as a guide rail or gear, which greatly reduces the transmission friction, which is inconsistent with the method of using the driving force to offset the surface friction caused by the dead weight of the load in the prior art, so that the dead weight of the angle adjustment device is greatly reduced while improving the bearing capacity of the angle adjustment device.

[0044] Furthermore, the bearing body 3 further includes a bearing rolling core inner pressure ring 34 and a bearing rolling core outer pressure ring 35, the bearing rolling core inner pressure ring 34 is located between the bearing inner seat 31 and the bearing rolling core 33, and the bearing rolling core outer pressure ring 35 is located between the bearing outer seat 32 and the bearing rolling core 33, the bearing rolling core inner pressure ring 34 and the bearing rolling core outer pressure ring 35 play a role in fixing and supporting the bearing inner seat 31, the bearing rolling core 33, and the bearing outer seat 32 in the bearing body 3, while maintaining the stability and normal operation of the bearing rolling core 33, preventing looseness and wear between the components, and increasing the service life of the bearing body 3; in addition. The bearing rolling core inner pressure ring 34 and the bearing rolling core outer pressure ring 35 have a relative movable space, which is convenient for the relative displacement of the load mounting plate 1 and the bracket mounting plate 2 when the pitch angle is adjusted, thereby driving the relative displacement of the bearing inner seat 31 and the bearing outer seat 32.

[0045] Specifically, the pitch adjustment mechanism includes at least four pitch adjustment components 4, each of which includes a pitch adjustment knob 41. A first adjustment hole is provided on the bracket mounting plate 2. The pitch adjustment knob 41 is adjustable in height direction and penetrates the first adjustment hole and abuts against the load mounting plate 1. By manually slightly adjusting the pitch adjustment knob 41, the pitch adjustment knob 41 is driven to move up and down in the first adjustment hole, thereby adjusting the pitch angle of the load mounting plate 1, and the pitch angle adjustment of the large-scale device 7 to be adjusted relative to the horizontal plane can be achieved.

[0046] In this embodiment, the pitch adjustment mechanism includes four pitch adjustment components 4, wherein the contact points between the pitch adjustment knobs 41 of two pitch adjustment components 4 and the load mounting plate 1 pass through the rotation axis of the bearing body 3, and the contact points between the pitch adjustment knobs 41 of the other two pitch adjustment components 4 and the load mounting plate 1 also pass through the rotation axis of the bearing body 3. Figure 2As shown, the rotation centers of the pitch adjustment components E, G and the bearing body 3 are in a straight line, and the rotation centers of the pitch adjustment components F, H and the bearing body 3 are also in a straight line. At this time, the two pitch adjustment components 4 and the bearing body 3 are in a lever structure, and the bearing body 3 is used as the central support point. The distributed pitch adjustment knob 41 is used as a part for adjusting the torque. Under the same load weight, the force arm formed by the pitch adjustment knob 41 and the central support point can effectively reduce the size of the original required force. By using the principle of distributed levers, the bearing capacity is increased while the deadweight is reduced, and the convenience of using the angle adjustment device is improved. Of course, in other embodiments, the pitch adjustment mechanism includes or may include five or six or more pitch adjustment components 4, wherein at least four pitch adjustment components 4 are located at the position of the above embodiment, so that the two pitch adjustment components 4 and the bearing body 3 are in a lever structure, while the deadweight is reduced, the bearing capacity is increased. Setting more pitch adjustment components 4 can meet the needs of more angle adjustments, which is determined according to actual conditions.

[0047] Specifically, the pitch adjustment assembly 4 further includes a second limit seat 42, which is disposed on the load mounting plate 1, and the pitch adjustment knob 41 is provided with a first adjustment hole that can be adjusted in the height direction and abuts against the second limit seat 42. The second limit seat 42 is further provided to limit the adjustment of the pitch adjustment knob 41, so as to prevent the pitch adjustment knob 41 from moving to the weight-reducing hole of the load mounting plate 1 or other connection structures during the adjustment process when the load mounting plate 1 is used for limit abutment, thereby affecting the pitch angle adjustment.

[0048] Preferably, a first limiting groove is provided at one end of the second limiting seat 42 close to the pitch adjustment knob 41. The pitch adjustment knob 41 moves only in the groove of the first limiting groove, so as to prevent the pitch adjustment knob 41 from moving out of the second limiting seat 42 during various angle adjustment processes, and from being separated from the second limiting seat 42, thereby affecting the adjustment of the pitch angle or the horizontal azimuth angle.

[0049] Furthermore, the pitch adjustment knob 41 includes a pitch knob rod 411, which is threadedly connected to the first adjustment hole. Under the action of the thread rotation, the pitch knob rod 411 moves up and down, thereby driving the second limit seat 42 to move up and down, and realizing the pitch angle adjustment of the load mounting plate 1. While using the lever principle to reduce the thrust required for angle adjustment, only the torque of the thread transmission is used instead of the linear thrust to achieve continuous and stable angle movement, thereby improving the convenience of the device, and at the same time, it can adjust large-load equipment and increase the scope of application.

[0050] Furthermore, the pitch adjustment knob 41 also includes a pitch knob head 412, which is arranged at one end of the pitch knob rod 411 away from the second limit seat 42. By rotating the pitch knob head 412, the pitch knob rod 411 is driven to move, which facilitates the angle adjustment operation. Exemplarily, the pitch knob head 412 adopts a knurling process or an ergonomically designed handle, and the knurling process is used to increase the hand friction of the operator when adjusting the angle, improve the adjustment efficiency, and use ergonomic design to increase the comfort of operation.

[0051] Preferably, the end of the pitch knob rod 411 that contacts the load mounting plate 1 is hemispherical. The hemispherical design allows the pitch knob rod 411 to be in point contact with the second limit seat 42. When adjusted to a desired angle, any point of the hemispherical structure can abut against the second limit seat 42. The angle can be adjusted simply by moving the pitch adjustment knob 41 up and down, which is suitable for small angle adjustment and convenient for angle adjustment.

[0052] Specifically, the horizontal adjustment mechanism includes at least four horizontal adjustment components 5, each of which includes a horizontal adjustment knob 51, a first limit seat 52 and a first mounting seat 53. The first limit seat 52 is arranged on the load mounting plate 1, and the first mounting seat 53 is arranged on the bracket mounting plate 2. The first mounting seat 53 is provided with a second adjustment hole. The horizontal adjustment knob 51 is adjustable in position along a first direction and penetrates the second adjustment hole and abuts against the first limit seat 52. The first direction is perpendicular to the height direction. Figure 3 The direction pointed by the middle shear head W is the first direction. By manually slightly adjusting the horizontal adjustment knob 51, the horizontal adjustment knob 51 is driven to move forward and backward in the second adjustment hole, thereby adjusting the horizontal azimuth angle of the load mounting plate 1, and the horizontal azimuth rotation angle adjustment of the large-scale equipment 7 to be adjusted can be achieved.

[0053] In this embodiment, the horizontal adjustment mechanism includes four horizontal adjustment components 5, wherein the contact point connection line between the horizontal adjustment knobs 51 of two horizontal adjustment components 5 and the first limit seat 52 passes through the rotation axis of the bearing body 3, and the contact point connection line between the horizontal adjustment knobs 51 of the other two horizontal adjustment components 5 and the first limit seat 52 also passes through the rotation axis of the bearing body 3. Figure 3As shown, the rotation centers of the horizontal adjustment components A, C and the bearing body 3 are in a straight line, and the rotation centers of the horizontal adjustment components B, D and the bearing body 3 are also in a straight line. At this time, the two horizontal adjustment components 5 and the bearing body 3 are in a lever structure. The bearing body 3 is the central support point and the rotation center of the horizontal rotation movement. The distributed horizontal adjustment knob 51 is used as a part for adjusting the torque. Under the same load weight, the force arm between the top force point formed by the horizontal adjustment knob 51 and the central support point can effectively reduce the size of the original required top force. By utilizing the principle of distributed levers and the characteristics of small sliding friction of the rolling core 33 of the bearing, the load-bearing capacity is improved while reducing the dead weight, and the convenience of using the angle adjustment device is improved. Of course, in other embodiments, the horizontal adjustment mechanism includes or may include five or six or more horizontal adjustment components 5, wherein at least four horizontal adjustment components 5 are located at the position of the above embodiment, so that the two horizontal adjustment components 5 and the bearing body 3 are in a lever structure, which reduces the dead weight while improving the load-bearing capacity. Setting more horizontal adjustment components 5 can meet the needs of more angle adjustments, which is determined according to actual conditions.

[0054] Furthermore, the horizontal adjustment knob 51 includes a horizontal knob rod 511, which is threadedly connected to the second adjustment hole. Under the action of the thread rotation, the horizontal knob rod 511 moves forward and backward, thereby driving the first limit seat 52 to move forward and backward, and realizing the horizontal position adjustment of the load mounting plate 1. While using the lever principle to reduce the thrust required for angle adjustment, only the torque of the thread transmission is used instead of the linear thrust to achieve continuous and stable angle movement, thereby improving the convenience of the device, and at the same time, it can adjust large-load equipment and increase the scope of application.

[0055] Furthermore, the horizontal adjustment knob 51 also includes a horizontal knob head 512, which is arranged at one end of the horizontal knob rod 511 away from the first limit seat 52. By rotating the horizontal knob head 512, the horizontal knob rod 511 is driven to move, which facilitates the angle adjustment operation. Exemplarily, the horizontal knob head 512 adopts a knurling process or an ergonomically designed handle, and the knurling process is used to increase the hand friction of the operator when adjusting the angle, improve the adjustment efficiency, and use ergonomic design to increase the comfort of operation.

[0056] Preferably, the end of the horizontal knob rod 511 that contacts the first limit seat 52 is hemispherical. The hemispherical design allows the horizontal knob rod 511 to be in point contact with the first limit seat 52. When adjusted to a desired angle, any point of the hemispherical structure can abut against the first limit seat 52. Angle adjustment can be achieved by simply moving the horizontal adjustment knob 51 forward and backward, which is suitable for small angle adjustment and convenient for angle adjustment.

[0057] Preferably, a second limit groove is provided at one end of the first limit seat 52 close to the horizontal adjustment knob 51, and the horizontal adjustment knob 51 only moves in the groove of the second limit groove to prevent the horizontal adjustment knob 51 from moving out of the first limit seat 52 during various angle adjustments and detaching from the first limit seat 52, thereby affecting the adjustment of the pitch angle or the horizontal azimuth angle.

[0058] Specifically, each structure of the angle adjustment device is manufactured using universal standardized parts, which has low cost, simple structure, light weight and good portability.

[0059] It should be noted that in actual application, the horizontal adjustment angle range is small. When adjusting the horizontal angle, the pitch adjustment knob 41 will not disengage from the first limit groove; the pitch angle adjustment range is also small. When adjusting the pitch angle, the horizontal adjustment knob 51 will not disengage from the second limit groove.

[0060] In this embodiment, the specific angle adjustment adopts the following operation steps:

[0061] When adjusting the horizontal azimuth angle, a staggered tightening and staggered loosening method is adopted. When the horizontal adjustment knob 51 is rotated until the horizontal knob rod 511 abuts against the first limit seat 52, the horizontal adjustment knob 51 is tightened, and when the horizontal adjustment knob 51 is rotated in a direction away from the first limit seat 52, the horizontal adjustment knob 51 is loosened. In the initial state, the horizontal adjustment knobs A, B, C, and D are all in a tightened state. When the horizontal azimuth direction needs to be adjusted counterclockwise, loosen the horizontal adjustment knobs A and C, rotate the load mounting plate 1 counterclockwise relative to the bracket mounting plate 2 through the bearing body 3, and when the angle is adjusted in place, tighten and lock the horizontal adjustment knobs A and C, and tighten the horizontal adjustment knobs D and B that were loosened after the angle adjustment; when the horizontal azimuth direction needs to be adjusted clockwise, loosen the horizontal adjustment knobs D and B, rotate the load mounting plate 1 counterclockwise relative to the bracket mounting plate 2 through the bearing body 3, and when the angle is adjusted in place, tighten and lock the horizontal adjustment knobs D and B, and tighten the horizontal adjustment knobs A and C that were loosened after the angle adjustment. The adjustment of the horizontal azimuth angle is completed.

[0062] When adjusting the pitch angle, the pitch adjustment knob 41 is rotated until the pitch knob rod 411 abuts against the second limit seat 42, and the pitch adjustment knob 41 is tightened. When the pitch adjustment knob 41 is rotated in the direction away from the second limit seat 42, the pitch adjustment knob 41 is loosened. The pitch angle can be adjusted by adjusting any one or two of the pitch adjustment knobs 41, namely, the pitch adjustment knob E, the pitch adjustment knob F, the pitch adjustment knob G, and the pitch adjustment knob G; when the pitch adjustment knob 41 on one of the front and rear sides is loosened, moved up and down, and then tightened, the front and rear pitch adjustment is achieved; when the pitch adjustment knob 41 on one of the left and right sides is loosened, moved up and down, and then tightened, the left and right pitch adjustment is achieved; when any one of the pitch adjustment knobs 41 is loosened, moved up and down, and then tightened, the pitch adjustment of any tilt angle is achieved. Among them, taking the front and rear pitch adjustment and the left and right pitch adjustment as examples:

[0063] Adjust the pitch angle forward and backward: in the initial state, the pitch adjustment knob E, pitch adjustment knob F, pitch adjustment knob G, and pitch adjustment knob H are all in a tightened state. When the pitch direction needs to be adjusted forward and backward, loosen the pitch adjustment knob G and the pitch adjustment knob H. When the angle is adjusted to the right position, tighten and lock the pitch adjustment knob G and the pitch adjustment knob H, and then tighten and lock the pitch adjustment knob E and the pitch adjustment knob F that were loosened after the angle adjustment; or loosen the pitch adjustment knob E and the pitch adjustment knob F. When the angle is adjusted to the right position, tighten and lock the pitch adjustment knob E and the pitch adjustment knob F; then tighten and lock the pitch adjustment knob G and the pitch adjustment knob H that were loosened after the angle adjustment to complete the pitch angle adjustment.

[0064] Adjust the pitch angle left and right: In the initial state, the pitch adjustment knobs E, F, G, and H are all tightened. When the pitch direction needs to be adjusted left and right, loosen the pitch adjustment knobs G and F. When the angle is adjusted to the right, tighten and lock the pitch adjustment knobs G and F, and then tighten the pitch adjustment knobs E and H that were loosened after the angle adjustment; or loosen the pitch adjustment knobs E and H. When the angle is adjusted to the right, tighten and lock the pitch adjustment knobs E and H, and then tighten the pitch adjustment knobs G and F that were loosened after the angle adjustment to complete the roll angle adjustment.

[0065] For example, Figure 6As shown, the angle adjustment device is used to adjust the angle of the photoelectric device. The device to be adjusted 7 is a photoelectric device of 100 kg, which is installed on the load mounting plate 1. The mounting seat 6 is supported by a tripod, and the tripod is connected to the bracket mounting plate 2, that is, the angle adjustment device is installed between the photoelectric device and the tripod. The angle of the photoelectric device is adjusted through the above angle adjustment operation steps. Since the photoelectric device has a beam alignment requirement, the beam needs to be aligned with a certain characteristic position in the distance. By adjusting the horizontal adjustment knob 51 and the pitch adjustment knob 41 of the angle adjustment device, the loaded photoelectric device is driven to adjust the angle to achieve the adjustment of the beam direction.
