Description

Technical Field

[0001] This invention belongs to the field of optical platform technology, and specifically relates to a vehicle-mounted two-degree-of-freedom optical platform. Background Technology

[0002] With the rapid development of technologies such as target tracking and photoelectric detection, the demand for performance testing and calibration of optical equipment (such as lasers and infrared detectors) is increasing, especially as application scenarios on mobile platforms (such as vehicles and ships) continue to expand. Vehicle-mounted modular units, as a highly mobile platform with good environmental adaptability, are often used as carriers for optical equipment in tasks such as field testing, mobile monitoring, and emergency response.

[0003] Testing optical equipment on mobile platforms such as vehicle-mounted shelters (e.g., pointing accuracy calibration, line-of-sight stability testing, dynamic performance verification) faces a core challenge: vibration and attitude disturbances in the vehicle environment. These factors can be directly transmitted to the onboard equipment, and may even damage the optical platform and equipment.

[0004] Currently, some automotive optical equipment uses simple rigid mounting brackets, but these methods limit the flexibility of testing and the verification of dynamic performance.

[0005] Existing two-degree-of-freedom platforms are not designed to withstand the harsh conditions of the vehicle environment. Therefore, there is an urgent need to design an optical testing support platform specifically for vehicle-mounted cabin environments. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a vehicle-mounted two-degree-of-freedom optical platform that enables the optical platform to be adjustable in two degrees of freedom.

[0007] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A vehicle-mounted two-degree-of-freedom optical platform includes a base fixed to the bottom plate of a container, an X-axis translation mechanism, a Z-axis rotation mechanism, and an optical platform disposed on a bottom platform above the base. The X-axis translation mechanism can drive the Z-axis rotation mechanism and the optical platform to translate on the bottom platform, and the Z-axis rotation mechanism can drive the optical platform to rotate. The base is equipped with vertically adjustable leveling legs. The X-axis translation mechanism includes an axial slide rail arranged on the bottom platform, an axial slide table slidably arranged on the axial slide rail, and a drive slide table arranged in the middle. The upper end of the axial slide table is fixedly connected to the rotating platform of the Z-axis rotation mechanism. The drive slide table drives the rotating platform to translate. The Z-axis rotation mechanism includes an annular gear disk fixed on a rotating platform, a second lead screw meshing with it, and a worm gear, and drives the annular gear disk to rotate under the action of the equipped drive device.

[0008] The axial slide is driven to move back and forth in translation under the action of the independently configured first servo motor and X-axis reduction handwheel. A first electromagnetic clutch is configured between the first servo motor and the first lead screw. The first lead screw is mounted on a bearing fixed on the bottom platform. When the power is not interrupted, the X-axis reduction handwheel rotates backward to disengage from the first lead screw, and the first servo motor directly drives the first lead screw and the axial slide to drive the X-axis translation mechanism to translate along the X-axis. When the power is off, the first electromagnetic clutch disconnects the first servo motor from the first lead screw. The X-axis reduction handwheel is manually operated to move forward and connect to the end of the first lead screw. The X-axis reduction handwheel, through the cooperation of the first lead screw and the axial slide, manually drives the X-axis translation mechanism to translate along the X-axis.

[0009] The axial slide rails are fixed at intervals at both ends of the bottom platform, and the axial slide table is slidably mounted on the axial guide rails.

[0010] The drive device includes a second servo motor and a second reduction handwheel. The second servo motor is mounted on a rotating platform, and a second electromagnetic clutch is also provided between the second servo motor and the worm gear. The second electromagnetic clutch is mounted on the rotating platform. When the power is not interrupted, the second reduction handwheel rotates backward and disengages from the worm gear, while the second servo motor directly drives the worm gear, causing the Z-axis rotation mechanism to rotate. When the power is off, the second electromagnetic clutch disconnects the second servo motor from the worm gear. The second reduction handwheel is manually operated to connect forward to the end of the worm gear. The second reduction handwheel is then manually operated to drive the Z-axis rotation mechanism to achieve rotational motion.

[0011] The worm gear is mounted on a rotating platform, with one end connected to the second reduction handwheel and the other end connected to the second lead screw drive. The rotating platform is also equipped with a rotating platform guide rail, a rotating platform slide mounted on the rotating platform guide rail, and a power rack mounted on the rotating platform slide. The tail of the power rack is connected to the second lead screw, and the worm gear and the second lead screw provide linear thrust to drive the ring gear disk to rotate.

[0012] The optical platform includes an upper panel and a lower panel, and a support tube fixed between the two. A level is mounted on the support tube, and the lower panel is fixedly connected to a ring gear disk.

[0013] The base and the bottom platform are fixed by a first rigid connecting plate, and the rigid connecting plate is provided with an elongated waist-shaped hole. The base and the bottom platform are provided with threaded holes at corresponding positions, and the three are fixedly connected by the provided bolts. The bottom platform and the optical platform are fixed together by a second rigid connecting plate, which also has an elongated waist-shaped hole. The bottom platform and the optical platform have threaded holes at corresponding positions, and the three are fixedly connected by bolts.

[0014] The annular gear disk and the optical platform are respectively provided with threaded holes at corresponding positions and are fixedly connected by bolts.

[0015] The leveling outrigger is also equipped with a vibration isolator at its end.

[0016] The beneficial effects of this invention are: (1) The vehicle-mounted two-degree-of-freedom optical platform is equipped with an X-axis translation mechanism, a Z-axis rotation mechanism and an optical platform arranged on the bottom platform above the base. The X-axis translation mechanism can drive the Z-axis rotation mechanism and the optical platform to translate on the bottom platform, and the Z-axis rotation mechanism can drive the optical platform to rotate. It can realize the two-degree-of-freedom adjustable function of the optical platform, can work efficiently in a limited environment, and provide two-degree-of-freedom motion to simulate the attitude change of optical equipment in actual applications. At the same time, it has a compact structure and is easy to install, which meets the testing function of vehicle-mounted container optical equipment.

[0017] (2) The base is fixedly connected to the vehicle platform base plate. During use, the leveling legs are adjusted to provide rigid support, and the optical platform is adjusted to be horizontal according to the level. The X-axis translation mechanism has the ability to translate the optical platform on the base with the Z-axis rotation mechanism. The Z-axis rotation mechanism has the ability to rotate the optical platform, realizing the two-degree-of-freedom adjustable function of the optical platform. The vehicle-mounted two-degree-of-freedom optical platform can also manually realize the X-axis translation and Z-axis rotation functions through the electromagnetic clutch and handwheel when the power is off.

[0018] (3) During the vehicle movement, the vehicle-mounted two-degree-of-freedom optical platform can retract the leveling legs and achieve a fixed connection between the base and the Z-axis rotation mechanism, the Z-axis rotation mechanism and the optical platform through two rigid connecting plates, thereby achieving self-locking during the movement of the vehicle platform.

[0019] (4) The vibration isolators installed at the base table legs can effectively isolate vibration, eliminate resonance hazards and increase the stability of the vehicle-mounted two-degree-of-freedom optical platform during the movement of the vehicle platform; while the hanging rings installed on the base are used to fix it to the vehicle platform to prevent the vehicle-mounted two-degree-of-freedom optical platform from tilting.

[0023] This invention provides a vehicle-mounted two-degree-of-freedom optical platform, such as... Figures 1 to 6 As shown.

[0024] A vehicle-mounted two-degree-of-freedom optical platform includes a base (1) fixed on the bottom plate of a container, an X-axis translation mechanism (2), a Z-axis rotation mechanism (3) and an optical platform (4) located on a bottom platform above the base. The X-axis translation mechanism can drive the Z-axis rotation mechanism and the optical platform to translate on the bottom platform, and the Z-axis rotation mechanism can drive the optical platform to rotate.

[0025] The base is provided with a vertically adjustable leveling support leg (103). The X-axis translation mechanism includes an axial slide rail arranged on the bottom platform, an axial slide table slidably arranged on the axial slide rail, and a drive slide table arranged in the middle. The upper end of the axial slide table is fixedly connected to the rotating platform of the Z-axis rotation mechanism. The drive slide table drives the rotating platform to translate. The Z-axis rotation mechanism (3) includes an annular gear disk fixed on the rotating platform, a second lead screw meshing with it, and a worm gear, and drives the annular gear disk to rotate under the action of the equipped drive device.

[0026] The axial slide is driven to move back and forth under the action of the independently configured first servo motor (when powered on) and the X-axis reduction handwheel (when powered off). A first electromagnetic clutch is configured between the first servo motor and the first lead screw. The first lead screw is mounted on a bearing fixed on the bottom platform.

[0027] When the power is not interrupted, the first servo motor directly drives the first lead screw and the axial slide to move the X-axis translation mechanism along the X-axis; at this time, the X-axis reduction handwheel can rotate backward, disengaging from the first lead screw, and will not rotate along with it.

[0028] When the power is off, the first electromagnetic clutch disconnects the first servo motor from the first lead screw (power mechanism). The X-axis reduction handwheel is manually operated to move forward and connect to the end of the first lead screw. The X-axis reduction handwheel is manually driven through the first lead screw and the axial slide table, allowing the X-axis translation mechanism to move along the X-axis.

[0029] The drive device includes a second servo motor and a second reduction handwheel. The second servo motor is mounted on a rotating platform, and a second electromagnetic clutch is also provided between the second servo motor and the worm gear. The second electromagnetic clutch is mounted on the rotating platform. When the power is not interrupted, the second servo motor directly drives the worm gear, which in turn drives the Z-axis rotation mechanism to achieve rotational motion. At this time, the second reduction handwheel can rotate backward, disengaging from the worm gear and not rotating along with it.

[0030] When power is off, the second electromagnetic clutch disconnects the second servo motor from the worm gear. The second reduction handwheel is then manually operated to connect forward to the end of the worm gear, driving the Z-axis rotation mechanism to achieve rotational motion.

[0031] The worm gear (303) is mounted on the rotating platform (311). One end of the worm gear is connected to the second reduction handwheel, and the other end is connected to the second lead screw (305) for transmission. The rotating platform (311) is also equipped with a rotating platform guide rail, a rotating platform slide mounted on the rotating platform guide rail, and a power rack mounted on the rotating platform slide. The tail of the power rack is connected to a second lead screw, and a worm gear and the second lead screw provide linear thrust to drive the ring gear disk to rotate. In the event of a power outage, this vehicle-mounted two-degree-of-freedom optical platform can be manually rotated via an electromagnetic clutch and a reduction handwheel to achieve X-axis translation and rotation functions.

[0032] The optical platform (4) includes an upper panel and a lower panel, and a square tube fixed between the two. A level is provided on the square tube, and the lower panel is fixedly connected to the ring gear disk.

[0033] The leveling support leg (103) is also equipped with a vibration isolator (102) at its end. The vibration isolator is free of resonance peaks and can effectively isolate vibration, eliminate resonance hazards, and increase the stability of the vehicle-mounted two-degree-of-freedom optical platform during the movement of the vehicle platform.

[0034] The annular gear disk (310) and the optical platform are respectively provided with threaded holes and are fixedly connected by bolts.

[0035] When the two-degree-of-freedom platform is not in operation, the base and the bottom platform are fixed together by a first rigid connecting plate, which has an elongated, waist-shaped hole. Corresponding threaded holes are provided on the base and the bottom platform, and the three are fixedly connected by bolts. The bottom platform and the optical platform are fixed together by a second rigid connecting plate, which also has an elongated, waist-shaped hole. Corresponding threaded holes are provided on the bottom platform and the optical platform, and the three are fixedly connected by bolts. At this time, the leveling legs are in the retracted state, and the vibration isolators provide support, filtering out upper and lower loads. The lifting ring and the vehicle platform are fixedly connected, effectively isolating vibrations during transportation.

[0036] When the two-degree-of-freedom platform is working, lower the leveling legs and adjust the optical platform to be level using a level indicator.

[0037] The following detailed description is provided in conjunction with specific embodiments: The base (1) includes a drawer (101), a vibration isolator (102), a leveling leg (103), a lifting ring (104), a square tube (105), and a base panel (106); the square tube (105) forms the frame of the base, providing support for the X-axis translation mechanism (2), the Z-axis rotation mechanism (3), and the optical platform (4), and is used for connection with the container; the vibration isolator (102) is fixedly connected to the table legs of the base (1), playing a role in eliminating resonance hazards and improving the stability of the optical platform; the leveling leg (103) The base (1) is fixedly connected to the base, which can adjust the optical platform (4) and provide rigid support; the drawer (101) is fixedly connected to the side of the square tube (105), and the drawer is convenient for placing tools, adjustment handles, pads and other tools; the base panel (106) is fixedly connected to the square tube (105), and the base panel is used to fix the bottom platform (211) to provide support; the lifting ring (104) is fixedly connected to the side of the square tube (105), and the lifting ring is used to fix it to the vehicle wall during transportation to prevent tilting.

[0038] like Figure 3As shown, the X-axis translation mechanism (2) includes a first servo motor (201), a first electromagnetic clutch (202), a bearing (203), a drive slide (204), a first lead screw (205), an X-axis reduction handwheel (206), an axial slide (207), an axial guide rail (208), a control box (209), a control box mounting plate (210), and a bottom platform (211). The first servo motor (201) is mounted on the bottom platform (211) and is used to provide power to the X-axis translation mechanism (2), allowing it to reciprocate. The first electromagnetic clutch (202) is mounted on the bottom platform (211) and is used to disconnect the connection between the first servo motor and the first lead screw when the power is off, allowing it to be manually operated via the X-axis reduction handwheel (206) to make the X-axis translation mechanism (2) translate along the X-axis. The bearing (203) is mounted on the bottom platform (211) and provides support for the first lead screw (205).

[0039] The drive slide (204) works in conjunction with the first lead screw (205) to convert the rotational motion into precise linear motion, achieving precise positioning and micro-feeding. It is fixedly connected to the rotary platform and carries the Z-axis rotation mechanism (3) and the optical platform (4) to achieve X-axis translational motion. The X-axis reduction handwheel (206) is installed on the bottom platform (211). When the power is off, the X-axis reduction handwheel (206) can be manually operated to drive the first lead screw (205) to achieve X-axis translational motion.

[0040] In this embodiment, two axial guide rails (208) are provided and fixedly connected to the bottom platform (211); four axial slides (207) are correspondingly and freely slidably installed on the axial guide rails (208). The upper side of the axial slides (207) is fixedly connected to the rotating platform (311). When the drive slide (204) moves the rotating platform (311) to achieve X-axis translation, the axial slides (207) play a supporting and assisting role in sliding. The bottom platform (211) is fixedly connected to the base panel (106). The control box mounting plate (210) is installed on the bottom platform (211), and the control box (209) is installed on the control box mounting plate (210). The control box can be moved by the control mechanism via a handle.

[0041] like Figure 4As shown, the Z-axis rotation mechanism includes a second servo motor (301), a second electromagnetic clutch (302), a worm gear (303), a second reduction handwheel (304), a second lead screw (305), a power rack (306), a rotary platform slide (307), a rotary platform guide rail (308), a ring gear base (309), a ring gear disk (310), and a rotary platform (311). The second servo motor (301) is mounted on the rotary platform (311) and provides power for its rotation. The second electromagnetic clutch (302) is installed on the rotating platform (310) to disconnect the worm gear from the second servo motor when the power is off, so that it can be manually operated through the second reduction handwheel (304) to make the Z-axis rotating mechanism (3) rotate. The worm gear (303) is also installed on the rotating platform (310), and one end of the worm gear (303) is connected to the second reduction handwheel (304) to provide conditions for its manual operation. The second reduction handwheel (304) is installed on the rotating platform (310), and when the power is off, the second lead screw (305) can be driven to rotate by manually operating the second reduction handwheel (304) of the rotating platform. The second lead screw (305) works with the worm gear (303) to convert the rotational motion into precise linear motion, realize precise positioning and micro-feed, and at the same time amplify the torque to generate a large linear thrust.

[0042] The power rack (306) is mounted on the rotary platform slide (307), and the other end is connected to the second lead screw (305). The worm gear (303) cooperates with the second lead screw (305) to provide linear thrust, and achieves linear motion under the auxiliary sliding action of the rotary platform slide (307). The rotary platform slide (307) is mounted on the rotary platform guide rail (308) to provide support and auxiliary sliding action for the sliding of the power rack (306). The ring gear disk base (309) is mounted on the rotary platform (311) to provide support for the ring gear disk (310). The ring gear disk (310) is mounted on the ring gear disk base (309) and cooperates with the power rack (306) to convert the linear motion of the power rack into rotational motion. The upper side is fixedly connected to the optical platform (4) and rotates together with the optical platform (4).

[0043] like Figure 5 As shown, the optical platform (4) consists of an upper panel (401), a lower panel (402), a support tube (403), and a level (404). The upper panel (401) is fixedly connected to the support tube (403), the lower panel (402) is fixedly connected to the support tube (403), and the other side is fixedly connected to the ring gear disk (309). The level (404) is fixedly connected to the support tube (403) to facilitate the leveling of the optical platform (4).

[0044] In this example, the specific connection method can be welding, bolting, or other methods commonly used in this field, and no specific restrictions are imposed here.

[0045] When the power is not interrupted, the X-axis translation and rotation can be achieved through the handle inside the control box.

[0046] When the X-axis translational motion command is issued, the first servo motor (201) starts working, driving the first lead screw (205) to move. The drive slide (204) cooperates with the first lead screw (205) to convert the rotational motion into precise linear motion. The drive slide (204) is fixedly connected to the Z-axis rotation mechanism (3), and together with the Z-axis rotation mechanism (3) and the optical platform (4), it realizes the X-axis translational reciprocating motion. At this time, the X-axis reduction handwheel can rotate backward, disengaging from the first lead screw, and will not move with it.

[0047] When the Z-axis rotation command is issued, the second servo motor (301) starts working. Passing through the worm gear (303), the worm gear (303) converts the high-speed rotation of the second servo motor (301) of the rotary platform into a low-speed rotation, increasing the output torque to drive the rotary platform's lead screw. The second lead screw (305) is connected to the rotary platform's worm gear (303), converting the rotational motion into precise linear motion. The power rack (306) is mounted on the rotary platform's slide (307), with its other end connected to the second lead screw (305). The second lead screw (305) provides linear thrust, achieving linear motion with the assistance of the rotary platform's slide (307). The power rack (306) cooperates with the ring gear disk (310), converting the linear motion of the power rack into rotational motion, driving the optical platform (4) to rotate together, achieving a reciprocating rotation function. At this time, the second reduction handwheel can rotate backward, disengaging from the worm gear and not moving with it.

[0048] When the power is off, the connection between the transmission mechanism and the servo motor can be disconnected by the electromagnetic clutch, and the X-axis translational motion and Z-axis rotational motion can be achieved by manual operation of the handwheel.

[0049] When the power is off, the first electromagnetic clutch (202) disconnects the servo motor from the first lead screw. The X-axis reduction handwheel is manually operated to connect forward to the end of the first lead screw. The reduction handwheel (206) is manually operated to drive the first lead screw (205) to move. The drive slide (204) cooperates with the first lead screw (205) to convert the rotational motion into precise linear motion. The drive slide (204) is fixedly connected to the Z-axis rotation mechanism (3), and the Z-axis rotation mechanism (3) and the optical platform (4) realize the X-axis translational reciprocating motion.

[0050] When the power is off, the second electromagnetic clutch (302) disconnects the servo motor from the worm gear. The second reduction handwheel is manually operated to connect to the end of the worm gear, and the second reduction handwheel (304) is manually operated to drive the second lead screw (305) to move. The second lead screw (305) converts the rotational motion into precise linear motion. The power rack (306) is mounted on the rotary platform slide (307), and the other end is connected to the second lead screw (305). The second lead screw (305) provides linear thrust, and linear motion is achieved with the assistance of the rotary platform slide (307). The power rack (306) cooperates with the ring gear disk (310) to convert the linear motion of the power rack into rotational motion, driving the optical platform (4) to rotate together, realizing the rotational reciprocating function.

[0051] The X-axis translation mechanism (2) and the Z-axis rotation mechanism (3) are two-layer structures. The translation function of the X-axis translation mechanism (2) and the rotation function of the Z-axis rotation mechanism (3) can be used simultaneously without interfering with each other.

[0052] like Figure 6 As shown, when the two-degree-of-freedom platform is not working, the base (1) and the Z-axis rotation mechanism (3) are fixed by the first rigid connecting plate (5). The first rigid connecting plate (5) has an elongated waist-shaped hole, and the base (1) and the Z-axis rotation mechanism (3) are provided with threaded holes at corresponding positions, and the three are fixedly connected by bolts.

[0053] The Z-axis rotation mechanism (3) and the optical platform (4) are fixed by a second rigid connecting plate (6). The second rigid connecting plate (6) has an elongated waist-shaped hole, and the Z-axis rotation mechanism (3) and the optical platform (4) are provided with threaded holes at corresponding positions. The three are fixedly connected by bolts, thereby realizing the self-locking function during the movement of the vehicle platform.

[0054] At this time, the leveling outrigger (103) is in the retracted state, and the vibration isolator (102) is a vibration isolator without resonance peak, which provides support. The vibration isolator can filter out the upper and lower loads and isolate the resonance hazards. The lifting ring (105) is fixedly connected to the vehicle platform, which can effectively isolate the vibration during transportation and prevent tilting.

[0055] When the two-degree-of-freedom platform is working, the leveling outrigger (103) is lowered to provide rigid support, and the optical platform (4) is adjusted to be level according to the level (404).
