Technical Field

[0001] This utility model relates to the field of tracking servo turntable technology, specifically a tracking servo turntable with high airtightness. Background Technology

[0002] Servo rotary tables, through high-precision mechatronics design, have become key equipment in modern industry, scientific research, and national defense. Their performance parameters (such as angular position measurement resolution) and applicable scenarios vary significantly, and selection should be based on specific needs, for example;

[0003] Authorized announcement number CN216463806U provides a servo rotary table, including a housing. A movable rod is movably connected to the inner surface of the housing, and a first worm gear is fixedly connected to the outer surface of the movable rod. A motor is fixedly connected to the inner bottom surface of the housing, and a second worm gear is fixedly connected to the output end of the motor. The first worm gear meshes with the second worm gear. A cylinder is fixedly connected to the upper surface of the movable rod, and a disc is fixedly connected to the upper surface of the cylinder. A first sliding groove is fixedly connected to the upper surface of the disc, and a cross is slidably connected to the inner surface of the first sliding groove. A movable strip is movably connected to the upper surface of the cross. This invention, by incorporating a motor, when the motor starts working, will drive a series of interconnected structures, causing the entire rotary table to rotate while briefly pausing. This allows time for polishing of the metal parts, resulting in a smoother finish.

[0004] However, existing tracking servo turntables do not have an effective sealing structure inside the device, which makes it easy for foreign objects on the outside of the device to enter the device through the connection gaps. This can affect the operating accuracy of the device.

[0005] Therefore, to address the aforementioned issues, there is an urgent need for innovative design based on the existing tracking servo turntable. Utility Model Content

[0006] The purpose of this invention is to provide a tracking servo turntable with high airtightness to solve the problem mentioned in the background art that the lack of an effective sealing structure inside the device makes it easy for foreign objects from the outside of the device to enter the device through the connection gaps, which in turn affects the operating accuracy of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tracking servo turntable with high airtightness, comprising: a mounting base, and a support frame connected to the upper side of the mounting base, wherein a support platform is installed inside the support frame;

[0008] Also includes:

[0009] A first drive motor is installed inside the mounting base, and a first drive disk is connected to the upper side of the first drive motor. A transmission disk is provided on the outer side of the first drive disk. A positioning block is provided on the outer side of the mounting base, and a scale is connected to the upper side of the positioning block. A connecting tooth is provided in the middle of the lower end of the support frame, and a guide ring is provided on the outer side of the lower end of the support frame. A first sealing ring is installed on the lower side of the guide ring, and a second sealing ring is installed on the outer side of the guide ring.

[0010] The second limiting rod is installed on the outside of the support platform, and the support platform is equipped with a spacing adjustment component. A clamping plate is provided on the upper side of the support platform, and a clamping adjustment component is installed on the outside of the clamping plate. A connecting block is connected to the lower side of the clamping plate, and a guide strip is connected to the outside of the connecting block.

[0011] In one possible implementation, the positioning block is engaged with the dial, and the positioning block is symmetrically arranged about the central axis of the mounting base.

[0012] In one possible implementation, the transmission disc is engaged with both the first drive disc and the connecting teeth, and the transmission disc is rotatably connected to the mounting base.

[0013] In one possible implementation, the guide ring is rotatably connected to the mounting base, and the second sealing ring is engaged with the guide ring.

[0014] In one possible implementation, the spacing adjustment assembly includes a second drive motor installed inside the support platform, and a second drive disk is connected to the front end of the second drive motor. A drive rod is provided at the front end of the second drive disk, and a third drive disk is installed in the middle of the drive rod.

[0015] The second drive disc and the third drive disc are engaged with each other, and the drive rod and the third drive disc are rotatably connected to the support platform.

[0016] In one possible implementation, the drive rod is threadedly connected to the connecting block, and the threads at the left and right ends of the drive rod are arranged in opposite directions.

[0017] In one possible implementation, the clamping adjustment assembly includes a wrapping plate mounted on the outside of the clamping plate, and a guide rod connected to the inside of the wrapping plate, wherein a damper is provided in the middle of the guide rod;

[0018] The guide rod is slidably connected to the clamping plate, and the guide rod is symmetrically arranged about the central axis of the clamping plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This highly airtight tracking servo turntable has an effective sealing structure inside the device, making it difficult for foreign objects from the outside to enter the device through the connection gaps. This avoids the situation where foreign objects entering the device can affect the operating accuracy. At the same time, it is easy to adjust the clamping distance of the device during use, allowing the device to adjust its clamping distance in a timely manner according to different usage conditions, thereby improving the efficiency of the device and achieving better performance. Specific details are as follows:

[0020] 1. The second drive motor, in conjunction with the second drive disc, drives the drive rod and the third drive disc to rotate inside the support platform. This allows the drive rod to effectively push the connecting block to move inward along the guide bar. At this time, the connecting block drives the clamping plate connected to its upper side to effectively clamp and limit the instrument placed on the upper side of the support platform, preventing the instrument from shaking and falling off due to centrifugal force during the rotation of the device, thus improving the stability of the device.

[0021] 2. The damper, in conjunction with the guide rod, pushes the wrapping plate to move inward toward the clamping plate, so that the guide rod drives the wrapping plate to wrap and clamp the instrument. This facilitates the device to wrap and limit the instrument from multiple directions, preventing the instrument from falling out of the device and improving the safety of the device.

[0022] 3. The connection gap between the guide ring and the mounting base is filled and sealed by the first sealing ring and the second sealing ring. This prevents impurities and dust from the external environment from entering the interior of the mounting base through the connection gap between the guide ring and the mounting base when the device is idle. This avoids impurities from corroding the first drive plate and the transmission plate, reducing their accuracy, and improving the device's performance. Attached Figure Description

[0030] 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.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a tracking servo turntable with high airtightness, including a mounting base 1, a positioning block 2, a scale dial 3, a first drive motor 4, a first drive disk 5, a transmission disk 6, a support frame 7, connecting teeth 8, a guide ring 9, a first sealing ring 10, a second sealing ring 11, a pointer 12, a first limiting rod 13, a support platform 14, a second limiting rod 15, a second drive motor 16, a second drive disk 17, a drive rod 18, a third drive disk 19, a connecting block 20, a guide strip 21, a clamping plate 22, a wrapping plate 23, a guide rod 24, and a damper 25.

[0032] Specifically, such as Figure 4 , Figure 5 and Figure 6As shown, before using the device, the support platform 14 is installed on the upper side of the support frame 7. Then, the second limiting rod 15, which passes through the outer side of the support platform 14, is rotated. Due to the threaded connection between the second limiting rod 15 and the support frame 7 and support platform 14, the inward rotation of the second limiting rod 15 effectively fixes the support platform 14 inside the support frame 7. Simultaneously, the instrument to be tested is placed on the upper side of the support platform 14. Then, the second drive motor 16 installed inside the support platform 14 is activated, causing the second drive motor 16 to drive the second drive disc 17 connected to its front end to rotate inside the support platform 14. As the second drive disc 17 and the third drive disc 19 rotate, the second drive disc 17 can effectively push the drive rod 18 and the third drive disc 19 to rotate inside the support platform 14. At this time, due to the threaded connection between the drive rod 18 and the connecting block 20, the rotating drive rod 18 can effectively drive the drive rod 18 connected to its outer side to move inward. Because of the opposing threaded structures at the left and right ends of the drive rod 18, the drive rod 18 can synchronously drive the connecting blocks 20 on its left and right sides to move inward simultaneously. The sliding connection structure between block 20 and guide bar 21 allows the inward displacement of connecting block 20 to be guided and limited by guide bar 21, facilitating positional shift of connecting block 20 during inward displacement. At this time, connecting block 20 drives the clamping plate 22 connected to its upper side to shift inward, effectively clamping and limiting the instrument placed on the support platform 14, preventing the instrument from shaking and falling off due to centrifugal force during rotation, thus improving the stability of the device. Simultaneously, during the clamping and limiting of the instrument by clamping plate 22, the wrapping plate 23 is pulled outward, and due to the guide bar 2... The sliding connection structure between the 4 and the clamping plate 22 allows the pulled wrapping plate 23 to move outward along the guide rod 24 connected to its inner side, compressing the damper 25 to ensure that the wrapping plate 23 cooperates with the clamping plate 22 to wrap the instrument. At this time, releasing the pull on the wrapping plate 23 causes the compressed damper 25 to generate a rebound reaction force, driving the guide rod 24 to reset inward along the clamping plate 22. At this time, the guide rod 24 drives the wrapping plate 23 to wrap and clamp the instrument, thereby completing the multi-directional wrapping and limiting work of the instrument, preventing the instrument from falling out of the device and improving the safety of the device.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, during the use of the device, the dial 3 is installed on the outside of the mounting base 1 by installing the positioning block 2 along the outside of the mounting base 1. At this time, due to the engaging connection structure between the positioning block 2 and the dial 3, the positioning block 2 can initially fix the dial 3 on the outside of the mounting base 1. Then, the pointer 12 is installed at the front end of the support frame 7, and the first limiting rod 13 is pressed inward. Due to the engaging connection structure between the first limiting rod 13, the pointer 12, and the support frame 7, the first limiting rod 13, which is pressed and displaced backward, connects the pointer 12 and the support frame 7 in series. At this time, the first drive motor 4 installed inside the mounting base 1 is started, causing the first drive motor 4 to drive the first drive disk 5 connected to its upper side to rotate on the upper side of the mounting base 1. Due to the meshing connection structure between the transmission disk 6, the first drive motor 4, and the connecting teeth 8, the first drive disk 5 can effectively push the transmission disk 6 to rotate on the lower side of the support frame 7 during the rotation. Driven by the transmission disc 6, the support frame 7 rotates on the upper side of the mounting base 1. This causes the pointer 12 mounted at its front end to rotate on the upper side of the mounting base 1, allowing the operator to determine the rotation angle of the turntable based on the positional relationship between the pointer 12 and the scale 3. Simultaneously, the rotation of the support frame 7 effectively drives the guide ring 9 to rotate inside the mounting base 1. Since the guide ring 9 is equipped with a first sealing ring 10 and a second sealing ring 11, the first sealing ring 10, in conjunction with the second sealing ring 11, effectively seals the connection between the guide ring 9 and the mounting base 1 during rotation. This prevents dust or impurities from entering the interior of the first drive disc 5 through the gap between the guide ring 9 and the mounting base 1, thus preventing impurities from corroding the first drive disc 5 and the transmission disc 6 and reducing their accuracy, thereby improving the overall performance of the device.
