Description

Technical Field

[0001] This utility model relates to the field of three-axis positioning platform technology, and in particular to an adjustable three-axis positioning platform. Background Technology

[0002] A three-axis positioning platform, also known as a three-axis positioning instrument or a three-axis stabilizing platform, is an instrument used to measure and control the position and orientation of an object in three directions.

[0003] When using a three-axis positioning platform to place and adjust objects, the object is usually placed on the platform plate. Then, depending on the actual usage requirements, the drive mechanism inside the base is activated to move the longitudinal adjustment frame back and forth on the base. At the same time, the drive mechanism inside the longitudinal adjustment frame can also be activated to move the transverse adjustment frame left and right on the longitudinal adjustment frame. Then, as needed, the drive mechanism in the transverse adjustment frame is activated to rotate the turntable and the platform plate to adjust the position of the object for processing. Since the object is usually placed directly on the platform plate or fixed to the platform plate with several bolts, placing it directly on the platform plate may cause shaking during adjustment and processing, resulting in displacement of the object and making it inconvenient for processing. Fixing it with bolts for limiting and fixing means that when picking up or replacing the object, several bolts must be unscrewed first, and then the replaced object must be placed on the platform plate and tightened again with bolts. This makes the disassembly and installation steps numerous and cumbersome, inconvenient for replacement and use, and reduces the practicality of the three-axis positioning platform. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable three-axis positioning platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable three-axis positioning platform, including a base, a longitudinal adjustment frame slidably connected to one side of the base, a transverse adjustment frame slidably connected to one side of the longitudinal adjustment frame, a turntable rotatably connected to one side of the transverse adjustment frame, a platform plate fixedly connected to one side of the turntable, and a limiting device provided on one side of the platform plate. The limiting device can limit and fix objects of different sizes placed on the platform plate, while facilitating the replacement of objects and improving the practicality of the three-axis positioning platform.

[0006] The effect achieved by the above components is as follows: When using a three-axis positioning platform to place and adjust an object, the object is usually placed on the platform plate, and then fixed and limited by a limiting device. Finally, according to the actual use requirements, the drive mechanism inside the base is activated to drive the longitudinal adjustment frame to slide back and forth on the base. At the same time, the drive mechanism inside the longitudinal adjustment frame can also be activated to drive the transverse adjustment frame to move left and right on the longitudinal adjustment frame. Then, according to the requirements, the drive mechanism in the transverse adjustment frame is activated to drive the turntable and the platform plate to rotate and adjust the position of the object, which facilitates its processing.

[0007] Preferably, the limiting device includes two limiting plates. A first sliding groove is provided on one side of the platform plate, and second sliding grooves are symmetrically provided at both ends of the platform plate. One end of each limiting plate is slidably connected to the inner wall of the first and second sliding grooves. A spring is fixedly connected to one side of the inner wall of the second sliding groove, and one end of the spring is fixedly connected to one side of the limiting plate. A pull rope is fixedly connected to one side of the limiting plate. A round rod is passed through the inner wall of the first sliding groove, and a motor is fixedly connected to one end of the round rod. The motor is a self-locking motor, and one side of the motor is fixedly connected to one side of the platform plate.

[0008] The aforementioned components achieve the following effects: By setting a limiting device, when an object is placed on the platform for processing, the motor can be started to drive the round rod to rotate in the inner wall of the first slide groove, and then the two pull ropes are wound up, pulling the limiting plates to slide in opposite directions in the inner walls of the first and second slide grooves, so that the springs are compressed, and then the two sides of the placed object are clamped and limited. In this way, the object is less likely to shake or shift during adjustment. At the same time, when it is necessary to replace the object for processing, the motor only needs to be reversed to release the winding of the pull ropes, and then under the reset action of the springs, the two limiting plates can be pushed to both ends to open and release the limits, which facilitates the replacement of the object and improves the practicality of the three-axis positioning platform.

[0009] Preferably, a telescopic rod is fixedly connected to one side of the inner wall of the second slide groove, one end of the telescopic rod is fixedly connected to one side of the limiting plate, and the telescopic rod is sleeved with a spring.

[0010] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use and increasing its service life.

[0011] Preferably, a plurality of anti-slip strips are fixedly connected to one side of the limiting plate, and the plurality of anti-slip strips are arranged at equal intervals.

[0012] The effect achieved by the above components is that by setting anti-slip strips, the contact friction on one side of the limiting plate can be increased, making it more secure and stable when clamping and holding objects.

[0013] Preferably, a plurality of limiting blocks are fixedly connected to the outer surface of the round rod, the pull rope is disposed between two adjacent limiting blocks, and the limiting blocks are disposed in the inner wall of the first sliding groove.

[0014] The effect achieved by the above components is that by setting a limit block, the two pull ropes can be separated, making them less prone to knotting during winding and improving their service life.

[0015] Preferably, a protective mechanism is provided on one side of the platform plate. The protective mechanism includes a threaded protective cover. A threaded ring block is fixedly connected to one side of the platform plate. The inner wall of one end of the threaded protective cover is threadedly connected to the outer surface of the threaded ring block. The motor is disposed in the inner wall of the threaded ring block and the threaded protective cover.

[0016] The effect achieved by the above components is as follows: by setting up a protective mechanism, the threaded protective cover can cover the outer surface of the motor and be screwed and fixed on the outer surface of the threaded ring block, so that the motor is not easily hit during use, avoiding damage to the motor and improving the service life of the motor.

[0017] Preferably, auxiliary devices are provided on both sides of the platform plate. The auxiliary devices include expansion plates. The bottom ends of the platform plate are symmetrically provided with slots. The two ends of the platform plate are symmetrically rotatably connected with limit rods. A locking block is symmetrically fixedly connected to one side of the expansion plate. The locking block is inserted into the inner wall of the slot.

[0018] The effect achieved by the above-mentioned components is as follows: By setting up the auxiliary device, when the placement area of ​​the platform board is insufficient, the expansion board can be manually held and the two locking blocks on one side can be respectively locked into the two locking slots on one end of the platform board. Then, the limiting rod can be rotated to a certain angle so that one side of it abuts against one side of the locking block, thus limiting it in the locking slot. In this way, the expansion board can be fixed and limited on the platform board, expanding the placement area of ​​the platform board and making it easier to use.

[0019] Preferably, a magnet is fixedly connected to one side of the card block, the limiting rod is made of iron, and one side of the magnet is magnetically attracted to one side of the limiting rod.

[0020] The effect achieved by the above components is as follows: by setting a magnet, when the limiting rod abuts against the card block to limit and fix it, the magnet can fix and attract the limiting rod, making it difficult for it to slide away, and the limiting is more secure.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a limiting device, when an object is placed on the platform for processing, the motor can be started to drive the round rod to rotate in the inner wall of the first slide groove, and then the two pull ropes are wound up, pulling the limiting plates to slide in opposite directions in the inner walls of the first and second slide grooves, so that the springs are compressed, and then the two sides of the placed object are clamped and limited. In this way, the object is not easy to shake or shift during adjustment. At the same time, when it is necessary to replace the object for processing, the motor only needs to be reversed to release the winding of the pull ropes. Then, under the reset action of the springs, the two limiting plates can be pushed to both ends to open and release the limits, which facilitates the replacement of the object. This makes the operation convenient and improves the practicality of the three-axis positioning platform. Attached Figure Description

Detailed Implementation

[0030] Example 1, as Figure 1-6As shown, an adjustable three-axis positioning platform includes a base 1. A longitudinal adjustment frame 4 is slidably connected to one side of the base 1, and a transverse adjustment frame 5 is slidably connected to one side of the longitudinal adjustment frame 4. A turntable 6 is rotatably connected to one side of the transverse adjustment frame 5, and a platform plate 7 is fixedly connected to one side of the turntable 6. A limiting device 2 is provided on one side of the platform plate 7. The limiting device 2 can limit and fix objects of different sizes placed on the platform plate 7, and at the same time facilitate the replacement of objects, improving the practicality of the three-axis positioning platform. When using the three-axis positioning platform to place and adjust objects, the object is usually placed on the platform plate 7, and then fixed and limited by the limiting device 2. Finally, according to the actual use requirements, the drive mechanism inside the base 1 is activated to drive the longitudinal adjustment frame 4 to slide back and forth on the base 1. At the same time, the drive mechanism inside the longitudinal adjustment frame 4 can be activated to drive the transverse adjustment frame 5 to move left and right on the longitudinal adjustment frame 4. Then, according to the needs, the drive mechanism in the transverse adjustment frame 5 is activated to drive the turntable 6 and the platform plate 7 to rotate and adjust the position of the object, facilitating its processing.

[0031] Reference Figure 2-4As shown, this embodiment discloses a limiting device 2 including two limiting plates 23. A first sliding groove 21 is provided on one side of the platform plate 7, and a second sliding groove 22 is symmetrically provided at both ends of the platform plate 7. One end of each limiting plate 23 is slidably connected to the inner wall of the first sliding groove 21 and the second sliding groove 22. A spring 24 is fixedly connected to one side of the inner wall of the second sliding groove 22. One end of the spring 24 is fixedly connected to one side of the limiting plate 23. A pull rope 25 is fixedly connected to one side of the limiting plate 23. A round rod 26 is passed through and connected to the inner wall of the first sliding groove 21. A motor 27 is fixedly connected to one end of the round rod 26. The motor 27 is a self-locking motor 27. One side of the motor 27 is fixedly connected to one side of the platform plate 7. By setting the limiting device 2, when an object is placed on the platform plate 7 for processing, the motor 27 can be started to drive the round rod 26 to rotate in the inner wall of the first slide groove 21, and then the two pull ropes 25 are wound up, pulling the limiting plate 23 to slide in opposite directions in the inner walls of the first slide groove 21 and the second slide groove 22, so that the spring 24 is compressed, and then the two sides of the placed object are clamped and limited. In this way, the object is not easy to shake or shift during adjustment. At the same time, when it is necessary to replace the object for processing, the motor 27 only needs to reverse to release the winding of the pull ropes 25, and then under the reset action of the spring 24, the two limiting plates 23 can be pushed to both ends to open and release the limitation, which facilitates the replacement of the object and improves the practicality of the three-axis positioning platform. A telescopic rod 29 is fixedly connected to one side of the inner wall of the second slide groove 22. One end of the telescopic rod 29 is fixedly connected to one side of the limiting plate 23, and the telescopic rod 29 is sleeved and connected to the spring 24. By setting the telescopic rod 29, the inner wall of the spring 24 can be supported and reinforced, making it less prone to damage during use and extending its service life. Several anti-slip strips 210 are fixedly connected to one side of the limiting plate 23, arranged at equal intervals. The anti-slip strips 210 increase the contact friction on one side of the limiting plate 23, making it more secure and stable when clamping an object. Several limiting blocks 211 are fixedly connected to the outer surface of the round rod 26. The pull rope 25 is positioned between two adjacent limiting blocks 211, which are located within the inner wall of the first slide groove 21. The limiting blocks 211 separate the two pull ropes 25, preventing tangling during winding and extending their service life.

[0032] Reference Figure 2-4As shown in the figure, this embodiment discloses a protective mechanism 28 provided on one side of the platform plate 7. The protective mechanism 28 includes a threaded protective cover 282. A threaded ring block 281 is fixedly connected to one side of the platform plate 7. The inner wall of one end of the threaded protective cover 282 is threadedly connected to the outer surface of the threaded ring block 281. The motor 27 is disposed in the inner wall of the threaded ring block 281 and the threaded protective cover 282. By providing the protective mechanism 28, the threaded protective cover 282 can cover the outer surface of the motor 27 and be screwed and fixed to the outer surface of the threaded ring block 281, making it less likely for the motor 27 to be impacted during use, avoiding damage to the motor 27, and improving the service life of the motor 27.

[0033] Reference Figure 5 and Figure 6 As shown in the figure, this embodiment discloses that auxiliary devices 3 are provided on both sides of the platform plate 7. The auxiliary devices 3 include an expansion plate 33. The bottom ends of the platform plate 7 are symmetrically provided with slots 31. The two ends of the platform plate 7 are symmetrically rotatably connected with limiting rods 32. One side of the expansion plate 33 is symmetrically fixedly connected with a locking block 34, which is inserted into the inner wall of the slot 31. According to actual usage needs, when the placement area of ​​the platform plate 7 is insufficient, the expansion plate 33 can be manually held and the two locking blocks 34 on one side can be respectively locked into the two slots 31 on one end of the platform plate 7. Then, the limiting rods 32 can be rotated to a certain angle so that one side of them abuts against the side of the locking block 34, limiting it in the slot 31. Thus, the expansion plate 33 can be fixedly limited on the platform plate 7, expanding the placement area of ​​the platform plate 7 for easy use.

[0034] Reference Figure 5 and Figure 6 As shown, this embodiment discloses a magnet 35 fixedly connected to one side of the locking block 34, and the limiting rod 32 is made of iron. One side of the magnet 35 and one side of the limiting rod 32 are magnetically attracted to each other. By setting the magnet 35, when the limiting rod 32 abuts against the locking block 34 to limit and fix it, the magnet 35 can fix and attract the limiting rod 32, making it difficult for it to slide or move away, and the limiting is more secure.

[0035] Working principle: When using the three-axis positioning platform to place and adjust an object, the object is usually placed on the platform plate 7. The motor 27 is started, causing the round rod 26 to rotate within the inner wall of the first slide groove 21. This winds up the two pull ropes 25, pulling the limiting plate 23 to slide in opposite directions within the inner walls of the first and second slide grooves 21 and 22. This compresses the spring 24, clamping and limiting the object on both sides. This prevents the object from easily shaking or shifting during adjustment. When it is necessary to replace the object for processing, simply reverse the motor 27 to release the winding of the pull ropes 25. Then, under the reset action of spring 24, the two limiting plates 23 can be pushed to both ends to open and release the limit, making it easier to replace the object and improve the practicality of the three-axis positioning platform. Finally, according to the actual use requirements, the drive mechanism inside the base 1 is activated to drive the longitudinal adjustment frame 4 to slide back and forth on the base 1. At the same time, the drive mechanism inside the longitudinal adjustment frame 4 can be activated to drive the transverse adjustment frame 5 to move left and right on the longitudinal adjustment frame 4. Then, according to the requirements, the drive mechanism in the transverse adjustment frame 5 is activated to drive the turntable 6 and the platform plate 7 to rotate and adjust the position of the object, making it easier to process.

[0036] Depending on actual usage needs, when the placement area of ​​the platform plate 7 is insufficient, the expansion plate 33 can be manually held and its two locking blocks 34 on one side can be respectively locked into the two slots 31 on one end of the platform plate 7. Then, the limiting rod 32 can be rotated to a certain angle so that one side of it abuts against one side of the locking block 34 and is attracted and fixed by the magnet block 35, thus limiting it in the slot 31. In this way, the expansion plate 33 can be fixed and limited on the platform plate 7, expanding the placement area of ​​the platform plate 7 for easy use.
