Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a clamping mechanism for an aircraft target calibration clamp. Background Technology

[0002] The aircraft target calibration clamp locking mechanism is a device used to fix and adjust the aircraft target calibration clamp. The use of the aircraft target calibration clamp locking mechanism can improve the accuracy, efficiency and safety of the target calibration, and it is an indispensable and important component in the aircraft target calibration process.

[0003] Some aircraft calibration fixture locking mechanisms still have some problems. For example, the thickness of the aircraft fixing blocks may vary when using the locking mechanism, making it inconvenient to lock the calibration fixture according to the height of the aircraft fixing blocks. This results in poor flexibility and significant limitations.

[0004] Therefore, we propose an aircraft target calibration clamping mechanism to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an aircraft target calibration clamp locking mechanism to solve the problems mentioned in the background art, such as the inconvenience of locking the target calibration clamp according to the height of the aircraft fixing block, poor flexibility, and significant limitations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aircraft target calibration fixture locking mechanism, comprising a fixing plate, an aircraft target calibration fixture body disposed on the left side of the fixing plate, an aircraft fixing block disposed on the left side of the aircraft target calibration fixture body, a baffle disposed on the right side of the aircraft target calibration fixture body, threaded sleeves fixedly connected to the top of the baffle and the fixing plate near the middle, a bidirectional threaded rod disposed between the threaded sleeves, a rotating block fixedly connected at the middle position of the outer side of the bidirectional threaded rod, and threaded grooves machined inside the threaded sleeves.

[0007] As a further technical solution of this utility model, the inside of the threaded groove is machined with internal threads, and the left and right sides of the outside of the bidirectional threaded rod are machined with external threads that cooperate with the internal threads.

[0008] As a further technical solution of this utility model, the threads on the left and right sides of the bidirectional threaded rod are opposite, the bidirectional threaded rod and the threaded groove cooperate with each other, and the left and right sides of the bidirectional threaded rod are installed inside the threaded sleeve through the threaded groove.

[0009] As a further technical solution of this utility model, a locking rod is fixedly connected to the left side of the fixing plate, and a reserved groove is opened in the interior of the aircraft target calibration fixture body and the aircraft fixing block respectively, and a pressing block is fixedly connected to the left side of the locking rod.

[0010] As a further technical solution of this utility model, the locking rod is disposed inside the reserved groove, and the locking rod slides and rotates inside the reserved groove.

[0011] As a further technical solution of this utility model, the upper and lower ends of the left side of the baffle are fixedly connected to limit blocks, and the upper and lower ends of the right side of the aircraft target calibration fixture body are provided with limit slots, and the limit blocks are embedded in the limit slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the aircraft target calibration clamping mechanism not only improves the clamping effect and facilitates the installation of clamping components, but also facilitates the limiting of the baffle.

[0013] (1) By setting up a threaded sleeve, a fixed plate, a double-threaded rod, a rotating block and a threaded groove, the rotating block is rotated, and the rotating block drives the double-threaded rod to rotate inside the threaded groove. Since the threaded groove inside the threaded sleeve and the double-threaded rod cooperate with each other, and the threads outside the double-threaded rod are opposite, the rotation of the double-threaded rod inside the threaded groove can make the threaded sleeve move against the fixed plate, so that the fixed plate pulls the clamping block closer to the aircraft fixed block through the locking rod, so that the clamping block and the baffle can clamp the aircraft fixed block and the aircraft target clamp body, and the clamping of the aircraft target clamp body and the aircraft fixed block can lock the aircraft target clamp body and the aircraft fixed block.

[0014] (2) By setting up a clamping block, a reserved slot and a locking rod, insert the clamping block and the locking rod into the reserved slot. After insertion, push the fixing plate and the baffle to make the locking rod slide inside the reserved slot. After the clamping block slides out of the reserved slot, rotate the baffle to make the locking rod drive the clamping block to rotate. Rotating the clamping block can prevent the clamping block from entering the reserved slot again and affecting the locking of the main body of the aircraft target calibration fixture.

[0015] (3) By setting a limit block and a limit slot, after rotating the clamping block, push the baffle so that the limit block on the left side of the baffle is embedded in the limit slot. Thus, the baffle can be limited by the limit block and the limit slot to prevent the baffle from sliding accidentally. Limiting the baffle can limit the locking rod to prevent the clamping block from being misaligned with the reserved slot and affecting the use. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 The present invention provides an embodiment of an aircraft target calibration clamp locking mechanism, comprising a fixing plate 9, an aircraft target calibration clamp body 1 disposed on the left side of the fixing plate 9, an aircraft fixing block 2 disposed on the left side of the aircraft target calibration clamp body 1, a baffle 10 disposed on the right side of the aircraft target calibration clamp body 1, threaded sleeves 8 being fixedly connected to the baffle 10 and the fixing plate 9 near the middle of the top, a bidirectional threaded rod 11 being disposed between the threaded sleeves 8, a rotating block 12 being fixedly connected at the middle position of the outside of the bidirectional threaded rod 11, and a threaded groove 13 being machined inside the threaded sleeve 8;

[0023] The inside of the threaded groove 13 is machined with internal threads, and the left and right sides of the outside of the bidirectional threaded rod 11 are machined with external threads that mate with the internal threads. The threads on the left and right sides of the outside of the bidirectional threaded rod 11 are opposite. The bidirectional threaded rod 11 and the threaded groove 13 mate with each other, and the left and right sides of the bidirectional threaded rod 11 are installed inside the threaded sleeve 8 through the threaded groove 13.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, rotating the rotating block 12 causes the bidirectional threaded rod 11 to rotate inside the threaded groove 13. Since the threaded groove 13 inside the threaded sleeve 8 and the bidirectional threaded rod 11 are mutually engaged, and the threads outside the bidirectional threaded rod 11 are opposite, the rotation of the bidirectional threaded rod 11 inside the threaded groove 13 can cause the threaded sleeve 8 to move against the fixing plate 9, so that the fixing plate 9 can pull the clamping block 3 closer to the aircraft fixing block 2 through the locking rod 5. Thus, the clamping block 3 and the baffle 10 can clamp the aircraft fixing block 2 and the aircraft target calibration fixture body 1, and the clamping of the aircraft target calibration fixture body 1 and the aircraft fixing block 2 can lock the aircraft target calibration fixture body 1 and the aircraft fixing block 2.

[0025] A locking rod 5 is fixedly connected to the left side of the fixing plate 9. The aircraft target clamp body 1 and the aircraft fixing block 2 are respectively provided with reserved slots 4. A pressing block 3 is fixedly connected to the left side of the locking rod 5. The locking rod 5 is set inside the reserved slot 4. The locking rod 5 slides and rotates inside the reserved slot 4.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the clamping block 3 and locking rod 5 are inserted into the reserved slot 4. After insertion, the fixing plate 9 and baffle 10 are pushed to make the locking rod 5 slide inside the reserved slot 4. After the clamping block 3 slides out of the reserved slot 4, the baffle 10 is rotated to make the locking rod 5 drive the clamping block 3 to rotate. Rotating the clamping block 3 can prevent the clamping block 3 from re-entering the reserved slot 4 and affecting the locking of the aircraft target calibration fixture body 1.

[0027] Limiting blocks 6 are fixedly connected to the upper and lower ends of the left side of the baffle 10. Limiting slots 7 are opened at the upper and lower ends of the right side inside the main body 1 of the aircraft target calibration fixture. The limiting blocks 6 are embedded in the limiting slots 7.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, after rotating the clamping block 3, the baffle 10 is pushed so that the limiting block 6 on the left side of the baffle 10 is embedded in the limiting slot 7. Thus, the baffle 10 can be limited by the limiting block 6 and the limiting slot 7 to prevent the baffle 10 from sliding accidentally. Limiting the baffle 10 can also limit the locking rod 5 to prevent the clamping block 3 from being misaligned with the reserved slot 4 and affecting its use.

[0029] Working principle: In use, the clamping block 3 and locking rod 5 are inserted into the reserved slot 4. After insertion, the fixing plate 9 and baffle 10 are pushed to make the locking rod 5 slide inside the reserved slot 4. After the clamping block 3 slides out of the reserved slot 4, the baffle 10 is rotated to make the locking rod 5 drive the clamping block 3 to rotate. After the clamping block 3 is rotated, the baffle 10 is pushed so that the limiting block 6 on the left side of the baffle 10 is embedded in the limiting slot 7. Thus, the limiting block 6 and the limiting slot 7 can limit the baffle 10 to prevent it from sliding accidentally. Limiting the baffle 10 can also limit the locking rod 5 to prevent the clamping block 3 from being misaligned with the reserved slot 4 and affecting its use. Rotating the rotating block... 12. The rotating block 12 drives the bidirectional threaded rod 11 to rotate inside the threaded groove 13. Since the threaded groove 13 inside the threaded sleeve 8 and the bidirectional threaded rod 11 cooperate with each other, and the threads outside the bidirectional threaded rod 11 are opposite, the rotation of the bidirectional threaded rod 11 inside the threaded groove 13 can make the threaded sleeve 8 move against the fixing plate 9, so that the fixing plate 9 pulls the clamping block 3 closer to the aircraft fixing block 2 through the locking rod 5. Thus, the clamping block 3 and the baffle 10 can clamp the aircraft fixing block 2 and the aircraft target calibration fixture body 1, and the clamping of the aircraft target calibration fixture body 1 and the aircraft fixing block 2 can lock the aircraft target calibration fixture body 1 and the aircraft fixing block 2.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
