Description

Technical Field

[0001] This utility model relates to the field of carbon fiber processing technology, and in particular to a positioning fixture for hydraulic processing of carbon fiber. Background Technology

[0002] Carbon fiber is a high-strength, high-modulus fiber with a carbon content of over 90%. Its microstructure is mainly composed of carbon atoms in the form of graphite microcrystals. It is made from organic fibers (such as polyacrylonitrile fiber, pitch fiber, etc.) through high-temperature carbonization, graphitization and other processes. It has many excellent properties and is widely used in aerospace, automotive, sporting goods and other fields. Some carbon fiber products usually need to be compressed and formed by hydraulic devices during processing. During compression, positioning fixtures are needed to position the molds to ensure stable compression processing of carbon fiber products.

[0003] Existing positioning fixtures can only clamp molds together for positioning. However, in actual use, when subjected to strong hydraulic pressure, the molds may shift between the molds and the clamping arms of the positioning fixture, making stable positioning impossible. Therefore, we propose a positioning fixture for carbon fiber hydraulic processing. Utility Model Content

[0014] In a further technical solution, the movable support limiting mechanism includes a first movable sleeve block located on the outer side of the surface of the first bidirectional threaded rod and a second movable sleeve block located on the outer side of the surface of the second bidirectional threaded rod.

[0017] In a further technical solution, the connecting clamping mechanism includes a connecting mounting plate. A fixed mounting end plate is fixedly connected to one top end of the connecting mounting plate, and a fixed positioning end block is fixedly connected to the other top end of the connecting mounting plate.

[0033] 5. Hydraulic mold body. Detailed Implementation

[0034] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0035] Example:

[0036] like Figures 1-6 As shown, a positioning fixture for carbon fiber hydraulic processing includes:

[0037] Mounting base plate 1, with symmetrical mounting feet on the lower part of its front and rear surfaces, is mounted on the operating table of the hydraulic processing device by bolts;

[0038] Adjustment mechanism 2 is fixedly welded to the top center of mounting base plate 1;

[0039] The movable support limiting mechanism 3 is fixedly installed at the output end of the adjusting mechanism 2;

[0040] The clamping mechanism 4 is fixedly mounted on the front and rear ends of the top of the adjusting mechanism 2;

[0041] The hydraulic mold body 5 is movably located on the top of the movable support limiting mechanism 3 and inside the connecting clamping mechanism 4, and its top is connected and fixed to the output end of the hydraulic device by bolts.

[0042] The working principle of the above technical solution is as follows:

[0043] During use, the adjustment mechanism 2 can be adjusted according to the size of the hydraulic mold body 5, so that the adjustment mechanism 2 can adjust the moving support limiting mechanism 3, so that the output end of the moving support limiting mechanism 3 can be aligned with the threaded mounting hole on the bottom of the hydraulic mold body 5. The hydraulic mold body 5 is placed on top of the moving support limiting mechanism 3, which restricts the hydraulic mold body 5 in the front-back and left-right directions. Then, the connecting clamping mechanism 4 is adjusted so that the connecting clamping mechanism 4 can clamp and fix the hydraulic mold body 5, while ensuring that the hydraulic mold body 5 can be used stably when driven by the hydraulic device, and is easy to operate.

[0044] In another embodiment, such as Figure 3 As shown, the adjustment mechanism 2 includes a fixed mounting frame 21. Fixed guide grooves 22 are provided on the upper part of both the front and rear surfaces of the fixed mounting frame 21. Fixed guide grooves 23 are symmetrically provided on the upper part of both the front and rear surfaces of the fixed mounting frame 21. A first bidirectional threaded rod 24 is symmetrically and movably arranged inside the fixed mounting frame 21. One end of the first bidirectional threaded rod 24 is fixedly connected to a first limiting end plate 25, and the other end of the first bidirectional threaded rod 24 is fixedly connected to a first servo motor 26. The first servo motor 26 is fixedly connected to one side of the fixed mounting frame 21. A movable mounting frame 27 is movably connected to the inner side of the fixed guide groove 23. A second bidirectional threaded rod 28 is movably connected inside the movable mounting frame 27. One end of the second bidirectional threaded rod 28 is fixedly connected to a second limiting end plate 29, and the other end of the second bidirectional threaded rod 28 is fixedly connected to a second servo motor 210. The second servo motor 210 is fixedly connected to the side of the movable mounting frame 27 away from the second limiting end plate 29.

[0045] When the first servo motor 26 drives the first bidirectional threaded rod 24, the first bidirectional threaded rod 24 can move the movable support limiting mechanism 3. The movable support limiting mechanism 3 can drive the second bidirectional threaded rod 28, the movable mounting bracket 27, the second limiting end plate 29, and the second servo motor 210 to move. Then, the second servo motor 210 can drive the second bidirectional threaded rod 28, so that the second bidirectional threaded rod 28 can adjust the movable support limiting mechanism 3. The structure is simple and the operation is convenient and quick.

[0046] In another embodiment, such as Figure 3 As shown, the outer side of the end surface of the movable mounting bracket 27 slides against the inner side of the fixed guide groove 23, and the outer side of the surface of the second bidirectional threaded rod 28 slides against the inner side of the fixed guide groove 22.

[0047] The end of the movable mounting bracket 27 can move stably inside the fixed guide groove 23, while the second bidirectional threaded rod 28 can move stably inside the fixed guide groove 22, making operation convenient and quick.

[0048] In another embodiment, such as Figure 4 As shown, the movable support limiting mechanism 3 includes a first movable sleeve block 31 located on the outer side of the surface of the first bidirectional threaded rod 24 and a second movable sleeve block 35 located on the outer side of the surface of the second bidirectional threaded rod 28. The end of the first movable sleeve block 31 is fixedly connected to a connecting support base block 32. The top of the connecting support base block 32 is symmetrically provided with a fixed guide block 33. The inner side of the fixed guide block 33 is movably connected to a movable support block 34. One side of the movable support block 34 is fixedly connected to one end of the second movable sleeve block 35. The inner side of the top of the movable support block 34 is connected to a limiting component 36 by a thread.

[0049] The first movable sleeve 31 can move on the outer side of the surface of the first bidirectional threaded rod 24, driving the connecting support base block 32, fixed guide block 33, movable support block 34, second movable sleeve 35, limiting component 36, second bidirectional threaded rod 28, movable mounting bracket 27, second limiting end plate 29 and second servo motor 210 to move. Then, the second movable sleeve 35 can move on the outer side of the surface of the second bidirectional threaded rod 28, driving the movable support block 34 and limiting component 36 to move, so that the bottom end of the movable support block 34 can move on the inner side of the fixed guide block 33, thereby adjusting the position of the limiting component 36, so that the bottom threaded mounting hole of the hydraulic mold body 5 can be directly fitted on the outer side of the limiting component 36 for connection.

[0050] In another embodiment, such as Figure 4 As shown, a connecting limiting sleeve 37 is fixedly connected to one side of the second movable sleeve 35.

[0051] When the end of the connecting limiting sleeve 37 is in contact with the inner side of the fixed mounting frame 21, the movable support block 34 is located at the inner end of the fixed guide block 33, which prevents the movable support block 34 from detaching from the inner side of the fixed guide block 33 and makes operation convenient.

[0052] In another embodiment, such as Figure 5 As shown, the limiting component 36 includes a threaded connecting rod 361 located inside the top of the movable support block 34. A fixed limiting rod 362 is fixedly connected to the top of the threaded connecting rod 361, and a rotating top block 363 is fixedly connected to the top of the fixed limiting rod 362.

[0053] This facilitates the rotation of the rotating top block 363, which in turn drives the fixed limit rod 362 and the threaded connecting rod 361 to rotate, allowing the threaded connecting rod 361 to disengage from the inner side of the top of the movable support block 34. The fixed limit rod 362 can be selected according to the threaded mounting hole size of the hydraulic mold body 5 itself, making operation convenient.

[0054] In another embodiment, such as Figure 6 As shown, the connecting clamping mechanism 4 includes a connecting mounting plate 41. A fixed mounting end plate 42 is fixedly connected to one top end of the connecting mounting plate 41, and a fixed positioning end block 43 is fixedly connected to the other top end of the connecting mounting plate 41. A third servo motor 44 is fixedly connected to the side of the fixed mounting end plate 42 away from the fixed positioning end block 43. A third bidirectional threaded rod 45 is fixedly connected to the output end of the third servo motor 44. The third bidirectional threaded rod 45 is located inside the fixed mounting end plate 42 and the fixed positioning end block 43. A third limiting end plate 46 is fixedly connected to the other end of the third bidirectional threaded rod 45. A movable clamping arm 47 is movably connected to the outer surface of the third bidirectional threaded rod 45 via threads.

[0055] The third servo motor 44 can drive the third bidirectional threaded rod 45 and the third limiting end plate 46, so that when the third bidirectional threaded rod 45 rotates, the moving clamping arm 47 can move, thereby clamping and fixing the hydraulic mold body 5, so that the hydraulic mold body 5 can be used stably and the operation is convenient and quick.

[0056] The working principle of this utility model is as follows: During use, the rotating top block 363 rotates, causing the fixed limiting rod 362 and the threaded connecting rod 361 to rotate, so that the threaded connecting rod 361 disengages from the inner side of the top of the moving support block 34. The fixed limiting rod 362 is selected according to the threaded mounting hole size of the hydraulic mold body 5. After selection, the threaded connecting rod 361, the fixed limiting rod 362, and the rotating top block 363 are installed. Then, the first servo motor 26 can move the first bidirectional threaded rod 24 and the first limiting end plate 25. The drive causes the first bidirectional threaded rod 24 and the first limiting end plate 25 to rotate, thereby causing the first moving sleeve block 31, the connecting support base block 32, the fixed guide side block 33, the moving support block 34, the second moving sleeve block 35, the limiting assembly 36, the connecting limiting sleeve 37, the second bidirectional threaded rod 28, the moving mounting bracket 27, the second limiting end plate 29, and the second servo motor 210 to move. This allows the end of the moving mounting bracket 27 to move inside the fixed guide groove 23, while the second bidirectional threaded rod 28 can stably move within the fixed guide groove 23. The second servo motor 210 then drives the second bidirectional threaded rod 28 and the second limiting end plate 29, causing the second moving sleeve 35 to move on the outer surface of the second bidirectional threaded rod 28 as it rotates. This causes the connecting limiting sleeve 37, the moving support block 34, and the limiting assembly 36 to move as a whole. The hydraulic mold body 5 is then moved so that the threaded mounting hole at the bottom of the hydraulic mold body 5 fits onto the outer surface of the fixed limiting rod 362, allowing the moving support block 34 and the connecting support base block 32 to lift the hydraulic mold body 5 and simultaneously restrict its movement in the front-back, left-right, and right directions. Finally, the third servo motor 44 drives the third bidirectional threaded rod 45 and the third limiting end plate 46, causing the moving clamping arm 47 to move on the outer surface of the third bidirectional threaded rod 45 as it rotates, clamping and fixing the hydraulic mold body 5. This ensures stable use of the hydraulic mold body 5. The overall structure is simple and the operation is convenient and quick.

[0057] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
