Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber production, in particular to a polishing and grinding device for carbon fiber production. Background Art

[0002] Carbon fiber is an inorganic high-performance fiber with a carbon content of more than 90% that is converted from organic fiber through a series of heat treatments. It is a new material with excellent mechanical properties. It has the inherent characteristics of carbon materials and the softness and processability of textile fibers. Therefore, carbon fiber products have high strength and hardness, far exceeding metal materials of the same volume and weight. Therefore, carbon fiber products are widely used in high-tech industrial fields such as aviation, navigation, and military industry. There are many types of carbon fiber products, and the performance of products produced by different processes is also different. Before painting the carbon fiber products, their outer walls need to be polished to enhance the adhesion of the paint, so that the products have good performance.

[0003] A search revealed a fiber tube edge and corner grinding mechanism with patent publication number CN221455351 U, which states that "by providing a first box body and a door, a large amount of debris generated during fiber tube edge grinding is directed into a collection tank through a collection cover for collection, thereby preventing the fiber tube grinding debris from flying and splashing, further improving the safety of the device."

[0004] However, the above solution still has certain deficiencies in actual use. The solution uses a fixing mechanism to assist in clamping the periphery of the carbon fiber tube. However, the carbon fiber tube cannot be adjusted in angle after being clamped by the fixing mechanism. When processing different positions of the carbon fiber tube is required, the carbon fiber tube needs to be disassembled in advance and then adjusted in angle before assembly, which greatly reduces the processing efficiency of the carbon fiber tube.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model discloses a polishing and grinding equipment for carbon fiber production, including a processing table 1, the top of which is provided with a rolling seat 3, a follower structure 4, a rotary clamping device 5 and a grinding device 6, the follower structure 4 is located on the right side of the rolling seat 3, the rotary clamping device 5 is located on the left side of the rolling seat 3, and the grinding device 6 is located behind the rolling seat 3.

[0024] The follower structure 4 includes a servo electric cylinder 401 , which is fixedly mounted on the top of the processing table 1 via a placement seat, and an arc-shaped clamping plate 402 is fixedly mounted on the movable end of the servo electric cylinder 401 .

[0025] The rotary clamping device 5 includes a back plate 501, the back side of which is rotatably connected to a gear handle 502, and the other end of the gear handle 502 is fixedly installed with a rotating box 503, which is located on the inner side of the back plate 501, and the inner wall of the rotating box 503 is slidably connected to a resistance arc plate 506 through an electric push rod 505.

[0026] By setting up a rotary clamping device 5, the electric push rod 505 on the inner side of the rotating box 503 can be used to prompt the contact arc plate 506 to adaptively clamp the inner wall of the carbon fiber tube, and then cooperate with the gear turn handle 502 to drive the rotating box 503 to rotate, so that the angle of the carbon fiber tube on one side of the rotating box 503 can be adjusted, so that the clamping device can flip the carbon fiber tube in the clamping state, thereby avoiding the need to disassemble the carbon fiber tube in advance and then adjust its angle before assembling it, thereby significantly improving the production efficiency of the carbon fiber tube.

[0027] The grinding device 6 includes an electric slide rail 601, a movable frame 602 is fixedly installed on the movable end of the electric slide rail 601, a linear motor 603 is provided on the inner side of the movable frame 602, a hydraulic cylinder 604 is provided on the movable end of the linear motor 603, and a grinding wheel 605 is provided on the movable end of the hydraulic cylinder 604.

[0028] Specifically, a protective cover shell 2 is slidably connected to the rear of the processing table 1, and an observation window is slidably connected to the opening of the protective cover shell 2.

[0029] In this embodiment, the protective cover shell 2 can cover the carbon fiber tube when the grinding device is working, thereby preventing waste chips generated during the grinding process from flying around.

[0030] Specifically, the inner side of the arc-shaped clamping plate 402 is rotatably connected to rollers, and the number of the rollers is not less than five.

[0031] In this embodiment, the rollers on the inner side of the arc-shaped clamping plate 402 are overlapped with the outer side of the carbon fiber tube, so that a sliding connection is formed between the carbon fiber tube and the arc-shaped clamping plate 402 .

[0032] Specifically, the front cover 504 is movably engaged with the opening of the rotating box 503 . A vertical slot is defined inside the front cover 504 , and the abutting arc plate 506 extends to the outside of the rotating box 503 through the vertical slot.

[0033] In this embodiment, the vertical groove inside the front cover 504 can be used to guide the movement trajectory of the arc plate 506.

[0034] Specifically, the back side of the back plate 501 is rotatably connected to a limiting rack 507 , and the back side of the back plate 501 is slidably connected to a positioning frame 509 via a guide rail 508 .

[0035] In this embodiment, when the angle of the clamped carbon fiber tube needs to be adjusted, the gear handle 502 is rotated so that the gear handle 502 drives the clamped carbon fiber tube to adjust its angle through the rotating box 503;

[0036] When locking is required after the angle is adjusted, the limit rack 507 is rotated to cause the limit rack 507 to gradually approach a horizontal placement state, causing the bottom end of the limit rack 507 to engage with the gear turn handle 502 at this time, and then the positioning frame 509 is pulled to cause the positioning frame 509 to frame the side end of the limit rack 507 into its inner side, so that the limit rack 507 can no longer rotate, and then the gear turn handle 502 can no longer rotate, thereby completing the locking operation after the angle adjustment.

[0037] During use, the carbon fiber tube is first placed on the rolling seat 3, so that the two abutting arc plates 506 penetrate into the inner side of one end of the carbon fiber tube, and the other end of the carbon fiber tube is located between the two arc-shaped clamping plates 402. Then, the follower structure 4 is started, so that the movable end of the servo electric cylinder 401 drives the arc-shaped clamping plate 402 to gradually overlap with the side end of the carbon fiber tube, so that the roller inside the arc-shaped clamping plate 402 overlaps with the outer side of the carbon fiber tube, so that a sliding connection is formed between the carbon fiber tube and the arc-shaped clamping plate 402.

[0038] Then, the rotary clamping device 5 is started, and the movable end of the electric push rod 505 drives the contact arc plate 506 to move, so that the outer side of the contact arc plate 506 gradually overlaps the inner wall of the carbon fiber tube, so that the contact arc plate 506 and the carbon fiber tube are in a close-fitting clamping state.

[0039] When the angle of the clamped carbon fiber tube needs to be adjusted, the gear handle 502 is rotated so that the gear handle 502 drives the clamped carbon fiber tube to adjust its angle through the rotating box 503;

[0040] When locking is required after the angle adjustment, the limiting rack 507 is rotated to gradually approach a horizontal position, causing the bottom end of the limiting rack 507 to mesh with the gear handle 502. Then, the positioning frame 509 is pulled to cause the positioning frame 509 to frame the side end of the limiting rack 507 inside itself, so that the limiting rack 507 cannot rotate anymore, thereby causing the gear handle 502 to be unable to rotate, thereby completing the locking operation after the angle adjustment.

[0041] When the carbon fiber tube needs to be polished, the mobile frame 602 is moved to the specified position by the electric slide rail 601, and then the grinding wheel 605 is moved to the specified position by the linear motor 603. Then the hydraulic cylinder 604 is started to drive the grinding wheel 605 down to the point to be polished, and finally the grinding wheel 605 is started to start the grinding and polishing process.

[0042] To sum up, the polishing and grinding equipment for carbon fiber production is equipped with a rotary clamping device 5. The electric push rod 505 on the inside of the rotating box 503 can prompt the resistance arc plate 506 to adaptively clamp the inner wall of the carbon fiber tube. The gear handle 502 can drive the rotating box 503 to rotate, so that the angle of the carbon fiber tube on one side of the rotating box 503 can be adjusted, and the clamping device can flip the carbon fiber tube in the clamping state, thereby avoiding the need to disassemble the carbon fiber tube in advance and then adjust its angle before assembling it, thereby significantly improving the production efficiency of the carbon fiber tube.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
