Description
Technical Field
[0001] This invention relates to the field of panel clamping equipment, specifically a clamping device for preparing ultrathin carbon-carbon composite panels. Background Technology
[0002] Carbon / carbon composites are carbon matrix composites reinforced with carbon fibers and their fabrics. They have advantages such as low density (<2.0 g / cm3), high strength, high specific modulus, high thermal conductivity, low coefficient of expansion, good frictional properties, good thermal shock resistance, and high dimensional stability. They are considered to be one of the most promising high-temperature materials.

[0016] The present invention has the following advantages: The present invention provides an improved fixture for preparing ultrathin carbon-carbon composite panels, which, compared with similar equipment, has the following improvements:
[0017] The present invention discloses a fixture for preparing ultrathin carbon-carbon composite material panels. A clamping component is installed on the top side of the placement groove. An air pump and solenoid valve pressurize airflow into a second high-precision cylinder, which pushes a U-shaped groove block, causing a T-shaped disk and annular airbag to approach the side of the ultrathin carbon-carbon composite material. Simultaneously, the expansion of the annular airbag clamps and fixes the ultrathin carbon-carbon composite material around its perimeter. At this time, a linear guide assembly can be controlled to move a photoelectric thickness gauge left and right in front of the clamping platform, allowing it to collect data on the side thickness of the ultrathin carbon-carbon composite material. Then, a secondary controller controls a reversing valve to introduce air pressure into the first high-precision cylinder. This causes the first high-precision cylinder to move the rubber component and suction cup upwards, bringing them into contact with the bottom of the ultrathin carbon-carbon composite material. The suction cup is then pressed and adheres to the bottom of the ultrathin carbon-carbon composite material.
[0018] By setting control components on the top side of the clamping stage, airflow is forced into the third high-precision cylinder through an air pump and solenoid valve. This pressure change in the third high-precision cylinder drives the displacement plate and matrix camera to move back and forth on the second fixed frame. This displacement of the matrix camera allows for the acquisition of data on the regular length and surface parameters of the ultrathin carbon-carbon composite material. Then, the two-axis guide assembly drives the workpiece to move and adjust its position on the middle side of the second fixed frame, enabling the workpiece to process the surface of the ultrathin carbon-carbon composite material. Here, an infrared sensor emits light and senses the movement of the matrix camera. The matrix camera monitors the displacement distance of the displacement frame in the two-axis guide assembly, and a suction cup is used to adsorb the ultrathin carbon-carbon composite material, preventing vibration on its surface during processing due to the thinness of the material. This improves the clamping and processing effect of the ultrathin carbon-carbon composite material panel. Attached Figure Description

A flexible hose 376 for guiding flow is installed on the top pipe of the insertion pipe 375. The flexible hose 376 is inserted and fixed at the top slot of the quick connector 377.
[0036] The thickness monitoring component 38 includes a mounting bracket 381. The mounting bracket 381 is bolted to the front end of the clamping table 1. A linear guide rail assembly 382 for left and right adjustment is provided in the groove at the top of the mounting bracket 381. A photoelectric thickness gauge 383 for detecting the thickness of the panel is bolted to the top of the slider in the linear guide rail assembly 382. Clamping brackets 384 are welded and fixed to both sides of the front end face of the mounting bracket 381. The linear guide rail assembly 382 and the photoelectric thickness gauge 383 are both electrically connected to the programmable controller 4 to provide power to the linear guide rail assembly 382 and the photoelectric thickness gauge 383.
[0037] The inside of the fixed frame 31 and the top of the first air pressure box 33 are respectively provided with a limiting tube 321 and a through hole. The limiting tube 321 and the through hole are distributed along the same center line. The bottom of the reversing valve 322 is connected to the through hole pipe through a connecting pipe. The first air pressure box 33 provides airflow guidance for the reversing valve 322.
[0038] The front end of the second air pressure box 35 is provided with seven sets of solenoid valves 36 at equal intervals from left to right, and the first air pressure box 33, the second high-precision cylinder 372 and quick connector 377 and the third high-precision cylinder 54 are all installed in the pipeline of the solenoid valves 36 through connecting pipes.
[0039] The working principle of the fixture for preparing ultrathin carbon-carbon composite panels based on Example 1 is as follows:
[0040] When using this device, first place it in the work area, then connect it to an external power source to provide the power required for its operation.
[0041] When clamping the ultra-thin carbon-carbon composite material, the operator inserts the positioning component 39 into the positioning slot on the top of the clamping table 1, and inputs the pre-prepared program into the programmable controller 4. At the same time, the solenoid valve 36, the first air pressure box 33, and the second high-precision cylinder 372 are installed and connected through external pipes.
[0042] Then, the ultra-thin carbon-carbon composite material is placed on the top middle side of the clamping table 1. At this time, the air pump 34 is controlled by the programmable controller 4 to work, so that the air pump 34 pressurizes the airflow into the second air pressure box 35, and sends the airflow into the control component 5 through the solenoid valve 36, so that the control component 5 collects data on the regular length and surface parameters of the ultra-thin carbon-carbon composite material.
[0043] The programmable controller 4 can input the airflow to the second high-precision cylinder 372 according to the data, so that the second high-precision cylinder 372 pushes the U-shaped groove block 371 to slide inside the placement groove 2, and controls the airflow to be input into the annular airbag 374 through components such as quick connector 377 and hose 376. This causes the U-shaped groove block 371 to move and drive the T-shaped disk 373 and the annular airbag 374 to move closer to the side of the ultra-thin carbon composite material. At the same time, the annular airbag 374 expands to clamp and fix the ultra-thin carbon composite material around its perimeter.
[0044] At this time, the linear guide assembly 382 can be controlled to drive the photoelectric thickness gauge 383 to move in the left and right direction in front of the clamping table 1, so that it can collect data on the side thickness of the ultra-thin carbon-carbon composite material. Then, the data collected by the matrix camera 56 and the photoelectric thickness gauge 383 is used to control the secondary controller 326 in the area covered by the ultra-thin carbon-carbon composite material to work. In turn, the secondary controller 326 controls the reversing valve 322 inside the limit tube 321 to work. When the reversing valve 322 works, it introduces air pressure into the first high-precision cylinder 323, so that the first high-precision cylinder 323 drives the rubber part 324 and the suction cup 325 to move upward and contact the bottom of the ultra-thin carbon-carbon composite material. As a result, the suction cup 325 is adsorbed on the bottom of the ultra-thin carbon-carbon composite material due to compression.
[0045] Example 2:
[0046] Please see Figures 1-8 This invention discloses a fixture for preparing ultrathin carbon-carbon composite panels. Compared to Embodiment 1, this embodiment further includes: a control component 5, which includes a second fixing frame 51. The second fixing frame 51 is bolted to the top of the clamping platform 1, and a two-axis guide assembly 52 for adjustment is bolted to the bottom of the second fixing frame 51. The two-axis guide assembly 52 is specifically composed of a motor, a lead screw, and a displacement frame. An infrared sensor 53 for positioning is bolted to the displacement frame in the two-axis guide assembly 52, and a bolt for forward and backward displacement is bolted to the bottom rear side of the clamping platform 1. The third high-precision cylinder 54 is adjusted. A displacement plate 55 is bolted to the piston rod at the front end of the third high-precision cylinder 54. A matrix camera 56 for detection is bolted to the bottom of the displacement plate 55. The two-axis guide assembly 52, the infrared sensor 53, and the matrix camera 56 are all electrically connected to the programmable controller 4 to provide power to the two-axis guide assembly 52, the infrared sensor 53, and the matrix camera 56. A sensor for sensing and positioning with the infrared sensor 53 is bolted to the bottom right end of the displacement plate 55. The length of the matrix camera 56 is the same as the length of the fixing frame 31.
[0047] In this embodiment:
[0048] By setting the control solenoid valve 36, the airflow is forced into the third high-precision cylinder 54, thereby changing the pressure inside the third high-precision cylinder 54 and pushing the displacement plate 55 and the matrix camera 56 to move in the front and back direction on the second fixed frame 51, thereby causing the matrix camera 56 to move and collect data on the regular length and surface parameters of the ultrathin carbon-carbon composite material.
[0049] Then, the workpiece is moved by the two-axis guide assembly 52 to adjust its displacement in the second fixed frame 51, so that the workpiece can perform processing on the surface of the ultra-thin carbon-carbon composite material. Here, the infrared sensor 53 can emit light and perform sensing action with the matrix camera 56. The matrix camera 56 can monitor the displacement distance of the displacement frame in the two-axis guide assembly 52, and the suction cup 325 can adsorb the ultra-thin carbon-carbon composite material so that its surface will not vibrate due to the material thickness during the processing, thereby improving the clamping and processing effect of the ultra-thin carbon-carbon composite material panel.
[0050] This invention provides an improved fixture for preparing ultrathin carbon-carbon composite panels. A clamping component 3 is positioned on the top side of the placement groove 2. Airflow is forced into a second high-precision cylinder 372 via an air pump 34 and a solenoid valve 36. This cylinder pushes a U-shaped groove block 371, causing a T-shaped disk 373 and annular airbag 374 to approach the side of the ultrathin carbon-carbon composite material. Simultaneously, the annular airbag 374 expands to clamp and fix the ultrathin carbon-carbon composite material around its perimeter. At this time, the linear guide assembly 382 controls the photoelectric thickness gauge 383 to move laterally in front of the clamping platform 1, allowing it to collect data on the side thickness of the ultrathin carbon-carbon composite material. Then, a secondary controller 326 controls a reversing valve 322 to introduce air pressure into a first high-precision cylinder 323. This causes the first high-precision cylinder 323 to move the rubber component 324 and suction cup 325 upwards, bringing them into contact with the bottom of the ultrathin carbon-carbon composite material. The suction cup 325 is then pressed and adheres to the bottom of the ultrathin carbon-carbon composite material. A control unit 5 is installed on the top side of the clamping table 1. Airflow is forced into the third high-precision cylinder 54 through the air pump 34 and the solenoid valve 36, thereby changing the pressure inside the third high-precision cylinder 54 and pushing the displacement plate 55 and the matrix camera 56 to move in the front and back direction on the second fixed frame 51. This causes the matrix camera 56 to move and collect data on the regular length and surface parameters of the ultra-thin carbon-carbon composite material. Then, the two-axis guide assembly 52 drives the workpiece to move and adjust its position on the middle side of the second fixed frame 51, so that the workpiece can perform processing on the surface of the ultra-thin carbon-carbon composite material. Here, the infrared sensor 53 emits light and senses the movement with the matrix camera 56. The matrix camera 56 monitors the displacement distance of the displacement frame in the two-axis guide assembly 52, and the suction cup 325 adsorbs the ultra-thin carbon-carbon composite material to prevent vibration on its surface during processing due to the thinness of the material, thereby improving the clamping and processing effect of the ultra-thin carbon-carbon composite material panel.
