Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a carbon fiber tube grinding device. Background Technology

[0002] Carbon fiber tubes, also known as carbon fiber tubes, are made by pre-impregnating carbon fiber composite materials with styrene-based polyester resin, winding them, heating and curing them through pultrusion. After molding, they need to be ground and polished to facilitate subsequent processing.

[0003] Currently, most carbon fiber tube production workshops use belt sanders or grinding wheels to grind the tubes. The carbon fiber tubes are sent to the grinding position by conveyor rollers or conveyor belts. However, there are some functional deficiencies in actual use, which have room for improvement. For example, during the grinding process, the hollow carbon fiber tubes are easily squeezed and may vibrate slightly, affecting the uniformity and consistency of the grinding. They also lack the function of internal support to prevent deformation and jumping.

[0004] Now, a novel carbon fiber tube grinding device is proposed to solve the above problems. Utility Model Content

[0007] The limiting component includes a first fixed seat, which is fixedly connected to the right side of the top of the bottom support frame. A first electric cylinder is installed on the right side of the first fixed seat, and a first clamping plate is movably connected to the output end of the first electric cylinder. A second fixed seat is fixedly connected to the left side of the top of the bottom support frame, and a reduction motor is installed on the left side of the second fixed seat. A second clamping plate is fixedly connected to the output end of the reduction motor. Multiple sets of annular grooves are respectively opened on the opposite surfaces of the first clamping plate and the second clamping plate. An inner liner tube is transversely arranged between the first clamping plate and the second clamping plate, and internal threaded positioning sleeves are respectively sleeved on both sides of the outer side of the inner liner tube.

[0008] As a further technical solution of this utility model, the first clamping plate and the second clamping plate have the same shape and size, and the horizontal center lines of the first clamping plate, the second clamping plate, and the inner liner tube coincide.

[0009] As a further technical solution of this utility model, the inner and outer diameters of the inner lining tube are adapted to the inner and outer diameters of one of the annular grooves, and the inner lining tube extends into the interior of one of the annular grooves.

[0010] As a further technical solution of this utility model, the two sides of the outer side of the inner liner tube are respectively threaded, the threads on the outer side of the inner liner tube and the threads inside the inner thread positioning sleeve are matched, and the control box, the first electric cylinder and the reduction motor are electrically connected.

[0011] As a further technical solution of this utility model, the first lead screw slider can slide back and forth along the interior of the first single-axis servo drive unit, and the second lead screw slider can slide left and right along the interior of the second single-axis servo drive unit.

A first electric cylinder 4 is installed on the right side of the first fixed seat 3. The output end of the first electric cylinder 4 is movably connected to a first clamping plate 5. A second fixed seat 6 is fixedly connected to the left side of the top of the bottom support frame 1. A reduction motor 7 is installed on the left side of the second fixed seat 6. The output end of the reduction motor 7 is fixedly connected to a second clamping plate 8. Multiple sets of annular grooves 21 are respectively opened on the opposite surfaces of the first clamping plate 5 and the second clamping plate 8. An inner liner tube 9 is arranged transversely between the first clamping plate 5 and the second clamping plate 8. Internal threaded positioning sleeves 10 are respectively sleeved on both sides of the outer side of the inner liner tube 9.

[0026] The first clamping plate 5 and the second clamping plate 8 have the same shape and size. The horizontal center lines of the first clamping plate 5, the second clamping plate 8, and the inner liner tube 9 coincide. The inner and outer diameters of the inner liner tube 9 are matched with the inner and outer diameters of one set of annular grooves 21. The inner liner tube 9 extends into the interior of one set of annular grooves 21 to facilitate support of the pipe and prevent deformation or vibration during the grinding process.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the inner liner tube 9 is inserted along the opening of the carbon fiber tube, with both sides of the inner liner tube 9 aligned with the annular grooves 21 on the first clamping plate 5 and the second clamping plate 8. The first electric cylinder 4 pushes the first clamping plate 5 to the left, and the first clamping plate 5 and the second clamping plate 8 clamp the inner liner tube 9 tightly, while simultaneously pressing against the end of the carbon fiber tube. During the grinding process, the reduction motor 7 drives the second clamping plate 8 to rotate at a constant speed, cooperating with the grinding head 20 to perform grinding. The inner liner tube 9 supports the interior of the carbon fiber tube, preventing it from deforming and jumping.

[0028] The inner liner tube 9 has threads on both sides of its exterior. The threads on the exterior of the inner liner tube 9 match the threads inside the inner thread positioning sleeve 10.

[0030] The first lead screw slider 13 can slide back and forth along the inside of the first single-axis servo drive unit 12, the second lead screw slider 16 can slide left and right along the inside of the second single-axis servo drive unit 15, the output end of the second electric cylinder 17 is fixedly connected to the top of the motor mounting plate 18, and the control box 2, the first single-axis servo drive unit 12, the second single-axis servo drive unit 15, the second electric cylinder 17, and the drive motor 19 are electrically connected, which can adapt to carbon fiber tubes with tapered or irregular shapes.

[0031] Specifically, such as Figure 1 and Figure 5 As shown, the drive motor 19 drives the grinding head 20 to rotate at high speed. The first single-axis servo drive unit 12, together with the first lead screw slider 13, can drive the horizontal support 14 to move back and forth.

With the help of the second electric cylinder 17, the height can be adjusted to adapt to irregularly shaped and tapered pipes.

[0032] Working Principle: In use, the cured carbon fiber tube is first placed on the bottom support 1. A set of inner lining tubes 9 with the same inner diameter as the carbon fiber tube is taken and inserted along the opening of the carbon fiber tube. The two sides of the inner lining tube 9 are aligned with the annular grooves 21 on the first clamping plate 5 and the second clamping plate 8. The first electric cylinder 4 pushes the first clamping plate 5 to the left, and the first clamping plate 5 and the second clamping plate 8 clamp the inner lining tube 9 tightly, while simultaneously pressing against the end of the carbon fiber tube. During the grinding process, the reduction motor 7 drives the second clamping plate 8 to rotate at a constant speed, cooperating with the grinding head 20 for grinding. The inner lining tube 9 supports the interior of the carbon fiber tube, preventing it from deforming and jumping. If the length of the carbon fiber tube and the length of the inner lining tube 9 differ significantly, the first clamping plate 5 and the second clamping plate 8 cannot press against the end of the tube tightly. Before clamping, the inner threaded positioning sleeves 10 are first put on both ends of the inner lining tube 9 and tightened. The two sets of inner threaded positioning sleeves 10 clamp the two ends of the carbon fiber tube and lock it in place. As the carbon fiber tube is fixed, the drive motor 19 drives the grinding head 20 to rotate at high speed. The first single-axis servo drive unit 12, together with the first lead screw slider 13, can drive the transverse support 14 to move back and forth. The second single-axis servo drive unit 15 drives the motor mounting plate 18 to move left and right through the second lead screw slider 16, so the position of the grinding head 20 can be changed. With the help of the second electric cylinder 17 to adjust the height, it can adapt to irregularly shaped and tapered tubes.
