Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a burr grinding device for a 3D grid structure carbon fiber preform. Background Art

[0002] Carbon fiber is a new type of fiber material with high strength and high modulus with a carbon content of more than 95%. With the development of society, the application of carbon fiber in more and more industries is becoming more and more extensive, and the production of carbon fiber is becoming more and more mature. Among them, carbon fiber preforms are very popular. Existing carbon fiber preforms are prone to more burrs on the outside after production, so deburring and grinding equipment is needed.

[0003] According to the patent with publication number 202321719406.6, a burr grinding device for 3D grid structure carbon fiber preforms is disclosed, including a base, the outside of the base is fixedly connected to a drive motor, the outside of the drive motor is fixedly connected to a screw, the outside of the screw is threadedly connected to a support plate, the outside of the support plate is slidably connected to a connecting rod, the outside of the support plate is fixedly connected to two positioning plates, the inner side of the support plate is rotatably connected to a threaded rod, the outside of the threaded rod is threadedly connected to two slides, the outside of the slide is slidably connected to a support rod, the outside of the slide is fixedly connected to a rubber pad, the top of the base is fixedly connected to a support frame, two grinding motors are arranged on the outside of the support frame, and a grinding wheel is arranged on the outside of the grinding motor.

[0004] By adopting the above scheme, by turning the handle, the rotation of the handle drives the threaded rod to rotate, and the rotation of the threaded rod drives the two slides to move through the support rod, and the movement of the slides drives the rubber pad to move. When the two slides move to a certain position, the two carbon fiber preforms can be fixed with the cooperation of the two positioning plates, and then the grinding motor is started to drive the grinding wheel to rotate, and then the drive motor is started to drive the carbon fiber preform to move toward the grinding wheel, so that the carbon fiber preform can be polished. However, when polishing the carbon fiber preform, it is often necessary to grind the burrs on the four sides. When the other sides of the carbon fiber preform need to be polished, the carbon fiber preform needs to be clamped and fixed again, resulting in low efficiency when polishing the carbon fiber preform. To this end, we provide a burr grinding device for 3D grid structure carbon fiber preforms to solve the above problems. Utility Model Content
