Detailed Description
The technical scheme of the utility model is explained in detail below with the attached drawings:
like fig. 1 and 2, a carbon fiber preform member terminal surface cutting device, including controlling two sets of supports 1, still include steel axis of rotation 2, the both ends of axis of rotation 2 and two sets of supports 1 one-to-one just are connected through the rotation mode respectively, realize the gyration of axis of rotation 2 for support 1.
The connection between the rotating shaft 2 and the support 1 can be realized by a common ball bearing or a sliding bearing, but preferably by a spherical bearing, and the end of the rotating shaft 2 is matched with the inner hole of the bearing.
Two groups of mounting through holes are arranged on the support 1 and are respectively positioned on two sides of the spherical bearing. Used for realizing the connection with the fixed frame.
By adopting the spherical bearing, the support 1 can rotate relative to the rotating shaft 2 at multiple angles, so that the position and the angle of the support 1 can be adjusted at will when the support is installed, and the support cannot be easily influenced by the flatness of a rack and the structure of the rack.
The cutting device further comprises a wrench 4 and a cutter handle 3 which are respectively perpendicular to the rotating shaft 2, a threaded hole is formed in the front end of the cutter handle 3, a cutter clamping plate is mounted through the threaded hole, and a cutting blade is fixed at the front end of the cutter handle 3. Connecting holes are formed in the front end of the wrench 4 and the rear end of the handle 3 respectively and matched with the rotating shaft 2, and a linear guide mechanism is arranged on the rotating shaft 2 and used for restraining that the wrench 4 and the handle 3 can only move along the axial direction of the rotating shaft 2 and cannot rotate relative to the rotating shaft 2.
