A cutting and clamping device

Abstract

A cutting and clamping device disclosed by the present invention includes a cutting table, a slider connecting frame, and a guiding block. The piston rod of the clamping oil cylinder is connected to the slider connecting frame. A balance block is hinged inside the slider connecting frame. The slider connecting frame is fixedly connected to a clamping sliding sleeve. Two guiding blocks arranged side by side are slidably arranged inside the clamping sliding sleeve, and the two guiding blocks are respectively arranged on both sides of the saw slot of the cutting table. The end of the guiding block is spherical and abuts against the balance block. When clamping a steel plate, if the surface of the steel plate is uneven, the guiding block will squeeze the balance block, and the balance block will rotate slightly, so that both the mother material side and the sub-material side of the steel plate on both sides of the saw blade are in contact with the guiding block, making the clamping more reliable, the forces on both sides of the saw blade are uniform, and the sawing effect is improved. The clamping slider and the cutting table are in sliding contact between planes within the entire clamping range, solving the problem of insufficient rigidity of the long-distance sliding of the slider when the clamping width changes greatly.

The slider connecting frame 2 is fixedly connected to a clamping sleeve 5. A sleeve guide plate 8 is fixedly connected to the outside of the clamping sleeve 5. The two sleeve guide plates 8 are arranged around the outside of the cutting table 1 and are in sliding fit with the cutting table 1. Two guide blocks 3 arranged side by side are slidably arranged inside the clamping sleeve 5, and the two guide blocks 3 are respectively arranged on both sides of the saw kerf 11 of the cutting table 1. The end of the guide block 3 is spherical and abuts against the balance weight 4. When the piston rod of the pressing oil cylinder expands and contracts, it drives the clamping sleeve 5 to slide on the cutting table 1. At the same time, the starting end of the guide block 3 presses or releases the steel plate 6. When the saw blade cuts the steel plate 6, the forces on the guide block 3 from the steel plates 6 on both sides of the saw blade are different, which will cause the balance weight 4 to rotate by a small angle, thereby ensuring that the forces on both sides of the saw blade are balanced and improving the sawing effect. In this embodiment, the sleeve guide plate 8 can guide the clamping sleeve 5.

[0020] According to a specific embodiment of the present invention, a cutting and clamping device provided by the present invention is composed of Figures 1 to 4 As shown in the figure, symmetric waist-shaped holes 51 are formed in the clamping sleeve 5.
