The movable clamping block 221 and the fixed clamping block are matched to clamp the woodworking chisel 60 in a matched mode, specifically, the woodworking chisel 60 is clamped in the direction shown in figure 1, namely, the chisel head of the woodworking chisel 60 is on the right side, the chisel handle is on the left side, the upper end of the fixed clamping block and the lower end of the movable clamping block 221 are both provided with a U-shaped clamping opening 23, the length direction of the bottom wall of the U-shaped clamping opening 23 is perpendicular to the length direction of the woodworking chisel 60, further, the fixed clamping block is provided with two convex blocks in the direction away from the rack 10, a distance is reserved between the two convex blocks, the convex blocks are provided with the U-shaped clamping openings 23, the U-shaped clamping openings 23 in the convex blocks are matched with the U-shaped clamping openings 23 in the movable clamping block 221 to clamp the woodworking chisel 60, the convex blocks.

Specifically, the movable clamping end 22 is slidably connected to the frame 10, a second telescopic cylinder 32 is fixed to the frame 10, a telescopic end of the second telescopic cylinder 32 is fixedly connected to the fixing block 222, and a telescopic direction of the telescopic end of the second telescopic cylinder 32 is parallel to a length direction of the frame 10. Furthermore, the rack 10 is provided with a slide rail 40 along the length direction of the rack 10, and the fixed block 222 is provided with a slide groove adapted to the slide rail 40, so that the movable clamping end 22 slides on the rack 10 more stably.

Furthermore, the lower end of the frame 10 is provided with a first telescopic cylinder 31, the telescopic end of the first telescopic cylinder tightly props the woodworking chisel, and the telescopic end of the first telescopic cylinder can apply force or component force perpendicular to the direction of the frame to the woodworking chisel. Specifically, the telescopic end of the first telescopic cylinder 31 is perpendicular to the length direction of the frame 10, and can push the carpenter's chisel 60 tightly. Namely, the U-shaped clamping opening 23 of the fixed clamping block, the U-shaped clamping opening 23 of the movable clamping block 221 and the telescopic end of the first telescopic cylinder 31 are matched, so that the woodworking chisel 60 is clamped in the vertical and longitudinal directions, and the clamping stability is ensured. Specifically, the first telescopic cylinder 31 and the second telescopic cylinder 32 may be air cylinders or hydraulic cylinders, and are correspondingly provided with matched air pump stations or hydraulic pump stations.

Specifically, the vertical frame 10 is rotatably connected to the manipulator through a rotating device 50, as shown in fig. 5 to 7, the rotating device 50 includes a connecting plate 51, a rotating shaft 52, a bearing seat 53, a bearing and a rotating shaft 52 holding plate, the back side of the connecting plate 51 is connected to the frame 10, the upper end and the lower end of the positive side of the connecting plate 51 are respectively provided with the bearing seat 53, the bearing seat 53 is internally provided with the bearing, the rotating shaft 52 is connected to the bearing in a key manner, the rotating shaft 52 holding plate includes a left holding plate 541 and a right holding plate 542 which are fixedly connected by bolts, the left holding plate 541 is fixedly connected to the manipulator, the right holding plate 542 is L-shaped, the longer side of the L-shaped right holding plate 542 is attached to the rotating shaft 52, the shorter side is attached to the connecting plate 51, the longer side of the L-shaped right holding plate 542 is left with a gap between the connecting plate 51, a second spring 55 is connected between the left holding plate 541 and the, the shorter side of the L-shaped right hugging plate 542 is adjacent to the second spring 55. After manipulator and frame rotate relatively, when the manipulator returned the normal position, the frame atress relatively, the second spring can make left enclasping board and frame realize reseing.

The utility model discloses a theory of operation does: the carpenter's chisel 60 is placed according to the direction shown in figure 1, wait for the clamping device to clamp to another station, when the clamping device clamps, the U-shaped clamping opening 23 of the fixed clamping block supports the lower side of the carpenter's chisel 60, drive the second telescopic cylinder 32 to extend, the movable clamping end 22 slides downwards on the slide rail 40 of the frame 10, because the four sides of the carpenter's chisel 60 are inclined, therefore, the movable clamping block 221 will swing slightly when supporting downwards to adapt to the inclined surface, when guaranteeing to clamp, the U-shaped clamping opening 23 of the fixed clamping block, the U-shaped clamping opening 23 of the movable clamping block 221 and the carpenter's chisel 60 are presented relatively parallel and level by the clamping surface. The first telescopic cylinder 31 is started, the telescopic end of the first telescopic cylinder 31 extends to abut against the back of the woodworking chisel 60, and the U-shaped clamping opening 23 of the clamping block is matched, so that the front of the woodworking chisel is also attached to the U-shaped clamping opening, and the forward and backward clamping of the woodworking chisel 60 is realized stably.
