The specific embodiment

See also Fig. 1 to shown in Figure 4, find out by knowing among the figure, described cutter holding device is to be arranged on the plummer 11 of pedestal 1 of processing machine, and described cutter holding device is to include gripper clamp 2, the cutter collar 3 and cutter 4, wherein:

Pedestal 1 upper side of described processing machine is to be provided with plummer 11, described plummer 11 has a plurality of perforation 111, and plummer 11 lower side are provided with a plurality of flexible members 12, and below plummer 11, and be provided with post rail 13 at a plurality of flexible member 12 2 ends, described post rail 13 is connected side with plummer 11 and is provided with sleeve 131.

A plurality of gripper clamps 2 are to be arranged at intervals at plummer 11 upper sides, described gripper clamp 2 includes two calipers 21, each caliper 21 has relative half U type opening 211 respectively, and the through hole 213 that runs through described caliper 21, and be formed with relative containing hole 212 with respect to the other end of half U type opening 211 at each caliper 21, be embedded with a compression spring 23 in the relative containing hole 212 of two calipers 21, and two calipers 21 are to be arranged in through hole 213 with perforation 111 and be fixedly arranged on the plummer 11 by fixture 24, make described gripper clamp 2 form a U type opening 22, the flange 221 of described gripper clamp 2U type opening 22 is V-shaped, and U type opening 22 outer ends of described gripper clamp 2 have the introduction part 25 of flaring, and by the compression spring 23 the elastic shrinkage ability flange 221 that is positioned at U type opening 22 edges is inwardly clamped, make 21 courts of two calipers be formed with the gap 26 of a flaring away from U type opening 22 sides.

See also shown in Figure 5, find out the cutter collar 3 by knowing among the figure, it has cutter hole 31, and externally is formed with annular groove 32, the annular groove 32 of the cutter collar 3 is the flange 221 with respect to gripper clamp 2U type opening 22, and described annular groove 32 is for being recessed V-arrangement shape.

See also Fig. 4 to shown in Figure 7, find out by knowing among the figure, the utility model is cutter 4 to be inserted in the cutter hole 31 of the cutter collar 3 when the group structure, and the cutter collar 3 inserted by the introduction part 25 that U type opening 22 outer ends of gripper clamp 2 are flaring, allow the U type opening 22 of gripper clamp 2 slightly expand by the elastic force of compression spring 23, make gap 26 driving fits of 21 flarings of two calipers, allow the annular groove 32 of the cutter collar 3 dock with the flange 221 at gripper clamp 2U type opening 22 edges, make the cutter collar 3 that is plugged with cutter 4 be positioned promptly to finish of the present utility model group of structure in the U type opening 22 of gripper clamp 2.

In sum, because gripper clamp 2 of the present utility model is to be coupling on the plummer 11 of the pedestal 1 of processing machine with fixture 24 by two calipers 21 that have relative half U type opening 211 respectively, and in the containing hole 212 of each caliper 21, be embedded with a compression spring 23 with respect to the other end formation of half U type opening 211, make described gripper clamp 2 form a U type opening 22, and the flange 221 of described U type opening 22 is V-shaped, and the cutter collar 3 docked with the U type opening 22 of gripper clamp 2 by the annular groove 32 that has with respect to gripper clamp 2U type opening 22 flanges 221, therefore when wearing and tearing take place in cutter 4 of the present utility model, only need the cutter collar 3 is extracted out by the U type opening 22 of gripper clamp 2, can apace cutter 4 be upgraded and pass through the introduction part 25 of gripper clamp 2U type opening 22 outer ends, the cutter collar 3 is inserted in the gripper clamp 2, and then improve in the prior art loaded down with trivial details step when changing cutter, and quicken operation procedure and increase operating efficiency.
