In the process of clamping the cutter by the cutter holder 10 for the PCB drilling machine, one end of the cutter is inserted into the grabbing groove 301 formed in the grabbing part 320 by an external drilling machine, and since the grabbing part 320 is provided with a plurality of grabbing gaps 302 around the grabbing groove 301, when the cutter is inserted into the grabbing groove 301, the grabbing part 320 is elastically deformed to tightly clamp and fix one end of the cutter. When the gripper 300 is damaged, the cover plate 200 can be detached from the tool holder body 100, and then the damaged gripper can be replaced, so that the cost is low and the efficiency is high.

The tool holder body 100 is used for receiving the cover plate 200, the gripper 300 and the elastic member 400. Specifically, the placing groove 101 formed in the tool holder body 100 is used for placing the receiving cover plate 200. The cover plate 200 is inserted into the placement groove 101 and detachably connected to the holder body 100. Further, in the present embodiment, the holder body 100 is a cylindrical structure, and the cover plate 200 is inserted into the placing groove 101 and is screwed with the holder body 100. In another embodiment, the cover plate is inserted into the placing groove and clamped with the tool apron body. When the gripper 300 is damaged, the cover plate 200 may be detached from the tool holder body 100, and then the damaged gripper may be replaced. The tool holder body 100 has an accommodating cavity 102 for accommodating the gripper 300 and the elastic member 400. The accommodating groove 102 is communicated with the placing groove 101, and the gripper 300 passes through the accommodating groove 102 and the placing groove 101 and is exposed out of the tool apron body 100.

The receiving cover 200 is used to cooperate with the tool holder body 100 to fix the gripper 300 and the elastic member 400 on the tool holder body 100. In the present embodiment, the receiving cover 200 has a circular plate structure. The cross section of the placing groove 101 formed in the tool apron body 100 is circular. The cover plate 200 is inserted into the placement groove 101 and detachably connected to the holder body 100. The gripper 300 is exposed out of the cover plate 200 through the through opening 201 formed in the receiving cover plate 200. In the present embodiment, the portion of the gripper 300 passing through the through hole 201 formed in the receiving cover plate 200 and exposed out of the cover plate 200 is a cylindrical tubular structure, and correspondingly, the cross section of the through hole 201 is circular.

The gripper 300 is used to grip a tool for machining, and the coupling portion 310 in the gripper 300 is used to fix the position of the gripper 300. Specifically, the size of the through hole 201 formed in the receiving cover plate 200 is the same as that of the grabbing portion 320 in the gripper 300, and since the width of the connecting portion 310 is larger than that of the grabbing portion 320, when the grabbing portion 320 in the gripper 300 passes through the through hole 201 and is exposed out of the cover plate 200, the connecting portion 310 in the gripper 300 is clamped at the through hole 201 formed in the cover plate 200, so as to fix the gripper 300. The grabbing part 320 in the gripper 300 is used for grabbing a tool to be used, and when the tool is inserted into the grabbing groove 301, since the grabbing part 320 is provided with a plurality of grabbing gaps 302 around the grabbing groove 301, the grabbing part 320 is elastically deformed to tightly clamp and fix one end of the tool. Further, the grasping portion 320 is evenly opened with a plurality of grasping gaps 302 around the grasping groove 301, so that each portion of the grasping portion 320 is evenly stressed when the cutter is inserted into the grasping groove 301, thereby improving the service life of the grasping portion 320. Further, four grabbing gaps 302 are formed in the grabbing portion 320 around the grabbing groove 301, so that each portion of the grabbing portion 320 is uniformly stressed, and each portion of the grabbing portion 320 has high structural strength.

The elastic member 400 is used to prevent the gripper 300 from being in hard contact with the tool holder body 100. When an external drill grips a tool on the gripper 300 or places the tool on the gripper 300, a certain downward pressure is applied to the gripper 300. The elastic member 400 prevents the gripper 300 from being directly and rigidly contacted with the tool holder body 100, and prevents the gripper 300 from being worn by the tool holder body 100. In this embodiment, the elastic member 400 is elastic plastic. In one embodiment, the resilient member is a spring. Further, the elastic member is a compression spring. In other embodiments, the elastic member is an elastic rubber. The rubber has good wear resistance and corrosion resistance, is tough compared with plastic and soft compared with metal, and prolongs the service life of the elastic part.

In order to improve the working stability of the tool holder for the PCB drilling machine, referring to fig. 3, in one embodiment, in the gripper 300, the connecting portion 310 is provided with a connecting groove 303 away from the grabbing portion 320, the connecting groove 303 is communicated with the accommodating groove 102, the elastic element 400 is adapted to the connecting groove 303 provided in the connecting portion 310, and the elastic element 400 is accommodated in the connecting groove 303 and movably abutted against the connecting portion 310. Thus, the connection stability of the elastic member 400 and the gripper 300 is further increased, and the working stability of the tool holder for the PCB drilling machine is improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
