  • Patent number: 11890714
    Abstract: A remanufacturing method of a drill includes providing a drill with a worn-out area. The drill comprises: a shank part; and a flute part arranged on one end of the shank part. A chisel edge is formed on the front end of the flute part, and the radius of any one of the cross section of the chisel edge is defined as a core thickness; a first blade and a second blade with tilt directions toward the shank part are formed on the two sides of the chisel edge. The first circumferential surface of the first blade and the second circumferential surface of the second blade are respectively extended and spiraled toward the shank part along a periphery of the flute part and form two helical cutting edges, a first debris-discharging groove and a second debris-discharging groove. The first blade comprises a first cutting edge. The first cutting edge and the first circumferential surface define the worn-out area.

  • Patent number: 11305436
    Abstract: A lateral gripper includes a gripper mount, and two gripper jaw modules assembled on the gripper mount. Each gripper jaw module includes a sliding block and a gripper jaw. The sliding block drives the gripper jaw to slide on the gripper mount. The gripper jaw is configured to grip a drill box by multi-point contact, so that the freedom of the drill box is restricted, and the drill box can be stably carried by the gripper jaw modules.

  • Patent number: 10976153
    Abstract: A forming tool detection device includes a reflector module, an image sensor and a backlight module respectively disposed on both sides of the reflector module with a detection space formed between the backlight module and the reflector module for the insertion of a forming tool for detection. The reflector module focuses the light projected by the backlight module and reflects the focused light toward the backlight module and is provided with a hollow portion for the image sensor to capture an image of the forming tool. The reflector module is used to reflect the light emitted by the backlight module so that the tool image captured by the image sensor can detect the length and outer diameter of the forming tool, thereby simplifying the tool detection process.

  • Patent number: 10906753
    Abstract: A cyclic type layered storage and output equipment includes a first pick-and-place device and a second pick-and-place device set at two opposite sides of an automatic material distribution and storage machine for delivering drill bits for detection and storing the detected drill bits by using horizontal transportation and layered storage technology. It can reduce the equipment space. After the overall inspection is completed, all the stored drill bits are transferred to another processing equipment together.
