Mold threaded hole tapping device

Abstract

The invention relates to the technical field of mold manufacturing, and discloses a mold threaded hole tapping device. The mold threaded hole tapping device comprises a screw tap head, wherein a workbench is fixedly installed below the bottom end of the screw tap head, a fixing table located under the bottom end of the screw tap head is fixedly installed at the top end of the workbench, and a locking layer is fixedly installed on the inner side of the fixing table. According to the mold threaded hole tapping device, friction force between a workpiece and the inner surface of the locking layeris increased by utilizing soft protruding sphere bags on the surface of the locking layer, the torque is effectively counteracted, the pushing force of the screw tap head on the workpiece can be effectively reduced due to cavities in the protruding sphere bags and the soft characteristic of the protruding sphere bags, and the phenomena of dislocation and slippage of the workpiece are avoided; in addition, the top ends of the protruding sphere bags abut against the surface of the workpiece, so that the number of fixing points of workpiece is increased, and the stability of the workpiece is higher; and through a recycling basket, after tapping of the screw tap head is completed, remaining cuttings directly fall into the recycling basket along a circulating layer, and the situation that the cuttings are accumulated at the bottom end of the workpiece, and placement and fixation of the workpiece are influenced is avoided.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a slotting device for threaded holes of a mold. Background technique [0002] In the mold manufacturing process, it is necessary to slot the threaded hole on the mold, which is the tapping process, and the tapping process generally uses a CNC machine tool with an electric tap to tap the mold that has already drilled the threaded hole. The work of thread groove is widely used in the field of mold manufacturing because of the high precision of CNC manufacturing and the high quality of finished products. [0003] In the existing CNC tapping equipment, the mold workpieces are generally transported in a flowing water manner. An automatic transportation pipeline will put the workpieces onto the workbench in turn, and then push the workpieces to the bottom of the electric tap head by a mechanical pusher to offset the fixed parts on one side. , to fix the position of the work...
