Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the utility model relates to a hexagonal screw end mills structural schematic diagram of circle frock.
Detailed Description
The following examples are presented to enable those skilled in the art to more fully understand the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, a schematic structural diagram of a hexagon screw end milling tool comprises a milling device 1 and a feeding positioning device 2, the milling device 1 comprises a clamping rotating mechanism and a milling cutter 16, the clamping rotating mechanism comprises a first clamping block 13, a second clamping block 14, a slide rail 12 and a motor 11, the first clamping block 13, the second clamping block 14 and the slide rail 12 are wrapped in a shell 17, the motor 11 is positioned on the left side of the shell 17, the first clamping block 13 and the second clamping block 14 are positioned on the right side of the slide rail 12, the left side of the slide rail 12 is connected with the motor 11, a clamping opening is formed between the first clamping block 13 and the second clamping block 14, a recess is formed on the surfaces of the first clamping block 13 and the second clamping block 14 in the clamping opening, an opening is formed in the middle of the right side surface of the shell 17, the opening is opposite to the clamping opening and can be inserted into a screw rod of a hexagon nut 3, the milling cutter 16 is positioned below the opening on the outer side of the shell 17, the, the bottom of the milling cutter 16 is connected with a slide block 15, and the slide block 15 slides outside a shell 17. The feeding positioning device 2 comprises an inner hexagonal sleeve 21 and an L-shaped positioning insertion piece 22, the inner hexagonal corresponds to the outer hexagonal of the head of the hexagonal screw, the sleeve 21 is sleeved on the head of the hexagonal screw 3, the L-shaped positioning insertion piece 22 is fixed on the outer bottom surface of the feeding positioning device 2, one edge of the positioning insertion piece 22 is attached to the outer bottom surface of the round sleeve 21, and the other edge of the positioning insertion piece faces to the opening direction of the round sleeve 21 and does not attach to the outer side surface of the feeding positioning device and further exceeds the outer side surface by one section.
