Description
Technical Field
The utility model relates to the technical field of dovetail rib processing, in particular to a dovetail rib threaded hole drilling and positioning die.
Background
The dove tail muscle is the component part of motor, because the assembly needs, need set up a plurality of screw hole along the full length on the dove tail muscle, and the screw hole processing is through drilling before and then tapping, and present dove tail muscle drilling mainly processes one by one through the rig, is difficult to guarantee the size precision.
Disclosure of Invention
The utility model aims to solve the problem that the conventional dovetail rib drilling is mainly processed one by one through a drilling machine, and the size precision is difficult to guarantee, and provides a dovetail rib threaded hole drilling positioning die.
The specific scheme of the utility model is as follows: a drilling and positioning die for a dovetail rib threaded hole comprises a lower die and an upper die, wherein the top surface of the lower die is provided with a plurality of parallel dovetail rib positioning grooves, the dovetail rib positioning grooves are arranged along the length direction of the lower die, the bottom surface of each dovetail rib positioning groove is provided with a plurality of positioning holes along the length direction, and four positioning shaft sleeves are arranged on the top surface of the lower die and away from the dovetail rib positioning grooves; the positioning shaft is arranged on the bottom surface of the upper die corresponding to each positioning shaft sleeve, an upper die positioning hole is arranged on the upper die corresponding to each positioning hole, a through hole is formed in the middle of the upper die, a threaded hole is formed in the top surface of the lower die corresponding to the through hole, a screw rod is arranged in the threaded hole, and the top end of the screw rod penetrates out of the through hole of the upper die upwards and is provided with a compression nut.
The cross section of the dove tail tendon positioning groove is in an inverted trapezoid shape.
The top surface of the lower die is also provided with a support column, the bottom surface of the support column avoids the dovetail rib positioning groove, and the top surface of the support column is in contact with the bottom surface of the upper die.
The working principle of the utility model is as follows: during actual drilling processing, a lower die is fixedly installed on a machine table of a drilling machine, a dovetail rib to be processed is placed in a dovetail rib positioning groove, an upper die is placed on the lower die, the upper die is aligned to a positioning shaft sleeve through a positioning shaft, the upper die is tightly pressed through a bolt after being positioned, and finally a drill bit of the drilling machine is moved to align to an upper die positioning hole to be processed one by one.
Compared with the prior art, the utility model has the following advantages: the drilling machine is positioned through the die, so that the drilling positioning is more accurate, the machining precision is improved, the positioning operation of operators is cancelled, the labor intensity is reduced, and the machining speed is increased.
