Double-end tapping device for sphygmomanometer watchcase

Abstract

The invention provides a double-end tapping device for a sphygmomanometer watchcase, and solves the problems that when an internal thread of the sphygmomanometer watchcase is machined by adopting a conventional machining method, not only is the machining efficiency low, but also the machining precision is easily influenced by repeated workpiece clamping and the labor intensity of workers is very high. The double-end tapping device comprises a baseplate, a double-end automatic tapping machine and a PLC control system, wherein a vertically-arranged workpiece limiting groove is arranged at the front end of a bracket; a first air cylinder and a first electromagnetic valve are mounted on the rear side of the bracket; a supporting plate is fixedly connected with the front end of a piston rod of the first air cylinder; a second air cylinder and a second electromagnetic valve are mounted on the front side of the bracket; an inductive switch, directly facing a workpiece positioned at the bottom of the workpiece limiting groove, is mounted on the bracket; two screw taps of the double-end automatic tapping machine are aligned with the to-be-machined position of the workpiece positioned at the bottom of the workpiece limiting groove; a first contact rod and a second contact rod are mounted on a main shaft of the double-end automatic tapping machine; and a first travel switch and a second travel switch are mounted in the double-end automatic tapping machine.

Description

technical field [0001] The invention relates to the technical field of tapping tooling, in particular to a double-head tapping device for a sphygmomanometer watch case. Background technique [0002] figure 1 and figure 2 A sphygmomanometer watch case 1 is provided with two oppositely arranged bosses 3 on the outside of the rear side wall of the sphygmomanometer watch case. In order to fix the movement, it is necessary to process two internal threads 2 on the inner side of the rear side wall of the sphygmomanometer case 1 by using a double-head tapping machine. The current processing method usually needs to be done manually. First, a tapping machine is used to process the inner thread of a sphygmomanometer case, and then the sphygmomanometer case is removed and re-clamped to process another sphygmomanometer case. The processing method not only has low processing efficiency, but also the repeated clamping of the workpiece can easily affect the processing accuracy, and the ...
