Abstract
The invention discloses a manufacturing assembly for a thread in a hole. The manufacturing assembly comprises a support, a motor, a transmission mechanism, a clamp and a cutter, wherein the motor, the transmission mechanism, the clamp and the cutter are arranged on the support. The transmission mechanism comprises a shaft box and a transmission shaft arranged in the shaft box. The motor drives the cutter to do the rotation motion through the transmission shaft. Wheels are arranged at the bottom of the support. The transmission shaft comprises a driving shaft used for being connected with the motor and a driven shaft used for being connected with the cutter. The driving shaft and the driven shaft are connected through a skidding mechanism. The skidding mechanism comprises an auxiliary end face tooth fixedly connected with the driven shaft, a main end face tooth which is movably connected with the driving shaft and can axially move along the driving shaft, and a spring, wherein the spring is in butt joint between the main end face tooth and the inner wall of the shaft box. The main end face tooth is separated and skids from the auxiliary end face tooth when the preset torque is exceeded and is engaged with the auxiliary end face tooth again under the effect of the spring to achieve transmission. By means of the manufacturing assembly for the thread in the hole, damage to the motor and other circuit elements can be effectively avoided, it is ensured that the tapping work is conducted smoothly, the working efficiency is improved, meanwhile, moving can be conducted, and transporting is facilitated.

The hole female thread of the present invention makes assembly, including bearing and be located at the motor on bearing, drive mechanism, for clamping the fixture of workpiece and for workpiece being carried out the cutter of tapping, described drive mechanism includes axle box and the power transmission shaft being located in axle box, described motor drives cutter to rotate by power transmission shaft, and the bottom of described bearing is provided with roller; Described power transmission shaft includes the driving shaft for being connected and the driven shaft for being connected with cutter with motor, and described driving shaft is connected by sliding mechanism with driven shaft; Described sliding mechanism includes fixing with described driven shaft the secondary end-tooth being connected and is flexibly connected with described driving shaft and can along the main end-tooth of driving shaft axially-movable and spring, described spring is connected between main end-tooth and axle box inwall, and main end-tooth separates with secondary end-tooth when exceeding default torsion to skid and again engage with secondary end-tooth under described spring effect and realizes transmission.
Beneficial effects of the present invention: the hole female thread of the present invention makes assembly, and roller makes this tapping assembly can move, be readily transported;Power transmission shaft is divided into two sections and is connected by the sliding mechanism newly established, when cutter is produced bigger resistance by workpiece, sliding mechanism produces skidding effect, namely when the transmission moment between driving shaft and driven shaft exceeds moment set in advance between main end-tooth and secondary end-tooth, transmission between main end-tooth and secondary end-tooth disengages, to stop transmission process, now motor still autobiography, it is prevented that the damage of motor and other component; To namely can proceed with tapping after removal of obstacle, it is ensured that being smoothed out of tapping operation, improve working performance; Default moment between main end-tooth and secondary end-tooth is then determined by the elastic force of spring, easy to adjust, reliable.
As further improvement, also including lifting mechanism, what described lifting mechanism included being located at described rest base can be unsettled or be supported in the supporting foot that ground makes described roller unsettled; Set up retractable supporting foot, roller and earth surface can be made after packing up supporting foot, it is simple to the movement of tapping machine; Roller can be made unsettled bearing jack-up after putting down supporting foot, it is simple to the location of tapping machine; Supporting foot can put down when using and deposit the load of release roller, and roller is hardly damaged, and maintenance cost is low.
As further improvement, support platform it is provided with between described fixture and bearing, described support platform by be connected vertically move platform and transverse shifting platform forms, described vertically move platform be connected with holder top and can vertically moving along bearing, described transverse shifting platform is connected with clamp base and can along the transverse shifting of bearing; Support platform to carry out transverse direction in bearing plane, vertically move, just with the position adjusting fixture, it is ensured that the precision of tapping.
As further improvement, described drive mechanism also includes gear-box, and the output shaft of described motor is in transmission connection by the gear in gear-box and driving shaft; Gear drive makes the arrangement of motor more diversified, it is achieved the compactedness requirement of this device; Meanwhile, the concrete model of the gear by matching selects also to realize multiple speed change.
As further improvement, the longitudinal direction front side of described bearing is provided with vertical column, and described motor, gear-box and axle box are connected with column each through connecting plate, and described connecting plate can along the axially-movable of column; Connecting plate motion makes the cutter can to workpiece motion s.
