Utility model content
In view of this, for solving the problem, the purpose of this utility model is to provide a kind of reciprocating linear type tapping system, set up sliding mechanism, when workpiece produces larger resistance to cutter, sliding mechanism produces skidding effect, and transmission is stopped, prevent the damage of motor and other component, ensure carrying out smoothly of tapping operation, improve operating efficiency, ensure Tapping Quality.
Reciprocating linear type tapping system of the present utility model, comprise bearing and be located at motor on bearing, transmission mechanism, for the fixture of holding workpiece and the cutter for carrying out tapping to workpiece, described transmission mechanism comprises axle box and is located at the power transmission shaft in axle box, be provided with electric pushrod between described fixture and bearing, described electric pushrod promotes fixture to tool motion; Described motor drives cutter to rotate by power transmission shaft, and described power transmission shaft comprises the driving shaft for being connected with motor and the driven shaft for being connected with cutter, and described driving shaft is connected by sliding mechanism with driven shaft; Described sliding mechanism comprise be fixedly connected with described driven shaft secondary end-tooth, to be 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 is separated with secondary end-tooth when exceeding default torsion to skid and again engage with secondary end-tooth under described spring action and realizes transmission.
The beneficial effects of the utility model: reciprocating linear type tapping system of the present utility model, power transmission shaft be divided into two sections and be connected by the sliding mechanism newly established, when workpiece produces larger resistance to cutter, sliding mechanism produces skidding effect, namely when the carry-over moment between driving shaft and driven shaft exceeds the moment preset between main end-tooth and secondary end-tooth, transmission between main end-tooth and secondary end-tooth is thrown off, to stop transmission process, now motor still autobiography, prevents the damage of motor and other component; Can tapping be proceeded by after removal of obstacle, ensure carrying out smoothly of tapping operation, improve operating efficiency; Default moment between main end-tooth and secondary end-tooth is then determined by the elastic force of spring, easy to adjust, reliable; Drive fixture to put motion to cutter by electric pushrod, be conducive to the stability keeping cutter, ensure Tapping Quality.
As further improvement, be provided with brace table between described fixture and electric pushrod, the output shaft of described electric pushrod is fixedly connected with brace table; By brace table support fixture, the accuracy of clamp movement can be ensured.
As further improvement, described transmission mechanism also comprises 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, realizes the compactedness requirement of this device; Meanwhile, select also can realize multiple speed change by the concrete model of the gear matched.
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 all fixedly connected with column by connecting plate; This is fixedly connected with can be weld or be spirally connected, and reduces the vibrations of motor, ensures that cutter is stablized.
