The small electric threading machine comprises a motor, a gearbox, an electric output shaft, a bolt die fixing head, a clamping head and a base, wherein the bolt die fixing head is arranged on one end of the electric output shaft, the clamping head is arranged on the surface of the base and just face the bolt die fixing head, the electric output shaft passes through the gearbox and a drive shaft and a transmission shaft are arranged in the gearbox. The drive shaft is driven by the motor to rotate, the transmission shaft is driven by the drive shaft to rotate through a speed reducing gear, the other end of the transmission shaft is provided with a transition gear and a gear which is fixed on the electric output shaft is driven by the transition gear to rotate. The structural design of the small electric threading machine is simple and reasonable, a transmission mechanism occurs few faults, the clamping head is convenient for loosening and clamping in a very quick mode and the work efficiency of the threading machine can be increased.

Description

The small-sized electric die head threading machine

Technical field

The utility model relates to a kind of die head threading machine that is used for processing metal pipe or metal bar end screw thread, specifically relates to a kind of small-sized electric die head threading machine.

Background technology

The transmission mechanism complexity of existing small-sized electric die head threading machine often breaks down, and has reduced the operating efficiency of die head threading machine.The clamping head of existing electric pipe threading machine all is to inject in the clamping head rotation swing arm by a swing arm to realize that clamping head unclamps and clamps complicated operation, inconvenience when clamping or unclamping.

Summary of the invention

Therefore, the purpose of this utility model is to provide a kind of drive mechanism the simple and easy to operate small-sized electric die head threading machine of clamping head.

The purpose of this utility model is to realize like this.

A kind of small-sized electric die head threading machine, comprise that motor, gear-box, electronic output shaft, screw die tighten up head, clamping head and base, screw die tightens up the termination that head is located at electronic output shaft, clamping head is located at susceptor surface and tightens up head over against screw die, electronic output shaft passes gear-box, be provided with driving shaft, power transmission shaft in the described gear-box, driving shaft is rotated by motor-driven, power transmission shaft by reduction gearing by the driving shaft driven rotary, the other end of power transmission shaft is provided with transition gear, and transition gear drives the gear rotation that is fixed on the electronic output shaft;

Described clamping head comprises that runner, positioning disk, three grab tooth, spanner dish, positioning disk radially equi-spaced apart is established three chutes, grabbing tooth for three is embedded in three chutes respectively and can moves along chute, spanner dish and positioning disk are embedded side by side in runner, spanner dish and runner interlock, positioning disk is fixed in the runner, the spanner dish along the circumferential direction is provided with the box thread more than the circle over against three surfaces of grabbing tooth, there is male thread on three surfaces of grabbing the relative spanner dish of tooth, and the box thread of spanner panel surface and three public spiral shell mosquitos that grab tooth surface can be meshing with each other.

The utility model structural design advantages of simple, transmission mechanism seldom breaks down, and clamping head unclamps and clamps easily, and very fast, has improved the operating efficiency of die head threading machine greatly.
