Abstract

The utility model relates to a threading machine, particularly an electric threading machine, which is used for processing a metal pipe or a screw thread which is arranged on the end of a metal rod. The electric threading machine comprises a motor, a gearbox, an electric output shaft, a feeding handle, 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 feeding handle is arranged on the other end of the electric output shaft and the clamping head is arranged on the surface of the base and just face the bolt die fixing head. A travel switch is arranged on the surface of the base and can be positioned between the bolt die fixing head and the clamping head or between the feeding handle and the gearbox, and the travel switch can be electrically connected with the motor which can rotate in a positive and negative mode. The structural design of the electric threading machine is simple and reasonable, the length of the processed screw thread can be accurately controlled, the fraction defective is very low, 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

Electric pipe 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 electric pipe threading machine.

Background technology

The stroke of the electronic output shaft of existing electric pipe threading machine is fully by Artificial Control, even the reach that skilled workman processes is not that to have lacked be exactly to have grown the percent defective height.And the clamping head of such 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 reach can accurately control the electric pipe threading machine easy to operate with clamping head.

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

A kind of electric pipe threading machine, comprise motor, gearbox, electronic output shaft, feed handle, screw die tightens up head, clamping head and base, screw die tightens up the termination that head is located at electronic output shaft, feed handle and be located at another termination of electronic output, clamping head is located at susceptor surface and tightens up head over against screw die, described susceptor surface is provided with the one stroke switch, and travel switch can tighten up between head and the clamping head or feed handle and become and be with between the case at screw die, but the motor of travel switch and rotating electrically connects.

Above-mentioned purpose also can be done further perfect by the following technical programs.

Described susceptor surface is provided with the one stroke switch base, and travel switch is installed on the travel switch seat and can follows the journey switch base and moves.

Described travel switch seating face is provided with one section groove, and groove is parallel with electronic output shaft, and the travel switch lower end is inserted in the groove and by adjustment screw and fixes.

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, the reach that processes can accurately be controlled, and percent defective is extremely low, and clamping head unclamps and clamps easily, and very fast, has improved the operating efficiency of die head threading machine greatly.

The specific embodiment mode

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1, in conjunction with Fig. 1 to Fig. 4, a kind of electric pipe threading machine, comprise clockwise and anticlockwise motor 1, gearbox 2, electronic output shaft 3, feed handle 4, screw die tightens up 5, clamping head 6 and base 7, screw die tightens up 5 terminations that are located at electronic output shaft 3, feed handle 4 and be located at another termination of electronic output 3, clamping head 6 is located at base 7 surfaces and tightens up 5 over against screw die.

Described clamping head 6 comprises runner 60, positioning disk 61, grab tooth 62 for three, spanner dish 63, positioning disk 61 radially equi-spaced apart is established three chutes 64, grabbing tooth 62 for three is embedded in three chutes 64 respectively and can moves along chute 64, spanner dish 63 and positioning disk 61 are embedded side by side in runner 60, spanner dish 63 and runner 60 interlocks, positioning disk 61 is fixed in the runner 60, spanner dish 63 along the circumferential direction is provided with the box thread 65 more than the circle over against three surfaces of grabbing tooth 62, there is male thread 66 on three surfaces of grabbing tooth 62 relative spanner dishes 63, the box thread 65 of spanner panel surface and three public spiral shell mosquitos 66 that grab tooth surface can be meshing with each other, rotating wheel 60 drives 63 rotations of spanner dish, and 63 three of the drives of spanner dish are grabbed tooth 62 and moved radially along positioning disk 61.

Screw die tighten up 5 and clamping head 6 between base 7 surfaces be provided with one stroke switch base 8, the lower end of travel switch 9 is inserted in groove 10 interior adjustment screw 11 location of also passing through on travel switch seat 8 surfaces, the groove 10 of travel switch seating face is parallel with electronic output shaft 3, and travel switch 9 electrically connects with motor 1.Tighten up a distance between 5 by adjustment stroke switch 9 and screw die, can accurately control the length of work piece end thread, when screw die tightens up 5 one a contacting travel switch 9, motor is reversing just.

Embodiment 2, and in conjunction with Fig. 5, the difference of embodiment 2 and embodiment 1 only is that travel switch 9 is located at and feeds between handle 4 and the gearbox 2.
