Abstract
The utility model relates to a portable pipe screwing tool which belongs to pipe processing machinery and implements the screwing by utilizing the principle that the speed of a worm wheel and a worm can be reduced, while the force is increased. The portable pipe screwing tool is composed of a power device, a worm wheel reducer, a screw die combined cutter head, a plane thread locking chuck and movable support legs. The power device can use a motor for drive, and can also use mechanical transmission by manually hand turning. The utility model has the advantages of small size, light weight, simple structure, convenient operation and portability, and is particularly suitable for use in the construction site with frequent installation, maintenance and move.
Description
The utility model relates to a kind of gas pipe thread processing equipment, particularly a kind of portable pipe threading machine.
Existing pipe threading machine, its volume and weight is all bigger, must lift with four-player.Also have pipe hinge plate, it must have attached bench vice table and the pipe pressure clamp of helping, and utilizes lever rotation machining screw, requires great effort very much, and moves also very inconvenience.
The purpose of this utility model is to provide a kind of volume little, simple in structure, easy to operate portable pipe threading machine.
The utility model purpose is achieved in that it by power set, worm reducer, and screw die assembled cutter head, flat thread locking chuck, movable supporting legs are formed.
The utility model purpose flat thread locking plate; Form by locking mother, flat thread plate, flat thread locking head.Flat thread locking chuck body three axis holes are radially arranged, be used for mounting plane screw fastening mandrel, the straight tooth locking head in protruding garden, by wearing Xiao and the flat thread lock shaft combines as a whole, there is flat thread the side of flat thread lock shaft, it and flat thread plate mesh, utilize the wobbler action of the straight tooth locking head in protruding garden, straight tooth locking head in protruding garden and body are nibbled tightly, flat thread locking chuck combines as a whole by screw and worm reducer.
Screw die assembled cutter head in the utility model: by screw die assembled cutter head body, fine setting eccentric shaft, protruding garden screw die positioning disk, protruding garden screw die positioning disk locknut, protruding garden screw die fine setting handle is locked female handle, and the screw die blade is formed.The outer garden of the guide pin bushing of the screw die assembled cutter head body keyway that endwisely slips has slide key in the worm wheel aperture in the worm reducer, and this slide key drives screw die assembled cutter head.Four symmetrical radial slots of screw die assembled cutter head are furnished with four screw die blades, and the positioning disk locknut is pressed into the protruding garden on the screw die positioning disk of protruding garden in the ring-like protruding garden groove of screw die blade side and meshes.Unclamp the female handle of locking, pull protruding garden screw die positioning disk, make screw die be transferred to institute's palpus caliber, pull screw die fine setting handle, utilize the fine setting eccentric shaft to rotate, finely tune feed.
Power set in the utility model can adopt motor-driven; Also can be by artificial rotation.Two kinds of power input forms all connect with the worm shaft of worm reducer.
Portable pipe threading machine of the present utility model utilizes the worm and gear afterburning principle mantle fiber that slows down, can use according to the building site situation, and motor-driven or artificial the rotation, it is little, in light weight, simple in structure that it has a volume, carries advantages such as easy to operate.
With reference to the accompanying drawings, the example of preferably executing to portable pipe threading machine of the present utility model is further described.
Fig. 1 is a kind of portable pipe threading machine of the present utility model, adopts motor-driven.
Fig. 2 is a kind of portable pipe threading machine of the present utility model, adopts manually and rotates.
Fig. 3 a, the structure of the utility model midplane screw-threaded coupling chuck then, schematic diagram, Fig. 3 b are the cut-away views along A-A line among Fig. 3 a.
Fig. 4 a is the structural representation of screw die assembled cutter head in the utility model, and Fig. 4 b is a B-B line cut-away view among Fig. 4 a.
Among the figure, pipe fitting 1, locking female 2, flat thread plate 3, flat thread locking chuck body 4, trip bolt 5, deceleration box 6, worm screw 7, screw die assembled cutter head body 8, fine setting eccentric shaft 9, screw die fine setting handle 10, lock female handle 11, protruding garden screw die positioning disk locking female 12, protruding garden screw die positioning disk 13, screw die blade 14, slide key 15, movable supporting legs 16, worm gear 17, spring collar 18, flat thread lock shaft 19, wear Xiao's 20 turns 21, the straight tooth locking head 22 in protruding garden, worm shaft gear 23, motor gear 24, motor 25, bearing 26, worm shaft crank 27, joint bolt hole 28, bearing baffle 29, bearing baffle screw 30.
Referring to shown in the accompanying drawing, portable pipe threading machine of the present utility model, formed by power set, worm reducer, screw die assembled cutter head, flat thread locking chuck, movable supporting legs.
As shown in Figure 1: be power set by motor gear 24, engages worm gear 23 with by the decelerator that deceleration box 6, worm screw 7, worm gear 17, bearing 26, bearing cap 29, bearing baffle screw 30 are formed on the motor 25 among the figure.
The portable pipe threading machine of another kind of the present utility model, as shown in Figure 2, it is that with the difference of portable pipe threading machine shown in Figure 1 its power set are different, the power set of this machine are artificial hand worm-wheel shaft crank 27, rotary worm 7 and by deceleration box 6, the decelerator that worm screw 7, worm gear 17, bearing 26, bearing cap 29, bearing baffle screw 30 are formed is power set.
The structure chart of the utility model flat thread locking chuck is seen Fig. 3 a and 3b; Flat thread locking chuck, by flat thread lock shaft 19, wear female 2, the turn 21 of Xiao 20, flat thread locking chuck body 4, the straight tooth locking head 22 in protruding garden, locking, flat thread plate 3 is formed.There are three to radially slide the hole on the flat thread locking chuck body 4, are furnished with flat thread lock shaft 19 in the sliding eye.Rotational plane thread plate 3, flat thread lock shaft 19 is done the footpath motion, makes straight tooth locking head 22 in protruding garden and pipe fitting 1 locking, and the straight tooth locking head in protruding garden is eccentric, and pipe fitting engagement in rotation more is tight more.
The structure chart of the utility model screw die assembled cutter head is seen Fig. 4 a and Fig. 4 b, and the screw die assembled cutter head is by screw die assembled cutter head body 8, fine setting eccentric shaft 9, protruding garden screw die positioning disk 13, protruding garden screw die positioning disk locknut 12, screw die fine setting handle 10 in protruding garden is locked female handle 11, and screw die blade 14 is formed.Screw die assembled cutter head body 8 has four symmetrical radial slots to be furnished with screw die blade 14, there is the convex annular garden engagement on protruding garden groove and the protruding garden screw die positioning disk 13 screw die blade 14 sides, unclamp the female handle 11 of locking, rotate protruding garden screw die positioning disk 13, screw die blade 14 is done radial motion, screw die blade 14 can be transferred to pipe fitting institute palpus size, unclamp the female handle 11 of locking, pull screw die fine setting handle 10, fine setting eccentric shaft 9 rotates, and finely tunes feed before the screw die blade 14.
