The utility model relates to a portable tapping machine used for processing pipe fittings or screw threads at the end part of steel reinforcement. The utility model is composed of a machine frame, a motor, a variable speed mechanism, a bearing seat, an output shaft, a three-jaw chuck and a cutting die gliding device. The utility model is characterized in that the output shaft of a belt pulley of the variable speed mechanism is provided with an axial through hole, and the output shaft and the axial through hole have the same center of a circle; a center of the three-jaw chuck on the output shaft of the belt pulley, a central axis of the axial circular through hole of the output shaft of the pulley and the center of the circle of the cutting die are all positioned on the same straight line. The machine has the advantages of simple structure, convenient wrenching, strong maneuverability, convenient operation and high efficiency for processing outer screws, and has significant significance for connecting the pipe fittings or the steel reinforcement in a building trade.

Description

Portable tapping machine

The utility model relates to a kind of thread processing equipment, particularly a kind of process equipment that is used to process pipe fitting or end reinforced screw thread.

At present, the construction cast concrete be used to clamp formwork erection and formwork end reinforced external screw thread or plumbing pipe be installed be used to dock the externally threaded process equipment of pipe end, hitch screw die normally hand-manipulated or rotary cutting lathe.Making screw thread with hand operated hitch screw die wastes time and energy, and working (machining) efficiency is low, because artifact hitch screw die is fragile, and can not guarantee crudy, often is difficult to satisfy the construction needs; Making screw thread with the rotary cutting lathe needs the moulding of repeatedly cutting ability, and the device structure complexity, and Heavy Weight is mobile inconvenient, needs fixing factory building.

The purpose of this utility model is to provide a kind of portable tapping machine at the shortcoming of existing building iron or plumbing pipe end external screw thread process equipment.It can improve reinforcing bar or externally threaded process velocity of pipe end and quality in construction.Simultaneously easy to operate, make easily, and the work mobility strong.

The purpose of this utility model is to realize like this.The above-mentioned formula that gently makes is attacked complete machine by frame 1, motor 2, gear 3, bearing block 5a, 5b, output shaft 4, tripod chuck 6, screw die carriage 7 is formed, motor 2 is housed on the frame 1, gear 3, be characterized in: on above-mentioned frame 1 panel screw die carriage 7 is housed, screw die carriage 7 is by screw die 7a, slide plate 7b, chute 7c forms, screw die 7a is contained on the slide plate 7b, the bottom of slide plate [7b] is contained in the chute 7c and is slidingly matched, the belt pulley 3d output shaft 4 of above-mentioned gear 3 is equipped with and its axially extending bore of concentric mutually, belt pulley 3d output shaft both sides are contained in bearing block 5a, on the 5b upper bearing (metal), belt pulley 3d output shaft 4 one ends are equipped with scroll chuck 6, the center of scroll chuck 6, the axial round tube hole central axis and the screw die 7a center of circle on the output shaft 4 of belt pulley 3d all are on the same straight line.

Operation for convenience, the above-mentioned formula tapping machine that gently makes, carriage 7 one ends of its screw die are equipped with travel switch 11, when the slide plate that screw die 7a is housed is walked the length of needs, slide plate 7b bumps against travel switch 11 retaining blocks that are contained on the chute 7c, travel switch 11 makes motor 2 counter-rotatings, and reinforcing bar or pipe fitting 10 just withdraw from from screw die 7a endoporus.

To the processing of different-diameter screw thread, screw die cover 7x is housed on the slide plate 7b of above-mentioned portable tapping machine screw die carriage 7 for easily, screw die [7a] is contained on the screw die cover [7x].

In order to reach the work mobility strong, move conveniently, guarantee the stability of processing again, roller [8] and support plinth [9] are equipped with in the frame of above-mentioned portable tapping machine [1] bottom, supporting base [9] is made up of screw rod [9b] and supporting member [9a], and rotating screw bolt, supporting member are done corresponding the rising or decline.

The utility model has following advantage compared with the prior art:

1, easy to operate, machining screw speed is made fast more than 10 times of screw thread by hand, and it is convenient to change screw die, also is suitable for processing the screw thread of various outer diameter;

2, simple in structure, in light weight, move conveniently mobility strong;

Above-mentioned advantage has crucial meaning for the connection of reinforcing bar in the building industry or pipeline.

Below by accompanying drawing the novel embodiment of this shirt is described in further detail.

Fig. 1 is a complete machine structure schematic diagram of the present utility model;

Fig. 2 is a screw die carriage schematic diagram of the present utility model.

Fig. 1, shown in Figure 2, the formula tapping machine that gently makes of the present utility model has: frame 1; Motor 2; Gear 3 is made up of belt pulley 3a, 3b, 3d; Output shaft 4; Bearing bracket stand 5a, 5b; Scroll chuck 6; Screw die carriage 7 is made up of screw die 7a, 7b, chute 7c; Roller 8; Supporting base 9 is made up of screw rod 9a, supporting member 9b; Pipe fitting or reinforcing bar 10; Travel switch 11.

During operation, portable tapping machine is equipped with four rolling 8 and moves to the construction site processing stand easily, and rotary screw 9b adjusts supporting member 9a, and supporting base 9 can be with it firmly on the ground.Screw die cover 7x is housed on 7 slide plate 7b of the screw die carriage of frame 1, on the screw die cover 7x screw die 7a is housed.Pipe fitting or reinforcing bar 10 are passed the central through hole of the belt pulley 3d output shaft 4 on bearing bracket stand 5a, the 6b on the frame 1.Pipe fitting or reinforcing bar 10 ends head on the silk aperture of screw die 7a endoporus of screw die carriage 7, screw scroll chuck 6 and clamp reinforcing bar or pipe fittings 10, and screw die 7a center, scroll chuck 6 centers and reinforcing bar or pipe fitting 10 shaft centre lines are on the same straight line.Restart motor 2, through gear 3, pass to belt pulley 3d output shaft 4 by belt pulley 3a, 3b, 3c, 3d, make pipe fitting or reinforcing bar 10 rotations in the output shaft 4, pushing away slide plate 7b pipe fitting or reinforcing bar 10 lightly with hand, its end enters on the screw die 7b hole internal thread on the slide plate 7b and screws out external screw thread.In the time of rotation, slide plate 7b is subjected to screw die 7a to go up the screw thread axial force and moves along chute 7c.When slide plate 7b move on to stroke shape 11 on obstruction piece when collision, travel switch 11 can make motor 2 counter-rotatings, pipe fitting or reinforcing bar 10 are just deviate from from screw die 7a endoporus.
