Description
Technical field
The utility model belongs to portable power tools, particularly a kind of pneumatic Nut-setting gun of hydraulic type with Y shape rifle head.
Background technology
Drawing cap is to be exclusively used in to be fixed on sheet member or the pipe fitting to be screwed into for screw and with sheet member or pipe fitting and other members fixed structure mutually.Draw cap to use quite extensively, particularly engage at metal tube in each industrial circle, as bicycle, solid brass bed and steel furniture or the like, all visible and application of drawing cap.
Disclosed now Nut-setting gun is specialized in pipe spare as pipe with Nut-setting gun and is drawn the cap operation, and it is to utilize pullover formed arc piece and pipe fitting applying, can will draw cap closely to be fixed on the pipe fitting by this.And because the day crescent benefit of pipe fitting design, except the design direction that focuses on light weight and thin-walled, consider based on intensity and moulding again, make the cross sectional shape of pipe fitting no longer be confined to circle, and also engender on daily necessities as the pipe fitting in water droplet shape or flat ellipse cross section or the like.Yet this kind has on the pipe fitting that deep camber changes to be desired to set firmly when drawing cap, can occur drawing cap to fail situation as the expection distortion.For this reason, the applicant files an application case number No. 90223336, name is called the structure improved technical scheme of the bent type Nut-setting gun of circle, it has the rifle body, rifle body one end is provided with the drive bar of tool power, driving the bar outer cup is provided with pullover, the projection of pullover outer end has two arcs that are the Y font to hold up arm, two arcs are held up be equipped with between arm and are passed the hole, drive the drive link of bar outer face installing hexagonal section, clip has screw rod on the drive link, screw rod can pass by passing the hole, and on screw rod, be arranged with bearing group in regular turn, spring and moving casing, the movable sleeve piping is sheathed on the screw rod with the perforation that its central authorities were provided, and prominent the establishing in its inboard outer peripheral edges place is the bead of clip in pullover inside, and outer side-line passes by passing the place, hole.
This can draw the rifle body of cap operation to the bent type pipe fitting of circle is the rotary screw design of pneumatic type, system belongs to a kind of light-duty Nut-setting gun, the person of being easy to use grips move operation with hand, its owner will be applied to draw cap again after the number pipe fitting is welded into integral body, after for example the welding of the body frame of bicycle is finished, on the pipe fitting of droplet-shaped, draw the cap operation again, the Nut-setting gun of this pneumatic type rotation, can draw cap at the pipe fitting that the droplet-shaped deep camber changes though be provided with that arc is held up arm on pullover, yet the screw rod rotation of this kind structure Nut-setting gun but is difficult to control the crush stroke of drawing cap to draw, often have too or too late, draw the cap quality to be difficult to grasp thereby cause.
So, disclose the pneumatic Nut-setting gun of hydraulic type as shown in Figure 6 and comprised rifle head 50, screw rod 52, trombone slide 53, drive link 54, sleeve pipe 55, nut 56, stroke adjustment nut 57
Rifle head 50 has external screw thread 501 and provides perforation 51, and external screw thread 501 is locked and established nut 56 and lock in the internal thread of sleeve pipe 55; Stroke is adjusted nut 57 and is located in the sleeve pipe 55; Screw rod 52 is located in the rifle head 50, and the external screw thread 521 of its front end can be locked and draw cap, and 522 of the external screw threads of screw rod 52 rear ends are locked in the internal thread 531 of trombone slide 53, and trombone slide 53 side faces are provided with elongated slot 532; Drive link 54 is arranged in the trombone slide 53, and inserts elongated slot 532 and be inserted in drive link 54 with pin 542, and the stroke of trombone slide 53 horizontal displacements can be adjusted nut 57 by stroke and be controlled, and the turret head 541 of drive link 54 front ends inserts in the hexagon ring of screw rod 52 rear ends.By this, can start trombone slide 53 and drive screw rod 52 horizontal displacement backward, make and the drawing cap to be extruded and be positioned on the pipe fitting of screw rod 52 front end screw locks, the screw rod 52 of the rifle head 50 of the pneumatic Nut-setting gun of this hydraulic type is to withdraw from horizontal shift and rotation to draw cap, and can adjust the crush stroke of drawing cap, precisely because shortcoming is rifle head 50 when drawing the pipe fitting of establishing the deep camber variation, draw the crimp of cap pulling to be difficult to expection, cause and draw the cap braking edge yielding and not docile.
