It is a kind of for the two circle steel ball auto lock chucks in electric pole reinforcing bar cage seam welding that the utility model provides, and by adopting above structure, promote steel bar sleeve by External Force Acting, conical section can be clamped by steel ball or unclamp reinforcing bar.Be applicable to the Automatic-clamping of various types of reinforcing bar and unclamp, the Automatic-clamping of such as regular screw threads reinforcing bar, indent one-way fashion spiral, polished rod spiral and unclamping, being particularly suitable for the production of electric pole steel reinforcement cage automated job.In preferred scheme, owing to have employed the mode that two ring type steel ball compresses, therefore guarantee that reinforcing bar controls within 3 millimeters at the skidding distance of inside, ensure that the steel reinforcement cage welded out conforms to quality requirements.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is integrally-built cross-sectional schematic of the present utility model.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
In figure: steel bar sleeve 1, locking nut 2, first lap steel ball 3, second encloses steel ball 3', spring 4, sleeve 5, positioning tack board 6, elastic washer 7, nut 8, conical section 9, spacing stage 10, cage guiding portion 11.
Detailed description of the invention
As in Fig. 1 ~ 2, a kind of for the two circle steel ball auto lock chucks in electric pole reinforcing bar cage seam welding, comprise sleeve 5, steel bar sleeve 1 and sleeve 5 are slidably connected, locking nut 2 is fixedly connected with the termination of sleeve 5, is provided with conical section 9, as shown in fig. 1 inside locking nut 2, the inner internal diameter of conical section 9 is comparatively large, and outer end then internal diameter is less.Steel bar sleeve 1 wall is provided with multiple through hole, is provided with steel ball in through hole, steel ball protrudes from the inner and outer wall of steel bar sleeve 1, and when steel bar sleeve 1 slides into certain position along sleeve 5, steel ball is pressed to the inwall of steel bar sleeve 1 by conical section 9.Structure thus, drives steel bar sleeve 1 to slide along sleeve 5 by external force, and steel ball can be made to clamp or unclamp reinforcing bar.
Preferred scheme is as in Fig. 1 ~ 2, and described steel ball is at least two circles along the axis arranged of steel bar sleeve 1, and often circle is at least 3 steel balls.Owing to have employed the structure of two circle steel ball, first lap steel ball 3 as shown in Figure 1 and the second circle steel ball 3'.The axial line of reinforcing bar between two circle steel balls is by the axis being parallel with steel bar sleeve 1, and reinforcing bar can not come off with locking chuck due to the change of angle.
As shown in Figure 2, multiple steel ball is circumferentially uniform.Interlaced arrangement between two circle steel balls.Structure thus, makes steel ball in clamping process, guarantees that reinforcing steel bar bear is even.
As shown in fig. 1, be provided with spacing stage 10 at the outer wall of steel bar sleeve 1, in sleeve 5, be provided with the cage guiding portion 11 of undergauge, between spacing stage 10 and the end face in cage guiding portion 11, be provided with spring 4.Structure thus, makes steel bar sleeve 1 always be tending towards to the left end motion in Fig. 1, thus makes steel ball always be tending towards compressing reinforcing bar.In the inner side of the through hole of installation steel ball, be provided with undergauge structure, can not drop into from through hole in steel bar sleeve 1 to make steel ball.
As in Fig. 1, for being slidably matched between the cage guiding portion 11 in steel bar sleeve 1 outer wall and sleeve 5.Structure thus, guarantees sliding axially steadily reliably between steel bar sleeve 1 and sleeve 5.
Steel bar sleeve 1 front end is provided with expanding mouth.Structure thus, is convenient to insert reinforcing bar.
Sleeve 5 outer wall is provided with stage and is connected with positioning tack board 6.Structure thus, is convenient to accurately locate between locking chuck and miscellaneous part.
Sleeve 5 outer wall is provided with thread segment.Structure thus, is convenient to realize fixed installation by elastic washer 7 and nut 8.
Described steel bar sleeve 1 and sleeve 5 are equipped with through hole vertically.Structure thus, is convenient to exhaust and air inlet in the process of inserting and extracting reinforcing bar.
During use, external member drives steel bar sleeve 1, slides to the right, and the thrust of conical section 9 pairs of first lap steel balls 3 and the second circle steel ball 3' disappears, be convenient to the insertion of reinforcing bar, after reinforcing bar inserts, external member resets, and steel bar sleeve 1 is under the effect of spring 4, slide left, first lap steel ball 3 and the second circle steel ball 3' are pressed to reinforcing bar by conical section 9, and the inscribed circle diameter of first lap steel ball 3 and the second circle steel ball 3' diminishes, thus by reinforcing bar auto lock.Be convenient to carry out welding processing to reinforcing bar, after machining, external member drives steel bar sleeve 1, slides to the right, and the thrust of conical section 9 pairs of first lap steel balls 3 and the second circle steel ball 3' disappears, and is convenient to the taking-up of reinforcing bar.
The above embodiments are only optimal technical scheme of the present utility model; and should not be considered as restriction of the present utility model; the technical scheme that protection domain of the present utility model should be recorded with claim, the equivalents comprising technical characteristic in the technical scheme of claim record is protection domain.Namely the equivalent replacement within the scope of this improves, also within protection domain of the present utility model.
