For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of for the special-shaped card pin auto lock chuck in electric pole reinforcing bar cage seam welding, comprise sleeve, steel bar sleeve is slidably connected through locking nut and sleeve, locking nut is fixedly connected with the termination of sleeve, conical section is provided with inside locking nut, steel bar sleeve wall is provided with multiple through hole, in through hole, bayonet lock is installed, bayonet lock protrudes from the inner and outer wall of steel bar sleeve, when steel bar sleeve slides into certain position along sleeve, bayonet lock is pressed to the inwall of steel bar sleeve by conical section.

Described bayonet lock top is curved portions, and centre is cylindrical portion, and bottom is prismoid section, forms spacing stage between curved portions and cylindrical portion.

Multiple bayonet lock is circumferentially uniform.

Be provided with spacing stage at the termination outer wall of steel bar sleeve, be provided with the cage guiding portion of undergauge in sleeve, between the end face in spacing stage and cage guiding portion, be provided with spring.

For being slidably matched between cage guiding portion inwall in steel bar sleeve outer wall and sleeve.

Steel bar sleeve front end is provided with expanding mouth.

Sleeve outer wall is provided with stage and is connected with positioning tack board.

Sleeve outer wall is provided with thread segment.

Described steel bar sleeve and sleeve are equipped with through hole vertically.

What the utility model provided a kind ofly by adopting above structure, promotes steel bar sleeve by External Force Acting for the special-shaped card pin auto lock chuck in electric pole reinforcing bar cage seam welding, and conical section can be clamped by bayonet lock 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 unique clamping pin structure, the curved portions at its top is convenient to the conical section good contact with locking nut, cylindrical portion is convenient to slide in the through hole of steel bar sleeve, not easily stuck, prismoid section is beneficial to the insertion of reinforcing bar, and spacing stage can limit the position of bayonet lock in through hole reliably, thus guarantee suitable gap further, facilitate reinforcing bar to insert.The utility model can guarantee that reinforcing bar controls within 3 millimeters at the skidding distance of whole device inside, ensures 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 front view of bayonet lock in the utility model.

In figure: steel bar sleeve 1, locking nut 2, bayonet lock 3, curved portions 31, cylindrical portion 32, prismoid section 33, 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 special-shaped card pin auto lock chuck in electric pole reinforcing bar cage seam welding, comprise sleeve 5, steel bar sleeve 1 is slidably connected through locking nut 2 and sleeve 5, locking nut 2 is fixedly connected with the termination of sleeve 5, conical section 9 is provided with inside locking nut 2, steel bar sleeve 1 wall is provided with multiple through hole, bayonet lock 3 is installed in through hole, bayonet lock 3 protrudes from the inner and outer wall of steel bar sleeve 1, when steel bar sleeve 1 slides into certain position along sleeve 5, bayonet lock 3 is pressed to the inwall of steel bar sleeve 1 by conical section 9.Structure thus, by external force, such as air cylinder driven steel bar sleeve 1 is slided along sleeve 5, and bayonet lock 3 can be made to clamp or unclamp reinforcing bar, and the reinforcing bar in this example is not shown in FIG.

Described bayonet lock 3 top is curved portions 31, and centre is cylindrical portion 32, and bottom is prismoid section 33, forms spacing stage between curved portions 31 and cylindrical portion 32.The curved portions at top is convenient to the conical section good contact with locking nut; Cylindrical portion is convenient to slide in the through hole of steel bar sleeve, not easily stuck; Prismoid section is beneficial to the insertion of reinforcing bar, and spacing stage can limit the position of bayonet lock in through hole reliably, thus keeps suitable gap between the prismoid section guaranteeing bayonet lock 3, further facilitates the insertion of reinforcing bar.

Multiple bayonet lock 3 is circumferentially uniform.Structure thus, makes bayonet lock 3 in clamping process, guarantees that reinforcing steel bar bear is even.

Be provided with spacing stage 10 at the termination 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 bayonet lock 3 always be tending towards compressing reinforcing bar.Owing to forming spacing stage between the curved portions 31 of bayonet lock 3 and cylindrical portion 32, therefore the structure of through hole more simplifies compared to the structure of installation steel ball before, without the need to arranging the structure preventing steel ball from deviating from again, is also more convenient for installing.

For being slidably matched between cage guiding portion 11 inwall 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.This structure, 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, slide to the right, the thrust of conical section 9 pairs of bayonet locks 3 disappears, and is convenient to the insertion of reinforcing bar, after reinforcing bar inserts, external member resets, and steel bar sleeve 1, under the effect of spring 4, is slided left, bayonet lock 3 is pressed to reinforcing bar by conical section 9, 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 bayonet locks 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.
