Description

Stannum spool of tape stationary fixture

Technical field

The present invention relates to stannum spool of tape technique for fixing field, particularly relate to a kind of stannum spool of tape fixation clamp Tool.

Background technology

Photovoltaic stannum band is one of very important parts in solar components, and stannum band finished product is wound around volume On axle, when stannum band manufactures, spool needs to be fixed on receipts winding displacement motor, when receiving the work of winding displacement motor, Receiving winding displacement motor shaft rotate and move along a straight line, spool is fixed on receipts winding displacement motor shaft and together turns with it The dynamic purpose reaching retractable cable.Wherein, the stability that spool is fixing is for the retractable cable quality shadow of stannum band Ringing relatively big, in prior art, usual spool is directly to be fixed by nut, but solid with plain nut When determining spool, spool pressure experienced is indefinite, and the elasticity causing spool fixing is different, thus shadow stannum The retractable cable of band, easily causes strand band, causes winding displacement disorder, product bad, wastes resource.

Summary of the invention

It is an object of the invention to the defect overcoming prior art to exist, it is provided that a kind of stannum spool of tape is with fixing Fixture so that fixing of stannum spool of tape is the most firm.

The technical solution adopted for the present invention to solve the technical problems is: a kind of stannum spool of tape fixation clamp Tool, including torque nut, torque nut is arranged in the chamber of torsion circle, the female thread of torque nut Suitable with the external screw thread received on winding displacement motor shaft, torsion circle is arranged the axle body for receiving winding displacement motor shaft The port passed, the periphery circumferentially spaced layout groove of torque nut, shape between adjacent two grooves Become protuberance, be connected with spring by top card between torsion circle and torque nut, one end holding of top card In groove and the end face of this end is inclined-plane, the other end of top card is connected with spring, and layout of spring is in torsion In power circle, the outer surface of described protuberance offers guide groove, and the flute length direction of guide groove is along the circumference of torque nut Direction, the end layout guide block at the place, inclined-plane of top card, guide block and guide groove match.

Beneficial effect: the present invention is driven screwed torque nut by torsion circle, top card and spring, screws Occur that " skidding " phenomenon just realizes consolidating stannum spool of tape to limit torsion circle later and top card to fix.

Detailed description of the invention

Below in conjunction with Fig. 1-Fig. 3, the invention will be further described.

A kind of stannum spool of tape stationary fixture, including torque nut 10, torque nut 10 is arranged in torsion In the chamber of power circle 20, the female thread of torque nut 10 is fitted mutually with the external screw thread received on winding displacement motor shaft Join, torsion circle 20 is arranged the port passed for the axle body receiving winding displacement motor shaft, torque nut 10 Periphery circumferentially spaced layout groove 11, forms protuberance 12, torsion circle between adjacent two grooves 11 It is connected with spring 40 by top card 30 between 20 and torque nut 10, one end card of top card 30 Putting in groove 11 and the end face of this end is inclined-plane, the other end of top card 30 is connected with spring 40, Spring 40 is arranged in torsion circle 20, and the outer surface of described protuberance 12 offers guide groove 121, guide groove The flute length direction of 121 is along the circumferential direction of torque nut 10, the end cloth at the place, inclined-plane of top card 30 Put guide block 31, guide block 31 and guide groove 121 to match.

During use, first the spool being wound with stannum band is arranged on receipts winding displacement motor shaft, then by the present invention Stationary fixture be enclosed within receipts winding displacement motor shaft, promote stationary fixture, until torque nut 10 interior Screw thread encounters the external screw thread stopping receiving winding displacement motor shaft, and then turn clockwise torsion circle 20, because It is connected with spring 40 by top card 30 between torsion circle 20 and torque nut 10, therefore torsion spiral shell Female 10 also can follow torsion circle 20 together rotates clockwise, and torque nut 10 rotates clockwise simultaneously Rotary motion is become linear motion, i.e. torque nut 10 and travels forward along receiving winding displacement motor shaft, Torsion circle 20 constantly advances and oppresses the spool of stannum band, when the spool pressure experienced of stannum band reaches the limit of Time, pressure is reacted on torsion circle 20 by spool, torsion circle 20 again by pressure transmission to torque nut 10, at this moment torque nut 10 axial compressive force is changed into pressure counterclockwise act on top card 30, rotate Time top card 30 tool bevelled ends contact with the protuberance 12 of torque nut 10, described counterclockwise Pressure will force top card 30 disengaging groove 11, and the most again during rotary torsion circle 20, torsion circle 20 will Torque nut 10 cannot be driven to rotate, and top card 30 is followed torsion circle 20 and is rotated, card 30 ends, top Guide block 31 slips in guide groove 121, sends the sound of ' click ', when stationary fixture sends continuous print ' click Click ' sound, and when torsion circle 20 does not readvances, what expression stationary fixture had consolidated secures stannum The spool of band, and fixation pressure is invariable, improves the stability of production, reduces what strand band occurred Fraction defective, improves stannum band and produces fixing quality.

As further preferred version: described torsion circle 20 includes annular ring 21, annular ring 21 Two ends connect cover plate 22 and the vertex of a cone set 23, torque nut 10 is arranged in annular ring 21, cover plate 22 Overlap in 23 chambers enclosed with the vertex of a cone, described cover plate 22 and vertex of a cone set 23 arrange that port supplies The axle body receiving winding displacement motor shaft passes.Cover plate 22 prevents torque nut 10 from dropping, and stationary fixture uses Time vertex of a cone set 23 and one end of stannum spool of tape against cooperation.

Further, the outer surface of described protuberance 12 offers guide groove 121, the flute length side of guide groove 121 To the circumferential direction along torque nut 10, guide block 31 is arranged in the end at the place, inclined-plane of top card 30, Guide block 31 and guide groove 121 match.

Preferably, offer the major diameter passage 211 being connected in annular ring 21 and minor diameter leads to Road 212, the centrage of major diameter passage 211 and smaller diameter passage 212 overlaps and the most annularly encloses 21 Radial direction, spring 40 is arranged in major diameter passage 211, and top card 30 is cylindricality and being arranged in In smaller diameter passage 212, the external port of major diameter passage 211 coordinates sprue 50, and sprue 50 is permissible For detachable parts such as bolts, it is simple to installation and removal.

Should be appreciated that specific embodiment described above is only used for explaining the present invention, be not used to limit Determine the present invention.The obvious change extended out by the spirit of the present invention or variation are still in this Among bright protection domain.
