Description
Technical field
The utility model relates to microphone processing technique field, particularly relate to a kind of can the curling mechanism of quick adjustment crimping bar.
Background technology
Microphone generally comprises shell, back pole plate, three-piece, pcb board, need after assembling microphone to carry out crimping or edge sealing operation, namely microphone case openend inwardly being pressed makes its turnup seal, require very high during microphone crimping, require that sealing, waterproof, pcb board are without rocking, this just requires very high to curling mechanism.Common curling mechanism is all a rotating shaft, two symmetrical crimping bars, crimping bar and a stud coaxial rotation, for the product of different model, distance between crimping boom end needs to change, regulate stud just accurately can regulate the distance of two crimping boom ends, after crimping bar position adjustments is accurate, need the clamping screw locking stud by side, the end of clamping screw can contact with stud and apply a moment of torsion to bolt side, this moment of torsion can have influence on the accurate location of stud, present microphone is more and more to small-sized development, during crimping, aligning accuracy between crimping bar and housing requires within ± 0.05mm, in the curling mechanism of prior art, the movable image of stud has been caused to exceed ± 0.05mm during clamping screw locking, thus cause microphone crimp quality to reduce, simultaneously in order to ensure in crimping process, crimping bar is stablized, and it is very tight that clamping screw needs to twist, and the screw thread on stud will be caused like this to be locked bolt head crimp, thus affect the normal regulating of stud.
Summary of the invention
The utility model is located inaccurate to overcome curling mechanism of the prior art when adjustment crimping bar, thus it is not enough to reduce microphone crimp quality, provide a kind of easy to adjust, positioning precision is high, effectively can improve the curling mechanism of microphone crimp quality.
To achieve these goals, the utility model adopts following technical scheme:
A kind of can the curling mechanism of quick adjustment crimping bar, comprise rotating shaft, crimping bar, described rotating shaft one end is fixed with moving block, the bottom center of described moving block is provided with U-lag, the both sides of U-lag form crimping bar contiguous block respectively, described crimping bar contiguous block is provided with coaxial connecting through hole, the axis of described connecting through hole passes the pivot of rotating shaft, the side of described connecting through hole is provided with and regulates gap, described crimping bar contiguous block is also provided with the bolt passing perpendicularly through and regulate gap, the outside of described crimping bar is arranged with bearing, matched in clearance between described bearing and connecting through hole, bearing passes through bolt-locking after loading connecting through hole.When needs regulate crimping distance between tie rods or change crimping bar, first unclamp bolt, now matched in clearance between connecting through hole and bearing, be convenient to crimping bar move freely in connecting through hole or take out, after the adjustment of crimping bar position, clamping screw, when regulating gap to be subject to the pulling force effect of bolt, the hole wall clamping bearing of connecting through hole, thus crimping bar is positioned, in bolt tightening process, crimping bar can not and connecting through hole between relative movement, crimping bar positioning precision is high, thus effectively raises the crimp quality of microphone.
As preferably, described moving block and rotating shaft are integral type structure.Moving block and rotating shaft integral type process, and reduce rigging error between the two, ensure that pivot is between the two completely overlapping, improve crimp quality.
As preferably, the bottom center described moving block being positioned at U-lag is provided with the joint pin coaxial with rotating shaft, and the outside of described joint pin is provided with regulating sleeve, and described regulating sleeve is threaded with between joint pin, the lower end of described regulating sleeve is provided with the adjustment conical surface, and the described adjustment conical surface is provided with scale.Crimping bar Long-Time Service can wear and tear, all need at set intervals to change once, symmetry, the spacing accuracy of two crimping bars require very high, before old crimping bar dismounting, first regulate regulating sleeve, it is made to move along joint pin, until regulate the conical surface to contact with old crimping boom end simultaneously, then dismantle old crimping bar, load onto new crimping bar, the end of new crimping bar with regulate clamping screw after taper-face contact, then regulating sleeve is moved to initial position, whole adjustment process very fast, accurately, reduces the crimping apparatus stand-by period, improves crimping efficiency.
As preferably, the center, outer end of described joint pin is provided with the elastic telescopicing rod coaxial with rotating shaft.Before microphone casing body contacts with crimping bar, elastic telescopicing rod is pressed on pcb board, thus when ensureing crimping, pcb board loads in shell put in place completely, improves the quality of products.
As preferably, the outer end end face of described elastic telescopicing rod is sphere.Elastic telescopicing rod is along with rotating shaft synchronous axial system, and sphere can prevent elastic telescopicing rod scratch pcb board.
Therefore, the utility model has following beneficial effect: when (1) crimping bar regulates, accurate positioning, and precision is high; (2) when crimping bar replacing, adjustment, quick and easy, reduce the crimping apparatus stand-by period, improve crimping efficiency.
