Abstract

The invention discloses a kind of Gear pressure-transferrintype type miniature rapid clamp, this fixture mainly passes to a tooth bar by gear the pressure bounced, tooth bar is strutted the afterbody of train wheel bridge and lower plate, the jaws of lower plate is made to clamp the wiring board that need fix, thus pressure is changed into grip force, under the effect of a ratchet and unidirectional hook tooth, grip force is preserved, with very little power percussion unidirectional hook tooth handle, this fixture will flick and split out wiring board.The easy Replacement and Repair of vulnerable part due to this fixture, and not easy to wear, the therefore long service life of this fixture, use cost is low; Automatically can regulate grip force in the process of operation, required grip force can be reached to the wiring board of different thickness.And not easily flick board falling.

Description

Gear pressure-transferrintype type miniature rapid clamp

Technical field

The present invention relates to a kind of electroplating device, particularly on electroplating line plate production unit, be used for fixing wiring board and carry out electroplating jig.

Background technology

On existing electroplating line plate production unit, the quick-speed jigs being used for fixing wiring board mainly utilizes the vertex that departs from cam and the characteristic of self-locking and the characteristic of spring are made, although the operating speed that they all turn round formula fixture than hand is fast, operate more laborsaving, but their body all turns round the large of formula fixture than hand, and tooling cost is high; Easy to wear and the not easily Replacement and Repair of vulnerable part, work-ing life is short, and use cost is high, also can weaken grip force simultaneously, is directed at board falling and damaged line plate; Its grip force can not be automatically regulated to the wiring board of different thickness, if can be not clamping when fixing wiring board is too thin, easy board falling.

Summary of the invention

Instant invention overcomes the deficiencies in the prior art, provide a kind of Gear pressure-transferrintype type miniature rapid clamp, make its body small and exquisite, rapid operation is quick, the not easy to wear and easy Replacement and Repair of vulnerable part, and grip force can not be changed because of wearing and tearing, automatically can regulate its grip force to the wiring board of different thickness in operation, make it to reach required grip force, and not easily board falling.

The object of the invention is to be achieved by the following technical programs.

The stainless material of the present invention's acid-alkali-corrosive-resisting is made into train wheel bridge and the lower plate of this fixture, and upper lower plate does installing side by side by the connection of a rivet; Have a frame chamber at the latter half of train wheel bridge, have a prong and a frame chamber at the afterbody of lower plate, and have default installation screw hole.In train wheel bridge frame chamber built with a turning handle with half side gear and half of ratchet and a unidirectional hook tooth handle, half side gear and a tooth bar meshing, tooth bar afterbody has a prong, and join with lower plate afterbody prong, unidirectional hook tooth handle is meshing with half of ratchet under the effect of a spring, turning handle and unidirectional hook tooth handle are respectively by two removable rivet interlacement, be installed in train wheel bridge frame chamber, half of ratchet is assembled on turning handle, can separate turning handle in time departing from train wheel bridge frame chamber.

When bouncing turning handle with hand, half side gear passes to tooth bar bouncing pressure, and tooth bar is strutted the afterbody of upper lower plate, and the jaws simultaneously going up lower plate closes up the wiring board clamped needs and fix, and makes pressure convert grip force to.The hook tooth of unidirectional hook tooth handle pushed open by half of ratchet simultaneously, when reaching required grip force, the operational motion bounced stops, under the top power effect of tooth bar, half of ratchet needs to return to rotate clockwise, but unidirectional hook tooth handle stops half of ratchet to rotate clockwise, thus make the pressure bounced change into grip force to be preserved.

When to dismantle wiring board time, only need very little power percussion unidirectional hook tooth handle, hook tooth and the half of ratchet of unidirectional hook tooth handle take off tooth, and under the top power effect of tooth bar, turning handle sets back, and the jaws of upper lower plate flicks, thus splits out wiring board.

Vulnerable part due to this fixture is half of ratchet and unidirectional hook tooth handle, and their replacings all easy to assemble, reparation, under the lubrication of water, frictional force is each other all very little, not easy to wear, so the long service life of this quick clip, use cost is low.

Can prove by experiment the present invention compared with prior art its beneficial effect be:

1, vulnerable part is not easy to wear, can Replacement and Repair, increases the service life, and reduces use cost and can not change grip force.

2, can automatically regulate its grip force in operation, the wiring board of different thickness can grip force as required be fixed.

3, grip force can not reduce, only relevant with the power of bouncing.

4, not easily board falling is flicked.

5, use cost turns round the low of formula fixture than hand.

Below in conjunction with accompanying drawing, further art is retouched to the present invention.

The present invention does installing side by side primarily of train wheel bridge 13 and lower plate 12 by the connection of dismantled and assembled rivet 11, and rivet 11 connects hole 20 through train wheel bridge and lower plate connects hole 21, the latter half of train wheel bridge 13 has frame chamber 5, the afterbody of lower plate has prong 17 and frame chamber 6, a turning handle 1 with half side gear 3 and half of ratchet 7 has been installed by the connection of a dismantled and assembled rivet 4 in train wheel bridge frame chamber 5, a unidirectional hook tooth handle 8 has been installed by the connection of dismantled and assembled rivet 9, half side gear 3 and tooth bar 2 tooth and, the afterbody of tooth bar 2 has prong 19, prong 19 and lower plate prong 17 are joined, the hook tooth 18 of unidirectional hook tooth handle 8 is meshing with half of ratchet 7 under the effect of a spring, installation screw 10 has been installed at the latter half of lower plate 12, a block 14 is provided with after lower plate jaws 16.

When bouncing turning handle 1 with hand, half side gear 3 rotates counterclockwise, the pressure bouncing generation is passed to tooth bar 2, tooth bar 2 is strutted the afterbody of train wheel bridge 13 and lower plate 12, jaws 15 and lower jaws 16 are closed, and clamping needs fixing wiring board, half side gear 7 is pushed the hook tooth 18 of unidirectional hook tooth handle 8 open and rotates counterclockwise simultaneously, when reaching the grip force of demand, stops operating, hooking tooth 18 stops half of ratchet 7 to rotate clockwise, thus preservation grip force is constant.

When tearing plate open, with very little power percussion unidirectional hook tooth handle 8, hook tooth 18 and take off tooth with half of ratchet 7, under the top power effect of tooth bar 2, turning handle returns to original position, and upper jaws 15 and lower jaws 16 are dehisced to original position.

The first part of train wheel bridge 13 and lower plate 12 except on jaws 15 and lower jaws 16, all make anti-plated copper-clad glue.
