Abstract

The invention discloses a gear pressure-transferring type miniature rapid clamp. According to the clamp, panting pressure is transferred to a rack through a gear, so that the tail parts of an upper clamping plate and a lower clamping plate are propped open through the rack, clamping mouths of the upper clamping plate and the lower clamping plate clamp a circuit board which is required to be fixed, and the pressure is converted into clamping force; under the action of a one-way gear and a one-way hook tooth, the clamping force is preserved; and very small force is used for bumping against a one-way hook tooth handle, so that the clamp can pop open and tear open the circuit board. An easily-worn-out part of the clamp is easy to replace and repair and cannot be abraded easily, so that the clamp is long in service life and low in usage cost; and in an operation process, clamping force can be automatically adjusted, clamping force required by circuit boards with different thicknesses can be reached, and a falling board cannot be propped open easily.

Description

The miniature quick clip of gear pressure transmitting type

Technical field

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

Background technology

On existing plating wiring board production unit, the quick-speed jigs that is used for fixing wiring board is mainly to utilize to depart from the vertex of cam and the characteristic of self-locking and the characteristic of spring are made, although it is fast that they all turn round the operating speed of formula fixture than hand, operate more laborsaving, but their body is all turned round the large of formula fixture than hand, and tooling cost is high; Vulnerable part is easy to wear and be difficult for Replacement and Repair, and work-ing life is short, and use cost is high, also can weaken folder power simultaneously, is directed at board falling damaged line plate; To the wiring board of different thickness, can not automatically regulate its folder power, if can be not clamping when fixing wiring board is too thin, easily board falling.

Summary of the invention

The present invention has overcome the deficiencies in the prior art, provide a kind of gear pressure transmitting type miniature quick clip, make its body small and exquisite, rapid operation is quick, the not easy to wear and easy Replacement and Repair of vulnerable part, and can not change because of wearing and tearing folder power, in operating process, to the wiring board of different thickness, can automatically regulate its folder power, make it the folder power that reaches required, and be difficult for board falling.

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

The present invention is made into train wheel bridge and the lower plate of this fixture with the stainless material of acid-alkali-corrosive-resisting, upper lower plate is done installing side by side by the connection of a rivet; Latter half at train wheel bridge has a frame chamber, at the afterbody of lower plate, has a prong and a frame chamber, and has the default screw hole of installing.A turning handle with half side gear and half of ratchet and a unidirectional hook tooth handle are housed in train wheel bridge frame chamber, half side gear and a tooth bar are 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 is connected by two removable rivets respectively with unidirectional hook tooth handle, be installed in train wheel bridge frame chamber, half of ratchet is assembled on turning handle, when departing from train wheel bridge frame chamber, can separate turning handle.

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 that goes up lower plate is simultaneously closed up and clamped the fixing wiring board of needs, makes pressure convert folder power to.Half of ratchet is pushed the hook tooth of unidirectional hook tooth handle open simultaneously, when reaching required folder power, the operational motion bouncing stops, under the power effect of the top of tooth bar, half of ratchet need to return and clockwise rotate, yet unidirectional hook tooth handle stops half of ratchet to clockwise rotate, thereby changing into folder power, the pressure that makes to bounce preserved.

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

Because the vulnerable part of this fixture is half of ratchet and unidirectional hook tooth handle, they are replacing easy to assemble, reparation all, and 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, increase the service life, and reduce use cost and can not change folder power.

2, in operating process, can automatically regulate its folder power, the wiring board of different thickness can folder power as required be fixed.

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

4, be difficult for flicking board falling.

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

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

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

When bouncing turning handle 1 with hand, half side gear 3 rotates counterclockwise, the pressure that bounces generation is passed to tooth bar 2, tooth bar 2 is strutted the afterbody of train wheel bridge 13 and lower plate 12, make jaws 15 and lower jaws 16 closures, 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 folder power of demand, stops operating, hook tooth 18 and stop half of ratchet 7 to clockwise rotate, thereby preservation folder power is constant.

In the time will tearing plate open, with the very little unidirectional hook tooth of power percussion handle 8, hook tooth 18 and the de-tooth of half of ratchet 7, under the power effect of the top 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.
