A kind of electric specialty weldering circuit board auxiliary device
Technical field
The present invention relates to a kind of auxiliary devices more particularly to a kind of electric specialty to weld circuit board auxiliary device.
Background technique
It is electrically the general designation of the subjects such as production, transmission, distribution, use and the electrician's equipment manufacturing of electric energy or engineering field,
In electric specialty, it is often necessary to which soldered circuit board is usually that staff holds electric iron on the other hand, holds tin on the other hand at present
Silk, welds circuit board, in this way, being difficult to control the length that tin silk pulls out, tin silk, which is easy the too long of pull-out, leads to circuit board
Then poor contact is clamped tin silk with tweezers, is welded to circuit board so staff can cut tin silk, grasp in this way
It is inconvenient to make.
Summary of the invention
In order to overcome staff to hold tin silk, circuit board is welded, in this way, being difficult to control the length that tin silk pulls out
Degree, tin silk are easy the disadvantage for excessively causing circuit board contacts bad pulled out, and technical problem of the invention: providing one kind can be compared with
The length that good control tin silk pulls out avoids the too long of tin silk pull-out from leading to the undesirable electric specialty weldering circuit board of circuit board contacts
Auxiliary device.
Implementer's case of the invention is: a kind of electric specialty welds circuit board auxiliary device, include pedestal, supporting leg,
Strut, left-hand tread plate, the first spring, drawstring, cabinet, rack gear, bearing block, shaft, gear, reel, sealing ring and guide sleeve, pedestal top
It is respectively connected with supporting leg at left and right sides of portion, strut is connected among base top, strut top rotary type is connected with left-hand tread plate, and a left side is stepped on
The first spring is connected between plate bottom left and base top, left-hand tread plate top left side is connected with drawstring, the branch of the left and right sides
Leg top is equipped with cabinet, and right part is equipped with resetting-mechanism in cabinet, and rack gear is equipped on resetting-mechanism, and drawstring passes through the bottom of box
Left side is simultaneously connect with rack gear bottom end, and rear side left part is equipped with bearing block in cabinet, and shaft, shaft rear portion peace are equipped in bearing block
Equipped with gear, wheel and rack engagement, shaft passes through cabinet front left part, and shaft front end is equipped with reel, cabinet front left part
It is connected with sealing ring, shaft is contacted with sealing ring inner wall, and cabinet front lower left quarter is equipped with guide sleeve.
Optionally, resetting-mechanism include elastic slice, right-hand tread plate, bracing wire, sliding rail, sliding block, second spring, pulley, n shape plate,
Guide rod and third spring, for the connection of base top right side there are two elastic slice, two elastic slices are all located at the left of right side supporting leg, two bullets
Piece top is connected with right-hand tread plate, and right-hand tread plate top right side is connected with bracing wire, and right part is vertically-mounted in cabinet sliding rail, slides on sliding rail
Dynamic formula is equipped with sliding block, and second spring is connected between slider top and rail tips, and right side central is equipped with pulley in cabinet, sliding
N shape plate is connected on the left of block, n shape plate left side central portion is provided with guide hole, is equipped with guide rod in guide hole, is drawstring through on the right side of the bottom of box simultaneously
Around pulley, bracing wire is connect with guide rod right end, and guide rod left end is connect with rack gear lower right side, and the two sides up and down on the left of n shape plate are equal
It is connected with third spring, two third spring left ends are all connect with rack gear right side.
When needing soldered circuit board, one end of tin silk on reel, is then passed through guide sleeve, such as by tin filament winding by staff
Fruit needs longer tin silk, and staff firmly steps on downwards left-hand tread plate, and the first spring is compressed, and left-hand tread plate is swung by downwards
Drawstring band carry-over bar moves down, to rotate clockwise with moving gear, and then shaft is driven to rotate clockwise, reel is suitable therewith
Hour hands rotation, releases longer tin silk, staff can hold tin silk soldered circuit board.It is welded after circuit board, works
Personnel control resetting-mechanism engages rack and pinion not, then unclamps left-hand tread plate, under the action of the first spring left-hand tread plate to
Upper swing, drawstring are relaxed, and rack gear resets upwards, then control resetting-mechanism make rack and pinion engage, if necessary to compared with
Short tin silk, staff gently step on downwards left-hand tread plate, can release shorter tin silk.It so, it is possible to step on according to demand
Left-hand tread plate avoids the too long of tin silk pull-out from causing circuit board contacts bad so as to preferably control the length of tin silk pull-out.
When rack gear moves down, n shape plate is driven to move down by guide rod, to move down with movable slider, second
Spring is compressed.After welding circuit board is good, staff steps on downwards right-hand tread plate, and elastic slice is compressed, and right-hand tread plate is to moving down
Dynamic to drive guide rod to move right by bracing wire, rack gear moves right therewith, and third spring is compressed.When rack and pinion does not engage
When, staff unclamps left-hand tread plate, and left-hand tread plate is swung up under the action of the first spring, and drawstring is relaxed, in second spring
Under the action of sliding block move up, rack gear moves up therewith, and staff can unclamp right-hand tread plate, right under the action of elastic slice
Pedal resets upwards, and bracing wire is relaxed, and rack gear is moved to the left under the action of third spring, engages rack gear with gear again,
So as to facilitate next soldered circuit board.
By the way that firmly longer tin silk can be released by stepping on left-hand tread plate downwards, gently stepping on left-hand tread plate downwards can release the present invention
Shorter tin silk, so, it is possible to step on left-hand tread plate according to demand, so as to preferably control the length of tin silk pull-out, avoid
The too long of tin silk pull-out causes circuit board contacts bad;It can make tooth bar resets by resetting-mechanism, so as to facilitate next time
Soldered circuit board.
