Description
Technical field
The utility model relates to test equipment technology, a kind of set of jaws of more particularly, to automatic flexing tester
Part.
Background technique
In order to make the happy growth of children, in addition to the care and company of household, in daily, we are usually selected as child and mention
For some toys, by toy make child oneself or with junior partner is happy plays.In existing toy art, toy includes cloth
Even toy, anti-raw toy, educational toy, intelligent toy etc..Existing toy is in processing, it is often necessary to composition toy body
Part be filled, as fill lint, metal wire, especially toy joint type component between connection, it is often necessary to pass through
Metal wire is attached, so that toy be kept to have certain mobility.But it, usually can be right during child uses toy
Arm, leg, the limbs of toy are pullled, screw or mouth is stung, so, can screwing and pullling because of transition, the connection that rises that can make makees
Metal wire is broken because of fatigue, to make internal filling expose, or inner wire punctures outside the cloth of toy
Table and extend out to off-balancesheet outside toy, children further be applicable in toy during, children can be caused with actual bodily harm even
Life danger.For child safety, processing and safe handling for toy, existing main standard have the U.S. to carry out
The EN71-1 that ASTM F963 and European Union carry out needs the toy and each component to processing to meet above-mentioned relevant criterion
Carry out dependence test.And it is existing in, for the artificial carry out flexing test that the metal wire that is filled in toy uses, that is, logical
The other end that stationary fixture grips metal wire to be measured is crossed, the other end is clamped by floating holder, is then being matched close angle
Whether scale deflects certain number and detects metal wire and be broken and complete to detect to carry out the deflection of special angle, so needs
Want centainly artificial that could complete to measure accordingly, and labor intensity is big, the consistency of test result cannot be guaranteed.
Therefore, the existing middle tester with the metal wire detection completed by test automatically in toy, such tester pair
In substantially including two parts component: clamping device and swing mechanism, cooperated by clamping device and swing mechanism by metal wire
Clamping note, then cooperate the swing of swing mechanism and complete the flexing and testing fatigue of metal wire.In existing, for swing mechanism pair
Metal wire, which carries out clamping employing mode, to be had: first is that, winding clamping, that is, on one end of metal wire to be measured is wound on swing mechanism
Go up and fixed, fixed to be allowed to opposite swing mechanism, but such mode in swing mechanism swing process it is easier that gold
Belong to and repeat elastic and tension and relaxation at line winding, to cause test result inaccurate；Second is that clamping jaw clamps, that is, pass through two
The end of metal wire is clamped in the clamping jaw of face setting, the clamp or release of clamping jaw, matching, but existing middle using clamping jaw method of clamping
Clip claw assembly be designed as a movable jaw and a stationary jaw, clamped by the relatively fixed clamping jaw of transmission movable jaw or
It unclamps, so needs to carry out the design that centers at the beginning of design using such mode, to ensure by two clamping jaws of transmission
When clamping, two clamping jaws are located in position on the position of setting, thus while just needing to assemble carries out lean and correct assembly, the such folder made
Claw assembly assembly is complicated, using limited.
Utility model content

Component, the clip claw assembly structure simplify, are easy to assembly, correct without complicated positioning, and equipment cost is low.
To solve above-mentioned technical problem, the utility model a kind of technical solution is provided a kind of as follows, clip claw assembly, folder
Claw assembly clamps metal wire to be measured, including rotary swinging arm, deck, clamping jaw seat, drive screw, clamping jaw for automatic flexing tester
Knob and clamping jaw；It is formed with sliding slot on the rotary swinging arm, laterally extends card convex on the deck, the card convex activity is threaded through
Lock in the sliding slot and by locking plate, matching is installed in the deck longitudinally on rotary swinging arm and can move along the chute；Institute
It states clamping jaw seat laterally to install in system in the installation space on the deck, it is opposite that two hands of spiral is formed on the drive screw
Threaded portion and the drive screw be laterally threaded through on the clamping jaw seat, two threaded portions of the drive screw respectively with it is vertical
Two clamping jaws being located on the clamping jaw seat are spirally connected, and the clamping jaw knob is located at one end of the drive screw transverse direction；Rotation
The clamping jaw knob can drive the drive screw to rotate and move towards two clamping jaws laterally and to match clamp or release to be measured
Try metal wire.
It is further described as to above-mentioned technical proposal:
In the above-mentioned technical solutions, the sliding slot is to go to shape sliding slot, and the locking plate is round pie nut, and the locking plate
Pass through screw and the card convex interlocking.
In the above-mentioned technical solutions, the installation space is the groove of indent, and the clamping jaw seat is inlayed in the groove,
The deck upper end and bottom end are formed with through deck screw hole, and each screw hole is implanted into screw and makes screw and the clamping jaw seat spiral shell
It connects, matches the clamping jaw seat and install in system in the installation space on the deck.
In the above-mentioned technical solutions, the U-shaped groove being laterally extended, two inner side edges of U-shaped groove are formed on the clamping jaw seat
On be formed with flange, the end that each clamping jaw is connect with drive screw is formed with upper and lower two and matches in structure with the flange
First groove, two flanges are caught in matched first groove, are flexibly connected each clamping jaw with the clamping jaw seat
And it can be along U-shaped groove transverse shifting.
