Abstract
The utility model discloses a novel flat mouth tongs which comprises a base, a power source, a push rod, a first tongs mouth and a second tongs mouth, wherein the push rod is movably arranged in the base and one end of the push rod is connected with the output end of the power source, and the push rod is provided with a reversing mechanism which makes the second tongs mouth move synchronously face to face or back to back with the first tongs mouth; the first tongs mouth is fixed with the push rod together and horizontal moves on the base under the push of the push rod. The first tongs mouth of the utility model is driven by the push rod to move on the same direction under the action of the power source, and simultaneously the push rod drives the second tongs mouth by the reversing mechanism to synchronously face to face or back to back move, which realizes that the first tongs mouth and the second tongs mouth simultaneously move always as the same center. The utility model has the advantage of automatic centralization. The utility model enhances work efficiency and the processing precision of parts.
Description
Technical field
The utility model relates to the instrument that clamps part to be processed in a kind of machining, relates in particular to a kind of flat-nose pliers.
Background technology
Existing flat-nose pliers is generally and singly drives flat-nose pliers, and its structure comprises base, regular jaw, moving jaw and drive unit, regular jaw is fixed on the base, during work, moving jaw to the regular jaw translation, clamps part to be processed at last under the driving of drive unit.Because there is size difference in part to be processed, the center that clamps the back part is inconsistent, adds the machining accuracy that can't guarantee part man-hour, then wants each part all to want centering as guaranteeing machining accuracy, influences operating efficiency greatly.
The utility model content
The purpose of this utility model provides a kind of accessory size that is not subjected to influences novel flat-nose pliers in can be automatically fixed.
The technical solution of the utility model is such: a kind of novel flat-nose pliers, comprise base, power source, push rod, first jaw and second jaw, above-mentioned push rod is movably installed in the above-mentioned base and an end connects the output of above-mentioned power source, above-mentioned first jaw and above-mentioned push rod are fixed together and can carry out translation under the promotion of above-mentioned push rod on bases, above-mentioned push rod be provided with can make above-mentioned relatively first jaw of above-mentioned second jaw carry out locking phase to or the changement of opposing translation.
Above-mentioned changement comprises first tooth bar, second rack and pinion, said gear is installed in the above-mentioned base by fixed axis, above-mentioned first tooth bar is located on above-mentioned second jaw, above-mentioned second tooth bar is located on the above-mentioned push rod, and above-mentioned first tooth bar and above-mentioned second tooth bar are meshed with the top and the bottom of said gear respectively.
Above-mentioned power source is a cylinder.
Above-mentioned power source is an oil cylinder.
After adopting such scheme, the utility model is when clamping workpiece, push rod under the driving of power source to promote to the direction of second jaw from first jaw, first jaw is owing to be fixed on the push rod, just also to the second jaw direction translation, simultaneously, under the effect of the changement that first tooth bar, second rack and pinion are formed, second jaw is synchronously to the first jaw translation, until workpiece is clamped.Like this, no matter whether the size of workpiece is consistent, and each time during clamping work pieces, first jaw and second jaw guarantee that all with the translation in opposite directions of identical central synchronous the position of workpiece each processing behind clamping is the center of workpiece.In the time will taking off workpiece, only need to promote by the direction of drive power source push rod to first jaw, at this moment, workpiece is decontroled in the synchronous opposing translation of second jaw and first jaw, the utility model compared with prior art, have the advantage in deciding automatically, improved the machining accuracy of operating efficiency and part greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of novel flat-nose pliers of the utility model, as shown in Figure 1, be provided with base 1, cylinder 2, push rod 3, left jaw 4 and right jaw 5, push rod 3 is arranged in the base 1 and an end connects the piston rod of cylinder 2, left side jaw 4 is fixed together by fastener and push rod 3 and can carrying out translation under the promotion of push rod 3 on base 1, the top of the other end of push rod 3 is provided with tooth bar 31, by fixed axis 11 gear 6 is installed in the base 1, the bottom of gear 6 is meshed with tooth bar 31, the bottom of right jaw 5 is provided with tooth bar 51, and tooth bar 51 is meshed with the top of gear 6.
The utility model is when clamping workpiece, with promotion from left to right, left jaw 4 is owing to being fixed on the push rod 3, just also to right translation under the driving of cylinder 2 for push rod 3, simultaneously, tooth bar 31 promotes gear 6 and is rotated counterclockwise, and gear 6 drives tooth bar 51 and is moved to the left, and is moved to the left thereby drive the right jaw 5 that is fixed together with tooth bar 51, like this, in clamping process, left jaw 4 and right jaw are all the time with a central synchronous translation in opposite directions, until workpiece is clamped.Like this, no matter whether the size of workpiece is consistent, during clamping work pieces, guarantees that the position of workpiece each processing behind clamping is the center of workpiece each time.In the time will taking off workpiece, only need to drive push rod 3 and promote left, at this moment by cylinder 2, right jaw 5 is decontroled workpiece with left jaw 4 synchronous opposing translations, the utility model compared with prior art has the advantage in can deciding automatically, has improved the machining accuracy of operating efficiency and part greatly.
Claims (4)
