Abstract

The invention discloses a kind of novel gear type screw rod cutters, are related to screw rod shearing technique field.The present invention includes pedestal, and base-plates surface is rotatably connected to actuating arm by shaft, and actuating arm front end is connected by meshing transmission by Profile of AT has rotation to clamp, and base-plates surface is by shaft and rotates pincers rotation connection, and the grips pincers that coaxial arrangement is clamped with rotation are additionally provided on pedestal.The present invention compared to the cutter of lever principle, act on the screw rod on different size when, as long as the active force of hand is constant, the power acted on screw rod is exactly continued for constant.And arm is cut using same brachium, since effect ratio is bigger, so cut the screw rod of same specification, for hand active force with regard to smaller, the feeling of fatigue of hand is with regard to smaller.

Description

Novel gear type screw rod cutter
Technical field
The invention belongs to screw rod shearing technique fields, more particularly to a kind of novel gear type screw rod cutter.
Background technique
When screw rod is processed, screw thread is often processed on longer bar, and in actual use, generally require the screw rod used Length is shorter, this just needs a kind of shear, and the cutting of longer screw rod is used at shorter screw rod.Screw rod shearing dress Set is to settle down to screw rod using two opposite edges of a knife, be truncated it using shearing force.Screw rod currently on the market is cut Cutting machine is all crocodile shears, and the maximum problem of crocodile shears, is exactly screw rod in shear history, cutter head effect Shearing force on screw rod be with the variation of lever metal plate, active force be it is continually changing, due at the beginning, the effect of lever Ratio is small, and the force value for causing to act on screw rod is smaller, to cut off screw rod, and initial feel force value is long-term to cut with regard to bigger, Hand will be laborious.There are three obvious problems for existing screw rod cutter.First: in the silk of cutting different size When bar, since a screw rod cuts only one secondary cutter head, need ceaselessly to replace cutter head;Second: screw rod is used in shear history Adjusting nut in adjustment cutter head gap was sheared in screw rod, can be generated loosening, be caused to be frequently necessary to ceaselessly adjust spiral shell Mother adjusts cutter head gap.Third: the cutter head of different size is since it is in assembling process, not due to segment design centre distance Unanimously cause, when resulting in the need for the screw rod of cutting different size, the rotation angle needed is inconsistent, and is theoretically acted on The position of power is inconsistent.
Summary of the invention
The purpose of the present invention is to provide a kind of novel gear type screw rod cutters, to solve to be mentioned in above-mentioned background technique Out the problem of.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions:
The present invention is a kind of novel gear type screw rod cutter, including pedestal, and the base-plates surface is rotated by shaft to be connected It is connected to actuating arm, the actuating arm front end is connected by meshing transmission by Profile of AT has rotation to clamp, and the base-plates surface passes through shaft It is rotatablely connected with rotation pincers, the grips pincers with rotation pincers coaxial arrangement is additionally provided on the pedestal, the pedestal side is fixed with Locating shaft, the pedestal are positioned by locating shaft and grips pincers cooperation;
The rotation pincers and grips pincers perimeter surface offer several opposite jaws, are equipped with a pair between each pair of jaw Cutter head, the cutter head use embedded detachable installation in jaw surfaces by bolt;
The pedestal side is equipped with the screw rod bending mechanism rotated coaxially with actuating arm, and the screw rod bending mechanism includes power Armed lever, the actuating arm side are connected and fixed with arm bar, and the arm bar side is rotatably connected to several last items.
Further, it is staggered in parallel relatively between each pair of cutter head on the rotation pincers and grips pincers.
Further, the arm bar is triangular structure.
Further, the pedestal rear end is fixed with fixation and cuts arm, and the actuating arm rear end is fixed with rotation and cuts arm.
The invention has the following advantages:
1, novel gear type screw rod cutter of the present invention acts on different size compared to the cutter of lever principle Screw rod when, as long as the active force of hand is constant, the power acted on screw rod is exactly continued for constant.And use same arm Long cuts arm, since effect ratio is bigger, so cut the screw rod of same specification, for hand active force with regard to smaller, the fatigue of hand It is sympathetic smaller.
2, the present invention is for the screw rod of different size, and in cutting, rotation pincers need the angle opened to be consistent, and open Angle when beginning acts on also is consistent, this is because cutter head is in design, no matter which kind of specification, center is away from being all consistent.
3, the present invention places the cutter head of different size together, can avoid needing due to needing to switch the screw rod of different size Frequently to replace different cutter heads.
4, the present invention is once adjust gap between cutter head, after nut check, it is subsequent in operation, without frequent Adjust gap.
5, the present invention devises screw rod bending mechanism, can carry out the bending of different angle, to screw rod preferably to adapt to Different installation spaces.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
