Description
Technical field
The utility model belongs to screw rod shearing technique field, 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.
Utility model content
The purpose of this utility model is to provide a kind of novel gear type screw rod cutters, to solve in above-mentioned background technique
The problem of proposed.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
The utility model is a kind of novel gear type screw rod cutter, including pedestal, and the base-plates surface is turned by shaft
Dynamic to be connected with 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 and rotation pincers are rotatablely connected, and the grips pincers with rotation pincers coaxial arrangement are additionally provided on the pedestal, the pedestal side is consolidated
Surely there is locating shaft, the pedestal is 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 utility model has the following beneficial effects:
1, the utility model novel gear type screw rod cutter acts on different rule compared to the cutter of lever principle
Screw rod on lattice when, as long as the active force of hand is constant, the power acted on screw rod is exactly continued for constant.And using same
Sample brachium cuts arm, since effect ratio is bigger, so cut the screw rod of same specification, for hand active force with regard to smaller, hand
Feeling of fatigue is with regard to smaller.
2, the utility model is for the screw rod of different size, and in cutting, rotation pincers need the angle opened to be consistent,
And angle when starting effect is also consistent, this is because cutter head is in design, no matter which kind of specification, center is away from being all consistent
's.
3, the utility model places the cutter head of different size together, can avoid the screw rod due to needing to switch different size
And need to frequently replace different cutter heads.
4, the utility model once adjusts the gap between cutter head, after nut check, it is subsequent in operation, be not necessarily to
Often adjustment gap.
5, the utility model devises screw rod bending mechanism, can carry out the bending of different angle, to screw rod with better
Adapt to different installation spaces.
Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.

Slot, pedestal 1 and positioning card 3 can be bolted on work top, and 1 surface of pedestal is rotatablely connected by first rotating shaft 4
There is actuating arm 5,5 rear end of actuating arm is nested and fixed rotation by positioning pin and cuts arm 6, and rotation cuts 6 rear end cap of arm and is equipped with handle 7,
5 front end of actuating arm is connected by meshing transmission by Profile of AT rotation pincers 8, and 5 front end of actuating arm is fixed with Profile of AT A501, rotation
It clamps 8 surfaces and is fixed with the Profile of AT B801 being meshed with Profile of AT A501,1 surface of pedestal passes through the second shaft 9 and rotation pincers 8
Rotation connection, 9 surface of the second shaft are also arranged with grips pincers 10, and 1 side of pedestal is fixed with locating shaft 11, and 10 surface of grips pincers is opened
Equipped with location hole 1001,11 one end of locating shaft cooperates with location hole 1001 positions grips pincers 10, cuts arm 6 by rotation and rotates,
Linkage actuating arm 5 passes through 8 rotation of Profile of AT A501 and Profile of AT B801 driving rotation pincers.
Rotation pincers 8 and 10 surface of grips pincers offer the first jaw A802 and the first jaw B1002, the first jaw respectively
A802 and the first jaw B1002 is a pair of of jaw, is fixed respectively between the first jaw A802 and the first jaw B1002 by bolt
There is one first cutter head 12, two first cutter heads 12 are staggered in parallel relatively；Rotation pincers 8 and 10 surface of grips pincers offer the respectively
Two jaw A803 and the second jaw B1003, the second jaw A803 and the second jaw B1003 are a pair of of jaw, the second jaw A803
And second be respectively fixed with one second cutter head 13 by bolt between jaw B1003, two second cutter heads 13 are relatively parallel staggeredly to be set
It sets；First cutter head 12 and 13 specification of the second cutter head are different, therefore the diameter range that two pairs of cutter heads can shear screw rod is also not
With, it is can guarantee in this way when shearing different-diameter screw rod, suitable cutter head and jaw can be directly selected, and do not have to logical
It crosses and constantly replaces cutter head on a jaw, avoid complex operations, to improve working efficiency, in rotation 8 rotation of pincers, due to
Grips pincers 10 be it is fixed, mutual dislocation, the second jaw can be generated between the first jaw A802 and the first jaw B1002
Mutual dislocation can be generated between A803 and the second jaw B1003, therefore, two pairs of cutter heads on jaw generate staggered relative rotation,
Play shear action, and due to the tangential direction when shearing force of each pair of cutter head is along rotation, and cutter head is to the circle of shaft
The heart away from constant, therefore shearing force be it is invariable, the applied force by the actuating arm 5 of gear engaged transmission is invariable, hand
The pressure applied in shear history be also it is constant, the feeling of fatigue of hand can be reduced in continual work.
