Description
Technical field
The utility model relates to a kind of axial workpiece deformation correcting devices, and in particular to one kind can be widely used in various
The device that bending deformation of the axial workpiece after machining and heat treatment is corrected.
Background technique
The machining apparatus such as lathe, grinding machine are when processing longaxones parts and longaxones parts pass through heat treatment procedure
Afterwards, since the variation of its material internal metallographic structure causes stress to redistribute, the axis of part is made bending deformation occur.If
The processing of later process is just carried out without overcorrection, often because deflection is greater than machining allowance, will lead to the certain positions of part
It can't process and come and generate and scrap；And later process of giving excessively increases surplus, can make later process (as being ground) surplus mistake
It is big and uneconomical and be processed part by the rigidity layer that heat treatment is formed to reduce quality and influence to use.Therefore, hot
The part that later axial workpiece and machining need to reach accurate Geometrical Tolerance Principle is handled, it will be by using correction
Device carries out primary or straightening for several times.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of axial workpiece deformation
Apparatus for correcting can align the axial workpiece being placed under the pressure head of screw rod lower end by the boosting function of screw, thus
The part of bending deformation is caused to repair machining and heat treatment etc..
Technical solution: in order to solve the above technical problems, the axial workpiece deformation correcting device of the utility model, including place
The support base and rack of axis to be corrected are equipped with nut in the rack, and the shaft shoulder two sides of nut are separately installed with bearing, bearing
It is fixed on the rack by upper cover and lower cover, the screw rod of adaptation is equipped in nut, screw rod is equipped with keyway, and screw rod passes through key and lower cover
Connection, is equipped with turntable in the upper end of cover board, the circumferential direction of turntable is equipped with several handles, and turntable is fixedly connected with nut；It is logical
Handle rotation is crossed, nut rotation is driven, so that screw rod be driven to move down along keyway, the pressure head of screw rod lower end withstands axis to be corrected, will
Axis correction.
Preferably, the nut is connect by pin shaft with turntable.
Preferably, the bearing at the nut both ends is mounted on the rack by upper cover and lower cover respectively, upper cover and lower cover
It is fixed by screws in rack respectively.
Preferably, the support base is equipped with the V-shaped groove for being used to support axis to be corrected.
Preferably, the keyway is straight trough up and down, the key and its sliding fit being fixed in lower cover
Preferably, the thread form of the screw flight uses rectangular thread, the corrective force of screw rod apical axis can be greatly enhanced.
The utility model has the advantages that the axial workpiece deformation correcting device of the utility model, using one group of bolt and nut pair, and in screw rod
Slot in be provided with key, limit the rotation of screw rod, make screw rod that can only realize the movement of up and down direction, by the increasing of screw
Power effect, can align the axial workpiece being placed under the pressure head of screw rod lower end, to cause to machining and heat treatment etc.
The part of bending deformation is repaired.This deformation correcting device can be widely used in various machinings and heat treatment etc. and produce
Cheng Zhong.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of axial workpiece deformation correcting device of the utility model, including rack 7, in the hole of rack 7
Nut 4 is housed by one group of bearing 11, screw rod 3 is by thread in the screw hole of nut 4.Turntable is housed in the outer circle of nut 4
5, nut 4 is linked together with turntable 5 by several pin shafts 2；One group of handle 6 has been evenly arranged in the outer circle of turntable 5.Bearing 11
It is fixed by upper cover 1 and lower cover 12, the hole of lower cover 12 is provided with key 8, and the another side of key 8 is mounted in the elongated slot of 3 outer circle of screw rod
In.
In the present embodiment, the pedestal of rack 7 is placed on work top, and 7 hole of rack is provided with one group of bearing 11, nut 4
The shaft shoulder is packed between bearing 11, outer circle is placed in the hole of bearing 11.For screw rod 3 in the screw hole of nut 4, screw rod 3 and nut 4 are logical
Thread engagement is crossed, turntable 5 is housed in 4 outer circle of nut, one group of pin shaft 2 is threadedly secured on turntable 5, and the end of pin shaft 2 is inserted
In the outer circle for entering nut 4, turntable 5 is made to be fixed together with nut 4, one group of handle 6 is uniformly housed in 5 outer circle of turntable.1 He of upper cover
Lower cover 12 is mounted on the upper and lower end face of 7 inner hole of rack by screw respectively, limits to bearing 11, fixed dress in 12 hole of lower cover
There is key 8, the another side of key 8 is in the elongated slot of 3 outer circle of screw rod.2 support bases 9 have been placed in the upper surface of 7 pedestal of rack, correction
The both ends of axis 10 are respectively placed on support base 9.
The present embodiment drives turntable 5 with rotary motion is made at work, when nut 4 passes through rotating handle 6, due to screw rod 3
Screw thread pair is formed with nut 4, so screw rod 3 also moves；Due to being provided with key 8 in the straight trough of screw rod 3, screw rod 3 is limited
Rotation, make screw rod 3 that can only realize the movement of up and down direction, can be to being placed in 3 lower end of screw rod by the boosting function of screw
Curved axis 10 to be corrected is aligned under pressure head, since the thread form of screw flight uses rectangular thread, can greatly enhance spiral shell
The corrective force of bar apical axis.
