Description
Technical field
The present invention relates to steel pipe machining tool anchor clamps, specially refer to and be used for " belt conveyor DT II type carrying roller " steel pipe both-end Special Purpose Machine for Processing equipment and use anchor clamps.
Background technology
Existing carrying roller steel pipe both-end endoporus process equipment, its anchor clamps adopt self-centering form clamp structure more, or conical surface form clamp structure positions, and carry out boring or turning processing.Its shortcoming is: steel pipe itself has certain ovality, adopts self-centering or conical surface clamp, and steel pipe is out of shape after clamping and positioning; Steel pipe is adding man-hour two ends for circular; After anchor clamps unclamped, steel pipe recovered ovality, causes processed steel pipe inconsistent in the forward and backward gained processing dimension of clamping; Cause steel pipe two ends endoporus processing column face and external diameter face of cylinder coaxiality error problem bigger than normal, have a strong impact on finished product assembly " a kind of belt conveyor is used carrying roller " footpath and jump beyond target.
Summary of the invention
Technical problem to be solved by this invention is: provide self-adjusting axis flighty and impatient moving clamping device; Restriction steel pipe radial deformation when clamping steel pipe; And adjust steel pipe how much axle center automatically and the lathe axle center is consistent; Make the processing endoporus face of cylinder consistent, reduce the steel pipe radial beat eccentricity with axle center, the outer wall of steel pipe face of cylinder.
The present invention adopts following technical scheme: transfer the unsteady clamping device in axle center, comprising: fixture support frame, driving mechanism, first transmission mechanism, the second transmission mechanism clamp mechanism, floating regulating mechanism, and said fixture support frame is provided with first transmission mechanism, second transmission mechanism; First transmission mechanism also is connected with driving mechanism, and first transmission mechanism is connected with said second transmission mechanism, and second transmission mechanism is connected with clamp mechanism; Also be provided with floating regulating mechanism on the clamp mechanism, said clamp mechanism is provided with two parallel in opposite directions chuck columns, and column is provided with the V-arrangement jaw; Column is connected with support, and the V-arrangement clamp is connected with floating regulating mechanism, and said guiding mechanism is provided with grip block; The clamping face of said grip block is multiple tooth shape clamping area; Said multiple tooth shape clamping area increases the clamping area on the same face of cylinder, avoid stressed concentrating to cause pipe deformation; V-type jaw synchronous all the time symmetry in the anchor clamps left and right sides clamps or unclamps; The anchor clamps center is consistent with the boring head main shaft, and the unsteady grip block of anchor clamps is adjusted automatically, and it is consistent with lathe boring head spindle axis to revise the steel pipe axle center.Control the axiality of steel pipe two ends processing endoporus and external cylindrical surface effectively, reduced the footpath jumping value that steel pipe exists because of ovality own.
Description of drawings
Fig. 1 is the unsteady clamping device structural representation of aligning of the present invention
Among the figure: 1, installing plate, 2, the fixture support frame, 3, tooth bar one, 4, gear; 5, gear shaft, 6, tooth bar two, 7, left chuck column, 8, the V-arrangement jaw; 9, bearing pin, 10, steel pipe, 11, grip block, 12, right chuck column; 13, chuck coupling block, 14, driving block, 15, drive screw, 16, motor.
The specific embodiment
In conjunction with the drawings the present invention is described in further detail below.
As shown in Figure 1, the aligning clamping device that floats comprises fixture support frame 1; Said fixture support frame 1 is connected with installing plate 2, also is provided with gear shaft 5 on the support frame as described above 1, is fixed with gear 4 on the said gear shaft 5; Said gear 4 respectively with tooth bar 1 that is positioned at anchor clamps belows and tooth bar 26 engagements that are positioned at the anchor clamps top, said tooth bar 1 is connected with driving block 14, said driving block 14 is connected with drive screw 15; Said drive screw is connected with motor 16, and said motor 16 is fixed on the fixture support frame 2, and said tooth bar 26 is connected with left chuck column 7; Said left chuck column 7 is provided with V-arrangement jaw 8, and V-arrangement jaw 8 is connected with bearing pin 9, and said bearing pin 9 is connected with grip block 11; Said driving block is connected with chuck coupling block 13 with 14, and said chuck coupling block 13 is connected with right chuck column 12, and said right chuck column 12 has been provided with V-arrangement jaw 8; V-arrangement jaw 8 is connected with bearing pin 9, and said bearing pin 9 is connected with grip block 11.
Operation principle of the present invention is: in the steel pipe process; When needing to realize that anchor clamps are anticipated the position clamping with pipe, steel pipe is delivered on the support of process equipment starter motor 16 through transport; Through screw rod 15; Promote driving block 14 and drive tooth bars 1, chuck coupling block 13, right chuck column 12, gear 4 rotations on tooth bar one 3 gear shaft 5 drive left chuck column 7 and move to left, at left chuck column 7 and right chuck column 12 in opposite directions in the moving process; Steel pipe 10 external diameters at first contact with the inclined-plane of two V-arrangement jaw 8 bottoms; Two V-arrangement jaw 8 contact inclined-planes apply two groups to be frictional force, the active force of symmetry through lathe axle center vertical center line to steel pipe, make steel pipe 10 vertical displacement movements, when how much axle center arrival of steel pipe is put down center line through the machine spindle edema with the heart involved; Be installed in the grip block 11 on the V-arrangement jaw through bearing pin 9 connections; Bearing pin 9 with the installation position is that axis of rotation carries out the low-angle rotation, and steel pipe is produced equivalent and symmetrical frictional force, active force, makes steel pipe 10 under how much symmetrical external force effects, keep overlapping with the machine tool chief axis center.Institute's art motor-driven can also be electronic for other, hydraulic pressure and pneumatic actuation, all belongs to protection scope of the present invention.
