Abstract

The utility model discloses a longitudinal welded pipe forming roller repairing clamping device on a machine tool. The longitudinal welded pipe forming roller repairing clamping device comprises a roller repairing spindle mounted in a spindle hole of a machine tool headstock, the left outer surface of the roller repairing spindle is a Morse taper surface matched with a spindle hole, the right outer surface of the roller repairing spindle is also a Morse taper surface matched with an expansion sleeve in a sleeved mode, the outer surface of the expansion sleeve is a cylindrical face, twelve equal-dividing grooves are evenly distributed in the axial direction of the cylindrical face at intervals, the middle of the roller repairing spindle is connected with jaws of a three-jaw chuck through a pin shaft, the end of the roller repairing spindle outside the expansion sleeve is sleeved with a nut, and the outer side end of the roller repairing spindle abuts against a tailstock with a top tip.

Description

ERW molding roller car is repaiied clamping device
Technical field
The utility model relates to a kind of ERW molding roller car and repaiies clamping device.
Background technology
At present, the maintenance of the roll of welded tube production industry adopts the chuck carrying of machine tool itself to clamp mostly.It is that an end face of roll is come on the claw of scroll chuck that the front roll car of improvement is repaiied clamping operation principle, utilize the self-centering principle of scroll chuck, the endoporus of claw stretching roll, because roll is without center center hole, therefore need to assist gland that the endoporus of roll is blocked, install in tailstock top, by rotating handwheel, roll is held out against, eliminate roll and move axially.Because lathe main shaft run-out is in 0.02mm, the circular runout of scroll chuck strengthens along with the increasing of diameter of chuck, if the circular runout of the scroll chuck of diameter 315-400 is in 0.07mm, add the mismatch error of chuck and lathe spindle, in a word, by scroll chuck clamping roll, roll circular runout that car repairs accumulation is beated also in 0.1mm left and right, can not meet the circular runout of Welded Pipe Roller 0.05mm.
Summary of the invention
The purpose of this utility model is to provide a kind of ERW molding roller car to repair clamping device, can effectively reduce the circular runout numerical value of Roller Machining, meets processing request.
The purpose of this utility model is to realize like this, a kind of ERW molding roller car is repaiied clamping device, be included in install in machine tool head box spindle hole repair roll centre axle, the left outer surface of repairing roll centre axle is the Morse's taper surface coordinating with spindle hole, the right side outer surface of repairing roll centre axle is also Morse's taper surface, in this right lateral surface, coordinate and be set with expansion sleeve, the outer surface of expansion sleeve is the face of cylinder, on the face of cylinder, along its axial uniform interval, 12 decile grooves are being set, the middle part of repairing roll centre axle is connected with the claw of scroll chuck by bearing pin, the roll centre shaft end of repairing in expansion sleeve outside is being set with nut, the outboard end of repairing roll centre axle offsets with tailstock by top.
When the utility model uses, promote expansion sleeve and move axially left, because expansion sleeve endoporus is Morse's taper, so that the external diameter of expansion sleeve becomes is large, and with the endoporus swelling of roll.Generally, the Morse's taper of machine tool chief axis coordinates enough transmission turning power.As transmission slip, can carry out transferring power by chuck jaws and trundle, top front identical with improving with the operation of tailstock.The utility model can reduce the circular runout numerical value of Roller Machining effectively, meets processing request.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
A kind of ERW molding roller car is repaiied clamping device, as shown in Figure 1, what be included in machine tool head box 1 spindle hole 2 interior installations repaiies roll centre axle 3, the left outer surface of repairing roll centre axle 3 is the Morse's taper surface coordinating with spindle hole, the right side outer surface of repairing roll centre axle 3 is also Morse's taper surface, in this right lateral surface, coordinate and be set with expansion sleeve, roll 6 is sleeved on expansion sleeve 7.The outer surface of expansion sleeve 7 is the face of cylinder, on the face of cylinder, along its axial uniform interval, 12 decile grooves are being set, the middle part of repairing roll centre axle 3 is connected with the claw 4 of scroll chuck by bearing pin 5, roll centre axle 3 ends of repairing in expansion sleeve 7 outsides are being set with nut 8, and the outboard end of repairing roll centre axle 3 offsets with tailstock 10 by top 9.
