Description
Technical field
The utility model relates to a kind of machining equipment, particularly relates to a kind of clamping tool of processing tube tube kind part.
Background technology
Pipe tube kind part is the class part often run in design.Lifting pipe in borehole shaft driven (centrifugal) pump, submerged pump, submersible pump structure be wherein one example, as shown in Figure 1 to Figure 3, the requirement of its two end flanges seam is coaxial and parallel, the size of processing rear Form and position error directly affects the vibration of pump assembly operation, noise and service life, therefore, the key link be processed in pump manufacture of lifting pipe.
In prior art, in single-piece or small lot batch manufacture, all clamp one end with three-jaw self-centering chuck 3, other end pipe plug 4 is held out against by tailstock centre 5, A is gone out at the two ends car of pipe, B two place, in order to the technological datum face of centering and mounting center frame, datum level requires that surface roughness value is low, but it is not too dark, till car circle, then at B place mounting center frame, after centre frame is adjusted, remove top and pipe plug, complete the processing of B end flanges, unclamp three-jaw self-centering chuck and centre frame, workpiece is touched the pillow, B end flanges is clamped with four-jaw chuck 6 or three-jaw self-centering chuck 3, A end holds out against with dull and stereotyped plug 7 tailstock centre 5, use dial gauge centering A again, B two place.First centering (or detection) B end, then centering A holds, and then check B end.After the centering of two ends, hold mounting center frame at A.And then carry out the processing of A end flanges.Because carry out twice clamping in process, and mounting center frame, in comparatively producing in enormous quantities, use inefficiency, labour intensity is large, and manufacturing cost is high.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides that a kind of structure is simple, simple installation, the clamping tool of the processing tube tube kind part of low cost of manufacture.
The technical solution of the utility model is achieved in that the clamping tool of processing tube tube kind part, comprise two lengthening self-centering chucks with L shape elongated portion and chuck seat, one of them lengthens self-centering chuck and is fixed on chuck seat, chuck seat is fixed on the axle end of chuck seat axle by bearing and bearing gland, the taper hole matched in clearance on the taper shank end of chuck seat axle and support tailstock; During work, lengthen self-centering chuck be arranged on lathe head end by one, another lengthens self-centering chuck and is arranged on tailstock tool by chuck seat, the claw stretching workpiece inner wall respectively of two lengthening self-centering chucks.
Further, described lengthening self-centering chuck is three-jaw self-centering chuck or four-jaw chuck.
Further, the length of described lengthening self-centering chuck elongated portion can get out of the way lathe tool processing end face seam.
Further, described bearing gland is fixedly connected on the axle end of chuck seat axle by screw.
After the utility model adopts said structure, adjustment is simple, easily, fast, handling ease, easy for installation.Add the installation that can eliminate man-hour centre frame, while the claw stretching workpiece inner wall of two ends, the working position of all right automatic capturing workpiece two ends ring flange, by also eliminating the work of twice clamping to the further restriction lengthening position, thus substantially increase production efficiency, reduce production economy cost.
Accompanying drawing explanation
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is the structural representation of processing work in prior art.
Fig. 2 is processing work B end flanges structural representation in prior art.
Fig. 3 is processing work A end flanges structural representation in prior art.
Structural representation when Fig. 4 is the utility model processing work.
In figure: 1, A place 2, B place 3, three-jaw self-centering chuck 4, pipe plug 5, tailstock centre 6, four-jaw chuck 7, dull and stereotyped plug 8, lengthening self-centering chuck 9, workpiece 10, chuck seat 11, axle end 12, taper shank end 13, bearing 14, bearing gland.
Detailed description of the invention
Shown in accompanying drawing 4, the clamping tool of processing tube tube kind part of the present utility model, comprise two lengthening self-centering chucks 8 with L shape elongated portion and chuck seat 10, one of them lengthens self-centering chuck 8 and is fixed on chuck seat 10, chuck seat 8 is fixed on the axle end 11 of chuck seat axle by bearing 13 and bearing gland 14, taper shank end 12 and the taper hole matched in clearance on support tailstock of chuck seat axle; During work, lengthen self-centering chuck 8 be arranged on lathe head end by one, another lengthens self-centering chuck 8 and is arranged on tailstock tool by chuck seat 10, claw stretching workpiece 9 inwall respectively of two lengthening self-centering chucks 8.
After above-mentioned clamping completes, can process workpiece 9 end flange, after completing processing, then adjust excessive come clamping again, complete the processing to workpiece 9 other end flange.
Lengthening self-centering chuck 8 described in the utility model is three-jaw self-centering chuck or four-jaw chuck.
As further improvement, the length of lengthening self-centering chuck 8 elongated portion described in the utility model preferably can be got out of the way lathe tool processing end face seam and is advisable.Described lengthening self-centering chuck 8 is exactly lengthened by the claw of the common scroll chuck of lathe head end or four-jaw chuck, and elongated portion is L shape.Claw stretching workpiece inner wall not processing part during use.
By to the restriction lengthening self-centering chuck 8L shape elongated portion, after workpiece 9 clamping is completed, the processing of two end flanges can be carried out simultaneously.
Bearing gland 14 described in the utility model is fixedly connected on the axle end 11 of chuck seat axle preferably by screw.Certainly the axle end 11 of chuck seat axle can also be fixed on by other mode.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changing or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
