Description
Technical field
The utility model relates to a kind of machining equipment, particularly relates to a kind of clamping tool.
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, 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, other end pipe plug is held out against by tailstock centre, 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, by four-jaw chuck or three-jaw self-centering chuck clamping B end flanges, A end holds out against with a dull and stereotyped plug tailstock centre, 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 low cost of manufacture.
The technical solution of the utility model is achieved in that clamping tool, comprises the lengthening self-centering chuck with L shape elongated portion and centering disk; Described centering disk comprises axle, clamp body, spring, gland and at least three support claws; Described clamp body is that front end is protruding, front and back communicate and the disc clamp body of along the circumferential direction uniform at least three through holes; Described support claw is arranged in each through hole of clamp body by spring and gland; Described axle is three sections, the screw-internal thread fit of the leading portion end of thread and clamp body front end projection, and stage casing conical end contacts with three support claws installed in clamp body, and back segment is round end, and after described axle coordinates with clamp body, round end exposes outside.
Further, the round end of described axle is processed into hexagon.
Further, also comprise spanner, with the round end of axle with the use of.
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.
After the utility model adopts said structure, structure is simple, and manufacturing expense is low, handling ease, easy for installation.Add the installation that can eliminate man-hour centre frame, simultaneously after the restriction to lengthening self-centering chuck elongated portion, also eliminate the work of twice clamping, thus substantially increase production efficiency, reduce production economy cost.

Detailed description of the invention
Shown in accompanying drawing 4,5,6, clamping tool of the present utility model comprises lengthening self-centering chuck 8 with L shape elongated portion and centering disk.Described centering disk comprises axle 17, clamp body 13, spring 12, gland 11 and at least three support claws 10.Described clamp body 13 is that front end is protruding, front and back communicate and the disc clamp body 13 of along the circumferential direction uniform at least three through holes.Described support claw 10 is arranged in the through hole of each clamp body 13 by spring 12 and gland 11.Described axle 17 is three sections.The screw-internal thread fit of the leading portion end of thread 15 and clamp body 13 front end projection.Stage casing conical end 14 contacts with three support claws 10 installed in clamp body 13.Back segment is round end 16, and described axle 17 coordinates rear round end 16 to expose outside with clamp body 13
During work, by one end of workpiece elongated portion stretching workpiece 9 inwall lengthening self-centering chuck 8.Again centering disk is put into the inside of workpiece 9 other end.The round end 16 of mandrel 17.Axle 17 moves forward along the axle center of clamp body 13.Support claw 10 outwards mobile thus stretching workpiece 9 inwall under the effect of axle 17 conical end 14 and spring 12.Finally with the top round end 16 withstanding axle 17 of tailstock tool.
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.
As further improvement, the round end 16 of axle 17 described in the utility model is processed into hexagon.
As further improvement, the utility model also comprises spanner, with the hexagon round end 16 of axle 17 with the use of.Other shape can certainly be processed into.To coordinate special spanner, the round end 16 being convenient to center roller 17 rotates.
Lengthening self-centering chuck 8 described in the utility model is preferably three-jaw self-centering chuck or four-jaw chuck.
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 9 inwall 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.
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.
