Abstract
The utility model discloses a kind of right angle reducing elbow small end turning clamp, it comprises ring flange, base, positioning disk, briquetting and ledge.Described ring flange is directly installed on supporting lathe spindle, and on outer face, parallel spaced-apart is located by connecting the base of square and ledge respectively.Location and installation positioning disk on described base horizontal plane upward, workpiece to be processed is located to hold greatly endoporus and positioning disk shoulder upward to coordinate.Described ledge overhanging end is provided with the briquetting of upper and lower position adjustable, the briquetting of V-arrangement and the main shaft of supporting lathe coaxial, the tangent workpiece outer wall in V-arrangement face down, realizes restriction workpiece along the free degree of positioning disk axis movement.This practical new construction is simple, reliable clamping, and positioning precision is not by the impact of workpiece outer wall quality, therefore crudy is stablized, and production efficiency is high.
Description
Technical field
The utility model relates to a kind of fixture for machine cut processing, and specifically, the utility model relates to a kind of pipe joint turning clamp, particularly right angle reducing elbow small end turning clamp.
Background technology
Pipeline break-in in industry pipe network just can must be achieved by elbow connection.In engineering, pipeline right angle turns to for many, and this elbow bend majority is reducing pipe, and namely one end bore is large, and other end bore is little.This kind of right angle reducing elbow is curved body, and it is perpendicular and put to add two end interfaces, therefore need distinguish machining interface.Because right angle reducing elbow large end outer wall is relatively regular, the industry generally adopts universal scroll chuck to locate the large end of clamping right angle reducing elbow, and makes corresponding machining.This location structure is simple, reliable clamping, can accomplish Batch Cutting.But the right angle reducing elbow of carrying high pressure has very high-precision requirement to wall thickness dimension, according to existing this outer wall location structure, be subject to the impact of outer wall salient point and produce corresponding position error, unnecessary work must be caused to give up.
Utility model content
The utility model, mainly for the deficiencies in the prior art, proposes a kind of right angle reducing elbow small end turning clamp, and it is a kind of location structure being positioning datum with the large end endoporus of right angle reducing elbow, this location structure is simple, reasonable, easy for installation, accurate positioning, is convenient to machining.
The utility model is achieved through the following technical solutions technical goal.
Right angle reducing elbow small end turning clamp, it comprises ring flange, base, positioning disk, briquetting and ledge.Described ring flange is directly installed on supporting lathe spindle, and on outer face, parallel spaced-apart is located by connecting the base of square and ledge respectively.Location and installation positioning disk on described base horizontal plane upward, workpiece to be processed is located to hold greatly endoporus and positioning disk shoulder upward to coordinate.Its improvements are: described ledge overhanging end is provided with the briquetting of upper and lower position adjustable, the briquetting of V-arrangement and the main shaft of supporting lathe coaxial, the tangent workpiece outer wall in V-arrangement face down, realizes restriction workpiece along the free degree of positioning disk axis movement.
The V-arrangement face down of briquetting described in said structure is symmetrical structure, and its angle is 90
0~ 120
0.
The utility model compared with prior art, has following good effect:
1, the large end endoporus of workpiece fine finishining, with this location and installation, structure is simple, accurate positioning;
2, workpiece is reliably located, and machining steady quality, production efficiency is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Right angle reducing elbow small end turning clamp shown in Fig. 1, it comprises ring flange 1, base 2, positioning disk 3, briquetting 4 and ledge 5.Described ring flange 1 is basic part, and it is directly installed on supporting lathe spindle, forms the structure rotated with main shaft.Ring flange 1 end face is outwardly plane, and parallel spaced-apart is located by connecting the base 2 of square and ledge 5 on this plane.First location and installation positioning disk 3 on base 2 horizontal plane upward, positioning disk 3 is provided with locating shoulder, and this shoulder equals the large end hole size of workpiece to be processed 6.Actually add man-hour, the large end endoporus that workpiece 6 to be processed is shaped with finish turning and positioning disk 3 upward locating shoulder coordinate and locate.This location structure makes workpiece 6 reliably be located, and this positioning datum overlaps with design basis.In order to limit the free degree of workpiece 6 along the movement of positioning disk 3 axis, the utility model is provided with the briquetting 4 of upper and lower position adjustable at ledge 5 overhanging end, and V-arrangement briquetting 4 used is coaxial with supporting lathe spindle.In the present embodiment, the V-arrangement face of briquetting 4 is symmetrical structure, and its angle is 120
0.Downward adjustment briquetting 4 can realize workpiece pressing 6, and in the process compressed, briquetting 4 V-arrangement face tangent workpiece 6 outer wall down, transmits thrust on the one hand, and restriction workpiece 6 is along the free degree of positioning disk 3 axis movement on the other hand.
The utility model adopts accurately machined large end Internal hole positioning, and this location structure is simple, and positioning precision is not by the impact of workpiece 6 outer wall quality.Due to shoulder accurate positioning, reliable clamping, is conducive to right angle reducing elbow small end turnery processing, therefore crudy is stablized, and production efficiency is high.
