Abstract
The invention discloses a pipe joint turning fixture which comprises a flange plate, a base, a positioning plate, a pressing block and a wall rack, wherein the flange plate is directly mounted on a main shaft of a lathe; the right-angle base and the right-angle wall rack are positioned and connected onto the outer end surface of the flange plate in parallel; the positioning plate is positioned and mounted on the upward horizontal surface of the base; an inner hole formed in the large end of a workpiece to-be-machined is matched and positioned with the positioning plate. The pipe joint turning fixture is characterized in that the pressing block, which can be adjusted upwards and downwards, is arranged at the extended end of the wall rack, and is V-shaped and coaxial with the main shaft of the matched lathe; the V-shaped surface of the pressing block faces downwards and is tangent to the outer wall of the workpiece, so as to limit the freedom degree of the movement of the workpiece along the axis of the positioning plate; the downward V-shaped surface of the pressing block adopts a symmetrical structure, and comprises an included angle of 900 to 1350 degrees. The pipe joint turning fixture is simple in structure, reliable in clamping, and free of impact of the quality of the outer wall of the workpiece on positioning precision, so that the machining quality is stable, and the production efficiency is high.
Description
Technical field
The present invention relates to a kind of fixture for machine cut processing, specifically, the present invention relates to a kind of pipe joint turning clamp, particularly a kind of pipe joint 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.
Summary of the invention
The present invention, mainly for the deficiencies in the prior art, proposes a kind of pipe joint 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 present invention is achieved through the following technical solutions technical goal.
A kind of pipe joint turning clamp, it is made up of ring flange, base, positioning disk, briquetting and ledge; Wherein ring flange is directly installed on lathe spindle, and on outer face, parallel spaced-apart is located by connecting the base of square and ledge respectively; The workpiece that on described base horizontal plane upward, location and installation positioning disk is to be processed is located to hold greatly endoporus to coordinate with positioning disk; Improvements are: described ledge overhanging end is provided with position can the briquetting of up-down adjustment, and briquetting is V-arrangement, coaxial with the main shaft of supporting lathe, and V-arrangement faces down tangent workpiece outer wall, and restriction workpiece is along the free degree of positioning disk axis movement.
Above-mentioned briquetting V-arrangement face is down symmetrical structure, and its angle is 90
0~ 135
0.
The present invention compared with prior art, has following good effect:
1, with this location and installation, structure is simple, accurate positioning;
2, machining steady quality, production efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 invention will be further described.
A kind of pipe joint turning clamp shown in Fig. 1, it is made up of 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 present invention 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 present invention 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.
