Abstract
The utility model discloses a kind of flange positioning clamping devices.The utility model is by cam handle, straight pin, circlip, pull rod, nut, screw-shaped at component, and screw one end of two or more components (quantity is depending on flange size and required clamping force size) is inserted into the symmetrical bolt hole of flange assembly, two flanges are made to complete coarse positioning, and uniform force after clamping.Then inserted block is put down in the gap for adjusting loose cam handle to make screw and flange assembly wherein one side.Last rotating eccentricity cam handle, clamps flange assembly, being capable of necessary requirement so that reaching.Flange positioning clamping device provided by the utility model realizes the fast assembling-disassembling between two flanges, and compact structure is not necessarily to spanner, easy to operate, can debug, versatile suitable for the flange of various different size models.
Description
Technical field
The utility model relates to a kind of positioning clamping device, in particular to a kind of positioning clamping device of two flanges.
Background technique
It generally requires to be sealed it pressurization in the strength test of pipe fitting and flange welding part, wherein many methods can be related to
Dismounting between orchid.Fixation is generally clamped using bolt and nut between current two flange, dismounting is not easy, and it is time-consuming and laborious,
Therefore it needs to improve.
Summary of the invention
Accumulation and technology of the utility model based on long term production experience are groped, and a kind of flange positioning clamping is provided
Device specifically adopts the following technical scheme that
A kind of flange positioning clamping device.It includes cam handle, straight pin, circlip, pull rod, nut, screw, inserted block.
Described cam handle one end is cam structure, interstitial hole and excircle configuration decentraction；The straight pin is equipped with jump-ring slot；
Described pull rod one end is equipped with internal screw thread；The cam handle is fixed by straight pin connecting rod with circlip；The screw is matched
It closes and pull rod one end and extension elongation can be adjusted by nut.
Compared with originally positioning clamping flange using bolt and nut, the utility model has the beneficial effect that this is practical new
Type clamping device passes through bolt hole using the pull rod and is positioned, efficient and convenient；Utilize cam handle rotation and inserted block
It is clamped, is not necessarily to spanner, it is convenient for disassembly and assembly, save the time；The nut adjustable screw extension elongation, to be applicable in various methods
Orchid clamps, versatile.
Detailed description of the invention
Figure of description is axis side diagrammatic cross-section when the utility model is used.
In figure: 1- cam handle, 2- straight pin, 3- circlip, 4- pull rod, 5- nut, 6- screw, 7- inserted block, 8- flange group
Part.
Specific embodiment
The embodiments of the present invention is specifically described with reference to the accompanying drawings of the specification:
A kind of quick-speed jigs of pipe fitting strength test, cam handle 1 and pull rod 4 are passed through as shown in Figure of description
Straight pin 2 is connected, and is fixed by circlip 3；Nut 5 and screw 6 are connected to 4 screw thread one end of pull rod again, screw is adjusted by nut 5
6 extension elongations are to adapt to the thickness of flange assembly 8；Then by the bolt hole of 6 one end of the screw of said modules insertion flange assembly 8
In, carry out coarse positioning.Then inserted block 7 is inserted into the gap of screw 6 and the formation of 8 lower surface of flange assembly, prevents screw from pulling back
After skid off.Screw 6 is set to pull back to play positioning clamping action to flange assembly 8 finally by rotation cam handle 1.
Quick-speed jigs provided by the utility model are applied equally to similar flanged joint, and the occasion for needing to dismount.This
Utility model structure is simple, and manufacturing cost is low, simple to operate, versatile, has been used for production practices, and implementation result is good
It is good.
