Abstract
The utility model discloses a kind of laser welding inner support clamp, including Base body, sector rise block, wedge lock bolt, latch, cover board, spring；Pipe fitting to be welded is installed in Base body, tightens wedge lock bolt clockwise by spanner, so that the sector block that rises is prolonged radially uniform expansion using the downward component in inclined-plane, inner support can arrive inner wall surface to be welded simultaneously, achieve the effect that self-centering expansion stretching.After the completion of welding, reuse spanner and rotate tight wedge lock bolt counterclockwise, adjusted by spring self-adapting at latch, by sector rise block rebound retraction, achieve the effect that fast assembling-disassembling.
Description
Technical field
The invention belongs to machinery manufacturing industry technical field and field of automatic welding, specifically a kind of inner support school type uses
Laser welding inner support clamp.
Background technology
Many parts are all made of electron beam welding and laser welding in IC equipments, and the structure of part is thin-wall revolving body zero
Part is needed to being welded at inner ring groove of part, more stringent for welding technique requirement, since laser welding is needed part
Be adjusted to ideal machining state, but thin-walled parts often deform before welding it is larger, if not using inner support structure that cannot protect
Card welding is smoothed out.In addition welding deformation stress is very big, needs the chucking power of interior support mechanism also very big, this just gives
Fixture Design brings certain challenge.
Invention content
The purpose of this utility model is to provide a kind of laser welding inner support clamp, and processing is simple, and packaging efficiency is high, practical
Property is strong, and compression mode is stablized, uniform force and stress distribution is more concentrated reliably, can be obtained in mechanical processing or automatic welding
To application.
To achieve the goals above, the technical solution adopted in the utility model is：
A kind of laser welding inner support clamp, including Base body, sector rise block, wedge lock bolt, latch, lid
Plate, spring；
Base body is boss structure, and middle part is equipped with circular groove, and threaded hole is equipped in groove, and end face is equipped with six intersections
Sliding slot and six triangles are convex stupefied；Sliding slot is provided with circular hole, convex stupefied equipped with threaded hole；
Wedge lock bolt is screwed together in groove；
Sector, which rises, is equipped with waist-shaped hole in the middle part of block, and the sector block that rises is arranged in card slot, and the rise waist-shaped hole of block of sector is equipped with stop
Pin and spring；The sector that spring the makes block bevel end that rises is abutted against with wedge lock bolt wedge face；Annular cover plate is located at pedestal master
On body, cover board be bolted triangle it is convex it is stupefied on.
The beneficial effects of the invention are as follows：
1. the assembling of utility model self-centering expansion mechanism is simple, sector is risen block, latch, spring is installed to pedestal master
On body, cover board and Base body are tightened with M12 soket head cap screws.
2. easy to operate, functional.Wedge lock screw is tightened using die nut, by being threaded into, makes the conical surface
It moves down, is bonded with Base body inner conical surface, to drive the sector block that rises to move radially, reach the effect of self-centering expansion
Fruit.
3. the utility model can meet the turn-milling cutting of slewing parts, welding and school type use.It is thin particular for annular
Wall part, the Auxiliary support of Flexible Deforming Parts prevent stress deformation in processing.Be always ensured that in the welding process weldment with it is interior
Wall is tightly bonded, and arm of force operating distance is most short, is ensured in the case where torsional moment is certain, and stress surface is maximum.
4. the utility model is simple in structure, traditional tooling needs to make hydraulic pressure or air-actuated jaw ensures clamping force, but structure
Complexity involves great expense, and this internal stay tool uses that the cost of material is low, can use common No. 45 steel material, A6061 aluminum alloy materials,
The materials such as 304 steel, highly practical, Vehicle Processing, Milling Machining, welding and assembly process can be used.

Specific implementation mode
With reference to say attached drawing 1-5 and reference numeral to the utility model be further described.
A kind of laser welding inner support clamp, including Base body 1, sector rise block 2, wedge lock bolt 3, latch 4,
Cover board 5, spring 6；
Base body 1 is boss structure, and middle part is equipped with circular groove 7, and threaded hole is equipped in groove, and end face is equipped with six friendships
Pitch sliding slot 8 and six triangles convex stupefied 9；Sliding slot is provided with circular hole, and convex stupefied 9 are equipped with threaded hole；
Wedge lock bolt 3 is screwed together in groove 7；
The sector middle part of block 2 of rising is equipped with waist-shaped hole, and the sector block 2 that rises is arranged in card slot 8, and the rise waist-shaped hole of block 2 of sector is equipped with
Latch 4 and spring 6；The sector that spring 6 makes 2 bevel end of block that rises is abutted against with 3 lozenges of wedge lock bolt；
Annular cover plate 5 is located in Base body 1, and cover board 5 is bolted on triangle convex stupefied 9.
Slewing parts structure is extremely complex, and laser welding annular cover plate, built-in magnet are wanted in inner cylinder middle part position.It is required that
Two weldments uniformly overlap, twice weld seam above and below welding annular cover plate.
Special fixture is installed on laser welder illiciumverum workbench, after being connected with transfer panel, connected components to be welded are installed
Onto fixture, wedge-shaped clamping screw is locked with die nut, the sector block that rises locks downward stress by bolt, radially expands
, it uniformly fits on annular element inner wall to be welded, ensures very close to each other, mechanism band self-locking function, in welding
It will not enough fail because of coupling mechanism force.
