Description
【Technical field】
The invention belongs to welding technology field, specifically a kind of weld jig of the short ring parts of clamped one time more than one piece.
【Background technology】
Electron beam welding is as a kind of special welding method, and it possesses, and access for welding is good, and strength of joint is high, welding deformation
The advantages that small, throat thickness is big, and weldable material scope is wide, more and more it is used in the manufacturing process of precision parts.
Because conventional electron beam welding needs to carry out in vacuum chamber, because butt welding is sewed with higher quality requirement and is the ring in high vacuum
Welded under border, be that short ring parts can only weld once every time mostly, workload is very big and production efficiency is low.
【The content of the invention】
To solve problems of the prior art, it is an object of the invention to provide a kind of clamped one time more than one piece becate class zero
The weld jig of part, the fixture can the short ring parts of clamped one time more than one piece carry out electron beam welding, substantially increase production effect
Rate.
A kind of weld jig of the short ring parts of clamped one time more than one piece, including chassis, the axle center on chassis are provided with screw rod, spiral shell
Several transition rings are covered on bar, transition rings include First Transition ring and the second transition rings；
First Transition ring upper and lower surface is equipped with boss, and boss is coaxial with First Transition ring and the lateral wall and part of boss
Miner diameter end inner edge surface gap coordinate；
Second transition rings upper and lower surface is all provided with fluted, and groove is coaxial with the second transition rings and the madial wall and part of groove
Bigger diameter end outer edge surface gap coordinate；
First Transition ring and the second transition rings are arranged alternately；
Screw rod is also arranged with pressing plate in the top of all transition rings, and the axle center of pressing plate offers to be passed through with what screw clearance coordinated
Perforation, the lower surface of pressing plate is set to the lower convex platform being coaxial therewith or low groove, when for lower convex platform when, the lateral wall of lower convex platform and zero
The miner diameter end inner edge surface gap of part coordinates, when for low groove when, the madial wall of low groove and the bigger diameter end outer edge surface gap of part
Coordinate；
Screw rod is connected with nut above pressing plate, and spring shim, spring shim set are provided between nut and pressing plate
On screw rod.
The First Transition ring and the second transition rings are respectively provided with one, and First Transition ring is arranged under the second transition rings
Side, the lower surface of pressing plate is set to the lower convex platform being coaxial therewith.
The First Transition ring and the second transition rings are respectively provided with one, and First Transition ring is arranged on the upper of the second transition rings
Side, the lower surface of pressing plate is set to the low groove being coaxial therewith.
The chassis is connected with screw flight.
The spring shim is dish-shaped pad.
The spring shim is no less than 8.
The material of the First Transition ring and the second transition rings is 1Cr18Ni9Ti.
Compared with prior art, the present invention has the advantages that：
The weld jig of the short ring parts of clamped one time more than one piece of the present invention sets chassis in bottom, and the axle center on chassis is set
There is screw rod, several transition rings are covered on screw rod, transition rings include First Transition ring and the second transition rings；Following table on First Transition ring
Face is equipped with boss, and boss is coaxial with First Transition ring and the miner diameter end inner edge surface gap of the lateral wall of boss and part coordinates；
Second transition rings upper and lower surface is all provided with fluted, and groove is coaxial with the second transition rings and the bigger diameter end of the madial wall of groove and part
Outer edge surface gap coordinates；First Transition ring and the second transition rings are arranged alternately, and when in use, first put one in the upper surface on chassis
Part, then First Transition ring or the second transition rings are placed on the part, then again on First Transition ring or the second transition rings
Place a part, then the second transition rings or First Transition ring placed on the part, be arranged alternately upwards according to this part,
First Transition ring or the second transition rings, so as to realize the short ring parts of clamped one time more than one piece；
Screw rod is also arranged with pressing plate in the top of all transition rings, and the axle center of pressing plate offers to be passed through with what screw clearance coordinated
Perforation, the lower surface of pressing plate is set to the lower convex platform being coaxial therewith or low groove, when for lower convex platform when, the lateral wall of lower convex platform and zero
The miner diameter end inner edge surface gap of part coordinates, when for low groove when, the madial wall of low groove and the bigger diameter end outer edge surface gap of part
Coordinate；
When the part of the top for miner diameter end upward when, be pressed in the part of the top using lower surface for the pressing plate of lower convex platform
Miner diameter end face on, when the top part for bigger diameter end upward when, using lower surface for low groove pressing plate be pressed in it is most upper
On the bigger diameter end end face of the part of side；
Because the axle center of pressing plate offers the through hole coordinated with screw clearance, the lateral wall of lower convex platform and the path of part
Inner edge surface gap is held to coordinate, the madial wall of low groove and the bigger diameter end outer edge surface gap of part coordinate, therefore pressing plate is pressed in most
After the part of top, pressing plate realizes that the axle center of each part and rebound and screw rod and chassis are same by lower convex platform or low groove
Axle, thus can ensure welding when requirement axiality；
Screw rod is connected with nut above pressing plate, and spring shim, spring shim set are provided between nut and pressing plate
On screw rod, by tightening nut, spring shim applies pressure to pressing plate, therefore enables to chassis, screw rod, part, transition
Disk and pressing plate are connected as the entirety of fastening, ensure that the positioning of each part in welding process is set, ensure that welding quality；
Because screw rod can be by thermal stretching, so as to cause the thrust between part, transition disc and pressing plate in welding process
Reduce or disappear, therefore can be constantly chassis, spiral shell in welding process by setting spring shim to can solve the problem that the defect
Bar, part, transition disc and pressing plate apply enough thrusts, therefore can ensure the positioning of each part in welding process, ensure
Welding quality；
The weld jig of the present invention effectively compensate for electron-beam welding equipment work can only weld on a fixture every time
The shortcomings that connecing a part；Saving repeatedly vacuumizes phenomenon caused by repeated clamping part, while operating efficiency is improved
Save because of expense and hold facility time caused by multiple vacuumize, therefore add efficiency, save cost.
Further, the material of First Transition ring and the second transition rings is 1Cr18Ni9Ti so that and it is easy to use, safeguard
Simply, manufacturing cost is low.
