Description
Technical field
The utility model patent relates to the fixture of a kind of automatic welding, particularly relates to a kind of solid propellant rocket
The universal fixturing of closure head assembly automatic welding.
Background technology
Solid propellant rocket closure head assembly is to be made up of with skirt heat exchanger head, and skirt is buckled on heat exchanger head formation
Overlap joint circumferential weld, the then shaping of argon arc welding assembly welding.Compare due to automatic welding relatively manual welding and there is efficiency height, one-tenth
The feature that type is good and attractive in appearance, so selecting argonaut welding to connect.Argonaut welding connects and fixture must be utilized work
Part is fixed on welding turntable, and in welding process, workpiece rotates with turntable and realizes welding fabrication.
Existing closure head assembly automatic welding fixture is as it is shown in figure 1, this kind of fixture is by locating turntable 1, platen 2
Constituting with locking nut 3 totally three parts, locating turntable 1 and platen 2 structure are as shown in Fig. 2, Fig. 3.Use
Time, the step that closure head assembly opening direction is buckled on locating turntable, subsequently platen is assembled to heat exchanger head
Upper end, then fastened by locking nut, finally locating turntable is fixed to welding turntable and gets final product welding.
Existing closure head assembly automatic welding fixture is to utilize closure head assembly big opening end centering to fix, the most not
Needing design to process the frock clamp matched with it with the closure head assembly of size, this clamp structure is the most multiple
Miscellaneous, bulky, handling inconvenience.Closure head assembly kind is the most, and fixture is the most, tool management inconvenience,
Production cost is high.Secondly, Fixture Design, process-cycle are long, it is impossible to meet the manufacturing schedule of factory's new product.
Summary of the invention
The technical problems to be solved in the utility model is to provide the universal clamp of a kind of closure head assembly automatic welding
Tool, to solve the problem that a sleeve clamp can be used for the closure head assembly automatic welding of sizes.
For solving the technical problem existed, the technical scheme that the utility model is used is: a kind of end socket combination
The universal fixturing of body automatic welding, including chassis 4, column 5, location dish 6, depression bar 7 and nut 8, its
It is characterised by: described chassis 4 is connected fixing with location dish 6 by column 5, on the center line of location dish 6
Symmetry has long slot bore；Described depression bar 7 is arranged in the long slot bore of location dish 6, and depression bar 7 can basis
The internal diameter size of the joint 12 of heat exchanger head 9 is slided in the long slot bore of location dish 6 and is adjusted depression bar 7 to location
Distance between the center of dish 6；Described depression bar 7 is by joint 12 end of the heat exchanger head 9 of closure head assembly
Towards after being placed down on location dish 6 and determining position, depression bar 7 is only abutted against the inner cylinder face of 12, makes depression bar
The pressure head 13 on 7 tops compresses closure head assembly, then the screw thread 14 that nut 8 is arranged on depression bar 7 lower end is enterprising
Row fastening.
Typically, after the joint 12 end court of the heat exchanger head 9 of closure head assembly is placed down on location dish 6,
The means such as hand dipping or instrument calibration can be used, by the centre bit in the axle center of closure head assembly Yu location dish 6
Put coincidence, for the ease of the joint 12 end court of the heat exchanger head 9 of closure head assembly being placed down on location dish 6
After, determine that the axle center of closure head assembly overlaps with the center of location dish 6, location of the present invention dish 6
On be scored with different size concentric circles with the center of location dish 6 for the center of circle, assemble at closure head assembly to facilitate
The centering center when location dish 6.
For fixing of convenient different size closure head assembly, location of the present invention dish 6 is provided with 3
Individual step surface, top layer step two through holes of processing, on the center line of bottom two-layer step surface on 4 directions respectively
Process 4 long slot bores.Long slot bore can be easy to the slip depression bar 7 when being installed different size closure head assembly and carry out solid
Fixed.2 through holes on the small stair of top are easy to fixing small size closure head assembly.
Generally joint internal diameter relatively heat exchanger head big opening end much smaller size, and excursion is less, the present invention provides
The universal fixturing of a kind of closure head assembly automatic welding, utilizes this feature peer end to fasten, to necessarily
Closure head assembly in the range of size (joint internal diameter) is the most generally applicable.
Beneficial effect
The present invention provides a kind of closure head assembly automatic welding universal fixturing, utilizes heat exchanger head tip side (osculum
End) feature that change in size scope is less, centering can be carried out by concentric circles, and by slip in long slot bore
Depression bar peer end fastens, and is fixed this end, utilizes this frock to be installed on by closure head assembly certainly
On dynamic welding turntable, workpiece rotates enforcement argonaut welding with turntable and connects, and can be used for the end socket group of sizes
Fit automatic welding.This tool structure is simple, and small volume is easy to loading and unloading, light and handy, uses the lightest,
Reduce different size closure head assembly Fixture Design, labor content.Multiple closure head assembly can be replaced automatic
Weld jig, saves production cost, it is simple to tool management, it is ensured that manufacturing schedule, reaches technological equipment general
The feature changed.
