Abstract
The utility model belongs to field of machining, and in particular to a kind of tooling for the assembly of gas cylinder split ring.Including screw shaft, tapered sleeve, cylindroid helical-coil compression spring, axle sleeve, knurled nut；The split ring assembled will be needed to be inserted in screw shaft, then tapered sleeve, cylindroid helical-coil compression spring are successively inserted in screw shaft, screw shaft is then packed into axle sleeve, screws knurled nut, until split ring is completely embedded into tapered sleeve.At this point, tooling is goed deep into bottle mouth of gas cylinder until axle sleeve blocks bottleneck end face, knurled nut is unclamped at this time, and under the elastic force effect of cylindroid helical-coil compression spring, tapered sleeve releases split ring limit, and split ring automatically springs open, and is packed into the installed position of bottle mouth of gas cylinder.The utility model split ring assembling jig tooling, structure is simple, and manufacturing cost is low, easily operated, has ensured the efficiency of split ring assembly, has avoided the scuffing of gas cylinder inner surface and the damage of split ring.
Description
Technical field
The utility model belongs to field of machining, and in particular to a kind of tooling for the assembly of gas cylinder split ring.
Background technique
Gas cylinder is widely used in the fields such as Aeronautics and Astronautics, weapons, it provides power for the running of pneumatic servo, is steering engine
Critical component.Gas cylinder part split ring is mounted in bottleneck internal annular groove, due to split ring installation site go deep into bottleneck and
Bottleneck diameter is smaller, and traditional frock clamp has no the frock clamp for being very suitable for such assembly, and is easily destroyed bottleneck inner wall
Smooth surface, generate that component assembly is not in place, the disadvantages of damaging, scrapping.
Utility model content
Purpose of the utility model is to solve in gas cylinder split ring assembling process, nothing is suitble to the frock clamp of assembly,
It easily scratches gas cylinder inner wall smooth surface and is filled with the one kind provided the features such as damaging split ring, assembly difficulty for gas cylinder split ring
The tooling matched.
The purpose of this utility model is achieved through the following technical solutions:
A kind of tooling for the assembly of gas cylinder split ring of the utility model, including the compression of screw shaft, tapered sleeve, cylindrical screw
Spring, axle sleeve, knurled nut；Screw shaft is used to connect each part of split ring assembly tooling, is process for hard material
Axis shape structure, one end is boss structure, and one end is helicitic texture；Tapered sleeve is for clamping split ring, for hard material processing
At there is the through-hole by screw shaft thereon；Cylindroid helical-coil compression spring is national standard spring for compressing tapered sleeve, for assembly
When push split ring provide thrust；Axle sleeve is process for hard material, has thereon for covering for tightening and loosening split ring
Enter the through-hole of cylindroid helical-coil compression spring, axle sleeve and screw shaft；Knurled nut, which screws in, screws out screw thread on screw shaft, for being axle sleeve
Spring when tightening, loosening split ring provides pretightning force, is process for hard material, there is the screw thread of cooperation screw shaft thereon；
The course of work
Split ring, tapered sleeve, cylindroid helical-coil compression spring are successively inserted in screw shaft, covered with axle sleeve from screw rod axle thread one end
Enter, knurled nut is threaded into screw thread on axis until split ring is tightened completely by axle sleeve；Then by split ring assembling jig work
Dress fills in gas cylinder mouth, until axle sleeve blocks bottleneck end face, unscrews knurled nut at this time, tapered sleeve is in cylindroid helical-coil compression spring
Under the action of push split ring open, stick into bottle mouth of gas cylinder internal annular groove, complete assembly.
The beneficial effects of the utility model
The utility model split ring assembly tooling, structure is simple, and manufacturing cost is low, easily operated, has ensured split ring dress
The reliability matched avoids the inner surface for scratching bottle mouth of gas cylinder and damage split ring, while also saving a large amount of manpowers, improves
The assembling quality and efficiency of split ring.

Embodiment 1
A kind of tooling for split ring assembly of the utility model, as shown in Figure 1, including screw shaft 1, tapered sleeve 2, cylinder
Spiral compression spring 3, axle sleeve 4, knurled nut 5；
Screw shaft 1 as shown in Figure 2 is used to connect each part of split ring assembly tooling, is process for hard material
Axis shape structure, one end are boss structure, and one end is helicitic texture；；
Tapered sleeve 2 as shown in Figure 3 is process for hard material, has thereon through the logical of screw shaft 1 for clamping split ring
Hole；
Axle sleeve 4 as shown in Figure 4 is process for hard material, has thereon for being inserted in for tightening and loosening split ring
The through-hole of cylindroid helical-coil compression spring 3, axle sleeve 2 and screw shaft 1；
Knurled nut 5 as shown in Figure 5, which screws in, screws out screw thread on screw shaft 1, when for tightening for axle sleeve 4, loosening split ring
Cylindroid helical-coil compression spring 3 provide pretightning force, be process for hard material, have thereon cooperation screw shaft 1 screw thread；
The course of work
Split ring, tapered sleeve 2, cylindroid helical-coil compression spring 3 are successively inserted in screw shaft 1, with axle sleeve 4 from 1 screw thread of screw shaft
One end is inserted in, and knurled nut 5 is threaded into screw thread on axis until split ring is tightened completely by axle sleeve 4；Then split ring is filled
Gas cylinder mouth is filled in clamp fixture, until axle sleeve 4 blocks bottleneck end face, unscrews knurled nut 5 at this time, tapered sleeve 2 is in cylinder
It pushes split ring to open under the action of spiral compression spring 3, sticks into bottle mouth of gas cylinder internal annular groove, complete assembly.Such as Fig. 6 institute
Show.
