The invention has the beneficial effects that the structure of the complete set of tool is compact; the selection of various gaps is appropriate; a small push force is adopted to finish the installation of a larger O-shaped ring; and the tool can be operated by a single person, thereby better achieving precise installation of the O-shaped ring of a large specification. The installation tool has the advantage of reliable performance, is convenient to use and has no damage to the O-shaped ring.
Description
Technical field
The present invention relates to a kind of O type circle erecting tools, this erecting tools is particularly suitable for the installation of internal diameter greater than 20 millimeters O type circles.
Background technology
During the engineering goods assembling, in order to seal the assembling that frequent needs carry out O type circle.The installation of O type circle class has two kinds of methods usually: a kind of craft is directly installed, add grease lubrication after, directly be pushed into the installation site with hand; Another kind is exactly to make light instrument, and the simple tool of using tweezers and so on places its spreading then.And the face internal diameter can't directly be packed into when assembling by hand greater than 20 millimeters big specification O type circle, and uses simple tool easily O type circle to be caused damage.
Summary of the invention
Technical problem to be solved by this invention provides a kind of O type circle erecting tools of can accurate assembling O type circle and can single manual complete operation.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of O type circle erecting tools, pawl removably to be connected by conical sleeve and elasticity and combine, the outer surface of conical sleeve is tapered, the thin butt end of holding of taper seamlessly transits, the number of degrees of conical sleeve cone angle alpha are 8 degree-12 degree, the butt end of conical sleeve is connected with installation shaft, the thin end of conical sleeve and the circular hole that elasticity is pawled form and removably connect, the diameter of the circular hole that elasticity is pawled and conical sleeve diameter at smaller end directly adapt, the opening of some five equilibriums on pawling, elasticity evenly is set, A/F A is the 1-1.5 millimeter, root at opening is provided with waist-shaped hole, the diameter of phi of the semicircle on waist-shaped hole both sides is the 6-10 millimeter, and the length L of corresponding waist-shaped hole is the 21-25 millimeter.
The opening of 8 five equilibriums evenly is set on described elasticity is pawled, and A/F A is 1.5 millimeters, is 8 millimeters in the diameter of phi of the semicircle on the waist-shaped hole both sides of the root setting of opening, and the length L of corresponding waist-shaped hole is 23 millimeters.
The butt diameter of described conical sleeve is the wall thickness that the diameter of installation shaft adds conical sleeve, and the wall thickness of conical sleeve is chosen the 0.3-0.5 millimeter, and the diameter at smaller end of conical sleeve directly is slightly less than O type circle internal diameter.
The number of degrees of described conical sleeve cone angle alpha are 10 degree.
Described elasticity is pawled and is adopted round steel 65Mn GB/T1222-1984 to make.
The wall thickness of described conical sleeve is chosen 0.3 millimeter.
The invention has the beneficial effects as follows: kit compact conformation, various gaps are chosen appropriately, adopt very little thrust can finish the installation of bigger O type circle, and the O type circle of big specification is accurate to be installed but the one man operation has well satisfied.Its dependable performance, easy to use, to O type circle not damaged.

Specific embodiment
When installation specification is the O type circle of 84 millimeters of internal diameters, 6.5 millimeters of width, adopt following erecting tools to install, as shown in Figure 1, a kind of O type circle 4 erecting tools, being pawled by conical sleeve 1 and elasticity 2 removably is connected and combines, and as shown in Figure 2, the outer surface of conical sleeve 1 is tapered.The butt end 11 of taper seamlessly transits to thin end 12, and the number of degrees of the cone angle alpha of conical sleeve 1 are 10 degree.The butt end 11 of conical sleeve is connected with installation shaft 3.Pawl 2 circular hole of the thin end 12 of conical sleeve and elasticity forms and removably connects.Butt end 11 diameters of conical sleeve are the wall thickness that the diameter of installation shaft 3 adds conical sleeve 1.The wall thickness of conical sleeve 1 is chosen 0.3 millimeter.Diameter and conical sleeve diameter at smaller end that thin end 12 diameters of conical sleeve are slightly less than the circular hole that O type circle 4 internal diameter elasticity pawl directly adapt.
As shown in Figure 3 and Figure 4, elasticity is pawled and 2 is adopted round steel 65Mn GB/T1222-1984 to make, and elasticity is pawled the opening 21 of eight equal parts evenly is set on 2.Opening 21 width A are 1.5 millimeters.Root at opening 21 is provided with waist-shaped hole 22.The diameter of phi of the semicircle on waist-shaped hole 22 both sides is 8 millimeters.The length L of corresponding waist-shaped hole 22 is 23 millimeters.
As shown in Figure 5, the whole erection process of O type circle is gone through inactive state to progressively spreading is to maximum rating, and moment falls after rise then, finishes installation process.In this process, elder generation on the thin end of conical sleeve, pawls O type snare with the cone of O type circle along guide sleeve with elasticity then, evenly promotes O type circle and slides in the groove of installation shaft.
It should be noted last that, above specific embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
