Abstract
The invention relates to a pair of shaft check ring calipers. The pair of shaft check ring calipers comprises a limiting ring, two cover plates, cylindrical pins, two caliper bodies, two connecting rods and a limiting pin. The two cover plates are fixed through screws. The two caliper bodies are symmetrically installed between the cover plates through the cylindrical pins. One end of each connecting rod is hinged to the corresponding caliper body, and the other ends of the connecting rods are connected together through the limiting pin. The two ends of the limiting pin are located inside grooves formed in the two cover plates correspondingly. The limiting ring is installed on the cover plates. A step is arranged on the limiting ring. The diameter of the step is identical with the diameter of a shaft check ring, expanded to the ultimate state, to be installed. The pair of shaft check ring calipers effectively solves the problem that when a pair of common shaft check ring calipers is used, a check ring is prone to disengagement; and meanwhile, the deformation of the check ring is effectively limited, and the quality problem that because of an excessively large force, the check ring generates permanent deformation in the operation process is prevented.
Description
Technical field
It is especially a kind of to require that the limitation anti-Sealing shield ring of back-up ring deflection is produced forever the present invention relates to a kind of shaft block ring clamp
The back-up ring clamp for deforming long.
Background technology
Shaft block ring can prevent axle from axial motion occurring after installing.A kind of structure therein is strutted by back-up ring clamp
Back-up ring opening makes back-up ring produce elastic deformation, then shield ring sleeve at the annular groove of shaft end, unclamps back-up ring clamp, and back-up ring recovers deformation
It is stuck at axle annular groove.General shaft block ring clamp are simply to strut back-up ring with jaw, and back-up ring is easily separated from, and falls into dress
Potential danger is formed with machine, general shaft block ring clamp do not limit the deflection of back-up ring yet, due to firmly excessive in operation
Easily there are the quality problems of back-up ring permanent deformation, cause whole machine operating to produce loud noise.
The content of the invention
It is an object of the invention to provide a kind of shaft block ring clamp, can not fallen off with the firm back-up ring that struts, and control back-up ring
Deflection, anti-Sealing shield ring produces permanent deformation, it is ensured that the reliability after assembling.
Concrete technical scheme of the invention is：Described shaft block ring clamp include circle band, cover plate, straight pin, caliper,
Connecting rod, spacer pin, plug, compression spring, embolism, cover plate are two pieces, are fixed by screw, and caliper is two, respectively by circle
Pin is symmetrically mounted between cover plate, and one end of caliper is handle, and the other end is jaw, can be blocked at the opening of shaft block ring；
Connecting rod is two, and one end is hinged with two calipers respectively, and the other end is linked together by spacer pin, the two of described spacer pin
End is located in the groove set on two cover plates respectively, and described groove is located at two symmetrical line positions of caliper, and spacer pin exists
Can be moved in groove under the drive of caliper；Described circle band is installed on the cover board, and positioned at the vice jaw part of caliper, circle band
On be provided with step, described stepped diameters are identical with the diameter under shaft block ring swell to limiting condition to be installed, limitation
It is additionally provided with circle perpendicular to two side openings of the line of symmetry of caliper, described hole is two, is symmetrical arranged, and is installed in each hole
There is compression spring, described spring one end is pressed on the plug for being arranged on aperture, and the other end is pressed in the jaw of caliper by embolism
Outside.
Operationally, first be put into back-up ring in the groove of pliers circle band by the present invention, and back-up ring opening falling to closed in caliper upper end
At the jaw of conjunction, holding conjunction caliper handle makes jaw strut back-up ring, while limiting the extreme position that loop diameter limits back-up ring, prevents
Back-up ring deformation is excessive, while be also prevented from back-up ring departing from from jaw.Circle band size of the invention is given according to specific back-up ring size,
Permanent deformation is produced for limiting the anti-Sealing shield ring of back-up ring deflection, handle realizes the opening and closing movement of jaw, and straight pin is in connecting rod
In groove linear movement under drive, it is ensured that the symmetry of jaw opening and closing movement.Embolism, spring and plug are arranged on circle band
Side opening in, jaw is maintained at the nature of closure.Used present invention efficiently solves general shaft block ring clamp
Guide ring is easily separated from problem, while the deflection of back-up ring is also effectively limit, due to excessive initiation of exerting oneself in preventing from operating
Back-up ring permanent deformation quality problems.

Specific embodiment
As illustrated, shaft block ring clamp include circle band 1, cover plate 2, straight pin 3, caliper 5, connecting rod 6, spacer pin 7, stifled
First 8, compression spring 9, embolism 10, cover plate 2 are two pieces, are fixed by screw, and caliper 5 is two, symmetrical by straight pin 3 respectively
Between cover plate 2, one end of caliper 5 is handle, and the other end is jaw, can be blocked at the opening of shaft block ring；Connecting rod 6 is
Two, one end is hinged with two calipers 5 respectively, and the other end is linked together by spacer pin 7, the two ends of described spacer pin 7
It is located in the groove set on two cover plates 2 respectively, described groove is located at two symmetrical line positions of caliper 5, spacer pin 7 exists
Can be moved in groove under the drive of caliper 5；Described circle band 1 is arranged on cover plate 2, and positioned at the vice jaw part of caliper 5, limit
Step is provided with system circle 1, described stepped diameters are identical with the diameter under shaft block ring swell to limiting condition to be installed,
It is additionally provided with circle band 1 perpendicular to two side openings of the line of symmetry of caliper 5, described hole is two, is symmetrical arranged, each hole
Compression spring 9 is inside installed, described one end of spring 9 is pressed on the plug 8 for being arranged on aperture, and the other end is pressed in by embolism 10
The jaw outside of caliper 5.
