Abstract
The utility model relates to a pair of dismounting pliers for a clamp ring of a mechanical shaft. The internal lateral sides of two half pliers-openings are made as arc surfaces, two arc surfaces are smooth, the shaft cores of the two arc surfaces opposite and are the same. The two bottom end surfaces of the pliers-openings are respectively made as convex blade and an arc step. The depth of the arc step is larger than the radius of the spring wires of the clamp ring, and the shaft cores of the step and the arc surface are the same. The dismounting pliers can conveniently and quickly mount or dismount the spring wires and the clamp rings on the mechanical shaft.
Description
Technical field
The utility model relates to the dismounting of the spring wire snap ring on automobile starter and other mechanical mechanical axis, is a kind of instrument.
Background technology
At present, during maintenance starter motor or other machinery, the dismounting of the spring wire snap ring on the mechanical axis all is with the semi-hand mode, operating difficulties and be prone to hurt finger.
Summary of the invention
The utility model provides a kind of dismounting pincers that are exclusively used in snap ring on the mechanical axis for overcoming the above problems.
The technical scheme that the utility model adopts is: curved of the medial surface of two halves jaw; Two cambered surfaces are smooth, concentric and relative, and two bottoms of jaw are respectively the sword and the arc step of protrusion; The degree of depth of arc step is greater than the radius of the spring wire of snap ring, they and above-mentioned arcwall face concentric.
The beneficial effect of the utility model is: when snap ring is installed; Arcwall face with arc step place picks up snap ring gently; Lie on the axial end, rap jaw, snap ring is enclosed within on the axle with hammer; Then can be without lifting an eyebrow in the snap ring shift-in annular groove, therefore use this specific purpose tool dismounting spring wire snap ring convenient and swift.
Description of drawings
Fig. 1 is the external view of the utility model.
Fig. 2 is the external view of mechanical axis and spring wire snap ring.
Description of reference numerals:
1 sword; 2 arc steps; 3 mechanical axis; 4 annular grooves; 5 axial end; 6 snap rings.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is further specified.
As shown in the figure, when tearing snap ring 6 open, extrude annular groove 4 to an end of snap ring 6 openings with the sword 1 of dismounting pincers; Along snap ring 6 rotary machine axles 3, snap ring 6 is extruded annular groove 4 successively, when an end that is extruded will bounce back into annular groove 4 again; Second half jaw that is turned over is blocked, and can not return in the annular groove 4, is rotated further mechanical axis 3; Just can extrude annular groove 4 to snap ring 6 fully, can take off snap ring 6 from axle 3 easily then.
When snap ring 6 is installed, pick up snap ring 6 gently, lie on the axial end 5, rap jaw, snap ring 6 is enclosed within on spools 3 with hammer with the arcwall face at arc step 2 places, then can be without lifting an eyebrow in the snap ring 6 shift-in annular grooves 4.
