The purpose of this utility model is to overcome above-mentioned weak point of the prior art and proposes a kind of dual-purpose circlip mounting or dismounting that unite two into one with clamping.It can be applicable to easily that the hole is used and the mounting or dismounting of circlip for shaft, and easy to carry, has also saved material.
The utility model is finished as follows: the support zone of one of them caliper circular shaft shape support member that is fixedly connected, when the cramping body termination of two calipers lays respectively at left and right sides relative position, be shaped on two greater than circular shaft support member diameter and the hole concentric with it at another caliper support zone.During use, two supports on the circular shaft support member that is fixedly connected on one caliper and another caliper support zone are assembled respectively with the hole, so just formed two not Support Positions of same-action, changed the left and right sides relative position of cramping body termination simultaneously, reached a pair of tongs and be applicable to that the hole is used and the dual-purpose purpose of circlip for shaft mounting or dismounting.The utility model is easy to use, the exemplary construction that employing is described in detail below, and number of parts and cost almost do not increase.
Below with reference to accompanying drawing the utility model is described in further detail:
Fig. 1 is a kind of concrete structure figure of the present utility model.
Fig. 2 is the profile of Fig. 1 the utility model along A-A.
Whole members with reference to Fig. 1, Fig. 2, pliers adopt the metal material with certain mechanical strength to make.Caliper (1), (2) are divided into three parts: cramping body, support zone, handle.The cramping body of caliper (1), (2) is a bullet, and cone angle is major part with equaling a angle near support zone one end, and the outer end is the microcephaly, and the microcephaly is shaped on a little garden cylindricality, is used for the clamping circlip.The relative bullet of microcephaly's cylinder can be straight, also can be to spending perpendicular to page crooked 90.The support zone of caliper (1) is made a circular hole, and the hole is centered close on the extended line of center line of cone-shaped cramping body, is of a size of B apart from the termination, and hole outward flange thickness is not less than 4 millimeters.The support zone of caliper (2) is made two sizes greater than the hole of supporting cylinder shaft body (3) diameter, and hole and cooperating of circular shaft support member (3) can be relatively rotated.Two holes are positioned at caliper (2) taper cramping body center line symmetry both sides, and the angle of the line by the center, hole and the center line of taper cramping body equals cone angle a angle.The vertical dimension of two pitch-row cramping body terminations is B.Hole outward flange thickness is equal to caliper (1) and goes up hole outward flange thickness.Contact-making surface one side of caliper (1), (2) support zone is removed 1/2nd of caliper gauge, in order to the cramping body termination small cylinder central motion track of guaranteeing caliper (1), (2) on same camber line.Support member (3) is made cylinder shaft body, and the hole on its end and the caliper (1) is an interference fit.Support member (3) and caliper (1) also can directly be cast or forge and be one.Cooperating of (2) two holes of its other end and caliper for movingly, the end of stretching out caliper (2) supported hole is shaped on a radial dimension greater than aperture size, width dimensions is 1/2nd of aperture, is symmetrical in the symmetrical protruding flat of circular shaft support member (3) axle center.Simultaneously, on caliper (2) two supported holes corresponding to the protruding flat place of symmetry, open a size separately again greater than protruding flat, be symmetrical in the symmetrical groove of aperture center, so that protruding flat can passing through smoothly, the direct through groove that to open a width dimensions between caliper (2) support zone two holes be aperture size 1/2nd.The width center of symmetry groove and direct through groove all overlaps with the on line at center, two holes.Play the guiding role and the cross section of the part (4) of position-limiting action is square, the length of side is less than straight-through groove width.Part (4) top has a width dimensions protruding flat greater than aperture size greater than direct through groove width between caliper (2) two holes, length dimension, and the bottom is movably hinged with little pin (5) and circular shaft support member (3).Caliper (1), when (2) support zone contact-making surface is drawn close mutually, caliper (2) supported hole outer face is the gauge of caliper apart from the distance of the protruding flat nearest one side of part (4).When this spline structure can guarantee that support circular shaft spare (3) replaces between last two holes of caliper (2), the protruding flat direct through groove that can not pass through between two holes in part (4) top, make two calipers support contact-making surface and can separate a caliper thickness distance, but not exclusively break away from, and make caliper (2) direct through groove slide to another hole along part (4) by a hole reliably.The handle of caliper (1), (2) is made the cross section and is oval arc handle, can be made into reticulate pattern flower shape with the staff contact site, to increase roughness and aesthetic feeling.Alphabetical size among Fig. 1, Fig. 2 and alphabetical dimension scale relation are as follows:
