Abstract
The utility model discloses a fixture for preventing a snap ring from dropping. The fixture comprises a cone guide pillar and a guide sleeve, wherein the center of the guide sleeve is provided with a hole and is connected with the guide pillar in a matching manner, a limiting part for fixing the location of the snap ring is arranged on the guide pillar, an annular beading for being held is arranged on one end of the guide sleeve, the hole penetrates through the beading end of the guide sleeve to form a blind hole, the limiting part is an annular groove, and the diameter of the bottom of the groove is less than the inner diameter of the snap ring. The fixture has the beneficial effects that the limiting part for fixing the location of the snap ring is arranged on the guide pillar, components are difficult to drop during connection, thus a better connecting effect is achieved, the working efficiency is indirectly increased, and strong practical applicability is obtained.
Description
Technical field
The utility model relates to a kind of anti-snap ring tool that comes off.
Background technique
Snap ring need cooperate the back application of force that it is embedded through guide pillars and bushes when being connected with the screw draw-in groove.Existing guide pillar is taper, offers the through hole that matches with guide pillar on the guide pin bushing.But snap ring is set on the smooth guide pillar, do not have spacing, unbalance stress, the snap ring easy deformation, and since guide pin bushing on through hole, be prone to cause snap ring extrusion-deformation.
Summary of the invention
The purpose of the utility model is to solve above-mentioned technical problem, proposes a kind of anti-snap ring tool that comes off.
The purpose of the utility model will be achieved through following technological scheme:
A kind of anti-snap ring tool that comes off; Comprise that taper guide pillar and center offer guide pin bushing porose and that be connected with guide pillar, said guide pillar be provided with one be used for fixing the snap ring position limited part, an end of said guide pin bushing is provided with and is used to pinch the annular convex shoulder of holding; The convex shoulder end that guide pin bushing is passed in said hole forms a blind hole; The degree of depth of said blind hole equates that with the height of guide pillar said limited part is the groove of annular, and the bottom land place diameter of said groove is less than said snap ring internal diameter.
The beneficial effect of the utility model is mainly reflected in: guide pillar is provided with the limited part that is used for fixing snap ring, makes to make parts snap ring difficult drop-off when connecting to connect better effects if, has improved working efficiency, and is practical.

Fig. 1 is the guide pillar structural representation of the utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the guide pillar structural representation of the utility model.
Fig. 4 is the plan view of Fig. 3.
Embodiment
The utility model provides a kind of anti-snap ring tool that comes off, and to shown in Figure 4, comprises that taper guide pillar and center offer guide pin bushing porose and that be connected with guide pillar like Fig. 1.
Be difficult for when preventing that snap ring is set on the guide pillar causing unbalance stress to be out of shape because of reason such as rocking, said guide pillar be provided with one be used for fixing the snap ring position limited part, said limited part is annular groove 1.
One end of the guide pin bushing 21 supporting with it is provided with and is used to pinch the annular convex shoulder of holding 2; Convex shoulder 2 ends that guide pin bushing 21 is passed in said hole form a blind hole 22; Bottom land 11 place's diameters of said groove 1 are slightly less than said snap ring internal diameter, make snap ring just in time be set in groove and do not tilt.
During use, screw prevents in the U-shaped spring, guide pillar bottom 12 to be fixed in the screw hole; Snap ring is set on the guide pillar, fixes, then guide pin bushing 21 is set on the guide pillar through the groove 1 of guide pillar; The application of force on guide pin bushing; Because guide pin bushing is provided with blind hole 22, the degree of depth of blind hole 22 and the height of guide pillar about equally can be owing to through hole causes the stressed excessive snap ring distortion that makes.
The improvement of the utility model is practical, has improved work efficiency, makes the reject ratio of product thoroughly be resolved.
The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technological schemes of forming all drop within the protection domain of the utility model.
