Abstract
The utility model discloses a hand-operated piston clamp spring installing tool which comprises a mandrel and an outer guiding sleeve arranged on the periphery of the mandrel. A push end cover is arranged at one end of the mandrel. A spring is arranged between the push end cover and the outer guiding sleeve. An opened claw is arranged at the other end of the mandrel. A guiding sleeve is arranged on the periphery of the opened claw. The diameter of an inner hole of the guiding sleeve becomes gradually smaller towards an exit. As the opened claw is arranged on the mandrel, the inner diameter of the guiding sleeve becomes gradually smaller from the opened claw to the exit; an opening is formed in the place where the diameter of the inner hole is the largest of the guiding sleeve and used for containing a clamp spring. The end, adjacent to the opened claw, of the mandrel is hollow so as to facilitate deformation of the opened claw. The hand-operated piston clamp spring installing tool is simple in structure, and capable of achieving the objective that a piston pin clamp spring of an engine can be automatically assembled so as to improve speed and safety in assembling the clamp spring and suitable for assembling an engine.
Description
Technical field
The utility model belongs to the manual piston jump ring frock in engine mounting technology field, particularly a kind of engine, is applied to the engine assembling activity.
Background technology
The piston pin clamping spring of engine is shaped as the annulus of gap, and rigidity is very big, and is slightly larger than the piston hole of required assembling, and is very inconvenient in the piston pin clamping spring assembling process of engine, jump ring often takes place collapse the situation that to cause the workman injured.
No matter in the assembling of new product, or the maintenance dismounting of product, traditional assembly method is difficult to satisfy high efficiency and security requirement.
China invention CN 102407440 A disclose a kind of engine gudgeon pin jump ring assemble mechanism, engine gudgeon pin jump ring assemble mechanism comprises press-loading apparatus, the jump ring pressure head, the guide pillar that press-fits of press-loading apparatus is rod-like structure, press-fiting guide pillar one end press-fits the flexible flexible rod member of guide pillar with control and is connected, the jump ring pressure head is set to the tubular structure of hollow, the centre is ram cavity, jump ring pressure head upper end arranges fluting, flexible rod member is set to pass the structure of jump ring pressure head, jump ring pressure head front end is provided for the fixed mount of the piston of fixing jump ring to be installed, when piston was fixed on the fixed mount, piston pin hole was set to and press-fits guide pillar and be in structure on the same straight line, press-fited guide pillar when stretching out forward, can extend in the piston pin hole, press-loading apparatus is connected with the controller of control press-loading apparatus work.Though jump ring collapsed the risk that to hurt sb.'s feelings easily when this invention can be avoided hand assembled, play protection assembly crewman's effect.But its complex structure causes cost of manufacture very high, and operational sequence is also a lot, the operating efficiency of influence production or service worker.
Summary of the invention
The utility model is in order to overcome the shortcoming that above prior art exists, its technical scheme that provides provides a kind of simple in structure, can realize the assembly automation of engine gudgeon pin jump ring, thereby improve the engine gudgeon pin jump ring assemble mechanism of jump ring assembling speed and assembling safety.
For this reason, the utility model provides a kind of manual dress piston jump ring frock, the outer bush that comprises mandrel and mandrel outside, one end of mandrel is provided with the hand push end cap, be provided with spring between hand push end cap and the outer bush, the other end of mandrel is provided with the opening pawl, and opening pawl outside is provided with guide pin bushing, and the interior pore radius of guide pin bushing reduces gradually toward Way out.
As to the further specifying of manual dress piston jump ring frock described in the utility model, guide pin bushing is provided with an opening at interior pore radius maximum.
As to the further specifying of manual dress piston jump ring frock described in the utility model, be provided with packing ring between spring and the hand push end cap.
As to the further specifying of manual dress piston jump ring frock described in the utility model, nearly opening pawl one end of mandrel is provided with hollow cavity.
As to the further specifying of manual dress piston jump ring frock described in the utility model, the periphery in guide pin bushing exit is provided with level and smooth inclined-plane.
The beneficial effects of the utility model are: because the utility model mandrel is provided with the opening pawl, the opening pawl is toward the direction of outlet, the internal diameter of guide pin bushing reduces gradually, guide pin bushing is provided with an opening at interior pore radius maximum, being used for jump ring puts into, nearly opening pawl one end of mandrel is hollow, is conducive to the distortion of opening pawl.The utility model structure is simple in structure, can realize the assembly automation of engine gudgeon pin jump ring, thereby improves jump ring assembling speed and assembling safety, is applicable to the assembling of engine.
Description of drawings
Fig. 1 is the cutaway view of manual dress piston jump ring frock described in the utility model;
Fig. 2 is the structural representation of jump ring described in the utility model;
Among the figure: 1-guide pin bushing, 11-opening, 12-outlet, 13-inclined-plane, 2-mandrel, 21-opening pawl, 22-cavity, 3-outer bush, 4-spring, 5-packing ring, 6-hand push end cap, 7-piston, 71-jump ring, 72-jump ring groove.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Only indicate the main position relevant with the utility model among the figure, as shown in Figure 1, the utility model provides a kind of manual dress piston jump ring frock, the outer bush 3 that comprises mandrel 2 and mandrel 2 outsides, one end of mandrel 2 is provided with hand push end cap 6, be provided with spring 4 between hand push end cap 6 and the outer bush 3, be provided with packing ring 5 between spring 4 and the hand push end cap 6.The other end of mandrel 2 is provided with opening pawl 21, mandrel 2 nearly opening pawl 21 1 ends are hollow cavity 22, be conducive to 21 distortion of opening pawl, opening pawl 21 outsides are provided with guide pin bushing 1, the interior ring of guide pin bushing 1 is less than opening pawl 21, make opening pawl 21 be in deformation state, the interior pore radius of guide pin bushing 1 reduces gradually toward outlet 12 directions always.Guide pin bushing 1 is provided with an opening 11 at interior pore radius maximum, is used for putting into of jump ring 71.The periphery at guide pin bushing 1 outlet 12 places is provided with level and smooth inclined-plane 13, make guide pin bushing 1 external diameter less than the jump ring groove 72 of piston 7 main bodys, be conducive to and the docking of piston 7 main bodys, when jump ring 71 comes out in guide pin bushing 1 endoporus, can enter jump ring groove 72 the insides of piston 7 main bodys smoothly.
As shown in Figure 2, piston 7 pin jump rings 71 are shaped as the annulus of gap, and rigidity is very big, and is slightly larger than the jump ring groove 72 of required assembling.
