Abstract
The utility model provides a riveting device for an oil seal on a front end cover of a starting engine, belonging to the technical field of riveting. The riveting device comprises a guide post and a rivet stem with a center hole, wherein the rivet stem and the guide post have the common central axis X; the rivet stem is provided with an outer cylindrical rivet stem surface with a diameter L1; the rivet stem is provided with an inner cylindrical rivet stem surface with a diameter L2; the guide post is provided with an outer cylindrical guide post surface with a diameter L3; the bottom of the rivet stem is provided with a riveting point coupled with a riveting point arranged on the oil seal on the front end cover of the starting engine; and L1 is larger than L2, and L2 is equal to L3. After the scheme provided by the utility model is adopted, the front end cover can be effectively sealed on a front end cover opening of the starting engine, good fixing effect and high stability are achieved, no influence is caused to the fixation of the front end cover even if the starting engine is in an adverse working environment, the processing steps are reduced, and the assembling efficiency is increased.
Description
Technical field
The utility model relates to a kind of device that presses, especially a kind of starting machine front end cover oil sealing device that presses.
Background technology
In the prior art, during the work of starter starter, electromagnetic switch energising pulling shift fork starter energising rotation, the isolator of shift fork driven rotary outwards moves, and the bull gear engagement in engine drives engine ignition work.The high speed rotation makes isolator break away from gear ring after the engine work, accomplishes one action, so isolator of the every work of starter will pass in and out once; In such course of work; Extraneous dust foreign material get into the drive end bearing bracket mouth easily, cause the starter job failure, reduce the life-span.
Traditional way is that the drive end bearing bracket mouth at starter installs a drive end bearing bracket additional; On drive end bearing bracket and the drive end bearing bracket mouth screw thread that intercouples is arranged; Drive end bearing bracket is fixed together with the drive end bearing bracket mouth through rotation, and starter can produce vibrations in the course of the work, and the vibrations of generation make the fixedly absent-mindedness of drive end bearing bracket and drive end bearing bracket mouth; Such mounting means is unreliable, after starter works long hours, comes off easily.
The utility model content
The purpose of the utility model provides a kind of starting machine front end cover has blast riveting device, comprises rivet rod and guide pillar with centre bore, and die and guide pillar have common central axis X,
Said rivet rod has the cylindrical rivet rod outer surface that diameter is L1;
Said rivet rod has the cylindrical rivet rod inner surface that diameter is L2;
Said guide pillar has the direct cylindrical guide pillar outer surface of L3 that is;
The riveting point that is provided with on bottom setting of said rivet rod and the starting machine front end cover mouth is pressing a little of coupling mutually; Wherein L1 is greater than L2, and L2 equals L3.
Rivet rod is provided with centre bore, is to connect the apparatus that presses when pressing.
Rivet rod and guide pillar all are cylindrical, and guide pillar can effectively guide the position of rivet rod when carrying out riveting work, makes that the position of riveting is just right.
Before carrying out the riveting action, several riveting points are set on the starting machine front end cover mouth, what the riveting point on setting of rivet rod bottom and the starting machine front end cover mouth was coupled presses a little, is convenient to when pressing stable regularly.
As preferably, the said quantity that presses a little is even number.The feasible action that presses is even to having an effect of starting machine front end cover, and fixed effect is better.
As preferably, said pressing a little evenly distributes in the rivet rod bottom.Press a little to be evenly distributed with and be beneficial to fixing more reliable of starting machine front end cover in the rivet rod bottom.
As preferably, the said quantity that presses a little is six.The number of spots that presses of rivet rod bottom is six, helps processing and good fixing effect.
As preferably, said rivet rod outer surface and said rivet rod inner surface are a little crossing through pressing in the rivet rod bottom.Press a little is to be crossed by the outer surface of rivet rod and inner surface bending to form.
After the scheme that employing the utility model provides; Can seal up drive end bearing bracket at the starting machine front end cover mouth effectively, good fixing effect, stability are high, even be in the bad working environment also not can fixedly exerting an influence to drive end bearing bracket for starter; Reduce procedure of processing, increase efficiency of assembling.

Embodiment
The starting machine front end cover oil sealing that the utility model the provides device that presses comprises rivet rod and the guide pillar with centre bore, and die and guide pillar have common central axis X, and said rivet rod has the cylindrical rivet rod outer surface that diameter is L1;
Said rivet rod has the cylindrical rivet rod inner surface that diameter is L2; Said guide pillar has the direct cylindrical guide pillar outer surface of L3 that is; The riveting point that is provided with on bottom setting of said rivet rod and the starting machine front end cover mouth is pressing a little of coupling mutually; Wherein L1 is greater than L2, and L2 equals L3.
Rivet rod is provided with centre bore, is to connect the apparatus that presses when pressing.
Rivet rod and guide pillar all are cylindrical, and guide pillar can effectively guide the position of rivet rod when carrying out riveting work, makes that the position of riveting is just right.
Before carrying out the riveting action, several riveting points are set on the starting machine front end cover mouth, what the riveting point on setting of rivet rod bottom and the starting machine front end cover mouth was coupled presses a little, is convenient to when pressing stable regularly.
The said quantity that presses a little is even number.The feasible action that presses is even to having an effect of starting machine front end cover, and fixed effect is better.
Said pressing a little evenly distributes in the rivet rod bottom.Press a little to be evenly distributed with and be beneficial to fixing more reliable of starting machine front end cover in the rivet rod bottom.
The said quantity that presses a little is six.The number of spots that presses of rivet rod bottom is six, helps processing and good fixing effect.
Said rivet rod outer surface and said rivet rod inner surface a little intersect through pressing in the rivet rod bottom.Press a little is to be crossed by the outer surface of rivet rod and inner surface bending to form.
