Abstract
The invention provides a surface treatment method for a casted and formed eccentric shaft. The surface treatment method comprises the steps that firstly, the eccentric shaft is preliminarily polished; secondly, the interior and the exterior of the eccentric shaft are added with different mediums to be subjected to ball milling; and finally, the eccentric shaft is accurately polished on a polishing machine. The surface treatment method for the casted and formed eccentric shaft is a unique surface treatment method which is designed on the basis of the characteristics of the eccentric shaft; different ball milling processes are conducted on the interior and the exterior of the eccentric shaft; and the service life of the eccentric shaft can be substantially prolonged.
Description
Technical field
The present invention relates to engineering machinery field, specifically a kind of shock resistance type eccentric shaft casting technique.
Background technology
Eccentric shaft is the same with its name, its center not at the center of axis, general axle, can only drive workpiece rotation, but eccentric shaft, not only can transmit rotation, revolution can also be transmitted simultaneously.Eccentric shaft is fixing with on electric machine rotational axis generally by eccentric orfice, when electric motor starting, does cam motion.Therefore automobile, electromotor, pump etc. it are widely used in.
Eccentric shaft also needs to transmission revolution due to not only rotation, and when it rotates, external and internal compositions stress is uneven.Existing process for treating surface uses identical processing method to the surfaces externally and internally of eccentric shaft, and often when outer surface meets mechanical requirements, scarce being damaged of inner surface causes whole eccentric shaft to lose efficacy.
Summary of the invention
The present invention is to solve problem of the prior art, devise the surface treatment method of uniqueness according to the feature of eccentric shaft, for the ball-milling technology that the inside and outside employing of eccentric shaft is different, it is possible to significantly extend the service life of eccentric shaft.
One casting eccentric shaft surface treatment method of the present invention, comprises the following steps:
1) use 5 mesh, 20 mesh, the sand paper of 100 mesh that the eccentric shaft cast(ing) surface after the demoulding is tentatively polished successively；
2) putting in ball mill by eccentric shaft, add soft steel ball, and seal axis hole in eccentric shaft axle center, add hardened steel ball, carry out ball milling in ball mill, rotating speed is 300 r/min～400 r/min, ball milling 5～8h, opens axis hole and take out soft steel ball after ball milling；
3) eccentric shaft after ball milling is put on buffing machine, select the medium of 1000 mesh and 2000 mesh to be polished respectively, complete surface and process.
Step 2) described in hardened steel ball, quality is 500 g～600 g, and ball-milling medium radius is Ф 4mm～Ф 10mm.
Step 2) described in soft steel ball, quality is 100 g～200 g, and ball-milling medium radius is Ф 1mm～Ф 3mm.
The present invention has the beneficial effects that: devise the surface treatment method of uniqueness according to the feature of eccentric shaft, for the ball-milling technology that the inside and outside employing of eccentric shaft is different, it is possible to significantly extend the service life of eccentric shaft.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be further described.
The present invention comprises the following steps:
1) use 5 mesh, 20 mesh, the sand paper of 100 mesh that the eccentric shaft cast(ing) surface after the demoulding is tentatively polished successively；
2) putting in ball mill by eccentric shaft, add soft steel ball, and seal axis hole in eccentric shaft axle center, add hardened steel ball, carry out ball milling in ball mill, rotating speed is 300 r/min～400 r/min, ball milling 5～8h, opens axis hole and take out soft steel ball after ball milling；
3) eccentric shaft after ball milling is put on buffing machine, select the medium of 1000 mesh and 2000 mesh to be polished respectively, complete surface and process.
Step 2) described in hardened steel ball, quality is 500 g～600 g, and ball-milling medium radius is Ф 4mm～Ф 10mm.
Step 2) described in soft steel ball, quality is 100 g～200 g, and ball-milling medium radius is Ф 1mm～Ф 3mm.
The present invention has the beneficial effects that: devise the surface treatment method of uniqueness according to the feature of eccentric shaft, for the ball-milling technology that the inside and outside employing of eccentric shaft is different, it is possible to significantly extend the service life of eccentric shaft.
The concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, it should be pointed out that; for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvement, these improvement also should be regarded as protection scope of the present invention.
