Abstract
The utility model relates to an abrading device for the valve seat of an internal-combustion engine, which comprises a piece of centering shaft, a rocking handle, a conic abrading wheel, a thrust bearing, a pressure spring and a regulating nut. The upper end of the centering shaft forms the rectangle, and the centering shaft can be inserted into a square hole which is arranged on the end part of the rocking handle. The upper part of the inner hole of the conic abrading wheel is big, and the lower part is small, so the inner hole is tightly matched with the conic part of the centering shaft. The thrust bearing is arranged on the lower part of a processing part. The pressure spring and the regulating nut are orderly arranged on the centering shaft which is arranged on the lower part of the bearing. Being used for abrading valve seats, the utility model has the advantages of labor saving, time saving and the improvement of smoothness.
Description
The utility model relates to a kind of being used for engine valve is carried out abradant sand milling device, and it is used in the processing and the repair of valve seating especially.
When the valve seating of internal combustion engine was repaired, the mode that generally adopts reamer and grinding to combine divided two procedures to carry out, and this method is time-consuming, and the fineness of product is not high yet.
The utility model is designed a kind of sand milling device at existing problem in the above-mentioned prior art, it is particularly suitable for engine valve seat is ground and repaired, it not only can save operation, with two procedures and be together, and can improve the fineness of product.
Sand milling device of the present utility model comprises a centration axis, a rocking handle, a tapered wheel, a thrust bearing, a compression spring and an adjusting nut, the upper end cross section of centration axis is rectangular, it can insert in the square hole of rocking handle end, and the endoporus of tapered wheel is up big and down small, with the taper position tight fit of centration axis, thrust bearing is contained in the below of processing component, on the centration axis of bearing below compression spring and adjusting nut is housed successively.
Adopt above-mentioned sand milling device, can the valve seating of internal combustion engine effectively be ground, replace reamer, not only reduced the cost of process tool, and saved process time, improved machining accuracy, avoided the generation of tool marks with it.To a valve reseating job, only needed to finish in 3～5 minutes usually, the wear extent of emery wheel is also seldom.
Accompanying drawing 1 is the generalized section of a preferred embodiment of the utility model sand milling device.
Below in conjunction with this accompanying drawing the utility model is described in further detail.
Shown in the label 4 in the accompanying drawing is a centration axis, its top removable mounting one rocking handle 7, the tapered portion tight fit of tapered wheel 5 and centration axis.For the ease of the dismounting of tapered wheel, a dismounting nut 6 can be equipped with in its top, rotates this nut 6 and just emery wheel can be backed off.Can insert below the tapered portion of centration axis in the valve guide bushing, the two preferably is and is slidingly matched, so that strengthen its positioning action.Thrust bearing 3 is contained in the lower end of centration axis, and compression spring 2 and nut 1 are equipped with in its below, and this nut 1 is a wing nut preferably, and it is screwed onto in the screw thread of centration axis lower end, rotates this nut, can adjust the pressure between tapered wheel and the valve seating.
Above embodiment only is used for the utility model is described, and does not constitute restriction of the present utility model.As those skilled in the art; be easy to the foregoing description is improved; for example; can replace rocking handle that centration axis is driven with electronic mode; the size of tapered wheel and centration axis can change to some extent according to the valve seating of being processed, and these changes all should be considered as within protection domain of the present utility model.
