Abstract
The invention relates to a two end-face centre hole position finding laying-out table of bent shaft and a centre hole positioning process. The invention relates to a device of a two end-face centre hole position finding laying-out table of bent shaft on heat treating time and a centre hole positioning process. The two end-face centre hole position finding laying-out table of bent shaft comprises an engine bed and two roller support saddles, wherein two roller brackets are mounted on the support saddle and a scriber is allocated on the two ends of the engine bed and a spring is behind the scriber and the scribers of two ends are in the same axial cord face to face. The bent shaft is mounted on the roller for positioning the roller brackets of the laying-out table and scriber pictures circle on the two ends of the bent shaft. The center of circle is the position of the centre hole for positioning. The bent shaft to be discarded as useless due to not machining enough is processed into accepted product by the said method.
Description
[technical field]
The present invention relates to a kind of device of the both ends of the surface centre bore line for long (distortion) the bigger bent axle (as six-cylinder crankshaft) of beating when the heat treatment and the method that the crankshaft end-face centre bore is located.
[background technology]
At present, the bent axle after the roughing is beated big when heat treatment, often scraps because of not enough processing.Particularly long bent axle (as six-cylinder crankshaft) loss is even more serious.
[summary of the invention]
The bent axle that some will be scrapped originally the purpose of this invention is to provide a kind of crankshaft two end face centre bore location marking-off table and centre bore localization method, so that by the both ends of the surface centre bore location to (distortion) the bigger bent axle of beating, can be processed into qualified products again.
The object of the present invention is achieved like this: crankshaft two end face centre bore location marking-off table comprises support, two roller supports are arranged on the support, the rolling wheel support of two rollers is housed on the roller support, there is the scriber support at the support two ends, scriber is contained on the scriber support, spring is equipped with in the scriber back, and the scriber at frame two ends is relative, and on same axis.
The localization method of crankshaft two end face centre bore is: bent axle is put on the roller of crankshaft two end face centre bore location marking-off table rolling wheel support, scriber is withstood on the end face of bent axle, 360 ° of turning crankshafts, promptly leave the big or small corresponding circular path with jerk value (deflection), the central hole location that promptly locate in the center of circle of this circumference this moment on the crankshaft two end face.
Advantage of the present invention is that the method by to its end face centre bore location makes it to be processed into qualified products for the long bigger bent axle that will scrap because of not enough processing of beating when the heat treatment.Thereby, reduce the loss, for enterprise brings tangible economic benefit.
[description of drawings]
Fig. 1 is the structural representation of crankshaft two end face centre bore of the present invention location marking-off table;
Fig. 2 is the A-A cutaway view of rolling wheel support.
[specific embodiment]
With reference to Fig. 1,2, crankshaft two end face centre bore location marking-off table comprises support 1, two roller supports 4 are arranged on the support, the rolling wheel support 3 of two rollers is housed on the roller support, there is scriber support 2 at the support two ends, and scriber 5 is contained on the scriber support, and spring is equipped with in the scriber back, the scriber at frame two ends is relative, and on same axis.
With reference to Fig. 1,2, the localization method of crankshaft two end face centre bore is: bent axle 6 is put on the roller of crankshaft two end face centre bore location marking-off table rolling wheel support, scriber is withstood on the end face of bent axle, 360 ° of turning crankshafts, promptly leave the big or small corresponding circular path with jerk value (deflection), the central hole location that promptly locate in the center of circle of this circumference this moment on the crankshaft two end face.
