Abstract
The invention relates to a method for turning counterbores at two ends. In order to solve the problem that coaxiality of counterbores at two ends can not be ensured, the method for turning the counterbores at two ends provided by the invention has the following steps: 1) turning a counterbore in one end surface of a processed part; 2) processing a circular tooling part in accordance with the diameter of the counterbore, processing a center bore in the circle center of the tooling part, and forming interference fit by matching the diameter of the tooling part with the diameter of the counterbore; and 3) assembling the processed tooling part and the processed counterbore as a whole in a manner of little interference, and turning the counterbore in the other end of the part by using a lathe center to hold the center bore of the tooling part. In the method for turning the counterbores at two ends provided by the invention, the self-made tooling part is adopted, the processing position of each counterbore is located by the center bore, and the counterbores at two ends of the processed part can be ensured to be on the same axis, thereby meeting the drawing requirements.
Description
Technical field
The present invention relates to the processing method of a kind of two ends band counterbore, especially the axiality of two ends counterbore requires to have more high-precision processing method.
Background technology
In actual production, to process the counterbore of the both ends of the surface of part shown in Figure 1, adding man-hour, need to guarantee the requirement of drawing regulation.Traditional processing technology is the line center-punching → brill aperture → reaming of blanking → plane → line center-punching → brill aperture → reaming → go to other end.The frequent axiality of counterbore of the part both ends of the surface after the method for this kind line brill counterbore causes processing can't guarantee.Reason mainly contains: 1, pincers worker setting-out, and during setting-out, there are the error of perpendicularity in line datum level and line face; 2, center-punching to workman's qualification dependence height, causes error big; 3, the sample dotting punch is too little, and is poor to the positioning and guiding of drill bit, and causes borehole throw big.More than the various accumulations of error get up, just can cause very big error to occur.
Summary of the invention
For the problem that the axiality that solves the both ends of the surface counterbore can't guarantee, the invention provides the method for turning of a kind of two ends band counterbore.
The technical solution adopted in the present invention is that the method for turning of a kind of two ends band counterbore is characterized in that: this method process the following step:
A, at an end face of institute's processing parts line centering, withstand centre bore with lathe centre, clamp with chuck simultaneously, car goes out counterbore in the other end of part;
B, process circular frock part according to counter bore hole diameters, in machining center hole, the center of circle of frock part, frock part diameter and counter bore hole diameters are joined work can form interference fit;
C, the frock part that processes and manufactured counterbore are assembled into one in the mode of interference slightly, withstand the centre bore of frock part, clamp part with chuck simultaneously, car part other end counterbore with lathe centre.
The method for turning of two ends provided by the present invention band counterbore adopts self-control frock part, processes each counterbore and locatees with centre bore, and the part both ends of the surface counterbore after the processing can be guaranteed to meet the drawing requirement on same axis.
Description of drawings
The present invention will be further described below in conjunction with accompanying drawing and example.
Fig. 1, part drawing
Fig. 2, Figure 1A-A are to cutaway view.
Fig. 3, frock part cutaway view.
The processing schematic diagram of Fig. 4, part.
Among the figure 1, part, 2, counterbore, 3, the frock part, 4, frock part centre bore, 5, top, 6, chuck.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
As shown in Figure 1, 2, a kind of processing parts 1 to be processed, this part has two end faces, and 4 counterbores 2 of each end face processing require the counterbore 2 of end face both sides correspondence should guarantee that procedure of processing is as follows on same axis:
1: give part 1 blanking, plane by drawing, rule, spile, drill centers, withstand centre bore with lathe centre 5, with chuck 6 clampings, car goes out part other end counterbore 2 simultaneously;
2: processing tool spare mills out the both ends of the surface of frock part as shown in Figure 3, and while centering 4, with lathe two top tops two centre bores 4, processes the cylindrical of frock part 3, and the diameter of cylindrical will be joined work with the diameter of manufactured counterbore 2;
3, as shown in Figure 4, frock part 3 and manufactured counterbore 2 are assembled into one in the mode of interference slightly, withstand frock part centre bore 4 with lathe centre 5, simultaneously with chuck 6 clamping parts 1, car goes out other end counterbore 2, has guaranteed the axiality of two counterbores like this;
4, repeat above-mentioned steps 1-3, car goes out other counterbore.
Claims (1)
1. the method for turning of a two ends band counterbore is characterized in that: this method is through the following step:
A, at an end face of institute's processing parts line centering, withstand centre bore with lathe centre, clamp with chuck simultaneously, car goes out counterbore in the other end of part;
B, process circular frock part according to counter bore hole diameters, in machining center hole, the center of circle of frock part, the diameter of frock part and counter bore hole diameters are joined work can form interference fit;
C, the frock part that processes and manufactured counterbore are assembled into one in the mode of interference slightly, withstand the centre bore of frock part with lathe centre, clamp part with chuck simultaneously, car goes out part other end counterbore.
