Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 5, irregularly-shaped hole 6 is the through hole in irregular hole for middle part is circular hole two ends; As shown in Figure 1 to Figure 3, the processing and positioning device of this universal connecting shaft irregularly-shaped hole, comprises the vice 3 of clamping universal connecting shaft 2 axle head and supports the screw jack 1 of universal connecting shaft 2 bulb end; Comprise the location-plate 4 be located at below universal connecting shaft 2 irregularly-shaped hole 6, location-plate 4 is provided with the locating hole 5 with the circular hole coaxial of irregularly-shaped hole 6, and locating hole 5 and circle hole centreline overlap; Also comprise the alignment pin 7 coordinated with locating hole 5 and circular hole, such alignment pin 7 inserts in circular hole and locating hole 5, makes the irregular hole machined positioning datum in irregularly-shaped hole 6 two ends consistent, can ensure the axiality in irregular hole, irregularly-shaped hole 6 two ends.
Screw jack 1 is supported on universal connecting shaft 2 and establishes in the bulb bottom portion of irregularly-shaped hole 6; Screw jack 1 plays supplemental support effect, can adjust height, be horizontal to make universal connecting shaft 2; Universal connecting shaft 2 effectively can be prevented in process to move downward inclination simultaneously, ensure the irregularly-shaped hole precision of processing.
Universal connecting shaft 2 clamps by vice 3, and screw jack 1 plays supplemental support effect; First on universal connecting shaft 2, bore manhole, manhole is identical with circular hole aperture in the middle part of irregularly-shaped hole 6, bores the locating hole 5 identical with circular hole aperture on location-plate 4 simultaneously; Then irregular hole, top is processed; Upset universal connecting shaft 2, alignment pin 7, before Set and Positioning, inserts in manhole and locating hole 5, then is clamped by universal connecting shaft 2 with vice 3 by universal connecting shaft 2; Extract alignment pin 7 out, processing irregular hole, bottom, irregularly-shaped hole 6 machines.Adopt this positioner, the cooperation of alignment pin 7 and locating hole 5 and circular hole, make irregular hole, irregularly-shaped hole 6 two ends positioning datum consistent, the reliable positioning supports that irregularly-shaped hole 6 adds man-hour can be realized fast and effectively, ensure the axiality in the irregular hole of universal connecting shaft 2 irregularly-shaped hole 6 upper and lower side, and then ensure the machining accuracy in hole; Ensure that universal connecting shaft 2 two ends attaching parts are coaxial, bear torsion during universal connecting shaft 2 transmission consistent, universal connecting shaft 2 stable drive, improve the service life of universal connecting shaft 2.
