The specific embodiment
Embodiment.Guarantee the processing method of axial workpiece centre bore and cylindrical concentricity.As shown in Figure 1.An electronic roller clamping device is installed on the guide rail of common bench lathe, electronic roller clamping device is provided with driving wheel 5, support roller 7 and pinch roller 9, the part 15 of needs processing is placed between driving wheel 5 and the support roller 7, make the cylindrical of part 15 and driving wheel 5 and support roller 7 tangent, and part 15 is compressed with pinch roller 9, motor 3 drives driving wheel 5 rotations, by driving wheel 5, support roller 7 and 9 three automatic centering of pinch roller, make part 15 rotations, utilize centre drill 17 feeds of installing on the tail stock then, the centre bore 16 of processing parts 15.Described pinch roller 9 can move up and down, and upwards unclamps part 15, clamps part 15 downwards; Pinch roller 9 is installed in the end of seesaw 8, the middle part of seesaw 8 is hinged on the fixture mount 2, be hinged with the eccentric wheel 11 of band handle 10 on the fixture mount 2 of seesaw 8 afterbodys below, be provided with spring 12 between seesaw 8 and the fixture mount 2, under the effect of eccentric wheel 11, make pinch roller 9 being pressed on the part 15 tightly, part 15 is clamped, pull handle 10 and can unclamp part 15.
Operation principle of the present invention and process
Because the cylindrical of part generally all is to adopt a clamping time processing, for the required precision of the concentricity≤0.05mm of the centre bore that guarantees part and part cylindrical, so just must find the center of circle of cylindrical accurately.The present invention utilizes driving wheel 5, support roller 7 and pinch roller 9 tangent with the cylindrical of part 15, utilize 3 principles of determining the cylindrical center of circle automatically on the cylindrical, so in process, have higher concentricity between centre bore and the cylindrical, can satisfy the required precision of part concentricity≤0.05mm fully.In the debug process of device, guarantee that two driving wheels 5 are parallel with the guide rail of lathe with two support rollers 7, and guarantee that the center of circle of part 15 is concentric with the centre drill 17 on the lathe tailstock.Adding man-hour, pulling handle 10, under the effect of eccentric wheel 11 pinch roller 9 is being lifted, part 15 is placed between driving wheel 5 and the support roller 7, decontroling handle 10 then, under the effect of eccentric wheel 11, pinch roller 9 clamps part 15.Motor 3 drives part 15 rotations by driving wheel 5.By being installed in centre drill 17 feeds on the tail stock, machining center hole 16 on part 15.
According to the employed electronic roller clamping device of the processing method of aforesaid assurance axial workpiece centre bore and cylindrical concentricity, it comprises electric machine support 1 and fixture mount 2, and motor 3 is installed on the electric machine support 1; Through bearing 4 two driving wheels 5 are installed on the fixture mount 2, motor 3 is connected with driving wheel 5 through decelerator 6; Parallelly on the fixture mount 2 two support rollers 7 are installed through bearing 4 with driving wheel 5; The middle part of the top of fixture mount 2 and seesaw 8 is hinged, and the end of seesaw 8 is provided with one or two pinch roller 9, is hinged with the eccentric wheel 11 of band handle 10 on the fixture mount 2 of seesaw 8 afterbodys below, is provided with spring 12 between seesaw 8 and the fixture mount 2.Described anti-electric machine support 1 is corresponding with the guide rail of common bench lathe with fixture mount 2 bottom shapes, and is provided with pressing plate 13, and pressing plate 13 is provided with trip bolt 14.Described pinch roller 9 can use the zanjon bearing directly to use as pinch roller 9.
