Abstract
The utility model relates to an excircle jig for a hollow shaft sleeve comprising a disc and a shaft. The center of the disc is provided with a mandrel hole. The shaft is through the mandrel hole in permanent connection with the disc, below the shaft is located a support in permanent connection with the shaft by bolts, the back end of the support is in permanent connection with the disc face, on two ends of the upper surface of the support is located a flat-faced locating plate with tapped holes, one lateral face of the support is surmounted by a lateral locating plate, the external side of which having a hook press plate connected with the support by bolts. Two ends of the shaft have center holes. The disc face above the shaft is surmounted by a balance block, the disc having a pin is connected with the lathe rotor shaft by the pin. When the hollw shaft sleeve is fixed by said jig, the excircle surface of hollw shaft sleeve forepart can be processed by the lathe or grinder at requried working accuracy and roughness.
Description
Technical field
The utility model relates to the clamp technology field, especially a kind ofly its cylindrical is added the cylindrical clamp for machining of used hollow shaft sleeve in man-hour on lathe or grinding machine to being loaded on hollow shaft sleeve on the train wheel, that have level and vertical reference face.
Background technology
Be loaded on the hollow shaft sleeve on the train wheel, its with big baseplane, side plane as reference for installation, anterior bearing set of hollow shaft sleeve and gear, the positional precision of its anterior cylindrical directly has influence on the gear meshing precision, therefore the axis of its anterior cylindrical has higher position degree requirement, and because the hollow shaft sleeve rear shape is irregular, therefore can't process on lathe and grinding machine, can only on vertical lathe, process, and low precision and the roughness requirement that can't satisfy processing parts of the machining accuracy of vertical lathe.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of cylindrical clamp for machining of hollow shaft sleeve, after utilizing this anchor clamps fixation hollow axle sleeve, can the machining accuracy and the roughness requirement of the anterior cylindrical of hollow shaft sleeve have been guaranteed on the lathe the anterior outer round surface of hollow shaft sleeve being machined or on grinding machine, carrying out grinding.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cylindrical clamp for machining of hollow shaft sleeve, have disk and mandrel, disc centre has the mandrel hole, mandrel is located in the mandrel hole and is fixedly connected with disk, the mandrel below is provided with bearing, propping up base rear end fixedlys connected with the disk end face, bearing connects by bolting with mandrel, the two ends, plane are fixed with the plane positioning plate on the bearing, the plane positioning plate is provided with screw, bearing one side is fixed with the side location-plate, and the arranged outside of side location-plate has the hook-type pressing plate, and the hook-type pressing plate is connected with bearing by bolt, there is centre bore at the mandrel two ends, the upper fixed that the disk end face is positioned at mandrel has balance weight, also is provided with on the disk and pulls pin, and disk connects with the lathe rotating shaft by pulling pin.
During use, hollow shaft sleeve is hung in the anchor clamps, workpiece is located on the plane positioning plate of anchor clamps and side location-plate with big baseplane, side plane, and the cylindrical center of workpiece just overlaps with the mandrel center of anchor clamps like this.Utilize hold-down bolt with workpiece planarization location and fastening with anchor clamps, the anchor clamps that workpiece will be housed afterwards winch to lathe or grinding machine, on the carbide alloy back dead centre at lathe or grinding machine two ends, realize location, no gap with the centre bore at anchor clamps mandrel two ends, thereby guaranteed the machining accuracy of workpiece.Pulling pin is used to connect lathe rotating shaft and anchor clamps, drives the anchor clamps rotation.Consider that from the manufacturability that anchor clamps are made these anchor clamps adopt many package assemblies, it is very little to be convenient to control centre's carpenters square by reconditioning plane positioning plate and side location-plate.Because bearing is in cantilever position,, improve the rigidity and the bearing capacity of bearing so bearing and mandrel are combined as a whole with bolt.Because of the workpiece rear shape is irregular, anchor clamps and workpiece are laid particular stress on respect to anchor clamps mandrel center again, so should do dynamic balance running when using first behind the anchor clamps clamping workpiece, realize the dynamic balancing of anchor clamps by the weight of adjusting balance weight.
The beneficial effects of the utility model are, after utilizing this anchor clamps fixation hollow axle sleeve, can the machining accuracy and the roughness requirement of the anterior cylindrical of hollow shaft sleeve have been guaranteed on the lathe the anterior outer round surface of hollow shaft sleeve being machined or on grinding machine, carrying out grinding.

The specific embodiment
The cylindrical clamp for machining of the hollow shaft sleeve of the present utility model shown in Fig. 1～5 has disk 1 and mandrel 2, disk 1 center has the mandrel hole, mandrel 2 is located in the mandrel hole with disk 1 and is fixedly connected by holding screw, mandrel 2 belows are provided with bearing 3, bearing 3 rear ends and disk 1 end face weld or are bolted to connection, bearing 3 and mandrel 2 connect by bolting, the two ends, last plane of bearing 3 are fixed with plane positioning plate 4, plane positioning plate 4 is provided with screw 41, bearing 3 one sides are fixed with side location-plate 5, the arranged outside of side location-plate 5 has hook-type pressing plate 6, hook-type pressing plate 6 is connected with bearing 3 by bolt, and there is centre bore 21 at mandrel 2 two ends, and the upper fixed that is positioned at mandrel 2 on disk 1 end face has balance weight 7, also be provided with on the disk 1 and pull pin 8, disk 18 connects with the lathe rotating shaft by pulling pin.
During use, hollow shaft sleeve is as shown in Figure 6 and Figure 7 hung in the anchor clamps, hollow shaft sleeve is with big baseplane, side plane location on the plane positioning plate 4 of anchor clamps and side location-plate 5, in the screw 41 on the hold-down bolt screw-in plane positioning plate 4, workpiece and anchor clamps are tightened together, as Fig. 8 and shown in Figure 9; The anchor clamps that workpiece will be housed afterwards winch to lathe or grinding machine, realize location, no gap with the centre bore 21 at anchor clamps mandrel 2 two ends on the carbide alloy back dead centre at lathe or grinding machine two ends, thereby have guaranteed the machining accuracy of workpiece.Pulling pin 8 is used to connect lathe rotating shaft and anchor clamps, drives the anchor clamps rotation.Because of the workpiece rear shape is irregular, anchor clamps and workpiece are laid particular stress on respect to anchor clamps mandrel 2 centers, so should do dynamic balance running when using first behind the anchor clamps clamping workpiece, realize the dynamic balancing of anchor clamps by the weight of adjusting balance weight 7.
