Abstract
The utility model relates to a machining centering device, which comprises a base, a body, a maintaining sleeve, a long screw and a press plate. The machining centering device is characterized in that the maintaining sleeve is arranged in the body, the body and the base are connected with each other through the long screw; and the two ends of the maintaining sleeve are respectively provided with a tapered hole, and at least four steel balls are uniformly arranged in either tapered hole. The utility model has the advantages of simple structure, low cost, high centering accuracy after assembly of the parts, convenient assembly, low reject rate of the parts and good service effect.
Description
Technical field
The utility model relates to a kind of centring means, is specifically related to the high-precision fixed center device of machining pearl pipe.
Background technology
At present the automatic tool changer of the higher numerical control machining center of class all adopts globoid cam pearl tubular construction in the machine industry, the pearl pipe is the driven member of globoid cam, six needle bearings that are installed in above it are fitted on the space curved surface of globoid cam, the pearl pipe is installed on the pearl base by two taper roll bearings, can only be rotated motion, can not axial float.So, when doing, the pearl plumber will bear very big impact moment, and in order to guarantee the accurate contact of six needle bearing globoid cams, six the needle bearing installing hole angles required precision above it is very high.The processing centring means that adopts has chuck clamping, dedicated elas-tic chuck, hydraulic pressure swelled chuck etc. at present, and these clamping device processing back precision do not reach requirement, the percent defective height; Clamping inconvenience during product processing, efficient is low, and speed is slow, the expense height.
Summary of the invention
The purpose of this utility model overcomes above-mentioned existing shortcoming exactly, provides a kind of cost low, simple in structure, precision height, handling ease, the machining centring means that percent defective is low.
The utility model comprises base, body, maintainance set, long bolt and pressing plate, it is characterized in that: described maintainance set places body, and body is connected by long bolt with base; The maintainance set two ends are provided with taper hole, are evenly equipped with at least 4 steel balls in its taper hole.
The utility model is simple in structure, cost is low, centering precision height behind the parts fixation, and convenient mounting and clamping, the part percent defective is low, and result of use is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a B-B view among Fig. 1.
Fig. 3 is the partial enlarged drawing of Fig. 1.
Among the figure: 1, base, 2, long bolt, 3, baffle plate, 4, steel ball, 5, the spline pin, 6, maintainance set, 7, body, 8, pressing plate, 9, screw, 10, part, 11, packing ring, 12, taper hole.
The specific embodiment
Machining centring means by base 1, body 7, maintainance set 6, long bolt 2 constitute is provided with taper hole 12 at maintainance set 6 two ends, is evenly equipped with 6 steel balls in its taper hole 12.Maintainance set 6, steel ball 4 usefulness baffle plates 3 and pressing plate 8 are fixed on the body 7, are positioned on the base 1, carry out thread connection by long bolt 2 and body 7.
The location cylindrical of part 10 is placed in the maintainance set 6, the cylindrical two ends are positioned by steel ball 4 contacts, and end face rests on the pressing plate 8, and part 10 upper ends are fixed with open washer 11 and long bolt 2, part 10 clamping in whole process is reasonable, convenient and swift.Adopt the cylindrical two ends by the mode that steel ball 4 roll extrusion contact positions, can realize not having gap point contact location, guaranteed part 10 positioning accuracies, the positional precision in 6 uniform holes can reach requirement after part processing was finished.
