Abstract
The utility model discloses an improved center support, which comprises an annular frame and at least three groups of positioning mechanisms uniformly distributed on the inner wall of the annular frame; each positioning mechanism comprises a telescopic supporting rod and a jacking head arranged on the telescopic supporting rod, and a ball bearing is arranged on the jacking head through a bearing pin; during machining, a part to be machined is placed between the ball bearings of the center support, and the telescopic supporting rod is adjusted according to the diameter of the part to be machined, so that the ball bearings are tangent with the circumference of the part to be machined; and when the part is rotated, rolling friction is formed between the part and the ball bearings, so that the friction force is greatly reduced, the part cannot wear, and the machining accuracy is improved.
Description
Technical field
The utility model relates to a kind of center bearing bracket to large-scale long shaft processing location.
Background technology
Utilize lathe that large-scale long shaft class part and large-scale central hole axle are added man-hour; The capital is used center bearing bracket large-scale long shaft class part and large-scale central hole axle is positioned; The tradition locating rack is employed in location, three tops is set on the toroidal frame inwall; It is arc surface that the top is adopted processing of copper or steel and end face usually, utilizes the arc surface location large-scale long shaft class part of top.The shortcoming of this localization method:
1, top and workpiece coefficient of friction are big, are easy to wearing and tearing, cause the machining accuracy deviation.
2, stability is not strong, and rotating speed can not be too high.
The utility model content
The goal of the invention of the utility model is to overcome the defective of prior art, and the center bearing bracket of a kind of machining accuracy height, good stability is provided.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme, a kind of improvement center bearing bracket; Comprise that toroidal frame and at least three groups are evenly arranged in the detent mechanism on the toroidal frame inwall, said detent mechanism comprises the retractable supports bar and is installed in the top on the retractable supports bar that said top is provided with ball bearing; Said ball bearing is installed on the top through bearing pin, adds man-hour, between the ball bearing with part centering support to be processed; According to the diameter of part to be processed, regulate the retractable supports bar, make the circumference of ball bearing and part to be processed tangent; When part rotates, form rolling friction between part and the ball bearing, frictional force reduces greatly; Avoid parts depreciation, improve the precision of workpiece.
Further, said ball bearing is two ball bearings, and contact area increases between bearing and the workpiece, increases stability.
Further, said ring support comprises first support and second support, and a side of said first support and second support is articulated and connected, and opposite side is fixedly connected through screw, during workpiece loading and unloading, opens the screw of a side, and workpiece is easily put into.
The beneficial effect of the utility model:
When 1, processing object, the top bearing rotates with object, and rolling friction replaces sliding friction, has reduced the coefficient of friction of object significantly.
2, duplex bearing has improved the stability of workpiece, and the lathe rotating speed also improves thereupon, thereby has improved production efficiency.
3, machining accuracy is more accurate.
Description of drawings
Fig. 1 is the structural scheme of mechanism of the utility model.
Fig. 2 is the utility model top structure sketch map.
The specific embodiment
Shown in Fig. 1-2; A kind of improvement center bearing bracket comprises that toroidal frame 1 and at least three groups are evenly arranged in the detent mechanism on toroidal frame 1 inwall, and said detent mechanism comprises retractable supports bar 3 and is installed in the top 2 on the retractable supports bar 3; Top 2 is provided with ball bearing 21; Said ball bearing 21 is installed on the top 2 through bearing pin 22, and said ball bearing 21 is two ball bearings, and said ring support 1 comprises first support and second support; One side of said first support and second support is articulated and connected, and opposite side is fixedly connected through screw 4.Add man-hour, between the ball bearing with part centering support to be processed, according to the diameter of part to be processed; Regulate the retractable supports bar, make the circumference of ball bearing and part to be processed tangent, when part rotates; Form rolling friction between part and the ball bearing; Frictional force reduces greatly, avoids parts depreciation, improves the precision of workpiece.
Above embodiment is only in order to the technical scheme of explanation the utility model but not to its restriction, the specific embodiment of the utility model is made amendment or the part technical characterictic is equal to replacement; And not breaking away from the spirit of the utility model technical scheme, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
Claims (3)
1. improve center bearing bracket for one kind; Comprise that toroidal frame and at least three groups are evenly arranged in the detent mechanism on the toroidal frame inwall; It is characterized in that; Said detent mechanism comprise the retractable supports bar be installed in the top on the retractable supports bar, said top is provided with ball bearing, said ball bearing is installed on the top through bearing pin.
