Abstract
The invention discloses a method for improving the machining efficiency and quality of a roll grinder. Rolling bearings are mounted on a grinder center frame of the roll grinder, so as to be contacted with the surface of a to-be-machined work piece; the rolling bearings are used for supporting the work piece to improve the grinding speed and precision during the machining. According to the invention, the rolling bearings are arranged on an upper sliding block body and a lower sliding block body of the grinder center frame to support the work piece, so that the work piece rotates to drive the bearing to roll during the machining of the grinder, compared with the traditional friction support, the method and the device have the advantages that the stability is excellent, when a large-scale work piece is machined, the acting force exerted by the work piece on the center frame is dispersed, a support piece bears uniform stress, the rigidity of the grinder center frame is improved, the high-speed stable and clearance-free rotation of the work piece is guaranteed, the grinding speed and precision during the machining can be greatly improved, and further the machining efficiency of the grinder is improved.
Description
Technical field
The present invention relates to a kind of method and device that the machine tooling effect is provided, especially a kind of method and device that improves roll grinder working (machining) efficiency and crudy.
Background technology
At present, the grinder center frame of existing large-scale roller grinding machine, what all adopt on its top shoe body and the downslide block is friction pair, it is not very large workpiece that this version is applicable to support volume and weight, when the workpiece volume and weight of processing is larger, some shortcomings just occur: owing to action of gravitation, workpiece friction pair wearing and tearing to top shoe and sliding block when rotating are accelerated, so that the surface of the work precision that processes can't meet the demands (1).(2) because the workpiece volume is larger, limited the linear velocity when friction pair supports, reduced the working (machining) efficiency of grinding machine.
Summary of the invention
The objective of the invention is: a kind of method and device that improves roll grinder working (machining) efficiency and crudy is provided, and it is applicable to process most of workpiece, and can improve grinding speed and the precision that adds man-hour, to overcome the deficiencies in the prior art.
The present invention is achieved in that the method that improves roll grinder working (machining) efficiency and crudy, rolling bearing is installed on the grinder center frame of roll grinder, rolling bearing is contacted with surface of the work to be processed, utilize the roller bearings workpiece, to have improved grinding speed and the precision that adds man-hour.
Grinding machine open type roller centre frame comprises shell body, and the arcwall face of case top is provided with downslide block and top shoe body outside, and the downslide block is connected with lower feeding mechanism by the gear that is installed in the shell body, and the top shoe body is connected with upper feeding mechanism; Be equipped with rolling bearing and roller axle sleeve at downslide block and top shoe body.
Rolling bearing and roller axle sleeve are fixed on downslide block or the top shoe body by bearing pin.
Operation principle of the present invention is, the axial feed of upper feeding mechanism controls top shoe body, and lower feeding mechanism is by the axial feed of gear control glide block, rolling bearing contact with surface of the work and plays a supporting role the suitable workpiece of processing different-diameter.
Owing to having adopted above-mentioned technical scheme, compared with prior art, the present invention adopts the up and down slide body at grinder center frame that rolling bearing is set, in order to supporting workpiece, make grinding machine add workpiece rotating drive in man-hour bearing element, friction-type stability of strutting system than the past is good, during the machining large workpiece, the active force of workpiece on centre frame disperses, support member is stressed evenly, has improved the rigidity of grinder center frame, has guaranteed the steady gapless rotation of Work piece high-speed, greatly improve the grinding speed and the precision that add man-hour, thereby improved the working (machining) efficiency of grinding machine.Method of the present invention is simple, easily implements, and institute's apparatus structure that adopts is compact, rationally distributed, easy to operate, economical and practical, especially suitable volume, weight, the axial workpiece that diameter is larger processed.
