Abstract
A cylindrical combination grinding wheel is formed by combination of a cutter head (1) and a base body (2) via a screw thread connection. Wherein screw threads provided by the base body (2) and the cutter head (1) are provided with the same tooth shape, diameter, and pitch, opposite rotation directions, in mutual match, and form a group, and the cutter head (1) comprises a cutter bar (21) with the bottom end with screw threads, and an abrasive wheel ring (22) attached at the top of the cutter bar. The cylindrical combination grinding wheel is advantageous in that, since the cutter head and the base body can be separately machined, the base can be used as a standard component for storage, facilitating production organization; the cutter head performs post finishing with the abrasive wheel ring as the reference, reducing machining difficult and improving work efficiency.
Description
Technical field
The present invention relates to the grinding tool field, especially a kind of cylindrical combined grinding wheel.
Background technology
Grinding is the method for utilizing the grinding tools such as emery wheel of High Rotation Speed that processing work is processed, as the cylinder grinding wheel of one of important grinding tool, is widely used in the processing of the materials such as metal, glass, pottery, magnetic material, crystal.Cylinder grinding wheel generally is comprised of matrix and emery wheel ring, and its production process has three kinds, and the first is processed first matrix, then the mode by hot pressing will contain abrasive material, bond and additive the powder pressing sintering at matrix, form product; It two is first machining matrixes respectively, hot pressing or the rear sintering processing emery wheel ring of colding pressing, and then the mode by bonding, welding is with matrix and the emery wheel ring formation product that combines as a whole; It three is a kind of methods not too commonly used, patent ZL94247095.8 discloses a kind of tubular abrasive wheel of screwbolt fastening, be provided with nut in the emery wheel ring end face on one side, nut with spin by the ring flange screw thread and cylinder grinding wheel be fastened on the ring flange, form final products.
High for requirement on machining accuracy, particularly require cylinder grinding wheel less than 0.01mm to adding to beat man-hour, must carry out rear finishing to emery wheel, to guarantee the concentricity of matrix assembling screw thread or pilot hole and emery wheel ring.Existing common process is, the pilot hole on the matrix or assembling screw thread carry out rear finishing by the mode of grinding or electric spark to cylinder grinding wheel as benchmark.Because cylinder grinding wheel emery wheel ring close with the abrasive hardness of abrasive hardness and trimming wheel, even also harder than the abrasive hardness of trimming wheel, so trimming wheel consumption is very fast and trimming speed is excessively slow; Though as adopt electric machining to repair efficient and significantly improve, consumption of electrode is also little, the high temperature that electric machining produces is ablated serious to emery wheel ring abrasive material, shortened the service life of emery wheel.
Summary of the invention
The utility model purpose is, when solving the electric machining finishing emery wheel ring abrasive material ablated and the low problem of the very fast dressing efficiency of trimming wheel consumption during grinding dressing, provides a kind of requirement on machining accuracy height need carry out the cylindrical combined grinding wheel of rear finishing.
The utility model discloses a kind of cylindrical combined grinding wheel, it is characterized in that this cylinder grinding wheel is combined by matrix, cutter head.Matrix, cutter head institute is threaded be that tooth form, diameter are identical with pitch, and direction of rotation is opposite, mutual a group of mating.Matrix, cutter head can closely cooperate and join together by screw thread.Cutter head is comprised of the screwed knife bar in bottom and the emery wheel ring that is attached to the knife bar top.Because cylindrical combined grinding wheel of the present utility model can be with cutter head and matrix separate machined, particularly take with the emery wheel ring of abrasive material as benchmark processing.When guaranteeing machining accuracy, in the time of can reducing the electric machining finishing emery wheel ring abrasive material ablated and the consumption of trimming wheel during grinding dressing, thereby improve dressing efficiency.
The utility model cylindrical combined grinding wheel process is as follows:
(1) matrix is machined to finish size;
(2) knife bar is except screw thread and cylindrical plus tolerance, and other position is machined to finish size;
(3) to the knife bar top, or knife bar and emery wheel ring powder hot pressing one-shot forming be attached to the knife bar top with the emery wheel ring to the emery wheel ring that will produce in advance, forms cutter head by bonding or solder attachment;
(4) the emery wheel ring is repaired, and as benchmark, processing nut arbor outside diameter and knife bar bottom be threaded into given size, form the cutter head of finishing completion;
The matrix that (5) will be machined to finish size and the cutter head of finishing completion and mode by thread connection form cylindrical combined grinding wheel;
Though conventional cylinder grinding wheel complexity and the manufacturing procedure of cylindrical combined grinding wheel structure of the present utility model is loaded down with trivial details, but because take the emery wheel ring that trims as benchmark the processing cutter head, reduced the trim amount of emery wheel ring, improved operating efficiency, but while cutter head and matrix separate machined, matrix can be used as the standard component stock, is convenient to organization of production.
