Abstract
The utility model discloses a rolling cutter. The rolling cutter comprises a cutter shank and a steel ball and is characterized in that a pressing strip is arranged at one end of the cutter shank; a gap is formed in the pressing strip; the steel ball is arranged in the gap; a bearing is correspondingly arranged below the steel ball; and the bearing is arranged on the cutter shank. According to the rolling cutter, the cutter shank is arranged on a cutter rest of a lathe, a workpiece is rotated at high speed, an inner hole of the workpiece is tightly attached to the steel ball 4, and the steel ball 4 and the bearing 5 are driven to rotate quickly, so that the steel ball can roll the surface of the inner hole in the workpiece continuously until the inner hole of the workpiece is smooth, and machining of the inner hole is finished.
Description
Technical field
The utility model relates to a kind of improvement invention of roll extrusion cutter, particularly be a kind of roll extrusion cutter that is used for the processing work endoporus.
Background technology
In mechanical industry, if the spare and accessory parts of processing endoporus smoother are generally wanted to get on the bus the endoporus of workpiece blank at lathe earlier; With fine sandpaper endoporus is polished then; Make bore area smooth, so not only need artificial polishing, and the time of polishing is long; Operating efficiency, production cost is high.
Summary of the invention
In view of the existing technical problem of background technology, the utility model technical problem to be solved provides a kind of roll extrusion cutter that improves workpiece endoporus grinding efficiency.
In order to solve the problems of the technologies described above; The utility model adopts following scheme to realize: this kind roll extrusion cutter, include handle of a knife and steel ball, and it is characterized in that an end of said handle of a knife is equipped with a press strip; Said press strip is provided with a breach; Said steel ball places in this breach, and the below that said steel ball is corresponding is provided with bearing, and said bearing is installed on the handle of a knife.
The handle of a knife of the utility model can be fixed on the knife rest of lathe, after the lathe tool on the knife rest is good with the endoporus car of workpiece, need workpiece not disassembled; Can be directly the roll extrusion swivel on the knife rest to processed workpiece, and the workpiece endoporus is carried out roll extrusion by the steel ball on the roll extrusion cutter, make the workpiece endoporus reach smooth effect of uniform; So; Not only improve the speed of polishing, reduced manually-operated, and workpiece need not to change lathe and just can polish; Thereby avoided occurring the problem of endoporus and cylindrical decentraction, improved production efficiency and product quality because of workpiece conversion lathe; And, can regulate the position of roll extrusion cutter and workpiece to be machined endoporus through moving the knife rest on the lathe, and so adopt same roll extrusion cutter just can process the workpiece endoporus of different size, provide cost savings greatly, brought economic interests to producer.
Description of drawings
Further describe the operation principle and the relevant details of the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
With reference to accompanying drawing, this kind roll extrusion cutter includes handle of a knife 1 and steel ball 4; One end of said handle of a knife 1 is equipped with a press strip 2, and said press strip 2 is provided with a breach 3, and said steel ball 4 places in this breach 3; Said steel ball 4 corresponding belows are provided with bearing 5, and said bearing 5 is installed on the handle of a knife 1.
When the utility model uses, handle of a knife 1 is fixed on the knife rest of lathe, processed blanking inner hole after the lathe tool car on the lathe is good, swivelling tool-holder; Make the cutter head of roll extrusion cutter, this end that steel ball 4 promptly is installed turns to the endoporus of workpiece to be machined, adjusts the position of steel ball 4 and workpiece endoporus then; Promptly move the little supporting plate of lathe, make steel ball 4 be close to the endoporus of workpiece, after this just can start the lathe self-acting feed; Work piece high-speed rotates, and workpiece endoporus and steel ball 4 fit tightly, and drives steel ball 4 and bearing 5 quick rotation; Steel ball ceaselessly carries out roll extrusion to the workpiece bore area like this, and is smooth until the workpiece endoporus, accomplishes endoporus processing.
