Abstract
The utility model relates to a roller tool which is arranged on a three-jaw chuck for processing outer thread. Each set of tool is composed of three roller heads, and each roller head is provided with a quarter bend iron, a bearing support and a shaft. The shaft is provided with a plurality of rolling blades, and both ends of each rolling blade are provided with gaskets and other elements, such as nuts for pressing the rolling blades, etc. The jaws on the three-jaw chuck can radial move to adjust the depth of the rolling thread when in rolling the thread, the three-jaw chuck can relatively turn corresponding to work pieces with the rotary of the machine tool of other power devices, and the work pieces can axially move in order to realize rolling the thread. The length of the processing thread can not be restricted by the thickness of the rolling tool, and the utility model is suitable for processing long threads without swarf.
Description
The utility model is a kind of chipless rolling tool of threading.
Existing general screw-rolling machine, the length of its rolled thread is no more than the thickness of cylindrical die roll.Therefore, screw-rolling machine is the longer screw thread that can't process above cylindrical die roll thickness.
The purpose of this utility model is for the longer screw thread of chipless processing.It is installed on the scroll chuck, by the degree of depth of adjusting rolled thread that moves radially of each claw of scroll chuck, by the rotation of lathe or other power set, the scroll chuck that die head with cylindrical-die roller is installed is rotated, and realizes the screw thread on the roll extrusion excircle of workpiece.
The mode of screw-rolling machine rolled thread is: the cylindrical die roll rotation is also done the radial feed motion, and workpiece and cylindrical die roll pure rolling realize rolled thread.When workpiece and rolled thread crop rotation pure rolling, has only a small amount of axial displacement.Therefore, the maximum length of screw-rolling machine rolled thread depends on the thickness of cylindrical die roll.
The utility model is the milled head that a cover is made up of three roller-heads, is installed in respectively on three claws of scroll chuck.After with the dop spanner claw radial dimension being adjusted, milled head rotates with respect to workpiece by scroll chuck, and workpiece can only axial displacement, just can realize the rolling and processing of screw thread.Therefore, the reach that it rolls out is not subjected to the restriction of rolling tool thickness, and depends on the length of machine tool guideway.
Description of drawings: accompanying drawing 1 is a front view, and accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1.
The part name of number in the figure representative is: 1-scroll chuck, the 2-support of bearing, 3-right angle bending iron, 4-end cap, 5-workpiece, 6-bearing cap, 7-axle, 8-end cap, 9-bearing, 10-packing ring, 11-roll extrusion blade, 12-straight pin, 13-nut, 14-screw, 15-internal head cover, 16-screw, 17-nut.
Feature of the present utility model is that every cover milled head is made up of three profiles and the essentially identical roller-head of size.Each roller-head has the roll extrusion blade 11 that several pieces shapes such as packing ring are housed on a right angle bending iron 3, support of bearing 2, two bearings 9, two bearing caps 6, axle 7, the axle 7 respectively, packing ring 10 is equipped with at roll extrusion blade 11 two ends, and the nut 13 that compresses roll extrusion blade 11 is arranged, screw 16 and the nut 17 of adjusting roll extrusion blade 11 axial dimensions are housed on the end cap 4.Two screws 14 of the support of bearing 2 and right angle bending iron 3 usefulness connect, and the straight pin 12 of location usefulness is housed.The roll extrusion blade 11 that is pressed on the axle 7 can join coaxial 7 rotations together.
Parts such as right angle bending iron 3, the support of bearing 2, axle 7, end cap 4 can be made of ordinary steel, and roll extrusion blade 11 needs to make of high-speed steel.
During the screw thread of different pitch of the utility model roll extrusion or external diameter, only need to change the roll extrusion blade 11 and the packing ring 10 of different-thickness, and adjust the angle of the support of bearing 2 and right angle bending iron 3, make it lead angle with workpiece 5 screw threads is identical and just can process.
Claims (1)
- A kind of die head with cylindrical-die roller is made up of three profiles and the essentially identical roller-head of size, is installed in respectively on three claws of scroll chuck, it is characterized in that:A. each roller-head is formed by parts such as right angle bending iron, the support of bearing, bearing, bearing cap, axle, roll extrusion blade, nuts.B. on the axle of each roller-head several pieces roll extrusion blades are housed, every roll extrusion blade shape such as packing ring.
