Abstract
The present invention relates to the multiple externally threaded rolling tool of a kind of semi-automatic rapid processing, it is made up of eccentric shaft, hollow gear shaft, adjustment dish, main body, rolling cutter, handle, pull bar, length stop, slide block, cover plate, shell taper shank etc., have simple to operate, the processing diameter range is big, adjustable length, the location rapidly, processing work precision height, characteristics such as intensity is good.The most suitable being contained in of this instrument processed various external screw threads on the engine lathe, its working (machining) efficiency and quality and special-purpose screw-rolling machine or thread rolling machine are roughly the same.
Description
The present invention relates to the multiple externally threaded instrument of a kind of semi-automatic rapid processing, particularly utilize axial feed rolling method to process, be adapted at most on engine lathe or the relevant device,, process various screw threads as a kind of instrument.
The instrument of existing threading is with circular die or threading tool.Criticize or odd-pitch screw though can process mark with threading tool on engine lathe, work efficiency is low, and labour intensity is big.Adopt circular die, generally can only by hand or make externally threaded machining on lathe, different-diameter will be changed different circular dies and anchor clamps, and tool-changing speed is slow, work efficiency is low, quality is unstable.According to disclosed UK Patent Application in 1980: the GB1569058(applying date: on May 24th, 1978, application number: 22126/78) described " machine tool installation component ", this invention is a kind of revolution clamping apparatus that is installed on the lathe tailstock, three screw die are housed on its rotating disk, regulate rotating disk and can process the external screw thread of three kinds of different-diameters respectively, but withdrawing inconvenience, the crudy shakiness also produces a large amount of smear metals.
Task of the present invention is will provide a kind of can semi-automatically process various externally threaded instruments on engine lathe or relevant device, as long as the pitch thread form of workpiece is identical, needn't change cutter and just can process the external screw thread of multiple diameter, and working (machining) efficiency and quality and special-purpose screw-rolling machine or thread rolling machine are roughly the same.
Task of the present invention is achieved in that adorns an adjustment dish in indicating the main body of graduation mark, the outer surface of adjustment dish has a scale index line, there is axis hole uniform more than two inside, is used for installing the corresponding eccentric shaft of quantity, and the adjustment dish is used for adjusting the diameter of processed screw thread.Be used for thread-rolling rolling cutter and be installed in eccentric shaft, the other end of eccentric shaft is contained on the cover plate, should be able to freely rotate after eccentric shaft installs.Cover plate is connected with the adjustment dish with bolt.The gear parts that is contained in the hollow gear shaft in the main body is meshed with the gear parts of eccentric shaft, and eccentric shaft is synchronously rotated; Participate in the relative position of adjusting the rolling cutter.Before the processing, turn adjustment dish, driving eccentric shaft revolves round the sun around hollow gear shaft, owing to the effect of tension spring or handle, hollow gear shaft is motionless, under the effect of meshing gear simultaneously, make eccentric shaft make spinning motion, so just can regulate the relative position of eccentric shaft arbitrarily, thereby regulate the relative position of rolling cutter according to different diameters of work.One end of hollow gear shaft has a mouth, can be a square orifice, cooperates with slide block, presses and to do in the cavity that spring is contained in taper shank, and its end contacts with slide block.Handle and pull bar also are housed on the hollow gear shaft, and turning handle can drive hollow gear shaft and rotate, and allows slide block enter in the square orifice of hollow gear shaft, makes instrument in running order.Connect a tension spring on the pull bar, can play a part to reset.The length stop is used to limit the length of processing other part, and it is positioned at the inner chamber of hollow gear shaft.
Utilize the present invention, the kind of screw thread to be processed can be selected arbitrarily within the specific limits, simple to operate, the location is rapid, the workpiece accuracy height, and intensity is good, and the back rolling cutter that puts in place can unclamp automatically, and is safe and reliable, can increase substantially work efficiency.

Describe the details and the working condition of the concrete device of the present invention's proposition in detail below in conjunction with accompanying drawing.
A kind of concrete device of the present invention is to be fixed on the main body (2) with spiral form by a taper shank (1), taper shank (1) has a cavity, put a compression spring (3) in the chamber, one end of compression spring (3) touches mutually with slide block (4), the other end of slide block (4) touches mutually with length stop (5), and block hollow gear shaft (6) in working order down and go up in the square orifice, length stop (5) is contained in the middle of the hollow gear shaft (6), can do axially-movable.Hollow gear shaft (6) is installed on the main body (2), and pass the centre bore of adjustment dish (9), handle (7) is contained on the hollow gear shaft (6) by the opening of main body (2), one end of pull bar (8) also is fixed on the hollow gear shaft (6), with reference to Fig. 2, its other end links to each other with tension spring (17), and the other end of tension spring (17) is fixed on the main body (2).Adjustment dish (9) is contained on the main body (2), be fixed on the main body (2) with fastening Luo Ding (10), a graduation mark index line (18) is corresponding with main body (2) high scale (19) with reference to having on Fig. 3 adjustment dish (9), three uniform axis holes are arranged on the adjustment dish (9), one end of three eccentric shafts (11) is contained in respectively in three axis holes, rolling cutter (13) is contained on the eccentric shaft on (11), gears engaged on gear (12) on the eccentric shaft (11) and the hollow gear shaft (6), by the engagement between gear, make three rolling cuttves (13) do to rotate synchronously.The other end of eccentric shaft (11) is contained on the cover plate (14), and cover plate (14) is connected with adjustment dish (9) by bolt (15).Between cover plate (14) and the adjustment dish (9) shell (16) is arranged.
Process.When identical and the workpiece that diameter is different of processing pitch, loosening trip bolt (10) is regulated adjustment dish (9) and is made its scale index line (18) corresponding with scale (19) on the main body (2); Should change cutter when processing the workpiece of different pitch: during processing different length workpiece, adjustable length stop (5).This tool work time-division duty and original state.Turning handle (7) can drive hollow gear shaft (6) and rotate, make three rolling cuttves (13) do to rotate synchronously by gears engaged, block hollow gear shaft (6) up to slide block (4), when hollow wheel gear (6) can not be rotated again, instrument is in running order, in the process, when an end of workpiece and length stop (5) are inconsistent, slide block (4) is released the square orifice of hollow wheel gear (6) by length stop (5), this rotates hollow gear shaft (6) to tension spring (17) by pull bar (8), pass through gears engaged, rolling cutter (13) is unclamped, handle (7) is also got back to original position automatically simultaneously, and this moment, instrument was got back to original state, finished a course of work.
