Abstract
The utility model discloses a long filament pole thread processing device belongs to the cutter field that is used for lathe or boring machine, including spring sleeve, cutter arbor and sword row, spring sleeve cavity, the sword is arranged and the cutter arbor is connected, the cutter arbor lies in spring sleeve and cutter arbor external diameter and the cooperation of spring sleeve diameter, sword row keeps away from cutter arbor one end and is connected with the cutter, set up porosely on the sword is arranged, the downthehole spring catch that is provided with, the spring catch includes a plurality ofly, sword phenomenon and machining precision height can effectively be avoided pricking for this patent application of spoon shape by the sword before the cutter.
Description
Technical field
The utility model relates to the cutter field for lathe or boring machine, is specifically related to a kind of long lead screw thread machining device.
Background technology
Screw mandrel is gyration is converted into rectilinear motion or is the ideal product of gyration by transform linear motion.Screw mandrel is the actuated element that machine tool and precision optical machinery the most often use, and its major function converts rotary motion to linear movement, or torque axis is changed into axial repeated action power, has high accuracy, invertibity and high efficiency feature concurrently simultaneously.In mechanical processing industry, particularly during Vehicle Processing major axis, usually need to process long screw screw thread.In process, because helical pitch is large, allowance is large, so easily vibrate man-hour adding.Add with normal threading tool man-hour easily can cause knife phenomenon because of vibration, workpiece is trembled, and distortion, cutter is impaired, and machining accuracy not easily ensures.And because there is knife phenomenon, force processing to stop, have impact on working (machining) efficiency.
Utility model content
The purpose of this utility model is providing a kind of machining accuracy high and is avoiding the long screw thread machining device of knife phenomenon.
For achieving the above object, the technical solution of the utility model is as follows: a kind of long screw thread machining device, comprises spring spool, knife bar and blade row; Described spring spool hollow; Described blade row is connected with knife bar, and described knife bar is positioned at spring spool and knife bar external diameter and spring spool minor diameter fit; Described blade row is connected with cutter away from knife bar one end; Described blade row is offered porose, be provided with spring catch in described hole, described spring catch comprises multiple, and described cutter front edge is spoon shape
Operation principle of the present utility model is: spring spool internal diameter and knife bar major diameter fit, knife bar penetrates spring spool.Lathe tool platform compresses knife bar, and blade row plays a part balanced cutting power and absorbing in process.Blade row is offered spring pin hole, in spring pin hole, has been provided with spring catch, the effect of balanced cutting power and absorbing can have been played, and spring catch can have been changed according to different actual conditions, played the effect of adjustment.
The beneficial effects of the utility model are as follows: on blade row, offered two holes, hole is provided with two spring catch, compared with traditional rigidity knife bar, this blade row spring catch in process can play good absorbing effect, so this blade row has the effect well playing balanced cutting power and absorbing, so can overcome the problem of the vibration that long screw causes in process preferably.Roughing tool front edge wears into a spoonful shape, adopts layered cutting, thus improve the performance of cutting time rough turn, have larger chip space, chip, to lathe tool central flows, forms spherical iron filings, chip removal is smooth, and workpiece can not because chip removal resistance is excessive or winding causes vibration and distortion.
Further, described blade row and knife bar are structure as a whole, and structure is simple, easily manufactured, has saved cost.
Further, it is protruding that described blade row side arranges the circular arc extending blade row body sidewall, arranges circular arc projection and can increase blade row body thickness, ensure that the intensity of blade row body, is conducive to improving service life.
Further, described Tool in Cutting angle of cutting edge is 12 ° ~ 15 °, and cutting edge is sharp.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model long screw thread machining device embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: 1-workbench; 2-spring spool; 3-second spring catch; 4-cutter; 5-blade row; 6-first spring catch; 7-screw; 8-knife bar.
Embodiment is substantially as shown in Figure 1: a kind of long screw thread machining device, comprises spring spool 2, knife bar 8 and blade row 5; Knife bar 8 is positioned at spring spool 2 and knife bar 8 external diameter and spring spool 2 minor diameter fit; Blade row is connected with cutter away from knife bar one end; Blade row 5 offers two holes, in hole, be respectively arranged with the first spring catch 6 and the second spring catch 3.Cutter 4 front edge is spoon shape.Blade row 5 and knife bar 8 are structure as a whole, and structure is simple, easily manufactured, has saved cost.It is that circular arc is protruding that blade row 5 body sidewall is extended in the setting of blade row 5 side, and arranging circular arc projection can increase thickness, also ensure that the intensity of blade row, is conducive to the raising service life of blade row body.Cutter 4 cutting edge anterior angle is 15 °, and cutting edge is sharp.
Spring spool 2 internal diameter and knife bar 8 major diameter fit, knife bar 8 penetrates spring spool 2.Lathe bench 1 compresses knife bar 8, and blade row 5 plays a part balanced cutting power and absorbing in process.Blade row 5 offers spring pin hole, has been provided with the first spring catch 6 and the second spring catch 3 in spring pin hole, the effect of balanced cutting power and absorbing can be played, and spring catch can have been changed according to different actual conditions, play the effect of adjustment.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
