Description
Technical field
The utility model relates to the adjustable composite boring cutters of a kind of ladder endoporus, belongs to aperture knife tool technical field in ladder.
Background technology
Automobile electric steering column belongs to electronic mechanical integrated product, is widely used in automobile steering system.The worm gear that automobile electric steering column uses a kind of material to be aluminium alloy, worm speed-down engine housing, for precision positioning worm gear, worm screw, carry the component of each moving component.
For guaranteeing the installation precision of worm bearing and motor, the accuracy of manufacture of the endoporus of reducer shell all needs to be less than 7 grades, and usually processes 3 endoporus needs 6 standard boring cutter, and each endoporus needs thick, each one of fine boring cutter.Although so well reach the standard of interior hole machined, need frequently to change cutter, processing work is comparatively consuming time, efficiency is lower.
Summary of the invention
The purpose of this utility model is: provide a kind of structure simple, practicality is good, and cost performance is high, can realize the adjustable composite boring cutters of ladder endoporus that porous is processed simultaneously.
The technical solution of the utility model is:
The adjustable composite boring cutters of a kind of ladder endoporus, it is made up of cutter hub, handle of a knife, adjustment block and blade; It is characterized in that: one end of cutter hub is provided with handle of a knife; The other end of cutter hub is provided with multidiameter; Each multidiameter termination is respectively arranged with adjustment groove; Be provided with adjustment block by lock-screw in adjustment groove, described adjustment block termination is provided with blade by clamp-screw, and adjustment block end tail is provided with length adjustment screw, and the middle part of adjustment block is provided with diameter adjustment screw.
The invention has the advantages that:
During composite boring cutter work that this ladder endoporus is adjustable, handle of a knife is connected with machine tool chief axis, adjustment block is arranged on the adjustment groove of cutter hub by lock-screw activity, the adjustment of ladder diameter of bore and the degree of depth can be realized by adjustment length adjustment screw, diameter adjustment screw.Have that efficiency is high, cost is low, the feature that axiality is good, be specially adapted to hole machined in workpiece ladder and use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the amplification at the A place of Fig. 1.
In figure: 1, cutter hub, 2, handle of a knife, 3, adjustment block, 4, blade, 5, length adjustment screw, 6, diameter adjustment screw; 7, groove is adjusted, 8, lock-screw.
Detailed description of the invention
The adjustable composite boring cutters of this ladder endoporus is made up of cutter hub 1, handle of a knife 2, adjustment block 3 and blade 4.One end of cutter hub 1 is provided with handle of a knife 2; The other end of cutter hub 1 is provided with multidiameter; Each multidiameter termination is respectively arranged with adjustment groove 7; By lock-screw 8, adjustment block 3 is installed in adjustment groove 7.Adjustment block 3 termination is provided with blade 4 by clamp-screw, and adjustment block 3 end tail is provided with length adjustment screw 5, and the middle part of adjustment block 3 is provided with diameter adjustment screw 6.
During the work of this ladder endoporus is adjustable composite boring cutter, being connected with machine tool chief axis by handle of a knife 2, in the course of work, the adjustment of ladder diameter of bore that workpiece processes and the degree of depth can being realized by adjusting length adjustment screw 5 and diameter adjustment screw 6.And because blade 4 is on same cutter hub 1, added to workpiece shoulder hole man-hour, the existing concentricity problem produced because of the resetting of lathe can be effectively prevent.Shorten process time simultaneously, have that efficiency is high, cost is low, the feature that axiality is good, is particularly suitable for the processing of ladder ladder endoporus.
