Description
Technical field
The utility model is related to spindle reverse taper holes processing technique fields, are specifically related to spindle reverse taper holes
Processing clamp for machining.
Background technology
Spindle is the important safety part in automobile steering system, and function is to transfer and bear automotive suspension system
System load, supporting simultaneously with runner hub around stub rotate and make motor turning, and affect Riding Stability of Automobile, security and
Steering sensitivity.
Ball pin hole takes reverse taper holes to design more under the passenger cars knuckle such as SUV, has registration, connection reliable lock etc.
Advantage.So-called " reverse taper holes " refer to compared with tool feeding direction, and taper hole apertura lateralis is small, inside face is big, therefore machine power can not
Realize that taper reamer autofeed and withdrawing, difficulty of processing are big.General taper hole roughness requirements Ra1.6, the conical surface are examined using red lead
Look into contact area >=75%.
Following two modes are mainly used in conventional processes：Traditional back taper hole forming method one：Machining center (or bore
Bed) drilling → shutdown, the thick fraising → shutdown of back taper roughing reamer → machining center (or drilling machine) is manually loaded onto, it is thick manually to unload back taper
Reamer manually loads onto back taper bottoming reamer → machining center (or drilling machine) and finish reams hole → shutdown, manually unloads back taper bottoming reamer → cone
Hole quality inspection.This method fixture is simple, selects general back taper reamer, can both be realized in common driller, also can in processing
The matching processing of the heart (BT50 models) main shaft knife handle.But shortcoming is：Manually handling reamer, labor strength is big, low production efficiency,
The high processing costs such as cutter, taper hole quality is unstable, and processing rejection rate is 1%~5%.
Traditional back taper hole forming method two：Using special taper hole boring lathe, realize that conic boring adds using movement composition principle
Work realizes that cutter oblique movement and rotary cutting move with double-deck main axle structure, is rotated by motor gear and boring cutter is driven to revolve
Transhipment is dynamic；Special boring cutter bar is assembled with boring template cooperation, by hydraulic jack push rod boring cutter bar is promoted to do diagonal movement along boring template, real
Existing cone hole machine；After the completion of cone hole machine, feed cylinder counter motion is, it can be achieved that automatic withdrawal；By adjusting boring template angle and
Boring cutter direction, it can be achieved that just, reverse taper holes or straight hole processing, taper hole angle stabilization is high suitable for taper hole surface finish requirements
Commercial car knuckle product is processed.But：The drilling of this scheme disperses with bore hole process, and multiple clamping does not apply to machining center etc.
Numerically controlled automatic is processed, and taper hole positional precision is low；Bore surface precision is less than fraising precision；Separately limited by boring bar size, it is uncomfortable
With small-bore cone hole machine, it is clear that the requirement of the passenger cars knuckle such as SUV technical standard cannot be met；It needs to put into Special borer simultaneously
Bed, processing cost increase.
