Abstract
The invention discloses the methods that a kind of pair of false boss stop compresses, housing screw is selected according to false boss position and size, process the step through-hole that angle α is formed with tooling plane respectively on false boss and tooling, the small end of two step through-holes is connected to the housing screw hole to be formed for installing housing screw；Screw is installed and tightened in housing screw hole, so that tooling is adjacent to part.The beneficial effects of the present invention are: false boss rotates during the present invention can be effectively prevented part by numerical control processing removal false boss, it can also be used to which the fixation of big surplus improves the reliability of compression, prevents part from abrading.
Description
Technical field
The present invention relates to Computerized Numerical Control processing technology fields, are the methods that a kind of pair of false boss stop compresses specifically.
Background technique
With the improvement of continuing to optimize of modern designs means and processing method, all kinds of parts gradually to enlargement, complicate,
Integration direction is developed, process-cycle shortened, and the requirement to processing quality also steps up.For the processing effect for improving part
Rate, at this stage, aluminium alloy, titanium alloy, stainless steel-like parts mostly use the mode of numerical control processing to be processed, and outer on part
False boss is added part to be fixed and centering.As part process boss quantity is stepped up, for the processing for improving part
Efficiency usually requires that part just removes most false boss in NC Machining Process.
False boss is connect by screw with tooling and retaining element, and current methods set screw axis to and tooling table
Face vertical direction, when removing false boss using numerical control processing mode, false boss is gradually separated with part, in the work of cutting force
Under, when completely cutting through, if the pressing force applied on false boss is insufficient, false boss is rotated, will directly be weighed wounded even
Scratch part.It needs additionally to increase process and cost using pin mode is increased, in addition, can by way of increasing packing washer
False boss displacement is reduced to a certain extent, but not in place when installing, when nut center and excessive pitch deviation can still lead
Cause pressing force insufficient, false boss rotates the appearance of problem.
Summary of the invention
The purpose of the present invention is to provide the methods that a kind of pair of false boss stop compresses, and can be effectively prevented number of components
False boss rotates during control processing removal false boss, it can also be used to which the fixation of big surplus, that improves compression can
By property, prevent part from abrading.
The present invention is achieved through the following technical solutions:
The method that a kind of pair of false boss stop compresses selects housing screw according to false boss position and size, convex in technique
The step through-hole that angle α is formed with tooling plane, the small end connection of two step through-holes are processed on platform and tooling respectively
Form the housing screw hole for installing housing screw；Screw is installed and tightened in housing screw hole so that tooling with
Part is adjacent to.
Further, in order to preferably realize the present invention, specifically includes the following steps:
Step S1: incision end when removing according to the design feature of false boss and tooling, false boss and cutting out the position at end,
It determines screw inclined direction, sets the inclination angle alpha of screw, calculate corresponding screw length L；
Step S2: the axis in housing screw hole is determined according to false boss bottom plane profile and screw tilt angle；
Step S3: width and processing stability according to false boss require to choose appropriate screw diameter specification, determine nut
With the specific size of screw rod；
