Description
Technical field
The present invention relates to auto parts and components processing equipment field more particularly to a kind of Chamfer Curve mechanisms of throttle plate pin.
Background technique
Throttle plate pin is used in a kind of part in automotive engine control mechanism, and material is that 304 stainless steels and 420F are easy
Steel is cut, good toughness intensity is high, and effect is the valve shaft for controlling valve capacity size.The processing essence on throttle plate pin surface
Spend more demanding, the processing of the elongated slot especially on electronic throttle valve spindle.Existing throttle plate pin diameter has 8mm and 10mm respectively
Two kinds of specifications, length have 30 plurality of specifications of 84.3mm to 137.2mm, and there are 60 ° of centre bores at both ends, have on axis screw hole, thread,
Annular groove etc. is all provided with one long flat slot among every axis, symmetrically opens and wear from central axes two sides, and groove width has 1.15mm to 2.08mm,
Length has 38.3 to 62.5 specifications to differ, and slot both ends are crescent moon curved shape.
Currently, after having carried out the processing of elongated slot for throttle plate pin, can under the margin residual of elongated slot burr, then lead to again
The finishing that deburring operation carries out surface is crossed, burr is not allow for.Existing chamfering burr removing method is: manually enterprising in grinding wheel
Row polishing, low efficiency and grind come product it is inconsistent, unstable quality.As Authorization Notice No. is " CN201439134U "
Disclose a kind of for processing the milling cutter of elongated slot of electronic choker shaft in Chinese utility model patent, scheme is in standard milling cutter
It is respectively arranged with deburring blade and deburring blade on one at the top and bottom of cutter blade, is added in the elongated slot of electronic throttle valve spindle
While work, upper deburring blade and deburring blade can carry out deburring, such electronics to the burr of long groove edge
Elongated slot processing on throttle plate pin carries out simultaneously with deburring, the process that independent deburring is omitted.But nonetheless, should
Milling cutter is also to need man-hour manually hand-held deburring, therefore it is low to remain processing efficiency, the problem of taking time and effort.It ground again later
Numerical control wheel sander and numerical control countersink beveler are issued, as a result, low efficiency is not satisfactory.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of Chamfer Curve mechanism of throttle plate pin, the sections
