Description
本創作為有關十字孔固定軛，尤其關於十字孔固定軛的製造技術。This creation is related to the manufacturing technology of the cross hole fixing yoke, especially regarding the cross hole fixing yoke.
請參閱「圖1」所示，十字孔固定軛1(end yoke)，為汽車傳動軸承的重要零件，十字孔固定軛1的結構包含一傳動套筒2以及一與該傳動套筒2的軸向垂直的連接軛3，該連接軛3具有中心軸線位於同一線上且為開放狀的一第一半圓軛孔4與一第二半圓軛孔5，該第一半圓軛孔4與該第二半圓軛孔5分別具有一圓弧部6，而該傳動套筒2設置一內齒輪。Referring to Figure 1, the cross yoke 1 is an important part of the automotive transmission bearing. The structure of the cross hole fixing yoke 1 includes a transmission sleeve 2 and an axis with the transmission sleeve 2. To the vertical connecting yoke 3, the connecting yoke 3 has a first semi-circular yoke hole 4 and a second semi-circular yoke hole 5 which are open on the same line, and the first semi-circular yoke hole 4 and the second semicircle The yoke holes 5 each have a circular arc portion 6, and the transmission sleeve 2 is provided with an internal gear.
請再一併參閱「圖2」所示，該十字孔固定軛1通常為兩兩為一組，並搭配一十字圓柱7使用，該十字圓柱7具有四柱體8，該四柱體8為兩兩相互垂直設置，並該四柱體8分別套入該十字孔固定軛1的該第一半圓軛孔4與該第二半圓軛孔5，讓該二十字孔固定軛1組接在一起，而形成可萬向轉動的傳動結構。Please refer to FIG. 2 again. The cross-hole fixing yoke 1 is usually a pair of two and is used together with a cross cylinder 7 having a four-column 8 which is two-two. The four-cylinders 8 are respectively placed in the first semi-circular yoke hole 4 and the second semi-circular yoke hole 5 of the cross-hole fixing yoke 1 so that the two cross-hole fixing yokes 1 are assembled together to form Universally rotating transmission structure.
習知製造該十字孔固定軛1的方式，為先利用鑄造(或其他機械加工亦可)的方式，製造出該十字孔固定軛1的粗胚，接著利用二次加工的方式，再次加工該第一半圓軛孔4與該第二半圓軛孔5的圓弧部6，其目的在於讓該第一半圓軛孔4與該第二半圓軛孔5的圓弧部6的中心軸線位於同一線上，最後再加工形成其他細部結構。其中圓弧部6的中心軸線其同心度誤差必須滿足需求，更精確地說，必須讓其誤差在正負2條(10微米)之內，否則即視為不良品，必須加以剔除。Conventionally, the method of manufacturing the cross hole fixing yoke 1 is to first manufacture a rough blank of the cross hole fixing yoke 1 by means of casting (or other machining), and then re-machining the method by means of secondary processing.

而為了達到精度上的要求，傳統該十字孔固定軛1的製造方式，一般為使用CNC精密加工的方式處理，以藉由CNC精密加工的高精密度特性，讓該第一半圓軛孔4與該第二半圓軛孔5的圓弧部6的中心軸線差異滿足精度上要求。然而CNC精密加工的加工速度緩慢，且機台的維護成本高昂，其會墊高該滑動軛的製造成本，換句話說，該十字孔固定軛1的製造成本居高不下，無法滿足降低製造成本的需求。In order to meet the precision requirements, the conventional method for manufacturing the cross-hole fixing yoke 1 is generally processed by CNC precision machining, so that the first semi-circular yoke hole 4 is made by the high precision characteristic of CNC precision machining. The difference in the central axis of the circular arc portion 6 of the second semi-circular yoke hole 5 satisfies the accuracy requirement. However, the machining speed of CNC precision machining is slow, and the maintenance cost of the machine is high, which will increase the manufacturing cost of the sliding yoke. In other words, the manufacturing cost of the fixed-hole fixing yoke 1 is high, and the manufacturing cost cannot be reduced. Demand.
