關(guān)于焊接夾具中的定位器的介紹!

定位器在焊接生產(chǎn)中經(jīng)常使用的定位器有擋鐵、定位銷、V字鐵和樣板等。定位銷和樣板可以獨(dú)立使用,擋鐵和V字鐵通常安裝在焊接夾具的支承件上使用。安裝在夾具上的定位器除起定位作用外,還要和夾緊器配合起來承受各種力,如夾緊力、焊接變形引起的約東力等。

Positioners are often used in welding production, such as retaining iron, locating pin, V-shaped iron and template. The locating pin and template can be used independently. The retaining iron and V-iron are usually installed on the support of the welding fixture. The positioner installed on the fixture not only plays the role of positioning, but also cooperates with the clamp to bear various forces, such as clamping force, yodong force caused by welding deformation, etc.
一、擋鐵
1、 Retaining iron
擋鐵是應(yīng)用普遍,結(jié)構(gòu)簡單的一種定位器。固定擋鐵按定位原理直接把它們焊到鋼制的支承件上??刹饟蹊F直接插入支承件的錐孔上,不用時可以拔除。為了便于工件的裝上和卸下還有一種就是可退出的擋鐵。
Retaining iron is a positioner with common application and simple structure. The fixed retaining iron is directly welded to the steel support according to the positioning principle. The detachable retaining iron is directly inserted into the conical hole of the support and can be pulled out when not in use. In order to facilitate the loading and unloading of workpieces, there is also a retractable retaining iron.
二、定位銷
2、 Locating pin
它是靠圓柱面與工件的定位基準(zhǔn)孔接觸進(jìn)行定位的。在焊接生產(chǎn)中,工件度不大,多用短定位銷。位銷除固定在夾具上使用的以外,還有設(shè)計成可拆的。
It is positioned by the contact between the cylindrical surface and the positioning reference hole of the workpiece. In welding production, short locating pins are often used because the degree of workpiece is not large. In addition to being fixed on the fixture, the positioning pin is also designed to be detachable.
三、Ⅴ字鐵
3、 V-shaped iron
直徑較小的圓柱工件,如棒和鋼管進(jìn)行對接時,常使用ⅴ字鐵定位。ⅴ字鐵的槽口的其余尺寸決定于工件的直徑D。一般h=0.8D
V-shaped iron is often used to locate cylindrical workpieces with small diameter, such as rod and steel pipe. The remaining dimensions of the notch of V-shaped iron depend on the diameter D of the workpiece. General H = 0.8d
H-h=0.2D,當(dāng)Φ=90時,C=1.41D-2(H-h)。
H-H = 0.2d, when Φ= At 90, C = 1.41d-2 (H-H).
四、樣板
4、 Template
預(yù)先按各零件的相互位置制作樣板,裝配訃使它和工件緊靠進(jìn)行定位。
Make a template according to the mutual position of each part in advance, and assemble it to make it close to the workpiece for positioning.
