图1所示的弹性管联轴节,多用于传递力矩小于50g·cm的传动系统中。这种弹性管联轴节,具有结构简单,装配方便,无空回误差,能吸收冲击、振动等特点。在电子工业产品中,设计师们大多喜欢采用。加工弹性管联轴节的关键工序尺寸是A、B和t,即螺旋槽的切削成形。我们根据铣削和车削两种加工工艺特点,吸取了它们的长处,在c616普通车床上成功地加工出了弹性管联轴节。在车床上加工弹性管联轴节,需要设计制造一副简易工装(见如图2)。其中α角等于联轴节螺旋升角,即tgα=t/(πd),螺杆的螺距等于联轴节的螺距t。这副简易工装固定在刀架上。
The flexible tube coupling shown in Fig. 1 is mostly used in transmission systems with a torque of less than 50 g · cm. This flexible tube coupling, with simple structure, easy assembly, no error back to the error, can absorb the impact, vibration and so on. In the electronics industry, designers mostly like to use. The key process dimensions for machining flexible tube couplings are A, B, and t, that is, the cutting of the helical flutes. According to the characteristics of both milling and turning machining, we draw on their strengths, the successful processing of flexible pipe coupling on the c616 ordinary lathe. In the lathe machining flexible tube coupling, the need to design and manufacture of a simple tooling (see Figure 2). Where α is equal to the joint helix angle, that is tgα = t / (πd), the pitch of the screw is equal to the pitch of the joint t. This pair of simple tooling is fixed on the tool holder.
