椭圆磨床是内燃机活塞加工的重要设备,在无专用设备情况下,我们试制了磨椭圆装置,在M1431外圆磨床上加工出了合格的椭圆曲线,并保持机床原有结构,卸卞附件仍可进行普通内外圆加工。工作原理利用头架主轴和拨盘能分别转动的特点,在主轴锥孔内装上偏心轴24(图1)椭圆凸轮1装于拨盘上。一方面拨块2带动传动套3使工件转动;另一方面凸轮推动曲杆32,使轴30产生周期性摆动。摇臂21、29通过连杆
Elliptical grinder is an important equipment for internal combustion engine piston processing. In the absence of special equipment, we trialled the milling ellipse device, processed a qualified elliptical curve on the M1431 cylindrical grinding machine, and maintained the original structure of the machine tool. Ordinary inner and outer circle processing. Working principle The use of headstock spindle and dial can be rotated respectively, equipped with eccentric shaft in the spindle taper hole 24 (Figure 1) oval cam 1 mounted on the dial. On the one hand, the dial 2 drives the transmission sleeve 3 to rotate the work piece; on the other hand, the cam drives the curved rod 32 to make the shaft 30 oscillate periodically. The rocker arms 21, 29 pass through the connecting rod
