我厂生产的层板结构高压容器,在生产过程中,需要将其纵向焊缝磨平。过去我们使用风铲批,这样劳动强度大,效率低。后来,我们应用无齿锯,把一部废旧车床导轨改装成一台“自动纵向焊缝磨平机”,基本实现磨焊缝机械化,大大减轻劳动强度,提高效率一倍左右。这台设备外形及其传动示意分别见图1和图2。其工作原理为:当减速电机2转动时,带动链轮3及4,由于它们齿数相同,故此链轮4转速为31转/分;再带动偏心轮6,偏心轮又带动曲柄连杆7及滑块9作往复运动,速度为每分钟往复31次,其行程可通过调节连杆与偏心轮的连接位置A来改变,亦即由此可调节 I plant the production of laminated high-pressure container, in the production process, the vertical weld needs to be polished. In the past we used wind shovel batch, so labor-intensive, inefficient. Later, we applied a toothless saw to convert a worn-out lathe guide rail into a “Automatic Longitudinal Weld Mill” to basically mechanize weld wear, greatly reducing labor intensity and doubling the efficiency. The appearance of the device and its transmission diagram shown in Figure 1 and Figure 2. Its working principle is as follows: When the geared motor 2 rotates, the sprockets 3 and 4 are driven. Due to the same number of teeth, the speed of the sprocket 4 is 31 rev / min. Then, the eccentric 6 is driven to move the crank 7 and The slider 9 reciprocates at a speed of 31 reciprocations per minute, the stroke of which can be changed by adjusting the connection position A of the connecting rod with the eccentric, that is, thereby adjustable
