The cylindrical grinder is mainly composed of a bed body, a headstock device set on the bed body, and a grinding device. The headstock device is used for installing and clamping workpieces and driving them to rotate. The grinding device is equipped with a grinding wheel, which is used for grinding the workpiece.
1. Adjustment of hydraulic transmission part of workbench:
Press the start button of the hydraulic pump, then place the hydraulic on/off knob of the worktable in the "on" position, and then skip the position of the reciprocating stop iron of the worktable, so that the worktable can enter the working stroke and the stroke valve is pressed down by the stroke pressure plate; Adjust the grinding speed knob of the worktable to make the worktable move back and forth; After the movement of the cylindrical grinder worktable is completed, lift the phase change handle by hand to pass over the right shift iron; At this point, the travel pressure plate leaves the travel valve, and the worktable switches to fast travel; The middle stop pressure plate presses down the travel valve to stop the movement of the worktable.
2. Adjustment of the transverse feed mechanism of the grinding wheel
Grinding wheel heading feed break adjustment and automatic adjustment; The feed is achieved by hand cranked wheels, and can be fine tuned by pressing the action handle. The feed rate is 0.005mm per grid; When the automatic feed knob is turned to the "on" position, the grinding wheel will perform periodic automatic feed, and adjusting the top rod can control the feed amount.
3. Adjustment of Wheel Corrector
Start the hydraulic pump and turn the action selection knob to the dressing position. At this time, the grinding wheel corrector automatically falls down, the positioning pin contacts the support screw, and the diamond enters the dressing position state. During the trimming process, it is necessary to adjust the position of the trimming stopper and the trimming speed knob of the external cylindrical grinder worktable. After the trimming is completed, the action selection knob can be rotated to return the rotary head to its original position under the action of the spring.
