The observation window 85 is used for facilitating the observation of the processing state, and impurities generated by the processing are collected in a cloth bag (not shown in the figure) through the dust removing opening 86.
In the present invention, it is preferable that sleeve locking means for locking the sleeve be provided in both the left head stock 7 and the right head stock. Each time the wheel is fine-tuned, the handle must first be unscrewed and a gentle tap must be made to the rear side to disengage the locking sleeve arrangement. When a workpiece is ground, the device must be locked, and the workpiece grinding size instability caused by the position change of the grinding wheel in grinding is prevented.
In use, the cover can be opened after the machine tool is powered off for at least 5 minutes if the cover is to be removed or if the machine tool needs to be serviced. The standard prompt identification of the live line components is required to be implemented in the process of debugging or maintaining the machine at any time. When the machine tool is periodically cleaned or preventively maintained, the power supply and the air supply of the machine tool are disconnected, residual air is exhausted, and the machine tool can start to operate after waiting for at least 5 minutes. When the machine tool is unattended and not used for a long time, the power supply and the air source of the machine tool need to be disconnected. In an emergency situation, the user should press the emergency button to cut off the power supply and the air supply to stop the machine tool. When the emergency stop button is released, the emergency stop button is rotated to be opened according to the arrow direction.
The optimal working principle of the invention is as follows:
treat the machined part with a plurality of and treat that machined part 100 (friction disc) is placed in work piece silo 20, promote through work piece die clamping cylinder 21 afterwards and treat the machined part, drive right emery wheel and left emery wheel rotation respectively through right motor 9 and left motor 6, treat machined part 100 through work piece picture peg 19 pushes down, cause to push down to treat that machined part 100 falls to between left emery wheel and the right emery wheel from the pan feeding mouth, along with treating that machined part 100 falls and accomplish the grinding through rotatory right emery wheel and left emery wheel, through discharge gate 12 roll-off after the processing is accomplished, still can set up the collecting tray in connecing silo 62 department, be used for collecting the processing completion.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
