Description

transmission

The invention relates to a transmission device, especially a transmission device with a protective structure.

Electrochemical processing is a processing method that uses the principle of electrochemical anode dissolution to remove materials, and belongs to the field of non-traditional processing. Electrochemical processing has the advantages of high processing efficiency, good surface quality, no electrode loss, and wide processing range. With the in-depth study of electrochemical processing technology, the application of this technology is becoming more and more extensive, especially for difficult-to-process materials and thin Wall structure components, such as aerospace titanium processing.

Since the electrochemical processing requires the electrolyte as the processing medium, the electrolyte is usually a neutral salt aqueous solution, which is easy to cause corrosion or damage to the processing equipment. Therefore, the special zero-group components of the processing equipment often need to be specially considered to prevent corrosion. For example, the area of the transmission mechanism needs to be strengthened to prevent corrosion, etc. In addition, when processing thin plate-shaped workpieces, the workpiece displacement during clamping and transportation must be considered. The question of accuracy. Generally speaking, when processing thin plate-shaped workpieces (such as material belts), it is necessary to form a hole in the material belt, and then use the hole in the material belt for positioning. However, this method requires an increase in processing time and processing equipment, which also causes the disadvantage of lengthy processing time.

The displacement sensing rod 21 is disposed in the third protection kit 25, so that the displacement sensing rod 21 is equivalent to the second seat body 112 disposed on the base 11, in addition, the displacement sensing rod 21 is located in the second through hole 170 and the third passage The hole 250, that is, the second protection kit 17 and the third protection kit 25 are looped around the displacement sensing rod 21. Since the second through hole 170 communicates with the third through hole 250, a closed accommodating space 100 is formed to protect the displacement sensing rod 21 and the position detector 23. In addition, the axis of the first protection kit 15, the axis of the second protection kit 17 and the axis of the third protection kit 25 are opposite to each other, namely the first protection kit 15, the second protection kit 17 and the third protection kit 25 Set for coaxial mode.

The moving unit 133 drives the second protection kit 17 to move, and the second protection kit 17 drives the position detector 23 to move. The position detector 23 moves along the displacement sensing rod 21, so that the position detector 23 and the displacement-sensing side unit 21 can sense the amount of displacement through magnetic induction, etc., and then can send a sensing signal to an external control device ( (Not shown), for the control device to know the displacement of the mobile unit 133 and control the driving unit 131.

Following the above, when the second protection kit 17 moves outward, the second protection kit 17 does not completely disengage from the first protection kit 15, so the accommodating space 100 inside the first protection kit 15 and the second protection kit 17 remains Closed. In this way, it can effectively invade the transmission module 13 by dust, liquid or any substance, and can reliably protect the driving unit 131 and the moving unit 133.
