Controlled electro-pneumatic power tools and interactive consumable

A controlled electro-pneumatic power tool includes an electro-mechanical adjustable valve, a pneumatic motor and a rotational speed sensor connected to a microcontroller for the selection, monitoring and adjustement of the rotational speed in real time. The electro-pneumatic power tool may include input buttons, data ports to save data and a communication port to read / write data from an interactive consumable. The electo-pneumatic power tool may also include a battery and a generator as well as a variable speed transmission with flexible shaft and lightweight handpiece. Using the communication port, important data for the consumable, such as optimum rotation speed, optimum applied pressure and average usage time, can be transmitted to the controlled electro-pneumatic power tool. The controlled electro-pneumatic power tool can read and utilise the transmitted data to select, adjust and maintain the optimum process parameters for the consumable without any input from the operator person. Furthermore, the communicated data can be used to warn the operator person that the tool used is inadequate for the selected consumable, to caution the operator person if he is using the consumable inadequately and to advise him when the consumable should be replaced for safe operation. This will increase the safety of the operator person, improve the quality of the work performed with pneumatic power tools and limit potential damages to the parts being treated.

Automobile gear end surface polishing device

The invention provides an automobile gear end surface polishing device, and relates to the technical field of automobile gear polishing. The automobile gear end surface polishing device comprises a working table, standing columns are fixedly installed on both sides of the top of the working table, and motor mounting blocks are fixedly installed on both sides of the inner wall of each standing column. According to the automobile gear end surface polishing device, through arrangement of telescopic motors, threaded rods, telescopic blocks, sliding rods, a strip-shaped sliding groove and a cross plate, a polishing device body on the bottom of the cross plate can vertically move between the two standing columns under driving of the telescopic motors; through arrangement of the cross plate, the sliding groove and supports, the polishing device body on the bottom of the cross plate can transversely move on the bottom of the cross plate; through arrangement of a polishing table, a rotating rod and a clamping base, a gear to be polished which is fixed to the top of the clamping base in a clamped mode can conduct circular motion on the bottom of a polishing motor under driving of the rotating rod. In sum, by means of the automobile gear end surface polishing device, the effect that adjustment is convenient is achieved, it is convenient for people to polish the end surface of the gear from different angles, and the quality of the gear after polished is better.
