The invention relates to a rapid locking mechanism for a stirring paddle. The rapid locking mechanism for the stirring paddle comprises a stirring shaft, the stirring paddle, a pressure sleeve, an adhesive tape retaining sleeve, adhesive tapes and two cams, wherein the stirring shaft is arranged in the stirring paddle; a drive pin arranged on the stirring shaft is located in a groove arranged on the stirring paddle; the pressure sleeve is sheathed onto the stirring shaft; the adhesive tape retaining sleeve is sheathed onto the pressure sleeve; the adhesive tapes are arranged between the pressure sleeve and the adhesive tape retaining sleeve; the upper ends and the lower ends of the adhesive tapes are respectively contacted with the top end of the adhesive tape retaining sleeve and the bottom end of the pressure sleeve; the two cams are respectively arranged at both sides of the stirring shaft through a cam pin shaft; and when in a locking state, the bottom end of the adhesive tape retaining sleeve is compressed tightly by the surface at the maximum diameter position of each cam; the adhesive tape retaining sleeve and the pressure sleeve are respectively supported by the upper ends and the lower ends of the adhesive tapes; and the upper end face of the stirring paddle is compressed tightly by the bottom end face of the pressure sleeve. According to the rapid locking mechanism for the stirring paddle, any parts do not need to be disassembled or assembled during the process of installing and disassembling the stirring paddle and the stirring shaft, thus, the stirring paddle and the stirring shaft are rapidly connected and are effectively locked; the stirring paddle replacement time and the stop time of equipment are shortened; and the utilization ratio of a machine is greatly increased.

Disclosed is a disc-type magnetically connected chemical sliding vane pump, which is used for conveying various oils and chemical media. It includes motor, connection plate, disc-type external magnetic rotor, pump body with eccentric inner cavity, internal magnetic rotor with groove, pump shaft, sliding plate, circular magnet, sliding bearing, hard alloy moving ring, silicon carbide static ring, Round nut, pump back cover. The inner magnetic rotor of the present invention is integrated with the slotted rotor of the sliding vane pump to become an inner magnetic rotor with slots. Due to the change of the magnet installation method embedded in the outer magnetic rotor and the inner magnetic rotor with slots, the ring magnetic connection structure is changed to The disc-type magnetic connection structure directly uses the thin wall on the side of the pump body to isolate the outer magnetic rotor and the inner magnetic rotor with grooves, which cancels the isolation sleeve necessary for the previous ring-type magnetic pump, shortens the length of the pump body, and makes the structure simpler and more compact. The maintenance efficiency is greatly improved, the skill requirements for maintenance personnel are reduced, and the high efficiency and energy saving of the pump are realized.

The invention discloses an automatic welding system for a welding rod and an automatic welding method. The automatic welding system comprises a welding power source, the welding rod and a work piece, and also comprises a human-computer interaction interface, an electric arc information acquisition system, a motion executing mechanism and a welding power source control module, wherein the human-computer interaction interface is used for setting parameters and displaying data; the electric arc information acquisition system is used for acquiring the data of welding voltage and welding current between the welding rod and the work piece in real time; the motion executing mechanism is used for driving the welding rod to move according to the information acquired by the electric arc information acquisition system and regulating the speed in real time according to a specific control strategy so as to regulate the voltage of the electric arc; the welding power source control module is used for connecting or disconnecting the welding power source according to the information acquired in real time by the electric arc information acquisition system. The automatic welding system disclosed by the invention is simple to clamp; periodic regulation is not needed; the processing is reasonable; the voltage fluctuation range of the electric arc is small during welding; automatic arc striking can be realized; the inclination angle of the welding rod can be regulated; the conveying speed of the welding rod can be automatically regulated; power is automatically cut off after welding is ended.

The invention relates to an oil storage device of a high-pressure motor bearing, which is mainly used for improving the protection grade of the high-pressure motor bearing, such as the functions of dust prevention and water prevention. An oil throwing disk is fixed on a rotating shaft of a motor, a V-shaped ring is put in the outer end of an inner ring of a left cover of the bearing to improve the protection grade, and the inner side of a bearing set is fixed through a right cover of the bearing. The oil storage device is characterized in that labyrinth parts are arranged on an inner cover and an outer cover of the bearing, and the left cover of the bearing is internally and additionally provided with the inner ring. The oil storage device has simple, compact and reasonable structure and obvious effect. Under the condition of not changing structure materials, the protection grade of the motor is effectively improved through additionally arranging a labyrinth ring and the labyrinth parts on the inner cover and the outer cover of the bearing and the oil throwing disk. The inner ring is additionally arranged in the left cover of the bearing, and lubricating oil is thrown into an oil storage cavity in the inner ring and the bearing due to the action of centrifugal force, thus the oil storage capacity is greatly enhanced. For part processing, the oil storage device is simple and reasonable and has no influence on mechanical property of workpieces, and for mechanical deviation, because a single radial edge is preserved with an allowance of 1mm and a single axial edge is preserved with an allowance of 2mm, the assembly of the parts have no problems.
