The invention discloses a lead screw rust removal tool, and belongs to the field of lead screw maintenance. The lead screw rust removal tool comprises a driving mechanism, a rotating mechanism and a plurality of grinding mechanisms. Each grinding mechanism comprises a fixing section, an elastic piece and a grinding piece. The driving mechanism is detachably connected with the first end of the rotating mechanism, and the multiple grinding mechanisms are spirally fixed to an inner cavity of the rotating mechanism. The first ends of the fixing sections are fixedly connected with the inner wall ofthe rotating mechanism, the second ends of the fixing sections are connected with the first ends of the elastic pieces, and the second ends of the elastic pieces are fixedly connected with the grinding pieces. According to the lead screw rust removal tool, when the driving mechanism drives the rotating mechanism to rotate relative to a to-be-ground lead screw after the first end of the to-be-ground lead screw is sleeved with the second end of the rotating mechanism, as each grinding mechanism comprises the corresponding elastic piece and the corresponding grinding piece, the grinding mechanisms can elastically deform under the action of external force, then the grinding pieces extend into a threaded groove in the to-be-ground lead screw to grind the threaded groove, and the thoroughness of rust removal of the to-be-ground lead screw is guaranteed.
Description
technical field [0001] The application relates to the field of lead screw maintenance, in particular to a lead screw derusting tool. Background technique [0002] Valves are an integral part of a variety of conveying processes. The valve must be flexible and easy to use, so that the valve can be switched on and off quickly to realize the conduction or shutdown of the conveying process. However, during the use of the valve, it is easily affected by the environment and the transmission medium, causing the screw of the valve to rust, which in turn makes it difficult to open and close the valve. In severe cases, the valve cannot be opened or closed. The delay delays the turn-on or turn-off of the conveying process. Contents of the invention [0003] The application provides a lead screw derusting tool, which can solve the problem of low grinding efficiency of the lead screw. Described technical scheme is as follows: [0004] The present application provides a lead screw de...
