Description

Novel thimble type motor fan disassembling puller Technical Field The utility model relates to the technical field of disassembling puller, in particular to a novel thimble type motor fan disassembling puller. Background The motor fan is usually made of engineering plastics or aluminum alloy materials, and the motor is often placed in an open air environment and runs for a long time, so that the fan is easy to damage and deform, the shaft end of the motor can be rusted, and the difficulty of dismantling the fan is increased. Numerous attempts have been made by the skilled person to solve such problems. For example, the centrifugal pump impeller dismounting device disclosed in Chinese patent CN213290092U can enable the peripheral stress to be uniform when the impeller is dismounted by uniformly adjusting the adjusting piece, so that the strain of the impeller is avoided. However, the existing solutions still have drawbacks. Because of the structural difference of the motor fans, some have machining holes and other have no machining holes. For fans with processing holes, the existing puller has the problems of improper installation position, too small processing holes, difficult installation and the like, and for fans without processing holes, the existing puller cannot be used and can only be dismantled by means of a screw driver or a crowbar, so that the motor fan is greatly damaged. Disclosure of utility model The utility model aims to solve the technical problems of overcoming the defects in the prior art and providing a novel ejector pin type motor fan dismounting puller. The technical scheme adopted by the utility model is as follows: The utility model provides a novel thimble type motor fan dismantles and draws horse, including cup jointing the fan on motor rotor, be provided with on the fan and dismantle and draw the horse, dismantle and draw the horse including frame body, locking prevent that the thrust mechanism is twisted soon, wherein: The frame body is in a two-claw/three-claw hook-shaped arrangement with central symmetry and comprises two layers of claw seats which are arranged in parallel and a claw frame which is positioned between the claw seats, and the outer edge of the claw seat is provided with a strip hole which is used for adjusting the distance between the claw frame and the claw frame; The locking tension preventing mechanism comprises tension preventing jackscrews positioned at the outer sides of the claw seats and claw jackscrews positioned at the tail ends of the claw frames, wherein the tension preventing jackscrews penetrate through the strip holes and are abutted against the claw frames, and the claw jackscrews vertically abut against the outer end parts of the fans; The screwing thrust mechanism comprises a thrust screw rod, wherein the thrust screw rod sequentially penetrates through the two layers of claw seats and props against the center of the motor rotor, and the fan is dismounted in the opposite direction relative to the motor rotor by screwing the thrust screw rod. According to the technical scheme, the outer end part of the fan is pre-fixed by disassembling the pull Ma Dingru, and then the motor rotor is applied with reverse acting force by utilizing a thrust screw rod for disassembling the pull once, so that the fan is disassembled in the opposite direction relative to the motor rotor. The frame body is used for providing support, the locking tension preventing mechanism and the screwing thrust mechanism are arranged on the frame body, the locking tension preventing mechanism is used for locking the fan and adjusting the distance between the locking tension preventing mechanism and the outer end part of the fan, so that the frame body is fixed more tightly, the screwing thrust mechanism is used for adjusting the distance between the fixing frame and the electronic rotor, the reverse dismantling force of the fan relative to the motor rotor is indirectly provided, and the safety and the working efficiency in the operation process are improved on the premise that the motor fan is not damaged in the dismantling process. In addition, the novel ejector pin type motor fan disassembling puller provided by the utility model can also have the following additional technical characteristics: According to one embodiment of the utility model, the connection parts of the thrust screw rod and the knuckle seat are welded with reinforcing rings. In the technical scheme, the reinforcing rings are positioned at the center of the hook claw seat and used for increasing the overall strength of the novel puller.
