Description
Technical Field
The utility model relates to an automobile parts installs technical field, and specific saying is a motor gear hub dismounting device.
Background
The motor and the gear hub are assembled on an actual production line, the conditions of overlarge or undersize assembling force can occur, the conditions can cause the scrapping of the whole motor and the gear hub, and the scrapping cost is very huge. Therefore, a dismounting device is urgently needed to separate the gear hub from the motor, and the motor is recycled for the second time under the condition of not damaging the motor.
The existing dismounting device adopts a grappling hook mode or a lever mode, mainly aims at the condition that the press-fitting clearance between a motor and a gear hub is larger, but when the condition that the press-fitting clearance is small or the surface is completely contacted with the surface is met, the lever or the grappling hook can not extend into the clearance, so that the gear hub can not be dismounted, and the current dismounting mechanism can slightly and carelessly collide with a bearing at the upper end of the motor, thereby influencing the normal operation of the motor and increasing the product rejection rate cost.
Therefore, the gear hub dismounting mechanism which is suitable for the motor and the gear hub with small press-fitting clearance or complete surface-to-surface contact is necessary.
Disclosure of Invention
The utility model discloses broken through prior art's a difficult problem, designed one kind and can be applicable to motor and little or face of tooth hub pressure equipment clearance and the tooth hub disassembly body of face complete contact.
In order to achieve the purpose, the utility model discloses a motor tooth hub dismounting device, including block, ejecting nut, handle, clamping nut, clamping jaw, its characterized in that: the cap is fixed above the ejection nut by a fixing bolt, the ejection nut is fixed at the outer edge of the top of the compression nut by a threaded connection mode, a clamping nut is arranged below the ejection nut, the clamping nut is also fixed at the outer edge of the middle part of the compression nut by a threaded connection mode, the clamping nut is fixed with a pressing block by a bolt, the pressing block is fixed on a clamping sleeve, so that the clamping nut, the pressing block and the clamping sleeve are integrated into an assembly, the clamping sleeve is sleeved at the outer edge of the bottom end of the compression nut, a clamping jaw connecting piece is fixed at the bottom end of the compression nut, the middle part of a clamping jaw is fixed on the clamping jaw connecting piece by a cylindrical positioning pin, the top of the clamping jaw is fixed on the clamping jaw connecting piece by an O-shaped ring, an ejection shaft is embedded in the middle of the compression nut, the top of the ejection, the bottom of the clamping sleeve is also embedded with a steel ball, a first handle is fixed on the ejection nut, and a second handle is fixed on the clamping nut.
The ejection shaft and the compression nut are in clearance fit.
The embedded position and angle of the steel ball correspond to those of the clamping jaw.
Compared with the prior art, the utility model, can easily take out the tooth hub and not have the damage risk to the motor bearing when dismantling the tooth hub, owing to need not insert the gap with lever or clamping jaw, consequently also can easily take out the little or gapless motor tooth hub in clearance.
