Detailed Description
The invention is further described below with reference to the accompanying drawings.
A dismouting frock for fixed interior magnetic steel of ripple spring, as shown in fig. 1, 2, includes: the sleeve comprises a sleeve 1, a locking sleeve 2, a ring sleeve 3 and a fixing ring 4. The sleeve 1 is a hollow cylinder, one end of the sleeve is provided with external threads, and the other end of the sleeve is provided with a raised step; the locking sleeve 2 is a circular ring with an L-shaped section, the locking sleeve 2 is provided with an internal thread, the external thread at the end part of the sleeve 1 is matched with the internal thread of the locking sleeve 2, and the locking sleeve 2 is screwed at the end part of the sleeve 1 through the thread; the ring sleeves 3 are two semicircular rings provided with grooves, the shapes of the grooves are matched with the steps protruding from the sleeve 1, and the grooves of the two ring sleeves 3 are clamped on the steps of the sleeve 1 to form a complete circular ring; the fixing ring 4 is a circular ring with an L-shaped section, the circular ring is sleeved on the sleeve 1, the diameter of an inner hole of the end face is matched with the outer diameter of the sleeve 1, the inner diameter of the circular ring is matched with the outer diameter of the ring sleeve 3, and the ring sleeve 3 is fixed.
The workpiece comprises an upper main shaft 5, an inner magnetic steel assembly 6, a corrugated spring 7, a steel wire retainer gasket 8 and a steel wire retainer 9, as shown in figures 3 to 6.
When the device is used, the sleeve 1 is sleeved on a workpiece, the end face of one side of the step of the sleeve 1 is aligned with the end face of the inner magnetic steel component 6, the two ring sleeves 3 are clamped on the step of the sleeve 1, the inner diameters of two surfaces of the groove of each ring sleeve 3 are different, the inner diameter of one surface close to the fixing ring 4 is matched with the outer diameter of the sleeve 1, the inner diameter of the other surface is matched with the outer diameter of the upper spindle 5, the end face of the inner magnetic steel component 6 is clamped, the fixing ring 4 is sleeved on the ring sleeve 3, and the ring sleeves 3 are fixed; the terminal surface of lock sleeve 2 blocks steel wire retaining ring gasket 8, and rotatory lock sleeve 2 of screwing up compresses tightly ripple spring 7 through steel wire retaining ring gasket 8, spills the retainer groove on main shaft 5, at retainer inslot installation steel wire retaining ring 9, and the installation is accomplished the back, and rotatory release lock sleeve 2, ripple spring 7 resume normal position, take off solid fixed ring 4, pull down two ring covers 3, take off all frocks, accomplish all assembly work.
