In conclusion, the bead separating operation is completed by the pressing plate 12 and the movable plate 14 together, in the process of pressing the pressing plate 12 downwards, part of the fixed rods 6 are driven to press part of the steel beads, then the pressing plate 12 drives the ejector rod 10 to correct the inner ring, then the pressing plate 12 drives the movable plate 14 to move downwards, and part of the fixed rods 6 are pressed downwards through the movable plate 14, so that the rest part of the steel beads are pressed, the bead separating operation and the inner ring correction operation are performed step by step, the relevance among all the components is small, the probability of failure can be effectively reduced, the later maintenance is more convenient, otherwise, as long as a place has a problem, the whole equipment needs to be disassembled and debugged.

The sliding seat 2 passes through slide rail and 1 horizontal sliding connection of mount table, the upper end of sliding seat 2 is equipped with domaticly, and the lower extreme of sliding seat 2 is equipped with spacing recess 17, the lower extreme of spacing recess 17 is equipped with the through-hole, the lower extreme of sliding seat 2 is equipped with end cap 18, and end cap 18 is from following up grafting in the through-hole, one side of spacing recess 17 is equipped with movable post 19, and movable post 19 pegs graft on sliding seat 2, movable post 19 passes through third spring and 2 elastic connection of sliding seat, and movable post 19's bottom offsets with end cap 18, end cap 18's top is equipped with a positioning groove 21, and end cap 18's upper end is equipped with the slot 22 that agrees with mutually with ejector pin 10.

In order to conveniently finish the bead separation work, an inclined movable seat 2 is arranged, the movable seat 2 can move, when the bead separation device is used, only the inner ring and the outer ring are required to be placed in the limiting groove 17 on the movable seat 2, the limiting groove 17 is slightly larger than the outer diameter of the outer ring, then beads are placed between the gap of the inner ring and the gap of the outer ring, because the movable seat 2 is obliquely placed, the beads are placed between the gap of the inner ring and the gap of the outer ring and then are converged at the lowest end of the limiting groove 17, which is also the place where the positioning groove 21 is located, under normal conditions, a bead can be just stopped in the positioning groove 21, if not, the movable seat 2 can be shaken at the moment, under the action of self inertia, the inner ring and the beads can move until the beads are uniformly distributed at the lower side of the limiting groove 17.

After the ball separation is finished, the retainer is required to be assembled, the retainer is required to be arranged in the bearing from the upper direction and the lower direction, in the traditional technology, the retainer is generally placed at the upper end of the bearing firstly, then the bearing is turned, and then the other retainer is placed in the bearing, the technical scheme is that a detachable plug 18 is arranged at the lower side of a movable seat 2, after the ball separation and correction operation of the bearing is finished, a movable column 19 is pressed downwards, the plug 18 can fall out from a through hole under the pushing of the movable column 19, the diameter of the through hole is slightly larger than that of the retainer, at the moment, because the steel ball is pressed by a fixed rod 6, the steel ball can play a fixed role on an inner ring, and even if the inner ring is in a suspended state, the through hole is communicated with a limiting groove 17, the retainer is placed into the bearing from the lower part of the bearing through the through hole, then, the lower retainer and the bearing are held by hands, the pressing plate 12 is loosened, then the fixed seat 4 is removed, the upper retainer is placed into the bearing from the upper part, and finally the two retainers are riveted together through a riveting machine, so that the assembly work of the bearing is completed.

It should be noted that: in order to place the lower retainer conveniently, a notch is arranged on the mounting table 1 and is positioned at the lower side of the movable seat 2.

Furthermore, the support arm 5 is L-shaped, and the bottom end of the support arm 5 is inserted into the support seat 3. Supporting seat 3 is hollow structure, and supporting seat 3 passes through screw and 5 fixed connection of support arm, the bottom of supporting seat 3 rotates with mount table 1 to be connected, like this when using, only need to rotate the position of the regulation fixing base 4 that supporting seat 3 just can be convenient, remove fixing base 4 during the assembly, make it can not obstruct the assembly, during the use, rotate supporting seat 3, make fixing base 4 remove the upper end of sliding seat 2, then press clamp plate 12 downwards, under the drive of clamp plate 12, can once only accomplish branch pearl of bearing and the work of rectifying of inner circle through dead lever 6 and ejector pin 10.

Kick-off lever 7 is by last body of rod 701, down body of rod 702 and stop collar 703 are constituteed, the one end of going up body of rod 701 runs through fixing base 4, and go up body of rod 701 through

second spring

24 and 4 elastic connection of fixing base, the one end and the last body of rod 701 fixed connection of lower body of rod 702, and the lower extreme of lower body of rod 702 is equipped with kicking block 704, kicking block 704 is right triangle-shaped, and sliding connection about spout and stop collar 703 is passed through to the one end of kicking block 704, stop collar 703 is located the downside of lower body of rod 702, and stop collar 703 passes through supporting spring and last body of rod 701 elastic connection, the bottom of stop collar 703 is the toper form. The limiting sleeve 703 is cylindrical, and an opening corresponding to the shifting block 704 is formed in one side of the limiting sleeve 703.

Because the steel balls are likely to be clamped between the two pressing heads 9 when the material poking device is used, a material poking rod 7 is arranged between the two fixing rods 6, the material poking rod 7 is composed of an upper rod body 701, a lower rod body 702 and a limiting sleeve 703, the material poking rod 7 is pushed to move downwards together in the process that the pressing plate 12 presses downwards, in the process that the material poking rod 7 moves downwards, firstly, because the bottom end of the limiting sleeve 703 is in a conical shape, the steel balls can move to one side under the pushing of the limiting sleeve 703, after the limiting sleeve 703 is abutted against the plug 18, the limiting sleeve 703 can not move any more, at the moment, because the limiting sleeve 703 is elastically connected with the upper rod body 701 through a supporting spring, the upper rod body 701 can still move downwards after the resistance of the supporting spring is overcome, under the pushing of the upper rod body 701, the lower rod body 702 can drive the poking block 704 to move downwards together, and because the lower end of the poking block 704 has an inclined surface, the steel ball can be pushed to the next fixing rod 6 under the pushing of the shifting block 704.

The lower end of the choke plug 18 is provided with a fixing ring 23, and the fixing ring 23 is connected with the movable seat 2 through an iron chain.
