Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a frock is dismantled to roller bearing inner race, includes bottom plate 1, and the both sides of 1 upper surface of bottom plate are all vertical to be provided with can follow the gliding slide bar 2 of 1 length direction of bottom plate, and the top of slide bar 2 transversely is provided with diaphragm 3, and the outer end of 3 upper surfaces of diaphragm is vertical to be provided with riser 4, and the top of riser 4 transversely is provided with backup pad 16.

Manually, the sliding rod 2 can be pulled to be adjusted to the position corresponding to the outer ring of the roller bearing according to the specification and size of the roller bearing, and then the roller bearing is placed on the transverse plate 3 to be detached.

Vertical threaded connection has one to run through to the lead screw 5 of backup pad 16 below in the backup pad 16, and the top of lead screw 5 is provided with a handle 19, and the bottom of lead screw 5 is rotated and is connected with grip block 6, and the lower surface of backup pad 16 is vertical to be provided with gag lever post 17, grip block 6 and gag lever post 17 sliding connection.

After the roller bearing is manually placed on the transverse plate 3, the handle 19 is rotated forward and backward, so that the screw rod 5 rotates forward and backward to drive the clamping plate 6 to ascend or descend until the clamping plate is contacted with the outer ring part of the roller bearing placed on the transverse plate 3, the roller bearing is fixed, and the disassembling tool can fix the roller bearing in the face of different specifications of roller bearings.

The clamping plates 6 are semi-circular arc-shaped, the two clamping plates 6 can form a complete circular ring to be contacted with the outer ring part of the roller bearing, and the bottom of the clamping plate is provided with an anti-skid pad. When the inner ring of the roller bearing is disassembled by the disassembling workpiece, the roller bearing is more stable, the clamping plate 6 can increase the friction force with the roller bearing, the roller fittings are protected, and the screw rod 5 is prevented from directly contacting with the roller bearing and damaging the roller bearing.

The limiting rod 17 can limit the rotation of the screw rod 5, and when the clamping plate 6 is driven to ascend or descend, the clamping plate 6 cannot rotate together with the screw rod 5, and the same position is kept to ascend or descend.

An electric telescopic rod 21 is vertically arranged on the upper surface of the bottom plate 1 between the two sliding rods 2, and a connecting plate 22 is transversely arranged at the top end of the electric telescopic rod 21.

When the electric telescopic rod 21 extends or contracts, the connecting plate 22 is driven to ascend or descend.

Both sides wall of connecting plate 22 all rotates and is connected with the claw 7, and the upper surface of connecting plate 22 rotationally vertically is provided with a threaded rod 9, and the top of threaded rod 9 is provided with a leader 20, and the surperficial threaded connection of connecting plate 22 has a thread bush 18, and the both sides of thread bush 18 all rotate and are connected with dwang 8, and the other end of dwang 8 rotates with the inside wall of claw 7 and is connected.

The handle 20 is rotated forward and backward manually to raise or lower the threaded rod 9 through forward and backward rotation of the threaded rod 9, and when the threaded rod 18 is raised, the inclination angle of the rotating rod 8 is changed to contract the hook 7, and when the threaded rod 18 is lowered, the inclination angle of the rotating rod 8 is changed to open the hook 7.

The connecting plate 22 and the elements mutually connected with the connecting plate 22 extend out of the hollow part of the inner ring of the roller bearing through the extension of the electric telescopic rod 21 and extend to the upper part of the roller bearing, the opening degree of the hook claw 7 is adjusted manually through rotating the handle 20 to be used for adapting the inner rings with different sizes, the hook claw 7 is buckled on the edge of the inner ring of the roller bearing in the contraction process of the electric telescopic rod 21, and the inner ring is pulled out of the roller bearing and detached through the hook claw 7 by the contraction of the electric telescopic rod 21.

The different dismantlement frock of change need not make a round trip, reduces artificial amount of labour, improves roller bearing's dismantlement efficiency, makes things convenient for the manual work to dismantle roller bearing's inner circle.

The lateral wall of slide bar 2 transversely is provided with cardboard 10, but cardboard 10 go up vertical card pole 11 that is provided with the pull, and the upper portion on card pole 11 surface transversely is provided with fixed plate 12, and the vertical reset spring 13 that is provided with between the lower surface of fixed plate 12 and the upper surface of cardboard 10, and the upper surface of bottom plate 1 is seted up and is supplied the gliding dead slot 14 of slide bar 2, and the card hole 15 with card pole 11 looks adaptation is seted up to the internal face of dead slot 14.

When the position of first slide bar 2 needs to be adjusted, artifical pull kelly 11, pull out kelly 11 from calorie hole 15, the manual work is with kelly 11 when pulling out from calorie hole 15, fixed plate 12 extrudes reset spring 13, make reset spring 13 shrink produce elasticity, drive kelly 11 with slide bar 2 and slide and adjust to with calorie hole 15 corresponding position when, under reset spring 13's elasticity drives, make kelly 11 insert in calorie hole 15, carry out the rigidity with slide bar 2, make roller bearing place on diaphragm 3 after fixing, slide bar 2 stability more.

When in work, the sliding rod 2 is pulled manually to adjust to the position corresponding to the outer ring of the roller bearing according to the specification and the size of the roller bearing, then the roller bearing is placed on the transverse plate 3, after the roller bearing is placed on the transverse plate 3 manually, the handle 19 is rotated forward and backward to make the screw rod 5 rotate forward and backward to drive the clamping plate 6 to ascend or descend until the clamping plate contacts with the outer ring part of the roller bearing placed on the transverse plate 3, the roller bearing is fixed, the connecting plate 22 and the elements mutually connected with the connecting plate 22 extend out of the hollow part of the inner ring of the roller bearing through the extension of the electric telescopic rod 21 and extend to the upper part of the roller bearing, the opening degree of the claw 7 is manually adjusted through the rotating handle 20, the claw 7 is buckled on the edge of the inner ring of the roller bearing in the contraction process of the electric telescopic rod 21, and the inner ring is pulled out of the roller bearing through the claw 7 and is detached through the contraction of the electric telescopic rod 21.
