Abstract
The utility model relates to a bushing dismounting device, which comprise a supporting sheath, a bolt and a nut, wherein the bolt penetrates through an inner hole of a bushing and blocks the bushing, and the nut is rotatablely arranged at the tail end of the bolt and leans against the supporting sheath. The nut is rotated, so that the bolt approaches the nut and pushes the bushing upwards to dismount the bushing. The dismounting process is convenient and simple.
Description
Technical field
The utility model relates to mechanical dismounting field, especially, relates to the device that a kind of lining that interference is installed disassembles.
Background technology
Lining is widely used in various plant equipment.Usually, lining is installed on the installation workpiece of this plant equipment through interference fit.During dismounting,, perhaps cool off this lining,, reach the purpose of this lining of dismounting so that this lining and this workpiece break away from through heating the workpiece of this plant equipment.Yet this dismounting mode is high to the requirement of equipment, and trivial operations is dangerous, and damages this workpiece or this lining easily.In addition, should the dismounting mode outdoor can't the use, caused the limitation of using.
The utility model content
The utility model purpose is to provide a kind of lining provision for disengagement for convenience detach, to solve the unsafe problem of trivial operations in the prior art.
To achieve these goals, the utility model provides a kind of lining provision for disengagement, comprises a support set; One bolt, bolt pass the endoporus of lining, and the lining of fending off; And a nut, the nut rotation is installed on the end of bolt, and against support set.
Further, bolt comprises the screw rod that the head and of the lining of fending off is connected with head, and screw rod passes the endoporus of lining, and nut is installed on the end of screw rod.
Further, the diameter of head is greater than the diameter of bore of lining and less than the external diameter of lining.
Further, two pads are installed on the screw rod, wherein a pad lays respectively between lining and the head; An other pad is between support set and nut.
Further, support set is the tubular structure of an end opening, and support set and openend opposing end faces are provided with the through hole that supplies screw rod to pass through.
Further, support set is the tubular structure of an end opening, and openend is sheathed on lining.
Further, bolt comprises the screw rod that the head and of the lining of fending off is connected with head, and support set and openend opposing end faces are provided with the through hole that supplies screw rod to pass through.
Further, the diameter of head is greater than the diameter of bore of lining and less than the external diameter of lining.
The utlity model has following beneficial effect: the nut rotation of the utility model is installed on bolt; And nut is against support set; Rotating nut, bolt to this nut near, utilize active force and the principle of reaction force between nut and the bolt; The head pushing tow lining of bolt is broken away from, to reach purpose convenient, the disassembled simply lining from workpiece mounting hole.
Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.
To do further detailed explanation to the utility model with reference to figure below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the sketch map of the lining provision for disengagement of the utility model preferred embodiment.
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please with reference to Fig. 1, the utility model provides a kind of provision for disengagement that a lining 4 is disassembled from a workpiece 3 be convenient to.This provision for disengagement comprises a bolt 1, a support set 5, a nut 7 and two pads 2.
This lining 4 comprises a sleeve part 41 and a vertical outward extending convex shoulder 42 of periphery by sleeve part 41.Sleeve part 41 is accommodated the installing hole that is fixed in workpiece 3, so that this workpiece 3 is played the liner effect.Convex shoulder 42 is against this workpiece 3.
This bolt 1 comprises that a diameter is substantially equal to the screw rod 12 that the head 11 and of the external diameter of this sleeve part 41 is connected with head 11.Screw rod 12 is provided with external screw thread away from these head 11 places.Head 11 diameters and less than the diameter of the convex shoulder 42 of lining 11.
This support set 5 is the tubular structure of an end opening, so that support this nut 7.This support set 5 is provided with the through hole that supplies this screw rod 12 to pass through with the openend opposing end faces.
During use, this support set 5 is replaced and is installed on this workpiece 3, and is sheathed on this lining 4, and makes the convex shoulder 42 of this lining 4 accommodate the openend of this support set 5.Wherein a pad 2 is sheathed on screw rod 12, screw rod 12 is passed successively endoporus and the through hole of support set 5 of the sleeve part 41 of lining 4 again.At this moment, this pad 2 is replaced this sleeve part 41 and head 11 respectively.An other pad 2 sheathed screw rods 12, and replace this support set 5.This nut 7 is installed on the end of this screw rod 12.
When dismantling this lining 4, screw this nut 7, screw rod 12 with respect to this nut 7 to this nut 7 near.The head 11 of bolt 1 promotes the sleeve part 41 of this lining 4, to force this lining 4 in the installing hole of workpiece 3, to break away from and to accommodate in this support set 5.At this moment, only need this nut 7 of pine oil, take off bolt 1, in this support set 5, take out this lining 4 again and get final product, convenient and simple for operation, and can not damage this workpiece 3 or lining 4.
Significantly, pad 2 is just in order to reduce friction.In other embodiments, also can not establish these pads.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
