Abstract
The utility model relates to a shaft sleeve withdrawal tool. A movable block (1) is matched with a sleeve (2), the sleeve (2) is connected with a stress disc (4) via a stay bolt (3), a wrench screw rod (5) is screwed into a bolt hole on the stress disc (4), and thus, a working whole body can be formed. The accuracy and surface finish of the external surface of a shaft sleeve can not be damaged during dismounting process after the utility model is used, so the repeated use rate of the shaft sleeve is high and the service life thereof is long. The utility model has the advantages of simple structure and convenient operation, and the utility model can be made into corresponding serial products according to the different specifications of the shaft sleeves.
Description
The utility model relates to a kind of axle sleeve extracting tool.
At present, in the installation of pump and the maintenance, when dismounting axle Upper shaft sleeve, dismounting axle sleeve instrument commonly used mostly is to utilize concavo-convex principle (promptly design groove structure on axle sleeve, be used to dismantle on the instrument of axle sleeve and design bulge-structure) to reach the dismounting purpose.In unloading process, with the extracting tool of above version, often keep away unavoidably and will beat axle sleeve, can make the axle sleeve surface stay mechanical scar like this; Especially use the pump of mechanical seal, very high to the precision and the fineness requirement of sleeve outer surface, outer round surface will be processed by grinding machine after chromium plating, has stayed scar owing to beaing through hammer.Reuse as axle sleeve, the leakage of medium is unavoidable, and in order to guarantee the excellent sealing effect of mechanical seal on the pump, axle sleeve just needs to upgrade.
The purpose of this utility model is not to be damaged for the precision of protecting sleeve outer surface and fineness, can reuse axle sleeve, and mechanical seal keeps good sealing effectiveness on the pump and make; Thereby self-lock mechanism on the utilization mechanics provides a kind of instrument of improved dismounting axle sleeve.
Task of the present utility model is achieved in that by movable block (1) and sleeve (2) and matches, sleeve (2) is connected by stay-bolt (3) with relay disk (4), spanner screw rod (5) is screwed in the center screw on the relay disk (4), and it is whole to form a job.The internal diameter of the movable block of some compositions (1) be disassembled axle sleeve and match, outer surface size and sleeve (2) inner surface size matches, its tapering is less than 1:15.The inner surface size of sleeve (2) and movable block (1) outer surface size match, and its tapering has the form of flanges structure less than 1:15 at big first end, on 4～8 bolts hole are arranged.Stay-bolt (3) is the connector of sleeve (2) and relay disk (4), and nut is being twisted at its two ends.The center of relay disk (4) has screw and spanner screw rod to match.Spanner screw rod (5) is screwed into the center bolt on the relay disk (4), is the element that this instrument produces pulling force P.
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is the structural representation according to a kind of axle sleeve extracting tool that the utility model proposes.Among the figure: (1) movable block; (2) sleeve; (3) stay-bolt; (4) relay disk; (5) spanner screw rod; (6) axle; (7) axle sleeve; P is a pulling force.
Fig. 2 is a major part of the present utility model---the structural representation of sleeve.
Fig. 3 is a major part of the present utility model---the structural representation of movable block.
Below in conjunction with accompanying drawing 1, the utility model is described in further detail.
This instrument is matched by movable block (1) and sleeve (2), and sleeve (2) is connected by stay-bolt (3) with relay disk (4), and spanner screw rod (5) is screwed in the center screw on the relay disk (4), and it is whole to form a job.The internal diameter of movable block (1) be disassembled axle sleeve and match, outer surface size and sleeve (2) inner surface size matches, its tapering is less than 1:15; Be processed into hollow cone, be cut into some (five equilibrium is generally 3～8) then, the gap size between piece and the piece is 2～4 millimeters.The inner surface size of sleeve (2) and movable block (1) outer surface size match, and its tapering has the form of flanges structure less than 1:15 at big first end, on 4～8 bolts hole are arranged.The material of movable block (1) and sleeve (2) is a Fine Steel Casting iron.For the frictional force between piece that takes in sail (1) and the sleeve (2), increase the frictional force between movable block and the axle sleeve, just can obtain good self-locking effect.For this reason, at the outer surface of movable block (1) or the topped one deck non-ferrous metal of inner surface or its alloy of sleeve (2), for example brass, aluminium etc., also can being coated with lubricating grease, to increase the frictional resistance of movable block (1) between inside and outside poor, thereby can reach good self-locking effect.Stay-bolt (3) is the connector of sleeve and relay disk (4), and nut is being twisted at its two ends.The center of relay disk (4) has screw and spanner screw rod to match.Spanner screw rod (5) is screwed into the center screw on the relay disk (4), is the element that this instrument produces pulling force P.Pull bar screw rod (3), the even Fine Steel Casting iron of material of relay disk (4) and spanner screw rod (5).
During operation, earlier sleeve (2) is inserted on the axle that to dismantle, then movable block (1) is packed between sleeve (2) and the axle sleeve, note the cooperation on two inclined-planes, beat movable block (1) gently with hand hammer, connect down with stay-bolt (3) sleeve (2) and pulling force disk (4) are connected together, spanner screw rod (5) is screwed into the screw on the relay disk (4), and withstands mutually with the top wire hole of axle head.Then, tighten spanner screw rod (5) (promptly adding upper pulling force P), at this moment, as the skidding on the axle sleeve surface of this instrument occurs, only need urgent once more movable block (1) to get final product, further tighten spanner screw rod (5), until axle sleeve is unloaded down from axle.After axle sleeve unloads from axle, make to be added on the opposite external force of pulling force P direction (available hand hammer beats) on sleeve (2), axle sleeve just can separate with this instrument, and the purpose of dismantling axle sleeve has like this reached.
The utility model has the advantages that to make the axle sleeve that is disassembled not beat axle sleeve by external force, just can successfully pull down, and do not stay mechanical scar, can reach the good effect of reusing. In addition, need to and not process groove structure in the axle sleeve design yet. This instrument is easy to use and reliable, and science simple in structure can be made corresponding series of products according to the different size of axle sleeve.
