Abstract
The invention discloses a separation tool for a locked hole and shaft. The separation tool comprises a driving assembly and a clamping assembly, and the driving assembly and the clamping assembly are connected. The driving assembly comprises a threaded shaft and a connecting plate, and the clamping assembly comprises clamping arms. A circular cone head is arranged at one end of the threaded shaft, a driving block is arranged at the other end of the threaded shaft and is a regular polygon stretching body, the connecting plate is a disc-shaped stretching body, and a threaded hole is formed in the center of the connecting plate. The separation tool has the advantages that the locked hole and shaft can be easily separated through the tool, and the producing and assembling time is shortened.
Description
Technical field
The present invention relates to mechanical, hand-driven instrument, being specifically related to a kind of instrument for being separated mutual locking hole axle.
Background technology
Coordinating between hole with axle can be divided into matched in clearance, interference fit, interference fits, and wherein interference fit is by negative common difference and in the axle cutter inlet hole of band tapering, carries out fixing assembling.The situation that the diameter of axle is excessive or aperture is too small is there will be in the assembling process of interference fit.In the face of hole axle need be separated by such situation, again process, re-assembly.But the hole axle of interference fit is separated very difficult.To be separated hole axle.Need to carry out strike dismounting with hammer to the direction contrary with assembly direction.But this dismounting mode makes discontinuity.Affect the progress be separated between the axle of hole.Therefore a kind of brand-new hole axle separating tool now need be provided, solve above-mentioned technical problem by this instrument.
Summary of the invention
The deficiency of integrated background technology of the present invention provides a kind of locked hole axle separating tool, and this instrument easily can realize the separation of locked hole axle, has saved the time of producing assembling.
The invention provides following technical proposals: a kind of locked hole axle separating tool, comprise driven unit, clamp assembly, described driven unit is connected with described clamp assembly.Described driven unit comprises thread spindle, connecting plate, and described clamp assembly comprises clamping arm.One end of described thread spindle is provided with nose cone, and the described thread spindle other end is provided with drive block, and described drive block is regular polygon extrusion.Described connecting plate is dish type extrusion, and the center of described connecting plate is provided with screwed hole, and the internal thread of described screwed hole screws mutually with the external screw thread of described thread spindle.Described clamping arm one end is provided with snap fit, the other end of described clamping arm is flexibly connected with the edge of described connecting plate, the body of described clamping arm is Curved, and the quantity of described clamping arm is at least two, and described clamping arm circular array shape is distributed in described connecting plate surrounding.
Further, described drive block is square extrusion.
Further, the number of described clamping arm is four.
Beneficial effect of the present invention: the external screw thread of thread spindle shown in this instrument screws with the internal thread of described connecting plate and coordinates.The driving force being separated described hole axle is provided by rotating described thread spindle.This instrument easily can realize the separation of locked hole axle, has saved the time of producing assembling.
Accompanying drawing explanation
Fig. 1 is the structural representation of locked hole of the present invention axle separating tool.
Fig. 2 is the top view of Fig. 1.
