Abstract
The utility model discloses a novel central spindle fixing structure. The novel central spindle fixing structure comprises a central spindle and a non-adjustable wrench, wherein the central spindle is provided with a taper hole and is mounted inside a spindle. One end, being provided with the taper hole, of the central spindle is of an internal spline structure, an external spline structure which is matched with the internal spline structure of the central spindle is arranged at one end of the non-adjustable wrench, and a hexagon head structure is arranged at the other end of the non-adjustable wrench. According to the novel central spindle fixing structure, the spline structures are arranged both at the end, close to the taper hole of the spindle, of the central spindle and at one end of the non-adjustable wrench, the spline structures are in clearance fit, and thus the central spindle can be fixed. The novel central spindle fixing structure is simple in structure, easy to machine, low in cost and good in fixing performance reliability. The novel central spindle fixing structure can not be damaged easily, the dynamic balance of the central spindle is facilitated, knife handle fictional force is increased to a certain degree, and the knife handle slipping phenomenon in times of spindle processing is prevented.
Description
Technical field
The utility model relates to a kind of new shaft core fixed structure.
Background technology
A kind of fixed form that existing various axle core is conventional is to hole on axle core and main shaft, then by mounting screw, it is fixed.This fixed form need to be punched on axle core and main shaft, makes main shaft installation and removal cumbersome, also has the poor problem of fixed performance reliability simultaneously.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to be to provide that a kind of simple in structure, handling ease, cost are low, the new shaft core fixed structure of fixed performance good reliability.This structure is not fragile, facilitate the dynamic balancing of axle core, increases to a certain extent handle of a knife frictional force, and while preventing spindle processing, handle of a knife skids.
For achieving the above object, the utility model adopts following technical scheme:
A new shaft core fixed structure, comprises and is arranged on the interior axle core with taper hole of main shaft, it is characterized in that: described axle core is internal spline structure with one end of taper hole; Also comprise a back-up wrench, one end of described back-up wrench is provided with the external splines structure being connected with axle in-core spline structure.
Realizing the purpose of this utility model can also be by taking following technical scheme to reach:
Realizing a kind of embodiment of the present utility model is: the described back-up wrench other end is hexagon head structure.
Realizing a kind of embodiment of the present utility model is: described back-up wrench external splines structure is interted and is provided with in the taper hole of internal spline structure at described axle core, and formation is connected.
The beneficial effects of the utility model are:
The utility model axle core is internal spline structure with one end of taper hole, and this kind of structure can increase the frictional force with handle of a knife, and in the time of effectively preventing that main shaft from rotating, handle of a knife skids; One end of back-up wrench is provided with the external splines structure coordinating with axle in-core spline structure, is inserted in the standard spanner of back-up wrench turret head by turn, can easily realize axle core and fix, and improves fixed performance reliability; The utility model is simple in structure, and processing cost is low, not fragile, facilitates the dynamic balancing of axle core.
Accompanying drawing explanation
Fig. 1 is a kind of new shaft core fixed structure assembling schematic diagram described in the utility model.
Fig. 2 is axle core upward view described in the utility model.
Fig. 3 is back-up wrench structural representation described in the utility model.
Fig. 4 is back-up wrench top view described in the utility model.
Wherein, 1 is main shaft, and 2 is axle core, and 21 is internal spline structure, and 3 is back-up wrench, and 31 is external splines structure, and 32 is turret head.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Specific embodiment 1:
A new shaft core fixed structure, comprises and is arranged on the interior axle core 2 with taper hole of main shaft 1, described axle core 2 is internal spline structure 21 with one end of taper hole; Also comprise a back-up wrench 3, one end of described back-up wrench 3 is provided with the external splines structure 31 being connected with axle core 2 internal spline structures 21.Described back-up wrench 3 other ends are hexagon head structure 32.Described back-up wrench 3 external splines structures 31 are interted and are provided with in the taper hole of internal spline structure 21 at described axle core 2, and formation is connected.
With reference to Fig. 1, in actual use, when main shaft installation or removal, back-up wrench 3 described in the utility model is inserted and is arranged on the axle core 2 in main shaft 1, the external splines structure 31 of back-up wrench 3 is matched with the internal spline structure in axle core 2 taper holes, the turret head 32 that entangles back-up wrench 3 with standard spanner, screws standard spanner, and axle core is fixed.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
Claims (3)
