Ground illustrates the principles of the present invention, and the utility model is not limited to described preferred embodiment, the scope of the utility model by
Claims limit.The utility model is described in detail referring now to illustrative embodiment, some embodiments are shown in attached drawing
In.Be described below with reference to attached drawing carry out, unless otherwise indicated, otherwise same reference numerals in different figures represent it is identical or
Similar element.Scheme described in following exemplary embodiment does not represent all schemes of the utility model.On the contrary, these
Scheme is only the example of the system and method for the various aspects of the utility model involved in appended claims.
It is carried out in detail below in conjunction with installation and removal device of the Fig. 1 to Fig. 2 to embodiment according to the present utility model
Description, wherein Fig. 1 is the perspective view for showing the installation and removal device 10 of embodiment according to the present utility model, and Fig. 2 is to show
The cross-sectional view of installation and removal 10 use state of device of embodiment according to the present utility model.
As shown in Fig. 2, locking nut 30 resists grinding wheel 20 and is tightened on main shaft 40, so that grinding wheel is locked to main shaft 40
On.Main shaft 40 is driven by motor (not shown), to rotate around center axis thereof I-I.By making locking nut 30 and main shaft
Grinding wheel can be installed on main shaft or disassemble from main shaft by 40 relative rotation.
Mounting and dismounting device 10 includes locking nut back-up wrench 1 and main shaft rotary spanner 2.Locking nut back-up wrench
1 is used for the position of positioning and locking nut 30, prevents it from circumferentially rotating.Preferably, locking nut back-up wrench 1 is splined spanner,
The nut overlap aperture of the splined spanner is set on 30 periphery of locking nut, utilizes nut overlap aperture inner circumferential and locking nut periphery
Spline fitted limit locking nut 30 and circumferentially rotate, locking nut 30 is located in suitable position.
Main shaft rotary spanner 2 includes spindle drive mandrel 3 and force handle portion 22, and spindle drive mandrel 33 is passed through and is arranged
The inner hole of locking nut 30 in locking nut back-up wrench 1 cooperates with spindle nose.In a preferred embodiment, main shaft passes
The end of moving mandrel 3 forms multiple pins being provided projectingly, and the pin hole that the multiple pin being provided projectingly is arranged with spindle nose is matched
It closes, so as to drive main shaft 40, relative to being set in locking nut back-up wrench by the rotation spindle drive mandrel 3
It is rotated in 1 and by its locking nut 30 fixed, and then grinding wheel 20 is fastened on main shaft 30 or unloads it from main shaft 30.
In a preferred embodiment, spindle drive mandrel 3 and force handle portion 22 are formed as two individual components, exert a force
The head of handle portion 22 is formed with the spline pin being provided projectingly, and can be inserted into the spline that the end of spindle drive mandrel 3 is formed
Hole, thus by that spindle drive mandrel 3 can be driven to rotate the force force of handle portion 22, and then main shaft 40 is driven to rotate.This
Field technical staff is appreciated that spindle drive mandrel 3 and force handle portion 22 can be formed as one component.
Preferably, force handle portion 22 is torque spanner.Torque spanner is inserted by the protrusion spline that one end is formed
In the centre bore formed on 3 end of spindle drive mandrel, specifically, the centre bore is formed in the separate of spindle drive mandrel 3
The end of main shaft 40, to apply the torsion for driving spindle drive mandrel 3 to rotate.Generally, the numerical value of torsion be set in 30N with
Between 40N.
Use state as shown in Figure 2, when needing to install grinding wheel 20, along first direction (such as clockwise direction) rotation
The rotary force of torque spanner, torque spanner is transmitted to main shaft 40 via spindle drive mandrel 3 engaged therewith, to drive main shaft 40
It is rotated along first direction around central axis I-I relative to the fixed locking nut 30 of nut back-up wrench is locked, thus by sand
Wheel 20 is pushed down and is fastened on main shaft 40.When needing to unload lower grinding wheel 20, along with first party in the opposite direction (such as counterclockwise
Direction) rotary torsion spanner, equally, the rotary force of torque spanner can be transmitted to main shaft 40 via spindle drive mandrel 3, to drive
Main shaft 40 is rotated around central axis I-I in a second direction relative to the fixed locking nut 30 of nut back-up wrench that is locked, from
And locking nut is mutually separated with main shaft and unloads grinding wheel 20 from main shaft 40.
It is different from installing or removing traditional tooling of grinding wheel, root come revolving wheel itself by hammer and spanner as a result,
It is combined according to the installation and removal device 10 of the utility model by torque spanner 22 and spindle drive mandrel 3 come live spindle 40
And grinding wheel 20 is installed on main shaft 40 or unloads grinding wheel 20 from main shaft 40.Since the numerical value of torque spanner 22 can shift to an earlier date
Setting, therefore coupling mechanism force of the grinding wheel 20 relative to main shaft 40 has been efficiently controlled, so that grinding wheel 20 is more easily installed to master
It is unloaded on axis 40 or from main shaft 40 without being damaged to main shaft 40.In addition, the installation and removal device of the utility model
10 also have many advantages, such as that structure is simple, facilitate operation.
It will be understood by those skilled in the art that the inner circumferential of the locking nut overlap aperture of the locking nut fixed part can adopt
The auxiliary section cooperated with the periphery for other and the locking nut for being different from spline, such as the lock of the locking nut fixed part
Radially protruding part is arranged in the inner circumferential of tight nut overlap aperture, and the periphery of the locking nut is provided with concave portion, recessed by protrusion
Enter the cooperation in portion to circumferentially rotate to limit the opposite of the two when the locking nut fixed part is set on the locking nut.
As previously mentioned, although being illustrated in explanation by reference to exemplary embodiment of the attached drawing to the utility model,
But the utility model is not limited to above-mentioned specific embodiment, the protection scope of the utility model should by claims and its
Equivalents limit.
