Description of drawings
Fig. 1 is the structural representation that motor splined shaft endoporus arrangement for grinding and this device and the motor end face in the utility model is fixed together.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, the utility model is described in detail below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the structural representation that motor splined shaft endoporus arrangement for grinding and this device and the motor end face in the utility model is fixed together.As shown in Figure 1; This device comprises: installing plate 3, be fixed on the cross slide way installing plate 12 on the installing plate 3, and be fixed on the lateral slide rail secondary 11 on the cross slide way installing plate 12; Be screwed the sliding panel 10 on lateral slide rail secondary 11; Be fixed on the assembly that moves up and down on the sliding panel 10, be fixed on the rotary power assembly that moves up and down on the assembly, the emery wheel 4 that axially is connected with the rotary power assembly.Air grinder 8, emery wheel 4 and motor splined shaft 1 concentric co-axial.
The said assembly that moves up and down comprises: move up and down plate and bistrique retainer 6, move up and down guideway 7 and up-down adjustment screw 5.
In the present embodiment, said rotary power assembly is an air grinder 8.Air grinder 8 is fixed on and moves up and down plate and bistrique retainer 6, and air grinder 8 provides power by compressed air 9.
This device as shown in the figure further comprises: be fixed on the installation angle bar 13 on the installing plate 3 and below cross slide way installing plate 12.
When in use, said installing plate 3 is installed on the motor end face through the pin-and-hole on the motor end face 2.Promptly utilize the technology pin-and-hole 2 of motor end face to position, make that the center of air grinder 8 of device is coaxial with the electric machine rotational axis center.Three dowel holes are arranged on the end face of motor.
In device shown in Figure 1, lateral slide rail secondary 11 is parallel with motor shaft, makes sliding panel 10 drive air grinder 8 and can move to axial with motor shaft with emery wheel 4.Move up and down plate and bistrique retainer 6 and move up and down along moving up and down guideway 7 through up-down adjustment screw 5, it is eccentric that emery wheel 4 is produced, and realizes radial feed, removes the unnecessary surplus of endoporus of motor splined shaft 1.
In device shown in Figure 1; Sliding panel 10 and lateral slide rail secondary 11 are fixed on the cross slide way installing plate 12 through screw; Cross slide way installing plate 12 is screwed on installing plate 3, makes center in the vertical direction and the motor pivot of air grinder 8 on same plane.
In the motor splined shaft arrangement for grinding shown in Figure 1, utilize air grinder 8 rotary power to be provided to emery wheel 4.In use, at electric machine controller input 48V DC voltage in addition, the output of controller is received on the motor terminal, and power inverter and control of software through controller make the motor rotation; Air grinder 8 drives emery wheel 4 reverse rotations simultaneously, realizes the relative fricting movement of emery wheel cylinder and motor spline endoporus.Thereby remove the surplus of spline axis hole effectively, and guaranteed the concentric of spline endoporus and motor pivot.
When concrete the use; Move up and down guideway 7 and drive and move up and down plate and bistrique retainer 6 utilizes up-down adjustment screw 5 toward adjusted, it is eccentric that emery wheel 4 is produced, and the power that emery wheel 4 leans on air grinder 8 to provide rotates; Before each feeding; Utilize up-down adjustment screw 5 to make emery wheel 4 up move 0.03 millimeter, grind off 0.03 millimeter surplus at every turn, sliding panel 10 drives emery wheel 4 and does feeding circulation of 3～4 completion of left and right sides rectilinear motion simultaneously.
Motor shaft connects three-phase alternating current, through controller and software motor shaft is started, and rotation stops, and realizes the feeding circulation.
Because motor shaft rotation, the each feeding circulation of emery wheel grinds off 0.03 millimeter surplus, after reconditioning is accomplished, has guaranteed the concentric of splined shaft endoporus and motor shaft bearings at both ends.
In sum; The installing plate 3 of this motor splined shaft endoporus arrangement for grinding of the utility model can be fixed on the end face of motor; Through sliding panel 10 with move up and down the position that assembly is adjusted emery wheel 4; The rotary power assembly drives emery wheel 4 rotations, thereby be implemented under the situation of not dismounting motor motor splined shaft endoporus is carried out reconditioning.Avoid damage that the dismounting motor causes and the situation of ressembling to take place, reduced the manufacturing cost of motor.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
