Detailed Description
As shown in fig. 1 and 2, motor spline shaft hoist and mount frock in this application embodiment, including adapter sleeve 1, four elasticity clamping unit 2, open adapter sleeve 1 lateral wall bottom has four mounting grooves 101, elasticity clamping unit 2 is the same and the one-to-one with both figures of mounting groove 101, each elasticity clamping unit 2 is installed in the mounting groove 101 that corresponds, each elasticity clamping unit 2 all has the exposed core, on adapter sleeve 1 overlaps the motor spline shaft, the exposed core of each elasticity clamping unit 2 stretched into adapter sleeve 1 and withstood the tank bottom surface and all exposed core mutually support of the chute of the spindle nose of the motor spline shaft that is located adapter sleeve 1, press from both sides the spindle nose.
The clamping end is clamping piece 201, and elasticity clamping unit 2 still includes spring 202, setting element, and the setting element is installed at mounting groove 101 middle part, and clamping piece 201 telescopically sets up in mounting groove 101, and spring 202 both ends support setting element, clamping piece 201 respectively. Like this, no matter how the motor internal spline axle slides along the axial of location sleeve 1 in location sleeve 1, under the effect of spring 202, the groove bottom surface in close contact with of the chute of spindle nose can both be kept all the time to holding piece 201 for all holding pieces 201 mutually support, can press from both sides tight spindle nose.
The front end of the clamping piece 201 is provided with a clamping edge 2011, and the clamping edge 2011 is a curved edge. The tank bottom surface of the chute of the spindle nose is actually a round table surface, so that a curved edge is adopted, when the clamping piece 201 clamps the spindle nose, the contact position of the clamping edge 2011 and the tank bottom surface is a small surface, and the clamping piece 201 can be more effectively prevented from damaging the tank bottom surface during clamping.
In an alternative embodiment, the radius of the curved edge is greater than the radius of the top of the bottom surface of the slot of the stub shaft.
The back end of the holding sheet 201 is provided with a groove 2012 capable of avoiding the positioning member and the spring 202. The arrangement of the groove 2012 enables the extension and retraction of the clamping piece 201 not to be hindered by the positioning element and the spring 202, and because the positioning element and the spring 202 are located in the groove 2012, the positioning element and the spring 202 can also play a role in limiting and positioning, thereby avoiding the clamping piece 201 from deflecting by too large angle.
The mounting channel 101 has a top edge 1011, a bottom edge 1012 and two side edges 1013, the positioning member is a screw 203, and the screw 203 is threadedly coupled to the top edge 1011 and the bottom edge 1012 of the mounting channel 101.
The bottom of the inner side wall of the positioning sleeve 1 is provided with a mounting chute 102.
As shown in fig. 8, this application motor spline shaft hoist and mount frock is used for this motor spline shaft 3, its structure spindle nose 301, axle body 302 and spindle nose 301 are made integratively, and axle body 302 top surface is opened threaded hole, and spindle nose 301 lateral surface has chute 3011 to the tank bottom surface 30111 internal diameter of chute 3011 from the top down increases gradually, and tank bottom surface 30111 is the face of cylinder, round table from the top down in proper order promptly, and spindle nose 301 bottom has location step 3012.
The following operation is described with reference to fig. 1-7:
the positioning sleeve 1 is horizontally placed, and the motor internal spline shaft 3 is inserted into the positioning sleeve 1 from the opening at the bottom end of the positioning sleeve 1. At this time, as shown in fig. 3 to 6, under the action of each spring 202, the clamping edges 2011 at the front ends of the clamping pieces 201 of the four elastic clamping units 2 respectively abut against the cylindrical surface area at the top of the inclined slot 3011 of the spindle head 301, so as to clamp the motor spline shaft, and the motor spline shaft hoisting tool is in an open state.
And then a lifting ring 4 is arranged at the top end of the internal spline shaft 3 of the motor.
The hoisting tool for the motor internal spline shaft 3 and the motor internal spline shaft 3 is hoisted through the hoisting ring, and the positioning sleeve 1 moves downwards until the bottom end of the positioning sleeve 1 abuts against the positioning step 3012 at the bottom end of the shaft head 301 of the motor internal spline shaft 3. At this time, as shown in fig. 7, under the action of each spring 202, the clamping edges 2011 at the front ends of the clamping pieces 201 of the four elastic clamping units 2 contract outwards and respectively abut against the middle of the circular table top at the top of the inclined slot 3011 of the spindle head 301, and the motor internal spline shaft hoisting tool is in a closed state.
The hardness of the motor internal spline shaft hoisting tool can be set to be higher than that of a common iron tool, but is softer than that of the internal spline shaft, so that the clamping sheets 201 on the motor internal spline shaft hoisting tool can clamp the motor internal spline shaft and the motor internal spline shaft cannot be damaged.
