Detailed Implementation

[0013] The recirculating ball steering multi-angle loading device includes a robotic arm 1 and a loading assembly 2 (see the attached instruction manual). Figure 1 Robotic arm 1 is an outsourced component. When robotic arm 1 is working, it can drive loading component 2 to move at multiple angles.

[0014] The robotic arm 1 is equipped with a loading component 2 (see instruction manual). Figure 1 The loading assembly 2 includes a mounting base 3, a loading motor 5, a torque sensor 6, a splined sleeve 14, an intermediate adjusting plate 13, a sliding sleeve 9, and a guide ring 8 (see the instruction manual appendix). Figure 2 , 3 and 4).

[0015] The output end of the robotic arm 1 is equipped with a mounting base 3; a drive shaft 4 and a loading motor 5 are mounted on the mounting base 3 at intervals; the loading motor 5 is connected to the drive shaft 4 through a torque sensor 6 (see the instruction manual appendix). Figure 6 and 7 When the loading motor 5 is working, it can drive the transmission shaft 4 to rotate synchronously through the torque sensor 6.

[0016] The end of the drive shaft 4 is fixed with a guide slide rod 7 via a coupling (see the instruction manual appendix). Figure 7 When the drive shaft 4 rotates, it can drive the guide slide rod 7 to rotate synchronously.

[0017] A guide slide keyway 15 is provided on the circumferential surface of the guide slide rod 7; a guide slide hole 16 is provided in the middle of the guide slide rod 7 (see the instruction manual appendix). Figure 8 and 11 ).

[0018] A sliding sleeve 9 is slidably mounted on the guide rod 7 via a guide ring 8 (see instruction manual appendix). Figure 8 ).

[0019] The sliding sleeve 9 has guide splines inside one end; the sliding sleeve 9 is slidably connected to the guide slide rod 7 through the guide splines and guide slide keyway 15 (see the instruction manual appendix). Figure 11Thus, the sliding sleeve 9 can only slide laterally relative to the guide slide rod 7; when the guide slide rod 7 rotates, it can drive the sliding sleeve 9 to rotate synchronously.

[0020] A mounting ring groove 17 is provided on the circumferential surface of one end of the sliding sleeve 9; a guide ring 8 is installed in the mounting ring groove 17; a guide pin 18 is installed inside the guide ring 8; the guide pin 18 passes through the sliding sleeve 9 and is slidably connected to the guide sliding hole 16 (see the attached instruction manual). Figure 8 and 11 The purpose of setting the guide ring 8 in this way is to enable the guide ring 8 and the guide pin 18 to slide synchronously when the sliding sleeve 9 slides. The guide pin 18 can only slide within the guide hole 16. Therefore, the guide ring 8 and the guide pin 18 have the purpose of limiting the movement range of the sliding sleeve 9.

[0021] A limiting ring ridge 19 is provided on the circumferential surface of the other end of the sliding sleeve 9; an open sliding groove A20 is provided at the end of the sliding sleeve 9 (see the instruction manual appendix). Figure 11 ).

[0022] A locking sleeve 12 is threadedly connected to one side of the limiting ring 19 (see instruction manual appendix). Figure 8 The locking sleeve 12 has an inner clamping ring 21 at one end (see the instruction manual appendix). Figure 8 When the locking sleeve 12 is tightened, the intermediate adjusting plate 13 and the splined sleeve 14 can be pressed and fixed onto the sliding sleeve 9 by the inner clamping ring 21.

[0023] There is a certain gap between the circumferential surface of the intermediate adjusting plate 13 and the spline sleeve 14 and the inner wall of the sliding sleeve 9. The purpose of this setting is to provide a certain adjustment space for the intermediate adjusting plate 13 and the spline sleeve 14 so that when changing the spline sleeve 14, the position of the spline sleeve 14 can be adjusted through the intermediate adjusting plate 13 to ensure the coaxiality of the spline sleeve 14.

[0024] A limit ring 10 is mounted on the guide rod 7 at one end of the sliding sleeve 9 (see the instruction manual appendix). Figure 8 and 11 A buffer spring 11 is fitted on the guide rod 7 between the limiting ring 10 and the sliding sleeve 9. When the sliding sleeve 9 is subjected to force and moves axially, it compresses the buffer spring 11, causing it to contract. At the same time, the sliding sleeve 9 always has a tendency to move outward under the action of the elastic force of the buffer spring 11.

[0025] One end of the sliding sleeve 9 is fitted with a splined sleeve 14 via a locking sleeve 12 and an intermediate adjusting plate 13. An adjusting protrusion A22 is provided in the center of one end face of the intermediate adjusting plate 13; an open groove B23 is provided in the center of the other end face of the intermediate adjusting plate 13; the adjusting protrusion and the open groove B23 are arranged in a cross shape (see the attached instruction manual). Figure 10).

[0026] One end of the splined sleeve 14 is provided with an adjustment protrusion B24 (see instruction manual appendix). Figure 9 The purpose of this arrangement of the intermediate adjusting plate 13 and the splined sleeve 14 is to ensure that the adjusting protrusion A22 of the intermediate adjusting plate 13 and the open groove A20 of the sliding sleeve 9 are in an insertable sliding connection; and that the open groove B23 of the intermediate adjusting plate 13 and the adjusting protrusion B24 of the splined sleeve 14 are in an insertable sliding connection. Thus, before the sliding sleeve 9 is tightened, the coaxiality of the splined sleeve 14 and the guide slide rod 7 can be adjusted by adjusting the splined sleeve 14 and the intermediate adjusting plate 13. After the splined sleeve 14 is adjusted to the appropriate position, the locking sleeve 12 is tightened and then the intermediate adjusting plate 13 and the splined sleeve 14 are pressed and fixed onto the sliding sleeve 9 by the inner clamping ring 21.

[0027] After the spline sleeve 14 is changed, the robot arm 1 drives the loading component 2 to insert the spline sleeve 14 into the input shaft of the recirculating ball steering mechanism. Then, the loading motor 5 drives the input shaft of the recirculating ball steering mechanism to rotate through the torque sensor 6, the drive shaft 4, and the spline sleeve 14 to complete the loading work. During this process, the robot arm 1 can drive the loading component 2 to move at multiple angles as needed, thus achieving the purpose of completing multiple experiments.

[0028] This multi-angle loading device for the recirculating ball steering gear is compact and ingeniously designed. It allows for the adaptive replacement of the spline sleeve 14 as needed, solving the problem of the single function of existing recirculating ball steering gear loading devices. It is particularly suitable for the experimental needs of recirculating ball steering gears.
