[0020] Please see Figure 1-4 This embodiment provides a locking sleeve mounting device for fitting the locking sleeve 200 onto the annular portion 101 of the workpiece 100. The annular portion 101 has a notch 102, and the inner ring of the locking sleeve 200 has a protrusion 201 matching the size of the notch 102. The locking sleeve mounting device includes: The feeding mechanism 1 includes a feeding table 11, a guide rail 12, and a guide rail motor 13. The feeding table 11 is used to place the locking sleeve 200 to be installed. The bottom of the feeding table 11 is mounted on the guide rail 12. The guide rail motor 13 is mounted on the end of the guide rail 12. The guide rail motor 13 is used to push the feeding table 11 to move between the first end and the second end of the guide rail 12. Mounting platform 2, which is used to place the workpiece 100 to be installed, is located at the bottom of the second end of the guide rail 12; The mounting mechanism 3 includes a bracket 31, a lifting motor 32, a lifting plate 33, a rotary motor 34, and a mounting arm 35. The lifting motor 32 is mounted on the bracket 31, the lifting plate 33 is mounted on the output end of the lifting motor 32, and the lifting motor 32 is used to drive the lifting plate 33 to move vertically. The rotary motor 34 is mounted on the lifting plate 33, and the mounting arm 35 is mounted on the output end of the rotary motor 34. The mounting arm 35 is located at the bottom of the second end of the guide rail 12. At least a portion of the outer diameter of the mounting arm 35 is the same as the inner diameter of the locking sleeve 200. A movable push plate 36 for engaging in the notch 102 of the annular portion 101 is mounted on the outer wall of the mounting arm 35. A torque sensor connected to the movable push plate 36 is provided inside the mounting arm 35.

[0021] The output end of the lifting motor 32 and the output end of the rotary motor 34 can be configured as a motor shaft assembly for transmission, which drives the corresponding downstream component to reciprocate through the stroke motion, such as the output end of the lifting motor 32, or drives the corresponding component to rotate through the gear or other components at the end of the motor shaft, such as the output end of the rotary motor 34.

[0022] Based on the above structure of this utility model, in the process of use, firstly, the operator places the locking sleeve 200 to be installed on the feeding table 11. The feeding table 11 can be an annular column with a hollow groove and a shape similar to the workpiece 100. The guide rail motor 13 of the feeding mechanism 1 first pushes the feeding table 11 to move along the guide rail to the position of the second end of the guide rail 12, so that the feeding table 11 is positioned directly below the mounting arm 35. Then, the lifting motor 32 in the mounting mechanism 3 drives the lifting plate 33 to move downward, so that the end of the mounting arm 35 puts the locking sleeve 200 on. It is worth noting that in this step, the locking sleeve 200 is placed at a preset angle, so that after the locking sleeve 200 is put on and picked up, the position of the movable push plate 36 of the mounting arm 35 is exactly matched with the position of the protrusion 201 of the locking sleeve 200.

[0023] After the locking sleeve 200 is picked up, the mounting arm 35 of the mounting mechanism 3 is reset, so that the guide rail motor 13 of the feeding mechanism 1 can push the feeding table 11 along the guide rail for the second time to the position of the first end of the guide rail 12, so that the mounting table 2 is positioned directly below the mounting arm 35, and the feeding table 11 will not obstruct the mounting arm 35. The operator places a workpiece 100 to be installed on the mounting table 2 in advance. Then, the lifting motor 32 in the mounting mechanism 3 drives the lifting plate 33 to move downward, so that the end of the mounting arm 35 first probes into the annular part 101 of the workpiece 100, and the movable push plate The movable push plate 36 is elastically engaged in the annular portion 101 and abuts against the inner wall of the annular portion 101, stopping the operation of the lifting motor 32. Then, the rotary motor 34 starts to rotate. At this time, the movable push plate 36 begins to rotate relative to the annular portion 101. The torque sensor on one side of the movable push plate 36 obtains stable torque data until the movable push plate 36 rotates to the notch 102 position of the annular portion 101, causing the elastic force of the movable push plate 36 to be released. The width of the movable push plate 36 matches the notch 102 and is engaged in the notch 102 of the annular portion 101, achieving successful angular positioning.

[0024] After successful positioning, the lifting motor 32 in the installation mechanism 3 drives the lifting plate 33 to move downwards, and the main body of the installation arm 35 penetrates into the workpiece 100, so that the locking sleeve 200 is fitted onto the outer surface of the annular portion 101. At this time, a preset pressure value can be set by the pressure sensor installed on the installation arm 35. By judging the pressure, the locking sleeve 200 is completely fitted into the depth of the annular portion 101, and the bottom surface of the locking sleeve 200 is pressed against the outer peripheral plane of the annular portion 101 on the workpiece 100. At this time, the installation of the workpiece 100 and the locking sleeve 200 is completed, and the installation arm 35 is lifted and reset.

[0025] Based on the above structure, the mounting arm 35 can be rotated by the rotary motor 34, and the movable push plate 36 can be used to engage with the notch 102 on the workpiece 100 to achieve positioning, thus enabling the rapid installation of the locking sleeve 200. Therefore, when the mounting arm 35 enters the annular portion 101, the mounting arm 35 can be rotated by the rotary motor 34, thereby rotating the movable push plate 36 relative to the annular portion 101. During the rotation, if the position is reached, the movable push plate 36 will engage with the notch 102. The positioning method is simple and efficient, and the determination can be made quickly and accurately using only the torque sensor of the movable push plate 36.

[0026] In another embodiment, a spring bead 37 is installed on the outer wall of the mounting arm 35. The spring bead 37 is used to support the inner wall of the locking sleeve 200 when the locking sleeve 200 is removed from the mounting platform 2 by the mounting arm 35, so as to prevent the locking sleeve 200 from slipping off the mounting arm 35. Specifically, multiple spring beads 37 are provided, and the multiple spring beads 37 are equally spaced on the outer wall of the mounting arm 35. In the default state, the spring beads 37 are set to be supported by the spring inside the mounting arm 35, so that the spring beads 37 protrude from the small holes on the mounting arm 35. During the process of putting the locking sleeve 200 on, due to the compression of the inner wall of the locking sleeve 200 on the spring beads 37, the spring inside the spring beads 37 is compressed, and the spring beads 37 are pressed into the mounting arm 35. At this time, the friction of the spring beads 37 supporting the locking sleeve 200 can effectively prevent the locking sleeve 200 from falling off the mounting arm 35.

[0027] Of course, in another embodiment, there are multiple combinations of the notch 102 and the protrusion 201, and the number of movable push plates 36 matches the number of combinations of the notch 102 and the protrusion 201. For example, the workpiece 100 may be provided with two combinations of the notch 102 and the protrusion 201 spaced 180 degrees apart. Therefore, when positioning, the two movable push plates 36 need to be simultaneously engaged in the two notches 102.

[0028] In another embodiment, the movable push plate 36 is provided with an inclined surface that decreases in size from the top to the bottom of the mounting arm 35, so that it can easily enter the annular portion 101 during the downward movement of the mounting arm 35, and the movable push plate 36 can retract smoothly to avoid jamming.

[0029] The bracket 31 in this application is installed between the feeding mechanism 1 and the mounting platform 2, so that the horizontal position of the mounting arm 35 can be set exactly on the mounting platform 2, and after the feeding platform 11 is moved to the second station at the second end, the mounting arm 35 can be aligned with the feeding platform 11.

[0030] It is worth noting that the mounting arm 35 in this application actually adopts a multi-segment design. The top segment of the mounting arm 35 has a portion with a larger outer diameter that matches the inner diameter of the locking sleeve 200, used for fitting the locking sleeve 200, and the spring ball 37 is located on the upper half with the larger outer diameter. The bottom segment with the movable push plate 36 has a size no larger than the inner diameter of the annular portion 101. Preferably, the outer diameter of the movable push plate 36 in its maximum open state is still smaller than the inner diameter of the locking sleeve 200.

[0031] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0032] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0033] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
