Detailed implementation manners

[0036] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the rotating and swinging platform of the present utility model will be introduced and described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0037] The present invention provides a rotating and swinging platform, in combination with Figure 1 As shown, it includes structures such as the first motor 1, load rotating shaft 3, second motor 4, etc. The first motor 1 can output rotation around the first direction. The base 2 includes a chassis 21 and two support walls 22. The two support walls 22 are respectively fixed to the chassis 21, and the entire base 2 forms a "concave"-shaped structure. The two support walls 22 among them can be vertical flat plates or curved plates with arc surfaces. The chassis 21 is installed on the output part of the first motor 1, and the output part of the first motor 1 drives the chassis 21 to rotate around the first direction, so that the entire base 2 can rotate around the first direction.

[0038] The load rotating shaft 3 is rotationally assembled to the two support walls 22 along the second direction through two sets of bearings 31. The two support walls 22 simultaneously provide support for the load rotating shaft 3, so that the load rotating shaft 3 is stably supported and can rotate relative to the two support walls 22. In combination with Figure 1 As shown, the first direction is the X-axis direction, and the second direction is the Y-axis direction. The bearing 31 supports the mechanical load rotating shaft 3, reduces the friction coefficient during its movement, and ensures its rotational accuracy.

[0039] The load rotating shaft 3 is used to fix and limit the component to be measured, that is, the load rotating shaft 3 bears the component to be measured. The component to be measured is installed on the load rotating shaft 3, and the component to be measured can move synchronously with the load rotating shaft 3.

[0040] The second motor 4 is installed on one of the support walls 22. The output part of the second motor 4 drives the load rotating shaft 3 to rotate around the second direction. The first motor 1 and the second motor 4 rotate independently, and the angle and orientation of the component to be measured can be independently controlled.

[0041] When the first motor 1 drives the base 2 to rotate in the first direction, the load rotating shaft 3, the second motor 4 mounted on the base 2, and the component under test mounted on the load rotating shaft 3 can rotate synchronously in the first direction; when the second motor 4 drives the load rotating shaft 3 to rotate in the second direction, the component under test mounted on the load rotating shaft 3 can rotate in the second direction. That is, the component under test can rotate around two different rotating shafts respectively to adjust the orientation of the component under test, so that different positions of the component under test face the detector to complete the detection process. The component under test is directly locked to the load rotating shaft 3 without transfer parts, with smaller moment of inertia, faster response speed, and cost savings.

[0042] Based on the above solution, the first motor 1 in the present utility model is a direct drive motor. A direct drive motor (DDR motor) is an advanced motor technology that drives by directly connecting to the load without the need for a gearbox, belt, or other transmission mechanisms. This design can significantly improve the accuracy, response speed, and rigidity of the system, while reducing maintenance requirements and noise. The main features of the DDR motor include high precision, high rigidity, high torque, and a compact structure. It is usually configured with a high-resolution encoder to further improve the process accuracy. In addition, due to its permanent magnet stator design, the DDR motor has a lower rotational speed but can maintain a high output torque. The direct drive motor directly drives the base 2 to rotate without other transmission mechanisms in the middle. Using the DDR motor to provide rotational power improves the rotational accuracy and makes the platform lighter.

[0043] The second motor 4 is a stepper motor. The output shaft of the stepper motor is inserted into the load rotating shaft 3 to form a key connection and is locked by bolts. As Figure 9 shown, a key hole 323 is axially provided at one end of the load rotating shaft 3, and the output shaft of the stepper motor is inserted into the key hole 323 to achieve rotational transmission. A locking hole 324 is provided perpendicular to the key hole 323, and the locking hole 324 is used to tighten the bolt, thereby tightly pressing the output shaft of the stepper motor to achieve axial tight locking.

[0044] The second motor 4 directly drives the load rotating shaft 3 to rotate without other transmission mechanisms in the middle. The present utility model uses a DDR motor and a stepper motor, with a small overall mechanism weight, small moment of inertia, faster acceleration, and higher efficiency.

[0045] Combined with Figure 1 、 Figure 2 、 Figure 3 shown, the first direction of the present utility model is the vertical direction, the second direction is the horizontal direction, and the first motor 1 is located below the base 2, bearing the weight of the base 2 and other related structures. As Figure 6 shown, which shows a schematic diagram of the first motor 1 driving the base 2 to rotate in the first direction, and the base 2 can rotate in both clockwise and counterclockwise directions. As Figure 7As shown, a schematic diagram of the second motor 4 driving the load rotating shaft 3 to rotate around the second direction is shown, and the load rotating shaft 3 can rotate in two directions, clockwise and counterclockwise.

[0046] Based on any of the above technical solutions and their combinations, a measured locking surface 32 for matching with the component to be measured is provided on the side wall of the load rotating shaft 3 of the present utility model, and a plurality of locking holes 321 for bolt connection are provided on the measured locking surface 32. Combining Figure 8 、 Figure 9 As shown, the main part of the load rotating shaft 3 is a cylindrical surface, and a measured locking surface 32 is milled on it. The measured locking surface 32 contacts the component to be measured. The measured locking surface 32 shown in the attached drawing is a plane, or it can also be other shapes adapted to the outer shape of the component to be measured. Locking holes 321 are drilled radially on the measured locking surface 32. The locking holes 321 are threaded holes. When the component to be measured is placed in place, the component to be measured is tightened and fixed by bolts. In addition, positioning holes 322 can also be provided on the measured locking surface 32. The positioning holes 322 are through holes and can be inserted and matched with the positioning posts provided on the component to be measured.

[0047] A light-shielding locking surface 33 is provided on the side wall of the load rotating shaft 3 for installing the light-shielding sheet 5; a photoelectric switch 6 for detecting the light-shielding sheet 5 is installed on the base 2. Specifically, two light-shielding sheets 5 are provided and one photoelectric switch 6 is provided. Combining Figure 8 As shown, two locking surfaces 33 are milled on the side wall of the load rotating shaft 3, and a light-shielding sheet 5 is screwed and installed by bolts respectively. The light-shielding sheet 5 is an L-shaped bent structure. One surface of it contacts the locking surface 33 and is fixed by bolts, and the other surface protrudes outward. When the light-shielding sheet 5 reaches the detection range of the photoelectric switch 6, it blocks the photoelectric switch 6 to achieve in-place triggering. By setting the light-shielding sheet 5 to detect the rotation position of the load rotating shaft 3, when the light-shielding sheet 5 reaches the photoelectric switch 6, the load rotating shaft 3 stops rotating. When in use, the measured locking surface 32 faces upward and is parallel to the bottom surface of the DDR motor at the same time, and this is the initial state; when the stepping motor rotates, the light-shielding sheet 5 passes through the photoelectric switch 6 to trigger a signal.

[0048] Combining Figure 6 、 Figure 7As shown, the first motor 1 is used to drive the base 2 to rotate 360 degrees at any angle. The base 2 can rotate 360 degrees at any angle, and can rotate 360° clockwise or 360° counterclockwise. The second motor 4 drives the load rotating shaft 3 within an angular range of 180 degrees. The load rotating shaft 3 can rotate 90° clockwise or 90° counterclockwise, with a total swing deflection of 180°; ensuring that the component to be tested is fully exposed to the detector is sufficient. The base 2 rotates 360° powered by a DDR motor, the stepping motor is the power for swinging, and the photoelectric switch limits the 180° rotation of the stepping motor. The load rotating shaft is directly locked and contacted with the object to be detected, making the overall mechanism lightweight and simple, and realizing the large-range detection of the object to be detected.

[0049] Combined with Figure 4 、 Figure 5 As shown, the base 2 is equipped with a cable tie fixing seat 23. The cable tie fixing seat 23 is used to cooperate with a cable tie to fix the cable, cooperate with the cable tie to fix the cable, form a restraint on the cable, and the cable tie fixes the cable on the cable tie fixing seat 23.

[0050] Combined with Figure 1 、 Figure 8 One end of the load rotating shaft 3 is provided with a limiting ring platform 301, and the other end is provided with a ring groove 302. The ring groove 302 is used to install a circlip 34. A circlip is also called a retaining ring or snap ring and belongs to a type of fastener. It is usually installed in the shaft groove or hole groove of a machine or equipment. Its purpose is to form a certain distance between two objects through its strong elasticity and ductility, so as to better fix these objects and prevent the parts on the shaft or hole from moving axially. When assembled in place, the circlip 34 and the limiting ring platform 301 respectively form axial limits on the load rotating shaft 3 from both ends, which can ensure that the axial position of the load rotating shaft 3 cannot move. Only setting one ring groove 302 to install the circlip 34 can simplify the assembly process.

[0051] Combined with Figure 1 As shown, in the present utility model, fixing lugs 11 are provided on the outer shell of the first motor 1. Fixing holes are provided at the four corners of the fixing lugs 11 for bolt fixing, and are used to lock and fix the first motor 1 to the detection device to fix the entire device.

[0052] The operation process of the entire platform: Lock and fix the entire platform to the detection device through the fixing lugs 11 at the bottom of the DDR motor; lock the component to be tested to the tested locking surface 32 of the load rotating shaft 3; connect the wires and power on, control the DDR motor to rotate 360° clockwise / counterclockwise, and control the stepping motor to rotate and swing 90° clockwise / counterclockwise. At this time, the object to be detected can be detected at any angle during the 360° rotation and 180° swing.

[0053] The utility model uses DDR as the rotation power to improve the rotation accuracy and lighten the platform; the stepper motor is paired with an optoelectronic switch for position limit, saving cost and reducing weight; the object to be detected is directly locked to the load rotating shaft without transfer parts, with fast response speed and cost savings; the overall mechanism is small in weight and moment of inertia, faster in speed increase and higher in efficiency; the overall mechanism is lightweight and simple, facilitating installation and debugging.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
