[0047] Example 1: See Figure 1-7An automatic glaze dipping machine actuator includes a flip mechanism; the flip mechanism includes a flip fixing frame 11 and a flip plate; the flip fixing frame 11 is a U-shaped frame, the back of the U-shaped frame is connected to an H-shaped cantilever beam 111, and the lower surface of the outer end of the cantilever beam 111 is provided with a diagonal support frame 12; bearing holes 13 are coaxially provided on the left and right end plates of the U-shaped frame, and flip bearings 25 are correspondingly installed in the bearing holes 13;

[0048] The flip plate is divided into a flip upper plate 21 and a flip lower plate 22. The flip upper plate 21 and the flip lower plate 22 are aligned and distributed up and down, and the two have the same size; the left and right ends of the flip plate are respectively connected with a flip shaft 24, and the two flip shafts 24 are coaxially arranged. The two flip shafts 24 are respectively matched with the flip bearings 25 on the same side; the two flip shafts 24 are respectively matched with the flip bearings 25 on the same side, which can limit the flip plate and avoid deflection.

[0049] The upper surface of the flip lower plate 22 is provided with three humps 221, the upper surfaces of which are fixedly connected to the lower surface of the flip upper plate 21. The humps 221 connect the flip upper plate 21 and the flip lower plate 22 into a single unit, thereby increasing the strength of the flip plate and optimizing the stress conditions of the device, thereby reducing and evenly distributing stress on the flip plate and preventing deformation that could affect normal use.

[0050] The device also includes a flip motor 6, and the flip motor output shaft 61 is connected to the flip shaft 24; the flip motor 6 is connected to the flip shaft 24 through a key, and the angle of the flip plate can be changed by controlling the flip motor 6.

[0051] The device also includes a transmission mechanism; the transmission mechanism includes a driving wheel, a driven wheel, a tensioning wheel and a belt;

[0052] The flip upper plate 21 and the flip lower plate 22 are equidistantly provided with four pulley shaft holes along the width midline, in which the pulley shaft 31 is installed, and the top of the pulley shaft 31 is installed with a driven pulley 32; the lower surface of the flip upper plate 21 and the upper surface of the flip lower plate 22 are correspondingly provided with thrust bearings 33, which are embedded in the flip plate and cooperate with the pulley shaft 31;

[0053] The bottom end of the pulley shaft 31 extends from the lower surface of the flip lower plate 22 and serves as the final output shaft of the device.

[0054] A gap is set between the flip upper plate 21 and the flip lower plate 22; a shaft sleeve 34 is also installed on the pulley shaft 31, and the shaft sleeve 34 is clamped between the two thrust bearings 33; the shaft sleeve 34 can not only prevent the two thrust bearings 33 from offset, but also control the gap between the flip upper plate 21 and the flip lower plate 22, so that the structure of the device remains stable.

[0055] A driving motor 7 is provided on the side of the flip plate. The output shaft of the driving motor 7 is on the same side as the driven wheel 32. A driving wheel 30 is provided on the output shaft. The driving wheel 30 and the driven wheel 32 are connected by a transmission belt 5.

[0056] The driving motor 7 is fixed to the flip plate and can rotate along with the flip plate around the flip axis 24 under the action of the flip motor 6 . At the same time, the driving motor 7 transmits power to the pulley shaft 31 .

[0057] An L-shaped plate extends outward from the back panel of the tilting fixture 11, oriented in the same direction as the tilting fixture 11. The end of the L-shaped plate is connected to a motor mounting plate, to which the tilting motor 6 is fixed. The tilting motor 6 is mounted on the tilting fixture 11, and its output end is connected to the tilting shaft 24, which can improve the stability of the device.

[0058] A tensioning wheel 41 is also provided on the flip upper plate 21, and the shaft of the tensioning wheel 41 passes through the flip upper plate 21, and its lower end abuts against the upper surface of the flip lower plate 22. The tensioning wheel 41 can be used to adjust the belt to a suitable tightness and automatically adjust as the belt wears.

[0059] The transmission mechanism on the flip plate adopts a belt drive scheme of driving motor (active pulley) - multiple driven pulleys - tensioning pulley to realize the rotation of the four pulley shafts installed equidistantly along the width center line of the upper plate; the three tensioning pulleys are used to control the tension of the transmission belt.

[0060] The tensioning wheel 41 is sleeved with a ball bearing 42, which is embedded in the upper flip plate 21 and flush with the upper flip plate 21. The tensioning wheel 41 can rotate with the belt, reducing belt wear and extending the service life of the belt.

[0061] The driven wheel 32 is connected to the pulley shaft 31 by a key. The key connection allows the driven wheel 32 and the pulley shaft 31 to have better centering, and the structure is simple and easy to disassemble and adjust.

[0062] The humps 221 are located in the middle of the holes of two adjacent pulley shafts 31, which can make the stress distribution on the flip plate more uniform.

[0063] See also Figure 16-21 When the flip plate is not equipped with a hump, it can be seen that the amplitude of the flip plate is large in the first six natural frequencies, and the amplitude is manifested as a wave-like vibration of the upper and lower plates; and because the flip plate is hollow, its strength is insufficient;

[0064] See also Figure 22-27 After setting the hump between the flip plates, the deformation of the first two orders is just bending upward, and starting from the third order, it bends in a wave shape, and the deformation becomes larger and larger. Compared with before setting the hump, the total deformation is reduced, which increases the strength of the flip plate.

[0065] Example 2: See Figure 3-5 7-10. The second embodiment is substantially identical to the first embodiment, and the similarities are omitted. The difference is that a circular slot 112 is provided in the middle of the back plate of the tilting fixture 11 and the middle of the cantilever beam 111. While maintaining sufficient structural strength, the tilting fixture 11 is lightweighted to further conserve material and make the entire device more portable.

[0066] See also Figure 11-12 After the loads and constraints were added, the equivalent stress of the frame was solved, and it was found that the maximum stress was at the junction of the cantilever beam and the bracket. The analysis results concluded that the material margin of the overall model was too large and the strength was excessive, resulting in the wrong location of the equivalent stress.

[0067] See also Figure 28-33 In the entire modal analysis, the cantilever beam and the connection between the flip motor and the bracket are not affected, so a lightweight study is conducted to reduce the mass of the frame and improve its service life.

[0068] See also Figure 12 The optimized first 6 frequencies are roughly the same as those of the original fixed frame, and the vibration modes are similar except for a slightly different amplitude due to weight reduction. The deformation is also roughly the same, indicating that the structural characteristics of the optimized fixed frame are not much different from the original frame; compared with the original fixed frame, it has been optimized for weight reduction and has qualified strength.
