The sanding belt deflection correction wheel 44 is rotatably installed on the sanding belt deflection correction drive mechanism. The sanding belt 6 passes around the sanding belt deflection correction wheel 44. The sanding belt deflection correction wheel 44 can correct the sanding belt 6 wrapped around its periphery under the drive of the sanding belt deflection correction drive mechanism.

[0090] In this embodiment, if Figures 1 to 4As shown, in this embodiment, by providing a sanding belt edge detection device and a sanding belt correcting device 4, it is convenient to detect the width edge of the sanding belt 6 in real time through the sanding belt edge detection device, which is beneficial to obtain the offset condition of the sanding belt 6 and feed back the offset condition of the sanding belt 6 to the control processing unit, so that the control processing unit can control the sanding belt correcting drive mechanism to drive the sanding belt correcting wheel 44 according to the offset condition of the sanding belt 6 to correct the sanding belt 6 wound around the outer periphery of the sanding belt correcting wheel 44.

[0091] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the sand belt deviation correction device 4 in this embodiment is installed on the upper front end of the right side mounting plate of the mounting seat 1, and the sand belt deviation correction driving mechanism included in the sand belt deviation correction device 4 is specifically a driving cylinder 2 43.

[0092] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, a fixed support plate 40 is installed on the upper front end of the right side mounting plate of the mounting seat 1 in this embodiment, and the fixed support plate 40 is fixedly installed on the upper front end of the right side mounting plate of the mounting seat 1 by bolts, and the front end of the fixed support plate 40 extends forward and protrudes out of the front side mounting plate of the mounting seat 1; further, the upper end of the fixed support plate 40 is fixedly connected to a connecting support block 41, and a rotating mounting groove is provided in the middle part of the connecting support block 41, and a rotating support plate 42 is rotatably installed in the rotating mounting groove, and the upper end of the rotating support plate 42 is rotatably installed on the connecting support block 41 through a rotating support shaft 421.

[0093] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the driving cylinder 2 43 in this embodiment is horizontally installed on the lower end of the right side surface of the rotating support plate 42, and the push rod 2 provided on the driving cylinder 2 43 passes through the rotating support plate 42 horizontally to the left. The end of the push rod 2 passing through one end of the rotating support plate 42 can be stopped with the fixed support plate 40 under the drive of the driving cylinder 2 43. The upper end of the right side surface of the rotating support plate 42 is horizontally connected with the support shaft 2, and the support shaft 2 extends horizontally to the right. The sanding belt correction wheel 44 is rotatably installed on the right end of the support shaft 2 through the bearing sleeve.

[0094] In this embodiment, if Figure 1 , Figure 2 and Figure 3As shown, the working condition of the driving gas introduced into the driving cylinder 2 43 is controlled by the control processing unit, so that the driving cylinder 2 43 drives the push rod 2 to extend and retract so as to stop against the fixed support plate 40, and under the pressure of the sand belt 6 wound around the outer circumference of the sand belt deviation correction wheel 44, the inclination direction and the inclination angle of the rotating support plate 42 are adjusted, and the sand belt 6 deviates on the sand belt deviation correction wheel 44 according to the principle of going up but not down during the transmission process, thereby, the sand belt 6 is corrected by adjusting the inclination direction and the inclination angle of the rotating support plate 42.

[0095] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, when the sanding belt 6 deviates to the right, the control processing unit controls the driving cylinder 2 43 to drive the push rod 2 to retract. Under the pressure of the sanding belt 6 wound around the outer circumference of the sanding belt correcting wheel 44, the lower end of the rotating support plate 42 deflects toward the side close to the fixed support plate 40, so that the left end of the sanding belt correcting wheel 44 is lifted to form a high end, so that the sanding belt 6 deviates to the left until it is aligned; in addition, when the sanding belt 6 deviates to the left, the control processing unit controls the driving cylinder 2 43 to drive the push rod 2 to extend, and the push rod 2 and the fixed support plate 40 push, so that the lower end of the rotating support plate 42 deflects toward the side away from the fixed support plate 40, so that the right end of the sanding belt correcting wheel 44 is lifted to form a high end, so that the sanding belt 6 deviates to the right until it is aligned; in addition, the control processing unit controls the working condition of the driving cylinder 2 43 to control the detection offset result obtained by the sanding belt edge detection device detecting the width edge of the sanding belt 6.

[0096] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the driving cylinder 2 43 in this embodiment is connected to the air supply device through the air supply pipe. The specific structure of the driving cylinder 2 43 and the air supply device and the connection method with the air supply device can refer to the relevant existing technology and will not be repeated here. In addition, the air supply device is not shown in the figure in this embodiment. Further, the driving cylinder 2 43 in this embodiment can also adopt other driving devices that can realize linear telescopic drive, and the installation method of the sand belt correction device 4 can also adopt other installation methods, so as to facilitate the correction of the sand belt 6.

[0097] Further, such as Figure 1 , Figure 2 and Figure 3As shown, the lower end of the fixed support plate 40 in this embodiment is connected to a rotation limit rod 45, which extends horizontally to the right, and the lower end of the rotation support plate 42 is provided with a rotation limit groove 422 opposite to the rotation limit rod 45, and the lower end of the rotation limit groove 422 is open. When the control processing unit controls the driving cylinder 2 43 to drive the push rod 2 to retract, under the pressure of the sanding belt 6 wound around the outer periphery of the sanding belt deviation correction wheel 44, the lower end of the rotation support plate 42 deflects toward the side close to the fixed support plate 40. When the inner top wall of the rotation limit groove 422 on the rotation support plate 42 stops the rotation limit rod 45, the deflection limit position of the lower end of the rotation support plate 42 deflects toward the side close to the fixed support plate 40 is reached, so as to prevent the lower end of the rotation support plate 42 from excessively deflecting toward the side close to the fixed support plate 40.

[0098] Further, such as Figure 1 and Figure 2 As shown, a support driven wheel 101 is installed at the lower front end of the right mounting plate of the mounting seat 1 in this embodiment, and the support driven wheel 101 is specifically installed on the right mounting plate of the mounting seat 1 through the mounting support plate 10, and the mounting support plate 10 is fixedly installed on the right mounting plate of the mounting seat 1 by bolts.

[0099] In this embodiment, if Figure 1 and Figure 2 As shown, the front wheel surface of the support driven wheel 101 in this embodiment is flush with the front wheel surface of the abrasive belt correcting wheel 44, and the abrasive belt 6 respectively passes over the front wheel surface of the support driven wheel 101 and the front wheel surface of the abrasive belt correcting wheel 44. Further, the support driven wheel 101 in this embodiment belongs to the driven wheel, and the reversing support wheel 55 also belongs to the driven wheel. In addition, other driven wheels can be provided as needed.

[0100] An embodiment of the present application, such as Figure 1 , Figure 2 , Figures 4 to 6 As shown, the flexible force-applying driving mechanism includes a flexible force-controlling body and a connecting arm, wherein the flexible force-controlling body is mounted on a mounting seat 1, one end of the connecting arm is connected to the flexible force-controlling body, and the other end of the connecting arm extends away from the flexible force-controlling body to form an extended end, and the force-applying wheel 54 is rotatably mounted on the extended end of the connecting arm;

[0101] The sanding belt edge detection device includes:

[0102] A first photoelectric emitter 561 is disposed on one side of the connecting arm in the vertical direction and on one side of the sanding belt 6 in the horizontal direction, and an emission end of the first photoelectric emitter 561 faces the vertical direction;

[0103] The second photoelectric emitter 562 is arranged parallel to the first photoelectric emitter 561 on one side of the connecting arm in the vertical direction and on the other side of the sanding belt 6 in the horizontal direction, and the emission end of the second photoelectric emitter 562 faces the vertical direction;

[0104] The first photoelectric receiver 571 is arranged on the other side of the connecting arm in the vertical direction, facing the first photoelectric transmitter 561 in the vertical direction, and the receiving end of the first photoelectric receiver 571 faces the transmitting end of the first photoelectric transmitter 561 in the vertical direction;

[0105] The second photoelectric receiver 572 is arranged on the other side of the connecting arm in the vertical direction, facing the second photoelectric transmitter 562 in the vertical direction, and the receiving end of the second photoelectric receiver 572 faces the transmitting end of the second photoelectric transmitter 562 in the vertical direction;

[0106] The first photoelectric transmitter 561, the second photoelectric transmitter 562, the first photoelectric receiver 571, and the second photoelectric receiver 572 are electrically connected to the control processing unit, respectively. The first photoelectric transmitter 561 and the first photoelectric receiver 571 that are arranged opposite to each other detect the deviation of the width edge of the sanding belt 6 to one side in the horizontal direction, and the second photoelectric transmitter 562 and the second photoelectric receiver 572 that are arranged opposite to each other detect the deviation of the width edge of the sanding belt 6 to the other side in the horizontal direction.

[0107] In this embodiment, if Figure 1 , Figure 2 , Figures 4 to 6 As shown, the receiving end of the first photoelectric receiver 571 in the present embodiment is vertically opposite to the transmitting end of the first photoelectric transmitter 561, and the receiving end of the second photoelectric receiver 572 is vertically opposite to the transmitting end of the second photoelectric transmitter 562, so that the displacement of the width edge of the sanding belt 6 to one side in the horizontal direction can be detected by the first photoelectric transmitter 561 and the first photoelectric receiver 571 which are arranged opposite to each other, and the displacement of the width edge of the sanding belt 6 to the other side in the horizontal direction can be detected by the second photoelectric transmitter 562 and the second photoelectric receiver 572 which are arranged opposite to each other, so as to facilitate the detection of the width edges on both sides of the sanding belt 6 and to accurately obtain the displacement of the width edge of the sanding belt 6.

[0108] In this embodiment, if Figure 1 , Figure 2 , Figures 4 to 6As shown, the first photoelectric transmitter 561 emits light to the first photoelectric receiver 571 arranged opposite thereto. When the sanding belt 6 does not block the light emitted by the first photoelectric transmitter 561, the first photoelectric receiver 571 receives the light emitted by the first photoelectric transmitter 561, and the first photoelectric receiver 571 outputs a first signal to the control processing unit. The control processing unit determines that the sanding belt 6 has not shifted to the detection position of the first photoelectric transmitter 561 according to the first signal; and when the sanding belt 6 blocks the light emitted by the first photoelectric transmitter, the first photoelectric receiver 571 cannot receive the light emitted by the first photoelectric transmitter 561, and the first photoelectric receiver 571 outputs a second signal to the control processing unit. The control processing unit determines that the sanding belt 6 has shifted to the detection position of the first photoelectric transmitter 561 according to the second signal, wherein the first signal is different from the second signal, for example, the first signal is a high level, and the second signal is a low level.

[0109] Similarly, the second photoelectric transmitter 562 emits light to the second photoelectric receiver 572 arranged opposite thereto. When the sand belt 6 does not block the light emitted by the second photoelectric transmitter 562, the second photoelectric receiver 572 receives the light emitted by the second photoelectric transmitter 562, and the second photoelectric receiver 572 outputs a third signal to the control processing unit. The control processing unit determines that the sand belt 6 has not shifted to the detection position of the second photoelectric transmitter 562 according to the third signal. When the sand belt 6 blocks the light emitted by the second photoelectric transmitter 562, the second photoelectric receiver 572 cannot receive the light emitted by the second photoelectric transmitter 562, and the second photoelectric receiver 572 outputs a fourth signal to the control processing unit. The control processing unit determines that the sand belt 6 shifts to the detection position of the second photoelectric transmitter 562 according to the fourth signal, wherein the third signal is different from the fourth signal, for example, the third signal is a high level, and the fourth signal is a low level. Thus, the offset position of the sand belt 6 can be detected by the signal conditions output by the first photoelectric receiver 571 and the second photoelectric receiver 572 arranged on both sides of the sand belt 6 to obtain the width edge offset of the sand belt 6. It should be noted that when both sides of the sanding belt 6 do not exceed the allowable offset, it indicates that the sanding belt 6 does not deviate during the transmission process or the offset is within the allowable range. At this time, the first photoelectric receiver 571 and the second photoelectric receiver 572 both output high-level signals.

[0110] An embodiment of the present application, such as Figure 1 , Figure 2 , Figures 4 to 6 As shown, the aircraft engine blade grinding device also includes:

[0111] A first mounting base 56 is arranged on one side of the connecting arm in the vertical direction opposite to the sanding belt 6, and a first photoelectric emitter 561 and a second photoelectric emitter 562 are movably mounted on the first mounting base 56, and a distance between the first photoelectric emitter 561 and the second photoelectric emitter 562 is adjustable;

[0112] The second mounting base 57 is arranged on the other side of the connecting arm in the vertical direction opposite to the first mounting base 56 in the vertical direction. The first photoelectric receiver 571 and the second photoelectric receiver 572 are movably mounted on the second mounting base 57, and the distance between the first photoelectric receiver 571 and the second photoelectric receiver 572 is adjustable.

[0113] In this embodiment, if Figure 5 and Figure 6 As shown, in this embodiment, the first photoelectric transmitter 561 and the second photoelectric transmitter 562 are movably mounted on the first mounting base 56, and the distance between the first photoelectric transmitter 561 and the second photoelectric transmitter 562 is adjustable; in addition, the first photoelectric receiver 571 and the second photoelectric receiver 572 are movably mounted on the second mounting base 57, and the distance between the first photoelectric receiver 571 and the second photoelectric receiver 572 is adjustable; thus, the distance between the first photoelectric transmitter 561 and the second photoelectric transmitter 562 can be adjusted as needed, and the distance between the first photoelectric receiver 571 and the second photoelectric receiver 572 can be adjusted as needed, so that the sanding belt edge detection device is suitable for detecting the offset of the sanding belt 6 with different widths; further, when the offset amount of the sanding belt 6 is allowed to change, the width edge offset of the sanding belt 6 can also be accurately detected by adjusting the distance between the first photoelectric transmitter 561 and the second photoelectric transmitter 562, and adjusting the distance between the first photoelectric receiver 571 and the second photoelectric receiver 572, thereby improving the applicability of the sanding belt edge detection device and meeting different offset detection requirements.
