[0030] In the prior art, a processing component is set on a motion platform, and a fixed trajectory or an auxiliary guidance scheme is used to control the movement of the motion platform to achieve processing. Since some irregular parts cannot be processed through a fixed track, the motion trajectory of the motion platform needs to be constantly modified, which leads to low processing efficiency.
[0031] The utility model provides a motion platform 100, which includes:
[0032] A body 1, a control system 12 is arranged on the body 1, a wheel 11 is rotatably arranged at the bottom of the body 1, and the control system 12 is drivingly connected to the wheel 11;
[0033] A processing assembly 2, wherein the processing assembly 2 is disposed on the main body 1;
[0034] The distance sensor 3 is arranged on the processing component 2, and the distance sensor 3 is connected to the control system 12 by signal. Figure 1 , Figure 1 A represents the horizontal direction, and B represents the vertical direction. Specifically, when processing is required, the motion platform 100 moves to the side of the workpiece to be processed, and the wheels 11 at the bottom of the body 1 have the functions of forward and backward movement, left and right movement, and rotation. The distance sensor 3 on the processing component 2 detects the distance and angle between the current motion platform 100 and the workpiece to be processed, and the distance sensor 3 transmits the measured parameters to the control system 12. The control system 12 analyzes and calculates these parameters, and the control system 12 controls the movement and rotation of the wheels 11, so that the processing component 2 can process the workpiece to be processed. After completing the current processing, the motion platform 100 moves forward. After moving into position, the distance sensor 3 detects the relative position between the motion platform 100 and the workpiece to be processed again, and continues to transmit the currently detected distance and angle between the motion platform 100 and the workpiece to be processed to the control system 12. The control system 12 analyzes and calculates these parameters to control the operation of the wheels 11, and so on and so forth until all processing is completed. The technical solution of this embodiment connects the distance measuring sensor 3 with the control system 12 signal and drives the wheel 11 to move, so that the motion platform 100 can move along the contour of the workpiece to be processed and process it at the same time, thereby greatly expanding the processing range. In addition, there is no need to set the motion trajectory of the motion platform 100 before the operation, and there is no need to redefine the motion trajectory during the processing operation when there is a deviation in the placement position of the workpiece to be processed or a size difference in the contour of the workpiece to be processed. This reduces the labor intensity of the operators and greatly improves the processing efficiency of the motion platform 100.
[0035] In one embodiment, the processing assembly 2 includes a processing component 21 and a sliding component 22. The sliding component 22 is slidably installed on the main body 1 in the vertical direction, and the processing component 21 is arranged on the sliding component 22. Since the heights of different types of workpieces to be processed are different, and there may be height differences at different positions of an irregular workpiece to be processed, different heights at the same position may also have different profiles; therefore, when processing, the distance sensor 3 on the processing assembly 2 detects the distance and angle between the current motion platform 100 and the workpiece to be processed, and the distance sensor 3 transmits the measured parameters to the control system 12. The control system 12 analyzes and calculates these parameters, and the control system 12 controls the wheel 11 to move and rotate, so that the processing component 21 can process the workpiece to be processed. After completing the current processing, the control system 12 controls the sliding component 22 to move upward on the main body 1 in the vertical direction. After moving into position, the distance sensor 3 The relative position between the motion platform 100 and the workpiece to be processed is detected again, and the distance and angle between the motion platform 100 and the workpiece to be processed currently detected are continuously transmitted to the control system 12. The control system 12 controls the wheel 11 to run by analyzing and calculating these parameters, and repeats this process until the full-height processing at this position is completed. When the full-height processing of the workpiece to be processed at this position is completed, the wheel 11 is controlled to move forward, and then the above steps are repeated. The sliding component 22 is slidably installed on the main body 1 in the vertical direction, so that the height of the processing component 21 can be adjusted to realize the full-height processing of the workpiece to be processed, and the processing of different heights of the workpiece to be processed can be realized, thereby further expanding the processing range of the processing component 21.
[0036] In one embodiment, the processing assembly 2 further includes a processing component 21 , a sliding component 22 and a connecting plate 23 , the connecting plate 23 is rotatably mounted on the body 1 , the sliding component 22 is slidably mounted on the connecting plate 23 along a vertical direction, and the processing component 21 is disposed on the sliding component 22 . Specifically, when processing is required, the motion platform 100 moves to the side of the workpiece to be processed, and the wheel 11 at the bottom of the body 1 has the functions of forward and backward movement, left and right movement and rotation. The distance sensor 3 on the processing component 2 detects the distance and angle between the current motion platform 100 and the workpiece to be processed, and the distance sensor 3 transmits the measured parameters to the control system 12. The control system 12 analyzes and calculates these parameters, and the control system 12 controls the wheel 11 to move and rotate, and controls the connection plate 23 to rotate, so that the processing end of the processing component 21 can be set toward the workpiece to be processed, so that the processing component 21 can process the workpiece to be processed. After completing the current processing, the motion platform 100 moves forward, and after moving into position, the distance sensor 3 detects the relative position between the motion platform 100 and the workpiece to be processed again, and continues to transmit the distance and angle between the currently detected motion platform 100 and the workpiece to be processed to the control system 12. The control system 12 analyzes and calculates these parameters, controls the wheel 11 to run, and controls the connection plate 23 to rotate, and so on, until all processing is completed. By setting the connection plate 23 rotatably installed on the body 1, the angle adjustment of the processing component 21 can be achieved.

Specifically, an irregular workpiece to be processed may have a concave situation. In order to ensure that the processing component 21 can be processed in the concave position, the processing component 21 is slidably mounted on the sliding subcomponent 222. During processing, the distance sensor 3 on the processing component 21 detects the distance and angle between the current motion platform 100 and the workpiece to be processed. The distance sensor 3 transmits the measured parameters to the control system 12. The control system 12 analyzes and calculates these parameters, and the control system 12 controls the wheel 11 to move and rotate. When the processing component 21 cannot process the groove, the processing component 21 is controlled to slide and extend toward the workpiece to be processed in the horizontal direction, so that the processing component 21 can process the workpiece to be processed; by sliding the processing component 21 in the horizontal direction on the sliding subcomponent 222, the extended length of the processing component 21 can be adjusted, and the processing range of the processing component 21 can be further expanded.

[0041] In one embodiment, the number of the distance measuring sensors 3 is at least four, wherein two distance measuring sensors 3 are respectively arranged on both sides of the processing head 211, wherein the other two distance measuring sensors 3 are respectively arranged at the top and bottom of the processing head 211.
