[0058] Referring to FIGS. 1 to 4 , the present application provides a dust and rust removal machine for bearing cover mark plates and bolts of a wheel axle production line, which are referred to as dust and rust removal machines in this article. The dust and rust removal machine includes a main body base 1000, a positioning device 2000, a first cleaning device 3000 and a second cleaning device 4000. The positioning device 2000 is arranged on the main body base 1000, and the positioning device 2000 is used to position the target wheel pair 100 to be cleaned on the main body base 1000. Therefore, before cleaning the target wheel pair 100, the positioning device 2000 can be used to position the target wheel pair 100 on the main body base 1000, so that the target wheel pair 100 is in a position and angle suitable for the first cleaning device 3000 and the second cleaning device 4000 to perform cleaning operations. Those skilled in the art can set the position and angle of the target wheel pair 100 on the main body base 1000 to be a suitable position and angle according to actual needs, which is not limited here.

[0059] 5 and 6, the target wheel set 100 includes two wheel bodies, which are symmetrically mounted at both ends of the central axis, and then the two wheel bodies are combined through a central axis to form the target wheel set 100. The outer wall of each wheel body is provided with a sign plate and a bolt, and the sign plate and the bolt are the target objects that need to be cleaned by the dust and rust removal machine provided by the self.

[0060] In one embodiment, the area for cleaning of the first cleaning device 3000 is defined as a first target cleaning area 110, and the first target cleaning area 110 is defined as at least a portion of the surface area of ​​the sign board of the target wheel pair 100, that is, the first cleaning device 3000 can be used to clean a portion of the sign board, such as the central area, or the first target cleaning area 110 can be adjusted to other area positions or area areas of the sign board as required, which is not limited here.

[0061] At the same time, the area in which the second cleaning device 4000 is configured to be cleaned is defined as the second target cleaning area 120. The second target cleaning area 120 is at least a partial surface area of ​​the bolts of the target wheelset 100, and the bolts protrude from the surface of the sign plate. For example, the second cleaning device 4000 can be used to clean surface areas such as the bolt head of the bolt, or the second target cleaning area 120 can be adjusted to other area positions or area areas of the bolt as required, which is not limited here.

[0062] As shown in Fig. 5 and Fig. 6, the number of the second target cleaning areas 120 is configured to be several, that is, the number of bolts set on the wheel body of the target wheelset 100 is several, and the several second target cleaning areas 120 are distributed around the first target cleaning area 110. For example, several bolts are set on the sign plate, so that when the sign plate is fixed to the target wheelset 100 by the several bolts, the several bolts are distributed around the circumference of the sign plate. At this time, the first target cleaning area 110 is defined as the central area on the sign plate, and the central area is also the area surrounded by the several bolts on the sign plate. Therefore, the several second target cleaning areas 120 are the surfaces of the bolt heads of the several bolts.

[0063] Continuing to refer to FIG. 1 and FIG. 3 , the first cleaning device 3000 is movably mounted on the main body base 1000, wherein the movability of the first cleaning device 3000 relative to the main body base 1000 includes but is not limited to the first cleaning device 3000 being able to move in a three-dimensional space in the height direction, left-right direction, and front-back direction relative to the main body base 1000, so as to be able to move to any position within a specific three-dimensional space. The movability of the first cleaning device 3000 relative to the main body base 1000 can be achieved by using guide mechanisms such as height direction tracks, left-right direction tracks, and front-back direction tracks. In addition, it is not limited to being achieved by using other driving mechanical mechanisms such as multi-joint drive arms, hinge mechanisms, and screw mechanisms, and is not limited here.

[0064] The first cleaning device 3000 includes a first device base 3100, a first driving device 3200 and a first cleaning assembly 3300, and the first driving device 3200 and the first cleaning assembly 3300 are assembled on the first device base 3100. The first cleaning assembly 3300 includes a first cleaning brush body 3310 and a brush body assembly cylinder 3320, the first cleaning brush body 3310 is assembled in the cylinder cavity of the brush body assembly cylinder 3320, and part of the brush body structure of the first cleaning brush body 3310 is exposed at one cylinder end of the brush body assembly cylinder 3320, and the exposed length can be adjusted according to demand, as long as the exposed length is guaranteed to meet the cleaning of the first target cleaning area 110.

[0065] Among them, the inner diameter of the brush assembly tube 3320 can be set to about 35mm, the outer diameter of the brush assembly tube 3320 can be set to about 37mm, and the length of the first cleaning brush body 3310 can be set to about 25mm. Alternatively, in one embodiment, the brush assembly tube 3320 can have an elastic telescopic function, for example, the brush assembly tube 3320 can be formed by two or more unit tubes that are elastically sleeved together, or the brush assembly tube 3320 can also achieve an elastic telescopic function through elastic materials such as rubber. Therefore, the length of the first cleaning brush body 3310 assembled in the brush assembly tube 3320 can also be set to be the same. When working, the first cleaning brush body 3310 assembled in the brush assembly tube 3320 is in contact with the first target cleaning area 110. Based on the elastic telescopic function of the brush assembly tube 3320, part of the brush body structure of the first cleaning brush body 3310 can be exposed at one end of the brush assembly tube 3320.

[0066] The first driving device 3200 is drivingly connected to the first cleaning component 3300. The first driving device 3200 can adopt various models or types of motors, for example. The first driving device 3200 is used to drive the first cleaning component 3300 to rotate relative to the first device base 3100. The rotation of the first cleaning component 3300 includes various rotations including fixed-axis rotation, as long as the cleaning requirements of the first target cleaning area 110 are met. Therefore, the first cleaning component 3300 can be used to clean the first target cleaning area 110 of the target wheel pair 100 through its own rotation.

[0067] Continuing to refer to FIG. 2 and FIG. 4 , the second cleaning device 4000 is movably mounted on the main body base 1000, wherein the movability of the second cleaning device 4000 relative to the main body base 1000 includes but is not limited to the second cleaning device 4000 being able to move in a three-dimensional space in the height direction, left-right direction, and front-back direction relative to the main body base 1000, so as to be able to move to any position within a specific three-dimensional space. The movability of the second cleaning device 4000 relative to the main body base 1000 can be achieved by using guide mechanisms such as height direction tracks, left-right direction tracks, and front-back direction tracks. In addition, it is not limited to being achieved by using other driving mechanical mechanisms such as multi-joint drive arms, hinge mechanisms, and screw mechanisms, and is not limited here.

[0068] The second cleaning device 4000 includes a second device base 4100, a second drive device 4200 and a second cleaning assembly 4300, and the second drive device 4200 and the second cleaning assembly 4300 are assembled on the second device base 4100. Among them, the second cleaning assembly 4300 includes a second cleaning brush body 4310 and a brush body assembly seat 4320, and the second cleaning brush body 4310 is assembled on the brush body assembly seat 4320. The second drive device 4200 is drivingly connected to the second cleaning assembly 4300, and the second drive device 4200 can be, for example, a motor of various models or types, and the second drive device 4200 is used to drive the second cleaning assembly 4300 to rotate relative to the second device base 4100. The rotation of the second cleaning assembly 4300 includes various rotations including fixed axis rotation, as long as the cleaning demand for the second target cleaning area 120 is met, and thus, the second cleaning assembly 4300 can be used to clean the second target cleaning area 120 of the target wheel pair 100 by its own rotation.

[0069] The second cleaning brush body 4310 can be set as a ring-shaped brush body. For example, the outer diameter of the second cleaning brush body 4310 can be set to about 135 mm, the inner diameter of the second cleaning brush body 4310 can be set to about 50 mm, and the length of the second cleaning brush body 4310 can be set to about 35 mm.

[0070] Continuing to refer to Figures 1 to 4, the main body base 1000 serves as an assembly basis for devices such as the positioning device 2000, the first cleaning device 3000 and the second cleaning device 4000. The main body base 1000 can be adaptively constructed according to the number, structure and other aspects of the positioning device 2000, the first cleaning device 3000 and the second cleaning device 4000. For example, as shown in Figures 1 and 2, when the number of the first cleaning device 3000 and the second cleaning device 4000 is set to two, the main body base 1000 can include a base located in the middle and two columns located at the left and right ends of the base, and the two columns are symmetrically arranged on the base.

[0071] Based on the structure of the main base 1000 provided in the above embodiment, the positioning device 2000 can be set on the base in the middle of the main base 1000, so that the target wheel pair 100 can be positioned and set on the base through the positioning device 2000, and the two ends of the target wheel pair 100 can correspond to the two columns on the left and right ends of the base respectively. Correspondingly, the two first cleaning devices 3000 and the second cleaning devices 4000 can be respectively set on the two columns on the left and right ends of the base, that is, each column is movably equipped with a first cleaning device 3000 and a second cleaning device 4000, so that both ends of the target wheel pair 100 can implement the cleaning operations of the first target cleaning area 110 and the second target cleaning area 120 through the first cleaning devices 3000 and the second cleaning devices 4000 on their respective corresponding columns.

[0072] As shown in Figures 7 and 8, after the target wheel pair 100 is positioned on the main base 1000, the first cleaning device 3000 can move relative to the main base 1000 based on its movable assembly on the main base 1000, and then move to a position corresponding to the first target cleaning area 110 of the target wheel pair 100. At this time, the first driving device 3200 of the first cleaning device 3000 can drive the first cleaning component 3300 to rotate, and the first target cleaning area 110 is cleaned by the first cleaning brush body 3310 of the first cleaning component 3300.

[0073] In one embodiment, the first driving device 3200 drives the first cleaning assembly 3300 to rotate along the first rotation axis, that is, the first cleaning brush body 3310 of the first cleaning assembly 3300 cleans the first target cleaning area 110 by rotating along the first rotation axis. In addition, the first cleaning device 3000 may also include a composite driving assembly, which is assembled on the first device base 3100. In this case, the first driving device 3200 is indirectly assembled on the first device base 3100 through the composite driving assembly, and the composite driving assembly can be used to drive and connect with the first driving device 3200.

[0074] Since the first drive device 3200 is drivenly connected to the first cleaning component 3300, the composite drive component can be used to drive the first drive device 3200 and the first cleaning component 3300 to rotate synchronously along the first rotation axis, wherein the rotational speed at which the composite drive component drives the first drive device 3200 and the first cleaning component 3300 to rotate synchronously along the first rotation axis is limited to a first rotational speed, and the rotational speed at which the first drive device 3200 drives the first cleaning component 3300 to rotate along the first rotation axis is a second rotational speed. At this time, it is necessary to limit the first rotational speed to be less than the second rotational speed.

[0075] Because the purpose of the composite drive assembly driving the first drive device 3200 and the first cleaning assembly 3300 to rotate synchronously with a fixed axis is to rotate in the circumferential direction, and the purpose of the first drive device 3200 driving the first cleaning assembly 3300 to rotate with a fixed axis is to press the first cleaning brush body 3310 against the target wheel pair 100 through high-speed rotation to achieve a cleaning operation on the first target cleaning area 110. Therefore, the first rotation speed can be several or dozens of times smaller than the second rotation speed according to the needs, and is not limited here.

[0076] At the same time, the composite drive assembly is used to drive the first drive device 3200 and the first cleaning assembly 3300 to reciprocate along the first motion trajectory, and the first motion trajectory is not parallel to the first rotation axis, for example, the first motion trajectory forms a suitable angle with the first rotation axis in space. Therefore, through the synchronous driving of the first drive device 3200 and the first cleaning assembly 3300 by the composite drive assembly, the first drive device 3200 and the first cleaning assembly 3300 can be simultaneously controlled to superimpose two different motion states, so that the first drive device 3200 and the first cleaning assembly 3300 can simultaneously rotate circumferentially and reciprocate radially, and in this process, the first cleaning assembly 3300 will also be controlled by the first drive device 3200 to be a rotation state of fixed axis rotation, and the rotation state of fixed axis rotation does not interfere with the superimposed motion of the above-mentioned superimposed simultaneous circumferential rotation and radial reciprocating motion, so that the entire actual motion presents a composite motion of two fixed axis rotations and reciprocating motions at different speeds.

[0077] In one embodiment, the first motion trajectory is in a plane, and the first rotation axis is perpendicular to the plane where the first motion trajectory is located. In this case, the first motion trajectory can be presented as a curved motion in the plane. Alternatively, the first motion trajectory is a linear trajectory, and the first rotation axis is perpendicular to the first motion trajectory. The composite drive component drives the first cleaning component 3300 to reciprocate along the first motion trajectory. In this case, the actual motion of the first cleaning component 3300 is presented as a composite motion of fixed-axis rotation and reciprocating linear motion.

[0078] Moreover, in one embodiment, the composite drive assembly may include a third drive device and a fourth drive device. For example, the third drive device may be used to drive the first drive device 3200 and the first cleaning assembly 3300 to rotate synchronously along the first rotation axis, wherein the speed at which the third drive device drives the first drive device 3200 and the first cleaning assembly 3300 to rotate synchronously along the first rotation axis is defined as the first speed, and the speed at which the first drive device 3200 drives the first cleaning assembly 3300 to rotate along the second speed, and in this case, the first speed needs to be defined as less than the second speed. At the same time, the fourth drive device is used to drive the first drive device 3200 and the first cleaning assembly 3300 to reciprocate along the first motion trajectory.

[0079] In this embodiment, the third drive device and the fourth drive device can be both mounted on the first device base 3100. At this time, the third drive device is drivingly connected to the first drive device 3200, and the fourth drive device is drivingly connected to the third drive device. The third drive device is indirectly mounted on the first device base 3100 through the fourth drive device, and the first drive device 3200 is indirectly mounted on the first device base 3100 through the third drive device and the fourth drive device. The third drive device drives the first drive device 3200 and the first cleaning assembly 3300 to rotate synchronously with a fixed axis, and the fourth drive device is used to drive the third drive device, the first drive device 3200 and the first cleaning assembly 3300 to reciprocate synchronously.

[0080] Referring to Figures 7 and 8, when the first cleaning component 3300 performs a cleaning operation on the first target cleaning area 110 by rotating on a fixed axis, the third driving device drives the first driving device 3200 and the first cleaning component 3300 to rotate on a fixed axis synchronously, so that the first driving device 3200 and the first cleaning component 3300 rotate circumferentially at a slower first speed. At the same time, the fourth driving device drives the third driving device, the first driving device 3200 and the first cleaning component 3300 to reciprocate synchronously, so that the third driving device, the first driving device 3200 and the first cleaning component 3300 reciprocate synchronously along the radial direction.

[0081] This control method can make the first cleaning component 3300 have three superimposed motion states. The first motion state is that the first cleaning component 3300 rotates at a faster first speed to perform a cleaning operation on the first target cleaning area 110. The second motion state is that the first cleaning component 3300 rotates circumferentially at a slower first speed. The third motion state is that the first cleaning component 3300 reciprocates radially. Therefore, the first cleaning component 3300 can continuously change the contact position in the first target area under the superimposed effect of the second motion state and the third motion state, fully clean the first target cleaning area 110, and increase the cleaning area of ​​the first target cleaning area 110.

[0082] Since the first cleaning component 3300 can continuously change the contact position in the first target area under the superposition of the second motion state and the third motion state. Therefore, in the above control method, the reciprocating linear motion of the first cleaning component 3300 along the first motion trajectory is limited to reciprocating linear motion only in the first target cleaning area 110. This limitation can be limited by program or by physical contact. For example, in one embodiment, there is an isolation gap 130 between adjacent second target cleaning areas 120, and the gap width of the isolation gap 130 is smaller than the diameter of the brush body assembly cylinder 3320. Therefore, when the brush body assembly cylinder 3320 contacts the bolts of the second target cleaning area 120, the bolts will restrict the brush body assembly cylinder 3320, and the smaller gap width of the isolation gap 130 can be used to prohibit the brush body assembly cylinder 3320 from passing through. Therefore, the brush body assembly cylinder 3320 can only be limited in the first target cleaning area 110, thereby limiting the first cleaning component 3300 to move only in the first target cleaning area 110.

[0083] In addition, when there is an isolation gap 130 between adjacent second target cleaning areas 120, the gap width of the isolation gap 130 can also be limited to be greater than or equal to the diameter of the brush assembly cylinder 3320, thereby allowing the brush assembly cylinder 3320 to pass through, so the brush assembly cylinder 3320 can also be allowed to enter the isolation gap 130 between adjacent second target cleaning areas 120 to clean the area and expand the cleaning range. Among them, the gap width of the isolation gap 130 can be limited to 45mm.

[0084] Those skilled in the art can select a suitable method to set the relationship between the gap width of the isolation gap 130 and the diameter of the brush assembly tube 3320 according to actual needs, thereby achieving different cleaning effects, which is not limited here.

[0085] During this process, since the first cleaning brush body 3310 is located in the brush body assembly tube 3320 , the first cleaning brush body 3310 will not be rolled onto the bolts of the second target cleaning area 120 when cleaning the first target cleaning area 110 .

[0086] In addition, in one embodiment, the first cleaning device 3000 may further include a resistance sensor and a first controller. The resistance sensor is arranged on the first device base 3100, and the resistance sensor is connected to the first cleaning component 3300, and the resistance sensor is used to obtain the motion resistance information of the first cleaning component 3300 when the first cleaning component 3300 reciprocates along the first motion trajectory. The first controller is connected to the resistance sensor and the composite drive component, and the first controller is used to generate motion control information according to the motion resistance information, and the first controller is used to control the composite drive component to drive the first drive device 3200 and the first cleaning component 3300 according to the motion control information. Thus, the first cleaning component 3300 can be actively controlled to move only in the first target cleaning area 110 through the data and control cooperation of the resistance sensor and the first controller.

[0087] In one embodiment, the motion resistance information includes a real-time resistance value, and the reciprocating linear motion of the first cleaning component 3300 along the first motion trajectory includes a positive linear motion and a reverse linear motion in opposite directions. The motion of the first cleaning component 3300 from the first target cleaning area 110 toward the second target cleaning area 120 is a positive linear motion, that is, the bolt motion radially from the central position of the mark plate toward the periphery shown in FIG6 , on the contrary, the motion of the first cleaning component 3300 from the second target cleaning area 120 toward the first target cleaning area 110 is a reverse linear motion.

[0088] The real-time resistance value can represent the real-time resistance experienced by the first cleaning component 3300. When the first cleaning component 3300 is not in contact with the bolt, the resistance experienced by the first cleaning component 3300 is small, mainly from the friction experienced by the first cleaning component 3300 when cleaning the first target cleaning area 110. However, when the real-time resistance value is greater than or equal to the preset resistance peak value, it means that the resistance experienced by the first cleaning component 3300 becomes larger, not only from the friction experienced by the first cleaning component 3300 when cleaning the first target cleaning area 110, but also mainly indicates that the first cleaning component 3300 is in contact with the bolt, and the bolt prohibits the first cleaning component 3300 from continuing radial movement. At this time, the first controller is used to control the composite drive component to drive the first drive device 3200 and the first cleaning component 3300 according to the motion control information, so that the composite drive component drives the first drive device 3200 and the first cleaning component 3300 that are in forward linear motion to simultaneously perform reverse linear motion in the opposite direction.

[0089] In one embodiment, the dust and rust removal machine includes a moving base 5000, which is movably assembled on a main base 1000. The main base 1000 defines a first reference plane and a second reference plane, and the first reference plane and the second reference plane are perpendicular to each other, wherein the first reference plane can be used to represent a reference plane parallel to the horizontal plane, and the second reference plane can be used to represent a reference plane perpendicular to the horizontal plane (or parallel to the vertical plane).

[0090] The positioning device 2000 is used to position the target wheelset 100 to a state where the central axis of the target wheelset 100 is parallel to both the first reference plane and the second reference plane, that is, the central axis of the target wheelset 100 is parallel to both the horizontal plane and the vertical plane, and the motion base 5000 is used to move in a plane parallel to the second reference plane, that is, the motion base 5000 performs planar motion perpendicular to the horizontal plane (or parallel to the vertical plane) and performs height movement.

[0091] The dust and rust removal machine also includes a first linear rail 5100 and a second linear rail 5200, and a matching third linear rail (not shown) and a fourth linear rail (not shown). The first cleaning device 3000 is assembled on the motion base 5000 through the first linear rail 5100 and the third linear rail. The first linear rail 5100 is parallel to the first reference plane, and the first linear rail 5100 is perpendicular to the second reference plane. The third linear rail is perpendicular to the first linear rail. The first cleaning device 3000 reciprocates along the first linear rail 5100, and the third linear rail reciprocates along the first linear rail 5100. At this time, the first cleaning device 3000 can move forward and backward and left and right in three-dimensional space based on the first linear rail 5100 and the third linear rail, thereby approaching or moving away from the target wheel pair 100.

[0092] The second cleaning device 4000 is assembled on the motion base 5000 through the second linear rail 5200 and the fourth linear rail. The second linear rail 5200 is parallel to the first reference plane, and the second linear rail 5200 is perpendicular to the second reference plane. The fourth linear rail is perpendicular to the second linear rail 5200. The second cleaning device 4000 moves back and forth along the second linear rail 5200, and the fourth linear rail moves back and forth along the second linear rail 5200. At this time, the second cleaning device 4000 can move back and forth and left and right in three-dimensional space based on the second linear rail 5200 and the fourth linear rail, thereby approaching or moving away from the target wheel pair 100.

[0093] In one embodiment, the dust and rust removal machine includes a positioning device 5300 and a second controller. The positioning device 5300 is disposed on the motion base 5000, and the positioning device 5300 is used to positionally contact with the target wheel pair 100 to be cleaned, and the positioning device 5300 generates positioning contact information when positioning contact with the target wheel pair 100. For example, the positioning device 5300 may also use a contact sensor, and when the positioning device 5300 is in positioning contact with the target wheel pair 100, it indicates that the motion base 5000 has moved to the right position. The second controller is connected to the positioning device 5300 and the moving base 5000. The second controller is used to control the moving base 5000 to move in a plane parallel to the second reference plane according to the positioning contact information. For example, when the positioning contact information indicates that the moving base 5000 has moved into place, the second controller stops the movement of the moving base 5000. Otherwise, it continues to move in a preset direction, so that the moving base 5000 moves to a preset target position, and aligns the first cleaning device 3000 and the second cleaning device 4000 with the target wheel pair 100 to prepare for the cleaning operation.

[0094] In one embodiment, the positioning device 2000 includes a moving component 2100 and a fixed component 2200, the moving component 2100 is assembled on the main body base 1000, and the moving component 2100 reciprocates on the main body base 1000 along the wheelset translation trajectory, the wheelset translation trajectory is a straight line trajectory, wherein the wheelset translation trajectory is parallel to the first reference plane, and the wheelset translation trajectory is perpendicular to the second reference plane, and the wheelset translation trajectory is parallel to the central axis of the target wheelset 100. The fixed component 2200 is arranged on the moving component 2100, and the fixed component 2200 is used to fix the target wheelset 100 to be cleaned.

[0095] As can be seen from the above, the dust and rust removal machine includes a first cleaning device 3000 and a second cleaning device 4000. The first cleaning device 3000 performs rust removal on the sign plate area, and the second cleaning device 4000 performs rust removal on the bolts. Moreover, the first cleaning device 3000 and the second cleaning device 4000 have a mobile operation function, can be self-positioned according to the height of the wheelset, can adapt to the positioning dimensions of different wheelset heights, and adopt a method of switching the cleaning device positions to ensure that the first cleaning device 3000 and the second cleaning device 4000 can be aligned with the center axis of the wheelset, compatible with automatic rust removal of different wheelsets and different bolt positions, and can maximize the rust removal area, thereby automatically completing the dust and rust removal of the sign plate and the bolts.
