Description

Technical Field

[0001] This invention relates to the field of surface treatment systems, and in particular to a surface treatment system based on electromagnetic wave monitoring. Background Technology

[0002] Shot peening is a widely used surface strengthening process in factories. It involves bombarding the surface of a workpiece with shot to implant residual compressive stress, thereby improving the workpiece's fatigue strength. It is widely used to improve the mechanical strength, wear resistance, fatigue resistance, and corrosion resistance of parts.

[0003] Shot peening is required in the machining of automotive parts to improve their surface quality. Currently, shot peening typically involves suspending the parts inside a peening chamber and then blasting shot through a nozzle to clean the surface. However, existing shot peening equipment often has fixed nozzles, resulting in a fixed contact point between the shot and the part surface. This makes it difficult to achieve a comprehensive and uniform cleaning, and the dust within the peening chamber can also negatively impact the surface treatment quality. Therefore, a surface treatment system based on electromagnetic wave monitoring is needed. Summary of the Invention

[0004] The present invention addresses the technical problem of improving the surface treatment quality of parts by a surface treatment system, and provides a surface treatment system and control method based on electromagnetic wave monitoring.

[0005] The technical solution adopted by this invention to solve its technical problem is: A surface treatment system based on electromagnetic wave monitoring includes: a housing; a part clamping structure disposed inside the housing, the upper end of the part clamping structure being rotatably connected to the inner top of the housing, and the lower end being connected to a part, the rotation axis of the part clamping structure being vertically oriented; a shot peening structure disposed on the side of the housing, the shot peening structure being connected to a plurality of transverse shot peening nozzles and a plurality of shot peening heads; and a plurality of transverse shot peening nozzles disposed inside the housing, located on the inner sidewall of the housing, the plurality of transverse shot peening nozzles being uniformly arranged vertically, the transverse shot peening nozzles facing the rotation axis of the part clamping structure. The system includes several transverse shot peening nozzles connected to the shot peening structure; several rotating shot peening devices, each mounted on the inner wall of the housing, located to the side of the transverse shot peening nozzles, evenly arranged vertically, and cooperating with the parts; each rotating shot peening device includes: a rotating shaft, which is transversely fixed to the inner wall of the housing via a support frame; a first gear, the center of which is fitted onto the rotating shaft, and the first gear and the rotating shaft are rotatably connected via bearings; a forward and reverse rotating motor, located outside the first gear, with the rotation axis of the forward and reverse rotating motor parallel to the axis of the first gear; and a second gear. The second gear is fixed to the rotating shaft of the reversible motor, with its side center fixed to the outside of the first gear. The second gear meshes with the first gear. A tubular shot peening head is fixed to the side of the second gear, with one end facing the workpiece and the other end connected to the shot peening mechanism via a pipe. A protective structure covers the outside of the first gear, second gear, reversible motor, and shot peening head, cooperating with the rotation of the shot peening head. A recovery structure is located on the side of the housing, with one end connected to the shot peening structure and the other end connected to the bottom of the inner side of the housing. A dust removal device is also included. The system comprises: a housing containing several infrared radars; an intelligent processor mounted on the housing and connected to the infrared radars; a memory mounted on the housing and connected to both the infrared radars and the intelligent processor; a controller mounted on the housing and connected to the intelligent processor, several transverse shot peening nozzles, several rotating shot peening devices, and a part clamping structure; and a display mounted on the housing and connected to the intelligent processor. The rotating shot peening devices and the transverse shot peening nozzles are not arranged opposite each other. The protective structure works in conjunction with the rotation of the shot peening head, without obstructing its rotation.

[0006] The parts are fixed in the center of the housing by a part clamping structure. The rotation of the clamping structure causes the parts to rotate, cooperating with several transverse shot peening nozzles to polish the parts. Several infrared radars are set on the inner wall of the housing to scan the parts and record their surface conditions. After the transverse shot peening nozzles polish the parts, the intelligent processor compares the initial surface data of the parts with the current surface data to obtain the polished thickness at various points on the part surface. If the polished thickness does not meet the standard, several shot peening heads are used to target the parts on the part surface that do not meet the polishing standard. If the effective surface of the part disappears after polishing, its function will also be damaged. At this time, an alarm will be issued through the display, and the shot peening machine will be inspected and repaired. The shot and dust fall to the bottom of the housing. The dust is cleaned by the dust removal device and then returned to the shot peening structure for recycling by the recycling structure. Since the parts have already been polished by the transverse shot peening nozzles, the surfaces that do not meet the standard polished thickness are those whose normal direction is not transverse, and these surfaces need to be polished by the vertically inclined shot peening nozzles. Driven by a reversible motor, the second gear rotates, which in turn drives the first gear to rotate, causing the shot peening head to rotate. Several vertically aligned shot peening heads, intersecting at a single point, can produce shot peening at different angles from the same point, improving the surface polishing quality of the parts. Several infrared radars are installed to monitor the part surface. Several horizontal shot peening nozzles and heads are provided for comprehensive and uniform cleaning of the part surface. A memory is included to store data processed by the intelligent processor, part surface data, and data from all effective surfaces of the part. A part clamping structure is provided to secure the part. A dust removal device is installed to remove dust from the shot and the interior of the casing. A protective structure is provided to prevent the shot from damaging the rotating shot peening device.

[0007] Furthermore, the dust removal device includes: a blower, which is located at the top inside the housing; a suction fan, which is located at the bottom inside the housing, below the part; a first dust filter, which is located inside the housing, above the suction fan, below the part, below several transverse shot peening nozzles, and below several rotating shot peening devices. The mesh diameter of the first dust filter is smaller than the diameter of the shot. The first dust filter is inclined towards the connection between the housing and the recovery structure, and the lower end of the first dust filter matches the connection between the housing and the recovery structure; and a shaking structure. Inside the housing, its side is connected to the inner wall of the housing. The shaking structure is located above the first dust filter and below the part. The shaking structure is positioned below several transverse shot peening nozzles and below several rotating shot peening devices. The shaking structure is inclined in the opposite direction to the inclination direction of the first dust filter. The shaking structure includes a filter screen, which is located inside the housing, above the first dust filter and below the part. The filter screen is positioned below several transverse shot peening nozzles and below several rotating shot peening devices. The filter screen is inclined in the opposite direction to the inclination direction of the first dust filter. The mesh diameter of the filter screen is adapted to the diameter of the shot. The lower end of the first dust filter and the connection port between the housing and the recovery structure cooperate to enable the recovery structure to recover the shot.

[0008] The shot blasting material falls onto the filter screen, accumulates to one side due to the inclined surface, and passes through the mesh of the filter screen under the action of the shaking structure, leaving behind larger dust particles. The shot then falls onto the first dust filter screen, rolls to one side under the action of the inclined surface, and during the rolling process, dust passes through the mesh of the first dust filter screen, ultimately allowing the shot to be recovered by the recycling structure. The blower blows outside air into the housing from top to bottom, carrying away the dust from the shot blasting area. Then, most of the airflow passes through the mesh at the top of the filter screen and enters the lower part, while a small portion passes through the shot accumulated at the bottom of the filter screen and enters the lower part. Finally, the airflow enters the suction fan for purification and is discharged into the outside air. If both the first and second filters are horizontally set, the shot will spread evenly on their surfaces. The airflow carrying dust will need to pass through two layers of shot before entering the suction fan, which will affect the dust removal efficiency and cause the clean shot to absorb dust. Therefore, a mechanism is needed that allows the airflow carrying dust directly into the suction fan. The first dust filter and the filter screen are tilted to move the shot to one side, exposing part of the first dust filter and part of the filter screen. The first dust filter is tilted towards the connection between the housing and the recovery structure to improve the recovery effect of the recovery structure. The filter screen is tilted in the opposite direction to the tilt of the first dust filter, so that the shot falling from the filter screen needs to roll for a period of time, which is beneficial for cleaning the dust on the shot surface in coordination with the airflow. Since large particles such as rust and part dust also fall onto the filter screen, they can easily clog the mesh, reduce the speed at which the shot falls from the filter screen, and easily cause accumulation. Therefore, shaking is necessary. The shaking structure is designed to prevent shot from accumulating on the filter screen, clogging the shot blasting nozzle, and affecting the shot blasting process. It can also coordinate with the airflow to improve dust removal efficiency. The shaking structure also prevents shot from covering the top of the filter screen, thus preventing airflow obstruction.

[0009] Furthermore, the shaking structure includes: an elliptical ring disposed inside the housing, the elliptical ring tilting in the opposite direction to the tilting direction of the first dust filter, its side tightly connected to the inner wall of the housing, the elliptical ring located above the first dust filter and below the parts, the elliptical ring positioned below several transverse shot peening nozzles and several rotating shot peening devices, a sliding groove provided on the inner side of the elliptical ring, the sliding groove being annular, the sliding groove engaging with the elliptical ring, a reciprocating moving structure provided inside the upper end of the sliding groove, the axis of the moving end of the reciprocating moving structure coinciding with the tilting direction of the elliptical ring; a filter screen disposed inside the elliptical ring, located within the sliding groove, the filter screen engaging with the sliding groove, the filter screen being movable within the sliding groove, the upper end of the filter screen connected to the reciprocating moving structure, the upper surface of the filter screen being wavy. The engagement of the sliding groove with the elliptical ring allows the filter screen to be placed into the sliding groove. The engagement of the filter screen with the sliding groove allows the filter screen to slide within the sliding groove without its edges detaching from the sliding groove. The elliptical ring can be removed from the housing.

[0010] A reciprocating moving structure drives the filter screen to move back and forth within a sliding groove, creating a vibration effect. The sliding groove prevents dust from falling directly to the bottom without passing through the filter screen. The reciprocating moving structure allows the filter screen to move back and forth, guiding the shot through the mesh. The axis of the moving end of the reciprocating moving structure coincides with the inclination direction of the elliptical ring, pushing the shot and dust towards the upper part of the filter screen. Since the upper part of the filter screen is unoccupied, this improves the filtration efficiency of the shot, and the easy rolling of the shot makes it easier for it to move upwards and pass through the mesh. The reciprocating moving structure is located inside the upper part of the sliding groove. Because the filtration of the shot by the filter screen is mainly concentrated at the lower part, the reciprocating moving structure occupies a certain volume. The upper surface of the filter screen is wavy to increase the pushing effect on the shot and dust.

[0011] Furthermore, the sliding groove includes: an upper sliding surface parallel to the upper surface of the elliptical ring; a lower sliding surface parallel to the upper sliding surface; and several guide protrusions, each guide protrusion being elongated and triangular in cross-section, disposed on the upper and lower sliding surfaces, and arranged along the moving direction of the moving end of the reciprocating structure; the filter screen is provided with several guide grooves that cooperate with the guide protrusions. The cooperation between the guide grooves and guide protrusions allows the guide protrusions to slide within the guide grooves.

[0012] The guide protrusions and guide grooves are designed to guide the direction of the filter screen and reduce the pressure on the moving end of the reciprocating structure. The cross-section of the guide protrusion is triangular to improve the meshing effect between the guide groove and the guide protrusion.

[0013] Furthermore, it includes: a stirring shaft, which is disposed at the upper end of the first dust filter and below the shaking structure, with the lower end of the stirring shaft rotatably connected to the center of the first dust filter and perpendicular to the first dust filter; and several stirring plates, which are plate-shaped and disposed above the first dust filter and below the shaking structure, with one end of the stirring plate fixed to the stirring shaft and the lower end of the stirring plate adjacent to the first dust filter. The lower end of the stirring plate is provided with strip-shaped thin sheets, which are disposed on the side of the stirring plate along the rotation direction of the stirring plate and are inclined towards the first dust filter along the rotation direction of the stirring plate, and are in close contact with the upper surface of the first dust filter.

[0014] The rotating agitator shaft drives the agitator plate to rotate, pushing the pellets towards the top of the first dust filter screen. The rolling and airflow action cleans the dust off the surface of the pellets. The agitator shaft and agitator plate are used to clean the dust from the pellet surface. The pellets can clog the mesh of the first dust filter screen, reducing the airflow rate and thus the cleaning effect on the pellet surface. Because the mesh diameter of the first dust filter screen is smaller than the diameter of the pellets, only the lower hemisphere of the pellets falls into the mesh. Inclined strips are used to push the pellets out of the mesh.

[0015] Furthermore, the part clamping structure includes: a telescopic rod, which is disposed inside the housing and is vertically oriented. The upper end of the telescopic rod is rotatably connected to the center of the inner top of the housing, and the rotation axis of the telescopic rod coincides with the axis of the telescopic rod. The telescopic rod is connected to the controller. A clamping structure, disposed inside the housing, has its upper end fixedly connected to the lower end of the telescopic rod. The clamping structure includes: a mounting plate, disposed at the lower end of the telescopic rod and above the part, with the center of the top of the mounting plate fixed to the lower end of the telescopic rod; at least four finger assemblies, disposed below the mounting plate, with their upper ends rotatably connected to the edge of the mounting plate and engaging with the part; and at least four cylinders, corresponding to the finger assemblies, disposed on the side of the telescopic rod, with their upper ends rotatably connected to the telescopic rod and their lower ends rotatably connected to the middle of the finger assembly. The cylinders are connected to the controller. The finger assemblies engage with the part to fix it in place. A rubber layer is provided on the surface of the finger assemblies, and several anti-slip protrusions are provided on the side of the rubber layer facing the part.

[0016] When the shot peening position approaches the telescopic rod, the control finger assembly moves upward to avoid the shot. After the shot peening position has passed, the control finger assembly clamps the part. Shot peening can damage the finger assembly, so it needs to be protected. At least four finger assemblies are provided so that the part clamping structure can still hold the part even when one finger assembly disengages. A rubber layer is provided to deflect shot impacting the finger assembly, protecting it. Anti-slip protrusions are provided to enhance the clamping effect of the finger assembly on the part.

[0017] Furthermore, the protective structure includes: a protective cover, which is a box-like structure fixed to the inner wall of the housing; the protective cover covers the outside of the first gear, the second gear, the forward and reverse motor, and the shot peening head; the side of the protective cover facing the part is an arc-shaped surface, which is adapted to the rotation path of one end of the shot peening head; a protective opening, which is a through-hole located on the side of the protective cover facing the part; the protective opening is adapted to the rotation path of one end of the shot peening head and is fitted onto the shot peening head; an annular groove, which is located on the inner wall of the protective opening; and two limiting cavities, which are elongated cavities with a triangular cross-section; the limiting cavities are located inside the side of the protective cover facing the part, respectively located on both sides of the annular groove, and connected to one end of the shot peening head. The rotation path is adapted to the following: the triangular end of the limiting cavity facing the protective opening is connected to the annular groove; two winding cavities, which are hollow, are located inside the side of the protective cover facing the part, at both ends of the two limiting cavities, and are connected to both the limiting cavities and the annular groove; two elastic winding structures are respectively set in the two winding cavities; two chain beads are set in the limiting cavities, with both ends of the chain beads wound onto the two elastic winding structures, and the diameter of the chain beads is larger than the width of the annular groove; a circular sleeve is set inside the protective opening and fitted onto the shot peening head; a protective net is set inside the protective opening, with its two sides fixed to the two chain beads respectively, and its two ends wound onto the two elastic winding structures respectively, and its interior fixed to the edge of the circular sleeve.

[0018] The shot peening head rotates, causing the circular sleeve to move, which in turn moves the protective netting. The netting remains taut thanks to the elastic winding structure and chain beads, effectively blocking the shot. A limiting cavity is included to prevent the netting from falling off; the elastic winding structure keeps the netting taut.

[0019] A control method for a surface treatment system based on electromagnetic wave monitoring includes the following steps after the grinding system is started: A1: Several infrared radars perform an all-around scan of the part and transmit the data to a memory and an intelligent processor; A2: The controller controls the rotation of the telescopic rod and simultaneously controls the activation of several transverse shot peening nozzles; A3: After the part rotates 360 degrees, the controller controls the activation of several transverse shot peening nozzles; the intelligent processor retrieves data from the memory, compares the ground part with the unground part, calculates the ground thickness of the part surface, and defines a ground thickness less than X millimeters as a defective surface, obtaining a distribution map of defective surfaces; A4: The controller controls several shot peening heads to rotate so that their axes intersect at the top edge of the side of the part, and then controls the telescopic rod to retract at a uniform speed; A5: Using the movement path of the intersection point of the axes of several shot peening heads as the axis, ... The length is the distance the intersection point of the axes of several shot peening heads moves within T seconds, and the width is the distance the intersection point of the axes of several shot peening heads moves vertically within one rotation of the telescopic rod. The surface of the part is divided into finite identification units, and the identification unit that intersects with the distribution map of the defective surface of the part is set as a grinding unit. The intelligent processor calculates the fitting normal of the grinding unit and the angle between the fitting normal and the rotation axis of the part. A6: When the intersection point of the axes of several shot peening heads enters the grinding unit, according to the angle between the fitting normal of the grinding unit and the rotation axis of the part, the shot peening head whose axis is closest to the rotation axis of the part is selected to grind the grinding unit. When the defective surface in the grinding unit disappears, the shot peening head is controlled to close. A7: Repeat A6 until the intersection point of the axes of several shot peening heads leaves the surface of the part.

[0020] The intersection point of the axes of several shot peening heads remains stationary. Under the rotation and extension of the telescopic rod, this intersection point spirals downwards across the surface of the part. Using the movement path of this intersection point as the axis, the distance traveled by the intersection point within a time interval T seconds as the length, and the vertical distance traveled by the intersection point within one rotation of the telescopic rod as the width, the surface of the part is divided into finite identification units. The axis is the line connecting the midpoints of the two widths, allowing each identification unit to encompass the entire surface of the part. Changing T alters the length of the identification unit. Changing the rotation and extension speed of the telescopic rod alters the width of the identification unit. The rotational speed of the part is adapted to the shot peening speed of the transverse shot peening nozzle, ensuring that after one rotation and grinding, the surface of the part facing the transverse shot peening nozzle reaches the grinding standard.

[0021] Furthermore, including: A8: The intelligent processor retrieves pre-stored data about all effective surfaces of the part from the memory, compares it with the polished part, and if the number of effective surfaces decreases, it issues a warning message through the display.

[0022] The function of a part is largely determined by all its effective surfaces. If the number of effective surfaces decreases, the part's function will be missing or incomplete. During maintenance, the rotation speed of the part and the shot peening speed of the transverse shot peening nozzle are adjusted so that after one rotation and grinding, the surface of the part facing the transverse shot peening nozzle reaches the grinding standard.

[0023] Furthermore, including: B1: When the shot peening position approaches the finger assembly, control the cylinder to retract, causing the finger assembly to rotate above the mounting plate; B2: After the shot peening position passes the clamping position of the finger assembly, control the cylinder to extend, causing the finger assembly to rotate and clamp the part; B3: Repeat B1 and B2 in sequence until the grinding system stops.

[0024] By avoiding shot peening on the finger components, the service life of the part clamping structure can be extended.

[0025] The beneficial effects of this invention are: 1. The dust removal device can reduce the dust density inside the shell, improve the shot blasting quality, and clean the dust in the shot, making it easier for the recycling structure to be reused.

[0026] 2. It is equipped with several shot peening heads and a part clamping structure, which can perform precise grinding on the surface of the parts.

[0027] 3. By setting up at least four finger components and cylinders, the shot peening location can be avoided, extending the life of the part clamping structure. Attached Figure Description

[0029] The following will describe the concept and technical effects of the present invention clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of the present invention.

[0030] Example 1: like Figure 1 and Figure 4As shown, a surface treatment system based on electromagnetic wave monitoring includes: a housing 1; a part clamping structure disposed inside the housing 1, the upper end of the part clamping structure being rotatably connected to the inner top of the housing 1, and the lower end being connected to the part, the rotation axis of the part clamping structure being vertically oriented; a shot peening structure 9 disposed on the side of the housing 1; a plurality of transverse shot peening nozzles 2 disposed inside the housing 1, located on the inner sidewall of the housing 1, the plurality of transverse shot peening nozzles 2 being uniformly arranged vertically, the transverse shot peening nozzles 2 facing the rotation axis of the part clamping structure, the plurality of transverse shot peening nozzles 2 being connected to the shot peening structure 9; and a plurality of rotating shot peening nozzles 9. The shot peening device 3, a rotating shot peening device 3, is disposed on the inner wall of the housing 1, located to the side of the transverse shot peening port 2. Several rotating shot peening devices 3 are evenly arranged vertically, and each device 3 cooperates with a part. The rotating shot peening device 3 includes: a rotating shaft, which is transversely fixed to the inner wall of the housing 1 by a support frame; a first gear 33, the center of which is sleeved on the rotating shaft, and the first gear 33 is rotatably connected to the rotating shaft via a bearing; a forward and reverse rotating motor, disposed outside the first gear 33, with the rotation axis of the motor parallel to the axis of the first gear 33; and a second gear 32, disposed outside the first gear 33. The side center of gear 2 is fixed to the rotating shaft of the forward and reverse motor, and the second gear 32 meshes with the first gear 33; the shot peening head 34 is tubular and fixed to the side of the second gear 32, with one end facing the part and the other end connected to the shot peening mechanism through a pipe; a protective structure is provided on the outside of the first gear 33, the second gear 32, the forward and reverse motor and the shot peening head 34, and the protective structure cooperates with the rotation of the shot peening head 34; a recovery structure 4 is provided on the side of the housing 1, with one end connected to the shot peening structure 9 and the other end connected to the bottom of the inner side of the housing 1; a dust removal device is provided. The system includes: a housing 1 containing several infrared radars 5; an intelligent processor mounted on the housing 1 and connected to the infrared radars 5; a memory mounted on the housing 1 and connected to the infrared radars 5, and also connected to the intelligent processor; a controller mounted on the housing 1 and connected to the intelligent processor, several transverse shot peening nozzles 2, several rotating shot peening devices 3, and a parts clamping structure; and a display 6 mounted on the housing 1 and connected to the intelligent processor.

[0031] The parts are fixed in the center of the housing 1 by a part clamping structure. The rotation of the part clamping structure causes the parts to rotate, cooperating with several transverse shot peening nozzles 2 to polish the parts. Several infrared radars 5 are set on the inner wall of the housing 1 to scan the parts and record their surface conditions. After the transverse shot peening nozzles 2 polish the parts, the intelligent processor compares the initial surface data of the parts with the current surface data to obtain the polished thickness of each part surface. If the polished thickness does not meet the standard, several shot peening heads 34 are used to specifically polish the parts on the part surface that do not meet the polishing standard. If the effective surface of the part disappears after polishing, its function will also be damaged. At this time, an alarm is issued through the display 6, and the shot peening machine is inspected and repaired. The shot and dust fall to the bottom of the housing 1. The dust is cleaned by the dust removal device and then returned to the shot peening structure for recycling under the action of the recycling structure 4. Since the parts have already been polished by the transverse shot peening nozzles, the surfaces whose polished thickness does not meet the standard are non-transverse in the normal direction and need to be polished by the vertically inclined shot peening nozzles. Several vertical shot peening heads 34 are provided, intersecting at a single point, thus generating shot peening at different angles from the same point to improve the polishing quality of the part surface. Several infrared radars 5 are provided for monitoring the part surface. Several horizontal shot peening nozzles 2 and several shot peening heads 34 are provided for comprehensive and uniform cleaning of the part surface. A memory is provided to store the processing data of the intelligent processor, part surface data, and data of all effective surfaces of the part. A part clamping structure is provided to fix the part. A dust removal device is provided to remove dust from the shot and dust inside the housing 1.

[0032] The dust removal device includes: a blower 71, which is located at the top inside the housing 1; a suction fan 74, which is located at the bottom inside the housing 1, below the part; a first dust filter 73, which is located inside the housing 1, above the suction fan 74, below the part, below several transverse shot peening nozzles 2, and below several rotating shot peening devices 3. The mesh diameter of the first dust filter 73 is smaller than the diameter of the shot. The first dust filter 73 is inclined towards the connection between the housing 1 and the recovery structure 4, and the lower end of the first dust filter 73 matches the connection between the housing 1 and the recovery structure 4; and a shaking structure 72, which is located inside the housing 1. The part, whose side is connected to the inner wall of the housing 1, the shaking structure 72 is located above the first dust filter 73 and below the part, the shaking structure 72 is set below a plurality of transverse shot peening nozzles 2 and below a plurality of rotating shot peening devices 3, the shaking structure 72 is inclined in the opposite direction to the inclination direction of the first dust filter 73; the shaking structure 72 includes: a filter screen 722, the filter screen 722 is set inside the housing 1, above the first dust filter 73 and below the part, the filter screen 722 is set below a plurality of transverse shot peening nozzles 2 and below a plurality of rotating shot peening devices 3, the filter screen 722 is inclined in the opposite direction to the inclination direction of the first dust filter 73, and the mesh diameter of the filter screen 722 is adapted to the diameter of the shot.

[0033] The shot blasting material falls onto the filter screen 722, accumulates to one side under the action of the inclined surface, and passes through the mesh of the filter screen 722 under the action of the shaking structure 72, leaving behind larger dust particles. The shot blasting material then falls onto the first dust filter screen 73, rolls to one side under the action of the inclined surface, and during the rolling process, dust passes through the mesh of the first dust filter screen 73, and finally the shot blasting material is recovered by the recovery structure 4. The blower 71 blows outside air into the housing 1 from top to bottom, carrying away the dust in the shot blasting area. Then, most of the airflow passes through the mesh at the upper end of the filter screen 722 and enters the lower part, while a small portion passes through the shot blasting material accumulated at the lower end of the filter screen 722 and enters the lower part. Then, most of the airflow passes through the mesh at the upper end of the first dust filter screen 73 and enters the lower part, while a small portion passes through the shot blasting material accumulated at the lower end of the first dust filter screen 73 and enters the lower part. Finally, the airflow enters the suction fan 74 for purification and is discharged into the outside air. If both the first filter screen 722 and the second filter screen 722 are horizontally set, the pellets will be laid flat on their surface. The airflow carrying dust needs to pass through two layers of pellets before entering the suction fan 74, which will affect the dust removal effect and cause the clean pellets to absorb dust. Therefore, a mechanism is needed that allows the airflow carrying dust to directly enter the suction fan 74. The first dust filter screen 73 and the filter screen 722 are tilted to move the pellets to one side, exposing part of the first dust filter screen 73 and part of the filter screen 722. The first dust filter screen 73 is tilted towards the connection between the housing 1 and the recovery structure 4 to improve the recovery effect of the recovery structure 4. The filter screen 722 is tilted in the opposite direction to the tilt of the first dust filter screen 73, so that the pellets falling from the filter screen 722 need to roll for a period of time, which is beneficial for cleaning the dust on the surface of the pellets in coordination with the airflow. Since the shot falling onto the filter screen 722 also includes large particles such as rust and part dust, which can easily clog the mesh and reduce the speed at which the shot falls from the filter screen 722, leading to accumulation, shaking is necessary. The shaking structure 72 is designed to prevent shot from accumulating on the filter screen 722, clogging the shot blasting nozzle, and affecting the shot blasting process. It can also coordinate with the airflow to improve the dust removal effect. The shaking structure 72 also prevents the shot from covering the top of the filter screen 722, thus affecting airflow.

[0034] like Figure 2As shown, the shaking structure 72 includes: an elliptical ring disposed inside the housing 1, the elliptical ring being inclined in the opposite direction to the inclination direction of the first dust filter 73, its side being tightly connected to the inner wall of the housing 1, the elliptical ring being located above the first dust filter 73 and below the parts, the elliptical ring being disposed below several transverse shot peening nozzles 2 and below several rotating shot peening devices 3, a sliding groove being provided on the inner side of the elliptical ring, the sliding groove being annular, the sliding groove cooperating with the elliptical ring, a reciprocating moving structure 721 being provided inside the upper end of the sliding groove, the axis of the moving end of the reciprocating moving structure 721 coinciding with the inclination direction of the elliptical ring; a filter screen 722 disposed inside the elliptical ring, located inside the sliding groove, the filter screen 722 cooperating with the sliding groove, the filter screen 722 being movable within the sliding groove, the upper end of the filter screen 722 being connected to the reciprocating moving structure 721.

[0035] The reciprocating movement structure 721 pushes the filter screen 722 to move back and forth within the sliding groove, thus causing the filter screen 722 to vibrate. The sliding groove is provided to prevent dust from falling directly below without passing through the filter screen 722. The reciprocating movement structure 721 is used to move the filter screen 722 back and forth, allowing the shot to pass through the mesh. The axis of the moving end of the reciprocating movement structure 721 coincides with the inclination direction of the elliptical ring, driving the shot and dust towards the upper end of the filter screen 722. Since the upper end of the filter screen 722 is unoccupied, this increases the range of motion of the filter screen 722 in driving the shot and dust.

[0036] The system includes: a sliding groove comprising: an upper sliding surface, which is parallel to the upper surface of the elliptical ring; a lower sliding surface, which is parallel to the upper sliding surface; a plurality of guide protrusions, which are elongated and have a triangular cross-section, and are disposed on the upper and lower sliding surfaces, with the guide protrusions arranged along the moving direction of the moving end of the reciprocating moving structure 721; and a plurality of guide grooves on the filter screen 722, which cooperate with the guide protrusions.

[0037] The guide protrusion and guide groove are provided to guide the direction of the filter screen 722 and reduce the pressure on the moving end of the reciprocating moving structure 721. The cross-section of the guide protrusion is triangular to improve the meshing effect between the guide groove and the guide protrusion.

[0038] like Figure 3As shown, it includes: a stirring shaft 731, which is disposed on the upper end of the first dust filter 73 and below the shaking structure 72. The lower end of the stirring shaft 731 is rotatably connected to the center of the first dust filter 73 and is perpendicular to the first dust filter 73; and several stirring plates 732, which are plate-shaped and disposed on the upper end of the first dust filter 73 and below the shaking structure 72. One end of the stirring plate 732 is fixed to the stirring shaft 731, and the lower end of the stirring plate 732 is adjacent to the first dust filter 73. A strip-shaped sheet is disposed on the lower end of the stirring plate 732. The strip-shaped sheet 733 is disposed on the side of the stirring plate 732 along the rotation direction of the stirring plate 732 and is inclined towards the first dust filter 73 along the rotation direction of the stirring plate 732, and is in close contact with the upper surface of the first dust filter 73.

[0039] The rotating agitator shaft 731 drives the agitator plate 732 to rotate, pushing the pellets towards the upper end of the first dust filter screen 73, where the rolling and airflow cleans the dust from its surface. The agitator shaft 731 and agitator plate 732 are used to clean the dust from the pellets' surface. The pellets can clog the mesh of the first dust filter screen 73, reducing the airflow and its cleaning effect on the pellet surface. Because the mesh diameter of the first dust filter screen 73 is smaller than the diameter of the pellets, only the lower hemisphere of the pellets falls into the mesh. Inclined strips 733 are provided to push the pellets out of the mesh.

[0040] The part clamping structure includes: a telescopic rod 81, which is disposed inside the housing 1 and is vertically oriented. The upper end of the telescopic rod 81 is rotatably connected to the center of the top of the housing 1, and the rotation axis of the telescopic rod 81 coincides with the axis of the telescopic rod 81. The telescopic rod 81 is connected to a controller. A clamping structure is disposed inside the housing 1, and its upper end is fixedly connected to the lower end of the telescopic rod 81. The clamping structure includes: a mounting plate 82, which is disposed at the lower end of the telescopic rod 81 and positioned above the part. The top center of the mounting plate 82 is fixed to the lower end of the telescopic rod 81; at least four finger assemblies 84 are disposed below the mounting plate 82, the upper end of the finger assembly 84 is rotatably connected to the edge of the mounting plate 82, and the finger assembly 84 cooperates with the parts; at least four cylinders 83 are corresponding to the finger assemblies 84, the cylinders 83 are disposed on the side of the telescopic rod 81, the upper end of the cylinder 83 is rotatably connected to the telescopic rod 81, and the lower end is rotatably connected to the middle of the finger assembly 84, and the cylinder 83 is connected to the controller.

[0041] When the shot peening position approaches the telescopic rod 81, the control finger assembly 84 moves upward to avoid the shot peening. After the shot peening position has passed, the control finger assembly 84 clamps the part. Shot peening can damage the finger assembly 84, so it needs to be protected. At least four finger assemblies 84 are provided so that the part clamping structure can still clamp the part even when one finger assembly 84 is disengaged. The surface of the finger assembly 84 is provided with a rubber layer, and the rubber layer has several anti-slip protrusions on the side facing the part.

[0042] A rubber layer is provided to deflect impacting pellets onto the finger assembly 84, thus protecting the finger assembly 84. Anti-slip protrusions are provided to enhance the gripping effect of the finger assembly 84 on the parts.

[0043] like Figure 5 As shown, the protective structure includes: a protective cover 31, which is a box-like structure fixed to the inner wall of the housing 1. The protective cover 31 covers the outside of the first gear 33, the second gear 32, the forward and reverse motor, and the shot peening head 34. The side of the protective cover 31 facing the part is an arc-shaped surface, which is adapted to the rotation path of one end of the shot peening head 34; a protective opening 36, which is a through-hole located on the side of the protective cover 31 facing the part. The protective opening 36 is adapted to the rotation path of one end of the shot peening head 34 and is fitted onto the shot peening head 34; an annular groove located on the inner wall of the protective opening 36; and two limiting cavities, which are elongated cavities with a triangular cross-section. The limiting cavities are located inside the side of the protective cover 31 facing the part, located on both sides of the annular groove, and are connected to one end of the shot peening head 34. The rotation path is adapted to the following: the triangular end of the limiting cavity facing the protective opening 36 is connected to the annular groove; two winding cavities, which are hollow cavities, are located inside the side of the protective cover 31 facing the part, at both ends of the two limiting cavities, and are connected to the limiting cavities and the annular groove; two elastic winding structures 39 are respectively set in the two winding cavities; two chain beads 37 are set in the limiting cavities, with both ends of the chain beads 37 wound onto the two elastic winding structures 39, and the diameter of the chain beads 37 is larger than the width of the annular groove; a circular ring sleeve 35 is set inside the protective opening 36 and fitted onto the shot peening head 34; a protective net 38 is set inside the protective opening 36, with its two sides fixed to the two chain beads 37 respectively, and its two ends wound onto the two elastic winding structures 39 respectively, and its interior fixed to the edge of the circular ring sleeve 35.

[0044] The shot peening head 34 rotates, causing the ring sleeve 35 to move, which in turn moves the protective net 38. Under the action of the elastic winding structure 39 and the chain beads 37, the net remains taut, blocking the shot. A limiting cavity is provided to prevent the protective net 38 from falling off; the elastic winding structure 39 is provided to keep the protective net 38 taut.

[0045] The working process of this embodiment is as follows: The part is fixed in the center of the housing 1 by the part clamping structure. The rotation of the part clamping structure drives the part to rotate, and it cooperates with several transverse shot peening nozzles 2 to polish the part. Several infrared radars 5 are set on the inner wall of the housing 1 to scan the part and record the surface condition of the part. After the transverse shot peening nozzles 2 polish the part, the intelligent processor compares the initial surface data of the part with the current surface data to obtain the polished thickness of each part surface. If the polished thickness does not meet the standard, several shot peening heads 34 are used to perform targeted polishing on the part surface that does not meet the polishing standard. If the effective surface of the part disappears after polishing, its function will also be damaged. At this time, an alarm is issued through the display 6, and the shot peening machine is inspected and repaired. The shot and dust fall to the bottom of the housing 1. The dust is cleaned by the dust removal device and then returned to the shot peening structure for recycling under the action of the recycling structure 4. Since the parts have already been polished by the transverse shot blasting nozzle, the surfaces whose polished thickness does not meet the standard are those whose normal direction is not transverse. These surfaces require polishing with the vertically inclined shot blasting nozzle. Several vertically aligned shot blasting heads 34 are set up; since they intersect at a single point, they can generate shot blasting at different angles at the same point, improving the polishing quality of the parts' surfaces. The shot falls onto the filter screen 722, accumulates to one side under the action of the inclined surface, and passes through the mesh of the filter screen 722 under the action of the shaking structure 72, leaving behind larger dust particles. The reciprocating moving structure 721 pushes the filter screen 722 back and forth within the sliding groove, achieving the shaking of the filter screen 722. The shot then falls onto the first dust filter screen 73, rolls to one side under the action of the inclined surface, and during the rolling process, dust passes through the mesh of the first dust filter screen 73, ultimately allowing the shot to be recovered by the recovery structure 4. The blower 71 blows outside air into the housing 1 from top to bottom, carrying away the dust from the shot peening area. Most of the airflow then passes through the upper mesh of the filter screen 722 and enters the lower part, while a small portion passes through the shot accumulated at the lower end of the filter screen 722. Next, most of the airflow passes through the upper mesh of the first dust filter screen 73 and enters the lower part, while a small portion passes through the shot accumulated at the lower end of the first dust filter screen 73 and enters the lower part. Finally, the airflow enters the suction fan 74 for purification and is then discharged into the outside air. The stirring shaft 731 rotates, causing the stirring plate 732 to rotate, pushing the shot towards the upper end of the first dust filter screen 73, where the rolling and airflow clean the dust from its surface.

[0046] When the shot peening position approaches the telescopic rod 81, the control finger assembly 84 moves upward to avoid the shot peening. After the shot peening position has passed, the control finger assembly 84 clamps the part.

[0047] A control method for a surface treatment system based on electromagnetic wave monitoring includes the following steps after the grinding system is started: A1: Several infrared radars 5 perform an all-round scan of the part and transmit the data to a memory and an intelligent processor; A2: The controller controls the telescopic rod 81 to rotate and simultaneously controls several transverse shot peening nozzles 2 to start; A3: After the part rotates 360 degrees, the controller controls several transverse shot peening nozzles 2 to close; The intelligent processor retrieves data from the memory, compares the ground part with the unground part, calculates the ground thickness of the part surface, and defines a ground thickness less than X millimeters as a defective surface, obtaining a distribution map of defective surfaces of the part; A4: The controller controls several shot peening heads 34 to rotate so that their axes intersect at the top of the side of the part, and then controls the telescopic rod 81 to retract at a uniform speed; A5: Using the moving path of the intersection point of the axes of several shot peening heads 34 as the axis, within T seconds... The length is the distance the intersection point of the axes of several shot peening heads 34 moves, and the width is the distance the intersection point of the axes of several shot peening heads 34 moves in the vertical direction during one rotation of the telescopic rod 81. The surface of the part is divided into finite identification units, and the identification unit that intersects with the distribution map of the defective surface of the part is set as a grinding unit. The intelligent processor calculates the fitting normal of the grinding unit and the angle between the fitting normal and the rotation axis of the part. A6: When the intersection point of the axes of several shot peening heads 34 enters the grinding unit, according to the angle between the fitting normal of the grinding unit and the rotation axis of the part, the shot peening head 34 whose axis is closest to the rotation axis of the part is selected to grind the grinding unit. When the defective surface in the grinding unit disappears, the shot peening head 34 is controlled to close. A7: Repeat A6 until the intersection point of the axes of several shot peening heads 34 leaves the surface of the part.

[0048] The intersection point of the axes of several shot peening heads 34 remains stationary. Under the rotation and extension of the telescopic rod 81, this intersection point can spiral downwards across the surface of the part. Using the movement path of the intersection point as the axis, the distance traveled by the intersection point within T seconds as the length, and the vertical distance traveled by the intersection point within one rotation of the telescopic rod 81 as the width, the surface of the part is divided into finite recognition units. The axis is the line connecting the midpoints of the two widths, allowing each recognition unit to encompass the entire surface of the part. Changing T changes the length of the recognition unit. Changing the rotation and extension speed of the telescopic rod 81 changes the width of the recognition unit.

[0049] Includes: A8: The intelligent processor retrieves pre-stored data about all effective surfaces of the part from the memory, compares it with the polished part, and if the number of effective surfaces decreases, it issues a warning message through the display 6.

[0050] The function of a part is mostly determined by all its effective surfaces. If the number of effective surfaces is reduced, the part's function will be missing or incomplete.

[0051] Includes: B1: When the shot peening position approaches the finger assembly 84, the control cylinder 83 retracts, causing the finger assembly 84 to rotate above the mounting plate 82; B2: After the shot peening position passes the clamping position of the finger assembly 84, the control cylinder 83 extends, causing the finger assembly 84 to rotate and clamp the part; B3: Repeat B1 and B2 in sequence until the grinding system stops.

[0052] By keeping the finger assembly 84 away from shot peening, the service life of the part clamping structure can be extended.

[0053] The above embodiments are only some embodiments of the present invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.
