Description

Technical Field

[0001] This invention relates to the field of sandblasting equipment technology, and in particular to a support system and control method for sandblasting large cylindrical castings. Background Technology

[0002] Sandblasting is a process in which a high-speed jet of abrasive is propelled onto the surface of a workpiece, causing changes to its outer surface. Due to the impact and cutting action of the abrasive on the workpiece surface, the workpiece surface achieves a certain degree of cleanliness and different roughness, thereby improving the mechanical properties of the workpiece surface.

[0003] In some fields, it is necessary to sandblast all surfaces of large, thin-walled, cylindrical or near-cylindrical aluminum alloy castings, including the inner cavity and outer wall surfaces.

[0004] When performing sandblasting on large castings with a diameter exceeding 350mm and a height exceeding 500mm, many specific difficulties are usually encountered. To achieve overall sandblasting of large castings, the sandblasting chamber needs to be opened repeatedly during the sandblasting process, and multiple people / times need to manually rotate and adjust the angle of the casting to ensure that all surfaces of the casting meet the process requirements.

[0005] During this process, operators are exposed to harsh working conditions and expend enormous physical energy. Not only is work efficiency low and labor intensity high, but the operation is also highly arbitrary, with unreasonable flipping angles preventing uniform sandblasting of the castings and easily creating blind spots. For large castings, multiple operators are required simultaneously to achieve the desired flipping and angle adjustment.

[0006] To ensure the mechanical properties of castings, especially the quality of structural components for aerospace applications, which can meet the needs of drastically changing environments, it is crucial to improve the quality of sandblasting. One of the technical measures is to improve the sandblasting process to fully enhance the mechanical properties of castings during the sandblasting process. Summary of the Invention

[0052] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments thereof, serve to illustrate the principles of the present invention; and are not intended to limit the scope of the present invention.

[0053] The following is combined Figures 1-11 The technical solution of the present invention will be described in detail with specific embodiments.

[0054] First, define the guide rail direction of track unit 11 as longitudinal, and the direction perpendicular to the guide rail as transverse.

[0055] Example 1

[0056] A support system for sandblasting large cylindrical castings.

[0057] like Figure 1-10 As shown in Example 1, a support system for sandblasting large cylindrical castings is provided for the all-round, automatic control of sandblasting operations on large cylindrical castings 200 within a sandblasting room.

[0058] Figure 1 As shown, the support system for sandblasting large cylindrical castings in this embodiment 1 includes a control terminal 100, an overall moving component 1, a position adjusting component 2, and a limiting component 3.

[0059] The integral moving component 1 and the position adjusting component 2 together form a support device for sandblasting large cylindrical castings.

[0060] The control terminal 100 controls the displacement and / or rotation of the overall moving component 1 and the position adjusting component 2 based on the signal fed back by the limiting component 3.

[0061] Specifically, the control terminal 100 includes a position determination unit and a displacement control unit. The control terminal 100 receives the position signal fed back by the limit component 3, determines it through the position determination unit, and executes automated control of the sandblasting process, including the horizontal rotation and linear displacement of the large cylindrical casting 200 in the sandblasting chamber, through the displacement control unit, so as to efficiently complete the all-round sandblasting operation of the casting.

[0062] First, we introduce the technical solution for the support device for sandblasting large cylindrical castings, which constitutes the support system for sandblasting large cylindrical castings.

[0063] like Figure 10 and Figure 2As shown, the support device for sandblasting large cylindrical castings includes an integral moving component 1 and a position adjusting component 2. The casting 200 is rotatably supported on the position adjusting component 2. The integral moving component 1 can drive the casting 200 to move longitudinally and can rotate in the horizontal plane. The position adjusting component 2 is rotatably connected to the upper part of the integral moving component 1 and can drive the casting 200 to make fine adjustments in both the horizontal and longitudinal directions. It can also drive the casting 200 to rotate along its own axis.

[0064] like Figure 3 As shown, the overall moving component 1 includes a track unit 11, a support vehicle assembly 12, an overall rotating assembly 13, and a support vehicle power unit 14. The track unit 11 includes two parallel guide rails; the support vehicle assembly 12 can roll and move on the track unit 11 under the drive of the support vehicle power unit 14; the overall rotating assembly 13 is rotatably connected to the support vehicle assembly 12.

[0065] Specifically, the support vehicle assembly 12 includes a support vehicle body unit 121 and wheels 122 disposed at the lower part of the support vehicle body unit 121.

[0066] like Figure 6 As shown, wheel 122 includes two pairs of wheels. The pair of wheels in front are driven wheels, and the pair of wheels in the rear are driving wheels. The two driving wheels are driven by the support vehicle power unit 14, so that the entire support vehicle assembly 12 and its components can be longitudinally displaced along the guide rail.

[0067] like Figure 3 and Figure 6 As shown, the support vehicle power unit 14 includes a support vehicle power source 141, a support vehicle power source mounting plate 142, and a support vehicle coupling 143. The support vehicle power source 141 is suspended on the support vehicle assembly 12 via the support vehicle power source mounting plate 142.

[0068] Preferably, the power source 141 of the support vehicle is a bidirectional output stepper motor, and the two ends of the bidirectional output stepper motor are respectively connected to the rotating shafts of the two driving wheels through the support vehicle coupling 143.

[0069] The supporting vehicle body unit 121 includes a supporting vehicle body 1211 with a truss structure and a supporting vehicle column 1212 located at the upper center of the supporting vehicle body 1211.

[0070] The support vehicle body 1211 adopts a truss structure, which can effectively reduce the weight of the support device while ensuring strength, so as to save power.

[0071] The support column 1212 is a sleeve structure that penetrates the support vehicle body 1211 and serves as a support sleeve for the functional unit that allows the position adjustment component 2 to rotate relative to the overall moving component 1. The overall rotating assembly 13 transmits rotational power to the position adjustment component 2 through the support column 1212.

[0072] like Figure 3 and Figure 5 As shown, the overall rotating assembly 13 includes an overall rotating driven unit 131 and an overall rotating driving unit 132. The rotating driven unit 131 includes a driven gear 1311, and the overall rotating driving unit 132 includes a driving gear 1324; the driven gear 1311 and the driving gear 1324 form a gear pair.

[0073] Specifically, the overall rotation active unit 132 also includes an overall rotation power source 1321, an overall rotation coupling 1323, and an active rotation shaft 1325.

[0074] Preferably, the overall rotary power source 1321 is vertically fixed at the upper edge of the support vehicle body 1211, with the output shaft pointing downwards. The distance between the center of the output shaft of the overall rotary power source 1321 and the axis of the support vehicle column 1212 is equal to the center distance of the gear pair of the overall rotary active unit 132.

[0075] Preferably, the integral rotary power source 1321 is an integral rotary stepper motor. The output shaft of the integral rotary stepper motor is connected to the drive rotary shaft 1325 through an integral rotary coupling 1323. The drive rotary shaft 1325 is connected to the drive gear 1324 located at the lower part of the support vehicle body 1211 by a key, thereby transmitting the rotational power of the integral rotary power source 1321 to the drive gear 1324.

[0076] Specifically, the rotary driven unit 131 also includes a driven rotary shaft 1312. The lower end of the driven rotary shaft 1312 is fixedly connected to the driven gear 1311 via a key, and the upper end of the driven rotary shaft 1312 is fixedly connected to the position adjustment component 2. Preferably, the driven rotary shaft 1312 is provided with an external thread, which is screwed to the position adjustment component 2. The driven gear 1311 meshes with the driving gear 1324, transmitting the rotational power of the overall rotary stepper motor of the rotary power source 1321 to the position adjustment component 2, so that the position adjustment component 2 rotates 360° horizontally relative to the overall structure of the overall moving component 1.

[0077] In addition, the gear pairs need to be protected in the harsh working environment of the sandblasting room.

[0078] Preferably, the overall rotating assembly 13 of this embodiment 1 also includes a gear protection unit 133, which is used to support and hoist the driven gear 1311 and the driving gear 1324 on the one hand, and to protect the gear pair on the other hand, so that the driven gear 1311 and the driving gear 1324 are always in a normal engagement state throughout the entire working process.

[0079] Specifically, the gear protection unit 133 includes a gear protection upper cover 1331 and a gear protection lower cover 1332, with the gear protection upper cover 1331 connected to the gear protection lower cover 1332 at the edge.

[0080] Preferably, the gear protective cover 1332 is fixedly connected to the lower end face of the truss structure of the supporting vehicle body 1211. By pressing the outer ring of the bearing, the gear protective cover 1332 movably connects and presses the integral rotating driven unit 131 and the integral rotating active unit 132 of the bearing inner ring.

[0081] By controlling the speed and direction of the overall rotary stepper motor of the overall rotary power source 1321, the angle of the casting 200 on the support device can be easily changed so as to cooperate with the sandblasting machine to perform a 360° horizontal sandblasting operation on the casting 200.

[0082] Combination Figure 10 , Figure 2 and Figure 4 As shown, the position adjustment component 2 includes a longitudinal adjustment assembly 21 and multiple transverse adjustment assemblies 22. The multiple transverse adjustment assemblies 22 are arranged parallel to and perpendicular to the longitudinal adjustment assembly 21. The casting 200 is supported on the multiple transverse adjustment assemblies 22.

[0083] In this preferred embodiment 1, there are two lateral adjustment components 22, and the lateral adjustment components 22 also have the function of rotating the casting 200 supported on them along their own axis.

[0084] Combination Figure 3 and Figure 7 The longitudinal adjustment assembly 21 includes a longitudinal adjustment power source 211, a longitudinal adjustment coupling 212, a longitudinal adjustment support frame 213, a longitudinal adjustment lead screw 214, a longitudinal adjustment bearing 215, and a longitudinal adjustment power source mounting frame 217.

[0085] like Figure 7 and Figure 9 As shown, the longitudinal adjustment support frame 213 is a box-groove structure with a column at the bottom. The longitudinal adjustment support frame 213 specifically includes a longitudinal adjustment support frame body 2131 and a longitudinal adjustment support frame rotating column 2132.

[0086] Specifically, the longitudinal adjustment support frame 2131 has a box-groove structure. A longitudinal adjustment reinforcing rib is provided in the middle of the longitudinal adjustment support frame 2131. A longitudinal adjustment support frame center hole 21311 is provided on the longitudinal adjustment reinforcing rib for installing the longitudinal adjustment bearing 215. A longitudinal adjustment support frame side hole 21312 is provided on the side surfaces at both ends of the longitudinal adjustment support frame 2131 for installing the longitudinal adjustment coupling 212.

[0087] Preferably, the longitudinal adjustment support frame 2131 has sand-receiving grooves on both sides of the bottom surface of the groove to temporarily accommodate sandblasting particles entering the longitudinal adjustment support frame 2131; sand removal holes 21313 are provided at the bottom of one or both ends of the longitudinal adjustment support frame 2131, and the sand removal holes 21313 are connected to the sand-receiving grooves to facilitate the removal of sand particles. This is beneficial for the longitudinal adjustment component 21 to work normally in the sandblasting environment and also facilitates the maintenance of the subsequent support device.

[0088] Preferably, in this embodiment 1, the longitudinal adjustment component 21 is provided with two longitudinal adjustment screws 214, which are respectively disposed in the longitudinal adjustment support frame 2131 box and located on both sides of the longitudinal adjustment reinforcing rib provided in the middle of the longitudinal adjustment support frame 2131, so as to drive one transverse adjustment component 22 to make synchronous or asynchronous longitudinal position adjustment, so as to adapt to the support of castings 200 of different lengths or with tapers.

[0089] Preferably, the center hole 21311 of the longitudinal adjustment support frame is a symmetrical stepped hole, and a longitudinal adjustment bearing 215 is installed on each side for limiting. The first end of the longitudinal adjustment screw 214 is connected to the longitudinal adjustment bearing 215.

[0090] Both ends of the longitudinal adjustment support frame 2131 are connected to a longitudinal adjustment power source 211 via a longitudinal adjustment power source mounting bracket 217. Preferably, the longitudinal adjustment power source 211 is a longitudinal adjustment stepper motor. The output shaft of the longitudinal adjustment stepper motor is connected to the longitudinal adjustment coupling 212 in the side hole 21312 of the longitudinal adjustment support frame via a limiting connection. The second end of the longitudinal adjustment screw 214 is connected to the longitudinal adjustment coupling 212. The longitudinal adjustment screw 214 and the nut on the transverse adjustment assembly 22 form a helical pair.

[0091] Preferably, to reduce the impact of sandblasting on the operation of the longitudinal adjustment screw 214, a longitudinal adjustment protective cover 216 is provided at the upper end of the longitudinal adjustment support frame 2131. More preferably, to avoid interfering with the longitudinal displacement adjustment of the transverse adjustment component 22, the longitudinal adjustment protective cover 216 needs to be designed as two overlapping sheet materials in a longitudinal structure, so that the transverse adjustment component 22 can pass through the gap between the two sheet materials, and after the transverse adjustment component 22 passes through, the two sheet materials can re-overlap and close, continuing to protect the internal structure of the longitudinal adjustment support frame 2131 from the impact of sandblasting.

[0092] Preferably, the longitudinal adjustment protective cover 216 includes two flexible magnetic strip seals; specifically, the flexible magnetic strip seal material is soft rubber.

[0093] The two flexible magnetic strips are each inlaid with a soft magnetic seal on their adjacent inner sides. The two soft magnetic seals overlap to form a longitudinal adjustment protective cover magnetic suction port 2161. This allows the lateral adjustment component 22 to push the two flexible magnetic strips open and pass through. After the lateral adjustment component 22 slides past, the longitudinal adjustment protective cover magnetic suction port 2161 of the two flexible magnetic strips can be magnetically closed.

[0094] Preferably, in this embodiment 1, the two flexible magnetic strips are fixed to the outer edges of the sealing area by pressure plates on the two sides of the upper end face of the longitudinal adjustment support frame 2131 box groove, so that the longitudinal adjustment protective cover 216 is stable and will not shift, and can always protect the interior of the longitudinal adjustment support frame 2131 box groove from a large amount of sand entering during the sandblasting operation.

[0095] like Figure 3 and Figure 5 As shown, the longitudinal adjustment support frame rotating column 2132 serves as the rotation center of the position adjustment component 2 and is located at the center of the lower end face of the longitudinal adjustment support frame body 2131 box groove, so as to ensure the positional stability of the position adjustment component 2 and the casting 200 supported by it throughout the sandblasting process.

[0096] The lower end face of the main body of the longitudinal adjustment support frame rotating column 2132 is provided with a longitudinal adjustment support frame rotating connection hole 21321. The longitudinal adjustment support frame rotating connection hole 21321 is a threaded hole, which is used to screw the external thread at the upper end of the driven rotating shaft 1312.

[0097] Combination Figure 2 and Figure 8As shown, the lateral adjustment component 22 includes a lateral active adjustment unit 221, a lateral driven adjustment unit 222, and a lateral adjustment walking unit 223. The lateral adjustment walking unit 223 is movably connected to the longitudinal adjustment component 21 via a central vertical connection and can perform longitudinal displacement adjustment on the longitudinal adjustment component 21. The lateral active adjustment unit 221 and the lateral driven adjustment unit 222 are movably disposed on both sides of the lateral adjustment walking unit 223 and can respectively perform lateral displacement adjustment along the lateral adjustment walking unit 223.

[0098] like Figure 8 As shown, the lateral adjustment and travel unit 223 includes a lateral adjustment and travel power source 2231, a lateral adjustment and travel coupling 2232, a lateral adjustment and travel support frame 2233, a lateral adjustment and travel lead screw 2234, a lateral adjustment and travel bearing 2235, and a lateral adjustment and travel power source mounting housing 2237.

[0099] Combination Figure 4 , Figure 8 and Figure 9 As shown, the lateral adjustment and walking support frame 2233 has a box-groove structure and a nut structure at the bottom; the lateral adjustment and walking support frame 2233 specifically includes the lateral adjustment and walking support frame body 22331 and the lateral adjustment and walking support frame nut 22332.

[0100] Specifically, the lateral adjustment and travel support frame 22331 is a box-groove structure with a lateral adjustment reinforcing rib in the middle. A lateral adjustment and travel support center hole 223311 is provided on the lateral adjustment reinforcing rib in the middle for installing the lateral adjustment and travel bearing 2235. Lateral adjustment and travel support side holes 223312 are provided on the side surfaces at both ends of the lateral adjustment and travel support frame 22331 for installing the lateral adjustment and travel coupling 2232.

[0101] Preferably, sand removal holes can also be provided at the bottom of one or both ends of the lateral positioning and walking support frame 22331. These holes, along with sand-receiving grooves on both sides of the bottom surface of the lateral positioning and walking support frame 22331, are used to temporarily accommodate sandblasting material entering the lateral positioning and walking support frame 22331 and facilitate subsequent sandblasting removal. This is beneficial for the lateral positioning and walking unit 223 to operate normally in a sandblasting environment and also facilitates the maintenance of the subsequent support device.

[0102] In this preferred embodiment 1, the lateral adjustment and walking unit 223 is provided with two lateral adjustment and walking screws 2234, which are respectively disposed in the box of the lateral adjustment and walking support frame 22331 and located on both sides of the lateral adjustment reinforcing rib in the middle of the lateral adjustment and walking support frame 22331, so as to drive the lateral active adjustment unit 221 and the lateral driven adjustment unit 222 located on both sides of the lateral adjustment and walking unit 223 to make synchronous or asynchronous lateral position adjustments, so as to adapt to the support of the casting 200 of cylinders with different cross-sectional radii or non-cylindrical barrels with the same cross-section.

[0103] Preferably, the center hole 223311 of the lateral adjustment travel support is a symmetrical stepped hole, and a lateral adjustment travel bearing 2235 is installed on each side for limiting. The lateral adjustment travel bearing 2235 is connected to the lateral adjustment travel coupling 2232.

[0104] The outer sides of both ends of the lateral adjustment and walking support frame 22331 are respectively connected to a lateral adjustment and walking power source 2231 through the lateral adjustment and walking power source mounting shell 2237. Preferably, the lateral adjustment and walking power source 2231 is a lateral adjustment and walking stepper motor. The output shaft of the lateral adjustment and walking stepper motor is connected to the lateral adjustment and walking coupling 2232 in the lateral adjustment and walking support side hole 223312 through a limiting connection.

[0105] The first end of the lateral adjustment travel screw 2234 is connected to the lateral adjustment travel bearing 2235, and the second end of the lateral adjustment travel screw 2234 is connected to the lateral adjustment travel coupling 2232. The two lateral adjustment travel screws 2234 form an active screw pair and a driven screw pair with the nuts on the lateral active adjustment unit 221 and the lateral driven adjustment unit 222, respectively, thereby driving the lateral active adjustment unit 221 and the lateral driven adjustment unit 222 to make lateral displacement on the lateral adjustment travel unit 223.

[0106] Similar to the longitudinal adjustment protective cover 216 on the longitudinal adjustment support frame 2131, preferably, in order to reduce the impact of sandblasting on the operation of the transverse adjustment walking support frame 2233, a transverse adjustment walking protective cover 2236 is provided at the upper end of the transverse adjustment walking support frame 2233; the transverse adjustment walking protective cover 2236 is provided with a transverse adjustment walking protective cover magnetic suction port 22361.

[0107] In a further preferred embodiment, the two edges of the soft rubber of the flexible magnetic strip seal in this embodiment are fixed to the upper end face 2 of the lateral adjustment and walking support frame 22331 box groove by pressure plates, so that the lateral adjustment and walking protective cover 2236 will not shift.

[0108] The lateral adjustment walking support frame nut 22332 is located at the center of the lower end face of the lateral adjustment walking support frame body 22331 box groove. The lateral adjustment walking support frame nut 22332 and the longitudinal adjustment screw 214 on the longitudinal adjustment component 21 form a helical pair. Under the drive of the longitudinal adjustment power source 211, the lateral adjustment component 22 can drive the casting 200 supported by it to make longitudinal position adjustment on the longitudinal adjustment support frame 213.

[0109] Specifically, the lateral adjustment travel support frame screw hole 223321 on the lateral adjustment travel support frame nut 22332 engages with the thread on the longitudinal adjustment screw 214; the longitudinal adjustment screw 214 rotates, causing the lateral adjustment travel support frame nut 22332 to make linear displacement.

[0110] Both the lateral active adjustment unit 221 and the lateral driven adjustment unit 222 have adjustment wheels, adjustment wheel mounting brackets and adjustment moving arms. The lateral active adjustment unit 221 is also equipped with an active rotation power mechanism.

[0111] This embodiment 1 only describes the structure of the lateral active adjustment unit 221.

[0112] First, the part of the lateral active adjustment unit 221 that has the same structure as the lateral passive adjustment unit 222 will be introduced.

[0113] like Figure 8 As shown, the lateral active positioning unit 221 includes a lateral positioning wheel 2211, a lateral positioning wheel mounting frame 2212, a lateral positioning moving arm unit 2213, and a lateral active rotation power unit.

[0114] The lateral adjustment moving arm unit 2213 includes a lateral active adjustment moving arm 22131 and a lateral active adjustment nut 22132. The lateral active adjustment moving arm 22131 is a bent column. The upper end of the lateral active adjustment moving arm 22131 is connected to the lateral adjustment wheel mounting bracket 2212, and the lower end of the lateral active adjustment moving arm 22131 is connected to the cubic lateral active adjustment nut 22132. A pair of side faces of the lateral active adjustment nut 22132 are provided with through threaded holes. The lateral active adjustment nut 22132 with threaded holes forms an active screw pair with the lateral adjustment travel screw 2234 on the other side. The lateral driven adjustment nut with threaded holes forms a driven screw pair with another lateral adjustment travel screw 2234.

[0115] The transverse adjusting wheel 2211 includes an adjusting wheel body and a first central rotating shaft and a second central rotating shaft located at the center of both sides of the adjusting wheel body. The transverse adjusting wheel mounting bracket 2212 is a frame structure with two vertical lugs. The two vertical lugs are provided with adjusting wheel mounting holes for connecting the transverse adjusting wheel 2211. The lower end of the transverse adjusting moving arm unit 2213 is movably connected to the longitudinal adjusting screw 214 on one side by a nut, and the upper end of the transverse adjusting moving arm unit 2213 is connected to the center of the bottom outer side of the frame plate of the transverse adjusting wheel mounting bracket 2212.

[0116] The structure of this part of the lateral active adjustment unit 221 is the same as that of the lateral passive adjustment unit 222.

[0117] The difference between the lateral passive adjustment unit 222 and the lateral active adjustment unit 221 is that:

[0118] The first and second central rotation axes of the lateral driven adjustment unit 222 are optical axes. The lateral driven adjustment wheel can be directly installed at the adjustment wheel mounting holes of the vertical lugs of the lateral adjustment wheel mounting bracket 22122, or indirectly installed on the lateral adjustment wheel mounting bracket 2212 through the bearings set at the adjustment wheel mounting holes, so as to rotate automatically after being subjected to force. The first central rotation axis of the lateral adjustment wheel 22112 central rotation axes of the lateral active rotation power unit is connected to the lateral active rotation power unit through the lateral adjustment wheel mounting bracket 2212. Under the drive and braking of the lateral active rotation power unit, the lateral adjustment wheel 2211 rotates controllably.

[0119] like Figure 8 As shown, the lateral active rotation power unit includes a lateral adjustment rotation power source 2214, a lateral adjustment rotation coupling 2215, and a lateral adjustment rotation power source mounting housing 2216. The lateral adjustment rotation power source 2214 is mounted on the lateral adjustment rotation power source mounting housing 2216, and one side end of the lateral adjustment rotation power source mounting housing 2216 is fixedly connected to the lateral adjustment wheel mounting bracket 2212.

[0120] Preferably, the lateral adjustment rotation power source 2214 is a lateral active adjustment stepper motor. The output shaft of the lateral active adjustment stepper motor is connected to the first central rotation shaft of the lateral adjustment wheel 2211 through the lateral adjustment rotation coupling 2215. The start and stop of the active adjustment stepper motor drive the lateral adjustment wheel 2211 to rotate or stop.

[0121] The lateral adjustment rotation power source 2214 of the two sets of lateral active adjustment units 221 rotates in the same direction at the same time, which enables the casting 200 supported on the position adjustment component 2 to rotate or brake along its own axis.

[0122] like Figure 1As shown, the support system for sandblasting large cylindrical castings in this embodiment 1 also includes a limiting component 3 and a control terminal 100. The control terminal 100 includes a position determination unit. The control terminal 100 receives the position signal fed back by the limiting component 3 and uses the position determination unit to automatically control the sandblasting process, including the horizontal rotation and linear displacement of the large cylindrical casting 200 in the sandblasting chamber, so as to efficiently complete the all-round sandblasting operation of the casting.

[0123] like Figure 1 , Figure 10 and Figure 6 As shown, the limiting component 3 includes an overall moving position switch assembly 31, a longitudinal adjustment switch assembly 32, and a lateral adjustment switch assembly 33.

[0124] like Figure 3 and Figure 6 As shown, the overall movement position switch assembly 31 includes an overall movement longitudinal entry switch 311, an overall movement longitudinal exit switch 312, and an overall movement rotary switch 313.

[0125] When the longitudinal entry switch 311 senses that the support vehicle assembly 12 has entered the sandblasting work area under the drive of the support vehicle power source 141, specifically when the mounting plate of the wheel 122 approaches the longitudinal entry switch 311, the control terminal will start the sandblasting gun to begin sandblasting the casting 200 of the position adjustment component 2. Based on the set rotation rate, the stepper motor of the lateral adjustment rotation power source 2214 will be activated to cause the casting 200 to begin rotating, and the stepper motor of the overall rotation power source 1321 will be activated to cause the position adjustment component 2 to rotate horizontally around the support vehicle column 1212. The rotation rate of the support vehicle power source 141 will be adjusted to enter the sandblasting travel mode, and it will stop moving at a very low speed to ensure that both the outer and inner walls of the casting 200 are sandblasted. The parameters of the support vehicle power source 141, the lateral adjustment rotation power source 2214, and the overall rotation power source 1321 can all be set in the control software of the control terminal 100 according to the sandblasting gun parameters, the shape and size of the casting 200.

[0126] When the longitudinal departure switch 312 senses the entry of the support vehicle assembly 12, it indicates that the support device has carried the casting 200 and is about to leave the sandblasting work area. The control terminal 100 can determine whether the support device has mistakenly moved straight in or the sandblasting process of the casting has ended based on the operation time. If it is a misoperation, the control terminal 100 can control the support vehicle power source 141 to drive the support device back to the starting position and re-enter. If it is a normal operation and the sandblasting has ended, the control terminal 100 will control the sandblasting gun to stop operation, and the control terminal 100 can control the support vehicle power source 141 to drive the support device to carry the casting 200 out of the sandblasting room.

[0127] The overall movable rotary switch 313 is connected to the upper edge of the support column 1212 via a support plate to sense whether the rotation angle of the longitudinal adjustment component 21 has reached 180° or 360°.

[0128] Preferably, the distance between the center of the overall movable rotary switch 313 and the center of the support column 1212 is greater than half the maximum solid width of the longitudinal adjustment component 21, so as to facilitate... Figure 10 In the position shown, when the longitudinal adjustment component 21 rotates 180° around the support column 1212, continues to rotate to 360° and returns to the original position, or rotates 180° in the opposite direction and returns to the original position, the overall movement rotary switch 313 will send a position signal to the control terminal so that the overall rotation power source 1321 can perform the next predetermined action.

[0129] like Figure 10 and Figure 7 As shown, the longitudinal adjustment switch assembly 32 is disposed on the side wall of the longitudinal adjustment support frame 2131. The longitudinal adjustment switch assembly 32 is used to limit the two extreme positions of the lateral adjustment assembly 22 on the longitudinal adjustment support frame 2131.

[0130] The longitudinal adjustment switch assembly 32 includes two sets of longitudinal adjustment switch units. The longitudinal adjustment switch units include a longitudinal adjustment inner switch 321 and a longitudinal adjustment outer switch 322. The longitudinal adjustment inner switch 321 and the longitudinal adjustment outer switch 322 of the two sets of longitudinal adjustment switch units are mirror images of the longitudinal adjustment reinforcing rib in the middle of the longitudinal adjustment support frame 2131.

[0131] When the two lateral adjustment components 22 move inward relative to each other to accommodate the shorter casting 200, the lateral adjustment components 22 move to a position that the longitudinal adjustment inner switch 321 can sense. The control terminal 100 will stop the longitudinal adjustment power source 211 from rotating to prevent the two lateral adjustment components 22 from colliding and being damaged.

[0132] When the two lateral adjustment components 22 move outwards and away from each other to accommodate the longer casting 200, the lateral adjustment components 22 move to a position that the longitudinal adjustment external switch 322 can sense. The control terminal 100 will stop the longitudinal adjustment power source 211 from rotating to prevent the lateral adjustment walking support frame nut 22332 of the lateral adjustment component 22 from coming off the longitudinal adjustment screw 214, causing equipment damage or maintenance difficulties.

[0133] If the longitudinal adjustment component 22 does not trigger the longitudinal adjustment inner switch 321 and the longitudinal adjustment outer switch 322 during the process of adjusting the longitudinal position relative to the longitudinal adjustment support frame 2131, it indicates that the process of adjusting the longitudinal position of the transverse adjustment component 22 is normal and can continue until the distance between the two transverse adjustment components 22 is suitable for the length of the casting 200.

[0134] Preferably, the two flexible magnetic strips of the longitudinal adjustment protective cover 216 are bent from the upper end of the longitudinal adjustment support frame 2131's groove towards the side of the groove. The longitudinal adjustment inner switch 321 and the longitudinal adjustment outer switch 322 are respectively installed on the two sides of the longitudinal adjustment support frame 2131's groove. The longitudinal adjustment inner switch 321 and the longitudinal adjustment outer switch 322 clamp the longitudinal adjustment protective cover 216 from both sides and then fix it to the side wall of the longitudinal adjustment support frame 2131. While functioning as a proximity switch, the longitudinal adjustment switch assembly 32 also fixes the longitudinal adjustment protective cover 216 to the side wall of the longitudinal adjustment support frame 2131, further preventing the longitudinal adjustment protective cover 216 from falling off.

[0135] like Figure 10 and Figure 8 As shown, the lateral adjustment switch assembly 33 includes two sets of lateral adjustment switch units, each including an inner lateral adjustment switch 331 and an outer lateral adjustment switch 332. The lateral adjustment switch assembly 33 is used to define two extreme positions of the lateral active adjustment unit 221 and the lateral driven adjustment unit 222 on the lateral adjustment travel unit 223.

[0136] The two sets of lateral adjustment switch units are mirror images of the lateral adjustment reinforcing ribs in the middle of the lateral adjustment walking support frame 22331.

[0137] When a pair of lateral active adjustment units 221 and lateral passive adjustment units 222 move inward relative to each other to accommodate the casting 200 with a smaller radial dimension, the lateral adjustment inner switch 331 can sense the position of the lateral active adjustment units 221 and lateral passive adjustment units 222. The control terminal 100 will stop the rotation of the lateral adjustment walking power source 2231 to prevent the lateral active adjustment units 221 and lateral passive adjustment units 222 from moving beyond their limits, disengaging from the lateral adjustment walking screw 2234, or even colliding with the lateral adjustment reinforcing rib of the lateral adjustment walking support frame 22331, so as to prevent damage to the lateral adjustment assembly 22.

[0138] When a pair of lateral active adjustment units 221 and lateral passive adjustment units 222 move outwards and opposite to each other to accommodate a casting 200 with a larger radial dimension, the lateral active adjustment unit 221 and / or the lateral passive adjustment unit 222 move to a position that the lateral adjustment external switch 332 can sense, stopping the rotation of the lateral adjustment travel power source 2231 to prevent the lateral active adjustment unit 221 and the lateral passive adjustment unit 222 from exceeding their limits and disengaging from the lateral adjustment travel screw 2234, and to prevent the lateral adjustment travel support frame nut 22332 of the lateral active adjustment unit 221 and / or the lateral passive adjustment unit 222 from disengaging from the longitudinal adjustment screw 214, causing equipment damage or maintenance difficulties.

[0139] When a pair of lateral active adjustment units 221 and lateral driven adjustment units 222 are adjusting their lateral positions on the lateral adjustment walking unit 223, if the lateral adjustment inner switch 331 and the lateral adjustment outer switch 332 are not triggered, it indicates that the process of the lateral active adjustment units 221 and lateral driven adjustment units 222 adjusting their lateral positions is normal and can continue until the distance between the two lateral adjustment components 22 is suitable for the radial dimension of the casting 200.

[0140] Preferably, the two flexible magnetic strips of the lateral adjustment protective cover 2236 are bent from the upper end of the lateral adjustment walking support frame 22331 box groove towards the side of the lateral adjustment walking support frame 22331 box groove. The lateral adjustment inner switch 331 and the lateral adjustment outer switch 332 are respectively installed on the two sides of the lateral adjustment walking support frame 22331 box groove. The lateral adjustment inner switch 331 and the lateral adjustment outer switch 332 clamp the lateral adjustment protective cover 2236 from both sides and then fix it to the side wall of the lateral adjustment walking support frame 22331. The lateral adjustment switch assembly 33, while functioning as a proximity switch, also fixes the lateral adjustment protective cover 2236 to the side wall of the lateral adjustment walking support frame 22331, further preventing the lateral adjustment protective cover 2236 from falling off.

[0141] Preferably, each switch in the limiting component 3 is a proximity switch.

[0142] Example 2

[0143] Example 2 is a control method for a support system for sandblasting large cylindrical castings.

[0144] like Figure 11 As shown, a control method for a support system for sandblasting large cylindrical castings is provided, which is used to control the support system for sandblasting large cylindrical castings in Example 2 to perform sandblasting operations on casting 200.

[0145] A method for controlling a support system for sandblasting large cylindrical castings includes the following steps:

[0146] S1. Preparations:

[0147] S11. Adjusting the sandblasting machine:

[0148] Turn on the sandblasting machine and perform a pressure test until the sandblasting machine pressure is normal, then adjust the position of the sandblasting gun.

[0149] One or more sandblasting guns are provided.

[0150] S12. Prepare the sandblasting room:

[0151] Fill the sand pit in the sandblasting room with quartz sand;

[0152] S13. Preparation of a support system for sandblasting large cylindrical castings:

[0153] The casting 200 is hoisted onto two sets of lateral adjustment components 22. The power source 141 of the support vehicle is started, so that the support system for sandblasting of large cylindrical castings enters the sandblasting room along the track unit 11. The door of the sandblasting room is then closed.

[0154] The system includes a control terminal 100 that controls the longitudinal adjustment power source 211 and the lateral adjustment walking power source 2231, so that the distance between the two sets of lateral adjustment components 22 is adapted to the length of the casting 200, and the spacing between a pair of lateral active adjustment units 221 and lateral driven adjustment units 222 in the same group is adapted to the radial dimension of the cross-section of the casting 200, ensuring that the casting 200 is in a stable position on the lateral adjustment components 22, and even if the lateral adjustment rotation power source 2214 is activated to make the casting 200 rotate along its own axis, it can still be stably positioned on the lateral adjustment components 22.

[0155] S14. Prepare the control terminal 100:

[0156] Start the control terminal 100, and set the corresponding parameters of each power source and the parameters of the sandblasting gun according to the shape and size of the casting 200 and the position of the sandblasting gun, and plan the theoretical process of sandblasting the casting 200.

[0157] S2. Sandblasting of casting 200:

[0158] S21. Support system for sandblasting large cylindrical castings enters the work area:

[0159] The large cylindrical casting sandblasting support system with casting 200 moves forward along the track, and the overall longitudinal movement is activated by switch 311, indicating that the large cylindrical casting sandblasting support system has entered the working area.

[0160] S22. Sandblasting is performed on casting 200:

[0161] The control terminal 100 integrates the control of the sandblasting machine and the support system for sandblasting large cylindrical castings to perform sandblasting operations on casting 200;

[0162] The control terminal 100 starts the sandblasting machine and controls the support vehicle power source 141, the overall rotation power source 1321 and the lateral adjustment rotation power source 2214 according to the process set in section S14, so that the sandblasting machine can evenly spray the inner and outer surfaces of the casting 200.

[0163] The control terminal 100 controls the power source 141 of the support vehicle, the overall rotation power source 1321, and the lateral adjustment rotation power source 2214, including various controls such as starting, speed changing, pausing, reversing, and stopping. For example, the overall rotation power source 1321 can be set to pause for M minutes every N degrees of rotation, where N and M are finite positive numbers, such as N = 30 and M = 1.

[0164] S23. According to the settings, repeat S22 until the sandblasting of casting 22 is completed.

[0165] S3. Load and unload casting 200, preparing for the next sandblasting operation:

[0166] After completing the sandblasting operation on the previous casting 200, prepare to perform the sandblasting operation on the next casting 200;

[0167] S31. Determine whether the sandblasting operation of the previous casting 200 is completed:

[0168] When the overall movement longitudinal departure switch 312 is activated, the control terminal 100 first determines whether the sandblasting of the large cylindrical casting is complete:

[0169] Once completed, proceed to S32;

[0170] If not completed, reverse the start of the support vehicle power source 141 to return the large cylindrical casting sandblasting device to the entrance of the sandblasting room, and repeat S14 and S2.

[0171] S32. The sandblasting device for large cylindrical castings is moved out of the sandblasting room:

[0176] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto; any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
