[0051] Based on the background technology, the shell of mechanical equipment is usually composed of two halves connected by screws, and multiple threaded holes need to be processed in the shell to fix various parts. For the shell of a casting, after multiple processing steps, the processed threaded holes will have residual metal debris and processing liquid, and the holes need to be cleaned to meet the acceptance standards. The commonly used screw hole cleaning method is to manually hold a spray nozzle and blow air to clean each screw hole one by one. The disadvantage of this method is that the cleaning speed is slow, the labor intensity of the operator is increased, and for workpieces with a large number of screw holes, it is very easy to cause omissions, which affects the service life of the equipment.

[0052] In view of this, the present application provides a screw hole cleaning device to solve the problem that the screw hole cleaning speed is slow and it is very easy to cause omissions, thereby increasing the labor intensity of the operator.

[0053] Combination Figure 1-Figure 3 As shown, the screw hole cleaning device 100 provided in the embodiment of the present application includes a frame 10, a conveying mechanism 20, a blowing mechanism 30, a lifting mechanism 40, a positioning mechanism 50, a fixing mechanism 60, a sensing mechanism 70 and a blocking mechanism 80.

[0054] Specifically, the conveying mechanism 20 is arranged on the frame 10, and the conveying mechanism 20 is used to convey the workpiece 1 having multiple screw holes. For example, the conveying mechanism 20 includes an assembly line. The blowing mechanism 30 includes a blowing assembly 31, a mounting plate 32 and a plurality of blowing needles 33. The mounting plate 32 is arranged on the frame 10 and is located above the conveying mechanism 20. The blowing assembly 31 is connected to the plurality of blowing needles 33. The plurality of blowing needles 33 are arranged on the mounting plate 32 and face the conveying mechanism 20. The blocking mechanism 80 includes a first driving member 81 and a stopper 82. For example, the first driving member 81 includes a driving cylinder. The first driving member 81 is arranged on the frame 10. The first driving member 81 drives the stopper 82 to rise relative to the frame 10, so that the stopper 82 blocks the workpiece 1. The lifting mechanism 40 is arranged on the frame 10 and is located below the conveying mechanism 20. The lifting mechanism 40 is used to push the workpiece 1 to rise relative to the frame 10, so that each of the multiple blowing needles 33 is respectively inserted into each of the multiple screw holes. The blowing assembly 31 provides an air source for the multiple blowing needles 33, so that the multiple blowing needles 33 blow air to the multiple screw holes on the workpiece 1.

[0055] It should be noted that the distribution positions of the plurality of blowing needles 33 on the mounting plate 32 correspond one-to-one to the distribution positions of the plurality of screw holes on the workpiece 1 .

[0056] In the above embodiment, in the initial state of the screw hole cleaning device 100, the block 82 is in a raised state, that is, the block 82 can block the workpiece 1 located at the conveying mechanism 20. First, the workpiece 1 is conveyed along the first direction X by the conveying mechanism 20, without the need for manual handling, and the transportation efficiency is high; then, the workpiece 1 is blocked from continuing to move by the block 82, so that it can be ensured that the workpiece 1 has been transported to the bottom of the blowing mechanism 30, which is convenient for the subsequent blowing mechanism 30 to blow air; then, the workpiece 1 is pushed up along the second direction Z by the lifting mechanism 40, so that each of the multiple blowing needles 33 is respectively inserted into each of the multiple screw holes, without the need for manual placement of the workpiece 1; finally, the blowing assembly 31 provides an air source for the multiple blowing needles 33, so that each blowing needle 33 blows air to the corresponding screw hole, thereby cleaning each screw hole, and adopts a one-to-one cleaning method, so that there will be no cleaning omission problem. Based on this, the present application realizes automated cleaning operations, with high cleaning efficiency, good cleaning effect, and low labor costs. In addition, this application is also compatible with assembly line conveying operations and is highly practical.

[0057] In one embodiment of the present application, the blowing assembly 31 includes a gas pipe joint 311 and a gas cylinder (not shown). The gas pipe joint 311 is mounted on a mounting plate 32. A gas flow channel (not shown) is provided in the mounting plate 32, the gas flow channel is connected to a plurality of blowing needles 33, and the gas pipe joint 311 is connected to the gas flow channel. The gas pipe joint 311 is connected to the gas cylinder through an air inlet pipe. Gas is stored in the gas cylinder.

[0058] In the above embodiment, by arranging the air pipe joint 311 on the mounting plate 32, it is convenient to connect to the air source, easy to disassemble, and highly flexible.

[0059] In one embodiment of the present application, the screw hole cleaning device 100 further includes a positioning mechanism 50. The positioning mechanism 50 is installed on a side of the stopper 82 close to the blowing mechanism 30. The positioning mechanism 50 is used to sense the position of the workpiece 1.

[0060] In one embodiment of the present application, the workpiece 1 is made of metal, and the positioning mechanism 50 is a metal sensor.

[0061] In one embodiment of the present application, the positioning mechanism 50 is a rod-shaped structure, and passes through the stopper 82 along the first direction X.

[0062] In the above embodiment, when the conveying mechanism 20 is conveying the workpiece 1 and the positioning mechanism 50 contacts the workpiece 1, it is determined that the conveying mechanism 20 has conveyed the workpiece 1 to directly below the blowing mechanism 30 without manual confirmation, and the degree of automation is high.

[0063] In one embodiment of the present application, the screw hole cleaning device 100 further includes two fixing mechanisms 60. The two fixing mechanisms 60 are disposed on the frame 10 and are located below the blowing mechanism 30. The two fixing mechanisms 60 are respectively distributed on both sides of the conveying mechanism 20 and are movable relative to the conveying mechanism 20 to clamp the workpiece.

[0064] In the above embodiment, after each of the multiple blow needles 33 is respectively inserted into each of the multiple screw holes on the workpiece 1, the two fixing mechanisms 60 clamp the workpiece 1 from both sides of the workpiece 1, so that the workpiece 1 remains fixed during the blowing process of the multiple blow needles 33, thereby preventing the blow needles 33 from colliding with the workpiece 1 and causing damage to the workpiece 1.

[0065] In one embodiment of the present application, the screw hole cleaning device 100 further includes a sensing mechanism 70. The sensing mechanism 70 is installed on a side of the stopper 82 away from the blowing mechanism 30. The sensing mechanism 70 is used to sense the position of the workpiece.

[0066] In one embodiment of the present application, the sensing mechanism 70 may include an infrared sensor, which determines the position of the workpiece 1 by emitting infrared rays and measuring reflected infrared signals.

[0067] In the above embodiment, when the sensing mechanism 70 senses the workpiece 1, it is determined that the conveying mechanism 20 has transported the workpiece 1 from under the blowing mechanism 30, that is, the conveying mechanism 20 has transported the workpiece 1 from the side of the stopper 82 close to the blowing mechanism 30 to the side of the stopper 82 away from the blowing mechanism 30, without the need for manual confirmation, and the degree of automation is high.

[0068] In one embodiment of the present application, the frame 10 includes a fixing plate 11 and a plurality of support columns 12. The fixing plate 11 is mounted on the frame 10 and is located below the conveying mechanism 20. The plurality of support columns 12 are disposed on the peripheral side of the fixing plate 11. The mounting plate 32 is mounted on the ends of the plurality of support columns 12 opposite to the fixing plate 11.

[0069] In the above embodiment, a plurality of support columns 12 are disposed at the four corners of the fixing plate 11 , which can more stably support the mounting plate 32 and ensure that the mounting plate 32 can more stably carry the plurality of blowing needles 33 .

[0070] In one embodiment of the present application, the fixing mechanism 60 includes a second driving member 61 and a fixing assembly 62. The second driving member 61 is mounted on the frame 10. For example, the second driving member 61 includes a driving cylinder. The fixing assembly 62 is connected to the second driving member 61. The fixing assembly 62 extends from the side of the conveying mechanism 20 and is located below the mounting plate 32. The second driving member 61 drives the fixing assembly 62 to move relative to the conveying mechanism 20.

[0071] In the above embodiment, the second driving member 61 is installed on the side of the fixed plate 11 facing the conveying mechanism 20. The second driving members 61 on both sides of the conveying mechanism 20 drive the corresponding fixing components 62 to approach the conveying mechanism 20, clamp the workpiece 1, so that the workpiece 1 remains fixed, thereby preventing the blowing needle 33 from colliding with the workpiece 1 and causing damage to the workpiece 1.

[0072] In one embodiment of the present application, the lifting mechanism 40 includes a third driving member 41, a lifting top plate 42 and a plurality of support blocks 43. For example, the third driving member 41 may include a lifting cylinder. The third driving member 41 is mounted on the frame 10. The lifting top plate 42 is connected to the third driving member 41. A plurality of support blocks 43 are arranged on a side of the lifting top plate 42 facing the conveying mechanism 20, and a plurality of support blocks 43 are distributed on both sides of the lifting top plate 42. The third driving member 41 is used to drive the lifting top plate 42 to rise relative to the conveying mechanism 20, so that the lifting top plate 42 drives the plurality of support blocks 43 to extend from the conveying mechanism 20 and push the workpiece 1 close to the mounting plate 32.

[0073] In the above embodiment, after the conveying mechanism 20 has conveyed the workpiece 1 to the bottom of the blowing mechanism 30, the third driving member 41 drives the lifting top plate 42 to rise along the second direction Z, so that the lifting top plate 42 drives the plurality of support blocks 43 to extend from the conveying mechanism 20 along the second direction Z and push the workpiece 1 close to the mounting plate 32, so that each of the plurality of blowing needles 33 is respectively inserted into each of the plurality of screw holes on the workpiece 1. Since the workpiece 1 is relatively thin, the plurality of support blocks 43 can support the workpiece 1, preventing the problem of deformation of the workpiece 1 caused by excessive blowing force of the blowing needle 33 when blowing the screw holes of the workpiece 1. In addition, when the lifting top plate 42 contacts the conveying mechanism 20, it indicates that each of the multiple blow needles 33 has been respectively inserted into each of the multiple screw holes on the workpiece 1, and the third driving member 41 stops driving. Based on this, the lifting top plate 42 limits the third driving member 41, preventing the third driving member 41 from driving the lifting top plate 42 to rise along the second direction Z, causing the blow needle 33 to touch the workpiece 1 and cause damage to the workpiece 1.

[0074] In one embodiment of the present application, the fixing assembly 62 includes a connecting plate 621 and a plurality of fixing blocks 622. The connecting plate 621 is movably disposed on the frame 10 and connected to the second driving member 61. The plurality of fixing blocks 622 are mounted on the connecting plate 621. The plurality of fixing blocks 622 extend from the side of the conveying mechanism 20 along the second direction Z and are located directly below the mounting plate 32.

[0075] In the above embodiment, after the lifting mechanism 40 pushes the workpiece 1 to rise, the second driving members 61 on both sides of the conveying mechanism 20 respectively drive the corresponding connecting plates 621 to move toward the direction close to the workpiece 1, so that the connecting plates 621 on both sides of the conveying mechanism 20 drive multiple fixing blocks 622 to clamp the workpiece 1 from both sides of the workpiece 1 to fix the workpiece 1, thereby preventing the blowing needle 33 from colliding with the workpiece 1 and causing damage to the workpiece 1 when blowing air into the screw hole of the workpiece 1.

[0076] In one embodiment of the present application, the screw hole cleaning device 100 further includes an electric control box (not shown). The electric control box is respectively connected to the conveying mechanism 20, the blowing mechanism 30, the lifting mechanism 40, the positioning mechanism 50, the fixing mechanism 60, the sensing mechanism 70 and the blocking mechanism 80, and sends control signals to the conveying mechanism 20, the blowing mechanism 30, the lifting mechanism 40, the positioning mechanism 50, the fixing mechanism 60, the sensing mechanism 70 and the blocking mechanism 80.

[0077] Specifically, in the initial state of the screw hole cleaning device 100, the block 82 is in a raised state, that is, the block 82 can block the workpiece 1 located at the conveying mechanism 20. First, the electric control box sends an opening signal to the conveying mechanism 20, and the conveying mechanism 20 starts to convey the workpiece 1 along the first direction X based on the opening signal; then, when the positioning mechanism 50 contacts the workpiece 1, it sends a trigger signal to the electric control box, and the electric control box determines based on the trigger signal that the conveying mechanism 20 has conveyed the workpiece 1 to the bottom of the blowing mechanism 30, and sends a stop signal to the conveying mechanism 20, and the conveying mechanism 20 stops conveying the workpiece 1 based on the stop signal; then, the electric control box sends a lifting signal to the lifting mechanism 40, and the third driving member 41 drives the lifting top plate 42 to rise along the second direction Z, and the lifting top plate 42 contacts the conveyor When the conveying mechanism 20 is in the state of being moved, the third driving member 41 stops driving, so that the lifting top plate 42 drives the plurality of supporting blocks 43 to extend from the conveying mechanism 20 along the second direction Z and push the workpiece 1 close to the mounting plate 32, so that each of the plurality of blowing needles 33 is respectively inserted into each of the plurality of screw holes on the workpiece 1 and does not touch the workpiece 1; then, the electric control box sends a clamping signal to the two fixing mechanisms 60, and the second driving members 61 on both sides of the conveying mechanism 20 drive the corresponding fixing components 62 to approach the conveying mechanism 20 based on the clamping signal to clamp the workpiece 1; then, the blowing mechanism 30 of the electric control box sends The blowing signal causes each blowing needle 33 to intermittently blow air to the corresponding screw hole (blowing for 0.5 seconds and stopping for 0.5 seconds, and blowing when needed), which is conducive to blowing out foreign matter, and stops blowing after a preset time; then, the electric control box sends a reset signal to the fixing mechanism 60 and the lifting mechanism 40 in turn, and at the same time sends a descending signal to the blocking mechanism 80, and the second driving members 61 on both sides of the conveying mechanism 20 drive the corresponding fixing components 62 away from the conveying mechanism 20, release the workpiece 1, and the third driving member 41 drives the lifting top plate 42 to descend, so that the workpiece 1 is placed back on the conveying mechanism 20, and the first driving member 81 drives the stopper 8 2 descends to the bottom of the conveying mechanism 20, then, the electric control box sends an opening signal to the conveying mechanism again, and the conveying mechanism 20 continues to convey the workpiece 1 based on the opening signal. Then, when the sensing mechanism 70 senses the workpiece 1, the sensing signal is triggered. Based on the sensing signal, the electric control box determines that the conveying mechanism 20 has transported the workpiece 1 from the side of the stopper 82 close to the blowing mechanism 30 to the side of the stopper 82 away from the blowing mechanism 30. Then, the electric control box sends a reset signal to the blocking mechanism 80, and the first driving member 81 drives the stopper 82 to rise along the second direction Z and extend from the conveying mechanism 20 to block the next workpiece 1 to be cleaned.

[0078] In the above embodiment, the cleaning process of the screw hole cleaning device 100 is centrally controlled by the electric control box to realize automated cleaning operation with high cleaning efficiency.
