[0002] When processing aluminum alloys, cutting fluids or lubricants are often used as auxiliary processing materials. Therefore, impurities such as cutting fluids, lubricants, and debris are usually left on the formed aluminum alloy parts. It is necessary to clean the impurities on the surface of the aluminum alloy parts.

[0003] In the related art, a cleaning device for aluminum alloy workpieces is designed, which includes a support frame and a water pump. A group of support platforms are symmetrically arranged on the support frame, and clamping claws are rotatably arranged on the support platforms. A motor is fixedly arranged on the support platform, and the driving shaft of the motor is coaxially fixed with the clamping claws. A lifting frame is fixedly arranged on the base, and a sprinkler nozzle is installed on the lifting frame. The sprinkler nozzle and the water pump are connected to each other. When cleaning the aluminum alloy workpiece, the water pump is placed in the flushing liquid, one end of the workpiece is clamped on one of the clamping claws, and the other end of the workpiece is clamped on the other clamping claw. The flushing liquid is extracted by the water pump and transported to the sprinkler nozzle. The sprinkler nozzle sprays the flushing liquid on the workpiece. In this process, the clamping claws are driven to rotate by the motor, thereby continuously driving the workpiece to flip, and different positions of the workpiece are flushed.

[0004] In the process of implementing the present application, it was found that there are at least the following problems in this technology: First, when the structure of the aluminum alloy workpiece is complex or the cross-sectional shape is special, it is difficult for the clamp to exert a clamping force on the workpiece, so that the workpiece cannot be clamped up, and it is inconvenient to turn over the workpiece; second, the position where the workpiece is clamped by the clamp is always blocked by the clamp, resulting in a blind spot for flushing. Summary of the invention

[0005] In order to facilitate turning over the aluminum alloy workpieces when flushing and cleaning them and to avoid obstruction of the workpieces as much as possible, the present application provides an aluminum alloy workpiece cleaning device.

[0006] The present application provides an aluminum alloy workpiece cleaning device that adopts the following technical solution: The cam is an air-conditioner which is provided with a plurality of upper and lower connecting frames, and the upper and lower connecting frames are provided with a plurality of lower connecting frames respectively. The cam is provided with a plurality of lower connecting frames, and the upper and lower connecting frames are provided with a plurality of upper and lower connecting frames respectively. The cam is provided with a plurality of lower connecting frames respectively. The plurality of upper and lower connecting frames are provided with a plurality of lower connecting frames respectively.

[0007] By adopting the above technical scheme, when the aluminum alloy workpiece needs to be cleaned, the workpiece is first placed on the flipping belt between the two first rotating rollers, and the flipping belt is pressed down by the workpiece to form a depression and tightened; the flipping belt at the depression holds the workpiece and deforms with the bottom shape of the workpiece, and the flipping belt covers the bottom of the workpiece; then the water pump is started, the water pump extracts the flushing liquid and transports it to the sprinkler nozzle, and the sprinkler nozzle sprays the flushing liquid on the workpiece located in the depression, so as to flush the top of the workpiece; in this process, the two first rotating rollers are driven to rotate in the same direction by the rotating component, and at this time the inner surface of the flipping belt rubs against the peripheral wall of the first rotating roller, and one of the first The rotating roller releases the flipping belt toward the direction of the pit, and the other first rotating roller retracts the flipping belt toward the direction of the pit. The flipping belt at the pit covers the bottom of the workpiece and changes the moving direction at the same time to force the workpiece to flip, thereby flushing different positions of the workpiece. In summary, the bottom of the workpiece is covered by the deformation of the flipping belt to realize the flipping action of the workpiece. The cleaning device has strong adaptability to the shape of the workpiece, which is convenient for flipping workpieces with different cross-sectional shapes, and there is no need to clamp the workpiece, which is convenient for flipping workpieces with complex structures. In addition, in the process of flushing the workpiece, no part of the workpiece is always blocked by the cleaning device, thereby reducing the blind spots in flushing.

[0008] Preferably, the rotating assembly includes a belt transmission mechanism and a driving motor, the belt transmission mechanism is arranged in two groups, the belt transmission mechanism includes a driving pulley, a driven pulley and a transmission belt, the transmission belt is arranged for transmission between the driving pulley and the driven pulley, one end of the transmission belt is sleeved on the driving pulley, and the other end of the transmission belt is sleeved on the driven pulley; the driving motor is fixedly arranged in the center of the side wall of the support frame, and the driving shaft of the driving motor is coaxially fixed to the driving pulleys of the two belt transmission mechanisms at the same time, one of the driven pulleys of the belt transmission mechanism is coaxially fixed to one of the first rotating rollers, and the other driven pulley of the belt transmission mechanism is coaxially fixed to the other first rotating roller.

[0009] By adopting the above technical solution, in the belt transmission structure, the driving pulley transmits the rotational motion to the driven pulley through the transmission belt, and the rotation direction of the driven pulley is consistent with that of the driving pulley. When it is necessary to drive the two first rotating rollers to rotate in the same direction, the driving motor is started, and the driving shaft of the driving motor drives the driving pulleys of the two belt transmission mechanisms to rotate at the same time. Since the two driving pulleys are coaxially fixed with the driving motor, the rotation directions of the two driving pulleys are consistent, and the rotation directions of the two transmission pulleys are also consistent, and the two first rotating rollers are driven to rotate in the same direction. In addition, since the driving motor is fixed in the center of the support frame, the two transmission belts are inclined toward the center of the support frame, which minimizes the interference of the transmission belts on the placement of the workpiece.

[0010] Preferably, the driving motor is a waterproof motor.

[0011] By adopting the above technical solution, since the driving motor is fixed in the center of the support frame, the flushing liquid may spread along the support frame and contact the driving motor.

[0012] Preferably, a supporting arm is provided on the upper connecting frame, and a pressure wheel is rotatably provided on the top end of the supporting arm, and the pressure wheel presses the flipping belt onto the first rotating roller.

[0015] By adopting the above technical solution, the torsion spring applies a torsional force to the support arm, driving the pressure wheel to approach the flipping belt. The torsion spring applies the torsional force to the pressure wheel through the support arm, further ensuring the pressure between the first rotating roller and the flipping belt. In addition, the support arm can be lifted to move the pressure wheel away from the flipping belt, thereby reducing the friction between the flipping belt and the first rotating roller, so as to adjust the length of the flipping belt between the two first rotating rollers, thereby adjusting the degree of coverage of the bottom of the workpiece by the flipping belt at the pit.

[0017] By adopting the above technical scheme, when it is necessary to change the covering degree of the bottom of the workpiece by the flipping belt, the double-threaded screw is driven to rotate, the double-threaded screw meshes and drives one of the lower connecting frames to slide, and at the same time meshes and drives the other lower connecting frame to slide in the opposite direction, thereby driving the two lower connecting frames to approach or move away from each other. When the two lower connecting frames approach each other, the spacing between the two second rotating rollers decreases, the length of the flipping belt between the two first rotating rollers increases, the angle on both sides of the pit decreases, and the covering degree of the bottom of the workpiece by the flipping belt is improved. When the two lower connecting frames move away from each other, the angle on both sides of the pit increases, and the covering degree of the bottom of the workpiece by the flipping belt is reduced, but the height position of the workpiece rises, which is closer to the sprinkler nozzle, and the flushing force of the flushing liquid on the surface of the workpiece is stronger.

[0018] Preferably, a lever is fixedly provided on the torsion shaft on the side close to the knob.

[0019] By adopting the above technical solution, when it is necessary to change the degree of coverage of the bottom of the workpiece by the flipping belt, the staff can be on one side of the device, press the lever with one hand to drive the pressure wheel away from the flipping belt, and turn the knob with the other hand to drive the two lower connecting frames closer to or away from each other, so as to facilitate single-person operation and change the degree of coverage of the bottom of the workpiece by the flipping belt.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application discloses a cleaning device for aluminum alloy workpieces. Figure 1 and Figure 2 , which includes a support frame 22, a water pump 21, and a water reservoir 2. The support frame 22 is four vertical and fixed columns installed in the center of the water reservoir 2, and a support frame 1 is fixedly arranged on the top of the support frame 22, and the support frame 1 is arranged horizontally. The water pump 21 is arranged in the water reservoir 2.

[0033] Reference Figure 1 A group of upper connecting frames 11 are symmetrically and fixedly arranged on the upper surface of the support frame 1, and a first rotating roller 111 is rotatably arranged on each upper connecting frame 11. A group of lower connecting frames 12 are arranged in the support frame 1, and a second rotating roller 121 is rotatably arranged on each lower connecting frame 12. The first rotating roller 111 is higher than the second rotating roller 121 and is parallel to the axis of the second rotating roller 121. A flipping belt 13 is arranged between the first rotating roller 111 and the second rotating roller 121, and the flipping belt 13 passes through the two first rotating rollers 111 and the two second rotating rollers 121 at the same time. The flipping belt 13 is pressed down by the workpiece between the two first rotating rollers 111 to form a sink 131.

[0034] Reference Figure 1 and Figure 2 A sprinkler head 3 is also provided on the support frame 1. The sprinkler head 3 is connected with the water pump 21. The sprinkler head 3 is directly opposite to the center of the pit 131. A rotating component 4 is also provided on the support frame 1. The rotating component 4 is used to drive the two first rotating rollers 111 to rotate in the same direction. The inner surface of the flipping belt 13 is frictionally connected with the peripheral wall of the first rotating roller 111.

[0035] Reference Figure 1 and Figure 2, the workpiece is placed on the flipping belt 13 between the two first rotating rollers 111. Due to the gravity of the workpiece, a pit 131 is formed on the flipping belt 13 and is tightened by the workpiece. The water pump 21 extracts the flushing liquid from the water reservoir 2 and transports it to the sprinkler 3. The sprinkler 3 is aimed at the workpiece in the center of the pit 131 to flush the workpiece. The two first rotating rollers 111 are driven to rotate in the same direction through the rotating component 4, one of the first rotating rollers 111 releases the flipping belt 13 in the direction of the pit 131, and the other first rotating roller 111 contracts the flipping belt 13 in the direction of the pit 131. The flipping belt 13 at the pit 131 covers the bottom of the workpiece and applies a torque to the workpiece, thereby driving the workpiece to roll over, so as to flush different positions of the workpiece. The cleaning device can flip workpieces with different cross-sectional shapes or complex structures without clamping the workpiece. In addition, during the flushing process of the workpiece, the workpiece is not blocked by the cleaning device, thus reducing the flushing dead angle. After flushing the workpiece, the flushing liquid falls into the water reservoir 2 below the workpiece, thus improving the utilization rate of the flushing liquid and saving resources.

[0036] In order to drive the two first rotating rollers 111 to rotate in the same direction, refer to Figure 3 The rotating assembly 4 includes a belt transmission mechanism and a driving motor 42. The driving motor 42 is a waterproof motor, which can work normally in a humid environment, thereby ensuring the stable operation of the cleaning device during the flushing process. The belt transmission mechanism is set into two groups, and the specifications of the two groups of belt transmission mechanisms are completely consistent. The belt transmission mechanism specifically includes a driving pulley 411, a driven pulley 412, and a transmission belt 413. The transmission belt 413 is arranged for transmission between the driving pulley 411 and the driven pulley 412, one end of the transmission belt 413 is sleeved on the driving pulley 411, and the other end of the transmission belt 413 is sleeved on the driven pulley 412. In the belt transmission structure, the driving pulley 411 transmits the rotational motion to the driven pulley 412 through the transmission belt 413, and the rotation direction of the driven pulley 412 is consistent with that of the driving pulley 411.

[0037] Reference Figure 3 The driving motor 42 is fixedly arranged in the center of the side wall of the support frame 1, and the driving shaft of the driving motor 42 is coaxially fixed with the driving pulleys 411 of the two sets of belt transmission mechanisms. The driven pulley 412 of one belt transmission mechanism is coaxially fixed with one of the first rotating rollers 111, and the driven pulley 412 of the other belt transmission mechanism is coaxially fixed with the other first rotating roller 111.

[0038] Reference Figure 3The driving shaft of the driving motor 42 drives the driving pulleys 411 of the two belt transmission mechanisms to rotate at the same time. Since the two driving pulleys 411 are coaxially fixed with the driving motor 42, the rotation directions of the two driving pulleys 411 are consistent, and the rotation directions of the two transmission belts 413 are also consistent, and the two first rotating rollers 111 are driven to rotate in the same direction. In addition, since the driving motor 42 is fixedly arranged in the center of the support frame 1, the two transmission belts 413 are inclined toward the center of the support frame 1, and the transmission belts 413 are avoided as much as possible from contacting the workpiece.

[0039] In order to avoid slipping between the first rotating roller 111 and the flipping belt 13 as much as possible, refer to Figure 1 , a supporting arm 14 is provided on the upper connecting frame 11, and a pressure wheel 141 is rotatably provided on the top of the supporting arm 14. A torsion shaft 142 is fixedly provided at the bottom end of the supporting arm 14, and the torsion shaft 142 is hingedly matched with the upper connecting frame 11. A torsion spring is provided at the connection between the torsion shaft 142 and the upper connecting frame 11, and the torsion spring drives the pressure wheel 141 to approach the flipping belt 13. The pressure wheel 141 presses the flipping belt 13 against the first rotating roller 111. The torsion spring applies a torsional force to the supporting arm 14, driving the pressure wheel 141 to approach the flipping belt 13, and the pressure wheel 141 abuts against the outer surface of the flipping belt 13. The flipping belt 13 is pressed against the first rotating roller 111, the pressure between the first rotating roller 111 and the flipping belt 13 is increased, and the slippage between the first rotating roller 111 and the flipping belt 13 is avoided as much as possible.

[0040] In order to adjust the degree of covering of the bottom of the workpiece by the turning belt 13, refer to Figure 1 , the lower connecting frame 12 is slidably connected with the support frame 1. A retaining frame 15 is fixedly arranged on the outer side of the support frame 1, and a double-threaded screw 151 is rotatably arranged on the retaining frame 15. The two thread segments of the double-threaded screw 151 have opposite rotation directions and equal pitches. One thread segment of the double-threaded screw 151 is threadedly engaged with one of the lower connecting frames 12, and the other thread segment of the double-threaded screw 151 is threadedly engaged with the other lower connecting frame 12. The end of the double-threaded screw 151 passes through the retaining frame 15 and is fixedly arranged with a knob 152. A lever 1421 is fixedly arranged on the torsion shaft 142 near the knob 152.

[0041] Reference Figure 1, the staff member on one side of the device presses down the lever 1421 with one hand, and the lever 1421 drives the supporting arm 14 to overcome the torsion force of the torsion spring, so that the pressure wheel 141 moves away from the flipping belt 13, and the friction between the flipping belt 13 and the first rotating roller 111 is reduced, which facilitates the flipping belt 13 and the first rotating roller 111 to slip. The staff member turns the knob 152 with the other hand, and the knob 152 drives the double-threaded screw 151 to rotate, and the double-threaded screw 151 meshes and drives the two lower connecting frames 12 to move closer to or away from each other. When the two lower connecting frames 12 move closer to each other, the distance between the two second rotating rollers 121 decreases, the length of the flipping belt 13 between the two first rotating rollers 111 increases, the angle between the two sides of the pit 131 decreases, and the degree of coverage of the bottom of the workpiece by the flipping belt 13 increases. When the two lower connecting frames 12 move away from each other, the angle between the two sides of the pit 131 increases, and the coverage of the bottom of the workpiece by the turning belt 13 decreases, but the height of the workpiece rises and is closer to the sprinkler head 3, so the flushing pressure of the flushing liquid on the surface of the workpiece is higher. This makes it easier for a single person to operate and change the coverage of the bottom of the workpiece by the turning belt 13.

[0042] In order to avoid the collision of the workpiece with the sprinkler head 3 during the replacement of the workpiece, refer to Figure 1 , a first bracket 16 is fixedly arranged on the top of one upper connecting frame 11, and a second bracket 17 is fixedly arranged on the top of the other upper connecting frame 11. A suspension frame 161 is hingedly arranged on the top of the first bracket 16, and the end of the suspension frame 161 away from the first bracket 16 can be against the top of the second bracket 17. A suspension rod 162 is vertically and fixedly arranged at the center of the bottom of the suspension frame 161, and the bottom of the suspension rod 162 is fixedly connected to the sprinkler head 3. The sprinkler head 3 is connected to the water pump 21 through a hose 31.

[0043] Reference Figure 1 When the workpiece needs to be replaced, the suspension bracket 161 is first lifted, the suspension bracket 161 is separated from the second support block 17, and rotates around the second support block, so that the sprinkler head 3 is pulled out from the position of the pit 131, so that the sprinkler head 3 is far away from the position of the pit 131, and the workpiece is prevented from colliding with the sprinkler head 3 during the replacement process, causing damage to the sprinkler head 3.

[0044] The implementation principle of the aluminum alloy workpiece cleaning device of the embodiment of the present application is as follows: when cleaning the aluminum alloy workpiece, the staff first lifts the suspension frame 161 and pulls the sprinkler head 3 out from above the pit 131. After placing the workpiece on the flipping belt 13 between the two first rotating rollers 111, the suspension frame 161 is lowered. The flipping belt 13 is pressed down by the workpiece and tightened. The flipping belt 13 at the pit 131 supports the workpiece and deforms with the bottom shape of the workpiece to cover the bottom of the workpiece.

[0045] Then the staff member presses the lever 1421 with one hand to move the pressure wheel 141 away from the flipping belt 13, and turns the knob 152 with the other hand to adjust the distance between the two lower connecting frames 12. When the two lower connecting frames 12 are close to each other, the degree of covering the bottom of the workpiece by the flipping belt 13 is improved. When the two lower connecting frames 12 are away from each other, the workpiece is closer to the sprinkler head 3.

[0046] Then start the water pump 21 and the drive motor 42. The water pump 21 extracts the flushing liquid from the water reservoir 2 and delivers it to the sprinkler 3. The sprinkler 3 flushes the workpiece. The drive motor 42 drives the two active pulleys 411 to rotate, and drives the two first rotating rollers 111 to rotate in the same direction through the transmission belt 413 and the driven pulley 412. One of the first rotating rollers 111 releases the flipping belt 13 in the direction of the pit 131, and the other first rotating roller 111 contracts the flipping belt 13 in the direction of the pit 131. The flipping belt 13 at the pit 131 covers the bottom of the workpiece and applies torque to the workpiece, thereby driving the workpiece to roll, so as to flush different positions of the workpiece. The cleaning device can flip the workpiece with different cross-sectional shapes or complex structures without clamping the workpiece. In addition, during the flushing process of the workpiece, the workpiece is not always blocked by the cleaning device, which reduces the flushing dead angle. After flushing the workpiece, the flushing liquid falls into the water reservoir 2 below the workpiece, thereby improving the utilization rate of the flushing liquid and saving resources.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
