Description

Technical Field

[0002] The piston sleeve, also known as the cylinder sleeve, is a hollow metal structure used to provide guidance for the movement of the piston (such as a hydraulic push cylinder sleeve). The piston sleeve is a sheet metal part made of metal sheets by punching, bending and welding.

[0003] During the cylinder liner processing, the sleeve needs to be cleaned after turning and grinding to remove the adhered impurities inside the sleeve. In the prior art, ultrasonic cleaning is generally used. However, when cleaning a large sleeve, the impurities are always located on the inner wall of the sleeve after being cleaned, and it is impossible to ensure that the impurities in the sleeve are effectively discharged. Therefore, in response to this situation, a brushing method has emerged. The brushing method uses the reciprocating movement of the cleaning brush and the spraying of water to clean the impurities attached to the inner wall of the sleeve. However, this method is relatively inefficient, and the spraying of water will cause serious water stains in the working area. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 to Figure 4 In an embodiment of the utility model, a cleaning device for sheet metal processing includes a workbench 1, a sliding clamping mechanism penetrating the inner side of the workbench 1 is installed above the workbench 1, the sliding clamping mechanism is used to clamp the sleeve moved to the cleaning position, a water circulation mechanism is installed below the workbench 1, the input end and the output end of the water circulation mechanism are aligned with the inlet hole and the outlet hole of the sleeve moved to the cleaning position in the up and down directions; a cleaning mechanism for cleaning the inner wall of the sleeve is installed on one side of the workbench 1, and a connecting platform 14 is fixedly connected to one side of the workbench 1 below the cleaning mechanism; a power mechanism for driving the cleaning mechanism to move is installed on the top of the connecting platform 14.

[0028] In this embodiment: when cleaning the hydraulic push cylinder sleeve after turning, the sleeve is placed on the lower half of the clamping mechanism, and then the lower half of the clamping mechanism is pushed to move to just below the upper half of the clamping mechanism, and then the sleeve is clamped to achieve position limitation of the sleeve;

[0029] Then the water circulation mechanism is docked with the inlet and outlet holes of the sleeve. After the docking is completed, the driving mechanism is started, and the driving mechanism drives the cleaning mechanism to move. The cleaning mechanism closes the open end of the sleeve. Then the water circulation mechanism and the cleaning mechanism are started to clean the inner wall of the sleeve.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3The clamping mechanism includes a No. 1 cylinder 4 installed on the top of the top plate of the workbench 1. The output end of the No. 1 cylinder 4 is connected to two upper clamping plates 5 through a connecting plate. The two upper clamping plates 5 are symmetrically distributed at the bottom end of the connecting plate; the clamping mechanism also includes a sliding seat 2 slidably connected to the top of the bottom plate of the workbench 1. The top of the sliding seat 2 is symmetrically fixedly connected to two lower clamping plates 3. The inner sides of the upper clamping plates 5 and the lower clamping plates 3 are both formed with "V"-shaped grooves that contact the outer wall of the sleeve.

[0031] In this embodiment: the sleeve is placed on the lower clamping plate 3, and the outlet hole and the inlet hole of the sleeve are directly below, and then the sliding seat 2 is pushed to slide to the bottom of the No. 1 cylinder 4, and the No. 1 cylinder 4 drives the two upper clamping plates 5 to move downward through the connecting plate, and the upper clamping plates 5 cooperate with the lower clamping plates 3 to clamp the sleeve, so that the sleeve is limited to the cleaning position. After the sliding seat 2 moves to the cleaning position, the through hole 6 on the sliding seat 2 coincides with the through hole 6 on the workbench 1;

[0032] Due to the "V"-shaped grooves in the upper clamping plate 5 and the lower clamping plate 3, and the upper clamping plate 5 and the lower clamping plate 3 are offset, sleeves with different diameters can be clamped.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The water circulation mechanism includes a through hole 6 opened inside the lower clamping plate 3 and inside the bottom end plate of the workbench 1. The bottom of the bottom end plate of the workbench 1 is fixedly connected to a limit ring 7. The bottom end of the limit ring 7 is formed with a hollow ring structure. The inner wall of the hollow ring structure is slidably connected with a moving tube 8. The two moving tubes 8 are synchronously connected through a synchronization rod 11. A No. 2 cylinder 12 is installed at the bottom of the bottom end plate of the workbench 1. The output end of the No. 2 cylinder 12 is connected to the top center of the synchronization rod 11; the moving tube 8 is aligned with the lower clamping plate 3 on the workbench 1 on the up and down directions, and the bottom end of the moving tube 8 is connected with a bellows 9, which is connected to a water pump 10. One water pump 10 is an input device and the other water pump 10 is an output device. The outer wall of the moving tube 8 is formed with a first sealing plate, and a sealing ring is fixedly connected to the top of the first sealing plate.

[0034] In this embodiment: after the sleeve is fixed, the second cylinder 12 is started, and the second cylinder 12 drives the moving tube 8 to move upward through the synchronization rod 11, and the bellows 9 is stretched at the same time. In this process, the top of the moving tube 8 is inserted into the inlet and outlet holes of the sleeve until the first sealing plate is effectively against the bottom end surfaces of the outlet and inlet holes, at which time the sealing ring is squeezed and deformed to achieve effective sealing;

[0035] After the opening at one end of the sleeve is also closed, the water pump 10 serving as an input device is started first. The output end of the water pump 10 is connected to the clean water tank through a pipe, and water is input into the sleeve. When the input is completed, the two water pumps 10 are started synchronously. The operating flow rates of the two water pumps 10 are the same. During the cleaning process, the water pump 10 serving as an input device continuously inputs clean water into the sleeve, and the water pump 10 serving as an output device continuously discharges clean water and discharges it to the filter through a pipe to filter out impurities contained in the water, and then recirculates it into the clean water tank.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The power mechanism includes a forward and reverse motor 17 installed on the top of the connection platform 14, and a first synchronous wheel 18 is fixedly installed on the end of the output shaft of the forward and reverse motor 17; the power mechanism also includes a support frame 15 fixedly installed on the top of the connection platform 14, and the inner wall of the support frame 15 is rotatably connected to a rotating sleeve 16 through a bearing, and the outer periphery of the rotating sleeve 16 is interference-fitted with a second synchronous wheel 19, and the first synchronous wheel 18 and the second synchronous wheel 19 are connected through a synchronous belt 20;

[0037] An inner spiral groove 26 is formed on the inner wall of the rotating sleeve 16, and a disc 27 is sleeved on the inner wall of the rotating sleeve 16. A ball 31 that engages with the inner spiral groove 26 is formed on the outer circumference of the disc 27. A square rod 21 that penetrates to the outside of the rotating sleeve 16 is integrally formed at one end of the disc 27, and the open end of the rotating sleeve 16 does not contact the square rod 21 (that is, the inner wall of the opening of the rotating sleeve 16 is larger than the outer wall of the square rod 21); a fixing plate 13 is fixedly installed on the top of the bottom end plate of the workbench 1 above the connecting platform 14, and a square hole is provided at the center of the fixing plate 13, and the square hole is slidably connected to the outer wall of the square rod 21.

[0038] In this embodiment: after the first sealing plate blocks the inlet and outlet holes of the sleeve, the forward and reverse motor 17 is started, the forward and reverse motor 17 drives the No. 1 synchronous wheel 18 to rotate, the No. 1 synchronous wheel 18 drives the No. 2 synchronous wheel 19 to rotate through the synchronous belt 20, and the No. 2 synchronous wheel 19 drives the rotating sleeve 16 to rotate. When the rotating sleeve 16 rotates, the inner spiral groove 26 therein rotates synchronously. During the rotation process, the inner spiral groove 26 squeezes the ball 31, and the ball 31 moves axially. The ball 31 drives the disc 27 to move axially. At the same time, the square rod 21 and the square hole of the fixed plate 13 slide relative to each other, and the square rod 21 pushes the cleaning mechanism to move synchronously.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3The cleaning mechanism includes a No. 2 sealing plate 23 slidably mounted on the outer wall of one end of the square rod 21, a connecting shaft 24 penetrating to the outside of the fixed plate 13 is formed at one end of the No. 2 sealing plate 23, an anti-slip portion is formed at the end of the connecting shaft 24, a spring 25 is fixedly mounted between the anti-slip portion and the fixed plate 13, a cleaning head 22 is fixedly mounted at one end of the square rod 21 away from the disc 27, and a brush is connected to the outside of the cleaning head 22.

[0040] In this embodiment: when the square rod 21 slides, the square rod 21 pushes the cleaning head 22 to move toward the inner wall of the sleeve. At the same time, the movement of the square rod 21 will cause the No. 2 sealing plate 23 to no longer be limited. At this time, the spring 25 contracts and resets, and the connecting shaft 24 is driven to move by pulling the anti-detachment portion. The moving connecting shaft 24 pushes the No. 2 sealing plate 23 to move until the No. 2 sealing plate 23 contacts the open end of the sleeve. At this time, the No. 2 sealing plate 23 cannot move. At the same time, since the No. 2 sealing plate 23 is provided with a sealing ring, the sealing ring is squeezed and deformed to close the opening of the sleeve. After the No. 2 sealing plate 23 closes the opening of the sleeve, the water inlet function of the water circulation mechanism is started to fill the sleeve with water, and then the synchronous action of water outlet and water inlet is realized.

[0041] At this time, driven by the square rod 21, the cleaning head 22 and the brush outside it reciprocate on the inner wall of the sleeve. It should be noted that after the No. 2 sealing plate 23 is reset to close the sleeve opening, before the cleaning is completed, the cleaning head 22 moves to the maximum distance and must not squeeze the No. 2 sealing plate 23. Here, the forward and reverse angle time of the forward and reverse motor 17 is controlled by the controller.

[0042] Please refer to Figure 1 , Figure 2 and Figure 3 A transducer 28 is installed on the inner wall of the cleaning head 22. The output end of the transducer 28 is connected to a wire 30 that passes through the square rod 21 and the disc 27 and extends to the outside of the rotating sleeve 16. One end of the disc 27 is fixedly connected to a protective tube 29 that passes through the outside of the rotating sleeve 16. The protective tube 29 is used to protect the wire 30 to prevent the wire 30 from getting stuck.

[0043] In this embodiment: after the interior of the sleeve is filled with water, the cleaning head 22 drives the transducer 28 to move back and forth inside the sleeve, and the ultrasonic generator is started. The ultrasonic generator and the transducer 28 convert the sound energy of the power ultrasonic frequency source into mechanical vibration to act on the interior of the cleaning head 22. The mechanical energy acts on the water through the cleaning head 22 to achieve an ultrasonic cleaning effect. At the same time, the reciprocating movement of the brush with the cleaning head 22 can improve the cleaning efficiency of the inner wall of the sleeve. During the movement, the brush brushes the stubborn impurities adhering to the inner wall of the sleeve, and cooperates with ultrasonic cleaning, so that the stubborn impurities can be cleaned faster.

[0044] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
