DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0035] Example:

[0036] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] Please refer to Figure 1-4 As shown, the present application provides an automatic cleaning device for hydraulic cylinder processing for engineering machinery, including a frame 1, a cleaning part 2, a cleaning slide 3, a limit fixing component 4, a rotating drive part 5, a sliding base 6 and a protective box 8.

[0038] Reference Figure 1 As shown, the protective box 8 is located outside the frame 11 and the cleaning part 2, and the protective box 8 is fixedly connected to the frame 1. A feed port 81 is provided in the front of the protective box 8, and the feed port 81 is used for the cleaning slide 3 and the workpiece 7 to enter the protective box 8. The cleaning part 2 is fixedly connected to the frame 1, and the cleaning part 2 has a cleaning end, and the cleaning end is used to clean the workpiece 7. In the present embodiment, the cleaning part 2 adopts a high-pressure water gun 21, and the cleaning end is the nozzle of the high-pressure water gun 21. In addition, in the present embodiment, the high-pressure water gun 21 is connected to a robot arm 22, and the robot arm 22 has the degrees of freedom of the X-axis and the Y-axis on the horizontal plane. The robot arm 22 is fixedly connected to the top of the protective box 8, and the robot arm 22 is electrically connected to the controller 23, and the robot arm 22 can be driven to move horizontally by inputting instructions to the controller 23.

[0039] Please refer to Figure 1-4 As shown, a frame plate 11 is installed on the frame 1, and mounting grooves 12 are provided on the left and right sides of the frame plate 11 along the width direction, and the cleaning slide plate 3 is slidably connected in the mounting groove 12. A plurality of rotating rollers 13 are arranged in the mounting groove 12, and the rotating rollers 13 are rotatably connected to the frame plate 11, and the plurality of rotating rollers 13 are evenly arranged along the width extension direction of the frame plate 11. A force is provided to the cleaning slide plate 3, which can drive the cleaning slide plate 3 to slide in the mounting groove 12. Due to the rotating rollers 13, the friction between the cleaning slide plate 3 and the mounting groove 12 is further reduced. A clamping device for easy clamping and fixing is provided on the cleaning slide plate 3, and the clamping device is used to clamp and fix the hydraulic cylinder 42. The clamping device is a prior art and will not be described in detail here.

[0040] In addition, since the cleaning slide plate 3 can slide into the protective box 8, on the one hand, it is avoided that the operator repeatedly moves the cleaning slide plate 3, which causes a waste of manpower. On the other hand, since the cleaning part 2 uses a high-pressure water gun 21, the sliding can reduce the probability of the high-pressure water flow sprayed by the high-pressure water gun 21 injuring the operator.

[0041] Please refer to Figure 1 -as shown, the workbench is arranged close to the protective box 8, and a plurality of conveying rollers for the cleaning slide 3 to slide are evenly arranged inside the workbench. The sliding base 6 is slidably arranged on the conveying rollers, and a multi-directional sliding member 61 is arranged above the sliding base 6. The cleaning slide 3 can be slidably connected to the multi-directional sliding member 61, and the multi-directional sliding member 61 is used to drive the cleaning slide 3 to slide along the length or width direction parallel to the frame plate 11. The multi-directional sliding member 61 includes a plurality of balls, and the balls are evenly rotated and arranged on the sliding base 6. By arranging the multi-directional sliding member 61, the sliding of the cleaning slide 3 is facilitated. In actual sliding, the cleaning slide 3 is driven to slide by pushing the sliding base 6. When the sliding base 6 is close to the frame plate 11, the cleaning slide 3 can enter the mounting groove 12 and slide by sliding inertia.

[0042] The limiting and fixing assembly 4 is arranged on the frame plate 11, and when the cleaning slide plate 3 slides into the mounting groove 12, the limiting and fixing assembly 4 can fix the cleaning slide plate 3. The four corners of the cleaning slide plate 3 are provided with fixing grooves 31. The limiting and fixing assembly 4 includes a plurality of fixing blocks 41, a plurality of cylinders 42, a first limiting block 43 and a second limiting block 44. The shape of each fixing block 41 is the same as the shape of the fixing groove 31. The plurality of cylinders 42 have output shafts, and the output shafts of the cylinders 42 can move in a straight line direction, and the driving cylinders 42 can drive the fixing blocks 41 fixedly connected to the output shafts of the cylinders 42 to be inserted into the fixing grooves 31. In this embodiment, the cylinders 42 are used to drive the fixing blocks 41 to approach and be inserted into the fixing grooves 31 or to move away from the fixing grooves 31.

[0043] Please refer to Figure 1-4 As shown, the first limiting block 43 is provided with a limiting groove 431, which is installed on the inner side of the frame plate 11 near the midpoint. The limiting groove 431 is parallel to the cleaning slide 3, and the cleaning slide 3 can be inserted into the limiting groove 431. When the cleaning slide 3 is driven to slide in the installation groove 12 and abuts against and inserts into the limiting groove 431, the fixing block 41 is aligned with the fixing groove 31. The first limiting block 43 and the limiting groove 431 are designed to prevent the cleaning slide 3 from slipping, and at the same time, the fixing block 41 can be aligned with the fixing groove 31 for subsequent fixing.

[0044] The second limit block 44 is installed on the side of the frame plate 11, and is arranged close to the first limit block 43. An anti-collision cotton pad or other materials with a buffering function are installed on the side of the second limit block 44 close to the cleaning slide 3. In this embodiment, the buffer material is an anti-collision cotton pad. When the cleaning slide 3 is fully inserted into the limit groove 431, the second limit block 44 abuts against the cleaning slide 3. The second limit slide is used to perform secondary limit on the cleaning slide 3 to prevent one end of the cleaning slide 3 from being offset. At the same time, the anti-collision cotton pad can buffer the impact of the cleaning slide 3 on the first limit block 43 and the second limit block 44.

[0045] The rotary drive member 5 is fixedly connected to the frame 1, and the rotary drive member 5 has a rotating end, which is fixedly connected to the frame plate 11, and the rotary drive member 5 is used to drive the frame plate 11 to rotate. In this embodiment, the rotary drive member 5 is a servo motor, and the rotating shaft of the servo motor is fixedly connected to the frame plate 11. When the servo motor is turned on, the rotating shaft can rotate, and the rotation of the rotating shaft can drive the frame plate 11 to rotate. The rotation of the frame plate 11 drives the fixed cleaning slide 3 to rotate, and then drives the workpiece 7 on the cleaning slide 3 to rotate. The workpiece 7 rotates, thereby realizing the rapid and thorough cleaning of the multi-angle holes and grooves of the hydraulic cylinder workpiece 7, and effectively removing the metal chips in the holes and grooves.

[0046] The implementation principle of the embodiment of the present application is:

[0047] First, place and fix the hydraulic cylinder workpiece 7 to be cleaned on the cleaning slide 3, and then push the cleaning slide 3 to slide into the protective box 8. During the sliding process of the cleaning slide 3, the first limit block 43 and the second limit block 44 play a limiting role to prevent the slide from slipping, and the anti-collision cotton pad provides a buffer to protect the cleaning slide 3 and the limit block from impact damage. The multi-directional sliding member 61 (ball) on the sliding base 6 allows the cleaning slide 3 to slide along the length or width direction of the frame plate 11 during the cleaning process, which is convenient for quickly adjusting the position of the cleaning slide 3. The cylinder 42 in the limit fixing assembly 4 drives the fixing block 41 to be inserted into the fixing groove 31 of the cleaning slide 3 to ensure that the cleaning slide 3 is firmly positioned in the frame plate 11. Then start the cleaning end of the high-pressure water gun 21 to spray high-pressure water to clean the surface of the hydraulic cylinder and remove surface dirt. At the same time, the rotary drive member 5 (servo motor) is started to drive the frame plate 11 and the cleaning slide plate 3 and the workpiece 7 thereon to rotate, ensuring that the high-pressure water gun 21 can clean the hydraulic cylinder from different angles, especially the metal chips inside the hole groove can also be thoroughly cleaned. The present application achieves efficient cleaning of the hydraulic cylinder hole groove and completely removes metal chips through the cooperation of the high-pressure water gun 21 and the rotary drive member 5. The design of the protective box 8 and the sliding structure reduces the direct contact of the operator and improves the safety of operation. The limit fixing assembly 4 and the multi-directional sliding member 61 ensure the automation of the cleaning process, reduce labor costs, and improve cleaning efficiency. In addition, the present device can adapt to hydraulic cylinders of different sizes and shapes and has good applicability.

[0048] It should be noted that the high-pressure water gun 21, the robotic arm 22 and the controller 23 in this embodiment are all devices purchased on the market, and the models can be selected or customized according to actual needs. In this application, we only use them and do not improve their structure and function. For the technicians in this field, their setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of their instruction manual, and they will not be described in detail here.

[0049] 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.
