Description

Technical Field

[0001] This invention relates to the field of mechanical structure processing equipment technology, and in particular to an energy-saving precision mechanical structure cleaning device. Background Technology

[0002] Machinery refers to all machines and mechanisms. Machinery is a tool or device that helps people reduce the difficulty of work or save effort. Precision machinery refers to machinery with high dimensional accuracy. Precision machinery is mostly produced using high-precision CNC lathes or CNC machining centers. It needs to ensure various accuracy requirements such as external dimensions, internal dimensions, and surface roughness. Precision machinery is widely used in production equipment, transportation vehicles, aerospace, and even military facilities.

[0003] In existing technologies, after precision machinery is manufactured, it requires cutting fluid for lubrication and cooling during the production process, resulting in the presence of cutting fluid and metal powder residue on its surface. Furthermore, during the storage and transportation of precision machinery, grease needs to be applied for rust prevention. Before further finishing or packaging, precision machinery needs to be cleaned to remove the stains on its surface. To address these issues, we propose an energy-saving precision machinery structure cleaning device. Summary of the Invention

Vertically arranged partitions are also fixedly connected to the inner wall of the cleaning tank. The cleaning tank also includes a rinsing assembly, and a discharge mechanism is installed on the inner wall of the cleaning tank away from the conveying assembly.

[0007] The rinsing assembly includes a water pump located inside the cleaning tank. One end of the water pump is connected to an inlet pipe, which is fixedly connected to a float via a traction rope. The float is slidably connected to the inner wall of the cleaning tank. The water pump is also connected to an outlet pipe, which is perpendicular to the mesh conveyor belt. Multiple spray nozzles are provided on the side wall of the outlet pipe near the mesh conveyor belt. A shaft is rotatably connected inside the cleaning tank and abuts against the mesh conveyor belt. A drive gear is fixedly connected to the side wall of the shaft. A rotating rod is rotatably connected inside the cleaning tank, and a driven gear meshing with the drive gear is fixedly connected to the side wall of the rotating rod. The outlet pipe is located inside the rotating rod, and a felt roller is sleeved on the rotating rod. An arc-shaped plate is fixedly connected to the inner wall of the cleaning tank near the felt roller.

[0008] Preferably, the feeding mechanism includes a support frame, an arc-shaped frame is fixedly connected to the upper end of the support frame, and a drive motor is fixedly connected to the arc-shaped frame. A rope shaft is fixedly connected to the output end of the drive motor, and a pull rope is wound on the rope shaft. A rectangular slider is fixedly connected to the end of the pull rope away from the rope shaft, and the rectangular slider is slidably connected to the support frame and the arc-shaped frame. A grid plate is rotatably connected to the upper part of the rectangular slider, and a circular slider is rotatably connected to the grid plate and slidably connected to the support frame. A connecting rod is fixedly connected to the lower end of the support frame, and a receiving plate assembly is fixedly connected to the connecting rod.

[0009] Preferably, the receiving plate assembly includes a plate body, which is disposed near the mesh conveyor belt, and a vertically arranged baffle is fixedly connected to the upper surface of the plate body. A clearance groove is also formed on the upper surface of the plate body, and a strip groove is formed on the upper surface of the plate body near the inner wall of the cleaning tank. A sliding sleeve is also fixedly connected to the upper surface of the plate body, and a compression spring is fixedly connected inside the sliding sleeve. A wedge block is fixedly connected to the end of the compression spring away from the sliding sleeve.

[0010] Preferably, the grid plate is provided with a frame around its perimeter, and a counterweight is provided inside the frame.

[0011] Preferably, a guide plate is fixedly connected to one side of the cleaning tank, and the guide plate is positioned away from the support frame.

[0012] Preferably, an inclined guide plate is fixedly connected inside the cleaning tank, and an inclined ash receiving plate is fixedly connected inside the cleaning tank, with one end of the ash receiving plate away from the inner wall of the cleaning tank located inside the mesh conveyor belt.

[0013] Preferably, a lever is fixedly connected to the lower surface of the guide plate, and the lever is arranged to abut against the mesh conveyor belt.

[0014] Preferably, the end of the mesh conveyor belt near the unloading component is connected through a partition, and the upper end of the partition is higher than the horizontal position of the washing tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, by setting up a cleaning tank in conjunction with an ultrasonic transducer, uses the most efficient and convenient ultrasonic cleaning method to clean precision mechanical structures. The mesh conveyor belt can drive the mechanical structure to move in the cleaning tank, and the rinsing mechanism can clean the residual impurities on the mechanical structure. By setting a partition in the cleaning tank, the cleaning tank is divided into two areas, so that the user puts the mechanical structure into the cleaning tank from one side of the partition and takes it out from the other side of the partition. This can prevent the oil stains floating on the water surface from being re-adsorbed onto the mechanical structure when it is taken out.

[0017] In addition, the rinsing components installed in the cleaning tank directly drive the water flow within the tank, which can separate the metal powder from the mechanical structure. After separation, the metal powder passes through the mesh conveyor belt and settles at the bottom of the cleaning tank, ultimately ensuring that the precision mechanical structure is completely cleaned by the cleaning device.

[0018] 2. In this invention, by setting up a water inlet pipe that is fixed to the float with a traction rope, the position of the water inlet pipe can avoid both the metal powder at the bottom of the cleaning tank and the grease floating on the surface of the cleaning water. This minimizes the intake of impurities by the water inlet pipe, making the water used to rinse the mechanical structure clearer and preventing secondary pollution when the rinsing components rinse the mechanical structure.

[0019] 3. The present invention, by setting up a feeding mechanism composed of a support frame and an arc-shaped structure, can rotate the grid plate after it is moved to the upper end of the support frame by using a drive electric motor, thereby unloading the mechanical structure on the grid plate after it has been cleaned, thus improving the automation level of the cleaning device and making it more convenient to use.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figure 1-7 An energy-saving precision mechanical structure cleaning device includes a cleaning tank 1; a mesh conveyor belt 2 is installed inside the cleaning tank 1, and multiple ultrasonic transducers 3 are installed on the inner wall of the cleaning tank 1, with the ultrasonic transducers 3 located on both sides of the mesh conveyor belt 2; vertically arranged partitions 4 are also fixedly connected to the inner wall of the cleaning tank 1; a rinsing assembly is also provided in the cleaning tank 1; and a feeding mechanism is also provided on the inner wall of the cleaning tank 1 away from the conveying assembly.

[0030] The rinsing assembly includes a water pump 5 located within the cleaning tank 1. One end of the water pump 5 is connected to a water inlet pipe 6, which is fixedly connected to a float 7 via a traction rope. The float 7 is slidably connected to the inner wall of the cleaning tank 1. The water pump 5 is also connected to an outlet pipe 8, which is perpendicular to the mesh conveyor belt 2. Multiple spray nozzles are provided on the side wall of the outlet pipe 8 near the mesh conveyor belt 2. A shaft 9 is rotatably connected within the cleaning tank 1. 9 is set against the mesh conveyor belt 2. A drive gear 10 is fixedly connected to the side wall of the shaft 9. A rotating rod 11 is rotatably connected inside the cleaning tank 1. The rotating rod 11 is a hollow grid-shaped round rod. A driven gear 12 that meshes with the drive gear 10 is fixedly connected to the side wall of the rotating rod 11. The water outlet pipe 8 is set inside the rotating rod 11. A felt roller 13 is also sleeved on the rotating rod 11. An arc plate 29 is fixedly connected to the inner wall of the cleaning tank 1 near the felt roller 13.

[0031] In this embodiment, the cleaning tank 1 is a metal water tank with a drain pipe at its bottom or near the bottom side wall. The ultrasonic transducer 3 is a commonly used device in the field of ultrasonic cleaning. Its application in this invention is to improve the cleaning effect and reduce the use of cleaning agents. While reducing cleaning costs, it is also more environmentally friendly. The partition 4 is used to divide the cleaning water into sections. After the cleaning water submerges the mechanical structure, the oil stains on the mechanical structure will float on the water surface. By using the partition 4 to separate the water surface, when the mechanical structure is taken out, it can be avoided that the mechanical structure is contaminated with grease. In this way, there is no need to add surfactants to the cleaning water to dissolve the oil stains.

[0032] In the cleaning assembly, the water pump 5 drives the water flow in the cleaning tank 1, directly drawing in water from the cleaning tank 1 and spraying it out from the nozzle to rinse the mechanical structure. Since the ultrasonic cleaning equipment is used, the water pressure requirement for the rinsing assembly is low. It is only used to rinse away solid impurities that have been shaken off by the ultrasonic waves but have not detached from the mechanical structure due to its shape. The shaft 9 set in the cleaning tank 1, together with the drive gear 10 and the driven gear 12, drives the felt roller 13 to rotate. This is used to place the mechanical structure on the mesh conveyor belt 2, which may cause the bottom layer of mechanical structure to be unable to be rinsed clean. In this type of cleaning device, it is used to clean mechanical structures with more complex shapes. It uses a combination of ultrasonic waves and rinsing, and does not require the use of cleaning agents to assist in cleaning, which reduces cleaning costs and is more environmentally friendly. It should be noted that some rusted mechanical structures need to be soaked in rust remover first and then the cleaning device is used to remove the rust remover and the rust stains adhering to the metal.

[0033] Furthermore, the feeding mechanism includes a support frame 14, with an arc-shaped frame 15 fixedly connected to the upper end of the support frame 14. A drive motor 16 is fixedly connected to the arc-shaped frame 15, and a rope shaft 17 is fixedly connected to the output end of the drive motor 16. A pull rope 18 is wound around the rope shaft 17, and a rectangular slider 19 is fixedly connected to the end of the pull rope 18 away from the rope shaft 17. The rectangular slider 19 is slidably connected to the support frame 14 and the arc-shaped frame 15. A grid plate 20 is rotatably connected to the upper part of the rectangular slider 19, and a circular slider 21 is rotatably connected to the grid plate 20 and slidably connected to the support frame 14. The lower end of the support frame 14 is fixedly connected to... There is a connecting rod 22, and a receiving plate assembly 23 is fixedly connected to the connecting rod 22. In this type of unloading assembly, the lower half of the support frame 14 is immersed in the cleaning water. The H-shape of the support frame 14 allows the mechanical structure to be cleaned and then transported to the receiving plate assembly 23 by the network conveyor belt when the user is cleaning the mechanical structure. Then, the drive motor 16 and the pull rope 18 drive the grid plate 20 to take the mechanical structure out of the water. After the rectangular slider 19 moves along the arc frame 15, it drives the grid plate 20 to rotate, thereby tilting the mechanical structure of the grid plate 20 down, realizing automated cyclic operation and further improving the automation level of this cleaning device.

[0034] Furthermore, the receiving plate assembly 23 includes a plate body 231, which is positioned near the mesh conveyor belt 2. A vertically arranged baffle 232 is fixedly connected to the upper surface of the plate body 231. A clearance groove is also formed on the upper surface of the plate body 231, and a strip groove is formed on the upper surface of the plate body 231 near the inner wall of the cleaning tank 1. A sliding sleeve 233 is also fixedly connected to the upper surface of the plate body 231. A compression spring 234 is fixedly connected inside the sliding sleeve 233, and a wedge block 235 is fixedly connected to the end of the compression spring 234 away from the sliding sleeve 233. The receiving plate assembly 23 is used in conjunction with the grid plate 20. The baffle 232 prevents downward-falling metal components from detaching from the plate body 231, while the strip groove provides clearance for the grid plate 20. When the grid plate 20 moves upward, it can carry all the parts on the receiving plate assembly 23 upward. The sliding sleeve 233 is set to assist the grid plate 20 in resetting. Since the mechanical structure has accumulated on the receiving plate assembly 23 when the grid plate 20 moves downward to return to the initial position, after the grid plate 20 moves to the position of the sliding sleeve 233, the sliding sleeve 233 drives the grid plate 20 to rotate to a vertical state, so that the grid plate 20 can continue to move downward until the grid plate 20 disengages from the sliding sleeve 233. Then the grid plate 20 rotates to a horizontal state. When the grid plate 20 moves upward, it drives the wedge block 235 to move to make way for the grid plate 20. Finally, the grid plate 20 moves upward while maintaining a horizontal state, removing the mechanical structure accumulated on the receiving plate assembly 23 from the water.

[0035] Furthermore, the grid plate 20 is provided with a frame 24 around its perimeter, and a counterweight is provided inside the frame 24. This design is used to ensure the physical strength of the grid plate 20, and also to ensure that the grid plate 20 can return to its initial position under its own weight.

[0036] Furthermore, a guide plate 25 is fixedly connected to one side of the cleaning tank 1, and the guide plate 25 is set away from the support frame 14. The guide plate 25 is set to guide the mechanical structure put into the cleaning tank 1 onto the mesh conveyor belt 2.

[0037] Preferably, an inclined guide plate 26 is fixedly connected inside the cleaning tank 1, and an inclined dust receiving plate 27 is fixedly connected inside the cleaning tank 1. The end of the dust receiving plate 27 away from the inner wall of the cleaning tank 1 is located inside the mesh conveyor belt 2. Most of the metal powder and sediment impurities located on the mechanical structure will fall onto the mesh conveyor belt 2, while the guide plate 26 is used to receive and collect the metal powder, which facilitates the subsequent cleaning of the cleaning tank 1.

[0038] Furthermore, a lever 28 is fixedly connected to the lower surface of the guide plate 26, and the lever 28 is set against the mesh conveyor belt 2. When the mesh conveyor belt 2 is running, the lever 28 can drive the guide plate 26 to vibrate. At this time, the metal powder on the guide plate 26 will fall onto the dust receiving plate 27 along the guide plate.

[0039] Furthermore, the mesh conveyor belt 2 is installed through the partition plate 4 at one end near the feeding component, and the upper end of the partition plate 4 is higher than the horizontal position of the cleaning tank 1. In the actual cleaning process, due to the need to feed materials and add cleaning water, the water in the cleaning tank 1 will vibrate. Setting the partition plate 4 higher can prevent oil stains from crossing the partition plate 4.

[0040] In this invention, after activating the mesh conveyor belt 2 and ultrasonic transducer 3 within the cleaning device, the user inserts the mechanical structure to be cleaned from the end of the cleaning tank 1 furthest from the unloading assembly. Smaller parts can be added in bulk. Once inside the cleaning tank 1, the mechanical structure slides along the guide plate 25 onto the mesh conveyor belt 2 and moves towards the unloading assembly under its influence. After the mechanical structure is submerged in water, most of the oil residue detaches and floats on the surface. During this movement, the ultrasonic waves generated by the ultrasonic transducer 3, combined with the cleaning water, clean the mechanical structure, removing any remaining oil. Impurities, metal powder, and residual oil stains detach from the mechanical structure. However, due to the often complex shape of the mechanical structure, other impurities and metal powder that cannot float on the water surface remain attached to it. As the mesh conveyor belt 2 operates, it also drives the shaft 9 to rotate. The shaft 9 should drive the gear 10 to rotate the rotating rod 11. At this time, the felt roller 13 also rotates, but the rotation direction of the felt roller 13 is opposite to the direction of the conveyor belt. When the stacked mechanical structure moves to the position of the felt roller 13, the rotation direction of the felt roller 13 is opposite to the rotation direction of the mesh conveyor belt 2, and the shaft 9 obstructs the movement of the mechanical structure, thus... As the mechanical structure moves upward, the felt roller 13, in conjunction with the arc-shaped plate 29, clamps the mechanical structure and moves it along the lower surface of the arc-shaped plate 29. Although the dirt inside the mechanical structure has been separated from it by the ultrasonic vibration, it may still remain inside, especially in more complex shapes. At this point, water sprayed from the outlet of the water pipe 8 passes through the felt roller 13 to rinse the mechanical structure, and the felt yarn on the roller 13 penetrates deep into the interior of the mechanical structure. As the water sprays into the interior of the mechanical structure, it also causes the yarn to swing, and when the yarn detaches from the mechanical structure, it carries away the dirt inside. When dealing with complex mechanical structures with irregular shapes such as narrow slits and blind holes, it can effectively improve the cleaning effect, reduce stain residue, and penetrate deep into the mechanical structure. On the other hand, by setting up floats 7 in conjunction with pull ropes 18, the position of the water inlet pipe 6 can be suspended in the water, which can avoid sucking in oil stains and floating objects on the water surface, as well as metal powder settled at the bottom of the cleaning tank 1. While avoiding secondary pollution, it also protects the water pump 5 and prevents the spray nozzle from clogging. After the mechanical structure is rinsed, the mesh conveyor belt 2 transports the mechanical structure to the unloading component, and then the unloading component removes the mechanical structure, thus completing the entire cleaning operation.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
