Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a cleaning device for mechanical parts processing. Background Technology

[0002] When repairing automotive sheet metal, the paint on the scratched or scraped areas needs to be sanded and scraped off. After the sheet metal is reshaped, the surface of the sheet metal is cleaned to remove impurities generated during the repair process, ensuring the repaired area is clean and thus facilitating subsequent painting.

[0003] Currently, the main cleaning method is rinsing, followed by wiping the water droplets off the steel plate surface. This method can affect the subsequent anti-rust coating process because water droplets may remain. If the moisture is not completely dried, it may cause blisters or blistering in the repaired area, affecting the repair effect and the vehicle's appearance. Furthermore, the entire rinsing and drying process relies heavily on manual labor, requiring frequent relocation, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cleaning device for machining mechanical parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cleaning device for machining mechanical parts includes a base. A mounting platform that moves back and forth along the base's length is connected to the base via a ball screw mechanism. A mounting box is mounted on the mounting platform. A swing arm is rotatably connected to the center of the mounting box. In a preferred embodiment, a fixed shaft is provided in the middle of the swing arm, and the swing arm is rotatably connected to the inner wall of the mounting box via this fixed shaft. Connecting rods are rotatably mounted at both ends of the swing arm. Two longitudinally arranged guide cylinders are provided on the top of the mounting box. An air cylinder and a liquid cylinder are slidably inserted into the guide cylinders, respectively. A pneumatic nozzle is provided at the top of the air cylinder, and a hydraulic nozzle is provided at the top of the liquid cylinder. The bottoms of the air cylinder and the liquid cylinder are rotatably connected to the movable ends of the two connecting rods, and the pneumatic nozzle and the hydraulic nozzle face the same direction.

[0006] In a preferred embodiment, the ball screw mechanism includes a ball screw, a screw nut, and a servo motor. The two ends of the ball screw are rotatably mounted on the inner side of the base. The screw nut is threaded onto the ball screw. The servo motor is located at one end of the base, and the transmission shaft at the output end of the servo motor is connected to the ball screw via a coupling.

[0007] In a preferred embodiment, the top of the lead screw nut is connected to the mounting platform, and a straight groove is formed on the upper surface of the base to allow the mounting platform to move back and forth in a straight line.

[0008] In a preferred embodiment, a disc is provided inside the mounting box, and a push rod is rotatably connected to an eccentric position on the disc surface. The other end of the push rod is rotatably connected to one end of the swing rod, and a rotary motor for controlling the rotation of the disc is provided outside the mounting box.

[0009] In a preferred embodiment, an air pump and a liquid pump are respectively provided on both sides of the mounting box. The output end of the air pump is connected to an air cylinder through an air pipe, and the liquid pump is connected to a liquid cylinder through a liquid pipe.

[0010] The beneficial effects of this utility model are: The cleaning device proposed in this solution solves the problem that residual water droplets after cleaning the sheet metal surface of mechanical parts are difficult to remove, which affects the subsequent repair effect and aesthetics. The proposed cleaning device can thoroughly clean the surface of the steel plate through the horizontally moving hydraulic nozzle, and can quickly dry the residual water droplets on the surface of the steel plate with the help of the air pressure nozzle, preventing water stains and ensuring the subsequent restoration of the sheet surface. Moreover, the entire cleaning process is automatic, simple and efficient. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] In this embodiment, refer to Figure 1-3A cleaning device for machining mechanical parts includes a base 1. A mounting platform 2, which moves back and forth along its length, is connected to the base 1 via a ball screw mechanism 3. The ball screw mechanism 3 includes a ball screw, a screw nut, and a servo motor. Both ends of the ball screw are rotatably mounted inside the base 1. The screw nut is threaded onto the ball screw. The servo motor is located at one end of the base 1, and its output shaft is connected to the ball screw via a coupling. The top of the screw nut is connected to the mounting platform 2. A straight groove is formed on the upper surface of the base 1 to allow the mounting platform 2 to move back and forth linearly. The servo motor drives and controls the horizontal movement of the mounting platform 2.

[0015] Regarding the internal structure of the mounting box 4, in conjunction with the attached... Figure 1 and appendix Figure 3 As can be seen, a mounting box 4 is provided on the mounting platform 2, and a swing rod 7 is rotatably connected to the center of the interior of the mounting box 4. Regarding this swing rod 7, it should be noted that, as shown in the attached... Figure 3 As shown, the middle part of the swing arm 7 is provided with a fixed shaft, and the swing arm 7 is rotatably connected to the inner wall of the mounting box 4 through the fixed shaft.

[0016] Connecting rods 8 are rotatably mounted at both ends of the swing arm 7. The two connecting rods 8 are staggered to prevent positional interference during transmission. Two longitudinally arranged guide cylinders 9 are installed on the top of the mounting box 4. An air cylinder 10 and a liquid cylinder 12 are slidably inserted into the guide cylinders 9, respectively. An air nozzle 13 is installed at the top of the air cylinder 10, and a hydraulic nozzle 11 is installed at the top of the liquid cylinder 12. The bottoms of the air cylinder 10 and the liquid cylinder 12 are rotatably connected to the movable ends of the two connecting rods 8. An air pump 14 and a liquid pump 15 are respectively installed on both sides of the mounting box 4. The output end of the air pump 14 is connected to the air cylinder 10 via an air pipe, and the liquid pump 15 is connected to the liquid cylinder 12 via a liquid pipe.

[0017] The cleaning water is delivered to the liquid cylinder 12 by the liquid pump 15 and then pressurized and sprayed outward through the hydraulic nozzle 11 to clean the surface of the mechanical parts. The gas is delivered to the air cylinder 10 by the air pump 14 and then pressurized and sprayed outward through the air pressure nozzle 13 to dry the surface of the cleaned parts and prevent residual water droplets from forming water stains and affecting the appearance.

[0018] For the replacement of pneumatic nozzle 13 and hydraulic nozzle 11, refer to the attached document. Figure 1The mounting box 4 contains a disc 5, with a push rod 6 rotatably connected to an eccentric position on the disc surface. The other end of the push rod 6 is rotatably connected to one end of a swing rod 7. A rotary motor controlling the rotation of the disc 5 is located outside the mounting box 4. The rotary motor controls the rotation of the disc 5. During the rotation of the disc 5, the push rod 6 periodically pushes or pulls the swing rod 7, causing the swing rod 7 to swing back and forth around its central fulcrum. During this back-and-forth swinging motion, the connecting rods 8 on both sides respectively push the liquid cylinder 12 or the air cylinder 10 to a higher position.

[0019] When the liquid cylinder 12 is raised, the air cylinder 10 is lowered; conversely, when the air cylinder 10 is raised, the liquid cylinder 12 is lowered. At any given time, only one nozzle can be raised to a higher position and act on the surface of the component. Finally, it should be noted that the pneumatic nozzle 13 and the hydraulic nozzle 11 are oriented in the same direction.

[0020] Once the surface of the component is aligned with the two nozzles, the operator first controls the rotation of the disc 5, causing the push rod 6 to push the swing arm 7 to raise the hydraulic nozzle 11. The hydraulic nozzle 11 is then used to quickly clean the surface of the component. The ball screw mechanism controls the hydraulic nozzle 11 to move back and forth in the horizontal direction to thoroughly clean the component. After cleaning, the disc 5 continues to rotate, and the push rod 6 pulls the swing arm 7 to raise the pneumatic nozzle 13. The pneumatic nozzle 13 is then used to quickly dry the surface of the component to prevent water stains from remaining. This process, combined with the ball screw mechanism 3, thoroughly dries the surface of the component. The entire process is automated, simple, and efficient.

[0021] The pneumatic nozzle 13 and the hydraulic nozzle 11 are arranged side by side in the longitudinal direction. Once the position of the component is determined, the position of the hydraulic nozzle 11 can be set in front, that is, the hydraulic nozzle 11 is closer to the component. In this way, the droplets sprayed by the hydraulic nozzle 11 can quickly complete the cleaning purpose, which is simple and practical.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
