Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for parts processing, and in particular to a surface oil stain cleaning device for shaft workpiece processing. Background Technology

[0002] During machining, shaft-type workpieces often have a large amount of oil and coolant mixture remaining on their surface due to cutting and cooling processes. This residual oil not only affects the subsequent assembly accuracy and surface treatment quality (such as coating and plating), but also contaminates the production workshop floor, tooling fixtures, and automated equipment during inter-process transfer, increasing equipment maintenance costs and potentially causing safety hazards. Therefore, timely and effective cleaning of oil stains on the surface of shaft-type workpieces is a necessary step to ensure production quality and a clean workshop environment.

[0003] Currently, the industry mainly uses centralized cleaning devices and manual cleaning tools to clean oil stains on the surface of shaft workpieces. Among them, centralized cleaning devices are represented by ultrasonic cleaning machines, which use high-frequency vibration to remove oil stains from the surface of the workpiece. Manual cleaning relies on tools such as rags and brushes, with operators wiping the surface of the workpiece. In addition, some production lines are equipped with simple spray cleaning equipment, which uses high-pressure water jets to rinse the surface of the workpiece to remove oil stains.

[0004] However, existing oil stain cleaning devices have significant shortcomings. Centralized cleaning devices require the workpieces to be transferred to a specific cleaning area for batch processing, which occupies additional transfer time and space and is difficult to adapt to the continuous cycle of automated production lines, resulting in low production efficiency. On the other hand, manual cleaning methods rely on manual operation, which not only results in inconsistent cleaning effects but also cannot be seamlessly integrated with automated equipment such as robotic arms, increasing the cost of manual intervention. To address this deficiency, we propose a surface oil stain cleaning device for shaft workpiece processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface oil stain cleaning device for machining shaft-type workpieces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A surface oil stain cleaning device for machining shaft-type workpieces includes a welded frame, on which an integrally welded shell is fixedly mounted. The shell has a window for observing the internal working conditions. A cover is connected to one side of the shell via a flipping mechanism, which can drive the cover to flip relative to the shell to achieve opening and closing. The housing is equipped with a three-finger pneumatic gripper assembly for clamping shaft-type workpieces. The rotating shaft of the three-finger pneumatic gripper assembly is rotatably connected to the inner wall of the housing through an angular contact ball bearing assembly, and a shaft seal assembly is sleeved on the rotating shaft. The three-finger pneumatic gripper assembly is connected to the external air circuit and electrical circuit through a high-speed pneumatic-electric slip ring. A stepper motor is installed on the outside of the housing. The stepper motor is connected to the rotating shaft of the three-finger gripper assembly through a synchronous belt transmission mechanism, which can drive the three-finger gripper assembly and the workpiece being gripped to rotate at high speed. The housing is also equipped with an air knife assembly for blowing the surface of the workpiece (fixed to the inner wall of the housing). The bottom of the housing is equipped with an oil drain port that communicates with an external oil receiving device. An electrical cabinet is fixed on one side of the welding frame. The electrical cabinet is electrically connected to the flipping mechanism, the stepper motor, the three-finger pneumatic gripper assembly and the high-speed pneumatic-electric slip ring.

[0007] Preferably, the three-finger pneumatic gripper assembly has an adjustable structure, and the opening angle of its gripper can be adjusted by the air pressure.

[0008] Preferably, the flipping mechanism includes a pneumatic push rod or a servo motor, the output end of which is hinged to the cover.

[0009] Preferably, the window is fitted with a transparent acrylic sheet or tempered glass, and the inner side of the sheet is provided with a removable oil-proof film, which is fixed to the edge of the window by magnetic attraction or buckle.

[0010] Preferably, the air knife assembly includes at least two air knife bodies symmetrically distributed on both sides of the workpiece, the air outlet of the air knife body is flat, and the air knife assembly is connected to an external air compressor through a pipeline, and a pressure regulating valve is provided in the pipeline.

[0011] Preferably, the electrical cabinet is equipped with a PLC controller and a touch screen. The touch screen is electrically connected to the PLC controller and can display equipment operating parameters (speed, duration, and gripper pressure) and support manual parameter setting.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention combines high-speed centrifugal oil slinging with auxiliary purging, enabling rapid oil cleaning between processes without the need for additional transport to a specific cleaning area. It effectively adapts to the continuous cycle of automated production lines, reduces the need for manual intervention, and improves overall production smoothness. The sealed operation and centralized collection design prevent oil drips from contaminating the workshop floor, tooling fixtures, and equipment, thereby reducing equipment maintenance costs and safety hazards. Meanwhile, the integrated sealing structure eliminates the risk of oil leakage, ensuring a clean workshop environment; the flexible clamping components and drive system are adaptable to various specifications of shaft workpieces, expanding the equipment's applicability; and the stable transmission and support design ensures safety and durability during high-speed operation, reducing equipment downtime. The overall solution improves cleaning effectiveness while balancing production efficiency, environmental requirements, and equipment stability. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] Reference Figure 1-3A surface oil stain cleaning device for machining shaft-type workpieces includes a welded frame 1, on which an integrally welded shell 2 is fixedly installed. The shell 2 has a window 4 for observing the internal working conditions, with a transparent acrylic plate or tempered glass embedded in the window 4. A removable oil-proof film is provided on the inner side of the window 4, and the oil-proof film is fixed to the edge of the window 4 by magnetic attraction or clips. A cover 3 is connected to one side of the shell 2 via a flipping mechanism 6. The flipping mechanism 6 can drive the cover 3 to flip relative to the shell 2 to achieve opening and closing. The flipping mechanism 6 includes a pneumatic push rod or a servo motor, and the output end of the pneumatic push rod or servo motor is hinged to the cover 3. A three-finger pneumatic gripper assembly 10 for clamping shaft-type workpieces is provided inside the shell 2. The rotating shaft of the three-finger pneumatic gripper assembly 10 is rotatably connected to the inner wall of the shell 2 via an angular contact ball bearing assembly 11, and a shaft seal assembly 13 is fitted on the rotating shaft. The three-finger pneumatic gripper assembly 10 is connected to an external air circuit and electrical circuit via a high-speed pneumatic-electric slip ring 12. The three-finger pneumatic gripper assembly 10 has an adjustable structure. The opening angle of the claw can be adjusted by the air pressure. A stepper motor 7 is installed on the outside of the housing 2. The stepper motor 7 is connected to the rotating shaft of the three-finger pneumatic gripper assembly 10 through a synchronous belt transmission mechanism 8, which can drive the three-finger pneumatic gripper assembly 10 and the workpiece being gripped to rotate at high speed. An air knife assembly for blowing the surface of the workpiece is also provided inside the housing 2 and is fixedly connected to the inner wall of the housing 2. An oil drain port connected to an external oil receiving device is provided at the bottom of the housing 2. An electrical cabinet 5 is fixed on one side of the welded frame 1. The electrical cabinet 5 is electrically connected to the flipping mechanism 6, the stepper motor 7, the three-finger pneumatic gripper assembly 10 and the high-speed pneumatic-electric slip ring 12. The air knife assembly includes at least two air knife bodies symmetrically distributed on both sides of the workpiece. The air outlet of the air knife body is flat. The air knife assembly is connected to an external air compressor through a pipeline. A pressure regulating valve is provided in the pipeline. The electrical cabinet 5 is equipped with a PLC controller and a touch screen. The touch screen is electrically connected to the PLC controller and can display the equipment operating parameters such as speed, duration and gripper pressure, and supports manual parameter setting. During workpiece cleaning, a robotic arm or a person places the shaft-type workpiece into the three-finger pneumatic gripper assembly 10. The pressure of the three-finger pneumatic gripper assembly 10 is regulated by an external air circuit connected to a high-speed pneumatic-electric slip ring 12 to achieve stable clamping of the workpiece. Subsequently, the electrical cabinet 5 controls the flipping mechanism 6 to operate, driving the cover 3 to flip and close relative to the housing 2, thus sealing the cleaning process. Next, the electrical cabinet 5 starts the stepper motor 7, which drives the rotating shaft of the three-finger pneumatic gripper assembly 10 to rotate through the synchronous belt transmission mechanism 8. The rotating shaft rotates stably at high speed under the support of the angular contact ball bearing assembly 11. At the same time, the shaft seal assembly 13 prevents oil from leaking from the gap between the rotating shaft and the housing 2. During this process, the air knife assembly provides high-pressure airflow through a connected external air compressor, which blows the surface of the rotating workpiece through the flat air outlet, accelerating the removal of oil. After cleaning, the stepper motor 7 stops running, the air knife assembly stops blowing, the flipping mechanism 6 starts moving again, the drive cover 3 opens, the three-finger gripper assembly 10 releases the workpiece, and the robot or manual removes the cleaned workpiece. During the cleaning process, the oil sloughed off is thrown to the inner wall of the housing 2 under the action of centrifugal force, and then flows along the inner wall to the oil drain at the bottom of the housing 2, and finally flows into the external oil receiving device for centralized collection. The electrical cabinet 5 coordinates the actions of the flipping mechanism 6, the stepper motor 7, the three-finger gripper assembly 10 and other components throughout the process to ensure that the entire cleaning process is carried out in an orderly manner.

[0017] In summary, this invention combines high-speed centrifugal oil slinging with air knife blowing to quickly clean oil stains from the surface of shaft-type workpieces between processes, eliminating the need for additional transport to a specific area. It effectively adapts to the continuous cycle time of automated production lines, reducing manual intervention and improving production smoothness. The sealed housing and centralized oil drainage design prevent oil drips from contaminating the workshop environment and equipment, reducing maintenance costs and safety hazards. The integrated welded structure eliminates leakage risks, ensuring workshop cleanliness. Furthermore, the adjustable clamping components and stable transmission system adapt to various workpiece specifications, expanding its applicability while ensuring safety and durability during high-speed operation.
