Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to cleaning technology for machined parts. Background Technology

[0002] Mechanical parts processing platforms are key auxiliary equipment after metal cutting, grinding, drilling and other processes. They are mainly used for temporary placement, positioning and surface debris removal of workpieces.

[0003] Traditional machining platforms typically consist of a fixed table, simple enclosure, and manual cleaning tools (such as brushes and air guns). Their core function is to provide temporary support for the machined workpiece and to manually remove residual metal shavings, coolant residue, and other impurities from the surface to prevent scratches or impact on subsequent assembly accuracy. In mass production scenarios, the platform's stability and cleaning efficiency directly affect the overall machining cycle time and product yield.

[0004] The existing technology has the following shortcomings: 1. Cleaning up dead corners and inefficiency.

[0005] Traditional machining platforms rely on manual handheld air guns or brushes for cleaning, which makes it difficult to completely remove debris from workpiece grooves, blind holes, complex curved surfaces, etc., leaving 20%-30% of cleaning dead zones; the average daily workpiece volume cleaned by a single person is only about 50% of that of automated equipment.

[0006] The design of machining platforms has long followed the traditional paradigm of "fixed table + manual operation." Technological improvements have mostly been limited to upgrading table materials (such as anti-static and wear-resistant materials), failing to break through the "tool active - workpiece passive" technical route. Existing technologies focus on the "external tool - static workpiece" cleaning mode, without considering exposing hidden areas through workpiece movement (such as rotation or flipping), resulting in airflow or brushes being unable to cover all surfaces. In contrast, this patent application establishes a technical route that uses workpiece rotation and airflow in synergy to clean dead corners.

[0007] 2. Debris splashing and environmental pollution.

[0008] During the cleaning process, debris blown away by the high-pressure airflow from the open platform can easily splash into the workshop environment, leading to dust accumulation on the equipment and an increased risk of inhalation by operators, requiring an additional 30% of the workshop cleaning cost.

[0009] Traditional platform designs prioritize ease of operation, neglecting "enclosed cleaning" as a core requirement. With increasing environmental regulations, the conflict between open structures and the "clean production" concept is becoming increasingly apparent. Existing technologies focus on "open space - unconstrained airflow" operations, lacking a closed structure synchronized with workpiece cleaning, leading to uncontrollable debris diffusion paths. In contrast, this patent application establishes a technical approach that creates a dynamically enclosed space through a lifting bucket and a top plate.

[0010] 3. Positioning deviation and secondary damage.

[0011] Manual cleaning requires frequent movement of the workpiece to adjust the angle, which can easily cause the positioning reference of the workpiece on the platform to shift, with a cumulative positioning error of 0.1-0.3mm, which may lead to excessive machining accuracy in subsequent processes; improper control of manual clamping force can also cause indentations on the workpiece surface.

[0012] Traditional platforms are limited to "carrying loads" and are not deeply integrated with the "precision continuity" requirements of processing procedures, resulting in a lag in the application of automated positioning technology in low-cost platforms. Existing technologies focus on calibration methods based on "manual visual inspection and positioning," without integrating automated clamping and rotation positioning mechanisms, leading to the inability to lock the workpiece's posture during dynamic cleaning. In contrast, this patent application establishes a technical approach that achieves precise reset after rotation through electromagnet-spring linkage.

[0013] 4. High cost of manual intervention.

[0014] Dedicated personnel are required to handle workpiece loading and unloading, cleaning operations, and positioning calibration. Labor costs account for more than 60% of the platform's total operating costs. Furthermore, the consistency of manual operations is poor, and the cleaning quality is significantly affected by experience.

[0015] The machining industry has long prioritized processing equipment over auxiliary equipment, resulting in low priority for automation upgrades of auxiliary platforms and lagging technological iteration behind the main processing unit. Existing technologies focus on a workflow of "dispersed processes followed by manual intervention," failing to achieve an automated closed loop of "clamping-cleaning-positioning," with each step requiring independent manual intervention. In contrast, this patent application establishes a technical route for achieving streamlined operations through motor drive and sensor feedback.

[0016] In summary, traditional mechanical parts processing platforms have significant shortcomings in terms of cleaning efficiency, environmental adaptability, positioning accuracy, and automation, and can no longer meet the precision manufacturing industry's production demands for "high efficiency, cleanliness, and precision." Therefore, developing an easy-to-clean processing platform that integrates dynamic enclosed space, workpiece self-rotation cleaning, and automatic positioning and resetting functions has become an inevitable trend to overcome existing technological bottlenecks. The "easy-to-clean mechanical parts processing platform" proposed in this patent application is a systematic solution to the aforementioned problems. Utility Model Content

[0017] The purpose of this utility model is to provide an easy-to-clean mechanical parts processing platform that can form a closed cleaning space through the relative movement of the fixed placement plate and the lifting bucket, so as to overcome the defects of the prior art caused by the lack of a closed structure in the cleaning process, resulting in debris overflow or unstable workpiece positioning.

[0018] To achieve the above objectives, the easy-to-clean mechanical parts processing platform of this utility model includes a base support, an L-shaped support plate fixedly installed on the top of the base support, a connecting plate fixedly connected to the L-shaped support plate at one end, a bearing plate fixedly installed at the other end of the connecting plate, and a lifting closed bucket that is movably connected to the base support (1) in the vertical direction and surrounds the outside of the bearing plate; a top plate is provided above the lifting closed bucket, and the top plate is used to form a relatively closed workpiece cleaning space with the lifting closed bucket after it is raised; The inner wall of the lifting enclosed bucket is provided with a clearance opening for the connecting plate to pass through, and a sealing baffle is fixedly installed on the top of the connecting plate to block the clearance opening.

[0019] The lower part of the lifting enclosed hopper has a cone-shaped guide structure that is smaller at the bottom and larger at the top, and a debris discharge port is provided at the center of the bottom end of the cone-shaped guide structure.

[0020] The upper surface of the bearing plate is provided with workpiece mounting seats at both ends on the same side of the upper surface of the bearing plate; A U-shaped plate is fixedly connected to the upper surface of the base support seat on the outer side of the lifting closed bucket. The opening of the U-shaped plate is downward and connected to the base support seat (1). A limit guide rod is fixedly connected to the top of the U-shaped plate. A lifting plate is slidably connected to the limit guide rod. One side of the lifting plate is installed on the limit guide rod in a sliding fit through its guide hole. The other side of the lifting plate is threadedly engaged with a vertically extending threaded rod through its threaded hole. A lifting motor is installed at the top of the U-shaped plate. The output shaft of the lifting motor is driven downward and connected to the threaded rod. The lifting plate is fixedly connected to the side wall of the lifting closed bucket. The lifting motor is used to drive the lifting closed bucket to lift.

[0021] The vertical height of the clearance opening is greater than the maximum lifting stroke of the lifting enclosure, and the vertical height of the enclosure baffle matches the vertical height of the clearance opening.

[0022] The connecting plate has a triangular cross-section, and its two ends along its length are fixedly connected to the top of the L-shaped support plate and the side edge of the bearing plate, respectively.

[0023] It also includes a workpiece rotation cleaning system mounted on the support plate, the workpiece rotation cleaning system including a rotary motor, a rotating shaft, a transmission assembly, a rotating rod and a workpiece clamping assembly; The rotary motor is fixed to the bottom of the support plate by a support plate, and its output end is connected to the rotating shaft for transmission. The transmission assembly includes a driving wheel, a transmission belt, and a driven wheel mounted on a rotating shaft. The workpiece mounting base has a cavity. The rotating rod passes through the workpiece mounting base and is rotatably slidably engaged with it. The driven wheel is slidably connected to the external spline on the rotating rod via an internal spline to achieve torque transmission. The driven wheel is mounted on the rotating rod within the cavity. The transmission belt is wound between the driving wheel and the driven wheel. The workpiece clamping assembly includes a clamping plate connected to the inner end of the rotating rod. The outer end of the rotating rod is connected to an electric telescopic rod via a thrust bearing. The electric telescopic rod is connected to the workpiece mounting base via a fixed structure. Two sets of transmission components are symmetrically arranged. The two sets of transmission components are located at the two ends of the rotating shaft and the bearing plate, respectively. The clamping plates of the two sets of transmission components are used to clamp the workpiece in the center.

[0024] It also includes a positioning system that works in conjunction with the workpiece rotation cleaning system, the positioning system comprising a turntable, a positioning groove, an elastic reset mechanism and a pressure sensor; The turntable is fixedly sleeved on the end of the rotating shaft away from the rotating motor. The outer wall is uniformly provided with positioning grooves, and pressure sensors are embedded in the grooves. The elastic reset mechanism includes a fixed plate, an electromagnet, a spring, a storage plate, a movable seat, and rollers. The fixed plate is fixed to the outer wall of the support plate. The electromagnet, the spring, and the iron storage plate are fixed downwards on one side of the bottom of the fixed plate in sequence. The bottom of the storage plate is rotatably connected to the rollers through the movable seat. The rollers are in rolling contact with the outer wall of the turntable. The pressure sensor is wirelessly connected to an electronic control device, which is connected to the electromagnet, lifting motor, and rotary motor.

[0025] It also includes a debris removal system installed on the top plate, the debris removal system including a fan, a connecting pipe, a fixed pipe and multiple nozzles; the fan is fixed to the top of the L-shaped frame and located above the top plate, the L-shaped frame is fixedly connected to the top plate; the air outlet is connected to the fixed pipe through the connecting pipe; the multiple nozzles are installed on the fixed pipe, and the outlet of each nozzle faces the workpiece clamping area between the clamps of the two sets of transmission components.

[0026] This utility model has the following advantages: The bearing plate 13 is rigidly fixed to the base support 1 by the L-shaped support plate 10 and the connecting plate 11, forming a rigid support chain, namely the rigid support chain between the base support 1, the L-shaped support plate 10, the triangular connecting plate 11, and the bearing plate 13. This ensures that the bearing plate 13 and the base support 1 are relatively stationary, solving the problem of unstable positioning caused by the lifting bucket. When the lifting closed bucket 2 is lifted, it avoids the opening 9 from sliding relative to the connecting plate 11. The closed baffle 12 always covers the opening area, and together with the enclosure effect of the lifting closed bucket, it forms a closed cleaning space, effectively blocking the debris overflow path and overcoming the defect of "open cleaning leading to debris diffusion" in the prior art.

[0027] The conical guide structure 90 guides debris (such as iron and aluminum shavings) during the cleaning process to the bottom and gathers it by means of the inclined inner wall. The smooth inner wall reduces the adhesion of debris, avoids debris residue in the hopper and improves cleaning efficiency. Compared with the straight wall structure, it reduces the dead corners of debris accumulation, reduces the area of ​​the discharge port, realizes centralized discharge and reduces the frequency of manual cleaning.

[0028] The collected debris is discharged directly to an external collection device (such as a waste bin) through the debris discharge port 91, realizing the automation of the "cleaning-collection" process. No manual dumping is required, which solves the efficiency problem of manual cleaning of debris in traditional processing platforms.

[0029] The lifting motor 4 drives the lifting plate 6 and the lifting enclosed bucket 2 to lift together via the threaded rod 5. During this process, the limit guide rod 7 plays a role in limiting and guiding the lifting plate 6, ensuring that the lifting enclosed bucket 2 lifts and lowers smoothly.

[0030] The specific provisions for avoiding opening 9 and closing baffle 12 ensure that the lifting and closing bucket 2 does not interfere with the connecting plate 11 throughout its entire stroke. At the same time, the closing baffle 12 always covers the critical area of ​​opening 9, preventing debris from overflowing from the opening gaps and improving the reliability of the closure.

[0031] The two ends of the triangular connecting plate 11 are rigidly connected to form a stable triangular support structure, which improves the load-bearing capacity and vibration resistance of the bearing plate 13 and ensures processing accuracy.

[0032] The workpiece rotation cleaning system has a simple structure and can reliably clamp the workpiece and rotate it smoothly. Through rigid power transmission of "motor-shaft-belt drive", the workpiece can rotate 360°. When combined with the chip blowing system, it can basically eliminate the dead corners of the workpiece surface cleaning.

[0033] The mechanical-electromagnetic coordinated positioning of "electromagnet-spring-roller-positioning groove" enables automatic reset of the workpiece after rotation, solving the problem of low efficiency of manual calibration; the pressure sensor 26 provides a signal to the electronic control device to trigger the rotating motor to stop in time, so that the workpiece stops in a horizontal state, which is convenient for subsequent removal.

[0034] Through the airflow transmission design of "fan-pipeline-array nozzle", an airflow field covering the surface of the workpiece is formed. Combined with the rotation of the workpiece, it can achieve cleaning without dead angles and improve the debris removal effect. The airflow blowing and the closed space formed by the lifting closed bucket 2 work together to confine the debris splashing within the lifting closed bucket 2 and improve the workshop environment.

[0039] Figure 5 This is a three-dimensional structural diagram of the debris removal system. Detailed Implementation

[0040] like Figures 1 to 5 As shown, the easy-to-clean mechanical parts processing platform of this utility model includes a base support 1, an L-shaped support plate 10 fixedly installed on the top of the base support 1, a connecting plate 11 fixedly connected to the L-shaped support plate 10 at one end, a bearing plate 13 fixedly installed at the other end of the connecting plate 11, and a lifting enclosed bucket 2 that is movably connected to the base support 1 in the vertical direction and surrounds the outside of the bearing plate 13; a top plate 38 is provided above the lifting enclosed bucket 2, and the top plate 38 is used to form a relatively enclosed workpiece cleaning space with the lifting enclosed bucket 2 after it is raised; The inner wall of the lifting enclosed bucket 2 is provided with a clearance opening 9 for the connecting plate 11 to pass through, and a sealing baffle 12 for blocking the clearance opening 9 is fixedly installed on the top of the connecting plate 11.

[0041] The base support 1, L-shaped support plate 10, connecting plate 11, bearing plate 13 and lifting enclosed bucket 2 can be made of engineering plastic, cast iron or aluminum alloy, and the enclosed baffle 12 can be made of steel plate.

[0042] The bearing plate 13 is rigidly fixed to the base support 1 by the L-shaped support plate 10 and the connecting plate 11, forming a rigid support chain, namely the rigid support chain between the base support 1, the L-shaped support plate 10, the triangular connecting plate 11, and the bearing plate 13. This ensures that the bearing plate 13 and the base support 1 are relatively stationary, solving the problem of unstable positioning caused by the lifting bucket. When the lifting closed bucket 2 is lifted, it avoids the opening 9 from sliding relative to the connecting plate 11. The closed baffle 12 always covers the opening area, and together with the enclosure effect of the lifting closed bucket, it forms a closed cleaning space, effectively blocking the debris overflow path and overcoming the defect of "open cleaning leading to debris diffusion" in the prior art.

[0043] The fixed design of the load-bearing plate achieves mechanical stability through "rigid series connection of multiple components", and the enclosed structure achieves spatial enclosure through a combination of "dynamic avoidance + static shielding". The two work together to solve the core contradiction between "positioning stability" and "debris spill prevention".

[0044] The lower part of the lifting enclosed hopper 2 has a cone-shaped guide structure 90 that is smaller at the bottom and larger at the top, and a debris discharge port 91 is provided at the center of the bottom end of the cone-shaped guide structure 90.

[0045] The generatrix of the conical guide structure 90 forms an angle of 30°~60° (preferably 45°) with the vertical direction, and its inner wall surface is anodized or chrome-plated (surface roughness Ra≤1.6μm). The large end diameter of the conical guide structure 90 is consistent with the upper diameter of the lifting closed hopper. The "aggregation effect" of the conical structure works synergistically with the "discharge channel" of the material discharge port to form a complete "guiding-aggregation-discharge" cleaning process, improving the continuity of the overall processing platform.

[0046] The conical guide structure 90 guides debris (such as iron and aluminum shavings) during the cleaning process to the bottom and gathers it by means of the inclined inner wall. The smooth inner wall reduces the adhesion of debris, avoids debris residue in the hopper and improves cleaning efficiency. Compared with the straight wall structure, it reduces the dead corners of debris accumulation, reduces the area of ​​the discharge port, realizes centralized discharge and reduces the frequency of manual cleaning.

[0047] The debris discharge port 91 can be equipped with a removable sealing cover (the sealing cover is a conventional technology, not shown in the figure, used to close the discharge port when not being cleaned).

[0048] The collected debris is discharged directly to an external collection device (such as a waste bin) through the debris discharge port 91, realizing the automation of the "cleaning-collection" process. No manual dumping is required, which solves the efficiency problem of manual cleaning of debris in traditional processing platforms.

[0049] The upper surface of the support plate 13 is provided with two workpiece mounting seats 14 at the two ends of the same side; the two workpiece mounting seats 14 are symmetrically distributed in the edge area of ​​the support plate 13. The workpiece mounting seats 14 serve as the support structure for the rotary cleaning structure.

[0050] A U-shaped plate 3 is fixedly connected to the upper surface of the base support 1 on the outer side of the lifting enclosed bucket 2. The opening of the U-shaped plate 3 faces downward and is connected to the base support 1. A limit guide rod 7 is fixedly connected to the top of the U-shaped plate 3. A lifting plate 6 is slidably connected to the limit guide rod 7. One side of the lifting plate 6 is installed on the limit guide rod 7 through its guide hole in a sliding fit. The other side of the lifting plate 6 is threadedly engaged with a vertically extending threaded rod 5 through its threaded hole. A lifting motor 4 is installed at the top of the U-shaped plate. The output shaft of the lifting motor 4 is driven downward to the threaded rod 5. The lifting plate 6 is fixedly connected to the side wall of the lifting enclosed bucket 2. The lifting motor 4 is used to drive the lifting enclosed bucket 2 to lift.

[0051] The lifting motor 4 is a forward and reverse stepper motor. Forward rotation causes the lifting enclosed bucket 2 to rise or fall, while reverse rotation causes the lifting enclosed bucket 2 to fall or rise.

[0052] The lifting motor 4 drives the lifting plate 6 and the lifting enclosed bucket 2 to lift together via the threaded rod 5. During this process, the limit guide rod 7 plays a role in limiting and guiding the lifting plate 6, ensuring that the lifting enclosed bucket 2 lifts and lowers smoothly.

[0053] The vertical height of the clearance opening 9 is greater than the maximum lifting stroke of the lifting enclosed bucket 2, and the vertical height of the enclosed baffle 12 matches the vertical height of the clearance opening 9.

[0054] The specific provisions for avoiding opening 9 and closing baffle 12 ensure that the lifting and closing bucket 2 does not interfere with the connecting plate 11 throughout its entire stroke. At the same time, the closing baffle 12 always covers the critical area of ​​opening 9, preventing debris from overflowing from the opening gaps and improving the reliability of the closure.

[0055] By using "opening overtravel design + baffle height adaptation", static shading is achieved during dynamic processes, ensuring the continuity of the sealing effect.

[0056] The connecting plate 11 has a triangular cross-section, and the two ends of the connecting plate 11 along its length are fixedly connected to the top of the L-shaped support plate 10 and the side edge of the bearing plate 13, respectively.

[0057] The two ends of the triangular connecting plate 11 are rigidly connected to form a stable triangular support structure, which improves the load-bearing capacity and vibration resistance of the bearing plate 13 and ensures processing accuracy.

[0058] It also includes a workpiece rotation cleaning system installed on the support plate 13, the workpiece rotation cleaning system including a rotary motor 16, a rotating shaft 17, a transmission assembly, a rotating rod 19 and a workpiece clamping assembly; The rotary motor 16 is fixed to the bottom of the bearing plate 13 by the support plate 15, and its output end is connected to the rotating shaft 17 for transmission. The transmission assembly includes a drive wheel 18, a transmission belt 21, and a driven wheel 20 mounted on the rotating shaft 17. The workpiece mounting base 14 has a cavity. The rotating rod 19 passes through the workpiece mounting base 14 and is rotatably and slidably engaged with it. The driven wheel 20 is slidably connected to the external spline on the rotating rod 19 via an internal spline to achieve torque transmission. The driven wheel 20 is mounted on the rotating rod 19 within the cavity. The transmission belt 21 is wound between the drive wheel 18 and the driven wheel 20. The workpiece clamping assembly includes a clamping plate 23 connected to the inner end of the rotating rod 19. The outer end of the rotating rod 19 is connected to an electric telescopic rod 22 via a thrust bearing. The electric telescopic rod 22 is an electric push rod, which transmits thrust but not torque between the electric telescopic rod 22 and the rotating rod 19. The electric telescopic rod is connected to the workpiece mounting base 14 via a fixed structure. The fixed structure is a common connecting frame, not shown in the figure.

[0059] Two sets of transmission components are symmetrically provided. The two sets of transmission components are located at the two ends of the rotating shaft 17 and the bearing plate 13, respectively. The clamping plates 23 of the two sets of transmission components are used to clamp the workpiece (mechanical part) in the middle.

[0060] The workpiece rotation cleaning system has a simple structure and can reliably clamp the workpiece and rotate it smoothly. Through rigid power transmission of "motor-shaft-belt drive", the workpiece can rotate 360°. When combined with the chip blowing system, it can basically eliminate the dead corners of the workpiece surface cleaning.

[0061] The support plate 15 and the bearing plate 13 are fixedly connected by bolts (M8×30), with a verticality error of ≤0.1mm / m, to ensure that the rotating shaft 17 is perpendicular to the surface of the bearing plate 13 and to avoid rotational eccentricity.

[0062] It also includes a positioning system that works in conjunction with the workpiece rotation cleaning system, the positioning system including a turntable 24, a positioning groove 25, an elastic reset mechanism and a pressure sensor 26; The turntable 24 is fixedly sleeved on the end of the rotating shaft 17 away from the rotating motor 16. The outer wall is uniformly provided with positioning grooves 25, and pressure sensors 26 are embedded in the grooves. The elastic reset mechanism includes a fixed plate 27, an electromagnet 28, a spring 29, a storage plate 30, a movable seat 31, and a roller 32. The fixed plate 27 is fixed to the outer wall of the support plate 15. The electromagnet 28, the spring 29, and the iron storage plate 30 are fixed downwards on one side of the bottom of the fixed plate 27 in sequence. The bottom of the storage plate is rotatably connected to the roller 32 through the movable seat 31. The roller makes rolling contact with the outer wall of the turntable 24. A limit plate 33 is slidably inserted on the other side of the bottom of the fixed plate 27. The limit plate 33 is used to prevent the storage plate 30 from tilting. The pressure sensor is connected to an electronic control device via wireless (or wired) communication. The electronic control device is connected to the electromagnet 28, the lifting motor 4, and the rotary motor 16. The electronic control device is a microcontroller or an integrated circuit.

[0063] The mechanical-electromagnetic coordinated positioning of "electromagnet-spring-roller-positioning groove" enables automatic reset of the workpiece after rotation, solving the problem of low efficiency of manual calibration; the pressure sensor 26 provides a signal to the electronic control device to trigger the rotating motor to stop in time, so that the workpiece stops in a horizontal state, which is convenient for subsequent removal.

[0064] During cleaning, the electromagnet 28 is energized to attract the iron storage plate 30, the spring 29 is compressed, the roller 32 disengages from the positioning groove 25, and the workpiece begins to rotate. After cleaning, the electromagnet 28 is de-energized, the spring 29 returns to its original position and pushes the moving seat 31. The roller 32 rolls along the outer wall of the turntable 24 into the positioning groove 25, triggering the pressure sensor 26. The rotary motor 16 stops, and the workpiece is reset to the horizontal processing position (before the rotary motor 16 starts, the roller 32 is already in the positioning groove 25, which corresponds to the horizontal state of the workpiece).

[0065] It also includes a debris removal system installed on the top plate 38, the debris removal system including a fan 34, a connecting pipe 35, a fixed pipe 36 and multiple nozzles 37; the fan 34 is fixed to the top of the L-shaped frame 8 and located above the top plate 38, the L-shaped frame 8 is fixedly connected to the top plate 38; the air outlet is connected to the fixed pipe 36 through the connecting pipe 35; the multiple nozzles 37 are installed on the fixed pipe 36, and the outlet of each nozzle 37 faces the workpiece clamping area between the clamping plates 23 of the two sets of transmission components.

[0066] The airflow transmission design of "fan-pipeline-array nozzles" creates an airflow field covering the workpiece surface, which, combined with the workpiece's rotation, achieves thorough cleaning without dead angles, improving the debris removal effect. The airflow jets and the enclosed space formed by the lifting and enclosed hopper 2 work together to confine debris splashes within the lifting and enclosed hopper 2, improving the workshop environment. The nozzles 37 are detachable and replaceable (adapting to different outlet diameters) to meet the cleaning needs of workpieces made of different materials (such as aluminum parts and cast iron parts).

[0067] The working process of this utility model is as follows: 1. Workpiece clamping and initial positioning.

[0068] Workpiece placement: Manual or robotic arm places the mechanical parts to be cleaned (such as gears and shafts) between the two clamping plates 23; the electrical control device (not shown) controls the extension of the electric telescopic rod 22, and pushes the clamping plates 23 to clamp the workpiece in the center through the rotating rod 19 (the clamping force is set according to the material of the workpiece, such as 50-100N for aluminum parts and 150-200N for cast iron parts).

[0069] Function of rigid support chain: The bearing plate 13 is rigidly fixed to the base support 1 through the rigid support chain, so there is basically no vibration or displacement during processing or cleaning, which solves the positioning deviation problem caused by the movement of the workpiece with the lifting bucket in traditional platforms.

[0070] 2. The formation of enclosed clean spaces.

[0071] The lifting enclosed bucket rises: The lifting motor 4 is started and rotates forward, driving the threaded rod 5 to rotate. The lifting plate 6 rises vertically along the limit guide rod 7, causing the lifting enclosed bucket 2 to rise and form a relatively enclosed workpiece cleaning space with the top plate 38. During the rising process, the opening 9 slides relative to the triangular connecting plate 11, and the closing baffle 12 always covers the opening area, working together with the lifting enclosed bucket 2 to form a closed cleaning space and block the path of debris overflow.

[0072] 3. Workpiece rotation and debris blowing work together for cleaning.

[0073] Rotation system startup: The electric control device triggers the electromagnet 28 to be energized, adsorbing the iron storage plate 30, compressing the spring 29, and disengaging the roller 32 from the positioning groove 25; the rotary motor 16 starts, driving the driven wheel 20 and the rotating rod 19 to rotate through the rotating shaft 17, the driving wheel 18, and the transmission belt 21, causing the workpiece to rotate 360°.

[0074] The debris removal system works as follows: when the blower 34 starts, it generates a high-pressure airflow, which is sprayed out from the nozzle 37 through the connecting pipe 35 and the fixed pipe 36, forming an airflow field covering the surface of the workpiece. During the rotation of the workpiece, all areas of the workpiece surface are in contact with the airflow. With the help of the conical guide structure 90 and the inclined inner wall, the debris slides down the wall and accumulates at the bottom, avoiding the existence of cleaning dead corners in the lifting closed bucket 2.

[0075] 4. Positioning and resetting, and debris removal.

[0076] Rotation and positioning stop: After cleaning is completed (reaching the set cleaning time, such as 10-30 seconds), the electric control device controls the electromagnet 28 to be de-energized, the spring 29 to reset and push the moving seat 31, the roller 32 to roll along the outer wall of the turntable 24 into the positioning groove 25, triggering the pressure sensor 26, the electric control device immediately stops the rotating motor 16, and the workpiece is reset to the initial horizontal position for easy removal later.

[0077] Debris collection and discharge: By opening the sealing cover of the debris discharge port 91, the accumulated debris is discharged into an external collection device (such as a waste bin) under the action of gravity. The "cleaning-collection" process is very convenient. The sealing cover can be replaced by a solenoid valve, which is controlled by an electronic control device, facilitating automated operation.

[0078] 5. Retrieve parts and reset the system.

[0079] Lifting and closing bucket descends: Lifting motor 4 reverses, driving lifting and closing bucket 2 to descend to the initial position, opening the closed space; electric telescopic rod 22 retracts, clamping plate 23 releases the workpiece, and manual or robotic arm removes the cleaned workpiece.

[0080] System standby: The fan 34 is turned off, the sealing cover closes the material discharge port 91, and the platform enters the next work cycle to adapt to the continuous cleaning of workpieces.

[0081] Synergy between stable positioning and debris spill prevention during operation: The rigid support chain ensures that the workpiece is fixed in position during cleaning, while the dynamic closed structure blocks debris spillage through the combination of "avoidance opening 9 + closed baffle 12". The two work together to solve the contradiction between "positioning accuracy" and "environmental cleanliness".

[0082] High efficiency of rotary cleaning and conical guide: The combination of workpiece rotation (360° no dead angle) and multi-angle airflow (covering a diameter of 300mm), along with the 90° gathering effect of the conical guide structure, improves the debris removal effect, significantly improving cleaning efficiency and cleaning effect compared to traditional manual cleaning.

[0083] Balancing automation and low cost: The simple control logic of "electric telescopic rod 22 + electromagnet 28 + pressure sensor 26" is used to replace the complex servo system, so as to realize the assembly line operation of "clamping-cleaning-positioning-chip removal" at a lower cost.
