Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and in particular to a fully automatic vortex polishing machine. Background Technology

[0002] Traditional finishing machines mostly employ vibratory, drum, or centrifugal grinding. The separation of abrasive from the workpiece often requires machine shutdown, manual sieving, or the use of external screening equipment. This process is cumbersome and generates dust and noise, resulting in low levels of automation. Especially for small, precision workpieces, achieving efficient, closed-loop automatic loading and unloading and abrasive circulation is difficult, leading to low processing efficiency, a poor working environment, and significant abrasive loss. Therefore, the market needs a highly automated finishing solution that integrates automatic filling, intelligent separation, and abrasive recovery.

[0003] Patent CN215700742U discloses a vortex polishing machine, including a frame and a polishing barrel. A cycloidal pinwheel motor is connected to the bottom of the polishing barrel. The polishing barrel includes a grinding upper plate and a rotating base. A connecting cover is fitted onto the outer side of the rotating base, and a motor guard is located below the connecting cover. A connecting ring is formed at the outer edge of the bottom of the grinding upper plate, with multiple circumferentially arranged lugs formed on it. A connecting flange is formed at the bottom of the connecting cover, which is fixed to the top of the motor guard by multiple circumferentially arranged hexagonal bolts. Both the inner surfaces of the grinding upper plate and the rotating base are coated with a polyurethane layer, and the polyurethane layer on the inner surface of the grinding upper plate has radiating rib-like protrusions. This patent uses a cycloidal pinwheel motor, which allows for variable frequency speed control, reducing noise. The connecting structure has uniform stress and small gaps. The polyurethane lining provides good wear resistance and reduces equipment wear. Furthermore, the radiating rib-like protrusions inside the grinding upper plate prevent thin, sheet-like, or filamentous parts from adhering to the inner wall of the grinding upper plate, ensuring a good polishing effect.

[0004] The existing technology has the following drawbacks:

[0005] The inability to quickly separate abrasive and workpiece is a significant drawback. Existing equipment lacks an integrated and efficient automatic separation mechanism, typically relying on simple gravity settling for initial separation. This results in incomplete separation of abrasive and workpiece, which is time-consuming and labor-intensive. Each separation process requires machine shutdown, relying on manual screening or external equipment. Furthermore, abrasive residue often remains after separation, severely impacting production efficiency and significantly increasing labor costs and intensity. In addition, the open-style manual separation operation causes dust and noise pollution in the working environment, and residual abrasive directly affects the processing quality of the next batch of workpieces, making it difficult to guarantee the consistency of batch processing quality.

[0006] The existing equipment is designed with limited functionality and lacks integrated storage bins, automatic feeding mechanisms, and closed-loop return pipeline systems. Therefore, it cannot complete the storage, quantitative filling, and automatic recycling of abrasives within the machine. The entire process is highly dependent on manual labor, from weighing and pouring during feeding to manually transferring the mixture to the screening equipment after grinding. The process is cumbersome and frequently interrupted. This results in a low overall automation rate, and the overall production efficiency is limited by the speed and rhythm of manual operation. At the same time, open operation can easily lead to abrasive waste and environmental pollution, making it difficult to achieve a continuous, clean, and efficient production model. Summary of the Invention

[0007] Given the problems of existing technologies, such as the inability to quickly separate abrasive and workpiece and the inability to automatically fill and recycle abrasive, a fully automatic vortex finishing machine is proposed.

[0008] This application provides a fully automatic vortex finishing machine, the purpose of which is to: achieve rapid and thorough automatic separation of abrasive and workpiece after grinding by setting an automatic separation structure, without stopping the processing flow; at the same time, by setting an automatic filling and recycling structure, achieve automatic feeding of abrasive and recycling, transportation and reuse of grinding abrasive; significantly improve production efficiency, reduce labor costs and labor intensity, ensure the consistency of batch processing quality, and realize a continuous, clean and closed production mode.

[0009] The technical solution of the present invention is as follows: a fully automatic vortex polishing machine, including a machine table, a second telescopic cylinder fixedly installed inside the machine table and a plurality of first telescopic cylinders, a servo motor fixedly installed at the output end of the second telescopic cylinder, and a storage cylinder fixedly connected to the top of the machine table, and a grinding mechanism disposed inside the storage cylinder.

[0010] The grinding mechanism includes a grinding cylinder and a rotating shaft. The grinding cylinder is located inside the storage cylinder. The bottom of the rotating shaft is fixedly connected to the output shaft of the servo motor. A vortex disk is fixedly connected to the top of the rotating shaft. The outer wall of the vortex disk is slidably connected to the inner wall of the grinding cylinder.

[0011] The grinding mechanism also includes a material distribution cylinder disposed at the bottom of the grinding cylinder. Multiple material blocking rings are fixedly connected to the top of the material distribution cylinder. Multiple annular grooves are formed on the inner wall of the vortex disk. The inner walls of the multiple annular grooves are slidably connected to the outer walls of the corresponding material blocking rings. A material distribution cavity is formed on the inner wall of the material distribution cylinder. Multiple mating interfaces are formed on the outer wall of the material distribution cavity.

[0012] By adopting the above scheme, a highly automated grinding and separation process is achieved through telescopic drive and split nested structure. The second telescopic cylinder is linked with the first telescopic cylinder to control the lifting and lowering of the vortex disk and grinding cylinder, completing the docking with the material storage system. Inside the equipment, the precise nesting and separation structure of the vortex disk, material distribution cylinder and material blocking ring, combined with the elastic support system of support ring and telescopic spring, achieves precise opening and closing control of the separation gap. This results in the fully automated completion of quantitative abrasive filling, efficient vortex grinding of workpieces, and automatic separation and recycling of abrasive and workpieces without intervention.

[0013] Furthermore, the inner wall of the grinding cylinder is fixedly connected with multiple sliding rods, and both ends of the sliding rods are fixedly connected with limit seats. The outer wall of the vortex disk is provided with multiple recesses, and the sliding rods are slidably engaged in the corresponding recesses. The vortex disk and the grinding cylinder are fixedly connected in the circumferential direction to transmit torque, and can slide relative to each other in the axial direction.

[0014] Furthermore, the inner wall of the dispensing cylinder is provided with multiple sliding slots, and the outer wall of the rotating shaft is fixedly connected with multiple sliding plates. The outer wall of the sliding plate is slidably connected to the inner wall of the corresponding sliding slot, and the dispensing cylinder rotates synchronously with the vortex disk through the sliding slots and sliding plates.

[0015] By adopting the above scheme, the precise linkage and power transmission of key moving parts are achieved through the sliding engagement of the slide rod and the notch, as well as the transmission pair of the sliding plate and the sliding groove. The notch engagement between the slide rod and the vortex disk allows them to be fixed in the circumferential direction to transmit torque, while allowing relative sliding in the axial direction. This ensures that the grinding cylinder can be reliably driven by the vortex disk to complete the lifting and lowering motion. The engagement of the sliding plate and the sliding groove allows the rotating shaft to both drive the distribution cylinder to rotate synchronously and achieve axial sliding. A composite transmission system integrating rotation drive, axial lifting and lowering, and motion decoupling is constructed, ensuring that the actions in each stage, such as grinding, separation, and material return, can be executed accurately, coordinatedly, and reliably, realizing a fully automated operation process.

[0016] Furthermore, the inner wall of the grinding cylinder is provided with multiple grooves, and a free-rotating shaft is fixedly connected to the inner wall of the grooves. An opening and closing lifting plate and a gravity block are fixedly connected to the outer wall of the free-rotating shaft. The opening and closing lifting plate is located inside the grinding cylinder, and the gravity block is located outside the grinding cylinder. The outer wall of the grinding cylinder is provided with multiple limiting grooves.

[0017] Using the above scheme, a dynamic opening and closing lifting plate system is formed by grooves, free rotating shafts, opening and closing lifting plates, gravity blocks, and limiting grooves. When rotating at high speed, centrifugal force causes the opening and closing lifting plates to expand outward around the axis, forcibly lifting and throwing materials to form a highly efficient three-dimensional vortex. When stopped or at low speed, the gravitational torque of the gravity block drives the lifting plates to automatically retract and fully embed into the groove, thereby achieving efficient mixing in the grinding stage and interference-free automatic reset in the separation stage.

[0018] Furthermore, the inner wall of the storage cylinder is provided with multiple lifting grooves, and lifting sliders are slidably connected to the inner wall of the lifting grooves. Bearings are fixedly connected between the multiple lifting sliders, and the inner wall of the bearings is fixedly connected to the outer wall of the grinding cylinder.

[0019] The above solution uses a lifting guide and rotation bearing system consisting of a lifting slide, a lifting slider, and bearings. This system enables stable and precise lifting of the grinding cylinder in the vertical direction. At the same time, the bearings allow for extremely low frictional resistance when the grinding cylinder rotates at high speeds, ensuring the independent, stable, and smooth execution of the two core actions of lifting and rotation, thus supporting the dynamic requirements of the entire workflow.

[0020] Furthermore, a fixing ring is fixedly connected to the inner wall of the storage cylinder, a support ring is slidably connected to the inner wall of the storage cylinder, a telescopic spring is fixedly connected between the support ring and the fixing ring, the top of the support ring is rotatably connected to the bottom of the distributing cylinder, and the rotating shaft passes through the center of the support ring.

[0021] The above scheme forms an axial elastic support system consisting of a fixed ring, a support ring, and a telescopic spring. When the vortex disk is pressed down, the spring is compressed and stores energy. When the pressure is released, the spring releases its elastic force, pushing the support ring and the distribution cylinder to reset. This ensures that the lifting and lowering movement of the grinding cylinder is precise and stable, and always maintains the necessary support stiffness and dynamic reset capability.

[0022] Furthermore, the inner wall of the storage cylinder is provided with a storage cavity, and a pusher block is slidably connected to the inner wall of the storage cavity. The bottom of the pusher block is fixedly connected to the output end of the first telescopic cylinder.

[0023] Furthermore, the inner wall of the storage chamber is provided with multiple discharge ports and multiple return ports, and the multiple return ports are respectively connected to multiple docking ports.

[0024] Furthermore, a sealing cap is fixedly installed on the top of the storage cylinder.

[0025] The above scheme constitutes a closed-loop automatic abrasive supply and recovery system consisting of a storage chamber, a pusher block, a first telescopic cylinder, a discharge port, a return port, and a sealing cover. It realizes the automatic and quantitative filling and recovery of abrasive in a closed environment. The pusher block pushes up to complete the filling and moves down to receive the returned abrasive. The sealing cover ensures the airtightness of the operation process, effectively reduces noise and dust emission, and ensures operational safety and cleanliness.

[0026] The beneficial effects of this invention are:

[0027] By setting up a precision separation mechanism consisting of a distribution cylinder, a blocking ring, a vortex disk, and an annular groove, and combining it with the lifting drive of the second telescopic cylinder, the problems of incomplete separation and the need for manual operation during machine shutdown in existing technologies are effectively solved. During the separation stage, the lifting system lifts the grinding cylinder, so that the blocking ring of the distribution cylinder and the annular groove of the vortex disk are precisely aligned and separated, forming a gap. Centrifugal force throws the lighter abrasive into the distribution chamber through this gap, and then into the storage chamber for recycling through the interface and return port. The workpiece is blocked by the blocking ring and remains in the grinding cylinder. This improves production efficiency, ensures the consistency of the processing environment and quality of each batch of workpieces, and avoids dust and noise pollution caused by open separation.

[0028] By integrating a storage cylinder, storage chamber, pusher block, first telescopic cylinder, discharge port, and sealing cover, a complete automatic abrasive supply and recycling system is constructed. This fundamentally solves the problems of low automation, process interruption, abrasive waste, and environmental pollution caused by reliance on manual feeding and transfer. During the working cycle, the first telescopic cylinder drives the pusher block to move upward, quantitatively pushing the pre-stored abrasive in the storage chamber into the grinding cylinder through the discharge port, completing automatic filling. After grinding and separation, the abrasive is automatically returned to the bottom of the storage chamber for temporary storage through the separation mechanism and return port. This reduces labor costs and labor intensity, and achieves closed-loop management and near-zero waste recycling of abrasive, supporting the stable operation of continuous, clean, and high-efficiency production modes.

[0029] By designing an axial sliding circumferential transmission pair between the slide rod and the notch, a synchronous rotating pair between the sliding plate and the sliding slot, a dynamic opening and closing system between the opening and closing lifting plate and the gravity block, and a guiding rotation system between the lifting slider and the bearing, a highly coordinated composite motion actuator is formed. The slide rod and the notch ensure that the grinding cylinder can be driven to rotate by the vortex disk and can also independently complete the lifting and lowering. The sliding plate and the slot enable the dispensing cylinder to rotate synchronously with the main shaft to maintain separation efficiency. During high-speed rotation, centrifugal force causes the opening and closing lifting plate to unfold and powerfully stir the material to form a three-dimensional vortex, improving grinding efficiency. At low speed or when stopped, the gravity block drives the lifting plate to automatically retract, creating an interference-free environment for the separation process. The lifting slider and the bearing ensure that the grinding cylinder lifts and lowers smoothly and rotates smoothly. This solves the problems of traditional equipment having single functions, poor motion coupling, and difficulty in achieving highly automated continuous operation. Attached Figure Description

Detailed Implementation

[0044] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Reference Figure 1 - Figure 12A fully automatic vortex polishing machine is provided, including a machine platform 1, a second telescopic cylinder 4 fixedly installed inside the machine platform 1 and a plurality of first telescopic cylinders 3. A servo motor 5 is fixedly installed at the output end of the second telescopic cylinder 4. The machine also includes a storage cylinder 2 fixedly connected to the top of the machine platform 1 and a grinding mechanism 6 disposed inside the storage cylinder 2.

[0046] Reference Figure 5 - Figure 10 The grinding mechanism 6 includes a grinding cylinder 63 and a rotating shaft 67. The grinding cylinder 63 is located inside the storage cylinder 2. The bottom of the rotating shaft 67 is fixedly connected to the output shaft of the servo motor 5. The top of the rotating shaft 67 is fixedly connected to a vortex disk 672. The outer wall of the vortex disk 672 is slidably connected to the inner wall of the grinding cylinder 63. The grinding mechanism 6 also includes a distribution cylinder 64 disposed at the bottom of the grinding cylinder 63. The top of the distribution cylinder 64 is fixedly connected to multiple material blocking rings 641. The inner wall of the vortex disk 672 is provided with multiple annular grooves 673. The inner walls of the multiple annular grooves 673 are slidably connected to the outer walls of the corresponding material blocking rings 641. The inner wall of the distribution cylinder 64 is provided with a distribution cavity 642. The outer wall of the distribution cavity 642 is provided with multiple mating interfaces 643.

[0047] Specifically, the rotating shaft 67 serves as the central hub for power transmission. Its upper end is connected to and drives the grinding component via the vortex disk 672, while its lower end is connected to the servo motor 5, transmitting the motor's torque upwards. Simultaneously, it acts as a motion carrier pushed and pulled by the second telescopic cylinder 4, achieving a combined rotational and lifting motion. During grinding, the vortex disk 672 acts as the rotating drive chassis for the grinding cylinder 63, transmitting torque to the grinding cylinder 63 and causing it to rotate together, forming a three-dimensional vortex under centrifugal force. During separation, it acts as a lifting disk for the workpiece and a filtering disk for the abrasive. When it is lifted separately by the rotating shaft 67, its disk surface lifts the workpiece that has completed grinding, while the annular groove 673 at its bottom disengages from the blocking ring 641 at the top of the distributing cylinder 64, forming an annular separation gap that allows the abrasive to pass through while the workpiece is retained.

[0048] Through telescopic drive and split nested structure, highly automated grinding and separation are achieved. The second telescopic cylinder 4 is linked with the first telescopic cylinder 3 to control the lifting and lowering of the vortex disk 672 and the grinding cylinder 63, completing the docking with the material storage system. Inside the equipment, through the precise nesting and separation structure of the vortex disk 672, the material distribution cylinder 64 and the material blocking ring 641, combined with the elastic support system of the support ring 65 and the telescopic spring 66, the precise opening and closing control of the separation gap is achieved. This achieves the effect of fully automatic completion of abrasive quantitative filling, efficient vortex grinding of workpieces, and automatic separation and recycling of abrasive and workpieces without intervention.

[0049] Reference Figure 5 - Figure 10The inner wall of the grinding cylinder 63 is fixedly connected with multiple sliding rods 632, and the two ends of each sliding rod 632 are fixedly connected with limit seats 631. The outer wall of the vortex disk 672 is provided with multiple recesses 674, and the sliding rods 632 are slidably engaged in the corresponding recesses 674. The vortex disk 672 and the grinding cylinder 63 are fixedly connected in the circumferential direction to transmit torque, and can slide relative to each other in the axial direction. The inner wall of the distributing cylinder 64 is provided with multiple sliding grooves 644, and the outer wall of the rotating shaft 67 is fixedly connected with multiple sliding plates 671. The outer wall of the sliding plates 671 is slidably connected to the inner wall of the corresponding sliding grooves 644. The distributing cylinder 64 rotates synchronously with the vortex disk 672 through the sliding grooves 644 and the sliding plates 671.

[0050] Specifically, the slide rod 632 is fixed to the inner wall of the grinding cylinder 63, and its cylindrical rod body is inserted into the notch 674 of the vortex disk 672 to transmit the rotational power of the vortex disk 672 to the grinding cylinder 63; the limiting seat 631 is fixed to both ends of the slide rod 632 to limit the travel range of the vortex disk 672 along the axial direction of the slide rod 632, preventing it from falling out or undergoing excessive displacement, and ensuring the reliability of the connection; the notch 674 is opened on the outer wall of the vortex disk 672 and forms a circumferential engagement with the slide rod 632; the sliding plate 671 is fixed to the outer wall of the rotating shaft 67 and cooperates with the sliding groove 644 on the inner wall of the distributing cylinder 64 to form a transmission pair that can slide relative to each other in the axial direction, directly transmitting the rotational motion of the rotating shaft 67 to the distributing cylinder 64.

[0051] The sliding engagement of the slide rod 632 and the notch 674, along with the transmission pairs of the sliding plate 671 and the sliding groove 644, enables precise linkage and power transmission of key moving components. The sliding rod 632 and the notch 674 of the vortex disk 672 are matched to fix them in the circumferential direction to transmit torque, while allowing relative sliding in the axial direction. This ensures that the grinding cylinder 63 can be reliably driven by the vortex disk 672 to complete the lifting and lowering motion. The matching of the sliding plate 671 and the sliding groove 644 allows the rotating shaft 67 to both drive the distributing cylinder 64 to rotate synchronously and achieve axial sliding. A composite transmission system integrating rotation drive, axial lifting and lowering, and motion decoupling is constructed, ensuring that the actions in each stage, such as grinding, separation, and material return, can be executed accurately, coordinatedly, and reliably, realizing a fully automated operation process.

[0052] Reference Figure 7 - Figure 9 The inner wall of the grinding cylinder 63 has multiple grooves 633. A free-rotating shaft 635 is fixedly connected to the inner wall of the grooves 633. An opening and closing lifting plate 634 and a gravity block 636 are fixedly connected to the outer wall of the free-rotating shaft 635. The opening and closing lifting plate 634 is located inside the grinding cylinder 63, and the gravity block 636 is located outside the grinding cylinder 63. The outer wall of the grinding cylinder 63 has multiple limiting grooves 637.

[0053] Specifically, the groove 633 is formed on the inner wall of the grinding cylinder 63, providing space for containment and constraint, and providing a mounting base for the free-rotating shaft 635 and its connected components; the opening and closing lifting plate 634 is fixedly connected to the free-rotating shaft 635 and located inside the grinding cylinder 63. When the grinding cylinder 63 rotates at high speed, the opening and closing lifting plate 634 unfolds outward around the free-rotating shaft 635 under the action of centrifugal force. Its plate surface is almost perpendicular to the cylinder wall, lifting up the abrasive and workpiece thrown to the vicinity of the cylinder wall by the centrifugal force and projecting them upward and inward, interrupting its simple circular motion. This creates a strong three-dimensional tumbling and collision vortex. When the grinding cylinder 63 stops or rotates at low speed, the opening and closing lifting plate 634 retracts around the axis under the gravity of the gravity block 636 and adheres to the cylinder wall. The gravity block 636 is fixedly connected to the free rotation shaft 635 and is located outside the grinding cylinder 63, providing a constant restoring torque as a power source to make the opening and closing lifting plate 634 tend to retract. The position of the limiting groove 637 corresponds to the internal groove 633 and the free rotation shaft 635, and its function is to set the maximum unfolding angle of the opening and closing lifting plate 634.

[0054] A dynamic opening and closing lifting plate 634 system is formed by groove 633, free rotating shaft 635, opening and closing lifting plate 634, gravity block 636 and limiting groove 637. When rotating at high speed, centrifugal force causes the opening and closing lifting plate 634 to expand outward around the axis, forcibly lifting and throwing the material to form a highly efficient three-dimensional vortex. When stopped or at low speed, the gravitational torque of gravity block 636 drives the lifting plate to automatically retract and fully embed into groove 633, thereby realizing efficient mixing in the grinding stage and interference-free automatic reset in the separation stage.

[0055] Reference Figure 5 The inner wall of the storage cylinder 2 is provided with multiple lifting grooves 27, and the inner wall of the lifting grooves 27 is slidably connected to the lifting sliders 61. The multiple lifting sliders 61 are fixedly connected to the bearings 62, and the inner wall of the bearings 62 is fixedly connected to the outer wall of the grinding cylinder 63.

[0056] Specifically, the lifting chute 27 is formed on the inner wall of the storage cylinder 2, providing precise axial guidance; the lifting slider 61 is slidably connected to the inner wall of the lifting chute 27, serving as an intermediate body for motion execution and load transmission; the bearing 62 serves as a slewing bearing, and its inner ring can rotate freely and at high speed with low resistance within its outer ring.

[0057] The lifting guide and rotation bearing system is formed by the lifting slide 27, the lifting slider 61 and the bearing 62; it realizes the stable and precise lifting movement of the grinding cylinder 63 in the vertical direction. At the same time, the bearing 62 supports the grinding cylinder 63 and allows it to have extremely low frictional resistance when rotating at high speed, ensuring the independent, stable and smooth execution of the two core actions of lifting and rotation, and supporting the dynamic needs of the entire workflow.

[0058] Reference Figure 5 - Figure 12A fixed ring 26 is fixedly connected to the inner wall of the storage cylinder 2, and a support ring 65 is slidably connected to the inner wall of the storage cylinder 2. A telescopic spring 66 is fixedly connected between the support ring 65 and the fixed ring 26. The top of the support ring 65 is rotatably connected to the bottom of the distributing cylinder 64, and the rotating shaft 67 passes through the center of the support ring 65.

[0059] Specifically, the fixed ring 26 serves as the static installation reference and reaction support for the entire elastic support system; the top of the support ring 65 is rotatably connected to the bottom of the distribution cylinder 64, directly bearing the weight and dynamic load of the distribution cylinder 64, the vortex disk 672, and related components, and transferring the load from above to the telescopic spring 66 below, while also transferring the preload support force of the spring upward to the distribution cylinder 64; the distribution cylinder 64 and the support ring 65 are rotatably connected by embedded ball bearings, allowing the distribution cylinder 64 to rotate freely at high speed under the drive of the rotating shaft 67, without transmitting this rotational torque to the support ring 65 and the telescopic spring 66 below.

[0060] The fixed ring 26, the support ring 65 and the telescopic spring 66 form an axial elastic support system. When the vortex disk 672 is pressed down, the telescopic spring 66 is compressed and stores energy. When the pressure is released, the telescopic spring 66 releases its elastic force and pushes the support ring 65 and the material distribution cylinder 64 to reset, ensuring that the lifting and lowering movement of the grinding cylinder 63 is accurate and stable, and always maintains the necessary support stiffness and dynamic reset capability.

[0061] Reference Figure 3 - Figure 5 The inner wall of the storage cylinder 2 is provided with a storage cavity 22, and a pusher block 23 is slidably connected to the inner wall of the storage cavity 22. The bottom of the pusher block 23 is fixedly connected to the output end of the first telescopic cylinder 3. The inner wall of the storage cavity 22 is provided with multiple discharge ports 24 and multiple return ports 25. The multiple return ports 25 are respectively connected to multiple docking ports 643. A sealing cover 21 is fixedly installed on the top of the storage cylinder 2.

[0062] The storage chamber 22, pusher block 23, first telescopic cylinder 3, discharge port 24, return port 25 and sealing cover 21 constitute a closed automatic abrasive supply and recovery system; it realizes automatic and quantitative filling and recovery of abrasive in a closed environment. The pusher block 23 pushes up to complete the filling and moves down to receive the returned abrasive; the sealing cover 21 ensures the airtightness of the operation process, effectively reduces noise and dust emission, and ensures operation safety and cleanliness.

[0063] Working principle of the invention:

[0064] Initially, the grinding cylinder 63 is connected to the lifting slider 61 via a bearing 62 fixed to its outer wall. The lifting slider 61 is slidably connected to the lifting groove 27 on the inner wall of the storage cylinder 2. The vortex disk 672 is located at the bottom inside the grinding cylinder 63. Its outer wall is slidably engaged with the slide rod 632 on the inner wall of the grinding cylinder 63 via a notch 674 to achieve circumferential fixation. The bottom of the vortex disk 672 is nested and slidably connected to the material blocking ring 641 at the top of the distribution cylinder 64 via its annular groove 673, forming a sealed grinding base. The distribution cylinder 64 is supported on the support ring 65. A telescopic spring 66 is installed at the bottom of the support ring 65. Initially, the spring is in a pre-compressed state, providing upward elastic support.

[0065] The second telescopic cylinder 4 is activated, and its output end drives the servo motor 5 and the rotating shaft 67 fixed to its output shaft to descend as a whole. The rotating shaft 67 drives the vortex disk 672 at its top to slide downward. Since the vortex disk 672 is circumferentially fixed to the grinding cylinder 63 and limited by the restricted seat 631, the downward movement of the vortex disk 672 drives the entire grinding cylinder 63 to descend synchronously along the lifting slide groove 27 via the lifting slider 61. The descent of the grinding cylinder 63 lowers its top opening to align with the discharge port 24 on the inner wall of the storage cylinder 2. At this time, the first telescopic cylinder 3 is activated, driving the pusher block 23 in the storage cavity 22 to move upward, pushing the pre-stored abrasive in the cavity into the docked grinding cylinder 63 through the discharge port 24, completing the automatic filling of abrasive.

[0066] After the abrasive is loaded, the second telescopic cylinder 4 drives the servo motor 5 and the rotating shaft 67 to drive the vortex disk 672 to rise and reset. As the vortex disk 672 moves upward, the previously compressed telescopic spring 66 releases its elastic potential energy and pushes the material distribution cylinder 64 upward. The material distribution cylinder 64 then pushes the grinding cylinder 63 to slide upward until it is completely reset to the initial high position. At this time, the workpiece to be processed can be placed into the grinding cylinder 63, which is already filled with abrasive, through the top opening.

[0067] Subsequently, the servo motor 5 starts and drives the vortex disk 672 to rotate at high speed through the rotating shaft 67. The vortex disk 672 is engaged with the notch 674 circumferentially through the slide rod 632, which transmits the torque to the grinding cylinder 63, causing the grinding cylinder 63 to rotate together. Under the action of strong centrifugal force, the multiple opening and closing lifting plates 634 on the inner wall of the grinding cylinder 63 unfold outward around its free rotation axis 635, continuously lifting and throwing the abrasive and workpiece inside the cylinder, forming a violent three-dimensional vortex motion, which performs efficient and uniform finishing on the surface of the workpiece.

[0068] After the set grinding time is reached, the servo motor 5 decelerates and stops. As the speed decreases, the gravity block 636 on the outside of the opening and closing lifting plate 634 drives the lifting plate to rotate and retract under the action of gravity, and completely embeds it into the groove 633 on the inner wall of the grinding cylinder 63 to avoid interfering with subsequent separation.

[0069] The second telescopic cylinder 4 is activated again, driving the servo motor 5 and the rotating shaft 67 to move the vortex disk 672 upwards by a precise distance. Since the vortex disk 672 and the grinding cylinder 63 are axially slidingly connected, this action causes the vortex disk 672 to move upwards relative to the grinding cylinder 63 and the distribution cylinder 64. The disk surface of the vortex disk 672 lifts the workpiece that has settled at the bottom upwards. At the same time, an annular separation gap appears between the vortex disk 672 and the top of the distribution cylinder 64. The abrasive with a lower density enters the distribution chamber 642 of the distribution cylinder 64 through this gap under the action of gravity.

[0070] At this time, the servo motor 5 can be controlled to restart in low-speed mode, driving the vortex disk 672 and the distribution cylinder 64 to rotate simultaneously via the rotating shaft 67. The vortex disk 672, in turn, drives the grinding cylinder 63 to rotate slowly together via the slide rod 632. The slight centrifugal force and vibration effect help the abrasive to fully detach from the workpiece surface and accumulation area, reducing adhesion and allowing the abrasive to flow more smoothly and thoroughly into the distribution chamber 642 through the annular gap. At the same time, the rotational motion helps the abrasive to diffuse towards the side wall of the distribution cylinder 64, ensuring that the abrasive enters the return port 25 more smoothly and evenly through the interface 643 of the side wall.

[0071] The abrasive entering the distribution chamber 642 flows through the interface 643 on its side wall into the return port 25 on the inner wall of the storage cylinder 2, and finally automatically flows back to the storage chamber 22; the first telescopic cylinder 3 drives the pusher block 23 to move down, receive and store the returned abrasive, and put it in a standby state, realizing the automatic recycling and reuse of abrasive; the operator can easily take out the processed workpiece that has been lifted to an easily accessible position by the vortex disk 672.

[0072] At this point, one cycle is complete, all actuators are reset, the equipment returns to its initial state, and it is ready for the next operation; the sealing cover 21 on the top of the storage cylinder 2 ensures the airtightness, low noise, and safety of the operation throughout the process.
