Description

Technical Field

[0001] The present invention belongs to the technical field of grinding and polishing machines, and relates to an annular magnetic grinding and polishing machine. Background Art

[0002] In the field of machining, the surface treatment of products such as tensile parts or sheet metal cross-section parts is crucial. Traditional grinding processes face many challenges when dealing with such workpieces. On the one hand, previous grinding equipment mostly adopted a single grinding station or a simple linear station layout, and the workpieces needed to be frequently transferred between different equipment, with cumbersome operations and low efficiency. For example, in some small processing factories, grinding equipment operated manually by workers is still used. Workers need to place the workpieces one by one under the grinding tools for processing, which not only has a large labor intensity but also a slow processing speed, making it difficult to meet the needs of large-scale production.

[0003] On the other hand, traditional grinding equipment has great defects in ensuring grinding uniformity. The movement trajectories of the grinding media in traditional equipment are relatively single, which easily leads to over-grinding of some areas on the workpiece surface and insufficient grinding of some areas. For example, in common fixed disk-type grinding equipment, due to the fixed position of the disk, the movement range of the grinding needles under the action of the magnetic field is limited, and it is difficult to fully cover the workpiece surface, resulting in inconsistent surface finish of the workpiece and seriously affecting product quality.

[0033] Please refer to Figures 1 to 6 , in the embodiments of the present invention, an annular magnetic abrasive polishing machine includes: an annular frame 1 with an annular structure, on which a set of discharge positions and multiple sets of grinding positions are preset along its annular shape;

[0034] Multiple sets of grinding barrels 3 are arranged on the annular frame 1, and a transmission mechanism is provided to drive the grinding barrels 3 to move circularly along its annular shape;

[0035] Polishing needles for grinding products are placed inside the grinding barrels 3, and on each grinding position of the annular frame 1, a disk mechanism is provided to control the magnetization and demagnetization movements of the polishing needles inside the grinding barrels 3;

[0036] During operation, the products to be polished (drawn parts or sheet metal cross-section parts) and the polishing needles are placed into the grinding barrels 3, and the transmission mechanism drives each grinding barrel 3 to move circularly and enter each grinding position in sequence; meanwhile, the disk mechanism in the grinding position works to generate a magnetic field; and during the process of the grinding barrel 3 entering and leaving the grinding position, due to the change in the magnetic field position of the polishing needles inside the grinding barrel 3, magnetization and demagnetization movements will occur;

[0037] Among them, during the magnetization movement, the polishing needles obtain energy under the action of the magnetic field force and generate high-speed tumbling, swinging and other actions, so that the polishing needles are in full contact with the workpiece surface and generate frictional force to achieve the grinding work.

[0038] The demagnetization movement changes the movement state of the polishing needles to prevent them from continuously acting at the same position and ensure the uniformity of grinding.

[0039] During the process of the grinding barrel 3 moving cyclically at each grinding position, the magnetization and demagnetization movements will alternate continuously, making the movement trajectory of the polishing needles in the grinding barrel 3 complex and variable, capable of covering different parts of the workpiece, thereby achieving comprehensive and meticulous grinding of the workpiece surface, effectively removing burrs, oxide layers, etc., and improving the surface finish of the workpiece;

[0040] At the discharge position of the annular frame 1, a tipping mechanism is provided for realizing the tipping and discharging work of the grinding barrel 3. After the grinding work is completed, the grinding barrel 3 moves to the discharge position, and the tipping mechanism drives the grinding barrel 3 to tilt, facilitating the material taking work inside the grinding barrel 3 and the discharge of the polishing liquid inside the barrel, improving the overall processing efficiency.

[0041] Furthermore, the transmission mechanism includes: a transmission chain 11 arranged in the middle of the annular frame 1, a driving sprocket group 10, and a driving reduction motor 8;

[0042] The driving sprocket group 10 includes: a driving sprocket and a driven sprocket, and the transmission chain 11 is arranged between the driving sprocket and the driven sprocket; among them, the driving sprocket is connected to the output shaft of the driving reduction motor 8 through a coupling, and is driven by the driving reduction motor 8 to realize the transmission work of the transmission chain 11;

[0043] A group of grinding barrel support arms 4 are installed on the grinding barrel 3, and the rear end of the grinding barrel support arm 4 is connected and matched with the link ear of the transmission chain 11, thereby realizing the effect of the transmission chain 11 driving the grinding barrel 3 to move cyclically.

[0044] Even further, a table waterproof plate 2 that covers all positions other than the discharge position is provided on the working surface of the annular frame 1; through the table waterproof plate 2, impurities such as polishing liquid and debris can be effectively prevented from invading the interior of the grinding equipment and causing unnecessary damage to the equipment.

[0045] Preferably, a moving pulley (not shown in the figure) is provided at the lower end of the grinding barrel 3, and the lower end of the moving pulley contacts the table waterproof plate 2; by means of the moving pulley, the effect of rolling friction replacing sliding friction is achieved, reducing the friction between the grinding barrel 3 and the machine table and extending the service life of the whole machine.

[0046] Preferably, a protective cover 6 that covers and protects the transmission mechanism is also provided at the center position of the working surface of the annular frame 1; in cooperation with the table waterproof plate 2, comprehensive protection of the annular frame 1 is achieved, preventing personal injury caused by the operation of the transmission mechanism.

[0047] Furthermore, the disk mechanism includes: a disk drive motor arranged at the lower end of the grinding position and a drive disk 9 installed on the output end of the disk drive motor; when working, the drive disk 9 is energized and driven to rotate by the disk drive motor to generate a working magnetic field; and the transmission mechanism is cooperated to realize the magnetic movement and demagnetization movement of the polishing needle in the grinding barrel 3, so as to achieve the technical purpose of grinding and polishing.

[0048] It should be noted that the drive disk 9 has the same structure as a conventional disk. The drive disk 9 is usually powered by a slip ring device when in a rotating state; the slip ring device is mainly composed of a fixed part and a rotating part. The fixed part is connected to an external power source, and the rotating part is connected to the rotating shaft of the drive disk 9 and rotates with the drive disk 9. When current flows from an external power source into the fixed part of the slip ring, the current can be transmitted to the rotating part through special conductive materials and contact structures, and then to the drive disk 9, so that the drive disk 9 obtains electrical energy while rotating and generates a magnetic field.

[0049] Furthermore, the turning mechanism comprises: a turning cylinder 7 fixedly mounted on the annular frame 1, a group of turning arm 13 is mounted on the piston rod of the turning cylinder 7,

[0050] The flipper arm 13 includes: a flip push plate 41 of an arc structure and a flip fixing rod 42 fixedly mounted on the annular frame 1, one end of the flip push plate 41 is sleeved on the flip fixing rod 42, so that the flip push plate 41 can rotate around it; the piston rod of the flip cylinder 7 is hingedly matched with the middle end of the flip push plate 41; when working, the flip cylinder 7 pushes out the piston rod, so that the flip push plate 41 rotates upward with the flip fixing rod 42 as the center point to realize the flipping action;

[0051] The grinding barrel support arm 4 is a semi-enclosed structure in the shape of a Chinese character "凵". The rear end of the grinding barrel support arm 4 is connected and matched with the chain ear of the transmission chain 11. Both sides of the grinding barrel support arm 4 extend to both sides of the grinding barrel 3. Both sides of the grinding barrel 3 are provided with grinding barrel flanges 5 that are hingedly matched with the grinding barrel support arm 4, so that the grinding barrel 3 can achieve a rotation effect with the grinding barrel flange 5 as the center point.

[0052] After the grinding barrel 3 enters the processing position of the discharge position, the flip push plate 41 is driven to flip upward by the flip cylinder 7, and one side of the grinding barrel 3 is lifted up, so that the grinding barrel 3 is tilted forward at a certain angle, which is convenient for taking materials from the grinding barrel 3 and discharging the polishing liquid in the barrel under the action of gravity; and, in actual work, in order to prevent the grinding barrel 3 from tilting backward, a support plate for supporting the grinding barrel 3 can also be provided at the bottom of the rear end of the grinding barrel support arm 4, so as to prevent the grinding barrel 3 from tilting backward when entering the discharge position.

[0053] Preferably, a water supply pipe 12 and a water supply pump 14 for supplementing the polishing liquid are further provided at the discharge position; the water supply pump 14 is connected to an external polishing liquid supply device through a pipeline. After the polishing liquid in the grinding barrel 3 is discharged, the clean polishing liquid is pumped into the grinding barrel 3 through the water supply pipe 12 by the water supply pump 14, improving the overall grinding work efficiency.

[0054] Furthermore, sensors (not shown in the figure) are installed on the annular frame 1 corresponding to the positions of the discharge position and each grinding position; after the sensors sense that the grinding barrel 3 is in place, the grinding barrel 3 in the corresponding working station is polished or discharged.

[0055] Furthermore, the annular frame 1 adopts an elliptical frame structure, and the discharge position is arranged at one end of the elliptical annular frame 1. Compared with other annular structures, the overall floor area is smaller, which can better save the workshop space and make the workshop layout more reasonable.

[0056] It should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the presence of additional identical elements in the process, method, article or device including the element.
