Description

Technical Field

[0001] The present invention relates to the technical field of polishing machines, in particular to an 8K mirror grinding head and a polishing machine for polishing stainless steel. Background Art

[0002] High-quality mirror polishing of stainless steel products is one of the key factors to ensure their wide application in industries such as construction, automotive industry, shipbuilding, marine equipment, mechanical equipment and chemical equipment. Polished 8K mirror panels are ground to make the surface as bright as a mirror, with high plasticity, toughness and mechanical strength.

[0003] During the polishing process of stainless steel, the polishing grinding head is easily damaged due to long-term high-speed friction, thus requiring the polishing grinding head to be replaced. In order to improve the efficiency of disassembly and assembly of the polishing grinding head, the prior art has achieved the effect of quick disassembly and assembly between the polishing grinding head and the connecting shaft by providing a quick-release structure between the connecting shaft and the polishing grinding head. However, the quick-release structure in the prior art is exposed to the outside. Since chips are easily generated during the polishing of stainless steel, the flying chips will also fall into the quick-release structure. Over time, a large amount of stainless steel chips will accumulate in the quick-release structure. When the quick-release structure is subsequently used to replace the polishing grinding head, the chips may cause wear and jamming of various parts of the quick-release structure, thereby affecting the use. In addition, in the prior art, when the polishing grinding head is connected to the connecting shaft, a sealing mechanism is not provided around the through hole for injecting polishing liquid. This causes the polishing liquid to overflow at the connection between the polishing grinding head and the connecting shaft, and cannot be fully applied to the stainless steel, thereby resulting in waste of polishing liquid.

[0018] The present invention provides a technical solution: as Figures 1 - 14 shown, a stainless steel polishing 8K mirror grinding head and a polishing machine include a connecting seat 1 and a polishing grinding head 2.

The two L-shaped rods 19 are respectively slidably installed inside the two curved grooves 20. Four uniformly distributed transmission grooves 21 are formed at the bottom of the cylinder body two 15. The four transmission rods 14 are respectively slidably installed inside the four transmission grooves 21.

[0022] An annular limiting plate 22 is fixedly installed at the bottom of the cylinder body one 7. An annular limiting groove 23 is formed at the top of the transition plate 16. The annular limiting plate 22 is movably installed inside the annular limiting groove 23. The cylinder body one 7 is rotationally connected to the transition plate 16 through the mutual cooperation of the annular limiting groove 23 and the annular limiting plate 22.

[0023] The sealing mechanism includes a sealing gasket 24, a mounting plate 25 fixedly installed on one side of the sealing gasket 24, and an H-shaped flipping plate 26 rotatably installed inside the connecting seat 1. Two strip-shaped grooves 27 are formed at both ends of the H-shaped flipping plate 26. A T-shaped rod one 28 is fixedly installed on the side of the mounting plate 25 away from the sealing gasket 24. A T-shaped rod two 29 is fixedly installed at the bottom of the transmission rod 14. The two ends of the T-shaped rod one 28 and the T-shaped rod two 29 are respectively slidably installed inside their corresponding strip-shaped grooves 27.

[0024] Shielding plates two 30 are fixedly installed on the outside of both push rods 8. Mounting grooves 31 are formed at both ends of the connecting seat 1. The two shielding plates two 30 are respectively installed inside the two mounting grooves 31. The two mounting grooves 31 are respectively communicated with the two adjusting grooves. A shielding plate one 32 is fixedly sleeved on the outside of the connecting seat 1. The tops of the four clamping blocks 5 are all fixedly connected to the shielding plate one 32.

[0025] A through hole one 33 is formed in the middle of the connecting seat 1. A through hole two 34 is formed in the middle of the polishing grinding head 2. The through hole one 33 and the through hole two 34 have the same diameter. A plurality of uniformly distributed drainage grooves 35 are formed at the bottom of the polishing grinding head 2. One ends of the plurality of drainage grooves 35 close to the through hole one 33 are all communicated with the through hole one 33.

[0026] Working principle: Connect the connecting seat 1 with the driving device in the polishing machine. Initially, the two push rods 8 are respectively located inside the two clamping grooves II 11. At this time, the first cylinder 7 and the transition plate 16 are also at the highest positions, and the four positioning rods 9 are retracted into the connecting seat 1. When installing the connecting seat 1 and the polishing head 2, first align the four clamping grooves 4 in the polishing head 2 with the four clamping blocks 5 at the bottom of the connecting seat 1 respectively, and then sleeved the polishing head 2 outside the connecting seat 1. At this time, the bottom of the connecting seat 1 is located inside the circular groove 3, the four clamping blocks 5 are respectively located inside the four clamping grooves 4, and the four positioning grooves 6 correspond to the four push rods 8 one by one. At this time, the bottom of the first baffle 32 is in contact with the top of the polishing head 2 to block the connection between the connecting seat 1 and the polishing head 2.

[0027] Subsequently, press down the two push rods 8. The two push rods 8 drive the first cylinder 7 to move downward. During the movement of the two push rods 8, the two corresponding second baffles 30 are always driven to move inside their respective installation grooves 31. The setting of the two second baffles 30 prevents stainless steel chips from entering the connecting seat 1 through the adjustment grooves. As the first cylinder 7 descends, the transition plate 16 slides downward along the two guide rods 17 and compresses the two springs 18. As the transition plate 16 descends, the two L-shaped rods 19 slide downward inside their respective curved grooves 20, and the second cylinder 15 is forced to rotate counterclockwise. The second cylinder 15 drives the four transmission grooves 21 to rotate synchronously, and the four guide rods 17 drive the corresponding positioning rods 9 to expand and move outward at the same time. The four positioning rods 9 are inserted into their respective positioning grooves 6. When the two push rods 8 descend to the bottom, then move clockwise along the two sliding grooves 12. The first cylinder 7 drives the annular limiting plate 22 to rotate inside the annular limiting groove 23, and the transition plate 16 will not rotate, so as not to affect the position of the four positioning rods 9 at its bottom. When the two push rods 8 rotate to the limit position, release the two push rods 8. Under the action of the two springs 18, the two push rods 8 move into their respective clamping grooves I 10. During this process, the four positioning rods 9 still do not change their positions and always remain in the state of being inserted into their respective positioning grooves 6. The gap between the polishing head 2 and the connecting seat 1 is small, and with the cooperation of the first baffle 32 and the second baffle 30, the chips generated by polishing the stainless steel will not fall on the connection between the polishing head 2 and the connecting seat 1, thus ensuring that the two push rods 8 can smoothly operate the transmission mechanism and enabling the transmission mechanism and the four positioning rods 9 to always maintain a good quick-release efficiency for the polishing head 2.

[0028] During the process of the two push rods 8 driving the cylinder body one 7 to move downward, due to the counterclockwise rotation of the cylinder body two 15, the four positioning rods 9 all slide outward, and the four positioning rods 9 drive the corresponding sealing mechanisms to move. The movement process of one of the sealing mechanisms is as follows: As the positioning rod 9 moves outward, the transmission rod 14 at one end of the positioning rod 9 moves outward, thereby driving the T-shaped rod two 29 at its bottom to move synchronously. The bottom of the T-shaped rod two 29 slides inside the corresponding strip-shaped groove 27, thereby driving the H-shaped turning plate 26 to rotate. The top of the H-shaped turning plate 26 moves outward, and its bottom drives the T-shaped rod one 28 to move inward. The mounting plate 25 then pushes the sealing gasket 24 to move inward. The movement processes of the other three sealing mechanisms are all as described above. As the four sealing gaskets 24 approach synchronously, the sides between adjacent sealing gaskets 24 are squeezed, the top of the four sealing gaskets 24 is squeezed against the connecting seat 1, and the bottom is squeezed against the bottom of the annular sealing groove 13, thereby sealing between the through hole one 33 and the through hole two 34, avoiding the waste caused by the overflow of the polishing liquid, and enabling the polishing liquid to act on the stainless steel.

[0029] When disassembling the polishing head 2 and the connecting seat 1, by pressing down the two push rods 8, the two push rods 8 can enter the clamping groove two 11 from the clamping groove one 10.
