Description

[0001] The present invention relates to the technical field of steel grating grinding, and specifically to a side grinding device for hot-dip galvanized steel gratings. Background Art

[0002] During the hot-dip galvanizing process, sharp burrs or uneven zinc nodules may form on the sides of the steel grating.

Detailed implementation manners

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] In one embodiment, please refer to Figures 1 - 10 , a side grinding device for hot-dip galvanized steel grating, including a grinding platform 1. The middle part of the grinding platform 1 is rotationally connected with a rotating sleeve 25. The rotating sleeve 25 is vertically and rotationally connected to the middle part of the grinding platform 1. The device further includes a grinding mechanism 2 and a clamping mechanism 3;

[0027] The grinding mechanism 2 includes a main shaft 24 which is vertically arranged and rotatably connected to the middle of the rotating sleeve 25. Rotating locking components 23 are arranged on the left and right sides of the rotating sleeve 25. The rotating locking components 23 can fix the main shaft 24 and the rotating sleeve 25 so that the main shaft 24 and the rotating sleeve 25 rotate synchronously, or the rotating locking components 23 can fixedly connect the rotating sleeve 25 to the grinding platform 1, so that the rotating sleeve 25 stops rotating and the main shaft 24 rotates independently. A protruding cantilever 26 is horizontally arranged on the upper side surface of the rotating sleeve 25. A vertically arranged tensioning rod 18 is rotatably connected to one end of the protruding cantilever 26 away from the rotating sleeve 25. A driving pulley 27 is fixedly connected to the upper end of the main shaft 24. The driving pulley 27 is connected to a driven pulley 28 through a synchronous belt 29. The driven pulley 28 is fixedly connected to the upper end of the tensioning rod 18. And a sliding seat 30 is slidably connected to the middle of the protruding cantilever 26. The sliding seat 30 is fixedly connected to one side of the synchronous belt 29. Therefore, when the synchronous belt 29 rotates, the sliding seat 30 will slide left and right along the protruding cantilever 26. A grinding head 31 is arranged above the sliding seat 30, so that the grinding head 31 is driven to move horizontally through the synchronous belt 29. And a commutation component 32 is arranged above the sliding seat 30. The commutation component 32 can make the orientation of the grinding head 31 parallel or perpendicular to the protruding cantilever 26;

[0028] The clamping mechanism 3 includes a side plate 6 which is vertically arranged at the middle of the rear side edge of the grinding platform 1. A cantilever beam 7 arranged in the front-back direction is fixedly connected to the upper end of the side plate 6. A pressing plate 8 is arranged on the front side below the cantilever beam 7. The pressing plate 8 can move up and down, so as to fix the circular plate 4 and the flat plate 5 through the pressing plate 8. An auxiliary support component 36 which cooperates with the pressing plate 8 is arranged at the end of the main shaft 24;

[0029] After the rotating sleeve 25 and the main shaft 24 are fixed by the rotating locking component 23, the rotating sleeve 25 and the main shaft 24 rotate synchronously, so that the protruding cantilever 26 rotates synchronously with the main shaft 24, that is to say, the grinding head 31 rotates along the center of the main shaft 24, so as to realize the grinding process of the side surface of the circular plate 4 by the grinding head 31. After the rotating sleeve 25 and the grinding platform 1 are fixed by the rotating locking component 23, at this time, the rotating sleeve 25 stops rotating. When the main shaft 24 rotates at this time, the main shaft 24 drives the sliding seat 30 to slide along the protruding cantilever 26 through the synchronous belt 29, so that the grinding head 31 grinds the side edge of the flat plate 5. And in order to better deflect the protruding cantilever 26, rollers are arranged on the lower surface of the protruding cantilever 26. The rollers can roll on the upper surface of the grinding platform 1, improving the stability of the protruding cantilever 26.

[0030] In a case of this embodiment, the rotation locking assembly 23 includes fixed plates 20 disposed on the left and right sides at the lower end of the rotating sleeve 25. The lower ends of the fixed plates 20 are threadedly connected with tensioning lead screws 21 arranged in the left and right directions. And limit seats 22 are provided on both the left and right sides of the rotating sleeve 25. The upper ends of the limit seats 22 are fixedly connected to the lower surface of the grinding platform 1. Tensioning blocks 19 are provided at both the left and right ends of the tensioning lead screw 21. The tensioning blocks 19 are made of rubber material, which improves the fixing effect of the tensioning blocks 19 with the main shaft 24 and the limit seats 22. That is to say, when the tensioning lead screw 21 drives the tensioning block 19 to press against the outside of the main shaft 24, the main shaft 24 rotates synchronously with the rotating sleeve 25. When the tensioning lead screw 21 drives the tensioning block 19 to press tightly against the limit seat 22, at this time, the rotating sleeve 25 is fixed relative to the grinding platform 1, and at this time, the rotating sleeve 25 stops rotating.

[0031] In a case of this embodiment, a motor suspension bracket 14 rotatably connected to the main shaft 24 is provided on one side of the grinding platform 1 close to the ground. The motor suspension bracket 14 is a U-shaped structure with an upward opening. The upper end of the motor suspension bracket 14 is fixed to the lower surface of the grinding platform 1. The lower end of the main shaft 24 is rotatably connected to the middle of the motor suspension bracket 14. Therefore, the main shaft 24 can rotate better. And a rotation drive motor 15 is provided on the motor suspension bracket 14. The output shaft of the rotation drive motor 15 is fixedly connected with a driving gear 16. The driving gear 16 is meshed with a driven gear 17 fixedly connected to the main shaft 24. Therefore, the rotation drive motor 15 can make the main shaft 24 rotate through a gear transmission method, and further realize the movement of the grinding head 31.

[0032] In a case of this embodiment, the commutation assembly 32 includes a deflection rod 41 rotatably connected to the sliding seat 30. The deflection rod 41 is vertically arranged at the rear end of the sliding seat 30. A deflection seat 42 is fixedly connected to the upper end of the deflection rod 41. A grinding head 31 is rotatably connected to the side surface of the deflection seat 42. At this time, the deflection seat 42 is placed in the front-rear direction, the grinding head 31 is placed on the left side of the deflection seat 42, a grinding motor 43 is arranged on the right side of the deflection seat 42. An output shaft of the grinding motor 43 is fixedly connected with a first bevel gear 44, and the first bevel gear 44 is meshed with a second bevel gear 45 that rotates synchronously with the grinding head 31. Therefore, the grinding motor 43 enables the grinding head 31 to rotate at a high speed through a gear transmission method. And limiting holes 39 are arranged on both the rear side surface and the right side surface of the sliding seat 30. An L-shaped limiting frame 37 is arranged at the lower end of the deflection rod 41. A horizontally arranged limiting rod 38 is slidably connected to the limiting frame 37. When the grinding head 31 is arranged towards the left, at this time, the limiting rod 38 can be inserted into the limiting hole 39 at the rear end of the sliding seat 30 to achieve the effect of orientation limitation. At the same time, when the grinding head 31 is arranged towards the rear, at this time, the limiting rod 38 can be inserted into the limiting hole 39 on the right side of the sliding seat 30. And a limiting ring is arranged outside the limiting rod 38. A limiting spring 40 is arranged between the limiting ring and the limiting frame 37. The limiting spring 40 is sleeved outside the limiting rod 38, and the limiting spring 40 will push the limiting rod 38 to move towards the direction of the limiting hole 39. Therefore, when there is no external force, the limiting rod 38 will always maintain the state of being inserted into the limiting hole 39, improving the stability of direction locking.

[0033] In a case of this embodiment, a rotating disk 13 is provided at the lower part of the front side of the cantilever beam 7. Fixed seats 12 are provided on both sides of the rotating disk 13. The fixed seats 12 can rotate along the rotating disk 13. A telescopic slide rod 11 is vertically provided on the lower surface of the fixed seat 12. The extending rod of the telescopic slide rod 11 extends downward. The extending rod of the telescopic slide rod 11 is fixedly connected to the upper surface of the pressing plate 8. A tension spring is provided inside the telescopic slide rod 11. The tension spring pulls the extending rod of the telescopic slide rod 11 upward. That is to say, the tension spring will keep the tendency of pulling the pressing plate 8 upward. A pressing cylinder 10 is vertically provided on the front side of the cantilever beam 7. The rotating disk 13 is of an annular structure. The pressing cylinder 10 is located at the central position of the rotating disk 13. A pressure head 9 is fixedly connected to the piston rod of the pressing cylinder 10. When the piston rod of the pressing cylinder 10 extends, the pressure head 9 will contact the pressing plate 8, and the pressure head 9 will push the pressing plate 8 downward. That is to say, the cooperation of the pressing cylinder 10 and the telescopic slide rod 11 can control the up and down movement of the pressing plate 8. The auxiliary support assembly 36 includes a deflection plate 33 rotatably connected to the upper end of the main shaft 24. The rear end of the deflection plate 33 is rotatably connected to a rotating seat 34. The rotating seat 34 is collinear with the center of the rotating disk 13. The upper part of the rotating seat 34 is fixedly connected to the end of a support plate 35. When the circular plate 4 needs to be fixed, the support plate 35 and the deflection plate 33 are both rotated to the front-back facing state, and at this time the pressing plate 8 is rotated to the front-back facing state. The center of the circular plate 4 is coincided with the center of the main shaft 24. At this time, the circular plate 4 is placed on the support plate 35. The downward movement of the pressing plate 8 can complete the clamping process of the circular plate 4. When the flat plate 5 needs to be fixed, the deflection plate 33 can be rotated to the backward state, and the support plate 35 can be rotated to the right state. At this time, the pressing plate 8 is rotated to the left-right facing state. The flat plate 5 is placed on the support plate 35. At this time, after the pressing plate 8 moves downward, the flat plate 5 can be fixed.

[0034] During the implementation of this embodiment, a support device is provided below the grinding platform 1, so that the grinding platform 1 can maintain a horizontal state for grinding the plate.

[0035] For the circular side grinding process, the piston rod of the pressing cylinder 10 retracts, the pressure head 9 disengages from the pressing plate 8, and the pressing plate 8 is rotated to a state where it faces forward and backward. The deflecting plate 33 is rotated to a backward state, and the supporting plate 35 is rotated to a forward state. At this time, the deflecting plate 33 and the supporting plate 35 overlap and maintain a state of facing forward and backward. Take out the circular plate 4, align the center of the circular plate 4 with the main shaft 24, reverse-start the pressing cylinder 10, and the pressure head 9 moves downward so that the pressing plate 8 tightly presses on the upper surface of the circular plate 4. Rotate the grinding head 31 to a state where it faces left. At this time, rotate the fixed tightening screw rod 21 so that the rotating sleeve 25 is fixed to the grinding platform 1. The rotation drive motor 15 drives the main shaft 24 to rotate, and the main shaft 24 makes the sliding seat 30 move to the left through the synchronous belt 29. The grinding head 31 abuts against the side of the circular plate 4. At this time, reverse-rotate the tightening screw rod 21, and the rotating sleeve 25 is fixed to the main shaft 24. Start the grinding motor 43, and the grinding head 31 starts to rotate self - sufficiently. And start the rotation drive motor 15 again. The rotating sleeve 25 rotates with the main shaft 24, and the grinding head 31 rotates around the circular plate 4, thus realizing the grinding process of the side of the circular plate 4. And the grinding head 31 and the deflecting seat 42 can be set to be floating, with a spring inside, so that the grinding head 31 can maintain a certain pressure and abut against the side of the circular plate 4 for grinding treatment.

[0036] For the straight - edge grinding process, the piston rod of the pressing cylinder 10 retracts, the pressure head 9 disengages from the pressing plate 8, and the pressing plate 8 is rotated to a state where it faces right. The deflecting plate 33 is rotated to a backward state, and the supporting plate 35 is rotated to a state where it faces right. At this time, the deflecting plate 33 and the supporting plate 35 are in an L - shaped state. Rotate the grinding head 31 to a backward state, and place the flat plate 5 with its left - right orientation on the supporting plate 35. The grinding head 31 is slightly retracted into the deflecting seat 42 under pressure. Reverse - start the pressing cylinder 10, and the pressure head 9 moves downward so that the pressing plate 8 tightly presses on the upper surface of the flat plate 5. At this time, rotate the fixed tightening screw rod 21 so that the rotating sleeve 25 is fixed to the grinding platform 1. Start the grinding motor 43, and the grinding head 31 starts to rotate self - sufficiently. And start the rotation drive motor 15 again. The main shaft 24 makes the sliding seat 30 slide left - right along the extended cantilever 26 through the synchronous belt 29, so that the grinding head 31 transversely moves left - right along the front side edge of the flat plate 5 to realize the grinding process.

[0037] The present invention is applicable to a side - grinding device for hot - dip galvanized steel grating. By setting the rotation locking component 23, the rotating sleeve 25 is fixed to the main shaft 24 and the grinding platform 1 respectively, so that the main shaft 24 can drive the grinding head 31 to rotate circumferentially and linearly translate. Thus, the grinding head 31 can effectively grind the circular side of the circular plate 4 and the straight edge of the flat plate 5 respectively, enabling the entire grinding device to complete the grinding of circular edges and straight edges and improving the grinding efficiency.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
