[0030] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail below.

[0031] This invention discloses a deburring device for sheet metal. (Refer to...) Figures 1-6 A deburring device for sheet metal includes a support 1 and a base plate 2. The base plate 2 is installed at the bottom of the support 1 and a storage structure is provided on the base plate 2.

A clamping and moving structure is provided in each deburring cavity 5. A top cover 3 is fixedly installed in the middle of the support 1. A deburring structure is provided on the top cover 3 and a shielding and collecting structure is provided on the top cover 3.

[0032] The clamping and moving structure includes two sets of guide rods 6 connected between the inner walls of the front and rear sides of the deburring chamber 5. Each set of two guide rods 6 is movably fitted with a moving seat 7. A fixed frame 8 is set on the moving seat 7 through a flipping structure. A cylinder 9 is fixedly installed on the inner wall of the fixed frame 8. One end of the output shaft of the cylinder 9 is connected to the clamping plate 10. Two first electric push rods 21 are installed on the inner wall of the front side of the deburring chamber 5. One end of the output shaft of the first electric push rod 21 is connected to the moving seat 7.

[0033] The flipping structure includes a flipping rod 11 rotatably connected to the movable seat 7. One end of the flipping rod 11 is fixedly connected to the fixed frame 8. A movable ring 12 is movably sleeved on the flipping rod 11. A rod 13 is fixedly inserted into the movable ring 12. A flipping groove 14 is opened on the flipping rod 11. One end of the rod 13 is movably inserted into the flipping groove 14. Two push-pull rods 15 are connected to the movable ring 12. Fixed blocks 16 are set in the middle of the upper and lower surfaces of the movable seat 7. The push-pull rods 15 movably pass through the push-pull rods 15. A transmission structure is set between the push-pull rods 15 and the inner wall of the deburring cavity 5.

[0034] The transmission structure includes a fixed plate 19 set on the inner walls of the left and right sides of the deburring chamber 5, a guide plate 22 set on the upper and lower sides of the fixed plate 19, the guide plate 22 is in the shape of a parallelogram, one end of the push-pull rod 15 extends to the fixed plate 19, a fixed ring 17 is fixedly sleeved on the push-pull rod 15, and a spring 20 is sleeved on the push-pull rod 15. The two ends of the spring 20 are respectively connected to the fixed ring 17 and the fixed block 16.

[0035] The deburring structure includes rotating shafts 41 rotatably connected to the inner walls of the left and right sides of the top cover 3. A reciprocating lead screw 42 is connected between the two rotating shafts 41. A lead screw sleeve 43 is fitted onto the reciprocating lead screw 42. Vertical grooves 44 are opened on both sides of the lead screw sleeve 43. A lifting frame 45 is slidably arranged in the vertical grooves 44. A fourth electric push rod 46 is installed in the middle of the bottom of the lead screw sleeve 43. The bottom end of the output shaft of the fourth electric push rod 46 is connected to a bottom frame 47. A second motor 48 is installed in the bottom frame 47. A deburring disc 49 is installed at the bottom end of the output shaft of the second motor 48. A first motor 40 is installed above the right side of the top cover 3. One end of the output shaft of the first motor 40 is connected to one of the rotating shafts 41. First, the fixed frame 8 is started. The central cylinder 9 drives the clamping plate 10 to move, clamping and fixing the sheet metal. Next, the second motor 48 is started, driving the deburring disc 49 to rotate. Then, the first motor 40 and the fourth electric push rod 46 are started. The fourth electric push rod 46 drives the rotating deburring disc 49 to move downwards and fit against the sheet metal. The first motor 40 drives the reciprocating lead screw 42 to rotate, cooperating with the lead screw sleeve 43 to drive the rotating deburring disc 49 to move back and forth along the length of the bracket 1, deburring the sheet metal. Simultaneously, the first electric push rod 21 is started, driving the moving seat 7 and the clamped sheet metal to move to one side. At this time, the push-pull rod 15 on the moving seat 7 is pressed against the guide plate 22. As the plate moves laterally, the spring 20 is in a deformed state. With the movement of the movable seat 7, the plate moves, and the rotating deburring disc 49 can deburr various positions on one side of the plate. After one side of the plate is completely deburred, the first electric push rod 21 continues to move the movable seat 7. The movable seat 7 causes one end of the push-pull rod 15 to disengage from the guide plate 22. Under the elastic force of the deformed spring 20, the push-pull rod 15 returns to its original position on the fixed block 16. The push-pull rod 15 then moves the movable ring 12 on the flipping rod 11. The movable ring 12, in turn, causes the insert rod 13 to press against the wall of the flipping groove 14, pushing the flipping rod 11 to rotate on the movable seat 7, thereby causing the clamping plate 10 to... The clamped plate is flipped and tilted. Then, the first electric push rod 21 drives the moving seat 7 to move in the opposite direction. Under the guidance of the push-pull rod 15, which is tilted at one end of the guide plate 22, the push-pull rod 15 continues to move on the fixed block 16, thereby continuing to drive the insert rod 13 to slide in the flipping groove 14. By using the pressure of one end of the insert rod 13 on the groove wall of the flipping groove 14, the flipping rod 11 is pushed to continue to rotate. In this way, the other side of the plate can be automatically flipped to a horizontal and upward state. Then, the first electric push rod 21 drives the flipped plate to move in the opposite direction. The rotating deburring disc 49 thoroughly deburrs the other side of the plate, thus realizing the deburring processing of both sides of the plate.

[0036] See Figure 1The switching structure includes transverse grooves 24 installed on the inner walls of the front and rear sides of the bracket 1. A moving bar 25 is slidably arranged in the transverse grooves 24. The moving bar 25 is fixedly installed on the switching frame 4. Two second electric push rods 23 are installed on the upper left side of the bracket 1. One end of the output shaft of the second electric push rod 23 is connected to the moving bar 25. When the second electric push rod 23 is started, it drives the switching frame 4 to move back and forth on the bracket 1. It can not only drive the plate to the deburring position for deburring, but also drive another deburred plate to the unloading position for unloading. At the same time, it can also load the plate in time, making full use of the working time and improving the working efficiency.

[0037] See Figure 1 , Figure 4 , Figure 5 and Figure 6 The storage structure includes storage frames 26 set on the left and right sides of the base plate 2. The storage frames 26 have pick-up and drop openings 27 on both the front and back sides. The storage frames 26 have grooves 28 on the upper left and right sides. The storage frames 26 are equipped with a lifting and unloading structure. The lifting and unloading structure includes two sets of fixing bars 18 set on the left and right sides of the storage frame 26. Two vertical rods 30 are connected between the two fixing bars 18 in each set. A lifting plate 31 is movably sleeved on the vertical rod 30. A third electric push rod 29 is installed in the middle below the lower fixing bar 18. A Z-shaped plate 32 is connected in the middle above the lifting plate 31. The Z-shaped plate 32 moves through the upper fixing bar 18. An L-shaped plate 33 moves through the Z-shaped plate 32 near the top. A support plate 34 is installed at the top of the L-shaped plate 33. A driving structure is set between the L-shaped plate 33 and the base plate 2. The shielding and collecting structure includes mounting frames 38 installed at the bottom of the front and rear sides of the top cover 3, and a collecting cover 39 installed between the mounting frames 38. When the switching frame 4 moves the deburred sheet to the unloading position, the cylinder 9 on the fixing frame 8 is activated to detach the clamping plate 10 from the sheet, and the sheet is supported by the corresponding two support plates 34. Then, the third electric push rod 29 on the fixing bar 18 is activated to move the Z-shaped plate 32, the support plate 34 and the deburred sheet as a whole downward. When the Z-shaped plate 32 moves the support plate 34 and the sheet down into the storage frame 26, as the Z-shaped plate 32 continues to move down, it drives one end of the through rod 35 to slide in the driving groove 37 of the vertical plate 36, automatically pulling the two sets of L-shaped plates 33 and the support plate 34 to move synchronously in opposite directions, thereby placing the sheet on the support plate 34 into the storage frame 26 for collection and storage, realizing the automatic unloading function.

[0038] The lifting and unloading structure includes two sets of fixing bars 18 set on the left and right sides of the storage frame 26. Two vertical rods 30 are connected between the two fixing bars 18 in each set. A lifting plate 31 is movably sleeved on the vertical rod 30. A third electric push rod 29 is installed in the middle below the lower fixing bar 18. A Z-shaped plate 32 is connected in the middle above the lifting plate 31. The Z-shaped plate 32 moves through the upper fixing bar 18. An L-shaped plate 33 moves through the Z-shaped plate 32 near the top. A support plate 34 is installed at the top of the L-shaped plate 33. A driving structure is set between the L-shaped plate 33 and the base plate 2.

[0039] The shielding and collecting structure includes mounting frames 38 installed at the bottom of the front and rear sides of the top cover 3, and a collecting cover 39 installed between the mounting frames 38. When the switching frame 4 moves the deburred sheet to the unloading position, the cylinder 9 on the fixing frame 8 is activated to detach the clamping plate 10 from the sheet, and the sheet is supported by the corresponding two support plates 34. Then, the third electric push rod 29 on the fixing bar 18 is activated to move the Z-shaped plate 32, the support plate 34 and the deburred sheet as a whole downward. When the Z-shaped plate 32 moves the support plate 34 and the sheet down into the storage frame 26, as the Z-shaped plate 32 continues to move down, it drives one end of the through rod 35 to slide in the driving groove 37 of the vertical plate 36, automatically pulling the two sets of L-shaped plates 33 and the support plate 34 to move synchronously in opposite directions, thereby placing the sheet on the support plate 34 into the storage frame 26 for collection and storage, realizing the automatic unloading function.

[0040] The implementation principle of a deburring device for sheet metal according to an embodiment of the present invention is as follows: First, the cylinder 9 in the fixed frame 8 is activated to move the clamping plate 10, which clamps and fixes the sheet metal. Next, the second motor 48 is activated to rotate the deburring disc 49. Then, the first motor 40 and the fourth electric push rod 46 are activated. The fourth electric push rod 46 drives the rotating deburring disc 49 to move down and fit against the sheet metal. The first motor 40 drives the reciprocating screw 42 to rotate, which, in conjunction with the screw sleeve 43, drives the rotating deburring disc 49 to move back and forth along the length of the bracket 1 to deburr the sheet metal. At the same time, the first electric push rod 21 is activated to move the moving seat 7 and the clamped sheet metal as a whole to one side. The push-pull rod 15 on the movable seat 7 moves close to one side of the guide plate 22, and the spring 20 is in a deformed state. As the movable seat 7 moves the plate, the rotating deburring disc 49 can deburr various positions on one side of the plate. After one side of the plate is completely deburred, the first electric push rod 21 continues to move the movable seat 7. The movable seat 7 drives one end of the push-pull rod 15 to detach from the guide plate 22. Under the elastic force of the deformed spring 20, the push-pull rod 15 is reset on the fixed block 16. The push-pull rod 15 drives the movable ring 12 to move on the flipping rod 11. The movable ring 12 drives the insertion rod 13 to squeeze the wall of the flipping groove 14, pushing the flipping rod 11 to rotate on the movable seat 7, thereby driving the clamping plate 1. The plates clamped between the zero points are flipped and tilted. Then, the first electric push rod 21 drives the moving seat 7 to move in the opposite direction. Guided by the inclined face of the guide plate 22 at one end, the push rod 15 continues to move on the fixed block 16, thereby continuing to drive the insert rod 13 to slide in the flipping groove 14. By using the pressure of one end of the insert rod 13 against the groove wall of the flipping groove 14, the flipping rod 11 is pushed to continue to rotate. This automatically flips the other side of the plate to a horizontal and upward state. Then, the first electric push rod 21 drives the flipped plate to move in the opposite direction. The rotating deburring disc 49 thoroughly deburrs the other side of the plate. After deburring, the second electric push rod 23 is activated to drive the switching frame 4 to move. The switching frame 4 drives the deburring disc 49 to move. After deburring, the sheet metal is moved to the unloading position. The cylinder 9 on the fixed frame 8 is activated to drive the clamping plate 10 to detach from the sheet metal. The sheet metal is then supported by the two corresponding support plates 34. Next, the third electric push rod 29 on the fixed bar 18 is activated to drive the Z-shaped plate 32, the support plate 34, and the deburred sheet metal as a whole to move down. When the Z-shaped plate 32 drives the support plate 34 and the sheet metal to move down into the storage frame 26, as the Z-shaped plate 32 continues to move down, it drives one end of the through rod 35 to slide in the drive groove 37 of the vertical plate 36, automatically pulling the two sets of L-shaped plates 33 and the support plate 34 to move synchronously in opposite directions, thereby placing the sheet metal on the support plate 34 into the storage frame 26 for collection and storage. This completes the deburring of the sheet metal.

[0041] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
