Description

Technical Field

[0001] The invention relates to the technical field of U-bolt processing, in particular to a horizontal processing center for bolts. Background Art

[0002] U-bolts are U-shaped fasteners with threads at both ends for use with nuts. They are primarily used to secure cylindrical or plate-like structures, such as round pipes and leaf springs. Common materials include carbon steel, alloy steel, and stainless steel. They offer high tensile strength and flexible installation, making them widely used in automotive chassis (for example, securing leaf springs), pipe supports, building steel structures, and mechanical equipment. They come in various shapes, including semicircular, square, and triangular, making them suitable for fastening applications subject to vibration or dynamic loads.

[0003] Existing semi-circular U-shaped bolts have two major problems during the thread processing process: First, the traditional process uses a processing sequence of turning the thread first and then bending it. However, during the bending process, the bending mold easily contacts the processed thread surface, causing scratches on the thread and affecting the subsequent assembly accuracy; second, when the debris generated during the thread processing (including small blocks and clumps of curled debris) is cleaned by the vacuum system, the clumps of curled debris are very likely to clog the bends or joints of the vacuum duct, seriously affecting the continuous cleaning effect of the vacuum system.

First, according to the rotation axis of the fixed ring 4, the first threaded rod 22 is rotated appropriately to drive the lifting seat 23 and its mounted tool holder 24 and turning tool 25 to move up and down to a suitable height. Then, according to the width of the U-bolt 38, the third telescopic cylinder 33 is activated, and the third telescopic cylinder 33 drives the moving frame 34 to move to a suitable position from the rotation axis of the fixed ring 4. Then, the two ends of the U-shaped bolt 38 are respectively inserted into the middle of the fixing ring 4 and the middle of the two clamping members 8, and the three second telescopic cylinders 30 are started. The three second telescopic cylinders 30 drive the three fixed blocks 6 to fix one end of the U-shaped bolt 38. At the same time, the first two-way threaded rod 35 and the second threaded rod 36 are rotated in sequence so that the two clamping members 8 and the first lower pressure plate 40 and the second lower pressure plate 39 fix the other end of the U-shaped bolt 38. After that, the first telescopic cylinder 29 is started. The first telescopic cylinder 29 drives the fixing ring 4 and the mechanism installed on the fixing ring 4 and the U-shaped bolt 38 to move backward until the rear end of the U-shaped bolt 38 is fitted into the slot 7 opened on the right side of the T-shaped support plate 5. The driving motor 27 and the turning mechanism are started. The driving motor 27 drives the U-shaped bolt 38 to rotate with one end as the axis. At the same time, the turning mechanism drives the turning tool 25 to perform outer thread turning processing on one end of the U-shaped bolt 38.

[0023] The front side of the fixed ring 4 is rotatably connected to a dust suction and crushing mechanism, which includes a V-shaped dust suction box 9, and a crushing cylinder 10 is fixedly connected to the bottom end of the V-shaped dust suction box 9. Two groups of mutually staggered tearing rods 11 are provided on the inner side of the crushing cylinder 10 and near the upper end. Three tearing blades 12 are fixedly installed on the outer surface of the tearing rod 11. The cutting edge of the tearing blade 12 is set to be serrated. The dust suction and crushing mechanism also includes a connecting ring 41, a fixed rod 45, a second bidirectional threaded rod 44 and two movable rods 46. The left side of the connecting ring 41 is rotatably matched with the right end of the fixed ring 4, and the outer surface of the connecting ring 41 is fixedly connected to the upper end of the V-shaped dust suction box 9 near the bottom end. A connecting frame 42 is fixedly installed on the outer surface of the connecting ring 41 near the front side, and a movable end of a third guide rod 43 is fixedly connected to the front side of the connecting frame 42. The left end of the third guide rod 43 is fixedly installed on the right side of the fixed side plate 3 through a mounting piece. The second two-way threaded rod 44 and the fixed rod 45 are respectively arranged on the inner side of the crushing cylinder 10 near the left and right ends. The two ends of the fixed rod 45 are fixedly connected to the inner side of the crushing cylinder 10, and the two ends of the second two-way threaded rod 44 are rotatably connected to the inner side of the crushing cylinder 10. The bottom ends of the two groups of tearing rods 11 are fixedly installed on the upper sides of the two moving rods 46, and the right ends of the two moving rods 46 are slidably matched with the outer surface of the fixed rod 45. The left and right ends of the moving rod 46 are rotatably connected to two moving blocks 54 respectively, the right end of the moving rod 46 is fixedly connected to the third motor 53, the upper side of the third motor 53 is fixedly installed on the right side of the right moving block 54 through a mounting piece, the inner upper ends of the two right moving blocks 54 are slidably matched with the outer surface of the fixed rod 45, and the inner upper ends of the two left moving blocks 54 are threadedly matched with the outer surface of the second bidirectional threaded rod 44, the rear end of the second bidirectional threaded rod 44 passes through the rear side of the crushing cylinder 10 and is fixedly connected to the output shaft of the first motor 47, the first motor 47 The right side is fixedly mounted on the outside of the crushing cylinder 10 through a connecting piece, the bottom end of the crushing cylinder 10 is rotatably mounted with a drive shaft 48, the upper end of the drive shaft 48 is fixedly connected to a crushing blade 49, the bottom end of the drive shaft 48 is fixedly connected to a second motor 50, the outer side of the second motor 50 is fixedly mounted on the bottom end of the crushing cylinder 10 through a connecting piece, the right side of the crushing cylinder 10 and near the bottom end is fixedly connected to the bottom end of a hose 51, a filter is fixedly mounted at the dust suction port at the bottom end of the hose 51, and the upper end of the hose 51 is fixedly mounted on the right side of the connecting frame 42 through a fixing piece; The started vacuum cleaner generates a suction airflow through the telescopic suction pipe and the hose 51, which reaches the processing position through the crushing cylinder 10 and the V-shaped dust box 9, and sucks the generated small block debris and ball-shaped curled debris into the crushing cylinder 10. At the same time, the first motor 47 is synchronously started with the second motor 50 and the two third motors 53. The first motor 47 drives the second bidirectional threaded rod 44 to rotate, so that the two sets of staggered tearing rods 11 are separated from each other. At the same time, the two third motors 53 respectively drive the moving rod 46 and the two sets of tearing rods 11 above it to rotate outward, so that the tearing rods 11 are separated from each other. The crushing blades 12 perform preliminary tearing of the clumping curled debris, breaking it down into short strips or loose fragments. Subsequently, the two third motors 53 reverse, driving the two sets of tearing rods 11 to rotate inward. At this time, the clumping curled debris that has undergone preliminary tearing falls downward under the action of gravity, and the crushing blades 49 driven by the second motor 50 below perform secondary crushing. Finally, the crushed debris is smoothly sucked away through the hose 51. The above operation effectively prevents the clumping curled debris from directly entering the vacuum suction pipe, thereby preventing the problem of blockage at the bends and joints of the pipe.

[0024] During use, the first threaded rod 22 is rotated appropriately according to the rotation axis of the fixed ring 4, driving the lifting seat 23 and its mounted tool holder 24 and turning tool 25 to move up and down to a suitable height. Then, according to the width of the U-shaped bolt 38, the third telescopic cylinder 33 is activated. The third telescopic cylinder 33 drives the moving frame 34 to move to a suitable position from the rotation axis of the fixed ring 4. Then, the upper end of the hose 51 is connected to the telescopic suction pipe. Then, the two ends of the U-shaped bolt 38 are respectively inserted into the middle of the fixing ring 4 and the middle of the two clamping members 8, and the three second telescopic cylinders 30 are started. The three second telescopic cylinders 30 drive the three fixing blocks 6 to fix one end of the U-shaped bolt 38. At the same time, the first two-way threaded rod 35 and the second threaded rod 36 are rotated in sequence, so that the two clamping members 8 and the first lower pressure plate 40 and the second lower pressure plate 39 fix the other end of the U-shaped bolt 38. After that, the first telescopic cylinder 29 is started. The first telescopic cylinder 29 drives the fixing ring 4 and the mechanism installed on the fixing ring 4 and the U-shaped bolt 38 to move backward until the rear end of the U-shaped bolt 38 is abutted against the card slot 7 opened on the right side of the T-shaped support plate 5. The driving motor 27 and the turning mechanism are started. The driving motor 27 drives the U-shaped bolt 38 to rotate with one end as the axis. At the same time, the turning mechanism drives the turning tool 25 to perform outer thread turning processing operation on one end of the U-shaped bolt 38. The synchronously started vacuum cleaner generates a suction airflow through the telescopic vacuum tube and the hose 51, which reaches the processing position through the crushing cylinder 10 and the V-shaped dust box 9, and sucks the generated small block debris and clumping curled debris into the crushing cylinder 10. At the same time, the first motor 47 is synchronously started with the second motor 50 and the two third motors 53. The first motor 47 drives the second bidirectional threaded rod 44 to rotate, so that the two sets of staggered tearing rods 11 are moved away from each other. At the same time, the two third motors 53 respectively drive the moving rod 46 and the two sets of tearing rods 11 above it to rotate outward, so that the tearing blade 12 can initially tear the clumping curled debris into pieces, breaking it into short strips or loose fragments, thereby effectively preventing the clumping debris from directly entering the area of ​​the crushing blade 49 below and causing possible damage to the crushing blade 49.

[0025] Subsequently, the two third motors 53 rotate inversely, driving the two sets of shredding rods 11 to rotate inward. At this time, the clumping and curled debris that have undergone the initial shredding process falls downward under the action of gravity. The crushing blades 49 driven by the second motor 50 below perform secondary crushing. Finally, the crushed debris is smoothly sucked away through the hose 51. The above operation effectively prevents the clumping and curled debris from directly entering the dust collection duct, thereby preventing the problem of blockage at the bends and joints of the duct. After the thread processing of one end of the U-shaped bolt 38 is completed, it is removed from the rotating fixing mechanism, and the U-shaped bolt 38 is turned 180 degrees. The above operation is repeated to perform thread processing on the other end of the U-shaped bolt 38.
