Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] As Figures 1 to 7 shown, the utility model provides a double - headed angle saw for bumper processing, including a bracket 1. A bottom frame 2 is fixedly installed at the top of the bracket 1. An operating table 3 is movably installed at the top of the bottom frame 2. First motors 4 are respectively and fixedly installed on the left and right sides at the bottom end of the operating table 3. The other end of the output shaft of the first motor 4 is fixedly sleeved with a rotating shaft 5. The top end of the rotating shaft 5 penetrates through the operating table 3 and extends to the outside of the operating table 3 and is fixedly installed with a turntable 6. A fixed block 7 is fixedly installed in the middle of the top end of the turntable 6. An activity plate 8 is movably sleeved on the outer surface of the fixed block 7. A first lead screw 9 is movably sleeved in the fixed block 7. A first movable block 10 located inside the fixed block 7 is threadedly sleeved on the outer surface of the first lead screw 9. The top end of the first movable block 10 is fixedly connected to the middle of the bottom end of the activity plate 8. A support block 11 is fixedly installed on the left side of the top end of the activity plate 8. A second motor 12 is fixedly installed on the left side at the rear end of the activity plate 8. The other end of the output shaft of the second motor 12 is fixedly sleeved with a second lead screw 13. The other end of the second lead screw 13 penetrates through the support block 11 and extends to the outside of the support block 11. A second movable block 14 located inside the support block 11 is threadedly sleeved on the rear side of the outer surface of the second lead screw 13. A square plate 15 is fixedly installed at the top end of the second movable block 14.
[0025] When the first motor 4 is started, the rotating shaft 5 will drive the turntable 6 to rotate. When the first lead screw 9 is rotated, the first movable block 10 threadedly sleeved with the first lead screw 9 will drive the activity plate 8 to move along the inner surface of the fixed block 7. When the second motor 12 is started, the second lead screw 13 will rotate. At this time, the second movable block 14 threadedly sleeved with the second lead screw 13 will drive the square plate 15 to move along the inner surface of the support block 11. With the mutual cooperation of the first motor 4, the first lead screw 9 and the second motor 12, the adjustment of the rotation angle of the double - headed angle saw and the adjustment of the distance between the two heads of the double - headed angle saw are realized, so that the double - headed angle saw can process bumpers of different lengths, and further makes the double - headed angle saw suitable for the cutting treatment of various bumpers.
[0026] Among them, a placement table 16 is fixedly installed on the right side of the top end of the activity plate 8. Baffles 17 are respectively and fixedly installed on the left and right sides at the rear end of the placement table 16.
[0027] The existence of the baffle 17 will play an auxiliary role in fixing the bumper.
[0028] Among them, a pneumatic cylinder 18 is fixedly installed at the front part on the left side of the top end of the placement table 16. A clamping block 19 is fixedly installed at the rear end of the pneumatic cylinder 18.
[0029] When the pneumatic cylinder 18 is started, it will push the clamping block 19, so that the clamping block 19 cooperates with the baffle 17 to clamp and fix the bumper.
[0030] Among them, a driving motor 20 is fixedly installed at the rear end of the square plate 15. The other end of the output shaft of the driving motor 20 is fixedly sleeved with a driving shaft 21. The right side of the outer surface of the driving shaft 21 is fixedly sleeved with a saw blade 22.
[0031] After the driving motor 20 is started, the driving shaft 21 will drive the saw blade 22 to rotate, thereby cutting the bumper.
[0032] Among them, the left and right sides of the bottom end of the operating table 3 are respectively hinged with inclined rods 23. The other ends of the inclined rods 23 are hinged with rectangular blocks 24. The number of rectangular blocks 24 is two and they are symmetric about the center of the operating table 3 respectively.
[0033] When the rectangular block 24 drives the inclined rod 23 to move, the other end of the inclined rod 23 will generate a thrust on the operating table 3, pushing the operating table 3 to move upward.
[0034] Among them, a power motor 25 is fixedly installed at the bottom of the left end of the bracket 1. The other end of the output shaft of the power motor 25 is fixedly sleeved with a double threaded rod 26. The right end of the double threaded rod 26 passes through the bracket 1 and the rectangular block 24 and extends to the outside of the bracket 1. The left and right sides of the outer surface of the double threaded rod 26 are respectively threadedly sleeved with the inner surfaces of the two rectangular blocks 24.
[0035] After the power motor 25 is started, the double threaded rod 26 will rotate, so that the two rectangular blocks 24 threadedly sleeved with the double threaded rod 26 move towards each other.
[0036] Among them, a limiting rod 27 is fixedly sleeved at the bottom end inside the bracket 1. The outer surface of the limiting rod 27 is movably sleeved with the inner surface of the rectangular block 24. The bottom parts inside the left and right ends of the bracket 1 are respectively movably installed with limiting plates 28. The top ends of the limiting plates 28 pass through the bracket 1 and the bottom frame 2 and extend to the outside of the bottom frame 2 and are fixedly connected to the bottom end of the operating table 3.
[0037] Due to the existence of the limiting rod 27, the movement of the rectangular block 24 will be restricted, while the limiting plate 28 can restrict the movement of the operating table 3.
[0038] The working principle and usage process of the present utility model:
[0039] First, the operator rotates the first lead screw 9 according to the length of the bumper to be processed, so that the first movable block 10 threadedly sleeved with the first lead screw 9 drives the movable plate 8 to move along the inner surface of the fixed block 7 until the distance between the double-headed angle saws is adapted to the length of the bumper. Subsequently, the operator starts the first motor 4 according to the curvature at both ends of the bumper to be processed, so that the rotating shaft 5 drives the turntable 6 to rotate until the rotation angle of the turntable 6 is adapted to the curvature of the bumper. Then, the operator presses the bumper against the baffle 17 and places it on the top of the placing table 16, and then starts the air cylinder 18, so that the clamping block 19 cooperates with the baffle 17 to clamp and fix the bumper. Subsequently, the operator starts the driving motor 20, so that the driving shaft 21 drives the saw blade 22 to rotate. Immediately afterwards, the operator starts the second motor 12, so that the second lead screw 13 rotates, thereby causing the second movable block 14 to drive the square plate 15 to move under the action of the second lead screw 13, and further causing the driving motor 20 and the saw blade 22 to move together to complete the cutting operation of the bumper. With the mutual cooperation of each mechanism, the processing of bumpers with different lengths is realized, so that the double-headed angle saw can be applicable to various bumpers, and thus the practicability of the double-headed angle saw is improved.
[0040] When the double-headed angle saw is used by operators of different heights, the operator starts the power motor 25, so that the double threaded rod 26 rotates. At this time, the two rectangular blocks 24 threadedly sleeved with the double threaded rod 26 will respectively drive the bottom ends of the inclined rods 23 to move towards each other along the outer surface of the limiting rod 27, and further cause the other end of the inclined rod 23 to generate a thrust on the bottom end of the operating table 3, pushing the operating table 3 with the limiting plate 28 to move upward until the height of the operating table 3 is adapted to the height of the operator, so as to facilitate the use of operators of different heights, and thus improve the convenience of the double-headed angle saw during use.
