Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision beam processing, in particular to an automobile anti-collision beam cutting machine. Background Art

[0002] The anti-collision beam is a device used to reduce the impact energy of the vehicle when it is hit by a collision. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage of the impact force to the longitudinal beam of the vehicle body, thereby playing a protective role for the vehicle.

[0003] After searching, Chinese patent CN114799336A was found and announced, which is a cutting device for trimming automobile anti-collision beams. During cutting, the automatic anti-collision beam can be fixed by two clamping plates, avoiding the time-consuming and labor-intensive problem of manually fixing the anti-collision beam. After cutting, the fixation of the anti-collision beam can be automatically released, which is easy to use. It can be seen that this patent realizes the fixation and cutting of the anti-collision beam. During cutting, the rotation of the first threaded rod is used to drive the cutting knife to move for cutting. However, the method of driving the cutting knife to move only requires adjusting the rotation of the first threaded rod during cutting, and does not intermittently control the movement of the cutting knife, resulting in the need to control the rotation of the first threaded rod every time, thereby affecting the cutting efficiency of the automobile anti-collision beam. For this reason, an automobile anti-collision beam cutting machine is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3 A car anti-collision beam cutting machine includes a workbench 1, with support frames 2 fixedly installed on both sides of the top of the workbench 1. The support frames 2 are L-shaped, and a mounting shell 3 is fixedly installed between the opposite sides of the support frames 2 on both sides. A vertical rod 4 is fixedly installed between the opposite sides of the inner top wall and the inner bottom wall of the mounting shell 3.

[0021] See also Figure 1-3 A baffle 7 is fixedly installed on the top of the workbench 1 and behind the support frame 2. The car anti-collision beam is placed on the workbench 1 and against the baffle 7, so that the rear position of the car anti-collision beam can be positioned. A mounting frame 8 is fixedly installed on the side wall of the workbench 1. The shape of the mounting frame 8 is 匚-shaped. A clamping assembly 9 is provided on the workbench 1 and the mounting frame 8. The clamping assembly 9 includes a servo motor 91, a bidirectional threaded rod 92, a connecting frame 93 and a clamping plate 94. The servo motor 91 is fixedly mounted on the side wall of the mounting frame 8, and the bidirectional threaded rod 92 is fixedly mounted on the output shaft of the servo motor 91. The bidirectional threaded rod 92 is rotatably connected to the workbench 1. The bidirectional threaded rod 92 is rotatably connected to the mounting frame 8, and the bidirectional threaded rod 92 can be supported.

[0022] In addition, a limit block 10 is fixedly installed at one end of the two-way threaded rod 92 to prevent the connecting frame 93 from detaching from the outer surface of the two-way threaded rod 92, thereby playing a limiting role. The connecting frame 93 is threadedly connected to the outer surface of the two-way threaded rod 92, and the connecting frame 93 is threadedly connected to the positive and negative threads on the outer surface of the two-way threaded rod 92, so that the connecting frames 93 on both sides move closer to each other or move away from each other, move closer to each other to clamp the two ends of the automobile anti-collision beam, and move away from each other to release the automobile anti-collision beam after cutting. The connecting frame 93 is slidably connected to the support frame 2, which limits the freedom of rotation of the connecting frame 93, so that the connecting frame 93 can only move and will not rotate. The clamping plate 94 is fixedly installed on the opposite side of the connecting frames 93 on both sides, which can drive the clamping plate 94 to clamp the two ends of the automobile anti-collision beam.

[0023] See also Figure 1-3 , the mounting shell 3 and the vertical rod 4 are provided with an interval cutting component 5 for cutting the edges and corners of the automobile anti-collision beam. The interval cutting component 5 includes a reduction motor 51, a crankshaft 52, a movable plate 53, a driving hole 54 and a cutting knife 55. The reduction motor 51 is fixedly mounted on the front wall of the mounting shell 3, and the crankshaft 52 is fixedly mounted on the output shaft of the reduction motor 51. The crankshaft 52 is rotatably connected to the mounting shell 3. When the reduction motor 51 is started, the crankshaft 52 rotates, and the automobile anti-collision beam is gradually cut at intervals. The movable plate 53 is slidably connected to the outer surface of the vertical rod 4, and the movable plate 53 slides up and down on the outer surface of the vertical rod 4. The bottom of the movable plate 53 is fixedly connected to a mounting column 6 that is slidably connected to the bottom wall of the mounting shell 3.

[0024] In addition, the driving hole 54 is opened on the movable plate 53 and can move up and down with the movable plate 53. The shape of the driving hole 54 is half a circle, and the opening direction of the driving hole 54 is downward. The crankshaft 52 extends into the driving hole 54 and is movably connected with the driving hole 54. When the rotating crankshaft 52 moves to the same half-circular trajectory as the driving hole 54, the movable plate 53 does not move. When the rotating crankshaft 52 moves to a half-circular trajectory different from the driving hole 54, it pushes the movable plate 53 to move downward and then lift it, thereby realizing the spaced cutting of the corners of the automobile anti-collision beam. The cutting knife 55 is set at the bottom of the movable plate 53, and the cutting knife 55 is fixedly mounted at the bottom of the mounting column 6 for cutting the corners of the automobile anti-collision beam.

[0025] When this embodiment is in use, the automobile anti-collision beam is placed on the workbench 1 and against the baffle 7, the servo motor 91 is started, the bidirectional threaded rod 92 rotates, driving the connecting frame 93 and the clamping plate 94 to move, and the clamping plates 94 on both sides clamp the two ends of the automobile anti-collision beam, the reduction motor 51 is started, the crankshaft 52 rotates, and when the crankshaft 52 rotates to the same trajectory as the drive hole 54, the cutting knife 55 moves up. At this time, the automobile anti-collision beam is placed and the two ends of the automobile anti-collision beam are clamped. When the crankshaft 52 rotates to the opposite trajectory of the drive hole 54, the crankshaft 52 pushes the cutting knife 55 to move down to cut the edges and corners of the automobile anti-collision beam.

[0026] The beneficial effects of the above embodiment are:

[0027] The automobile anti-collision beam cutting machine is provided with an interval cutting component 5. After the interval cutting component 5 is used, when the crankshaft 52 rotates to coincide with the trajectory of the driving hole 54 of a half circle, the movable plate 53 and the cutting knife 55 do not move. When the crankshaft 52 rotates to the opposite trajectory of the driving hole 54 of the half circle, the cutting knife 55 is pushed to move downward and then upward, so that the cutting knife 55 can cut the corners of the automobile anti-collision beam. Since the movable plate 53 and the cutting knife 55 do not move during this period, the automobile anti-collision beam can be placed and clamped, and then the corner cutting work can be carried out, which basically ensures the continuous placement, clamping and cutting work, and does not require additional pauses, thereby improving the cutting efficiency of the automobile anti-collision beam.

[0028] The reduction motor 51 and servo motor 91 appearing in the article are both electrically connected to the main controller and the power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing disclosed power connection technology is not described in detail in the article.
