[0023] See also Figures 1-4 The utility model provides a technical solution: a deburring device for an automobile crankshaft neck, comprising a mounting shell 1 and a deburring mechanism 2, wherein a brush cylinder 6 is arranged inside the mounting shell 1, and a rotating short rod 7 is arranged on one side of the brush cylinder 6; the deburring mechanism 2 is arranged on the mounting shell 1, and the deburring mechanism 2 is used to remove burrs on the outer side and one side port of the crankshaft neck.

[0024] The deburring mechanism 2 includes a dual-axis motor 201, a pulley 202, a rotating rod 203, a belt 204 and a gear 205. The dual-axis motor 201 is fixedly installed on one side of the mounting shell 1, and a rotating rod 203 is rotatably installed inside the mounting shell 1. One end of the rotating rod 203 extends to one side of the mounting shell 1. There are two groups of pulleys 202. A group of pulleys 202 are fixedly installed on the right output shaft of the dual-axis motor 201 and one end of the rotating rod 203, respectively. A belt 204 is sleeved between the two groups of pulleys 202, and the two groups of pulleys 202 are connected by the belt 204. A group of gears 205 are fixedly installed on one end of the rotating short rod 7 and the outer wall of the belt 204, respectively. The two groups of gears 205 are meshed with each other, and the outer side and one side port of the crankshaft neck that needs to be deburred can be cleaned at the same time, thereby shortening the time for deburring the crankshaft neck. The crankshaft neck is deburred by the brush cylinder 6, thereby reducing the damage to the crankshaft neck during deburring, thereby directly improving the work efficiency.

[0025] The left output shaft of the biaxial motor 201 extends into the interior of the mounting housing 1 and is fixedly installed with a first threaded rod 3. The other end of the first threaded rod 3 is rotatably installed on the inner wall of the other side of the mounting housing 1. The outer wall of the first threaded rod 3 is threadedly connected with a movable plate 4. Two sets of mounting holes are provided on the movable plate 4. Two sets of limiting rods 5 are fixedly installed on the inner wall of the mounting housing 1. The limiting rods 5 are slidably installed through the mounting holes and the movable plate 4.

[0026] One side of the movable plate 4 is rotatably installed with a rotating short rod 7. One end of the rotating short rod 7 extends to the other side of the movable plate 4 and is fixedly installed with a brush cylinder 6.

[0027] Two sets of connecting plates 8 are fixedly installed on the other side of the mounting housing 1. A second threaded rod 9 is threadedly connected to the connecting plate 8. One end of the second threaded rod 9 is fixedly installed with the mounting housing 1. The other end of the second threaded rod 9 extends to the bottom of the connecting plate 8 and is fixedly installed with an arc-shaped clamping plate 11. An elastic arc block 12 is fixedly installed at the bottom of the arc-shaped clamping plate 11.

[0028] A circular hole is provided on one side of the mounting housing 1.

[0029] Four sets of supports 13 are fixedly installed at the bottom of the mounting housing 1.

[0030] Working principle: When work is required, the front end of the crankshaft journal to be deburred is placed between the two elastic arc blocks 12. By turning the two second threaded rods 9 through the handle 10, the rotation of the second threaded rods 9 drives the two arc-shaped clamping plates 11 to move towards each other, so that the two elastic arc blocks 12 clamp the crankshaft journal. By controlling the left output shaft of the biaxial motor 201, the left output shaft of the biaxial motor 201 is started to rotate, driving the first threaded rod 3 to rotate. Through the action of the two limiting rods 5, the movable plate 4 moves towards the other side of the mounting housing 1. The movement of the movable plate 4 drives the brush cylinder 6 and a set of gears 205 to move towards the other side of the mounting housing 1. When the brush cylinder 6 moves to the other side of the mounting housing 1 through the circular hole provided on the other side of the mounting housing 1, the brush cylinder 6 can enclose the crankshaft journal to be deburred. At this time, the left output shaft of the biaxial motor 201 is turned off. By controlling the right output shaft of the biaxial motor 201, the right output shaft of the biaxial motor 201 rotates to drive a set of belt pulleys 202 to rotate. Through the action of the belt 204, it drives the other set of belt pulleys 202 to rotate. The rotation of the other set of belt 204 drives the rotating rod 203 to rotate. The rotation of the rotating rod 203 drives the other set of gears 205 to rotate. The two sets of gears 205 are meshed with each other, so that one set of gears 205 rotates. The rotation of one set of gears 205 drives the rotating short rod 7 to rotate. The rotation of the rotating short rod 7 drives the brush cylinder 6 to rotate. The rotation of the brush cylinder 6 can deburr the outer side and one side port of the internal crankshaft journal.
