DETAILED DESCRIPTION

[0014] Clearly, the described embodiments are merely part of the embodiments of the present application, but not all the embodiments.

[0015] Please refer to Figures 1 to 5 The embodiment provides a deburring mechanism of an automobile sheet metal stamping die, which comprises a rack 1, a supporting plate 2 fixed to the middle part of one side of the top surface of the rack 1, the upper end of the supporting plate 2 horizontally extending to one side of the rack 1 to form an installation part 3, a through groove 4 formed in the middle part of the supporting plate 2 along the length direction of the supporting plate 2, two reinforcing ribs 5 symmetrically fixed to the top of the rack 1, and the two reinforcing ribs 5 are fixed to the outer wall of the supporting plate 2 to improve the connection strength of the supporting plate 2.

[0016] A motor 6 is fixed to the middle part of one end of the installation part 3 away from the rack 1, the motor 6 is a worm gear deceleration motor, the motor 6 is arranged in a longitudinal direction, the output end of the motor 6 extends to the lower part of the installation part 3 through the through groove 4, and the bottom surface of the installation part 3 is fixed with a driving disc 7. The axis of the driving disc 7 coincides with the axis of the output end of the motor 6, and the axis of the driving disc 7 is rotatably connected with a rotating shaft 8 through a bearing, a reinforcing ring 9 is fixed to the center of the top surface of the driving disc 7, and the rotating shaft 8 is rotatably inserted into the reinforcing ring 9, thereby improving the stability of the rotating shaft 8.

[0017] The upper end of the rotating shaft 8 is fixed with the output end of the motor 6 through a shaft coupling, the lower end of the rotating shaft 8 is fixed with a sliding rod 10, the sliding rod 10 is arranged in a transverse direction, the axis of the sliding rod 10 is perpendicular to the axis of the rotating shaft 8, the outer wall of the sliding rod 10 is provided with a limiting groove 11, the length direction of the limiting groove 11 is parallel to the axis of the sliding rod 10, the motor 6 is driven to work, the rotating shaft 8 is driven to rotate, and the sliding rod 10 is driven to rotate around the axis of the driving disc 7.

[0018] The outer side of the sliding rod 10 is slidably sleeved with a sliding sleeve 12, the inner wall of the sliding sleeve 12 is formed with a limiting strip 13, the limiting strip 13 is slidably inserted into the inner wall of the limiting groove 11, so that the sliding sleeve 12 can slide along the length axis of the sliding rod 10, but the sliding sleeve 12 and the sliding rod 10 cannot rotate relative to each other.

[0019] The mounting plate 14 is horizontally arranged and located at the lower part of the sliding sleeve 12, and the mounting plate 14 is integrally arranged with the sliding sleeve 12, the polishing machine 15 is fixed on the bottom surface of the mounting plate 14, and the outer wall of the sliding sleeve 12 is also rotatably connected with the driving shaft 16 arranged longitudinally through a bearing, the driving shaft 16 is located at the upper part of the sliding sleeve 12, and the rotation axis of the polishing head of the polishing machine 15 coincides with the axis of the driving shaft 16, and the bottom surface of the driving disc 7 is provided with the driving groove 17 surrounding the rotating shaft 8, the driving groove 17 is composed of two parts, which are the arc-shaped groove 18 arranged around the rotating shaft 8 and the straight groove 19 communicated with the two ends of the arc-shaped groove 18, respectively, and the corner between the inner wall of the straight groove 19 and the inner wall of the arc-shaped groove 18 is smoothly transitioned in a circular arc shape, and the upper end of the driving shaft 16 is inserted into the driving groove 17, the arc-shaped groove 18 is located at the side close to the rack 1, the straight groove 19 is located at the side away from the rack 1, and the extension direction of the straight groove 19 is parallel to the length direction of the rack 1.

[0020] Thus, by the working of the driving motor 6, the rotating shaft 8 is driven to rotate, so that the sliding rod 10 is rotated, and the sliding sleeve 12 is synchronously rotated around the axis of the driving disc 7 in the process of the rotation of the sliding rod 10, but due to the cooperation of the driving groove 17 and the driving shaft 16, the sliding sleeve 12 also slides with the sliding rod 10, specifically, when the driving shaft 16 enters the arc-shaped groove 18, the sliding rod 10 rotates around the axis of the driving disc 7, and the sliding sleeve 12 does not displace with the sliding rod 10, when the driving shaft 16 enters the straight groove 19, the sliding rod 10 rotates around the axis of the driving disc 7, and then the sliding sleeve 12 slides with the sliding rod 10, but due to the action of the straight groove 19, the driving shaft 16 moves along a moving track parallel to the length direction of the rack 1, and similarly, the polishing head of the polishing machine 15 also moves along the moving track.

[0021] Thus, when the surface of the mold on the conveying line is deburred and polished, the mold conveying path is ensured to coincide with the movement track, when the mold is conveyed to the starting end of the movement track, the slide rod 10 is driven to rotate around the driving disc 7, so that the polishing head of the polisher 15 is just above the mold, then the polisher 15 is driven to work, and the polishing work is carried out, while the mold is conveyed, the motor 6 rotates, so that the driving shaft 16 matches the mold movement speed, moves in the flat groove 19 together with the mold, in the process of synchronous movement, the polisher 15 realizes the follow-up synchronous polishing operation of the mold, until the driving shaft 16 reaches the end of the movement track, the polishing work is completed, then the motor 6 continues to drive the slide rod 10 to rotate, after that the driving shaft 16 enters the arc-shaped groove 18, until the driving shaft 16 enters the starting end of the movement track again, and at this time the next mold is just below the polishing head, and the deburring and polishing work of the next mold is continued, so the cycle is repeated, the synchronous polishing work during the mold transportation can be realized, the mold does not need to be stationary, and the polishing efficiency is greatly improved.

[0022] It needs to be emphasized that the polishing head of the polisher 15 adopts a blade type polishing disc, since the surface of the polishing disc is equidistantly arranged with multiple inclined polishing papers, so the polishing surface of the polishing head has a deformation ability, that is, when the mold coincides with the position of the polishing head of the polisher 15 during the conveying process, the polishing head will be deformed to abut against the surface of the mold, so as to avoid the situation that the positions of the mold and the polishing head coincide but there is no contact part.

[0023] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
