[0021] Example 1

[0022] like Figures 1-4 As shown, a rubber oil seal trimming device proposed in this embodiment includes a frame 1, a transmission belt 2 and a plurality of automatic trimming devices.

[0023] The transmission belt 2 is installed on the frame 1, and a power component for driving the transmission belt 2 to move is installed on the frame 1. The power component includes a servo motor 41, two transmission shafts 42, two synchronous belts 44 and four synchronous pulleys 43. The two transmission shafts 42 are rotatably installed at both ends of the frame 1. The servo motor 41 is installed on the frame 1 and its output shaft is connected to the transmission shaft 42 on one side. The four synchronous pulleys 43 are respectively installed at both ends of the transmission shaft 42 on both sides. The two synchronous pulleys 43 on the same side are connected by a synchronous belt 44, and the transmission belt 2 is fixed to the outer periphery of the two synchronous belts 44.

[0024] A support rod 8 is provided at the inner upper end of the transmission belt 2, and the support rod 8 is connected to the frame 1. The support rod 8 can prevent the middle part of the upper end of the transmission belt 2 from falling.

[0025] A plurality of automatic trimming devices are installed on the transmission belt 2, and the automatic trimming device includes a rotating seat 3 and a cutting mechanism; an annular limiting groove 301 is provided on the rotating seat 3, and a support plate 9 is provided at the bottom end of the rotating seat 3, and the support plate 9 is installed on the outer surface of the transmission belt 2, and a rotating sleeve 20 is connected to the rotating seat 3, and the rotating sleeve 20 is rotatably set on the support plate 9 and is installed with a gear ring 21, and the rotating sleeve 20 movably passes through the transmission belt 2, and a rack 7 is provided on the inner side of the transmission belt 2, and the rack 7 is connected to the frame 1; the cutting mechanism includes a cutter mounting plate 11 and a plurality of cutters 12 mounted on the cutter mounting plate 11. It should be added that the cutter 12 is connected to the cutter mounting plate 11 by screws, and A plurality of screw holes are provided on the cutter mounting plate 11, which can be used to adjust the installation position of the cutter 12 to adapt to the trimming of rubber oil seals of different diameters. A bracket 10 is connected to the support plate 9, and an elastic reset assembly is connected between the cutter mounting plate 11 and the bracket 10. The elastic reset assembly includes a first guide rod 14, a first spring 15 and a limit plate 13. The first guide rod 14 movably passes through the bracket 10. The two ends of the first guide rod 14 are respectively connected to the cutter mounting plate 11 and the limit plate 13. The first spring 15 is sleeved and installed on the first guide rod 14. A first guide plate 5 is provided above the transmission belt 2. The first guide plate 5 is connected to the frame 1, and one end of the first guide plate 5 is an upwardly bent structure.

[0026] A plurality of anti-touch plates 22 are provided above the transmission belt 2, and the anti-touch plates 22 are connected to the frame 1. A plurality of cutters 12 adjacent to the starting end of the transmission belt 2 are located above the anti-touch plates 22. This arrangement can prevent the operator from accidentally touching the cutter 12 when placing the workpiece, thereby ensuring the safety of the operation.

[0027] Specifically, the power component drives the transmission belt 2 to move, and the transmission belt 2 then drives multiple automatic trimming devices to move along the path direction of the transmission belt 2. During this process, the workpiece (rubber oil seal) is placed on the rotating seat 3, so that the rubber oil seal is stuck on the inner side of the annular limit groove 301. As the automatic trimming device moves, when the limit plate 13 contacts the bent part of the first guide plate 5, the limit plate 13 is forced to move downward gradually, that is, the cutter mounting plate 11 and the cutter 12 are driven to move downward. At this time, multiple cutters 12 are respectively in contact with the parts of the workpiece edge that need to be trimmed. When the gear ring 21 contacts the rack 7, as the transmission belt 2 moves, the gear ring 21 starts to rotate, that is, it drives the rotating seat 3 to rotate, and the rotating seat 3 drives The workpiece rotates, and the excess parts of the inner and outer edges of the workpiece are cut off during the rotation. When the workpiece moves to the conveying end position of the transmission belt 2, the limit plate 13 is separated from the first guide plate 5, and the cutter 12 is reset upward under the elastic force of the first spring 15, and the gear ring 21 is also separated from the rack 7 at this time, and the workpiece stops rotating. When the workpiece starts to rotate downward, the workpiece and the residual material fall off the rotating seat 3. The operator can set a barrel for receiving the workpiece under the conveying end of the transmission belt 2. Furthermore, in order to prevent the workpiece from being stuck on the cutter 12 due to the close distance between the workpiece and the cutter 12 during the unloading process, the distance between the cutter 12 and the rotating seat 3 needs to be set larger than the diameter of the workpiece.

[0028] To sum up, the present technical solution has at least three workstations of material discharge, cutting and unloading, and the above steps can be carried out simultaneously, thereby improving production efficiency. In addition, the technical solution drives the transmission belt 2 through the power component to realize the automatic downward movement of the cutter 12 and the automatic rotation drive of the workpiece during the movement, thereby realizing automatic trimming of the workpiece without the need to add other driving equipment, thereby saving the manufacturing cost of the equipment.
