DETAILED DESCRIPTION

[0021] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 7 , the present invention provides a technical solution: A rubber seal trimming device includes a blade 12, which is installed on a frame 1, and also includes a feeding frame 3 clamped on the top of the frame 1, a bearing shaft 9 is located at the bottom of the feeding frame 3, a base 15 is rotatably connected to the fixing ring 5, a guide rod 21 is installed on the base 15, the guide rod 21 is sleeved with the bearing shaft 9, the diameter of the bearing shaft 9 is the same as the inner diameter of the rubber seal, the rubber seal is a circular ring structure, a collecting frame 4 is placed on the side of the frame 1, and a feeding port 2 with the same outer diameter as the rubber seal is opened on the feeding frame 3, and the depth of the feeding port 2 is the same as the height of the feeding frame 3.

[0023] Put the sealing ring into the feeding port 2, the sealing ring falls downward through the feeding port 2, and the sealing ring is sleeved on the load-bearing shaft 9. The limiting plate 13 limits the lowest sealing ring until the sealing rings are accumulated and the top is flush with the bottom of the feeding port 2. After that, the sealing ring will not fall downward any more, realizing automatic feeding. The inner ring of the sealing ring fits with the outer side of the load-bearing shaft 9, and the position of the conditional blade 12 is used to align the outer side of the sealing ring with the trimming side of the blade 12.

[0024] An automatic unloading mechanism is installed on the frame 1. The automatic unloading mechanism rotates the rubber seal to a downward state through the fixing ring 5 to automatically realize unloading. The fixing ring 5 is located on both sides of the inside of the frame 1. The automatic unloading mechanism includes a fixing ring 5, a base 15 and a connecting rod 18. The frame 1 is rotatably connected to a rotating rod 7, and the connecting rod 18 is installed on the rotating rod 7. The other end of the connecting rod 18 is installed with a fixing ring 5. The connecting column 6 installed on the fixing ring 5 is connected to a baffle 11. The center of the baffle 11 is on the straight line extended from the center of the two fixing rings 5. The top of the baffle 11 fits with the outer side of the rubber seal, and the top of the load-bearing shaft 9 is flush with the top of the baffle 11.

[0025] After the trimming of the sealing ring on the load-bearing shaft 9 is completed, the rotating rod 7 is rotated by hand. During the rotation of the rotating rod 7, the connecting rod 18 is driven to rotate synchronously. During the rotation of the connecting rod 18, the fixing ring 5 is driven to rotate synchronously. The fixing ring 5 rotates the base 15 to rotate synchronously. The rotation of the base 15 drives the guide rod 21 to rotate synchronously to the side. During the rotation of the guide rod 21, the limit plate 13 and the load-bearing shaft 9 are driven to rotate synchronously. During the rotation of the fixing ring 5, the baffle rod 11 is driven to rotate synchronously. The baffle rod 11 rotates to the side. During the rotation of the baffle rod 11, the outer side is fitted with the bottom of the loading port 2, and the baffle rod 11 is used for loading. The sealing ring placed inside the opening 2 is limited to prevent the sealing ring inside the loading opening 2 from falling downward when the bearing shaft 9 rotates to the side. After the bearing shaft 9 rotates to the downward position, the sealing ring on the bearing shaft 9 slides into the inside of the collecting frame 4 to collect the sealing ring. During the rotation, the base 15 drives the mounting rod 23 to rotate synchronously. The mounting rod 23 slides inside the slide groove 8 and will not affect the normal rotation of the bearing shaft 9. Then, the rotating rod 7 is rotated in the opposite direction by hand until the mounting rod 23 slides and can no longer slide. At this time, the bearing shaft 9 remains in a vertical state and returns to its original position.

[0026] The guide rod 21 is spline-connected with the through hole 20, and a limit plate 13 is installed at the bottom of the load-bearing shaft 9. The diameter of the limit plate 13 is the same as the diameter of the feeding port 2. A through hole 20 is opened inside the limit plate 13, and the guide rod 21 is inserted into the through hole 20. Fixed rods 22 are installed on both sides of the feeding frame 3, and the other end of the fixed rod 22 is installed with a limit rod 10. The inside of the limit rod 10 and the side of the frame 1 are both provided with a slide groove 8. The center of the slide groove 8 is on the extension line of the straight line formed by the center of the two fixing rings 5. An installation rod 23 passes through the inside of the slide groove 8, and the other end of the installation rod 23 is fixed to the limit plate 13. A through groove 14 is opened on the side of the frame 1, and the through groove 14 is connected to the slide groove 8.

[0027] When it is necessary to replace sealing rings of different specifications, the mounting rod 23 is pushed upward by hand, and the mounting rod 23 slides inside the slide groove 8 until the mounting rod 23 slides to the uppermost position of the slide groove 8, and the loading frame 3 is pulled upward by hand. The loading frame 3 moves upward and drives the fixing rod 22 to move upward synchronously. The fixing rod 22 moves upward and drives the limit rod 10 to move upward synchronously. The limit rod 10 moves upward and pulls the mounting rod 23 to move upward synchronously. The mounting rod 23 moves upward and drives the limit plate 13 to move upward synchronously. The limit plate 13 moves upward and drives the bearing shaft 9 to move upward synchronously. Move, the load-bearing shaft 9 gradually separates from the guide rod 21 during the upward movement, the loading frame 3 and the load-bearing shaft 9 are disassembled, and then a new workpiece is taken and inserted into the interior of the frame 1, and the loading frame 3 is snapped on the frame 1, and the new load-bearing shaft 9 and the limit plate 13 are sleeved on the guide rod 21 until the bottom of the limit plate 13 contacts the base 15 and the loading frame 3 can no longer be pushed downward, that is, the installation of the new workpiece is realized, and the sealing ring can be replaced according to its specifications, so that the use range of the trimming device is greatly improved, and sealing rings of different specifications do not need corresponding trimming devices, thereby reducing production and processing costs.

[0028] A servo motor 16 is installed on the side of the frame 1, and a transmission rod 17 is installed on the output end of the servo motor 16. Two groups of bevel gears 19 are arranged between the transmission rod 17 and the base 15. Each group of bevel gears 19 consists of two bevel gears 19 meshing with each other. The length of the blade 12 is equal to the height of the load-bearing shaft 9. The trimming side of the blade 12 is aligned with the side of the loading port 2. The rotation angle of the load-bearing shaft 9 is greater than 90 degrees and less than 180 degrees. A collection frame 4 is leaning against the side of the frame 1. The collection frame 4 collects rubber seals. The loading port 2 is located directly above the load-bearing shaft 9, and the loading port 2 corresponds to the load-bearing shaft 9 one by one.

[0029] During trimming, the servo motor 16 runs to rotate the transmission rod 17, and the rotation of the transmission rod 17 drives the vertical bevel gear 19 to rotate synchronously. The vertical bevel gear 19 rotates to drive the horizontal bevel gear 19 to rotate, and the horizontal bevel gear 19 drives the base 15 and the guide rod 21 to rotate synchronously. Due to the spline connection between the guide rod 21 and the through hole 20, the rotation of the guide rod 21 drives the limit plate 13 and the load-bearing shaft 9 to rotate synchronously. The rotation of the load-bearing shaft 9 causes the sleeved sealing ring to rotate synchronously. The rotation of the sealing ring makes the surrounding areas contact with the blade 12, and the blade 12 trims the surrounding areas of the sealing ring. Multiple sealing rings can be trimmed at one time.
