[0027] As Figures 1 to 5 shown, a rubber seal trimming machine includes: a machine shell 1, a cleaning component 3 for cleaning the residue after trimming the rubber seal, and a grinding component 4 for trimming the rubber seal.

[0028] First, the machine shell 1 is cleaned once by the cleaning component, and then the rubber seal is trimmed by the grinding component 4. After the trimming of the rubber seal is completed, the inside of the machine shell 1 is cleaned a second time to ensure the cleanliness of the inside of the machine shell 1.

[0029] The cleaning component 3 includes a rotating motor 31, a rotating column 32, a first gear 33, a second gear 34, a rotating brush 35, and a collection box 36; the output end of the rotating motor 31 is fixedly connected to the rotating column 32, the rotating column 32 is fixedly connected to the first gear 33, the first gear 33 meshes with the second gear 34, the second gear 34 is fixedly connected to the rotating brush 35, the machine shell 1 is slidably connected to the collection box 36, there are two sets of the second gears 34, and the two sets of the second gears 34 rotate in opposite directions. Two sets of grooves are formed in the machine shell 1, and the collection box 36 is placed inside; when it is necessary to pre-clean the inside of the machine shell 1, the rotating motor 31 is started, so that the rotating motor 31 drives the rotating column 32 to rotate, and drives the transmission between the first gear 33 and the second gear 34 through the rotating column 32, so that the two rotating brushes 35 under the second gear 34 rotate in the same direction. The two rotating brushes 35 rotate towards the two grooves at the same time to clean the dust and rubber burrs on the inner surface of the machine shell 1, so that the rubber burrs fall into the grooves, and the rubber burrs are collected by the collection box 36 to prevent them from splashing.

[0030] The grinding assembly 4 is composed of a telescopic rod 41, an outer grinding plate 42, a filter plate 43, and an inner grinding assembly 44; the telescopic rod 41 is fixedly connected to the outer grinding plate 42, the outer grinding plate 42 is slidably connected to the filter plate 43, the filter plate 43 is provided with holes, the surface of the telescopic rod 41 is provided with limit holes, and the rotating column 32 is fixedly connected to one end of the telescopic rod 41, and the other end of the telescopic rod 41 is fixedly connected to the outer grinding plate 42; when the rotating motor 31 rotates, it will drive the rotating column 32 to rotate accordingly. When the rotating column 32 rotates, the telescopic rod 41 will also rotate accordingly, and drive the outer grinding plate 42 to rotate around the center of the rotating column 32 to trim the outer circle of the rubber seal. At the same time, the trimmed burrs and flash will fall onto the filter plate 43 and then fall into the collection box 36 placed inside the machine shell 1. At the same time, the distance of the telescopic rod 41 is adjustable. According to the diameter of the rubber seal, the distance between the outer grinding plate 42 and the center of the rotating column 32 can be adjusted to closely fit the outer circle of the rubber seal, so as to achieve a better deburring effect;

[0031] The inner grinding assembly 44 includes a rotating ring 441, a threaded column 442, a connecting rod 443, and an inner grinding plate 444; the rotating ring 441 is threadedly connected to the threaded column 442, the rotating ring 441 is rotatably connected to one end of the connecting rod 443, the other end of the connecting rod 443 is rotatably connected to the inner grinding plate 444, and multiple groups of the connecting rod 443 and the inner grinding plate 444 are provided and arranged in an array along the center of the rotating ring 441; at the same time, when deburring the inner wall of the rubber ring seal, deburring is also required. By rotating the rotating ring 441, the rotating ring 441 is driven to move up and down on the surface of the threaded rod. When the rotating ring 441 moves downward, one end of the connecting rod 443 will be driven to move towards the bottom of the threaded column 442. Since the other end of the connecting rod 443 is connected to the bottom of the inner grinding plate 444, when the rotating ring 441 moves to the bottom of the threaded rod, the four inner grinding plates 444 are the farthest apart, the diameter of the formed circle is the largest, and the depth of the inner circle of the rubber ring seal that can be clamped is the deepest. Therefore, by rotating the rotating ring 441, the inner grinding plate 444 can be gradually approximated to the inner circle of the rubber seal until it completely fits the inner circle of the rubber seal;

[0032] As a supplement: when deburring the inner circle of the rubber ring is required, the inner grinding plate 444 is adjusted to closely fit the inner wall of the rubber ring, and the inner circle of the rubber ring is helped to rub against the inner grinding plate 444 during rotation, so as to be able to deburr the inner circle of the rubber ring.

[0033] Working principle:

[0034] When it is necessary to pre-clean the inside of the casing 1, start the rotating motor 31, so that the rotating motor 31 drives the rotating column 32 to rotate, and drives the transmission between the first gear 33 and the second gear 34 through the rotating column 32, so that the two rotating brushes 35 under the second gear 34 rotate in the same direction. The two rotating brushes 35 rotate towards the two grooves at the same time to clean the dust and rubber burrs on the inner surface of the casing 1. Through the mutual cooperation between the inner grinding plate 444 and the outer grinding plate 42, the two plate bodies can remove the burrs of the rubber ring seals with different inner and outer circles, and at the same time clean and collect the sputtered burrs to prevent the burrs from sticking to the internal parts of the machine and being difficult to clean. When the rotating motor 31 rotates, it will drive the rotating column 32 to rotate accordingly. When the rotating column 32 rotates, the telescopic rod 41 will also rotate accordingly, and drive the outer grinding plate 42 to rotate around the center of the rotating column 32 to trim the outer circle of the rubber seal. And, according to the diameter of the rubber seal, the distance between the outer grinding plate 42 and the center of the rotating column 32 can be adjusted to closely fit the outer circle of the rubber seal to achieve a better burr removal effect. At the same time, when it is necessary to remove the burrs of the inner circle of the rubber ring, by adjusting the inner grinding plate 444, it closely fits the inner wall of the rubber ring to help the rubber ring rub against the inner grinding plate 444 when rotating the inner circle, so as to be able to remove the burrs of the inner circle of the rubber ring.
