[0035] like Figure 1-Figure 2 As shown, a batch sealing ring deburring device includes a workbench 1, a cutting unit 2 and a fixing unit 3, wherein the cutting unit 2 and the fixing unit 3 are both located on the top of the workbench 1;

[0036] The cutting unit 2 includes a first frame 201, a cutting cylinder 202, a cover 203, several rotating motors 204, a placement rod 205, several threaded rods 206, an annular cutter 207 and several threaded openings 208; the first frame 201 is connected to the workbench 1, a cutting cylinder 202 is arranged on the top of the first frame 201, and the cutting cylinder 202 is connected to the first frame; a cover 203 and several rotating motors 204 are arranged at one end of the cutting cylinder 202, and the several rotating motors 204 are arranged around the cover 203, the cover 203 and the cutting cylinder 202 are detachable, and the rotating motor 204 is connected to the cutting cylinder 202; a placement rod is arranged inside the cutting cylinder 202 205, several threaded rods 206 and annular cutter 207; the cover body 203 and one end of the placement rod 205 are detachably arranged, and the other end of the placement rod 205 is connected to the inner wall of the cutting cylinder 202; the threaded rod 206 corresponds to the rotating motor 204 one by one, and the rotating end of the rotating motor 204 is connected to one end of the threaded rod 206 through the cutting cylinder 202, and the other end of the threaded rod 206 is rotatably connected to the inner wall of the cutting cylinder 202; the annular cutter 207 is provided with several threaded openings 208, and the threaded openings 208 correspond to the threaded rod 206 one by one, and the annular cutter 207 slides with the threaded rod 206 in the cutting cylinder 202 through the threaded openings 208.

[0037] The cutting cylinder 202 serves as a closed working space to prevent burrs from flying during the cutting process, and at the same time accommodates components such as the annular cutter 207, the threaded rod 206, and the placement rod 205. The rotating motor 204 drives the threaded rod 206 to rotate, driving the annular cutter 207 to move axially to complete the deburring operation on the edge of the sealing ring. The number of rotating motors 204 is at least two. The number of rotating motors 204 is at least two, which can make the annular cutter 207 more stable when moving and prevent it from shifting during movement. The placement rod 205 is used to fix the sealing ring to ensure that each sealing ring maintains the correct position and direction during the cutting process to avoid shifting or overlapping. The cover body 203 seals one end of the cutting cylinder 202 to facilitate the loading and unloading operation of the sealing ring. The cover body 203 is provided with a limit portion 7, the limit portion 7 is connected to the cover body 203, and the limit portion 7 and the placement rod 205 are detachably arranged. The limiting portion 7 leaves a space between the sealing ring and the cover body 203 to prevent the annular cutter 207 from cutting the sealing ring incompletely.

[0038] The fixing unit 3 includes a second frame 301, an electric push rod 302, a connecting block 303, a plurality of connecting rods 304 and an annular push plate 305; the second frame 301 is connected to the workbench 1, the electric push rod 302 is arranged on the top of the second frame 301, and the electric push rod 302 is connected to the second frame 301; a connecting block 303 is arranged at the telescopic end of the electric push rod 302, and the connecting block 303 is connected to the electric push rod 302, and the end of the connecting block 303 is away from the electric push rod 302 A plurality of connecting rods 304 are provided, and the plurality of connecting rods 304 are arranged in a circle on one side of the connecting block 303, and the connecting rods 304 are connected to the connecting block 303; one end of the connecting rod 304 away from the connecting block 303 enters into the interior of the cutting cylinder 202, and an annular push plate 305 is provided at one end of the connecting rod 304 located inside the cutting cylinder 202, and the annular push plate 305 is connected to the connecting rod 304, and the annular push plate 305 is slidably matched in the cutting cylinder 202 through the electric push rod 302.

[0039] The electric push rod 302 pushes the connecting block 303 and the connecting rod 304, so that the annular push plate 305 presses the sealing ring along the direction of the placement rod 205 to ensure that the sealing ring is firmly fixed during the cutting process. The annular push plate 305 can ensure uniform pressure on the sealing ring to avoid cutting quality problems caused by uneven pressure.

[0040] Specifically, the annular cutter 207, the placement rod 205, the annular push plate 305 and the cover body 203 are all coaxially arranged. The coaxial arrangement of the annular cutter 207, the placement rod 205, the annular push plate 305 and the cover body 203 ensures the cutting accuracy. When the sealing ring is sleeved on the placement rod 205 for cutting, if the annular cutter 207 is not coaxial with the placement rod 205, the cutting may cause the edge of the sealing ring to be cut unevenly, or even cut off or cut the main body of the sealing ring. At the same time, it is also crucial that the annular push plate 305 is coaxially arranged with the placement rod 205. The annular push plate 305 is used to fix the sealing ring. If it is not coaxial with the placement rod 205, the sealing ring may be deflected when fixed, affecting the cutting accuracy. The inner circle diameter of the annular cutter 207 is larger than the inner circle diameter of the annular push plate 305, and the inner circle diameter of the annular push plate 305 is larger than the cross-sectional diameter of the placement rod 205. The inner diameter of the annular cutter 207 is larger than the inner diameter of the annular push plate 305, ensuring that the annular cutter 207 does not cut the annular push plate 305 when cutting the burr of the sealing ring. The inner diameter of the annular push plate 305 is larger than the cross-sectional diameter of the placement rod 205, so that the annular push plate 305 can smoothly extrude the sealing ring.

[0041] A placement box 5 is provided at the lower part of the cutting cylinder 202 located on one side of the cover body 203 , and the placement box 5 is connected to the workbench 1 .

[0042] The placement box 5 is convenient for uniformly collecting the sealing rings after the burrs are removed.

[0043] The batch sealing ring deburring device also includes a burr collection unit 4, which includes a collection box 401, an exhaust duct 402 and an exhaust fan 403. The two ends of the exhaust duct 402 are respectively connected to the cutting cylinder 202 and the collection box 401, and the exhaust fan 403 is provided in the exhaust duct 402. The exhaust duct 402 is responsible for guiding the burrs generated inside the cutting cylinder 202 to the collection box 401 through airflow. The fan is the power source of the burr collection unit 4, and sucks out the burrs in the cutting cylinder 202 and sends them to the collection box 401 by providing a strong negative pressure suction force.

[0044] A filter screen 6 is arranged in the collection box 401, and the filter screen 6 is detachably connected to the collection box 401. The filter screen 6 can collect the cut burrs in a unified manner, which is convenient for the subsequent recycling work of the operator.

[0046] S1. Open the cover 203 of the cutting cylinder 202, and insert the sealing rings to be deburred one by one onto the placement rod 205 inside the cutting cylinder 202, ensuring that the sealing rings are arranged neatly and do not overlap;

[0047] S2, put the cover 203 back on the cutting cylinder 202, and ensure that the cover 203 is firmly connected to the cutting cylinder 202 and the placement rod 205 inside the cutting cylinder 202;

[0048] S3, start the electric push rod 302, so that its telescopic end pushes the connecting block 303, the connecting rod 304 and the annular push plate 305;

[0049] S4, confirm that the annular push plate 305 presses the sealing ring along the direction of the placement rod 205 to ensure that the sealing ring is firmly fixed during the cutting process and does not move;

[0050] S5, starting the rotating motor 204, and the rotating motor 204 drives the threaded rod 206 connected thereto to rotate;

[0051] S6, the threaded rod 206 rotates to drive the annular cutter 207 to slide along the threaded rod 206 and reciprocate axially inside the cutting cylinder 202;

[0052] S7, when the cutting is completed, the rotating motor 204 is stopped, and the annular cutter 207 is ensured to be located at the end of the cutting cylinder 202 away from the cover 203;

[0053] S8, stop the electric push rod 302, so that the annular push plate 305 cancels the thrust on the sealing ring;

[0054] S9, open the cover 203 of the cutting cylinder 202, restart the electric push rod 302, and push the annular push plate 305 to push the sealing ring away from the placement rod 205, and the sealing ring naturally falls into the placement box 5 at the bottom of the cutting cylinder 202 for collection.

[0055] The implementation principle of the batch sealing ring deburring device and the use method thereof of the present invention is as follows:

[0056] The sealing ring is loaded onto the placement rod 205 inside the cutting cylinder 202, and the placement rod 205 plays the role of directional support and arrangement of the sealing ring. The threaded rod 206 is driven to rotate by the rotary motor 204, so that the threaded rod 206 drives the annular cutter 207 to slide along the axial direction. The annular cutter 207 reciprocates and cuts the burrs of the sealing ring in the cutting cylinder 202 through the threaded sliding fit, thereby completing the burr removal operation.

[0057] The connecting rod 304 and the annular push plate 305 are driven by the electric push rod 302. The annular push plate 305 applies uniform pressure to the sealing ring along the direction of the placement rod 205 during operation to ensure that the sealing ring is firmly fixed and avoid poor cutting effect due to position deviation. The coaxial design of the annular push plate 305 ensures that the sealing ring always remains stable during the cutting process and perfectly matches the cutting path of the annular cutter 207, thereby achieving uniform cutting and high precision.

[0058] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
