Description

Technical Field

[0001] This utility model relates to the field of sealing ring processing technology, and in particular to a sealing ring trimming machine. Background Technology

[0002] An O-ring is a circular elastic sealing device primarily used for static and reciprocating motion sealing to prevent liquid or gas leakage. The choice of material directly affects its sealing performance and service life. Commonly used materials include nitrile rubber and fluororubber, suitable for applications such as bearing seals and hydraulic systems. During the manufacturing process, excess burrs may remain on the sidewalls of the O-ring. To ensure better quality, these burrs are typically trimmed using a trimming machine.

[0003] In the existing Chinese utility model publication CN216182087U, a trimming and cutting device for processing rubber sealing rings is disclosed. The device includes a base, a first support rod, and a top plate. The first support rod is fixedly connected to the top of the base, and the top plate is fixedly connected to the top of the first support rod. A first telescopic cylinder and a second telescopic cylinder are fixedly connected to the bottom of the top plate. A cutting blade is fixedly connected to the bottom of the output end of the first telescopic cylinder, and a grinding disc is fixedly connected to the bottom of the output end of the second telescopic cylinder. A linear motor is fixedly connected to the top of the base, and a sliding groove is provided on the top of the base. A drive motor is slidably connected to the top of the base through the sliding groove. This device enables rapid trimming and cutting of excess burrs on rubber sealing rings. Simultaneously, the trimmed area can be ground smooth. Waste generated during operation is collected into a collection box by a negative pressure fan, ensuring a good working environment.

[0004] Referring to the aforementioned trimming and cutting device for processing rubber sealing rings, this device fixes the sealing ring by fitting it onto a sealing ring sleeve. However, the diameter of this sleeve is fixed, making it only suitable for fixing sealing rings of a fixed size. It cannot effectively fix sealing rings of different diameters, resulting in a lack of flexibility in the overall fixing operation. Therefore, how to better fix sealing rings of different diameters, making the fixing operation of the entire trimming machine more flexible, is an important problem that needs to be solved in the design of sealing ring trimming machines. Utility Model Content

[0005] This invention addresses the problem that the sealing ring sleeve cannot effectively fix sealing rings of different diameters, and that the overall fixing operation is not flexible enough, by providing a sealing ring trimming machine.

[0006] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0007] This utility model provides a sealing ring trimming machine, including a supporting base plate, and further including: four supporting rods fixedly connected to the top side wall of the supporting base plate, and a supporting top plate fixedly connected to the top side wall of the four supporting rods;

[0008] A support structure, wherein the support structure is disposed on a support base plate;

[0009] A clamping and fixing structure is provided on the top support plate, and the clamping and fixing structure cooperates with the support structure to clamp and fix it;

[0010] A rotating structure is mounted on a supporting base plate;

[0011] A sealing ring trimming structure is provided on the rotating structure.

[0012] Preferably, four support feet are fixedly connected to the bottom side wall of the support base plate.

[0013] Preferably, the support structure includes a support column, a fixing ring, a support base, and a fixing ring plate. The support base is fixedly connected to the top side wall of the support base plate. The support column is fixedly connected to the top side wall of the support base. The side wall of the support column is circular and narrows inward. A fixing ring is fixedly connected to the side wall of the support column. A fixing ring plate is fixedly connected to the side wall of the support base.

[0014] In this technical solution, the circular, inwardly tapering sidewalls on the support column can better accommodate the fitting of sealing rings of different diameters.

[0015] Preferably, the rotating structure includes a fixed ring frame, a rotating gear ring, a rotating gear, a rotating rod, and a second motor. The rotating gear ring is rotatably connected to the side wall of the supporting base plate. A fixed ring frame is fixedly connected to the top side wall of the rotating gear ring. The fixed ring frame is rotatably connected to a fixed ring plate, which is located between the rotating gear ring and the fixed ring frame. The second motor is fixedly connected to the bottom side wall of the supporting base plate. A rotating rod is fixedly connected to the rotating end of the second motor. The rotating rod is rotatably connected to the side wall of the supporting base plate. A rotating gear is fixedly connected to the top of the rotating rod. The rotating gear and the rotating gear ring mesh with each other.

[0016] In this technical solution, the rotation of the second motor drives the rotating rod to rotate, the rotating rod drives the rotating gear to rotate, the rotating gear rotates inside the rotating gear ring, driving the rotating gear ring to rotate, the rotating gear ring drives the fixed ring frame to rotate, the fixed ring frame drives the fixed rod to rotate, and the fixed rod drives the grinding block to rotate around the sealing ring.

[0017] Preferably, the sealing ring trimming structure includes a fixed rod, a second fixed plate, a lifting block, and a second electric push rod. The fixed rod and the second electric push rod are both fixedly connected to the top side wall of the fixed ring frame. The fixed rod is located on both sides of the second electric push rod. The top of the fixed rod is fixedly connected to the second fixed plate. The lifting block is slidably connected to the side wall of the fixed rod. The top of the second electric push rod is fixedly connected to the bottom side wall of the lifting block.

[0018] In this technical solution, the electric push rod shortens to drive the lifting block to descend, the lifting block drives the support frame to descend, and the support frame drives the grinding block to descend, thus allowing the height of the grinding block to be adjusted according to the height of the sealing ring.

[0019] Preferably, the sealing ring trimming structure includes a support frame, an electric push rod three, a motor one, and a grinding block. The electric push rod three is fixedly connected to the side wall of the lifting block, and the other end of the electric push rod three is fixedly connected to the support frame. The support frame is slidably connected to the side wall of the lifting block. The end side wall of the support frame is set into an arc-shaped structure. The motor one is fixedly connected to the top side wall of the support frame, and the rotating end of the motor one is fixedly connected to the grinding block.

[0020] In this technical solution, the electric push rod shortens to drive the support frame to move, and the support frame drives the grinding block to move. The grinding block is moved and adjusted according to the distance between the grinding block and the sealing ring, so that the grinding block fits against the side wall of the sealing ring. The height and moving distance of the grinding block are adjusted accordingly according to the position of the sealing ring.

[0021] Preferably, the clamping and fixing structure includes a fixing plate, an electric push rod, a sliding rod, and a clamping ring. The sliding rod is slidably connected to the side wall of the supporting top plate. A circular clamping ring is fixedly connected to the bottom of the sliding rod, and the fixing plate is fixedly connected to the top of the sliding rod. An electric push rod is fixedly connected between the fixing plate and the supporting top plate.

[0022] In this technical solution, the electric push rod shortens, causing the fixed plate to descend. The fixed plate then causes the sliding rod to slide downwards, which in turn pushes the clamping ring downwards. The clamping ring then causes the clamping frame to be sleeved onto the support column.

[0023] Preferably, the clamping and fixing structure includes a clamping frame, a second sliding rod, a spring, and a friction ring. The friction ring is fixedly connected to the side wall of the clamping ring at equal intervals. The second sliding rod is slidably connected to the inner side wall of the friction ring. Both ends of the second sliding rod are fixedly connected to the inner side wall of the clamping frame. The clamping frame is slidably connected to the side wall of the clamping ring at equal intervals. A spring is fixedly connected between the side wall of the clamping ring and the clamping frame. The spring is sleeved on the outer side of the second sliding rod.

[0024] In this technical solution, as the clamping frame descends, the gradually widening diameter of the support column pushes the clamping frame outward, and the spring is stretched, allowing the clamping frame to better cooperate with the support column. After the bottom side wall of the clamping frame contacts the sealing ring, it will simultaneously push the sealing ring downward until the sealing ring moves to the part of the support column that matches its own inner ring diameter. The sealing ring and the support column are tightly fitted together, and the sealing ring is fixed and restricted on the support column.

[0025] Preferably, the side wall of the clamping frame near the support column is configured as an arc-shaped structure, and the side wall of the clamping frame near the support column is inclined.

[0026] Preferably, the angle of inclination of the side wall of the clamping frame matches the side wall of the support column.

[0027] In this technical solution, the side wall of the clamping frame and the side wall of the support column are well fitted together.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0029] The positive and progressive effects of this utility model are as follows:

[0030] 1. By attaching the sealing ring to the support column, the electric push rod shortens, causing the clamping ring to descend. The clamping ring then moves the clamping frame onto the support column. As the clamping frame descends, the gradually widening diameter of the support column pushes the clamping frame outward. When the bottom side wall of the clamping frame contacts the sealing ring, it simultaneously pushes the sealing ring downward until the sealing ring moves to the support column where its inner ring diameter matches. The sealing ring and the support column are tightly fitted, thus fixing the sealing ring to the support column. This facilitates better clamping and fixing of sealing rings of different diameters, making the fixing operation of the entire trimming machine more flexible.

[0031] 2. The grinding block is lowered by shortening the second electric push rod, and the height of the grinding block can be adjusted according to the height of the sealing ring. The grinding block is moved by shortening the third electric push rod, and the distance between the grinding block and the sealing ring can be adjusted to make the grinding block fit against the side wall of the sealing ring. This makes it easier to adjust the height and moving distance of the grinding block according to the position of the sealing ring.

[0032] 3. The grinding block is rotated by motor one, and the rotating gear is rotated by motor two. The rotating gear is rotated by rotating gear ring, and the rotating gear ring is rotated by rotating grinding block around the sealing ring, which facilitates the grinding and trimming of excess burrs around the sealing ring.

[0044] Rotating structure 8, which is mounted on the supporting base plate 1;

[0045] The sealing ring trimming structure 7 is disposed on the rotating structure 8.

[0046] Four support feet 4 are fixedly connected to the bottom side wall of the support base plate 1.

[0047] The support structure 5 includes a support column 501, a fixing ring 502, a support base 503, and a fixing ring plate 504.

[0049] The rotating structure 8 includes a fixed ring frame 801, a rotating gear ring 802, a rotating gear 803, a rotating rod 804, and a second motor 805. The rotating gear ring 802 is rotatably connected to the side wall of the supporting base plate 1. The fixed ring frame 801 is fixedly connected to the top side wall of the rotating gear ring 802. The fixed ring frame 801 is rotatably connected to a fixed ring plate 504, which is located between the rotating gear ring 802 and the fixed ring frame 801.

The rotating gear 803 and the rotating gear ring 802 mesh with each other.

[0050] The rotation of motor 805 drives the rotating rod 804 to rotate, which in turn drives the rotating gear 803 to rotate. The rotating gear 803 rotates within the rotating gear ring 802, causing the rotating gear ring 802 to rotate. The rotating gear ring 802 drives the fixed ring frame 801 to rotate, which in turn drives the fixed rod 701 to rotate. The fixed rod 701 then drives the grinding block 714 to rotate around the sealing ring.

[0051] The sealing ring trimming structure 7 includes a fixing rod 701, a second fixing plate 702, a lifting block 703, and a second electric push rod 704.

The lifting block 703 is slidably connected to the side wall of the fixing rod 701. The top of the second electric push rod 704 is fixedly connected to the bottom side wall of the lifting block 703.

[0052] The electric push rod 704 shortens, causing the lifting block 703 to descend. The lifting block 703 causes the support frame 711 to descend, and the support frame 711 causes the grinding block 714 to descend. The height of the grinding block 714 can be adjusted according to the height of the sealing ring.

[0053] The sealing ring trimming structure 7 includes a support frame 711, an electric push rod 712, a motor 713, and a grinding block 714. The electric push rod 712 is fixedly connected to the side wall of the lifting block 703. The other end of the electric push rod 712 is fixedly connected to the support frame 711. The support frame 711 is slidably connected to the side wall of the lifting block 703. The end side wall of the support frame 711 is set in an arc shape. The motor 713 is fixedly connected to the top side wall of the support frame 711. The rotating end of the motor 713 is fixedly connected to the grinding block 714.

[0054] The electric push rod 712 shortens, causing the support frame 711 to move. The support frame 711 then moves the grinding block 714. The grinding block 714 can be adjusted according to its distance from the sealing ring, so that it fits against the side wall of the sealing ring. The height and moving distance of the grinding block 714 can be adjusted accordingly based on the position of the sealing ring.

[0055] The clamping and fixing structure 6 includes a fixing plate 601, an electric push rod 602, a sliding rod 603, and a clamping ring 604. The sliding rod 603 is slidably connected to the side wall of the supporting top plate 3. A circular clamping ring 604 is fixedly connected to the bottom of the sliding rod 603. The fixing plate 601 is fixedly connected to the top of the sliding rod 603. An electric push rod 602 is fixedly connected between the fixing plate 601 and the supporting top plate 3.

[0056] The electric push rod 602 shortens, causing the fixed plate 601 to descend. The fixed plate 601 causes the sliding rod 603 to slide downward. The sliding rod 603 pushes the clamping ring 604 to descend. The clamping ring 604 causes the clamping frame 611 to be sleeved onto the support column 501.

[0057] The clamping and fixing structure 6 includes a clamping frame 611, a sliding rod 612, a spring 613, and a friction ring 614. The friction ring 614 is fixedly connected to the side wall of the clamping ring 604 at equal distances. The sliding rod 612 is slidably connected to the inner side wall of the friction ring 614. Both ends of the sliding rod 612 are fixedly connected to the inner side wall of the clamping frame 611. The clamping frame 611 is slidably connected to the side wall of the clamping ring 604 at equal distances. A spring 613 is fixedly connected between the side wall of the clamping ring 604 and the side wall of the clamping frame 611. The spring 613 is sleeved on the outer side of the sliding rod 612.

[0058] As the clamping frame 611 descends, the gradually widening diameter of the support column 501 pushes the clamping frame 611 outward, stretching the spring 613. This allows the clamping frame 611 to better engage with the support column 501. After the bottom side wall of the clamping frame 611 contacts the sealing ring, it simultaneously pushes the sealing ring downward until the sealing ring moves to the part of the support column 501 that matches its inner ring diameter. The sealing ring then tightly fits the support column, and the sealing ring is fixedly restricted on the support column 501.

[0059] The side wall of the clamping frame 611 near the support column 501 is configured as an arc-shaped structure, and the side wall of the clamping frame 611 near the support column 501 is inclined.

[0060] The angle of inclination of the side wall of the clamping frame 611 is matched with the side wall of the support column 501.

[0061] This ensures that the side wall of the clamping frame 611 fits well with the side wall of the support column 501.

[0062] In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. When trimming the sealing ring, the sealing ring is fitted onto the support column 501. The electric push rod 602 shortens, causing the fixing plate 601 to descend. The fixing plate 601 causes the sliding rod 603 to slide downward. The sliding rod 603 pushes the clamping ring 604 to descend. The clamping ring 604 causes the clamping frame 611 to fit onto the support column 501. As the clamping frame 611 descends, the gradually widening diameter of the support column 501 pushes the clamping frame 611 to move outward. The spring 613 is stretched, allowing the clamping frame 611 to cooperate well with the support column 501. After the bottom side wall of the clamping frame 611 contacts the sealing ring, it will simultaneously push the sealing ring downward until the sealing ring moves to the part of the support column 501 that matches its inner ring diameter. The sealing ring is tightly fitted onto the support column 501 and is fixed and restricted, preventing it from moving.

[0063] Electric push rod 2 704 shortens, causing lifting block 703 to descend. Lifting block 703 causes support frame 711 to descend. Support frame 711 causes grinding block 714 to descend. The height of grinding block 714 can be adjusted according to the height of the sealing ring. Electric push rod 3 712 shortens, causing support frame 711 to move. Support frame 711 causes grinding block 714 to move. The distance between grinding block 714 and sealing ring can be adjusted to make grinding block 714 fit against the side wall of sealing ring. The height and moving distance of grinding block 714 can be adjusted accordingly according to the position of sealing ring.

[0064] Motor 1 713 drives the grinding block 714 to rotate, motor 2 805 rotates the rotating rod 804 to rotate, the rotating rod 804 drives the rotating gear 803 to rotate, the rotating gear 803 rotates inside the rotating gear ring 802, driving the rotating gear ring 802 to rotate, the rotating gear ring 802 drives the fixed ring frame 801 to rotate, the fixed ring frame 801 drives the fixed rod 701 to rotate, and the fixed rod 701 drives the grinding block 714 to rotate around the sealing ring. The rotating grinding block 714 effectively grinds and trims the excess burrs around the sealing ring.
