Description

Technical Field

[0001] This utility model belongs to the field of rubber parts processing technology, specifically relating to a device for cutting the burrs of circular rubber parts. Background Technology

[0002] Circular rubber parts refer to circular or ring-shaped components made of rubber materials. They typically have elastic, sealing, shock-absorbing, insulating, or protective functions and are widely used in industries such as industry, machinery, automobiles, electronics, and home appliances.

[0003] The flash on round rubber parts is mainly due to the presence of tiny gaps on the mold parting surface during high-pressure vulcanization, which are then penetrated by the rubber material as it flows at high temperatures. At the same time, the material flowability, vulcanization pressure, and temperature control need to be balanced. While excessively high parameters can ensure the integrity of the filling, they can also easily lead to overflow. Therefore, after the round rubber parts are produced, a cutting device is needed to remove the flash.

[0004] Currently, the common way to cut the burrs on round rubber parts is by having workers trim them with scissors. Although this method can remove the burrs from round seals, it is inefficient in practice. Furthermore, using scissors to trim the round rubber parts cannot guarantee the flatness of the cut, which will affect the quality of the round rubber parts. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of low efficiency and poor quality in cutting the burrs of circular rubber parts in the prior art, and to provide a device for cutting the burrs of circular rubber parts.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A device for cutting the burrs of a circular rubber part includes a worktable. A fixing mechanism is provided above the worktable, and the fixing mechanism includes a housing for fixing the circular rubber part. A rotating mechanism is provided below the housing for rotating the housing. A movable block is provided above the worktable at a position corresponding to the housing. A connecting rod is connected to the side of the movable block near the housing. A cutting blade is connected to the lower end of the connecting rod near the housing. A movable groove is provided on the worktable at a position corresponding to the movable block. The movable block is movably connected in the movable groove. A lead screw is rotatably connected in the movable groove at a position corresponding to the movable block. The end of the lead screw away from the housing passes through the worktable and is connected to a third motor fixed on the worktable.

[0008] Preferably, the fixing mechanism also includes a turntable, which is located inside the upper part of the housing. The turntable has four circumferentially arranged spiral grooves. The housing has four circumferentially arranged sliding grooves at the corresponding positions of the spiral grooves. I-shaped sliders are slidably connected to the corresponding spiral grooves and sliding grooves. A positioning block is connected to the upper surface of the I-shaped slider. A first motor is connected to the lower center of the turntable and is installed inside the housing.

[0009] Preferably, the rotating mechanism includes a gear ring connected to the lower outer side of the housing, and a gear is provided above the worktable at the position corresponding to the gear ring. The gear ring meshes with the gear, and a second motor is connected to the middle of the lower surface of the gear.

[0010] Preferably, the outer shell is circular, the end of the positioning block is semi-circular, and the placement platform is set at the same center as the outer shell.

[0011] Preferably, a circular placement platform is connected to the outer surface of the workbench at a position corresponding to the outer shell, and the outer shell is rotatably connected to the middle of the placement platform.

[0012] Preferably, a positioning rod is connected to the position of the movable block within the movable slot, and the movable block is slidably connected to the positioning rod.

[0013] Preferably, an operator is installed above the workbench at the position corresponding to the placement table, and a cutting sensor is connected to the side of the workbench near the outer casing.

[0014] The beneficial effects of this utility model are:

[0015] This utility model

[0016] Place the circular rubber part on the placement platform, ensuring it is positioned outside the outer casing. Once placed, the cutting sensor will detect the rubber part, activating the first motor. This motor drives the turntable, which, with the cooperation of the spiral groove, sliding groove, and I-beam slider, causes the I-beam slider to move the four positioning blocks away from each other, bringing them closer to the inner wall of the circular rubber part and securing it. After the rubber part is secured, the first motor stops, and the cutting sensor activates the third motor. This motor drives the lead screw, which, with the assistance of the positioning rod, moves the moving plate, which in turn moves the cutting blade closer to the circular rubber part. The cutting blade is positioned at the burr edge of the circular rubber part. After the cutting blade has moved, the cutting sensor activates the second motor, which drives the gear to rotate. The gear rotates, which in turn rotates the gear ring, causing the outer casing and the circular rubber part to rotate. This allows the burr edge of the circular rubber part to be cut. After cutting, the first and third motors reverse, moving the cutting blade and positioning block away from the circular rubber part. At this point, the circular rubber part can be removed from the placement table, and the burr edge of the next circular rubber part can be cut. After cutting the burr edge of the circular rubber part, the flatness of the circular rubber part can be ensured, making it more convenient to use and improving work efficiency.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] Please see Figure 1 - Figure 6 As shown, a device for cutting the burrs of a circular rubber part includes a worktable 1, and a fixing mechanism is provided above the worktable 1 for fixing the circular rubber part.

[0031] The fixing mechanism includes a housing 2, which is used to assist in adjusting the position of the positioning block 26.

[0032] The outer shell 2 is circular, which makes it easy to place the circular rubber parts on the outside of the outer shell 2.

[0033] A turntable 21 is provided on the upper part of the inner shell 2. The position of the I-shaped slider 25 and the positioning block 26 can be adjusted by rotating the turntable 21.

[0034] The turntable 21 has four circumferentially arranged spiral grooves 23, and the outer shell 2 has four circumferentially arranged sliding grooves 24 at the corresponding positions of the spiral grooves 23. I-shaped sliders 25 are slidably connected in the corresponding spiral grooves 23 and sliding grooves 24. Through the cooperation of the I-shaped sliders 25, spiral grooves 23 and sliding grooves 24, when the turntable 21 rotates, it can drive the four positioning blocks 26 to move closer or further away from each other.

[0035] The upper surface of the I-beam is connected to a positioning block 26. Through the cooperation of the four positioning blocks 26, the inner wall of the circular rubber part can be squeezed, thereby fixing the circular rubber part. When cutting the edge of the circular rubber part, it can be more accurate and stable.

[0036] The end of the positioning block 26 is semi-circular. This design ensures that the circular rubber part can be fixed without damaging the inner wall of the circular rubber part.

[0037] A first motor 22 is connected to the lower center of the turntable 21. The first motor 22 is installed inside the outer casing 2 and is used to drive the turntable 21 to rotate.

[0038] A rotating mechanism is provided at the bottom of the outer casing 2, which is used to rotate the outer casing 2.

[0039] The rotating mechanism includes a gear ring 4, which is connected to the lower outer side of the outer shell 2. A gear 41 is provided on the upper part of the worktable 1 corresponding to the position of the gear ring 4. The gear ring 4 meshes with the gear 41. Through the cooperation between the gear 41 and the gear ring 4, when the gear 41 rotates, it can drive the gear ring 4 and the outer shell 2 to rotate, thereby driving the circular rubber part to rotate. When the circular rubber part rotates, the burrs can be cut off quickly and accurately.

[0040] A second motor 42 is connected to the middle of the lower surface of gear 41, and the second motor 42 is used to drive gear 41 to rotate.

[0041] The workbench 1 has a mounting slot 43 corresponding to the position of the second motor 42. The second motor 42 is installed in the mounting slot 43. The mounting slot 43 is used to store the second motor 42 and avoid the second motor 42 occupying a large volume.

[0042] A circular placement platform 3 is connected to the outer side of the upper surface of the workbench 1 at the position corresponding to the outer shell 2. The outer shell 2 is rotatably connected to the middle of the placement platform 3. The placement platform 3 is used to place the circular rubber parts and can also shield the gear 41 and the gear ring 4.

[0043] The placement platform 3 is set at the same center as the outer shell 2. This arrangement ensures that the circular rubber parts can be placed evenly on the placement platform 3.

[0044] A movable block is provided above the workbench 1 at the position corresponding to the outer shell 2. The movable block is used to adjust the position of the cutting blade 52 according to the size of the circular rubber part.

[0045] A connecting rod 51 is connected to the side of the movable block near the outer shell 2. A cutting blade 52 is connected to the lower end of the connecting rod 51 near the outer shell 2. The cutting blade 52 is used to cut the burrs of the circular rubber parts.

[0046] The workbench 1 has a movable slot 53 corresponding to the position of the movable block. The movable block is movably connected in the movable slot 53. By opening the movable slot 53, it is ensured that the movable block can move.

[0047] A lead screw 54 is rotatably connected to the position of the movable block within the movable groove 53. The position of the movable block can be adjusted by rotating the lead screw 54.

[0048] The end of the lead screw 54 away from the outer casing 2 passes through the worktable 1 and is connected to the third motor 55 fixed on the worktable 1. The third motor 55 is used to drive the lead screw 54 to rotate.

[0049] A positioning rod 56 is connected to the position of the movable block in the movable groove 53. The movable block and the positioning rod 56 are slidably connected. The positioning rod 56 is used to limit the position of the movable block and prevent the positioning rod 56 from deflecting during rotation.

[0050] An operator 11 is provided above the workbench 1 at the position corresponding to the placement table 3. The operator 11 is used to control the device.

[0051] A cutting sensor 12 is connected to the side of the workbench 1 near the outer casing 2. The cutting sensor 12 is used to sense the circular rubber part. After the cutting sensor 12 senses the circular rubber part, the first motor 22 is started to fix the circular rubber part, and the third motor 55 is started to bring the cutting blade 52 close to the circular rubber part. Finally, the second motor 42 is started to rotate the circular rubber part and cut the burrs on the circular rubber part.

[0052] In practical use, the circular rubber part is placed on the placement platform 3, with the circular rubber part positioned outside the outer shell 2. After placement, the cutting sensor 12 senses the circular rubber part, thus activating the first motor 22. The first motor 22 drives the turntable 21 to rotate. With the cooperation of the spiral groove 23, the sliding groove 24, and the I-beam slider 25, the turntable 21 causes the I-beam slider 25 to move the four positioning blocks 26 away from each other, bringing the four positioning blocks 26 closer to the inner wall of the circular rubber part and fixing the circular rubber part. After the circular rubber part is fixed, the first motor 22 stops running, and the cutting sensor 12 activates the third motor 55. The third motor 55 drives the lead screw 54 to rotate. With the cooperation of the positioning rod 56, the lead screw 54 causes the moving plate 5 to drive the cutting blade. 52 moves closer to the circular rubber part and aligns the cutting blade 52 with the burr edge of the circular rubber part. After the cutting blade 52 has moved, the cutting sensor 12 will activate the second motor 42. The second motor 42 drives the gear 41 to rotate, the gear 41 rotates, and the gear 4 rotates, causing the outer shell 2 and the circular rubber part to rotate, thereby cutting the burr edge of the circular rubber part. After cutting, the first motor 22 and the third motor 55 will reverse, causing the cutting blade 52 and the positioning block 26 to move away from the circular rubber part. At this time, the circular rubber part is removed from the placement table 3, and the burr edge of the next circular rubber part can be cut. After cutting the burr edge of the circular rubber part, the flatness of the circular rubber part can be ensured, which is more convenient to use and can improve work efficiency.
