Description

Technical Field

[0001] This invention relates to the field of rubber processing equipment technology, specifically a special rubber processing equipment and its processing method. Background Technology

[0002] A rubber seal is an annular cover composed of one or more parts, fixed to one of the bearing rings or washers and in contact with or forming a narrow labyrinth gap with another ring or washer to prevent lubricating oil leakage and foreign matter intrusion. Rubber seals will produce burrs during the production process. If the burrs are not cleaned, it will affect the use of the seal. At the same time, if the lip of the rubber ring is damaged when cleaning the burrs, it will reduce the service life of the seal and even cause the seal to be scrapped, which will seriously affect the production efficiency of the seal.

[0003] For example, Chinese Patent Publication No. CN211277763U discloses a grinding equipment for processing and producing rubber seals, which includes a frame, a column on one side of the frame, a grinding roller rotatably mounted on the column, a drive motor at one end of the grinding roller, a movable seat slidably mounted on the frame, and a chuck structure for holding rubber rings on the movable seat.

Detailed Implementation

[0029] Please see Figure 1-12 In this embodiment of the invention, a special rubber processing equipment includes a machine body 1. A right-angle bracket 2 is vertically fixed on one side of the machine body 1. A grinding component is rotatably mounted on the side of the machine body 1 near the right-angle bracket 2. The grinding component is rotatably connected to the top of the right-angle bracket 2. A grinding component is mounted on the machine body 1 away from the right-angle bracket 2. A placement component for clamping the rubber ring 6 is rotatably arranged on one side of the grinding component. The grinding component and the placement component are connected by a drive. An outer support component for expanding the rubber ring 6 outward is slidably fitted inside the placement component. When the outer support component slides outward from the placement component, the rubber ring 6 is expanded and fixed and comes into contact with the grinding component. A switch component for controlling the rotation of the grinding component is arranged on the right-angle bracket 2 near the grinding component. The switch component is electrically connected to the grinding component. An operating component is slidably arranged on the upper side of the right-angle bracket 2 near the placement component. One end of the operating component is located above the switch component and is in movable contact with the switch component. The other end of the operating component is located above the placement component and is in movable contact with the outer support component. When the operating component moves downward, it drives the outer support component to slide outward from the placement component and simultaneously drives the switch component to close.

[0030] In actual use, initially, the operating component and the switch component are not in contact, the switch is in the off state, the grinding component is stationary, and the operating component and the outer support component are not in contact; the outer support component is located inside the placement component. When it is necessary to grind the rubber ring 6, the rubber ring 6 is placed on the placement component. At this time, the rubber ring 6 is not in contact with the grinding component. The operating component is moved downward until it contacts the outer support component and presses it downward. The operating component drives the outer support component to slide out of the placement component, and the rubber ring 6 is opened and fixed, making contact with the grinding component. At the same time, the operating component contacts the switch component and presses it downward, causing the switch component to close. The grinding component rotates, causing the placement component to rotate, facilitating multi-angle grinding of the outer ring of the rubber ring 6. After grinding is complete, the operating component is moved upward, disengaging from the switch component and returning to the off state. The grinding component stops rotating, causing the placement component to stop rotating as well. Simultaneously, the operating component disengages from the outer support component, which slides inward into the placement component, restoring the rubber ring 6 to its original shape. This allows for easy observation of the grinding status of the outer ring of the rubber ring 6. If the grinding is satisfactory, the rubber ring 6 can be removed directly. If the grinding is unsatisfactory, the operating component is moved downward to re-grind the rubber ring 6 until it is ground to the desired state, at which point the rubber ring 6 can be removed.

[0031] For details, please refer to Figure 1-3 , Figure 6-8 , Figure 10 The placement assembly includes a second rotating rod 4, the bottom end of which is rotatably connected to the bottom end of the body 1, the top end of which penetrates the upper end of the body 1, and a placement plate 5 is horizontally fixed to the top end of the second rotating rod 4. A support groove 501 is provided on the side of the placement plate 5, and multiple sets of first sliding grooves 503 are horizontally provided on the inner wall of the support groove 501. The outer support assembly slides in cooperation with the first sliding grooves 503, and a second sliding groove 504 is vertically provided at the top end of the placement plate 5.

[0032] For further details, please refer to Figure 1-3 , Figure 7-12The external support assembly includes a support block 7, the side of which is slidably engaged with a first sliding groove 503. A second sliding rod 8 is slidably engaged within a second sliding groove 504, with its bottom end elastically connected to the second sliding groove 504. The top end of the second sliding rod 8 extends out of the second sliding groove 504 and is in movable contact with an operating component. A second guide block 801 is vertically fixed to the outside of the second sliding rod 8. A second guide groove 505 is vertically formed on the side wall of the second sliding groove 504, with the second guide block 801 slidably engaged with the second guide groove 505. A third sliding groove 505 is horizontally formed at the bottom of the second sliding groove 504. 6. The third sliding groove 506 is connected to the support groove 501. A first sliding rod 701 is slidably fitted in the third sliding groove 506. The first sliding rod 701 extends into the support groove 501 and is fixedly connected to the support block 7. When the second sliding rod 8 moves downward along the second sliding groove 504, it drives the first sliding rod 701 to slide outward along the third sliding groove 506, and drives the support block 7 to slide outward along the first sliding groove 503. A pressing component for pressing the rubber ring 6 is movably arranged in the support block 7. The pressing component is in movable contact with the upper end of the rubber ring 6. When the support block 7 slides outward in the support groove 501, the pressing component slides outward from the support block 7.

[0033] In actual use, initially, the support block 7 is completely within the support groove 501, and the second sliding rod 8 is not in contact with the operating component. When it is necessary to polish the rubber ring 6, the rubber ring 6 is placed on the mounting plate 5, and the operating component is pressed down, which drives the second sliding rod 8 to move downward along the second sliding groove 504, drives the first sliding rod 701 to slide outward along the third sliding groove 506, and drives the support block 7 to slide outward along the first sliding groove 503. At this time, the support block 7 opens and fixes the rubber ring 6 outward, so that the rubber ring 6 is in close contact with the polishing component, and the polishing component can polish the outer ring of the rubber ring 6. After polishing is completed, the operating component is moved upward, and the second sliding rod 8 slides upward along the second sliding groove 504 under the elastic action, which drives the first sliding rod 701 to slide inward along the third sliding groove 506, and drives the support block 7 to slide inward along the first sliding groove 503, contacting the support block 7 to open and fix the rubber ring 6, making it easy to remove the rubber ring 6.

[0034] For further details, please refer to Figure 1-3 , Figure 7-12The support block 7 has a fourth sliding groove 702 horizontally opened at its upper end. The pressing assembly includes a pressure plate 703, which slides in cooperation with the fourth sliding groove 702. A third rotating rod 9 is horizontally arranged inside the support block 7 near the pressure plate 703. Both ends of the third rotating rod 9 are rotatably connected to the two inner side walls of the support block 7. A first gear 901 is fixed in the middle of the third rotating rod 9. A second tooth block 704 is fixed at the lower end of the pressure plate 703. The first gear 901 and the second tooth block 704 mesh and drive each other. A third pulley 902 is fixedly connected to both sides of the third rotating rod 9 on the first gear 901. The support block 7 has a third pulley 902 fixedly connected to the first gear 901 on both sides. A fourth rotating rod 10 is horizontally rotatable on one side of the plate 5. Both ends of the fourth rotating rod 10 are rotatably connected to the two inner side walls of the support block 7. A second gear 1001 is fixed in the middle of the fourth rotating rod 10. A first tooth block 502 is fixed at the bottom of the support groove 501. The second gear 1001 meshes with the first tooth block 502 for transmission. A fourth pulley 1002 is fixed on both sides of the fourth rotating rod 10 at the second gear 1001. The third pulley 902 and the fourth pulley 1002 are connected by a second transmission belt 903. When the support block 7 slides outward from the support groove 501, it drives the pressure plate 703 to slide outward from the fourth sliding groove 702.

[0035] In actual use, initially, the pressure plate 703 is completely located within the fourth sliding groove 702. When grinding is required on the rubber ring 6, the support block 7 slides outward from the support groove 501, driving the second gear 1001 to rotate, which in turn drives the fourth rotating rod 10 to rotate, which in turn drives the fourth pulley 1002 to rotate. Through the second transmission belt 903, the third pulley 902 rotates, which in turn drives the first gear 901 to rotate, causing the pressure plate 703 to slide outward along the fourth sliding groove 702. At this time, the pressure plate 703 presses down on the upper end of the rubber ring 6 to prevent the rubber ring 6 from being damaged due to friction during grinding. The force causes the support block 7 to jump up and down, resulting in uneven grinding. After grinding is completed, the support block 7 slides into the support groove 501, which drives the second gear 1001 to rotate in the opposite direction, drives the fourth rotating rod 10 to rotate in the opposite direction, drives the fourth pulley 1002 to rotate in the opposite direction, drives the third pulley 902 to rotate in the opposite direction through the second transmission belt 903, drives the first gear 901 to rotate in the opposite direction, and drives the pressure plate 703 to slide inward along the fourth sliding groove 702 until the pressure plate 703 slides completely into the fourth sliding groove 702, releasing the pressure of the pressure plate 703 on the rubber ring 6, making it easy to remove the rubber ring 6.

[0036] For further details, please refer to Figure 1-4The right-angle bracket 2 has a switch slot 201 at one end near the grinding component. The switch component includes a switch 11, which slides in the switch slot 201. The top of the switch 11 is in contact with the operating component. An upper contact plate 1101 is fixed to the bottom of the switch 11. The switch 11 is elastically connected to the bottom of the switch slot 201. A lower contact plate 202 is fixed to the bottom of the switch slot 201. The upper contact plate 1101 and the lower contact plate 202 are in contact. When the upper contact plate 1101 moves downward and contacts the lower contact plate 202, the switch is closed. The switch 11 is electrically connected to the grinding component through a control circuit. This is prior art and will not be described in detail here.

[0037] In actual use, initially, the upper contact plate 1101 is above the lower contact plate 202 and not in contact, and the switch is in the off state. When it is necessary to polish the rubber ring 6, the operating component is moved downward, causing the operating component to press the switch 11 downward, driving the switch 11 to move downward until the upper contact plate 1101 and the lower contact plate 202 come into contact with each other. At this time, the switch 11 is closed, driving the polishing component to rotate. After polishing is completed, the operating component is moved upward, and the switch 11 moves upward under the elastic action, and the upper contact plate 1101 and the lower contact plate 202 disengage. At this time, the switch 11 is turned off, and the polishing component stops rotating, preventing the operator from accidentally touching the rotating polishing component when replacing the rubber ring 6, which could cause injury to the operator.

[0038] For further details, please refer to Figure 1-3 , Figure 5 , Figure 10 The right-angle bracket 2 has a vertical through hole 203 at its top end near the placement component. The operating component includes a horizontal plate 12. The lower end of the horizontal plate 12 near the switch 11 is in movable contact with the switch 11. A third sliding rod 1201 is fixed to the lower end of the horizontal plate 12 near the through hole 203. The third sliding rod 1201 slides in cooperation with the through hole 203. A first guide groove 204 is vertically formed on the side wall of the through hole 203. A third sliding rod 1201 is vertically fixed on the side wall of the third sliding rod 1201. The first guide block 1202 is slidably engaged with the first guide groove 024. The lower end of the third sliding rod 1201 is elastically connected to the right-angle bracket 2. The bottom end of the third sliding rod 1201 is vertically rotatably connected to a rotating block 1203. The lower end of the rotating block 1203 is in movable contact with the upper end of the second sliding rod 8. When the horizontal plate 12 moves downward, the horizontal plate 12 presses against the top end of the switch 11, and at the same time drives the rotating block 1203 to move downward to press against the second sliding rod 8.

[0039] In actual use, initially, the horizontal plate 12 is above the switch 11 and not in contact, and the rotating block 1203 is above the second sliding rod 8 and not in contact. When the rubber ring 6 needs to be polished, the horizontal plate 12 is pressed down, causing the third sliding rod 1201 to slide down until the rotating block 1203 presses down on the second sliding rod 8. At the same time, the horizontal plate 12 presses down on the switch 11, causing the upper contact plate 1101 and the lower contact plate 202 to contact each other, the switch 11 closes, the polishing assembly drives the mounting plate 5 to rotate, drives the second sliding rod 8 to rotate, and drives the rotating block 1203 to rotate, reducing the friction between the upper end of the second sliding rod 8 and the third sliding rod 1201 when rotating. After polishing is completed, the horizontal plate 12 is released, the third sliding rod 1201 moves upward under the elastic action, driving the horizontal plate 12 to move upward, the switch 11 to move upward, the upper contact plate 1101 and the lower contact plate 202 to disengage, and at the same time, the rotating block 1203 moves upward, disengaging from the second sliding rod 8.

[0040] For further details, please refer to Figure 1 , Figure 3 , Figure 6 The polishing assembly includes a first rotating rod 3, the bottom end of which is rotatably connected to the bottom end of the machine body 1, the top end of which passes through the upper end of the machine body 1, and a polishing roller 302 is vertically fixed at the upper end of the first rotating rod 3. The top end of the polishing roller 302 is rotatably connected to the bracket 2, and the polishing roller 302 is electrically connected to the switch 11. When the switch 11 is closed, the polishing roller 302 rotates.

[0041] For further details, please refer to Figure 1 , Figure 3 , Figure 6 The lower end of the first rotating rod 3 is horizontally fixed to one side inside the machine body 1 with a first pulley 301, and the lower end of the second rotating rod 4 is horizontally fixed to one side inside the machine body 1 with a second pulley 401. The first pulley 301 and the second pulley 401 are connected by a first transmission belt 402.

[0042] In actual use, in the initial state, switch 11 is in the off state, and both the grinding roller 302 and the mounting plate 5 are stationary. When switch 11 is closed, the grinding roller 302 rotates, which drives the first rotating rod 3 to rotate, which drives the first pulley 301 to rotate. Through the first transmission belt 402, the second pulley 401 rotates, which drives the second rotating rod 4 to rotate, which drives the mounting plate 5 to rotate, and drives the rubber ring 6 to rotate. At this time, the grinding roller 302 and the rubber ring 6 rotate in the same direction, which facilitates multi-angle grinding of the rubber ring 6.
