Description

A burr trimming device for rubber sealing parts

Technical Field

The invention relates to the technical field of sealing ring production, in particular to a burr trimming device for a rubber sealing piece.

Background Art

Rubber sealing rings are usually manufactured using an injection molding process. After the injection molding is completed, the burrs (i.e., the mold line) on the rubber sealing ring blank need to be removed to prevent the burrs from affecting the sealing performance of the rubber sealing ring.

After searching, a Chinese patent with publication number: CN219028190U discloses a deburring device for a sealing ring, including a driving wheel with a horizontal axis and a pressure wheel located directly above the driving wheel, a V-shaped groove is provided on the side wall of the driving wheel, the shape of the side wall of the pressure wheel is adapted to the groove, and the pressure wheel can move vertically; two semi-rings, semi-annular blades are arranged in the semi-rings, the two semi-rings can be opened and closed, and the two semi-rings after closing form a cutting ring, and the height of the cutting ring is consistent with the highest point height of the groove of the driving wheel.

Based on the above search and combined with actual problems, it was found that: the device drives the sealing ring to move past the cutting blade through the traction wheel to achieve the removal of the burrs on the surface of the sealing ring, but in actual use, it is difficult to control the distance between the cutting blade and the burrs of the sealing ring, and the sealing ring will produce a large swing when moving quickly, resulting in the distance between the cutting blade and the burrs of the sealing ring always being in a changing state. If the cutting blade is too far away from the sealing ring, some burrs cannot be completely removed. If the distance is too close, the rubber of the sealing ring body will be cut, resulting in a gap on the surface of the sealing ring, affecting the production quality of the sealing ring and increasing the defective rate.

Furthermore, the centering clamping mechanism includes a cylinder 201 installed at the middle position of the lower side of the support plate 4, two pins 203 fixed to one end of the lower side of the first arc-shaped slider 6 and the second arc-shaped slider 7, a push rod 202 is fixed to the telescopic end of the cylinder 201, and two slide plates 204 are symmetrically fixed at both ends of the push rod 202 at one side, and the insides of the two slide plates 204 are both provided with oblique slides 205, and the two pins 203 are respectively slidably connected to the inner sides of the two oblique slides 205;

Through the centering clamping mechanism, the four grinding rollers 103 can be pressed against the inner and outer sides of the sealing ring respectively, so that the inner and outer sides of the sealing ring can be subjected to the same pressure from the grinding rollers 103, which is beneficial to improving the consistency of the burr grinding on the inner and outer sides, thereby avoiding deformation of the sealing ring surface.

Multiple fitting shaping wheels 114 can press the inner and outer sides of the sealing ring. When the burr grinding mechanism moves back and forth in an arc, multiple fitting shaping wheels 114 can roll along the inner and outer sides of the sealing ring to prevent the sealing ring from being squeezed and deformed by the edging roller 103, thereby improving the grinding uniformity of the sealing ring.

Furthermore, a cleaning wheel 117 is fixed to the outer side of the transmission shaft 105, and a plurality of cleaning scrapers 118 arranged in a circumference are elastically connected to the outer side of the cleaning wheel 117, and the height of the cleaning wheel 117 is equal to the height of the two edge grinding rollers 103 on both sides;

When the transmission shaft 105 rotates, the cleaning wheel 117 and the cleaning scraper 118 are driven to rotate. The cleaning scraper 118 can sweep away the powder generated by grinding the outer side of the sealing ring to prevent the powder from adhering to the surface of the sealing ring to reduce friction and affect the grinding effect.

Further, the transmission belt 110 is an elastic belt, and the cross section of the transmission belt 110 is circular;

The transmission belt 110 can be stretched. When the first arc-shaped slider 6 and the second arc-shaped slider 7 drive the driving pulley 107 to move, the transmission belt 110 can be tightened to improve the transmission stability and avoid slipping between the transmission belt 110 and the driving pulley 107, thereby driving the edging roller 103 to rotate smoothly and evenly grind the sealing ring.

Furthermore, the sealing ring fixing mechanism includes an outer fixing ring 306 fixed on the upper side of the truncated table 1 at the edge position, four circumferentially arranged supporting poles 301 fixed on the upper side of the truncated table 1 at the edge position, the four supporting poles 301 and the four supporting cross bars 3 are arranged alternately, and the upper ends of the four supporting poles 301 are rotatably connected to the upper supporting arms 304, and the lower ends of the four supporting poles 301 are fixed to the lower arms 302, and the four lower supporting arms 302 and One end of each of the four upper arms 304 is fixed with a sealing ring clamp 303, and the other ends of each of the four upper arms 304 are rotatably connected with an intermediate connecting rod 305, the inner upper end of the outer fixed ring 306 is slidably connected with an inner movable ring 307, the upper end of the inner movable ring 307 is fixed with a top ring 308, the lower end of the top ring 308 is connected with a tightening spring 309 sleeved on the outer side of the inner movable ring 307, and one end of each of the four intermediate connecting rods 305 is rotatably connected with the upper side of the top ring 308;

The sealing ring fixing mechanism can fix the sealing ring that needs to be trimmed, and at the same time provide uniform support for the sealing ring to prevent the sealing ring from shifting during trimming, which is conducive to the four burr grinding mechanisms to move stably along the outside of the sealing ring, further improving the trimming effect of the sealing ring burr and improving the production quality of the sealing ring.

Furthermore, one side of the plurality of sealing ring clamps 303 is provided with an arc surface adapted to the outer surface of the sealing ring, and the plurality of sealing ring clamps 303 are all made of rubber material;

The sealing ring clamp 303 can be made to fit better with the outer side of the sealing ring and provide greater friction to avoid the sealing ring from being deformed by compression, while improving the fixing stability of the sealing ring, preventing the sealing ring from loosening, and improving the grinding accuracy of the burrs of the sealing ring.

Working principle: When in use, first press the top ring 308 and the inner movable ring 307, the top ring 308 compresses the holding spring 309, the top ring 308 moves downward and pulls the four upper arms 304 to rotate through the four intermediate connecting rods 305, so that the sealing ring clamps 303 at one end of the four upper arms 304 are flipped upward, and then the newly injection-molded sealing ring is placed on the upper side of the four sealing ring clamps 303 located below the sealing ring fixing mechanism, and then the top ring 308 is released. The top ring 308 moves upward and resets under the elastic force of the holding spring 309, and then drives the four upper arms 304 to reverse through the four intermediate connecting rods 305. Rotate to a horizontal angle to reset, so that the four sealing ring clamps 303 located on the top are pressed on the upper side of the sealing ring, and the sealing ring is pressed tightly on the upper side of the four sealing ring clamps 303 below. Since one side of the plurality of sealing ring clamps 303 is provided with an arc surface adapted to the outer surface of the sealing ring, and the plurality of sealing ring clamps 303 are made of rubber material, the sealing ring clamps 303 can be better fitted with the outer side of the sealing ring, and provide greater friction, avoid the sealing ring from being deformed by compression, and at the same time improve the fixing stability of the sealing ring, prevent the sealing ring from loosening, and improve the grinding accuracy of the burrs of the sealing ring;

Then, the telescopic ends of the four cylinders 201 of the four centering clamping mechanisms are respectively controlled to extend, and the extension of the telescopic ends of the cylinders 201 drives the push rod 202 to move, and the push rod 202 drives the two slide plates 204 to move, and through the sliding connection cooperation between the inclined slide grooves 205 and the pin shafts 203, under the guiding action of the two inclined slide grooves 205, the two pin shafts 203 can be driven to move to the middle section position of the support plate 4 at the same time, thereby driving the first arc slide block 6 and the second arc slide block 7 to move to the middle section position of the support plate 4, and the first arc slide block 6 and the second arc slide block 7 respectively drive the four C-shaped frames 101 on the upper side to move toward the position of the sealing ring, thereby driving the four edge grinding rollers 103 to move synchronously toward the position of the sealing ring, so that the four edge grinding rollers 103 can be respectively pressed against the inner and outer sides of the sealing ring, so that the inner and outer sides of the sealing ring can be subjected to the same pressure from the edge grinding rollers 103, which is conducive to improving the consistency of the burr grinding on the inner and outer sides, thereby avoiding deformation of the surface of the sealing ring;

Then, the main motor 401 of the swing drive mechanism is controlled to drive the swing arm 402 to rotate, and the swing arm 402 drives the sliding pin 403 to rotate. Through the sliding connection between the sliding pin 403 and the swing arm slide groove 405, when the sliding pin 403 rotates continuously around the rotating shaft of the main motor 401, the swing arm 404 can be driven to swing back and forth, and the swing arm 404 drives the central rotating shaft 2 to swing back and forth. The central rotating shaft 2 drives the four supporting plates 4 to rotate forward and reverse around the central rotating shaft 2 through the four supporting cross bars 3, thereby driving the four first arc-shaped sliders 6 and the four second arc-shaped sliders 7 to rotate forward and reverse around the central rotating shaft 2. The first arc-shaped slider 6 and the second arc-shaped slider 7 drive the four C-shaped frames 101 and the transmission shaft 105 of the burr grinding mechanism to make arc-shaped reciprocating movements around the outer side of the sealing ring. Since the two ends of the transmission belt 110 are fixed to the two fixed sleeves 112, when the transmission shaft 105 drives the driving pulley 107 to move in an arc, the transmission belt 110 can drive the driving pulley 107 to rotate, and the driving pulley 107 drives the intermediate pulley 106 to rotate. The intermediate pulley 106 drives the two upper pulleys 104 on the outer side to rotate synchronously through the two first synchronous belts 113, and the two upper pulleys 104 on the outer side respectively drive the outer pulleys 107 to rotate synchronously. The two side follower shafts 102 rotate, and the two outer follower shafts 102 drive the two outer grinding rollers 103 to rotate and drive the two outer lower end pulleys 115 to rotate. Since each second synchronous belt 116 is made of elastic material, the second synchronous belt 116 can always maintain friction with the lower end pulley 115. Therefore, the two outer lower end pulleys 115 drive the two inner lower end pulleys 115 to rotate through the two second synchronous belts 116, thereby driving the two inner follower shafts 102 to rotate, and the two inner follower shafts 102 drive the two inner grinding rollers 103 Rotate, so that the four edge grinding rollers 103 located inside and outside the sealing ring can rotate synchronously at high speed. When the first arc-shaped slider 6 and the second arc-shaped slider 7 make arc-shaped reciprocating movements around the central rotating shaft 2, the four edge grinding rollers 103 can grind the burrs on both sides of the inside and outside of the sealing ring. The four burr grinding mechanisms can simultaneously grind and remove the burrs at various positions on the outside of the sealing ring, which plays a role in trimming the burrs. The grinding is more uniform, which can avoid excessive wear on the sealing ring body, so that the cross section of the sealing ring can maintain a complete circle, reduce the generation of defective products, and improve the production quality of the sealing ring;

Since the outer ends of the four follower shafts 102 are located at both sides of the edging roller 103 and are symmetrically connected to two fitting shaping wheels 114, the outer side of each fitting shaping wheel 114 is provided with a curved surface that matches the outer side of the sealing ring. The multiple fitting shaping wheels 114 can press the inner and outer sides of the sealing ring. When the burr grinding mechanism moves back and forth in an arc, the multiple fitting shaping wheels 114 can roll along the inner and outer sides of the sealing ring to prevent the sealing ring from being squeezed and deformed by the edging roller 103, thereby improving the grinding uniformity of the sealing ring. When the transmission shaft 105 rotates, it drives the cleaning wheel 117 and the cleaning scraper 118 to rotate. The cleaning scraper 118 can sweep away the powder generated by grinding the outer side of the sealing ring to prevent the powder from adhering to the surface of the sealing ring to reduce friction and affect the grinding effect.
