Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a polishing equipment for the inner cavity of a cylinder used for filter processing. Background Art

[0002] With the rapid development of industry, the quality of parts is getting higher and higher. Many parts need to be polished to change the surface roughness after processing. Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of parts to obtain a bright and flat surface. It is a processing method that uses polishing tools and polishing media to process the surface of parts. The purpose is to obtain a smooth surface or mirror gloss. Sometimes it is also used to eliminate gloss. The inner wall polishing operation of cylindrical products is usually a key process that affects product quality. After years of development, the domestic cylindrical inner wall polishing operation has developed two main polishing methods: polishing machines and cantilever polishing arms. It is gradually developing in the direction of intelligence and diversification, and the equipment and devices for polishing operations are becoming more and more diverse.

[0003] Some existing polishing equipment has certain limitations when processing the inner wall of the cylinder. The contact between the polishing tool and the inner wall of the cylinder is uneven, resulting in unsatisfactory polishing effect, inconsistent surface roughness, substandard flatness and other problems. In addition, the polishing equipment is difficult to adapt to cylinders of different sizes and shapes, and the tooling fixtures need to be replaced frequently, which makes the operation complicated and costly. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A filter processing cylinder inner cavity polishing device includes a platform, the top front end of the platform is fixedly connected to a control box;

[0005] Support assembly, the support assembly is fixedly installed on the top of the platform;

[0006] Pressure assembly, the pressure assembly is installed on the rear end side of the platform;

[0007] Positioning assembly, the positioning assembly is fixedly installed on the side of the platform close to one end of the supporting assembly;

[0008] A grinding assembly is installed at one end of the platform away from the supporting assembly;

[0009] The grinding assembly includes a moving block, a side of the moving block close to the supporting assembly is fixedly connected to an intermediate rod, and an end of the intermediate rod away from the moving block is fixedly connected to a grinding piece;

[0010] The U-shaped frame is slidably connected to the inner wall of the ring groove, and the middle part of the U-shaped frame is located inside the ring groove. The middle part of the U-shaped frame is magnetic, and the magnetism between the two U-shaped frames is opposite. The cylinder to be processed is placed between the two supporting rollers. The two supporting rollers support the cylinder in the middle. The hydraulic cylinder drives the limit seat to move downward, so that the limit seat drives the bottom pressure roller to move downward, so that the pressure roller contacts the outer side of the top of the cylinder, thereby limiting the cylinder in the vertical direction, and the slider moves upward on the slide rail. The slider moves in the direction of the cylinder, driving the middle rod and the grinding piece to move through the gantry. At this time, the round block and the grinding roller are located inside the cylinder. The mutual repulsion of the two U-shaped frames is used to drive the grinding roller close to the inner wall of the cylinder, so that the grinding roller is in close contact with the inner wall of the cylinder. By symmetrically arranging the two grinding rollers, local over- or under-polishing caused by single-point grinding is avoided, ensuring the consistency of surface roughness, and can be adapted to cylinders of different inner diameters without replacing the entire grinding device. The open end of the U-shaped frame is rotatably connected to the grinding roller, and the outer side of the U-shaped frame is fixedly connected to a motor, and the output end of the motor is fixedly connected to the grinding roller.

[0011] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry mobile handler location.

[0012] Preferably, a through hole is provided inside the round block, and there are two through holes. The two through holes are symmetrically arranged on the round block, and the inner wall of the through hole is slidably connected with a connecting block. The connecting block is trapezoidal in design, and the hypotenuse of the connecting block is arranged parallel to the hypotenuse of the trapezoidal block. The connecting block is magnetic, and the magnetism between the two connecting blocks is the same, and the magnetism of the connecting block and the U-shaped frame is the same. The connecting block and the grinding roller are arranged alternately, and an air suction hole is provided inside the connecting block, and the air suction hole is connected to the air suction end of the exhaust fan through the inner cavity. During the polishing process, the U-shaped frame moves inside the annular groove, so that the grinding roller contacts the inner wall of the cylinder, and the U-shaped frame drives the trapezoidal block to move through the arc plate. Due to the mutual repulsion between the two connecting blocks, the connecting blocks are close to the inside of the cylinder. By adjusting the spacing, the suction hole and the inner wall of the cylinder can maintain the optimal negative pressure action distance. At close distances, the adsorption force is enhanced, and large particles of debris are quickly sucked out. Due to the debris, dust and oil generated during the polishing process, the exhaust fan works to generate negative pressure at the suction holes on the connecting blocks, thereby adsorbing the waste chips on the inner wall of the cylinder, preventing these impurities from remaining on the inner wall of the cylinder or secondary attachment, avoiding scratches on the inner wall surface, ensuring the smoothness and accuracy of the polished cylinder surface, and reducing the diffusion of dust in the air during processing, reducing the risk of operators inhaling harmful particles The U-shaped frame is fixedly connected to the outside of one end of the grinding roller with an L-shaped plate, and the L-shaped plate is symmetrically arranged with the U-shaped frame as the center. The U-shaped frame is fixedly connected to the outside of the grinding roller close to the grinding roller with an arc plate, and the arc plate is arranged perpendicular to the L-shaped plate. There are multiple arc plates, and the multiple arc plates are evenly and symmetrically arranged on both sides of the U-shaped frame. The two arc plates on one side of the U-shaped frame are symmetrically arranged with the L-shaped plate as the center. The arc plate is fixedly connected to the end of the U-shaped frame away from the U-shaped frame with a trapezoidal block, and the two ends of the trapezoidal block are fixed to the two arc plates at both ends of the round block. Fixed connection, the arc plate is connected to the side of the grinding roller for rotation with a cleaning roller. The residual debris and abrasive will aggravate the wear of the surface of the grinding roller. By setting the cleaning roller, the impurities on the grinding roller are cleaned to prevent uneven grinding, surface scratches and other problems caused by the adhesion of impurities. Ensure that the grinding roller always works in the best condition, stably outputs high-quality grinding effects, and reduces the friction loss between the grinding roller and impurities, effectively extending the service life of the grinding roller and reducing the frequency and cost of replacing equipment consumables. The two ends of the cleaning roller are connected to the two arc plates located at both ends of the round block. There are two cleaning rollers, and the two cleaning rollers are symmetrically arranged with the grinding roller as the center.

[0013] Preferably, the protective assembly includes a circular ring, which is slidably connected to the middle rod, the circular ring is sleeved on the outer side of the middle rod, and the inner wall of the circular ring is fixedly connected to a limit block. There are multiple limit blocks, and the multiple limit blocks are evenly distributed inside the circular ring. The limit block is located inside the slide groove. In the initial state, the circular block and the grinding roller are located inside the protective cylinder. At this time, the grinding roller contacts the inner wall of the protective cylinder. After the cylinder is installed, the slider drives the gantry and the middle rod close to the cylinder, so that the limit plate contacts the inner wall of the cylinder and generates extrusion. When the limit plate is affected Under the action of the extrusion force, the ring drives the protective tube to slide on the outside of the middle rod, so that the limit block slides inside the slide groove, and the mutual sliding adaptation between the limit block and the slide groove plays a guiding role. At this time, as the slider drives the middle rod to continue to move, the spring plate is stretched by force, and the grinding roller breaks away from the protective tube and moves along the extension tube to the inside of the cylinder. Then, the mutual repulsion of the U-shaped frame is used to drive the grinding roller to move on the inner wall of the ring groove in the direction away from the middle rod, so that the grinding roller contacts the inner wall of the cylinder, and the grinding roller is tilted. The limit plate provided can automatically guide the grinding piece to the middle of the cylinder by means of an inclined guide, thereby forming a stable center positioning. This avoids the problem of uneven force on the grinding piece caused by placement offset, ensures uniform contact between the cylinder and all parts of the grinding piece, greatly improves the consistency of surface accuracy after grinding, reduces the scrap rate, and ensures that the roundness error can be controlled within an extremely small range. In addition, during the rotational grinding process, the center of gravity of the grinding piece located in the middle of the cylinder is close to the central axis of the equipment, making the operation smoother and reducing the vibration and noise caused by the center of gravity offset, which not only helps to extend the service life of the grinding equipment and related components. A spring plate is fixedly connected to the outer side of the end of the ring close to the circular block, and the end of the spring plate away from the ring is fixedly connected to the circular block. There are multiple spring plates, and the multiple spring plates are evenly distributed around the ring. A fixing rod is fixedly connected to the outer side of the ring.

The side of the fixing rod close to the spring plate is fixedly connected to a protective tube, and the end of the protective tube away from the fixing rod is fixedly connected to an extension tube.

[0014] Preferably, the platform includes a support plate, the top of the support plate is fixedly connected to a slide rail, the slide rail is located at the end of the support plate away from the support assembly, the slide rail is slidably connected to the slider, there are two slide rails, a trapezoidal groove is provided on the top of the support plate close to the support assembly, there are four trapezoidal grooves, the inner wall of the trapezoidal groove is fixedly connected to a positioning plate, the positioning plate is arranged parallel to the hypotenuse of the trapezoidal groove.

The hydraulic cylinder drives the limit seat to move downward, so that the limit seat drives the bottom pressure roller to move downward, so that the pressure roller contacts the outer side of the top of the cylinder. At this time, the pressure roller and the two support rollers at the bottom form a triangular clamping structure, which effectively limits the axial and radial displacement and rotation of the cylinder, avoiding surface accuracy deviation caused by shaking during polishing or processing. At the same time, by adjusting the height of the pressure roller and the spacing between the bottom support rollers, it can adapt to cylinders of different sizes, and the surfaces of the pressure roller and the support roller are wrapped with elastic material to reduce the risk of scratches on the surface of the cylinder by rigid contact. The output end of the hydraulic cylinder passes through the extension plate, and the output end of the hydraulic cylinder is fixedly connected to the limit seat. The inner wall of the limit seat is rotatably connected to the pressure roller, and the outer side of the limit seat is fixedly connected to a drive motor, which is fixedly connected to the pressure roller.

[0016] The cam is fixedly connected to the outer side of the support plate, and the outer side of the support plate is fixedly connected to the electric push rod, the output end of the electric push rod passes through the vertical plate, and the output end of the electric push rod is fixedly connected to the pressure plate. When the electric push rod works, it pushes the pressure plate to contact one end of the cylinder along the sliding rod, fixing one end of the cylinder to form a stable reference point, effectively limiting its axial movement, ensuring that the position does not deviate during the grinding process, so that the cylinder remains stable during the grinding process. When the grinding roller moves along the inner wall toward the pressure plate, the reaction force provided by the fixed end ensures that the grinding pressure is evenly transmitted to the entire inner wall, avoiding uneven surface roughness caused by shaking of the cylinder, and making the cylinder uniformly stressed during the grinding process, avoiding stress concentration problems caused by fixing at both ends, which can effectively prevent deformation caused by excessive constraint and ensure the structural integrity and dimensional accuracy of the workpiece. The pressure plate is fixedly connected to a sliding rod on one side near the vertical plate, and the sliding rod is slidably connected to the vertical plate. There are two sliding rods, and the two sliding rods are symmetrically arranged at both ends of the sliding rod.

[0017] Material toggling mechanism, its both ends are connected with the support of the support frame, and the support frame has the outermost layer of sliding block, and the inner layer of sliding block is connected with the support frame of the support frame. By adjusting the distance between the two support rollers, it can adapt to cylindrical workpieces of different diameters and lengths. No matter it is small-diameter precision pipe fittings or large-diameter industrial storage tanks, it can provide stable support, avoiding the need to replace special support equipment due to differences in workpiece specifications, reducing equipment procurement costs, improving equipment utilization, and meeting diversified production needs. The end of the connecting rod away from the sliding block is rotatably connected to a rotating rod, and the middle of the rotating rod is fixedly connected to an arc plate. The four sliding blocks are divided into two groups, and the sliding blocks of the two groups are symmetrically arranged at both ends of the arc plate. The two sliding blocks in one group are symmetrically arranged with the arc plate as the center, and the support rollers are symmetrically arranged with the arc plate as the center. A positioning rod is fixedly connected to the bottom of one end of the arc plate, and the positioning rod is slidably connected to the support plate. A spring is provided on the outer side of the positioning rod, and the two ends of the spring are fixedly connected to the arc plate and the support plate respectively.

[0018] The present invention provides a filter cylinder inner cavity polishing device. It has the following beneficial effects:

[0019] 1. The filter cylinder inner cavity polishing equipment utilizes the mutual repulsion of two U-shaped frames to drive the grinding roller close to the inner wall of the cylinder, so that the grinding roller is in close contact with the inner wall of the cylinder. By symmetrically arranging the two grinding rollers, local over-polishing or under-polishing caused by single-point grinding is avoided, ensuring the consistency of surface roughness. It can also adapt to cylinders with different inner diameters without replacing the entire set of grinding equipment.

[0020] 2. The inner cavity polishing equipment of the cylinder used in the filter processing works by means of an exhaust fan, which creates a negative pressure at the air intake holes on the connecting block, thereby adsorbing the waste chips on the inner wall of the cylinder, preventing these impurities from remaining on the inner wall of the cylinder or attaching to it for the second time, and avoiding scratching the inner wall surface, thereby ensuring the smoothness and precision of the cylinder surface after polishing, and reducing the diffusion of dust in the air during the processing process.

[0021] 3. The polishing equipment for the inner cavity of the cylinder processed by the filter uses the mutual repulsion between the two connecting blocks. The connecting blocks are close to the inside of the cylinder. By adjusting the spacing, the suction hole and the inner wall of the cylinder can maintain the optimal negative pressure action distance, which enhances the adsorption force at close distance and quickly absorbs large particles of debris.

[0022] Fourth, the inner cavity polishing equipment of the filter cylinder can automatically guide the polishing part to the middle of the cylinder by using the inclined guide, forming a stable center positioning. This avoids the problem of uneven force on the polishing part due to placement offset, ensures uniform contact between the cylinder and the polishing part, greatly improves the consistency of the surface accuracy after polishing, reduces the scrap rate, and ensures that the roundness error can be controlled within a very small range.

The support plate 41 is fixedly connected to an extension plate near the top of the support plate 11, and the top of the extension plate is fixedly connected to a hydraulic cylinder 42. The cylinder to be processed is placed in the middle of the two support rollers 23. The two support rollers 23 support the cylinder in the middle. The hydraulic cylinder 42 drives the limit seat 43 to move downward, so that the limit seat 43 drives the bottom pressure roller 44 to move downward, so that the pressure roller 44 contacts the outer side of the top of the cylinder. At this time, the pressure roller 44 and the two support rollers 23 at the bottom form a triangular clamping structure, which effectively limits the axis of the cylinder The hydraulic cylinder 42 is provided with a plurality of support rollers 23, and the support rollers 23 are provided with a plurality of support rollers 24. The support rollers 23 are provided with a plurality of support rollers 24. The support rollers 23 are provided with a plurality of support rollers 24.

The output end of the electric push rod 52 is fixedly connected to a pressure plate 53. The electric push rod 52 works, thereby pushing the pressure plate 53 along the slide rod 54 to contact one end of the cylinder, fixing one end of the cylinder to form a stable reference point, effectively limiting its axial movement, ensuring that the position does not deviate during the grinding process, and keeping the cylinder stable during the grinding process. The grinding roller 385 moves along the inner wall to the pressure plate When 53 moves, the reaction force provided by the fixed end ensures that the grinding pressure is evenly transmitted to the entire inner wall, avoiding uneven surface roughness caused by the shaking of the cylinder, and making the cylinder evenly stressed during the grinding process, avoiding the stress concentration problem caused by the fixation of both ends, and can effectively prevent deformation caused by excessive constraints, ensuring the structural integrity and dimensional accuracy of the workpiece. The side of the pressure plate 53 close to the vertical plate 51 is fixedly connected to a sliding rod 54, and the sliding rod 54 is slidably connected to the vertical plate 51. There are two sliding rods 54, and the two sliding rods 54 are symmetrically arranged at both ends of the sliding rod 54.

[0046] The third embodiment, based on the first and second embodiments, see Figures 7 and 8As shown, the support assembly 2 includes a sliding block 21, the number of which is four. The sliding block 21 is located inside the trapezoidal groove 13, and a through groove 22 is provided on the outside of the sliding block 21. The positioning plate 14 is located inside the through groove 22. The outside of the sliding block 21 is rotatably connected to a rotating shaft 24. The two ends of the rotating shaft 24 are rotatably connected to the two sliding blocks 21. A supporting roller 23 is fixedly connected to the middle of the outside of the rotating shaft 24. The number of supporting rollers 23 is two. The outside of the sliding block 21 is rotatably connected to a connecting rod 25. The cylinder to be processed is placed on the rotating shaft 24. In the middle of the two support rollers 23, the two support rollers 23 support the middle cylinder. Under the action of the gravity of the cylinder itself, the spring 27 is compressed, so that the positioning rod 28 drives the arc plate 26 to move downward. At the same time, the connecting action of the connecting rod 25 is used to make the connecting rod 25 push the sliding block 21 to move in the direction away from the arc plate 26 inside the trapezoidal groove 13. Then the hydraulic cylinder 42 works to drive the limit seat 43 to move downward, so that the limit seat 43 drives the bottom pressure roller 44 to move downward, so that the pressure roller 44 is aligned with the outer side of the top of the cylinder. Contact, and then by adjusting the distance between the two support rollers 23, it can adapt to cylindrical workpieces of different diameters and lengths. Whether it is a small-diameter precision pipe or a large-diameter industrial storage tank, it can be stably supported, avoiding the need to replace special support equipment due to differences in workpiece specifications, reducing equipment procurement costs, improving equipment utilization, and meeting diversified production needs. The end of the connecting rod 25 away from the sliding block 21 is rotatably connected to the rotating rod 29, and the middle part of the rotating rod 29 is fixedly connected to the arc plate 26. The four sliding blocks 21 are divided into two groups, and the sliding blocks of the two groups 21 is symmetrically arranged at both ends of the arc-shaped plate 26, the two sliding blocks 21 in a group are symmetrically arranged with the arc-shaped plate 26 as the center, the support roller 23 is symmetrically arranged with the arc-shaped plate 26 as the center, and a positioning rod 28 is fixedly connected to the bottom of one end of the arc-shaped plate 26. The positioning rod 28 is slidably connected to the support plate 11, and a spring 27 is sleeved on the outer side of the positioning rod 28. The two ends of the spring 27 are respectively fixedly connected to the arc-shaped plate 26 and the support plate 11. There are two positioning rods 28, and the two positioning rods 28 are symmetrically arranged with the arc-shaped plate 26 as the center.

[0047] When in use, the cylinder to be processed is placed between the two support rollers 23. The two support rollers 23 support the middle part of the cylinder. Under the action of the gravity of the cylinder itself, the spring 27 is compressed, so that the positioning rod 28 drives the arc plate 26 to move downward. At the same time, the connecting action of the connecting rod 25 is utilized to make the connecting rod 25 push the sliding block 21 to move inside the trapezoidal groove 13 in the direction away from the arc plate 26. The hydraulic cylinder 42 drives the limit seat 43 to move downward, so that the limit seat 43 drives the bottom pressure roller 44 to move downward, so that the pressure roller 44 contacts the outer side of the top of the cylinder, thereby limiting the vertical direction of the cylinder, and the electric push rod 52 works, thereby pushing the pressure plate 53 to contact one end of the cylinder along the slide rod 54, fixing one end of the cylinder.

[0048] After the cylinder is installed, the slider 31 drives the gantry 32 and the middle rod 311 close to the cylinder, so that the limit plate 396 contacts the inner wall of the cylinder and is squeezed. Under the action of the squeezing force exerted on the limit plate 396, the ring 391 drives the protective cylinder 394 to slide on the outside of the middle rod 311, so that the limit block 392 slides inside the slide groove 312, and the mutual sliding adaptation between the limit block 392 and the slide groove 312 plays a guiding role. At this time, as the slider 31 drives the middle rod 311 to continue to move, the spring plate 395 is stretched by force, and the grinding roller 385 separates from the protective cylinder 394 and moves along the extension cylinder 397 to the inside of the cylinder. Then, the mutual repulsion of the U-shaped frame 383 is used to drive the grinding roller 385 to move on the inner wall of the annular groove 382 in the direction away from the middle rod 311, thereby making the grinding roller 385 contact the inner wall of the cylinder.
