Abstract
Description
Technical Field
[0001] This invention relates to the field of ceramic sleeve processing technology, and in particular to a ceramic sleeve cutting system. Background Technology
[0002] Ceramic sleeves are tubular structural components made of ceramic materials, featuring high temperature resistance, corrosion resistance, and insulation. They are commonly used in electronic components, chemical equipment, and oil drilling equipment. Due to the properties of ceramic materials, ceramic sleeves typically exhibit excellent wear resistance and corrosion resistance.
[0003] In the production of ceramic sleeves, cutting is a crucial step. Current cutting processes are mainly divided into mechanical cutting and laser cutting.
[0004] In mechanical cutting processes, epoxy resin adhesive is used to fix the ceramic sleeve to be cut. After cutting, adhesive remover and processing cleaner are needed to remove the epoxy resin adhesive. These adhesive remover and processing cleaner are highly volatile and flammable chemicals, which can easily harm the health of workers, requiring significant protective measures.
[0005] In laser cutting, the high cost of laser processing equipment is a significant factor. Secondly, due to the susceptibility of ceramic materials to thermal phase transformation, excessively high temperatures during the cutting of ceramic sleeve ends can lead to severe carbonization, altering material properties. Furthermore, the cut end is prone to significant deformation, resulting in severe taper and burr issues, and noticeable dimensional changes after processing. For small-sized ceramic sleeves, laser cutting yields poor results, requiring secondary processing. Therefore, laser cutting of ceramic sleeves presents challenges due to high cost and low yield rates, hindering large-scale mass production. Although laser cutting improves efficiency, for ceramic sleeve products, especially smaller ones, significant processing defects remain, necessitating secondary repairs and failing to meet market demands for high-quality products. Summary of the Invention
[0006] The purpose of this invention is to at least partially solve one of the aforementioned technical problems.

The control magnet is rotatably located between the first magnet and the second magnet.
[0017] The N pole of the first magnet faces the second clamping surface of the lower clamping fixture, and the S pole of the first magnet faces away from the second clamping surface of the lower clamping fixture. The S pole of the second magnet faces the second clamping surface of the lower clamping fixture, and the N pole of the second magnet faces away from the second clamping surface of the lower clamping fixture. When the control magnet is rotated to a first rotation angle, the N pole of the control magnet faces the S pole of the first magnet, and the S pole of the control magnet faces the N pole of the second magnet. When the control magnet is rotated to a second rotation angle, the S pole of the control magnet faces the S pole of the first magnet, and the N pole of the control magnet faces the N pole of the second magnet.

The first pressing surface is provided with a plurality of convex surfaces arranged side by side in the second direction, and the second pressing surface is provided with a plurality of concave surfaces arranged side by side in the second direction. The plurality of convex surfaces are one-to-one opposite to the plurality of concave surfaces.
[0021] According to one embodiment of the present invention, a plurality of convex surfaces and a plurality of concave surfaces have a misalignment distance in the second direction.
[0022] According to one embodiment of the present invention, in the second direction, a plurality of magnetic linkage rods are arranged sequentially at intervals on both sides of the lower clamping fixture;
[0023] The electromagnetic magnetic attraction platform includes a placement groove, which contains multiple electromagnetic positioning points and an electromagnetic attraction surface. The placement groove is used to place the clamping fixture. The positions of the multiple electromagnetic positioning points correspond to the arrangement positions of the multiple magnetic linkage rods. When the clamping fixture is placed in the placement groove, the multiple electromagnetic positioning points and the multiple magnetic linkage rods are aligned one-to-one, and the electromagnetic attraction surface covers the bottom of the placement groove.

[0032] According to the cutting command, the displacement driving mechanism is controlled to drive the sleeve cutting machine to advance at a first cutting speed to cut the ceramic sleeve of the clamping fixture;
[0033] The motion trajectory sensed by the grating ruler is acquired, and the actual tolerance of the motion trajectory is calculated;
[0034] If the actual tolerance is greater than the preset tolerance, the sleeve cutting machine is driven to advance at the second cutting speed to cut the ceramic sleeve of the clamping fixture. The second cutting speed is less than the first cutting speed.

Detailed Implementation
[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of the present invention.
[0063] Traditional ceramic sleeve cutting processes, using mechanical methods, require the use of epoxy resin adhesive, adhesive remover, and processing cleaners, which can easily harm the health of workers. Laser cutting, on the other hand, involves expensive equipment. Therefore, this invention proposes a ceramic sleeve cutting system.
[0064] Specifically, the following description, with reference to the accompanying drawings, describes a ceramic sleeve cutting system according to an embodiment of the present invention.

Figure 2 This is a top view schematic diagram of a ceramic sleeve cutting system according to an embodiment of the present invention. Figure 3 This is a side view schematic diagram of a ceramic sleeve cutting system according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the clamping fixture of a ceramic sleeve cutting system according to an embodiment of the present invention. Figure 5 This is a top view schematic diagram of the clamping fixture of a ceramic sleeve cutting system according to an embodiment of the present invention. Figures 1 to 5 As shown, a ceramic sleeve cutting system includes: a clamping fixture and a processing platform 40.
[0066] The clamping fixture includes multiple upper clamping fixtures 10, a magnetically attached lower clamping fixture 20, and multiple magnetically attached linkage rods 30. The multiple upper clamping fixtures 10 are opposite to the lower clamping fixtures 20, arranged sequentially and side-by-side in a first direction to form a cutting interval between adjacent upper clamping fixtures 10. The first clamping surface 10a of the upper clamping fixture 10 and the second clamping surface 20a of the lower clamping fixture 20 are opposite to each other. The first clamping surface 10a has multiple first grooves 10b arranged sequentially and side-by-side in a second direction, each coated with a polyurethane coating. The first clamping surface 10a also has multiple second grooves 20b arranged sequentially and side-by-side in a second direction, each coated with a polyurethane coating. Each of the multiple first grooves 10b is opposite to each of the multiple second grooves 20b, forming a clamping space for the ceramic sleeve extending in the first direction between the polyurethane coatings 13 of the opposing first grooves and the polyurethane coatings 22 of the opposing second grooves. The second direction is perpendicular to the first direction. The lower clamping fixture 20 is provided with multiple first through holes 21, and multiple magnetic linkage rods 30 are movably disposed in the multiple first through holes 21 and connected to the upper clamping fixture 10. The processing platform 40 includes a placement platform 41, a sleeve cutting machine 42, and a displacement driving mechanism 43. The placement platform 41 is an electromagnetic magnetic platform used to place and magnetically attract the clamping fixture, and the sleeve cutting machine 42 is disposed on the displacement driving mechanism 43.
[0067] In the technical solution provided in this embodiment, the clamping fixture includes: multiple upper clamping fixtures 10, a magnetically attached lower clamping fixture 20, and multiple magnetically attached linkage rods 30; the multiple upper clamping fixtures 10 are opposite to the lower clamping fixtures 20, and are arranged sequentially and side-by-side in a first direction to form a cutting interval between adjacent upper clamping fixtures 10; the first clamping surface 10a of the upper clamping fixture 10 and the second clamping surface 20a of the lower clamping fixture 20 are opposite to each other, and the first clamping surface 10a has multiple sequentially arranged linkage rods 30 in a second direction. A first groove 10b is arranged side-by-side and coated with a polyurethane coating. A first clamping surface 10a has multiple second grooves 20b arranged side-by-side in a second direction, also coated with a polyurethane coating. The multiple first grooves 10b and multiple second grooves 20b are opposite each other. A clamping space for holding ceramic sleeves extending in the first direction is formed between the polyurethane coatings 13 and 22 of the opposing first and second grooves. The second direction is perpendicular to the first direction. Multiple ceramic sleeves 100 to be cut can be placed in the corresponding clamping space in the first direction, i.e., between the first grooves 10b and the second grooves 20b, and clamped between the two polyurethane coatings. The lower clamping fixture 20 is provided with multiple first through holes 21, and multiple magnetic linkage rods 30 are movably disposed in the multiple first through holes 21 and connected to the upper clamping fixture 10. The processing platform 40 includes a placement platform 41, a sleeve cutting machine 42, and a displacement driving mechanism 43. The placement platform 41 is an electromagnetic magnetic platform used to place and magnetically attract the clamping fixture. The sleeve cutting machine 42 is disposed on the displacement driving mechanism 43. During cutting, the clamping fixture holding multiple ceramic sleeves 100 to be cut is placed on the electromagnetic magnetic platform. When the electromagnetic magnetic platform is turned on, the lower clamping fixture 20 can be magnetically attracted to the electromagnetic magnetic platform. Under the magnetic attraction of the electromagnetic magnetic platform, the multiple magnetic linkage rods 30 pull down the upper clamping fixture 10, so that the ceramic sleeves 100 to be cut can be securely held between the first groove 10b and the second groove 20b. Subsequently, the sleeve cutting machine 42 can be driven by the displacement driving mechanism 43, so that the sleeve cutting machine 42 forms a cutting interval between two adjacent upper clamping fixtures 10 to cut the ceramic sleeve 100 to be cut.
[0068] In the technical solution of this embodiment, there is no need to use epoxy resin to bond the ceramic sleeve 100 to be cut. Instead, a magnetic mechanical adsorption method is used to completely replace it, saving material costs in the fastening process.
[0069] The clamping fixture and machining platform 40 can be placed inside the machining protective cover 101, and an LED light source 102 is provided inside the machining protective cover 101.
[0070] Multiple magnetic linkage rods 30 are movably disposed within multiple first through holes 21, allowing for adjustable spacing between the multiple upper clamping fixtures 10 and the lower clamping fixtures 20. After lifting the multiple upper clamping fixtures 10, the ceramic sleeve 100 to be cut can be easily inserted between the first groove 10b and the second groove 20b. The dimensions of the first groove 10b and the second groove 20b match the diameter of the ceramic sleeve 100 to be cut.
[0071] Figure 6 This is a partial cross-sectional view of the clamping fixture of a ceramic sleeve cutting system according to an embodiment of the present invention. Figure 7 yes Figure 6 Enlarged image of A in the middle, combined with Figure 6 and Figure 7 As shown, the bottom of the first through hole 21 is a flared opening, and the bottom end of the magnetic linkage rod 30 is an enlarged diameter end 31. The enlarged diameter end 31 is located inside the flared opening to restrict the magnetic linkage rod 30 from coming out from the top direction of the first through hole 21.
[0072] The magnetic linkage rod 30 can be made of metal, such as steel, and can move toward the electromagnetic platform under the attraction of the electromagnetic magnetic platform.
[0073] The clamping space of the clamping fixture is used to clamp the ceramic sleeve 100 to be cut. A polyurethane coating layer is provided on the surface of the first groove 10b and the second groove 20b. The polyurethane coating layer is in direct contact with the ceramic sleeve 100 to be cut, which can reduce the stress concentration problem on the ceramic sleeve.
[0074] In practice, the clamping fixture holding the ceramic sleeve 100 to be cut is placed on the placement platform 41. With the electromagnetic suction platform off (not energized, i.e., without magnetic force), the upper clamping fixture 10 and the lower clamping fixture 20 remain relatively relaxed, and a certain distance is maintained between the magnetic linkage rod 30 and the electromagnetic suction platform. With the electromagnetic suction platform on (energized, i.e., generating magnetic force), the magnetic linkage rod 30 moves towards the electromagnetic suction platform under magnetic force, for example, directly contacting the platform to achieve magnetic attraction. The upper clamping fixture 10 and the lower clamping fixture 20 then move closer together, clamping the ceramic sleeve 100 to be cut between the first groove 10b and the second groove 20b.
[0075] During cutting, the displacement drive mechanism 43 drives the sleeve cutting machine 42, causing the cutting blade 421 of the sleeve cutting machine 42 to travel between two adjacent upper clamping fixtures 10. During travel, its bottom extends to the cutting groove of the second groove 20b, enabling the cutting of the ceramic sleeve 100 to be cut between the first groove 10b and the second groove 20b. The thickness of the cutting blade 421 can range from 0.5mm to 1mm.
[0076] Understandably, the number of upper clamping fixtures 10 arranged side-by-side determines the actual number of cutting blades for the ceramic sleeve to be cut, that is, the maximum number of cuts for one ceramic sleeve. In practice, the number of upper clamping fixtures 10 arranged can be set according to the actual need for the number of cuts. For example, the blank before cutting the ceramic sleeve can be designed as 1 out of 5 according to the process requirements, that is, one ceramic sleeve 100 to be cut is cut into 5 final products according to the cutting requirements.
[0077] The first direction can be the width direction of the clamping fixture, and the second direction can be the length direction of the clamping fixture.
[0078] In the handling clamping fixture, the clamped sleeve to be cut is prone to shaking and displacement, thus affecting the cutting position. In some embodiments of the present invention, the upper clamping fixture 10 includes: a magnetic contact cover plate 11 and an upper fixture part 12, wherein the upper fixture part 12, the magnetic contact cover plate 11, and the lower clamping fixture 20 are stacked sequentially; the magnetic contact cover plate 11 is provided with a plurality of second through holes 111, and a plurality of magnetic linkage rods 30 are movably disposed in the plurality of second through holes 111 and connected to the upper fixture part 12, and the first clamping surface 10a is disposed on the magnetic contact cover plate 11; the lower clamping fixture 20 is a magnetically controlled lower part, and the magnetic force of the magnetically controlled lower part is controllable to adjust the attraction force on the magnetic contact cover plate 11.
[0079] The magnetic contact cover plate 11 can be made of metal, such as steel. Under the attraction of the magnetic force of the lower magnetic control part, it can move towards the lower magnetic control part, so that the ceramic sleeve 100 to be cut is initially clamped between the first groove 10b and the second groove 20b. During the process of transporting the clamping fixture to the placement platform 41, the swaying of the ceramic sleeve 100 to be cut between the first groove 10b and the second groove 20b can be prevented.

Figure 9 This is a schematic diagram of the internal side view of the lower part of the magnetically controlled cutting system for a ceramic sleeve according to an embodiment of the present invention. Figure 10This is a schematic diagram of the internal structure of the lower part of the ceramic sleeve cutting system according to an embodiment of the present invention, showing the rotating control magnet 26 to a first rotation angle. Figure 11 This is a schematic diagram of the internal side view of the lower part of the magnetically controlled cutting system for a ceramic sleeve according to an embodiment of the present invention, showing the rotating control magnet 26 to a second rotation angle. Figures 8 to 11 As shown, in implementation, the lower magnetically controlled part can be controlled electromagnetically. However, this method requires an external power supply, which makes the entire part susceptible to the influence of the power line and inconvenient to transport. In the embodiments of this application, a non-electromagnetic control method can also be used. In this implementation, the lower magnetically controlled part includes: a lower tooling part 23, at least one first magnet 24, at least one second magnet 25, and a control magnet 26. At least one first magnet 24 is disposed on a first side within the lower tooling part 23, and at least one second magnet 25 is disposed on a second side within the lower tooling part 23. The control magnet 26 is rotatably located between the first magnet 24 and the second magnet 25. The N pole of the first magnet 24 faces the second clamping surface 20a of the lower clamping tooling 20, and the S pole of the first magnet 24 faces away from the lower clamping tooling. The second clamping surface 20a of the lower clamping fixture 20 is such that the S pole of the second magnet 25 faces the second clamping surface 20a of the lower clamping fixture 20, and the N pole of the second magnet 25 faces away from the second clamping surface 20a of the lower clamping fixture 20. When the control magnet 26 is rotated to a first rotation angle, the N pole of the control magnet 26 faces the S pole of the first magnet 24, and the S pole of the control magnet 26 faces the N pole of the second magnet 25. When the control magnet 26 is rotated to a second rotation angle, the S pole of the control magnet 26 faces the S pole of the first magnet 24, and the N pole of the control magnet 26 faces the N pole of the second magnet 25. That is, the control magnet 26 is rotatably disposed on the lower part 23 of the fixture. Before the ceramic sleeve 100 to be cut is placed on the clamping fixture, the lower part of the magnetic control fixture does not need magnetic attraction to contact the cover plate 11.
[0081] Rotate the control magnet 26 to a first rotation angle, so that the N pole of the control magnet 26 faces the S pole of the first magnet 24 and the S pole of the control magnet 26 faces the N pole of the second magnet 25. The magnetic forces of the first magnet 24, the second magnet 25 and the control magnet 26 can cancel each other out and are in a demagnetized state.
[0082] After the ceramic sleeve 100 to be cut is placed in the clamping fixture, the control magnet 26 can be rotated to a second rotation angle. The S pole of the control magnet 26 faces the S pole of the first magnet 24, and the N pole of the control magnet 26 faces the N pole of the second magnet 25. The magnetic forces of the first magnet 24, the second magnet 25, and the control magnet 26 are superimposed, and they are in a magnetized state, thereby achieving initial clamping between the first groove 10b and the second groove 20b. To maintain the rotation angle of the control magnet 26, an angle limiting mechanism can also be provided to limit the rotation angle of the control magnet 26. For example, it can be a plug rod, which can be detachably inserted into the lower part 23 of the fixture. The number of plug rods can be one or more, and multiple plug rods can be inserted into different rotation angle positions of the control magnet 26. During the rotation of the control magnet 26, the plug rod is removed. During the limiting, the plug rod is inserted. It is easy to understand that in practice, the angle limiting mechanism is not limited to the structural form of the plug rod.
[0083] It is easy to understand that this initial clamping is relative to the final clamping between the first groove 10b and the second groove 20b after the electromagnetic suction platform is opened. In the initial clamping, the magnetic attraction force is relatively small, while in the final clamping, the magnetic attraction force is relatively large.
[0084] Please combine Figure 4 As shown, in the second direction, multiple magnetic linkage rods 30 can be respectively disposed on both sides of the upper part 12 of the fixture. During final clamping, the magnetic linkage rods 30 disposed on both sides of the upper part 12 of the fixture pull down the upper part 12 of the fixture. That is, the tensile stress on both sides of the upper part 12 of the fixture is relatively concentrated. There are multiple clamping spaces for clamping the ceramic sleeve to be cut, and they are arranged sequentially from one side to the other side of the upper part 12 of the fixture. Therefore, the ceramic sleeve in the clamping space located in the middle area of the upper part 12 of the fixture is prone to loosening due to insufficient force. If a greater magnetic attraction force is applied to the magnetic linkage rods 30 on both sides of the upper part 12 of the fixture, the ceramic sleeve is prone to being damaged by clamping. In order to overcome the above problems, in the embodiments of the present invention, in the second direction, the thickness of the upper part 12 of the fixture gradually decreases from the middle to the sides. In this solution, different gravity is used, namely, the middle is heavier and the two ends are lighter, and magnetic attraction on both sides is used. The combination of the two can apply a relatively uniform clamping force to the ceramic sleeves to be cut that are arranged from one side to the other on the upper part 12 of the tooling.
[0085] Figure 12 This is a partially enlarged view of the positions of the first pressing surface 11a of the magnetically contacting cover plate 11 and the second pressing surface 12a of the upper part of the tooling 12 in a ceramic sleeve cutting system according to an embodiment of the present invention. Figure 13This is a partially enlarged view of the first pressing surface 11a of the magnetically contacting cover plate 11 of the ceramic sleeve cutting system according to an embodiment of the present invention, after the second pressing surface 12a of the upper part of the tooling 12 is brought close together. Figure 14 This is a partially enlarged view of the first pressing surface 11a of the magnetically contacting cover plate 11 of the ceramic sleeve cutting system according to an embodiment of the present invention, after it comes into close contact and rubs against the second pressing surface 12a of the upper part of the tooling 12. Please refer to the view of the protrusion 12 to... Figure 14 As shown, in addition, at the instant the electromagnetic magnetic platform is energized, it will generate a large magnetic attraction force. Under the combined pulling force of multiple magnetic linkage rods 30, the upper part 12 of the fixture is easily impacted and cracked by the rapid impact force of the upper part 12 of the fixture. In this embodiment, multiple magnetic linkage rods 30 are movably connected to the upper part 12 of the fixture in the second direction. The first pressing surface 11a of the magnetic contact cover plate 11 is opposite to the second pressing surface 12a of the upper part 12 of the fixture. The first pressing surface 11a is provided with multiple convex surfaces 112 arranged side by side in the second direction, and the second pressing surface 12a is provided with multiple concave surfaces 121 arranged side by side in the second direction. The multiple convex surfaces 112 are one-to-one opposite to the multiple concave surfaces 121. After the electromagnetic suction platform is powered on, the first clamping surface 11a and the second clamping surface 12a use a convex surface 112 and a concave surface 121 for clamping. Compared to the clamping method of two planes, the downward magnetic attraction force in the clamping of the convex surface 112 and the concave surface 121 is decomposed into a downward component force and a horizontal component force, thereby reducing the instantaneous impact force applied by the upper part of the fixture 12. That is, after fastening, the magnetic contact cover plate and the upper part of the fixture will generate lateral displacement, and the generated lateral displacement can be used to reduce the impact of instantaneous pressure on the ceramic sleeve.
[0086] In specific implementation, the multiple convex surfaces 112 and the multiple concave surfaces 121 have a misalignment distance in the second direction, which can be between 2mm and 5mm, such as 3.5mm. That is, there is a movable distance between the magnetic contact cover plate 11 and the upper part of the tooling 12 in the second direction. Under the action of the aforementioned downward and horizontal components of force, the magnetic contact cover plate 11 and the upper part of the tooling 12 will simultaneously generate movement distances in both vertical and horizontal directions.
[0087] In the implementation scheme that enables simultaneous vertical and horizontal movement between the magnetic contact cover plate 11 and the upper part of the fixture 12, multiple magnetic linkage rods 30 and the upper part of the fixture 12 can be connected by hinges. Alternatively, specifically, the upper part of the fixture 12 has an embedded hole, and the end of the magnetic linkage rod 30 extends into the embedded hole. The opening size of the embedded hole is smaller than the inner diameter of the embedded hole, and the size of the end of the magnetic linkage rod 30 is larger than the opening size of the embedded hole, but smaller than the inner diameter of the embedded hole. This allows the end of the magnetic linkage rod 30 to simultaneously move in both vertical and horizontal directions within the embedded hole.
[0088] Figure 15 This is a top view schematic diagram of the clamping fixture of the ceramic sleeve cutting system according to another embodiment of the present invention. Figure 16 yes Figure 15 Please see the enlarged image of B in the image. Figure 15 and Figure 16 As shown, in related technologies, the clamping fixture needs to be fixed to the processing platform 40 with bolts. Over time, after many fixings, the holes of the fixing bolts are easily worn, resulting in inaccurate positioning of the clamping fixture on the processing platform 40, which reduces the cutting accuracy of the ceramic sleeve. In this solution, a magnetic positioning method can be used, which has higher durability. In implementation, in the second direction, multiple magnetic linkage rods 30 are arranged sequentially at intervals on both sides of the lower clamping fixture 20. The electromagnetic magnetic platform includes: a placement groove, which includes multiple electromagnetic positioning points and an electromagnetic attraction surface. The placement groove is used to place the clamping fixture. The positions of the multiple electromagnetic positioning points correspond to the arrangement positions of the multiple magnetic linkage rods 30. When the clamping fixture is placed in the placement groove, the multiple electromagnetic positioning points and the multiple magnetic linkage rods 30 are aligned one-to-one, and the electromagnetic attraction surface covers the bottom of the placement groove. In use, firstly, the clamping fixture containing the ceramic sleeve to be cut is placed in the placement groove of the processing platform 40, ensuring that the clamping fixture and the placement groove are roughly aligned. Then, by energizing multiple electromagnetic positioning points, a magnetic force is generated. Under the action of the magnetic force, the multiple electromagnetic positioning points and multiple magnetic linkage rods 30 are aligned and attracted one-to-one. If the relative positions deviate, the magnetic force will cause the deviated electromagnetic positioning points and magnetic linkage rods 30 to move closer together and align. Then, by opening the electromagnetic attraction surface, the lower clamping fixture 20 is magnetically attracted as a whole. Specifically, for example, there are 12 electromagnetic positioning points and 12 magnetic linkage rods 30, with 6 arranged alternately on both sides of the lower clamping fixture 20.
[0089] Furthermore, in this solution, multiple electromagnetic positioning points and multiple magnetic linkage rods 30 are spaced apart in the first direction. During electromagnetic alignment, the electromagnetic positioning points in the first direction are activated sequentially, allowing them to gradually align and engage with the magnetic linkage rods 30 in the first direction. For example, Figure 17 This is a schematic diagram of the alignment structure of a ceramic sleeve cutting system according to another embodiment of the present invention, as shown below. Figure 17 As shown, the process of inserting the clamping device into the electromagnetic suction platform, and the alignment and engagement of multiple electromagnetic positioning points and multiple magnetic linkage rods 30, includes:
[0090] Alignment stage: The electromagnetic positioning points at the bottom of the electromagnetic magnetic platform will be attracted one by one from point 1 to point 6, so that the electromagnetic positioning points in the first direction can gradually align and engage with the magnetic linkage rod 30 in the first direction.
[0091] During the positioning process, the infrared sensors 79 on both sides of the fixture can monitor the positioning status of the fixture.
[0092] Detection Phase: Infrared sensors 79 can be positioned on both sides of the placement area of the clamping fixture on the electromagnetic suction platform. If the clamping fixture is aligned in the placement area, the infrared light from both sides of the infrared sensors 79 is not blocked by the clamping fixture. If there is a misalignment between the clamping fixture and the placement area, the infrared light from at least one side of the infrared sensor 79 will be blocked by the clamping fixture, thus indicating that the clamping fixture has deviated. The alignment phase described above is repeated until the detection phase is passed, i.e., the infrared light from both sides of the infrared sensors 79 is not blocked by the clamping fixture, and the infrared light from the emitting end of the infrared sensor 79 passes smoothly to the receiving end of the infrared sensor 79.
[0093] Multiple clamping fixtures can be set up on the electromagnetic magnetic platform. When all clamping fixtures meet the preset level requirements of the infrared sensor 79, and all clamping fixtures are in place, the electromagnetic magnetic platform will attract all fixtures.
[0094] Figure 18 This is a top view schematic diagram of the clamping fixture of the ceramic sleeve cutting system according to an embodiment of the present invention being installed into the material handling fixture 50. Figure 19 This is a cross-sectional view of the clamping fixture of the ceramic sleeve cutting system according to an embodiment of the present invention, showing the fixture being inserted into the material handling fixture 50. Please refer to [link / reference]. Figure 18 and Figure 19As shown, during the process of placing multiple ceramic sleeves 100 to be cut one by one into multiple clamping spaces of the clamping fixture, it is also necessary to align the edges of the multiple ceramic sleeves 100 to be cut. In order to facilitate the alignment operation, in this embodiment of the solution, the ceramic sleeve cutting system further includes: a material placement fixture 50, which has a receiving space, an opening at the top of the material placement fixture 50, and an alignment groove 51 of a predetermined depth at the bottom support surface of the receiving space; when the extending direction of the clamping space of the clamping fixture is toward the bottom of the receiving space, the material is inserted into the receiving space through the top opening, and the alignment groove 51 is located in the extending direction of the receiving space and communicates with the receiving space. The clamping fixture is supported at the bottom of the receiving space. After the sleeve to be cut is placed in the receiving space, one end of it extends out of the edge of the clamping fixture and into the alignment groove 51. The depth of the alignment groove 51 is the dimension by which the sleeve to be cut extends outward from the clamping fixture for alignment. For example, the depth of the alignment groove 51 can be 1mm-2mm, and the other end of the sleeve to be cut can be reserved by 2mm-3mm. After alignment, the magnetic force of the lower part of the magnetic control can be controlled to apply an attractive force to the magnetic contact cover plate 11, completing the initial fastening of the ceramic sleeve to be cut. Then, the clamping fixture can be removed from the placement fixture 50 and placed on the electromagnetic magnetic platform for cutting. After cutting, the electromagnetic magnetic platform is turned off, and the cut ceramic sleeve can be removed. Compared with the prior art, the cutting process of the ceramic sleeve 100 does not require the use of epoxy resin glue, glue remover, and processing cleaning agent, which is safer and does not require expensive laser processing equipment, thus reducing costs. Meanwhile, the processing platform 40 has been changed from the original mechanical fixed clamping fixture to an electromagnetic fixed clamping fixture, thus comprehensively improving the efficiency of material placement and loading.
[0095] Furthermore, in the aforementioned ceramic sleeve cutting system, the processing platform 40 further includes: a coolant sedimentation section 61, a coolant filter screen 62, a coolant filter cotton 63, and a water tank 64. The coolant sedimentation section 61, the coolant filter screen 62, the coolant filter cotton 63, and the water tank 64 are sequentially connected to form a loop, constituting a coolant sedimentation and filtration device. During the cutting of ceramic sleeves by the sleeve cutting machine 42, the coolant in the water tank 64 can be drawn by a pump and used to rinse and cool the cutting blade 421 of the sleeve cutting machine 42 via the cold liquid inlet pipe 65. Specifically, the coolant in the cold liquid inlet pipe 65 enters the coolant chamber 66 and is sprayed onto the cutting blade 421 by the cooling nozzle 67. After rinsing, the coolant, after sedimentation and filtration by the coolant sedimentation section 61, the coolant filter screen 62, and the coolant filter cotton 63, enters the water tank 64 to form a loop. By filtering impurities in the coolant, the cutting accuracy of the ceramic sleeves by the sleeve cutting machine 42 can be improved. In other words, after the coolant is filtered, the impact of impurities in the coolant on the cutting accuracy of the ceramic sleeves can be reduced.
[0096] In the above embodiments, multiple electromagnetic positioning points can be used to achieve precise positioning of the clamping fixture. By performing three-stage impurity filtration on the coolant, the cutting accuracy of the sleeve cutting machine 42 on the ceramic sleeve can be improved. To further improve the cutting accuracy, the displacement driving mechanism 43 includes: a transverse driving mechanism 431 that drives the sleeve cutting machine 42 to move laterally on the placement platform 41, and a longitudinal driving mechanism 432 that drives the sleeve cutting machine 42 to move longitudinally on the placement platform 41. Specifically, the transverse driving mechanism 431 can be a precision motor 104 mounted on the X-axis track, and the longitudinal driving mechanism 432 can be a precision motor 106 mounted on the Y-axis track. The transverse driving mechanism 431 and the longitudinal driving mechanism 432 use linear guides, with a motion accuracy of ≤1µm. The X-axis and Y-axis are perpendicular. The speed of the X-axis power precision motor is adjustable, and the speed of the Y-axis power precision motor is adjustable. On the guide rail of the precision lead screw, the precision motor, in conjunction with the sensor, executes PLC actions. The precision motor has a stepping accuracy of 1µm. The processing platform 40 also includes a grating ruler and a control unit. The displacement drive mechanism 43 and the grating ruler are both electrically connected to the control unit. The grating ruler is used to sense the motion trajectory of the sleeve cutting machine 42. The control unit is used to: control the displacement drive mechanism 43 to drive the sleeve cutting machine 42 to advance at a first cutting speed to cut the ceramic sleeve of the clamping fixture according to the cutting command; acquire the motion trajectory sensed by the grating ruler and calculate the actual tolerance of the motion trajectory; if the actual tolerance is greater than a preset tolerance, drive the sleeve cutting machine 42 to advance at a second cutting speed to cut the ceramic sleeve of the clamping fixture, where the second cutting speed is less than the first cutting speed. Of course, in practice, it is not limited to a single speed reduction. For example, after driving the sleeve cutting machine 42 to advance at the second cutting speed, if the actual tolerance is greater than the preset tolerance, drive the sleeve cutting machine 42 to advance at a third cutting speed to cut the ceramic sleeve of the clamping fixture, where the third cutting speed is less than the second cutting speed.
[0097] The model of the grating ruler can be Lb382c ML4240, and the resolution of the grating ruler can be 0.1 micrometers.
[0098] The control unit can employ PLC programming technology and a touch screen (107 screen) to program and pre-store the motion trajectory of the displacement drive mechanism 43. Different cutting paths can be set for different ceramic sleeves. This comprehensively improves the stability and output efficiency of the cutting process. Through the pre-stored program, automatic cutting of the ceramic sleeve is achieved. The dimensions and end face standards of the ceramic sleeve can meet design requirements, such as dimensional tolerance ≤ ±0.001mm and end face roughness ≤ Ra0.5. Before starting the ceramic sleeve cutting system, the sleeve cutting machine 42 is set to automatically return to the origin. After the ceramic sleeve cutting system starts, the user can select the pre-stored program corresponding to the desired cutting path and perform cutting according to the selected pre-stored program.
[0099] For ease of understanding, the following embodiment is used as an example. The cutting accuracy of the ceramic sleeve cutting system is ±0.001mm (i.e., preset tolerance = ±0.001mm). In this solution, high-precision cutting capability can be achieved by further reducing the cutting speed at the second cutting speed, while simultaneously monitoring and providing feedback on the grating ruler dimensions. For example, the first cutting speed of the sleeve cutting machine 42 is 0.15m / min. When the grating ruler cutting tolerance is >0.001mm or when there is fluctuation, the cutting speed will begin to decrease to the second cutting speed, for example, 0.10mm / min. If the grating ruler cutting tolerance is still >0.001mm, the cutting speed can then be further reduced to the third cutting speed, which is 0.05mm / min.
[0100] In specific implementation, cutting one row of ceramic sleeves is considered as one unit. After cutting one unit, the cutting of the second unit of ceramic sleeves begins. The sleeve cutting machine 42 is still driven to advance at the first cutting speed to cut the ceramic sleeves of the clamping fixture, for example, using a normal cutting speed of 0.15mm / min.
[0101] In practical implementation, the above-mentioned ceramic sleeve cutting system further includes a position sensor on the processing platform 40. The position sensor is used to sense whether the sleeve cutting machine 42 is at the origin, cutting start point, or non-cutting area position of the placement platform 41. Specifically, the position sensor includes a homeostasis sensor, a processing start point zeroing sensor, and an anti-overshoot sensor. The homeostasis sensor senses that the sleeve cutting machine 42 is at the origin of the placement platform 41; the processing start point zeroing sensor senses that the sleeve cutting machine 42 is at the cutting start point position of the placement platform 41; and the anti-overshoot sensor senses that the sleeve cutting machine 42 is in the non-cutting area position of the placement platform 41. By acquiring the sensing signals from the homeostasis sensor, the processing start point zeroing sensor, and the anti-overshoot sensor, the position of the sleeve cutting machine 42 can be monitored. The origin return sensors include an X-axis origin return sensor 71 and a Y-axis origin return sensor 72; the machining start point zeroing sensors include an X-axis machining start point zeroing sensor 73 and a Y-axis machining start point zeroing sensor 74; and the anti-overshoot sensors include an X-axis anti-overshoot sensor 75 and a Y-axis anti-overshoot sensor 76. Additionally, an X-axis sensor interference terminal 77 and a Y-axis sensor interference terminal 78 are provided. The X-axis sensor interference terminal 77 is used to sense the rays from the X-axis origin return sensor 71, the X-axis machining start point zeroing sensor 73, and the X-axis anti-overshoot sensor 75. The Y-axis sensor interference terminal 78 is used to sense the rays from the Y-axis origin return sensor 72, the Y-axis machining start point zeroing sensor 74, and the Y-axis anti-overshoot sensor 76.
[0102] The X-axis track 103 is equipped with an X-axis mechanical limit device 81, and the Y-axis track 105 is equipped with a Y-axis mechanical limit device 82.
[0103] The ceramic sleeve cutting system provided in this invention utilizes PLC programming, mechanical and laser position sensors, a grating ruler, a high-precision displacement drive mechanism 43, an electromagnetic suction platform, and a magnetically controlled lower part to achieve two-stage tightening: initial tightening and final tightening. Combined with a coolant sedimentation and filtration device, it improves product cutting accuracy while reducing end chipping and end-face scratches during ceramic sleeve cutting. Specifically, it can improve the cutting accuracy of ceramic sleeves from ±0.02mm to ±0.001mm. This cutting system can stably process various precision products and various standard and non-standard ceramic sleeves, reducing the end-face grinding process and improving the processing yield of various standard and non-standard ceramic sleeves. In other words, it reduces the end-face grinding process required due to end-face defects. This provides strong support for the processing of ceramic sleeve products, especially the market-oriented mass production and application of high-precision non-standard short ceramic tubes. It reduces processing steps, improves processing accuracy, significantly reduces processing costs, and also increases the production capacity of non-standard small-size sleeves.
