Description

Technical Field

[0001] This invention belongs to the field of ceramic processing technology, and in particular relates to an automatic chamfering machine for ceramic inserts. Background Technology

[0002] Ceramic ferrules are core precision positioning components in fiber optic communication networks and are widely used in fiber optic connector manufacturing and other fields. To ensure that the ceramic ferrule can be smoothly pressed into the metal tailstock and to prevent sharp edges from picking up metal chips that could clog the inner hole, the tail end usually needs to be chamfered.

[0003] Traditional chamfering devices, such as the ceramic ferrule chamfering device disclosed in application number CN2015207114554, rely on V-grooves, baffles, and pressure rollers for positioning the ceramic ferrule. Although the pressure roller shaft is designed with an included angle to generate a component force pointing towards the baffle, this is a dynamic friction limit. When the grinding wheel applies grinding force, if the friction component force is insufficient to resist the cutting axial component force, the ceramic ferrule may still move away from the baffle, such as a small radial runout or vibration, resulting in a decrease in chamfering accuracy or even edge chipping.

[0004] Furthermore, as disclosed in application number CN2018201404932, the ceramic ferrule chamfering processing equipment uses a clamping mechanism to position the ceramic ferrule in conjunction with the plate and feeding mechanism. Although this can reduce the possibility of the ceramic ferrule shifting, the axial clamping force of the ceramic ferrule relies on the clamping mechanism at the rear. The force is transmitted to the processing station layer by layer through the ceramic ferrules arranged in a series in the extrusion guide groove. This series thrust is affected by the friction of the guide groove and the surface condition of the ceramic ferrule. The hard and brittle ceramic ferrules are connected end to end and squeezed against each other, which can easily cause minor chipping or end face scratches, thus restricting the bottleneck of achieving high-precision processing. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic chamfering machine for ceramic ferrules, which helps to achieve high-precision processing.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an automatic chamfering machine for ceramic ferrules, comprising a worktable, wherein the worktable is provided with: The first drive motor has a coaxial drive connection between its output end and a limiting disk and a turntable. The outer circumferential surface of the turntable is provided with a plurality of receiving slots evenly distributed along the circumferential direction. The receiving slots penetrate the front and rear end faces of the turntable. The limiting disk abuts against the rear end of the receiving slot. When the ceramic insert is positioned in the receiving slot, the end to be chamfered extends forward into the receiving slot, and the other end abuts against the limiting disk. The second drive motor has a first pressure roller connected to its output end. A first elastic ring is fitted on the outer circumference of the first pressure roller. The first pressure roller and the turntable are located in the same vertical plane and are horizontally adjacent to each other. A chamfering processing station is formed between the first elastic ring and the turntable. A grinding mechanism is used to grind and chamfer the ceramic insert that is conveyed to the chamfering processing station; The feeding mechanism includes a feeding track, the end of which extends to the outer periphery of the turntable to form a feeding station. The feeding station is located in the upper region of the turntable and is used to sequentially guide the ceramic inserts to be processed into the receiving groove passing through the feeding station. The receiving frame, located directly below the turntable, is used to receive the chamfered ceramic inserts.

[0007] Preferably, the bottom of the receiving groove is provided with two support rollers spaced apart along the circumferential direction, and the axis of the support rollers is parallel to the axis of the turntable; when the ceramic insert is positioned in the receiving groove, the outer cylindrical surface of the ceramic insert rolls against the two support rollers.

[0008] Preferably, the grinding mechanism includes a third drive motor, the output end of which is connected to a grinding wheel extending to the chamfering station. The side of the grinding wheel away from the third drive motor is a grinding surface, which abuts against the end of the ceramic insert that extends out of the turntable and is to be chamfered. The grinding wheel and the first pressure roller are distributed on the same radial outer side of the turntable.

[0009] Preferably, the device also includes an axial positioning mechanism, which is arranged circumferentially between the loading station and the chamfering station on the turntable, and is used to apply an axial thrust toward the limiting plate as the ceramic insert moves with the turntable.

[0010] Preferably, the first drive motor is fixedly connected to the worktable via a first motor mounting bracket. The axial positioning mechanism includes a connecting seat fixedly mounted on the top of the first motor mounting bracket. The connecting seat is provided with an arc-shaped guard plate and an axial pushing member. The concave arc surface of the arc-shaped guard plate corresponds to the outer circumferential surface of the turntable and is used to radially limit and prevent the ceramic insert in the receiving groove from falling out. The axial pushing member is used to apply the rearward axial thrust to the ceramic insert.

[0011] Preferably, the axial pressing member is an elastic limiting pressure strip, the connecting end of the limiting pressure strip is fixedly connected to the connecting seat, and the free end of the limiting pressure strip extends to the moving trajectory of the ceramic insert, relying on the elastic deformation generated by the extrusion to push the ceramic insert against the limiting plate.

[0012] Preferably, the axial pressing member includes a drive shaft rotatably mounted on the connecting seat, the drive shaft extending in the left-right direction, a second pressure roller fixed on the drive shaft, and a second elastic ring sleeved on the outer circumferential surface of the second pressure roller; The drive shaft is connected to the output end of the first drive motor via a non-planar reversing transmission assembly; when the first drive motor drives the turntable to rotate, it simultaneously drives the second pressure roller to rotate via the non-planar reversing transmission assembly, so as to generate a rearward axial thrust on the ceramic ferrule using the second elastic ring.

[0013] Preferably, the non-planar reversing transmission assembly includes a rotating seat, a worm, and a worm wheel. The rotating seat is fixedly mounted on the connecting seat, the worm is rotatably engaged with the rotating seat, a driven wheel is fixedly mounted on the worm, a drive wheel is fixedly connected to the output end of the first drive motor, the drive wheel and the driven wheel are connected by a belt drive, and the worm wheel is fixedly mounted on the transmission shaft, engaging with the worm in a transmission manner.

[0014] Preferably, the first drive motor is a dual-axis motor, and the limiting plate and the turntable are connected in sequence on the first output shaft extending forward of the dual-axis motor, and the indexing plate is fixedly connected on the second output shaft extending backward of the dual-axis motor. The indexing plate rotates synchronously with the turntable on the same axis. The outer edge of the indexing plate is provided with a plurality of through slots. A tooth is formed between two adjacent through slots. The through slots correspond one-to-one with the receiving slots, or the tooth corresponds one-to-one with the receiving slots. The workbench is equipped with a position detection sensor that cooperates with the indexing plate. The detection end of the position detection sensor is set to the outer edge of the indexing plate to detect the alternating changes of the through groove and the teeth and output a station synchronization signal to reduce the speed of the first drive motor when the ceramic ferrule enters the processing station and increase the speed of the first drive motor when the ceramic ferrule leaves the processing station.

[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. By employing a design that combines a turntable with a through-hole receiving groove and a rear limiting plate, each ceramic ferrule is individually isolated and positioned within its own receiving groove. The rear end directly abuts against the fixed limiting plate, eliminating the layer-by-layer transmission of thrust between ceramic ferrules. This fundamentally avoids mutual collisions and compression between hard and brittle ceramic ferrules, which helps achieve high-precision processing and also helps ensure a high yield rate. 2. By adding an axial positioning mechanism between the loading station and the chamfering station, before the ceramic insert enters the grinding station, the mechanism actively applies an axial thrust toward the limiting plate to the ceramic insert, ensuring that the end of the ceramic insert always presses against the limiting plate reference at the rear end when it is impacted by the grinding force of the grinding wheel, effectively resisting the cutting axial component force and ensuring extremely high chamfer size consistency. 3. By embedding parallel support rollers at the bottom of the receiving groove, the sliding friction of the ceramic ferrule during rotation is converted into rolling friction. At the same time, in conjunction with the first elastic ring wrapped around the first pressure roller, a combination of inner rolling support and outer flexible friction drive is achieved. This can provide sufficient rotation driving force and effectively reduce rotation resistance, greatly reducing the damage or scratches on the outer cylindrical surface of the ceramic ferrule during high-speed rotation grinding. 4. By cleverly utilizing the dual-output shaft motor structure, the machining end and the position detection end are spatially isolated, which can avoid the contamination of the position detection sensor by ceramic dust generated in the chamfering machining area; by utilizing the high-precision synchronous mapping relationship between the indexing plate and the turntable to output reliable signals, the equipment can accurately realize dynamic frequency conversion control of "slowing down for fine grinding when entering the work station and speeding up for circulation when leaving the work station", which greatly improves the efficiency of fully automatic production while ensuring high precision.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Example 1: As Figures 1 to 8 As shown, an automatic chamfering machine for ceramic inserts includes a worktable 1, on which a first drive motor 2, a second drive motor 3, a grinding mechanism 4, a feeding mechanism 5, and a receiving frame 6 are mounted. Preferably, the first drive motor 2 and the second drive motor 3 are servo motors.

[0021] In this embodiment, the output end of the first drive motor 2 is coaxially connected to the limiting disk 7 and the turntable 8. The outer circumferential surface of the turntable 8 is provided with multiple receiving grooves 81 evenly distributed along the circumferential direction. The receiving grooves 81 penetrate the front and rear end faces of the turntable 8, and the limiting disk 7 abuts against the rear end of the receiving grooves 81. When the ceramic ferrule 9 is positioned within the receiving groove 81, one end to be chamfered extends forward into the receiving groove 81, and the other end abuts against the limiting disk 7. This structural design achieves rigid isolation and positioning of the ceramic ferrule 9, eliminating the problems of end-to-end compression damage and edge chipping caused by series thrust in the prior art.

[0022] In this embodiment, the output end of the second drive motor 3 is connected to a first pressure roller 10. A first elastic ring 101 is fitted on the outer circumferential surface of the first pressure roller 10. The first pressure roller 10 and the turntable 8 are located in the same vertical plane and are horizontally adjacent to each other. A chamfering processing station 11 is formed between the first elastic ring 101 and the turntable 8. The first elastic ring 101 is made of an elastic and wear-resistant material, such as a rubber ring. During operation, the turntable 8 drives the ceramic ferrule 9 to revolve to the processing station. The first elastic ring 101 comes into frictional contact with the outer wall of the ceramic ferrule 9. The first pressure roller 10 and the first elastic ring 101 rotate and drive the ceramic ferrule 9 to rotate stably within the receiving groove 81.

[0023] In this embodiment, the grinding mechanism 4 is used to grind and chamfer the ceramic insert 9 that is conveyed to the chamfering processing station 11.

[0024] In this embodiment, the feeding mechanism 5 includes a feeding track 51 and a vibratory feeder (not shown in the figure, which is a conventional technical means). The first end of the feeding track 51 is connected to the output end of the vibratory feeder, and the end of the feeding track 51 extends to the outer periphery of the turntable 8 to form a feeding station 52. The feeding station 52 is located in the upper area of ​​the turntable 8 and is used to sequentially guide the ceramic inserts 9 to be processed into the receiving groove 81 passing through the feeding station 52. Furthermore, the feeding mechanism 5 also includes a feeding motor 53. The output end of the feeding motor 53 is connected to a lever 54. The feeding motor 53 drives the lever 54 to rotate around the output end of the feeding motor 53, so that one end of the lever 54 extends into or out of the feeding track 51. During the process of one end of the lever 54 extending into the feeding track 51, the lever 54 pushes the ceramic inserts 9 in the feeding track 51 forward, so that the ceramic inserts 9 fall into the receiving groove 81 quickly and accurately.

[0025] In this embodiment, the receiving frame 6 is located directly below the turntable 8. When the chamfered ceramic insert 9 leaves the chamfering processing station 11 as the turntable 8 revolves, it will leave the receiving groove 81 under the action of gravity and fall into the receiving frame 6 to complete the unloading.

[0026] Example 2: Figure 4 , Figure 6 and Figure 9As shown, the rest of the parts are the same as in Embodiment 1, except that two support rollers 82 are embedded at intervals along the circumferential direction at the bottom of the receiving groove 81, and the axis of the support rollers 82 is parallel to the axis of the turntable 8; when the ceramic insert 9 is positioned in the receiving groove 81, the outer cylindrical surface of the ceramic insert 9 rolls against the two support rollers 82.

[0027] By setting the support roller 82, the sliding friction of the ceramic ferrule 9 during rotation is converted into rolling friction. At the same time, in conjunction with the first elastic ring 101 wrapped around the first pressure roller 10, the combination of inner rolling support and outer flexible friction drive is achieved. This can provide sufficient rotation driving force and effectively reduce rotation resistance, greatly reducing the possibility of damage or scratches to the outer cylindrical surface of the ceramic ferrule 9 during high-speed rotation grinding.

[0028] In this embodiment, the grinding mechanism 4 includes a third drive motor 41. The output end of the third drive motor 41 is connected to a grinding wheel 42 extending to the chamfering processing station 11. The side of the grinding wheel 42 away from the third drive motor 41 is a grinding surface 421. The grinding surface 421 abuts against the end of the ceramic insert 9 extending from the turntable 8 to be chamfered. The grinding wheel 42 and the first pressure roller 10 are distributed on the same radially outer side of the turntable 8. Preferably, the third drive motor 41 is a servo motor.

[0029] During the chamfering process, the grinding force exerted by the grinding wheel 42 on the end of the ceramic insert 9 is mainly decomposed into an axial component pointing backward (which is offset by the rigid support formed by the rear limiting plate 7) and a tangential component along the circumferential tangent of the ceramic insert 9. It can be seen that with this structural design, the grinding force of the grinding wheel 42 does not generate a component that forces the ceramic insert 9 to move radially outward along the turntable 8. The advantage of this force characteristic is that it avoids the grinding reaction force being transmitted radially outward to the first elastic ring 101, thereby minimizing the radial runout of the ceramic insert 9 during processing and greatly ensuring the concentricity and surface accuracy of the chamfering process. It should be noted that since the first elastic ring 101 is made of flexible material, if it is subjected to radially outward compressive force, it will inevitably undergo irregular elastic deformation, which may cause the ceramic insert 9 to experience slight radial movement or vibration within the receiving groove 81.

[0030] Example 3: Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 10 As shown, the rest of the parts are the same as in Embodiment 1, except that it also includes an axial positioning mechanism 12. The axial positioning mechanism 12 is arranged circumferentially between the loading station 52 and the chamfering processing station 11 along the turntable 8, and is used to apply an axial thrust toward the limiting plate 7 to the ceramic insert 9 as it moves with the turntable 8.

[0031] Specifically, the first drive motor 2 is fixedly connected to the worktable 1 via the first motor mounting bracket 15. The axial positioning mechanism 12 includes a connecting seat 121 fixedly mounted on the top of the first motor mounting bracket. The connecting seat 121 is provided with an arc-shaped guard plate 122 and an axial pushing member 123. The concave arc surface of the arc-shaped guard plate 122 corresponds to the outer peripheral surface of the turntable 8 and is used to radially limit and prevent the ceramic insert 9 in the receiving groove 81 from falling off. The side of the arc-shaped guard plate 122 facing the loading station 52 is provided with a guide surface 1221. The axial pushing member 123 is an elastic limiting pressure strip 1231. The connecting end of the limiting pressure strip 1231 is fixedly connected to the connecting seat 121, and the free end of the limiting pressure strip 1231 extends to the moving trajectory of the ceramic insert 9, such as in an L-shape. When the ceramic insert 9 passes by, the elastic deformation generated by the compression limiting strip 1231 pushes the ceramic insert 9 tightly against the limiting plate 7 behind it, ensuring the uniformity of the grinding reference.

[0032] Example 4: Figures 11 to 13 As shown, the rest is the same as in Embodiment 3, except that the axial pressing member 123 structure in Embodiment 3 has been replaced. Specifically, the axial pressing member 123 includes a drive shaft 1232 rotatably mounted on the connecting seat 121. The drive shaft 1232 extends in the left-right direction, and a second pressure roller 1233 is fixed on the drive shaft 1232. A second elastic ring 12331 is sleeved on the outer circumferential surface of the second pressure roller 1233. The second elastic ring 12331 is made of an elastic wear-resistant material, such as a rubber ring.

[0033] The drive shaft 1232 is connected to the output end of the first drive motor 2 via a non-planar reversing transmission assembly 1234. The non-planar reversing transmission assembly 1234 includes a rotating seat 12341, a worm 12342, and a worm wheel 12343. The rotating seat 12341 is fixedly mounted on the connecting seat 121. The worm 12342 is rotatably engaged with the rotating seat 12341. A driven wheel 12344 is fixedly mounted on the worm 12342. A drive wheel 12345 is fixedly connected to the output end of the first drive motor 2. The drive wheel 12345 and the driven wheel 12344 are connected via a belt 12346. The worm wheel 12343 is fixedly mounted on the drive shaft 1232 and is engaged with the worm 12342. When the first drive motor 2 drives the turntable 8 to rotate, it synchronously drives the second pressure roller 1233 to rotate via the drive wheel 12345, belt 12346, driven wheel 12344, worm gear 12342, worm wheel 12343, and transmission shaft 1232. The second elastic ring 12331 contacts the outer cylindrical surface of the ceramic ferrule 9, applying a stable and continuous backward axial thrust to the ceramic ferrule 9 using rotational friction. Compared with the elastic limiting pressure strip 1231 in Embodiment 3, the second elastic ring 12331 is made of a softer material. Combined with the dynamic rotational friction to apply the thrust, it can effectively avoid scratches or damage to the outer cylindrical surface of the high-precision, hard and brittle ceramic ferrule 9, effectively ensuring the processing quality. On the other hand, this rotational follow-up contact method greatly reduces the local concentrated wear of the pressing component itself, significantly extending the service life of the second elastic ring 12331 and the overall positioning mechanism, making the equipment more suitable for long-cycle, high-intensity automated continuous production needs.

[0034] Example 5: Figures 1 to 4 as well as Figure 14 As shown, the rest is the same as in Embodiment 1, except that the first drive motor 2 is a dual-axis motor. The first output shaft of the dual-axis motor extends forward and is connected in sequence to the limit plate 7 and the turntable 8. The second output shaft of the dual-axis motor extends backward and is fixedly connected to the indexing plate 13. The indexing plate 13 and the turntable 8 rotate synchronously on the same axis.

[0035] In this embodiment, the outer edge of the indexing plate 13 is provided with a plurality of through slots 131, and a tooth 132 is formed between two adjacent through slots 131. The through slots 131 correspond one-to-one with the receiving slots 81, or the tooth 132 corresponds one-to-one with the receiving slots 81. A position detection sensor 14 (such as a slotted photoelectric switch) is provided on the worktable 1 to cooperate with the indexing plate 13. The detection end of the position detection sensor 14 is set directly opposite the movement trajectory of the outer edge of the indexing plate 13, so as to output a station synchronization signal by sensing the alternating changes of the through slots 131 and the tooth 132, so as to reduce the speed of the first drive motor 2 when the ceramic ferrule 9 enters the processing station, and increase the speed of the first drive motor 2 when the ceramic ferrule 9 leaves the processing station.

[0036] Specifically, during operation, the dual-axis motor drives the front and rear ends to rotate synchronously. The position detection sensor 14 senses the alternating changes in the through slots 131 and teeth 132 on the rear dial 13 and outputs a synchronous pulse signal representing the position status of the front turntable 8. Based on this signal, the control system dynamically reduces the speed of the first drive motor 2 for fine grinding when the ceramic ferrule 9 enters the processing station, and increases the speed of the first drive motor 2 to accelerate the flow when the ceramic ferrule 9 leaves the processing station. This design physically isolates the detection end and the processing end in space, which not only takes into account processing accuracy and production efficiency, but also avoids the contamination of the position detection sensor 14 by ceramic dust generated in the chamfering processing area.

[0037] It should be noted that the control system involved in this embodiment can be constructed using commercially available PLCs, microprocessors, or industrial control computers, in conjunction with corresponding motor drivers (such as servo drivers, stepper drivers, or frequency converters). For those skilled in the art, using conventional control devices to receive the electrical pulse signals output by the position detection sensor 14 and dynamically adjust the speed of the drive motor according to a preset logic program (such as a PID algorithm) is a conventional technical means in the field of electromechanical automation control. The specific hardware circuit connections and software programming logic are not described in detail here, nor do they constitute the core innovation of this invention.

[0038] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.

The drive shaft (1232) is connected to the output end of the first drive motor (2) via the non-planar reversing drive assembly (1234); when the first drive motor (2) drives the turntable (8) to rotate, it simultaneously drives the second pressure roller (1233) to rotate via the non-planar reversing drive assembly (1234), so as to generate a rearward axial thrust on the ceramic ferrule (9) using the second elastic ring (12331).

8. An automatic chamfering machine for ceramic inserts according to claim 7, characterized in that: The non-planar reversing transmission assembly (1234) includes a rotating seat (12341), a worm (12342), and a worm wheel (12343). The rotating seat (12341) is fixedly mounted on the connecting seat (121). The worm (12342) is rotatably engaged with the rotating seat (12341). A driven wheel (12344) is fixedly mounted on the worm (12342). A drive wheel (12345) is fixedly connected to the output end of the first drive motor (2). The drive wheel (12345) and the driven wheel (12344) are connected by a belt (12346). The worm wheel (12343) is fixedly mounted on the transmission shaft (1232) and is engaged with the worm (12342).

9. An automatic chamfering machine for ceramic inserts according to claim 1, characterized in that: The first drive motor (2) is a dual-axis motor. The first output shaft of the dual-axis motor extending forward is connected in sequence to the limiting disk (7) and the turntable (8). The second output shaft of the dual-axis motor extending backward is fixedly connected to the indexing disk (13). The indexing plate (13) rotates synchronously with the turntable (8) on the same axis. The outer edge of the indexing plate (13) is provided with a plurality of through slots (131). A tooth (132) is formed between two adjacent through slots (131). The through slots (131) correspond one-to-one with the receiving slots (81), or the tooth (132) corresponds one-to-one with the receiving slots (81). The worktable (1) is provided with a position detection sensor (14) that cooperates with the indexing plate (13). The detection end of the position detection sensor (14) is set to face the outer edge of the indexing plate (13) to output a station synchronization signal by sensing the alternating changes of the through slot (131) and the tooth (132). This reduces the speed of the first drive motor (2) when the ceramic ferrule (9) enters the processing station and increases the speed of the first drive motor (2) when the ceramic ferrule (9) leaves the processing station.
