Description

Technical Field

[0001] The invention relates to the technical field of ceramic yarn guide manufacturing, in particular to a ceramic yarn guide wire drawing and polishing device for textile machinery. Background Art

[0002] Yarn guides are widely used in the textile industry to guide yarns into the correct position of textile equipment to ensure the continuous flow of yarns throughout the entire textile process. There are many types of yarn guides according to material classification, especially ceramics. The main manufacturing material of ceramic yarn guides is ceramic powder (including aluminum oxide, silicon oxide, etc.), which is dry-pressed into blanks using a molding mold, and then sintered at high temperature in a high-temperature furnace, and then machined and polished to produce finished products.

[0003] As far as the current general manufacturing process in the industry is concerned, the sintered ceramic yarn guide undergoes machining to finely trim the yarn guide groove on it, and then, multiple ceramic yarn guides are subjected to fluid grinding and polishing one by one, and the friction or / grinding effect of the fine abrasive particles carried by the liquid medium is used to modify the surface of the yarn guide groove to achieve a smooth surface or mirror gloss. However, in actual operation, there are the following shortcomings, specifically: 1) In view of the high hardness characteristics of the ceramic yarn guide, the working efficiency of fluid grinding and polishing is extremely low, and the polishing of a single ceramic yarn guide takes a long time; 2) A large amount of abrasive is consumed during the polishing process, and for the purpose of environmental protection, special equipment is required to process and recycle the polishing liquid medium, and the production cost is relatively high; 3) Fluid grinding and polishing requires special equipment and facilities, and the initial investment is relatively high; 4) When facing non-straight or irregular contour shapes, it is difficult for fine abrasive particles to achieve full-range homogeneous friction / grinding, and the actual polishing effect is extremely poor, and the surface roughness difference of each area of ​​the yarn guide groove after polishing is large. Therefore, technical personnel are urgently needed to solve the above problems. Summary of the invention

[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify after many years of R&D experience in this industry, which ultimately led to the emergence of the textile machinery ceramic yarn guide wire drawing and polishing equipment.

[0005] The present invention relates to a wire drawing and polishing device for ceramic yarn guides of textile machinery, comprising a machine platform, a slide, a slewing bearing, a clamping fixture, a circumferential deflection drive mechanism and a wire drawing and polishing mechanism. The slide and the slewing bearing are both installed on the machine platform and are spaced at a set distance. The clamping fixture is used to clamp the ceramic yarn guide, which is directly supported by the slewing bearing and performs reciprocating deflection motion due to the rotational torque from the circumferential deflection drive mechanism. The wire drawing and polishing mechanism is directly supported by the slide. As the real-time deflection angle of the clamping fixture changes, the direction of the wire drawing and polishing force from the wire drawing and polishing mechanism on the ceramic yarn guide also changes.

[0006] As a further improvement of the technical solution disclosed in the present invention, the slewing bearing includes a bearing seat, a bearing assembly and a rotating shaft. The bearing seat is placed on the machine table and fixed as a whole in a detachable manner. The bearing assembly is composed of at least two bearings that are spaced apart and mounted in the bearing seat. The rotating shaft is used as a mounting and fixing base for the clamping tool, and it is subject to the common restraining force from each bearing.

[0007] As a further improvement of the technical solution disclosed in the present invention, the circumferential yaw drive mechanism includes a transition connection seat, a first rotary motor and a yaw transmission mechanism. The first rotary motor assists the transition connection seat to achieve fixed installation with the bearing seat. The rotational torque released by the first rotary motor in the running state is transmitted to the rotating shaft via the yaw transmission mechanism, so that the clamping fixture and the ceramic yarn guide can synchronously perform reciprocating yaw motion.

[0008] As a further improvement of the technical solution disclosed in the present invention, the yaw transmission mechanism includes a rotating disk, a bolt curve roller bearing, a yaw piece, a mounting column, a fan gear and a cylindrical gear. The cylindrical gear is integrated with the rotating shaft and is located directly below the clamping fixture. A strip sliding guide notch adapted to the bolt curve roller bearing is formed on the yaw piece. The mounting column serves as the mounting base of the yaw piece, and is inserted on the top wall of the transition connection seat in an upright state. The fan gear meshed with the cylindrical gear is fixed to the yaw piece in a detachable manner. The rotating disk is fixed to the main shaft of the first rotating motor in a detachable manner, and performs circumferential rotation under the action of the rotational torque from the first rotating motor. The bolt curve roller bearing uses the rotating disk as the mounting base and performs circumferential rotation following the rotating disk. At the same time, the bolt curve roller bearing performs reciprocating sliding motion along the strip sliding guide notch, the yaw piece and the fan gear perform reciprocating yaw motion synchronously, and the ceramic yarn guide also performs follow-up yaw motion.

[0009] As a further improvement of the technical solution disclosed in the present invention, an insertion hole for inserting the bolt curved roller bearing is formed on the rotating disk.

[0010] As a further improvement of the technical solution disclosed in the present invention, the number of the insertion holes is n, and the radial distance values ​​formed relative to the central axis of the rotating disk are r1, r2, ..., r n , then r1, r2, ..., r n Not equal values.

[0011] As a further improvement of the technical solution disclosed in the present invention, the wire drawing and polishing mechanism includes a motor mounting seat, a second rotating motor, a wire driving disc and a polishing wire. The second rotating motor is fixedly connected to the slide table by means of the motor mounting seat. The wire driving disc and the main shaft of the second rotating motor are fixed as a whole in a detachable manner. The polishing wire is in a closed ring shape, and it is wound around the wire driving disc and the ceramic yarn guide at the same time. Due to the rotational torque from the second rotating motor, the wire driving disc performs circumferential rotation motion, and the entire length of the polishing wire passes through the ceramic yarn guide. At the same time, the ceramic yarn guide follows the clamping tooling to perform a yaw motion. In this process, the polishing wire is able to apply a wire drawing and polishing force to the ceramic yarn guide.

[0012] As a further improvement of the technical solution disclosed in the present invention, the slide table includes a base plate, a sliding plate and a slide rail and slider assembly. The base plate is placed on the machine table and fixed as a whole in a detachable manner. The slide rail and slider assembly is assembled between the base plate and the sliding plate, and the sliding plate is able to perform sliding motion in a directional manner due to the pulling force. The sliding plate directly serves as the installation base of the wire drawing and polishing mechanism.

[0013] As a further improvement of the technical solution disclosed in the present invention, the slide table further includes a self-tensioning unit. Under the action of the self-tensioning unit, the sliding plate is continuously subjected to a pulling force, and the wire drawing and polishing force applied by the wire drawing and polishing mechanism to the ceramic yarn guide at different polishing stages tends to a constant value.

[0014] As a further improvement of the technical solution disclosed in the present invention, the self-tensioning unit includes a weight, a fixed pulley and a pulling rope. The fixed pulley is fixed to the tail of the bottom plate and completely extends beyond the machine. The two ends of the pulling rope are respectively connected to the weight and the sliding plate, and the force direction thereof is changed by winding around the fixed pulley. The weight is in a free hanging state, and uses its own weight to apply a constant pulling force to the sliding plate through the pulling rope.

[0015] The forming process of ceramic yarn guide blanks includes the following stages:

[0016] 1) using a forming mold to dry-press the ceramic powder into a blank, and placing the blank in a high-temperature furnace for high-temperature sintering to form a ceramic yarn guide blank;

[0017] 2) forming a yarn guide groove on the ceramic yarn guide blank by machining;

[0018] 3) Transfer the ceramic yarn guide blanks to the polishing workshop, clamp them one by one on the clamping tooling, and confirm the alignment of the polishing wire relative to the yarn guide groove;

[0019] 4) The wire drawing and polishing equipment is started. At the same time, the ceramic yarn guide follows the clamping fixture to perform reciprocating oscillation motion, and the polishing wire passes through the yarn guide groove according to the predetermined trajectory until the surface roughness of the yarn guide groove meets the design requirements.

[0020] In practical applications, the ceramic yarn guide wire drawing and polishing device for textile machinery disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:

[0021] 1) The wire drawing polishing process commonly used for metal materials is innovatively applied to ceramic materials. Compared with the traditional friction / grinding polishing process, the wire drawing polishing area is focused on the yarn guide groove, and the adjacent areas will not be affected. In this way, on the one hand, the yarn guide groove of the finished ceramic yarn guide has excellent surface roughness, which is conducive to reducing the friction resistance caused to the yarn in the subsequent actual weaving process; on the other hand, thanks to the directional and regional concentration of polishing, the polishing efficiency is greatly improved, and the total polishing time of a single ceramic yarn guide is controlled within 3 minutes;

[0022] 2) Because the polishing wire is sleeved on the ceramic yarn guide and is always kept in a tensioned state during the polishing process, the polishing wire is adjusted in direction and bending radius according to the specific contour of the yarn guide groove, so that it can achieve close contact with the pre-polishing area. Even in the case of non-straight or irregular contour shapes, the yarn guide groove can still be fully and high-quality polished;

[0023] 3) The self-developed ceramic yarn guide wire drawing and polishing equipment has a relatively low manufacturing cost, occupies a small area, has excellent durability and a very long service life; furthermore, only a small amount of polishing dust is generated during the wire drawing and polishing process, which can be recovered by installing a dust vacuum pipe at the wire drawing and polishing station.

DETAILED DESCRIPTION

[0038] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "left", "right", "front", "back", "up", "down", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0039] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2 The three-dimensional schematic diagrams of the ceramic yarn guide wire drawing and polishing equipment for textile machinery disclosed in the present invention are shown in two different perspectives. It can be seen that it is mainly composed of several parts such as a machine table 1, a slide 2, a slewing bearing 3, a clamping fixture 4, a circumferential yaw drive mechanism 5 and a wire drawing and polishing mechanism 6. Among them, the machine table 1 is fixed to the workshop floor with the help of anchor bolts. The slide 2 and the slewing bearing 3 are both installed on the machine table 1, and are arranged at a set distance along the left and right directions. The clamping fixture 4 is used to clamp the ceramic yarn guide, which is directly supported by the slewing bearing 3, and performs reciprocating yaw motion due to the rotational torque from the circumferential yaw drive mechanism 5. As shown Figure 3As shown in the figure, the slide 2 is mainly composed of several parts such as a base plate 21, a sliding plate 22 and a slide rail slider assembly 23. The base plate 21 is placed on the machine 1 and is fixed as a whole in a detachable manner. The slide rail slider assembly 23 is assembled between the base plate 21 and the sliding plate 22, and the sliding plate 22 is able to perform sliding motion in a directional manner due to the pulling force. The wire drawing and polishing mechanism 6 is directly supported by the sliding plate 22, and it includes a motor mounting seat 61, a second rotating motor 62, a wire driving disk 63 and a polishing wire 64. The second rotating motor 62 is fixedly connected to the slide 2 by means of the motor mounting seat 61. The wire driving disk 63 is directly driven by the second rotating motor 62. The polishing wire 64 is in a closed ring shape, and it is simultaneously wound around the wire driving disk 63 and the ceramic yarn guide (such as Fig.11 , 12 ).

[0040] During the wire drawing and polishing process of the yarn guide groove on the ceramic yarn guide, due to the rotational torque from the second rotating motor 62, the wire driving disk 63 performs circumferential rotation motion, and the polishing wire 64 passes through the ceramic yarn guide along its entire length. At the same time, the ceramic yarn guide follows the clamping tooling 4 to perform eccentric motion. During this process, the polishing wire 64 is able to apply a wire drawing and polishing force toward the yarn guide groove until the surface roughness of the yarn guide groove meets the design requirements.

[0041] By adopting the above-mentioned technical scheme, on the one hand, the wire drawing polishing process commonly used for metal materials is innovatively applied to ceramic yarn guides. Compared with the traditional friction / grinding polishing process, the wire drawing polishing area is focused on the yarn guide groove, and the adjacent areas will not be affected. In this way, on the one hand, the yarn guide groove of the finished ceramic yarn guide has excellent surface roughness, which is beneficial to reduce the friction resistance caused to the yarn in the subsequent actual weaving process; on the other hand, thanks to the directionality and regional concentration of the polishing, the polishing efficiency is greatly improved, and the total polishing time of a single ceramic yarn guide is controlled within 3 minutes; on the other hand, because the polishing wire 64 is sleeved on the ceramic yarn guide and is always kept in a tensioned state during the polishing process, the polishing wire 64 can be adjusted in direction and bending radius according to the specific contour of the yarn guide groove, so as to achieve close contact with the pre-polishing area, even in the face of non-straight or irregular contour shapes, the yarn guide groove can still be polished comprehensively and with high quality.

[0042] Here, it is also necessary to explain that the ceramic yarn guide wire drawing and polishing equipment disclosed in the present invention has a relatively low manufacturing cost, occupies a small area, and has excellent durability and an extremely long service life; furthermore, during the wire drawing and polishing process, only a trace amount of polishing dust is generated, which can be achieved by installing a dust vacuum recovery pipe at the wire drawing and polishing station, without the need for special environmental protection treatment equipment.

[0043] Depend on Figure 4 ,5 As shown in , 6, it can be clearly seen that the slewing bearing 3 is mainly composed of several parts such as a bearing seat 31, a bearing assembly 32 and a rotating shaft 33. Among them, the bearing seat 31 is placed on the machine table 1 and is fixed as a whole in a detachable manner. The bearing assembly 32 is composed of two bearings 321 that are mounted in the bearing seat 31, and the two are spaced at a set distance. The rotating shaft 33 is used as a mounting and fixing basis for the clamping tool 4, and it is subject to the joint restraining force from the two bearings 321. In this way, in the process of the clamping tool 4 performing circumferential rotational motion, the resistance it encounters is extremely small, and it maintains good rotational flexibility for a long time, which is conducive to achieving the running path of the polishing wire 64 when passing through the yarn guide groove in accordance with the design requirements.

[0044] As is known, according to design common sense, the circumferential yaw drive mechanism 5 can adopt a variety of design structures to achieve the drive of the rotating shaft 33, so that the clamping tool 4 can perform the yaw movement. However, here we recommend an implementation scheme with a simple design structure and easy manufacturing and implementation, specifically: Figure 7 , 8 As shown in the figure, the circumferential yaw drive mechanism 5 is mainly composed of a transition connection seat 51, a first rotary motor 52, and a yaw transmission mechanism 53. The first rotary motor 52 assists the transition connection seat 51 to achieve fixed installation with the bearing seat 31. The first rotary motor 52 and the transition connection seat 51, as well as the transition connection seat 51 and the bearing seat 31 are tightened and fixed by means of screws. The torque released by the first rotary motor 52 in the running state is transmitted to the rotating shaft 33 via the yaw transmission mechanism 53, so that the clamping fixture 4 and the ceramic yarn guide can synchronously perform reciprocating yaw motion.

[0045] Depend on Figure 7 , 8It can also be clearly seen from the figure that the deflection transmission mechanism 53 is mainly assembled by a rotating disk 531, a bolt curve roller bearing 532, a deflection member 533, a mounting column 534, a sector gear 535 and a cylindrical gear 536. Among them, the cylindrical gear 536 is mounted on the rotating shaft 33 as a whole and is located directly below the clamping fixture 4. After the cylindrical gear 536 is mounted in place relative to the rotating shaft 33, it is tightened and locked by means of a transverse screw to fix the two as a whole. A strip-shaped sliding guide notch 5331 that is compatible with the bolt curve roller bearing 532 is formed on the deflection member 533. The mounting column 534 serves as the mounting base of the deflection member 533, and it is inserted into the top wall of the transition connection seat 51 in an upright state. The sector gear 535 meshing with the cylindrical gear 536 is fixed to the deflection member 533 in a detachable manner. The rotating disk 531 is fixed to the main shaft of the first rotating motor 52 in a detachable manner, and performs circumferential rotation under the action of the rotational torque from the first rotating motor 52. The bolt curve roller bearing 532 uses the rotating disk 531 as an installation base, and follows the rotating disk 531 to perform circumferential rotation. At the same time, the bolt curve roller bearing 532 performs reciprocating sliding motion along the strip sliding guide notch 5331, the deflection member 533 and the fan gear 535 perform reciprocating deflection motion synchronously, and the ceramic yarn guide also performs follow-up deflection motion. The bolt curve roller bearing 532 (such as Fig.10 The roller (shown in the figure) is a high-precision bearing element widely used in the industrial field. It has a unique design structure and is usually a full-component roller design, which means that many rollers are closely arranged inside the roller to provide strong support and stability.

[0046] During the wire drawing and polishing process, the rotating disk 531 together with the bolt curve roller bearing 532 performs circumferential rotational motion due to the rotational torque from the first rotating motor 52. At the same time, the bolt curve roller bearing 532 performs sliding motion along the strip sliding guide notch 5331, and the deflection member 533 is able to perform deflection motion with the central axis of the mounting column 534 as a reference. The fan gear 535 that performs the follow-up deflection motion transmits the rotational torque to the cylindrical gear 536 through tooth meshing, and the clamping tool 4 is able to follow the rotating shaft 33 to repeatedly perform circumferential rotational motion (i.e. deflection motion) within the set angle range.

[0047] like Fig. 9 As shown in FIG. 5 , a plug-in hole 5311 is formed on the rotating disk 531 for inserting the bolt curve roller bearing 532. The number of the plug-in holes 5311 is 12, and the radial distance values ​​formed relative to the central axis of the rotating disk 531 are r1, r2, ..., r 12 , then r1, r2, ..., r 12are not equal. With respect to the central axis of the rotating disk 531, the bolt curve roller bearings 532 inserted at different positions have completely different circumferential rotation paths. Under the synergistic effect of the bolt curve roller bearings 532 and the strip sliding guide notch 5331, the deflection member 533 has completely different deflection amplitudes and deflection speeds. In practical applications, workers can quickly and efficiently adjust the insertion position of the bolt curve roller bearings 532 to cater to the yarn guide grooves of ceramic yarn guides with different design structures, ensuring that the surface roughness of the yarn guide grooves meets the expected requirements after wire drawing and polishing.

[0048] It is known that according to common knowledge, the tension of the polishing wire 64 has a crucial influence on the efficiency and quality of wire drawing polishing. If the tension of the polishing wire 64 is lower than the reasonable range, it is difficult for it to achieve close contact with the wire guide groove, which will inevitably affect the polishing efficiency, and the surface roughness after polishing will be difficult to meet the expected requirements; if the tension of the polishing wire 64 is higher than the reasonable range, it will remain in a high tensile stress state for a long time, which will lead to accidental breakage from time to time. What's worse, the single grinding amount is too large, which can easily form scratches and grooves on the surface of the wire guide groove, and it is difficult to eliminate them simply by relying on the wire drawing polishing process. In view of this, as a further optimization of the above technical solution, such as Figure 3 As shown in , the slide 2 is also equipped with a self-tensioning unit 24. The self-tensioning unit 24 is mainly assembled from several parts such as a weight 241, a fixed pulley 242 and a pulling rope 243. The fixed pulley 242 is fixedly installed at the tail of the bottom plate 21 and completely extends beyond the machine 1. The two ends of the pulling rope 243 are respectively connected to the weight 241 and the sliding plate 22, and the direction of the force is changed by winding around the fixed pulley 242. The weight 241 is in a free hanging state, and uses its own weight to apply a constant pulling force to the sliding plate 22 through the pulling rope 243. Under the action of the self-tensioning unit 24, the sliding plate 22 is continuously subjected to the pulling force, and the drawing and polishing force applied to the ceramic yarn guide by the drawing and polishing mechanism 6 at different polishing stages tends to a constant value.

[0049] Finally, the present invention also discloses a method for forming a ceramic yarn guide blank, which comprises the following steps, specifically:

[0050] 1) using a forming mold to dry-press the ceramic powder into a blank, and placing the blank in a high-temperature furnace for high-temperature sintering to form a ceramic yarn guide blank;

[0051] 2) forming a yarn guide groove on the ceramic yarn guide blank by machining;

[0052] 3) Transfer the ceramic yarn guide blanks to the polishing workshop, clamp them one by one on the clamping tooling, and confirm the alignment of the polishing wire relative to the yarn guide groove;

[0053] 4) The wire drawing and polishing equipment is started. At the same time, the ceramic yarn guide follows the clamping fixture to perform reciprocating oscillation motion, and the polishing wire passes through the yarn guide groove according to the predetermined trajectory until the surface roughness of the yarn guide groove meets the design requirements.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
