Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and specifically proposes a ceramic guide wheel outer circle polishing processing equipment. Background Technology

[0002] Ceramic yarn guide wheels, due to their multiple advantages such as smooth surface, wear resistance, corrosion resistance, high temperature resistance, and antistatic properties, have become the mainstream guide wheels in the yarn textile industry. They are generally manufactured by whole-piece sintering, fine grinding of the inner and outer circles, and polishing of the yarn grooves. When polishing the outer circle of the ceramic yarn guide wheel, the focus is mainly on polishing the surface of the yarn grooves on the outer circle. Generally, both ends of the ceramic yarn guide wheel are fixedly clamped, and the rotating ceramic yarn guide wheel is polished by a polishing wheel. In existing polishing equipment, the ceramic yarn guide wheel is basically rigidly clamped and polished by contact polishing with a single polishing wheel. The above polishing method will have the following adverse effects on the polishing quality of the outer circle of the ceramic yarn guide wheel.

[0003] 1. The polishing wheel rotates at high speed, and the abrasive continuously rubs against the ceramic surface during polishing. The inherent vibrations generated by the rotation of the polishing wheel and the impact vibrations from the polishing contact are directly transmitted to the ceramic guide wheel. The inherent vibrations generated by the rotation of the main shaft of the equipment are also directly transmitted to the ceramic guide wheel due to the rigid clamping. The ceramic guide wheel itself has low damping due to the high hardness, rigidity, and brittleness of the ceramic material. It has almost no ability to absorb vibrations and is extremely sensitive to minute vibrations, even amplifying them. Vibrations will produce vibration marks and other textures on the surface of the ceramic guide wheel during polishing. If subsequent quality inspection is carried out by visual observation only, some textures are not obvious to the naked eye, which may lead to misjudgment. However, ceramic guide wheels with textures have high resistance to yarn feeding and are prone to fraying the yarn. In addition, due to their brittleness, ceramic guide wheels are not resistant to vibration and impact and are prone to developing micro-cracks inside or on the surface, which seriously affects their service life.

[0004] 2. When using a single polishing wheel for contact polishing, the ceramic guide wheel is constantly subjected to lateral force from the polishing wheel during polishing, resulting in poor polishing stability, which further enhances the adverse effect of vibration and directly affects the uniformity of polishing.

[0005] 3. Rigid clamping can also easily cause uneven wear or breakage of the ceramic yarn guide wheel. Uneven wear will cause uneven roughness on the surface of the yarn groove, and since most ceramic yarn guide wheels have thin walls, uneven wear also increases the risk of breakage. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a ceramic guide wheel outer diameter polishing processing device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention employs the following technical solution: a ceramic guide wheel outer diameter polishing processing device, comprising a rotary mechanism, a guide support, a working frame, multiple polishing mechanisms, and an adjusting mechanism; the rotary mechanism is used to float and clamp the ceramic guide wheel axially along the rotary central axis and drive the ceramic guide wheel to rotate horizontally; the working frame is horizontally slidably mounted on the guide support; the working frame can lock into the rotary mechanism in its sliding direction; multiple polishing mechanisms are circumferentially distributed around the rotary central axis of the rotary mechanism; the polishing mechanisms are used to polish the outer diameter of the ceramic guide wheel and can independently adjust the polishing pressure; the adjusting mechanism is mounted on the working frame and connected to the multiple polishing mechanisms, used to drive the multiple polishing mechanisms to move synchronously radially along the rotary central axis; when the working frame is locked into the rotary mechanism, the working frame floats axially with the ceramic guide wheel and slides synchronously, indirectly driving the multiple polishing mechanisms to move synchronously with the working frame.

[0008] Preferably, the rotary mechanism includes two rotating shafts that are horizontally rotatably mounted and coaxially arranged via rotating seats. One rotating seat is fixed, and the other rotating seat is slidably arranged along the axial direction of the rotating shaft. Each of the two rotating shafts has a floating end fixed at one of its opposite ends. The two floating ends are respectively detachably mounted with a No. 1 chuck and a No. 2 chuck, which are used to cooperate in coaxially clamping the ceramic yarn guide wheel.

[0009] Preferably, the working frame includes a sliding cylinder coaxially arranged with the rotating shaft and slidably mounted on the guide support. One end of the sliding cylinder is fixed with a mounting plate, and multiple polishing mechanisms are circumferentially distributed and mounted on the mounting plate around the central axis of the rotating shaft.

[0010] Preferably, the polishing mechanism includes a fine-tuning component, a sliding frame, a pressure sensor, an elastic slide, and a polishing component arranged sequentially along a direction close to the center of the mounting plate; the fine-tuning component and the sliding frame are slidably mounted on the mounting plate along the same radial direction of the rotating shaft, and the pressure sensor is fixed on the sliding frame; the polishing component and the pressure sensor are connected by elastic damping through the elastic slide and slide radially along the rotating shaft; the adjustment mechanism drives the fine-tuning component to slide, and the fine-tuning component drives the sliding frame to slide.

[0011] Preferably, the working frame further includes a rotary bearing; the inner ring of the rotary bearing is fixedly connected to one of the floating ends; the outer ring of the rotary bearing is slidably fitted with the inner wall of the sliding cylinder, and an expansion ring is embedded and fixed on the outer ring of the rotary bearing, which expands by inflation and presses against the inner wall of the sliding cylinder for locking.

[0012] Preferably, the adjustment mechanism includes a drive turntable rotatably mounted on a sliding cylinder; a connecting block is fixed on the sliding part of each fine-tuning component, and a connecting rod is hinged between the connecting block and the drive turntable.

[0013] Preferably, the floating end includes a mounting head, one end of which is detachably fitted with a No. 1 chuck or a No. 2 chuck, and the other end of the mounting head is provided with a spline shaft. The rotating shaft and the spline shaft are slidably fitted together. A No. 1 spring is sleeved on the spline shaft, and the two ends of the No. 1 spring are respectively fixed on the mounting head and the rotating shaft; the inner ring of the slewing bearing is sleeved and fixed on one of the mounting heads.

[0014] Preferably, the fine-tuning component includes a sliding base slidably mounted on the mounting plate and a cylinder fixed on the sliding base; a connecting block is fixed to the sliding base; and a sliding frame is fixed to the cylinder output end.

The polishing mechanism can perform real-time independent feedback closed-loop adjustment of the polishing pressure. By providing constant pressure contact support at multiple circumferential points for the ceramic yarn guide wheel, and in conjunction with axial centering clamping, the stability of polishing is improved, and alignment with the reference center axis is ensured, avoiding unilateral lateral force. This ensures the coaxiality of the inner and outer circles of the ceramic yarn guide wheel during polishing, guarantees the uniformity of polishing, and the multi-point contact polishing effectively improves polishing efficiency; multiple polishing... The optical mechanism and the floating end are connected by an unlockable working frame, which enables synchronous axial floating linkage adjustment between multiple polishing ends and ceramic guide wheels. Thus, while avoiding uneven wear and ensuring polishing alignment accuracy, the axial adaptive elastic floating and the radial elastic damping contact of the polishing mechanism can absorb and weaken vibration and impact, making up for the defect of ceramic guide wheels being unable to absorb vibration due to their high rigidity and low damping. This reduces the possibility of defects such as vibration marks caused by vibration during ceramic guide wheel polishing, ensures the polishing accuracy of the groove, avoids misjudgment in quality inspection, and also solves the problem of micro-cracks or breakage caused by the brittleness, thin walls and poor resistance to vibration and impact of ceramic guide wheels, thus ensuring the subsequent service life of ceramic guide wheels.

[0025] 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 without creative effort are within the scope of protection of the present invention.

[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1As shown, a ceramic yarn guide wheel outer circle polishing processing equipment includes a base, a rotary mechanism 1, a guide support 2, a working frame 3, three polishing mechanisms 4, and an adjustment mechanism 5. It is mainly used to polish the grooves on the outer circle of medium and large-sized ceramic yarn guide wheels 6. It should be noted that the non-groove surface of the outer circle of the ceramic yarn guide wheel 6 does not contact the yarn. Before polishing with the equipment provided by this invention, the outer circle of the ceramic yarn guide wheel 6 can be rough polished as a whole, and the non-groove surface of the outer circle can be finely ground and rough polished. In addition, the inner hole of the ceramic yarn guide wheel 6 is used to install the rotating shaft 11. The inner hole serves as the positioning reference for subsequent processing, completing the fine processing and polishing before the outer circle, and can provide a high-precision clamping reference for subsequent outer circle polishing, ensuring the coaxiality of the inner and outer circles.

[0028] like Figure 2 and Figure 5 As shown, the rotary mechanism 1 includes two horizontally rotatable and coaxially arranged rotating shafts 11 mounted on rotating seats. One rotating seat is fixed to the base by bolts, and the rotating shaft 11 on this rotating seat is the drive shaft. A geared motor is also fixed to the rotating seat by bolts, and the rotating shaft 11, serving as the drive shaft, is fixedly connected to the output shaft of the geared motor. A guide rail is welded to the base, and the other rotating seat is slidably mounted on the guide rail along the axial direction of the rotating shaft 11. The rotating shaft 11 on this rotating seat serves as the driven shaft. In addition, a hydraulic cylinder is horizontally fixed to the base by bolts, and the slidably mounted rotating seat is fixedly connected to the output end of the hydraulic cylinder by bolts. In this embodiment, a hydraulic cylinder is used to drive the rotating seat to slide, but other existing linear drive devices can also be selected. It should be noted that the base, rotating seat, and hydraulic cylinder are not shown in the figure.

[0029] like Figure 2 , Figure 3 and Figure 5As shown, each of the two rotating shafts 11 has a floating end 12 mounted on one of its opposite ends. The floating end 12 includes a cylindrical mounting head 121. A splined shaft 122 and a connector 123 are coaxially mounted on the two end faces of the mounting head 121, respectively. The splined shaft 122, connector 123, and mounting head 121 are integrally formed. The rotating shaft 11 slides with the splined shaft 122. A first spring 124 is sleeved on the splined shaft 122, with its two ends fixed to the end face of the mounting head 121 and the shaft end of the rotating shaft 11, respectively. The mounting heads 121 of the two floating ends 12 are respectively connected to a first chuck 13 and a second chuck 14 via connectors 123. Both the first chuck 13 and the second chuck 14 are connected to the connectors 123. The first chuck 13 and the second chuck 14 are used to coaxially clamp the ceramic guide wheel 6 using a key and screws. The first chuck 13 and the second chuck 14 are detachable and can be flexibly adapted and replaced to centrally clamp different models of ceramic guide wheels 6. In this embodiment, the first chuck 13 is provided with a central shaft that matches the inner hole size of the ceramic guide wheel 6. The clamping end face of the second chuck 14 is provided with a hole for the central shaft to be inserted. The first chuck 13 and the second chuck 14 are inserted relative to each other by a key. The first chuck 13 is mounted on the floating end 12 connected to the rotating shaft 11, which serves as the driving shaft, and the second chuck 14 is mounted on the floating end 12 connected to the rotating shaft 11, which serves as the driven shaft.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, the guide support 2 is fixed to the base by bolts, and a cylindrical guide sleeve 21 coaxially arranged with the rotating shaft 11 is welded onto the guide support 2; the working frame 3 includes a sliding cylinder 31 slidably installed in the guide sleeve 21 by keying, and a mounting plate 32 is welded to one end of the sliding cylinder 31, with a circular hole aligned with the inner wall of the sliding cylinder 31; a rotary bearing 33 is assembled inside the sliding cylinder 31; the inner ring of the rotary bearing 33 is sleeved and fixed on one of the mounting heads 121, and the floating end 12 including the mounting head 121 is assembled on the rotating shaft 11, which serves as the drive shaft; the outer ring of the rotary bearing 33 slides against the inner wall of the sliding cylinder 31, and an expansion ring is embedded and fixed on the outer ring of the rotary bearing 33. 331. The expansion ring 331 is made of rubber and is hollow inside. An air nozzle is fixed on the expansion ring 331 and connected to an air pipe. When the expansion ring 331 is not inflated, it is completely embedded in the inner groove of the outer ring of the slewing bearing 33. The sliding cylinder 31 and the slewing bearing 33 can slide normally relative to each other. After air is inflated into the expansion ring 331, it expands and deforms, pressing against the inner wall of the sliding cylinder 31 to complete the locking. The outer side wall surface of the expansion ring 331 is roughened. It should be noted that the locking method by the expansion ring 331 is a non-rigid locking, but according to the tests of those skilled in the art, the clamping force provided by the expansion ring 331 meets the requirements for axial locking between the slewing bearing 33 and the sliding cylinder 31.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, three slide rails 321 are welded onto the mounting plate 32, evenly distributed around the center of the circular hole. The guide direction of the slide rails 321 is radial to the circular hole. The polishing mechanism 4 is installed on the slide rails 321 one by one. The polishing mechanism 4 includes a fine-tuning component, a sliding frame 43, a pressure sensor 44, an elastic slide, and a polishing component, which are sequentially distributed along the direction close to the center of the circular hole of the mounting plate 32. The fine-tuning component includes a sliding frame 41 slidably mounted on the slide rail 321 and a cylinder 42 fixed to the sliding frame 41 by bolts. The sliding frame 43 is slidably mounted on the slide rail 321 and fixed to the output end of the cylinder 42 by bolts. The pressure sensor 44 is an existing columnar sensor specifically used for pressure detection. The fixed end of the pressure sensor 44 is fixed to the sliding frame 43 by screws. The elastic slide includes The components include a guide rod frame 45, a damper, and a second spring 47. The guide rod frame 45 is fixed to the pressure measuring end of the pressure sensor 44 by screws. The guide rod frame 45 contains two guide rods, each of which is fitted with a second spring 47. In this embodiment, the damper is a rubber damping sleeve. Both second springs 47 are fitted with damping sleeves, which are not shown in the figure. The polishing assembly includes a motor base 46. The guide rod frame 45 slides with the motor base 46 through the two guide rods. The two ends of the second spring 47 are fixed to the guide rod frame 45 and the motor base 46, respectively. The two ends of the damping sleeve are glued and fixed to the guide rod frame 45 and the motor base 46, respectively. A gap is reserved between the damping sleeve and the second spring 47. A drive motor 48 is fixed to the motor base 46 by bolts. A polishing wheel 49 is detachably fixed to the output shaft of the drive motor 48.

[0032] It should be added that the force direction of the pressure sensor 44 and the sliding direction of the guide rod frame 45 are both set along the sliding direction of the sliding frame 43. In addition, the polishing wheel 49 is an existing grinding wheel specifically used for fine polishing, including but not limited to resin grinding wheels, rubber grinding wheels, sponge grinding wheels, etc. In actual polishing, two-step operations of rough polishing and fine polishing can be selected. According to the requirements of different polishing stages, the corresponding polishing grit size and the corresponding type of polishing wheel 49 can be selected. It should also be emphasized that since the groove of the outer circle of the ceramic yarn guide wheel 6 is presented in different groove shapes such as arc R-shape, U-shape or V-shape, in order to ensure uniform contact between the polishing wheel 49 and the groove, the corresponding polishing wheel 49 can be customized for ceramic yarn guide wheels 6 with different groove sizes, so that the polishing end contour of the polishing wheel 49 is adapted to the groove shape.

[0033] In this invention, each polishing mechanism 4 can achieve independent feedback closed-loop control adjustment of polishing pressure through a constant pressure control system. Specifically, the constant pressure control system includes a sensor detection module, a central control module, and a cylinder 42 execution module. The sensor detection module collects polishing pressure in real time through a pressure sensor 44, outputs an analog signal, and performs filtering, amplification, anti-interference, and noise reduction processing on the analog signal. Then, it converts the analog signal into a digital signal and transmits it to the central control module. The central control module can preset the corresponding target polishing pressure and the allowable upper and lower fluctuation range. After receiving the digital signal of the polishing pressure, the central control module compares it with the target polishing pressure. If the real-time pressure value is within the allowable fluctuation range, the central control module maintains the current output signal unchanged, and the output of cylinder 42 remains unchanged. If the real-time pressure value is less than the minimum value of the fluctuation range, the polishing pressure is insufficient, and the central control module outputs a corresponding adjustment signal and transmits it to the cylinder 42 execution module. Cylinder 42 feeds pressure according to the adjustment amount. When the real-time pressure value is greater than the maximum value of the fluctuation range, cylinder 42 retracts to reduce pressure according to the adjustment amount. Thus, the polishing mechanism 4 achieves constant pressure closed-loop control adjustment of polishing pressure. It should be noted that the control method of this constant pressure control system is existing technology. The above descriptions of the control module composition and control logic method are brief and will not be elaborated upon here.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the adjustment mechanism 5 includes a drive turntable 51, with a bearing welded to its center. The drive turntable 51 is fitted onto the sliding cylinder 31 via the inner ring of the bearing, and the inner ring is fixed to the mounting plate 32 by bolts. Each of the sliding bases 41 of the three polishing mechanisms 4 has a connecting block 53 welded on it. The connecting block 53 passes through the mounting plate 32, and a connecting rod 52 is hinged between the connecting block 53 and the drive turntable 51. In this embodiment, a gear ring is also coaxially welded onto the drive turntable 51. A self-locking stepper motor can be fixedly mounted on the mounting plate 32 by bolts. A gear that meshes with the gear ring is fixed on the output shaft of the stepper motor. The above drive structure combination is a common drive structure setting, which is not shown in the figure.

[0035] Before polishing, with the expansion ring 331 not expanded and locked, the central shaft of the first chuck 13 is inserted into the inner hole of the ceramic guide wheel 6 to be polished. Then, the second chuck 14 is moved, and by rotating one of the rotating shafts 11, the central shaft of the first chuck 13 is aligned with the insertion hole of the second chuck 14. Then, the movement continues, and the first chuck 13 and the second chuck 14 are engaged and inserted, so that the first spring 124 of the two floating ends 12 is compressed, and the ceramic guide wheel 6 is stably clamped between the first chuck 13 and the second chuck 14.

[0036] Subsequently, the sliding cylinder 31 can be pushed to slide, thereby driving the three polishing mechanisms 4 to move upward along the axis of the rotating shaft 11 with the working frame 3, so that the polishing end of the polishing wheel 49 is aligned with the groove of the ceramic guide wheel 6; then, the stepper motor of the adjusting mechanism 5 is started, driving the drive turntable 51 to rotate, and through the connecting rod 52 and the connecting block 53, the polishing mechanism 4 is driven to slide closer to the ceramic guide wheel 6 along the slide rail 321. The polishing wheel 49 will penetrate into the groove. As it continues to slide, the second spring 47 is compressed, and the polishing wheel 49 is in close contact with the groove; the contact pressure between the polishing wheel 49 and the ceramic guide wheel 6 is indirectly transmitted through the second spring 47. The pressure sensor 44 can collect the corresponding polishing pressure in real time, and perform independent closed-loop control adjustment through the constant pressure control system. Finally, the three polishing wheels 49 maintain close contact with the ceramic guide wheel 6 with approximately the same polishing pressure; finally, the expansion ring 331 is expanded and pressed against the inner wall of the sliding cylinder 31, locking the rotary bearing 33 and the sliding cylinder 31.

[0037] In this invention, the adjustment mechanism 5, centered on the central axis of the rotating shaft 11, performs radial synchronous displacement adjustment on the three polishing mechanisms 4, ensuring the uniformity and synchronicity of the large-size feed of the three polishing mechanisms 4 under the same process reference. Each polishing mechanism 4 can also perform independent feedback control adjustment of polishing pressure, ensuring the independence of each polishing mechanism 4 in micro-size feed, thereby ensuring the constant polishing pressure of the three polishing wheels 49, avoiding the inconsistency of the polishing effect of the three polishing wheels 49. Through the constant pressure contact of the three circumferentially distributed polishing mechanisms 4 on the ceramic guide wheel 6, the ceramic guide wheel 6 is prevented from being subjected to lateral force, ensuring the force is applied to the center, improving the stability of polishing, and playing a role in suppressing vibration. At the same time, the layout of multiple polishing ends can also effectively improve polishing efficiency.

[0038] During polishing, the two rotating shafts 11 drive the ceramic guide wheel 6 to rotate, and the rotation speed of the rotating shaft 11 can be set to 600 r / min; the drive motor 48 is started to drive the polishing wheel 49 to polish the outer circular groove, and the rotation speed of the polishing wheel 49 can be set to 2000 r / min; during the polishing process, the two floating ends 12 can drive the ceramic guide wheel 6 to float slightly in the axial direction of the rotating shaft 11. With the rotary bearing 33 locked to the sliding cylinder 31, the working frame 3 can slide synchronously along the guide sleeve 21 with the floating ends 12, thereby indirectly driving the three polishing mechanisms 4 to move with the working frame 3. The synchronous floating linkage design ensures that the polishing wheel 49 is always aligned with the center of the groove without deviating to one side. Under the premise of avoiding uneven wear and ensuring polishing alignment accuracy, the axial elastic floating can absorb and weaken the vibration impact from the axial direction, avoiding the generation of micro-cracks or breakage.

[0039] Meanwhile, in the polishing mechanism 4, the polishing wheel 49 and the ceramic guide wheel 6 are in non-rigid contact through the elastic slide. The second spring 47 provides polishing pressure through its elasticity and adapts to the wear of the polishing wheel to ensure that the polishing wheel 49 is effectively pressed against the groove. It can also be used with the constant pressure control system to adjust the polishing pressure. The damper absorbs the vibration and impact generated by the polishing wheel 49 in the radial direction of the rotating shaft 11, which makes up for the defect of the ceramic guide wheel 6, which has high rigidity and low damping, and cannot absorb vibration. It reduces the possibility of defects such as vibration marks caused by vibration during the polishing of the ceramic guide wheel 6, ensures the polishing accuracy of the groove, avoids misjudgment in quality inspection, and also solves the problem of micro-cracks or breakage caused by the brittleness, thin wall and poor resistance to vibration and impact of the ceramic guide wheel 6, so as to ensure the service life of the ceramic guide wheel 6.
