Description

Technical Field

[0001] This invention belongs to the field of end-face grinding and polishing technology, specifically relating to a device for grinding and polishing end faces. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece.

[0003] Currently, the grinding and polishing of the end face of ceramic rods all use dedicated grinding and polishing equipment. Existing grinding and polishing equipment is equipped with a rotatable polishing block and a clamping device. The clamping device is used to hold the ceramic rod, and the polishing block is rotatably set on the top of the clamping device. After the ceramic rod is placed on the clamping device, the height of the polishing block is controlled so that the end face of the polishing block and the end face of the ceramic rod are in contact. Then, the polishing block is controlled to rotate, so that the polishing block grinds and polishes the end face of the ceramic rod.

[0004] Specifically, when grinding and polishing the end face of a ceramic rod, the clamping device is usually provided with a slot that matches the ceramic rod. The ceramic rod is placed in the slot, which restricts its movement, thereby enabling the polishing block to grind and polish the ceramic rod.

[0005] However, in the actual process of grinding and polishing ceramic rods with polishing blocks, the grinding and polishing effect depends not only on the contact force between the ceramic rods and the polishing blocks, but also on the linear velocity of the polishing blocks on the ceramic rods. Since the positions of each ceramic rod are at different distances from the central axis of the polishing blocks, the linear velocities of each ceramic rod's position projection onto the surface of the polishing blocks are also different. This results in different forces exerted on each ceramic rod by the linear velocity of the polishing blocks, ultimately causing the grinding and polishing effects of each ceramic rod to be different, making it impossible to guarantee the grinding and polishing effect of each ceramic rod. Summary of the Invention

[0006] To address the problem that in existing ceramic rod grinding and polishing processes, the different positions of each ceramic rod from the central axis of the polishing block result in varying linear velocities when projected onto the surface of the polishing block, leading to inconsistent forces exerted on each rod by the polishing block and ultimately inconsistent grinding and polishing effects. Therefore, this invention provides a grinding and polishing device for end faces.

[0011] As a preferred embodiment of the present invention, a plurality of clamping disks are provided, and the plurality of clamping disks are arranged at equal angles around the central axis of the fixed disk within the fixed disk.

[0012] As a preferred embodiment of the present invention, the rotating assembly includes a rotating motor, a rotating main wheel, a plurality of rotating units and a rotating disk. The rotating motor is disposed at the bottom of the polishing frame. The rotating main wheel and the output end of the rotating motor are coaxially connected. The rotating disk is disposed on the polishing frame. The rotating disk has a plurality of rotating slots. The plurality of rotating slots correspond to and match a plurality of rotating units. Any rotating unit is disposed on the corresponding rotating slot. A number of rotating units are matched with a number of clamping disks. Each rotating unit is connected to a corresponding clamping disk. The rotating unit includes a rotating roller and a rotating support roller. The rotating roller is rotatably and vertically arranged in a corresponding rotating slot. The two ends of the rotating roller are coaxially connected to the rotating support roller and the clamping disk, respectively. The rotating support roller is meshed with the rotating main wheel.

[0013] As a preferred embodiment of the present invention, the clamping disk includes a hollow clamping shell, a plurality of clamping blocks, a clamping driven wheel, and a plurality of clamping driving wheels. The clamping shell is rotatably disposed within the fixed disk. The plurality of clamping blocks are vertically disposed within the clamping shell at equal angles around the central axis of the clamping shell. The clamping blocks are connected to the clamping shell and are rotatably disposed within the clamping shell. The top of the clamping block is coaxially provided with the placement slot. The clamping driven wheel is connected to the fixed disk and is coaxially disposed within the clamping shell. The plurality of clamping driving wheels are correspondingly matched with the plurality of clamping blocks. Any clamping driving wheel is coaxially disposed at the bottom of the corresponding clamping block. The clamping driving wheel is meshed with the clamping driven wheel. The rotating roller is coaxially connected to the clamping shell to control the rotation of the clamping shell.

[0014] As a preferred embodiment of the present invention, the bottom of the clamping housing is coaxially provided with a through groove, the clamping driven wheel is coaxially disposed in the clamping housing through the through groove, the clamping driven wheel is coaxially provided with a hollow groove, and the rotating roller coaxially passes through the through groove and the hollow groove and is connected to the top of the clamping housing.

The grinding end face of the polishing disc grinds and polishes the top surface of the workpiece. The rotating assembly controls the rotation of the clamping disc, causing each workpiece to rotate along the central axis of the clamping disc. This changes the position of each workpiece projected onto the grinding end face of the polishing disc. Viewed along the diameter of the polishing disc, the position of each workpiece projected onto the grinding end face of the polishing disc repeatedly moves back and forth along any diameter axis of the polishing disc, thus ensuring that each workpiece on the polishing disc... The grinding trajectory is the same, eliminating the uneven grinding and polishing caused by the difference in linear velocity on the surface of the polishing pad. Ultimately, it ensures that the polishing amount of all polished parts is consistent. This solves the problem that in the existing grinding and polishing process, the position of each part to be polished is different from the central axis of the polishing block, so the linear velocity of the position of each part to be polished when projected onto the surface of the polishing block is also different. As a result, the force exerted by the linear velocity of the polishing block on each part to be polished is also different, which ultimately leads to different grinding and polishing effects for each part to be polished and makes it impossible to guarantee the grinding and polishing effect of each part.

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0022] Please see Figures 1-10This embodiment provides a grinding and polishing device for end faces, including a polishing frame 1 and a polishing assembly 2, a clamping disk 3, a hollow fixed disk 4, and a rotating assembly 7 disposed on the polishing frame 1. The polishing assembly 2 includes a rotatable polishing disk 201. The fixed disk 4 is disposed on the polishing frame 1, and the clamping disk 3 is disposed at one end of the fixed disk 4 around its central axis. It should be noted that the central axis of the clamping disk 3 and the central axis of the fixed disk 4 are parallel to each other but do not coincide. The clamping disk 3 has a placement slot 3021 for placing the workpiece to be polished. A plurality of placement slots 3021 are arranged at equal angles along the central axis of the clamping disk 3. A plurality of polishing parts are correspondingly matched with the plurality of placement slots 3021, and any polishing part is placed in the corresponding placement slot 3021. The polishing disk 201 is coaxially arranged on the fixed disk 4, and the grinding end face of the polishing disk 201 is fitted with the end face of the workpiece to be polished. The rotating component 7 is connected to the clamping disk 3 and controls the clamping disk 3 to rotate. The rotation direction of the clamping disk 3 is opposite to the rotation direction of the polishing disk 201. By providing the rotating component 7, when the device starts to run, the polishing disk 201 and the rotating component 7 move together. During operation, the grinding end face of the polishing disc 201 can grind and polish the top surface of the workpiece. Meanwhile, the rotating component 7 controls the rotation of the clamping disc 3, causing each workpiece to rotate along the central axis of the clamping disc 3. This changes the position of each workpiece projected onto the grinding end face of the polishing disc 201. Viewed along the diameter of the polishing disc 201, the position of each workpiece projected onto the grinding end face of the polishing disc 201 repeatedly moves back and forth along any diameter axis of the polishing disc 201, thus ensuring that the grinding trajectory of each workpiece on the polishing disc 201 is consistent. Similarly, this method eliminates the uneven grinding and polishing caused by the difference in surface linear velocity of the polishing disc 201, ultimately ensuring that the polishing amount of all polished parts is consistent. This solves the problem that in the existing grinding and polishing process, the distance between each part and the central axis of the polishing block is different, resulting in different linear velocities when the position of each part is projected onto the surface of the polishing block. Consequently, each part experiences different forces from the linear velocity of the polishing block, leading to inconsistent grinding and polishing effects and making it impossible to guarantee the grinding and polishing effect of each part.

[0023] It should be noted that the solution to the problem of the workpiece to be polished is also applicable to the problem of grinding and polishing the top surface of ceramic rods. Furthermore, the rotation direction of the clamping disk 3 is opposite to that of the polishing disk 201 to ensure that the rotation of the clamping disk 3 does not weaken the grinding and polishing effect of the polishing disk 201 on the workpiece to be polished.

[0024] Furthermore, in order to facilitate the insertion of the workpiece to be polished into the corresponding placement slot 3021, it is necessary to control the movement of the polishing disc 201 in advance to release the alignment between the central axis of the polishing disc 201 and the central axis of the fixed disc 4. Based on this, the polishing assembly 2 of this solution also includes a moving unit 5. The moving unit 5 includes a moving cylinder 501 and a moving frame 502. The moving frame 502 is slidably mounted on the polishing frame 1. The moving cylinder 501 is mounted on the polishing frame 1. The output end of the moving cylinder 501 is connected to the moving frame 502 to control the movement of the moving frame 502. The polishing disc 201 is mounted on the moving frame 502. The central axis of the polishing disc 201 can be locked or released from its alignment with the central axis of the fixed disc 4. By providing a movable cylinder 501, when the movable cylinder 501 starts working, it controls the movable frame 502 to move, which in turn drives the polishing disc 201 connected to the movable frame 502 to move, ultimately realizing the mutual overlap between the central axis of the polishing disc 201 and the central axis of the fixed disc 4, making it convenient for the staff to insert the workpiece to be polished into the corresponding placement slot 3021; ​​after the workpiece to be polished is inserted into the corresponding placement slot 3021, the movable frame 502 is reset.

[0025] Furthermore, in order to achieve the lifting control of the polishing disc 201, the polishing assembly 2 of this solution also includes a lifting rod 202 and a rotating unit 6. The lifting rod 202 is vertically mounted on the movable frame 502, and the rotating unit 6 is coaxially connected to the polishing disc 201. The output end of the lifting rod 202 is connected to the rotating unit 6 to control the height of the polishing disc 201.

[0026] Furthermore, in order to control the rotation of the polishing disc 201, the rotating unit 6 of this solution includes a rotating motor 601, a rotating belt 602, a rotating wheel 603, and a rotating frame 604. The rotating frame 604 is connected to the output end of the lifting rod 202. The rotating motor 601 is mounted on the rotating frame 604, and the polishing disc 201 is rotatably mounted on the rotating frame 604. The rotating wheel 603 is coaxially mounted on the polishing disc 201. The rotating belt 602 is engaged with the output ends of the rotating wheel 603 and the rotating motor 601, respectively. The rotating motor 601 controls the rotation of the polishing disc 201 by rotating. With this arrangement, when the rotating motor 601 starts working, it can drive the rotating belt 602 engaged with the rotating motor 601 to perform transmission, and then the rotating belt 602 can drive the rotating wheel 603 to rotate, ultimately realizing the rotation of the polishing disc 201.

[0027] In addition, it should be noted that in order to perform grinding and polishing on multiple parts to be polished at the same time, this solution provides several clamping disks 3, which are arranged at equal angles around the central axis of the fixed disk 4 within the fixed disk 4.

[0028] Furthermore, in order to enable multiple clamping discs 3 to rotate simultaneously, the rotating assembly 7 of this solution includes a rotating motor 701, a rotating main wheel 702, several rotating units, and a rotating disk 703. The rotating motor 701 is located at the bottom of the polishing frame 1, and the rotating main wheel 702 is coaxially connected to the output end of the rotating motor 701. The rotating disk 703 is mounted on the polishing frame 1 and has several rotating slots. These slots correspond to several rotating units, and any rotating unit is positioned on a corresponding rotating slot. Each rotating unit is matched with a corresponding clamping disk 3. The rotating unit includes a rotating roller 704 and a rotating support roller 705. The rotating roller 704 is rotatably and vertically positioned within a corresponding rotating slot. It should be noted that the vertical and rotatable positioning of the rotating roller 704 within the corresponding rotating slot is a well-established structure and will not be elaborated upon here. Both ends of the rotating roller 704 are coaxially connected to the rotating support roller 705 and the clamping disk 3, respectively. The rotating support roller 705 is meshed with the rotating main wheel 702. It should be noted that several rotating support rollers 705 are arranged at equal angles around the central axis of the rotating main wheel 702, and are meshed with it. With this arrangement, when the rotating motor 701 starts working, it drives the rotating main wheel 702, which in turn drives the rotating support rollers 705 to rotate, ultimately causing the corresponding clamping disk 3 to rotate. Since several rotating support wheels 705 are respectively engaged with rotating main wheels 702, multiple clamping discs 3 can rotate simultaneously.

[0029] Furthermore, the device in this solution is used to grind the top end face of the ceramic rod. However, in the actual grinding process, due to the tolerances that occur during the actual manufacturing of the ceramic rod, the diameter of the placement slot 3021 is always slightly larger than the diameter of the ceramic rod by a value on the order of a few tenths of a millimeter. As a result, when the ceramic rod mates with the placement slot 3021, there will be a gap on the order of a few tenths of a millimeter between the side wall of the ceramic rod and the side wall of the placement slot 3021. When the polishing disc 201 grinds and polishes the end face of the ceramic rod, the polishing disc 201 will generate a single radial force on the ceramic rod, causing a slight tilt on the top end face of the ceramic rod. Ultimately, this results in one end of the circular edge of the ceramic rod end face being over-polished, while the other end is not polished. To address this issue, this solution requires controlling the rotation of each ceramic rod around its own central axis while the clamping disk 3 rotates. Therefore, the clamping disk 3 includes a hollow clamping housing 301, several clamping blocks 302, driven clamping wheels 303, and several driving clamping wheels 304. The clamping housing 301 is rotatably mounted within the fixed disk 4. The clamping blocks 302 are vertically arranged at equal angles within the clamping housing 301 around its central axis. The clamping blocks 302 are connected to the clamping housing 301 and are rotatably mounted within it. A placement slot 3021 is coaxially formed on the top of each clamping block 302 for clamping... Driven wheel 303 is connected to fixed disk 4, and clamping driven wheel 303 is coaxially arranged inside clamping housing 301. Several clamping driving wheels 304 are correspondingly matched with several clamping blocks 302. Any clamping driving wheel 304 is coaxially arranged at the bottom of the corresponding clamping block 302. Several clamping driving wheels 304 are arranged at equal angles around the central axis of clamping driven wheel 303 around the periphery of clamping driven wheel 303. Clamping driving wheels 304 are meshed with clamping driven wheel 303. Rotating roller 704 is coaxially connected to clamping housing 301 to control the rotation of clamping housing 301. With this arrangement, since clamping driven wheel 303 is connected to fixed disk 4, clamping driven wheel 303 itself does not rotate. When the rotating roller 704 rotates, it drives the clamping housing 301 to rotate, which in turn drives the clamping block 302 connected to the clamping housing 301 to rotate along the central axis of the clamping housing 301. Since the clamping drive wheel 304 is engaged with the clamping driven wheel 303, the clamping block 302 rotates around its own central axis while the clamping housing 301 rotates. This results in each ceramic rod rotating along the central axis of the clamping housing 301 while simultaneously rotating along its own central axis. Through this rotation, the circular edges of the ceramic rod's end face are ground and polished at all points.

[0030] Specifically, with the driven wheel 303 connected to the fixed disk 4 and the driven wheel 303 coaxially disposed within the clamping housing 301, the rotating roller 704 can also achieve coaxial connection with the clamping housing 301. In this scheme, the bottom of the clamping housing 301 is coaxially provided with a through groove, the driven wheel 303 is coaxially disposed within the clamping housing 301 through the through groove, the driven wheel 303 is coaxially provided with a hollow groove, and the rotating roller 704 coaxially passes through the through groove and the hollow groove to connect with the top inside the clamping housing 301.

[0031] Furthermore, it is worth noting that in order to ensure that the ceramic rod on the clamping block 302 can also rotate when the clamping block 302 rotates, it is necessary to ensure that the clamping block 302 can clamp the ceramic rod. Based on this, the clamping block 302 in this solution is also coaxially provided with a clamping slot 3022. The clamping slot 3022 is connected to the placement slot 3021 and is located at the bottom of the placement slot 3021. The diameter of the clamping slot 3022 decreases from top to bottom, and the maximum diameter of the clamping slot 3022 is equal to the diameter of the placement slot 3021. By providing the clamping slot 3022, the bottom of the ceramic rod can be clamped.

[0032] Furthermore, the clamping disk 3 also includes a clamping top cover 305, which is detachably fastened to the top of the clamping housing 301. The clamping top cover 305 has several connecting slots, which are arranged at equal angles around the central axis of the clamping top cover 305. The several connecting slots correspond to and match several clamping blocks 302. Any connecting slot is coaxially sleeved on the corresponding clamping block 302. The rotating roller 704 is coaxially connected to the bottom of the clamping top cover 305. By providing the clamping top cover 305, the rotating roller 704 is coaxially connected to the top of the clamping housing 301 through the coaxial connection with the bottom of the clamping top cover 305.
