Description

Technical Field

[0001] This invention relates to the field of CNC tool grinding technology, specifically a high-precision CNC tool grinding machine. Background Technology

[0002] CNC tool grinding machines are machine tools that use CNC technology to perform precision grinding on metal cutting tools. When machining cutting tools, CNC tool grinding machines need to clamp and fix the cutting tools, which requires the use of dual spindle heads. The dual spindle heads are usually symmetrically installed on both sides of the machine tool bed, forming a horizontal or vertical opposing structure. During use, the spindle heads cause wear on the bearing raceways due to long-term high-speed heavy-load cutting.

[0003] Traditional CNC tool grinders, when driving the spindle to rotate rapidly, do not easily deliver lubricant to the spindle periphery automatically, and do not easily lubricate and cool the spindle automatically. At the same time, traditional spindles are not easy to disassemble and replace. When the bearing balls wear out, the entire bearing needs to be disassembled and replaced, which is inconvenient for quick disassembly and assembly, and it is not convenient to replace any individual ball.

[0004] Therefore, a high-precision CNC tool grinder is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision CNC tool grinding machine. This device uses multiple balls to provide rolling support between the support sleeve and the fixed frame, reducing the friction surface of the spindle during rotation. At the same time, the spindle automatically delivers lubricant to lubricate and cool the balls during rotation, and automatically circulates the lubricant. When the balls wear out, quick disassembly and assembly operations can be performed, facilitating the disassembly and maintenance of the balls, and allowing for easy disassembly and replacement of any single ball.

One end of the conveying groove and the return groove are connected to the lubrication cavity, and the connection position is located on both sides of the ball body. The two fixed frames are respectively fixedly connected to the fixed box with a conveying pipe and a return pipe. The other end of each conveying groove is connected to a conveying pipe, and the other end of each return groove is connected to a return pipe. A fan blade ring is fixedly installed on the periphery of the support ring. Two sets of fixed plates are fixedly connected to the inner wall of each fixed frame. Each set of fixed plates is circular, and every two sets of fixed plates are located on both sides of a fan blade ring.

[0010] Preferably, a first sealing ring is fixedly installed on the other side of the support ring, a first sealing plate that mates with the first sealing ring is fixedly connected to the inner wall of the fixing frame, a second sealing ring is fixedly connected to one side of the support sleeve, a fixing ring is fixedly installed at one end of each fixing frame, and a second sealing plate that mates with the ball body is fixedly connected to the inner side of each fixing ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the machining of cutting tools, the present invention fixes the cutting tool on one side of the fixed plate, and then drives the spindle to rotate rapidly, simultaneously driving the cutting tool to rotate rapidly for grinding. When the spindle rotates rapidly, it can drive the support ring and support sleeve to rotate rapidly in sync, so that the support ring and support sleeve rotate rapidly along the inside of the fixed frame. The ball bearings provide rolling support for the fixed frame, support ring, and support sleeve, which can make the spindle rotate stably and rapidly. The lubricant is stored in the fixed box, and the lubricant can be automatically introduced into the lubrication cavity through the delivery pipe and delivery groove, so that the lubricant flows downward along the inside of the lubrication cavity. When the lubricant fills the lubrication cavity, the lubricant is introduced into the return pipe through the return groove, which can make the lubricant fully lubricate and cool the ball bearings, support sleeve, support ring, and fixed frame, avoid high temperature, and reduce the degree of wear during rotation.

[0018] 2. In another embodiment of the present invention, a fan blade ring is fixed to the periphery of the support ring, and a fixing plate is fixedly connected to the inner wall of the fixing frame. The fixing plate is located on both sides of the fan blade ring. The fixing plate can restrict the lubricant, reducing the effect of the support ring rotating to drive the lubricant to rotate, so that the lubricant cannot rotate synchronously with the support ring. When the support ring rotates, it can drive the fan blade ring to rotate synchronously. The rotation of the fan blade ring can transport the lubricant outward along the lubrication cavity, and then the lubricant flows back to the inside of the fixing box through the return groove and return pipe. At the same time, the lubricant inside the fixing box is sucked into the lubrication cavity through the delivery pipe and delivery groove, so that the main shaft automatically circulates and delivers the lubricant when rotating. This can fully perform heat dissipation, cooling and lubrication operations between the ball body, support sleeve, support ring and fixing frame.

[0019] 3. As another embodiment of the present invention, by removing the bolts on the flange, the fixing bracket can be pulled out and moved along the fixing cylinder, allowing the fixing bracket to gradually extend beyond the outside of the fixing cylinder, making it easy to remove the fixing bracket from the machine tool body. By inserting the fixing bracket into the inside of the fixing cylinder, and simultaneously extending the limiting plate to the inside of the slide groove and sliding along the slide groove, and then fully inserting the fixing bracket into the inside of the fixing cylinder, the flange and the fixing cylinder are fixed with bolts, which facilitates the installation of the fixing bracket. By using the limiting plate located inside the slide groove, the slide groove can limit the limiting plate and simultaneously limit the fixing bracket, preventing the fixing bracket from rotating or shaking.

[0020] 4. As another embodiment of the present invention, after the fixing bracket is removed from the fixing cylinder, the two fixing rings are then separated, so that the two fixing rings are separated from the two fixing brackets respectively, and the second sealing plate is separated from the second sealing ring. Then, the two fixing brackets are separated, and the first sealing plate is separated from the first sealing ring, which facilitates the removal of the ball body. By rotating and removing the anti-slip nut on the fixing rod, the second sealing ring and the support sleeve can be moved outward and removed, so that the second sealing ring is separated from the main shaft, which facilitates the disassembly operation. By clamping the two fixing brackets on the outside of the support ring and fixing them to each other, and by interleaving the first sealing plate and the first sealing ring, it is easy to install and fix the fixing brackets. By placing the ball body between the support ring and the fixed frame, and then putting a support sleeve around the outside of the main shaft, the ball body between the support ring and the fixed frame can be automatically limited and supported. Then, the ball body and the support sleeve are placed around the outside of the main shaft in sequence. The support sleeve and the fixed frame can limit and support multiple ball bodies, so that the ball body rolls and supports the fixed frame and the support sleeve. Then, two fixed rings are fixed to one end of the fixed frame, so that the fixed rings are located around the outside of the main shaft. When fixed, the second sealing plate and the second sealing ring can be interlocked to seal the lubrication cavity, which facilitates assembly, allows for easy disassembly and installation of the main shaft, and facilitates the disassembly and replacement of any individual ball body.

Detailed Implementation

[0030] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and 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, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] Please see Figures 1 to 8The present invention preferably provides the following technical solution: a high-precision CNC tool grinding machine, comprising: a frame; and two rotating components rotatably mounted inside the frame, the two rotating components being symmetrically arranged on both sides of the frame; each rotating component is provided with a conveying component and a disassembly component; the frame includes a machine tool body 1, and two fixed cylinders 3 fixedly mounted inside the machine tool body 1; the rotating components include a spindle 6 and a support ring 7 fixedly connected to the periphery of the spindle 6, two fixed frames 4 are fixedly mounted on the inner side of each fixed cylinder 3, and each support ring 7 is located inside the two fixed frames 4 and rotatably connected to the fixed frames 4; a conveying assembly. The components include a fixed box 2 fixedly installed on the top of the machine tool body 1; and a disassembly assembly, including fixed rods 8. Multiple fixed rods 8 are fixedly connected to one side of the support ring 7. The fixed cylinder 3 is cylindrical, and two fixed cylinders 3 are symmetrically fixed on both sides of the inner wall of the machine tool body 1. The fixed frame 4 is arc-shaped, and two fixed frames 4 are snapped together to form a cylindrical shape. Every two fixed frames 4 are fixed in a cylindrical shape and installed inside a fixed cylinder 3. The support ring 7 and the fixed frame 4 are rotatably connected. The spindle rod 6 is fixedly connected to the outer periphery of the support ring 7. Therefore, each support ring 7 is rotatably connected to the inner side of the cylinder formed by the two fixed frames 4.

[0033] like Figure 1 , 2 As shown, by fixing the cutting tool that needs to be ground to one end of the spindle 6, and by driving the spindle 6 to rotate rapidly, the cutting tool can be rotated rapidly in sync, which can facilitate the grinding of the cutting tool.

[0034] Lubricant is introduced into the fixed box 2. When the main spindle 6 rotates rapidly, the lubricant inside the fixed box 2 can be automatically delivered to the inside of the fixed frame 4. The lubricant can automatically lubricate and dissipate heat between the fixed frame 4 and the support ring 7 when the main spindle 6 rotates rapidly, avoiding high temperature or severe wear between the fixed frame 4 and the support ring 7. At the same time, the main spindle 6 can circulate and deliver the lubricant when it rotates rapidly.

[0035] Furthermore, a rotating rod 302 is rotatably mounted on the inner side of each fixed cylinder 3. A support base 304 is fixedly mounted inside the fixed cylinder 3 at one end of each rotating rod 302. One end of each rotating rod 302 passes through a support base 304 and is rotatably connected to the support base 304. A servo motor 303 is fixedly mounted on the outer side of each of the two fixed cylinders 3. The other end of each rotating rod 302 extends out of a fixed cylinder 3 and is fixedly connected to the shaft of a servo motor 303. A gear ring 602 is fixedly mounted on the outer side of each of the two main shafts 6. The two gear rings 602 extend into the interior of the two fixed cylinders 3 and mesh with the gear disk 305. A fixed disk 601 is fixedly connected to the inner side of each of the two main shafts 6. The two fixed disks 601 are arranged coaxially and symmetrically.

[0036] like Figure 4 , 5 As shown, the cutting tool can be clamped and fixed by the fixed plate 601. By starting the servo motor 303, the servo motor 303 drives the rotating rod 302 to rotate, which in turn drives the gear disk 305 to rotate synchronously. The support base 304 supports one end of the rotating rod 302, which can make the rotating rod 302 rotate smoothly and quickly. A gear ring 602 is fixed to one end of the spindle rod 6. At the same time, the gear ring 602 meshes with the gear disk 305, which can drive the spindle rod 6 to rotate synchronously when the gear disk 305 rotates. The fixed plate 601 synchronously drives the cutting tool to rotate quickly, which is convenient for grinding the cutting tool.

[0037] Example 2

[0038] In another embodiment of the present invention, a plurality of support sleeves 703 are fixedly connected to one side of the support ring 7. The plurality of support sleeves 703 are all located on the periphery of the main shaft 6 and fit against the main shaft 6. A lubrication cavity 707 is provided between the fixing frame 4 and the support sleeves 703. A plurality of ball bodies 705 are provided on the inner side of the lubrication cavity 707. The plurality of ball bodies 705 provide rolling support between the fixing frame 4, the support sleeves 703 and the support ring 7. A plurality of fixing rods 8 pass through the plurality of support sleeves 703.

[0039] like Figure 2 , 3 As shown in Figures 5 and 6, when the main shaft 6 rotates rapidly, it can drive the support ring 7 and the support sleeve 703 to rotate synchronously and rapidly. The rolling support between the fixed frame 4 and the support sleeve 703 is provided by the ball body 705, which can make the rotation of the main shaft 6 more stable.

[0040] Example 3

[0041] In another embodiment of the present invention, the fixed frame 4 at the top of the two support rings 7 is provided with a conveying groove 403 and a return groove 404. One end of the conveying groove 403 and the return groove 404 are connected to the lubrication cavity 707, and the connection position is located on both sides of the ball body 705. The two fixed frames 4 and the fixed box 2 are respectively fixedly connected with a conveying pipe 203 and a return pipe 204. The other end of each conveying groove 403 is connected to a conveying pipe 203, and the other end of each return groove 404 is connected to a return pipe 204. A fan blade ring 702 is fixedly installed on the periphery of the support ring 7. Two sets of fixed plates 406 are fixedly connected to the inner wall of each fixed frame 4. Each set of fixed plates 406 is circular, and every two sets of fixed plates 406 are located on both sides of a fan blade ring 702.

[0042] like Figure 5 , 6As shown in Figure 7, by storing the lubricant in the fixed box 2, and connecting the fixed box 2 and the lubrication cavity 707 through the delivery pipe 203 and the delivery trough 403, the lubricant in the fixed box 2 can be introduced into the lubrication cavity 707 through the delivery pipe 203 and the delivery trough 403, and then the lubricant flows down the lubrication cavity 707 and gradually fills the lubrication cavity 707.

[0043] When the lubrication chamber 707 is filled with lubricant, the ball body 705 is fully immersed in the lubricant. The lubricant can lubricate and cool the ball body 705, the support sleeve 703 and the fixed frame 4, so as to avoid the main shaft 6 from generating high temperature and large friction between the support sleeve 703 and the fixed frame 4 when rotating, thus avoiding high temperature or severe wear.

[0044] The fixed plate 406 restricts the lubricant, reducing the effect of the support ring 7 rotating and causing the lubricant to rotate. This prevents the lubricant from rotating synchronously with the support ring 7. The support ring 7 rotates synchronously with the fan blade ring 702, which in turn transports the lubricant outward along the lubrication chamber 707. The lubrication chamber 707 then flows back into the fixed box 2 through the return groove 404 and return pipe 204. Simultaneously, the lubricant inside the fixed box 2 is drawn into the lubrication chamber 707 through the delivery pipe 203 and delivery groove 403. This allows the main shaft 6 to automatically circulate and transport the lubricant during rotation, effectively facilitating heat dissipation, cooling, and lubrication between the ball body 705, support sleeve 703, and fixed frame 4.

[0045] Example 4

[0046] In another embodiment of the present invention, a first sealing ring 701 is fixedly installed on the other side of the support ring 7, a first sealing plate 407 that cooperates with the first sealing ring 701 is fixedly connected to the inner wall of the fixing frame 4, a second sealing ring 706 is fixedly connected to one side of the support sleeve 703, a fixing ring 5 is fixedly installed at one end of each fixing frame 4, and a second sealing plate 501 that cooperates with the ball body 705 is fixedly connected to the inner side of each fixing ring 5.

[0047] like Figure 5 , 6 As shown in Figure 7, when the main shaft 6 drives the support ring 7 to rotate rapidly, it can drive the first sealing ring 701 and the second sealing ring 706 to rotate rapidly and synchronously. Through the staggered insertion of the first sealing plate 407 and the first sealing ring 701, and the staggered insertion of the second sealing plate 501 and the second sealing ring 706, the first sealing ring 701 and the second sealing ring 706 can seal both ends of the lubrication cavity 707 without affecting the rotation of the main shaft 6 and the support ring 7.

[0048] Example 5

[0049] In another embodiment of the present invention, each pair of fixing frames 4 and each pair of fixing rings 5 ​​are fixedly connected by a plurality of fixing bolts 502.

[0050] like Figure 5 As shown, by unscrewing the fixing bolts 502 on the two fixing rings 5, it is easy to separate the two fixing rings 5, so that the two fixing rings 5 ​​can be moved outward and separated from the fixing frame 4. Then, the fixing bolts 502 on the two fixing frames 4 can be unscrewed and removed, so that the two fixing frames 4 can be disassembled and separated, which is convenient for the fixing frame 4 and the main shaft 6 to be disassembled and separated.

[0051] When the fixing bolt 502 is used to fix the two fixing frames 4 and the two fixing rings 5, the fixing bolt 502 can be hidden inside the fixing frame 4 or the fixing ring 5, so as to avoid the fixing bolt 502 affecting the rotation of the main shaft 6.

[0052] Example 6

[0053] In another embodiment of the present invention, an inner ball groove 704 is provided between each pair of support sleeves 703 and between the support sleeve and the support ring 7, and an outer ball groove 405 is provided on the inner side of each fixing frame 4. Multiple ball bodies 705 are located inside the multiple inner ball grooves 704 and outer ball grooves 405 respectively, and provide rolling support for the inner ball grooves 704 and outer ball grooves 405.

[0054] like Figure 5 , 6 As shown, the inner ball groove 704 allows the support sleeve 703 to limit the rolling of the ball body 705, and the outer ball groove 405 allows the fixing frame 4 to limit the rolling of the ball body 705, so that the ball body 705 is always located inside the inner ball groove 704 and the outer ball groove 405 when rolling, thus preventing the ball body 705 from moving or misaligning.

[0055] Example 7

[0056] In another embodiment of the present invention, a flange 402 is fixedly installed on the periphery of each fixing frame 4. The flange 402 is located on one side of the fixing cylinder 3 and is fixedly connected to the fixing cylinder 3. Two sliding grooves 301 are opened on the inner side of each fixing cylinder 3. A limiting plate 401 is fixedly connected to the outer side of each fixing frame 4. Each limiting plate 401 is located inside a sliding groove 301 and is slidably connected to the sliding groove 301.

[0057] like Figure 4 , 5As shown in Figures 6, 7, and 8, by removing the bolts on the flange 402, the fixing between the flange 402 and the fixed cylinder 3 can be released. By pulling the flange 402 to move it, the fixed frame 4 can be moved synchronously, making it easy to pull the fixed frame 4 out from the inside of the fixed cylinder 3, so that the fixed frame 4 gradually extends outward along the fixed cylinder 3 and separates from the fixed cylinder 3.

[0058] By inserting the fixing bracket 4 into the inner side of the fixing cylinder 3, and then pushing the fixing bracket 4 to move into the inner side of the fixing cylinder 3, while aligning the limiting plate 401 with the slide groove 301, the limiting plate 401 can be moved to the inner side of the slide groove 301 and slide along the slide groove 301. By pushing the fixing bracket 4 to fully extend into the inner side of the fixing cylinder 3, the limiting plate 401 can be fully moved to the inner side of the slide groove 301, while driving the gear ring 602 to move to the appropriate position and mesh with the gear disk 305.

[0059] By using bolts to fix the flange 402 to the fixed cylinder 3, the fixed frame 4 is simultaneously fixed to the fixed cylinder 3. The sliding groove 301 can be used to limit and support the limiting plate 401, and simultaneously limit and support the fixed frame 4, so as to prevent the fixed frame 4 from rotating or shaking.

[0060] Example 8

[0061] In another embodiment of the present invention, each support sleeve 703 and the second sealing ring 706 are provided with a plurality of fixing holes 708 on their inner sides, and a plurality of fixing rods 8 pass through the support sleeve 703 and the second sealing ring 706 through the plurality of fixing holes 708; one end of each fixing rod 8 is fixed with an external thread 801, and an anti-slip nut 802 is threaded to the outer side of each external thread 801.

[0062] like Figure 6 , 8 As shown, all ball bodies 705 can be removed by disassembling and removing the two retainers 4 from the periphery of the spindle 6;

[0063] During installation, the anti-slip nut 802 is rotated off the external thread 801. Then, the second sealing ring 706 and multiple support sleeves 703 are moved to the right and removed, separating the second sealing ring 706 and support sleeves 703 from the main shaft 6. Two fixing brackets 4 are fixed to the periphery of the support ring 7, allowing the first sealing plate 407 and the first sealing ring 701 to interlock. The ball body 705 is then placed inside the fixing bracket 4, positioned on the periphery of the support ring 7. This allows the ball body 705 to move to the inner ball groove 704 on one side of the support ring 7, where it, in conjunction with the outer ball groove 405, provides limiting support for the ball body 705. Finally, a support sleeve 703 is fitted around the main shaft 6, allowing multiple fixing rods 8 to pass through the support. The support sleeve 703 is then pushed to move along the outer periphery of the main shaft 6 and fit against the support ring 7, which can limit and support the ball body 705. By fitting the support sleeve 703 and the second sealing ring 706 around the outer periphery of the main shaft 6 in one go, the ball body 705 is placed between every two support sleeves 703, which facilitates the installation of the ball body 705. Finally, the anti-slip nut 802 is screwed to the outer periphery of the external thread 801, so that the anti-slip nut 802 moves along the fixed rod 8 and squeezes the second sealing ring 706, simultaneously squeezing multiple support sleeves 703, so that the second sealing ring 706 and multiple support sleeves 703 are squeezed and fitted together, which facilitates assembly, and allows for easy disassembly and installation operations. Any ball body 705 can be disassembled and replaced individually.

One end of the fixed pipe 201 and the drain pipe 202 are both connected to the fixed box 2.

[0066] like Figure 1 As shown, by pulling the movable door 101, the machine tool body 1 can be easily opened and closed. The fixed pipe 201 facilitates the introduction of lubricant into the fixed box 2 for storage, and the drain pipe 202 can drain the lubricant stored in the fixed box 2.

For example, they can refer to a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.
