Description

Technical Field

[0001] This invention relates to the field of lathe tool grinding technology, and in particular to a precision grinding device for CNC lathe tool cutting edges. Background Technology

[0002] Turning, as one of the most fundamental machining methods in the field of mechanical manufacturing, relies heavily on the condition of the cutting edge of the turning tool for its machining accuracy and surface quality. As the core cutting tool of a CNC lathe, the turning tool operates under high temperature, high pressure, and intense friction conditions, inevitably leading to wear, chipping, and other damage on its cutting edge, directly affecting the workpiece's machining quality and production efficiency.

[0003] Currently, existing tool sharpening devices typically employ a single-station clamping method, capable of clamping and sharpening only one cutting tool at a time. After each sharpening cycle, the machine must be stopped, the sharpened tool removed, and the next tool to be sharpened re-clamped. The clamping, positioning, and calibration operations involved are time-consuming, consuming significant non-machining time and resulting in low overall sharpening efficiency. This is particularly problematic in large machinery manufacturing enterprises with numerous CNC lathes, heavy machining workloads, and rapid tool wear, resulting in a substantial number of tools requiring sharpening daily. Existing single-station sharpening methods are ill-suited to meet the demands of simultaneous or continuous high-efficiency sharpening of multiple cutting tools in batches.

[0004] Therefore, this application proposes a multi-station CNC lathe tool cutting edge precision grinding device. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a precision grinding device for CNC lathe tool cutting edges.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A precision grinding device for CNC lathe tool cutting edge includes a grinding wheel disposed above a worktable and multiple sets of clamping assemblies for fixing the lathe tool. The multiple clamping assemblies are located at the same height. The grinding wheel is reciprocated by a moving assembly. The height and tilt angle of the grinding wheel are adjusted by a lifting assembly and a tilting assembly. The moving assembly includes a first guide rail fixedly connected to the upper surface of the worktable and a moving block slidably connected to the surface of the first guide rail.

[0007] In some embodiments, the tilting assembly includes a rotating plate rotatably connected to one side of the lifting column, a drive motor for the grinding wheel is fixedly connected to the upper surface of the rotating plate, and the rotating plate is driven to rotate by a worm gear and a worm.

[0008] In some embodiments, the clamping assembly includes a clamping plate fixedly connected to the upper surface of the fixing block and a rotating head fixedly connected to one side of the fixing block, the rotating head being rotatably connected to the surface of the connecting seat.

[0009] In some embodiments, multiple clamping components adjust their angles simultaneously via a synchronization component. The synchronization component includes a push rod slidably connected to the upper surface of a support plate and multiple insert rods fixedly connected to the side of the push rod. The lower surface of the fixing block is provided with a connecting groove that mates with the insert rods. The connecting groove is an elongated groove.

[0010] In some embodiments, the plurality of cutting tools are oscillating independently via a oscillating assembly, the oscillating assembly including a oscillating frame and a second guide rail fixedly connected to the upper surface of the oscillating frame, the connecting seat being slidably connected to the surface of the second guide rail, and the support plate being vertically slidably connected to the surface of the oscillating frame.

[0011] In some embodiments, the support plate is driven to rise and fall by a jacking assembly, which includes a first inclined block and a second inclined block fixedly connected to the lower surface of the support plate. The first and second inclined blocks each have an inclined surface on their opposite sides.

[0012] In some embodiments, the cutting tool adjusts its tilt angle and position via an adjustment assembly. The adjustment assembly includes a carriage slidably connected to two third guide rail surfaces and guide posts fixedly connected to both ends of a swing frame. The swing frame is rotatably connected to the surface of the carriage, and arc-shaped guide grooves are fixedly connected to both ends of the carriage. The guide posts are slidably connected inside the guide grooves.

[0013] In some embodiments, both third guide rails are fixedly connected to the surface of the worktable, the carriage is driven to move by a fifth threaded rod, and the sliding direction of the carriage is perpendicular to the sliding direction of the moving block.

[0014] In some embodiments, the connecting seat is limited by a limiting component, which includes a fixed frame fixedly connected to one side of the connecting seat and a limiting rod vertically slidably connected to the inner side of the fixed frame. The upper surface of the swing frame is provided with a limiting hole that cooperates with the limiting rod.

[0015] In some embodiments, multiple cutting tools are positioned by a positioning plate. The positioning plate has multiple positioning grooves on its surface. The positioning grooves are contour grooves that match the shape of the cutting tools. Multiple positioning rods are fixedly connected to the lower surface of the positioning plate. A positioning hole is provided at the axis of the rotating head.

[0016] Compared with the prior art, the present invention provides a precision grinding device for CNC lathe tool cutting edge, which has the following beneficial effects.

[0017] 1. This invention, by setting multiple sets of clamping components, can simultaneously clamp multiple cutting tools of the same type. After positioning multiple cutting tools, the grinding wheel is moved to grind multiple cutting tools, thereby achieving the purpose of batch grinding and improving grinding efficiency. By setting tilting components, the tilting angle of the grinding wheel can be adjusted so that the side of the grinding wheel can grind the main flank face of the cutting tool.

[0018] 2. In this invention, by setting a synchronization component, the third threaded rod drives the push rod to slide on the surface of the support plate, and multiple insert rods move synchronously. With the cooperation of the connecting groove, the multiple insert rods push the fixed block to rotate around the rotating head, thereby simultaneously adjusting the angle of multiple cutting tools. After the grinding wheel moves in a straight line, it grinds the front and rear cutting faces of multiple cutting tools at the same time, improving grinding efficiency.

[0019] 3. In this invention, by setting up a push assembly, the push assembly is used to separate the insert rod from the connecting groove, allowing the clamping plate to rotate freely through the rotating head. At the same time, the connecting seat slides on the surface of the second guide rail, bringing the other multiple tools closer together, leaving enough rotation space for the rotation of one of the cutting tools, so that the clamping plate and the cutting tool can be manually rotated, which is convenient for obtuse angle grinding.

[0020] 4. In this invention, by setting a limiting component, when the support plate slides upward to insert the rod into the connecting groove, the top rod pushes the rocker to rotate, causing the other end of the rocker to press the limiting rod, thereby inserting the limiting rod into the limiting hole and automatically limiting the connecting seat, thus achieving synchronous operation.

[0021] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Reference Figure 1-15 A precision grinding device for CNC lathe tool cutting edge includes a grinding wheel 2 set above a worktable 1 and multiple sets of clamping components 3 for fixing the lathe tool. The multiple clamping components 3 are located at the same height. The grinding wheel 2 is driven to rotate by a drive motor. The grinding wheel 2 is reciprocated by a moving component 203. The height and tilt angle of the grinding wheel 2 are adjusted by a lifting component 201 and a tilting component 202. refer to Figure 1-4 The lifting assembly 201 includes a sliding column 2011 and a lifting column 2012 that is vertically slidably connected to the surface of the sliding column 2011. A first threaded rod 2013 is rotatably connected to the top of the lifting column 2012. The first threaded rod 2013 is threadedly connected to the top of the sliding column 2011. A handwheel is fixedly connected to the upper end of the first threaded rod 2013. refer to Figure 3 and Figure 5 The tilting assembly 202 includes a rotating plate 2021 rotatably connected to one side of the lifting column 2012. The drive motor of the grinding wheel 2 is fixedly connected to the upper surface of the rotating plate 2021. The rotating plate 2021 is driven to rotate by a worm wheel 2022 and a worm 2023. The worm wheel 2022 is fixedly connected to the end of the rotating shaft of the rotating plate 2021. The worm 2023 is rotatably connected to the side of the lifting column 2012. The worm 2023 and the worm wheel 2022 mesh with each other. A handwheel is fixedly connected to the upper end of the worm 2023. refer to Figure 2 The moving component 203 includes a first guide rail 2031 fixedly connected to the upper surface of the worktable 1 and a moving block 2032 slidably connected to the surface of the first guide rail 2031. A sliding column 2011 is fixedly connected to the upper surface of the moving block 2032. The moving block 2032 is driven to move by a second threaded rod 2033. The second threaded rod 2033 is rotatably connected to the upper surface of the worktable 1 and threadedly connected to the surface of the moving block 2032. The second threaded rod 2033 is driven to rotate by a drive motor.

[0040] It is understandable that by setting multiple sets of clamping components 3, multiple cutting tools of the same model can be clamped at the same time. After positioning multiple cutting tools, the grinding wheel 2 is moved to grind multiple cutting tools, thereby achieving the purpose of batch grinding and improving grinding efficiency. By setting the lifting component 201, the first threaded rod 2013 is rotated by the handwheel, thereby driving the lifting column 2012 to adjust the height of the grinding wheel 2. By setting the tilting component 202, the rotating plate 2021 is driven to rotate under the action of the worm 2023 and the worm wheel 2022, thereby adjusting the tilt angle of the grinding wheel 2 so that the side of the grinding wheel 2 can grind the main flank face of the cutting tool; by setting the moving component 203, the drive motor drives the second threaded rod 2033 to rotate, thereby driving the moving block 2032 to slide on the surface of the first guide rail 2031, thereby causing the grinding wheel 2 to move back and forth, realizing automatic grinding of the front face and the secondary flank face of the cutting tool.

[0041] For details, please refer to Figure 6-7 The clamping assembly 3 includes a clamping plate 302 fixedly connected to the upper surface of the fixing block 301 and a rotating head 303 fixedly connected to one side of the fixing block 301. The rotating head 303 is rotatably connected to the surface of the connecting seat 304. The surface of the connecting seat 304 is provided with scale lines. The clamping plate 302 clamps the cutting tool with multiple bolts.

[0042] Understandably, by setting up the clamping assembly 3, after the lathe tool is placed in the clamping plate 302, the lathe tool is clamped by multiple bolts. After multiple lathe tools are fixed in the clamping plate 302 respectively, the multiple lathe tools are kept in the same position, and the cutting tip of the lathe tool is positioned on the rotation axis of the rotating head 303. The clamping plate 302 is rotated with the rotating head 303, thereby adjusting the angle of the lathe tool and grinding a suitable angle.

[0043] For details, please refer to Figure 8-12 Multiple clamping components 3 are simultaneously adjusted in angle by a synchronization component 4. The synchronization component 4 includes a push rod 401 slidably connected to the upper surface of the support plate 403 and multiple insert rods 402 fixedly connected to the side of the push rod 401. A connecting groove 4021 that mates with the insert rods 402 is provided on the lower surface of the fixing block 301. The connecting groove 4021 is an elongated groove. The insert rods 402 are inserted into the connecting groove 4021. The push rod 401 is driven to rotate by a third threaded rod 404. The third threaded rod 404 is rotatably connected to the side of the support plate 403 and threadedly connected to the surface of the push rod 401. A handwheel is fixedly connected to the end of the third threaded rod 404.

[0044] Understandably, when it is necessary to adjust the angle of the cutting tool, the third threaded rod 404 is rotated by the handwheel, so that the push rod 401 slides on the upper surface of the support plate 403. The push rod 401 drives multiple insert rods 402 to move synchronously. With the cooperation of the connecting groove 4021, the multiple insert rods 402 push the fixed block 301 to rotate around the rotating head 303, so that the angle of multiple cutting tools can be adjusted synchronously. After the grinding wheel 2 moves in a straight line, it grinds the rake face and secondary flank face of multiple cutting tools at the same time, improving grinding efficiency.

[0045] For details, please refer to Figure 8 , Figure 9 and Figure 12 Multiple cutting tools can swing independently through the swing assembly 5. The swing assembly 5 includes a swing frame 501 and a second guide rail 502 fixedly connected to the upper surface of the swing frame 501. The connecting seat 304 is slidably connected to the surface of the second guide rail 502. The swing frame 501 is Z-shaped. The support plate 403 is vertically slidably connected to the surface of the swing frame 501. Two guide rods 503 are fixedly connected to the upper surface of the swing frame 501. The support plate 403 is vertically slidably connected to the surface of the guide rods 503. The support plate 403 is driven to rise and fall by the push assembly 504. The push assembly 504 includes a first inclined block 5041 and a second inclined block 5042 fixedly connected to the lower surface of the support plate 403. The first inclined block 5041 and the second inclined block 5042 are provided with inclined surfaces on opposite sides. The first inclined block 5041 is threadedly connected to the surface of the fourth threaded rod 5043. The fourth threaded rod 5043 is rotatably connected to the surface of the swing frame 501. A handwheel is fixedly connected to the end of the fourth threaded rod 5043.

[0046] It is understandable that after the lathe tool is ground, the tool tip needs to be obtuse to improve its service life. When obtuse angle is ground, the tool tip needs to be rotated to grind a very small radius. Therefore, the clamping plate 302 needs to rotate around the rotating head 303, and the rotation angle needs to be large. When the distance between the multiple clamping components 3 is small, the rotation angle of the clamping plate 302 will affect each other, making it impossible to grind the obtuse angle smoothly. When the distance between the multiple clamping components 3 is large, the movement distance of the grinding wheel 2 will be too large, which will affect the grinding efficiency. Therefore, a push component 504 is set up to separate the insert rod 402 from the connecting groove 4021, so that the clamping plate 302 can rotate freely through the rotating head 303. At the same time, the connecting seat 304 slides on the surface of the second guide rail 502, bringing the other multiple tools closer together, leaving enough rotation space for the rotation of one of the lathe tools, so that the clamping plate 302 and the lathe tool can be manually rotated for obtuse angle grinding.

[0047] When the limiting position of the fixed block 301 is released, the first inclined block 5041 is slid away from the second inclined block 5042 by the fourth threaded rod 5043. Under the action of gravity, the support plate 403 slides down automatically, causing the insertion rod 402 to separate from the connecting groove 4021. After the obtuse angles of the multiple cutting tools are ground, the positions of the multiple fixed blocks 301 are slid back to their original positions, causing the first inclined block 5041 to push the second inclined block 5042 and the support plate 403 to slide up, pushing the insertion rod 402 into the connecting groove 4021, so that it can drive the fixed block 301 and the clamping plate 302 to rotate again.

[0048] For details, please refer to Figure 1 and Figure 8The cutting tool adjusts its tilt angle and position via the adjustment assembly 6. The adjustment assembly 6 includes a slide 601 slidably connected to the surfaces of the two third guide rails 604 and guide posts 602 fixedly connected to both ends of the swing frame 501. The swing frame 501 is rotatably connected to the surface of the slide 601 and is driven to rotate by a drive motor. Arc-shaped guide grooves 603 are fixedly connected to both ends of the slide 601, and the guide posts 602 are slidably connected inside the guide grooves 603. The guide grooves 603 and the axis of rotation of the swing frame 501 are concentrically arranged. The two third guide rails 604 are fixedly connected to the upper surface of the worktable 1. The slide 601 is driven to move by a fifth threaded rod 605. The fifth threaded rod 605 is threadedly connected to the bottom of the slide 601 and is driven to rotate by a drive motor. The sliding direction of the slide 601 is perpendicular to the sliding direction of the moving block 2032.

[0049] It is understandable that by driving the swing frame 501 to rotate on the surface of the slide 601 through the drive motor, the inclination angle of the cutting tool can be adjusted, and the secondary back face of the cutting tool can be ground. When the swing frame 501 rotates, it rotates in the guide groove 603 through the guide post 602, which improves the stability during rotation; it rotates through the fifth threaded rod 605, which drives the slide 601 to move on the surface of the third guide rail 604, so that the cutting tool is close to the grinding wheel 2 for grinding.

[0050] For details, please refer to Figure 8 and Figure 11-14 The connecting seat 304 is limited by the limiting component 7. The limiting component 7 includes a fixed frame 701 fixedly connected to one side of the connecting seat 304 and a limiting rod 702 vertically slidably connected to the inner side of the fixed frame 701. The upper surface of the swing frame 501 is provided with a limiting hole 7021 that cooperates with the limiting rod 702. The surface of the limiting rod 702 is fitted with a spring 703 that pushes the limiting rod 702 to slide upward. The surface of the fixed frame 701 is rotatably connected with a rocker plate 704 that presses the limiting rod 702. The upper surface of the support plate 403 is fixedly connected with a top rod 705 that pushes the rocker plate 704 to rotate.

[0051] Understandably, to ensure that the synchronization component 4 can drive the fixed block 301 and the clamping plate 302 to rotate stably through the rotating head 303, it is necessary to limit the sliding of the connecting seat 304. Therefore, a limiting component 7 is set so that the limiting rod 702 is inserted into the limiting hole 7021, thereby limiting the connecting seat 304 and preventing it from moving. When the support plate 403 slides upward and inserts the rod 402 into the connecting groove 4021, it drives the top rod 705 to slide upward, thereby pushing the rocker 704 to rotate, so that the other end of the rocker 704 presses the limiting rod 702, thereby limiting the sliding of the connecting seat 304. 02 Insert the rod into the limiting hole 7021 to automatically limit the connection seat 304; when the support plate 403 slides down to separate the rod 402 from the connecting groove 4021, it drives the top rod 705 to separate from the rocker plate 704. Under the action of the spring 703, it pushes the limiting rod 702 to separate from the limiting hole 7021, achieving the purpose of automatic separation; through the above operation, when the rod 402 is connected to the connecting groove 4021, the limiting rod 702 limits the connection seat 304; when the rod 402 is separated from the connecting groove 4021, it releases the limitation on the connection seat 304, achieving synchronous operation.

[0052] For details, please refer to Figure 6-7 and Figure 15 Multiple cutting tools are positioned by a positioning plate 8. The surface of the positioning plate 8 has multiple positioning grooves 801, which are contour grooves that match the shape of the cutting tool. Multiple positioning rods 802 are fixedly connected to the lower surface of the positioning plate 8. A positioning hole 8021 is provided at the axis of the rotating head 303. A groove for avoiding the tool tip is provided at the corner of the positioning groove 801. The positioning rods 802 correspond to the grooves.

[0053] Understandably, a positioning plate 8 is set up to quickly position and install the cutting tool. Before installing the cutting tool, the positioning plate 8 is inserted into the positioning hole 8021 through the positioning rod 802 to position the positioning plate 8. Then, when installing the cutting tool, the main cutting edge and the secondary cutting edge of the cutting tool are aligned with the two positioning surfaces of the positioning groove 801 to achieve rapid positioning of the cutting tool. By setting the groove, even if the wear condition of each cutting tool is different, the groove avoids the cutting tool tip. By using the main cutting edge and the secondary cutting edge for positioning, multiple cutting tools can be positioned, thereby setting the cutting tool tip at the axis of the rotating head 303. The positioning groove 801 of the positioning plate 8 has different models to match different types of cutting tools.

[0054] In this invention, before installing the cutting tool, a positioning plate 8 of the corresponding model is inserted into the positioning hole 8021 via a positioning rod 802 to position the positioning plate 8. When installing the cutting tool, the cutting tool is placed in the clamping plate 302, so that the main cutting edge and the secondary cutting edge of the cutting tool are in contact with the two positioning surfaces of the positioning groove 801, achieving rapid positioning of the cutting tool. Then, the cutting tool is clamped and fixed with bolts. The slide 601 is moved on the surface of the third guide rail 604 by the fifth threaded rod 605, so that the cutting tool is close to the grinding wheel 2 for grinding. When grinding the rake face, the swing frame 501 is rotated on the surface of the slide 601 by the drive motor, adjusting the rake angle of the cutting tool to a state where the cutting edge is lower than the tail of the cutting tool. Then, the second... The threaded rod 2033 drives the moving block 2032 to slide on the surface of the first guide rail 2031, thereby causing the grinding wheel 2 to reciprocate and automatically grind the rake face of the cutting tool. Then, the drive motor drives the swing frame 501 to rotate on the surface of the slide 601, adjusting the inclination angle of the cutting tool to a state where the cutting edge is higher than the tail of the cutting tool. The moving component 203 drives the grinding wheel 2 to reciprocate and grind the secondary flank face of the cutting tool. When grinding the primary flank face of the cutting tool, the worm gear 2023 and worm wheel 2022 drive the rotating plate 2021 to rotate, adjusting the inclination angle of the grinding wheel 2 so that the side angle of the grinding wheel 2 matches the angle of the primary flank face of the cutting tool. The fifth threaded rod 605 drives the slide 601 to rotate. 01 and the cutting tool are close to the side of the grinding wheel 2 to automatically grind the main flank face of the cutting tool. After the initial grinding of the cutting tool is completed, the inclination angle of the grinding wheel 2 is reset. Then, the first inclined block 5041 is slid away from the second inclined block 5042 by the fourth threaded rod 5043. Under the action of gravity, the support plate 403 automatically slides downward, causing the insert rod 402 to separate from the connecting groove 4021. The clamping plate 302 rotates freely through the rotating head 303. At the same time, the push rod 705 separates from the rocker plate 704. Under the action of the spring 703, the limiting rod 702 is pushed to separate from the limiting hole 7021, automatically releasing the limiting of the connecting seat 304. The connecting seat 304 slides on the surface of the second guide rail 502, and the remaining... Multiple cutting tools are brought close together, leaving sufficient space for the rotation of one of the cutting tools. This allows for manual rotation of the clamping plate 302 and the cutting tool for obtuse angle grinding. After all the cutting tools have been ground, the positions of the multiple fixing blocks 301 are slidably reset, causing the first inclined block 5041 to push the second inclined block 5042 and the support plate 403 upwards, pushing the insertion rod 402 into the connecting groove 4021. At the same time, the push rod 705 slides upwards, thereby pushing the rocker plate 704 to rotate. The other end of the rocker plate 704 presses the limiting rod 702, causing the limiting rod 702 to insert into the limiting hole 7021, automatically limiting the connecting seat 304. This allows the fixing blocks 301 and the clamping plate 302 to rotate again.
