Description

Technical Field

[0001] This invention relates to the field of peripheral grinding technology, and in particular to a device and method for synchronous chamfering grinding of dual CBN inserts for peripheral grinding machines. Background Technology

[0002] CBN composite inserts, with their high hardness, high wear resistance, good impact resistance, and high temperature resistance, have become the core cutting tools for precision machining of high-hardness steel, alloy steel, and other materials. Chamfering grinding is a key process in the production and processing of CBN inserts, and its processing quality directly affects the performance and service life of the inserts. Peripheral grinding machines, due to their high processing accuracy, stable cutting performance, and low thermal deformation and wear, have become the main processing equipment for chamfering grinding of CBN inserts. They can achieve high-precision chamfering of inserts by continuously grinding the inserts through the rotation of the grinding wheel.

[0003] Currently, existing peripheral grinding machines use a single-insert-per-step processing mode when chamfering CBN inserts, meaning only one CBN insert can be chamfered at a time. This processing mode has significant technical drawbacks: Firstly, the utilization rate of the grinding wheel and various drive and adjustment components is extremely low in this single-process mode, the grinding machine's processing efficiency cannot be fully utilized, single-process processing is time-consuming, and processing efficiency is low, making it difficult to meet the processing needs of mass production of CBN inserts. Secondly, the insert fixing and adjustment devices of existing grinding machines are designed for single-insert processing, lacking corresponding synchronous transmission and dual-position adjustment structures, making it impossible to achieve synchronous grinding of multiple inserts. They can only be clamped and adjusted one by one, further increasing processing time and production costs. Therefore, there is an urgent need to develop a device and method that can achieve synchronous chamfering grinding of two CBN inserts, solving the problems of low processing efficiency and low equipment utilization caused by the existing single-process mode, and adapting to the mass production needs of CBN inserts. Summary of the Invention

[0005] The technical solution adopted by this invention to solve its technical problem is: a dual CBN insert synchronous chamfering grinding device for a peripheral grinding machine, comprising: A grinding wheel device includes a grinding wheel and a grinding wheel drive device, wherein the grinding wheel is mounted on the grinding wheel drive device; An adjustable blade fixing device is provided on one side of the grinding wheel assembly. The adjustable blade fixing device includes a first CBN blade adjusting mechanism and a second CBN blade adjusting mechanism. The first CBN blade adjusting mechanism includes a base, a rotating platform mounted on the base, and a blade clamping device mounted on the rotating platform for fixing the first CBN blade. An external gear ring is fixed to the outer periphery of the rotating platform. The second CBN blade adjusting mechanism includes a lifting platform, a drive body, a transmission gearbox, and a blade placement frame for fixing the second CBN blade. The lifting platform is located on one side of the base. The drive body and the transmission gearbox are both mounted on the lifting platform. The blade placement frame is connected to the transmission gearbox. The transmission gearbox is provided with a bevel gear, which is arranged horizontally and meshes with the external gear ring. While the rotating platform drives the blade clamping device and the first CBN blade to rotate, it can also drive the blade placement frame and the second CBN blade to rotate through the external gear ring and the bevel gear. The transmission gearbox can be driven by the drive body to slide on the lifting platform to separate the bevel gear from the external gear ring.

[0006] As a further improvement of the present invention, the axis of the grinding wheel is distributed in the horizontal direction, the first CBN blade is arranged vertically and located inside the grinding wheel, and the second CBN blade is arranged in the horizontal direction and located outside the grinding wheel.

[0007] As a further improvement of the present invention, when the rotating platform simultaneously drives the first CBN blade and the second CBN blade to rotate, the rotation center axis of the first CBN blade is perpendicular to the rotation center axis of the second CBN blade.

[0008] As a further improvement of the present invention, a rotary motor is installed in the middle of the base along the vertical direction, and the rotary platform is rotatably installed on the base and fixedly connected to the output shaft of the rotary motor.

[0009] As a further improvement of the present invention, the blade clamping device includes a housing, a telescopic chuck mounted on the housing in a horizontal direction, and a drive motor connected to the telescopic chuck. The drive motor is used to drive the telescopic chuck to rotate the first CBN blade.

[0010] As a further improvement of the present invention, the transmission gearbox includes a housing that is slidably mounted on the lifting platform and an internal gear ring and a gear set that are rotatably mounted in the housing. The internal gear ring is connected to the bevel gear through the gear set, and the blade holder is fixedly connected to the internal gear ring through a connecting rod.

[0011] As a further improvement of the present invention, the gear set includes a transition gear and a differential gear both disposed inside the internal gear ring, the transition gear meshing between the differential gear and the bevel gear, and the differential gear meshing with the internal gear ring.

[0012] As a further improvement of the present invention, the driving body includes a telescopic driving device and a servo motor, the telescopic driving device being driven and connected to the transmission gearbox; a transmission rod is fixedly connected to the output end of the servo motor, a gear shaft is provided on the side of the transition gear facing the driving body, and a insertion slot is provided on the gear shaft, the insertion slot being directly opposite the transmission rod and being sized to match.

[0013] As a further improvement of the present invention, both the blade clamping device and the transmission gearbox are equipped with cameras for capturing the chamfering grinding process of the grinding wheel on the first CBN blade and the second CBN blade.

[0014] This invention also provides a method for simultaneous chamfering grinding of dual CBN inserts for peripheral grinding machines, employing the dual CBN insert simultaneous chamfering grinding apparatus for peripheral grinding machines as described above, and comprising the following steps: The first CBN blade is fixed to the blade clamping device, and the second CBN blade is fixed to the blade placement rack; The height of the transmission gearbox is adjusted by the lifting platform, and then the drive body drives the transmission gearbox to slide horizontally on the lifting platform, so that the bevel gear of the transmission gearbox meshes with the outer tooth ring on the outer periphery of the rotating platform to complete the synchronous transmission. Start the grinding wheel drive device to drive the grinding wheel to rotate; according to the chamfering grinding requirements, drive the blade clamping device and the first CBN blade to rotate a certain angle through the rotating platform to grind and chamfer the first CBN blade; while the rotating platform rotates, drive the blade placement frame and the second CBN blade to rotate through the meshing transmission of the external gear ring and the bevel gear to grind and chamfer the second CBN blade. If the first CBN blade or the second CBN blade needs to be chamfered and ground separately, the drive body drives the transmission gearbox to slide on the lifting platform to separate the bevel gear from the external gear ring, and the drive body can directly drive the transmission gearbox to rotate and adjust the blade holder.

[0015] The beneficial effects of this invention are as follows: This invention provides a synchronous chamfering grinding device and method for dual CBN inserts on a peripheral grinding machine. By setting a grinding wheel device in conjunction with an adjustable insert fixing device containing a first CBN insert adjustment mechanism and a second CBN insert adjustment mechanism, and relying on the transmission method in which the outer toothed ring on the outer periphery of the rotating platform meshes with the bevel gear of the transmission gearbox, the rotating platform drives the first CBN insert to rotate synchronously, thereby achieving synchronous chamfering grinding of dual CBN inserts. This significantly improves the processing efficiency of CBN insert chamfering grinding. At the same time, the transmission gearbox can separate the bevel gear from the outer toothed ring under the drive of the drive body, enabling the device to achieve independent chamfering grinding of a single CBN insert. This effectively increases the flexibility of the device. The overall structure is reasonably laid out, and the connection and cooperation of each component are adapted to the conventional processing conditions of the peripheral grinding machine. The meshing transmission structure design also ensures the transmission accuracy of the synchronous rotation of dual CBN inserts, ensuring the processing quality of dual CBN inserts.

[0022] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0023] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0024] See Figures 1 to 6 The present invention provides a dual CBN insert synchronous chamfering grinding device for a peripheral grinding machine, including a grinding wheel device and an adjustable insert fixing device disposed on one side of the grinding wheel device. The grinding wheel device includes a grinding wheel 1 and a grinding wheel drive device 2. The grinding wheel 1 is mounted on the grinding wheel drive device 2, and the grinding wheel drive device 2 is used to rotate the grinding wheel 1 at high speed to perform synchronous chamfering grinding on the first CBN insert 5 and the second CBN insert 12.

[0025] Furthermore, the adjustable blade fixing device includes a first CBN blade adjustment mechanism and a second CBN blade adjustment mechanism.

[0026] The first CBN blade adjustment mechanism includes a base 3, a rotating platform 4 horizontally mounted on the base 3, and a blade clamping device 6 mounted on the rotating platform 4 for fixing the first CBN blade 5. The rotating platform 4 can be used to drive the blade clamping device 6 and the first CBN blade 5 to rotate. In addition, an external toothed ring 41 is fixed to the outer periphery of the rotating platform 4.

[0027] Furthermore, the second CBN blade adjustment mechanism includes a lifting platform 7, a drive body 8, a transmission gearbox 9, and a blade holder 10 for fixing the second CBN blade 12. The lifting platform 7 is located on the left side of the base 3. The drive body 8 and the transmission gearbox 9 are both mounted on the lifting platform 7. The transmission gearbox 9 is located on the side of the drive body 8 facing the first CBN blade adjustment mechanism, and the transmission gearbox 9 can slide left and right relative to the drive body 8 on the lifting platform 7 to move closer to or away from the rotating platform 4.

[0028] Furthermore, the blade holder 10 is distributed horizontally and connected to the transmission gearbox 9. The transmission gearbox 9 is provided with a bevel gear 91, which is arranged horizontally and meshes with the external gear ring 41. While the rotating platform 4 drives the blade clamping device 6 and the first CBN blade 5 to rotate, it can also drive the blade holder 10 and the second CBN blade 12 to rotate through the external gear ring 41 and the bevel gear 91. Then, the high-speed rotating grinding wheel 1 simultaneously performs chamfering grinding on the first CBN blade 5 and the second CBN blade 12.

[0029] It is worth mentioning that the transmission gearbox 9 can be driven by the drive body 8 to slide on the lifting platform 7 so that the bevel gear 91 is separated from the external gear ring 41. In this way, the independent chamfering grinding of the first CBN blade 5 and the second CBN blade 12 can be achieved.

[0030] This invention, by setting up a grinding wheel device in conjunction with an adjustable blade fixing device containing a first CBN blade adjustment mechanism and a second CBN blade adjustment mechanism, and relying on the transmission method of the outer toothed ring 41 on the outer periphery of the rotating platform 4 meshing with the bevel gear 91 of the transmission gearbox 9, achieves synchronous chamfering grinding of the two CBN blades when the rotating platform 4 drives the first CBN blade 5 to rotate, thereby significantly improving the processing efficiency of CBN blade chamfering grinding. At the same time, the transmission gearbox 9 can separate the bevel gear 91 from the outer toothed ring 41 under the drive of the drive body 8, enabling the device to achieve independent chamfering grinding of a single CBN blade, effectively increasing the flexibility of the device. The overall structure layout is reasonable, and the connection and cooperation of each component are adapted to the conventional processing conditions of the peripheral grinding machine. The meshing transmission structure design also ensures the transmission accuracy of the synchronous rotation of the two CBN blades, ensuring the processing quality of the two CBN blades.

[0031] like Figure 1 and Figure 2 As shown, the axis of the grinding wheel 1 is distributed horizontally, the first CBN insert 5 is vertically positioned and located inside the grinding wheel 1, and the second CBN insert 12 is horizontally positioned and located outside the grinding wheel 1, with the second CBN insert 12 positioned diagonally below the first CBN insert 5. This invention, by configuring the axial direction of the grinding wheel 1 and the installation orientation of the first CBN insert 5 and the second CBN insert 12 relative to the grinding wheel 1, ensures that the vertically positioned first CBN insert 5 and the horizontally positioned second CBN insert 12 precisely correspond to the inner and outer grinding surfaces of the grinding wheel 1, respectively. This fully utilizes the effective grinding area of ​​the grinding wheel 1, improving its grinding utilization rate. Simultaneously, the differentiated vertical and horizontal installation methods of the CBN inserts adapt to the chamfering grinding requirements of different parts and directions of the CBN inserts, ensuring the processing effect and dimensional accuracy of the CBN insert chamfering grinding.

[0032] During the rotation of the rotary platform 4, the blade clamping device 6 and the first CBN blade 5 are driven to rotate. Simultaneously, the external gear ring 41 and the bevel gear 91 drive the blade placement frame 10 and the second CBN blade 12 to rotate as well. The first CBN blade 5 rotates around a vertical rotation axis, while the second CBN blade 12 rotates around a horizontal rotation axis. That is, the rotation axis of the first CBN blade 5 is perpendicular to the rotation axis of the second CBN blade 12. This technical solution enables the first CBN blade 5 and the second CBN blade 12 to form mutually perpendicular rotary grinding trajectories during synchronous grinding, accurately adapting to the chamfering requirements of different angles and working surfaces of the CBN blades. At the same time, the vertical rotation axis design matches the grinding direction of the grinding wheel 1, utilizing the effective grinding area of ​​the grinding wheel 1.

[0033] See Figure 3 and Figure 6 A rotary motor 11 is installed vertically in the middle of the base 3. The rotating platform 4 is rotatably mounted on the base 3 and fixedly connected to the output shaft of the rotary motor 11, providing a stable and precise rotational driving force for the rotating platform 4.

[0034] See Figure 4 The blade clamping device 6 includes a housing 61 fixed to the top of the rotating platform 4, a telescopic chuck 62 mounted horizontally on the housing 61, and a drive motor 63 connected to the telescopic chuck 62. The telescopic chuck 62 can extend and retract to securely clamp the first CBN blades 5 distributed vertically. It should be noted that the telescopic chuck 62 in this blade clamping device 6 is a conventional telescopic chuck structure for blade clamping in the prior art. Its specific telescopic transmission principle, internal structure design, and control method all adopt mature technologies known in the art, and will not be elaborated on here. The telescopic chuck 62 can realize conventional telescopic movement and can adapt and adjust the telescopic stroke according to the specifications and dimensions of the first CBN blades 5 distributed vertically to complete the stable clamping and fixing of the first CBN blades 5, meeting the requirements of the blade clamping device 6 for the fixing strength and positional accuracy of the blade clamping.

[0035] Furthermore, the drive motor 63 is used to drive the telescopic chuck 62 to rotate the first CBN blade 5, which can flexibly adjust the grinding angle of the first CBN blade 5 according to the chamfering grinding requirements, or perform grinding processing on the periphery of the first CBN blade 5.

[0036] Continue reading Figure 4 The transmission gearbox 9 includes a housing 92, an internal gear ring 93, and a gear set. The housing 92 is slidably mounted on the lifting platform 7 via a linear guide rail. The internal gear ring 93 and the gear set are rotatably mounted inside the housing 92. The internal gear ring 93 is confined within the housing 92 and can only move circumferentially. The rotatable engagement structure between the internal gear ring 93 and the housing 92 is a conventional technique in this field, and the attached diagram is only a simplified structural illustration. A bevel gear 91 is rotatably mounted inside the housing 92 via a mounting bracket, and the bevel teeth of the bevel gear 91 extend outward through the right side plate of the housing 92. The internal gear ring 93 is connected to the bevel gear 91 via the gear set. The blade holder 10 is fixedly connected to the internal gear ring 93 via a connecting rod 13.

[0037] Specifically, the gear set includes a transition gear 94 and a differential gear 95, both located inside the internal gear ring 93. A gear shaft 941 is integrally mounted on the transition gear 94, allowing it to be rotatably mounted within the housing 92 via the gear shaft 941. A rotating shaft is integrally mounted on the differential gear 95, allowing it to be rotatably mounted within the housing 92 via the rotating shaft. A gear section is also provided on the bevel gear 91. The transition gear 94 meshes between the gear sections of the differential gear 95 and the bevel gear 91, while the differential gear 95 meshes with the internal gear ring 93. This achieves reliable power transmission between the rotary platform 4 and the second CBN cutting tool 12, effectively improving the stability of synchronous grinding of the second CBN cutting tool 12.

[0038] In this invention, the drive body 8 is fixed to the top of the lifting platform 7, and a telescopic drive device is provided inside it. The telescopic drive device is connected to the transmission gearbox 9. The telescopic drive device can be an electric push rod, etc., which is used to drive the transmission gearbox 9 to slide on the lifting platform 7 so that the bevel gear 91 is separated from the external gear ring 41, realizing a smooth and rapid switching between the two modes of synchronous grinding and independent grinding.

[0039] In addition, a servo motor is installed inside the drive body 8. A transmission rod is fixedly connected to the output end of the servo motor. A slot 942 is provided on the end of the gear shaft 941 facing the drive body 8. The slot 942 is a polygonal multi-faceted slot. The slot 942 and the transmission rod are directly opposite each other and are matched in size.

[0040] When the second CBN insert 12 needs to be independently chamfered and ground, the transmission rod at the output end of the servo motor is engaged with the insertion slot 942 on the gear shaft 941 of the transition gear 94, so that the servo motor can achieve precise power connection with the transition gear 94, thereby directly driving the transition gear 94 to rotate, realizing precise adjustment of the grinding angle of the second CBN insert 12, and meeting the processing requirements of different angles of the insert when the device grinds independently.

[0041] It should be noted that the lifting platform 7 used in this invention is an existing conventional lifting structure. Its specific lifting drive method, structure, etc. all follow the mature conventional technical solutions in this field. This invention does not improve the structure of the lifting platform itself. Conventional electric lifting platform products in this field can be directly selected. It can stably and accurately realize the overall height adjustment and positioning of itself and the components mounted above it, and meet the height adjustment requirements of this device in the grinding operation.

[0042] In addition, both the blade clamping device 6 and the transmission gearbox 9 are equipped with cameras 14 for filming the chamfering grinding process of the grinding wheel 1 on the first CBN blade 5 and the second CBN blade 12. By filming and recording the chamfering grinding process of the grinding wheel 1 on the first CBN blade 5 and the second CBN blade 12, the operator can monitor the grinding status in real time, analyze the grinding effect, and then make precise adjustments and optimizations to the grinding process to ensure that the quality and precision of the chamfering grinding of the double CBN blades meet the expected standards.

[0043] This invention also provides a method for simultaneous chamfering grinding of dual CBN inserts for a peripheral grinding machine, employing the aforementioned simultaneous chamfering grinding apparatus for dual CBN inserts for a peripheral grinding machine, and comprising the following steps: The first CBN blade 5 is fixed to the telescopic chuck 62 of the blade clamping device 6, and the second CBN blade 12 is placed on the blade holder 10 by insertion and removal. The height of the transmission gearbox 9 is adjusted by the lifting platform 7, and then the drive body 8 drives the transmission gearbox 9 to slide horizontally on the lifting platform 7, so that the bevel gear 91 of the transmission gearbox 9 meshes with the outer tooth ring 41 on the outer periphery of the rotating platform 4, and completes the synchronous transmission. The grinding wheel drive device 2 is started to drive the grinding wheel 1 to rotate; according to the chamfering grinding requirements, the blade clamping device 6 and the first CBN blade 5 are driven to rotate at a certain angle through the rotating platform 4 to grind and chamfer the first CBN blade 5; while the rotating platform 4 rotates, the external gear ring 41 and the bevel gear 91 mesh to drive the blade placement frame 10 and the second CBN blade 12 to rotate to grind and chamfer the second CBN blade 12.

[0044] If chamfering grinding is required for either the first CBN blade 5 or the second CBN blade 12, the drive body 8 drives the transmission gearbox 9 to slide on the lifting platform 7 to separate the bevel gear 91 from the external gear ring 41. The drive body 8 can directly drive the transmission gearbox 9 to rotate and adjust the blade holder 10 and the second CBN blade 12. At the same time, the height of the second CBN blade 12 can be adjusted via the lifting platform 7.

[0045] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
