Description

Technical Field

[0001] This invention relates to the field of precision machining, specifically to a boring tool grinding device. Background Technology

[0002] The cutting tool is the core working component in the mechanical boring process. The accuracy of the cutting surface and the sharpness of the cutting edge of the boring tool directly determine the machining accuracy and the quality of the finished product. Depending on the machining hole diameter, the material being machined, and the machining conditions, boring tools are available in various specifications and models. In order to meet different boring mechanical properties and chip removal requirements, the tool body is equipped with chip removal grooves, inclined cutting edges, and arc transition edge structures.

[0003] In the production and subsequent reuse and repair of boring tools, grinding is typically used to finish the cutting edge, edge, and transition structure of the tool to ensure its cutting performance. Currently, traditional tool grinding equipment has a relatively simple structure. On the one hand, it is difficult to adaptively adjust to boring tools of different sizes and groove structures, making it incompatible with grinding operations for multiple types of boring tools. On the other hand, the traditional grinding structure has limited adjustment freedom, making it difficult to perform fine grinding on irregularly shaped positions such as inclined cutting edges and arc transition edges of boring tools. This results in poor grinding uniformity and a high risk of cutting edge defects and angular deviations, failing to meet the grinding production requirements of high-precision boring tools.

[0004] In view of the above-mentioned technical problems, it is necessary to propose a boring tool grinding device to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a boring tool grinding device for grinding boring tools of different specifications and sizes, different groove structures, and with inclined cutting edges and arc transition cutting edges.

[0006] The present invention provides a boring tool grinding device, including a support base plate, a support disk rotatably disposed on the support base plate, and an optical probe disposed on the side of the support disk. The device is characterized in that it further includes a lifting support assembly, a synchronous adjustment assembly, a telescopic transmission mechanism, and multiple grinding devices located above the support disk. The lifting support assembly is used to drive the synchronous adjustment assembly and the grinding device to rise and fall. The synchronous adjustment assembly includes a synchronous main gear, multiple synchronous auxiliary gears distributed circumferentially along and meshing with the synchronous main gear, and an adjustment mechanism corresponding to the synchronous auxiliary gears. The adjustment mechanism is used to drive the corresponding grinding device to move radially along the support plate, so that the multiple grinding devices are kept in concentric adjustment. The telescopic transmission mechanism is driven by a drive motor and connected to the grinding device. The grinding device includes a grinding cylinder for conforming to the cutting edge or arc transition surface of the boring tool and a deflection control mechanism for adjusting the deflection angle of the grinding cylinder.

[0007] The beneficial effects of this invention are: (1) The present invention, through the cooperation of the support plate, optical probe, synchronization device and adjustment mechanism, can synchronously adjust the position of multiple grinding devices according to the outer diameter, groove profile and cutting edge position of the boring tool, so that the multiple grinding devices are always located in a concentric circle with the center of the support plate as the center, thereby adapting to the grinding processing requirements of boring tools of different specifications and sizes, and solving the problem that traditional grinding devices are difficult to be compatible with multiple types of boring tools.

[0008] (2) This invention enables the synchronous operation of each adjustment mechanism through the meshing transmission between the synchronous main gear and multiple synchronous sub-gears, thereby allowing each grinding device to form a relatively uniform circumferential grinding force on the boring tool. This structure can reduce the risk of excessive force on one side or in a localized area, and allows the boring tool to maintain a relatively stable central position during the grinding process, which is beneficial to improving the uniformity of the cutting edge grinding and reducing cutting edge defects, angle deviations and localized over-grinding.

[0009] (3) The present invention adjusts the vertical position of the grinding device by means of a hydraulic cylinder and adjusts the radial position of the grinding device by means of an adjustment mechanism, so that the device can simultaneously adapt to the height difference and outer diameter difference of the boring tool, thereby expanding the applicability of the device to boring tools of different specifications and reducing the need for frequent replacement of special fixtures or special grinding parts due to changing tool specifications.

[0013] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0014] like Figures 1 to 7 As shown, this invention provides a boring tool grinding device for grinding boring tools of different specifications, sizes, groove structures, and those with inclined cutting edges or arc transition surfaces. The boring tool grinding device includes a support base plate 1, with legs fixedly installed at the four corners of the lower end of the support base plate 1. A support disk 11 is rotatably connected to the middle of the support base plate 1, and the support disk 11 supports the boring tool to be ground. An optical probe 12 is fixedly connected to the support base plate 1 at the edge of the support disk 11. The optical probe 12 detects the placement of the boring tool on the support disk 11 and can be used to identify the outer diameter, cutting edge position, chip groove contour, or arc transition surface position of the boring tool, thereby providing a reference for the subsequent position adjustment and grinding positioning of the grinding device 8.

[0015] A lifting support rod 13 is fixedly installed at the front end of the edge of the support plate 11. A lifting arm 14 extending towards the center of the support plate 11 is fixedly installed at the upper end of the lifting support rod 13. A hydraulic cylinder 15 extending towards the center of the support plate 11 is fixedly installed at the lower end of the lifting arm 14. A lifting plate 16 is fixedly installed at the lower end of the hydraulic cylinder 15. A motor mounting plate 2 is fixedly installed at the lower end of the lifting plate 16. A drive motor 3 is fixedly installed at the center of the upper end of the motor mounting plate 2. A drive device mounting plate 4 is fixedly connected to the lower end of the motor mounting plate 2. A telescopic transmission mechanism 5 is provided at the upper end of the drive device mounting plate 4. The drive shaft of the drive motor 3 passes through the motor mounting plate 2 and is used to drive the telescopic transmission mechanism 5. A synchronization device mounting plate 6 is fixedly connected to the lower end of the drive device mounting plate 4. A synchronization device 7 is provided at the upper end of the synchronization device mounting plate 6.

[0016] In the above embodiment, the hydraulic cylinder 15 can drive the motor mounting plate 2, the drive device mounting plate 4, the synchronization device mounting plate 6, and the grinding device 8 installed below the synchronization device mounting plate 6 to lift and lower as a whole through the lifting plate 16, thereby adapting to boring tools of different heights and different clamping states. Compared with the traditional fixed grinding structure, this structure can adjust the grinding position according to the actual placement height of the boring tool, reducing the risk of insufficient grinding of the cutting edge or local over-grinding caused by height mismatch.

[0017] The synchronization device 7 includes a main synchronization gear 71, a secondary synchronization gear 72, and an adjustment mechanism 73. The main synchronization gear 71 is rotatably connected to the center of the upper end of the synchronization device mounting plate 6. Multiple secondary synchronization gears 72 are meshed on the edge of the main synchronization gear 71. The multiple secondary synchronization gears 72 are distributed around the circumference of the main synchronization gear 71 and are rotatably connected to the synchronization device mounting plate 6 respectively. An adjustment mechanism 73 is installed between the secondary synchronization gears 72 and the synchronization device mounting plate 6. A grinding device 8 is suspended at the lower end of the adjustment mechanism 73. The grinding device 8 is driven by a telescopic transmission mechanism 5.

[0018] In the above embodiment, multiple synchronous gears 72 are arranged circumferentially around the synchronous main gear 71. When one of the adjustment mechanisms 73 is activated, the corresponding synchronous gear 72 can drive the synchronous main gear 71 to rotate. The synchronous main gear 71 further drives the remaining synchronous gears 72 to rotate synchronously, so that multiple adjustment mechanisms 73 can operate synchronously. As a result, multiple grinding devices 8 can simultaneously approach or move away from the center of the support plate 11 radially, so that multiple grinding devices 8 are always kept in a concentric position with the center of the support plate 11 as the center. This structure can be synchronously adjusted according to the outer diameter of the boring tool, and is suitable for grinding boring tools of different specifications. It can also make the boring tool receive a relatively uniform grinding force in the circumferential direction, reducing uneven grinding, shaking and deviation of the cutting edge angle.

[0019] like Figure 1 , Figure 5 and Figure 6 As shown, the adjustment mechanism 73 includes an adjustment pulley 731, an adjustment belt 732, an adjustment slider 733, a compensating spring rod 734, a mounting slider 735, and an adjustment screw 736. An adjustment groove 61, extending radially along the main synchronous gear 71, is provided on the mounting plate 6 of the synchronization device corresponding to the synchronization gear 72. The adjustment slider 733 and the mounting slider 735 are slidably connected in the adjustment groove 61. A compensating spring rod 734 is fixedly connected between the adjustment slider 733 and the mounting slider 735. The upper end of the synchronization gear 72 is coaxially fixed... An adjusting pulley 731 is fixedly connected to the synchronous device mounting plate 6, which is located at the other end of the adjusting slide 61 and is also rotatably connected to the adjusting pulley 731. The two adjusting pulleys 731 are connected by an adjusting belt 732. One side of the adjusting belt 732 is fixedly connected to the adjusting slider 733. One of the adjusting sliders 733 is connected to an adjusting screw 736 along the radial thread of the synchronous main gear 71. The adjusting screw 736 is rotatably mounted on the upper end of the synchronous device mounting plate 6. A grinding device 8 is suspended at the lower end of the mounting slider 735.

[0020] In the above embodiment, when the adjusting screw 736 is rotated, the adjusting slider 733, which is threadedly connected to the adjusting screw 736, moves along the adjusting groove 61. The adjusting slider 733 pushes the mounting slider 735 to move through the compensating spring rod 734, thereby driving the grinding device 8 to adjust radially along the support plate 11. When the adjusting slider 733 moves, it drives the adjusting belt 732 to move. The adjusting belt 732 drives the corresponding synchronous gear 72 to rotate through the adjusting pulley 731. The synchronous gear 72 drives the other synchronous gears 72 to rotate synchronously through the synchronous main gear 71, so that the grinding devices 8 in the other adjustment mechanisms 73 move radially synchronously. In this way, multiple grinding devices 8 can be adjusted synchronously according to the outer diameter of the boring tool, avoiding the center deviation caused by the independent adjustment of a single grinding device 8.

[0021] In the above embodiment, the compensation spring rod 734 is disposed between the adjusting slider 733 and the mounting slider 735. When the grinding device 8 contacts the cutting edge, groove edge or arc transition surface of the boring tool, the compensation spring rod 734 can provide radial elastic compensation, so that the grinding device 8 can adapt to the small contour changes of the boring tool surface while maintaining the grinding pressure. This structure can reduce the risk of cutting edge chipping or local over-grinding of the cutting edge caused by rigid contact, and is beneficial to improving the uniformity of the grinding of the boring tool cutting edge.

[0022] like Figure 5 and Figure 6As shown, the grinding device 8 includes a grinding mounting base 81, a grinding cylinder 82, a support rod 83, a universal transmission mechanism 84, and a deflection control mechanism 85. The grinding mounting base 81 is L-shaped, with the horizontal section of the grinding mounting base 81 located at the top. A transmission rod 86 is rotatably connected to the horizontal section of the grinding mounting base 81. The transmission rod 86 rotatably passes through the mounting slider 735 and is connected to the telescopic transmission mechanism 5. The lower ends of the grinding mounting base 81 are fixedly connected to the support rods 83 extending towards the axis of the support plate 11. A support ring 87 is rotatably connected between the two support rods 83. The grinding cylinder 82 is rotatably connected to the middle of the support ring 87. A deflection control mechanism 85 for controlling the deflection of the grinding cylinder 82 is provided between the upper and lower sides of the grinding cylinder 82 and the support rod 83. The transmission rod 86 and the grinding cylinder 82 are driven by the universal transmission mechanism 84. The upper end of the grinding mounting base 81 is fixedly connected to the mounting slider 735.

[0023] In the above embodiment, the telescopic transmission mechanism 5 drives the transmission rod 86 to rotate, and the transmission rod 86 drives the grinding cylinder 82 to rotate through the universal transmission mechanism 84. The grinding cylinder 82 is used to grind the cutting surface, edge of the cutting edge, or arc transition edge of the boring tool. Since the boring tool usually has an inclined cutting surface, chip groove and arc transition edge structure, the grinding cylinder 82 can be deflected relative to the support rod 83 under the action of the deflection control mechanism 85 during the grinding process, so that the grinding cylinder 82 can fit the cutting surface or arc transition surface with different inclination angles. Thus, the grinding cylinder 82 no longer grinds in a single vertical posture, but can make adaptive contact according to the contour changes of the irregular surface of the boring tool, thereby improving the problem of uneven grinding of the arc transition position and large deviation of the inclined cutting surface angle in traditional grinding devices.

[0024] like Figure 5 and Figure 6 As shown, the universal transmission mechanism 84 includes a universal joint 841 and a telescopic rod 842. The transmission rod 86 is fixedly connected to a universal joint 841 on each of the grinding cylinder 82. The two universal joints 841 are connected by the telescopic rod 842. The telescopic rod 842 is composed of two straight rods that slide against each other. The two straight rods are fixedly connected to the two universal joints 841 respectively.

[0025] In the above embodiment, when the grinding cylinder 82 deflects at an angle with the arc transition surface or the inclined cutting edge, the two universal joints 841 can adapt to the change in the included angle between the transmission rod 86 and the grinding cylinder 82, and the telescopic rod 842 can adapt to the change in the distance between the two, so that the transmission rod 86 can still stably transmit power when the grinding cylinder 82 is deflected. This structure ensures the continuity of transmission when the grinding cylinder 82 is performing contact grinding, and avoids transmission jamming or power interruption caused by the change in the angle of the grinding cylinder 82.

[0026] like Figure 5As shown, the deflection control mechanism 85 includes a deflection control ring 851, a control spring rod 852, a linkage rod 853, and a force rod 854. Each mounting rod 83 has a horizontal deflection control groove 831 symmetrically opened at its upper and lower ends opposite to the other mounting rod 83. A force rod 854 is slidably connected in each of the upper and lower deflection control grooves 831. A control spring rod 852 is fixedly connected between the force rod 854 and the grinding mounting base 81. A deflection control ring 851 is rotatably connected to each of the upper and lower ends of the grinding cylinder 82. A linkage rod 853 is provided between the deflection control ring 851 and the force rod 854. The two ends of the linkage rod 853 are hinged to the deflection control ring 851 and the force rod 854, respectively.

[0027] In the above embodiment, when the grinding cylinder 82 contacts the arc transition cutting edge or inclined cutting edge of the boring tool, the grinding cylinder 82 deflects under the action of the contact reaction force. When the grinding cylinder 82 deflects, it drives the linkage rod 853 to move through the deflection control ring 851. The linkage rod 853 further drives the force rod 854 to slide along the deflection control groove 831, so that the control spring rod 852 on one side is compressed and the control spring rod 852 on the other side is extended accordingly. Through the elastic balance of the control spring rods 852 on the upper and lower sides, the grinding cylinder 82 can maintain a stable grinding pressure while adhering to the arc transition surface, and return to the initial state after leaving the arc transition surface or stopping the force. This structure is beneficial to reduce the phenomenon of missed grinding, skipping grinding and local over-grinding at the arc transition cutting edge, and improve the grinding quality of irregular cutting edge.

[0028] like Figure 5 and Figure 6 As shown, the upper and lower ends of the grinding cylinder 82 are provided with insertion grooves 821, and a grinding block 822 is inserted into the insertion grooves 821. The upper and lower ends of the grinding cylinder 82 are rotatably connected with locking rings 823. The locking rings 823 are fixedly connected to the grinding block 822 with locking rods 824. The side of the locking rod 824 that is in contact with the grinding block 822 is made of rubber.

[0029] In the above embodiment, the grinding block 822, as a grinding component that directly contacts the cutting surface of the boring tool, can be selected with different grit sizes or different materials according to the material of the boring tool, the surface roughness requirements, or the grinding precision requirements. When the grinding block 822 is worn, the locking ring 823 can be rotated to release the pressing effect of the locking rod 824 on the grinding block 822, and then the grinding block 822 can be taken out from the insertion slot 821 and replaced. The contact surface of the locking rod 824 is made of rubber, which can increase the friction between the locking rod 824 and the grinding block 822, and reduce the risk of the grinding block 822 loosening or falling out during the grinding process. This structure is easy to maintain and replace, which helps to reduce long-term use costs.

[0030] like Figure 1 and Figure 7As shown, a top-pressing fixing rod 9 is rotatably connected to the lower center of the synchronous device mounting plate 6. A vertical sliding groove 91 is provided in the center of the top-pressing fixing rod 9. A top-pressing telescopic rod 92 is slidably connected in the vertical sliding groove 91. A top-pressing spring 93 is fixedly connected between the upper end surface of the top-pressing telescopic rod 92 and the bottom surface of the vertical sliding groove 91.

[0031] In the above embodiment, when the hydraulic cylinder 15 drives the synchronous device mounting plate 6 to descend, the top pressure telescopic rod 92 first contacts the upper end or clamping end of the boring tool to be ground. The top pressure spring 93 applies downward elastic pressure to the top pressure telescopic rod 92, so that the boring tool to be ground is stably attached to the support plate 11. Since the top pressure fixing rod 9 is rotatably connected to the synchronous device mounting plate 6, when the boring tool to be ground rotates with the support plate 11, the top pressure fixing rod 9 can adapt to its rotation state, thereby reducing interference to the rotary grinding process while maintaining axial clamping. This structure is beneficial to improving the clamping stability of the boring tool during the grinding process and reducing uneven grinding of the cutting surface caused by tool offset.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the telescopic transmission mechanism 5 includes a main transmission gear 51, a driven transmission gear 52, a transmission slider 53, and a belt transmission mechanism 54. The main transmission gear 51 is rotatably connected to the middle position of the drive device mounting plate 4, and the main transmission gear 51 is fixedly connected to the output shaft of the drive motor 3. The edge of the main transmission gear 51 meshes with the driven transmission gear 52. The drive device mounting plate 4 has a transmission groove 41 corresponding to the position of the adjustment groove 61. The transmission slider 53 is slidably connected to the mounting slider 735 in the transmission groove 41. The driven transmission gear 52 is evenly distributed around the main transmission gear 51. The transmission rod 86 rotates through the mounting slider 735 and the transmission slider 53. The driven transmission gear 52 drives the transmission rod 86 to rotate through the belt transmission mechanism 54.

[0033] In the above embodiment, the output shaft of the drive motor 3 drives the main transmission gear 51 to rotate, and the main transmission gear 51 drives multiple driven transmission gears 52 to rotate synchronously. The multiple driven transmission gears 52 drive the corresponding transmission rods 86 to rotate through the corresponding belt transmission mechanism 54. Since the transmission slider 53 can move radially in the transmission groove 41 with the mounting slider 735, the transmission rod 86 can still cooperate with the transmission slider 53 when the grinding device 8 is radially adjusted, so that the grinding device 8 can obtain stable power at different radial positions. This structure, in conjunction with the synchronization device 7, enables the device to take into account both radial dimension adaptation and grinding power transmission.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the belt drive mechanism 54 includes a drive pulley 541, a drive belt 542, a tension spring 543, a spring guide rod 544, and a tension slider 545. A drive pulley 541 is coaxially and fixedly connected to the driven gear 52. A drive pulley 541 is located on each side of the drive groove 41, one near the drive gear 51 and the other away from the drive gear 51. A tension slider 545 is rotatably connected to the lower end of one of the drive pulleys 541 away from the drive gear 51. The tension slider 545 slides along the spring guide rod 544. The spring guide rod 544 is mounted on the drive device mounting plate 4, and a tension spring 543 is sleeved on the spring guide rod 544. The two ends of the tension spring 543 are fixedly installed at the fixed connection points between the tension slider 545 and the spring guide rod 544 and the drive device mounting plate 4, respectively. A drive pulley 541 is fixedly connected to the upper end of the drive rod 86. The drive belt 542 transmits the rotation of the driven gear 52 to the drive rod 86. In the above embodiment, the transmission drive gear 52 drives the transmission pulley 541, which is fixed coaxially with it, to rotate. The transmission pulley 541 drives the other transmission pulleys 541 in conjunction with the transmission belt 542, thereby driving the transmission rod 86 to rotate. When the mounting slider 735 drives the transmission rod 86 to move radially, the transmission slider 53 moves synchronously along the transmission groove 41, and the envelope path of the transmission belt 542 changes accordingly. At this time, the tension spring 543 continuously applies an elastic force to the tension slider 545, and the tension slider 545 drives the corresponding transmission pulley 541 to tension the transmission belt 542, so that the transmission belt 542 maintains reliable contact with the transmission pulley 541 during the radial adjustment of the grinding device 8. This structure can reduce belt slack, slippage and speed fluctuation, and improve the rotational stability of the grinding cylinder 82.

[0035] In use, the radial positions of multiple grinding devices 8 are first adjusted by adjusting mechanism 73 according to the outer diameter, cutting edge position, and arc transition surface position of the boring tool to be ground. After the optical probe 12 detects that the boring tool to be ground is placed on the support plate 11, the hydraulic cylinder 15 drives the lifting plate 16 and the grinding assembly below it to descend, so that the top pressure telescopic rod 92 elastically presses the boring tool to be ground and brings the grinding cylinder 82 close to the grinding area. Then, the drive motor 3 drives the grinding cylinder 82 to rotate through the telescopic transmission mechanism 5, the transmission rod 86 and the universal transmission mechanism 84. The support plate 11 drives the boring tool to be ground to rotate relative to the grinding cylinder 82, so that the grinding cylinder 82 grinds the cutting edge, cutting edge and arc transition edge of the boring tool.

[0036] During the grinding process, the synchronous main gear 71, synchronous auxiliary gear 72, and adjustment mechanism 73 work together to ensure that multiple grinding devices 8 are always concentrically adjusted, resulting in more uniform circumferential force on the boring tool. The compensation spring rod 734 provides radial elastic compensation for the grinding device 8, which can adapt to subtle changes in the tool's cutting edge and groove profile. The deflection control mechanism 85 enables the grinding cylinder 82 to deflect at an angle when it contacts the inclined cutting edge or the arc transition edge, and maintains stable contact pressure under the action of the control spring rod 852. The universal transmission mechanism 84 maintains power transmission when the grinding cylinder 82 deflects, and the belt drive mechanism 54 keeps the transmission belt 542 taut when the grinding device 8 moves radially. Thus, the present invention can perform adaptive grinding on boring tools of different specifications and can improve the grinding uniformity, grinding accuracy, and processing stability of inclined cutting edges and arc transition edges.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
