Description

Technical Field

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

[0002] Carbide tool grinding equipment is a high-precision machine specifically designed for grinding and repairing carbide tools. This equipment can precisely control the tool's geometric parameters, ensuring high quality and long tool life. Carbide tool grinding equipment is classified in various ways according to tool type and shape, such as external cylindrical grinding machines and internal cylindrical grinding machines, and is widely used in the automotive, aerospace, and other fields. With the development of CNC technology, these machines are constantly improving in automation and precision grinding capabilities, providing a guarantee for improving tool production efficiency and quality.

[0003] Chinese patent CN115502788A discloses a tool edge grinding device, including a worktable with a turntable. Multiple mounting seats are evenly distributed around the outer edge of the turntable's upper surface. A positioning mechanism is provided on one side of each mounting seat. A grinding wheel for grinding the tool edge is located on one side of the turntable. Its advantages are: by incorporating mounting seats for positioning the tool, a pneumatic pressure head for fixing the tool, a guide mechanism for fixing the grinding wheel, and a sensor for detecting the tool's sharpening state, the quality and stability of tool sharpening are no longer limited by the operator's skill level, proficiency, or fatigue. Since the turntable's rotation speed is equal to the grinding wheel's grinding speed, and multiple paired mounting seats and pneumatic pressure rods are evenly distributed on the turntable's outer edge, the grinding wheel can continuously grind the tool edge, thereby significantly improving the production efficiency of tool sharpening.

[0004] As shown in the aforementioned patent, current automated tool grinding technology typically involves controlling the grinding wheel or tool to move along a preset trajectory to a designated grinding starting position, ensuring contact between the tool and the grinding wheel for precise grinding. However, even tools produced in the same batch may exhibit slight differences in overall dimensions. This difference is particularly noticeable when performing restorative grinding on used tools, as wear, damage, or deformation may occur during use, affecting the tool's original dimensions. Furthermore, the grinding wheel itself wears with use, leading to a reduction in diameter and shape changes. This wear on the grinding wheel also causes a deviation between the preset trajectory and the actual grinding trajectory required. Due to these two factors, even if the tool or grinding wheel moves along the preset trajectory, the accuracy during the actual grinding process is difficult to guarantee. This may result in incomplete contact between the tool and the grinding wheel or excessive pressure between them, thus affecting the final cutting accuracy.

[0005] Therefore, it is necessary to provide a high-precision alloy tool grinding equipment to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a high-precision alloy tool grinding equipment that can monitor and adjust the pressure between the grinding wheel and the tool in real time, thereby ensuring that a constant grinding pressure can be maintained even when there are slight differences in tool size or wear of the grinding wheel.

[0030] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Please see Figures 1-3 In this embodiment of the invention, a high-precision alloy tool grinding device includes a grinding table 1. A grinding wheel 2 is rotatably mounted on the top of the grinding table 1, and a motor (not shown in the figure) for driving the grinding wheel 2 to rotate is mounted on the bottom of the grinding table 1. At least one tool clamping and feeding mechanism 3 is mounted on one side of the grinding wheel 2. The tool clamping and feeding mechanism 3 can clamp the tool and drive the tool to move. Multiple tool clamping and feeding mechanisms 3 can be provided and arranged in a circular array outside the grinding wheel 2, so as to grind multiple tools simultaneously. The tool clamping and feeding mechanism 3 includes a support plate 7, a pressure sensor 9, and a clamp 15. The grinding table 1 is provided with a mechanism for driving the support plate 7 toward or away from the grinding wheel 2. The first drive assembly 4 moves away from the grinding wheel 2. An elastic connection assembly 8 is mounted on the support plate 7. A pressure sensor 9 is installed on the movable end of the elastic connection assembly 8. The measuring end of the pressure sensor 9 is mounted on a clamp 15 via an adjustment mechanism. The clamp 15 is used to hold the tool. The adjustment mechanism can adjust the angle of the clamp 15, thereby adjusting the angle of the tool held on the clamp 15 to switch the grinding position. This solution, through the combined use of the pressure sensor 9 and the elastic connection assembly 8, can monitor and adjust the pressure between the grinding wheel 2 and the tool in real time, ensuring constant grinding pressure even with slight differences in tool size or wear on the grinding wheel 2. This is crucial for ensuring grinding accuracy and effectively avoids insufficient grinding or excessive wear caused by uneven pressure.

[0032] In this embodiment, preferably, see [reference] Figure 7 The elastic connection assembly 8 includes a connecting cylinder 81, a connecting column 82, and a third spring 83. The connecting cylinder 81 is fixedly connected to the support plate 7 and passes through the support plate 7. One end of the connecting column 82 is fixedly connected to the pressure sensor 9, and the other end of the connecting column 82 extends into the connecting cylinder 81 and slides with the connecting cylinder 81. One end of the third spring 83 is fixedly connected to one end of the connecting column 82, and the other end of the third spring 83 is fixedly connected to the end wall of the connecting cylinder 81. Through the setting of the third spring 83, the elastic connection between the support plate 7 and the pressure sensor 9 is realized, so that after the tool comes into contact with the grinding wheel 2, as the support plate 7 moves toward the grinding wheel 2, the third spring 83 is gradually compressed. The greater the compression of the third spring 83, the greater the pressure between the grinding wheel 2 and the tool, thereby enabling precise adjustment of the pressure between the grinding wheel 2 and the tool.

[0033] In this embodiment, preferably, see [reference] Figure 8 The first drive assembly 4 includes a first guide rail 41, which is fixedly mounted on the top of the grinding table 1. A first slide block 43 is slidably mounted on the first guide rail 41. A support plate 7 is fixedly mounted on the top of the first slide block 43. A first screw 42 is rotatably mounted inside the first guide rail 41. The first screw 42 passes through the first slide block 43 and is threadedly connected. A first motor 44 is fixedly mounted on one end of the first guide rail 41. The output end of the first motor 44 is fixedly connected to one end of the first screw 42. The first motor 44 can drive the first screw 42 to rotate, thereby driving the first slide block 43 to move along the X-axis, and then driving the support plate 7 to move along the X-axis, so that the tool can move closer to or further away from the grinding wheel 2.

[0034] In this embodiment, preferably, see [reference] Figures 2-4 The adjustment mechanism includes a support cover 10, a connecting frame 12, a support ring 11, a connecting ball 14, and a support column 13. The middle part of the support cover 10 is fixedly connected to the measuring end of the pressure sensor 9. The support ring 11 is fixedly connected to the support cover 10 through the connecting frame 12. The connecting ball 14 is movably installed inside the support ring 11. The center of the connecting ball 14 is located at the same point as the center of the spherical surface on which the support cover 10 is located. One side of the connecting ball 14 is fixedly connected to the clamp 15, and the other side of the connecting ball 14 is fixedly connected to the support column 13. An adjustment mechanism is fitted on the support column 13. An adjustment ring 17 with an angle of 13 is provided. A drive rod 18 is fixedly connected to one side of the adjustment ring 17. A second drive assembly 5 and a third drive assembly 6 are provided on one side of the drive rod 18 to move the drive rod 18 in the vertical plane. A locking assembly for locking the connecting ball 14 is provided on the connecting ball 14. A ball bearing 16 is embedded and installed at the end of the support column 13 away from the support ring 11. The ball bearing 16 contacts the inner wall of the support cover 10. The ball bearing 16 can provide auxiliary support for the support column 13 to reduce the load on the support ring 11 and the connecting frame 12.

[0035] By setting the connecting ball 14, the clamp 15 can move within a certain range, thereby adjusting the angle of the tool and changing the grinding surface of the tool. After adjustment, the surface of the tool to be ground must be parallel to the end face of the measuring end of the pressure sensor 9, so that the pressure value detected by the pressure sensor 9 is the same as the pressure value between the tool and the grinding wheel 2. When adjusting the angle of the clamp 15, the locking component first releases the lock on the connecting ball 14, and then the second drive component 5 and the third drive component 6 drive the drive rod 18 to move the adjusting ring 17, so that the adjusting ring 17 contacts the support column 13, thereby driving the support column 13 to rotate, and then the connecting ball 14 drives the clamp 15 to rotate. After adjustment, the adjusting ring 17 is driven to move so that the adjusting ring 17 does not contact the support column 13, thereby avoiding the adjusting ring 17 affecting the pressure sensor 9's measurement of the pressure between the tool and the grinding wheel 2.

[0036] In this embodiment, preferably, see [reference] Figure 8 The second drive assembly 5 includes a second guide rail 51, which is fixedly mounted on one side of the support plate 7. A second slide block 53 is slidably mounted inside the second guide rail 51. A second screw 52 is rotatably mounted inside the second guide rail 51, passing through the second slide block 53 and threadedly connected. A second motor 54 is fixedly mounted at one end of the second guide rail 51, and the output end of the second motor 54 is fixedly connected to one end of the second screw 52. A connecting rod 55 is fixedly mounted on one side of the second slide block 53. The third drive assembly 6 includes a third guide rail 61, which is fixedly connected to one end of the connecting rod 55. A third slide block 63 is slidably mounted inside the third guide rail 61. One end of the drive rod 18 is connected to the third slide block 63. The third guide rail 61 is fixedly connected to the third guide rail 61, which is rotatably mounted with a third screw 62. The third screw 62 passes through the third slide block 63 and is threadedly connected. A third motor 64 is fixedly mounted at one end of the third guide rail 61, and the output end of the third motor 64 is fixedly connected to one end of the third screw 62. The second guide rail 51 is set along the Z-axis, and the third guide rail 61 is set along the Y-axis. When the second motor 54 rotates, it can drive the second screw 52 to rotate, causing the second slide block 53 to move along the Z-axis. When the third motor 64 rotates, it can drive the third screw 62 to rotate, causing the third slide block 63 to move along the Y-axis, thereby realizing the movement of the drive rod 18 in the vertical plane, and thus allowing the position of the adjusting ring 17 to be arbitrarily adjusted.

[0037] It should be noted that the first motor 44, the second motor 54, the third motor 64 and the pressure sensor 9 are all connected to the control module on the computer. The computer can control the working status of the first motor 44, the second motor 54 and the third motor 64, thereby adjusting the movement and angle adjustment of the clamp 15 according to the preset value. The specific control method is existing technology and will not be described in detail here.

[0038] If the locking component is driven by a circuit or air circuit, the circuit and air circuit connection will affect the pressure sensor 9's measurement of the pressure between the tool and the grinding wheel 2. If it is manually adjusted, the automation level of the device will be reduced, and the convenience of grinding will be reduced. To address this, the following locking component was designed, which can automatically lock and unlock the locking component without affecting the measurement of the pressure value.

[0039] Please see Figures 3-6 In this embodiment of the invention, the locking assembly includes an adjusting post 19, a locking post 23, a second spring 24, and a first spring 21. A sliding groove 20 is formed in the connecting ball 14 and the adjusting post 19. The adjusting post 19 is slidably installed in the sliding groove 20. One end of the adjusting post 19 extends into the connecting ball 14 and is chamfered. Multiple sets of first through grooves 1401 and second through grooves 1402 are formed on the connecting ball 14. The first through groove 1401 and the second through groove 1402 are connected and coaxially arranged. The locking post 23 is slidably installed in the first through groove 1401 and the second through groove 1402. A connecting plate 25 is fixedly installed at one end of the locking post 23. The second spring 24 is sleeved on the locking post 23. One end of the second spring 24 is fixedly connected to the connecting plate 25, and the other end of the second spring 24 is fixedly connected to the inner wall of the second through groove 1402. A rubber pad 27 is embedded inside the support ring 11. When the outer peripheral wall of the adjusting post 19 is in contact with the connecting plate 25, the locking post 23 is locked. When the receiving plate 25 contacts, the end of the locking pin 23 extends into the first through groove 1401 and presses against the rubber pad 27; one end of the adjusting pin 19 is fixedly connected to the first spring 21, and one end of the first spring 21 is fixedly connected to the inner side wall of the slide groove 20. Multiple driving blocks 22 are fixedly installed on the outer peripheral wall of the adjusting pin 19. The multiple driving blocks 22 are arranged in a ring array with the axis of the adjusting pin 19 as the array center. Multiple protruding grooves 1301 are opened on the support pin 13. The number of protruding grooves 1301 is the same as the number of driving blocks 22. The driving blocks 22 pass through the protruding grooves 1301 and can slide in the protruding grooves 1301. The end of the driving block 22 is provided with an inclined surface 2201. Before the adjusting ring 17 moves to contact the support pin 13, the inner ring wall of the adjusting ring 17 contacts the inclined surface 2201 of the driving block 22, thereby pushing the driving block 22 to move away from the connecting ball 14.

[0040] In this embodiment, preferably, a plurality of balls 26 are embedded in the side wall of the adjusting ring 17 away from the connecting ball 14. The arrangement of the balls 26 reduces the resistance during the process of the adjusting ring 17 moving to a position where it does not contact the support column 13 and the drive block 22.

[0041] Working principle: First, the tool is fixed on the fixture 15. Then, the first drive assembly 4 drives the support plate 7 to move toward the grinding wheel 2, thereby moving the tool toward the grinding wheel 2 so that the tool comes into contact with the grinding wheel 2. The tool is then ground by the rotation of the grinding wheel 2. Subsequently, the support plate 7 continues to move toward the grinding wheel 2, causing the third spring 83 to gradually compress. The greater the compression of the third spring 83, the greater the pressure between the grinding wheel 2 and the tool, until the pressure reaches a predetermined value. As grinding proceeds, metal chips are gradually ground off the tool, causing the pressure between the grinding wheel 2 and the tool to decrease. After the pressure sensor 9 detects the decrease in pressure, it can continue to drive the support plate 7 to move to increase the pressure between the grinding wheel 2 and the tool.

[0042] When the tool needs to change its grinding surface, the first drive assembly 4 and the second drive assembly 5 drive the drive rod 18 to move, thereby moving the adjusting ring 17. As the adjusting ring 17 moves until it contacts the support column 13, its inner ring wall contacts the inclined surface 2201 of the drive block 22, pushing the drive block 22 away from the connecting ball 14. This causes the adjusting column 19 to move away from the connecting ball 14, separating it from the locking column 23. Consequently, the locking column 23 moves away from the rubber pad 27, separating it from the rubber pad 27, thus releasing the lock on the connecting ball 14. Subsequently, as the adjusting ring 17 continues to move, the adjusting column 19 pushes the connecting ball 14 to rotate, thereby adjusting the angle of the clamp 15 to change the tool's grinding surface. After the surface is cut and adjusted, the control ring 17 moves to separate it from the drive block 22 and the support column 13, so that the adjustment ring 17 will not interfere with the pressure sensor 9's detection of the pressure between the tool and the grinding wheel 2. After the adjustment ring 17 separates from the drive block 22, under the elastic action of the first spring 21, the adjustment column 19 moves toward the connecting ball 14, and under the action of the chamfered surface at the end of the adjustment column 19, it pushes the locking column 23 toward the rubber pad 27, thereby pressing it into the rubber pad 27 to lock the connecting ball 14. By moving the adjustment ring 17, the locking component can automatically release the lock on the connecting ball 14 without manual operation or power supply. While ensuring the accuracy of pressure detection, the automation level of the device is improved, and the convenience of grinding is significantly improved.
