Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing equipment technology, and in particular to a cutting tool edge grinding machine. Background Technology

[0002] A tool edge grinding machine is a specialized grinding device for grinding the cutting edges of cutting tools. The structure of a typical tool edge grinding machine includes a worktable, a grinding device mounted on the worktable, a transmission belt, and a robotic arm. In operation, the tool is first placed at the beginning of the transmission belt. The belt then transports the tool to a predetermined position. The robotic arm grasps the front of the tool edge, where the grinding device grinds it. After grinding the front edge, the robotic arm flips the tool so that the back edge is ground. Once the back edge is ground, the robotic arm returns the tool to the transmission belt and removes it, thus completing the grinding process on both sides of the tool edge.

[0003] However, existing tool edge grinding machines still have shortcomings. They are equipped with only one grinding unit, meaning that during operation, the cutting edge must first be gripped by a robotic arm and ground on the front of the blade by the grinding disc, then the blade is flipped over and ground on the back of the blade. This results in slow grinding speed and significantly reduced efficiency. Furthermore, existing grinding discs grind the blade edge using their outer surface. Grinding on the outer surface of the disc causes the disc diameter to gradually decrease, leading to a reduction in the width of the blade edge. This means the blade edge width gradually decreases from the root to the tip, resulting in a narrower cutting edge. This affects the aesthetics of the blade edge and hinders subsequent sharpening processes. Poorly sharpened blades will ultimately reduce their cutting performance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tool edge grinding machine with high working efficiency.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a tool edge grinding machine, comprising a worktable, two grinding devices disposed opposite to each other on the worktable, a tool fixing device disposed on the worktable for fixing a tool, a first pushing mechanism for pushing the tool fixing device to move back and forth, and a second pushing mechanism for pushing the tool fixing device to move up and down. The grinding device comprises a first base, a grinding assembly disposed on the first base, a first motor disposed on the first base for driving the grinding assembly to rotate, and a third pushing mechanism disposed on the worktable for pushing the first base to move left and right. The axis of the grinding assembly is parallel to the movement trajectory of the first base. The tool fixing device is located between the two grinding assemblies. The two third pushing mechanisms can respectively push the corresponding first base to move, thereby causing the two grinding assemblies to move closer to each other and further away from each other.

[0006] In the above scheme, during use, the tool is fixed on the tool fixing device. Then, the first motor is turned on to drive the two grinding components to rotate. Simultaneously, the first pushing mechanism pushes the tool fixing device to move the tool forward, while the two third pushing mechanisms push their corresponding first bases to move, causing the two grinding components to move closer to each other until they contact the tool's cutting edge. At this point, the first and second pushing mechanisms push the tool forward and downward slowly along its cutting edge shape, so that the end faces of the two grinding components grind the root to tail of the cutting edge. After the cutting edge grinding is completed, the third pushing mechanism pushes the two grinding components back to their original positions, and the first and second pushing mechanisms push the tool fixing device back to its original position. Finally, the tool is removed from the tool fixing device, thus completing the cutting edge grinding operation. This scheme, by setting two grinding devices opposite each other on the worktable, can grind both sides of the cutting edge simultaneously, thereby significantly improving grinding efficiency. In addition, by setting the axis of the grinding assembly to be parallel to the movement trajectory of the first base, the blade edge will be ground through the end face of the grinding assembly instead of the side face of the grinding assembly when grinding the blade edge. This prevents the diameter of the grinding assembly from shrinking during grinding, thus ensuring that the blade edge width of each blade remains consistent from the root to the tail. This ensures that the blade edge width remains unchanged, facilitating the next sharpening process and improving the aesthetics of the blade edge.

[0007] Furthermore, the aforementioned grinding assembly includes a rotating drum rotatably connected to a first base and a grinding disc fitted onto the outer end of the rotating drum. A first motor is connected to the rotating drum for transmission. During operation, the grinding disc can be installed on the outer end of the rotating drum, and then the first motor is turned on to drive the rotating drum to rotate. The rotation of the rotating drum will drive the grinding disc to rotate simultaneously. This design, by fitting the grinding disc onto the outer end of the rotating drum, allows for quick replacement of the grinding disc when it is damaged.

[0008] Furthermore, the outer end face of the grinding disc is inclined, which makes the shape of the outer end face of the grinding disc more closely fit the shape of the blade edge, making it easier to grind the blade edge.

[0009] Furthermore, the aforementioned third pushing mechanism includes a second base mounted on the workbench and a pushing component mounted on the second base. The lower part of the first base and the upper part of the second base are slidably engaged, and the pushing component can push the first base to slide left and right relative to the second base.

[0010] Furthermore, the aforementioned pushing assembly includes a second motor located on the outside of the second base and a lead screw connected to the second motor. A connecting ring is provided under the first base, and the connecting ring is threadedly driven to the lead screw. When the second motor drives the lead screw to rotate, the lead screw will drive the connecting ring of the first base to move left and right along the lead screw, thereby pushing the first base to slide left and right relative to the second base.

[0011] Furthermore, the second base is provided with two guide rails, and the first base is provided with guide grooves at the corresponding guide rail positions. The two guide rails slide in cooperation with the corresponding guide grooves, so that the first base can slide along the guide rails of the second base through its guide grooves. This makes the sliding of the first base smoother and more stable.

[0012] Furthermore, a boss is provided on the worktable corresponding to the position below the second base. The second base is located on the boss and can rotate horizontally relative to the boss. In this way, the grinding disc can be rotated by rotating the second base, and the angle of rotation of the grinding disc can be adjusted to adjust the grinding width of the blade edge.

[0013] Furthermore, the aforementioned boss is provided with a rotating shaft, and the second base is provided with a rotating groove. The rotating shaft of the boss and the rotating groove of the second base are rotatably engaged, thereby enabling the second base to rotate around the rotating shaft of the boss and ensuring the rotational stability of the second base.

[0014] Furthermore, the aforementioned boss sidewall is provided with a scale, through which the rotation angle of the second base can be calculated, thus allowing for more precise adjustment of the rotation angle of the grinding disc.

[0015] Furthermore, the aforementioned tool edge grinding machine also includes a control device for operating the first and second pushing mechanisms. The control device is electrically connected to the first and second motors to achieve automated operation of the tool edge grinding machine and save labor costs.

[0016] This utility model's blade grinding machine uses two grinding discs to simultaneously grind both sides of the blade, significantly improving grinding efficiency. Grinding the blade surface via the end faces of the grinding discs ensures that the disc diameter does not decrease during grinding, maintaining a consistent blade width from root to tip for each blade. This guarantees a stable blade width, facilitating subsequent sharpening processes and improving the aesthetics of the blade surface. Furthermore, after grinding the blade surface via the disc end faces, the second base of the grinding machine is rotatable. Rotating the second base causes the grinding discs to rotate, allowing adjustment of the grinding width of the blade surface by changing the disc angle. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment provides a tool edge grinding machine, including a worktable 1, two grinding devices disposed opposite to each other on the worktable 1, a tool fixing device 2 disposed on the worktable 1 for fixing a tool, a first pushing mechanism for pushing the tool fixing device 2 to move back and forth, and a second pushing mechanism for pushing the tool fixing device 2 to move up and down. The grinding device includes a first base 31, a grinding assembly 32 disposed on the first base 31, a first motor 33 disposed on the first base 31 for driving the grinding assembly 32 to rotate, and a third pushing mechanism disposed on the worktable 1 for pushing the first base 31 to move left and right. The axis of the grinding assembly 32 is parallel to the movement trajectory of the first base 31. The tool fixing device 2 is located between the two grinding assemblies 32. The two third pushing mechanisms can respectively push the corresponding first base 31 to move, thereby causing the two grinding assemblies 32 to move closer to each other and further away from each other.

[0028] like Figure 2-4 As shown, as an improved embodiment, the grinding assembly 32 includes a rotating cylinder 321 rotatably connected to a first base 31 and a grinding disc 322 fitted onto the outer end of the rotating cylinder 321. The axes of the grinding disc 322 and the rotating cylinder 321 are parallel to the movement trajectory of the first base 31. The outer end face of the grinding disc 322 is flush with the outer end face of the rotating cylinder 321. A first motor 33 is connected to the rotating cylinder 321 for transmission. During operation, the grinding disc 322 can be installed on the outer end of the rotating cylinder 321, and then the first motor 33 can be turned on to drive the rotating cylinder 321 to rotate. The rotation of the rotating cylinder 321 will drive the grinding disc 322 to rotate. This solution, by fitting the grinding disc 322 onto the outer end of the rotating cylinder 321, allows for quick replacement of the grinding disc 322 when it is damaged.

[0029] In addition, the outer end face of the grinding disc 322 is set as an inclined surface 3221 so that the shape of the outer end face of the grinding disc 322 can better fit the shape of the blade edge, making it easier to grind the blade edge.

[0030] This embodiment of the tool edge grinding machine uses two grinding devices arranged opposite each other on the worktable 1, so that the front and back sides of the blade 62 can be ground simultaneously by the two grinding discs 322, thereby greatly improving the grinding efficiency. Furthermore, the axes of the grinding discs 322 and the rotating cylinder 321 are set parallel to the moving trajectory of the first base 31, so that the two third pushing mechanisms respectively push the corresponding first base 31 to move, causing the outer end faces of the two grinding discs 322 to move closer and further apart. Thus, when grinding the blade edge, the blade edge is ground through the end faces of the two grinding discs 322, rather than through the sides of the two grinding discs 322. This prevents the diameter of the two grinding discs 322 from decreasing during grinding. Figure 5 , 6 As shown, this allows each tool 6 to be ground until the width b of the blade 621 from the root to the tail remains consistent, thus ensuring that the width of the blade 62 remains unchanged. This facilitates the next sharpening process of the tool 6 and also improves the aesthetics of the blade 621.

[0031] Example 2

[0032] This embodiment is a further improvement on the structure of the tool edge grinding machine in Embodiment 1. The improvement is as follows: Figure 1-3 As shown, the third pushing mechanism includes a second base 51 disposed on the workbench 1 and a pushing component disposed on the second base 51. The lower part of the first base 31 is slidably engaged with the upper part of the second base 51, and the pushing component can push the first base 31 to slide left and right relative to the second base 51.

[0033] Specifically, the aforementioned pushing assembly includes a second motor 521 located on the outside of the second base 51 and a lead screw 522 connected to the second motor 521. A connecting ring 311 is provided under the first base 31, and the connecting ring 311 is threadedly connected to the lead screw 522. When the second motor 521 drives the lead screw to rotate, the lead screw 522 drives the connecting ring 311 of the first base 31 to move left and right along the lead screw 522, thereby pushing the first base 31 to slide left and right relative to the second base 51. Furthermore, two guide rails 511 are arranged opposite each other on the second base 51, and guide grooves are provided under the first base 31 corresponding to the positions of the guide rails 511. The two guide rails 511 slide in cooperation with their respective guide grooves, allowing the first base 31 to slide along the guide rails 511 of the second base 51 through its guide grooves. This makes the sliding of the first base 31 smoother and provides better sliding stability.

[0034] The principle of the third pushing mechanism in this embodiment is as follows: when the two second motors 521 are activated to drive the two lead screws 522 to rotate in the forward direction, the two lead screws 522 will respectively transmit power to the connecting rings 311 of the two first bases 31 to move towards each other along the lead screws 522. At the same time, the movement of the two first bases 31 will drive the two grinding discs 322 to move towards each other. When the two second motors 521 drive the two lead screws 522 to rotate in the reverse direction, they can push the two grinding discs 322 to move away from each other. Thus, the two third pushing mechanisms can respectively push the corresponding first bases 31 to move, thereby causing the outer end faces of the two grinding discs 322 to move closer and further apart.

[0035] Example 3

[0036] This embodiment is a further improvement on the structure of the tool edge grinding machine in Embodiment 2. The improvement lies in, for example... Figure 1-3 As shown, a boss 11 is provided on the workbench 1 corresponding to the position below the second base 51. The second base 51 is located on the boss 11 and can rotate horizontally relative to the boss 11. Specifically, a rotating shaft 111 is provided on the boss 11, and a rotating groove 510 is provided below the second base 51. The rotating shaft 111 of the boss 11 and the rotating groove 510 of the second base 51 are rotatably engaged, thereby enabling the second base 51 to rotate around the rotating shaft 111 of the boss 11, ensuring the rotational stability of the second base 51.

[0037] In this embodiment, the tool edge grinding machine has a rotatable second base 51. During use, rotating the second base 51 causes the grinding disc 322 to rotate as well. This rotation of the grinding disc 322 changes the grinding width of the blade edge 621, allowing adjustment of the grinding width b on the blade edge 621. Specifically, a larger rotation angle of the grinding disc 322 results in a smaller grinding width b on the blade edge 621, while a smaller rotation angle results in a larger grinding width b.

[0038] In addition, the side wall of the aforementioned boss 11 is provided with a scale 112, through which the rotation angle of the second base 51 can be calculated, thus allowing for more precise adjustment of the rotation angle of the grinding disc 322.

[0039] As an improvement to this embodiment, such as Figure 1 As shown, the aforementioned tool edge grinding machine also includes a control device 4 for operating the first and second pushing mechanisms. The control device 4 is electrically connected to the first motor 33 and the second motor 521 to achieve automated operation of the tool edge grinding machine and save labor costs.

[0040] Specifically, the workbench 1 is provided with several parallel sliding rods 13. The tool fixing device 2 is slidably connected to the sliding rods 13 via a sliding seat 7, which can slide back and forth along the sliding rods 13. The first pushing mechanism includes a first cylinder and a first push rod that can extend and retract relative to the first cylinder. The front end of the first push rod is connected to the rear side of the sliding seat 7. The control device 4 is electrically connected to the first cylinder. By driving the first push rod to extend and retract through the first cylinder, the sliding seat 7 can be driven to slide back and forth relative to the sliding rods 13. As the sliding seat 7 moves, it will drive the tool fixing device 2 to move, thereby realizing the structural function of the first pushing mechanism to drive the tool fixing device 2 to move back and forth.

[0041] In addition, the second pushing mechanism mentioned above includes a second cylinder mounted on the slide 7 and a second push rod that can extend and retract relative to the second cylinder. The upper end of the second push rod is connected to the tool fixing device 2, and the control device 4 is electrically connected to the second cylinder. By driving the second push rod to extend and retract through the second cylinder, the tool fixing device 2 can be moved up and down, thereby realizing the structural function of the second pushing mechanism to drive the tool fixing device 2 to move up and down.

[0042] When using the tool edge grinding machine of this utility model, first fix the tool 6 on the tool fixing device 2, then turn on the control device 4. The control device 4 controls the first cylinder to drive the first push rod to extend and push the slide block 7 to slide forward, so that the tool 6 on the tool fixing device 2 moves forward to the position between the two grinding discs 322. Then, the control device 4 controls the two first motors 33 to drive the corresponding rotating drums 321 to rotate, so that the two grinding discs 322 rotate. At the same time, the control device 4 controls the two second motors 521 to drive the corresponding lead screws 522 to rotate in the forward direction, so that the two grinding discs 322 move in the direction of moving closer to each other, so that the two grinding discs 322 move to the position between the two grinding discs 322. When the end face of 22 contacts the cutting surface 621 of the blade 62, the control device 4 will then operate the first cylinder and the second cylinder to push the blade 6 to move slowly forward and downward along the shape of its cutting surface 621, so that the end faces of the two grinding discs 322 grind the root to the tail of the cutting surface 621. After the cutting surface grinding is completed, the second motor 521 is operated to push the two grinding discs 322 to reset in a direction away from each other. At the same time, the first cylinder and the second cylinder are operated to push the tool fixing device 2 to move backward and upward to reset. Finally, the tool 6 is removed from the tool fixing device 2, thereby completing the grinding operation of the cutting surface 621 of the tool 6.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
