Description

Technical Field

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

[0002] A toothed cutter, also known as a serrated cutter, has teeth on its cutting edge. Generally, the teeth of a toothed cutter need to be processed using a tooth-cutting machine.

[0003] The existing tool threading machine includes a worktable, a grinding wheel with teeth rotatably connected to the worktable, a motor for driving the grinding wheel, a blade fixing mechanism movably connected to the worktable for fixing the blade, and a water spraying device located on the worktable above the grinding wheel. In use, the blade to be threaded is first fixed to the blade fixing mechanism. Then, the motor is turned on to drive the grinding wheel to rotate, and the water spraying device is activated simultaneously. The blade fixing mechanism is then pushed to bring the blade into contact with the grinding wheel, whereby the grinding teeth on the grinding wheel grind the blade to perform the threading process. After the threading is complete, the blade fixing mechanism is pushed to detach the blade from the grinding wheel. Finally, the blade is removed from the blade fixing mechanism, thus completing the blade threading operation.

[0004] However, existing cutting tool threading machines still have shortcomings. They use grinding wheels to grind and thread the cutting tools. After long-term grinding, the grinding teeth on the surface of the grinding wheel will inevitably wear down, causing the grinding wheel to no longer meet the requirements for threading the cutting tools. At this time, a new grinding wheel must be replaced to continue the threading operation. However, the grinding wheel replacement operation is troublesome and reduces work efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tool tooth-opening machine that can directly repair the grinding teeth on the surface of the grinding wheel.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a cutting tool threading machine, including a worktable, a grinding wheel rotatably connected to the worktable, a first motor for driving the grinding wheel to rotate, a blade fixing mechanism movably connected to the worktable for fixing the blade, and a repair wheel rotatably connected to the worktable and located behind the grinding wheel, and a pushing mechanism for pushing the repair wheel to move back and forth. The blade fixing mechanism is located in front of the grinding wheel. Multiple threading teeth are arranged axially on the side of the grinding wheel. The grinding teeth are annular and extend along the circumference of the grinding wheel. Multiple repair teeth for repairing the grinding teeth are arranged axially on the side of the repair wheel. The repair teeth are annular and extend along the circumference of the repair wheel.

[0007] In the above scheme, when using it, first fix the blade to be opened on the blade fixing mechanism, then turn on the first motor to drive the grinding wheel to rotate, and then operate the blade fixing mechanism to move the blade to the position where it is against the grinding wheel. Thus, the grinding teeth on the surface of the grinding wheel grind the blade to open the teeth. After the teeth are opened, operate the blade fixing mechanism to move the blade to the position where it is detached from the grinding wheel. Finally, remove the blade from the blade fixing mechanism to complete the teeth opening operation of the blade. When the grinding wheel wears down after prolonged grinding, making it unable to meet the requirements for cutting the blades, a pushing mechanism moves a repair wheel forward to a position where it abuts the grinding wheel. Simultaneously, the repair teeth of the repair wheel are misaligned with the grinding wheels' teeth. Then, the first motor drives the grinding wheel to rotate, and the pushing mechanism also feeds the repair wheel. This allows the repair teeth on the repair wheel to rotate and grind against the grinding wheels, repairing the grinding wheel's surface. Once the grinding wheel's surface is repaired, the pushing mechanism moves the repair wheel backward, detaching it from the grinding wheel. The repaired grinding wheel then meets the requirements for cutting the blades and can be used again. This eliminates the need to replace the grinding wheel when it wears down; the repair wheel directly repairs the grinding wheels, simplifying the repair process, saving on grinding wheel replacement, improving work efficiency, and allowing the worn grinding wheel to be recycled, saving grinding wheel costs and benefiting the environment.

[0008] Furthermore, the aforementioned pushing mechanism includes a first slide block that is slidably mounted on the worktable, and a pushing component for pushing the first slide block to slide back and forth. The front end of the first slide block is provided with connecting lugs on opposite sides, and a first rotating shaft is rotatably connected between the two connecting lugs. The repair wheel is fitted on the outside of the first rotating shaft. When the pushing component pushes the first slide block to slide back and forth, it will drive the repair wheel to move along with it, thereby realizing the structural function of the pushing mechanism to push the repair wheel to move back and forth.

[0009] Furthermore, the aforementioned pushing component includes a second motor and a first lead screw connected to the second motor. A first connecting block is provided under the first slide block. The first lead screw and the first connecting block are threadedly connected. In use, turning on the second motor can drive the first lead screw to rotate. The rotation of the first lead screw will drive the first connecting block to move back and forth along the first lead screw. While the first connecting block moves, it will drive the first slide block to move, thereby realizing the structural function of the pushing component to push the first slide block to slide back and forth.

[0010] Furthermore, the shaft of the second motor is connected to a drive gear, and the rear end of the first lead screw is connected to a driven gear. The drive gear is connected to the driven gear via a toothed belt, which improves the transmission stability of the first lead screw. In use, when the second motor is turned on, it drives the drive gear to rotate, and the rotation of the drive gear drives the first lead screw to rotate via the toothed belt.

[0011] Furthermore, a second slide block is slidably mounted on the worktable. The second slide block can slide left and right relative to the worktable. The first slide block is slidably fitted onto the second slide block and can slide back and forth relative to the second slide block. A fixed plate is provided on the rear side of the second slide block, and the second motor and the first lead screw are connected to the fixed plate. In use, pushing the second slide block to slide left and right will cause the first slide block and the repair wheel to move accordingly, thus adjusting the left and right position of the repair wheel.

[0012] Furthermore, a second connecting block is provided below the second slide block, and a second lead screw is rotatably connected to the worktable. A turntable is connected to the outer end of the second lead screw, and the second lead screw and the second connecting block are threadedly connected. In use, the second lead screw can be rotated by operating the turntable, and the rotation of the second lead screw will cause the second connecting block to move left and right along the second lead screw. The movement of the second connecting block will drive the second slide block to move. It is equivalent to driving the second slide block to move left and right by rotating the turntable, making operation more convenient.

[0013] Furthermore, a water spraying device and a water-retaining cover are installed on the workbench above the grinding wheel. The water spraying device is located inside the water-retaining cover. During use, when the grinding wheel is grinding the blades, activating the water spraying device will spray water onto the grinding wheel and blades to cool them and reduce dust. The water-retaining cover prevents the water sprayed by the water spraying device from splashing everywhere. The workbench is equipped with a drain outlet so that the water sprayed by the water spraying device can be drained through the drain outlet for recycling.

[0014] Furthermore, the aforementioned water spraying device is a water pipe inserted inside a water-blocking cover. The water pipe has an inlet for connecting to a water source, and multiple water outlets are provided on the side wall of the water pipe. A switch is located near the inlet of the water pipe. In use, the inlet is connected to the water source, and then the switch is turned on. Water will flow into the water pipe and spray out from the water outlets, thus spraying water on the grinding wheel and blades.

[0015] Furthermore, the aforementioned blade fixing mechanism includes a base plate rotatably connected to the worktable. A lower stop and two side stops are provided on the side of the base plate opposite to the grinding wheel. A slot is formed on the upper side of the lower stop, and the two side stops are located on the left and right sides of the lower stop, respectively. In use, the blade is inserted into the slot between the corresponding two side stops. At this time, the two side stops abut against both ends of the blade, thus completing the blade fixing operation. The lower stop and the base plate prevent the blade from moving downwards and forwards, while the two side stops prevent the blade from moving left and right, thereby accurately fixing the blade in place. Pulling the blade upwards allows it to be removed, making disassembly and assembly convenient.

[0016] Furthermore, the aforementioned cutting tool threading machine also includes a control device. The first motor and the second motor are electrically connected to the control device, which controls the operation of the first motor and the second motor, making operation more convenient.

[0017] The tool teeth cutting machine of this utility model does not require the replacement of the grinding wheel when it is worn. Instead, the grinding wheel can be directly repaired on the surface of the grinding wheel through the repair wheel. The repair operation is convenient, saves the process of replacing the grinding wheel, improves work efficiency, and allows the worn grinding wheel to be recycled, saving grinding wheel costs and benefiting the environment.

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0029] Example 1

[0030] like Figure 5 As shown, this embodiment provides a tool teething machine for machining the teeth of a toothed cutter. It includes a worktable 1, a grinding wheel 11 rotatably connected to the worktable 1, a first motor 2 for driving the grinding wheel 11 to rotate, and a blade fixing mechanism movably connected to the worktable 1 for fixing the blade. Two supports 13 are arranged opposite each other on the worktable 1, and a second rotating shaft 131 is rotatably connected between the two supports 13. The first motor 2 is fixed to the outer side of the left support 13, and the rotating shaft of the first motor 2 is connected to the second rotating shaft 131. The grinding wheel 11 is fitted onto the outer side of the second rotating shaft 131. Turning on the first motor 2 will drive the grinding wheel 11 to rotate via the second rotating shaft 131.

[0031] like Figure 1 , 2As shown, the aforementioned cutting tool opening machine also includes a repair wheel 12 rotatably connected to the worktable 1 and located behind the grinding wheel 11, and a pushing mechanism for pushing the repair wheel 12 to move back and forth. The blade fixing mechanism is located in front of the grinding wheel 11. Multiple opening grinding teeth 111 are arranged axially on the side of the grinding wheel 11. The grinding teeth 111 are annular and extend along the circumference of the grinding wheel 11. Multiple repair teeth 121 for repairing the grinding teeth 111 are arranged axially on the side of the repair wheel 12. The repair teeth 121 are annular and extend along the circumference of the repair wheel 12. The rotation center axis of the repair wheel 12 is parallel to the rotation center axis of the grinding wheel 11.

[0032] Specifically, the aforementioned pushing mechanism includes a first slide block 41 slidably mounted on the worktable 1, and a pushing component for pushing the first slide block 41 to slide. The first slide block 41 can slide back and forth relative to the worktable 1. The front end of the first slide block 41 is provided with connecting lugs 411 on opposite sides, and a first rotating shaft 412 is rotatably connected between the two connecting lugs 411. The repair wheel 12 is fitted onto the outside of the first rotating shaft 412. When the pushing component pushes the first slide block 41 to slide back and forth, it will drive the repair wheel 12 to move accordingly, thereby realizing the structural function of the pushing mechanism to push the repair wheel 12 to move back and forth.

[0033] When using the cutting tool thread opener in this embodiment, such as Figure 3 , 4 As shown, first fix the blade 80 to be opened onto the blade fixing mechanism, and then turn on the first motor 2 to drive the grinding wheel 11 to rotate, and then... Figure 5 As shown, the blade fixing mechanism is then operated to move the blade 80 to a position where it abuts against the grinding wheel 11. The grinding teeth 111 on the surface of the grinding wheel 11 grind the blade 80 to perform the tooth opening process. After the tooth opening process is completed, the blade fixing mechanism is operated again to move the blade 80 to a position where it is detached from the grinding wheel 11. Finally, the blade 80 is removed from the blade fixing mechanism, thus completing the tooth opening process of the blade 80.

[0034] When the grinding teeth 111 on the surface of the grinding wheel 11 become worn after long-term grinding and can no longer meet the requirements for the opening of the blade 80, the first slide 41 is pushed by the pushing component to move the repair wheel 12 forward to a position against the grinding wheel 11. At the same time, the repair teeth 121 of the repair wheel 12 are misaligned with the grinding teeth 111 of the grinding wheel 11. Then, the first motor 2 is turned on to drive the grinding wheel 11 to rotate, and the pushing mechanism also drives the repair wheel 12 to feed. Thus, the repair teeth 121 on the surface of the repair wheel 12 and the grinding teeth 111 on the surface of the grinding wheel 11 rotate and grind each other to repair the grinding teeth 111 on the surface of the grinding wheel 11. After the grinding teeth 111 on the surface of the grinding wheel 11 are repaired, the first slide 41 can be pushed by the pushing component to move the repair wheel 12 backward and disengage from the grinding wheel 11. The repaired grinding wheel 11 can then meet the requirements for the opening of the blade 80 and can continue to be used for the opening of the blade.

[0035] In this embodiment, the grinding wheel 11 of the tool cutting machine does not need to be replaced after it is worn. Instead, the grinding teeth 111 on the surface of the grinding wheel 11 can be repaired directly by the repair wheel 12. The repair operation is convenient, saves the replacement process of the grinding wheel 11, improves work efficiency, and enables the worn grinding wheel 11 to be recycled, saving the cost of the grinding wheel 11 and benefiting the environment.

[0036] Example 2

[0037] This embodiment is a further improvement on the structure of the cutting tool threading machine in Embodiment 1. The improvement is as follows: Figure 1 , 2 As shown in Figures 6 and 7, the aforementioned pushing assembly includes a second motor 42 and a first lead screw 43 connected to the second motor 42. A first connecting block 413 is provided below the first slide block 41, and the first lead screw 43 is threadedly connected to the first connecting block 413. The shaft of the second motor 42 is connected to a drive gear 421, and the rear end of the first lead screw 43 is connected to a driven gear 431. The drive gear 421 is connected to the driven gear 431 via a toothed belt 44, which improves the transmission stability of the first lead screw 43. In use, when the second motor 42 is turned on, it drives the drive gear 421 to rotate. The rotation of the drive gear 421 drives the driven gear 431 to rotate via the toothed belt 44. The rotation of the first lead screw 43 then drives the first connecting block 413 to move back and forth along the first lead screw 43. The movement of the first connecting block 413 simultaneously drives the first slide block 41 to move, thus realizing the structural function of the pushing assembly in pushing the first slide block 41 to slide back and forth.

[0038] In addition, the aforementioned cutting tool opening machine also includes a control device 9. The first motor 2 and the second motor 42 are electrically connected to the control device 9, and the control device 9 controls the operation of the first motor 2 and the second motor 42, which makes the operation more convenient.

[0039] As an improvement to this embodiment, such as Figure 1 , 2 As shown, a second slide block 5 is slidably mounted on the workbench 1. The second slide block 5 can slide left and right relative to the workbench 1. A first slide block 41 is slidably fitted onto the second slide block 5 and can slide back and forth relative to the second slide block 5. A fixing plate 51 is provided on the rear side of the second slide block 5. A second motor 42 is fixed in front of the fixing plate 51 at a position corresponding to the position above the first slide block 41. A first lead screw 43 is rotatably connected to the fixing plate 51. The driving gear 421 and the driven gear 431 are both located on the rear side of the fixing plate 51. In use, when the second slide block 5 is pushed to slide left and right, the first slide block 41 and the repair wheel 12 will move accordingly, thus adjusting the left and right position of the repair wheel 12.

[0040] like Figure 6 , 8 As shown, a second connecting block 52 is provided below the second slide block 5. A second lead screw 6 is rotatably connected to the worktable 1, and a turntable 61 is connected to the outer end of the second lead screw 6. The second lead screw 6 and the second connecting block 52 are threadedly connected. In use, the second lead screw 6 can be rotated by rotating the turntable 61. The rotation of the second lead screw 6 will cause the second connecting block 52 to move left and right along the second lead screw 6. The movement of the second connecting block 52 will drive the second slide block 5 to move. In other words, the second slide block 5 can be driven to move left and right by rotating the turntable 61, making operation more convenient.

[0041] Example 3

[0042] This embodiment is a further improvement on the structure of the cutting tool threading machine in Embodiment 2. The improvement is as follows: Figure 3 , 4As shown, the aforementioned blade fixing mechanism includes a base plate 8 rotatably connected to the worktable 1. Two opposing catches 83 are arranged on the worktable 1. The lower end of the base plate 8 is rotatably connected to the two catches 83 via a third rotating shaft 84, allowing the base plate 8 to rotate relative to the two catches 83 via the third rotating shaft 84. The base plate 8 has two lower stops 81 and two opposing side stops 82 on its side opposite to the grinding wheel 11. Slots are formed on the upper sides of the two lower stops 81, and the side stops 82 are located to the left and right of the two lower stops 81, respectively. In use, the blade 80 is inserted into the slot between the corresponding side stops 82. At this time, the side stops 82 abut against both ends of the blade 80, thus fixing the blade 80. The lower stops 81 and the base plate 8 prevent the blade 80 from moving downwards or forwards, while the side stops 82 prevent the blade 80 from moving left or right, thus accurately fixing the blade 80. Pulling the blade 80 upwards allows it to be removed, making disassembly and assembly convenient.

[0043] like Figure 1 , 3 As shown in Figure 5, a water spraying device and a water-blocking cover 7 are provided on the workbench 1 above the grinding wheel 11. The water spraying device is located inside the water-blocking cover 7. When in use, turning on the water spraying device will spray water onto the grinding wheel 11 and the blade 80 to achieve cooling and dust reduction. The water-blocking cover 7 can prevent the water sprayed by the water spraying device from spraying everywhere. Specifically, a support rod 72 is provided on the support 14 on the left side, and the water-blocking cover 7 is fixed on the support rod 72 to ensure the installation stability of the water-blocking cover 7. The workbench 1 is provided with a drain outlet 10 so that the water sprayed by the water spraying device can be discharged from the drain outlet 10 for recycling.

[0044] The aforementioned water spraying device is a water pipe 71 inserted inside the water-blocking cover 7. The water pipe 71 has an inlet for connecting to a water source. The side wall of the section of the water pipe 71 inside the water-blocking cover 7 has multiple water outlets. A switch 711 is located near the inlet of the water pipe 7. In use, the inlet of the water pipe 71 is connected to the water source, and then the switch 711 is turned on. Water will flow into the water pipe 7 and spray out from the water outlets, thus spraying water on the grinding wheel 11 and the blade 80.
