Description

Technical Field

[0001] This utility model relates to the field of lawnmower blade grinding technology, specifically a quick-clamping lawnmower blade grinding device. Background Technology

[0002] Previously, people used manual tools such as sickles to mow lawns, which was inefficient, labor-intensive, and resulted in inconsistent trimming quality. With rapid urbanization and rising demands for quality living environments, people are paying more attention to their surroundings, leading to the proliferation of large lawns. These large lawns require more efficient mowing methods, which spurred the invention and development of lawnmowers. A lawnmower is a mechanical device used to trim lawns, grasslands, and other vegetation. A crucial component is the lawnmower's blade. To ensure a good cutting effect, the blade needs to be ground and sharpened after production. This allows the blade to cut and break up the grass more easily when installed inside the lawnmower. However, common blade sharpening devices typically use screws to fix the blade, resulting in low efficiency when installing and removing the blade. Prolonged screw installation and removal can also damage the mounting base, making it inconvenient to use and reducing processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a quick-clamping lawnmower blade grinding device to solve the problem mentioned in the background art where the blade mounting using screws is inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-clamping lawnmower blade grinding device, comprising a mounting frame, a sliding rail frame fixedly mounted on the outer surface of one end of the mounting frame, and a movable platform slidably mounted on the outer surface of the sliding rail frame; a rotating mounting column rotatably mounted on the outer surface of the mounting frame, and a drive servo motor fixedly mounted on the side surface of the rotating mounting column, with the output end of the drive servo motor penetrating through the outer surface of the rotating mounting column; a slip ring fixedly mounted on the outer surface of the rotating mounting column away from the drive servo motor, and a magnetic attraction engagement mechanism is provided between the slip ring and the drive servo motor, which makes blade mounting and dismounting easier and more efficient.

[0005] Preferably, the magnetic fastening mechanism includes: a mounting base, which is plugged into and fixedly installed at the output end of the drive servo motor, and the drive servo motor is connected to the other end of the slip ring; a ring electromagnet is fixedly installed on one outer surface of the mounting base, and the circuit of the ring electromagnet is connected to the slip ring; a clamp base is fixedly installed on one outer surface of the mounting base, and the clamp base and the drive servo motor are concentrically designed; a rubber pad is provided on the outer surface of the clamp base; a clamp head is inserted into one side of the clamp base, and the clamp head and the clamp base are concentrically designed; a toothed block is fixedly installed on one outer surface of the clamp head, and the toothed block can be inserted into the interior of the clamp base, and the interior of the clamp base engages with the toothed block; the clamp head and the clamp base are in contact with the outer surface of the cutter head.

[0006] By adopting the above technical solution, different sizes and models of tool discs can be clamped and fixed by changing different clamping bases and clamping heads. When it is necessary to fix the tool disc, simply place the tool disc into the clamping base and insert the clamping head into the clamping base so that the cleaving block can enter the clamping base. Then, by rotating the clamping head, the cleaving block can be moved along with it. Then, the ring electromagnet can be activated. The magnetic force generated by the ring electromagnet will attract the clamping head and the tool disc simultaneously. After the clamping head is attracted, it will be fully inserted into the clamping base and clamp the tool disc. At the same time, the side of the cleaving block will engage with the clamping base, allowing the tool disc to be quickly clamped and fixed. Rubber pads prevent the tool disc from slipping when rotating slowly, allowing the tool disc to be quickly fixed on the clamping base. This reduces the cumbersome process of raising and lowering the tool disc and improves the efficiency of grinding and machining the tool disc.

[0007] Preferably, a control module is provided on the outer surface of the end of the mounting frame near the rotating mounting column, and a rotating engagement mechanism is provided on the end of the rotating mounting column located inside the mounting frame. The orientation and angle of the rotating mounting column can be easily adjusted through the rotating engagement mechanism, so that the cutter head can grind different cutting angles as required.

[0008] Using the above technical solution, the control module can control the ring electromagnet, drive servo motor, screw motor assembly, grinding wheel motor assembly and suction pump, and can adjust the angle of the rotating mounting column according to processing requirements to adjust and grind the cutting edge angle of the cutter head.

[0009] Preferably, the rotating meshing mechanism includes: a worm gear fixedly mounted on the outer surface of the rotating shaft of the rotating mounting column; a worm rotatably mounted on the side of the mounting frame near the worm gear, and the worm meshes with the worm gear; and a handwheel is provided at one end of the worm located outside the mounting frame.

[0010] By adopting the above technical solution, the rotation angle of the rotating mounting column can be easily adjusted by the handwheel at one end of the worm gear. At the same time, the self-locking property of the worm wheel and worm gear ensures that the rotating mounting column will not rotate on its own after the angle is adjusted and determined, thus preventing machining errors.

[0011] Preferably, one end of the rotating mounting column near the worm gear penetrates the outer surface of the mounting frame, and a portion of the angle gear assembly is fixedly mounted on the outer surface of the mounting frame, while the other portion of the angle gear assembly is connected to the rotating shaft of the rotating mounting column.

[0012] Using the above technical solution, after the worm gear is rotated by turning the handwheel, the worm wheel that meshes with it will rotate, and the angle gear assembly installed at one end of the rotating mounting column will rotate along with it. This allows the worker to know the rotation angle of the rotating mounting column in real time through the angle gear assembly, making the angle of the cutter head for processing and grinding clear at a glance.

[0013] Preferably, a screw motor assembly is fixedly installed on the outer surface of the sliding track frame, and the output end of the screw motor assembly is threadedly connected to the moving platform, and the output end of the screw motor assembly is rotatably connected to the mounting frame. A grinding wheel motor assembly is fixedly installed on the outer surface of the moving platform.

[0014] By adopting the above technical solution, the rotation of the screw motor assembly can drive the moving platform to move on the outer surface of the sliding track frame, so that the grinding wheel motor assembly installed on the outer surface of the moving platform can move along with it. By adjusting the screw motor assembly, the distance between the moving platform and the cutter head can be controlled, so that the feed rate between the grinding wheel motor assembly and the cutter head can be controlled, which is convenient for processing cutter heads of different sizes.

[0015] Preferably, a liquid separation plate is fixedly installed on the outer surface of the sliding track frame, and the liquid separation plate has strip-shaped protrusions inside, with different heights of the strip-shaped protrusions. A suction pump is fixedly installed inside the liquid separation plate, and a spray head is fixedly installed on the outer surface of the moving platform near the suction pump, and the spray head is connected to the suction pump.

[0016] Using the above technical solution, a suction pump can extract the coolant from the liquid separation plate and send it into the spray head. The coolant sprayed from the spray head can cool the cutting disc being ground, preventing it from annealing and being damaged. At the same time, the falling coolant will be settled and filtered through strip-shaped protrusions of different heights inside the liquid separation plate, allowing the metal powder in the coolant to be separated and the coolant to be recycled.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the quick-clamping lawnmower blade grinding device:

[0018] 1. When grinding, simply insert the cutter head into the outer surface of the fixture base, then insert the fixture head into the interior of the fixture base and lift it slightly so that the cleaver teeth inserted into the fixture base can rotate. Then, activate the annular electromagnet to magnetize the fixture base, so that the fixture base can attract the fixture head and the cutter head. Through the attraction of the annular electromagnet, the cleaver teeth can move and engage with the interior of the fixture base, so that the fixture base and the fixture head will not separate due to external force when the cutter head is rotating during processing. This saves the time spent installing and removing screws, making the installation and removal of the cutter head simpler and faster.

[0019] 2. By turning the handwheel, the worm gear can be driven to rotate, and the worm wheel meshing with the worm gear can also rotate, thereby driving the rotating mounting column and the drive servo motor to rotate together, thus changing the tilt angle of the cutter head. At the same time, due to the self-locking property of the worm wheel and worm gear, the rotating mounting column will not automatically change after the angle is adjusted, reducing the danger and damage to the cutter head caused by angle changes during processing. The cutter head can change the grinding and sharpening angle according to the processing requirements.

[0020] 3. The rotation of the screw motor assembly can drive the moving platform to move on the sliding track frame, so that the distance between the grinding wheel motor assembly and the cutter head can be adjusted, and the feed rate of the grinding wheel motor assembly can be adjusted, so that cutter heads of different sizes and different cutting angles can be processed. In conjunction with the rotation of the drive servo motor, the cutter head can be processed faster.

[0021] 4. As the grinding wheel motor assembly grinds the cutter head, the suction pump draws out the coolant stored in the liquid separation plate and sends it into the spray head. This allows the coolant sprayed from the spray head to directly hit the cutter head during grinding, cooling it down and ensuring the quality of the ground cutter head. Meanwhile, the falling coolant will pass through the liquid separation plate for sedimentation and separation, allowing the metal in the coolant to be separated and recycled, thus ensuring the quality of the cutter head after processing and grinding.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a quick-clamping lawnmower blade grinding device, including a mounting frame 1, a sliding rail frame 2 fixedly mounted on the outer surface of one end of the mounting frame 1, and a moving platform 15 slidably mounted on the outer surface of the sliding rail frame 2. A rotating mounting column 3 is rotatably mounted on the outer surface of the mounting frame 1, and a drive servo motor 10 is fixedly mounted on the side surface of the rotating mounting column 3. The output end of the drive servo motor 10 passes through the outer surface of the rotating mounting column 3. A slip ring 4 is fixedly mounted on the outer surface of the rotating mounting column 3 away from the drive servo motor 10, and a magnetic attraction and fastening mechanism is provided between the slip ring 4 and the drive servo motor 10. The magnetic attraction and fastening mechanism makes it easier and more efficient to install and remove the blade.

[0031] By slowly rotating the servo motor 10, the cutter head can be rotated, and the edge of the cutter head can be ground in one go in conjunction with the rotation of the grinding wheel motor assembly 16, thereby improving the processing and grinding efficiency of the cutter head. At the same time, the slip ring 4 allows the annular electromagnet 5 to still be powered and used when the servo motor 10 is rotating.

[0032] The magnetic locking mechanism includes: a mounting base 6, which is plugged into and fixedly installed at the output end of the drive servo motor 10, and the drive servo motor 10 is connected to the other end of the slip ring 4. A ring electromagnet 5 is fixedly installed on one outer surface of the mounting base 6, and the circuit of the ring electromagnet 5 is connected to the slip ring 4. A clamp base 7 is fixedly installed on one outer surface of the mounting base 6, and the clamp base 7 and the drive servo motor 10 are concentrically designed. The outer surface of the clamp base 7 is provided with a rubber pad, and a clamp head 8 is inserted into one side of the clamp base 7. The clamp head 8 and the clamp base 7 are concentrically designed. A toothed block 9 is fixedly installed on one outer surface of the clamp head 8, and the toothed block 9 can be inserted into the interior of the clamp base 7. The interior of the clamp base 7 engages with the toothed block 9. The clamp head 8 and the clamp base 7 are in contact with the outer surface of the cutter head.

[0033] When grinding the cutter head is required, the corresponding fixture base 7 and fixture head 8 need to be taken. Then, the fixture base 7 is fixed on the outer surface of the mounting base 6, and the cutter head can be placed on the fixture base 7. The fixture head 8 is then inserted into the fixture base 7. The fixture head 8 is then slightly lifted and rotated so that the retaining block 9 can be rotated and inserted into the fixture base 7. Then, the annular electromagnet 5 is activated so that the annular electromagnet 5 can magnetize the fixture base 7, so that the fixture base 7 can generate magnetism and attract the fixture head 8 and the cutter head. Through the attraction of the fixture head 8 by the annular electromagnet 5, the retaining block 9 can be inserted into the fixture base 7. The rubber pad prevents the cutter head from slipping, so that the fixture base 7 and the fixture head 8 can clamp and fix the cutter head. When the drive servo motor 10 drives the fixture base 7 to rotate, the fixture head 8 will not be separated from the fixture base 7 due to external forces or other reasons. This allows the cutter head to be installed and removed quickly without the need for screws.

[0034] A control module is provided on the outer surface of the mounting frame 1 near the rotating mounting column 3, and a rotating engagement mechanism is provided on the end of the rotating mounting column 3 located inside the mounting frame 1. The orientation and angle of the rotating mounting column 3 can be easily adjusted through the rotating engagement mechanism, so that the cutter head can grind different cutting angles as required.

[0035] The electrical components on the grinding device are operated and controlled by the control module on the outer surface of the mounting frame 1. At the same time, the grinding angle of the cutter head can be adjusted by rotating the mounting column 3, so that the cutting head can adjust the sharpening and grinding angles according to the processing requirements.

[0036] The rotating meshing mechanism includes: a worm gear 11, which is fixedly installed on the outer surface of the rotating shaft of the rotating mounting column 3; a worm 12 is rotatably installed in the mounting frame 1 on the side near the worm gear 11, and the worm 12 meshes with the worm gear 11; and a handwheel is provided at one end of the worm 12 located outside the mounting frame 1.

[0037] When the grinding angle of the cutter head needs to be adjusted, simply rotate the worm gear 12 by handwheeling. This will drive the worm wheel 11, which meshes with the worm gear 12, so that the rotating mounting column 3 can drive the drive servo motor 10 to rotate. This allows the clamping base 7, clamping head 8, and cutter head at one end of the drive servo motor 10 to rotate together. The self-locking property of the worm wheel 11 and worm gear 12 ensures that the rotating mounting column 3 will not rotate on its own after the angle is adjusted, reducing the danger caused by the change of the angle of the rotating mounting column 3 during processing and the damage to the cutter head.

[0038] One end of the rotating mounting column 3 near the worm gear 12 passes through the outer surface of the mounting frame 1, and a part of the angle gear assembly 13 is fixedly mounted on the outer surface of the mounting frame 1, and the other part of the angle gear assembly 13 is connected to the rotating shaft of the rotating mounting column 3.

[0039] When the angle of the rotating mounting column 3 changes, it will drive the angle gear assembly 13 installed at one end of the rotating mounting column 3 to rotate together. In conjunction with the other part of the angle gear assembly 13 on the outer surface of the mounting frame 1, the tilt angle of the rotating mounting column 3 can be known in real time, making the angle of the machining cutter head clear at a glance and reducing the probability of machining errors.

[0040] A screw motor assembly 14 is fixedly installed on the outer surface of the sliding track frame 2, and the output end of the screw motor assembly 14 is threadedly connected to the moving platform 15. The output end of the screw motor assembly 14 is rotatably connected to the mounting frame 1. A grinding wheel motor assembly 16 is fixedly installed on the outer surface of the moving platform 15.

[0041] The rotation of the screw motor assembly 14 enables the moving platform 15 to move on the outer surface of the sliding track frame 2, which in turn drives the grinding wheel motor assembly 16 to move together. This allows the distance between the grinding wheel motor assembly 16 and the cutter head to be adjusted, making it easier to control the feed rate of the grinding wheel motor assembly 16 during grinding and enabling the processing of cutter heads of different sizes.

[0042] A liquid separation plate 17 is fixedly installed on the outer surface of the sliding track frame 2. The liquid separation plate 17 has strip-shaped protrusions inside, and the height of the strip-shaped protrusions in the liquid separation plate 17 is different. A suction pump 18 is fixedly installed inside the liquid separation plate 17. A spray head 19 is fixedly installed on the outer surface of the moving platform 15 near the suction pump 18, and the spray head 19 is connected to the suction pump 18.

[0043] During the grinding of the cutter head, the suction pump 18 pumps the coolant stored in the liquid separation plate 17 into the spray head 19. The position of the spray head 19 is adjusted so that the coolant sprayed from the spray head 19 can directly hit the cutter head being ground, allowing the cutter head to be cooled during grinding to ensure the quality of grinding. At the same time, the coolant that falls will return to the liquid separation plate 17. Through the strip-shaped protrusions of different heights set in the liquid separation plate 17, the metal powder in the coolant is separated, so that the coolant pumped by the suction pump 18 will not contain metal particles. This allows the coolant to be recycled, cooling the cutter head while ensuring the quality of grinding.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
