Description

Technical Field

[0001] The utility model relates to the technical field of tool grinding, in particular to a detachable tool grinding machine. Background Technique

[0002] A tool grinding machine is a professional device for repairing and grinding tools, which is widely used in industrial production. Such machines have various models and functions to meet the grinding requirements of different types of tools.

[0003] At present, most grinding methods are carried out by manually holding a grinding device. The quality of the ground cutting edges is uneven. Even worse, there are often cases where the entire tool is damaged due to grinding failure, which seriously affects the quality. Moreover, after long-term grinding, the inside of the device needs to be cleaned and parts need to be replaced. Most devices use bolts and welding to seek stability, making it very time-consuming to replace the inside.

[0004] Therefore, we propose a detachable tool grinding machine to solve the problems mentioned above. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a detachable tool grinding machine, including a grinding machine main body 1 and an upper cover 16. There are upper covers 16 arranged on both sides of the top of the grinding machine main body 1, and a pull rod 8 is installed on the top of the upper cover 16. A water injection pipe 9 is connected to the center of the top of the upper cover 16, and a water spray head 10 is installed at one end of the water injection pipe 9. Upper fixing plates 11 are connected to both sides of the bottom of the upper cover 16. Mounting frames 3 are connected to both sides of the grinding machine main body 1, and a motor 2 is installed inside the mounting frame 3, and a grinding stone 17 is installed at the output end of the motor 2. A connecting plate 6 is connected above the mounting frame 3, and a fixing structure 7 is arranged at the top end of the connecting plate 6. Fixed blocks 5 are installed on both sides of the bottom of the grinding machine main body 1, and a lower fixing plate 4 is arranged inside the fixed blocks 5. Fixed blocks 5 are installed on the inner bottom of the grinding machine main body 1. A water collection tank 12 is installed at the bottom of the grinding machine main body 1, and a water outlet pipe 13 is connected to the front end of the water collection tank 12. A tool slot 15 is opened on the front side of the grinding machine main body 1, and a baffle 14 is installed at the front end of the grinding machine main body 1.

[0022] A notch corresponding to the upper cover 16 is opened at the top of the grinding machine main body 1, and the upper cover 16 is clamped with the grinding machine main body 1 through the notch. When internal parts are damaged, by pulling the pull rod 8, the whole upper cover 16 is pulled to expose the internal parts, so as to quickly find the damaged internal parts.

[0023] Rotating shafts are arranged on both sides of the bottom of the grinding machine main body 1, and the mounting frame 3 is rotatably connected with the grinding machine main body 1 through the rotating shafts. By pulling the whole upper cover 16, the upper fixing plate 11 connected to the bottom of the upper cover 16 is lifted together, thereby releasing the fixation of the grinding stone 17. Then, the mounting frame 3 is rotated out of the grinding machine main body 1 through the rotating shafts to expose the grinding stone 17, so as to facilitate the replacement of the grinding stone 17 and reduce the maintenance time.

[0024] The grinding stones 17 are centrosymmetric, and the inclination angle between the grinding stones 17 is 30°. The tool to be ground is placed between the grinding stones 17 through the tool slot 15 for grinding. The grinding debris flows to the water collection tank 12 through the inclined grinding stones 17 and then flows out through the water outlet pipe 13 on the front side of the water collection tank 12 for centralized treatment, so as to reduce the internal cleaning time.

[0025] The fixing structure 7 includes a fixing rod 701, a pulling block 702, a pressing block 703 and a spring 704. A spring 704 is installed at the bottom of the pressing block 703, and the bottom of the spring 704 is arranged on the connecting plate 6. A fixing rod 701 is installed on the left side of the pressing block 703, and a pulling block 702 is arranged on the right side of the pressing block 703. By pressing the pressing block 703, the spring 704 at the bottom of the pressing block 703 is compressed and contracted, so that the fixing rod 701 installed on the left side of the pressing block 703 moves downward, thereby releasing the fixing of the fixing rod 701 on the connecting plate 6, facilitating the disassembly and maintenance of internal parts.

[0026] Working principle: When using this detachable tool grinding machine, first, start the power supply of the motor 2 to make the grinding stone 17 connected to the output end of the motor 2 rotate. Then, place the tool to be ground through the tool slot 15 between the grinding stones 17. The tool handle is placed on the baffle 14 for grinding. And the water spray head 10 inside the upper cover 16 injects water through the water injection pipe 9 for spraying water to cool it down.

[0027] Next, the grinding debris flows to the water collection tank 12 through the inclined grinding stone 17 and then flows out through the water outlet pipe 13 on the front side of the water collection tank 12 for centralized treatment, reducing the internal cleaning time.

[0028] Finally, after the grinding machine is used for a long time, the internal parts need to be replaced regularly. At this time, by pulling the pull rod 8, the whole upper cover 16 is pulled, so that the upper fixing plate 11 connected to the bottom of the upper cover 16 is pulled up together, thereby releasing the fixing of the grinding stone 17. Then, by pressing the pressing block 703 in the fixing structure 7, the spring 704 at the bottom of the pressing block 703 is forced to contract, so that the fixing rod 701 installed on the left side of the pressing block 703 moves downward, releasing the fixing of the fixing rod 701 on the connecting plate 6. Then, pull the pulling block 702 to lift the mounting frame 3 from the top of the fixing block 5 and the lower fixing plate 4, and then rotate it out of the grinding machine main body 1 through the rotating shaft, so that the grinding stone 17 is presented outside for replacement, reducing the maintenance time. And the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
