[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-7The utility model provides a technical solution: a tool production blade grinding machine, including a motor box 1, a frame 5, a clamping arm 8, a grinding stone 12, a water spray pipe 14, a water tank 17, a support leg 18 and a clamping block 27. The motor box 1 is arranged above the frame 5, and the motor 2 is installed inside the motor box 1. Transmission frames 4 are arranged on both sides of the motor box 1, and gears 3 are arranged in the transmission frame 4. The gears 3 are installed on both sides of the motor 2. Travel switches 19 are installed on both sides of the transmission frame 4. The clamping frame 7 is connected to the bottom of the motor box 1, and a slide rail 21 is installed inside the clamping frame 7. A connecting rod 23 is provided on the slide rail 21, and a clamping arm 8 is fixed on the connecting rod 23. A fixing plate 25 is installed on the clamping arm 8, and a sleeve is connected in the middle of the fixing plate 25. Rod 24, a spring 6 is fixed to the outside of the sleeve rod 24, a clamping block 27 is connected to the lower end of the clamping arm 8, and a limiting rod 26 is provided on the clamping block 27, a fixed block 22 is fixed to the outside of the clamping frame 7, and a knob 9 is installed on the fixed block 22, and a baffle 10 is connected to the knob 9, a movable plate 11 is provided inside the frame 5, and a spring 2 13 is fixed to the lower end of the movable plate 11, and a grinding stone 12 is connected to the front end of the spring 2 13, an electric cylinder 15 is installed at the lower end of the movable plate 11, and a drain outlet 20 is provided at the bottom of the movable plate 11, a supporting leg 18 is fixed to the bottom of the frame 5, and a water tank 17 is installed on the supporting leg 18, a water pump 16 is provided inside the water tank 17, and a water spray pipe 14 is connected to the water pump 16.

[0028] A tooth structure is provided inside the transmission frame 4. The connection between the gear 3 and the transmission frame 4 is a meshing connection. The motor 2 drives the gear 3 to rotate, and the reciprocating motion of the motor box 1 is achieved through the cooperation between the gear 3 and the transmission frame 4.

[0029] The transmission frame 4 and the frame body 5 are integrated, the motor box 1 and the clamping frame 7 are integrated, and the frame body 5 and the motor box 1 form a sliding structure through rollers, so that the friction resistance of the frame body 5 to the motor box 1 is reduced when the motor box 1 moves back and forth, thereby assisting the motor box 1 to move.

[0030] The connection between the knob 9 and the baffle 10 is a fixed connection. The rotation angle of the knob 9 is 0°~90°, and a spring clip is provided above the knob 9. The baffle 10 is driven by the knob 9 to rotate, blocking the clamping arm 8 to prevent the clamping arm 8 from slipping out when the clamping frame 7 moves. When rotated to 90°, the spring clip is embedded in the knob 9 to prevent the knob 9 from rotating.

[0031] The clamping block 27 is magnetic to pre-fix the tool, preventing the clamping arm 8 from suddenly loosening when the tool is taken out after grinding, causing the tool to fall. The limit rod 26 can keep the tool in the same position when clamped. There are multiple groups of clamping arms 8, which are evenly spaced on the connecting rod 23, so that the device can clamp multiple tools for grinding at the same time, thereby improving the working efficiency of the device.

[0032] The connection between the clamping arm 8 and the connecting rod 23 is a fixed connection, the connection between the sleeve rod 24 and the fixed plate 25 is a movable rod connection, and the connection between the fixed plate 25 and the clamping arm 8 is a fixed connection. The width between the two connecting rods 23 is slightly larger than the width of the clamping frame 7. The connecting rod 23 realizes a sliding structure in the clamping frame 7 through the slide rail 21. The width between the two connecting rods 23 is reduced through the clamping frame 7 to complete the clamping of the tool, thereby avoiding the movement of the tool during grinding, which affects the grinding effect.

[0033] The bottom of the movable plate 11 is inclined, so that water can be better discharged from the frame 5. The front end of the grinding stone 12 is semicircular, and there are multiple groups of them symmetrically arranged. One end of the spring 2 13 is in contact with the grinding stone 12, but is not fixed, so that the grinding stone 12 is easy to disassemble and replace. The other end is fixedly connected to the movable plate 11. The grinding stone 12 forms a sliding structure on the movable plate 11 through the spring 2 13, which can grind both sides of the tool at the same time, thereby improving the grinding efficiency of the device. The movable plate 11 is driven up and down by the electric cylinder 15, so that tools of different lengths and cutting edges of different angles can be ground, thereby improving the practicality of the device.

[0034] Working principle: When using the tool to produce a knife edge grinder, first pull up the spring buckle above the knob 9, rotate the knob 9, drive the baffle 10 to rotate, take out the clamping arm 8 through the slide rail 21, and place the tool on the clamping block 27. The clamping block 27 is magnetic to pre-fix the tool, so as to avoid the clamping arm 8 suddenly loosening when the tool is taken out after grinding, causing the tool to fall. The limit rod 26 is used to keep the tools at the same height, and push the clamping arm 8 with the pre-fixed tool into the clamping frame 7. The clamping frame 7 reduces the width between the two connecting rods 23 to complete the clamping of the tool.

[0035] Then turn on the motor 2 in the motor box 1, and the motor 2 drives the gear 3 to rotate. The gear 3 cooperates with the transmission frame 4 to realize the reciprocating motion of the motor box 1. The motor box 1 and the clamping frame 7 are integrated. The reciprocating motion of the motor box 1 drives the clamping frame 7 to move, and then drives the tool to move. Turn on the switch of the electric cylinder 15, so that the electric cylinder 15 drives the movable plate 11 to move, so that the grinding stone 12 on the movable plate 11 is located in the appropriate position, and the tool is ground in the middle of the grinding stone 12. Springs 13 are provided on both sides of the grinding stone 12 to squeeze the grinding stone 12 to better grind the tool.

[0036] During the grinding process, the water pipe 14 will spray water onto the tool and the grinding stone 12 to make the grinding work smoother. The excess water will be discharged from the drain port 20 along the inclined structure at the bottom of the movable plate 11 and enter the water tank 17. A water pump 16 is provided inside the water tank 17, and the water pump 16 is connected to the water pipe 14 to recycle the water in the device. This is the working process of the tool production blade grinder, and the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
