Description

Technical Field

[0001] This utility model relates to the field of hand saw production, and in particular to a hand saw tooth grinding processing device. Background Technology

[0002] As a common manual cutting tool, the hand saw is widely used in many fields such as construction, woodworking, and gardening. Among them, the saw tooth processing is a key part of its production process, and the grinding quality of the saw teeth directly affects the cutting performance and service life of the hand saw.

[0003] In the current field of hand saw tooth grinding, common processing equipment mainly consists of a grinding power unit, a worktable, and a simple clamping mechanism. The grinding power unit typically uses a motor to drive the grinding wheel to rotate at high speed to provide the cutting force required for grinding. The worktable is used to place the hand saw to be processed. The operator manually places the hand saw on the worktable and clamps the saw blade using the clamping mechanism. Most existing clamping mechanisms use bolts, nuts, or simple clamp structures to press the saw blade onto the worktable, which is complex to operate, inefficient in clamping, and reduces production efficiency.

[0004] Therefore, a saw tooth grinding device for hand saws has been developed that can facilitate stable clamping and holding of saw blades, improve the clamping efficiency and stability of saw blades, and increase the production efficiency of hand saws. Utility Model Content

[0005] To overcome the shortcomings of existing hand saw tooth grinding processes, which mostly rely on bolts, nuts, or simple clamping structures to press the saw blade onto the worktable, resulting in complex operation, low clamping efficiency, and reduced production efficiency, this utility model provides a hand saw tooth grinding device that facilitates stable clamping of the saw blade, improves the clamping efficiency and stability of the saw blade, and enhances the production efficiency of hand saws. Technical solution

[0006] A saw blade grinding device includes a protective cover, a rodless cylinder, a slider, a grinding machine, a mold, a rack, a clamping frame, gears, guide rods, a first telescopic spring, and a pressing assembly. The rodless cylinder is connected to the upper side of the protective cover, and the slider is slidably connected to the rodless cylinder. The grinding machine is mounted on the slider. The mold is detachably connected to the bottom of the protective cover. Racks are slidably connected to both the front and rear sides of the mold. Gears are rotatably connected inside the mold, and the racks mesh with the gears. A clamping frame is connected to the ends of the racks that are far apart from each other. Guide rods are connected to both the left and right sides inside the mold. The clamping frames are slidably connected to the adjacent guide rods. A first telescopic spring is connected between the clamping frames and the adjacent guide rods. A sliding sleeve is connected to the upper front side of the mold. The mold is equipped with a pressing assembly that can press and fix the saw blade.

[0007] Furthermore, the protective cover is equipped with a transparent observation window.

[0008] Furthermore, a cone-shaped waste discharge port is provided on the lower side of the protective cover.

[0009] Furthermore, it also includes a lever, which is connected to the front rack.

[0010] Furthermore, the pressing assembly includes a guide plate, a pressing frame, a sliding sleeve, a second telescopic spring, and a screw sleeve. The pressing frame is slidably connected to the sliding sleeve. The upper side of the clamping frame is connected to the guide plate, and the guide plate is slidably engaged with the pressing frame. The clamping frame is connected to the sliding sleeve with a second telescopic spring. The screw sleeve is slidably and rotatably connected to the clamping frame, and the screw sleeve is threadedly connected to the sliding sleeve.

[0011] Furthermore, each guide plate has a folded guide groove.

[0012] The beneficial effects of this utility model are as follows: By sliding the lever to the left, the clamping frame slides inward on the guide rod. During the sliding of the clamping frame, the sliding cooperation between the guide plate and the pressing frame allows the pressing frame to slide downward on the sliding sleeve to press the saw blade. This achieves the effect of facilitating stable clamping of the saw blade, improving the clamping efficiency and stability of the saw blade, and increasing the production efficiency of the hand saw.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] A hand saw tooth grinding processing device, such as Figures 1-5 As shown, the assembly includes a protective cover 1, a rodless cylinder 2, a slider 3, a grinding machine 4, a mold 5, a lever 6, a rack 7, a clamping frame 8, a gear 9, a guide rod 10, a first telescopic spring 11, and a pressing assembly. The rodless cylinder 2 is connected to the upper side of the protective cover 1. The protective cover 1 has a transparent observation window, and a conical waste discharge port is located on the lower side of the protective cover 1. The slider 3 is slidably connected to the rodless cylinder 2, and the grinding machine 4 is mounted on the slider 3. The mold 5 is detachably connected to the bottom of the protective cover 1. The mold 5 has two sides... A rack 7 is slidably connected, and a lever 6 is connected to the front rack 7. A gear 9 is rotatably connected inside the mold 5. All racks 7 mesh with gears 9. A clamping frame 8 is connected to the ends of racks 7 that are far apart from each other. Guide rods 10 are connected to the left and right sides inside the mold 5. The clamping frame 8 is slidably connected to the adjacent guide rod 10. A first telescopic spring 11 is connected between the clamping frame 8 and the adjacent guide rod 10. A sliding sleeve 14 is connected to the upper front part of the mold 5. A pressing component is provided on the mold 5.

[0021] like Figure 5 As shown, the pressing assembly includes a guide plate 12, a pressing frame 13, a sliding sleeve 14, a second telescopic spring 15, and a screw sleeve 16. The pressing frame 13 is slidably connected to the sliding sleeve 14. The upper side of the clamping frame 8 is connected to the guide plate 12. The guide plate 12 has a folded guide groove. The guide plate 12 is slidably engaged with the pressing frame 13. The second telescopic spring 15 is connected between the clamping frame 8 and the sliding sleeve 14. The screw sleeve 16 is slidably and rotatably connected to the clamping frame 8. The screw sleeve 16 is threadedly connected to the sliding sleeve 14.

[0022] When using this invention, first place the device at the saw tooth grinding position of the hand saw. Then, open the observation window on the protective cover 1, place the saw blade under the pressing frame 13 on the mold 5, and then slide the lever 6 to the left, causing the front rack 7 to slide to the left. Through the meshing motion of the rack 7 and the gear 9, the gear 9 rotates, driving the rear rack 7 to slide to the right, causing the clamping frame 8 to slide inward on the guide rod 10. The first telescopic spring 11 is stretched. During the sliding of the clamping frame 8, the guide plate 12 slides inward. Through the sliding cooperation between the guide plate 12 and the pressing frame 13, the pressing frame 13 slides downward on the sliding sleeve 14. The second telescopic spring... The tensioning mechanism 15 allows the clamping frame 8 to hold and fix the saw blade while the pressing frame 13 presses the saw blade firmly. Then, the pressing frame 13 is fixed by tightening the screw sleeve 16 onto the sliding sleeve 14. After that, the grinding machine 4 and the rodless cylinder 2 can be started, so that the slider 3 drives the grinding machine 4 to process the saw teeth on the saw blade. After the saw teeth are processed, simply loosen the screw sleeve 16, and the first extension spring 11 and the second extension spring 15 will rebound, causing the clamping frame 8 to move outward and the pressing frame 13 to move upward. Then, the processed saw blade can be taken out. This makes it easier to press and clamp the saw blade smoothly, improves the clamping efficiency and stability of the saw blade, and improves the production efficiency of the hand saw.
