Description

Technical Field

[0001] This utility model relates to the technical field of saw blade sharpening, specifically a sharpening device for diamond saw blades that can be stably clamped. Background Technology

[0002] In modern industry and construction, diamond saw blades are widely used as a high-efficiency cutting tool for processing hard and brittle materials such as stone, ceramics, and concrete. The cutting performance of diamond saw blades largely depends on the quality of their cutting edge, and sharpening is a key process to ensure that the saw blade has good cutting ability. Since the saw blade is subjected to various external forces such as grinding force and impact force during the sharpening process, if it is not clamped firmly, the saw blade is prone to displacement, shaking, or even falling off, which will seriously affect the accuracy and quality of sharpening.

[0003] To address the aforementioned deficiencies, the existing technology (Chinese Patent No. CN222470944U, Publication Date 2025-02-14) provides a diamond saw blade sharpening device. When sharpening a diamond saw blade is required, the diamond saw blade needs to be clamped. The diamond saw blade is placed between a first clamping plate and a second clamping plate. Then, a push-pull rod is pushed, causing the push-pull rod to drive the plug to insert into the slot. Rotating the second clamping plate brings it closer to the first clamping plate, thereby clamping and fixing the diamond saw blade.

[0004] In the above solution, when sharpening the diamond saw blade, the clamp is fixed at the center of the saw blade, while the grinding edge is located at the edge of the saw blade. The lever arm is relatively long from the center, so when grinding the edge, the saw blade will still wobble due to the grinding force, which will affect the processing quality and safety. Utility Model Content

[0005] The purpose of this invention is to provide a stable clamping device for sharpening diamond saw blades, in order to solve the problem mentioned in the background art where the existing diamond saw blade sharpening device fixes the center of the saw blade to the clamping plate, while the grinding edge is located at the edge of the saw blade. The lever arm is relatively long from the center, so when grinding the edge at the edge, the saw blade still shakes under the grinding force, which affects the processing quality and safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sharpening device for a diamond saw blade that can be stably clamped, comprising a base, wherein a first column is symmetrically connected to the front and rear sides of the top right side of the base via a first cylinder, a drive motor is provided at the top of the first column, and a positioning plate is connected to the output end of the drive motor via a connecting frame, the positioning plate abutting against the center of the saw blade body; a second column is symmetrically provided to the top left side of the base via a second cylinder, and a fixing plate is connected to the top of the second column via a fixing frame, wherein a dual-axis motor is installed inside the fixing plate, and a grinding wheel for sharpening the saw blade body is connected to the right output of the dual-axis motor;

[0007] An extension frame is installed at equal angles on the outer side of the positioning plate, and a positioning plate is slidably connected in the extension frame. The positioning plate clamps and positions the edge of the saw blade body.

[0008] A nozzle is slidably connected to the left side of the second column. The nozzle is connected to the water tank via a water pump. The nozzle and the water pump are fixed to the left side of the second column.

[0009] Furthermore, the connecting frame drives the positioning plate to clamp and fix the saw blade body at the center. A rotating rod is rotatably connected to the outer center of the positioning plate. The end of the rotating rod is connected to the screw through a bevel tooth connector. The screw is rotatably connected to the inside of the extension frame at an equal angle. The outer side of the screw is threadedly connected to the positioning plate.

[0010] Furthermore, the positioning plate forms a telescopic sliding structure with the extension frame via a screw, which increases the stability of the saw blade body during sharpening.

[0011] Furthermore, the positioning plate is configured with an "L"-shaped structure, and the positioning plate and the positioning disk form a stable multi-point positioning structure. The length of the positioning plate is adjusted according to the radius of the saw blade body.

[0012] Furthermore, a small gear is connected to the left output end of the dual-axis motor inside the fixed plate, and a large gear is meshed below the small gear. The large gear is rotatably connected to the horizontal plate, and the horizontal plate is fixed to the side of the water tank.

[0013] Furthermore, the large gear is provided with a guide groove, which is designed in a flower shape. A longitudinal rod is slidably connected in the guide groove, and the outer side of the longitudinal rod is slidably connected in a rectangular limiting groove. The limiting groove is opened through the horizontal plate, and the longitudinal rod forms a horizontal sliding structure through the guide groove and the limiting groove.

[0014] Furthermore, a spray pipe is fixed in the middle of the longitudinal rod, and the spray pipe is slidably mounted on the top of the fixed plate. The spray pipe forms a spray cooling structure through the longitudinal rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This diamond saw blade sharpening device with stable clamping can position and clamp the saw blade at the center and around the perimeter during use by setting up a positioning plate and positioning disc, reducing the lever arm during sharpening and avoiding shaking. At the same time, it sprays water to cool down during sharpening to prevent high temperatures from damaging the diamond saw blade and grinding wheel.

[0017] 1. Furthermore, the positioning plate is fixed to the center of the saw blade body. While the positioning plate is positioning, the positioning plate in the extension frame can clamp and fix the edge of the saw blade body, thereby maintaining the stability of the saw blade body and preventing the saw blade body from shaking during sharpening, which would affect the processing quality and safety. At the same time, when sharpening saw blade bodies of different specifications, the rotating rod on the outside of the positioning plate is rotated. After the rotating rod rotates, it drives the screw to rotate synchronously through the bevel tooth connector. After the screw rotates, it drives the positioning plate to extend in the extension frame, thereby changing the positioning and clamping range and adapting to different sizes of saw blade bodies.

[0018] 2. Furthermore, the dual-axis motor drives the grinding wheel to rotate while simultaneously driving the pinion to rotate. The pinion then drives the large gear below to rotate synchronously. The large gear then drives the guide groove to rotate, which in turn drives the longitudinal rod to move. The longitudinal rod is then limited by the limiting groove on the horizontal plate, which prevents it from moving horizontally back and forth. The movement of the longitudinal rod drives the nozzle to move synchronously. The nozzle can both cool the saw blade body and reduce dust during sharpening. Attached Figure Description
