Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding wheel device technology, and in particular to a grinding wheel device for tool grinding. Background Technology
[0002] Grinding wheels, also known as bonded abrasives, are abrasives in which ordinary abrasive grains are bonded together with a bonding agent to form a certain shape and have a certain strength. They are generally composed of abrasive grains, a bonding agent, and pores. Grinding wheels are the most widely used and applicable type of abrasive. They rotate at high speeds during use and can be used for rough grinding, semi-fine grinding, and fine grinding of the outer and inner circles, planes, and various profiles of metal or non-metal workpieces, as well as grooving and cutting.
[0003] Grinding wheels are generally disc-shaped and are typically used at high speeds to grind the surface of cutting tools. During the sharpening and grinding of cutting edges, workers need to manually deflect the tool so that the cutting edge contacts the grinding wheel at an angle to complete the grinding. However, this manual tilting grinding method requires a high level of skill from the worker. Not only does the worker need to accurately control the tilt angle, but they also need to maintain this posture for a long time. During long working hours, workers are prone to physical fatigue, which increases the risk of poor tool grinding quality due to operational errors. Therefore, a grinding wheel device for tool grinding is proposed. Utility Model Content

[0034] Example 1
[0035] Reference Figures 1-3 The first embodiment of this utility model provides a grinding wheel device for sharpening tools, including: a grinding table 100, a grinding unit 200, a lifting unit 300, a limiting unit 400, and a wetting unit 500.
[0036] The grinding unit 200 is mounted on the grinding table 100 and is used to grind the cutting tool.
[0037] The lifting unit 300 is installed on the grinding table 100. The lifting unit 300 is equipped with a limit unit 400. The lifting unit 300 is used to lift the limit unit 400, and the limit unit 400 is used to limit the movement direction of the tool.
[0038] The wetting unit 500 is installed on the grinding table 100 and is used to wet the cutting tool.
[0039] When sharpening the blade, the wetting unit 500 wets the blade to reduce its temperature, clean debris from its surface, and lubricate it to improve the sharpening effect. Then, the lifting unit 300 raises the limiting unit 400 to limit the blade, preventing it from tilting and allowing it to move only in a straight line. This allows the sharpening unit 200 to directly sharpen the blade. After the blade is sharpened, the sharpening unit 200 polishes the surface of the blade.
[0040] Example 2
[0041] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, the grinding unit 200 includes a support frame 201 fixedly connected to the top of the grinding table 100. A servo motor 202 is fixedly installed on one side of the support frame 201. The output shaft of the servo motor 202 passes through the support frame 201 and is fixedly sleeved with a mounting plate 203. A first grinding wheel 204 is fixed to one side of the mounting plate 203 by bolts. A second grinding wheel 205 is fixed to one side of the first grinding wheel 204 by bolts. The opposing surfaces of the first grinding wheel 204 and the second grinding wheel 205 are both provided with a symmetrical chamfer.
[0042] The chamfered angles of the first grinding wheel 204 and the second grinding wheel 205 can form a ring-shaped V-shaped space. When sharpening the cutting edge, the servo motor 202 drives the first grinding wheel 204 and the second grinding wheel 205 to rotate. Then, the cutting tool is placed at the bottom of the first grinding wheel 204 and the second grinding wheel 205, and the lifting unit 300 and the limiting unit 400 limit the cutting tool so that both sides of the cutting edge contact the chamfered surfaces of the first grinding wheel 204 and the second grinding wheel 205 respectively. At this time, the cutting edge can be sharpened by the chamfered surfaces, so that the cutting tool does not need to be tilted, thereby reducing the burden on the worker and improving the sharpening efficiency. The first grinding wheel 204 and the second grinding wheel 205 can be disassembled and replaced, so that the first grinding wheel 204 and the second grinding wheel 205 with different chamfer angles can be used for sharpening according to different cutting edges. After the cutting edge is sharpened, the worker can manually sharpen the surface of the cutting tool.
[0043] Specifically, a portal plate 206 is fixedly connected to one side of the support frame 201, and a bearing 207 that passes through the portal plate 206 is fixedly connected to one side of the portal plate 206. The output shaft of the servo motor 202 passes through the inner ring of the bearing 207.
[0044] The output shaft of the servo motor 202 is fixed to the inner ring of the bearing 207. When the output shaft of the servo motor 202 rotates, the bearing 207 and the gate plate 206 can support the output shaft, and the bearing 207 can reduce the vibration of the output shaft of the servo motor 202 during rotation, so as to improve the stability of grinding.
[0045] Example 3
[0046] Reference Figures 1-3 This is the third embodiment of the present invention. Unlike the previous embodiment, the lifting unit 300 includes an electric telescopic rod 301 fixedly installed at the bottom of the grinding table 100. The output shaft of the electric telescopic rod 301 passes through the top of the grinding table 100, and a concave plate 302 is fixedly connected to the output end of the electric telescopic rod 301.
[0047] The concave plate 302 is located directly below the inclined surfaces of the first grinding wheel 204 and the second grinding wheel 205. The electric telescopic rod 301 is used to drive the concave plate 302 to move vertically up and down.
[0048] In addition, the limiting unit 400 includes two electric push rods 401, which are fixed on both sides of the concave plate 302 respectively. The output shafts of the two electric push rods 401 slide through the concave plate 302, and the output ends of the two electric push rods 401 are fixedly connected to clamping plates 402.
[0049] When it is necessary to sharpen the blade, the blade is placed between two clamping plates 402. Then, two electric push rods 401 push the two clamping plates 402 closer together and keep the blade in a vertical position. The two clamping plates 402 do not clamp the blade, so that the blade can move with the two clamping plates 402 in a vertical position, so that the worker can move the blade and sharpen the blade.
[0050] Specifically, straight plates 403 are fixedly connected to the opposite surfaces of the two clamping plates 402, and multiple round rods 404 are rotatably connected to the top of the two straight plates 403.
[0051] When the two clamping plates 402 approach each other, the round rods 404 on the two straight plates 403 will contact each other before the two sides of the tool. The round rods 404 can limit the tool. The round rods 404 can rotate, allowing the tool to move between multiple round rods 404. This reduces the friction between the round rods 404 and the tool, making it easier for the worker to pull the tool to move.
[0052] Example 4
[0053] Reference Figure 1 and Figure 2 This is the fourth embodiment of the present utility model. Unlike the previous embodiment, the wetting unit 500 includes a water storage box 501 disposed on the top of the grinding table 100, and the top of the grinding table 100 is provided with a mounting groove that fits the water storage box 501.
[0054] The water storage box 501 is slidably disposed in the mounting groove to prevent the water storage box 501 from slipping off the grinding table 100. By adding clean water into the water storage box 501, the cutting tool can be immersed in the water to wet the cutting tool so that the first grinding wheel 204 and the second grinding wheel 205 can grind it. During the grinding process, immersing the cutting tool in water can also clean the debris on the surface of the cutting tool.
[0055] Specifically, the inner wall of the water storage box 501 is fixedly connected to multiple partitions 502, and each partition 502 has a gap with the bottom of the inner cavity of the water storage box 501.
[0056] The partition 502 is used to prevent the blade from sinking directly into the water. The partition 502 prevents the blade from sticking to the bottom of the water storage box 501, so that workers can quickly remove the blade from the water storage box 501.
[0057] During use, the knife is first placed in the water storage box 501 and moistened with clean water. Then, the knife is placed between two clamping plates 402. Next, two electric push rods 401 push the two clamping plates 402 closer to each other, and the round rods 404 on the two straight plates 403 limit the two sides of the knife to keep the knife in a vertical position. Then, the servo motor 202 drives the first grinding wheel 204 and the second grinding wheel 205 to rotate, and the electric telescopic rod 301 drives the concave plate 302 to rise, so that the two sides of the blade contact the inclined surfaces of the first grinding wheel 204 and the second grinding wheel 205 respectively. At this time, the blade can be directly ground through the inclined surfaces.
[0058] During the sharpening process, the worker can manually push and pull the tool to keep it in a vertical position for all-round sharpening. After the tool is sharpened, the electric telescopic rod 301 moves the concave plate 302 downwards, and then the two electric push rods 401 pull the two clamping plates 402 away from each other. The worker then removes the tool from the concave plate 302 and washes it with clean water in the water storage box 501. After washing, the surface of the tool is sharpened using the first grinding wheel 204 and the second grinding wheel 205.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
