Technical Field
[0001] This utility model relates to the field of grinding machine technology, specifically a grinding machine that facilitates grinding wheel replacement. Background Technology
[0002] A grinding wheel machine is a common piece of equipment used to sharpen various cutting tools and tools. It is also used for grinding, deburring, and cleaning ordinary small parts. It mainly consists of a base, grinding wheel, electric motor or other power source, bracket, protective cover, and water supply device.
[0003] Chinese patent publication number "CN216098108U" discloses "an easy-to-maintain benchtop grinder, including a processing table, an opening on the processing table, a connecting shaft inserted into the inner side of the opening, and a fixed mounting plate sleeved on the outer wall of the connecting shaft, a first motor provided on one side of the processing table and connected to the connecting shaft, the fixed mounting plate having a "U"-shaped structure, a grinder base plate provided on the top of the fixed mounting plate, and a benchtop grinder body provided on the top of the grinder base plate." This patent, by setting an automatically rotating fixed mounting plate on the processing table and a splicing plate at the front end of the processing table, achieves [the desired effect]. The existing patented design involves mounting the main body of a bench grinder on top of a fixed mounting plate. During maintenance, the mounting plate is rotated to expose the base plate of the grinder. The left and right sides of the main body are then fixed by limiting clamps on the splicing plate, facilitating maintenance. However, this design only makes the grinder as a whole easy to assemble and disassemble from the workbench, not easy to remove the grinding wheel. This means that when removing the grinding wheel, the operator needs to hold the edge of the grinding wheel to pull it off, which can easily cut the operator's hands and is inconvenient for disassembly. Therefore, we propose a grinder that facilitates grinding wheel replacement. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. This grinding wheel machine, which facilitates wheel replacement, uses a third motor to drive a bidirectional lead screw to rotate. This causes the bidirectional lead screw to move a slider, which in turn moves a connecting rod. The connecting rod then moves a push plate to the left, causing the push plate to push the grinding wheel body out of the grinding wheel protective housing. This allows the device to automatically remove the grinding wheel without manual removal.
[0020] 2. This grinding machine, which facilitates wheel replacement, allows adjustment of the dust collection hood position by bending the gooseneck rod. Then, by activating the vacuum cleaner, the dust generated during grinding is sucked away in conjunction with the dust collection hood, preventing air pollution. The vacuum cleaner then discharges the sucked-up dust into the dust collection box, where filter plates filter the dust-laden air. Finally, a second motor drives a brush to rotate, cleaning the filter plates and preventing clogging. This effectively removes dust and prevents pollution of the working environment.

[0030] This utility model provides a grinding wheel machine that facilitates grinding wheel replacement. It automatically ejects the grinding wheel, eliminating the need for manual removal, and also removes dust, preventing pollution of the working environment. Please refer to [link / reference]. Figure 1-5 It includes a base 100 and a base plate 200;
[0031] Please see Figure 1 , Figure 2 and Figure 5 A work box 110 is fixedly connected to the top of the base 100. A first motor 120 is fixedly connected to the right side wall of the inner cavity of the work box 110. A rotating shaft 130 is fixedly connected to the end of the power output shaft of the first motor 120.

A partition 170 is fixedly connected between the inner side walls of dust collector 160. A filter plate 171 is embedded in the center of the top of the partition 170. A fixing plate 180 is fixedly connected to the lower rear side wall of the inner cavity of dust collector 160. The top of the fixing plate 180 is fixed... A dust cover 181 is fixedly connected to the dust cover 181. A second motor 182 is fixedly connected to the bottom of the inner cavity of the dust cover 181. The end of the power output shaft of the second motor 182 passes through the dust cover 181 and extends to the top of the dust cover 181. A brush 183 is fixedly connected to the power output shaft of the second motor 182. A vacuum cleaner 190 is fixedly connected to the left side wall of the dust collection box 160. The vacuum cleaner 190 is connected to the dust collection box 160 and the dust collection hood 292 through a telescopic hose. By bending the gooseneck rod 291... The position of the dust collection hood 292 is adjusted, and the vacuum cleaner 190 is started to work with the dust collection hood 292 to suck up the dust generated during grinding, thereby preventing dust from polluting the air. Then, the vacuum cleaner 190 discharges the sucked-up dust into the dust collection box 160, so that the filter plate 171 filters the dust gas, thereby filtering down the dust. Finally, the second motor 182 drives the brush 183 to rotate, so that the brush 183 cleans the filter plate 171, thereby preventing the filter plate 171 from becoming clogged.
[0032] In summary, this allows the device to remove dust and prevent pollution of the working environment.
[0033] Please see Figure 1-4A base plate 200 is fixedly connected to the left side wall of the base 100. A support plate 210 is fixedly connected to the top of the base plate 200. A grinding wheel protective shell 220 is fixedly connected to the top of the support plate 210. A side plate 221 is screwed to the left side wall of the grinding wheel protective shell 220. Slide grooves 230 are provided on the upper and lower sides of the right side wall of the inner cavity of the grinding wheel protective shell 220. A third motor 240 is fixedly connected to the top and bottom right sides of the grinding wheel protective shell 220. A double-acting lead screw 250 is fixedly connected to the end of the power output shaft of the third motor 240. The end of the double-acting lead screw 250 passes through the grinding wheel protective shell 220 and extends into the inner cavity of the slide groove 230. Slide grooves 230 are screwed to the upper and lower sides of the outer side wall of the double-acting lead screw 250. A slider 260 is rotatably connected to a connecting rod 270 on its left side wall. A push plate 280 is rotatably connected to the end of the connecting rod 270. A vertical rod 290 is fixedly connected to the top of the grinding wheel protective shell 220. A gooseneck rod 291 is fixedly connected to the upper side of the front side wall of the vertical rod 290. A dust collection hood 292 is fixedly connected to the end of the gooseneck rod 291. A third motor 240 drives a bidirectional lead screw 250 to rotate, which in turn drives the slider 260 to move. The slider 260 then drives the connecting rod 270 to move, which in turn drives the push plate 280 to move to the left. This causes the push plate 280 to push the grinding wheel body 150 out of the grinding wheel protective shell 220.
[0034] In summary, this allows the device to automatically eject the grinding wheel without requiring manual removal.
[0035] In practical use, those skilled in the art first install the device at the work site, then adjust the position of the dust collection hood 292 by bending the gooseneck rod 291, and then drive the grinding wheel body 150 to rotate via the first motor 120 to grind the workpiece. Simultaneously, the vacuum cleaner 190 is activated to work in conjunction with the dust collection hood 292 to suck away the grinding dust, which is then discharged into the dust collection box 160, allowing the filter plate 171 to filter the dusty gas. Subsequently, the second motor 182 drives the brush 183 to rotate, causing the brush 183 to clean the filter plate 171 and prevent clogging. After grinding, open valve 163 to allow the filtered dust to be discharged from slag discharge pipe 162. When the grinding wheel needs to be replaced, remove the side plate 221 from the grinding wheel protective shell 220 and unscrew the bolts fixing the grinding wheel body 150. Then, drive the double-acting screw 250 to rotate via the third motor 240, causing the double-acting screw 250 to move the slider 260. The slider 260 then drives the connecting rod 270 to move, causing the connecting rod 270 to move the push plate 280 to the left. This push plate 280 pushes the grinding wheel body 150 off the mounting plate 140, allowing the grinding wheel body 150 to be quickly removed.
