[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-5, the present utility model provides a technical solution: a high-precision adjustable external cylindrical grinding machine, including an equipment working bottom box 1; in order to be able to perform rough and fine grinding processing simultaneously, a grinding mechanism 2 is provided on the equipment working bottom box 1, a fixing mechanism 3 is provided on the equipment working bottom box 1, a waste water collection box 7 is installed inside the equipment working bottom box 1, and a drain port 8 is opened on one side of the equipment working bottom box 1. Grinding is carried out through the grinding mechanism 2, and the height of the workpiece is adjusted through the fixing mechanism 3;

[0024] In order to achieve the function of simultaneous rough and fine precision grinding, the grinding mechanism 2 includes a grinding moving plate 207. The grinding moving plate 207 is installed above the equipment working bottom box 1. A moving plate motor 213 is installed on one side of the grinding moving plate 207. A moving plate lead screw 214 is installed on the moving plate motor 213. The grinding moving plate 207 is installed on the moving plate lead screw 214. A first mounting plate 205 and a second mounting plate 206 are installed on the grinding moving plate 207. A first grinding machine box 200 is installed on the first mounting plate 205. A second grinding box 201 is installed on the second mounting plate 206. Grinding motors 202 are installed on both the first grinding machine box 200 and the second grinding box 201. A first grinding wheel 203 is installed on the first grinding machine box 200. A second grinding wheel 204 is installed on the second grinding box 201. A first push rod motor 209 is installed on one side of the first mounting plate 205. A first push rod 211 is installed on the first push rod motor 209. A second push rod motor 210 is installed on one side of the second mounting plate 206. A second push rod 212 is installed on the second push rod motor 210. The first push rod 211 is connected to the first mounting plate 205. The second push rod 212 is connected to the second mounting plate 206. A grinding moving chute 4 is opened on the equipment working bottom box 1. A moving plate slider 208 is installed at the bottom of the grinding moving plate 207. The moving plate slider 208 is installed in the grinding moving chute 4. A waste water trough 6 is opened on the equipment working bottom box 1. A waste water collection box 7 is installed at the inner bottom. A drain port 8 is internally communicated with the waste water collection box 7. Fix both ends of the workpiece on the fixed chucks 301 respectively. The precision of the first grinding wheel 203 and the second grinding wheel 204 is inconsistent. The precision of the first grinding wheel 203 is higher than that of the second grinding wheel 204. When rough and fine grinding needs to be carried out synchronously, first drive the moving plate lead screw 214 to rotate through the moving plate motor 213. When the moving plate lead screw 214 rotates, it drives the grinding moving plate 207 to move on the moving plate lead screw 214. First move the moving plate lead screw 214 to the edge close to the first grinding wheel 203. Then move the fixed sliding plate 302. When the fixed sliding plate 302 moves, it slides on the fixed lifting block 304 through the sliding plate chute 303. Move the fixed sliding plate 302 to make the surface of the workpiece close to the edge of the grinding wheel. The grinding motors 202 drive the two grinding wheels to rotate respectively. When grinding, the moving plate motor 213 drives the moving plate lead screw 214 to rotate, and the moving plate lead screw 214 drives the grinding moving plate 207 to move towards the side of the moving plate motor 213. Thus, when the first grinding wheel 203 and the second grinding wheel 204 move, they can gradually grind the surface of the workpiece along the axis direction of the moving plate lead screw 214. During grinding, the second grinding wheel 204 with rough precision first contacts the workpiece for rough grinding, and then the first grinding wheel 203 contacts the workpiece for secondary fine grinding. When only one precision grinding wheel needs to be used, if only the first grinding wheel 203 needs to be used, contract the second push rod 212 through the second push rod motor 210. When the second push rod 212 contracts, the second mounting plate 206 drives the second grinding wheel 204 to move.At this time, the first grinding wheel 203 and the second grinding wheel 204 are not on the same straight line. At this time, the workpiece can only contact the first grinding wheel 203. If only the second grinding wheel 204 is used, reset the second push rod 212, and contract the first push rod 211 through the first push rod motor 209, thereby driving the first grinding wheel 203 to move. At this time, the workpiece can only contact the second grinding wheel 204. When the diameters of the installed workpieces are different.,

[0025] The working principle is as follows: Fix both ends of the workpiece on the fixed chuck 301 respectively. The precisions of the first grinding wheel 203 and the second grinding wheel 204 are inconsistent. The precision of the first grinding wheel 203 is higher than that of the second grinding wheel 204. When rough and fine grinding need to be carried out synchronously, first drive the moving plate lead screw 214 to rotate through the moving plate motor 213. When the moving plate lead screw 214 rotates, it drives the grinding moving plate 207 to move on the moving plate lead screw 214. First, move the moving plate lead screw 214 to the edge close to the first grinding wheel 203. Then move the fixed sliding plate 302. When the fixed sliding plate 302 moves, it slides on the fixed lifting block 304 through the sliding plate chute 303. Move the fixed sliding plate 302 so that the surface of the workpiece is close to the edge of the grinding wheel. The grinding motors 202 drive the two grinding wheels to rotate respectively. When grinding, the moving plate motor 213 drives the moving plate lead screw 214 to rotate, and the moving plate lead screw 214 drives the grinding moving plate 207 to move towards the side of the moving plate motor 213. Thus, when the first grinding wheel 203 and the second grinding wheel 204 move, they can gradually grind the surface of the workpiece along the axial direction of the moving plate lead screw 214. During grinding, the second grinding wheel 204 with rough precision first contacts the workpiece for rough grinding, and then the first grinding wheel 203 contacts the workpiece for secondary fine grinding. When only one precision grinding wheel needs to be used, if only the first grinding wheel 203 needs to be used, contract the second push rod 212 through the second push rod motor 210. When the second push rod 212 contracts, the second mounting plate 206 drives the second grinding wheel 204 to move. At this time, the first grinding wheel 203 and the second grinding wheel 204 are not on the same straight line. At this time, the workpiece can only contact the first grinding wheel 203. If only the second grinding wheel 204 is used, reset the second push rod 212, and contract the first push rod 211 through the first push rod motor 209, thereby driving the first grinding wheel 203 to move. At this time, the workpiece can only contact the second grinding wheel 204. When the diameters of the installed workpieces are different, in order to ensure the machining precision, when grinding, it is necessary to make the grinding wheel contact the maximum outer diameter surface of the workpiece. Drive the lifting push rod 306 to lift and lower through the fixed lifting motor 305. When the lifting push rod 306 lifts and lowers, it can drive the fixed lifting block 304 to lift and lower. The fixed lifting block 304 drives the fixed sliding plate 302 and the fixed frame 300 to move. When the fixed frame 300 moves, it drives the workpiece fixed on the fixed chuck 301 to lift and lower. Thus, the height of the workpiece can be adjusted by lifting, so that when workpieces of different diameters are installed, the machining precision of the finished product can be maintained.

[0026] Embodiment 2: As Figures 1-4 , in order to be able to adjust the height of the workpiece, the fixing mechanism 3 includes a fixing frame 300, the fixing frame 300 is installed above the working bottom box 1 of the equipment, a fixing chuck 301 is installed on the fixing frame 300, a fixing lifting motor 305 is installed inside the working bottom box 1 of the equipment, a lifting push rod 306 is installed on the fixing lifting motor 305, a fixing lifting block 304 is installed on the lifting push rod 306, a fixing slide plate 302 is installed on the fixing lifting block 304, the fixing frame 300 is installed on the fixing slide plate 302, a slide plate chute 303 is opened on the fixing slide plate 302, the fixing lifting block 304 is installed in the slide plate chute 303, a fixing lifting groove 5 is opened on the working bottom box 1 of the equipment, the fixing lifting block 304 is installed in the fixing lifting groove 5. In order to ensure the machining accuracy, when grinding, it is necessary to make the grinding wheel contact the maximum outer diameter surface of the workpiece. The lifting push rod 306 is driven by the fixing lifting motor 305 to lift and lower. When the lifting push rod 306 lifts and lowers, it can drive the fixing lifting block 304 to lift and lower. The fixing lifting block 304 drives the fixing slide plate 302 and the fixing frame 300 to move. When the fixing frame 300 moves, it drives the workpiece fixed on the fixing chuck 301 to lift and lower. Thus, the height of the workpiece can be adjusted by lifting, so that when installing workpieces with different diameters, the machining accuracy of the finished product can be maintained. The other features are the same as those in Embodiment 1.
