Description

Technical Field

[0001] The utility model belongs to the technical field of numerically controlled external cylindrical grinders, and in particular relates to a numerically controlled external cylindrical grinder with protective measures. Background Art

[0002] Cylindrical grinding machines are used to process the outer surfaces of cylindrical, conical or other shaped workpieces and the shoulder end faces. They are the most widely used grinding machines and can process various cylindrical and conical outer surfaces and shoulder end faces.

[0003] Among all the grinding machines, cylindrical grinding machine is the most widely used type of machine tool. It is generally composed of a cast iron bed as the basic part, a worktable, a headstock and tailstock that support and drive the workpiece to rotate, a grinding wheel frame (grinding head) for installing the grinding wheel, a lateral feed mechanism that controls the size of the grinding workpiece, and electrical and hydraulic devices that control the movement of the moving parts of the machine tool. In the use of CNC external grinding machines, cutting fluid plays an important role. Cutting fluid is used to lubricate and cool the tool, which can reduce the friction between the tool and the machined surface, form a partial lubricating film, thereby reducing cutting force, friction and power consumption, reduce the surface temperature and tool wear of the friction part between the tool and the workpiece blank, improve the cutting performance of the workpiece material, and effectively reduce the cutting temperature, reduce the thermal deformation of the workpiece and the tool, and at the same time clean up the grinding chips generated during processing to prevent the machine tool, workpiece and tool from being contaminated, so as to keep the cutting edge of the tool or grinding wheel sharp and avoid affecting the cutting effect.

[0004] During use, the cutting fluid is sprayed on the tool and the workpiece, and the cutting fluid takes away a lot of powdered iron chips from the tool and the workpiece. Since there are no protective devices around the workpiece and the tool, the cutting fluid splashes around as the tool rotates. The cutting fluid adheres to the slide seat and needs to be cleaned regularly. Otherwise, when adjusting the use position of the chuck seat or the ejector seat, the grinding chips will cause scratches on the surface of the adjusting chuck seat or the ejector seat, affecting the smoothness of the adjustment.

[0026] Through the arrangement of the first protective plate 9, the second protective plate 13 and the third protective plate 14, in actual use, the second protective plate 13 and the third protective plate 14 at both ends of the first protective plate 9 are slidably installed together, and then the third protective plates 14 at both ends of the protective mechanism are respectively fixed to the spindle system 2 and the transverse feed system 3. The edge of the end of the third protective plate 14 fixed to the spindle system 2 and the transverse feed system 3 is provided with a rubber pad to prevent the cutting fluid from flowing into the slide from the gap. The second protective plate 13 and the third protective plate 14 can move with the movement of the spindle system 2 and the transverse feed system 3 to ensure that the protective mechanism can always cover the top of the slide during work to prevent iron chips from entering the slide and causing the precision of parts such as the transverse feed system 3 and the spindle system 2 to decrease.

[0027] Further, see Figure 3-5 As shown, it is worth noting that a first slide rail 8 is fixedly connected to the top surface of the first protective plate 9, a second slide rail 16 is slidably arranged in the first slide rail 8, the second slide rail 16 is connected to the second protective plate 13, a third slide rail 15 is slidably arranged in the second slide rail, and the third slide rail 15 is fixedly connected to the top surface of the third protective plate 14;

[0031] A slide groove 12 is provided on the outer wall of the baffle 11, and a slider matching the slide groove 12 is fixed to the top of the support rod 10;

[0032] A rubber layer is glued on the outer wall of the sliding block, and the rubber layer is tightly fitted to the inner wall of the sliding groove 12;

[0033] Through the setting of the baffle 11, during the process of processing the workpiece, one end of the baffle 11 is pulled up to the top of the workpiece. At this time, the rubber layer on the outer wall of the slider is tightly fitted with the inner wall of the slide groove 12, and there is a large friction force to prevent the baffle 11 from sliding off, so that the baffle 11 completely covers the side of the workpiece away from the grinding wheel 5. After the processing is completed, the baffle 11 is pulled to the bottom of the workpiece through the setting of the slide groove 12 and the slider, which makes it convenient to take the workpiece, can further reduce the splash of cutting fluid, and also reduce the maintenance cost.
