[0001] This utility model relates to the field of grinding device technology, specifically a motor shaft grinding device. Background Technology

[0002] One of the commonly used equipment for grinding motor shafts in cylindrical grinding machines, its main structure includes: a grinding wheel holder (for mounting the grinding wheel), a headstock (for mounting the workpiece), a tailstock, a worktable, etc. The high-speed rotation of the grinding wheel is the main motion, while the rotation of the workpiece (driven by the headstock) and the reciprocating movement of the worktable are the feed motions. The outer diameter of the workpiece is ground, which can realize the efficient grinding operation of the motor shaft. In the prior art, when an external cylindrical grinding machine grinds a motor shaft, grinding fluid is used to cool and dissipate heat from the grinding area of ​​the motor shaft. At the same time, in order to prevent the grinding fluid from splashing onto the operator, a protective shell is used to protect and block the front of the processing area. However, in actual use, the grinding fluid splashes onto the transparent window on the protective shell, causing the transparent window to become blurry, which in turn affects the operator's observation of the grinding process of the motor shaft. Based on this, a motor shaft grinding device is provided. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-4 In this embodiment of the utility model, a motor shaft grinding device includes an external cylindrical grinding machine 1. An L-shaped rail groove 2 is provided on the front end face of the worktable of the external cylindrical grinding machine 1. An anti-splash component 3 is installed on the external cylindrical grinding machine 1 through the L-shaped rail groove 2. The anti-splash component 3 is used to intercept the splashed grinding fluid. Splash protection component 3 includes a protective unit and a spray unit; The protective unit moves to the front of the grinding area to intercept the splashing grinding fluid generated during grinding; The spray unit is used to spray the surface of the protective unit to prevent grinding fluid from adhering to the surface of the protective unit and causing blurred vision; The protective unit includes a protective baffle 301, a transparent observation window 302, and a handle 303; The protective baffle 301 is distributed at the front end of the worktable of the external cylindrical grinding machine 1 and is horizontally slidably connected to the L-shaped rail groove 2. The transparent observation window 302 is embedded in the inner side of the protective baffle 301. The handle 303 is fixed to the front end of the protective baffle 301 and distributed below the transparent observation window 302. The protective baffle 301 is moved to the front of the grinding area to intercept the splashed grinding fluid, and the transparent observation window 302 is used for the operator to observe the grinding process; The blowing unit includes a blower hood 304, a horizontal pipe 305, a nozzle 306, and an external fixing pipe 307; The blower hood 304 is fixed to the bottom of one end face of the protective baffle 301 near the cylindrical grinding machine 1. The horizontal tube 305 is fixedly installed inside the blower hood 304. The nozzle 306 is fixed to the bottom of the horizontal tube 305 and communicates with the inner cavity of the horizontal tube 305. The external fixing tube 307 is distributed at the front end of the protective baffle 301 and the top of the external fixing tube 307 penetrates through the top of the protective baffle 301 to the inside of the blower hood 304. The external fixing tube 307 is connected to the horizontal tube 305. The bottom end of the external fixing pipe 307 extends to the bottom of the protective baffle 301 and is connected to an external air pump through a hose; The channel consisting of the external fixed pipe 307, the horizontal pipe 305, and the nozzle 306 is used to allow air to flow and spray onto the surface of the transparent observation window 302, thereby achieving the surface cleaning operation of the transparent observation window 302.

[0015] In this embodiment, it should be noted that the external cylindrical grinding machine 1 is a common model of external cylindrical grinding machine on the market, and its operating principle is exactly the same. Therefore, its operating structure will not be described in detail here. After the motor shaft is clamped by the headstock (which drives the workpiece to rotate via the spindle) and the tailstock (which has a movable center to support the workpiece), the protective baffle 301 can be moved along the L-shaped rail to the front of the grinding area in the middle of the cylindrical grinding machine 1. When the cylindrical grinding machine 1 is running, the protective baffle 301 and the transparent observation window 302 intercept the splashing grinding fluid, thereby preventing the grinding fluid from splashing onto the workers. (It should be noted that a safety door interlock device can be installed on the protective baffle 301. When the cylindrical grinding machine 1 is running, the protective baffle 301 is fixed in the middle position of the cylindrical grinding machine 1. The safety door interlock device is a mature product on the market and is widely used in the locking of lathe safety doors.) During this process, the grinding fluid remaining on the surface of the transparent observation window 302 can cause the viewing line of the transparent observation window 302 to become blurred. Therefore, the air pump connected to the external fixed pipe 307 can be started. The air pump will deliver high-pressure air to the external fixed pipe 307, and then enter the horizontal pipe 305 and be sprayed out through the nozzle 306. The sprayed airflow blows from top to bottom onto the surface of the transparent observation window 302 through the lower opening of the blower hood 304, causing the grinding fluid remaining on the surface of the transparent observation window 302 to be blown downward and flow quickly. This achieves the effect of avoiding the grinding fluid remaining on the surface of the transparent observation window 302, keeping the transparent observation window 302 clear, and thus facilitating the observation of the grinding of the motor shaft.

[0016] Please refer to this carefully. Figures 1-4 Multiple nozzles 306 are evenly arranged along the long side of the horizontal tube 305, and the port of the blower hood 304 is tilted towards the surface of the transparent observation window 302. A concave guide plate 308 is also fixed at one end of the protective baffle 301 near the cylindrical grinding machine 1. The concave guide plate 308 is distributed at the bottom of the transparent observation window 302, and the bottom end of the concave guide plate 308 is inclined towards the worktable of the cylindrical grinding machine 1.

[0017] In this embodiment, it should be noted that the distribution length of the nozzle 306 is greater than the lateral length of the transparent observation window 302, thus enabling the transparent observation window 302 to be fully sprayed. The length of the concave guide plate 308 is greater than the distribution length of the nozzle 306. The concave guide plate 308 is used to receive the grinding fluid flowing down from the surface of the transparent observation window 302 and guide it to the worktable of the external cylindrical grinding machine 1 (it should be noted that the worktable of the external cylindrical grinding machine 1 is provided with a collection tank for guiding and collecting the grinding fluid, and the collection tank is connected to the grinding fluid recovery device through a pipe).

[0018] Please refer to this carefully. Figures 1-2 The L-shaped rail groove 2 extends from one side of the worktable of the external cylindrical grinding machine 1 to the middle area of ​​the external cylindrical grinding machine 1, and the external fixed pipe 307 is close to the moving and storing direction of the protective baffle 301.

[0019] In this embodiment, the structure allows the protective baffle 301 to be stored on one side of the cylindrical grinding machine 1, thus distributing the flexible hose connected to the external fixed pipe 307 on one side of the cylindrical grinding machine 1 without affecting the loading and unloading operation of the cylindrical grinding machine 1.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
