DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-5 A casting corner cutting device shown in the figure includes a workbench 1, the top of the workbench 1 is provided with two rectangular grooves, two hydraulic cylinders 2 are arranged in the two rectangular grooves, a U-shaped plate 3 is fixedly installed on the output ends of the four hydraulic cylinders 2, the relative inner walls of the U-shaped plate 3 are slidably installed with sliders 4 through sliding components, the relative sides of the two sliders 4 are rotatably installed with mounting shafts, a grinding motor 9 is fixedly installed on the side of one of the sliders 4, the output shaft of the grinding motor 9 is connected to the end of the mounting shaft, a grinding roller 10 is fixedly sleeved on the mounting shaft, a limiting plate 11 is fixedly installed on the top of the workbench 1, a sliding hole is provided on the top of the workbench 1, an L-shaped slide plate 12 is slidably installed in the slide hole through a moving component, a fixed plate 15 is fixedly installed on the top of the L-shaped slide plate 12, and a clamping component is arranged on the side of the fixed plate 15.

[0024] With the above structure, when in use, first place the metal casting on the top of the workbench 1, and align one side of it with the limit plate 11, and then clamp and fix the other three sides of the metal casting through the clamping assembly to prevent it from moving during the grinding process and affecting the grinding effect. Then, the four hydraulic cylinders 2 drive the U-shaped plate 3 and the grinding roller 10 to move downward until the grinding roller 10 contacts the top of the metal casting, and then start the grinding motor 9 to drive the grinding roller 10 to rotate, and grind the top of the metal casting, which improves the grinding efficiency and is easy to adapt to metal castings of different thicknesses, and is more practical.

[0025] like Figure 3 As shown, the sliding assembly includes two screw rods 5, and the relative inner walls of the U-shaped plate 3 are provided with sliding grooves. A transmission hole is provided in the U-shaped plate 3. One ends of the two screw rods 5 are rotatably installed on the side inner walls of the transmission hole, and the other ends of the two screw rods 5 are respectively rotatably installed on the side inner walls of the two sliding grooves. The two screw rods 5 are connected by a transmission unit, and the two sliders 4 are respectively threadedly installed on the two screw rods 5. The advantage of such an arrangement is that the function of driving the two sliders 4 to move synchronously can be realized through the arrangement of the two screw rods 5.

[0026] Specifically, when it is necessary to drive the grinding roller 10 to move horizontally to grind the top of the metal casting, the two screws 5 are rotated, and then the two sliders 4 and the grinding roller 10 are driven to move horizontally synchronously through the action of the threads, thereby achieving a uniform grinding function.

[0027] like Figure 3 As shown, the transmission unit includes two sprockets 6, which are fixedly sleeved on two screw rods 5 respectively, and chains 7 are installed on the two sprockets 6 in meshing with each other. A mobile motor 8 is fixedly installed on the side of the U-shaped plate 3, and the output shaft of the mobile motor 8 is connected to the end of one of the screw rods 5. The advantage of this arrangement is that the two screw rods 5 can be driven to realize the synchronous rotation function through the arrangement of the two sprockets 6 and the chain 7.

[0028] Specifically, when it is necessary to drive the grinding roller 10 to achieve uniform grinding, one of the screws 5 is driven to rotate by starting the mobile motor 8, and then the other screw 5 is driven to achieve synchronous rotation under the meshing action of the two sprockets 6 and the chain 7, thereby effectively avoiding the grinding roller 10 from getting stuck during movement.

[0029] like Figure 5 As shown, the moving assembly includes a screw rod 13, both ends of which are rotatably mounted on the opposite inner walls of the sliding hole, a clamping motor 14 is fixedly mounted on the side of the workbench 1, the output shaft of the clamping motor 14 is connected to the end of the screw rod 13, and the L-shaped slide plate 12 is threadedly mounted on the screw rod 13. The advantage of this arrangement is that through the arrangement of the screw rod 13, the L-shaped slide plate 12, the fixed plate 15, and the clamping assembly can be driven to move horizontally synchronously.

[0030] Specifically, when the metal casting needs to be clamped and fixed, the clamping motor 14 is started to drive the L-shaped slide plate 12 to move horizontally, thereby driving the fixing plate 15 and the clamping assembly to move horizontally synchronously, and the metal casting is fixed by the clamping assembly during the horizontal movement.

[0031] like Figure 5 As shown, the clamping assembly includes an extrusion plate 17, a through hole is opened on the side of the fixed plate 15, a sliding shaft 16 is slidably installed in the through hole, the extrusion plate 17 is fixedly installed at the end of the sliding shaft 16, a compression unit is arranged on the side of the extrusion plate 17, two mounting holes are opened on the side of the extrusion plate 17, a clamping plate 19 is slidably installed in both mounting holes through a limiting unit, connecting rods 21 are rotatably installed on the sides of the two clamping plates 19, and the other ends of the two connecting rods 21 are rotatably installed on the sides of the fixed plate 15. The advantage of such a configuration is that the horizontal movement of the fixed plate 15 can drive the extrusion plate 17 and the two clamping plates 19 to achieve the fixing function of the three sides of the metal casting.

[0032] Specifically, when the L-shaped slider 12 drives the fixed plate 15 to move horizontally, the fixed plate 15 drives the sliding shaft 16, the extrusion plate 17, and the two clamping plates 19 to move synchronously. When the extrusion plate 17 contacts the side of the metal casting, the extrusion effect of the metal casting stops the movement. At this time, the fixed plate 15 can continue to move under the action of the sliding shaft 16, thereby driving the two clamping plates 19 to move toward each other through the two connecting rods 21, thereby clamping and fixing the two sides of the metal casting.

[0033] like Figure 5As shown, the compression unit includes a compression spring 18, which is sleeved on the sliding shaft 16, one end of the compression spring 18 is fixedly installed on the side of the extrusion plate 17, and the other end of the compression spring 18 is fixedly installed on the side of the fixed plate 15. The advantage of this arrangement is that, through the arrangement of the compression spring 18, after the extrusion effect on the extrusion plate 17 is released, its elastic effect can drive it to achieve a reset function.

[0034] Specifically, when the clamping and fixing of the metal casting is released, the L-shaped slide plate 12 drives the fixing plate 15 to reset. At this time, the squeezing plate 17 can be kept in a stationary state under the elastic action of the compression spring 18, thereby realizing the reset function.

[0035] like Figure 5 As shown, the limit unit includes a limit rod 20, both ends of which are fixedly mounted on the opposite inner walls of the mounting hole, and a limit hole is opened on the side of the clamp 19, and the limit rod 20 is slidably mounted in the limit hole. The advantage of such an arrangement is that the limit function of the clamp 19 can be realized through the arrangement of the limit rod 20.

[0036] Specifically, by arranging the limiting rod 20 in the mounting hole, a guiding and limiting function can be provided for the sliding of the clamping plate 19, thereby preventing the clamping plate 19 from deflecting or falling off when sliding, and improving the stability during clamping.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
