[0025] like Figure 1-4 As shown, the utility model provides a device for grinding the edge of a cast iron part, which includes a support seat 2 as a support base and a grinding mechanism 3 installed on a first base 21 for grinding the edge of the cast iron part 1. Specifically:
[0026] like Figure 1 As shown, the support base 2 includes a first base 21, a second base 22, a guide cylinder structure 23 and a threaded cylinder structure 24. The first base 21 is a solid plate structure, which is used to install the grinding mechanism 3 described below. The second base 22 is a frame-shaped structure and is provided with an opening to facilitate the taking and placing of the cast iron part 1. There are three guide cylinder structures 23 in total, including a guide light rod fixedly connected to the first base 21 and a light rod sleeve fixedly connected to the second base 22 and movably sleeved with the guide light rod. The threaded cylinder structure 24 includes a threaded column fixedly connected to the first base 21 and a threaded cylinder barrel rotatably connected to the second base 22 and threadedly engaged with the threaded column. When the threaded cylinder barrel is rotated, the distance between the first base 21 and the second base 22 can be adjusted by threading it with the threaded column, so as to Figure 4 The shown figure is adapted to cast iron parts 1 of different heights.
[0027] like Figure 2-3As shown, the grinding mechanism 3 includes a motor 37 fixedly connected to the first base 21, a connecting plate 36 fixedly connected to the output shaft of the motor 37, a pair of connecting shafts 35 fixedly connected to the outer annular surface of the connecting plate 36, a connecting ring 34 fixedly connected to one end of the two connecting shafts 35, a threaded sleeve 33 with two ends respectively connected to the corresponding connecting ring 34 for rotation, a pair of connecting arms 32 respectively screwed with the two ends of the threaded sleeve 33, and a grinding piece 31 fixed to the top of the two connecting arms 32. The grinding piece 31 is in a right angle shape, and the right angle inner angle surface is provided with bristles 311. The inner annular surface of the connecting ring 34 is fixedly connected to a guide slider 341, and the outer annular surface of the connecting arm 32 is provided with a guide slide groove 321 for the guide slider 341 to slide. The grinding mechanism 3 also includes a support slide bar 38 fixedly connected to the connecting shaft 35 at the top, and a slide rail 211 for the bottom end of the support slide bar 38 to rotate horizontally is fixedly connected to the surface of the first base 21. The output shaft of the motor 37 drives the connecting plate 36 to rotate, and then drives the grinding piece 31 to rotate horizontally through the connecting shaft 35 and the connecting ring 34, and the rotation generates friction between the bristles 311 and the edge of the cast iron piece 1 to achieve grinding. In addition, when the threaded sleeve 33 is rotated, the threaded engagement between the threaded sleeve 33 and the two connecting arms 32 can drive the two connecting arms 32 to move in the opposite direction to adjust the distance between the two grinding pieces 31, so that the bristles 311 can be close to the edges of the cast iron pieces 1 with different diameters.
[0028] The working principle of this embodiment is as follows: most cast iron parts have arc edges, so the device of this embodiment is described by grinding the arc edges as an example, wherein the shape and size of the cast iron part 1 are only for illustration and are not the only choice;
[0029] Specifically, there are two grinding methods for the cast iron part 1. One is that when the cast iron part 1 is a light workpiece, since it can be directly held in the hand, it can be referred to Figure 1 As shown, the first base 21 is placed on a workbench, and the cast iron part 1 is held so that the edge of the cast iron part 1 is located between the two grinding parts 31. When the threaded sleeve 33 is rotated, the threaded engagement between the threaded sleeve 33 and the two connecting arms 32 drives the two connecting arms 32 to move in opposite directions to adjust the distance between the two grinding parts 31, so that the bristles 311 are close to the edge of the cast iron part 1. Then the output shaft of the motor 37 drives the connecting disk 36 to rotate, and then drives the grinding part 31 to rotate horizontally through the connecting shaft 35 and the connecting ring 34, and the rotation causes the bristles 311 to generate friction with the edge of the cast iron part 1 to achieve grinding;
[0030] When the iron casting 1 is a heavy workpiece, refer to Figure 4 , place the second base 22 on the workbench, and also place the cast iron part 1 on the workbench, and fix it by hand or by using a clamp, etc., which is selected according to the actual workpiece. Then, grind it in the same way as above.
[0031] In summary, through the design of the grinding mechanism 3, the two grinding pieces 31 can be used to quickly and accurately grind the edge of the cast iron part 1, and the spacing between the two grinding pieces 31 can be adjusted accordingly according to the edge diameter of the cast iron part 1, and the application range is wide; through the design of the support base 2 with the first base 21 and the second base 22, the direction of the entire device can be adjusted to grind the edge of the cast iron part 1 from the top or bottom respectively, so as to be suitable for both light workpieces and heavy workpieces.
[0032] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
