Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of single crystal silicon processing, in particular to a grinding wheel dressing device for a silicon rod grinder. Background Art
[0002] The machining of single crystal square silicon rods usually uses horizontal or vertical grinders. The basic principle of grinding is that the grinding wheel rotates at high speed driven by a motor to grind the silicon rod. Through multiple grindings, the semi-finished square silicon rod is processed into a finished square silicon rod with a specific size and a specific roughness. The grinding wheel will wear and passivate during the long-term grinding process, resulting in abnormal size and surface quality of the finished square silicon rod. Therefore, the grinding wheel needs to be dressed within a certain period. If the grinding wheel is dressed by hand-held grinding stone, it will cause safety accidents during the grinding wheel dressing process and irregular grinding wheel after correction.

[0021] The beneficial effects of the present utility model are:
[0022] (1) The utility model has a mounting slot on the mounting seat for placing the oilstone and the top block.

[0032] To make the content of the present utility model easier to be clearly understood, the following further detailed description of the present utility model is made according to the detailed implementation manner and in combination with the drawings.
[0033] Figure 1 The structural schematic diagram of the silicon rod grinder grinding wheel dressing device provided by the embodiment of the present application. The device includes a mounting base 1, a mounting slot 2, an oilstone 3, a top block 4 and a tightening bolt 5. Among them, both the oilstone 3 and the top block 4 are located in the mounting slot 2. By applying pressure to the top block 4 through the tightening bolt 5, the oilstone 3 can be tightened in the mounting slot 2, realizing the fixation of the oilstone 3, and thus facilitating the dressing of the grinding wheel.
[0034] Specifically, referring to Figure 1 , the mounting base 1 is in a "C" shape, including a main body part 8 and two side plates 9 located on both sides of the main body part 8. These two side plates 9 are parallel to each other. Mounting slots 2 for accommodating the oilstone 3 and the top block 4 are provided on the outer sides of these two side plates 9.
[0035] Referring to Figure 2 , the mounting slot 2 includes a first slot 6 and a second slot 7. The second slot 7 is located behind the first slot 6. The oilstone 3 is located in the first slot 6, and when one end of the oilstone 3 abuts against the end of the first slot 6 away from the tightening bolt 5, the other end of the oilstone 3 extends into the second slot 7, referring to Figure 3 , that is, the length of the oilstone 3 is greater than the length of the first slot 6. Referring to Figure 3 , the top block 4 is located in the second slot 7 and is on the left side of the oilstone 3. The width of the top block 4 is smaller than the width of the second slot 7, so that the top block 4 can move left and right when located in the second slot 7. The right end of the tightening bolt 5 extends into the second slot 7, and the axis of the tightening bolt 5 is perpendicular to the butt joint direction of the oilstone 3 and the top block 4. The top block 4 is located between the oilstone 3 and the tightening bolt. By rotating the tightening bolt 5, the end of the tightening bolt 5 located in the second slot 7 can be moved to the right, and thus pressure can be applied to the top block 4 to tighten the oilstone 3 in the mounting slot 2, realizing the fixation of the oilstone 3.
[0036] The depth of the second slot 7 is greater than that of the first slot 6. First, the depth of the first slot 6 is small, which not only reduces the depth of the oilstone 3 in the first slot 6, thereby increasing the usable thickness of the oilstone 3, so that the oilstone 3 can be fully used, but also enables better contact between the top block 4 and the oilstone 3. Secondly, the depth of the second slot 7 is large, which not only ensures that the top block 4 has enough thickness to contact with the oilstone 3 and the jacking bolt 5, but also facilitates the installation and removal of the oilstone 3.
[0037] In this embodiment, the thickness of the top block 4 is less than or equal to the depth of the second slot 7. In this way, the end surface of the top block 4 will not exceed the side surface of the side plate 9, thereby not affecting the normal use of the oilstone 3.
[0038] It should be noted that the axis of the jacking bolt 5 is located at one-half of the depth of the second clamping groove 7. In this way, the jacking bolt 5 can better apply pressure to the top block 4. At the same time, the hexagon socket screw head at the end of the jacking bolt 5 will not exceed the outer side of the side plate 9, so as not to affect the normal use of the oilstone 3.
[0039] In this embodiment, two tightening bolts 5 are threadedly penetrated at both ends of the outer side surface of the main body 8 .
[0040] See also Figure 1 On the mounting seat 1, the main body 8 and the two side plates 9 are all threaded with a mounting bolt 10, and the axis of the mounting bolt 10 is parallel to the thickness direction of the mounting seat 1, that is, the mounting bolt 10 penetrates the mounting seat 1 along the thickness direction of the mounting seat 1. The mounting seat 1 is detachably mounted on the base 11 by the mounting bolt 10, see Figure 4 .
[0041] Preferably, the three mounting bolts 10 are arranged in a triangle, that is, the three mounting bolts 10 are respectively located at three vertices of the triangle, so that the mounting base 1 is stably mounted on the base 11 .
[0042] The base 11 is located between two grinding wheels 14. A detection device is provided below each grinding wheel 14. Figure 5 The detection device includes a probe box 12. The probe 13 in the probe box 12 is retracted in a direction perpendicular to the side plate 9, so that the ejector pin can contact the oilstone 3 after extending outward for a certain distance, thereby detecting the specific position of the oilstone 3. The grinding wheel 14 is driven by the grinding wheel driving device and can move in the vertical and horizontal directions to adjust the position of the grinding wheel. The grinding wheel driving device is electrically connected to the controller. After receiving the position of the oilstone 3 detected by the detection device, the controller controls the operation of the grinding wheel driving device according to the position of the oilstone 3, so that the grinding wheel 14 moves to the wheel surface and contacts the adjacent oilstone 3, and then the grinding wheel can be dressed by driving the grinding wheel to rotate.
[0043] Therefore, the technical solution of the present application provides a mounting slot 2 on the mounting seat 1 for placing the oilstone 3 and the top block 4. The oilstone 3 is tightened in the mounting slot 2 through the cooperation of the tightening bolt 5 and the top block 4, thereby achieving stable clamping of the oilstone 3, avoiding safety accidents during the grinding wheel dressing process and irregularities of the grinding wheel after correction.
[0044] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
