Description

Technical Field

[0001] The utility model relates to the technical field of diamond wire guide wheels, in particular to a quick-change diamond wire guide wheel seat structure and a diamond wire slicer. Background Art

[0002] 1. Overview of existing technology:

[0003] In current industry practice, two common designs for diamond wire guide wheels in silicon wafer slicers are used: a large wheel secured with three screws, and a smaller wheel secured with a single screw. In other words, these guide wheels typically rely on screw connections, and replacing them requires the following steps: first, remove the old wheel; then, install the new one. This process must be performed at the end of each shift.

[0004] 2. Limitations and problems of existing technologies:

[0005] In the prior art, the guide wheel and the guide wheel seat are connected by screws. This connection method brings significant inconvenience during actual operation. The process of removing and fixing the screws is time-consuming and cumbersome, especially under the continuity requirement of the slicing operation, which leads to a long time for replacing the guide wheel, seriously affecting production efficiency. What is more serious is that when the screws are worn (such as slipping) or rusted due to long-term use, the entire guide wheel seat is often difficult to repair and can only be discarded, thereby increasing the cost burden. In addition, additional specific tools are required when replacing the guide wheel, which further increases the complexity and inconvenience of on-site management and maintenance. Utility Model Content

[0017] When the locking handle is in a vertical or tilted position, the eccentric cam portion is disengaged from the gasket, the elastic member recovers its elastic deformation, the fixation between the guide wheel and the guide wheel seat is cancelled, and the guide wheel can be removed from the guide wheel seat.

[0018] Furthermore, the elastic member is a spring.

[0019] Furthermore, a gourd-shaped hole is formed on the guide wheel, and the gourd-shaped hole includes a large hole and a small hole that are connected to each other. The size of the small hole is smaller than the size of the gasket and can form a blocking effect on the gasket. The outer size of the locking handle in the vertical state and the outer diameter of the gasket are both smaller than the size of the large hole and can be inserted into the large hole.

[0020] The quick-locking mechanism is assembled and fixed in the small hole, and when the fixation between the guide wheel and the guide wheel seat is cancelled, the quick-locking mechanism can be removed from the large hole.

[0021] Furthermore, three threaded holes are evenly provided on the guide wheel seat along its central axis, and three gourd-shaped holes are evenly provided on the guide wheel. The gourd-shaped holes are arranged in one-to-one correspondence with the threaded holes, and each gourd-shaped hole is provided with one of the quick locking mechanisms.

[0022] Furthermore, an open groove is formed at the end of the eccentric cam portion, and the end of the threaded shaft is located in the open groove and can freely rotate around the rotating shaft in the open groove.

[0023] Furthermore, the rotating shaft adopts a pin shaft, and the free end of the pin shaft is also equipped with a cotter pin for limiting position.

[0024] Furthermore, the eccentric cam portion is provided with an axial hole in the transverse direction, the axis of the axial hole is perpendicular to the axis of the threaded shaft, and the pin is assembled in the axial hole and passes through the open slot.

[0025] Furthermore, the small hole is an arc-shaped hole, the large hole is a circular hole, the width of the arc-shaped hole is smaller than the outer diameter of the gasket, and the width of the arc-shaped hole is not smaller than the outer diameter of the spring.

[0026] A diamond wire slicing machine comprises the quick-change diamond wire guide wheel seat structure.

[0049] Example 1

[0050] Reference Figures 1-6 This embodiment provides a quick-change diamond wire guide wheel seat structure, including:

[0051] The guide wheel seat 2 is provided with at least one threaded hole;

[0052] The guide wheel 1 is detachably mounted on the guide wheel seat 2;

[0053] The quick-locking mechanism 3 is used to quickly assemble the guide wheel 1 on the guide wheel seat 2.

[0054] Specifically, the quick lock mechanism 3 includes a threaded shaft 301, an elastic member, a locking handle 303, a rotating shaft 304 and a gasket 305;

[0055] One end of the threaded shaft 301 has an outer wall with external threads that mate with the threaded hole in the guide wheel seat 2. The threaded shaft 301 is screwed into the threaded hole in the guide wheel seat 2 to achieve a threaded connection. The elastic member can be a spring 302, preferably a compression spring. The spring 302 and the gasket 305 are respectively sleeved on the threaded shaft 301. The elastic member and the gasket 305 are located between the guide wheel seat 2 and the locking handle 303, and the elastic member is located between the gasket 305 and the locking handle 303. The inner diameter of the gasket 305 is smaller than the outer diameter of the elastic member.

[0056] The locking handle 303 includes a hand-operated portion 3031 and an eccentric cam portion 3032 connected to each other. The eccentric cam portion 3032 is rotatably connected to the other end of the threaded shaft 301 via the rotating shaft 304. The locking handle 303 can adjust the relative position between the gasket 305 and the guide wheel 1 by rotating.

[0057] When the locking handle 303 is in a horizontal position, the hand pull portion 3031 is engaged with the surface of the guide wheel 1, that is, the hand pull portion 3031 is in contact with the surface of the guide wheel 1, and the eccentric cam portion 3032 squeezes the gasket 305. At the same time, the gasket 305 is in contact with the guide wheel 1 and applies pressure, the elastic member is compressed, and the guide wheel 1 is fixed to the guide wheel seat 2.

[0058] When the locking handle 303 is in a vertical or inclined position, the eccentric cam portion 3032 disengages from the gasket 305, the elastic member restores its elastic deformation, the gasket 305 disengages from the guide wheel 1, the fixation between the guide wheel 1 and the guide wheel seat 2 is cancelled, and the guide wheel 1 can be removed from the guide wheel seat 2.

[0059] Specifically, a gourd-shaped hole 101 is provided on the guide wheel 1, and the gourd-shaped hole 101 includes a large hole 1011 and a small hole 1012 that are connected to each other. The size of the large hole 1011 is larger than the size of the small hole 1012, and the size of the small hole 1012 is smaller than the size of the gasket 305 and can form a blocking effect on the gasket 305. The outer size of the locking handle 303 in the vertical state and the outer diameter of the gasket 305 are both smaller than the size of the large hole 1011 and can be passed through the large hole 1011; through the gourd-shaped With this structural design of the hole 101, when the guide wheel 1 and the guide wheel seat 2 need to be assembled and fixed, the quick-locking mechanism 3 is inserted from the large hole 1011 and moved horizontally to the small hole 1012, and then the hand lever 3031 is pulled to complete the assembly and fixation of the quick-locking mechanism 3 in the small hole 1012; and when the fixation between the guide wheel 1 and the guide wheel seat 2 is cancelled, the quick-locking mechanism 3 can be moved horizontally in the opposite direction to the large hole 1011 and can be taken out from the large hole 1011, and the quick-locking mechanism 3 and the guide wheel seat 2 are separated and removed from the guide wheel 1 together.

[0060] In this embodiment, the guide wheel seat 2 has three threaded holes evenly spaced along its central axis, and the guide wheel 1 has three gourd-shaped holes 101 evenly spaced along its axis. The gourd-shaped holes 101 correspond to the threaded holes one by one, and each gourd-shaped hole 101 is provided with one of the quick-locking mechanisms 3. In other words, the guide wheel seat 2 and the guide wheel 1 are fixedly assembled together by the three quick-locking mechanisms 3.

[0061] An opening slot 3033 is provided at the middle position of the end of the eccentric cam portion 3032. The end of the threaded shaft 301 is located in the opening slot 3033 and can freely rotate around the rotating shaft 304 in the opening slot 3033. Figure 5 .

[0062] The rotating shaft 304 is a pin, and a cotter pin is mounted on the free end of the pin for limiting position. The eccentric cam portion 3032 has an axial hole formed in the transverse direction, the axis of which is perpendicular to the axis of the threaded shaft 301. The pin is assembled in the axial hole and passes through the open slot 3033. One end of the pin has a blocking portion, and the other end is mounted with a cotter pin to achieve axial limiting.

[0063] Note: If Figure 4 The small hole 1012 is an arc-shaped hole, and the large hole 1011 is a circular hole. The width of the arc-shaped hole is smaller than the outer diameter of the gasket 305 to form a blocking effect on the gasket 305, and the width of the arc-shaped hole is not smaller than the outer diameter of the spring 302 so that the spring 302 can be located in the small hole 1012, and the inner wall of the small hole 1012 can also limit the spring 302.

[0064] During normal use, when installing the guide wheel 1, the threaded shaft 301 of each quick lock mechanism 3 is locked on the three threaded holes of the guide wheel seat 2 through its own thread, and the guide wheel 1 is inserted into the locking handle 303 from the large hole 1011 of the gourd-shaped hole 101, and then moved horizontally to the small hole 1012 of the gourd-shaped hole 101, and the locking handle 303 is rotated to a horizontal state. At this time, the locking handle 303 presses the gasket 305 and the compression spring through the eccentric cam part 3032. When it is rotated into place, the eccentric cam part 3032 presses the gasket 305 on the guide wheel 1, achieving the effect of quick replacement and locking; when the guide wheel 1 needs to be removed, the locking handle 303 is pulled to the vertical position. At this time, the eccentric cam portion 3032 on the locking handle 303 is tightly separated from the gasket 305. After rotating it to the vertical direction, the spring 302 extends to bounce the gasket 305, and the gasket 305 is also separated from the guide wheel 1. Then, the quick locking mechanism 3 is moved horizontally in the opposite direction to the large hole 1011, and the guide wheel 1 can be separated from the guide wheel seat 2 through the large hole 1011, and the guide wheel 1 can be removed; the whole process does not require any tools and is easy to operate.
