[0002] In actual production, due to limitations such as space and cost, crystal factories are usually only equipped with cross-cutting equipment.

If this type of equipment is to be used to longitudinally cut crystal segments in order to observe the longitudinal growth of the crystal rods, new crystal segment clamps must be designed to adapt to the cutting direction of the cutting structure.

[0034] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] In the description of the embodiments of this utility model, it should be understood that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0036] To clearly illustrate this technical solution, it is first clarified that: crystal rods produced by crystal factories generally have a tapered end and a cylindrical body. In this field, the process of cutting along the radial direction of the crystal rod (or crystal segment) is called transverse cutting, and the process of cutting along the axial direction of the crystal rod (or crystal segment, crystal rod cone) is called longitudinal cutting. The longitudinal cutting direction is parallel to the axis of the crystal rod (or crystal segment, crystal rod cone), meaning the longitudinal cutting may or may not pass through the axis of the crystal rod (or crystal segment, crystal rod cone). Furthermore, it is clarified that the longitudinally cut crystal segment 3 mentioned below includes both a crystal segment and a crystal rod cone, which originate from single-crystal crystal rods or other crystal rods grown by the Czochralski method (or zone melting method). The crystal segment and the crystal rod cone are transversely cut products of the crystal rod, and the axial end faces of the crystal rod cone are two parallel planes, i.e., the crystal rod cone is frustum-shaped or similar to a frustum.

[0037] This utility model provides a crystal segment longitudinal cutting fixture and a cutting device equipped with such a crystal segment longitudinal cutting fixture. The crystal segment longitudinal cutting fixture connects the crystal segment 3 to be longitudinally cut and the jaws 4 on the cutting device to solve the problem that the crystal rod transverse cutting device cannot meet the needs of temporary longitudinal cutting of crystal segments or crystal rod cones.

[0038] To concisely illustrate this technical solution, the following will use a cutting device equipped with a segment longitudinal cutting fixture to comprehensively introduce the segment longitudinal cutting fixture and cutting device provided by this utility model.

[0039] The aforementioned cutting equipment equipped with a segment longitudinal cutting fixture also includes jaws 4 and cutting lines 5. Similar to existing crystal rod cross-cutting equipment (e.g., crystal rod cutting equipment), the jaws 4 can clamp crystal rods with horizontal axes, and the cutting lines 5 can cut along the radial direction of the crystal rod held by the jaws 4; see attached figure. Figure 1 The crystal segment longitudinal cutting fixture includes a clamping assembly 1 and a mounting component 2. The mounting component 2 connects the clamping assembly 1 and the jaws 4. The clamping assembly 1 clamps the crystal segment 3 to be cut so that the axial direction of the crystal segment 3 to be cut is consistent with the cutting direction of the cutting line 5. The clamping assembly 1 includes a first clamping plate 11 and a second clamping plate 12 arranged parallel to and spaced apart along the cutting direction of the cutting line 5. The first clamping plate 11 and the second clamping plate 12 respectively contact the two ends of the crystal segment 3 to be cut, so that the axial direction of the crystal segment 3 to be cut is consistent with the cutting direction of the cutting line 5.

[0040] In the above technical solution, when the jaws 4 clamp the mounting component 2, the crystal segment 3 to be cut, held by the clamping assembly 1, is fixed on the cutting equipment. When the first clamping plate 11 and the second clamping plate 12 in the clamping assembly 1 contact the two ends of the crystal segment 3 to be cut, the axis of the crystal segment 3 to be cut is perpendicular to the surface of the first clamping plate 11 (or the second clamping plate 12). When connecting the mounting component 2 and the jaws 4, as long as the surface of the first clamping plate 11 is perpendicular to the cutting direction of the cutting line 5, the axial direction of the crystal segment 3 to be cut is consistent with the cutting direction of the cutting line 5, thus achieving the purpose of longitudinally cutting the crystal segment 3. This allows the crystal factory to observe the longitudinal growth front of the crystal segment, analyze the longitudinal stress distribution of the crystal segment, and thereby identify the differences between crystal segments and optimize or verify the optimized thermal field data. It should be noted that the first clamping plate 11 and the second clamping plate 12 play a clamping role. In addition to the clamping plate structure disclosed in this embodiment, other clamping components with different structures can also play a clamping role.

[0041] In addition to the first clamping plate 11 and the second clamping plate 12, the clamping assembly in the crystal segment longitudinal cutting fixture provided in this embodiment also includes an adjusting member 13. The first clamping plate 11 and the second clamping plate 12 are both connected to the adjusting member 13. At least one of the first clamping plate 11 and the second clamping plate 12 is movably connected to the adjusting member 13 to adjust the distance between the first clamping plate 11 and the second clamping plate 12. The mounting member 2 is connected to the adjusting member 13 and is disposed between the first clamping plate 11 and the second clamping plate 12.

[0042] When the clamping assembly 1 is used to clamp the crystal segment (or crystal rod cone), the distance between the first clamping plate 11 and the second clamping plate 12 is first increased by the adjusting member 13, and the crystal segment (or crystal rod cone) is placed between the first clamping plate 11 and the second clamping plate 12, so that the facing surfaces of the first clamping plate 11 and the second clamping plate 12 correspond to the two end faces of the crystal segment (or crystal rod cone) respectively. Then, the distance between the first clamping plate 11 and the second clamping plate 12 is reduced by the adjusting member 13, so that the facing surfaces of the first clamping plate 11 and the second clamping plate 12 are pressed against the two end faces of the crystal segment (or crystal rod cone) respectively, so that the crystal segment (or crystal rod cone) is clamped by the first clamping plate 11 and the second clamping plate 12 in a direction that is perpendicular to the plate surface of the first clamping plate 11 (or the second clamping plate 12) with its own axis perpendicular to the plate surface, so that when the mounting part 2 is fixed by the claw 4, the axial direction of the crystal segment (or crystal rod cone) is parallel to the cutting direction of the cutting line 5.

[0043] The adjusting member 13 for adjusting the distance between the first clamping plate 11 and the second clamping plate 12 can have various configuration schemes. This embodiment only provides some feasible configuration schemes by way of example, but the following examples are not intended to limit the scope of protection of this utility model. For example, the adjusting member 13 may include a first adjusting rod 131 and a first nut 132. At least one of the first clamping plate 11 and the second clamping plate 12 is provided with a first mounting hole 15. At least one side of the first mounting hole 15 is provided with a first nut 132. The first adjusting rod 131 passes through the first mounting hole 15, and the first nut 132 is sleeved on the first adjusting rod 131 and threaded to it. In use, the first nut 132 is rotated away from the first clamping plate 11 (or the second clamping plate 12) to loosen the first clamping plate 11 (or the second clamping plate 12), so that the first clamping plate 11 (or the second clamping plate 12) can move along the axial direction of the first adjusting rod 131, thereby changing the distance between the first clamping plate 11 and the second clamping plate 12. When the distance between the first clamping plate 11 and the second clamping plate 12 is properly adjusted, the first nut 132 is rotated towards the first clamping plate 11 (or the second clamping plate 12) to fix the relative position of the first clamping plate 11 (or the second clamping plate 12) and the first adjusting rod 131. In this way, the clamping and fixing of crystal segments (or crystal rod cones) with different axial dimensions can be achieved.

[0044] The number of the first adjusting rod 131 and the first nut 132 can be configured according to actual needs, and no more specific limitation is made here. For example, in order to ensure the connection stability between the first clamping plate 11 and the second clamping plate 12 and the clamping stability of the crystal segment (or crystal rod cone), multiple sets of the first adjusting rod 131 can be arranged in parallel, and one set of the first nut 132 can be arranged on each side of the first mounting hole 15. The two sets of first nuts 132 can achieve bidirectional clamping of the first clamping plate 11 (or the second clamping plate 12) and ensure the connection stability between the first clamping plate 11 (or the second clamping plate 12) and the first adjusting rod 131.

[0045] In actual use, the first clamping plate 11 and the second clamping plate 12 should be at different heights in the same vertical direction. Taking the first clamping plate 11 on top and the second clamping plate 12 on the bottom as an example, the first adjusting rod 131 can be fixedly connected to the first clamping plate 11 at its top end and movably connected to the second clamping plate 12 at its bottom end, or it can be movably connected to the first clamping plate 11 at its top end and fixedly connected to the second clamping plate 12 at its bottom end, or it can be movably connected to the first clamping plate 11 at its top end and movably connected to the second clamping plate 12 at its bottom end. The implementer can select from the above configuration schemes as needed to determine the position and number of the first mounting holes 15.

[0046] The aforementioned mounting component 2 can be fixedly connected to the adjusting component 13 or integrally formed, or it can be movably connected to the adjusting component 13. The connection scheme can be selected by the implementer as needed. As an example, this embodiment introduces some preferred configuration schemes: refer to the attached... Figure 2-4 The mounting component 2 is located between the first clamping plate 11 and the second clamping plate 12. The adjusting component 13 is equipped with a second adjusting rod 133 and a second nut 134. At least one of the first clamping plate 11 and the second clamping plate 12 is movably connected to the second adjusting rod 133. The mounting component 2 has a second mounting hole 221, and at least one side of the second mounting hole 221 has a second nut 134. The second adjusting rod 133 passes through the second mounting hole 221, and the second nut 134 is sleeved on the second adjusting rod 133 and threaded to it. In use, the second nut 134 is rotated away from the mounting component 2 to loosen the mounting component 2, allowing the mounting component 2 to move axially along the second adjusting rod 133, thus changing the distance between the mounting component 2 and the first clamping plate 11 (or the second clamping plate 12). When the distance between the mounting component 2 and the first clamping plate 11 (or the second clamping plate 12) is properly adjusted, the second nut 134 is rotated towards the mounting component 2 to fix the relative position of the mounting component 2 and the second adjusting rod 133.

[0047] The adjustable mounting component 2 allows for adjustment of the overall center of gravity of the crystal segment longitudinal cutting fixture and the crystal segment 3 it holds, thereby improving the connection stability of the jaws 4, the crystal segment longitudinal cutting fixture, and the crystal segment 3 to be longitudinally cut. This prevents the crystal segment 3 from tilting during longitudinal cutting due to uneven force or unstable center of gravity, thus ensuring the accuracy of the cutting direction and the cutting surface.

[0048] As mentioned above, there are multiple configuration options for the second adjusting rod 133 and the mounting component 2. Due to the presence of the first adjusting rod 131 and the first nut 132, the second adjusting rod 133 does not need to undertake the task of connecting the first clamping plate 11 and the second clamping plate 12 and adjusting their distance. Of course, the number of first adjusting rods 131 can also be reduced, and the second adjusting rod 133 can be used to jointly undertake the task of connecting the first clamping plate 11 and the second clamping plate 12 and adjusting their distance, so as to simplify the structural configuration of the crystal segment longitudinal cutting fixture and reduce the workpiece manufacturing cost.

[0049] Regardless of the configuration scheme mentioned above, it should be ensured that: at least one set of second nuts 134 is provided below the mounting part 2 to achieve the function of supporting and positioning it from below the mounting part 2.

[0050] Regardless of the configuration scheme described above, the end of the second adjusting rod 133 used to connect the first clamping plate 11 or the second clamping plate 12 can be configured to be fixed or movable. When the latter is selected, a third nut 135 should also be configured in the adjusting member 13, and a third mounting hole 16 should be configured on at least one of the first clamping plate 11 and the second clamping plate 12. At least one side of the third mounting hole 16 is provided with a third nut 135. The second adjusting rod 133 passes through the third mounting hole 16, and the third nut 135 is sleeved on the second adjusting rod 133 and threaded to it, thereby realizing that: not only can the distance between the mounting member 2 and the first clamping plate 11 (or the second clamping plate 12) be changed by adjusting the second nut 134, but also the distance between the mounting member 2 and the first clamping plate 11 (or the second clamping plate 12) can be changed by adjusting the third nut 135. At the same time, in this configuration scheme, the distance between the first clamping plate 11 and the second clamping plate 12 can also be changed by adjusting the third nut 135.

[0051] In some preferred embodiments, the second adjusting rod 133 is configured to include a first rod segment 1331 and a second rod segment 1332 coaxially spaced apart. The proximal ends of the first rod segment 1331 and the second rod segment 1332 are respectively inserted into the second mounting hole 221. The disjoint ends of the first rod segment 1331 and the second rod segment 1332 are respectively connected to the first clamping plate 11 and the second clamping plate 12, and at least one of them is movable, so as to further improve the adjustment flexibility of the longitudinal cutting fixture of this crystal segment. In this embodiment, the second adjusting rod 133 including the first rod segment 1331 and the second rod segment 1332 facilitates the installation and disassembly of the mounting component 2. When installing or removing the mounting component 2, only one of the first rod segment 1331 and the second rod segment 1332 needs to be moved.

[0052] Based on this, the connection method between the second adjusting rod 133 and the mounting part 2 can be further optimized. The second mounting hole 221 can be set as a threaded hole so that the second adjusting rod 133 is threaded to it, thereby further improving the connection stability between the second adjusting rod 133 and the mounting part 2.

[0053] In addition to the above, the first mounting hole 15 or the third mounting hole 16 can also be configured as a waist-shaped hole, with the length direction of the waist-shaped hole being consistent with the length direction of the first clamping plate 11. By moving the first adjusting rod 131 or the second adjusting rod 133 along the length direction of the waist-shaped hole, the clamping and fixing requirements for crystal segments (or crystal rod cones) with different radial dimensions or the clamping and fixing requirements for crystal segments (or crystal rod cones) with different longitudinal cutting paths can be met.

[0054] When the radial dimension of the crystal segment (or crystal rod cone) is large, or when the longitudinal cutting path does not pass through the axis of the crystal segment (or crystal rod cone), the distance between the first adjusting rod 131 and the second adjusting rod 133 can be appropriately reduced, so that more space is reserved for accommodating and clamping the crystal segment (or crystal rod cone) between the first clamping plate 11 and the second clamping plate 12.

[0055] To improve the clamping stability of the crystal segment (or crystal rod cone), anti-slip pads 14 can be provided on the facing surfaces of the first clamping plate 11 and the second clamping plate 12, respectively. The anti-slip pads 14 are located on the outside of the first nut 132 and the third nut 135 to avoid affecting the locking effect of the first nut 132 and the third nut 135. As an example, the anti-slip pads 14 can be rubber pads with raised dots or textures.

[0056] The configuration of mounting component 2 in this technical solution can be refined according to actual needs. This embodiment exemplifies some preferred configurations: see attached... Figure 5 The mounting component 2 includes a first mounting section 21, a connecting section 22, and a second mounting section 23 connected in sequence. The first mounting section 21 and the second mounting section 23 are symmetrical about the connecting section 22. The opposite sides of the first mounting section 21 and the second mounting section 23 are respectively connected to the jaws 4 in the cutting equipment. The connecting section 22 is connected to the clamping assembly 1, and the connecting section 22 is at least partially located between the first clamping plate 11 and the second clamping plate 12. The height of the connecting section 22 is less than the height of the first mounting section 21. Using a connecting section 22 with a smaller middle height can reduce space occupation, workpiece weight and workpiece material cost. In addition, the top and bottom surfaces of the connecting section 22 can be configured as flat surfaces, and the connection stability can be improved by increasing the contact area between the second nut 134 and the connecting section 22.

[0057] In practical implementation, the outer contours of the first mounting section 21 and the second mounting section 23 can be adaptively adjusted according to the configuration of the chuck 4 in the cutting equipment. For example, the first mounting section 21 and the second mounting section 23 can be plate-shaped structures parallel to the first clamping plate 11, or they can be designed with reference to the shape of the crystal rod held during normal cutting by the crystal rod cross-cutting equipment, as shown in the attached figure. Figure 5 As shown: the first arc-shaped wall 211 and the second arc-shaped wall 231 are located on opposite sides of the first mounting section 21 and the second mounting section 23, respectively. The axial directions of the first arc-shaped wall 211 and the second arc-shaped wall 231 are perpendicular to the axial direction of the crystal segment 3 to be cut held by the clamping assembly 1, so as to simulate the arc-shaped contour of the outer wall of the crystal rod, and are stably clamped by the chuck 4 in the cutting equipment.

[0058] When installing the longitudinal cutting fixture of this crystal segment onto the jaw 4, it is necessary to adjust the connection angle between the mounting part 2 and the jaw 4 to ensure that the surfaces of the first clamping plate 11 and the second clamping plate 12 are perpendicular to the cutting direction of the cutting line 5. To adjust the connection angle between the mounting part 2 and the jaw 4, simply rotate the mounting part 2. When observing whether the surfaces of the first clamping plate 11 and the second clamping plate 12 are perpendicular to the cutting direction of the cutting line 5, visual inspection can be used, or some portable measuring instruments (such as a bubble level) can be used. Of course, since the first adjusting rod 131 and the second adjusting rod 133 are both perpendicular to the first clamping plate 11 and the second clamping plate 12, the bottom planes of the first adjusting rod 131 and the second adjusting rod 133 can be pressed against the top surface of the machine tool below the jaw 4 to accurately adjust the direction of the first clamping plate 11 and the second clamping plate 12.

[0059] Even better, several weight-reducing holes 24 can be provided on the mounting part 2 to reduce the weight of the workpiece. The weight-reducing holes are symmetrical about the connecting section 22 to avoid uneven weighting.

[0060] In the cutting equipment provided in this embodiment, apart from the above-mentioned longitudinal cutting jig for crystal segments, the rest of the structure can adopt the configuration of existing transverse cutting equipment for crystal rods, such as the configuration of the chuck 4 and cutting line 5 in existing crystal rod cutting equipment. The structural configuration scheme and structural linkage scheme can be directly obtained by those skilled in the art from the existing technology, and will not be described in detail here.

[0061] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0062] (1) The crystal segment longitudinal cutting fixture provided by this utility model can be applied to the crystal rod transverse cutting equipment. The clamping claws 4 and the clamping assembly 1 with perpendicular clamping directions of the crystal segments are connected by the mounting component 2 to achieve the purpose of temporarily longitudinally cutting crystal segments or crystal rod cones using the crystal rod transverse cutting equipment, and to ensure the clamping stability of the crystal segments or crystal rod cones and the accuracy of the cutting direction during the cutting process.

[0063] (2) The crystal segment longitudinal cutting fixture provided by this utility model has strong applicability: by adjusting the distance between the first clamping plate 11 and the second clamping plate 12, it can meet the clamping and fixing requirements of crystal segments (or crystal rod cones) with different axial dimensions; by adjusting the distance between the first adjusting rod 131 and the second adjusting rod 133, it can meet the clamping and fixing requirements of crystal segments (or crystal rod cones) with different radial dimensions, or meet the clamping and fixing requirements of crystal segments (or crystal rod cones) with different longitudinal cutting paths.

[0064] (3) The cutting device provided by this utility model has multiple uses: it can be used for temporary longitudinal cutting of crystal segments or crystal rod cones when the crystal segment longitudinal cutting clamp is connected to the chuck 4, and can be used for transverse cutting of crystal rods after the crystal segment longitudinal cutting clamp is removed.

[0065] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
