Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] It should be noted that all components of the tooling described below are made of metal, enabling the tooling to be used even at high temperatures.

[0031] Example 1

[0032] refer to Figures 1-6 A crystal rod alignment and bonding fixture includes a base 1, a graphite plate A, a first top block 2, and a second top block 3;

[0033] The graphite plate A is placed horizontally on the base 1, and the graphite plate A is used to hold multiple crystal rods B to be bonded; in this embodiment, refer to Figure 1 The crystal rod B is cylindrical and includes four independent crystal rods B of the same size. When placed, the four crystal rods B are paired up, with the bottom surfaces of the pair of crystal rods B touching each other. The two pairs of crystal rods B are arranged side by side. It should be noted that this embodiment does not limit the shape and number of crystal rods B. The design of this embodiment is only a choice made for the convenience of explaining this solution.

[0034] The first top block 2 is disposed on the base 1; the second top block 3 is slidably connected to the base 1 and can move horizontally toward the first top block 2;

[0035] The first top block 2 is provided with a first abutting surface 201; the second top block 3 is provided with a second abutting surface 301; when the second top block 3 moves horizontally toward the first top block 2, the first abutting surface 201 and the second abutting surface 301 respectively contact the crystal rods B on the graphite plate A and make adjacent crystal rods B adhere together. In this embodiment, after the graphite plate A and the crystal rods B are adhered together, they can be bonded using sealing wax.

[0036] In this embodiment, graphite plate A is first placed horizontally on base 1 to ensure that crystal rod B remains stable after being placed on it. Then, multiple crystal rods B are bonded together by the first top block 2 and the second top block 3, thereby firmly bonding and connecting multiple crystal rods on graphite plate A. Then, graphite plate A is transferred to a cutting device for slicing, achieving the purpose of processing multiple crystal rods B in one clamping, thus improving production efficiency.

[0037] To accommodate the shape characteristics of crystal rod B, preferably, both the first abutting surface 201 and the second abutting surface 301 are inclined surfaces, and the first abutting surface 201 and the second abutting surface 301 form an inverted V shape. In this preferred configuration, when the second top block 3 moves horizontally towards the first top block 2, the second top block 3 pushes the crystal rod B closer to the first top block 2. After the crystal rods B come into contact with each other, the inclined first abutting surface 201 and the second abutting surface 301 exert a horizontal force on the crystal rod B towards the first top block 2, as well as a vertical force towards the graphite plate A, pressing the crystal rod B onto the graphite plate A. In actual work, the operator should also measure the straightness of the upper ends of the four crystal rods B by marking points to check whether the straightness of the four crystal rods B is consistent or close, thus avoiding a reduction in the processing accuracy of the slicing. Of course, any adjustments made by those skilled in the art to the first abutting surface 201 and the second abutting surface 301 for crystal rods of different shapes should also be within the scope of protection of this embodiment.

[0038] In this embodiment, the base 1 is provided with support plates 4; there are two support plates 4, which are respectively disposed at both ends of the base 1; the two ends of the graphite plate A are respectively placed on the two support plates 4. With the above design, the graphite plate A is placed horizontally, and both ends of the graphite plate A are supported, effectively reducing the risk of the graphite plate A breaking due to compression.

[0039] In this embodiment, specifically, the first top block 2 is provided with bolt holes; the first top block 2 is detachably connected to the base 1 through the bolt holes. When it is necessary to process crystal rods B of other sizes, the first top block 2 can be replaced to accommodate crystal rods B of different sizes, thereby increasing the applicability of this tooling.

[0040] In this embodiment, more specifically, it also includes a sliding seat 5; the base 1 is provided with a guide rail 101; the sliding seat 5 is slidably connected to the guide rail 101; and the second top block 3 is disposed on the sliding seat 5.

[0041] In this embodiment, the sliding seat 5 and the first top block 2 are arranged opposite to each other at both ends of the base 1. The sliding seat 5 can drive the second top block 3 away from or closer to the second top block 3.

[0042] More specifically, the sliding seat 5 includes a slider 51, a mounting block 52, and an adjusting bolt 53. The slider 51 is slidably connected to the guide rail 101; the mounting block 52 is disposed on the slider 51; the second top block 3 is slidably connected to the mounting block 52; the adjusting bolt 53 passes through the mounting block 52 and contacts one end of the second top block 3 and is used to push the second top block 3 to move horizontally toward the first top block 2.

[0043] Under the above design, the slider 51 drives the second top block 3 to move towards the first top block 2 for coarse adjustment, and then the adjusting bolt 53 pushes the second top block 3 towards the first top block 2 for fine adjustment, so that the degree of compression is adjustable, avoiding excessive compression of crystal rod B and graphite plate A, which may cause damage or prevent crystal rod B and graphite plate A from being firmly attached.

[0044] Preferably, the system further includes two limiting components 6, which are respectively disposed at both ends of the slider 51. Each limiting component 6 includes a guide block 61 and a locking bolt 62. The guide block 61 is disposed on the base 1. The guide block 61 has a guide groove 601 extending along the moving direction of the second top block 3. The locking bolt is threadedly connected to the slider 51, and one end of the locking bolt passes through the slider 51 and extends into the guide groove 601.

[0045] Under the above-mentioned preferred method, for repetitive bonding work, after the sliding has completed the coarse adjustment, the locking screw is rotated to press against the guide groove 601, thereby locking the slider 51 and preventing the slider 51 from moving horizontally. The operator then only needs to perform fine adjustment by rotating the adjusting bolt 53 to drive the second top block 3 to move horizontally.

[0046] In this embodiment, in order to support the graphite plate A more stably, the upper surfaces of the support plate 4, the guide block 61 and the guide rail 101 are located on the same plane.

[0047] refer to Figure 5 Further preferably, it also includes auxiliary components 7, wherein the support plate 4 and the guide block 61 are arranged adjacent to each other, and there is a gap between the support plate 4 and the guide block 61; there are two auxiliary components 7, which are respectively disposed at both ends of the slider 51, including a connecting block 71 and a pulley 72; one end of the connecting block 71 is disposed on the slider 51, and the other end of the connecting block 71 extends into the gap and connects with the pulley 72; the pulley 72 contacts the upper end surface of the base 1; the connecting block 71 is provided with a shovel base block 73 at the end where the pulley 72 is located; the lower end surface of the shovel base block 73 contacts the base 1; the shovel base block 73 is slidably connected in the gap.

[0048] In the further preferred embodiment described above, the connecting block 71 of the auxiliary component 7 plays a role in stabilizing the movement of the sliding seat 5, the pulley 72 on the connecting block 71 plays a role in assisting the sliding, and the shovel base block 73 on the connecting block 71 can effectively remove foreign objects in the movement path of the pulley 72 and prevent foreign objects from obstructing the movement of the pulley 72.

[0049] refer to Figure 6In this embodiment, preferably, the mounting block 52 has a cavity 501; the second top block 3 is slidably connected to the mounting block 52 through the cavity 501. More preferably, the mounting block 52 also has a slot 502 and a return spring 500; the slot 502 is arranged in the cavity 501, and there are two slots 502 symmetrically arranged on both sides of the second top block 3; one end of the return spring 500 is disposed in the slot 502, and the other end of the return spring 500 is connected to the second top block 3.

[0050] Under the above design, the second top block 3 can stably move forward or backward along the cavity 501 towards the first top block 2. When the adjusting bolt 53 is rotated clockwise to move the second top block 3 forward, the reset spring 500 in the slot 502 is compressed, which further stabilizes the movement of the second top block 3. When the adjusting bolt 53 is rotated counterclockwise, the adjusting bolt 53 gradually moves backward, and the reset spring 500 in the slot 502 resets accordingly. The second top block 3 is reset under the action of the reset spring 500.
