In the process of bonding lead-agent strips to single-crystal blades, the fixture only needs to rotate the clamping seat to complete the process, which can improve the efficiency of bonding lead-agent strips and prevent damage to the blades due to improper operation during assembly, saving manpower and improving the pass rate of the blades. When the operator assembles manually, one hand needs to hold a welding knife and the other hand needs to hold the lead-agent strip, and the blade is placed on the operating table, which is not conducive to bonding two or more lead-agent strips. The lead-agent strips are easily damaged and are bent at a certain angle, which is very troublesome and time-consuming during operation. Meanwhile, each operator has different combination habits, resulting in inconsistent placement of the lead strips on the blades and a low overall blade pass rate. In summary, the rotating blade clamping fixture provided by this invention can improve the operator's lead strip bonding efficiency by 40%.

[0019] 2. The wax mold crystal bonding device and assembly method of the present invention, by respectively fitting two collars onto the outside of the first knurled screw and the second knurled screw, allows the collars to protect the first and second knurled screws and reduce the entry of dust and impurities into the first and second mounting holes. When the first and second knurled screws are used for a long time and are disassembled, the pre-stored lubricating oil in the rubber box enters the collar through the connecting pipe by means of the installed rubber box, and is sprayed out through the outlet and filter screen, thereby lubricating and maintaining the first and second knurled screws. At the same time, the installed filter screen not only disperses the lubricating oil, but also reduces the entry of dust and impurities into the outlet of the collar, effectively preventing impurities from clogging the outlet.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 8As shown in the embodiment of the present invention, a wax mold crystal bonding device includes a rotating clamping fixture for a moving blade. The rotating clamping fixture for the moving blade includes a clamping seat, a support block 9, a support column 11, and a base 8. The clamping seat includes an upper jaw 3, a lower jaw 6 (the height between the upper jaw 3 and the lower jaw 6 is 10-30mm), and a pressing slider 4. A first mounting part is provided on the clamping seat. A first knurled screw 2 is provided inside the upper jaw 3. A first hexagon socket screw 1 is threaded into the upper jaw 3, and the first hexagon socket screw 1 connects the upper jaw 3 and the lower jaw 6. The support block 9 (the length of the support block 9 is 25-75mm, the width is 15-45mm, and the height is 15-45mm) is provided on the support block 9. A second mounting part is provided on the support block 9. The clamping seat and the support block 9 are connected by a rotating shaft 19 (an installation gap is provided between the first mounting part and the rotating shaft 19, and the installation gap ranges from 1). The first mounting part is rotatably connected to the second mounting part (mm to 3mm), and the first mounting part is in contact with the third mounting part. The support block 9 is provided with a rotating insert 10. The top of the support block 9 is provided with a second knurled screw 12 that mates with the rotating insert 10. The support block 9 is provided with a ball thread 13 that connects to the second knurled screw 12. The support block 9 is internally threaded with two pins 14 (the sum of the diameters of the pins 14 and the nuts of the rotating shaft 19 is 7-21mm). The two pins 14 are located on both sides of the rotating shaft 19. The support column 11 (the height of the support column 11 is 100mm-150mm. The distance between the third mounting holes 18 is 5-20mm). The support column 11 is provided with a third mounting part. The support block 9 is fitted onto the surface of the support column 11. The base 8 is connected to the support column 11 by a second internal hexagon screw 7.

[0032] Specifically, a clamping slider 4 is installed inside the upper jaw 3, and a rubber pad 5 is fixedly installed on the top of the lower jaw 6; a first mounting hole 16 penetrating through itself is opened on the top of the upper jaw 3, and the diameter of the first mounting hole 16 is larger than the diameter of the first knurled screw 2; a second mounting hole 17 is opened on the top of the support block 9, and the diameter of the second mounting hole 17 is larger than the diameter of the second knurled screw 12; several third mounting holes 18 are opened on the surface of the support column 11, and a third knurled screw 15 is threaded into the third mounting hole 18, and the diameter of the third mounting hole 18 is larger than the diameter of the third knurled screw 15.

[0033] During operation, the first mounting hole 16 is located above the middle of the upper jaw 3 of the clamping seat, and at least one first mounting hole 16 is located in the middle of the first mounting part. During the installation of the rotating blade clamping fixture, the clamping slider 4 is first placed under the upper jaw 3, and the first mounting hole 16 is aligned with the groove of the clamping slider 4. Finally, the fastener passes through the first mounting hole 16 to fix the clamping slider 4 on the clamping seat, ensuring the stable installation of the clamping seat and the clamping slider 4, and preventing the clamping seat or the clamping slider 4 from moving during rotation.

[0034] Rubber pads 5 are installed on the clamping slider 4 and the lower jaw 6 to protect the blades and reduce friction. A first knurled screw 2 is selected. To facilitate the installation of the clamping seat, the diameter of the first mounting hole 16 is set larger than the diameter of the fastener nut to ensure the positional relationship between the clamping seat and the nut and avoid interference. After the first knurled screw 2 is installed, it passes through the clamping seat via the first mounting hole 16, ensuring stable installation of the clamping seat.

[0035] The card holder and support frame cooperate to form a whole. The card holder and support block 9 are connected by a rotating shaft 19. The card holder has a first mounting part, and one end of the support block 9 has a second mounting part. The first and second mounting parts are adapted to each other to achieve a rotatable connection between the card holder and the support block 9. During the rotation of the card holder, the first and second mounting parts contact each other, thereby adjusting the rotation angle, allowing the operator to flexibly control the rotation angle of the card holder. The support block 9 and support column 11 can be connected by a third knurled screw 15. The support block 9 has a second mounting part, and the support column 11 has a third mounting part. The support column 11 and support block 9 are connected by the third knurled screw 15. The third mounting hole 18 is a through hole with multiple holes of different heights. Connecting different hole positions allows for adjustment of different heights. The tooling provided by this invention allows for the bonding of single-crystal blades with lead strips simply by rotating the holder. This improves the efficiency of bonding lead strips and prevents damage to the blades due to improper operation during assembly, saving manpower while increasing the blade qualification rate.

[0036] When assembling the blades manually, operators need to hold a welding knife in one hand and a lead wire in the other, with the blades placed on the worktable. This is not conducive to bonding two or more lead wires, as the lead wires are easily damaged and bent at an angle, making the operation very cumbersome and time-consuming. Furthermore, each operator has different assembly habits, resulting in inconsistent lead wire bonding positions and a low overall blade pass rate. In summary, the rotating blade clamping fixture provided by this invention can improve the efficiency of lead wire bonding by 40%.

[0037] A rubber box 20 is fixedly installed on the top of the upper jaw 3. The rubber box 20 is pre-filled with lubricating oil. Connecting pipes 21 are fixedly installed on both sides of the rubber box 20. The ends of the two connecting pipes 21 away from the rubber box 20 are close to the first mounting hole 16 and the second mounting hole 17, respectively. A collar 22 communicating with the inside is fixedly installed on the end of the connecting pipe 21 away from the rubber box 20. The two collars 22 respectively wrap around the first knurled screw 2 and the second knurled screw 12. Several liquid outlets 23 are opened on the surface of the collars 22. A filter screen 24 is fixedly installed inside the liquid outlet 23.

[0038] During operation, the two collars 22 are respectively fitted onto the outside of the first knurled screw 2 and the second knurled screw 12, thus protecting the first knurled screw 2 and the second knurled screw 12 and reducing the entry of dust and impurities into the first mounting hole 16 and the second mounting hole 17. When the first knurled screw 2 and the second knurled screw 12 are used for a long time and are disassembled, the pre-stored lubricating oil in the rubber box 20 enters the collar 22 through the connecting pipe 21 by installing the rubber box 20, and is sprayed out through the outlet 23 and the filter screen 24, thereby lubricating and maintaining the first knurled screw 2 and the second knurled screw 12. At the same time, the installed filter screen 24 not only disperses the lubricating oil, but also reduces the entry of dust and impurities into the outlet 23 of the collar 22, effectively preventing impurities from clogging the outlet 23.

[0039] A method for bonding and assembling a wax mold lead crystal structure, the method employing the aforementioned wax mold lead crystal structure bonding device, the method comprising the following steps:

[0040] S1: The card holder and the support frame work together to form a whole. During the rotation of the card holder, the first mounting part comes into contact with the second mounting part, thereby rotating and adjusting to control the rotation angle of the card holder.

[0041] S2: First, press the slider 4 under the upper jaw 3 and align the first mounting hole 16 with the groove of the pressing slider 4. Finally, pass the fastener through the first mounting hole 16 to fix the pressing slider 4 on the card seat, ensuring the stable installation of the card seat and the pressing slider 4.

[0042] S3: Place the bonding strip of the blade to be bonded on the rubber pad 5 of the lower jaw 6, and use the upper jaw 3 to position and bond the bonding strip of the blade to be bonded.

[0043] Working principle: During the installation of the rotating blade clamping fixture, the clamping slider 4 is first placed under the upper jaw 3, and the first mounting hole 16 is aligned with the groove of the clamping slider 4. Finally, the fastener passes through the first mounting hole 16 to fix the clamping slider 4 on the clamping seat, ensuring the stable installation of the clamping seat and the clamping slider 4, and preventing the clamping seat or the clamping slider 4 from moving during rotation.

[0044] The card holder and support frame cooperate to form a whole. The card holder and support block 9 are connected by a rotating shaft 19. The card holder has a first mounting part, and one end of the support block 9 has a second mounting part. The first and second mounting parts are adapted to each other to achieve a rotatable connection between the card holder and the support block 9. During the rotation of the card holder, the first and second mounting parts contact each other, thereby adjusting the rotation angle, allowing the operator to flexibly control the rotation angle of the card holder. The support block 9 and support column 11 can be connected by a third knurled screw 15. The support block 9 has a second mounting part, and the support column 11 has a third mounting part. The support column 11 and support block 9 are connected by the third knurled screw 15. The third mounting hole 18 is a through hole with multiple holes of different heights. Connecting different hole positions allows for adjustment of different heights.

[0045] By fitting two collars 22 onto the outside of the first knurled screw 2 and the second knurled screw 12 respectively, the collars 22 protect the first knurled screw 2 and the second knurled screw 12, reducing the entry of dust and impurities into the first mounting hole 16 and the second mounting hole 17. When the first knurled screw 2 and the second knurled screw 12 are used for a long time and are disassembled, the lubricating oil pre-stored in the rubber box 20 enters the collar 22 through the connecting pipe 21 by installing the rubber box 20, and is sprayed out through the outlet 23 and the filter screen 24, thereby lubricating and maintaining the first knurled screw 2 and the second knurled screw 12. At the same time, the installed filter screen 24 not only disperses the lubricating oil, but also reduces the entry of dust and impurities into the outlet 23 of the collar 22, effectively preventing impurities from clogging the outlet 23.
