Description

Technical Field

[0001] This utility model relates to the technical field of tooling fixtures, and in particular to a detachable brazing fixture. Background Technology

[0002] Brazing is a welding method in which both the workpiece and a filler metal with a melting point lower than the workpiece's melting point are heated simultaneously to the filler metal's melting temperature, and the liquid filler metal fills the gaps between the workpieces to connect them. Brazing results in minimal deformation and smooth, aesthetically pleasing joints, making it suitable for welding precision, complex components made of different materials, such as honeycomb panels, turbine blades, carbide tool blades, and printed circuit boards. Existing technology publication CN205166104U discloses a spring brazing fixture, comprising a lower cover, uprights, pressure plates, clamping plates, springs, and an upper cover. Several uprights connect the lower and upper covers, with the lower ends of the uprights fixed to the lower cover, allowing the upper cover to slide on the uprights. A spring is provided on the extended portion of the upright above the upper cover, with pressure plates and clamping plates at both ends of the spring. However, current brazing fixtures use bolts to lock the guide posts to the base, making disassembly inconvenient. Furthermore, after passing through the brazing furnace, the bolts may stick to the threaded holes of the guide posts, leading to difficulty or inability to disassemble the guide posts, resulting in batches of guide posts being reworked or scrapped. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a detachable brazing fixture that can quickly adjust the overall height of the fixture, facilitate the assembly of products of different heights, and reduce the cost of fixture modification and manufacturing.

[0004] This utility model discloses a detachable brazing fixture, including a base, a fixture, a support component, and a disassembly component. The top of the base is connected to the support component through the disassembly component, and the fixture is installed between the bottom of the support component and the top of the base. The support component and the disassembly component work together to quickly adjust the overall height of the fixture, which is convenient for assembling products of different heights and reduces the cost of fixture modification and manufacturing.

[0005] Preferably, the disassembly components include two cotter pins, multiple sets of gaskets, two flange sleeves, and two guide pillars. The two flange sleeves are welded to the left and right ends of the top of the base. The guide pillars are inserted into the flange sleeves, and the bottom of the guide pillars has insertion holes. Multiple gaskets are fitted onto the lower end of the guide pillars, and cotter pins are inserted into the insertion holes. The guide pillars pass through the flange sleeves and the base, and then multiple gaskets are placed on the guide pillars. The cotter pins are inserted into the insertion holes for fixed connection. The verticality of the guide pillars is controlled by the fit tolerance with the flange sleeves. The use of cotter pins for connection and fixation allows for quick disassembly and assembly of the fixture. When the height of the fixture needs to be increased, the corresponding height gaskets can be removed from the bottom of the guide pillars and installed above the flange sleeves as needed; when the height needs to be reduced, the opposite is true.

[0006] Preferably, the support component includes two columns, a top cover, and two clamping rods. The bottom of the columns is connected to the top of the guide column, the top cover is installed on the top of the columns, and two clamping rods are installed in the middle of the top cover. The clamps are installed on the bottom of the clamping rods and the top of the base by connecting screws.

[0007] Preferably, the upper cover consists of two top plates. A connector is provided at the top of the column. The two top plates are symmetrically provided with limiting holes that are adapted to the top of the column. A connecting hole matching the clamping rod is provided in the middle of the top plate. A clamp is provided at the upper part of the clamping rod, and a spring is fitted at the lower part of the clamping rod. The two-part upper cover is easy to remove from the top of the column and disconnect from the clamping rod, which facilitates the maintenance and replacement of the clamp.

[0008] Compared with the prior art, the beneficial effects of this utility model are: the cooperation of the support component and the disassembly component can quickly adjust the overall height of the fixture, making it convenient to assemble products of different heights and reducing the cost of fixture modification and manufacturing.

[0014] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0015] like Figures 1 to 4As shown, two flange sleeves 4 are welded to the top left and right ends of the base 3. The guide post 5 is inserted into the flange sleeve 4. The bottom of the guide post 5 has an insertion hole. Multiple gaskets 2 are fitted onto the lower end of the guide post 5. The cotter pin 1 is inserted into the insertion hole. The bottom of the column 6 is connected to the top of the guide post 5. The upper cover part 7 is installed on the top of the column 6. Two clamping rods 9 are installed in the middle of the upper cover part 7. The clamp 8 is installed on the bottom of the clamping rods 9 and the top of the base 3 by connecting screws 10. The 7 consists of two top plates. The top of the column 6 is provided with a connector. The two top plates are symmetrically provided with limiting insertion holes that are compatible with the top of the column 6. The middle of the top plate is provided with a connecting hole that matches the clamping rods 9. The upper part of the clamping rods 9 is provided with a clamp. The lower part of the clamping rods 9 is fitted with a spring.

[0016] The guide post 5 passes through the flange sleeve 4 and the base 3. Then, multiple gaskets 2 are placed on the guide post 5 and fixedly connected by inserting cotter pins 1 into the insertion holes. The verticality of the guide post 5 is controlled by the fit tolerance with the flange sleeve 4 and fixed by cotter pins 1, which can realize the quick disassembly and assembly of the fixture. When it is necessary to increase the height of the fixture, the gaskets 2 of the corresponding height can be removed from the bottom of the guide post 5 and installed above the flange sleeve 4 as required. When it is necessary to reduce the height, the opposite is true. The upper cover part 7 composed of two parts is easy to remove from the top of the column 6 and disconnect from the clamping rod 9, which facilitates the maintenance and replacement of the fixture 8.

[0017] like Figures 1 to 4 As shown, this utility model provides a detachable brazing fixture. During operation, after the entire fixture is assembled, the flange sleeve 4 and the base 3 are welded together, reducing the impact of the flange sleeve 4 on the fixture height and facilitating the subsequent disassembly and installation of the guide post. When the fixture height needs to be increased, the corresponding height gasket 2 can be removed from the bottom of the guide post 5 and installed above the flange sleeve 4 as required; when the height needs to be reduced, the opposite is true.

[0018] The above description is only a preferred embodiment 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 technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
