Description

Technical Field

[0001] The utility model relates to the technical field of field effect tube installation, in particular to a tooling fixture for assembling field effect tubes conveniently and quickly. Background Art

[0002] Plug-in field effect tubes generally need to be heat-dissipated and fastened to the heat sink with screws. The heat sink can have threaded holes at any position as required. In this way, you only need to make a positioning fixture, place the plug-in field effect tube at the screw hole at the heat dissipation location, and fasten the plug-in field effect tube to the heat sink securely.

[0003] In order to meet the needs of product design, the plug-in field effect tube needs to be fastened to a piece of aluminum alloy with a thickness of 1.8mm for heat dissipation. Because the aluminum alloy is also the bottom shell of the product, the aluminum alloy bottom shell is too thin to be tapped with threads, and the purpose of fastening cannot be achieved. In addition, when tapping the threads on the aluminum alloy bottom shell and tightening the screws from the field effect tube outward, the three parts of the aluminum alloy bottom shell, screws, and field effect tube will protrude from the bottom surface of the aluminum alloy after tightening due to tolerance reasons, resulting in different lengths, affecting the appearance of the entire product, so the screws can only be penetrated from the outside of the aluminum alloy bottom shell to the field effect tube for fastening.

[0004] Another factor is that nuts must be added to tighten the aluminum alloy base toward the field effect tube. Because the top of the plug-in field effect tube is just a through hole and has no threads, nuts must be added under the field effect tube to tighten it. The operation is cumbersome, increases the difficulty of assembly, and affects the structure of the product.

[0005] In order to solve this problem, a tooling fixture for assembling field effect tubes conveniently and quickly is designed. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] According to the attached Figures 1 to 3 As shown, the fixture for convenient and quick assembly of field effect tubes of the utility model comprises a fixture base 1, a pre-installed nut 2, and a locking assembly 3. The locking assembly 3 can be disassembled and assembled on the fixture base 1, and the locking assembly 3 is provided with an installation slot 4 for embedding the field effect tube 8, a pre-installed position 5 for pre-installed nut 2, and a guide groove 6 for sliding with the product bottom shell 7. The installation slot 4 is provided in the middle of the upper surface of the locking assembly 3, the pre-installed position 5 is provided in the installation slot 4, the guide groove 6 is provided on the upper end surface of the installation slot 4, and the product bottom shell 7 is connected with a fixing screw 9 for threaded connection with the pre-installed nut 2.

[0023] In practical applications, the locking assembly 3 includes a locking seat 31, a locking bolt 32, and a locking nut 33. The clamp base 1 is connected to at least two locking seats 31. One end of the locking bolt 32 is connected to the clamp base 1, and the other end of the locking bolt 32 passes through the clamp base 1 and the locking seat 31 and is threadedly connected to the corresponding locking nut 33 respectively.

[0024] That is, two, three, four or more than four FETs can be installed on the fixture base 1, so that the tooling fixture can be equipped with multiple field effect transistors 8, which is highly practical.

[0025] At the same time, the fixture base 1 is provided with mounting holes for easy installation on the table, and the mounting holes are distributed around the fixture base 1. By fixing it on the table through the mounting holes, it can be easily transferred to other workstations and stored after use, and it has high applicability.

[0026] Moreover, the middle part of the clamp base 1 is provided with at least two groups of adjustment slots 11 for adjusting the installation position of the field effect tube 8, and one end of the locking bolt 32 is clamped on the adjustment slot 11 and can slide along the adjustment slot 11. The locking nut 33 is integrally connected with an operation position 331 for hand tightening.

[0027] However, referring to Figures 1 to 3 As shown, the drawings of the present application only show that there are three groups of adjustment slots 11 in the middle of the clamp base 1. When assembling products of different sizes, the locking nut 33 can be quickly and directly loosened by hand on the operating position 331 to adjust the installation position of the locking bolt 32 in the adjustment slot 11, thereby meeting the position requirements of the field effect tube 8 and reducing the trouble of adjusting with tools.

[0028] Reference Figures 1 to 3As shown, in further detail, two symmetrical sides of the locking seat 31 are respectively provided with through holes 312 for the other end of the locking bolt 32 to pass through.

[0029] Moreover, a convex edge portion 311 is provided in the middle of the upper surface of the locking seat 31. The mounting slot 4 is provided in the middle of the convex edge portion 311. The guide groove 6 is provided on the upper end surface of the convex edge portion 311, and the pre-installed position 5 is provided on the mounting slot 4, and the top end of the pre-installed position 5 is lower than the bottom surface of the mounting slot 4.

[0030] During assembly, first install the pre-installed nut 2 and place it in the installation slot 4. Since the shape of the installation slot 4 is consistent with that of the pre-installed nut 2, the pre-installed nut 2 is effectively fixed to the installation slot 4, replacing the wrench to fix the screw so that it does not move. Then, place the field effect tube 8 in the installation slot 4 in the required direction. When the screw through hole of the field effect tube 8 and the screw hole of the pre-installed nut 2 are aligned, the field effect tube 8 can be fixed without manual alignment, which simplifies the operation procedure and ensures assembly accuracy. After that, slide the product bottom shell 7 onto the guide groove 6 of the convex edge 311 of the locking seat 31. The guide groove 6 can stabilize the product bottom shell 7 and prevent it from being displaced when the fixing screw 9 and the pre-installed nut 2 are threadedly installed.

[0031] In addition, the fixture base 1 is provided with an adjustable positioning clamp 10 for limiting and positioning the product bottom shell 7, and the adjustable positioning clamp 10 is arranged on both sides of the fixture base 1. The adjustable positioning clamp 10 can further accurately align the hole positions of the field effect tube 8 and the pre-installed nut 2, so that the field effect tube 8 is fixedly installed on the product bottom shell 7 by the fixing screw 9. The assembly operation is convenient and the precision is high.

[0032] The above specific embodiments are only specific implementation methods with better effects of the utility model.
