Description

Technical Field

[0001] This application relates to the field of foolproof fixture technology, and in particular to a foolproof fixture for assisting terminal welding. Background Technology

[0002] Mistake-proof fixtures are the specific application of mistake-proof design in industrial production. They are mainly used to avoid operational errors or assembly mistakes, ensuring the accuracy and safety of the production process. When soldering terminal blocks, it is necessary to pre-match the shape and size of the terminal blocks before placing them into the soldering equipment. This requires a mistake-proof fixture that matches the shape of the terminal blocks.

[0003] Reference Figure 1 Two different shaped terminal blocks 02 and matching foolproof fixtures are disclosed. The foolproof fixture includes a placement plate 1 with positioning holes 011, mounting holes 012, and a placement groove. A positioning post 013 is fixedly connected in the placement groove to limit the terminal block 02. The positioning hole 011 is used to mate with a positioning pin inside the welding equipment, and the mounting hole 012 is used for the mounting bolt inside the welding equipment to pass through, with the mounting bolt pressing against the placement plate 1. During welding, the terminal block 02 is sleeved on the positioning post 013 and located in the placement groove.

[0004] In the existing technology, one type of terminal block shape is only applicable to one type of foolproof fixture. Thus, for terminal blocks of different shapes or sizes, a separate foolproof fixture is required for verification, which is cumbersome in terms of application and classification, and reduces the applicability of foolproof fixtures. Summary of the Invention

[0005] To improve the applicability of the mistake-proof fixture, this application provides a mistake-proof fixture for assisting terminal welding.

[0006] This application provides a foolproof fixture for auxiliary terminal soldering, which adopts the following technical solution:

[0007] A foolproof fixture for assisting terminal welding includes a placement plate with a mounting groove and several sliding grooves. A limiting post is connected to the mounting groove, and the mounting groove communicates with the several sliding grooves. Two clamping blocks are slidably fitted in the sliding grooves. An adjustment assembly is provided on the placement plate, which includes a bidirectional screw and a T-block. A rotating groove is provided on the placement plate at a position corresponding to the sliding groove. The T-block is slidably fitted in the rotating groove and connected to the clamping blocks. The bidirectional screw is rotatably connected in the rotating groove and threadedly engaged with the T-block.

[0008] By adopting the above technical solution, during installation, the bidirectional screw is pre-rotated to move the T-block to the designated position, forming a clamping area of ​​a specified shape between several clamping blocks. The terminal block is then fitted onto the limiting post. If the terminal block cannot be placed, it indicates that the terminal block model is incompatible. The bidirectional screw is then rotated, causing two clamping blocks to simultaneously clamp against the side wall of the terminal block, thus achieving terminal installation. After welding, only a slight reversal of the bidirectional screw is needed, causing the clamping blocks to move slightly in the opposite direction, allowing the terminal block to be removed without damaging the shape of the clamping area. Adjusting the position of the clamping blocks by adjusting the assembly allows for the pre-formation of a clamping area of ​​a specified shape between several clamping blocks to match the specified specifications of the terminal block. This allows for adjustment of the clamping block position to accommodate various terminal block specifications, ensuring compliance with specifications. Furthermore, the clamping blocks reduce the possibility of rotation during terminal welding. Finally, it facilitates the application and categorized storage of the error-proof fixture, improving its applicability.

[0009] Optionally, the placement plate includes a mounting plate and an assembly plate, the mounting groove, the clamping block and the adjusting component are all disposed on the assembly plate, and the mounting plate is provided with a locking component to restrict the movement of the assembly plate.

[0010] By adopting the above technical solution, and by setting up a mounting plate, assembly plate, and locking components, the assembly plate can be replaced. If the maximum size of the mounting slot inside an assembly plate cannot meet the installation requirements of the wiring terminals, a larger assembly plate can be replaced, while the mounting plate does not need to be replaced, thus improving the versatility of the foolproof fixture.

[0011] Optionally, the locking assembly includes a connecting strip, a limiting plate, and a locking bolt. The connecting strip is connected to the end of the mounting plate and is a T-shaped strip. The mounting plate has a mounting groove on its side, with one end of the mounting groove open. The connecting strip slides within the mounting groove. The opening of the mounting groove has a placement notch and a limiting groove, which communicate with each other. The limiting plate slides within the limiting groove and blocks the connecting strip. The locking bolt passes through the limiting plate and the mounting plate and is threaded into the mounting plate.

[0012] By adopting the above technical solution, when locking the assembly plate, the connecting strip is slidably fitted into the assembly groove, and then the limiting plate is inserted into the limiting groove through the placement notch to block the connecting strip. Finally, the locking bolt is rotated until the limiting plate is pressed against the mounting plate to restrict the degree of freedom of the assembly plate, thus realizing the installation of the assembly plate.

[0013] Optionally, the mounting slot is provided with a plurality of prefabricated wires, and each prefabricated wire corresponds to a terminal block of a certain specification.

[0014] By adopting the above technical solution, the prefabricated line allows workers to quickly adjust the position of the clamping blocks in advance without having to find the distance value between the two corresponding clamping blocks, which facilitates the installation of the wiring terminals.

[0015] Optionally, one end of the bidirectional screw is connected to a cross rotating head, which is located outside the assembly plate.

[0016] By adopting the above technical solution and setting a cross-shaped rotating head, it is convenient for workers to rotate the bidirectional screw, which facilitates the adjustment of the position of the clamping block.

[0017] Optionally, a baffle is connected to the end of the rotating groove, the bidirectional screw passes through the baffle, and an anti-loosening nut is threaded onto the other end of the bidirectional screw, the anti-loosening nut abutting against the baffle.

[0018] By adopting the above technical solution, there is a possibility that the bidirectional screw may rotate due to vibration during the welding of the terminal blocks, causing the clamping block to move and the terminal blocks to deflect. By setting an anti-loosening nut, the possibility of the bidirectional screw rotating is reduced, thus restricting the welding process of the terminal blocks throughout and ensuring the welding quality of the terminal blocks.

[0019] Optionally, the end of the abutting block is provided with an abutting arc surface, and two abutting blocks inside the same sliding groove are arranged opposite to each other, the abutting arc surface being used to abut the wiring terminal.

[0020] By adopting the above technical solution and setting a clamping arc surface, the contact between the clamping block and the terminal block is a line contact, thus enabling the clamping block to adapt to the shape of different specifications of terminal blocks.

[0021] Optionally, a limiting head is provided on the abutting arc surface, and during installation, the wiring terminal is located between the limiting head and the bottom wall of the mounting groove.

[0022] By adopting the above technical solution, the clamping block clamps the terminal block, providing horizontal restriction. However, the degree of freedom of the terminal block in the length direction corresponding to the limiting post is not restricted, leading to tilting of the terminal block and reducing its welding stability. By setting a limiting head, the terminal block is positioned between the limiting head and the bottom wall of the mounting groove during installation, restricting the degree of freedom of the terminal block in the length direction corresponding to the limiting post and improving the welding stability of the terminal block.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During installation, pre-rotate the bidirectional screw to move the T-block to the designated position, forming a clamping area of ​​a specified shape between several clamping blocks. Then, place the terminal block onto the limiting post. If the terminal block cannot be placed, it indicates that the terminal block model is incompatible. Then, rotate the bidirectional screw to move two clamping blocks simultaneously against the side wall of the terminal block, thus installing the terminal block. After welding, simply reverse the bidirectional screw slightly, and the clamping blocks will move slightly in the opposite direction, allowing the terminal block to be removed without damaging the shape of the clamping area. Adjusting the position of the clamping blocks by adjusting the assembly allows for the pre-formation of a clamping area of ​​a specified shape between several clamping blocks to match the specified specifications of the terminal block. This allows for adjustment of the clamping block position to accommodate various terminal block specifications, ensuring compliance with specifications. Furthermore, the clamping blocks reduce the possibility of rotation during terminal welding. Finally, this facilitates the application and categorization of the error-proof fixture, improving its applicability.

[0025] 2. When locking the assembly plate, slide the connecting strip into the assembly groove, then insert the limiting plate into the limiting groove through the placement notch to block the connecting strip. Finally, rotate the locking bolt until the limiting plate is pressed against the mounting plate to restrict the degree of freedom of the assembly plate, thus realizing the installation of the assembly plate.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 2-6 This application will be described in further detail.

[0034] This application discloses a foolproof fixture for assisting terminal soldering. (See also...) Figure 2 The foolproof fixture for assisting terminal soldering includes a placement plate 1, which includes a mounting plate 11 and an assembly plate 12. The mounting plate 11 has positioning holes 011 and mounting holes 012.

[0035] Reference Figure 3 A locking assembly 2 is provided between the mounting plate 11 and the assembly plate 12. The locking assembly 2 includes a connecting strip 21, a limiting plate 22, and a locking bolt 23. The connecting strip 21 is a T-shaped strip and is fixedly connected to the side of the assembly plate 12. The side of the mounting plate 11 has an assembly groove with one end open. The open end of the assembly groove has a placement notch 111 and a limiting groove 112, which are connected. The limiting plate 22 slides within the assembly groove through the placement notch 111 and blocks the connecting strip 21. The locking bolt passes through the limiting plate 22 and the mounting plate 11 and is threaded into the mounting plate 11. The locking bolt 23 abuts against the limiting plate 22.

[0036] When installing the assembly plate 12, the connecting strip 21 is slidably fitted into the assembly groove, and the limiting plate 22 is slidably fitted into the limiting groove 112 to seal the connecting strip 21. Finally, the locking bolt 23 is rotated to restrict the degree of freedom of the limiting plate 22, thus realizing the installation of the assembly plate 12.

[0037] Reference Figure 4 , Figure 5 and Figure 6The assembly plate 12 has an installation groove 121 and several sliding grooves 122. In this embodiment, three sliding grooves 122 are used as an example. The installation groove 121 connects the three sliding grooves 122, and a limiting post 123 is fixedly connected in the installation groove 121. Two abutting blocks 3 are provided in the sliding groove 122. The ends of the abutting blocks 3 are provided with abutting arc surfaces 31. The two abutting blocks 3 in the same sliding groove 122 are arranged opposite to each other. The abutting arc surfaces 31 facilitate the contact between the abutting blocks 3 and the terminal 02. A limiting head 32 is fixedly connected to the abutting block 3. A limiting step is formed between the limiting head 32 and the abutting arc surface 31. During installation, the terminal 02 is located between the limiting head 32 and the bottom wall of the installation groove 121.

[0038] Reference Figure 2 , Figure 5 and Figure 6 An adjustment assembly 4 is provided on the assembly plate 12. The adjustment assembly 4 includes a bidirectional screw 41 and a T-block 42. The T-block 42 is fixedly connected to the clamping block 3. A rotating groove is opened on the assembly plate 12 at the position corresponding to the sliding groove 122, and the T-block 42 is slidably fitted in the rotating groove. The bidirectional screw 41 is rotatably connected in the rotating groove and is threadedly engaged with the T-block 42. A cross rotating head 411 is fixedly connected to one end of the bidirectional screw 41. The cross rotating head 411 is located outside the assembly plate 12 and is used to facilitate the operation of the bidirectional screw 41. A baffle 124 is fixedly connected to the end of the rotating groove. The other end of the bidirectional screw 41 passes through the baffle 124 and is threadedly engaged with an anti-loosening nut 412, which abuts against the baffle 124. The anti-loosening nut 412 is used to prevent the bidirectional screw 41 from being loosened.

[0039] Reference Figure 4 To improve the ease of installation of the terminal block 02, several pre-fabricated wires 125 are provided on the bottom wall of the mounting groove 121. In this embodiment, two are used as an example, with each pre-fabricated wire 125 corresponding to a different specification of terminal block 02. Workers can quickly adjust the position of the clamping block 3 by relying on the pre-fabricated wires 125 without measuring the distance between the two clamping blocks 3.

[0040] The implementation principle of a foolproof fixture for auxiliary terminal welding in this application embodiment is as follows: Before welding, the connecting strip 21 is slidably fitted in the assembly groove, and then the limiting plate 22 is slidably fitted in the limiting groove 112. The locking bolt 23 is rotated to install the assembly plate 12. Then, the bidirectional screw 41 is rotated to move the clamping block 3 until the limiting head 32 reaches the position of the prefabricated line 125. The terminal 02 is sleeved on the limiting post 123. Then, the bidirectional screw 41 is rotated to clamp the arc surface 31 to the side wall of the terminal 02. Finally, the anti-loosening nut 412 is rotated to realize the installation of the terminal 02.

[0041] By adjusting the position of the clamping block 3 using the adjusting component 4, a clamping area of ​​a specified shape is pre-formed between several clamping blocks 3 to match the specified specifications of the terminal 02. On the one hand, the position adjustment of the clamping block 3 can adapt to various different specifications of terminal 02 to determine whether the terminal 02 meets the specified specifications. On the other hand, by using the clamping block 3 to clamp the terminal 02, the possibility of rotation during terminal welding is reduced. Furthermore, it facilitates the application and classification of the error-proof fixture, and improves the applicability of the error-proof fixture.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
