Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, and in particular to a tooling structure for welding an inertial navigation board and a main control board. Background Technology

[0002] In the manufacturing process of electronic devices such as inertial navigation systems, the inertial navigation board and the main control board are usually welded together in a mutually perpendicular layout. This process has high requirements, and it is necessary to ensure that the two boards maintain a precise mutually perpendicular relationship throughout the welding process. However, in the existing technology, rigid clamping can easily damage the precision components on the inertial navigation board, while simple slots cannot effectively limit the board's wobble, resulting in poor welding accuracy and low product yield. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a tooling structure for keeping the inertial navigation board and the main control board perpendicular to each other during welding.

[0004] This utility model is achieved through the following technical solution: A tooling structure for welding an inertial navigation board to a main control board includes a base, wherein the base is provided with a vertical slot for vertically inserting the inertial navigation board; The base has upwardly extending mounting seats on both sides of the vertical slot, and the area between the two mounting seats is used to accommodate the inertial navigation plate and to horizontally mount the main control board. The vertical slot is equipped with a flexible limiting device, which acts on the left and right edges of the inertial navigation board to keep the inertial navigation board in a vertical state, thereby realizing the vertical positioning between the inertial navigation board and the main control board for welding.

[0005] As a further improvement of this utility model, the vertical slot includes a first insertion part and a second insertion part. The first insertion part is used for vertical insertion of the inertial navigation plate body, and the second insertion part is used to accommodate electrical components on the inertial navigation plate body. The connection between the first insertion part and the second insertion part is provided with a step for abutting against the two side edges of the inertial navigation plate.

[0006] As a further improvement of this utility model, the flexible limiting device includes a stop block that can slide along the width direction of the vertical slot. The stop block is provided with a stop boss that cooperates with the stop step to jointly clamp the two sides of the inertial navigation plate. A third insertion part is formed between the two stop bosses to accommodate the wiring part of the inertial navigation plate.

[0007] As a further improvement of this utility model, a guide rod is installed on the base, and the abutment block is slidably disposed on the guide rod; a first compression spring is provided between the guide rod and the abutment block for pushing the abutment block so that the abutment boss and the abutment step cooperate to clamp the edge of the inertial guide plate.

[0008] As a further improvement of this utility model, a pull rod is provided on the side of the abutment block away from the first compression spring.

[0009] As a further improvement of this utility model, the mounting bases on both sides are provided with anti-deviation devices to limit the main control board from shifting in the horizontal plane.

[0010] As a further improvement of this utility model, the anti-deviation device includes receiving grooves formed on the opposite inner sidewalls of the mounting seats on both sides, the receiving grooves being used to support and limit the opposite two sides of the main control board; Among them, at least one of the mounting bases is provided with a movable abutment, which is used to apply force to one side of the main control board placed in the receiving groove, so that its other side is tightly fitted with the groove wall of the receiving groove on the opposite side.

[0011] As a further improvement of this utility model, the mounting base is provided with a vertically guiding movable rod, the abutment is inserted through the movable rod and can slide up and down along it, the inner side of the abutment is formed with an inclined pressing slope, and a second compression spring in a pre-compressed state is sleeved on the movable rod. The second compression spring acts on the abutment to provide it with a continuous downward driving force, so that the pressing slope can move downward and toward the main control board, thereby applying a force pointing toward the opposite side wall of the main control board.

[0012] As a further improvement of this utility model, a clearance groove is provided on the mounting base on the side away from the abutment member, and a clearance hole is provided at the bottom of the clearance groove to pass through the mounting base. The clearance hole is used to avoid the capacitor module protruding on the board surface when the main control board is close to the groove wall, so as to prevent the capacitor module from interfering with the mounting base.

[0013] As a further improvement of this utility model, the base has at least one clearance notch in the area corresponding to the lower surface of the main control board, for clearance of electrical components located below the main control board.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0018] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0019] refer to Figures 1 to 5 The present utility model embodiment discloses that: A tooling structure for welding an inertial navigation board (INS) to a main control board includes a base 1 with a vertical slot 2 for vertically inserting an INS 3. The base 1 has upwardly extending mounting seats 4 on both sides of the vertical slot 2, forming a space between the mounting seats 4 to accommodate the INS 3 and to horizontally support the main control board 5. A flexible limiting device is provided in the vertical slot 2, acting on the left and right edges of the INS 3 to keep it vertical, thus achieving vertical positioning between the INS 3 and the main control board 5 for welding. When welding is required, the INS 3 is first vertically inserted into the vertical slot 2 and then limited by the flexible limiting device to ensure the INS 3 remains vertical. The main control board 5 is then horizontally mounted, so that the main control board 5 and the inertial navigation board 3 are in a perpendicular state, as shown in the figure. The upper end of the inertial navigation board 3 is provided with a welding protrusion, and the main control board 5 is provided with a welding slot. The two are matched and then welded to the contact parts. In this embodiment, the cooperation of the vertical slot 2 and the flexible limiting device ensures that the inertial navigation board 3 is strictly in a vertical state and that the main control board 5 is horizontally mounted between the two mounting seats 4, providing a basis for the vertical welding of the horizontal main control board 5 and the inertial navigation board 3. The "flexible limiting" adaptive clamping avoids the squeezing damage to the inertial navigation board 3 and its components by the rigid clamp. The operation of vertically inserting the inertial navigation board 3 and horizontally mounting the main control board 5 is simple and fast, improving production efficiency.

[0020] Since the inertial navigation plate 3 is not a flat plate, it integrates highly protruding electrical components that cannot be accommodated by ordinary slots. This can easily lead to the inertial navigation plate 3 not being able to be installed properly or the components being damaged during installation. Therefore, in this embodiment, the vertical slot 2 includes a first insertion part 301 and a second insertion part 302. The first insertion part 301 is used for vertical insertion of the main body of the inertial navigation plate 3, and the second insertion part 302 is used to accommodate the electrical components on the plate of the inertial navigation plate 3. The "second insertion part 302" provides clearance space for the protruding electrical components, avoiding damage to the electrical components on the plate of the inertial navigation plate 3. The vertical installation of the inertial navigation plate 3 is achieved by the cooperation of the first insertion part 301 and the second insertion part 302. In this embodiment, a step 6 is provided at the connection between the first insertion part 301 and the second insertion part 302. The step 6 extends vertically and is used to abut against the two side edges of the inertial navigation plate 3. When the inertial navigation plate 3 is vertically inserted, the plate of the inertial navigation plate 3 is located inside the first insertion part 301, and its two side edges are in contact with the step 6.

[0021] In this embodiment, the flexible limiting device includes a sliding abutment block 7 that can slide along the width direction of the vertical slot 2. The abutment block 7 has abutment protrusions 8 at both ends that cooperate with the abutment step 6 to jointly clamp the two sides of the inertial navigation plate 3. A third insertion part 303 is formed between the two abutment protrusions 8 to accommodate the wiring part of the inertial navigation plate 3. The sliding abutment block 7 and the abutment step 6 cooperate to form an adaptive clamping mechanism, thereby clamping the two sides of the inertial navigation plate 3, compensating for plate tolerances, and making the clamping more reliable. At the same time, the third insertion part provides clearance space for the wiring part on the side of the plate to prevent it from being pinched or squeezed.

[0022] Specifically, a guide rod 9 is installed on the base 1, and the abutment block 7 is slidably disposed on the guide rod 9. The guide rod 9 ensures that the abutment block 7 can only move smoothly in a predetermined direction (along the width direction of the vertical slot 2), preventing the abutment block 7 from tilting or jamming. A first compression spring 10 is provided between the guide rod 9 and the abutment block 7. The first compression spring 10 is in a pre-compressed state and acts on the abutment block 7 to push the abutment block 7, so that the abutment boss 8 and the abutment step 6 cooperate to clamp the edge of the inertial guide plate 3.

[0023] A pull rod 11 is provided on the side of the abutment block 7 away from the first compression spring 10. The operator can pull the abutment block 7 to overcome the force of the first compression spring 10 and quickly release the clamped inertial guide plate 3, thereby improving the material changing efficiency.

[0024] Furthermore, if only the inertial navigation board 3 is positioned, and the main control board 5 is simply horizontally mounted on the mounting bases 4 on both sides without any constraint on the horizontally placed main control board 5, it is easily affected by external forces during the welding process and may shift or rotate, leading to incorrect welding position. Based on this, in this embodiment, the mounting bases 4 on both sides are provided with anti-deviation devices to limit the main control board 5 from shifting in the horizontal plane. The anti-deviation devices include receiving grooves 12 formed on the opposite inner sidewalls of the mounting bases 4 on both sides. The receiving grooves 12 are used to support and limit the main control board. The main control board 5 has two opposite sides; wherein, at least one of the mounting bases 4 is provided with a movable abutment 14, the abutment 14 is used to apply force to one side of the main control board 5 placed in the receiving groove 12, so that its other side is tightly fitted with the groove wall of the receiving groove 12 on the opposite side; when the main control board 5 is installed, it is placed in the receiving groove 12 between the two mounting bases 4, and the side of the main control board 5 is fitted with the groove wall of the receiving groove 12, thereby restricting the main control board 5 from shifting or rotating, and thus preventing the welding position error.

[0025] Furthermore, the mounting base 4 is provided with a vertically guiding movable rod 13. The abutment 14 passes through the movable rod 13 and can slide up and down along it. The inner side of the abutment 14 forms an inclined pressing slope. A second compression spring 15 in a pre-compressed state is sleeved on the movable rod 13. The second compression spring 15 acts on the abutment 14, providing it with a continuous downward driving force, so that the pressing slope can move downward and toward the main control board 5, thereby applying a force to one side of the main control board 5 pointing toward the opposite side groove wall. When the second compression spring 15 drives the abutment 14 to move downward, the pressing slope acts on the side of the main control board 5, applying a horizontal component force to the side of the main control board 5, thereby causing the main control board 5 to move toward the groove wall of the opposite mounting base 4 and finally abut against the groove wall. During installation, the operator only needs to put the main control board 5 into the receiving groove 12, and the mechanism will automatically complete the pressing and positioning under the action of the second compression spring 15, without any additional locking action, which greatly improves production efficiency.

[0026] In addition, there may be protruding tall components (such as capacitor modules) on the surface of the main control board 5, which may prevent the main control board 5 from falling completely into the receiving groove 12 and sticking to the groove wall, affecting the positioning accuracy, or even damaging the components. Based on this, a clearance groove 16 is provided on the mounting base 4 on the side away from the abutment 14. A clearance hole 17 is provided at the bottom of the clearance groove 16, which passes through the mounting base 4. The clearance hole 17 is used to avoid the capacitor module protruding on the surface of the main control board 5 when it is sticking to the groove wall, so as to prevent the capacitor module from interfering with the mounting base 4. In addition, at least one clearance notch 18 is provided on the area corresponding to the lower surface of the main control board 5 to avoid other electrical components located below the main control board 5.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
