Description

Technical Field

[0001] The invention relates to a tool for ensuring the angle consistency of double-wing welding pieces of a mounting plate, belonging to the technical field of machinery. Background Art

[0002] At present, the production and processing mode of most aerospace military enterprises is still manual operation. However, with the country's attention to the aerospace field, various military enterprises have successively put the construction of digital production lines on the agenda with the aim of improving product quality and production efficiency.

[0003] In order to build a digital production line, manual operation must be transformed into automated operation. For example, the welding of mounting plates. Mounting plates are mainly used to install resistors, capacitors, diodes and other components. To transform manual welding into automatic welding, it is necessary to solve problems such as poor consistency, low efficiency and low success rate of one-time welding. At present, the automatic welding equipment on the market is based on the automatic welding of horizontal pads, with no obstructions around. The welding of the double-winged welding pieces of the mounting plate is at the welding end in the vertical direction. Before welding, the soldering iron tip and the direction of tin feeding must be determined according to the angle of the first welding piece. However, if the angles of the remaining welding pieces differ too much from the angle of the first welding piece, the welding quality may be uneven. Therefore, ensuring the consistency of the angles of the double-winged welding pieces of the mounting plate is a key factor in ensuring the quality of automatic welding of the mounting plate.

[0004] At present, the industry uses ordinary flat-nose pliers to hook components onto the double-wing solder tabs on the mounting plate for clamping. Ordinary flat-nose pliers do not have unlimited positioning functions and cannot ensure the consistency of the angles of the double-wing solder tabs at different positions on the mounting plate. Summary of the invention

[0005] The technical problem solved by the present invention is: to overcome the deficiencies of the prior art, to provide a tool for ensuring the angle consistency of the double-wing welding pieces of a mounting plate, and to solve the problem that the prior art means cannot ensure the consistency and quality of automatic welding.

[0006] The technical solution of the present invention is: a tool for ensuring the angle consistency of the double-wing welding piece of the mounting plate, comprising a flat-nose pliers with a limiting function and a tool for checking the angle consistency of the double-wing welding piece of the mounting plate;

[0007] The flat-nose pliers are used to ensure that the angles of the double-wing welding pieces remain consistent after being clamped, and include a flat-nose pliers and a circular steel column fixedly mounted on the jaws at one end of the flat-nose pliers and extending beyond the jaws by a certain distance;

[0008] The consistency inspection tool is a heterogeneous L-shape, and the angles of its two sides are determined according to the angles after the double-wing welding piece is clamped by a flat-nose pliers with a limiting function.

[0009] Furthermore, the size of the flat-nose pliers is selected according to 1 / 2 to 2 / 3 of the width of the double-wing welding piece.

[0010] Furthermore, the circular steel column is fixedly connected to the jaws of one end of the flat-nose pliers by two-point welding.

[0011] Furthermore, the diameter of the circular steel column is 2 mm.

[0012] Furthermore, the length of the circular steel column exceeds the jaws of the flat-nose pliers fixedly connected at one end by 11 mm.

[0013] Furthermore, the material of the consistency inspection tool is white nylon.

[0014] A method for ensuring the angle consistency of double-wing welding pieces of a mounting plate, implemented by using the tool for ensuring the angle consistency of double-wing welding pieces of a mounting plate, comprises:

[0015] Using the functional pliers to clamp the double-wing soldering tabs without assembled components;

[0016] Hook the formed component pins onto the double-wing solder tabs;

[0017] Using the functional pliers to clamp the double-wing soldering tabs of the assembled components;

[0018] The consistency inspection tool is used to inspect and confirm the consistency of double-wing welding pieces at different positions.

[0019] Furthermore, the double-wing welding piece is clamped by using the functional pliers, including:

[0020] First, insert the circular steel column into the riveting hole of the double-wing welding piece, limit the jaw position of one end of the functional pliers, then apply force to the handle of the functional pliers, and repeat this operation for double-wing welding pieces at other positions to ensure that the offset angles of the double-wing welding pieces are consistent.

[0021] Furthermore, the consistency of the double-wing welding pieces at different positions is checked and confirmed using the consistency inspection tool, including:

[0022] Place the consistency inspection tooling close to the mounting board surface along the direction of the double-wing soldering piece, the double-wing soldering pieces where the components are located are in a straight line, and the distance between the double-wing soldering piece and the consistency inspection tooling does not exceed a preset range to meet the requirements.

[0023] The advantages of the present invention compared with the prior art are:

[0024] The flat-nose pliers with a limiting function in the present invention clamp the double-wing welding piece after the limiting device is passed through the riveting hole of the double-wing welding piece, which plays a limiting role, that is, it ensures the consistency of the angles of the double-wing welding pieces at different positions after the components are assembled and clamped. In addition, the angle consistency inspection tool for the double-wing welding pieces of the mounting plate in the present invention can be used to check and confirm the consistency of the angles of the double-wing welding pieces at different positions after the components of the mounting plate are assembled, thereby improving the consistency and quality of the automatic welding of the mounting plate.

[0028] In order to better understand the above technical scheme, the technical scheme of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical scheme of the present invention, rather than limitations on the technical scheme of the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0029] The following is a further detailed description of a tool for ensuring the angle consistency of the double-wing weld tabs of a mounting plate provided by an embodiment of the present invention in conjunction with the drawings of the specification. The specific implementation method may include: a flat-nose pliers with a limiting function and a tool for checking the angle consistency of the double-wing weld tabs of a mounting plate. The jaws of one end of the ordinary flat-nose pliers are connected to the φ2 circular steel column by brazing technology to form a flat-nose pliers with a limiting function. The φ2 circular steel column is used to limit the position in the riveting hole of the double-wing weld tab and then clamp it, thereby ensuring that the offset angles of the double-wing weld tabs at different positions of the mounting plate components remain consistent after assembly; in addition, in order to ensure the consistency of the offset angles of the double-wing weld tabs of the mounting plate components, the tool for checking the angle consistency of the double-wing weld tabs of the mounting plate can be used for inspection and confirmation.

[0030] In the solution provided in the embodiment of the present invention, Figure 1-2 A tool for ensuring the angle consistency of double-wing welding pieces on a mounting plate comprises a flat-nose pliers with a limiting function and a tool for checking the angle consistency of double-wing welding pieces on a mounting plate.

[0031] The jaw 1 at one end of the ordinary flat-nose pliers is selected from ordinary flat-nose pliers whose jaw width is 1 / 2 to 2 / 3 of the width of the double-wing welding piece; the φ2 circular steel column 2 is connected to the jaw 1 at one end of the ordinary flat-nose pliers by two-point welding using brazing technology to form a flat-nose pliers with a limiting function, and the length of the φ2 circular steel column 2 should be 11 mm longer than the jaw 1 at one end of the ordinary flat-nose pliers (recommended size).

[0032] The installation plate double-wing welding piece consistency inspection tool 3 is in an "L-shape", and the angles of the two sides of the "L-shape" are determined according to the angles of the double-wing welding piece after being clamped by a flat-nose pliers with a limit function. The material is white nylon. Figure 2 Except for the thickness recommendation design which is consistent with the requirement of "2mm (recommended size)" in the diagram, the other size requirements can be determined according to the actual usage. After the outer dimensions and the angles of both sides of the "special L-shape" are determined, 3D printing technology is used for printing.

[0033] This mounting plate double-wing solder piece angle consistency guarantee tool first uses a flat-nose pliers with a limit function to clamp the double-wing solder piece, and then uses the mounting plate double-wing solder piece consistency inspection tool to check and confirm its forming consistency. The specific use process is: use a flat-nose pliers with a limit function to clamp the double-wing solder piece (without components assembled) → hook the formed component pins onto the double-wing solder piece → use a flat-nose pliers with a limit function to clamp the double-wing solder piece (with components assembled) → use the mounting plate double-wing solder piece consistency inspection tool to check and confirm the consistency of the double-wing solder pieces at different positions.

[0034] The method of using the flat-nose pliers with a limiting function is as follows: first insert the φ2 circular steel column 2 into the riveting hole of the double-wing welding piece, limit the position of the jaws 1 at one end of the ordinary flat-nose pliers, and then apply force to the handle of the flat-nose pliers, and repeat this operation on double-wing welding pieces at other positions to ensure that the offset angles of the double-wing welding pieces are consistent; the method of using the tool for checking the angle consistency of the double-wing welding pieces on the mounting plate is as follows: place the tool close to the surface of the mounting plate along the direction of the double-wing welding piece, the position of the double-wing welding piece where the component is located should be in a straight line, and the distance between the double-wing welding piece and the inspection tool should not exceed ±0.5mm to meet the requirements.
