Description

A quick welding tool with screw hole device

technical field

The utility model relates to a quick assembly and welding tool with a screw hole device, which belongs to the technical field of avionics equipment.

Background technique

In the avionics assembly process, during the assembly and welding process of the device with screw holes, the device needs to be fixed with screws on the printed board first, and then removed after the welding is completed. The efficiency is low, the operation is repeated, and after the device screws are removed, it is easy to cause damage due to bumps during the turnover process, resulting in economic losses.

SUMMARY OF THE INVENTION

The purpose of this utility model is to propose a fast welding tool with screw holes. The realization process is briefly summarized as follows: through the use of the tool, the fast fixing of the device with screw holes and the printed board can be realized through the cooperation of the positioning pin and the clamping plate. and disassembly, while avoiding bump damage and scrapping of printed boards in the production process, saving costs.

The technical scheme adopted by the utility model is:

A quick assembly and welding tool with a screw hole device is characterized in that it includes a rectangular top plate 1, a rectangular bottom plate 2, a positioning pin 3, and a pressing component; the rectangular bottom plate 2 is provided with a square through hole in the middle, and the edge is fixed with the positioning pin 3, and the pressing The buckle assembly is installed on the rectangular bottom plate 2, and the rectangular top plate 1 is fixed on the rectangular bottom plate 2 through the buckle assembly.

The pressing button assembly includes a pressing button 4 , a pressing button 5 and a spring 6 ; the spring 6 is sleeved on the pressing button 5 and mounted on one end of the pressing button 4 .

The rectangular top plate 1 is provided with a square through hole in the middle, and the edge of the square through hole is provided with an L-shaped groove.

A circular observation hole is provided at the relative position of the positioning pin 3 on the rectangular top plate 1 and the rectangular bottom plate 2 .

A U-shaped through hole is opened at the relative position of the pressing components on the rectangular top plate 1 and the rectangular bottom plate 2 .

Two sides of the 1U-shaped through hole of the rectangular top plate are provided with circular grooves.

The edges of the square through holes of the rectangular base plate 2 are provided with L-shaped grooves, and the four corners of the rectangular base plate 2 are provided with grooves which communicate with the L-shaped grooves.

The snap assemblies are symmetrically installed on the four corners of the rectangular base plate 2 .

The positioning pins 3 are fixed on the corresponding two sides of the rectangular base plate 2 .

The advantages and beneficial effects of the utility model:

The tooling of the utility model changes the previous disassembly and assembly method of the device with screw holes. The traditional printed board needs to be pre-fixed with screws, so the efficiency is low, and the device is easily damaged during operation and taking, and the loss is huge. The tooling of the utility model can meet the fast welding and turnover protection of various types of devices with screw holes by designing a new tooling mode without changing the original production mode, improving the efficiency and avoiding the risk of damage.
