Description

Technical Field

[0001] The utility model relates to the technical field of fixing jigs, and particularly relates to a fixing jig for a high-precision reflow soldering device. Background Art

[0002] Reflow soldering technology is not unfamiliar in the field of electronic manufacturing. Components on various boards used in our computers are all soldered to the circuit board through this process. There is a heating circuit inside this device that heats air or nitrogen to a high enough temperature and then blows it onto the circuit board with components already attached, causing the solder on both sides of the components to melt and bond with the main board. The advantages of this process are that the temperature is easy to control, oxidation can be avoided during the soldering process, and the manufacturing cost is easier to control.

[0003] Generally, large reflow soldering devices come with a base fixing tooling, but they are all made according to specific products and are integrated. When different products need to be made, the entire base has to be directly replaced, resulting in poor adaptability. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a fixing jig for a high-precision reflow soldering device, which has a simple structure, is easy to install, has accurate positioning, strong fixing, and can be directly fixed inside a numerical control machine tool, with a wide range of applications.

[0005] To solve the above technical problem, the utility model provides a fixing jig for a high-precision reflow soldering device, including a bottom plate. A bottom mold is arranged on the bottom plate, and a workpiece is arranged on the bottom mold. Installation grooves are arranged on two adjacent sides of the bottom plate, and fixing components adapted to the bottom mold are arranged in the installation grooves. Clamping components are arranged on the installation plate on both sides of the bottom mold; the fixing component includes a push block, a guide shaft is arranged at the bottom of the push block, and an arc-shaped plate is arranged at the end of the guide shaft; the clamping component includes a limit seat, a limit shaft is arranged on the limit seat, a moving block is arranged on the limit shaft, a spring is sleeved on the periphery of the exposed position of the limit shaft, and a clamping block is arranged on the moving block.

[0006] Furthermore, a limit profile is arranged on the bottom plate near the bottom mold.

[0007] Furthermore, the arc-shaped plates included in the two fixing components are of adapted shapes.

[0008] Furthermore, the fixing component includes a limit block, the guide shaft penetrates through the limit block, a push plate is arranged on the guide shaft, a top block is arranged at the upper end of the push plate, and the top block is adapted to the bottom mold.

[0009] Further, a stepped seat is provided at one end of the bottom mold, a protruding block is provided on the clamping block near the stepped seat, and a side fixing block is provided on the clamping block near the upper part of the bottom mold.

[0010] Further, an auxiliary positioning plate is provided on one side of the bottom mold.

[0011] The beneficial effects of the present utility model: When the device is in use, first, the bottom plate is fixed at the preset processing table position. After fixation, the bottom mold is placed, and the workpiece is fixed on the bottom mold. After fixation, the push block of the fixing component is pushed by an external cylinder or other mechanisms. The push block drives the arc plate to move through the guiding shaft at the bottom. The shapes of the two arc plates are just adapted, so when one of them moves, it will drive the other to move, thereby realizing clamping on both sides at the same time. The movement of the push block drives the movement of the push plate on one side, that is, drives the top block to move until it contacts the bottom mold to achieve the fixing effect on the bottom mold;

[0012] And after the bottom mold is fixed, at this time, the clamping component has already achieved the clamping effect. Due to the elastic potential energy, the spring drives the moving block to approach the bottom mold, and the clamping plate on the moving block will contact the bottom mold to also achieve clamping and fixing.
