Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary tools for welding, and particularly relates to a jig for uniformly laying FAB welding iron powder and a using method thereof. Background Art

[0002] The FAB welding seam is a V-shaped groove. After the gasket is pasted, it is necessary to uniformly lay the welding iron powder flux in the groove. In production practice, after tearing open the bag of iron powder, it is manually poured near the weld bead. This not only easily causes the accumulation of iron powder inside and outside the weld bead, but also requires manually sweeping all the iron powder into the weld bead and then manually leveling and tidying it up a second time. It is time-consuming and laborious, and the laying of iron powder is uneven, and the quality is average. Summary of the Invention

[0003] The purpose of the present invention is to provide a jig for uniformly laying FAB welding iron powder and a using method thereof in view of the deficiencies of the prior art, which can improve the quality of iron powder laying while reducing the labor intensity of operators.

[0004] In order to achieve the above-mentioned invention purpose, the following technical solutions are adopted for the jig for uniformly laying FAB welding iron powder and the using method thereof in the present invention:

[0005] A jig for uniformly laying FAB welding iron powder includes an iron powder storage tube. An iron powder storage cavity for accommodating FAB welding iron powder is arranged inside the iron powder storage tube. One end of the iron powder storage tube is provided with an iron powder outlet tube for guiding and discharging the FAB welding iron powder in the iron powder storage tube.

[0006] A flow rate adjusting assembly is arranged at the position of the iron powder storage tube close to the iron powder outlet tube. The flow rate adjusting assembly includes a fixed insert and a sliding insert. The fixed insert is fixedly arranged on the inner wall of the iron powder storage tube. The sliding insert movably penetrates the iron powder storage tube, and both ends of the sliding insert penetrate out of the iron powder storage tube. The fixed insert and the sliding insert are in sliding contact with each other. The fixed insert is provided with a fixed hole communicating with the iron powder storage cavity, and the sliding insert is provided with a sliding hole. The sliding insert adjusts the overlapping state between the fixed hole and the sliding hole through sliding, and the sliding insert is provided with an elastic pressing part for driving its sliding.

[0007] Preferably, the elastic pressing part includes a button arranged at one end of the sliding insert. A spring is arranged between the button and the outer wall of the iron powder storage tube. The spring drives the sliding hole of the sliding insert to be completely misaligned with the fixed hole, blocking the FAB welding iron powder from flowing into the iron powder outlet tube. By pressing the button down to drive the displacement of the sliding insert, the coaxial alignment degree of the sliding hole and the fixed hole is adjusted, changing the flow cross-sectional area, thereby controlling the flow rate of the FAB welding iron powder; when the button is released, the sliding insert is driven to reset by the release of the elastic potential energy of the spring. At this time, the sliding hole and the fixed hole are completely misaligned, blocking the FAB welding iron powder from flowing into the iron powder outlet tube.

[0008] Preferably, the iron powder outlet pipe is detachably mounted on the iron powder storage pipe, one end of the iron powder outlet pipe is provided with a connector that is threadedly connected to the iron powder storage pipe, and the other end of the iron powder outlet pipe is provided with a discharge port for facilitating the discharge of FAB welding iron powder. The provision of the connector facilitates disassembly and installation.

[0009] Preferably, the iron powder outlet tube is disposed at the center of the connecting joint, and the end surface of the connecting joint that interfaces with one end of the iron powder storage tube is configured as an inner concave surface, with the iron powder outlet tube located at the lowest point of the inner concave surface. The inner concave surface facilitates the smooth flow of FAB welding iron powder into the iron powder outlet tube.

[0010] Preferably, one end of the iron powder storage tube is provided with an iron powder outlet tube, and the other end of the iron powder storage tube is provided with a sealing plug. The provision of the sealing plug facilitates the feeding and recovery of FAB welding iron powder.

[0011] Preferably, the sliding insert is vertically inserted into the iron powder storage tube, with an upper socket provided on the upper wall of the iron powder storage tube and a lower socket provided on the lower wall of the iron powder storage tube. The sliding insert is configured as a trapezoidal structure, with the lower base of the trapezoidal structure being longer than the upper base, the upper base of the trapezoidal structure extending through the upper socket, and the button being provided on the upper base of the trapezoidal structure. The lower base of the trapezoidal structure extending through the lower socket, with the lower base of the trapezoidal structure being longer than the lower socket. By configuring the sliding insert as a trapezoidal structure, when the spring is reset, the lower base of the trapezoidal structure being longer than the lower socket, thereby acting as a limiter, ensuring that the lower end of the sliding insert always extends outside the iron powder storage tube.

[0012] Preferably, the iron powder storage tube is provided with a hook. After the FAB welding iron powder is laid, the iron powder storage tube is hung in the tool box via the hook.

[0013] A method for using a FAB solder powder uniformly laying jig includes the following steps:

[0014] (1) Open the sealing plug and put the FAB soldering iron powder into the iron powder storage chamber;

[0015] (2) Hold the iron powder storage tube and keep it tilted, with the outlet of the iron powder outlet tube facing the weld;

[0016] (3) Press the button until the sliding hole overlaps with the fixed hole. The overlapping flow channel is used for the FAB soldering iron powder to flow. The FAB soldering iron powder flows into the iron powder outlet pipe under the action of gravity and finally falls from the outlet to the weld.

[0017] (4) By pressing the button, the coaxial alignment between the sliding hole and the fixed hole is adjusted to achieve flow regulation of FAB soldering iron powder;

[0018] (5) Keep pressing the button continuously, and hold the iron powder storage tube by hand to evenly lay the FAB welding iron powder along the weld bead.

[0019] (6) After laying, release the button, the spring resets, and the sliding hole of the sliding insert is completely misaligned with the fixed hole, blocking the continuous inflow of FAB welding iron powder into the iron powder outlet tube.

[0020] (7) Open the sealing plug and recycle the excess FAB welding iron powder.

[0021] (8) After installing the sealing plug, hang the iron powder storage tube in the toolbox through the hook.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The present invention sets a flow rate adjustment component to adjust the iron powder flow rate, and drives the sliding insert to slide to adjust the overlapping state between the sliding hole and the fixed hole; when the sliding hole and the fixed hole are completely aligned, the flow channel formed by the two holes is the largest, and thus the flow rate of the FAB welding iron powder is maximized. Therefore, by adjusting the coaxial alignment degree between the sliding hole and the fixed hole, the cross-sectional area of the flow-through is changed, thereby controlling the flow rate of the FAB welding iron powder; when the sliding hole and the fixed hole are completely misaligned, at this time, there is no overlap between the two holes, and the flow of the FAB welding iron powder is blocked, so that it will not enter the iron powder outlet tube; the overall design of the present invention is simple, the iron powder flow rate is controllable, the iron powder output is smooth, and the laying quality is improved.

[0024] 2. The present invention can complete the operation process quickly at one time through the jig, and the labor intensity of the operator is greatly reduced. Description of the Drawings
