The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 2 to 4, a metal frame welding jig includes: the argon welding machine comprises a base 100, a fixed seat 200, a welding head 300, an argon welding machine 400 and a positioning rod 500;

the fixing base 200 is fixed on the base 100, and the top end of the fixing base 200 is provided with a positioning block 600 for limiting the freedom degree of the mirror frame main body 900;

the welding head 300 is fixed above the fixed seat 200 through a lifting device 700, and the welding head 300 and the fixed seat 200 are connected with the argon welding machine 400;

the positioning rod 500 is fixedly connected with the welding head 300, and a positioning groove for fixing the hinge block 901 is formed in the lower end of the positioning rod 500. Generally, the material and titanium alloy of the metal frame body 900 are chemically active and easily contaminated with oxygen, nitrogen, or hydrogen, and therefore welding by means of shielded metal arc welding, gas welding such as oxyacetylene or oxypropylene, C02 welding, or atomic hydrogen welding is not possible.

Therefore, the common welding methods for titanium and titanium alloy are as follows: argon arc welding, submerged arc welding, vacuum electron beam welding and the like. The thickness of the alloy is less than 3 mm by argon tungsten-arc welding and more than 3 mm by argon consumable-arc welding. The purity of argon is not lower than 99.99%, and the contents of air and water vapor in the argon are strictly controlled.

When the glasses frame is used for the first time, the relative positions of the fixing seat 200 and the positioning rod 500 are well debugged according to actual conditions, the glasses frame main body 900 is fixed through the fixing seat 200, the hinge block 901 is fixed through the positioning rod 500, and the positioning rod 500 is driven through the lifting device 700. After the mirror frame main body 900 is fixed, the lifting device 700 drives the welding head and the positioning rod 500 with the hinge block 901 to descend, so that the hinge block 901 is in close contact with the mirror frame main body 900, the argon welding machine 400 is started to weld, and the hinge block 901 is welded and fixed at a specified position of the mirror frame main body 900.

In this embodiment, the positioning block 600 includes a first positioning block 601, a second positioning block 602, and a third positioning block 603;

the first positioning block 601 is tightly attached to the inner wall of the mirror frame main body 900, and the second positioning block 602 and the third positioning block 603 are tightly attached to the outer wall of the mirror frame main body 900;

the first positioning block 601, the second positioning block 602, and the third positioning block 603 are used for positioning the frame body 900. The three-point positioning is used for fixing the mirror frame main body 900, so that the degree of freedom of the mirror frame main body 900 in the horizontal direction is limited, the welding precision is ensured, and the production efficiency is improved.

In this embodiment, the positioning block 600 is provided with a sliding groove, a positioning nut is arranged in the sliding groove, and the positioning slider is slidably mounted on the fixing base 200 through the positioning nut. For the mirror frame main body 900 with different positioning, the relative position of the positioning block 600 can be adjusted as soon as possible according to the actual situation, and the universality is improved. The left and right positioning of the mirror frame body 900 is different, so that the hinge block 901 on one side can be welded and processed first, and then the positioning block 600 is adjusted and the other side is welded and processed.

In this embodiment, the argon welder 400 is provided with an argon port 401, and the argon port 401 is connected to the welding head 300 through a gas pipe (not shown). Because titanium and titanium alloy have large chemical activity and are easily polluted by oxygen, nitrogen and hydrogen, the contents of air and water vapor in argon are strictly controlled by the argon with the purity not lower than 99.99%.

In this embodiment, the fixing base 200 is fixed on the base 100 through a moving platform. The relative welding position of the mirror frame main body 900 and the hinge block 901 is adjusted through the moving platform, the operation is simple and convenient, and the debugging, installation and the welding and assembling of the mirror frame main body 900 which is suitable for different specifications are facilitated.

In this embodiment, the motion platform includes an XY axis sliding module 801 and a rotating module 802;

the rotating module 802 is connected with the fixing base 200 and the XY-axis sliding module 801, and the XY-axis sliding module 801 is installed on the base 100. The relative position of the holder 200 in the horizontal plane, that is, the relative position of the holder with respect to the bonding head 300 is changed by the XY-axis slide module 801. The relative angle between the fixing base 200 and the welding head 300 is changed by rotating the module 802, so as to meet the welding requirements of different frame main bodies 900.

In this embodiment, the lifting device 700 is a lifting cylinder. That is, the lifting cylinder drives the welding head 300 to descend for welding, and the argon welder 400 also needs argon for protection, that is, the working time nodes of the air pump are consistent or similar, so that the control center can conveniently drive and control.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
