DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.

[0021] Embodiment 1:

[0022] Combined with Figure 1-Figure 5 As shown, an ultra-small welding filter welding fixture tooling includes a base plate 1, a carrier plate 2, a positioning plate 3 and at least one group of support plates 5, wherein the base plate 1, the carrier plate 2 and the positioning plate 3 are all plate-shaped frame structures and are arranged parallel to each other and perpendicular to the support plate 5, at least one group of support plates 5 are arranged on both sides of the base plate 1, the carrier plate 2 and the positioning plate 3, and the support plate 5 is provided with a first clamping member (i.e., a second groove 53) for clamping with the base plate 1, a second clamping member (i.e., a first groove 52 ) and a third clamping piece (i.e., an arc-shaped clamping piece 51) for clamping with the positioning plate 3; the support plate 5 is used to connect the three plate surfaces, the bottom plate 1 is provided with at least two rows of first through holes 13, a first square groove 11 is provided between the two rows of the first through holes 13, the loading plate 2 is provided with a second through hole 21 and a second square groove 22 respectively matching the first through hole 13 and the first square groove 11; the positioning plate 3 is provided with a third through hole 31 and a third square groove 32 respectively matching the first through hole 13 and the first square groove 11.

[0023] Since there are leads at both ends of the ultra-small filter (workpiece), the workpiece needs to be fixed during the assembly process, and the length of the workpiece lead from the part assembly is certain. In order to ensure the coaxiality requirements of the lead and the outer shell, both sides of the lead need to be positioned and clamped, thereby reducing the dimensional deviation of the workpiece, improving the accuracy of the workpiece, and effectively preventing and reducing the deformation of the weldment; the workpiece is in the best welding position, the process defects are significantly reduced, and the processing efficiency is improved. It can be seen from the workpiece that the leads at both ends of the workpiece are positioned in parallel by the base plate and the positioning plate, and the middle carrier plate is positioned. The lower end of the workpiece lead passes through the base plate, is spot-fixed and welded on the carrier plate of the tooling, and after all workpieces have completed the above process, the positioning plate is covered, and the upper end lead of the workpiece passes through the positioning plate of the fixture to complete the positioning and tightening, and finally solidifies to complete the welding. By setting the above structure, the present invention can batch weld multiple workpieces, and at the same time has the characteristics of compact structure, applicability and high precision.

[0024] Embodiment 2:

[0025] On the basis of Example 1, Figure 1 As shown, the first clamping member, the second clamping member and the third clamping member are grooves arranged in parallel.

[0028] On the basis of Example 1, Figure 5 As shown, the first clamping member is a first groove 52 , the second clamping member is a second groove 53 , the first groove 52 and the second groove 53 are arranged in parallel, and the third clamping member is an arc-shaped clamping member 51 for matching with the arc-shaped groove 33 arranged on the side of the positioning plate 3 .

[0029] The side walls of the bottom plate 1 and the loading plate 2 are respectively provided with fixing holes (ie, the first fixing hole 12 and the second fixing hole 23 ), and the first groove 52 and the second groove 53 are respectively provided with mounting holes matching the fixing holes.

[0030] The fixture is placed flat on the work surface. First, the base plate 1, the carrier plate 2 and the support plate 5 are assembled. In order to prevent relative displacement between the base plate 1 and the carrier plate 2, a groove of the support plate 5 is set. The second groove 53 and the base plate 1 are engaged and limited, and the first groove 52 and the carrier plate 2 are engaged and limited. After being limited, they can be fastened by a detachable screw 4. Then, the lead wire at the lower end of the workpiece to be welded passes through the large circular hole (i.e., the second through hole 21) of the carrier plate 2 until it reaches the small circular hole (i.e., the first through hole 13) of the base plate 1. The workpieces to be welded are placed on the fixture in turn. After all the assembly on the carrier plate is completed, the lead wire at the upper end of the workpiece passes through the small circular hole (the third through hole 31) on the positioning plate 3, and the positioning plate 3 is covered. The semi-cylinder (i.e., the arc-shaped clamping member 51) above the support plate 5 is engaged and positioned with the groove on the edge of the positioning plate 3 (i.e., the arc-shaped groove 33).
