[0032] Reference below Figures 1-4 The welding jig pressing structure according to the embodiment of the present invention is described.
[0033] like Figures 1-4 As shown, the welding jig clamping structure includes a jig body 100 and an elastic clamping portion 200. Specifically, a plurality of clamping blocks 110 are provided on one side of the jig body 100 for compacting the component 2, and the clamping blocks 110 extend upward perpendicular to the end surface of the jig body 100. The setting position and number of the clamping blocks 110 are set according to the position of the component 2 and the number of the components 2 on the product 1. The clamping blocks 110 are integrally formed with the jig body 100 to ensure that the position of the clamping blocks 110 is not offset, and the shape of the jig body 100 is adjusted according to the layout of the components 2 on the surface of the product 1. In this embodiment, the jig body 100 adopts an L-shaped structure, and four groups of clamping blocks 110 are provided, corresponding to the positions of the components 2 at four places of the product 1.
[0034] Four groups of elastic pressing parts 200 are provided corresponding to the pressing blocks 110, and the elastic pressing parts 200 are respectively provided in the pressing blocks 110. The elastic pressing parts 200 include pressing balls 210 and elastic members (not shown in the drawings). When the jig body 100 presses the product 1, the elastic member pushes the pressing balls 210 to press the components 2 on the product 1. Specifically, after the positions of the components 2 on the product 1 are arranged, when the jig body 100 presses down from the top of the product 1 to the components 2, the pressing balls 210 abut against the surface of the components 2 and are compressed into the pressing blocks 110. At this time, the elastic member is in a compressed state. After each pressing block 110 is fitted with each component 2, the pressing balls 210 are pushed toward the surface of the component 2 under the elastic action of the elastic member, and the position of the component 2 is further compacted by the pressing balls 210.
[0035] Existing fixtures typically rely on a compression block 110 to compact component 2. However, if a gap exists between the compression block 110 and component 2 due to machining or measurement errors, the compression block 110 will be unable to adhere to the surface of component 2 and exert pressure on it. This can cause component 2 to shift or loosen during the fixation process, affecting the compaction efficiency. Therefore, existing fixtures require more precise machining processes and rigorous measurement methods, which imposes high precision requirements and increases manufacturing costs.
[0036] The welding jig clamping structure of the present invention utilizes an elastic clamping portion 200 installed between the jig body 100 and the clamping block 110, and uses the elastic member to push the clamping ball 210 to compensate for the clamping of the component 2. The elastic member is made of a metal spring, which has a stronger elastic force and can push the clamping ball 210 to compact the component 2 on the product 1. The welding jig clamping structure of the present invention uses the elastic clamping portion 200 to perform a secondary compaction on the component 2 on the product 1. The elastic force of the elastic member effectively compensates for the compaction gap caused by the machining accuracy of the clamping block 110 and the height of the component 2, thereby improving the compaction effect of the jig body 100.
[0037] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a pressing groove 111 is provided on the surface of the pressing block 110, and the elastic pressing portion 200 is installed in the pressing groove 111. Specifically, the pressing groove 111 is drilled from one side of the jig body 100 to the pressing block 110. After the elastic pressing portion 200 is installed in the pressing groove 111, the drilled position of the jig body 100 is blocked, so that the elastic pressing portion 200 can move in the pressing groove 111 without being separated.
[0038] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the pressing ball 210 is disposed in the pressing groove 111 near one end of the end surface of the pressing block 110. One end of the elastic member abuts the bottom of the pressing groove 111, and the other end abuts the pressing ball 210. Specifically, when the pressing ball 210 retreats into the pressing groove 111, the elastic member is in a compressed state. At this time, the pressing ball 210 is pushed outward by the elastic force of the elastic member, thereby applying downward pressure to the surface of the pressing block 110.
[0039] Furthermore, if Figure 1 and Figure 3 As shown, the diameter of the compression groove 111 near the end surface of the compression block 110 is smaller than the diameter of the compression ball 210, and the compression ball 210 is confined in the compression groove 111. By narrowing the diameter of the opening of the compression groove 111, the compression ball 210 can be effectively prevented from escaping from the compression groove 111, thereby improving the structural installation stability of the elastic compression part 200.
[0040] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the pressing groove 111 is provided in the middle area of the pressing block 110. Specifically, the pressing groove 111 is provided in the middle so that the force applied to the component 2 is more uniform when the elastic pressing portion 200 applies pressure to the component 2.
[0041] Furthermore, the surface of the pressing ball 210 is coated with a rubber layer. Specifically, when the pressing ball 210 contacts the surface of the component 2, the rubber layer on the surface of the pressing ball 210 deforms first, thereby preventing the pressing ball 210 from rigidly contacting the surface of the component 2 and causing damage to the surface of the component 2.
[0042] In some embodiments of the present invention, the thickness of the compression block 110 ranges from 3 mm to 9 mm. Specifically, if the heights of components 2 on product 1 are inconsistent, the thickness of the compression block 110 of the jig body 100 can be adjusted based on the height of the components 2. Maintaining a high degree of fit between the compression blocks 110 of the jig body 100 and the components 2 of product 1 requires high machining precision. The elastic compression portion 200 of this embodiment effectively addresses the issues associated with machining precision and tolerances, providing secondary tolerance compensation through the elastic compression portion 200, thereby improving the jig's compaction effect.
[0043] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the jig body 100 is provided with a plurality of hollow holes 120 , which pass through the jig body 100 to reduce the weight of the jig body 100 .
[0044] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the fixture body 100 is provided with at least two positioning holes 130 , and the positioning holes 130 are used to assist the pressing block 110 in aligning with the component 2 on the product 1 .
