DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below. Figures 1 to 5 The embodiment of the present invention provides a universal jig structure for passing through a furnace and a manufacturing method thereof. The universal jig for passing through a furnace comprises: a jig base 100, a jig bottom plate 200, a slider 300 and a fixing device 400. The jig base 100 has a first slider groove 110 and a second slider groove 120, and the first slider groove 110 and the second slider groove 120 are respectively located on different sides of the jig base 100; the jig bottom plate 200 has a first fixing groove 210 and a second fixing groove 220 that can correspond to the first slider groove 110 and the second slider groove 120; the slider 300 can be clamped in the first slider groove 110 and the second slider groove 120, and the slider 300 is provided with a positioning pin 310 and a screw hole 320; the fixing device 400 comprises a bottom screw 410, and the bottom screw 410 can pass through the screw hole 320 and be tightened with a nut 420. By setting slider grooves at different positions on the jig base 100 and setting fixed grooves at corresponding positions on the jig bottom plate 200, the slider 300 can move freely in the slider groove, and different products can be quickly positioned and placed, so that the jig can adapt to products of various specifications and sizes, thereby improving the versatility and flexibility of the jig and effectively solving the problems of high cost and low efficiency of traditional jigs.

[0032] Furthermore, the present invention does not limit the specific positions of the first slider groove 110 and the second slider groove 120. Figure 2The first slider groove 110 and the second slider groove 120 are respectively located on two sides of the fixture base 100 that are perpendicular to each other, so that the slider 300 can be positioned in two perpendicular directions. Of course, the present invention does not limit the specific shapes of the first fixing groove 210 and the second fixing groove 220. Preferably, refer to Figure 3 , the first fixed groove 210 is not connected inside. This structure means that the slider 300 can be positioned in different sections instead of being able to move along a single path. This can provide more diverse positioning options to meet the needs of products of different sizes or shapes. Similarly, the second fixed groove 220 is also not connected inside. Therefore, the number and position of the sliders 300 can be adjusted according to the specific needs of different products. Of course, the present invention does not limit the number of segments of the first fixed groove 210 and the second fixed groove 220. Preferably, the first fixed groove 210 can be divided into two independent grooves, each of which can be placed in a slider 300; the second fixed groove 220 can be divided into two independent grooves, each of which can be placed in a slider 300. The two sliders 300 form a group, and each side can be provided with a group of sliders 300 for movement. This multi-dimensional positioning capability greatly improves the flexibility of the fixture and can be used for more products of different shapes and sizes. For example, for rectangular or square products 600, precise adjustments can be made in the horizontal and vertical directions to ensure accurate positioning of the product. Reference Figure 1 and Figure 4 This fixture structure can adapt to more complex geometric shapes and layout requirements. The product 600 to be processed is fixed and limited by the positioning pin 310 and the fixture. Furthermore, the fixing device 400 includes a bottom screw 410 and a nut 420. Of course, the present invention does not limit the specific number of the bottom screw 410 and the nut 420. Preferably, the number of nuts 420 is two, which are fixed to the two ends of the screw 410 respectively.

[0033] Furthermore, refer to Figure 2 , the four corners of the fixture base 100 are provided with limit posts 130; Figure 3, the four corners of the jig base 200 are provided with limiting holes 230, and the limiting columns 130 can be inserted into the limiting holes 230. By setting the limiting columns 130 on the jig base 100, setting the limiting holes 230 on the jig base 200, and snapping the limiting columns 130 into the limiting holes 230, the jig base 100 and the jig base 200 are fixedly connected, ensuring the overall stability and reliability of the entire jig. Furthermore, a contraction portion 140 is provided on the side of the jig base 100, and the contraction portion 140 is concave to the side to facilitate the removal of the jig. Of course, the present invention does not limit the specific structure of the contraction portion 140. Preferably, the edge of the contraction portion 140 is recessed into the side of the jig base 100, so that the operator can more easily carry and operate the jig, thereby improving work efficiency. Furthermore, a support foot 150 is provided at the bottom of the fixture base 100, and the support foot 150 is made of plastic material, and the support foot 150 is used to increase the height of the fixture base 100. This design increases the height of the fixture base 100, which is convenient for operation and heat dissipation. At the same time, the use of plastic material also reduces the weight of the fixture and improves the convenience of transportation. Furthermore, a plurality of air holes 240 are provided on the fixture base 200, and the plurality of air holes 240 are evenly distributed. The air holes 240 help to improve the heat dissipation performance of the fixture base 200, avoid local overheating, and improve the welding quality during operation. In addition, the even distribution of the air holes 240 helps to form an air flow path and improve the heat dissipation efficiency. Furthermore, when the slider 300 is clamped in the first slider groove 110 and the second slider groove 120, the end face of the slider 300 is located in the same plane as the end face of the fixture base 100. This design ensures the smooth movement of the slider 300 in the slot, avoids jamming and wear, and improves the service life and smoothness of operation of the slider 300. Of course, the present invention does not limit the specific material of the jig base 100 and the jig bottom plate 200. Preferably, the jig base 100 is made of plastic material, and the jig bottom plate 200 is made of aluminum alloy. Plastic material has excellent processing performance and lightweight characteristics, which reduces the manufacturing cost and handling difficulty of the jig; aluminum alloy material has high temperature resistance, high strength and good thermal conductivity, can withstand welding operations in high temperature environments, and improves the durability and reliability of the jig.

[0034] Furthermore, the present invention also proposes a method for manufacturing a universal fixture structure for furnace passing, including the fixture structure mentioned above, referring to Figure 5, specifically including the following steps: S1, selecting materials for the jig base plate 200 and the jig base 100; S2, designing grooves on the jig base plate 200 and the jig base 100; S3, designing a movable slider 300; S4, assembling the movable slider 300 designed in step S3 with the jig base plate 200 and the jig base 100 in step S2. Further, in step S1, suitable materials are selected to construct the jig base 100 and the jig bottom plate 200 to ensure that they have the required physical and chemical properties, such as high temperature resistance, light weight, high strength and easy processing. In step S2, precise first slider grooves 110 and second slider grooves 120 and limiting holes 230 are opened on the jig base 100 and the jig bottom plate 200 to facilitate the subsequent installation and fixation of the slider 300. Specifically, the first slider grooves 110 and the second slider grooves 120 are respectively opened on the jig base 100 to ensure that the groove width is moderate, so that the slider 300 can slide smoothly without being too loose. At the same time, limiting columns 130 are set at the four corners of the jig base 100, and the side edges are retracted to form a contraction portion 140 to facilitate the removal of the jig. Further, support feet 150 are installed around the bottom. The support feet 150 are made of plastic material to increase the height of the jig and provide stable support. Furthermore, step S2 also includes opening a first fixing groove 210 and a second fixing groove 220 on the jig base 100 corresponding to the first slider groove 110 and the second slider groove 120 on the jig base 100 to ensure that the slider 300 can be accurately embedded; and limiting holes 230 are set at the four corners of the jig base 200 to match the limiting columns 130 of the jig base 100 to ensure that the two are aligned. Furthermore, a plurality of evenly distributed air holes 240 are set on the jig base 200 to improve the heat conduction efficiency and heat dissipation effect.Further, in step S3, the purpose of designing a movable slider 300 is to design a slider 300 that can slide freely in the first slider groove 110 and the second slider groove 120 and can be firmly fixed by the fixing device 400 to adapt to the positioning requirements of shapes of different sizes and products 600. The design of the slider 300 needs to consider its length, thickness and surface smoothness to ensure that it can move smoothly in the first slider groove 110 and the second slider groove 120 without getting stuck; further, in step S4, all components are assembled into a completed universal jig structure for passing the furnace according to the design requirements to ensure that the connection between the components is stable and reliable. Of course, the present invention does not limit the specific assembly order. Preferably, the slider 300 is placed in the jig base 1 00, adjust the first slider groove 110 and the second slider groove 120 to the appropriate position; use the bottom screw 410 to pass through the screw hole 320 on the slider 300, and then select the nut 420 from the bottom, tighten the screw to fix the slider 300; copy the fixture base plate 200 on the fixture base 100, align the limiting hole 230 on the fixture base plate 200 with the limiting column 130 on the fixture base 100, and gently press down until the two are tightly combined; check whether the positioning pin 310 of the slider 300 is correctly inserted into the fixing groove on the base plate 200. After confirmation, you can proceed to the next step. According to actual production needs, repeat the above process to adjust the position of other sliders 300 to meet the positioning requirements of different types of products 600.
