Detailed Implementation

[0025] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 4 This utility model provides a universal jig structure for furnace reflow, including: 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, which are 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 correspond to the first slider groove 110 and the second slider groove 120. The slider 300 can be engaged with 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 includes a bottom screw 410, which can pass through the screw hole 320 and be tightened with a nut 420. By setting slider grooves at different positions on the fixture base 100 and setting fixed grooves at corresponding positions on the fixture base plate 200, the slider 300 can move freely in the slider grooves, enabling rapid positioning and placement of different products. This allows the fixture to adapt to products of various specifications and sizes, improving the versatility and flexibility of the fixture and effectively solving the problems of high cost and low efficiency of traditional fixtures.

[0026] Furthermore, this utility model does not limit the specific positions of the first slider groove 110 and the second slider groove 120. Preferably, referring to... Figure 2 The first slider groove 110 and the second slider groove 120 are respectively located on two mutually perpendicular sides of the fixture base 100, so that the slider 300 can be positioned in two mutually perpendicular directions. Of course, this utility model does not limit the specific shape of the first fixing groove 210 and the second fixing groove 220. Preferably, referring to Figure 3The first fixing groove 210 is internally disconnected. This structure means that the slider 300 can be positioned in different segments, rather than moving only along a single path. This provides more diverse positioning options to adapt to the needs of products of different sizes or shapes. Similarly, the second fixing groove 220 is also internally disconnected. Therefore, the number and position of the sliders 300 can be adjusted according to the specific needs of different products. Of course, this utility model does not limit the number of segments in the first fixing groove 210 and the second fixing groove 220. Preferably, the first fixing groove 210 can be divided into two independent grooves, each groove can hold one slider 300; the second fixing groove 220 can be divided into two independent grooves, each groove can hold one slider 300, with two sliders 300 forming a group, and a group of sliders 300 can be provided on each side for movement. This multi-dimensional positioning capability greatly improves the flexibility of the fixture, enabling the use of more products of different shapes and sizes. For example, for rectangular or square products 600, precise adjustments can be made in both the horizontal and vertical directions to ensure accurate product positioning. (Refer to...) 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 to the fixture by the positioning pin 310. Furthermore, the fixing device 400 includes a bottom screw 410 and a nut 420. Of course, this utility model does not limit the specific number of bottom screws 410 and nuts 420. Preferably, there are two nuts 420, which are fixed to both ends of the screw 410 respectively.

[0027] Furthermore, referring to Figure 2 Limiting posts 130 are set at the four corners of the fixture base 100; refer to Figure 3The fixture base plate 200 has limiting holes 230 at its four corners, and limiting posts 130 can be inserted into the limiting holes 230. By setting limiting posts 130 on the fixture base 100 and limiting holes 230 on the fixture base plate 200, and snapping the limiting posts 130 into the limiting holes 230, the fixture base 100 and the fixture base plate 200 are fixedly connected, ensuring the overall stability and reliability of the entire fixture. Furthermore, the fixture base 100 has a retractable part 140 on its side. The retractable part 140 is recessed to the side to facilitate the removal of the fixture. Of course, this utility model does not limit the specific structure of the retractable part 140. Preferably, the edge of the retractable part 140 is recessed into the side of the fixture base 100, so that the operator can more easily move and operate the fixture, improving work efficiency. Furthermore, the bottom of the fixture base 100 is provided with support feet 150, which are made of plastic material and are used to raise the fixture base 100. This design increases the height of the fixture base 100, facilitating operation and heat dissipation. At the same time, the use of plastic material reduces the weight of the fixture and improves the ease of handling. Furthermore, the fixture base plate 200 is provided with multiple ventilation holes 240, which are evenly distributed. The ventilation holes 240 help improve the heat dissipation performance of the fixture base plate 200, avoid local overheating, and improve welding quality during operation. In addition, the even distribution of the ventilation holes 240 helps to form an airflow path, improving heat dissipation efficiency. Furthermore, when the slider 300 is engaged with the first slider groove 110 and the second slider groove 120, the end face of the slider 300 and the end face of the fixture base 100 are located on the same plane. This design ensures smooth movement of the slider 300 within the slot, avoiding jamming and wear, and improving the service life and operational smoothness of the slider 300. Of course, this utility model does not limit the specific materials of the fixture base 100 and the fixture base plate 200. Preferably, the fixture base 100 is made of plastic, and the fixture base plate 200 is made of aluminum alloy. Plastic materials have excellent processing performance and lightweight characteristics, reducing the manufacturing cost and handling difficulty of the fixture; aluminum alloy materials have high temperature resistance, high strength, and good thermal conductivity, enabling them to withstand welding operations in high-temperature environments, thus improving the durability and reliability of the fixture.
