Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0026] See also Figure 1-4 The utility model provides a technical solution: an electronic processing reflow soldering machine processing table, including a base 1, a positioning frame 2 is arranged on the top of the base 1, two fixing plates 7 are fixedly installed on both sides of the positioning frame 2, and fixing columns 8 are fixedly installed on the bottom of the four fixing plates 7. The bottoms of the four fixing columns 8 are all semicircular, and four mounting holes 16 are opened on the base 1. The four fixing columns 8 are respectively slidably connected inside the four mounting holes 16, and two inner card rods 10 are slidably connected on both sides of the base 1. The four fixing columns 8 extend to one end of the base 1. The four fixing columns 8 are all inclined, and the four fixing columns 8 are opened on the four fixing columns 8. The four inner card rods 10 are respectively slidably connected inside the four card slots 17. A connecting pull plate 9 is fixedly installed on the two inner card rods 10 on one side, and a tension spring 11 is fixedly installed between the connecting pull plate 9 and the base 1.

[0027] When the four inner card rods 10 are respectively coincident with the four card slots 17, the four inner card rods 10 are reset by the tension of the two tension springs 11, and the four inner card rods 10 are respectively stuck in the four card slots 17, completing the fixation of the four fixing columns 8 and the positioning frame 2, making it easy to fix the positioning frame 2, avoiding the difficulty of installation, and improving the speed of replacing the positioning frame 2.

[0028] The four inner clamping rods 10 are all fixedly mounted with limiting slide bars 18 . Four limiting slideways 19 are provided inside the base 1 . The four limiting slide bars 18 are slidably connected inside the four limiting slideways 19 .

[0029] By providing the limiting slide bar 18 and the limiting slideway 19 , it is convenient to limit the moving distance of the inner locking rod 10 .

[0030] The interior of the positioning frame 2 is slidably connected to two movable slide bars 4, and the opposite ends of the two movable slide bars 4 are fixedly installed with a clamping plate 3, and the opposite sides of the two movable slide bars 4 are fixedly installed with a connecting plate 6, and the two movable slide bars 4 extend to the outside of the positioning frame 2. One end is movably sleeved with a tension spring 5, and the opposite ends of the two tension springs 5 ​​are respectively fixedly connected to the two sides of the positioning frame 2, and the opposite ends of the two tension springs 5 ​​are respectively fixedly connected to the two connecting plates 6, and a fixed plate 12 is fixedly installed on the two connecting plates 6, and a toothed plate 13 is fixedly installed on the opposite side of the two fixed plates 12. One side of the positioning frame 2 is rotatably connected with a rotating shaft 15, and a gear 14 is fixedly sleeved on the rotating shaft 15, and the gear 14 is meshed with the two toothed plates 13.

[0031] Rotate the rotating shaft 15 so that the rotating shaft 15 drives the gear 14 to rotate, thereby causing the two tooth plates 13 and the two fixed plates 12 to move away from each other, thereby pushing the two connecting plates 6 to move away from each other, causing the two movable slide bars 4 to move outward inside the two positioning frames 2, stretching the two tension springs 5, and finally causing the two clamping plates 3 to move away from each other, placing the electronic board between the two clamping plates 3, and then no longer rotating the rotating shaft 15 so that the two movable slide bars 4 and the two clamping plates 3 are reset by the tension of the two tension springs 5, thereby causing the two clamping plates 3 to clamp the electronic board to prevent the electronic board from moving, thereby improving the fixing effect of the electronic board and improving the stability of the electronic board processing.

[0032] Working principle:

[0033] Pull the two connecting pull plates 9 to make the four inner card rods 10 slide inside the base 1, thereby stretching the two tension springs 11, and at the same time, the four inner card rods 10 will be disengaged from the inside of the four card slots 17, thereby releasing the fixation of the fixing column 8, and then removing the positioning frame 2 from the base 1. During installation, the four fixing columns 8 are inserted into the four mounting holes 16, and then the semicircularity of the lower ends of the four fixing columns 8 will squeeze the inclined surfaces of the four inner card rods 10 respectively, thereby moving the four inner card rods 10 and stretching the two tension springs 11. When the four inner card rods 10 coincide with the four card slots 17 respectively, the four inner card rods 10 will be reset by the tension of the two tension springs 11, and then the four inner card rods 10 will be respectively stuck into the inside of the four card slots 17, completing the fixation of the four fixing columns 8 and the positioning frame 2.

[0034] Rotate the rotating shaft 15 so that the rotating shaft 15 drives the gear 14 to rotate, thereby causing the two tooth plates 13 and the two fixed plates 12 to move away from each other, thereby pushing the two connecting plates 6 to move away from each other, causing the two movable slide bars 4 to move outward inside the two positioning frames 2, stretching the two tension springs 5, and finally causing the two clamping plates 3 to move away from each other, placing the electronic board between the two clamping plates 3, and then stopping rotating the rotating shaft 15, causing the two movable slide bars 4 and the two clamping plates 3 to be reset by the tension of the two tension springs 5, thereby causing the two clamping plates 3 to clamp the electronic board.
