Description

Technical Field

[0001] This utility model relates to the field of fixing electronic components on a control motherboard, and in particular to a positioning fixture for inserting electronic components on a control motherboard. Background Technology

[0002] The control board is generally composed of a circuit board and electronic components soldered onto it. During soldering, the circuit board is often placed directly on the workbench, and then the electronic components are inserted and soldered. While this method is convenient, accidental contact by the operator can cause the circuit board to move, leading to incorrect soldering. When using positioning fixtures to fix the circuit board, the varying sizes and specifications of different circuit boards present a challenge: ensuring the stability of the fixation while also ensuring the applicability of the positioning fixture becomes a critical issue.

End horizontal holes are opened at both ends of the movable horizontal plate, and the end rod passes through the end horizontal holes.

[0005] Furthermore, the inner end of the rotating clamp has an arc-shaped structure.

[0006] Furthermore, there is an angle between the length direction of the rotating clamp and the length direction of the swing arm, and the angle is obtuse.

[0007] Furthermore, the outer end of the connecting rod is connected to a boss by a thread, the outer end of the boss is rotatably provided with an inner shaft, the inner shaft is provided with a waist-shaped plate, and a pressure plate is sleeved on the connecting rod located on the same movable block, the inner end of the waist-shaped plate acts on the outer wall of the pressure plate.

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0011] Figure 1 A three-dimensional structure of one embodiment is shown. Figure 1 .

[0012] Figure 2 A magnified view of point A is shown.

[0013] Figure 3 A three-dimensional structure of one embodiment is shown. Figure 2 . Detailed Implementation

[0014] like Figures 1-3 As shown, a positioning fixture for inserting electronic components on a control motherboard includes a placement plate 1, on which a pair of parallel transverse holes 10 are provided, and a support leg 2 is fixed to the placement plate 1 by screws, and the support leg 2 is mounted and fixed on a worktable.

[0015] A pair of lower horizontal plates 3 are fixed to the lower wall of the placement plate 1 by screws. A pair of guide holes 30 are provided on the lower horizontal plates 3. The length direction of the guide holes 30 is parallel to the length direction of the transverse hole 10. Movable blocks 31 are respectively provided on the outer sides of both ends of the lower horizontal plates 3. Multiple connecting rods 32 are connected to the movable blocks 31 by threads. The connecting rods 32 pass through the guide holes 30. The position of the movable blocks 31 can be adjusted by the connecting rods 32. During adjustment, it is necessary to ensure that the moving distance of the movable blocks 31 is equal as much as possible. A rotating shaft 37 is rotatably provided on the movable block 31. A swing arm 38 is fixed to the lower end of the rotating shaft 37 by screws. An end rod 52 is welded to the outer end of the swing arm 38. The rotating shaft 37 passes through the transverse hole 10. A rotating clamping plate 39 is fixed to the upper end of the rotating shaft 37 by screws. The inner end of the rotating clamping plate 39 has an arc-shaped structure. The arc-shaped structure design can avoid damage to both sides of the circuit board when the rotating clamping plate 39 is clamped. There is an obtuse angle between the length direction of the rotating clamp 39 and the length direction of the swing arm 38. When positioning the circuit board, the rotation of the rotating arm 38 will drive the rotating clamp 39 on it to rotate. The inner end of the rotating clamp 39 will act on both sides of the circuit board, thereby achieving the purpose of positioning the circuit board.

[0016] A pair of inner seats 45 are screwed onto the lower wall of the placement plate 1. An extended guide rod 47 is threaded onto the inner seat 45, and a T-shaped seat 46 is fitted onto the extended guide rod 47. An inner pressure screw 48 is threaded onto the T-shaped seat 46, and an end cap 49 is provided at the outer end of the inner pressure screw 48. A movable horizontal plate 50 is screwed onto the lower wall of the T-shaped seat 46. End horizontal holes 51 are respectively opened at both ends of the movable horizontal plate 50, and an end rod 52 passes through the end horizontal holes 51. Rotation of the inner pressure screw 48 drives the movable horizontal plate 50 to move, which in turn moves the end horizontal holes 51, thereby moving the end rod 52. The movement of the end rod 52 then causes the swing arm 38 to rotate. This achieves rapid positioning of the circuit board, and after fixing, the stability of the circuit board positioning is ensured by using the inner pressure screw 48 as the driving method.

[0017] In this embodiment, when positioning the circuit board, the operator adjusts the position of the movable block 31 according to the size specifications of the circuit board. After adjustment, the operator rotates the inner pressure screw 48. The rotation of the inner pressure screw 48 will drive the T-shaped seat 46 to move inward. The inward movement of the T-shaped seat 46 will drive the moving horizontal plate 50 on it to move inward. The inward movement of the moving horizontal plate 50 will cause the end horizontal hole 51 on it to act on the end rod 52, thereby causing the swing arm 38 to rotate. The rotation of the swing arm 38 will drive the rotating clamp 39 on it to rotate through the rotating shaft 37, and finally act on both sides of the circuit board through the rotating clamp 39, thereby achieving the purpose of positioning the circuit board. After the circuit board is fixed, the electronic components are inserted.

[0018] In some embodiments, in order to facilitate quick adjustment and fixation of the position of the movable block 31, a boss 33 is threadedly connected to the outer end of the connecting rod 32. An inner shaft 34 is rotatably provided at the outer end of the boss 33. A waist-shaped plate 35 is provided on the inner shaft 34. A pressure plate 36 is sleeved on the connecting rod 32 located on the same movable block 31. The inner end of the waist-shaped plate 35 acts on the outer wall of the pressure plate 36.

[0019] In this embodiment, when locking the position of the movable block 31, the operator rotates the waist-shaped plate 35. The rotation of the waist-shaped plate 35 will cause the pressure plate 36 on it to abut against the lower horizontal plate 3, thereby achieving the purpose of locking the position of the movable block 31.

[0020] In some embodiments, in order to ensure the stability of the circuit board positioning, an upper extension post 40 is welded to the inner end of the rotating clamping plate 39. A rotation notch 41 is provided on the upper extension post 40. A connecting pin 42 is rotatably provided on the upper extension post 40. A clamping plate 43 is provided on the connecting pin 42. The clamping plate 43 is located inside the rotation notch 41. A top spring 44 is provided at the outer end of the clamping plate 43. The lower end of the top spring 44 is fixed to the rotating clamping plate 39.

[0021] In this embodiment, when clamping the circuit board, the inner end of the clamping plate 43 needs to be rotated upward first, and then it can be released after the circuit board is placed, so that the circuit board can be stably fixed.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
