In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] The present application embodiment discloses an auxiliary mounting assembly for a printed circuit board, referring to Figure 1-3 , including a bracket 1, two sliders 2 are slidably connected to the inner walls on the left and right sides of the bracket 1, the four sliders 2 are divided into two groups and each group of sliders 2 is fixedly connected to a cross bar 3, the outer sides of the two cross bars 3 are slidably connected to two cross blocks 4, and the top sides of the four cross blocks 4 are fixedly connected to a tooling rod 5; by setting the cross bar 3 and the cross block 4, the front and rear mobility of the cross bar 3 is combined with the left and right mobility of the cross block 4 so that the tooling rod 5 can be adjusted according to printed circuit boards of different sizes. When the positions of the four tooling rods 5 are adjusted, the printed circuit boards to be installed and the matching shells are respectively mounted on the tooling rods 5. At this time, when screws are used to tighten, the misalignment of the channels can be effectively avoided, thereby avoiding the need for correction, avoiding waste of time, and improving installation efficiency.

[0021] In the present application, one side of the four cross blocks 4 is threadedly connected with a locking bolt 6, and the four locking bolts 6 are respectively in contact with the outer sides of the two cross bars 3; by setting the locking bolts 6, when the position of the tooling rod 5 is determined, the locking bolts 6 are turned to squeeze the cross bar 3, so that the cross block 4 can be locked, effectively preventing the tooling rod 5 installed on the cross block 4 from being displaced.

[0022] In the present application, limit grooves are provided on the inner walls on the left and right sides of the bracket 1, and the inner walls of the two limit grooves are slidably connected to two limit blocks, and the four limit blocks are fixedly connected to one side of the four sliders 2 respectively; by setting the limit grooves and the limit blocks, when the slider 2 moves, the limit grooves and the limit blocks cooperate, so that the slider 2 can maintain horizontal movement to avoid deviation.

[0023] In the present application, rubber pads 7 are fixedly connected to the tops of both sides of the bracket 1; by providing the rubber pads 7, when the printed circuit board is mounted on the tooling rod 5, the printed circuit board will contact the top side of the bracket 1. At this time, the rubber pads 7 can be used to prevent scratches on the surface of the printed circuit board.

[0024] In the present application, two rolling grooves are provided on the bottom sides of the four cross blocks 4, and the inner walls of the eight rolling grooves are movably mounted with balls 8; by providing the balls 8, the friction between the cross block 4 and the bracket 1 can be reduced when the cross block 4 moves, thereby improving the smoothness of movement. At the same time, the bracket 1 can limit the cross block 4 to prevent the cross block 4 from flipping over during movement and causing the tooling rod 5 to shift.

[0025] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0026] The implementation principle of an auxiliary installation assembly for a printed circuit board in the embodiment of the present application is as follows: positioning holes are reserved in advance during the production of the printed circuit board to facilitate later assembly. After manually adjusting the cross bar 3 forward and backward, the position of the cross block 4 in the left and right directions is adjusted. The front and back mobility of the cross bar 3 is combined with the left and right mobility of the cross block 4 so that the tooling rod 5 can be adjusted according to the positions of printed circuit boards of different sizes. When the positions of the four tooling rods 5 are adjusted, the printed circuit boards to be installed and the matching housings are respectively mounted on the tooling rods 5. At this time, when screws are used to tighten, misalignment of the channels can be effectively avoided, thereby avoiding the need for correction, avoiding wasting time, and improving installation efficiency. After the position of 5 is determined, the locking bolt 6 is turned to squeeze the cross bar 3, so that the cross block 4 can be locked, effectively preventing the tooling rod 5 installed on the cross block 4 from being displaced. When the slider 2 moves, the limit groove and the limit block cooperate, so that the slider 2 can keep moving in the horizontal direction to avoid deviation. When the printed circuit board is mounted on the tooling rod 5, the printed circuit board will contact the top side of the bracket 1. At this time, the rubber pad 7 can be used to prevent scratches on the surface of the printed circuit board. When the cross block 4 moves, the ball 8 can be used to reduce the friction between the bracket 1 and the bracket 1, thereby improving the smoothness of the movement. At the same time, the bracket 1 can limit the cross block 4 to prevent the cross block 4 from flipping over during movement, causing the tooling rod 5 to deviate.
