Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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. Specific embodiment 1

[0031] See also Figure 1-3The utility model is a spot welding auxiliary device for electronic components, including a clamping and adjusting component 1, which includes a fixing plate 107, a mounting plate 105 is arranged above the fixing plate 107, a threaded rod 108 is threadedly connected at the middle position of the fixing plate 107, and the threaded rod 108 is rotatably connected to the mounting plate 105 through a bearing, a connecting rod 1053 is fixed to the upper wall of the mounting plate 105, and a rotating block 106 is rotatably connected to the outer portion of the connecting rod 1053 through a bearing, and a horizontal plate 103 is arranged above the rotating block 106, and the horizontal plate 103 is preferably circularly arranged, and rubber strips 102 are symmetrically arranged on the left and right sides of the upper wall of the horizontal plate 103, and the mounting plate 105 is driven to move by the rotation of the threaded rod 108, so as to finally adjust the height of the circuit board, and the angle of the circuit board is adjusted by the rotation of the rotating block 106 and the connecting rod 1053.

[0032] Specifically, legs 1071 are fixed at the four corners of the lower wall of the fixed plate 107, and the lower ends of the legs 1071 can be fixed on the mounting platform. A screw block 1081 is fixed to the lower end of the threaded rod 108, and the outer peripheral wall of the screw block 1081 is provided with anti-slip grooves to increase the friction between the hand and the screw block 1081 when the screw block 1081 is rotated.

[0033] Guide rods 1072 are fixed at the four corners of the upper wall of the fixing plate 107, and guide sleeves 1051 are fixed to the outer side of the guide rods 1072 corresponding to the lower wall of the mounting plate 105, and the guide rods 1072 and the guide sleeves 1051 are matched with each other in a clearance. The above arrangement allows the mounting plate 105 to only move up and down, while preventing the mounting plate 105 from tilting due to lateral force.

[0034] The rotating block 106 is circular in design, and a friction block 104 is provided on the outer peripheral wall on the left side of the rotating block 106. The friction block 104 is made of high friction material, and the friction force when the friction block 104 and the rotating block 106 are in contact is used to increase the resistance when the horizontal plate 103 is rotated, so as to avoid the self-rotation of the horizontal plate 103. A horizontal bar 1041 is fixed to the left wall of the friction block 104, and an L-shaped plate 1052 is provided on the outside of the horizontal bar 1041, and the L-shaped plate 1052 is fixedly connected to the mounting plate 105 by bolts.

[0035] The outer part of the crossbar 1041 is sleeved with an elastic member 109, and the left and right ends of the elastic member 109 are respectively in contact with the corresponding L-shaped plate 1052 and the friction block 104, so that the friction block 104 is always in contact with the rotating block 106 to maintain friction.

[0036] A connecting plate 1061 is fixed to the upper wall of the rotating block 106, and the connecting plate 1061 is rotatably connected to the cross plate 103. The interior of the connecting plate 1061 is rotatably connected to the screw 101 through a bearing, and the thread directions of the outer peripheral walls on the left and right sides of the screw 101 are opposite. By operating the screw 101 to rotate, the two mounting plates 105 are driven to move closer to or away from each other, thereby realizing the clamping or release operation of the circuit board.

[0037] Protrusions 1011 are fixed on both ends of the screw 101, and the outer wall of the protrusion 1011 is provided with anti-slip grooves to increase the friction between the hand and the protrusion 1011 when operating the protrusion 1011. Air avoidance grooves 1031 are provided on the corresponding horizontal plates 103 above the left and right sides of the screw 101, and the convex plate 1022 is located inside the corresponding air avoidance groove 1031 and moves.

[0038] The left and right sides of the screw rod 101 are both threadedly connected with a convex plate 1022, and the convex plate 1022 passes through the corresponding air avoidance groove 1031. The convex plate 1022 is fixedly connected to the rubber strip 102. A card slot 1021 is provided on the inner side of the rubber strip 102. When the circuit board is clamped and fixed, the two ends of the circuit board are located in the corresponding card slots 1021.

[0039] The operation process of this embodiment is as follows: during installation, the bottom of the support leg 1071 is fixed to the installation platform, and then the operator rotates the threaded rod 108 by twisting the screw block 1081. When the threaded rod 108 rotates, its own height changes, driving the mounting plate 105 to move up and down accordingly. At this time, the cross plate 103 moves up and down accordingly, so that the rubber strip 102 that clamps and fixes the circuit board moves to a suitable height. When installing the circuit board, the circuit board is placed at the horizontal height of the slot 1021, and the protrusion 1011 is operated to drive the screw rod 101 to rotate, so that the convex plate 1022 drives the corresponding rubber strip 102 to approach each other until the two ends of the circuit board are located in the slot 1021 and the rubber strip 102 clamps and fixes the circuit board. When adjusting the angle of the circuit board, the cross plate 103 can be rotated. Specific embodiment 2
