[0025] The following further elaborates on the present utility model in conjunction with the accompanying drawings and the detailed implementation mode.
[0026] The present utility model discloses a circuit board welding bracket, and the main structural components include: a table clamp base 1, a main body frame 3, a sliding arm 5, and a circuit board jaw 6.
[0027] Among them, the table clamp base 1 realizes the clamping and fixing of the entire circuit board welding bracket at the tabletop. At the same time, the table clamp base 1 serves as a bottom support for the setting of other components such as the main body frame 3.
[0028] The structural setting of the table clamp base 1 is specifically as Figure 4 shown, including a clamping bracket 11 and an adjusting stud 15. The top wall of the clamping bracket 11 extends horizontally forward and is used for the fixed setting of the support column 2. The extended top wall structure enables the entire circuit board welding bracket not to be too close to the table edge after being clamped and fixed.
[0029] The bottom wall of the clamping bracket 11 is of an ear type structure, provided with a threaded hole adapted to the adjusting stud 15. The adjusting stud 15 is installed from this threaded hole and passes upward to be connected with a suction cup 14. The suction cup 14 and the top wall of the clamping bracket 11 jointly form the clamping space of the table clamp; correspondingly, a rotating handle 13 is provided at the bottom of the adjusting stud 15.
[0030] Thus, rotating the rotating handle 13 causes the suction cup 14 to press upward against the table edge of the workbench, and the top wall of the clamping bracket 11 presses against the upper side of the table edge of the workbench. The threaded structure realizes locking, thereby realizing the use and installation of the table clamp base 1.
[0031] The main body frame 3 presents an H-shaped structural feature, is supported above the table clamp base 1 through the support column 2, and the main body frame 3 is hinged to the support column 2; specifically, the hinge structure setting is as follows: also as Figure 4As shown in the figure, a hinge ear 8 is fixed to the top end of the support column 2, and a hinge head adapted to the hinge ear 8 is fixed below the middle frame 32 of the main body frame 3. The hinge head is inserted into the hinge ear 8, and an adjusting butterfly nut assembly is assembled together with the hinge ear 8. The adjusting butterfly nut assembly specifically refers to a hinge shaft and a butterfly nut. The hinge shaft passes through the hinge ear and the hinge head and is locked, and is threadedly connected to the butterfly nut at one end. Thus, loosening the butterfly nut can realize the angle adjustment of the main body frame 3, and tightening the butterfly nut can realize the locking and maintenance of the currently adjusted angle. The main body frame 3 is set to be angle-adjustable, which is convenient for selecting a suitable working angle.
[0032] At the same time, the main body frame 3 also provides structural support for the sliding of the sliding arm 5. The sliding arm is arranged at the vacant positions at both ends of the main body frame 3. The specific structural arrangement is as follows: Figure 1 and Figure 2 As shown in the figure, a chute 33 is opened on the inner side of the frame 31 of the main body frame 3, and an adjusting slot hole 34 is opened on the top end surface; both ends of the sliding arm 5 are respectively inserted into the chute 33, and threaded holes are opened at both ends of the sliding arm 5; one threaded hole corresponds to one adjusting slot hole 34, and a first adjusting member 4 is assembled together between the corresponding threaded hole and the adjusting slot hole 34. The first adjusting member 4 refers to a screw rod structure with a screwing nut. After the screw rod passes through the first adjusting slot hole 34, it is threadedly connected to the threaded hole on the sliding arm 5.
[0033] Thus, the chute 33 provides guidance for the sliding movement of the sliding arm 5, and the adjusting slot hole 34 limits the position where the sliding arm 5 can slide; when the first adjusting member 4 is loosened, the sliding arm 5 is manually slid and adjusted; when the first adjusting member 4 is tightened, the sliding arm 5 is positioned at the currently adjusted position.
[0034] The circuit board gripper 6 is arranged on the sliding arm 5 and can move synchronously with the corresponding sliding arm. One sliding arm 5 is provided with one circuit board gripper 6, so that the two circuit board grippers are symmetrically distributed, so that the two groups of circuit board grippers 6 are jointly used for clamping the circuit board.
[0035] Considering that the thicknesses of different circuit boards are inconsistent, the circuit board gripper 6 can also be designed to clamp circuit boards of various thicknesses. Specifically, as follows: Figure 3 As shown in the figure, the circuit board gripper 6 includes a gripper main body 61 and a second adjusting member 63; the gripper main body 61 forms a clamping cavity 62, and clamping plates 64 are distributed in the clamping cavity 62; the second adjusting member 63 is assembled at the threaded hole at the top of the gripper main body 61 and penetrates downward into the clamping cavity 62 to connect the clamping plates 64.
[0036] For the second adjusting member 63, a screw rod structure with a screwed nut is also adopted. After the screw rod is threadedly connected to the threaded hole of the jaw body 61, it is connected downward to the clamping plate 64. Thus, by turning the second adjusting member 63, the screw rod of the second adjusting member moves up and down, thereby driving the clamping plate 64 to rotate and move up and down, realizing the adjustment of the size of the clamping space for clamping the circuit board. To prevent the clamping plate 64 from wearing the circuit board when clamping the circuit board and avoid electrical conduction, a rubber insulating pad 65 is fixedly laid on the surface of the clamping plate 64.
[0037] It can be seen from this that for the circuit board welding bracket disclosed in the present utility model, firstly, a table clamp base is designed. By using the table clamp base, the circuit board welding bracket can be fixed at the edge position of the workbench, so that the entire circuit board welding bracket has a stable structure during use, avoiding situations such as the bracket tipping over or shifting, improving safety and helping to maintain the normal progress of the spot welding operation. Secondly, an H-shaped main frame structure is designed. Based on the main frame, a sliding arm is arranged. The circuit board jaws can move along with the sliding arm, and thus the distance between the two circuit board jaws for cooperative clamping can be adjusted, so that the circuit board welding bracket of the present utility model can be used for welding and clamping circuit boards of different sizes. Furthermore, the clamping space of the circuit board jaws can be adjusted, so that the circuit board welding bracket of the present utility model can be used for welding and clamping circuit boards of different thicknesses. Combining size adaptation and clamping adjustment, the circuit board welding bracket disclosed in the present novelty has more flexible and extensive applicability.
[0038] The above embodiments are not limitations on the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model also fall within the protection scope of the present utility model.
