Detailed Implementation

[0029] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0030] like Figure 2 As shown, this utility model provides a clamping device, comprising:

[0031] The support component 1, the rotating arm 2, and the lever 3 are rotatably connected to the support component 1. The rotating arm 2 rotates in a first plane, and the lever 3 rotates in a second plane perpendicular to the first plane. The lower end and the upper end of the rotating arm 2 form a moving end 4 and a pressing end 5, respectively. One side of the lever cooperates with the moving end 4, and the pressing end 5 can press the pressed component 12 by moving the moving end 4.

[0032] Specifically, to address the problem that existing clamping devices are large in size, occupy a lot of space, and are difficult to apply to different types of products when placed in welding equipment, the clamping device provided by this utility model uses the rotation of the lever 3 to press the lever end 4 of the rotating arm 2, causing the rotating arm 2 to rotate. The clamping end 5 of the rotating arm 2 then clamps the component 12 being clamped. When the support component 1 is installed on other components, the lever 3 can be positioned between the rotating arm 2 and the component being installed. Since the rotating arm 2 and the lever 3 rotate in mutually perpendicular first and second planes respectively, this layout is compact and saves space. Thus, when this clamping device is installed on the welding fixture, the overall size of the welding fixture is small, occupying less space, and it can accommodate larger products being welded in the welding equipment.

[0033] In this embodiment, one end of the lever 3 is hinged to the support member 1, the middle part of the lever 3 is used to contact the actuating end 4, and the other end of the lever 3 forms the operating end.

[0034] Optionally, the rotating arm 2 has an L-shaped structure, and the middle part of the rotating arm 2 is rotatably connected to the support component 1.

[0035] Specifically, the rotating arm 2 adopts an L-shaped structure, with a toggle end 4 and a clamping end 5 formed at its two ends respectively. When the lever 3 rotates and presses down on the toggle end 4, it will push the toggle end 4 outward, causing the rotating arm 2 to rotate, and then the clamping end 5 to move, which can clamp the clamped part 12.

[0036] Optionally, it also includes an elastic member 6, which is connected to the rotating arm 2 and the support member 1. The elastic member 6 can apply a spring force to the rotating arm 2 so that the rotating arm 2 rotates in the direction of releasing the pressure.

[0037] Specifically, under the elastic force of the elastic component 6, the rotating arm 2 tends to rotate in the direction of releasing the clamping. Once the lever 3 removes the pressure and limit on the actuating end 4, the rotating arm 2 automatically releases the clamping of the clamped component 12.

[0038] Optionally, the elastic component 6 is a tension spring, with its two ends connected to the rotating arm 2 and the support component 1, respectively.

[0039] Specifically, the two ends of the tension spring can be connected to the rotating arm 2 and the support component 1 respectively by a screw.

[0040] In this embodiment, the tension spring is in a pre-stretched state.

[0041] Optionally, a first groove 7 is provided on the top of the support component 1, the first groove 7 makes the support component 1 form a U-shaped structure, a part of the lever 3 is rotatably connected in the first groove 7, a second groove 8 is provided on one side of the groove wall of the first groove 7, and the actuating end 4 is rotatably connected in the second groove 8.

[0042] Specifically, such as Figure 3 As shown, the support component 1 can adopt a U-shaped support block. One end of the lever 3 can be rotatably connected to the first groove 7 through the first pin 9, and the other end of the lever 3 is exposed for easy operation. The middle part of the rotating arm 2 is rotatably connected to the second groove 8 through the second pin 10, so that its actuating end 4 is rotatably set in the second groove 8. When the other end of the lever 3 moves downward, the middle part of the lever 3 can push the actuating end 4 to move outward, thereby causing the rotating arm 2 to rotate, realizing the movement and pressing of the pressing end 5.

[0043] In this embodiment, the support component 1 has a mounting hole 11, which is used to install the clamping device on other components through a connector.

[0044] Specifically, the support component 1 can be connected to other components by screws, for example, to install the clamping device on a welding fixture.

[0045] Optionally, the pressing end 5 is detachably connected to a pressing member 12, one end of which is connected to the pressing end 5, and the other end of which is used to contact the pressed part.

[0046] Specifically, the clamping component 12 is used to contact the part being clamped, and the shape and material of the clamping component 12 can be set according to the structure of the part being clamped and the clamping requirements.

[0047] In this embodiment, the clamping component 12 is mounted on the clamping end 5 by screws.

[0048] Optionally, the clamping component 12 includes an elongated portion and a connecting portion, the connecting portion being connected to the middle of the elongated portion to form a T-shaped structure, and the elongated portion being used to contact the part being clamped.

[0049] Specifically, the connecting part connects the long strip to the pressing end 5, and the long strip presses the pressed part, thereby increasing the pressing area.

[0050] Optionally, the long strip is provided with limiting protrusions 13 at both ends on the side away from the connecting part, and the space between the two limiting protrusions 13 is used to accommodate solder wire or solder bar.

[0051] Specifically, the limiting space formed between the two limiting protrusions 13 can accommodate the solder wire or solder bar used during welding, which helps to improve the welding quality.

[0052] Optionally, the rotating arm 2 has an L-shaped structure. The actuating end 4 is provided with a first protrusion 14 on the side near the lever 3. One end of the first protrusion 14 is provided with a first guide slope 15. The lever 3 is provided with a second protrusion 16 on the side near the rotating arm 2. One end of the second protrusion 16 is provided with a second guide slope 17 that cooperates with the first guide slope 15.

[0053] Specifically, such as Figure 4 and Figure 5 As shown, the rotating arm 2 and the lever 3 are respectively provided with a first protrusion 14 and a second protrusion 16 on the side close to each other. The lever 3 pushes the rotating arm 2 outward through the mutual contact of the first protrusion 14 and the second protrusion 16, thereby causing the pressing end 5 to press the pressed part 12. The first guide slope 15 and the second guide slope 17 provided at the upper end of the first protrusion 14 and the lower end of the second protrusion 16 respectively can form a guide between the lever 3 and the rotating arm 2 when the operating end of the lever 3 moves downward, which facilitates the pressing operation.

[0054] like Figure 6 and Figure 7 As shown, this utility model also provides a welding fixture, including:

[0055] The top surface of the support component 18 is the support surface, which is used to support the PCB board 19 to be soldered.

[0056] The aforementioned clamping device has a support component 1 connected to one side of the bearing component 18, and a clamping end 5 used to clamp the PCB board 19.

[0057] Specifically, such as Figure 6 As shown, the PCB board 19 to be soldered is placed on the bearing surface of the bearing component 18. Before soldering the PCB board 19, it needs to be clamped and fixed. At this time, the operating end of the operating lever 3 moves downward, driving the rotating arm 2 to rotate through the lever 3, and using the clamping component 12 on the clamping end 5 to clamp the PCB board 19, as shown. Figure 7 As shown, when it is necessary to remove the PCB board 19, the operating end of the operating lever 3 is lifted upward, releasing the squeezing limit of the lever 3 on the lower end of the rotating arm 2, and at this time, under the action of the elastic component 6, the rotating arm 2 rotates, driving the pressing component 12 to lift up, releasing the pressing on the PCB board 19.

[0058] In summary, the welding fixture with the aforementioned clamping device has a compact structure and occupies very little space, whether the clamping device is clamping the PCB board 19 or the clamping device is open. This reduces the space occupied by the welding equipment and makes it suitable for welding larger PCB boards 19 in the welding equipment.

[0059] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
