Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a welding rapid clamping device. Background Technology

[0002] The rapid welding push-tightening device is a mechanical clamping mechanism specifically designed for welding processes. Its core function is to quickly and stably push and fix the workpiece in place before or during welding, thereby effectively preventing misalignment caused by thermal deformation or external forces and improving welding efficiency and weld quality. This device typically adopts a combination structure of "toggle / linkage + drive + elastic reset," which can complete a series of "push-clamp-lock" actions in a short time.

[0003] However, most common welding quick-clamping devices currently available are equipped with only a single clamp, which can only hold one workpiece at a time, limiting the improvement of work efficiency. While setting multiple clamps on the same device can improve work efficiency, it will also increase the size of the equipment, making it inconvenient for transportation and storage. Utility Model Content

[0004] To address the problems mentioned above, this invention provides a rapid welding clamping device that can quickly fix multiple workpieces and is convenient for transportation and storage.

[0005] The solution adopted by this utility model to solve its technical problem is: a welding quick-pressing device, including a fixed base, a lever arm rotatably connected to the fixed base, a slide rod connected to the bottom of the lever arm through a connecting rod, the slide rod being rotatably connected to the fixed base, a secondary slide rod slidably connected to the side of the slide rod, and a pressure rod slidably connected inside both the slide rod and the secondary slide rod, with a positioning element provided at the top of the pressure rod.

[0006] Furthermore, the slide rod has a T-shaped groove on its side, and the auxiliary slide rod has a snap-fit ​​connector on one side, and the auxiliary slide rod is slidably connected to the inside of the T-shaped groove through the snap-fit ​​connector.

[0007] Furthermore, the T-shaped groove has an opening on the side away from the fixed seat, through which the auxiliary slide rod can slide out and disengage.

[0008] Furthermore, both the sliding rod and the auxiliary sliding rod have through grooves in their middle sections, and the pressure rod is disposed in the through grooves and can be adjusted longitudinally and laterally along the through grooves.

[0009] Furthermore, a pressure head is detachably provided at the bottom of the pressure rod, and the pressure head is made of an elastic material.

[0010] Furthermore, the pressure head is either a flat pressure head or a toothed pressure head.

[0011] In summary, the beneficial effects of this utility model are as follows:

[0012] 1. The welding quick-pressing device of this application is equipped with a slide bar and two auxiliary slide bars, which can simultaneously install multiple pressure bars and fix multiple workpieces;

[0013] 2. The auxiliary slide rod is slidably connected to both sides of the slide rod, and the pressure rod is set in the through groove of the auxiliary slide rod and the slide rod. The pressure rod can be adjusted longitudinally and laterally along the through groove. With the above design, the pressure rod can fix the workpiece in multiple positions, which is more flexible.

[0014] 3. An open structure is added to the side of the T-slot away from the fixed base, allowing the auxiliary slide rod to slide out or be installed directly along this open structure. The above design simplifies the assembly and disassembly process of the auxiliary slide rod. At the same time, when transportation or storage is required, the welding quick-pressing device can be quickly disassembled into a more compact form, improving portability.

[0015] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0020] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0021] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

[0022] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 3 As shown, a welding rapid pressing device includes a fixed base 1, which serves as the mounting base and force fulcrum for the entire device. A lever arm 2 is rotatably connected to the fixed base 1 via a rotating shaft. The operator can drive the entire pressing device by pressing down or lifting one end of the lever arm 2. A slide rod 3 is connected to the bottom of the lever arm 2 via a connecting rod 8. The slide rod 3 is rotatably connected to the fixed base 1. A secondary slide rod 4 is slidably connected to the side of the slide rod 3. Pressure rods 5 are slidably connected inside both the slide rod 3 and the secondary slide rod 4. A positioning element is provided at the top of the pressure rod 5.

[0024] It is important to note that, such as Figure 2 As shown, in this embodiment, the connecting rod 8 is fixedly connected to the slide rod 3 at the bottom by screws, and its top is rotatably connected to the lever arm 2 through a rotating shaft. This dual connection method together constitutes a stable toggle mechanism. When the lever arm 2 is pressed up or down, it will drive the slide rod 3 to rotate down or up, thereby pressing the pressure rod 5 against the workpiece surface or lifting it up.

[0025] In addition, such as Figure 2 The structure of the fixed base 1 includes a groove on its side wall that restricts the rotation direction of the connecting rod 8. A baffle is provided on the side of the groove facing the pressure rod 5, while the side away from the pressure rod 5 is the rotation side. Through this arrangement, the connecting rod 8, restricted by the baffle, can only move back and forth within the rotation side. Therefore, when the slide rod 3 is pressing and fixing the workpiece and is subjected to a reaction force, the connecting rod 8 cannot rotate towards the baffle side, thus preventing the slide rod 3 from lifting and providing a stable clamping force.

[0026] like Figure 1 As shown, the slide bar 3 in this embodiment has a T-shaped groove 31 on its side and a snap-fit ​​connector 41 on one side. The slide bar 4 is slidably connected to the inside of the T-shaped groove 31 through the snap-fit ​​connector 41 and is positioned inside the T-shaped groove 31 by bolts.

[0027] The T-slot 31 has an opening 311 on the side away from the fixed base 1, through which the auxiliary slide rod 4 can slide out and disengage. This design facilitates the removal of the auxiliary slide rod 4 by the operator.

[0028] like Figure 3As shown, both the slide bar 3 and the auxiliary slide bar 4 have through grooves 6 in the middle. The pressure bar 5 is set in the through groove 6 and fixed inside the through groove 6 by bolts at the top and bottom. When the operator loosens the bolts, the longitudinal and lateral positions can be adjusted inside the through groove 6.

[0029] The bottom of the pressure rod 5 is detachably equipped with a pressure head 7. The pressure head 7 is made of elastic material and its shape can be either a flat pressure head 7 or a toothed pressure head 7.

[0030] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
