[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 4As shown, the utility model provides a circular connector welding and fixing device, comprising a support plate 1, a vertical plate 2 and a fixed clamp 31 provided on the support plate 1, a push-pull quick clamp 4 vertically provided at the upper end of the vertical plate 2 and located above the fixed clamp 31, and a movable clamp 32 connected to the lower end of the push-pull quick clamp 4. The push-pull quick clamp 4 is used to drive the movable clamp 32 to move in the vertical direction to cooperate with the fixed clamp 31 to clamp or release the circular connector. The push-pull quick clamp 4 includes a clamp seat 41 extending in the vertical direction, a handle 42 hinged to the upper end of the clamp seat 41 and rotating up and down, a limiting cylinder 43 provided at the lower end of the clamp seat 41 and extending in the vertical direction, a push-pull rod 44 provided in the limiting cylinder 43 and movable along the axis of the limiting cylinder 43, and a connecting rod 45 having its ends hinged to the upper end of the push-pull rod 44 and the handle 42, respectively.

[0036] In the present invention, when in operation, the handle 42 is first rotated upward, which in turn drives the connecting rod 45, the push-pull rod 44, and the movable splint 32 upward. The circular connector is then placed on the fixed splint 31. The handle 42 is then rotated downward, which in turn drives the connecting rod 45, the push-pull rod 44, and the movable splint 32 downward, so that the movable splint 32 and the fixed splint 31 clamp the circular connector. Finally, the circular connector is welded. The push-pull quick clamp 4 of the present invention adopts the working principle of a crank slider mechanism, wherein the clamp base 41, handle 42, connecting rod 45, and push-pull rod 44 respectively correspond to the frame, crank, connecting rod, and slider in the crank slider mechanism. In the present invention, the push-pull quick clamp 4 can realize the rapid lifting and lowering of the movable splint 32, and then cooperate with the fixed splint 31 to realize the clamping and loosening of the circular connector. Compared with the existing technology of clamping and loosening the movable splint 32 and the fixed splint 31 by bolt connection, it not only has high production efficiency and can realize mass production, but also does not require the use of tools such as wrenches during operation, is simple to operate, and has low labor intensity.

[0037] like Figures 1 to 3 As shown, the handle 42 includes a driving section 421 and a hand-held section 422 connected to the driving section 421 at an obtuse angle. The upper end of the connecting rod 45 is hinged at the connection between the driving section 421 and the hand-held section 422. The clamp base 41 is also provided with a vertical stop plate 46 for the lower end of the driving section 421 to abut. When the driving section 421 abuts the stop plate 46, the driving section 421, the connecting rod 45, and the push-pull rod 44 are collinear. The lower end of the push-pull rod 44 is provided with a mounting plate 6, which is connected to the movable splint 32 via a floating connection structure 7. When the driving section 421 abuts the stop plate 46, the handle 42 rotates to its lowest position.

[0038] In the present invention, the clamp base 41, handle 42, connecting rod 45, stopper 43, and push-pull rod 44 of the push-pull quick clamp 4 are all made of steel or aluminum alloy. The grip section 422 is designed for handholding and is covered with a rubber sheath to prevent sharp edges from the metal grip section 422. Furthermore, the obtuse angle between the grip section 422 and the drive section 421 facilitates manual exertion. When handle 42 is rotated downward, it drives connecting rod 45, push-pull rod 44, mounting plate 6, floating connection structure 7, and movable clamp 32 to move downward synchronously. When movable clamp 32 contacts the circular connector or fixed clamp 31, the floating connection structure 7 allows handle 42 to continue to rotate downward, driving connecting rod 45, push-pull rod 44, and mounting plate 6 downward until the driving section 421 of handle 42 abuts stop plate 46. At this point, the driving section 421, connecting rod 45, and push-pull rod 44 are collinear, at a "dead point" position, and in a state of force equilibrium, locking push-pull rod 44. At this point, releasing handle 42 will not loosen mounting plate 6 and movable clamp 32, allowing welding of the circular connector to proceed. Furthermore, the floating connection structure 7 ensures flexible contact between movable clamp 32 and the circular connector, preventing damage to the circular connector during the clamping process. When welding is completed, the handle 42 rotates upward, driving the drive section 421 to rotate, so that the drive section 421 is no longer vertically set, breaking the force balance state, releasing the lock on the push-pull rod 44, and then driving the connecting rod 45, push-pull rod 44, mounting plate 6, floating connection structure 7 and movable splint 32 to move upward.

[0039] A first rotation axis is located at the junction of the handle section 422 and the drive section 421. Two connecting rods 45 are provided, located on either side of the drive section 421. The upper ends of the two connecting rods 45 are hinged to the ends of the first rotation axis. A second rotation axis is located at the upper end of the push-pull rod 44. The lower ends of the two connecting rods 45 are hinged to the ends of the second rotation axis. The provision of two connecting rods 45 ensures more reliable transmission and smoother movement.

[0040] like Figure 1 、 Figure 2 and Figure 4 As shown, the floating connection structure 7 includes a guide cylinder 71 vertically fixed to the mounting plate 6, with both upper and lower ends extending out of the mounting plate 6; and a guide column 72 vertically sleeved within the guide cylinder 71, with its lower end fixed to the movable clamping plate 32. An annular baffle 73 is provided at the upper end of the guide cylinder 71, through which the guide column 72 passes. The guide column 72 includes a stopper 721, a mounting section 722, and a connecting section 723, arranged sequentially from top to bottom. The diameter of the mounting section 722 is smaller than that of the connecting section 723. A spring 74 is sleeved between the mounting section 722 and the guide cylinder 71, resting against the upper end surfaces of the annular baffle 73 and the connecting section 723, respectively.

[0041] In the present invention, the push-pull rod 44 drives the mounting plate 6 downward, which in turn drives the movable plate 32 downward synchronously via the guide cylinder 71, spring 74, and guide post 72. When the movable plate 32 contacts the fixed plate 31 or the circular connector, the fixed plate 31 or the circular connector prevents the movable plate 32 and its connected guide post 72 from moving. The mounting plate 6 then continues to move downward, driving the guide cylinder 71 and the annular baffle 73 downward and compressing the spring 74, reducing the distance between the mounting plate 6 and the movable plate 32. This occurs until the driving section 421 abuts the stop plate 46, at which point the spring 74 reaches its maximum compression and exerts maximum pressure on the movable plate 32, clamping the circular connector. When the push-pull rod 44 drives the mounting plate 6 upward, the spring 74 returns to its original position, increasing the distance between the mounting plate 6 and the movable plate 32. The spring 74 propels the mounting plate 6 and the movable plate 32 apart, while the stop 721 acts as a limiter for the guide cylinder 71. The floating connection structure 7 in this embodiment has a compact structure, a small volume, and a low cost, and can meet the use requirements.

[0042] In some alternative embodiments, the floating connection structure 7 includes a vertically arranged polished rod with its lower end fixed to the top of the movable clamping plate 32. The upper end of the polished rod extends through the mounting plate 6, and the upper end of the polished rod is provided with a stopper for abutting against the mounting plate 6. A spring is sleeved on the polished rod to abut between the movable clamping plate 32 and the mounting plate 6.

[0043] like Figure 1 and Figure 2 As shown, the adjacent sides of the movable clamping plate 32 and the fixed clamping plate 31 are each provided with a concave arc-shaped clamping surface. A flexible protective cover 5 is provided on the arc-shaped clamping surface. The flexible protective cover 5 can be made of a flexible material such as rubber or silicone. Both the movable clamping plate 32 and the fixed clamping plate 31 are made of epoxy board, which has high mechanical and dielectric properties, good heat and moisture resistance, and good machinability, meeting the requirements of use.

[0044] In this utility model, the concave arc-shaped clamping surface matches the outer circumference of the cylindrical circular connector, resulting in a larger contact area and a tighter fit during clamping. This prevents the circular connector from rotating or shifting during welding, thereby ensuring weld quality. Furthermore, the flexible protective sleeve 5 prevents damage to the circular connector caused by excessive clamping force.

[0045] In some other embodiments, the two adjacent side surfaces of the movable clamping plate 32 and the fixed clamping plate 31 are respectively provided with clamping surfaces of other shapes, so as to clamp circular connectors or other workpieces of other specifications and shapes.

[0046] like Figure 1 and Figure 2As shown, the circular connector welding fixture also includes a base 8 and two side panels 9 vertically arranged on both sides of the base 8. The base 8 is made of cast iron. Cast iron has the advantages of high strength, good wear resistance, and good pressure resistance, which can meet the requirements of use. The side panels 9 are made of epoxy board. Each side panel 9 is provided with two oppositely arranged arc-shaped waist holes 91 and a first rotating hole 92 arranged between the two arc-shaped waist holes 91. The corresponding side surface of the support plate 1 is provided with two second rotating holes 11 matching the arc-shaped waist holes 91 and a third rotating hole 12 located between the two second rotating holes 11 and matching the first rotating hole 92.

[0047] In the present invention, during use, the support plate 1 is first pre-secured to the side plate 9 via the third pivot hole 12 and the first pivot hole 92. It is then connected to various locations on the curved waist hole 91 via the second pivot hole 11. The third pivot hole 12 and the first pivot hole 92 are then tightened, positioning the support plate 1 at a specific angle relative to the horizontal plane. By adjusting the position of the second pivot hole 11 on the curved waist hole 91, the angle of the support plate 1 can be adjusted, thereby adjusting the angles of the movable clamping plate 32, the fixed clamping plate 31, and the circular connector held therein. This allows for adjustments to accommodate operators of varying heights, sitting postures, and welding angles.

[0048] Angle scale values ​​are provided on the side plate 9 along the extending direction of the arc-shaped waist hole 91. By setting the angle scale values, the operator can adjust to the required tilt angle conveniently, thereby facilitating the purpose of rapid adjustment.

[0049] like Figure 1 and Figure 2 As shown, a long hole or a plurality of adjustment holes 21 are provided on the vertical plate 2. The push-pull quick clamp 4 is adjusted vertically on the vertical plate 2 through the long hole or the adjustment hole 21. The material of the vertical plate 2 can be epoxy board.

[0050] In the present invention, by adjusting the height of the push-pull quick clamp 4 up and down, the height of the lower end of the push-pull rod 44 can be adjusted, and then the distance between the movable clamp 32 and the fixed clamp 31 can be adjusted. It can be applied to circular connectors of different height specifications, so that the clamping effect of the circular connector is better.

[0051] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "upper", "lower", "horizontal", "top", "bottom", "inside", "outside" and other terms indicating orientation or positional relationships are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.

[0052] In addition, in the description of this specification, “a plurality of” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
