Description

Technical Field

[0001] This utility model relates to the field of cable reels, and in particular to a cable reel welding positioning fixture. Background Technology

[0002] Existing cable reels are usually assembled by welding two side reels and a central shaft. The concentricity of the side reels and the central shaft directly affects the balance and operational stability of the cable reel during the winding and unwinding process.

[0003] In actual production, the side plate and the central shaft are often welded after being manually positioned. Due to the lack of precise concentric positioning and the fact that the central shaft is prone to offset during the welding process, the central shaft and the side plate are not on the same axis. This eccentricity not only causes uneven stress on the weld and affects the welding quality, but also causes the cable reel to rotate unbalanced, and in severe cases, it can even cause structural deformation.

[0004] Therefore, how to provide a simple and reliable welding positioning fixture that enables the cable reel side plate and the central shaft to be quickly and accurately concentrically positioned before welding has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The technical solution provided by this utility model is as follows: a cable reel welding positioning fixture, comprising: a base plate, positioning posts set on the base plate, and multiple clamping structures arranged on the base plate and along the circumference of the positioning posts; wherein, the positioning posts and clamping structures are coaxially arranged. The clamp structure includes: a base connected to the base plate, and a clamping claw hinged to the base.

[0007] In one embodiment, the thickness of the base is greater than the thickness of the cable reel side plate.

[0008] In one embodiment, the inner wall of each base is tangent to the outer side of the cable reel.

[0009] In one embodiment, the outer diameter of the positioning post is smaller than the inner diameter of the cable reel's central shaft.

[0010] In one embodiment, a pin hole is provided on the base, a pin shaft is axially connected inside the pin hole, a connecting plate is connected to the pin shaft, and a gripper is connected to the end of the connecting plate; the gripper adjusts the opening and closing angle through the pin shaft to achieve clamping of the outside of the central shaft of the cable reel.

[0011] In one embodiment, the gripper is fan-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The cable reel welding positioning fixture of this utility model adopts a positioning post and multiple clamping structures arranged coaxially around it for coordinated positioning. The inner hole of the cable reel side plate is sleeved on the positioning post to achieve the positioning of the side plate. The flip-out clamping claw clamps the cable reel center axis from the outside, thereby achieving the purpose of quickly and accurately positioning the cable reel side plate and the center axis of the cable reel concentrically before welding. This achieves the technical effect of accurate welding positioning and high concentricity, and solves the problems of existing cable reel side plate and cable reel center axis being difficult to keep coaxial, welding eccentricity causing product imbalance and low processing accuracy.

[0015] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0016] like Figure 1-4 As shown, this utility model is a cable reel welding positioning fixture, including a base plate 1, a positioning post 2, and multiple clamping structures 3 arranged around the circumference of the positioning post 2; the positioning post 2 is fixedly set at the center of the base plate 1 and is used to insert into the inner hole 6 of the cable reel side plate 4, so that the cable reel side plate 4 can be stably placed on the base plate 1 and kept coaxial with the positioning post 2, thereby limiting the position of the cable reel side plate 4.

[0017] The clamping structure 3 is evenly distributed around the circumference of the positioning column 2, including: a base 31 fixed on the base plate 1 and a gripper 32 connected to the base 31 and capable of flipping; wherein, when the gripper 32 flips to the inside to clamp the central axis 5 of the cable reel, the inner side of the gripper 32 is coaxial with the positioning column 2.

[0018] Specifically, after the cable reel side plate 4 is inserted into the positioning post 2 through the inner hole 6, the cable reel central shaft 5 is placed on the cable reel side plate 4, and then each gripper 32 is flipped so that its inner side is tightly attached to the outer circle of the cable reel central shaft 5, thereby making the cable reel central shaft 5 and the cable reel side plate 4 coaxially arranged. Through this structure, the cable reel central shaft 5 and the cable reel side plate 4 can be accurately positioned on the same axis, and the cable reel central shaft 5 is limited to avoid offset errors during the welding process.

[0019] The welding positioning fixture of this utility model adopts a collaborative positioning method using a positioning post 2 and multiple clamping structures 3 arranged coaxially around it. The inner hole 6 of the cable reel side plate 4 is fitted onto the positioning post 2 to achieve the positioning of the side plate. The flip-out clamping claw 32 clamps and limits the cable reel central axis 5 from the outside, thereby achieving the purpose of quickly and accurately positioning the cable reel side plate 4 and the central axis 5 of the cable reel concentrically before welding. This achieves the technical effect of accurate welding positioning and high concentricity, and solves the problems of existing cable reel side plates and cable reel central axis being difficult to keep coaxial, welding eccentricity causing product imbalance and low processing accuracy.

[0020] The inner wall of each base 31 is tangent to the outer edge of the cable reel side plate 4, thereby further defining the position of the cable reel side plate 4 and improving assembly stability.

[0021] The outer diameter of the positioning post 2 is designed to be slightly smaller than the diameter of the inner hole 6 of the cable reel side plate 4, so that the cable reel side plate 4 can be inserted smoothly.

[0022] Specifically, a pin hole 33 is provided on the base 31, and a pin shaft 34 is rotatably connected in the pin hole 33. A connecting plate 35 is connected to the pin shaft 34, and a gripper 32 is fixedly connected to the end of the connecting plate 35. The gripper 32 is flipped through the pin shaft 34, thereby clamping and limiting the outer surface of the cable reel center shaft 5. Through the clamping action of the gripper 32, the cable reel center shaft 5 is coaxially positioned with the cable reel side plate 4, and the cable reel center shaft 5 is kept fixed during the welding process to avoid eccentricity.

[0023] In this embodiment, the inner side of the gripper 32 is arc-shaped and fits the outside of the cable reel central axis 5; and the inner side of each gripper 32 forms a circle, and this circle is concentric with the positioning post 2; thus, the concentric limit and full-circumference clamping positioning of the cable reel central axis 5 are realized; when clamping the cable reel central axis 5, this structure can apply force from multiple directions simultaneously, so that the cable reel central axis 5 and the cable reel side plate 4 remain coaxial, significantly improving the coaxiality and positioning accuracy during welding, avoiding eccentricity or shaking, and ensuring welding quality and product consistency.

[0024] Working principle: In use, firstly, the cable reel side plate 4 is fitted onto the positioning post 2 through the inner hole 6, making it stably placed on the base plate 1; then, the cable reel central shaft 5 is placed on the cable reel side plate 4; next, the gripper 32 is flipped so that its arc-shaped inner wall fits against the outer surface of the cable reel central shaft 5, thereby limiting the coaxial positioning of the cable reel central shaft 5 and the cable reel side plate 4; finally, welding is performed while maintaining coaxiality. During welding, the gripper 32 can be flipped to ensure a full circle of welding. Through the clamping and positioning of this embodiment, the cable reel central shaft 5 and the cable reel side plate 4 can accurately maintain coaxiality during welding, avoiding eccentricity during welding and improving the product assembly accuracy.
