Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture processing technology, specifically to a three-piece bracket welding fixture. Background Technology

[0002] In machining, especially in product assembly and welding, precisely and efficiently welding three-piece frames to the product casing is a crucial and common process. However, the currently prevalent methods have significant technical shortcomings, severely restricting production efficiency and product quality.

[0003] In the existing process of welding three-piece tripods to the housing, the operator mainly relies on visual inspection of markings on the tripods or housing for manual alignment. This purely manual visual positioning method has significant drawbacks: First, the positioning accuracy is poor and the error is large. Human judgment is subject to visual errors, and manual operation is prone to tremors, causing the welding position of the three-piece tripods to frequently shift ("welding misalignment"), affecting the product's appearance and function. Second, production efficiency is low. The visual alignment process is tedious and time-consuming, requiring repeated fine-tuning, which seriously slows down the production cycle. Third, operators are prone to fatigue. Prolonged periods of high concentration for detailed visual work can easily cause visual fatigue, increasing the risk of operational errors. Most seriously, it leads to a high product scrap rate. When welding misalignment exceeds the tolerance range, it often causes irreversible damage to the workpiece or component, resulting in scrap, wasting materials, time, and energy, and driving up costs. Therefore, existing technologies lack a dedicated welding fixture that can quickly and stably position and clamp a three-piece tripod to systematically solve the problems of poor accuracy, low efficiency, high labor intensity, and high scrap rate caused by manual positioning, and urgently needs improvement.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: A three-piece scaffold welding fixture includes a base plate assembly and a support plate assembly. The support plate assembly is located above the base plate assembly. The base plate assembly has a fixed insulating plate at the front end of the support plate assembly. The insulating plate has a hole in its middle. The support plate assembly has a lower electrode at the corresponding position of the hole. The front end of the insulating plate has three positioning posts evenly distributed around the perimeter of the hole. An upper electrode that can move up and down is located above the front end of the insulating plate. In use, the outer shell product is placed in the hole. A copper tube is installed on the outer shell product, and the copper tube abuts against one of the positioning posts.

[0006] Furthermore, the support plate assembly is fixedly connected to the base plate assembly.

[0007] Furthermore, the base plate assembly includes an upper base plate and a lower base plate, wherein the size of the upper base plate is larger than the size of the lower base plate.

[0008] Furthermore, the top of the upper electrode is fixed to the fixed base, and the up-and-down movement of the upper electrode is driven by a cylinder.

[0009] Furthermore, during use, one end of the outer casing is in contact with the lower electrode, and the upper electrode and the three-piece stand are pressed down together and welded to the outer casing.

[0010] Furthermore, the holes are matched to the outer casing product.

[0011] The beneficial effects of this utility model are as follows: By setting three evenly distributed positioning posts around the holes in the insulating plate, the outer shell product is placed inside the holes in the insulating plate during use.
