Abstract
Description
Technical Field
[0001] This utility model belongs to the field of paint spraying fixture technology, and more specifically, it relates to an adjustable paint spraying fixture assembly for automotive parts. Background Technology
[0002] When painting certain car parts, hangers are often used for suspension painting, which requires the use of corresponding hanger components.
[0003] Current paint spraying fixtures still have the following shortcomings:
[0004] 1. Most traditional hanging fixtures have fixed structures and lack adjustability. When faced with parts of different sizes and production quantities, they are difficult to adapt flexibly, resulting in limited usage scenarios. For example, for large parts, existing hanging fixtures may not provide sufficient hanging space and support strength; while for small parts, the fixtures may be too large, resulting in wasted space and reduced utilization of the production site.
[0005] 2. The assembly and disassembly process of traditional hangers is often quite complicated. Once a part is worn or damaged, maintenance personnel need to spend a lot of time and effort to disassemble and replace the entire unit. This not only increases maintenance costs, but also affects production progress due to long-term equipment downtime, resulting in significant economic losses for the company. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model provides an adjustable paint hanger assembly for automotive parts, thereby solving the problem mentioned in the background art that most traditional hangers have fixed structures and lack adjustability, making it difficult to adapt flexibly to parts of different sizes and production quantities, thus limiting their application scenarios.
[0007] The purpose and function of this utility model, an adjustable paint spraying attachment for automotive parts, are achieved through the following specific technical means:
[0008] An adjustable paint hanger assembly for automotive parts includes: a main rod; the main rod adopts a J-shaped rod structure; a fixing rod is fixedly installed at the bottom of the main rod by threaded engagement, and the fixing rod adopts a cross-shaped rod structure, with a screw hole structure at the top of the fixing rod; a first screw is fixedly installed at the bottom of the fixing rod; a cylindrical connecting rod is slidably arranged on the outside of the fixing rod, and a through-type cross-shaped groove structure is opened at the top of the connecting rod, and through-type annular groove structures are arranged at equal intervals on the outside of the connecting rod.
[0009] Furthermore, a bolt is provided on the outer bottom of the first screw via a threaded connection.
[0010] Furthermore, a fixing ring is fixedly installed at equal intervals on the outer side of the connecting rod. The fixing ring adopts a semi-circular ring structure, and a circular ring protrusion structure is provided on the inner side of the fixing ring. A through-hole structure is opened on both sides of the fixing ring. Two sets of circular groove structures are opened on the outer side of the fixing ring. A through-hole structure is opened at the top of the two sets of circular groove structures on the outer side of the fixing ring. A second screw is rotatably installed on both sides of the fixing ring through threaded engagement. A third screw is rotatably installed in the screw hole at the top of the fixing ring through threaded engagement.
[0011] Furthermore, a cylindrical outer rod is fixedly connected to the circular groove on the outer side of the fixing ring, and a through-hole structure is opened at the top of the inner end of the outer rod. The diameter of the screw hole at the top of the outer rod matches the diameter of the third screw. A screw hole structure is opened at the outer end of the outer rod. U-shaped hooks are fixedly arranged at equal intervals on both sides of the outer rod. A cylindrical extension rod is installed at the outer end of the outer rod through threaded engagement, and a screw hole structure is opened at the outer end of the extension rod. A fourth screw is fixedly installed at the inner end of the extension rod.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The hanging assembly of this utility model has strong adjustability. By sliding the connecting rod over the outside of the fixed rod, the overall height can be adjusted according to the size of the parts. Simultaneously, one or more sets of fixed rods can be combined and spliced according to production quantity. The screw hole at the top of the lower set of fixed rods is threadedly connected to the first screw at the bottom of the upper set of fixed rods, allowing for flexible increases or decreases in the number of hanging layers to adapt to different production scales and space requirements. One or more sets of extension rods can be threaded onto the outside of the outer rod. By rotating the extension rods, the overall length of the outer rod and extension rods can be adjusted, thereby meeting the suspension requirements of parts of different sizes and greatly improving the versatility and applicability of the hanging assembly.
[0014] The structural design of the hanger assembly offers significant advantages in disassembly and maintenance. During use, if a part (such as the retaining ring, outer rod, or extension rod) shows severe wear, it can be disassembled and replaced individually by following the reverse installation steps, without needing to replace the entire hanger. This design not only saves maintenance time but also reduces product maintenance costs, minimizes production downtime due to equipment repairs, and ultimately improves enterprise production efficiency.
