Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically a protective hanger. Background Technology

[0002] Automotive parts painting hangers are key pieces of equipment specifically designed for suspending various automotive parts for painting operations. They are typically made of corrosion-resistant metal materials and possess certain high-temperature resistance and anti-paint adhesion properties. They can stably suspend parts in the paint booth, ensuring that all surfaces of the parts are fully exposed to the painting environment, facilitating uniform paint coverage. They are an important auxiliary tool for ensuring painting quality and improving painting efficiency, and have now become an indispensable piece of equipment in the mass production of automotive parts.

[0003] However, during the use of automotive parts painting hangers, due to the close proximity of some hanger suspension points, the contact area between the hanger and the parts is too large, causing the parts that are covered to be unable to be painted properly, affecting the integrity and consistency of the paint job. Furthermore, because the structure of the hangers is relatively fixed, it is difficult to adapt and adjust to automotive parts with complex shapes and diverse sizes. During the painting process, parts are prone to shaking and rotation, which can easily cause problems such as paint drips and uneven coating thickness. Utility Model Content

[0004] The purpose of this utility model is to provide a protective hanger to solve the problems mentioned in the background art, which are that due to the close proximity of some hangers, the contact area between the hanger and the parts is too large, resulting in the parts being covered and unable to be painted normally, affecting the integrity and consistency of the paint spraying. Furthermore, due to the relatively fixed structure of the hanger, it is difficult to adapt and adjust to automotive parts with complex shapes and diverse sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective hanger, including a main rod, which serves as the main support structure of the hanger. The main rod passes through a pre-set through hole of a support frame along the axial direction, and the support frames are spaced apart on the surface of the main rod. The main rod and the support frames together constitute the main frame structure of the protective hanger workpiece. The support frame has two through-shaped guide rails, and each guide rail has a support seat that slides in it. Each support seat has a suspension positioning spike at both ends. The support frame is fitted with a positioning rod at each end, and the positioning rod is arranged parallel to the main rod. The main rod, the support frame and the positioning rod form a grid-like frame structure. The top surface of the positioning rod has a thread, and the external thread at the top of the positioning rod is threaded to the locking member. The locking member abuts against the uppermost support frame.

[0006] Using the above technical solution, the frame structure formed by the main rod and the load-bearing frame provides stable support, the sliding cooperation between the guide rail and the support seat allows for flexible adjustment of the suspension position, and the suspension positioning spikes reduce the contact area to avoid paint obstruction.

[0007] Preferably, the main rod passes through the connecting sleeve, and the connecting sleeve is fitted onto the surface of the support frame.

[0008] By adopting the above technical solution, the connecting sleeve enhances the connection strength between the main rod and the bearing frame, reduces radial sway, improves the overall stability of the hanger, and ensures the safety of the workpiece during suspension.

[0009] Preferably, the bearing frame has annular structures at both ends, and the bearing frames are equidistantly distributed along the axial direction of the main rod, and there is a spacer between the two bearing frames.

[0010] By adopting the above technical solution, the ring structure at both ends of the support frame is easy to cooperate with the positioning rod, and the axially equidistant support frame combined with the spacer sleeve avoids the workpieces from colliding with each other, while optimizing space utilization.

[0011] Preferably, the support frame and the bottom of the main rod have cylindrical baffles, and the top of the main rod is fitted with a lifting ring.

[0012] By adopting the above technical solution, the bottom baffle restricts the axial displacement of the components to prevent them from falling off, and the top hanging ring facilitates the hanging and installation of the fixture, thereby improving the ease of installation and safety of use of the fixture.

[0013] Preferably, the spacer is fitted onto the surface of the positioning rod, and the side of the spacer closest to the guide rail is designed with a fan-shaped opening.

[0014] By adopting the above technical solution, the fan-shaped opening structure of the spacer avoids the guide rail and the workpiece, thus preventing the painting area from being blocked. It is fitted on the positioning rod to ensure that the support frame is evenly distributed, further ensuring the painting effect.

[0015] Preferably, the support base has holes at both ends that engage with the bottom end of the suspension positioning spike, and the suspension positioning spike and the support base form a U-shaped structure.

[0016] By adopting the above technical solution, the interlocking connection between the support seat and the suspension positioning spike forms a U-shaped structure, which enhances the clamping stability of the workpiece, prevents the workpiece from shaking, and is suitable for workpieces of various shapes.

[0017] Preferably, each of the support surfaces is fitted with two silicone sleeves, and the surfaces of the silicone sleeves abut against the support frame and the suspension positioning spikes, respectively.

[0018] By adopting the above technical solution, the silicone sleeve reduces the friction between the support seat and the carrier frame and the suspension positioning spikes, avoiding scratches on the workpiece surface. At the same time, it buffers the impact force through elastic deformation, improving the protective effect.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This protective hanger: 1. This protective hanger increases the number of car parts that can be hung by its structural design of suspension positioning spikes and support base. The suspension positioning spikes adopt a spike-like structure and are connected by the holes at both ends of the support base to form a U-shaped structure. The contact with the workpiece is only point contact, which greatly reduces the contact area between the hanger and the part. At the same time, the fan-shaped opening structure of the spacer near the guide rail can avoid the workpiece surface and prevent the spacer itself from obstructing the painting area, thus ensuring the integrity and consistency of the painting. 2. The sliding cooperation between the guide rail and the support seat allows the support seat to be flexibly adjusted along the guide rail. Combined with the snap-fit ​​installation of the suspension positioning spikes, it can quickly adapt to the suspension points according to the shape and size of the parts. The threaded connection structure between the positioning rod and the locking part allows the spacing of the support frame to be adjusted by loosening the locking part. Combined with the equidistant separation function of the spacer, it can further adapt to the suspension requirements of parts of different sizes, thereby realizing a multi-dimensional adjustment structure. This allows the hanger to flexibly cope with automotive parts with complex shapes and diverse sizes, effectively improving adaptability. 3. The grid structure formed by the main rod, the support frame, and the positioning rod provides a stable support framework. The connecting sleeve strengthens the connection between the main rod and the support frame, while the silicone sleeve reduces friction between components and prevents the hanger from scratching the surface of the parts. Through the combined effect of the structures, the hanger not only improves operational safety but also extends its service life while ensuring its load-bearing stability, providing stable auxiliary support for the painting process of automotive parts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a protective hanger, including a main rod 1, a bearing frame 2, a connecting sleeve 3, a hanging ring 4, a positioning rod 5, a spacer 6, a locking component 7, a guide rail 8, a support seat 9, a suspension positioning spike 10, and a silicone sleeve 11; Among them, the main rod 1 serves as the main support structure of the hanger. The main rod 1 passes through the pre-set through hole of the bearing frame 2 along the axial direction, and the bearing frame 2 is distributed at intervals on the surface of the main rod 1. The main rod 1 and the bearing frame 2 together constitute the main frame structure of the protective hanger workpiece. The support frame 2 has two through guide rails 8, and a support seat 9 slides in each guide rail 8. Each support seat 9 has a suspension positioning spike 10 at both ends. The support seat 9 has holes at both ends that engage with the bottom of the suspension positioning spike 10. The suspension positioning spike 10 and the support seat 9 form a U-shaped structure. Each support seat 9 has two silicone sleeves 11 on its surface, and the surface of the silicone sleeves 11 abuts against the support frame 2 and the suspension positioning spike 10 respectively. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the hanger is first assembled. First, the main rod 1 is placed horizontally. The pre-set through holes of the bearing frame 2 and the connecting sleeve 3 are aligned with the main rod 1 in sequence and penetrated the main rod 1 along the axial direction, so that the bearing frame 2 is distributed at intervals on the surface of the main rod 1. Since the connecting sleeve 3 is sleeved on the connection part of the main rod 1 and the bearing frame 2, it is ensured that the connecting sleeve 3 fits tightly with both, thereby enhancing the connection strength. Secondly, positioning rods 5 are inserted into the annular structures at both ends of the support frame 2, so that the positioning rods 5 are parallel to the main rod 1, such as... Figures 1-3 As shown, a spacer 6 is fitted onto the positioning rod 5 between two adjacent support frames 2. Note that the fan-shaped opening of the spacer 6 should face the guide rail 8. After completion, check whether the support frames 2 are evenly distributed along the axial direction. Finally, screw the locking piece 7 into the external thread at the top of the positioning rod 5, and initially tighten it until it slightly abuts against the uppermost support frame 2. Then, fit the lifting ring 4 into the preset mounting position at the top of the main rod 1, ensuring that the fit is firm. Check that the cylindrical baffles at the bottom of the main rod 1 and the support frame 2 restrict the axial displacement of each component. One positioning rod 5 is fitted at each end of the support frame 2, and the positioning rod 5 is set parallel to the main rod 1. The main rod 1, the support frame 2 and the positioning rod 5 form a grid-like frame structure. The top surface of the positioning rod 5 is threaded. The external thread at the top of the positioning rod 5 is threaded to the locking part 7. The locking part 7 abuts against the uppermost support frame 2. The main rod 1 passes through the connecting sleeve 3, and the connecting sleeve 3 is fitted on the surface of the support frame 2. The two ends of the support frame 2 are ring structures, and the support frames 2 are equidistantly distributed along the axial direction of the main rod 1. There is a spacer 6 between the two support frames 2. The bottom of the support frame 2 and the main rod 1 has a cylindrical baffle. The top of the main rod 1 is fitted with a lifting ring 4. The spacer 6 is fitted on the surface of the positioning rod 5, and the side of the spacer 6 near the guide rail 8 is set with a fan-shaped opening structure. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the assembled hanger is suspended on the hook of the external conveying device or bracket by the lifting ring 4 at the top of the main rod 1, ensuring that the lifting ring 4 is firmly connected to the external structure and the hanger is kept horizontal. Then, according to the size and shape of the car parts to be processed, the locking piece 7 at the top of the positioning rod 5 is loosened. When it is necessary to adjust the spacing of the carrier frame 2, the number of spacers 6 is increased or decreased or spacers 6 of different thicknesses are replaced. After the adjustment is completed, the locking piece 7 is tightened again to fix the position of the carrier frame 2. By pushing the support seat 9, it slides along the through guide rail 8 inside the support frame 2. During the process, observe the position of the suspension positioning spikes 10 at both ends until they can accurately correspond to the preset fixing point of the workpiece. After stopping the pushing, the support seat 9 is temporarily fixed due to the friction of the rail. Place the car part smoothly on the support seat 9 so that the suspension positioning spikes 10 can penetrate or clamp the fixing point of the workpiece. At this time, the suspension positioning spikes 10 of the U-shaped structure cooperate with the support seat 9 to form a stable support. At the same time, the silicone sleeve 11 on the surface of the support seat 9 contacts the workpiece to reduce friction and avoid scratching the surface of the workpiece. After confirming that the suspension positioning spike 10 is firmly locked to the car part, the external conveying device is activated, and the hanger carries the workpiece into the painting and other processing stages, or it is painted by the operator. After the processing is completed, the workpiece is cooled or dried, and the workpiece is removed by reversing the operation. The remaining paint or impurities on the surface of the hanger are cleaned for the next use.

[0024] Working principle: When using this protective hanger, during operation, the main rod 1 is axially inserted through the preset through hole of the support frame 2, so that the support frame 2 is distributed at intervals along the surface of the main rod 1. Then, the positioning rods 5 are fitted into both ends of the support frame 2, so that the positioning rods 5 are parallel to the main rod 1, forming a grid-like frame structure. By fitting spacers 6 on the positioning rods 5 between adjacent support frames 2, the support frames 2 are ensured to be equidistantly distributed along the axial direction. Finally, the hanger is suspended on an external conveying device or bracket through the lifting ring 4 at the top of the main rod 1. The cylindrical baffle at the bottom end will restrict the axial displacement of the support frame 2 and the positioning rods 5. Then, adjust the position of the support seat 9 according to the size of the workpiece. By pushing the support seat 9, it slides along the through guide rail 8 inside the support frame 2 until the suspension positioning spikes 10 at both ends can accurately correspond to the fixing point of the workpiece. At this time, the suspension positioning spikes 10 of the U-shaped structure cooperate with the support seat 9, and lift the workpiece over the support point according to the position of the workpiece. Place the workpiece on the support seat 9, so that the suspension positioning spikes 10 can penetrate or clamp the workpiece. The silicone sleeve 11 on the surface of the support seat 9 supports the part of the workpiece close to the support seat 9, reduces friction and avoids scratching the workpiece, and increases the overall practicality.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
