Technical Field

[0001] This utility model belongs to the field of high-pressure common rail pipe processing equipment, and in particular relates to a support for surface treatment of high-pressure common rail pipe. Background Technology

[0002] The common rail in an automotive system stores high-pressure fuel supplied by the high-pressure fuel pump and distributes it evenly to each electronic fuel injector. It also acts as an accumulator, stabilizing fuel pressure and ensuring precise fuel injection. As a precision component of the engine's high-pressure common rail system, the high-pressure common rail requires rigorous surface treatments to prevent corrosion in natural environments, including electroplating, oxidation, and phosphating.

[0003] Currently, due to environmental protection requirements, most manufacturers lack the capability for surface treatment, and all surface treatments must be outsourced. During outsourcing and transportation, products must be protected from impacts, and the appearance of all surface treatments must be uniform. Typical surface treatments involve multiple processes, requiring the product to be moved up and down between different tanks, making it highly susceptible to damage. Therefore, a support structure needs to be designed that meets the requirements of both transportation and surface treatment operations to ensure product quality. Utility Model Content

The top and bottom of the base are open. The columns are arranged in pairs on both sides of the base. Each column includes two symmetrically distributed angle steels with their corners facing away from each other. The two ends of the hooks are fixedly connected to the gaps between adjacent angle steels. Multiple support shafts are evenly distributed along their height direction between the angle steels. Multiple pairs of hanging branches are evenly distributed along their axial direction on the support shafts. The hanging branches are inclined and used to interlock with the high-pressure common rail pipe. A baffle is provided in the extending direction of the hanging branches.

[0006] Preferably, the base includes four bottom angle steels connected end to end in a U-shape, with the corners of the bottom angle steels facing upwards, and a base plate is provided between the opposite bottom angle steels.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figures 1-4 As shown, the present invention provides a support for surface treatment of high-pressure common rail pipe, including a base 1, on which columns 2 and hooks 3 are provided. The top and bottom of the base 1 are open. The columns 2 are arranged in pairs on both sides of the base 1. Each column 2 includes two symmetrically distributed angle steels 21 with their corners facing away from each other. The two ends of the hooks 3 are fixedly connected to the gaps between the adjacent angle steels 21. Multiple support shafts 4 are evenly distributed along their height direction between the angle steels 21. Multiple pairs of hanging branches 5 are evenly distributed along their axial direction on the support shafts 4. The hanging branches 5 are inclined and used to interlock with the high-pressure common rail pipe 7. A baffle 6 is provided in the extension direction of the hanging branches 5.

[0021] Specifically, the main body, consisting of a base 1, a column 2, and a hook 3, can be suspended. The hook 3 can be used for hand-held or robotic arm transfer, and can also be used to suspend the pipe during surface treatment. The column 2 uses a pair of angle steels with high structural strength to provide welding joints for the support shaft 4 and the hook 3, and the support shaft 4 provides welding joints for the hanging branch 5. The hanging branch 5 serves as the placement end for the high-pressure common rail pipe 7. This device can simultaneously hold multiple high-pressure common rail pipes 7, with adjacent high-pressure common rail pipes 7 remaining independent and not in contact, preventing significant collisions. Furthermore, a baffle 6 prevents the high-pressure common rail pipes 7 from slipping out of the hanging branch 5 and falling during transfer, facilitating transfer and transportation and ensuring product quality. Moreover, the device has an overall hollow design, which allows for the placement of a large number of high-pressure common rail pipes 7 at once, while ensuring that the high-pressure common rail pipes 7 do not interfere with each other. This facilitates simultaneous surface treatment of all high-pressure common rail pipes 7 on this device, and the working medium in the surface treatment process can fall along the hollow parts of the device, preventing large-area residue on the product. The hanging branch 5 is made of stainless steel and can withstand the corrosion of repeated surface treatments.

[0022] To improve the practicality of the base 1, the base 1 provided by this utility model includes four bottom angle steels 11 connected end to end in a U-shape, with the corners of the bottom angle steels 11 facing upwards. A base plate 12 is provided between the opposing bottom angle steels 11, and there are two base plates 12 welded together to form a cross structure. The bottom angle steels 11 constitute a base 1 with an open structure at both the top and bottom. Their corners provide corresponding welding nodes for the upright angle steels 21 and the guard rods 8. Furthermore, the base plate 12 and the bottom angle steels 11 together ensure the structural strength of the base 1, resulting in strong resistance to deformation and a long service life.

[0023] To improve the protection performance of this device for all high-pressure common rail pipes 7, in addition to the baffle 6, this utility model provides a guard rod 8 at the connection position of adjacent bottom angle steel 11. The guard rod 8 includes a vertical section 81 and an inclined section 82, with the inclined section 82 connected to the corner joint of the vertical angle steel 21. This provides a certain degree of protection for all high-pressure common rail pipes 7 on the side of the device, and also allows the column 2, base 1, and guard rod 8 to form a triangular support system, which helps to ensure the strength and reliability of the overall structure of the device.

[0024] To facilitate the handling of the high-pressure common rail pipe 7, this invention designs the baffle 6 as a movable type. For example, a slot 9 is provided on the inner side of the vertical section 81. The slot 9 is used to movably insert the baffle 6. After the baffle 6 is inserted into the slot 9, its bottom rests against the corner face of the bottom angle steel 11, and the inner wall of the corner face prevents the baffle 6 from flipping over. Before handling the high-pressure common rail pipe 7, the baffle 6 can be removed from the slot 9, providing open space for handling the workpiece and improving the efficiency of handling the high-pressure common rail pipe 7.

[0025] To improve the practicality of the hook 3, the hook 3 provided by this utility model is a bent rod structure and is inverted triangular in shape. In this way, the hook 3 can be used as a handle for people to lift, and can also be used as a suspension node to be suspended in the surface treatment process. Moreover, the hook 3 is made of a long rod with a certain diameter by bending, which also has a certain resistance to deformation, and can form a good clamping and welding relationship with the vertical angle steel 21.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
