Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and more specifically, it relates to an H-shaped automotive covering adsorption tooling. Background Technology

[0002] With the continuous development of automotive manufacturing technology, consumers are increasingly demanding higher surface quality and structural functionality from automotive interior parts. In the production process of automotive interior parts, vacuum adsorption molding is a crucial step in ensuring a tight fit between the skin material and the frame, directly affecting the product's aesthetics, durability, and safety performance. Traditional encapsulation processes typically use flat or simply curved adsorption molds, employing vacuum negative pressure to uniformly adhere the skin material to the frame substrate under thermal activation. This method has become a relatively mature technological system.

[0003] However, with the innovation of automotive interior design, the application of wrapping components with complex spatial structures has increased significantly. These products generally feature multi-directional curved surfaces and partially inverted structures. In existing processes, when the wrapping component's skeleton has an inverted structure, conventional adsorption jigs struggle to form an effective sealed cavity. This results in insufficient negative pressure in localized areas during vacuum adsorption, preventing the surface material from fully extending to the inverted areas and easily leading to defects such as poor adhesion and wrinkles. This not only reduces product yield but also forces some manufacturers to adopt remedial measures such as segmented wrapping and manual correction, significantly increasing production costs and labor consumption. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an H-type automotive coating adsorption tooling that can effectively solve the problem of vacuum adsorption of complex coating parts while ensuring molding accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An H-shaped automotive body panel adsorption fixture includes a worktable. The upper space of the worktable is provided with an adsorption fixture body adapted to the shape of the H-shaped body panel. The adsorption fixture body is rigidly fixed to the worktable surface through a base connected to its bottom.

[0007] The outer periphery of the adsorption fixture body is an assembly structure that forms an interference fit with the inner cavity of the H-shaped automotive body panel.

[0008] The adsorption fixture body has symmetrically arranged axially sliding sliders on both sides along its length. The movement trajectory of the sliders is parallel to the central axis of the adsorption fixture body. At the two axial ends of the adsorption fixture body, there are two hinged baffles, one that can be rotated and the other that can be flipped.

[0009] The hinge axes of baffle one and baffle two are set perpendicular to the plane of the worktable.

[0010] The top plane of the slider and the corresponding surface of the adsorption fixture body form a continuous working surface.

[0011] The top of the adsorption fixture body is symmetrically equipped with mounting plates perpendicular to the worktable plane.

[0012] The lower edge of the mounting plate and the upper surface of the slider form a contact-type limiting structure. A detachable baffle three is provided between the two mounting plates. The working surface of the baffle three forms a mating contact with the top contour of the adsorption fixture body.

[0013] The present invention is further configured such that the extension length of the slider exceeds the axial end face of the adsorption fixture body, and the lateral edges of baffle one and baffle two form a surface contact constraint with the end of the slider.

[0014] The present invention is further configured such that: a handle is provided on the upper surface of the baffle three, and the handle is rigidly connected to the baffle three by at least two sets of fasteners.

[0015] The present invention is further configured such that the inner working surfaces of the first baffle and the second baffle are provided with guide grooves that cooperate with the movement trajectory of the slider.

[0016] The present invention is further configured such that: a snap-fit ​​groove is provided on the inner side of the slider, and the snap-fit ​​groove abuts against the side of the adsorption fixture body.

[0017] The present invention is further configured such that the base and the worktable are connected in a detachable manner by an array of threaded fastening components.

[0018] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0019] The initial positioning accuracy is ensured by the interference fit between the main body of the adsorption fixture and the H-shaped automotive wrapping part. The axial sliding of the sliders on both sides, combined with the flip-locking function of baffle one and baffle two, effectively covers the undercut area of ​​the wrapping part skeleton and forms a sealed cavity, significantly improving the uniformity of vacuum adsorption. The contact limit design between the top of the slider and the mounting plate prevents the component from shifting during operation. The abutment structure between baffle three and the main body of the adsorption fixture further strengthens the overall rigidity. The handle makes the disassembly and assembly of baffle three convenient and efficient. At the same time, the screw connection between the base and the worktable facilitates quick replacement and maintenance of the fixture. Finally, it realizes one-time molding of complex structure wrapping parts. It is suitable for products with relatively complex structures and undercut phenomena when placed in the fixture. The movable push block realizes the product is placed into the activation fixture for activation adsorption. Attached Figure Description

[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] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Working principle: When in use, first fold the baffle 5 and baffle 6 on both sides of the adsorption fixture body 2, and remove the baffle 8. Then move the slider 4 towards the adsorption fixture body 2.

[0025] Next, the H-shaped car body covering is fitted onto the outer wall of the adsorption fixture body 2. Then, the baffle 3 8 is put back. Under the pushing force of the baffle 3 8, the slider 4 expands outward until the slider 4 abuts against the H-shaped car body covering, fixing the H-shaped car body covering. At this time, the baffle 1 5 and the baffle 2 6 are flipped so that their inner grooves form a surface contact lock with the end of the slider 4, creating a sealing boundary covering the inverted structure of the covering. The mounting plate 7 is pressed against the top of the slider 4 to restrict vertical displacement. The baffle 3 8 is inserted between the two mounting plates 7 and abuts against the top of the fixture body to form a top seal. The cross-section of the baffle 3 8 is "T" shaped, which can effectively limit the slider 4.

[0026] At this time, the inner locking groove 11 of the slider 4 is precisely matched with the main body of the tooling, and the rigid connection between the base 3 and the worktable 1 forms a stable adsorption cavity. After the vacuum equipment is started, the negative pressure causes the skin of the coating to be evenly extended and adhered, and the adhesive is firmly bonded by the heat-activated adhesive. After the operation is completed, the top constraint can be released by holding the handle 9 and vertically removing the baffle 3 8. The molded coating can be removed by sliding the slider 4 in the opposite direction and flipping the baffle.

[0027] like Figure 1 As shown,

[0028] It includes a workbench 1, and the upper space of the workbench 1 is provided with an adsorption fixture body 2 that is adapted to the shape of the H-shaped covering part. The H-shaped covering part is adsorbed and fixed to the adsorption fixture body 2.

[0029] The adsorption fixture body 2 is rigidly fixed to the workbench 1 surface through the base 3 connected to the bottom. The base 3 and the workbench 1 are connected by an array of threaded fastening components to achieve a detachable connection, so as to prevent the adsorption fixture body 2 from shifting during the operation.

[0030] The outer periphery of the adsorption fixture body 2 is designed to form an interference fit with the inner cavity of the H-shaped automotive body panel, making the adsorption more stable.

[0031] The adsorption fixture body 2 is symmetrically provided with axially sliding sliders 4 on both sides along its length direction. The sliders 4 have snap-fit ​​grooves 11 on their inner sides, which abut against the side of the adsorption fixture body 2 to ensure the sealing of the adsorption fixture body 2.

[0032] The movement trajectory of slider 4 is kept parallel to the central axis of the adsorption fixture body 2 to prevent slider 4 from shifting during movement.

[0033] Two hinged baffles, a first baffle 5 and a second baffle 6, are respectively hinged to the two ends of the adsorption fixture body 2. The inner working surfaces of the first baffle 5 and the second baffle 6 are provided with guide grooves 10 that match the movement trajectory of the slider 4 to ensure the sealing of the adsorption fixture body 2.

[0034] The hinge axis of baffle 5 and baffle 6 is set perpendicular to the plane of worktable 1. The top plane of slider 4 forms a continuous working surface with the corresponding surface of adsorption fixture body 2. The extension length of slider 4 exceeds the axial end face of adsorption fixture body 2. The lateral edges of baffle 5 and baffle 6 form a surface contact constraint with the end of slider 4, sealing the perimeter of adsorption fixture body 2 and limiting the H-shaped covering.

[0035] The top of the adsorption fixture body 2 is symmetrically equipped with mounting plates 7 perpendicular to the plane of the worktable 1. The lower edge of the mounting plate 7 forms a contact-type limiting structure with the upper surface of the slider 4. A detachable baffle 8 is provided between the two mounting plates 7. A handle 9 is provided on the upper surface of the baffle 8. The handle 9 is rigidly connected to the baffle 8 by at least two sets of fasteners, making the assembly and disassembly of the baffle 8 convenient and efficient. The working surface of the baffle 8 forms a mating contact with the top contour of the adsorption fixture body 2, which facilitates the movement of the slider 4 while also sealing the adsorption fixture body 2.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
