Description

Technical Field

[0001] This utility model belongs to the field of pressing tooling, specifically relating to a convenient ceiling pressing tooling. Background Technology

[0002] With the rapid development of the machinery industry, people are paying more and more attention to product quality. In the modern automobile manufacturing process, the roof, as an important part of the body structure, not only serves the function of appearance design, but also plays a key role in the sealing, sound insulation, safety and ride comfort of the whole vehicle.

[0003] Currently, in actual production, ceiling assembly still mainly relies on manual operation or semi-automated equipment. For example, a common practice is to use a rubber or metal hammer to press the first assembly into the second assembly, or to use a simple combination of hydraulic cylinders and clamps to complete the pressing action. However, this method has many shortcomings:

[0004] 1. Difficulty in controlling the pressing force: Manual tapping cannot accurately control the pressing force, which can easily lead to incomplete or excessive pressing, resulting in loose assembly or damage to parts.

[0005] 2. Uneven stress affects assembly quality: Due to the lack of effective contour support and uniform force application mechanism, traditional pressing method often causes local stress concentration, which leads to problems such as assembly deformation and cracking, and thus affects the overall vehicle quality.

[0006] 3. Low operating efficiency and high labor intensity: Manual operation is time-consuming and requires repeated adjustments to position and force, which increases the labor intensity of operators and is not conducive to achieving efficient and standardized production. Utility Model Content

[0024] In the aforementioned convenient ceiling pressing fixture, the anti-detachment cylinder and the anti-detachment block are provided. The anti-detachment cylinder is installed at the top of the frame, and a locking shaft is connected to the output end of the anti-detachment cylinder. The anti-detachment block is installed on the movable frame, and an anti-detachment hole is installed on the anti-detachment block. The locking shaft is movably inserted into the anti-detachment hole to restrict the movement of the movable frame relative to the frame.

[0025] In the aforementioned convenient ceiling pressing fixture, a first limiting block and a second limiting block are respectively provided on the movable frame and the reference platform. The first limiting block can be moved to abut against the second limiting block when the movable frame moves closer to the reference platform.

[0026] In the aforementioned convenient ceiling pressing tool, the anti-detachment component includes:

[0027] An extension bracket is detachably mounted on the fixed frame and extends to one side of the contour base;

[0028] The system includes a positioning cylinder and a clamping cylinder.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) The present invention provides a convenient ceiling pressing fixture. The upper mold mechanism and the guide mechanism pre-drive the first assembly and the second assembly to achieve accurate fitting, which effectively prevents the assembly from shifting or falling off during the pressing process, thereby improving the assembly quality and consistency. At the same time, the locking mechanism locks the upper mold mechanism, which ensures the stability of the entire pressing operation process and avoids relative displacement or interference between the pressing plate and the contour seat. As the pressing plate contacts and acts on the surface of the first assembly, the pressure distribution becomes more uniform, avoiding assembly damage or deformation caused by local stress concentration. The whole process is automated, which improves work efficiency and ensures that the final ceiling quality meets the required usage requirements.

[0034] (2) The locking shaft is inserted into the anti-detachment hole of the anti-detachment block by the anti-detachment cylinder, which ensures the smoothness and stability of the first assembly when it is placed on the contour seat. It also improves the safety of the entire operation process and avoids the risk of the moving frame shaking or even falling off accidentally.

[0035] (3) By relying on the cooperation of the connecting plate and the locking pin, the mobile frame and the fixed frame can be quickly installed and disassembled, which greatly facilitates the maintenance or replacement of the parts on them. Attached Figure Description

[0048] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0050] like Figures 1 to 6 As shown, this utility model discloses a convenient ceiling pressing tool for pressing a first assembly on a ceiling onto a second assembly, so that the two are in an interference fit. It includes a frame 1, a positioning mechanism 2, an upper mold mechanism 3, a pressing mechanism 4, a guiding mechanism 5, and a locking mechanism 6.

[0051] The frame 1 is equipped with a reference platform 10; a positioning mechanism 2 is set on the reference platform 10 and is used to confine the second assembly within the frame 1; an upper mold mechanism 3 and a pressing mechanism 4 are both located above the positioning mechanism 2. The upper mold mechanism 3 includes several contouring seats 30 and anti-detachment components 31. The contouring seats 30 extend into the first assembly, and the anti-detachment components 31 are located at the periphery of the contouring seats 30 to fix the first assembly onto the contouring seats 30; the pressing mechanism 4 is connected to the upper mold mechanism 3 and includes a pressing plate 40 located between the contouring seats 30. When the upper mold mechanism 3 moves the first assembly to press against the second assembly, the pressing plate 40 can press the first assembly on the contouring seats 30 onto the second assembly; a guide mechanism 5 is set on the frame 1 and is used to guide the upper mold mechanism 3 to move vertically and press against the positioning mechanism 2; a locking mechanism 6 is used to restrict the movement of the upper mold mechanism 3 to prevent the pressing plate 40 from interfering with the contouring seats 30 when it moves.

[0052] In this embodiment, the canopy mainly consists of a first assembly (not shown in the figure) and a second assembly (not shown in the figure). In conventional assembly methods, the first assembly is usually pressed into the second assembly manually using auxiliary tools (such as a metal hammer) (equivalent to an interference fit assembly mode), thus fixing the two together. This embodiment, however, automates the pressing operation of the assemblies. Specifically, as shown... Figures 1 to 6 As shown, firstly, a worker or robot can place the second assembly to be assembled on the reference platform 10 and fix it by the positioning mechanism 2 to ensure that the second assembly is stable and does not shift during the pressing process. At the same time, the first assembly to be assembled is initially positioned by a number of contour seats 30 (designed according to the internal contour of the first assembly). As the anti-detachment component 31 extends into the first assembly, the stability of the first assembly is ensured. It should be noted that the cooperation between the contour seats 30 and the anti-detachment component 31 ensures that the fixed position of the first assembly is aligned with that of the second assembly (i.e., set with a height difference), which helps to ensure the accuracy and stability of the subsequent pressing between the two assemblies. As the upper mold mechanism 3 moves downward along the vertical direction set by the guide mechanism 5 (i.e., along the vertical direction set by the guide mechanism 5), the second assembly is further positioned. Figure 1(Moving vertically downwards), the pressing mechanism 4 moves downwards synchronously with the upper mold mechanism 3 without relative movement between them. When the first assembly on the contour seat 30 is pre-fitted to the second assembly (serving the function of alignment and correction), once everything is ready, the aforementioned anti-detachment component 31 can loosen its clamping and fixing of the first assembly. During the pressing process of the pressing plate 40 completing the main pressing action, in order to avoid interference or misalignment between the pressing plate 40 and the contour seat 30 due to relative movement, the locking mechanism 6 is activated and locks the position of the upper mold mechanism 3. This ensures that the upper mold mechanism 3 will not move unexpectedly during the pressing action of the pressing plate 40 (i.e., the pressing plate 40 moves relative to the upper mold mechanism 3 to perform the pressing action). This provides stability for the pressing plate 40 to gradually and evenly press the first assembly onto the second assembly, making it enter the interference fit state. Throughout the pressing process, the guide mechanism 5 always plays a guiding role to ensure that the upper mold mechanism 3 moves smoothly in the vertical direction, improving the pressing accuracy and reducing the risk of off-center loading. It can be seen that the entire pressing process of this pressing fixture is automated. The upper mold mechanism 3 is used to achieve the initial contact between the first assembly and the second assembly, avoiding misalignment and assembly deviation. At the same time, the locking mechanism 6 is used to lock the upper mold mechanism 3, ensuring that the pressing plate 40 is more evenly distributed on the surface of the first assembly during the pressing process, avoiding local stress concentration, significantly reducing the risk of assembly deformation or breakage, and improving assembly quality.

[0053] The upper mold mechanism 3 includes: an upper mold cylinder 32 and a moving frame 33. The upper mold cylinder 32 is installed at the top of the frame 1, and the output end of the upper mold cylinder 32 is connected to the moving frame 33 to drive the moving frame 33 closer to or away from the reference platform 10; a fixed frame 34 and a connecting plate 35. The fixed frame 34 is located below the moving frame 33. Several contour seats 30 and anti-detachment parts 31 are installed on the fixed frame 34. The connecting plate 35 is detachably connected to the fixed frame 34. A connecting seat 330 is provided on the moving frame 33. The end of the connecting plate 35 away from the fixed frame 34 extends into the connecting seat 330 and is fixedly connected by a locking pin 331; and several buffer pads 36 are provided between the moving frame 33 and the fixed frame 34 to buffer the clamping force between the first assembly and the second assembly.

[0054] like Figures 1 to 5 As shown, in this embodiment, the upper mold cylinders 32 are symmetrically arranged at the top of the frame 1 to ensure that the driven moving frame 33 can drive the fixed frame 34 to always maintain a horizontal posture. Figure 1 Vertical lifting or lowering ensures smoothness and stability during pressing. After the first and second assemblies are accurately positioned, the upper mold cylinder 32 can drive the moving frame 33 along... Figure 1Moving vertically, since the connecting plate 35 is fixedly connected to the connecting seat 330 via the locking pin 331, the fixing frame 34 also moves down synchronously with the moving frame 33. This causes the first assembly, fixed by the contour seat 30 and the anti-detachment component 31, to gradually move closer to the second assembly to achieve initial contact. In this structure, the connecting plate 35 and the connecting seat 330 can be quickly disassembled and assembled via the locking pin 331, allowing the fixing frame 34 and its contour seat 30 and anti-detachment component 31 to be quickly replaced, adapting to different vehicle roof structures, significantly improving the tooling's versatility and changeover efficiency, while also providing convenience for the maintenance and replacement of parts on the moving frame 33. In addition, the buffer pad 36 is placed between the moving frame 33 and the fixing frame 34 to absorb impact energy in the initial stage of pressing, preventing assembly deformation or breakage due to sudden loading. This is especially suitable for lightweight materials sensitive to pressing impact (such as carbon fiber, ABS, etc.). For this reason, the upper mold mechanism 3 drives the first assembly to achieve flexible contact with the second assembly, preventing the product from being damaged during the pressing process and affecting quality.

[0055] The locking mechanism 6 includes: a mounting base 60, which is set on the movable frame 33, and a locking cylinder 61 is detachably connected to the mounting base 60; a locking block 62, which is set on the side wall of the fixed frame 34, and a locking hole 620 is opened in the locking block 62, and the output end of the locking cylinder 61 is movably inserted into the locking hole 620.

[0056] like Figure 5 As shown, when the upper mold cylinder 32 drives the moving frame 33 and the fixed frame 34 to move vertically, so that the first assembly is flexibly pressed against the second assembly, after the detection sensor (not shown in the figure) in the frame 1 detects that the two assemblies are accurately aligned, the locking cylinder 61 can receive the corresponding signal and drive its output end to extend into the locking hole 620. Since the contour seat 30 and the anti-detachment component 31 are both installed on the fixed frame 34, this locking function helps to avoid accidental displacement caused by external vibration or cylinder pressure fluctuation, ensuring that the pressing action is safe and reliable, especially suitable for high-precision assembly occasions.

[0057] The pressing mechanism 4 also includes: a support base 41, symmetrically arranged on the movable frame 33, with a pressing cylinder 42 penetrating the frame 1 connected to the support base 41; a receiving plate 43, one end of which is connected to the output end of the pressing cylinder 42, and the other end is connected to a receiving frame 44, with the pressing plate 40 detachably connected to the receiving frame 44.

[0058] like Figure 3 and Figure 5 As shown, in this embodiment, the pressing cylinder 42 can be mounted on the bearing seat 41 using bolts, screws, locking pins, and other components, simplifying the assembly process and facilitating subsequent maintenance and disassembly / replacement; Figure 5As shown, several contour seats 30 are distributed around the periphery of the support frame. As the first and second assemblies flexibly adhere together, and the locking cylinder 61 completes its locking function on the fixing frame 34, the pressing cylinder 42 drives the receiving seat and the receiving frame 44 to move together towards the reference platform 10. This allows the pressing plate 40 to contact the surface of the first assembly along a direction parallel to the contour seats 30 and begin applying uniform pressure. As the pressing cylinder 42 continues to press down, the pressing plate 40 pushes the first assembly to gradually adhere to the second assembly, achieving an interference fit. Because the pressing plate 40 is arranged between the contour seats 30, it ensures uniform distribution of the pressing force and avoids localized stress concentration. It should be noted that the pressing plate 40 in this embodiment uses a detachable (screw, bolt) connection method, allowing for quick replacement according to different vehicle models and assembly structures, significantly improving the tooling's versatility and flexible production capabilities, and reducing changeover costs.

[0059] The guiding mechanism 5 includes a guide rod 50 and a guide sleeve 51. The guide rod 50 is vertically connected to the top of the frame 1 and the reference platform 10 respectively. An extension plate 332 is formed at the edge of the movable frame 33. The guide sleeve 51 is detachably connected to the extension plate 332 and movably sleeved on the guide rod 50.

[0060] like Figure 1 , Figure 3 as well as Figure 6 As shown, this embodiment effectively restricts the movement freedom of the movable frame 33 through the sliding fit between the guide rod 50 and the guide sleeve 51, allowing it to move only in the vertical direction. This significantly improves the operating accuracy and repeatability of the upper mold mechanism 3, making it suitable for complex working environments such as frequent starts and stops and variable loads. It can maintain good guiding performance for a long time and ensure consistent pressing quality. In addition, an extension plate 332 is provided at the edge of the movable frame 33 to install the guide sleeve 51, which increases the guiding contact area, improves the structural rigidity and anti-eccentric load capacity of the overall guiding system, and prevents shaking or jamming caused by external forces. Preferably, the guide sleeve 51 and the extension plate 332 can be assembled by an interference fit. Of course, a detachable (screw or bolt) connection can also be used to facilitate daily inspection, cleaning, or replacement of worn parts, reduce equipment maintenance costs, and extend service life.

[0061] The guide mechanism 5 also includes a positioning post 52 and a positioning sleeve 53. The positioning post 52 is installed on the reference platform 10, and the positioning sleeve 53 is connected to the movable frame 33. The positioning post 52 is movably inserted into the positioning sleeve 53.

[0062] Furthermore, such as Figure 1 , Figure 3 as well as Figure 6As shown, in this embodiment, the positioning pin 52 and the positioning sleeve 53 are both installed and fixed by screws or bolts. When the upper mold cylinder 32 drives the moving frame 33 and the fixed frame 34 to approach the reference platform 10, as the positioning pin 52 is inserted into the positioning sleeve 53, it not only plays a guiding role, but also achieves precise positioning of the moving frame 33, ensuring that the position of each pressing action remains consistent, and improving assembly consistency and repeatability.

[0063] Similarly, in this embodiment, a first limiting block 333 and a second limiting block 13 are respectively provided on the movable frame 33 and the reference platform 10, such as... Figure 5 and Figure 6 As shown, the first limiting block 333 can move and abut against the second limiting block 13 when the moving frame 33 approaches the reference platform 10. It is precisely by utilizing the physical contact between the first limiting block 333 and the second limiting block 13 that the downward limit position of the moving frame 33 can be effectively controlled, ensuring that the termination point of each pressing action is consistent. This not only ensures the safety of pressing but also improves the consistency and repeatability of assembly.

[0064] The anti-detachment component 31 includes: an extension bracket 310, which is detachably mounted on the fixing frame 34 and extends to one side of the contour base 30; an adjustment cylinder 311 and a clamping cylinder 312. The adjustment cylinder 311 is mounted on the extension bracket 310, and the output end of the adjustment cylinder 311 is connected to a contour block 311a to adapt to the first assembly of different specifications; the clamping cylinder 312 is mounted on the back side of the contour block 311a, and the contour block 311a has a through groove 311b. The output end of the clamping cylinder 312 is connected to a clamping block 312a that passes through the through groove 311b to restrict the first assembly on the contour block 311a.

[0065] like Figure 3 and Figure 4 As shown, the extension bracket 310 in this embodiment can also be installed on the fixed frame 34 using screws or bolts. The difference is that the extension bracket 310 extends beyond the fixed frame 34 to adapt to the specifications and shape of the first assembly. That is, by adjusting the cylinder to drive the contour block 311a to move, it is adjusted to a suitable relative position with the contour seat 30, so as to adapt to the first assembly with different shapes and sizes, significantly improving the clamping accuracy and applicability, and avoiding clamping failure due to structural mismatch. When the first assembly to be pressed is placed on the contour seat 30 and the contour block 311a, the clamping cylinder 312 drives the clamping block 312a to form a stable clamping force on the first assembly. The through groove 311b provides sufficient displacement space for the movement of the clamping block 312a, effectively preventing it from sliding or falling off during the pressing process, and ensuring the safety and reliability of the assembly process.

[0066] This solution also includes an anti-detachment cylinder 11 and an anti-detachment block 12. The anti-detachment cylinder 11 is installed at the top of the frame 1. The output end of the anti-detachment cylinder 11 is connected to a locking shaft 110. The anti-detachment block 12 is installed on the movable frame 33, and an anti-detachment hole 120 is installed on the anti-detachment block 12. The locking shaft 110 is movably inserted into the anti-detachment hole 120 to restrict the movement of the movable frame 33 relative to the frame 1.

[0067] Furthermore, such as Figure 2 and Figure 3 As shown, after the pressing fixture completes the pressing operation, the upper mold cylinder 32 can drive the moving frame 33 and the fixed frame 34 to return to their original positions. Figure 1 In the initial position shown, the locking shaft 110 is driven by the anti-detachment cylinder 11 to insert into the anti-detachment hole 120, thereby achieving precise locking of the moving frame 33. On the one hand, this ensures the stability and accuracy of the first assembly when it is placed on the contour seat 30 and the contour block 311a. On the other hand, it effectively prevents the risk of the moving frame 33 and the fixed frame 34 falling off due to mechanical vibration, thus improving the safety and reliability of the entire tooling during operation.

[0068] The positioning mechanism 2 includes: a contouring base 20, which is mounted on the frame 1 and is used to support the second assembly to be pressed together; and a rotary cylinder 21, which is located at the periphery of the contouring base 20 and has a flipping block 210 connected to its output end. The flipping block 210 is used to press the second assembly onto the contouring base 20.

[0069] like Figure 6 As shown, the positioning mechanism 2 in this embodiment mainly consists of a contouring base 20 and a rotary cylinder 21. When the second assembly to be pressed is placed on the contouring base 20, the rotary cylinder 21 can drive the flipping block 210 to gradually approach and press against the outer wall of the second assembly. At the same time, it can also move away from the pressing area when not in operation, avoiding positional interference during the placement of the second assembly. This facilitates operation and ensures the required pressing quality.

[0070] Preferably, in this embodiment, a threaded sleeve 14 is also installed at the top of the frame 1. A limiting post 15 is threadedly connected to the inner thread of the threaded sleeve 14. During the lifting process driven by the upper mold cylinder 32, the movable frame 33 can move and abut against the limiting post 15 to ensure that the entire upper mold mechanism 3 remains in the same position during repeated resets, facilitating the positioning and placement of the first assembly by an external robot after gripping it. Of course, the extension and retraction length of the limiting post 15 within the threaded sleeve 14 can be adjusted through the threaded connection to suit different application scenarios.
