[0001] This utility model belongs to the field of mechanical manufacturing technology, and specifically relates to a shaping fixture for an ultra-thin-walled cavity filter housing. Background Technology

[0002] A shell forming fixture is a type of mechanical equipment specifically designed for shaping shell-type parts. It is primarily used to correct deformations that occur during the manufacturing or use of the shell, ensuring that the shell's dimensional accuracy, shape accuracy, and surface quality meet design requirements.

[0003] As a key component of electronic communication equipment, the shape accuracy and surface quality of the filter housing directly affect the filter's performance and stability. Existing filter housing shaping fixtures often suffer from poor adaptability, complex operation, and low efficiency during use. Therefore, it is necessary to design a filter housing shaping fixture to effectively solve these technical problems. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model aims to provide an ultra-thin wall cavity filter housing shaping fixture, so as to improve the efficiency of the shaping fixture while enhancing its adaptability and ease of operation.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A shaping fixture for an ultra-thin-walled cavity filter housing includes a support frame. The support frame is equipped with a lifting mechanism that fixes the upper mold for shaping the filter housing and drives the upper mold to move vertically. A rotating mechanism is located on one side of the support frame, and a turntable is mounted on the rotating mechanism. The turntable has at least two sets of workstations. Driven by the rotating mechanism, the turntable can sequentially transport the workstations into the lifting mechanism. Each set of workstations is equipped with a mounting base mechanism for fixing a pair of bottom molds for shaping the filter housing.

[0007] Furthermore, the lifting mechanism includes a fixed base, and a vertically downward cylinder is mounted on the upper part of the fixed base via a motor support. A connecting seat for fixing the upper forming mold is provided at the lower end of the cylinder output shaft, and the connecting seat is mounted on the fixed base via a pair of linear guide rails.

[0008] Furthermore, a support base is provided on the fixing base located directly below the connecting base.

[0009] Furthermore, the rotating mechanism consists of a cam divider and a geared motor that drives the cam divider.

[0010] Furthermore, the mounting base mechanism includes a mounting base for fixing the bottom mold of the filter housing, at least two sets of limiting bolts, and springs corresponding to the limiting bolts; the front end of each limiting bolt is locked on the mounting base, and the spring is sleeved on the corresponding limiting bolt.

[0011] Furthermore, the mounting base is provided with at least four sets of guide shafts.

[0012] Furthermore, the turntable is equipped with an isolation plate, which isolates the various workstations.

[0013] Furthermore, a foot pad is provided below the support frame.

[0014] The beneficial effects of this utility model are as follows: By setting up a lifting mechanism and a rotating mechanism, this utility model realizes the rapid docking and separation of the upper and lower forming molds, as well as continuous operation of multiple stations, significantly improving forming efficiency; secondly, the upper and lower forming molds can be flexibly replaced according to the specific size, shape, and structure of the filter housing to be formed, making this tooling applicable to the forming of various types of ultra-thin-walled cavity filter housings, enhancing the tooling's versatility and adaptability; in addition, the combined design of the support base and spring not only effectively disperses and bears the enormous pressure during the forming process, ensuring the stability and safety of the forming process, but also avoids interference between the mounting base and the support base, ensuring the continuity and smoothness of the forming operation.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment 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 indicator will also change accordingly.

[0026] See Figure 1 As shown, a shaping fixture for an ultra-thin-walled cavity filter housing includes a support frame 1, on which a lifting mechanism 2 is mounted; a rotating mechanism 3 is located on one side of the support frame 1, and a turntable 4 is mounted on the rotating mechanism 3. The turntable 4 has six workstations. Driven by the rotating mechanism 3, the turntable 4 can sequentially transport the workstations into the lifting mechanism 2. The number of workstations on the turntable 4 is only one embodiment and is not intended to limit the scope of this application. In actual installation, the number can be set according to specific needs, but it should be noted that the number should not be less than two sets. Each workstation has a mounting base mechanism 5. During operation, see... Figure 2As shown, the bottom mold 9 for shaping the filter housing is fixed on the mounting base mechanism 5, and the top mold 8 for shaping the filter housing is fixed on the lifting mechanism 2. The filter housing is placed in the bottom mold 9. During shaping, the top mold 8 moves up and down under the drive of the lifting mechanism 2 to shape the filter housing placed in the bottom mold 9. It should be noted that the dimensions, shape, and structure of the top mold 8 and the bottom mold 9 shown in the figure are only schematic and do not represent the only or limited form in actual application. In actual application, the specific dimensions, shape, and structure of the top mold 8 and the bottom mold 9 will be flexibly designed according to the specific characteristics, material properties, and shaping process requirements of the housing to be shaped.

[0027] Further, see Figure 3 As shown, in this embodiment, the lifting mechanism 2 includes a fixed base 21. A vertically downward cylinder 23 is mounted above the fixed base 21 via a motor support 22. A connecting seat 24 for fixing the upper forming mold 8 is mounted at the lower end of the output shaft of the cylinder 23. The connecting seat 24 is mounted on the fixed base 21 via a pair of linear guide rails 25. A support seat 26 is mounted on the fixed base 21 directly below the connecting seat 24. During forming, the connecting seat 24 moves up and down under the cylinder 23, thereby driving the upper forming mold 8 to move up and down, thus realizing the forming operation.

[0028] Further, see Figure 2 As shown, in this embodiment, the rotating mechanism 3 consists of a cam divider 31 and a geared motor 32 that drives the cam divider 31. During installation, the cam divider 31 is fixed on the support frame 1, and the geared motor 32 is connected to the cam divider 31. In this embodiment, the geared motor 32 and the cam divider 31 are directly inserted. Since there are a total of 6 workstations in this embodiment, a 6-workstation cam divider 31 is used.

[0029] Further, see Figure 5 As shown, in this embodiment, the mounting base mechanism 5 includes a mounting base 51 for fixing the bottom mold 9 of the filter housing, two sets of limiting bolts 52, and springs 53 corresponding to the limiting bolts 52; during installation, refer to... Figure 4 and Figure 6As shown, the mounting base 51 is slidably mounted on the turntable 4. The limiting bolt 52 is slidably passed through the turntable 4 and its front end is locked onto the mounting base 51. The limiting bolt 52 connects the mounting base 51 to the turntable 4 and limits the maximum upward sliding distance of the mounting base 51. The spring 53 is sleeved on the corresponding limiting bolt 52 between the turntable 4 and the mounting base 51. At this time, without the action of external force, the spring 53 has a tendency to drive the mounting base 51 to move away from the turntable 4. It should be noted that the number of limiting bolts 52 is only one embodiment and is not intended to limit the scope of this application. In actual installation, other numbers can be set, such as 4, 6, etc.

[0030] Further, see Figure 5-6 As shown, in this embodiment, the mounting base 51 is provided with four sets of guide shafts 54, but not limited to four sets; when the mounting base 51 is installed on the turntable 4, the guide shafts 54 can slide through the turntable 4. By setting the guide shafts 54, the stability of the mounting base 51 sliding up and down in the turntable 4 is improved.

[0031] Further, see Figure 1-2 As shown, in this embodiment, the turntable 4 is provided with an isolation plate 6, which is used to isolate the various workstations.

[0032] For further details, please refer to [link / reference]. Figure 1-2 As shown, in this embodiment, a foot 7 is provided below the support frame 1.

[0033] The working principle of this utility model is as follows:

[0034] Before shaping, after selecting the appropriate shaping mold according to the specific size, shape and structure of the filter housing, the upper shaping mold 8 is fixed on the connecting seat 24, and the bottom shaping mold 9 is fixed on the mounting seat 51 in each station in sequence. Then, the housing to be shaped is placed on the bottom shaping mold 9 in sequence.

[0035] During the shaping process, the turntable 4 rotates under the drive of the rotating mechanism 3, sequentially transporting the workstations to the lifting mechanism 2. Specifically, the shells to be shaped placed in the shaping bottom mold 9 are sequentially transported to the lifting mechanism 2. After a workstation is sent into the lifting mechanism 2, the rotating mechanism 3 temporarily stops driving the turntable 4. During this temporary stop, the shaping upper mold 8 moves downward under the drive of the cylinder 23 to shape the shells to be shaped. After the shaping is completed, it moves upward and resets to the initial position under the drive of the cylinder 23. Then, the rotating mechanism 3 drives the turntable 4 to rotate again, thus transporting the next workstation to the lifting mechanism 2, thereby achieving continuous shaping operations.

[0036] During the shaping process, when the upper shaping mold 8 is pressed down, the mounting base 51 will move downward under force and abut against the support base 26. The support base 26 can effectively distribute and bear the huge pressure from the upper shaping mold 8, ensuring the stability and safety of the entire shaping process. When the upper shaping mold 8 begins to reset, the mounting base 51 loses the downward pressure and is driven to move upward to reset under the action of the spring 53. This avoids interference between the lower end of the mounting base 51 and the support base 26 during the rotation of the turntable 4 driven by the rotating mechanism 3, which would affect the shaping operation.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
