The metal shell and plastic shell to be crimped are fixed. A special spindle and an over-positioning coupling are used to fix the product. The spindle is then connected to an irregular locking clamp to fix the product. The existing irregular metal and plastic shell pressing structure still has the following problems: Some irregularly shaped metal and plastic shell pressing structures lack adjustable support components, flexible transmission structures, elastic buffer components, and stable positioning structures, which affects the adaptability to workpieces of different sizes and the pressing alignment accuracy. This is not conducive to reducing component wear and operational impact, resulting in a high pressing failure rate, a narrow range of equipment applications, and poor durability. Utility Model Content
[0003] The purpose of this utility model is to provide a pressing structure for irregularly shaped metal and plastic shell, in order to solve the problem that the existing processing and molding process uses all manual fixing and manual pushing of bearings and bearing rollers, resulting in a high rate of damage, impact, deformation and defect of the fixed metal shell.
[0004] To achieve the above objectives, a pressing structure for pressing irregular metal and plastic shell is provided, including a device body, wherein the device body includes a limiting shaft fixing plate, a limiting shaft, a positioning pad, an irregular chuck, a bearing shaft, and a bearing bracket; The limiting shaft fixing plate is fixed to the device body, the limiting shaft is rotatably mounted on the limiting shaft fixing plate, the positioning pad is set at the corresponding position of the limiting shaft and the device body, the irregular chuck is used to clamp irregular metal parts, the bearing shaft is connected to the irregular chuck, and the bearing bracket is fixedly mounted on the device body to support the bearing shaft.
[0005] According to the aforementioned irregular metal and plastic shell pressing structure, the bearing shaft can rotate or move axially.
[0006] According to the aforementioned irregular metal and plastic shell pressing structure, the positioning pad is made of elastic material and is used to buffer the impact during the pressing process.
[0007] According to the aforementioned irregular metal and plastic shell pressing structure, the device body is provided with a positioning groove or clamp for fixing the plastic shell.
[0008] According to the aforementioned irregular metal and plastic shell pressing structure, the bearing bracket is an adjustable structure to accommodate irregular metal parts of different sizes.
[0009] The above-mentioned solution has the following beneficial effects: This patented device, in conjunction with a movable bearing shaft, an elastic positioning pad, a plastic shell fixing structure, and an adjustable bearing bracket, allows for the use of metal parts of different sizes. The adjustable bracket adapts to the flexible movement of the bearing shaft and the support of the bracket, ensuring precise alignment. The elastic positioning pad buffers impacts and reduces wear. All components work together to improve the stability, accuracy, and durability of the crimping process, reducing the risk of defects and facilitating reliable crimping.

[0013] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0014] Reference Figure 1-7 This utility model discloses a pressing structure for irregularly shaped metal and plastic shell, comprising a device body 1. The device body 1 includes a limiting shaft fixing plate 2, a limiting shaft 3, a positioning pad 4, an irregularly shaped clamp 5, a bearing shaft 6, and a bearing bracket 7. The limiting shaft fixing plate 2 is fixed to the device body 1, the limiting shaft 3 is rotatably mounted on the limiting shaft fixing plate 2, the positioning pad 4 is disposed at corresponding positions on the limiting shaft 3 and the device body 1, the irregularly shaped clamp 5 is used to clamp irregularly shaped metal parts, the bearing shaft 6 is connected to the irregularly shaped clamp 5, and the bearing bracket 7 is fixedly mounted on the device body 1 to support the bearing shaft 6. In use, this pressing structure for irregularly shaped metal and plastic shell integrates the limiting shaft fixing plate 2, the limiting shaft 3, the positioning pad 4, the irregularly shaped clamp 5, and the bearing shaft 6 through the device body 1. The core components, such as the bearing shaft 6 and bearing bracket 7, and the limiting shaft fixing plate 2, provide a stable mounting base for the limiting shaft 3. Together with the positioning pad 4, they can achieve precise positioning and buffer protection during the rotation of the limiting shaft 3, reducing frictional wear between components. The bearing bracket 7 provides reliable support for the bearing shaft 6 connected to the irregular chuck 5, ensuring the stability and coaxiality of the bearing shaft 6 when driving the irregular chuck 5. This, in turn, ensures the stable clamping and crimping alignment accuracy of the irregular metal parts by the irregular chuck 5. The overall structure has clear division of labor and compatible connections among its components, effectively improving the structural stability, operational accuracy, and component durability during the crimping process of irregular metal parts and plastic shells, reducing the risk of crimping deviation, and providing strong support for efficient and reliable crimping operations.
[0015] The bearing shaft 6 rotates or moves axially. The positioning pad 4 is made of elastic material to buffer the impact during the pressing process. The device body 1 is equipped with a positioning groove or clamp for fixing the plastic shell. The bearing bracket 7 is an adjustable structure to adapt to irregular metal parts of different sizes. During use, the bearing shaft 6 can achieve a compound motion of rotation and axial movement, which greatly improves the operational flexibility of the irregular chuck 5 for irregular metal parts and can adapt to diverse pressing angle and position requirements. The positioning pad 4 is made of elastic material, which can effectively buffer the instantaneous impact during the pressing process, reduce the rigid collision loss between the limiting shaft 3 and the device body 1, and extend the service life of the components. The positioning groove or clamp on the device body 1 can firmly fix the plastic shell and ensure the relative position accuracy of the plastic shell and the irregular metal parts during pressing. The bearing bracket 7 is designed as an adjustable structure, which can be adjusted to adapt to irregular metal parts of different sizes, significantly expanding the applicability of the device. Through the functional optimization and synergistic cooperation of each component, the stability, adaptability and safety of the pressing operation are further improved, and the risk of pressing defects caused by size differences or operational impacts is reduced.
[0016] Working principle: The plastic shell is fixed by the positioning groove or clamp on the device body 1 to ensure its stable position; according to the size of the irregular metal part to be pressed, the bearing bracket 7 is adjusted to the appropriate position, and then the irregular metal part is clamped and fixed by the irregular chuck 5. The limiting shaft 3 rotates under the support of the limiting shaft fixing plate 2, which drives the associated bearing shaft 6 to rotate or move axially in sync, thereby driving the irregular chuck 5 to clamp the irregular metal part and move towards the plastic shell to complete the pressing action. During this process, the positioning pad 4 set at the corresponding position of the limiting shaft 3 and the device body 1 can buffer the impact generated by the pressing and reduce the rigidity loss between the parts, while the stable support of the bearing bracket 7 on the bearing shaft 6 ensures the alignment accuracy of the irregular metal part and the plastic shell during the pressing process, and finally realizes the reliable pressing of the irregular metal and the plastic shell.
[0017] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
