Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, and particularly relates to a positioning and adjustment structure of a component pre-assembly workpiece pressing device. Background Art

[0002] Component pre-assembly refers to the process of assembling multiple components or parts into a whole in advance during the production and manufacturing process, so as to facilitate subsequent production and manufacturing. Pre-assembly can reduce assembly time and labor costs, improve production efficiency, and ensure product consistency and quality stability. Pre-assembly usually requires strict quality control and testing of each component and part to ensure that they meet the specifications and requirements. Pre-assembly can be applied to various industrial fields, including the automotive, mechanical, and electronics industries;

[0003] The workpiece pressing device in assembly is a device used to apply pressure to parts or components for assembly or fixation. It is usually used to ensure that the parts are correctly installed and the required connection force or fastening force is achieved. The workpiece pressing device can provide pressure through mechanical, hydraulic, or pneumatic means and use appropriate fixtures or dies to hold the position and orientation of the workpiece.

[0004] In the prior art

[0005] The positioning device for pressing uses a fixed structure. Its main feature is a fixed design. A fixture is used to fix the workpiece in a predetermined position and orientation. The fixture is made of rigid materials and includes clamping blocks and clamping arms, which are used to ensure that the position and attitude of the workpiece remain unchanged. This will limit the flexibility during the assembly process. Different-sized workpieces require different positioning methods, and the lack of adjustment function may lead to the inability to adapt to these changes and the inability to meet diverse assembly requirements, resulting in the need for additional assembly equipment or manual adjustment, increasing time and costs. For this reason, we propose a positioning and adjustment structure of a component pre-assembly workpiece pressing device to solve the above problems. Content of the Utility Model

The pressing ring is sleeved on the surfaces of a plurality of triggering seats. Inclined surfaces are opened on the contact surfaces between the pressing ring and the triggering seats. Threaded rollers are arranged on both sides of the pressing ring. One end of the threaded roller penetrates through the pressing ring and extends into the workbench. The threaded roller is threadedly connected to the workbench. The threaded roller is rotatably connected to the pressing ring.

[0009] Preferably, the guiding platform is arranged in the guiding chamber, and the guiding platform is slidably connected to the inner wall of the guiding chamber. The guiding platform coincides with the axis of the workbench, and the bottom of the guiding platform is fixedly connected to the connecting cylinder.

[0010] Preferably, the plurality of mounting grooves are evenly distributed around the axis of the guiding platform.

[0016] By adopting the above technical solutions, the beneficial effects obtained by the present utility model are:

[0017] In this utility model, the circular workpiece base is placed between multiple positioning plates. Then, the pressing ring is driven to move downward. Due to the inclined contact surface between the pressing ring and the trigger seat, when the trigger seat reaches the limit position supported by the telescopic spring and cannot move downward, finally, the trigger seats can only move closer to each other instead of moving downward. Cooperating with the positioning plates, the fixation of the workpiece is completed. This design enables the device to adapt to workpieces of different sizes and shapes, improving its applicability and flexibility. The settings of the telescopic spring and the reset spring enable the trigger seat to remain in close contact with the pressing ring, preventing the components from moving, reducing errors caused by vibration or deformation during the assembly process, ensuring the overall stability of the device, thus achieving precise operation of the workpiece. At the same time, the device can adapt to workpieces of different sizes and shapes, expanding its applicable range and flexibility. The operation is simple, improving the assembly efficiency, making the device perform excellently during the pre-assembly process of the workpiece and providing support for industrial production.

[0028] Further, a pressure ring 301 is provided in the control component 3. The pressure ring 301 is sleeved on the surfaces of multiple trigger seats 207. The pressure ring 301 coincides with the axis of the workbench 1. Inclined surfaces 208 are provided on the contact surfaces between the pressure ring 301 and the trigger seats 207.
