Description

Technical Field

[0001] This application relates to the technical field of processing and clamping of special profile workpieces, and particularly to a hidden clamping device. Background Art

[0002] Currently, clamping devices are widely used to fix workpieces to be processed to ensure processing accuracy and efficiency. With the rapid development of modern manufacturing, higher requirements are put forward for the automation and flexibility of processing equipment. While traditional clamping devices meet basic functions, problems such as complex structures and inconvenient operations are gradually exposed, restricting their application in certain specific scenarios. Therefore, it is of great significance to develop a clamping device with a simple structure, convenient operation and capable of adapting to various processing requirements.

[0003] In the prior art, in order to effectively clamp workpieces to be processed, the following several conventional means are usually adopted: fixing by simple bolts or manual levers, which is cumbersome and inefficient; using pneumatic or hydraulic-driven clamping devices, and completing the clamping process through the telescopic movement of cylinders or oil cylinders, but such devices often require a large installation space, often occupying the space of the workpiece on the processing table; in the conventional technology, in order to solve the occupation of the installation space of the clamping device before use, a space for placing the clamping device is opened on the processing table, but due to the limited range of the placed space, when facing special profile workpieces of different sizes, the clamping range and angle of the clamping device are limited, affecting the clamping effect on the workpiece, resulting in insufficient stability of the workpiece to be processed during processing.

[0004] In view of the above related technologies, it is necessary to propose a hidden clamping device to solve one of the above technical problems. Summary of the Invention

The pressing mechanism includes a plurality of support seats arranged in the adjustment frame, a multi-section rod sliding on the support seats, and a plurality of pressing blocks for pressing the workpiece to be processed. A combined block is arranged at the end of the multi-section rod, and the front end face of the combined block is connected to the rear end face of the pressing block. The pressing block is driven by the combined block of the multi-section rod sliding at the support seat to move out of the adjustment frame and press the workpiece to be processed on the processing table.

[0007] By adopting the above technical solution, the hidden pressing device can achieve stable pressing of the workpiece to be processed, and at the same time has a hidden function, reducing space occupation. Specifically, when the multi-section rod slides on the support seat, it can drive the pressing block to move out of the adjustment frame through the combined block at its end. This design enables the pressing block to be completely hidden inside the adjustment frame when not in use, thus avoiding the occupation of the space on the processing table and possible interference to the external environment. When it is necessary to press the workpiece to be processed, the sliding of the multi-section rod drives the combined block to act, and then the pressing block extends out of the adjustment frame and accurately acts on the surface of the workpiece to be processed, ensuring the stability and reliability of the pressing process. In addition, this structure also has flexibility and can adjust the pressing position and force according to actual needs, improving the adaptability and working efficiency of the device.

The extension abutting block is driven by the output end of the extension air cylinder to abut and press inside the hole of the workpiece to be processed.

[0009] By adopting the above technical solution, the pressing block can adapt to workpieces of different shapes. Especially for workpieces with hole structures, the extension abutting block can accurately extend into the hole under the drive of the extension air cylinder to achieve stable pressing of the internal structure of the workpiece, thereby improving the applicable range and pressing stability of the pressing device.
