Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clamps, in particular to a quick replacement type clamp device. BACKGROUND

[0002] In modern industrial production, processing and various mechanical operation processes, clamps play a crucial role. It is used to fix workpieces to ensure that workpieces can maintain stable position and posture in processing, assembly, detection and other processes to meet the high-precision process requirements. Traditional clamp devices often have many shortcomings. On the one hand, the clamping mechanism is usually single in structure, and has poor adaptability to workpieces of different sizes. When replacing the workpiece for processing, a lot of time is spent on adjusting the clamp, which seriously affects the production efficiency. For example, some simple single-side clamping type clamps can only adapt to workpieces within a specific width range. Once the size of the workpiece changes greatly, it cannot be effectively clamped, and even the workpiece may be damaged. On the other hand, during the processing, especially in the process of cutting, grinding, drilling and other processes that generate debris, a large amount of debris is easily accumulated around the clamp device, which is difficult to clean. Not only will it affect the accuracy and service life of the clamp itself, but also it may mix into the subsequent processing link, causing product quality problems. Moreover, the connection stability of the existing clamp device with the workbench or other equipment needs to be improved. After a long time of use or being subjected to a certain external impact, displacement and loosening may occur, further reducing the processing accuracy. Therefore, it is an urgent problem in the current technical field to develop a clamp device that can quickly replace workpieces, has efficient dust collection function and stable connection.
