Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for production of support plates, in particular to a clamping device for numerically controlled boring and milling of support plates. Background Art

[0002] The bearing plate is an important engineering component, mainly used in large buildings, roads, bridges, railways, tunnels and other engineering fields. In bridge construction, the bearing plate, as the main load-bearing element of the bridge, can effectively improve the durability and safety of the bridge. In the construction of large buildings, the bearing plate also plays an important role. It can bear the weight of the building, ensure the stability of the building, disperse the structural load, reduce the pressure on the foundation, and thus reduce the settlement and cracking of the foundation. Therefore, the bearing plate is a device that connects the pier or beam to the foundation. It is usually composed of two parts, the upper part is a movable bearing and the lower part is a fixed bearing. The movable bearing is usually made of steel plates, polyurethane and other materials, and has the function of bearing loads, The bearing plate has multiple functions such as load transfer and shock absorption, and the fixed bearing can effectively fix the pier or beam. In general, the bearing plate plays a vital role in the project and can effectively ensure the stability and safety of the building or bridge. The bearing plate needs boring and milling during the processing, and because boring and milling is a combined processing technology, it includes both milling and boring. It can complete multiple processing procedures at the same time, such as the processing of the center hole or the inner wall of the aperture and the plane contour. This multifunctional processing method enables boring and milling to efficiently handle various processing needs of the bearing plate, thereby ensuring To ensure the processing quality and accuracy, secondly, the bearing plate is a device connecting the pier or beam body with the foundation. It needs to bear a large load in the project. Therefore, the processing accuracy and surface quality of the bearing plate are required to be high. Boring and milling processing can accurately control the processing size and shape, achieve high-precision processing effects, and at the same time ensure the smoothness and accuracy of the processing surface to meet the use requirements of the bearing plate. In addition, boring and milling processing can also improve processing efficiency. Through computer control, boring and milling processing can realize automated and continuous production methods, reduce manual intervention and clamping time, thereby improving processing speed and production efficiency. Production efficiency, after completing the clamping task, it is difficult for the usual fixture to achieve the swing displacement of the support plate workpiece, which makes it difficult to handle complex scenes such as processing grooves with inclinations. For the intelligently adjusted CNC boring and milling cutter head, its high-speed rotation characteristics require a larger displacement space during the adjustment process, which undoubtedly increases the pressure on the cutter body and poses a severe challenge to the durability of the tool and the overall processing effect. For the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Utility Model Content
