Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a quick clamping device for numerical control processed parts. Background Art
[0002] In the field of mechanical manufacturing, parts need to be clamped when they are processed, and then fixed to CNC processing equipment, and finally CNC processing is performed. In CNC processing, the workpiece needs to be clamped and fixed. It can be seen that alignment and clamping are essential processes for processing each part. When fixing, a positioning fixture is needed. After the workpiece is fixed by the fixture, it is convenient for the processing of the workpiece. In the process of CNC processing, in addition to the structural parts with relatively regular structures, some irregular-shaped parts with irregular shapes and structures are often involved, such as Figure 1 The special-shaped part shown in the figure has a plum blossom-shaped structure. The existing clamping method is adopted. After the part is aligned, the clamping plate is pressed on the part, and then the part under the clamping plate is fixed on the working table of the CNC machine tool by bolts and the like. The installation and fixing method is as follows: Figure 2 As shown. With the existing clamping method of the pressure plate, since the pressure plate presses part of the structure of the part, in the CNC processing stage, it is necessary to ensure that points A and B on the outside of the workpiece are on the same horizontal line, which will waste a lot of clamping time and increase labor costs; and during processing, it is necessary to avoid the pressure plate, and it can only be processed in sections. After one processing, it can only process points C and D on the outside of the workpiece, so it is necessary to perform secondary clamping, and then the workpiece can be processed between points C and D on the outside. With the existing clamping method of the pressure plate, it is impossible to complete the CNC processing of the part at one time, and it is necessary to perform segmented processing, so it is necessary to disassemble the pressure plate, change the position of the part, and then use the pressure plate to clamp and process after realignment. It can be seen that the use of the existing clamping method of the pressure plate not only wastes a lot of clamping time, increases manpower and material costs, and leads to low processing efficiency; at the same time, the use of multiple alignment clamping methods is also likely to cause the processed special-shaped parts to fail to meet the use requirements, and does not meet the economic requirements of improving quality and efficiency.
[0003] Bench vise, also known as vice, is the most widely used general clamping tool. Usually, vise can only clamp parts with two parallel planes. For example, when it comes to cylindrical workpieces, it cannot be clamped firmly, which can easily cause the cylindrical workpiece to fall during processing and cause danger. In addition, in the actual processing process, special-shaped parts with plum blossom-shaped appearance and structure are small-batch products. In order to meet the economic requirements of improving quality and efficiency, special fixtures cannot be designed for such structures. Therefore, in order to meet the processing needs of special-shaped parts and existing conventional products, the existing vise is improved to provide a clamping device with good practical performance. The clamping device can not only meet the processing needs of special-shaped parts, but also meet the processing needs of existing conventional products. Utility Model Content
