Description

Technical Field

[0001] The utility model belongs to the technical field of radial drilling machines, in particular to a radial drilling machine with a replaceable clamp. Background Art

[0002] The radial drilling machine is a common metal cutting machine tool, which is widely used in the field of mechanical processing, and is particularly suitable for various hole processing operations on medium to large workpieces. Most radial drilling machines require the workpiece to be clamped and fixed during use, so that it can be firmly fixed during the workpiece processing process to prevent the workpiece from shifting. However, most of the common radial drilling machine fixtures are pre-fixed to the top of the base of the radial drilling machine, and are fixed by welding and other methods, resulting in the inability to routinely replace the workpiece clamping fixture in the later stage. In actual processing and use, depending on the different clamping and fixing requirements and the different shapes of the workpiece to be processed, the same fixture may not be able to achieve the optimal clamping convenience and clamping firmness, resulting in the inability to perform convenient operation or improve the clamping efficiency when the current fixture is used to clamp and fix the workpiece, thereby reducing the overall processing efficiency.

[0003] Secondly, the same fixture has different degrees of clamping firmness for workpieces of different shapes during use. Some special-shaped workpieces may not be clamped firmly, resulting in workpiece offset in subsequent processing operations, which in turn causes processing deviations or workpiece scrapping.

[0004] In summary, there are some problems in the use of radial drilling machines that cannot routinely replace the fixture, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
