Description

Technical Field

[0001] The utility model relates to the technical field of drilling machine tools, in particular to a fixing fixture of a drilling machine tool. Background Art

[0002] A drilling machine is a machine that uses a tool that is harder and sharper than the target object to create cylindrical holes or holes in the target object through rotary cutting or rotary extrusion. It is commonly used in manufacturing fields such as steel, automobile, and shipbuilding, where drilling machines can achieve precise punching and drilling operations to meet various manufacturing needs.

[0003] Drilling machines nowadays also have many problems. It is inconvenient for users to fix parts, the drilling position cannot be adjusted, and the work efficiency is not high. Based on these problems, Chinese patent CN220387940U discloses a fixing fixture for drilling machines. By setting a control box to start the transmission adjustment component and the connection push component, the transmission push component cooperates with the connection push component to automatically push and adjust the bottom of the adjustment rod, which solves the problem that the existing drilling machines need to manually adjust the use height of the motor when in use. At the same time, since the drilling machine will press down on the workpiece to drill during processing, the user needs to continuously adjust the use height repeatedly. Manual adjustment is not only inconvenient, but also prone to unbalanced height adjustment on both sides during adjustment, resulting in defective products during tilting processing during use, thereby reducing the convenience of using the drilling machine and achieving the effect of automatic adjustment.

[0004] The device only has the function of adjusting the height of the motor and does not have a fixed fixture structure. Therefore, the device cannot fix the drilling parts, nor can it adjust the drilling position of the parts, which seriously affects the use effect of the drilling machine. Utility Model Content
