Clamping device with good firmness for drilling machine machining

Abstract

The invention discloses a clamping device with good firmness for drilling machine machining. The clamping device comprises a base, a support column is fixed to the top outer wall of the base through screws, and the top and bottom of the outer wall of one side of the support column are separately connected with a limiting wheel and a rotating wheel in a sleeved mode. A moving block sliding groove is formed in the outer wall of the top of the base, and the inner wall of the moving block sliding groove is slidably connected with a moving block. A threaded rod mounting hole is formed in the outerwall of one side of the base, and the inner wall of the threaded rod mounting hole is connected with a threaded rod in a sleeving mode. A working table is fixed to the top outer wall of the limiting wheel through screws, and a fixed clamping plate is fixed to one side of the top outer wall of the working table through screws. The distance between a sliding clamping plate and the fixed clamping plate and the distance between two sliding plates can be adjusted, a workpiece can be clamped and fixed from multi-directions, the improvement of the clamping firmness is facilitated, it is beneficial toimprove the operation convenience and the stability of the working table, and the possibility of workpiece movement during machining can be reduced.

Description

technical field [0001] The invention relates to the technical field of drilling machine clamping devices, in particular to a clamping device with good firmness for drilling machine processing. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes, blind holes, and replace special tools. , can be expanded, countersinked, reamed or tapped, etc. During the processing, the workpiece is fixed, the tool is moved, the center of the tool is aligned with the center of the hole, the tool is rotated, and it is fed along the direction of the spindle. The operation can be Manual or motorized. [0003] If the workpiece is not firmly clamped during the drilling process, it is easy ...

AI Technical Summary

Problems solved by technology

[0003] If the workpiece is not firmly clamped during the drilling process, it is easy to cause the workpiece to shift during the processing, affect the processing effect, and even cause the workpiece to be scrapped, which increases the processing cost. The movement of the workpiece may also cause the drill bit to deform or even break, which is likely to cause accidents
