Four-corner drilling machine suitable for equilateral drilling treatment

Abstract

The invention belongs to the field of drilling machine equipment, and relates to a four-corner drilling machine suitable for equilateral drilling treatment. The four-corner drilling machine suitable for equilateral drilling treatment comprises a shell, wherein four support blocks are fixedly and symmetrically arranged at the lower end of the shell; a support plate is fixedly arranged at the left side of the shell; a manual lifting device is arranged on the support plate, and the manual lifting device is used for manually lifting the drilling equipment; and a manual adjusting drilling table device is fixedly arranged at the upper end of the shell. Four equidistant corners of a target material can be synchronously drilled or tapped, the number of synchronously drilled holes can be changed according to the number of installed drill bits, a hand-operated lifting device is more beneficial to control of an operator, drill bit damage caused by too fast downward movement is effectively prevented, the linear distance between opposite angles of two holes can be changed by controlling a small motor according to the actual needs, the four-corner drilling machine is suitable for plates of various sizes and distances, and the drilling position can be adjusted by swinging the manual adjusting drilling table device in multiple directions.

Description

technical field [0001] The invention belongs to the field of drilling equipment, in particular to a four-corner drilling machine suitable for equilateral drilling. Background technique [0002] As we all know, a 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 and blind holes. Special tools can be expanded, countersinked, reamed, or tapped. However, during hole processing, especially drilling, it is easy to have a long cutting entangled on the drill bit, which cannot be removed. When there is too much accumulation, it is easy to cause accidents. Threatening the safety of the operator, and when encountering a large number of repetitive drilling and tapping of multi-hole positions, the existing...

[0002] As we all know, a 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 and blind holes. Special tools can be expanded, countersinked, reamed, or tapped. However, during hole processing, especially drilling, it is easy to have a long cutting entangled on the drill bit, which cannot be removed. When there is too much accumulation, it is easy to cause accidents. Threatening the safety of the operator, and when encountering a large number of repetitive drilling and tapping of multi-hole positions, the existing machine tools can only process one hole by one hole, and the workpiece or the position of the drill bit needs to be continuously moved during processing. , the operation is inconvenient, which greatly affects the work efficiency
