Table drilling machine with pull rod for adjusting belt tension

Abstract

The invention discloses a table drilling machine with a pull rod for adjusting belt tension. The table drilling machine comprises a limiting bracket, the pull rod for adjusting the belt tension, a machine body, a drilling fixture, a guide column and a base; a worktable is mounted on the surface of the base; the guide column is mounted above the base; the machine body is mounted above the guide column; a motor is mounted on the right side of the pull rod for adjusting the belt tension; a handle is mounted on the left side of the pull rod for adjusting the belt tension; a main shaft is mounted on the right side of the limiting bracket; a drill bit is mounted below the drilling fixture; and a power supply switch is mounted on the front surface of the machine body. The table drilling machine is compact in structural design, is provided with the pull rod for adjusting the belt tension on the surface of the machine body, can adjust the belt tension at any time through the pull rod for adjusting the belt tension, prevents reduction of the tension due to belt wear, and is provided with the limiting bracket below the handle for effectively guaranteeing the machining precision.

Description

technical field [0001] The invention relates to the technical field of bench-top drilling machines, in particular to a bench-top drilling machine with a pull rod for adjusting belt tension. Background technique [0002] The bench drill is referred to as a bench drill. It is a small hole processing machine tool that is small in size and easy to operate. It is usually installed on a special workbench. The bench drill can be placed on the workbench and the spindle is arranged vertically. The drilling machine and the workbench are placed on the column, and the spindle is arranged vertically. The radial arm drilling machine can rotate and lift around the column. Usually, the headstock can move horizontally on the rocker arm. The milling and drilling machine table can move vertically and horizontally, and the drilling axis is arranged vertically. Drilling machines capable of milling. Currently, the existing desktop drilling machines on the market have a simple structure. During us...

[0002] The bench drill is referred to as a bench drill. It is a small hole processing machine tool that is small in size and easy to operate. It is usually installed on a special workbench. The bench drill can be placed on the workbench and the spindle is arranged vertically. The drilling machine and the workbench are placed on the column, and the spindle is arranged vertically. The radial arm drilling machine can rotate and lift around the column. Usually, the headstock can move horizontally on the rocker arm. The milling and drilling machine table can move vertically and horizontally, and the drilling axis is arranged vertically. Drilling machines capable of milling. Currently, the existing desktop drilling machines on the market have a simple structure. During use, the belt will be worn due to the high-speed rotation of the driving wheel and the driven wheel, resulting in an increase in the diameter of the inner ring of the belt, which in turn affects the transmission force of the spindle. Cause quality accidents, serious wear and tear are likely to cause safety hazards
