Abstract
Provided is a rapid tool changing device of a numerical control milling machine. The rapid tool changing device of the numerical control milling machine is installed on a gearbox of the numerical control milling machine, and is composed of a high pressure air pump and a wire thread insert. The high pressure air pump is installed at the upper end of a handling shaft outside the gearbox, the wire thread insert is installed at the lower end of the high pressure air pump, and the wire thread insert rightly faces the upper end of the handling shaft. According to the technical scheme, when a tool is changed, as only as a switch of the high pressure air pump is started, high pressure air can push the wire thread insert to extend downward, and the wire thread insert is sleeved on a shaft head of the handling shaft, the wire thread insert rotates in an impact mode under the push of the air pressure air, and drives the handling shaft to rotate, threads of the shaft head push the tool to move downward when the handling shaft rotates, and the tool is enabled to come off a tool fixing sleeve. The rapid tool changing device of a numerical control milling machine is simple and rapid in the modes of changing and installation of the tool, and high in working efficiency.
Description
Technical field
The utility model belongs to the machining equipment technical field, relates to a kind of tool changing device that is installed on the CNC milling machine.
Background technology
In the prior art, a side is equipped with driving shaft in the gearbox of CNC milling machine, the driving shaft upper end is connected with motor, on the spindle nose of lower end drive pulley is installed, opposite side is equipped with tool driving shaft in gearbox, driven pulley is installed on the tool driving shaft, drive pulley is connected with belt with driven pulley, end in tool driving shaft is equipped with the cutter fixed cover, cutter sleeve is contained in the cutter fixed cover, the center of tool driving shaft is equipped with the cutter loading-unloading axle, and the upper end of loading and unloading axle is hexagon, stretches out outside the gearbox.
CNC milling machine is when work, employed cutter is packed in the cutter fixed cover, in fixed cover, the screw thread of cutter loading-unloading axle lower end spindle nose is screwed in the screw of cutter upper end, cutter is upwards extracted, locating slot on the cutter snaps in the alignment pin of cutter fixed cover, can be with cutter to rotate together when tool driving shaft is rotated.
When changing cutter, the workman will stand on the board, and the hexagon spindle nose that screws loading and unloading axle in gearbox upper end with the spanner of large size rotates, and cutter is deviate from from the cutter fixed cover.This tool changing mode is required great effort time-consuming, and operating efficiency is lower.
The utility model content
The utility model is in the prior art, CNC milling machine adopts manual mode to finish when changing cutter, has large, the ineffective problem of labour intensity, and a kind of CNC milling machine tool changing device is provided, this device is installed on the gearbox of CNC milling machine, is made of high-pressure pump and swivel nut; A side is equipped with driving shaft in gearbox, the driving shaft upper end is connected with motor, on the spindle nose of lower end drive pulley is installed, opposite side is equipped with tool driving shaft in gearbox, and driven pulley is installed on the tool driving shaft, drive pulley is connected with belt with driven pulley, end in tool driving shaft is equipped with the cutter fixed cover, and cutter sleeve is contained in the cutter fixed cover, and the center of tool driving shaft is equipped with the cutter loading-unloading axle, the upper end of loading and unloading axle is hexagon, stretches out outside the gearbox; The high-pressure pump of this device is installed in the upper end of the outer loading and unloading axle of gearbox, and the lower end of high-pressure pump is equipped with a swivel nut, and swivel nut is over against the upper end of loading and unloading axle.
Adopt technical solutions of the utility model, when changing cutter, only need start the high-pressure pump switch, gases at high pressure can promote swivel nut and stretch downwards, be enclosed within loading and unloading axle spindle nose, and swivel nut impact type under gases at high pressure promote is rotated, drive loading and unloading axle rotates, and the screw thread promotion cutter of spindle nose was descending when the loading and unloading axle rotated, and cutter is deviate from from the cutter fixed cover.When packing cutter into, reverse starting high-pressure pump switch, high-pressure pump promote to stretch and backward rotation under the swivel nut, and swivel nut promotes loading and unloading axle spindle nose and inserts in the screw of cutter upper end, and the loading and unloading axle rotates, cutter is tightened and on carry, cutter is fixed in the cutter fixed cover.
After adopting technical solutions of the utility model, the mode of replacement and installation cutter is easy to be quick again, and operating efficiency is higher.
