Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] A milling power head for a CNC gantry milling machine provided by the present invention, the power head includes a sliding seat 1, a screw rod and a spindle box 2 that moves up and down along the screw rod, one side of the sliding seat 1 is provided with a groove that runs through the upper and lower sides of the sliding seat 1 , the lower part of the spindle box 2 is placed in the groove, the top of the slide seat 1 is provided with a hydraulic balance device, and the top of the spindle box 2 is linked with the hydraulic balance device.

[0015] In order to reduce the bearing axial force of the screw rod, improve the running accuracy and service life of the screw rod, make the headstock 2 move up and down flexibly, and realize strong and heavy chipping, the above-mentioned hydraulic balance device includes a buffer seat 3 and two balance oil cylinders 4, two One end...

Abstract

The invention relates to a milling power head of a numerical-control planer type milling machine. The milling power head comprises a slide seat, a lead screw and a spindle box. The spindle box moves vertically along the lead screw, a groove which penetrates through the slide seat from top to bottom is arranged on one side of the slide seat, the lower portion of the spindle box is placed in the groove, a hydraulic balance device is disposed on the top of the slide seat, and the top of the spindle box is hinged with the hydraulic balance device. The milling power head is simple in structure and convenient to operate, the hydraulic balance device assists the spindle box to move vertically, axial force born by the lead screw is relieved, the traveling precision of the lead screw is improved, the service life of the lead screw is prolonged, and the spindle box can vertically move flexibly and is high in heavy cut capacity. Besides, ventilation openings are arranged on two sides and the top of a protecting cover of the spindle box, and circulation reflux of air inside the spindle box is strengthened, so that heat inside the spindle box can circulate to the external, a cooling effect is good, and high precision can be kept even if the milling power head is used for continuous heavy cut for a long time.

Description

technical field [0001] The invention relates to a CNC machine tool component, in particular to a milling power head of a CNC gantry milling machine. Background technique [0002] The traditional gantry milling machine has a heavy hammer and counterweight, and the headstock moves up and down along the screw rod. Since the screw rod needs to bear axial force, the up and down movement of the headstock is inflexible, and the processing ability of heavy cutting is poor, and the headstock cover is formed into a closed space. , the heat dissipation effect of the spindle box is not obvious, which increases the temperature of the spindle and affects the machining accuracy of the machine tool. Contents of the invention [0003] The purpose of the present invention is to provide a power head with flexible up and down movement, strong heavy cutting ability and good heat dissipation effect in order to solve the problems of inflexible headstock movement and poor heavy-duty cutting proce...
