Description

Z-axis mixed track ram structure for gantry center

Technical Field

The utility model relates to a machining center technical field, in particular to longmen center is with Z axle mixed track ram structure.

Background

The ram of the gantry machining center mainly plays a role in protecting and fixing a main shaft, completes the movement work in the Z-axis direction, mainly bears the gravity of the main shaft and the gravity of a main shaft motor mounted on the outer side, and needs to be kept undeformed under long-time pressure, so the ram of the gantry machining center needs to have good rigidity and bending resistance and pressure resistance.

The ram is divided into two types of moving work and guiding, one type is a hard rail and the other type is a linear rail, a guide rail and a lathe bed of the hard rail are integrated casting parts, and the hard rail has large friction force, large inertia, insufficient accuracy, slow moving speed and good rigidity; the linear rail has the advantages of high moving speed, high accuracy, good stability, poor rigidity, certain advantages and disadvantages when being used independently, and incapability of meeting the existing production.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a longmen center is with mixed track ram structure of Z axle, the mode of ram is connected to the mixed rail through hard rail and line rail, make it have the rigidity of hard rail, the accuracy of its removal has been increased simultaneously, the internal stress release hole that the ram was equipped with is regular hexagon hole, and constitute a honeycomb between the internal stress release hole, so when guaranteeing the functionality of internal stress release, can be when not influencing ram bulk strength, very big reduction self weight, and this internal stress release hole can make the air play from the downthehole circulation and carry out radiating effect to spindle motor.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a longmen center is with mixed track ram structure of Z axle, this ram includes the pillow body, first hard rail position and the hard rail position of second have been seted up on the lateral wall of the pillow body, fixed welding has first line rail installation position on the both sides wall that the pillow body is adjacent with first hard rail position and the hard rail position of second, second line rail installation position, third line rail installation position and fourth line rail installation position, internal stress release hole has been seted up on the terminal surface that this pillow body was equipped with first line rail installation position and second line rail installation position, the both sides of this internal stress release hole UNICOM pillow body, this pillow body top fixed mounting has fixed connection board.

Furthermore, the first hard rail position and the second hard rail position are slide rail positions extending from the pillow body and integrated with the pillow body.

Further, the internal stress release holes are regular hexagonal through holes.

Further, a honeycomb structure is formed between the internal stress release holes.

Furthermore, a plurality of mounting grooves convenient to mount are fixedly formed in the opposite surface of the ram and the first hard rail position.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a ram is connected to mixed rail of hard rail and line rail's mode, make it have the rigidity of hard rail, the accuracy of its removal has been increased simultaneously, the internal stress release hole that the ram was equipped with is regular hexagon hole, and constitute a honeycomb between the internal stress release hole, so when guaranteeing the functionality of internal stress release, can be when not influencing ram bulk strength, very big reduction self weight, and this internal stress release hole can make the air play from the downthehole circulation and carry out radiating effect to spindle motor.
