Description

The toolroom machine head section mechanism

Technical field

The utility model relates to a kind of toolroom machine head, refer in particular to and a kind ofly drive screw rod that head slides and to the biasing of column headstock the head fuselage is stretched to establish to column, go into partially in the column with the nose heave heart of vectoring aircraft, with the toolroom machine head section mechanism of the stability that obtains cutting stroke.

Background technology

The general purpose tool machine is quite a lot of, and as vertical toolroom machine, horizontal tool machine or planer-type toolroom machine, feature of the present utility model can be applicable in the various tool machine, but the application in this measure gantry toolroom machine (to call toolroom machine in the following text) explains; The common simple mechanism signal as shown in Figure 1 of known tool machine mainly is provided with a platform 11 on a support 1, be provided with slide rail 12 therebetween, makes a platform 11 can do the X axis slippage; Bed platform 11 tops are provided with a column of type moulding 13, and column 13 is provided with a headstock 14, is provided with slide rail 15 therebetween, can make headstock 14 make Y-axis to slippage; But a headstock 14 is provided with the head 17 of mounting cutting spindle 16, is provided with slide rail 18 (seeing also Fig. 2) therebetween, can make head 17 be subjected to the driving of a screw rod 19 thereon and does the axial upper and lower slippage of Z.

Please consult Fig. 2, Fig. 3 simultaneously, this screw rod 19 has at conplane configuration relation with 14 liang of wood side-guides 18 of headstock, because main shaft 16 is when upper and lower displacement is cut shown in arrow Z among Fig. 3, the resistance of cutting forms reaction force relatively, and it all causes moment to a upright slide rail 18 and the screw rod 19 of establishing on the plane that coexist; 17 weight behind the configuration main shaft of head are also not light on the other hand, its center of gravity place is to the side force of plane formation shown in arrow F among Fig. 3 at two wood side-guides, 18 places, this side force not only makes load and the infringement of screw rod 19 under aforementioned moment loading increase the weight of, and easily causes mechanism to present labile state; When head 17 high-speed displacements, easily produce simultaneously vibrations, make cutting precision attenuating, tool wear and lower the life-span, and consume mechanical energy.

The specific embodiment

See also shown in Figure 4, it is to be embodiment to be implemented on the planer-type toolroom machine, but in fact be not limited to use merely in the planer-type toolroom machine, as vertical toolroom machine, horizontal tool machine or other toolroom machine like that can also equivalent way use the feature described in the utility model embodiment; Wherein, therefore omit other trifling member for ease of understanding the utility model feature;

Among the utility model embodiment, mainly on a support 2, be provided with saddle 21, be provided with slide rail 22 therebetween, make saddle 21 can do the X axis slippage; Saddle 21 is provided with a platform 3, is provided with slide rail 31 therebetween, makes a platform 3 can make Y-axis to slippage; Bed platform 3 tops are provided with a column of type moulding 4, and column 4 comprises the column 41 that is positioned at a platform 3 both sides and is positioned at the spreader 42 of a platform 3 tops, and is whole one-body molded by foundry goods; But the spreader 42 of column 4 is provided with the head 5 of mounting cutting spindle 51, is provided with slide rail 43 (seeing also Fig. 5) therebetween, can make to be subjected to the driving of a screw rod 6 on the head 5 and to do the axial upper and lower slippage of Z.

See also Fig. 5, column 4 is provided with one in top spreader 42 and is arranged with interval 421, and respectively is provided with linear rail chair 422 in interval 421 both sides; Carrying head 5 both sides be provided with cutting spindle 51 respectively is provided with rail bar 52 and is flush-mounted on the described linear rail chair 422; Linear rail chair 422 forms with rail bar 52 can be for the slide rail 43 of head 5 slippages; Fuselage 53 foundry goods of head 5 are arranged with interval 421 to described column 4 and stretch and establish, fuselage 53 is also connect by this screw rod 6 and is driven by it closely being arranged with interval 421 bottoms and column 3, the center of screw rod 6 be arranged with interval 421 liang of wood side-guides 43 not on same plane, and go into a side of plane that this slide rail 43 forms spreader 42 in the column 4 partially, and keep suitable distance; Even structurally can make cutting spindle 51 centers of head 5 and two wood side-guides 43 almost on same plane.

The utility model embodiment is owing to be arranged with interval 421 slide rails 43 not on same plane on the spreader 42 in the center of this screw rod 6 and the column 4, and go into an example of this plane spreader 42 in the column 4 partially, so can make whole head 5 foundry goods centers of gravity stretches and establishes in the interval 421 that is arranged with of spreader 42 in the column 4, even also whole head 5 centers of gravity are toward column 4 skews that have than higher rigidity and steadiness, make the reaction force of screw rod 6 when driving head 5 downward or upward and cut by main shaft 51, or the side force moment of head 5 weight generations own, be offset to the opposite side on the vertically-arranged plane, slide rail 43 place of relative cutting spindle 51 because of screw rod 6, cutting spindle 41 is dwindled to the distance on this plane, the moment of aforementioned reaction force or head 5 weight own is reduced, head 5 issuable side forces are reduced or eliminate, to obtain on simple shown in arrow G among Fig. 6, the stabilized driving state of bottom offset increases the more known person of cutting precision; And the cutting spindle 51 among the utility model embodiment is if be located at same vertically-arranged plane with two wood side-guides 43, the moment that reaction force was constituted when then cutting spindle 51 cut is more zero, not only reduce vibrations, reduce energy loss, reduce tool wear simultaneously, cutter life is increased, and increase head 5 high-speed displacements ability, improve the stability of machining and obtain higher precision.

Take a broad view of above-mentionedly, the utility model can make head 5 obtain more stable driving condition, and the more known person of cutting precision is increased.

Though the utility model discloses with specific embodiment; but it is not in order to limit the utility model; any those skilled in the art; the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present utility model and scope, having done; or, all should still belong to the category that this patent is contained according to equivalent variations and modification that the utility model scope of patent protection is done.
