Description

Gantry machine tool line (sliding) rail slide restraint structure

The invention relates to the technical field of gantry machinery, in particular to a gantry machine line (slide) rail slide restraint structure.

The structure of the conventional gantry machine 1 is as shown in Figures 5 and 6, and generally includes a line rail (or a rail, a hard rail) 12, at least one slider 14 that is slidably disposed on the rail 12, and a set. The head mechanism 16 on the carriage 14 allows the head mechanism 16 to move axially along the track 12 through the carriage 14.

The structure of the conventional slide 14 is slightly "呈" shaped by a cross-sectional view, and the slide 14 is subjected to the top-down pressure brought by the head mechanism 16, and must also bear the head mechanism 16 A lateral reaction force formed by interaction with a workpiece (not shown). The above-mentioned force easily causes the two side walls 142, 144 of the symmetry of the slider 14 to be deformed, and the occurrence of this deformation necessarily increases the amount of vibration and the offset of the movement of the head mechanism 16 or the interaction with the workpiece, resulting in the overall gantry machine 1 Processing precision is reduced.

Under the conditions of today's precision machining, the above-mentioned vibration amount or offset, even if it is only 0.1mm deviation, will result in poor processing results. Therefore, how to further solve this lack of deformation, there is clearly a need for further improvement in the structure.

In view of the above problems and deficiencies of the prior art, it is an object of the present invention to provide a gantry implement line (slide) rail slide restraint structure.

According to the above object of the present invention, a gantry implement line (sliding) rail slide restraint structure is provided, the gantry implement having at least one line rail, at least one slide seated on the line rail, and a head disposed on the slide seat The mechanism; as for the restraining structure of the line (sliding) rail slide, the two left and right lock seats symmetrically disposed on both sides of the slide seat, and the plurality of corresponding left and right lock seats, one end and the top of the slide seat Force components. By the composition of the above-mentioned members, the deformation of the slider is restrained to ensure the overall structure of the slider, and the deformation of the slider is prevented, resulting in a decrease in the precision of the overall gantry implement.

Hereinafter, the gantry machine of the present invention will be further described with reference to the related drawings. A line (sliding) rail slide restraint structure embodiment. In order to facilitate the understanding of the embodiments of the present invention, the same parts are denoted by the same reference numerals.

Referring to Figures 1 to 5, the gantry implement line (sliding) rail slide restraint structure of the present invention, the gantry implement 1 has at least one line rail 12, at least one slide seat 14 disposed on the line rail, and a A head mechanism 16 provided on the carriage 14. The line (sliding) rail slide restraint structure 200 includes two left and right lock seats 22, 24 symmetrically disposed on both sides of the slide 14, and a plurality of corresponding left and right lock seats 22, 24, and the top The elements 3 on both sides of the carriage 14 are forced.

The left and right lock seats 22 and 24 have a plurality of lock holes 222 and 242, and the lock member 26 is inserted into the corresponding lock holes 222 and 242 to fix the left and right lock seats 22 and 24 to the head mechanism 16 . Preset. In practice, each of the keyholes 222, 242 is selected from a through hole or a screw hole.

The abutting elements 3 are respectively corresponding to the partial locking holes 222 and 242 of the left and right locking seats 22 and 24, and then the two sides of the sliding seat 14 are urged. The top member 3 has a threaded section 32 and a screw head 34 at each end. In implementation, the screw head 34 is selected from the group consisting of a hexagon socket and an outer hexagon, and the pressing member 3 can further screw a tightening nut 4 to ensure that the abutting member 3 forms an abutment with both sides of the slider 14 .

Therefore, the above is a preferred embodiment of the present invention, and the various mechanisms of the gantry machine line (sliding) rail slide restraint structure are introduced, and then the assembly mode and the use characteristics of the present invention are introduced as follows: First, left and right The locking seats 22 and 24 are locked by the locking component 26, and the two sides of the corresponding sliding seat 14 are fixed at the preset position of the head mechanism 16, and then the left and right are adjusted. The top of the right locking seat 22, 24 urges the component 3 so that one end of each of the abutting members 3 abuts against the side end of the sliding seat 14, so as to restrain the two sides of the sliding seat 14 respectively, so as to prevent the sliding seat 14 from being subjected to the head mechanism. The phenomenon of deformation during the process of the force of 16 ensures that the head mechanism 16 maintains overall stability when moving through the carriage 14.

The above description is only for the preferred embodiment of the present invention, and is intended to clarify the features of the present invention, and is not intended to limit the scope of the embodiments of the present invention. Changes that are well known to those skilled in the art are still within the scope of the invention.
