The utility model discloses further set up to: the depth of the first groove is 1/3 the thickness of the saddle.
By adopting the technical scheme, the integrity of the middle carriage guide rail and the saddle can be improved on the premise of ensuring the structural strength of the saddle, and meanwhile, the whole structural stability of the large carriage is improved by matching with the slide rail, so that the machining precision is improved.
The utility model discloses further set up to: the guide rail of the middle carriage is a double-rectangular guide rail.
By adopting the technical scheme, the rectangular guide rail has the characteristic of easy manufacture and adjustment, and the maintenance of the large carriage is facilitated while the processing stability is improved by matching with the triangular groove, so that the production cost is reduced.
To sum up, the beneficial effects of the utility model are that: the stability of the large carriage structure is improved through the integral arrangement of the large carriage structure; the triangular groove of the large carriage is matched with the rectangular middle carriage guide rail, so that the machining stability is improved, and meanwhile, the production cost is reduced.

Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 3.
The utility model provides a two triangle guide rail planker, including two slide rails 1, saddle 2, well planker guide rail 23, two slide rails 1 use 2 length direction central lines of saddle as the symmetry axis and set up in dull and stereotyped bottom bilateral symmetry, slide rail 1 bottom is equipped with triangle guide rail groove 11, 1 bottom of slide rail still welds transmission piece 4, it has lead screw groove 41 to mill on the transmission piece 4, 2 tops of saddle are equipped with first recess 21, be equipped with well planker guide rail 23 in the first recess 21, the transmission piece is located saddle bottom width direction's central line, triangle guide rail groove 11 is located slide rail 1 bottom that slide rail 1 is close to transmission piece one side, the width of triangle guide rail groove 11 is 1/3 of slide rail 1 width, slide rail 1 width is 2/5 of two slide rail intervals. Because two symmetrical triangular guide rail grooves 11 are adopted, the two guide rails are uniformly abraded when the large carriage slides on the guide rails, the relative position is unchanged after abrasion, the influence on the machining precision is small, and the machining precision is high. The middle carriage guide rail 23 is arranged in the first groove 21, the integrity of the middle carriage guide rail 23 and the saddle 2 can be improved, the influence of the connection of the middle carriage guide rail 23 and the saddle 2 on the stability during sliding is reduced, and therefore the machining precision is improved. Meanwhile, the integral gravity center of the large carriage is also reduced, and the stability is further improved. The width of the triangular guide rail groove 11 is 1/3 of the width of the slide rail 1, so that the width of the slide rail 1 ensures the stability of the triangular guide rail groove 11, and the reduction of the contact area between the saddle 2 and the large carriage guide rail caused by the undersize of the width of the slide rail 1 and the width of the triangular guide rail groove 11 is avoided, the contact pressure is increased, the abrasion is aggravated, and the service life is influenced.
