The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

Referring to figs. 1 through shown in Figure 9; Present embodiment boring machine knife bar reinforced seat 1; Be used to be installed on the knife bar 2 effect of knife bar 2 being played support; Knife bar 2 is installed on the boring bar 3, and boring machine knife bar reinforced seat 1 comprises segmental support 11 and a plurality of fixed blocks 12 with screw hole, and segmental support 11 overlaps assembly units by the first half segmental supports 13 with the second half segmental supports 14 and constitutes; The back of a bow 131, the 141 upper edges back of a bow length direction of the first half segmental supports 13 and the second half segmental supports 14 is provided with a plurality of adjustment screw hole 132,142 at interval, and 132,142 places are fastenedly connected in the adjustment screw hole with the first half segmental supports 13 and the second half segmental supports 14 by trip bolt 4.Boring machine knife bar reinforced seat 1 is installed in 2 last times of knife bar; The axis direction of knife bar 2 is parallel with the length direction of segmental support 11; Its mounting means is: the bow arm end face 133,143 of the first half segmental supports 13 and the second half segmental supports 14 is provided with knife bar mounting groove 134,144; And bow arm end face 133,143 is provided with the screw fixed hole 136,146 that penetrates bow arm 135,145, and correspondence is provided with fixing hole on the fixed block 12, and trip bolt 5 is connected fixed block 12 with segmental support 11; During installation; Unscrew trip bolt 5, knife bar 2 bodies of rod that are installed on the boring bar 3 are placed and embedded in the knife bar mounting groove 134,144 along the length direction of segmental support 11, the trip bolt 5 of screwing then is installed in boring machine knife bar reinforced seat 1 on the knife bar 2; In the present embodiment on the knife bar 2 no boring cutter end 22 be fixedly connected with the second half segmental supports 14, be fixedly connected with the first half segmental supports 13 near the position that boring cutter end 23 is arranged; In the time of need regulating the bearing length of boring machine knife bar reinforced seat 1 according to the size of machined surface, only need to select the fixed position of trip bolt 5 to get final product.

For strengthening the support steadiness of present embodiment boring machine knife bar reinforced seat 1; On the inner surface of the back of a bow 131 of the first half segmental supports 13, be installed with brace summer 15; The bow arm end face 133,143 of brace summer end face 151 and the first half segmental supports 13, the second half segmental supports 14 maintains an equal level; And be provided with knife bar mounting groove 152 equally, the body of rod of knife bar 2 embeds in this knife bar mounting groove 152, and adopts screw fastening fixing by fixed block 12.So, segmental support 11 is by bow arm end face 143 places of bow arm end face 133 places of the first half segmental supports 13, the second half segmental supports 14, and 3 the fixed support knife bars 2 in brace summer end face 151 places, has strengthened support strength.

Based on technique scheme; Optional, for ease of 1 installation and removal of present embodiment boring machine knife bar reinforced seat, the height of the inner side edge of knife bar mounting groove 134,144,152 is lower than the height of its outer side edges; When this sentences boring machine knife bar reinforced seat 1 and is in place; Knife bar mounting groove 134,144,152 is inboard near a side of machined surface 6, and opposite side is the outside relatively, and the difference in height Δ h of outer side edges and inner side edge is 20mm in the present embodiment; Then when boring machine knife bar reinforced seat 1 was in place, knife bar inside part 21 exposed knife bar mounting groove 134,144,152.During dismounting boring machine knife bar reinforced seat 1, only need unscrew trip bolt 5, make knife bar 2 from knife bar mounting groove 134,144,152 since the opening position disengaging boring machine knife bar reinforced seat 1 that outer side edges and inner side edge exist difference in height to form get final product; During installation, unscrew trip bolt 5 and make knife bar 2 embed knife bar mounting groove 134,144,152 owing to opening position that outer side edges and inner side edge exist difference in height to form from the knife bar mounting groove 134,144,152, tighten trip bolt 5 then and get final product.

When according to the bearing length of the size adjustment boring machine knife bar reinforced seat 1 of machined surface,, be convenient to screw and fix for the central axis that makes the adjustment screw hole 132,142 on the first half segmental supports 13 and the second half segmental supports 14 centering all the time; The first half segmental supports back of a bow outer surface 137 is provided with slide rail 138 makes the back of a bow 131 be the T font; Correspondence is provided with chute 148 on the second half segmental supports back of a bow inner surface 147, is the U font, then during length adjustment; Slide in the chute 148 of slide rail 138 on the first half segmental supports 13 on the second half segmental supports 14; When sliding into appropriate length,, be fastenedly connected by trip bolt 4 with adjustment screw hole 132,142 center.

Too big so that knife bar 2 stretches out oversize its no boring cutter end 22 that makes and does not reach the knife bar mounting groove 144 on the second half segmental supports 14 when the machined surface area, and boring machine knife bar reinforced seat 1 also comprises knife bar length extension bar 7.During use; The head end of knife bar length extension bar 7 is pierced into boring bar 3 and is against no boring cutter end 22 places of knife bar 2; The terminal knife bar mounting groove 144 that embeds on the second half segmental supports 14; And fixing by fixed block 12 employing trip bolts 5, the no boring cutter end 22 of knife bar 2 is fastenedly connected boring bar 3 to strengthen installation strength and stability by bolt 8 simultaneously.

The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
