Abstract
The utility model provides a novel ram guideway suitable for a boring, milling and drilling press, which comprises a ram head and a guideway; one side end of the ram head is disposed between an upper rail and a lower rail of the guideway; the width of the lower rail is bigger than the width of the upper rail; and the outer side of the lower rail outruns the center of the ram head. Therefore, the rigidity and bearing capacity of the ram guideway are effectively improved. With strong resistance against disturbing moment and good stability of machining precision, the ram guideway is particularly suitable for large-allowance heavy cutting processes.
Description
Technical field
The utility model belongs to the Machining Technology field, specifically a kind ofly is applicable to boring, mills, the novel ram gib of drilling machine etc.
Background technology
At present, in boring, mill, in the drilling machine, cutter normally is installed on the ram head of ram gib, by the motion of ram head on guide rail, realizes the advance and retreat of cutter.Can existing ram gib and since its guide rail up and down rail be wide structure, thereby the rigidity of guide rail and bearing are relatively poor, anti-disturbing moment performance is low, the machining accuracy poor stability, chipping allowance is little, is not suitable for high-rate cutting.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of rational in infrastructure, rigidity and bearing is good, be fit to the novel ram gib of big surplus machining.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises ram head and guide rail, and a side of ram head places between the upper and lower rail of guide rail, the width of following rail greater than last rail width.
The outside of above-mentioned rail down surpasses the center of ram head.
The beneficial effects of the utility model are: owing to adopt the guide rail of up-narrow and down-wide structure, and the outside of following rail surpasses the center of ram head, thereby has improved its rigidity and bearing effectively, and anti-disturbing moment ability is strong, the machining accuracy good stability is particularly suitable for big surplus high-rate cutting processing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is that lower platen, 2 is that rail, 3 is that ram head, 4 is that top board, 5 is that upper rail, 6 is a guide rail down.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
The utility model mainly is made up of ram head 3, guide rail 6, top board 4 and lower platen 1.One side of ram head 3 is between the last rail 5 and following rail 2 of guide rail 6, and it carries out spacing by the top board 4 that links to each other with last rail 5 with the lower platen 1 that links to each other with following rail 2 respectively in two ends up and down.The width L1 of the following rail 2 of guide rail 6 is greater than the width L2 of last rail 5, and the outside of following rail 2 that is to say that above the center of ram head 3 the width L1 of following rail 2 is greater than the centre-to-centre spacing H of the horizontal direction of ram head 3.
Claims (2)
1, a kind of novel ram gib comprises ram head and guide rail, and a side of ram head places between the upper and lower rail of guide rail, it is characterized in that: the width of following rail greater than last rail width.
2, a kind of novel ram gib according to claim 1 is characterized in that: the outside of above-mentioned rail down surpasses the center of ram head.
