Graph of system of machine tool transmission and motion are calculated

The transmission system graph of machine tool of graph of system of machine tool transmission is to state the machine tool moves entirely the sketch map that transmission concerns. It is more accurate than transmission principle graph, clearer, more comprehensive the drive that the ground reflected a machine tool concerns. With simple regulation in the graph the symbol represents all sorts of transmission element (the graph of system of machine tool transmission of our country stipulates symbolic detailed sees national level GB4460 -- 84 " symbol of diagram of mechanical cartography mechanical movement " reach GB138 -- 74 " mechanical cartography -- the formulary symbol in motor-driven sketch map " ) . The transmission system picture of the machine tool is in to be able to mirror machine tool appearance and each main part on the umbriferous face of mutual position, and as far as possible scale is inside the contour line of machine tool appearance. The each drive component in the graph is deliver according to motion early or late ordinal, in order to spread out what the formal picture of the graph comes out. This graph states transmission concerns only, do not represent the real measure of each drive component and dimensional position. The number of power of the lead of diameter of the tine number that makes clear gear and worm wheel normally in the graph, belt annulus, guide screw and head number, electromotor and revolution, transmission shaft. The number of transmission shaft, normally from athletic source (electromotor) begin, hand order by motion, ordinal with Roman numerals Ⅰ , Ⅱ , Ⅲ , Ⅳ ... express. Next graphs are one Taichun center lathe advocate transmission system graph. Lathe of 12 stage speed change advocate transmission system pursues 2.

Transmission line expression is facilitating specification and the transmission line that know a machine tool, digitlize transmission system graph normally, with transmission line expression (transmission structure style) the transmission line that will convey a machine tool. Pursue on lathe advocate transmission line expression is: 3.

Progression of main shaft revolution is narrated before computational basis advocate transmission line expression, knowable, when main shaft is turning, use all sorts of different combination of position of axial of gear of group of each slippage gear, main shaft can get 3 × class of 2 × 2=12 is turning rotate speed. Manage together, when electric machinery inverts main shaft can get 12 class to invert rotate speed. 4.

Computation of motion of athletic computation machine tool has two kinds of cases normally: (1) concerns data according to what transmission line expression offers, affirmatory and certain carry out athletic speed or displacement quantity; (2) basis carries out quantity of a wants athletic rate, displacement, or about carry out between need retentive motion concern, decide the drive of orgnaization of the displacement in corresponding drive catenary is compared, so that undertake,adjust.
