Description
Technical field
The present invention relates to a kind of drag chain for three coordinate measuring machine, be specifically related to a kind of drag chain for super long type three coordinate measuring machine (stroke range reaches tens meters of magnitudes).
Background technology
The gentle number of lines of cable of three coordinate measuring machine and specification various, usually drag chain inner chamber is collected in, connector moves reciprocatingly with the shifting axle of three coordinate measuring machine, and another connector is fixed on line cell wall, its containing U-shaped axial plane perpendicular to surface level.The power that the kinematic train of three coordinate measuring machine is arranged is low, general 100 ~ 400W, but requires that running precision is high, registration, and servomechanism resistance is little, and change in resistance is little, and noise is low.Lengthen with three coordinate measuring machine shifting axle stroke, even there is interior R side contacts and produce friction in drag chain gravity sag, servomechanism resistance strengthens, and change in resistance is large, and noise is large, drag chain wearing and tearing aggravation, and measuring machine drives and is disturbed that uncertain factor is increased is even stuck.Strengthen drag chain wall thickness or adopt steel material drag chain to strengthen rigidity, rigidity increases limited, and drag chain increases the weight of, and drag chain is still sagging, and the DC servo motor of power limited drives with jitter phenomenon, and fluctuation of service is even stuck.The multiple symmetric pyramid wheel of external name family expenses holds up drag chain, and R side right-angle side in drag chain, contacts with taper cone pulley inclined-plane DISCRETE ELASTIC SUPPORTS, stressed unreasonable, drag chain runs up and down and horizontal direction play strengthens, and has interference to three coordinate measuring machine precision, and stochastic error software is difficult to revise.
The support oriented device of the drag chain that domestic drag chain manufacturer provides, half stroke only solving drag chain has support and guiding, does not establish support and guide piece, can only solve the servomechanism of the three coordinate measuring machine of several meters of ranges at another half stroke.
