The utility model content
The applicant adopts variable-frequency motor to drive for above-mentioned existing traction drive mechanism, four shortcomings such as the road wheel linear velocity is inconsistent, error is large, directive wheel is dumb, a kind of traction drive mechanism of rotary machine tool rational in infrastructure is provided, its good rigidly, Adjustment operation are conveniently, be convenient to safety and stability and drive the complete machine walking, thereby fully improved workpiece milling surface roughness and flatness.
The technical scheme that the utility model adopts is as follows:
A kind of traction drive mechanism of rotary machine tool, be installed in respectively the left and right sides of working head frame by mount pad, mount pad articulates by connecting bearing pin and wheel carrier, be provided with positive transport wheel and driven road wheel on the wheel carrier, the Connection Block of mount pad is fixed on the rotating disc, and the rotating disc bottom is articulated on the wheel carrier by inner ring, connection bearing pin; On the output shaft of driven by servomotor reduction box pinion is set, sheathed and be fixed with bull gear on positive transport wheel periphery step surface, the engagement by pinion and bull gear drives the positive transport wheel rotation.
The beneficial effects of the utility model are as follows:
The utility model changes the variable-frequency motor of traction drive mechanism into servomotor reduction box deceleration, and high-precision servomotor can guarantee effectively that the linear velocity of four road wheels of two cover traveling wheel mechanisms is consistent; And by the circumference driving, can not amplify the gash spacing error in the transmission mechanism, can guarantee well mobile accuracy; By the adjustable rotating dish can guarantee to be distributed in the working head both sides about two cover road wheels remain at the tangential direction of circumference, thereby effectively guarantee roughness and the flatness on traffic cycle processing work surface.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1 to Figure 3, traction drive described in the utility model mechanism is provided with two covers, be installed in respectively the left and right sides of working head frame 23 by mount pad 4, mount pad 4 articulates with wheel carrier 14 by connecting bearing pin 21, is provided with positive transport wheel 10 and driven road wheel 17 on the wheel carrier 14.The wheel shaft 13 of road wheel is bearing on the wheel carrier 14 by bearings at both ends, utilizes adjustment circle 16 axially to adjust, and utilizes the flat key ground-engaging wheel, and wheel shaft 13 1 ends are equipped with bearing air cover 11 and large cover 12, and the other end is equipped with bearing cap 15.
As shown in Figure 2, the connecting axle 19 of the utility model mount pad 4 is installed on the Connection Block 18, Connection Block 18 is installed on the rotating disc 20 by the outer-hexagonal bolt, rotating disc 20 bottoms are articulated on the wheel carrier 14 by inner ring 22, connection bearing pin 21, rotating disc 20 adopts bolt-locking after rotating and adjusting, therefore can guarantee to be distributed in the working head both sides about two cover road wheels remain at the tangential direction of circumference.
