Technical field
The utility model relates to a kind of transmission gap adjusting mechanism of gantry numerical control cutting machine, specifically is applied to vertically do back and forth movement mechanism in the Numerical control cutting equipment, belongs to the cutting equipment technical field.
Background technology
At present, the transmission gap adjusting mechanism that uses in the Numerical control cutting equipment is mounted in the frame middle part, transfers the space, crack little, and to frame processing request height, the cycle is longer.The limit error that adds man-hour is difficult to adjust, and easily makes the rack-and-pinion engagement bad, therefore occurs the phenomenon of gear wear easily in running, and causes frequent maintenance, corresponding raising manufacturing cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, thus provide a kind of simple in structure, easy to adjust, assembling is easy, operate steadily, reliable transmission gap adjusting mechanism of gantry numerical control cutting machine.
The technical scheme that provides according to the utility model, described transmission gap adjusting mechanism of gantry numerical control cutting machine, comprise frame, holder, copper sheathing, turning cylinder, mount pad, gear, tooth bar, bearing, decelerator, screw rod, spring, nut, first bolt and second bolt, described bearing is packed in the mount pad, locate by spacer between bearing, spacer compression axis bearing outer-ring, decelerator is fixing on mount pad, and gear is connected with the output shaft of decelerator, the holder copper sheathing of packing into, described mount pad is connected by turning cylinder with holder, holder is installed on the frame by second bolt, and screw rod screws in frame, the spring screw rod of packing into, be screwed into nut and compress gear, the wheel and rack engagement.
Described first bolt is used for the perpendicularity between adjusting gear and the tooth bar.
Compared with the prior art the utility model has the following advantages:
The utility model numerical control cutting machine transmission gap adjusting mechanism is simple in structure, easy to adjust, assembly space is big, easy to process to frame, can improve the rigidity of frame, and reduce the phenomenon that the expensive reduction gearbox output shaft of the eighteenth of the twenty ruptures, reduce the maintenance rate that reduction box is changed, thereby reduced manufacturing cost, improved product quality.
