Determined in recent years the T-shaped ram of beam gantry in the extensive use of part processing industry, current T-shaped ram is all to use external gearbox to carry out speed change to main shaft, the output shaft of gearbox is to be all connected with the main shaft of ram by belt, but in use, due to the cutting rigidity of T-shaped ram relatively a little less than, belt easily snaps, snapping of belt can cause external gearbox to damage, external gearbox cost is high, once and damage to be difficult to find at short notice the gearbox of replacement, bring great inconvenience to daily processing.
Summary of the invention
Technical problem to be solved in the utility model is to provide the T-shaped ram in integral type all-gear drive gantry, simple in structure, and gear is arranged in to ram inside, adopts all-gear drive, compact conformation, and maintenance rate is low.
The utility model solves the technical scheme that its technical problem adopts: provide integral type all-gear drive gantry T-shaped ram, comprise ram main body, motor and main shaft, described ram main body is vertically arranged on the slide rail of gantry, its inside, lower end is provided with main shaft, the upper end of described main shaft is connected with speed change output shaft by shaft coupling, the parallel intermediate propeller shaft that is provided with of one side of described speed change output shaft, ram main body one side of one side upper end of this intermediate propeller shaft is mounted with motor, the middle part of described speed change output shaft is provided with gear I, on the speed change output shaft of this gear I upper end, gear II is installed, the middle part of described intermediate propeller shaft is installed and is connected with geared sleeve by bearing, the outside, upper end of described geared sleeve is fixedly connected with gear III, this gear III is meshed with the driving gear that is arranged on motor output end, the upper end of described intermediate propeller shaft is connected with oil cylinder and moves up and down under the driving of oil cylinder.
Described gear III is meshed with gear II when oil cylinder is failure to actuate, and in the time of cylinder action, gear III and gear II are thrown off, and described gear I is meshed with geared sleeve.
Between described geared sleeve and gear III, by several coupled axle-pins, be connected.
The width of described driving gear is greater than the shift motion length of intermediate propeller shaft.
When oil cylinder moves, gear III and gear II are not meshed, and the rotation of motor drives main shaft to rotate at top gear by shaft coupling after driving gear and gear III, gear III and the transmission of gear II, realize the little moment of torsion output of high speed; When cylinder action promotes intermediate propeller shaft, move down, wait gear III and gear II and throw off, described gear I is meshed with geared sleeve, and now main shaft rotates at low or first gear, realizes low-speed big output, and compact conformation, realizes all-gear drive, reliability and durability.
beneficial effect
The utility model relates to the T-shaped ram in integral type all-gear drive gantry, simple in structure, used the integral structure that has installed speed-change and gearshift device in ram inside additional, and adopt all-gear drive, cancelled original expensive external gearbox and belt transmission, eliminated the dependence to external gearbox, structure is compacter, fault rate reduces greatly, and maintenance cost also reduces greatly.
Accompanying drawing explanation
Fig. 1 is that integral body of the present utility model is partly cutd open structure chart;
Fig. 2 is the structure chart of speed changing structure described in the utility model when top gear;
Fig. 3 is the structure chart of speed changing structure described in the utility model when low or first gear.
