The utility model discloses following beneficial effect has: by adopting the scheme, the upright post, the cross beam and the sliding seat of the lathe are all in welded structures, the portal frame guide rail is in an I-shaped steel structure, the structure is simple, the manufacturing difficulty and the manufacturing cost are reduced, the operation is convenient, the safety and the environmental protection are realized, and the problems of difficult transportation, difficult processing and manufacturing, difficult installation and debugging and environmental pollution in the casting process of large castings are solved.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a left side view of the present invention.
In the figure, 1-guide rail, 2-portal frame, 3-beam, 4-beam slide seat, 5-ram and 6-dust removing device.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figures 1 and 2, the gantry movable tube plate chamfering lathe comprises a guide rail 1, wherein a gantry 2 is connected onto the guide rail 1, a cross beam 3 is arranged on the gantry 2, a cross beam sliding seat 4 is connected onto the cross beam 3, and a ram 5 is connected onto the cross beam sliding seat 4. The guide rail 1 is formed by welding three sections of I-shaped steel, the total length of the guide rail is 11100mm, the guide rail is connected with a foundation through foundation screws, the guide rail has enough rigidity, and the foundation screws are structurally in a form of one-pull and one-top, so that the installation and adjustment of the I-shaped steel guide rail are facilitated. The portal frame 2 comprises a left upright and a right upright, the uprights are formed by welding steel plates, the bottom of one upright is connected with a driving wheel, the bottom of the other upright is connected with a driven wheel, the driving wheel is connected with a driving motor through a belt, the driving wheel moves on a guide rail after being driven, the stroke is 10000mm, limit switches are arranged on supports on the inner side of the guide rail, the number of the limit switches is 4, 2 limit switches are arranged on the inner side of one upright, and signals are respectively acquired, limited and suddenly stopped; 2 are installed to the inboard of the stand of the other side, get the signal respectively: limiting and stopping suddenly.
The cross beam 3 is formed by welding steel plates, and is 7400mm long, 400mm high and 250mm thick. The upper surface and the front surface of the beam 3 are provided with linear guide rails for moving the beam, and the rear side is connected with a beam sliding seat 4 through a rack. The beam 3 is connected with the upright post of the portal frame 2 through a screw, and the connection rigidity is enough. The crossbeam slide 4 moves on the crossbeam 3 through the rack on the crossbeam, the slide stroke is 6500mm, install the ram 5 in the middle of the slide, the rear side installs the movable box, the movable box passes through the reduction gear, exchanges and eats the motor, links to each other with the rack. The left side of the upper part of the beam sliding seat 4 is provided with a dust suction device 6. A dust suction port of the dust suction device 6 is arranged at the front end of the ram 5, and dust and scrap iron are recycled into a dust suction box when the steel wire brush disc is used for machining a workpiece, and the dust suction box needs to be cleaned regularly.
The ram 5 is connected on the beam sliding seat 4, and can do vertical feeding movement in the sliding seat vertical guide rail and can also do transverse feeding movement along with the sliding seat. The front end of the ram is fixed with a steel wire brush disc. The ram is driven by a hydraulic oil cylinder, the stepless speed regulation is realized, when a workpiece is machined, a certain working pressure is formed on the surface of the workpiece through the adjustment of the hydraulic oil cylinder, and the steel wire brush disc is lifted up to form a certain gap with the surface of the workpiece through the reverse control of the oil cylinder in a non-machining state. The ram adopts an alternating current variable frequency motor to drive a main shaft to rotate, the motor is arranged at the top of the ram and is driven by a single gear, the two gears reduce the speed and then transmit power to two parallel transmission shafts, the rotating directions of the two parallel transmission shafts are opposite, the two parallel transmission shafts are both arranged in the ram, and the front end of each transmission shaft is provided with a steel wire brush disc. When the steel wire brush disc works, a certain pressure is applied to the surface of a workpiece, and the pressure is realized through a hydraulic oil cylinder. The ram is balanced and driven to move up and down, a hydraulic balance mechanism is adopted, hydraulic cylinders are mounted on two sides of the ram to unload the weight of the ram, and the movement precision and stability of the ram are guaranteed.
