The device of a kind of gantry building-block machine machining large workpiece
The utility model relates to a kind of gantry building-block machine machined servicing unit, the device of particularly a kind of gantry building-block machine machining large workpiece.
At present, machining industry is when machining large or ultra-large workpiece, and traditional method is that every processing one procedure is installed once; But when machining large workpiece and ultra-large workpiece, particularly on digital control combined machine tool, because frock is limit, both can not realize machining processes once being installed and finish whole combination process, lost the processed edge that equipment had, not only lose time, human and material resources, and when can not effectively utilize the device space and resource, be difficult to guarantee the crudy of product again.Traditional numerical control gantry machining aggregate machinery, maximum machining length are 20 meters, just must repeatedly process repeatedly above this range of work to be installed, and just can finish machined combination machining process.
Summary of the invention
The utility model just provides a kind of can once being installed and realizes the machining process of multiaspect, complex surface, and can effectively utilize the device space, mechanization degree height, has reduced labour intensity, shortens the process-cycle, improved the device of gantry building-block machine machining large workpiece of workpiece machining accuracy.
To achieve these goals, the utility model adopts following technical scheme: the utility model comprises base, crossbeam, column, workbench, bed body, motor, its structural feature is that the workbench left and right sides is respectively arranged with column, column is connected with crossbeam, and column drives crossbeam bed body along combination on motor-driven rack-and-pinion and vertically moves; Workbench is vertically moved along the base spherical guide that is arranged on the base by hydraulic oil cylinder driving, both formation relative motion in the same way.
As a kind of preferred version of the present utility model, the bed body of combination is formed by bed body head and the tail butt joint successively, locatees with wedge locating block, and connects with bolt.
As another kind of preferred version of the present utility model, the bed body of the rack-and-pinion of combination and combination is provided with accordingly.
The utility model of employing said structure has enlarged the range of work of gantry building-block machine, makes lathe of the present utility model not be subjected to the limitation of oil cylinder stroke, and processing length can reach 10-100 rice.
The beneficial effects of the utility model: (1) product quality height: once be installed because the utility model can be realized gantry building-block machine processing, finish the multiaspect processing technology; Eliminated the machining deviation that secondary is installed and produces, guaranteed product in the processing link process by the quality problems that are installed and cause often.
(2) production efficiency height: once be installed because the utility model can be realized gantry building-block machine processing, save the time that repeatedly is installed, reduced working strength of workers, shortened the process-cycle, and solved the problems such as difficult processing of large-scale workpiece, improved production efficiency widely.
(3) reduced production cost, effectively utilized the device space: because the utility model has been saved human and material resources and the time has greatly been reduced production cost, effectively utilized the usage space of equipment, created good economic benefits and social benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Wherein, 1 is that base, 2 is that oil cylinder, 3 is that base spherical guide, 4 is that workbench, 5 is that a bed body, 6 is that rack-and-pinion, 7 is that a body spherical guide, 8 is that column, 9 is crossbeam.
The specific embodiment
The utility model comprises the bed body 5 that is positioned at base 1 both sides, bed body 5 tops are column 8, be provided with a body spherical guide 7 and rack-and-pinion 6 between bed body 5 and the column 8, described column 8 tops are linked to each other by a crossbeam 9, the base spherical guide 3 of described base 1 is provided with workbench 4, and oil cylinder 2 is between base 1 and workbench 4.Column 8 drives crossbeam 9 and vertically moves along a bed body 5 that makes up on by motor-driven rack-and-pinion; Workbench 4 is driven by oil cylinder 2 and moves forward and backward along the base spherical guide 3 that is arranged on the base 1, and both form the relative motion of square crossing.
The bed body 5 of combination is formed by bed body 5 head and the tail butt joint successively, locatees with wedge locating block, and connects with high-strength bolt.The rack-and-pinion 6 of combination is provided with accordingly with the bed body 5 of combination.
Lathe of the present utility model workbench 4 when milling maintains static, and workbench 4 moves during grinding, and crossbeam 9 maintains static.When Workpiece length surpassed oil cylinder 2 strokes, crossbeam 9 dragged and maintains static after grinding machine head moves to the position of grinding, and workbench 4 moves once more and carries out grinding, can repeat repeatedly, so the utility model is not subjected to the limitation of oil cylinder 2 strokes, and processing length 10-100 rice.
Below in conjunction with description of drawings use of the present utility model: the bed body that will make up 5 is located with wedge locating block according to applying working condition, and links into an integrated entity with high-strength bolt; Be provided with the horizontal level that the special adjustable parallels is adjusted lathe bed below the bed body 5; Workbench 4 both sides are provided with column 8 and are connected with crossbeam 9, and column 8 drives by the rack-and-pinion 6 transmission feeding mechanisms that motor-driven drives, the butt joint of rack-and-pinion 6 sectionals; The bed body 5 of combination cooperates with the tooth bar of combination, and its butt joint length can reach 100 meters; In like manner, base 1 also can adopt the butt joint form, and workbench 4 is arranged on the base spherical guide 3 and moves forward and backward by driving oil cylinder 2 power; Condition with the utility model machine tooling large-scale workpiece.
Its operation principle is as follows: workpiece is placed on the workbench 4, and workbench 4 drives by oil cylinder 2, can move forward and backward along the base spherical guide 3 that is arranged on the base 1; The left and right sides of workbench 4 is respectively arranged with column 8, and column 8 drives connected crossbeam 9, moves in the rack-and-pinion 6 transmission feeding mechanisms that servomotor drives; When workpiece carried out the machined of a station, workbench 4 maintained static, and began the processing overall process of this station; Completion of processing workbench 4 moves, and when workpiece during in the original range of work, column 8 and crossbeam 9 maintain static; When Workpiece length surpassed the range of work of original equipment, the machined that at this moment connects crossbeam 8 these stations of drive of column 8 partly moved to the machined surface of workpiece, maintains static behind the calibrating position, and workbench 4 moves to assigned address once more, begins to process machined surface; This working procedure can be decided according to the machined surface of workpiece, and can repeat repeatedly.
Because the utility model is the digital control combined machine tool corollary apparatus, be applicable to the building-block machine of a plurality of control systems respectively and the use of a plurality of lathe combinations of control system.
