Auxiliary supporting and moving device for machine tool machining super-long workpiece

Abstract

The invention provides an auxiliary supporting and moving device for a machine tool machining a super-long workpiece. The auxiliary supporting and moving device comprises two cross beams, a longitudinal beam and a height lifting mechanism, wherein a first transmission screw rod is arranged on the first cross beam, a hand wheel is fixed to one end of the first transmission screw rod, and the otherend of the first transmission screw rod is connected with a gear motor; the longitudinal beam is installed between the two cross beams in a sliding mode, a second transmission screw rod is arranged onthe longitudinal beam, a hand wheel is fixed to one end of the second transmission screw rod, and the other end of the second transmission screw rod is connected with a gear motor; and the height lifting mechanism is installed on the second transmission screw rod in a sliding mode, a lifting driving device is provided with a lifting screw and a connecting rod which are crossed and rotatably connected, one end of the lifting screw is fixedly connected with a crank, the other end of the lifting screw is connected with a gear motor, the two ends of the connecting rod are fixedly connected with ascissors-type connecting rod, and a table top capable of horizontally rotating is arranged at the top of the height lifting mechanism. A machine tool with a short stroke can be used for machining anultra-long workpiece, outsourcing machining does not needed, the machining period is shortened, the machining cost is reduced, and remarkable economic benefits are achieved.

Description

technical field [0001] The invention relates to mechanical processing, in particular to an auxiliary support and moving device for processing super-long workpieces by machine tools. Background technique [0002] When the machine tool is working, the length of the workpiece to be processed must match the stroke of the machine tool. If the workpiece exceeds the stroke of the machine tool too much, the workpiece will be deformed and unstable due to the lack of support at the tail end of the workpiece, and the machining accuracy of the workpiece cannot be guaranteed. In the prior art, there is a method of supporting the workpiece with a bracket with casters. The method is: the bracket with casters supports the tail end of the workpiece. When the machine tool drives the workpiece to move, the bracket is driven by the workpiece to follow the movement. This method is difficult to ensure that the moving track of the bracket is consistent with the guide rail of the machine tool Paral...

[0002] When the machine tool is working, the length of the workpiece to be processed must match the stroke of the machine tool. If the workpiece exceeds the stroke of the machine tool too much, the workpiece will be deformed and unstable due to the lack of support at the tail end of the workpiece, and the machining accuracy of the workpiece cannot be guaranteed.

In the prior art, there is a method of supporting the workpiece with a bracket with casters. The method is: the bracket with casters supports the tail end of the workpiece. When the machine tool drives the workpiece to move, the bracket is driven by the workpiece to follow the movement. This method is difficult to ensure that the moving track of the bracket is consistent with the guide rail of the machine tool Parallel, the guide rail of the machine tool is subjected to transverse shear force and longitudinal shear force in the cross-sectional direction, which will damage the guide rail of the machine tool and affect the accuracy of the machine tool

Therefore, when the length of the workpiece exceeds the stroke of the machine tool, it is necessary to find outsourcing processing, but it is difficult to find outsourcing for large-scale machine tools, which will easily affect the construction period, and the cost of outsourcing is huge
