Lead screw horizontal installation supporting device and work process thereof

Abstract

The invention discloses a lead screw horizontal installation supporting device and a work process thereof. The lead screw horizontal installation supporting device comprises rollers, a bracket, a supporting plate, a guide rod, a piston rod, a piston and an oil cylinder body, wherein the oil cylinder body is located at the lower end of the lead screw horizontal installation supporting device; the piston capable of moving vertically is installed in the oil cylinder body and fixedly connected with the lower end of the piston rod; the piston rod is driven to move vertically through vertical movement of the piston; the upper end of the piston rod is fixedly connected with the supporting plate; the bracket is installed on the supporting plate and provided with the two opposite rollers used for supporting a horizontal lead screw, and one end of the supporting plate is fixedly connected with the guide rod. By means of the lead screw horizontal installation supporting device, the problems of large drooping deflection caused by self-gravity of the lead screw, poor parallelism and vibration caused in the movement process are solved, the effective stroke of the lead screw is not affected, and the problem that during machining, a workpiece is located in the center all the time, and a middle supporting device cannot work is solved. The lead screw horizontal installation supporting device and the work process thereof are simple in structure, safe and reliable.

Description

technical field [0001] The invention belongs to the field of machine tool manufacturing, and in particular relates to a support device for horizontal installation of screw rods and a working process thereof. Background technique [0002] When the CNC machine tool has a large stroke and moves in the horizontal direction of the screw drive, because the screw is too long, the self-weight of the screw and the installation process will cause a large sagging deflection, or the parallelism of the screw is not good. To solve this problem , Machine tool manufacturers usually use the pre-tensioning of the bearing at the end of the screw and the third point of support to reduce the sagging deflection of the screw and improve the rigidity and parallelism of the screw, but the effect is not obvious. When the table moves, that is, the screw rotates, the drooping of the screw and poor parallelism will cause the whole screw to vibrate, shorten the life of the screw and affect the machining ...
