Abstract
The invention discloses a gantry beam lifting system. The gantry beam lifting system comprises a beam and two upright columns, and is characterized in that a limit switch and a locating oil cylinder component are arranged on the beam, the locating oil cylinder component comprises a locating oil cylinder and a locating pin arranged in the locating oil cylinder, a locating strip and a limit block component corresponding to the limit switch are arranged on one upright column, a plurality of locating grooves matched with the locating pin are arranged on the locating strip, the limit block component comprises a plurality of limit block groups arranged at intervals, each limit block group comprises at least two limit blocks determined according to binary coding, one lifter is arranged on each upright column, the beam is fixedly arranged on the two lifters, and the two lifters are connected with a reducing mechanism. The gantry beam lifting system has the advantages that the structure is simple and compact, the rigidity is good, the up-and-down movement of the beam can be accurately located, and the machining precision of a machine tool is improved favorably; compared with a traditional gantry beam lifting system driven by a servomotor, the gantry beam lifting system provided by the invention is low in cost and convenient in maintenance.
Description
Technical field
The present invention relates to a kind of jacking system, especially relate to a kind of gantry beam jacking system.
Background technology
Traditional gantry beam jacking system adopts the double cross flow servo motor to drive, and by the reduction box reduction of speed, drives the leading screw rotation, and leading screw supports and adopts fixedly prestretched structure of two ends, realizes the straight reciprocating motion of W axle, is furnished with hydraulic balance device in the crossbeam both sides simultaneously.Although this gantry beam jacking system is reliable, the crossbeam location is accurate not, and cost is higher simultaneously.
Summary of the invention
Technical problem to be solved by this invention is: for the deficiencies in the prior art, a kind of low cost is provided and can realizes the pinpoint gantry beam jacking system of crossbeam.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of gantry beam jacking system, comprise crossbeam and two root posts, be provided with limit switch and positional cylinder assembly on described crossbeam, described positional cylinder assembly comprises positional cylinder and is arranged on the alignment pin in described positional cylinder, be provided with positioning strip and the limited block component corresponding with described limit switch on a described column, be provided with a plurality of locating slots that match with described alignment pin on described positioning strip, described limited block component consists of many groups of spaced limited block groups, every group of described limited block group comprises at least two limited blocks determining according to binary coding, respectively be provided with a lift on two described columns, described crossbeam is fixed on two described lifts, two described lifts are connected with reducing gear.
Described slowing-down structure comprises interconnective reducing motor and shaft coupling, and the two ends of described shaft coupling respectively connect a described lift.
Two described lifts are self-locking elevator.Self-locking elevator also can self-locking after outage, improves the security of system.
Described positional cylinder assembly is connected with magnetic valve.The magnetic valve volume is little, and reliable in action is easy to maintenance, and cost is lower.
Compared with prior art, the invention has the advantages that: gantry beam jacking system of the present invention, its lift is connected with reducing gear, thus system can be used the less larger moment of motor transmission; This system noiselessness, without fluid leakage, environmental pollution is little, environmental; Simple in structure, compact, good rigidly, can locate moving up and down accurately of crossbeam, is conducive to improve the machining accuracy of lathe; Than the gantry beam jacking system of traditional employing driven by servomotor, cost is low, easy to maintenance.
