Structure of bracket for long lead screw

Abstract

The invention relates to the structure of a bracket for a long lead screw. The invention is characterized in that a first cylinder end cover, a cylinder body and a second cylinder end cover are in fastening connection via screws, to form a cylinder body in which a piston rod is arranged; a transmitting cover is mounted at the top end of the piston rod, and the lower end thereof is connected with a guide rail via nuts; a first oil pipe joint is mounted on the first cylinder end cover, and the entire cylinder is located and mounted on a cylinder base via the steps on the second cylinder end cover; the cylinder base and a guide seat for the guide rail are in fastening connection to a cross beam via screws; the bracket is mounted on the guide rail via screws; a roller shaft is mounted in the through-hole of the bracket; and a roller is mounted on the roller shaft. The invention capable of providing continuous supporting force for a long-stroke lead screw has the advantages of simple, compact and reasonable structure, convenient installation and operation and obvious application effect, resists the bending deformation caused by the gravity of the long-stroke lead screw, guarantees the transmission accuracy of the long-stroke lead screw, and extends the applicable range of lead screws having various strokes.

Description

technical field [0001] The invention relates to a long screw bracket structure, which is especially suitable for use in large-scale numerical control equipment that needs to use a long-stroke screw rod to provide supporting force for a long-stroke screw rod, and belongs to the technical field of mechanical structures. Background technique [0002] With the rapid development of my country's machinery industry, especially the rapid development of large-scale equipment manufacturing industries such as aviation, aerospace, shipbuilding, wind power, and metallurgy, the requirements for the strength, precision and high productivity of large structural parts are also getting higher and higher. The demand for large-scale, high-efficiency CNC machining centers is even greater. As the first choice for large-scale parts processing, large-scale machining centers need to increase their machining strokes while ensuring the original machining accuracy. [0003] In the transmission of large...
