Bridge type gantry dual-layer guide mechanism

Abstract

The invention provides a bridge type gantry dual-layer guide mechanism. The bridge type gantry dual-layer guide mechanism includes a portable frame and two bases; two ends of the portable frame are movably arranged on the two bases; the bridge type gantry dual-layer guide mechanism includes a base guide mechanism; the base guide mechanism includes a bottom frame; a drive motor is fixedly arranged in the two bases each; output shafts of the two drive motors are in transmission connection with a gear rack fixedly arranged on the bottom frame each so as to drive the bases to move on the bottom frame in the extension direction of the gear racks; linear rails are arranged on the bottom frame and parallel to the gear racks; and slide blocks matching the linear rails are arranged on the bottoms of the bases. The base guide mechanism is arranged on a conventional bridge type gantry, the bases can move, the travelling length of the bridge type gantry is increased, and the working efficiency and the processing precision is improved.

Description

technical field [0001] The invention belongs to the field of gantry machine tools, and in particular relates to a bridge-type gantry double-layer guiding mechanism. Background technique [0002] With the rapid development of high-speed, high-precision, and long-stroke machining application technologies, people have put forward higher requirements for the machining accuracy and stability of machine tools and the complexity of workpieces. refer to image 3 , the large-scale bridge-type gantry machining center mechanism currently on the market is mainly composed of machine head 1, sliding seat 2, gate bridge 3, base 4, workbench 5, etc., refer to Figure 4 , the head moves along the X-axis gate bridge during processing. In the application of long-stroke machining, the machining stroke is limited by the stroke size of the original machine tool design. When a longer machining size is required, it cannot directly meet the application. In the longer processing stroke requirements...

Problems solved by technology

In the application of long-stroke machining, the machining stroke is limited by the stroke size of the original machine tool design. When a longer machining size is required, it cannot directly meet the application.

In the longer processing stroke requirements, the test is the difficulty of machine tool design such as the stroke length of the base, the driving stroke, and the stroke of the measuring element, resulting in complex structure, high precision, high manufacturing cost and difficulty, and low flexibility in use.
