Rolling and sliding compound guide track and manufacturing method thereof

Abstract

The invention discloses a rolling and sliding compound guide track and a manufacturing method thereof. The rolling and sliding compound guide track comprises a rolling and sliding positioning compound guide track and a rolling guide track, wherein the rolling and sliding positioning compound guide track comprises a first positioning block, a second positioning block, a first rolling body and a first positioning baffle plate, the first rolling body is sequentially fixedly connected with the second positioning block and the first positioning block, and the outward surface of the first positioning block is of a circular arc surface; and the rolling guide track comprises a third positioning block, an adjusting wedge block, a second rolling body and a second positioning baffle plate, wherein the second rolling body is sequentially fixedly connected with the adjusting wedge block and the third positioning block, and the outward surface of the third positioning block is of the circular arc surface. The rolling and sliding compound guide track provided by the invention can ensure the guide precision of motion of a ram and the bearing capacity of the guide track, simultaneously reduce the friction force between the ram and a transmission mechanism, and upgrade the sensitivity, the rigidity and the vibration resistance of the motion of the ram by combining the advantages of a rolling guide track and a sliding guide track; and furthermore, not only geometric tolerance requirement of a guide track mounting groove is ensured, but also processing efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of guide rails, in particular to a rolling-sliding composite guide rail and a manufacturing method thereof. Background technique [0002] With the rapid development of China's economy, especially the rapid development of high-speed railways, large-scale wind power equipment, domestic large aircraft projects, aerospace equipment, automobile manufacturing and construction machinery, there is a need for CNC floor milling and boring machining centers that can achieve high-speed and high-torque cutting demand is increasing.
