Oil distribution device applicable to five-axis horizontal type machining center rotating table

Abstract

The invention provides an oil distribution device applicable to a five-axis horizontal type machining center rotating table. The oil distribution device comprises an external supporting part, a pivoting support bearing (11), a core shaft (1), a main shaft (2) and an oil distributor middle layer (10). The core shaft (1), the oil distributor middle layer (10) and the main shaft (2) are sequentiallyarranged from inside to outside. The core shaft (1) is connected with the main shaft (2). The main shaft (2) and the oil distributor middle layer (10) are provided with inner milling semi-circular oilgrooves (9) correspondingly. The pivoting support bearing (11) comprises a bearing inner ring and a bearing outer ring. The core shaft (1) and the main shaft (2) are connected with the bearing innerring. The oil distributor middle layer (10) and the bearing outer ring are fixed to the external supporting part. According to the oil distribution device, the coordination performance between the oildistribution device and other parts is effectively improved, by arranging a double-layer oil distribution ring, the slewing diameter of the whole rotating table is reduced, space is more compact, meanwhile, the number of fluid channels is increased, and the machining difficulty is reduced.

Description

technical field [0001] The invention relates to the field of oil distribution devices, in particular to an oil distribution device suitable for the turntable of a five-axis horizontal machining center. Background technique [0002] In recent years, the precision machine tool industry has developed rapidly. High precision and multiple degrees of freedom have become the mainstream development direction of the machine tool industry. Accuracy requirements, more need to follow the A, B axis turntable, so there is a higher requirement for the design of its oil circuit system. [0003] Research and development personnel in related fields have also developed new oil distribution devices, such as the oil distribution device disclosed in patent document CN207695640U, which includes a front connector installed on the front end of the main shaft and a rear connector installed on the rear end of the main shaft. And a connecting rod and several distribution pipes arranged in the inner ho...

Problems solved by technology

[0004] However, in view of the particularity of the turntable used for fixtures in the automotive industry, that is, more oil pipelines are needed to ensure the stability and positioning accuracy of the fixture, and at the same time, the height of the turntable should be reduced as much as possible to save the space occupied by the turntable. The above-mentioned existing technologies often cannot achieve the desired technical effect. ; At the same time, due to the small size of the fluid groove on the oil ring, the existing technical solutions can only be equipped with process holes in the radial direction of the workpiece, resulting in greatly weakened adaptability to other parts
