At present, researchers' experimental research on the internal flow characteristics of the oil chamber of the turntable of high-end CNC machine tools is mostly based on the oil chamber with a stationary bearing surface, and the observation results are quite different from the actual working conditions, which cannot meet the needs of experimental research
[0003] In order to overcome the shortcomings of the static loading surface of the existing oil chamber experimental device, the present invention provides an oil chamber observation device whose bearing surface can move linearly. In the turntable, the inner diameter of the oil chamber is much smaller than the distance between the center of the oil chamber and the center of the bearing table, so the rotation of the bearing table can be simplified as the horizontal movement of the bearing surface of the oil chamber

Embodiment Construction
[0013] The oil chamber observation device will be further described in detail below in conjunction with the structural drawings.
[0014] figure 1 It is a schematic diagram of an oil cavity observation device with a movable bearing surface. The device consists of a support table 1, a fixed piece 2, a servo motor 3, a synchronous belt 4, a driving wheel 5, a fixed plate 6, a driven wheel 7, a transition shaft 8, and a circle Shaped side wall 9, boss 10, fixed clip 11, base 12, nut 13, stud 14 constitute.
[0015] After the experimental device is built, the specific implementation process is as follows: firstly, the servo motor 3 drives the driving wheel 5 to move through the transition shaft 8, and the movement of the driving wheel 5 drives the synchronous belt 4 to move. There is no contact between the synchronous belt 4 and the circular side wall 9 to form a gap, and the lifting of the support table 1 is realized by hand-tightening the nut 13, and the oil seal edge gap betwe...

The invention discloses an oil chamber observation device with a moveable bearing surface, and belongs to the technical field of a method of using an experimental device to observe a flow field in an oil chamber. The device comprises a supporting platform, a fixing piece, a servo motor, a synchronous belt, a driving wheel, a fixing plate, a driven wheel, a transition shaft, a round side wall, a boss, a fixing clip, a base, a nut, and a stud. The device meets an actual working condition of motion of an oil chamber bearing surface in a machine tool rotary table, and assembly is simple and operation is simple. Price of component parts of the device is low, and experiment cost is greatly reduced. When an application pump makes fluid enter the oil chamber in a constant flow manner, an adjustable gap is between an upper wall surface of the oil chamber and the synchronous belt, and an oil film can be formed. The servo motor drives a belt wheel to move, and the synchronous belt is used as a bearing surface and does horizontal linear motion.
