9、ry table directly affect the benefit and the rise and fall of the turntable production enterprises. 1 The basic types of rotary table 1.1General turntable Rotary table is boring machine, drilling machine, milling machine and the slotting machine, and other important accessories, used for processing

10、and there is a requirement for dividing hole, slot and slope, turn the workbench when processing, can be processing arc surface and groove, etc. According to the structure is divided into different levels turntable general turntable, lie the turntable and universal turntable. (1) water flat turntabl

11、e: on the frustum of a cone with central hole workpiece positioning and clamping with T slots. Mesa engraved with 360 on the outer periphery of uniform scribed line. Mesa between base and a worm pole - worm gear pair, ratio of 90:1 or 120:1, to drive and dividing, worm out from base with dial and se

12、gment at the end of the handwheel. Turn the handwheel to drive mesa, and the mesa cylindrical week scale (in degrees) and subdivision dial readout rotation Angle. Dividing accuracy is commonly + 60 . Levels turntable worm out side can also be used coupling connected to machine transmission device, i

13、n order to realize the dynamic drive.(2) lie turntable, the base has two perpendicular installation base, make mesa can be level Also can be vertically.(3) the universal turret: mesa can be within the scope of 0 90 inclined at any Angle, make the workpiece at any Angle of space can be accurately adj

14、usted. 1.2 precision turntablePrecision turntable Used for processing or Angle measurement on precision machine tools. Common optical turntable, digital display turntable and super precision contrate gear plate of turntable.Optical rotary table: (1) on the spindle is equipped with glass or metal pre

15、cision dial, the optical system to subdivide scale, amplification, through the eyepiece or screen Angle value.(2) digital turntable: mounted on the turntable spindle precision circular grating or round inductosyn and display unit by the number of words the Angle value. The above two precision turnta

16、ble dividing precision up to + / - 1 .(3) the ultra-precision end tooth disc turntable: use a pair of precision of research on 1440, 720 or 360 tooth face tooth disc dividing positioning, the indexing accuracy up to + / - 0.01 , make a precise Angle measurement. 2 The design parameters and the worki

17、ng principle of rotary tableRotary table design parameters include: rotary table, table size, total table high degree, bearing table, feed speed, turning back to speed range, fast speed rotary speed, electric power, rotary table, dividing precision and measurement system, etc. This study is based on

18、 mechanism of shaanxi institute of technology laboratory of general rotary work Stage, through to tear open outfit, clear the turntable within the department of mechanical transmission mechanism, it is a mesa, pedestal, worm gear, worm, positioning3 Rotary table of research ideas and methodsRotary p

19、recision of the rotary table is a main technical bottlenecks, if technology and breakthrough in the continent before it has problems, design and manufacture of our country turntable will by manufacturing power to manufacturing power transformation of a major step forward.3.1 mechanical partsMainly t

20、he mesa rotary table with body contact structure design and optimization, generally adopts the sliding and rolling two ways; Second worm and worm wheel design and optimization. In short, the mechanical design involves the various parts of the turntable and parts of process structure, mechanical prop
