Abstract
The invention relates to the machinery manufacturing industry, in particular to a heavy-duty precision rotary table, which comprises an upper body of the table, a lower body of the table, a spindle, a bearing a, a big gear wheel, a pinion, a worm wheel shaft, a flange plate, a spacer bush, a bearing b and a worm shaft, wherein the upper body of the table is connected with the lower body of the table through the spindle; the spindle is supported by the bearing a; the big gear wheel is arranged on the spindle; the pinion is arranged on the worm wheel shaft and meshed with the big gear wheel at different positions; the worm wheel shaft is supported in the lower body of the table through the bearing b and is meshed with the worm shaft; the worm wheel shaft is arranged in the lower body of the table through the flange plate; and the spacer bush is arranged between the pinion and the worm wheel. The heavy-duty precision rotary table has the advantages that: a static pressure support is formed between the upper body and the lower body of the table, and is high in bearing capacity and high in supporting rigidity; double gear meshing is adopted, the back lash between gear pairs is eliminated, and the upper body of the table has high rotary precision.
Description
Technical field:
What the present invention relates to is machine industry, is specially a kind of heavy micro swivel.
Background technology:
At present, most of rotary table revolution drives by single worm and gear engagement, this device is owing to exist the back lash, cause the work table rotation precision to be difficult to guarantee, have influence on the machining accuracy of lathe, traditional rotary table is owing to be that face directly contacts with face between upper body and the lower body, and frictional resistance is big, table top is easy to wear, and considerable restraint is arranged on bearing capacity.
Summary of the invention:
The purpose of this invention is to provide a kind of heavy micro swivel, it can reduce the wearing and tearing between the rotary table surface of revolution, improves the rotary table supporting rigidity, and can simply effectively guarantee rotating accuracy.Technical solution of the present invention is: a kind of heavy micro swivel, specifically comprise the workbench upper body, the workbench lower body, mandrel, bearing a, gear wheel, pinion, worm-wheel shaft, ring flange, spacer, bearing b, worm shaft, the workbench upper body connects by mandrel with the workbench lower body, mandrel supports with bearing a, gear wheel is installed on the mandrel, pinion is installed on the worm-wheel shaft in different positions and gear wheel engagement, worm-wheel shaft is supported in the workbench lower body and with worm shaft by bearing b and meshes, ring flange is installed in worm-wheel shaft in the workbench lower body, and spacer is installed between the worm gear of pinion and worm-wheel shaft.Advantage of the present invention is as follows: form hydrostatic support between rotary table upper body and the lower body, and the load-bearing height, supporting rigidity is good, and it is little to wear and tear between the surface of revolution, adopts the engagement of bidentate wheel, has eliminated the back lash between the gear pair, workbench upper body rotating accuracy height.
Description of drawings:
The present invention is further described below in conjunction with drawings and embodiments
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
As shown in Figure 1, a kind of heavy micro swivel, specifically comprise: (1) workbench upper body, (2) workbench lower body, (3) mandrel, (4) bearing a, (5) gear wheel, (6) pinion, (7) worm-wheel shaft, (8) spacer, (9) ring flange, (10) bearing b, (11) worm shaft, workbench upper body (1) connects by mandrel (3) with workbench lower body (2), mandrel (3) is used bearing a(4) support, gear wheel (5) is installed on the mandrel (3), pinion (6) is installed in worm-wheel shaft (7) and goes up in different positions and gear wheel (5) engagement, worm-wheel shaft (7) is by bearing b(10) be supported in the workbench lower body (2) and and mesh with worm shaft (11), ring flange (9) is installed in worm-wheel shaft (7) in the workbench lower body (2), and spacer (8) is installed between the worm gear of pinion (6) and worm-wheel shaft (7).Concrete operation principle: workbench upper body (1) connects by mandrel (3) with workbench lower body (2), mandrel (3) is used bearing a(4) support, mandrel (3) provides the location for workbench upper body (1), workbench upper body (1) can be gone up around mandrel (3) rotation at workbench lower body (2), on the guide pass of workbench lower body (2), have oil storage tank and oil filler point, when rotary table starts, hydraulic oil enters in the oil storage tank by oilhole, between workbench upper body (1) and workbench lower body (2), form oil pressure, float on workbench lower body (2) upper table upper body (1), forms hydrostatic support.Gear wheel (5) is installed on the mandrel (3), two pinions (6) are installed in the workbench lower body (2), mesh in different positions with gear wheel (5), when two worm shafts of driven by motor (11) rotate, two worm-wheel shafts (7) rotate in the same way, and at this moment pinion (6) drives gear wheel (5) rotation, because two pinions (6) are in different positions and gear wheel (5) engagement, the rotating accuracy of rotary table has been improved in the gap that has produced when having eliminated transmission.
Claims (1)
