Abstract
The utility model relates to a low-cost high-precision closed-loop control indexing rotary table. The rotary table comprises a rotary table pedestal (1), a bearing main shaft (2), a worm drive (3), a drive motor (4) and a gap adjusting mechanism (5). The rotary table pedestal (1) can be connected to a machine tool. The bearing main shaft (2) is installed in the middle of the rotary table pedestal (1) and is supported by a bearing. The worm drive (3) is installed at the bottom of the rotary table pedestal (1), and the drive motor (4) is installed on one side of the rotary table pedestal (1). A power input terminal of the worm drive (3) is connected to the drive motor (4). A gap of the worm drive (3) is adjusted by the gap adjusting mechanism (5). The rotary table is advantaged by strong bearing capability, low equipment costs, high control precision and a long motor life.
Description
Technical field
The utility model relates to a kind of revolution carrying turntable, particularly low-cost and high-precision closed-loop control index table.
Background technology
Conventionally machine tool rotary working table is realized turntable gapless calibration by servo drive motor, and the manufacture difficulty of this turntable is high, and manufacturing cost is also very high.
The adjustment of the worm couple of rotary table regulates by pad conventionally, needs repeated measurement gap and match grinding spacer thickness.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, requires to provide that a kind of bearing capacity is strong, equipment cost is low, control accuracy is high and the low-cost and high-precision closed-loop control index table of motor long service life according to ring mould working grading.
The purpose of this utility model is achieved through the following technical solutions: low-cost and high-precision closed-loop control index table, it comprises turntable seat, carrying main shaft, worm couple, drive motors and gap adjusting mechanism, turntable seat is connected with lathe, carrying main shaft is arranged on the middle part of turntable seat and by bearings, carrying main shaft can be connected with chuck, worm couple is arranged on turntable seat bottom, drive motors is arranged on a side of turntable seat, the power intake of worm couple is connected with drive motors, the clutch end of worm couple is connected with carrying main shaft, the gap of worm couple is regulated by gap adjusting mechanism.
Described worm couple is two helical pitch worm couples.
Described gap adjusting mechanism is screw-type gap adjusting mechanism.
The utlity model has following advantage:
1, meet ring mould lathe to the requirement condition of turntable bearing capacity under, vertical bearing capacity reaches 500 kilograms, bearing capacity is large, has greatly lowered cost simultaneously.
2, drive motors and worm shaft direct connection, then drive main shaft to rotate by worm couple, cancelled gear transmission chain, by shortening driving-chain, improved mechanical precision, also reduced cost and manufacture difficulty simultaneously.The gap of worm couple is adjusted by external screw-thread and is regulated without match grinding spacer thickness repeatedly, efficient and convenient.
3, the stepper motor that adopts resistance to severe mist of oil environment, stepper motor is strong to the patience of cutting oil, has improved the service life of motor, auxiliary realize closed-loop control by electric simultaneously, has overcome the shortcoming of the low and easy step-out of stepper motor precision.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
