Abstract
The invention discloses a workbench base of a gear grinding machine, comprising a seat body, the center of which is vertically provided with a cylindrical cavity, the cavity is internally and fixedly provided with a torque motor, a rotor of the torque motor is connected with a workbench connecting seat, and a stator of the torque motor is connected with the seat body. The workbench base has the advantages of reasonable design, simple structure, short transmission chain, zero reverse gap, good rigidity and the like, and the torque motor realizes closed-loop control via a high-precision angle encoder which is arranged on the seat body, thus keeping accurate positioning.
Description
Technical field
The present invention relates to a kind of machining equipment, be specifically related to a kind of workbench base of gear grinding machine.
Background technology
Rotatablely moving of traditional gear grinding machine working platform generally is to adopt servomotor to drive the workbench rotation that is arranged on the Workbench base by worm gear, worm screw to finish.The gear grinding machine working platform swing mechanism of said structure is higher to the required precision of worm gear, worm screw, and wherein, worm screw is generally two helical pitch worm screws, needs the processing of high precision screw grinding machine; Worm gear also need be by special-purpose worm gear hob processing.So this gear grinding machine working platform swing mechanism manufacturing process complexity, early investment is big.And because mechanical clearance, its positioning accuracy is also lower, generally between 30～15 rads.Simultaneously because its positioning accuracy of continuous wearing and tearing of worm gear, worm gear pair also can be more and more lower.Also to increase anti-backlash mechanism, system complex.
Summary of the invention
The objective of the invention is the deficiency that exists at prior art, provide that a kind of driving-chain is short, backlass is little, location and the high workbench base of gear grinding machine of control accuracy.
Technical scheme of the present invention is: a kind of workbench base of gear grinding machine, comprise a pedestal, the pedestal center vertically is provided with cylindrical cavity, it is characterized in that: be set with torque motor in the described cavity, the rotor of described torque motor is connected with the workbench Connection Block, and the stator of torque motor is connected with pedestal.
The pedestal of described rotor below is provided with angular encoder.
Be provided with the right-angled intersection bearing between described pedestal and the workbench Connection Block.
The present invention compared with prior art is following advantage:
The present invention is reasonable in design, and is simple in structure, has characteristics such as driving-chain weak point, " zero " backlass and good rigidly, and torque motor is realized closed-loop control by the high accuracy angular encoder that is installed on the pedestal, keeps accurate in locating.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes a pedestal 1, pedestal 1 center vertically is provided with cylindrical cavity, is set with torque motor in the described cavity, and the rotor 2 of described torque motor is connected with workbench Connection Block 3, and the stator 4 of torque motor is connected with pedestal 1.
The pedestal 1 of described rotor 2 belows is provided with angular encoder 5.
Be provided with right-angled intersection bearing 6 between described pedestal 1 and the workbench Connection Block 3.
