Abstract
The utility model discloses a work bench base of a gear grinding machine, which comprises a base body. A cylindrical cavity is vertically arranged at the centre of the base body, a torque motor is fixedly mounted inside the cavity, a rotor of the torque motor is connected with a work bench connecting seat, and a stator of the torque motor is connected with the base body. The gear grinding machine work bench base has reasonable design, simple structure, and the advantages of short transmission chains, 'zero' backlash, fine rigidity and the like, and the torque motor realizes closed loop control via a highly precise angle coder installed on the base body and retains correct positioning.
Description
Technical field
The utility model relates to a kind of machining equipment, is 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.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides that a kind of driving-chain is short, backlass is little, location and the high workbench base of gear grinding machine of control accuracy.
The technical solution of the utility model 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 utility model compared with prior art is following advantage:
The utility model 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 utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises a pedestal 1, and 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.
