The utility model relates to a dual-direct-connection encoder detecting mechanism consisting of a rotating disc (1), a split magnetic grid encoder (2), an integral optical grating encoder (3) and a fixed bracket (4), wherein a magnetic grid drum of the split magnetic grid encoder (2) is fixed on the rotating disc (1) by screws, and a reading head part thereof is fixed on a fixed bracket (5); and a shaft of the integral round optical grating encoder (3) is connected with the rotating disc (1), and a shell thereof is fixed on the fixed bracket (5) by screws. The dual-direct-connection encoder detecting mechanism can solve the problem of measurement of the rotating speed and the scale angle of a large working platform of a machine tool in the prior art.

Description

A kind of two direct-connected encoder testing agency
Technical field
The utility model belongs to the testing agency field, particularly relates to a kind of two direct-connected encoder testing agency.
Background technology
Along with the development of domestic economy technology, the demand of machine industry is from simple type, popular to compoundization, automation, maximization transformation.At the market demand of compoundization and maximization, my company has developed 6 meters specifications and has possessed turnning and milling complex function large-scale vertical lathe.When lathe was in the turning state, digital control system need be monitored the rotating speed of workbench, and digital control system need be monitored the corner calibration of workbench during for the milling state.Because rotary table weighs 30 tons, workpiece is estimated at 50 tons, cause the overall load rotary inertia very big, drive the drive chain that requires to extend for satisfying, increase the reduction of speed ratio, main motor is longer to the driving-chain of turntable through reduction box, and driving error is bigger, for realizing closed-loop control, the installation of detecting element is thought the closer to operating part is unreasonable, is Given this needed to design a kind of testing agency.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of two direct-connected encoder testing agency, with the rotating speed that solves the big workbench of lathe in the prior art and the mensuration problem of sub-degree angle.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of two direct-connected encoder testing agency is provided, form by rotating disk, split type encoder I, split type encoder II, fixed support and support, the magnetic grid drum of split type encoder I is fixed on the rotating disk by ring flange and screw, and its read head I is fixed on the fixed support by support; Split type encoder II is fixed on the ring flange by pressing plate and screw, and its read head II is fixed on the fixed support.
Split type encoder I is the split type encoder ERM220/80 of Heidenhain company, and split type encoder II is the split type encoder A860-2150-T511 of FANUC company.
Beneficial effect
Rotating speed when the utility model can be finished the work the platform high speed rotating, and the detection of angle framing signal during calibration, working stability is reliable, has improved the competitive advantage of lathe.
Description of drawings
Fig. 1 is the utility model profile.
Wherein: 1-rotating disk, 2-read head I, 3-magnetic grid drum, 4-support, 5-ring flange, the split type encoder II of 6-read head II, 7-, 8-pressing plate, 9-fixed support.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, a kind of two direct-connected encoder testing agency, form by rotating disk 1, split type encoder I, split type encoder II 7, fixed support 9 and support 4, split type encoder I is the split type encoder ERM220/80 of Heidenhain company, and split type encoder II 7 is split type encoder A860-2150-T511 of FANUC company.The magnetic grid drum 3 of ERM220/80 is by ring flange 5 and utilize screw to be fixed on the rotating disk 1, its read head I 2 is fixed on the fixed support 9 by support 4, split type encoder II 7 is by pressing plate 8 and utilize screw to be fixed on the ring flange 5, its read head II 6 directly is fixed on the fixed support 9, two encoders have all been finished direct-connected with turntable (or rotating shaft), ERM220/80 surveys turntable (or rotating shaft) rotating speed, A860-2150-T511 measures turntable (or rotating shaft) corner calibration, use A860-2150-T511 to be used for the calibration location during milling, feed back rotating speed with ERM220/80 during turning, two encoders work alone respectively, and Each performs its own functions, bring out the best in each other.
Implementation step is as follows:
1. play table at the magnetic grid drum of outer, beating is not more than 0.04mm.
2. adjust magnetic grid read head and magnetic grid drum of outer gap 0.15mm.
3. adjusting whole circle stop position makes in the coaxial 0.1mm of grating axle and turning cylinder.
4. the acquisition testing signal requires signal steady and audible.

Claims (2)
