Abstract
The invention relates to a siamesed mainshaft encoder, belonging to the technical field of automatic measurement devices. The siamesed mainshaft encoder is mainly characterized in that: a mainshaft is rotatably arranged on a numerical control headstock; a belt pulley is fixedly arranged on the mainshaft; a seat body is fixedly arranged on the numerical control headstock; an encoder casing is fixedly arranged on the seat body; an oil seal is arranged on the encoder casing; a pulse counting plate is fixedly arranged on the inner wall of the encoder casing; a coded disk is fixedly arranged on the mainshaft inside the encoder casing; the coded disk is matched with the pulse counting plate; and a gap is reserved between the pulse counting plate and the mainshaft. According to the invention, because an encoder seat body is not arranged, the encoder casing is arranged on the numerical control headstock through a seat body, and the mainshaft is not in contact with the pulse counting plate, therefore the service life is long; and the siamesed mainshaft encoder has the advantages of simple, compact and reasonable structure, simple production and assembly process, high output signal precision, good stability and reliability and technological parameter adjustability.
Description
Technical field
The present invention relates to a kind of Contiuum type spindle encoder, belong to the automatic measurement mechanism technical field.
Background technology
The conventional rotary encoder of using; Mostly all NCN lathe system are by installing synchronizing wheel on the main shaft; Synchronizing wheel drives synchronizing shaft and shaft joint through bringing synchronously; Angle square board is fixed on the NCN vehicle body on the headstock, and it is also higher that rotary encoder is accomplished cost of manufacture, and structure is numerous and complicated, easy damage, instability.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of Contiuum type spindle encoder that assembly technology is simple, output signal accuracy is high and reliable and stable of producing is provided.
According to technical scheme provided by the invention, said Contiuum type spindle encoder comprises main shaft, belt pulley, oil sealing, encoder shell, pedestal and numerical control headstock; On the numerical control headstock, be rotatablely equipped with main shaft, on main shaft, be installed with belt pulley, on the numerical control headstock, be installed with pedestal; On pedestal, be installed with the encoder shell; On the encoder shell, be provided with described oil sealing, be installed with the step-by-step counting plate, be on the main shaft of encoder enclosure and be installed with code-disc at the encoder outer casing inner wall; Described code-disc cooperates with the step-by-step counting plate, and has the space between step-by-step counting plate and the main shaft.
The present invention is not owing to there is the encoder pedestal, and the encoder shell is installed on the numerical control headstock through pedestal, and main shaft and step-by-step counting plate are untouchable, so long service life; The present invention is simple in structure, compact, reasonable, and its circuit is simple, the production assembly technology is simple, output signal accuracy is high, reliability good, and technological parameter can be adjusted.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, the present invention mainly is made up of parts such as main shaft 1, belt pulley 2, oil sealing 3, encoder shell 4, code-disc 5, pedestal 6, step-by-step counting plate 7 and numerical control headstocks 8.
This Contiuum type spindle encoder; Comprise main shaft 1, belt pulley 2, oil sealing 3, encoder shell 4, pedestal 6 and numerical control headstock 8, on numerical control headstock 8, be rotatablely equipped with main shaft 1, on main shaft 1, be installed with belt pulley 2; On numerical control headstock 8, be installed with pedestal 6; On pedestal 6, be installed with encoder shell 4, on encoder shell 4, be provided with described oil sealing 3, be installed with step-by-step counting plate 7 at encoder shell 4 inwalls; Be in the last code-disc 5 that is installed with of main shaft 1 back 10～100mm of encoder shell 4 inside; Described code-disc 5 cooperates with step-by-step counting plate 7, and has the space between step-by-step counting plate 7 and the main shaft 1, and promptly step-by-step counting plate 7 does not contact with main shaft 1.
Code-disc 5 is usually said grating among the present invention;
Step-by-step counting plate 7 is usually said pcb board among the present invention;
Numerical control headstock 8 is usually said NCN headstock among the present invention.
The present invention is not owing to there is the encoder pedestal, and encoder shell 4 is installed on the numerical control headstock 8 through pedestal 6, and main shaft 1 is untouchable with step-by-step counting plate 7, so the life-span is very permanent.
The present invention is simple in structure, compact, reasonable, and its circuit is simple, the production assembly technology is simple, output signal accuracy is high, reliability good, and technological parameter can be adjusted; Code-disc 5 on the main shaft (being grating) rotates the back and can the signal on the code-disc 5 accessed and changes digital electric signal into through step-by-step counting plate 7; Being reflected in output device through simple processing of circuit exports with the square wave group; Thereby accomplish by the signal and the controller of mechanical movement physical quantity (position, angle) to digital quantity (A.B.Z), the feedback that is used.
