Abstract
The utility model relates to a conjoined spindle encoder, which belongs to the technical field of automatic measuring devices. The conjoined spindle encoder is mainly characterized in that a spindle is rotatably mounted on a numeric control nose, a belt pulley is fixedly mounted on the spindle, a seat is fixedly mounted on the numeric control nose, an encoder housing is mounted on the seat, an oil seal is arranged on the encoder housing, a pulse counting board is fixedly mounted on the inner wall of the encoder housing, a code plate is fixedly mounted on the spindle within the encoder housing, the code plate matches with the pulse counting board, and a gap is reversed between the pulse counting board and the spindle. The conjoined spindle encoder is long in service life, because an encoder holder is arranged on the encoder, the encoder housing is mounted on the numeric control nose through the seat and the spindle is in no contact with the pulse counting board. Further, the conjoined spindle encoder has the advantages of simple, compact and reasonable structure, simplicity in production and assembly processes, high output signal precision, fine stability and reliability, and adjustable technical parameters.
Description
Technical field
The utility model relates to a kind of Contiuum type spindle encoder, belongs 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 by bringing synchronously, angle square board is fixed on the NCN vehicle body on the headstock, it is also higher that rotary encoder is finished cost of manufacture, and structure is numerous and complicated, bad, unstable easily.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and 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.
The technical scheme that provides according to the utility model, described Contiuum type spindle encoder, comprise main shaft, belt pulley, oil sealing, the 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 at the encoder outer casing inner wall, be on the main shaft of encoder enclosure and be installed with code-disc, 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 utility model is not owing to there is the encoder pedestal, and the encoder shell is installed on the numerical control headstock by pedestal, and main shaft and step-by-step counting plate are untouchable, so long service life; The utility model 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 schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, the utility model mainly is made 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, the main shaft 1 that is in encoder shell 4 inside afterwards is installed with code-disc 5 on 10～100mm, described code-disc 5 cooperates with step-by-step counting plate 7, and have the space between step-by-step counting plate 7 and the main shaft 1, promptly step-by-step counting plate 7 does not contact with main shaft 1.
Code-disc 5 is usually said grating in the utility model;
Step-by-step counting plate 7 is usually said pcb board in the utility model;
The utility model is not owing to there is the encoder pedestal, and encoder shell 4 is installed on the numerical control headstock 8 by pedestal 6, and main shaft 1 is untouchable with step-by-step counting plate 7, so the life-span is very permanent.
The utility model 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 can access the signal on the code-disc 5 and change into digital electric signal by step-by-step counting plate 7, being reflected in output device through simple processing of circuit exports with the square wave group, thereby finish by the signal and the controller of mechanical movement physical quantity (position, angle) to digital quantity (A.B.Z), the feedback that is used.
