Abstract
The utility model relates to a separating type pulse coder for a numerical control machine spindle, which comprises a coder disc and a light emitting receiver. The separating type pulse coder is characterized in that the rotation speed signal transmitting coder disc is coaxially connected with the machine spindle, provided with a light transmitting notch and partially located in a grooved frame, and a light transmitter and a light receiver are respectively arranged on two opposite walls of the grooved frame. The separating type pulse coder has the advantages that the coder which transmits spindle rotation speed signals through the rotating coder disc, the light transmitter and the light receiver is simple in structure, convenient in installation and accurate and reliable in rotation speed signal acquisition, the rotating coder disc is not rigidly connected with the light transmitter and the light receiver so as to avoid abrasion, the service life of the coder is long, and a mechanical transmission component is omitted, thereby greatly reducing manufacturing cost of the pulse coder.
Description
Technical field
The utility model relates to a kind of encoder, particularly a kind of main shaft of numerical control machine tool separate type pulse coder.
Background technology
Digit Control Machine Tool is adding man-hour to some parts, needs the rotating speed of strict control main shaft and the feed speed of Z axle, to guarantee machining accuracy.In order exactly the speed of mainshaft to be fed back to control system, adopt pulse coder to realize the feedback of speed amount usually.Pulse coder is installed on the driven pulley, and the driving wheel drive driven pulley coaxial with main shaft rotates synchronously with main shaft, and pulse coder is delivered to machine tool control system with the tach signal of gathering by cable.Utilize the complex structure of mechanical transmission mechanism output speed signal, the cost height, installation accuracy requires high, and installation difficulty is big, the long-time use, the relaxation of deformation of belt can influence the degree of accuracy of signal output, causes the reduction of machine finish.
Summary of the invention
The purpose of this utility model be to provide a kind of information gathering accurately and reliably, main shaft of numerical control machine tool simple in structure separate type pulse coder.
Technical solution of the present utility model is: a kind of main shaft of numerical control machine tool separate type pulse coder, comprise code-disc, light transceiver, it is characterized in that tach signal sends code-disc and is connected with machine tool chief axis is coaxial, code-disc is provided with a printing opacity breach, code-disc partly is positioned at groove-shaped frame, is respectively equipped with optical transmitting set and optical receiver on the two relative walls of groove-shaped frame.
Characteristics of the present utility model are: the coder structure that sends spindle speed signal by rotation code-disc and light transceiver is simple, easy for installation, the tach signal collection accurately and reliably, rotary part and light transceiver are not rigidly connected, can not produce wearing and tearing, long service life is not established mechanical transmission component, reduces the cost of pulse coder greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, 2, the main shaft of numerical control machine tool code-disc 1 and 2 coaxial connections of machine tool chief axis of separate type pulse coder, code-disc is provided with a printing opacity breach 3.Adopting model is the flute profile integrated optoelectronic device 4 of IA51HR, its two relative wall is respectively optical transmitting set and optical receiver, integrated optoelectronic device 4 is fixed on the lathe, the installation site should be satisfied the part code-disc and is positioned at groove, and the code-disc that is positioned at groove separates the optical transmitting set and the optical receiver of integrated optoelectronic device.5 is spindle motor among the figure, and 6 is gearbox, and 7 is machine tool numerical control system.In lathe when work,, code-disc rotates with main shaft, and when code-disc printing opacity breach rotates in the groove, the light beam that optical transmitting set sends passes the code-disc breach and is radiated on the optical receiver, and optical receiver changes the light beam that receives into the 5V electric impulse signal and is sent to digital control system.Other position of code-disc enters in the groove, will shelter from light beam, does not have signal to send, so code-disc whenever rotates a circle, and only produces an electric impulse signal and is sent to digital control system.
