Abstract

The utility model mainly relates to a device of a compatible numerical control machine for inputting the amount of feed, in particular to a device for inputting the amount of feed by double handwheels of the compatible numerical control machine. The device comprises two handwheel devices (1) with scales, and the handwheels (11) of the handwheel devices (1) are fixed on two corresponding hand wheel shafts (12). The handwheel devices are arranged at the front part of an operation panel (5), and an impulsator (2) and a rotary encoder (3) are arranged on the hand wheel shafts (12). The handwheel devices (1) are connected with the output ends of the rotary encoder (3) and the impulsator (2) correspondingly, and the output ends of the rotary encoder (3) and the impulsator (2) are connected with a machine tool numerical control system. Through the combination of the displacement input method of the handwheels on a common machine and the numerical control machine, the operators can operate the numerical control machine as the common machine tool without the input of codes, thereby causing the numerical control machine to have the simplicity of the operation like a manually operated common machine tool.

Description

The general Campatible lathe of number is with the hands taken turns the device of the input amount of feeding

Technical field:

The utility model relates generally to a kind of device of counting the general Campatible lathe input amount of feeding, especially a kind ofly counts the device that general Campatible lathe is with the hands taken turns the input amount of feeding.

Background technology:

Digit Control Machine Tool is a kind of supermatic lathe, and part processing is moved automatically according to predetermined procedure fully.Need the code of being made up of literal, symbol, numeral according to the rules, the establishment part program follows a certain form.The action need of Digit Control Machine Tool is through professional training for this reason, and this brings many difficulty for the application and the development of Digit Control Machine Tool.

Existing Digit Control Machine Tool is vertically, the system of crossing feed is: coding input-computer-servomotor-ball-screw-sliding carriage system, sliding carriage system drive knife rest X to walk or Z to walking.

Conventional Digit Control Machine Tool is that adjustment or tool setting are provided with singlehanded wheel input unit, when lathe adjustment or tool setting need be changed the direction of feed motion of X-axis or Z axle, switch on the required direction of principal axis by change-over switch, have only X-axis, a Z axle pulse value of accepting the handwheel input among both, promptly lathe can only be realized motion in one dimension at one time at every turn.

Summary of the invention:

The purpose of this utility model be to avoid the deficiencies in the prior art part and provide a kind of count general Campatible lathe with the hands take turns the input amount of feeding device.Combining of its displacement input method by the handwheel on the machine tool and Digit Control Machine Tool makes the operator just can operate engine lathe operating numerical control lathe by picture, the input of need not encoding, thus make Digit Control Machine Tool have the operation simplification that common manual is operated lathe.

The purpose of this utility model can be by realizing by the following technical solutions: a kind ofly count the device that general Campatible lathe is with the hands taken turns the input amount of feeding, include two handwheel devices (1) of band scale, the handwheel (11) that also includes described handwheel devices (1) is fixedly mounted on corresponding two hand wheel shafts (12), handwheel devices (1) is located at the front portion of operation panel (5), and impulse generator (2) and rotary encoder (3) are located on the hand wheel shaft (12); The corresponding connection of input of handwheel devices (1) and rotary encoder (3) and impulse generator (2), the output and the machine tool numerical control system of rotary encoder (3) and impulse generator (2) link.

The general Campatible lathe of described number is with the hands taken turns the device of the input amount of feeding, and described hand wheel shaft (12) is gone up correspondence and is provided with damping unit (4).

Because the essence of handwheel input unit is pulse output, the device of both hands wheel input knife rest displacement therefore of the present utility model is an independently operating unit, when being applied to dissimilar lathes, can be positioned over any position of being convenient to operate of lathe as required.

The beneficial effects of the utility model are, the device that the general Campatible lathe of described number is with the hands taken turns the input amount of feeding has adopted the both hands wheel apparatus, and the operator need not coding, can realize not having the encoding operation Digit Control Machine Tool.It is simple in structure, and is reasonable in design.Both hands are taken turns each self-supporting X-axis, and Z axle transmission pulse does not need change-over switch, X-axis, both can accept the pulse of corresponding separately handwheel input, each self-driven X-axis of the pulse of being sent simultaneously the Z axle, the servomotor of Z axle, lathe are interior at one time can realize two-dimensional motion.Help operator's both hands to operate simultaneously, to realize need not coding, both hands are operated handwheel input knife rest displacement simultaneously, can realize not having the encoding operation Digit Control Machine Tool.

Description of drawings:

Fig. 1 looks schematic diagram for the master of the utility model embodiment;

Fig. 2 is the handwheel devices 1 main cross-sectional schematic of looking of the utility model embodiment;

Fig. 3 is the schematic diagram of the both hands wheel input amount of feeding of the utility model embodiment.

The specific embodiment:

Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:

Embodiment: see Fig. 1, Fig. 2, a kind of count general Campatible lathe with the hands take turns the input amount of feeding device, include two handwheel devices 1 of band scale, be characterized in that the handwheel 11 that also includes described handwheel devices 1 is fixedly mounted on two corresponding hand wheel shafts 12, handwheel devices 1 is located at the front portion of operation panel 5, and impulse generator 2 and rotary encoder 3 are located on the hand wheel shaft 12; The corresponding connection of input of handwheel devices 1 and rotary encoder 3 and impulse generator 2, the output and the machine tool numerical control system of rotary encoder 3 and impulse generator 2 link.Correspondence is provided with damping unit 4 on the hand wheel shaft 12.

As shown in Figure 3, two handwheels 11 are connected with impulse generator 2 correspondences respectively, impulse generator 2 drives servomotor 71 with X-axis respectively by digital control system 6 and links to each other with Z axle driving servomotor 72, X-axis drives servomotor 71 and links to each other with ball-screw 82 with ball-screw 81 respectively with Z axle driving servomotor 72, and ball-screw 81 links to each other with sliding carriage system 91 with sliding carriage system 91 respectively with ball-screw 82.

The handwheel that the general Campatible lathe of described number is with the hands taken turns the device of the input amount of feeding whenever shakes lattice, and impulse generator produces an electronic impulse, and each pulse is minimum to the amount of feeding in length and breadth to be 0.001mm.It is the actual amount of feeding that the minimum amount of feeding multiply by multiplying power.Electronic impulse and multiplying power amount are input to digital control system, and the servo unit that is input to X-axis or Z axle after pulse signal and the computing of multiplying power amount by digital control system drives X-axis, the servomotor of Z axle.Servomotor produces simultaneously and feeds back signal to digital control system, determines whether its feeding puts in place.Servomotor by ball-screw to the sliding carriage system, the sliding carriage system drive knife rest X to walking or Z to walking.
