The utility model discloses a display system for feed amount of a shaft of a boring mill, which comprises a digital display device, a motor feedback pulse coder for producing primary pulse, a servo unit for producing PG (program guidance) frequency division output and setting PG frequency rate, a bus receiver converting a differential pulse signal into a single pulse signal, and a programmable controller receiving and counting pulses, wherein the output of the pulse coder is connected with the input of the servo unit, a digital output end of the servo unit is connected with an input end of the bus receiver, an output end of the bus receiver is connected with a data input end of the programmable controller, and an output end of the programmable controller is connected with a data input end of the display device. The display system solves the problem that the current boring mill displays feed amount for each minute by a voltage mode, and the display precision is poorer, and has the characteristic of high display precision.
Description
Technical field
The utility model relates to a kind of boring machine technical field, and particularly boring machine is in system that running shows the amount of feeding of boring machine axle.
Background technology
Boring machine is a kind of lathe that mainly with boring cutter the existing pre-manufactured hole of workpiece is carried out boring.Usually, boring cutter rotates to be motion of main shaft, and boring cutter or workpiece movement are feed motion.It is mainly used in the machining high-precision hole or one-time positioning is finished the fine finishining in a plurality of holes, can be engaged in the processing of other machined surfaces relevant with hole fine finishining in addition.Use different cutters and annex also can carry out drilling, milling, cutting, its machining accuracy and surface quality will be higher than drilling machine.Boring machine is the capital equipment of large-size box part processing.
Therefore common boring machine all adopts and changes feeding because by each feeding of main driven by motor, and promptly main shaft is whenever goed around, and how many millimeters corresponding axle walks, and carries out gear shift by gear change hand lever.Digit Control Machine Tool is then realized per minute feeding or revolution feeding according to instruction.
At present, TX6213AF is arranged on the market, and common boring machine such as TX6216 is owing to adopt day intrinsic safety river SGDM series AC servo driver to separate transmission with SGMGH series AC servomotor, feeding and given fast be to realize infinite variable speedly by regulator potentiometer, adopt multiturn potentiometer.The corresponding servomotor 0-1500rpm of adjustable range 0-12V.The feeding (is example with the X-axis) of corresponding lathe is 4-3000mm/min.Through test of many times, find to regulate with potentiometer, show the per minute amount of feeding with voltage system, display precision is relatively poor, can not satisfy user's needs of production.
The utility model content
The purpose of this utility model provides a kind of display system of utilizing numeric display unit to show the boring spindle amount of feeding.Show the per minute amount of feeding, the problem that display precision is relatively poor in order to overcome present boring machine with voltage system.Satisfy user's demand of practical production.
The utility model for realizing the technical scheme that its purpose adopts is:
A kind of display system of the boring machine axle amount of feeding, comprise numeric display unit, it is characterized in that: also comprise the motor feedback pulse encoder that produces initial pulse, produce the servo unit that the output of PG frequency division also can be set PG branch frequency, differential pulse signal is converted to the bus receiver of single pulse signal, the programmable controller of received pulse and counting, the output of described pulse coder is connected with the input of described servo unit, the digital output end of described servo unit links to each other with the input of described bus receiver, the data input pin of the described programmable controller of output termination of described bus receiver, the data input pin of the described display unit of output termination of described programmable controller.
Concrete, in the display system of above-mentioned a kind of boring machine axle amount of feeding: described bus receiver is the bus receiver that a kind of differential pulse signal with 5V converts the single pulse signal of 24V to.
Further, in the display system of above-mentioned a kind of boring machine axle amount of feeding: described display unit is a touch-screen.
Further, in the display system of above-mentioned a kind of boring machine axle amount of feeding: described programmable controller is communicated by letter by the realization of RS485 port with the data between the described touch-screen.
The beneficial effects of the utility model: because the AC servo driver parameter Pn201 that adopts can set PG branch frequency number, utilize the feedback pulse signal of motor, select suitable feedback pulse number, input PLC high-speed counter interface X0 is by the PLC internal arithmetic, can calculate this per minute amount of feeding more accurately, therefore, the display precision height has overcome present boring machine and has shown the per minute amount of feeding with voltage system, display precision is relatively poor, can not satisfy user's demand of practical production.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the display system circuit theory diagrams of the utility model embodiment boring machine axle amount of feeding.
Among the figure: 1, encoder, 2, servo unit, 3, bus receiver, 4, Programmable Logic Controller, 5, display unit.
The specific embodiment
AC servo driver parameter Pn201 owing to employing in the present embodiment can set PG branch frequency number, utilize the feedback pulse signal of motor, select suitable feedback pulse number, input PLC high-speed counter interface X0, by the PLC internal arithmetic, can calculate this per minute amount of feeding more accurately.
