Abstract
The utility model provides an automatic control device for constant-linear-speed operation of a grinding wheel of a plain grinding machine. The purpose is to solve the technical problems that in the prior art, according to the plain grinding machine, the outer circle of the grinding wheel is abraded to cause decrease of the linear speed of the grinding wheel, so that size precision and surface roughness of a machined part are lowered. The automatic control device comprises an infrared displacement detector, a frequency converter and a grinding wheel spindle motor. An emitting/receiving device of the infrared displacement detector is arranged on the outer side of a protective cover of the grinding wheel of the plain grinding machine, transmits a window arranged on the protective cover of the grinding wheel to emit infrared rays to the outer circle of the grinding wheel or receive the infrared rays, and emits simulation currents to the frequency converter. The frequency converter outputs corresponding frequency according to the simulation currents transmitted by the infrared displacement detector. The automatic control device has the advantages that automatic constant-speed control over the linear speed of the grinding wheel of the plain grinding machine can be achieved, manufacturing precision and surface roughness of the machined part are improved, the service life of the grinding wheel is prolonged, the structure is simple, control is sensible, and cost is low.
Description
Technical field
The utility model relates to the permanent linear speed control technology of a kind of general-purpose grinder emery wheel, specially refers to the permanent linear speed running of a kind of general-purpose grinder emery wheel automaton.
Background technology
In machining, adopt general-purpose grinder to grind and add man-hour component surface, the emery wheel using is after grinding a period of time, wearing and tearing because of grinding wheel cylindrical, cause the linear velocity of grinding-wheel grinder bevel to decline, the crudy of part to be processed is affected, and its dimensional accuracy and surface roughness all decrease.Obviously, prior art general-purpose grinder exists grinding wheel cylindrical wearing and tearing, causes emery wheel linear speed to decline, and makes the problems such as the dimensional accuracy of part to be processed and surface roughness all decrease.
Summary of the invention
The grinding wheel cylindrical wearing and tearing that exist for solving prior art general-purpose grinder, cause emery wheel linear speed to decline, make the problems such as the dimensional accuracy of part to be processed and surface roughness all decrease, the utility model proposes the permanent linear speed running of a kind of general-purpose grinder emery wheel auto-controller device.The permanent linear speed running of the utility model general-purpose grinder emery wheel auto-controller device comprises infrared displacement detector, frequency converter and grinding wheel spindle motor, and infrared displacement detector is electrically connected to frequency converter, and frequency converter is electrically connected to grinding wheel spindle motor; The emitting/receiving of infrared displacement detector is arranged on general-purpose grinder protective hood of grinding wheel outside, sees through the window being arranged on protective hood of grinding wheel and launches or receiving infrared-ray to grinding wheel cylindrical, and send analog current to frequency converter; The analog current that frequency converter transmits according to infrared displacement detector is exported corresponding frequency, and controls the rotating speed of grinding wheel spindle motor with this.
The useful technique effect of the permanent linear speed running of the utility model general-purpose grinder emery wheel auto-controller device is to realize the automatic constant speed of general-purpose grinder grinding speed to control, the accuracy of manufacture and the surface roughness of workpiece have been improved, extended emery wheel service life, and, simple in structure, control sensitive, cost is lower.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the permanent linear speed running of the utility model general-purpose grinder emery wheel auto-controller device.
Below in conjunction with the drawings and specific embodiments, the permanent linear speed running of the utility model general-purpose grinder emery wheel auto-controller device is further described.
The specific embodiment
Accompanying drawing 1 is the structural representation of the permanent linear speed running of the utility model general-purpose grinder emery wheel auto-controller device, as seen from the figure, the permanent linear speed running of the utility model general-purpose grinder emery wheel auto-controller device comprises infrared displacement detector, frequency converter and grinding wheel spindle motor, infrared displacement detector is electrically connected to frequency converter, and frequency converter is electrically connected to grinding wheel spindle motor; The emitting/receiving of infrared displacement detector is arranged on general-purpose grinder protective hood of grinding wheel outside, sees through the window being arranged on protective hood of grinding wheel and launches or receiving infrared-ray to grinding wheel cylindrical, and send analog current to frequency converter; The analog current that frequency converter transmits according to infrared displacement detector is exported corresponding frequency, and controls the rotating speed of grinding wheel spindle motor with this.The permanent linear speed running of the utility model general-purpose grinder emery wheel auto-controller device is combined infrared displacement detector and frequency converter, in real time the abrasion condition of grinder wheel is detected, and by frequency converter, automatically adjust the revolution of grinding wheel spindle motor, thereby the constant speed that realizes grinder wheel grinding face linear velocity is controlled.The excircle dimension that detects emery wheel when infrared displacement detector (is generally grinding wheel cylindrical size decreases while changing, need to improve speed of grinding wheel spindle, to guarantee the constant of wheel grinding upper thread speed), infrared displacement detector is exported analog current to frequency converter, frequency converter is exported corresponding frequency according to this analog current to spindle motor, automatically improve grinding machine spindle motor speed, thereby realize the permanent linear speed motion of emery wheel.
Obviously, the useful technique effect of the permanent linear speed running of the utility model general-purpose grinder emery wheel auto-controller device is to realize the automatic constant speed of general-purpose grinder grinding speed to control, the accuracy of manufacture and the surface roughness of workpiece have been improved, extended emery wheel service life, and, simple in structure, control sensitive, cost is lower.
