Technical field
The present invention is a kind of device and method testing cutter upset positioning precision in tool magazine, belongs to Digit Control Machine Tool field.
Background technology
Tool magazine and automatic tool changer in use, due to collision, positioned fastener loosen etc. accidental cause, make cutter overturn after positional precision change; And cutter, manipulator, relative-position error between main shaft three, directly affect accuracy and the reliability of lathe automatic tool changer; Therefore, be very necessary to the detection of positioning precision of cutter upset.
Because influence factor is numerous, and the influence degree of each factor cannot directly be determined again, therefore can only test out the positioning precision of cutter upset based on experiment.
In order to systematically study tool magazine and automatic tool changer in running, the change of the positioning precision of cutter upset, and grasp the rule of its precision change, need the apparatus and method of the test tool upset positioning precision of complete set, and also do not have relevant cutter to overturn the device of positioning precision at present.
Summary of the invention
The object of the invention is to design and a set ofly detect by laser displacement sensor A2, laser displacement sensor B4 the offset distance that cutter 3 overturns rear handle of a knife position and laser displacement sensor A2, laser displacement sensor B4, and utilize data collecting card to be transported in PC by the displacement signal of sensor, then the displacement signal of laser displacement sensor A2, laser displacement sensor B4 is processed and analyzed, obtain the upset positioning precision of cutter 3, in order to evaluate running precision and the performance of magazine 1 cutter turning device.Laser displacement sensor A2, laser displacement sensor B4 are the laser pickoffs that after running into testee by its own transmission laser, laser is reflected to self, thus obtain the distance between laser displacement sensor and testee.
To achieve these goals, this invention takes following technical scheme.Test a device for cutter upset positioning precision in tool magazine, it is characterized in that: comprise magazine 1 and automatic tool changer 6, laser displacement sensor A2, laser displacement sensor B4, cutter 3, mounting platform 7, switch board 8, virtual main shaft 5, cylinder 9, data collecting card and PC; Laser displacement sensor A2, laser displacement sensor B4 are fixed on the body of magazine 1 by sensor stand, and laser displacement sensor A2, laser displacement sensor B4 are in same level; When laser displacement sensor B4 installs, light of its injection should overturn the center of circle of the handle of a knife position after 90 ° through cutter 3 and parallel with magazine body; When laser displacement sensor A2 installs, light of its injection should become 150 ° of angles through the center of circle of cutter 3 handle of a knife position with the light that laser displacement sensor B4 penetrates, and cylinder 9 is equipped with two magnetic switch whether completes upset for detecting cutter.
Apply the method for described device, it is characterized in that: the target cutter number needs chosen by switch board 8, deliver to tool change position; And under the effect of cylinder 9, making cutter 3 complete upset, after upset, moment laser displacement sensor A2, laser displacement sensor B4 detect the offset distance distance values of cutter 3 handle of a knife position and the laser displacement sensor A2 be fixed on body, laser displacement sensor B4; The output signal of laser displacement sensor A2, laser displacement sensor B4 is collected on computer by data collecting card carries out Data Management Analysis.
Described laser displacement sensor A2, laser displacement sensor B4 are arranged on sensor stand, and by screw, sensor stand is fixed on the body of magazine, the accuracy of the offset distance of the cutter 3 handle of a knife position of actual measurement during to ensure to turn over cutter test and laser displacement sensor A2, laser displacement sensor B4; Sensor stand can finely tuned up and down perpendicular on the direction of horizontal plane, makes two laser displacement sensors in same level.Laser displacement sensor and support have certain adjustability when assembling, the ray intersection that sensor can be made to penetrate in the virtual handle of a knife center of circle as Fig. 3.The design of sensor stand ensures, laser displacement sensor A2, laser displacement sensor B4 are in same level, and the light that laser displacement sensor A2, laser displacement sensor B4 are penetrated is through the center of circle of virtual handle of a knife position.
Further, laser displacement sensor A2 is arranged on sensor stand, should become 30 ° of angles with tool magazine body, ensures that laser displacement sensor A2 and sensor stand effectively avoid the robot work scope of automatic tool changer 6.
Further, described mounting frame for sensor and laser displacement sensor A, the installed surface of laser displacement sensor B and the surface roughness of tool magazine body joint face are finish-milling-finish-milling or mill-mill.
The invention has the advantages that:
(1) the invention provides device and the detection method of a kind of tool magazine cutter upset location, cutter upset positioning precision when tool magazine runs can be detected dynamically, detection mode static than ever more adequately reflects the resetting error in cutter switching process, for manufacturer of producer provides the error parameter of cutter upset resetting.
(2) testing arrangement provided by the invention goes for the detection of different size dissimilar tool magazine cutter upset positioning precision, and not by the restriction of producer's magazine tool structure.
(3) what the present invention adopted is high-performance and high accuracy laser displacement sensor, easy for installation.Compared with current vortex and capacitance displacement sensor, this laser displacement sensor range is comparatively large, maximumly reaches 60mm, effectively can avoid the working range of manipulator; And resolution ratio is higher, measuring accuracy can reach 1.5um.
(4) method of testing provided by the invention is more novel.Because cutter 3 is standard components, the size for the cutter 3 handle of a knife position of different size is fixing, and machining accuracy is at ± 1 μm, so the handle of a knife size of each cutter 3 is consistent in same tool magazine.Therefore we by testing the distance of two points and the laser displacement sensor obtained in cutter 3 handle of a knife circle at every turn, can calculate the actual center of circle of turning over cutter position by converting.Detect the upset positioning precision of cutter 3 handle of a knife position by utilizing, it is feasible that indirect detection goes out the method that cutter 3 overturns positioning precision.
