Abstract
The utility model relates to a gantry automatic correction device for a numerically-controlled machine tool of a double-drive stepping motor. The gantry automatic correction device for the numerically-controlled machine tool of the double-drive stepping motor comprises a machine tool body and a gantry driven by a double-driven stepping motor, a first origin block and a second origin block which are oppositely arranged on the guide rails of the machine tool body are respectively arranged on two sides of the rear end of the machine tool body, and a first origin switch and a second origin switch which are arranged in an identical plane with the first origin block and the second origin block and are matched with the first origin block and the second origin block are respectively arranged on two stand columns on two sides of the gantry. The first origin switch and second origin switch are respectively connected with a controlling device through wires. The gantry automatic correction device for the numerically-controlled machine tool of the double-drive stepping motor has the advantages of being simple in structure, convenient to use, and capable of adjusting the positions of the gantry driven by the double-drive stepping motor automatically, precisely and fast, enabling the gantry to be reset precisely, guaranteeing the precision of processed articles, reducing the labor intensity of workers, and improving working efficiency.
Description
Technical field:
The utility model relates to a kind of gantry automatic correction device of the Digit Control Machine Tool for two Driving Stepping Motors.
Background technology:
Present two stepper motors drive numerical control gantry machine tool, owing to the stepper motor that drives gantry is lost the reason such as step in running, be easy to cause gantry to reset inaccurate, again because himself can't automatically detect and adjust, its object error that processes is large, low precision so cause.In order to remedy this problem, general by adjusting manually, but labor intensive so not only, and also slow, the low precision of regulating the speed, efficient are low.
Summary of the invention:
The utility model provides a kind of gantry automatic correction device of the Digit Control Machine Tool for two Driving Stepping Motors, it is simple in structure, easy to use, can be automatically, the two stepper motors of adjustment accurately and fast drive the position at gantry, make its parking position accuracy, guaranteed the precision of the object that processes, alleviated workman's labour intensity, improve operating efficiency, solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: it comprises lathe bed and two stepper motor driven gantry, be respectively equipped with relative the first initial point block and the second initial point block in position that is positioned on the bed ways in both sides, lathe bed rear end, the column in both sides, gantry is respectively equipped with the first origin switch and the second origin switch that is positioned at same level and matches with the first initial point block and the second initial point block respectively with the first initial point block and the second initial point block; The first origin switch links to each other with control device by wire respectively with the second origin switch.
The letter of the utility model structure, easy to use, the first origin switch is triggered the processing of the signal that the first initial point block, the second origin switch feed back to when triggering the second initial point block by control device, control the stroke of two stepper motors, the purpose that realize automatically, the two stepper motors of adjustment accurately and fast drives the position at gantry makes its parking position accuracy, guarantees the precision of the object that processes, alleviate workman's labour intensity, improved operating efficiency.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, lathe bed, 2, gantry, the 3, first origin switch, the 4, first initial point block, the 5, second origin switch, the 6, second initial point block.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
Shown in figure, the utility model comprises lathe bed 1 and two stepper motor driven gantry 2, be respectively equipped with relative the first initial point block 4 and the second initial point block 6 in position that is positioned on lathe bed 1 guide rail in both sides, lathe bed 1 rear end, the column of 2 both sides is respectively equipped with the first origin switch 3 and the second origin switch 5 that is positioned at same level and matches with the first initial point block 4 and the second initial point block 6 respectively with the first initial point block 4 and the second initial point block 6 at gantry.The first origin switch 3 links to each other with control device by wire respectively with the second origin switch 5.
Job step of the present utility model is as follows: after the lathe start, control device is controlled the action of two stepper motors, and under the driving of two stepper motors, gantry 2 is brought to assigned address, then begins to process object.After the end to be processed, control device is controlled 2 times resetting of zeros of two stepper motor band driven portals again, return the resetting of zero altogether in two steps: the first step, move zero instruction of returning that presets by control device, gantry 2 can be returned zero and carry out coarse positioning in any position, treat the first origin switch 3 and the first initial point block 4, after the second origin switch 5 and the second initial point block 6 trigger respectively, control device can be processed feedack, obtain a deviate B, can be when receiving between the two last that triggering signal of the first origin switch 3 and the first initial point block 4 or the second origin switch 5 and the second initial point block 6 with timed unit, control gantry 2 past rightabouts that reset move 100mm, simultaneously, relatively default a reference value A and the deviate B of detection obtain an adjusted value C to control device automatically; Second step is fine positioning, when the first origin switch 3 of fuselage one side and the first initial point block 4 trigger, close the burst transmissions of this side, keep motor power, stepper motor by the fuselage opposite side moves forward and backward, and eliminates adjusted value C, gets back to former a reference value A, return zero automatic calibration this moment and finish, Digit Control Machine Tool can carry out again process operation.When the adjusted value C that detects when setting adjusted value, exceed the self-adjusting limit of power of lathe itself this moment, can not carry out automatic calibration, need close after lathe manually adjusts, and carries out normal process again and operate.
