Abstract
The utility model relates to a grating position detecting device of a machine tool spindle, comprising a machine tool sliding table plate, and a main shaft base A and a main shaft base B arranged on the machine tool sliding table plate, and the main shaft base A moves on the machine tool sliding table plate by rotating an adjusting screw rod; the grating position detecting device further comprises a grating contact sensor, a grating bar and a signal digital processing device. The grating contact sensor is fixed on the main shaft base A by a bracket, the grating bar is fixed on the sliding table plate, the grating contact sensor is connected with the input end of the signal digital processing device, and the output end of the signal digital processing device is connected with a grating bar display. The mechanical displacement of the main shaft base is converted into digital pulse, the displacement of the main shaft base is converted and calculated by the digital pulse, the position detecting precision of the main shaft base can reach micrometer level, thereby completely ensuring the precision of the relative positions of processing holes and producing the products which are in accordance with the quality requirements.
Description
Technical field:
The utility model relates to a kind of measuring technique, more specifically to a kind of machine tool chief axis stop position checkout gear.
Background technology:
In the machining of ring mould because the diameter difference of ring die worker part, different in size, for the processing that adapts to workpiece enlarges the range of work, when Machine Tool design, designed an adjusting device, be used to regulate distance between homonymy two machining spindles adapting to the ring mould of different length, because this adjusting device is a frame for movement, when regulating, can not react the distance of adjusting intuitively, bring many inconvenience to the operator.
The utility model content:
The purpose of this utility model is to provide a kind of machine tool chief axis stop position checkout gear at the prior art weak point.
The purpose of this utility model is to realize by following measure: a kind of machine tool chief axis stop position checkout gear, it contains machine tool sliding table seat board and spindle drum A, spindle drum B mounted thereto, spindle drum A moves on the machine tool sliding table seat board by the turn adjusting screw(rod), its special character is to also have: grating contact sensor, grating chi bar, the signal digital processor; Described grating contact sensor is fixed on the spindle drum A by support, and grating chi bar is fixed on the slide unit seat board, and grating contact sensor connects signal digital processor input, signal digital processor output termination grating chi bar display.
Compared with prior art, the machine tool chief axis stop position checkout gear that employing the utility model proposes, change the mechanical displacement of spindle drum into digit pulse, calculate the displacement of spindle drum by the digit pulse conversion, the position detection accuracy of spindle drum can reach micron order, can guarantee the positional precision of institute's machining hole fully, produce the product that conforms to quality requirements.
Description of drawings:
Fig. 1 is the utility model embodiment front view.
Fig. 2 is Fig. 1 embodiment side view.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1～Fig. 2 has provided the structural representation of the utility model embodiment.A kind of machine tool chief axis stop position checkout gear, it contains: machine tool sliding table seat board 4 and spindle drum A, spindle drum B mounted thereto, and spindle drum A moves on the machine tool sliding table seat board by turn adjusting screw(rod) 3, also has grating contact sensor 6, grating chi bar 5, the signal digital processor; Described grating contact sensor is fixed on the spindle drum A by support 7, and grating chi bar is fixed on the slide unit seat board, and grating contact sensor connects signal digital processor input, signal digital processor output termination grating chi bar display.During the utility model work, detect by the displacement between fixed grating and the mobile grating being enlarged into Moire fringe and moving by grating contact sensor, when grating relatively moves, Moire fringe will move along the groove direction, the light-sensitive element of indication on grating receives the irradiation of a light pulse with regard to electric pulse of corresponding output, by the number of counting electric pulse just can the surveyors' staff grating displacement.With signal digital processor DSP these data are handled after detecting signal by grating contact sensor, and shown the result through raster display.Described grating contact sensor, grating chi bar, signal digital processor are commercial matured product, can directly buy from market.
The foregoing description does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
