Accompanying drawing explanation
Fig. 1 is the structural representation of processing unit (plant) of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1.
A kind of elongated hole inner groovy processing unit (plant), it comprises fixed mount 10, locating piece 4, outer tube 7, inner sleeve 6 and push rod 5, described locating piece 4 needs to process in the elongated hole of inner groovy for being inserted on workpiece, the shape preferably frustum structure of locating piece 4, to realize its self-centering in workpiece elongated hole, in addition, locating piece 4 also can be designed to the adjustable chuck structure of external diameter to adapt to needs and the centering of different-diameter endoporus, one end and the fixed mount 10 of outer tube 7 are fixedly linked, the other end and locating piece 4 are fixedly linked, inner sleeve 6 is sleeved in outer tube 7 rotationally, inner sleeve 6 stretches out outer tube 7 near one end of locating piece outer and be provided with and cut groove blade row 2, that cuts that groove blade row 2 is provided with the adjustable depth of cut cuts groove cutter 1, the other end of inner sleeve 6 is connected with its driving mechanism rotated of driving, described drive unit can be made up of drive motors and driven wheel, driven wheel is arranged on inner sleeve 6, driven wheel is by reduction gear box or be directly meshed with the output shaft of the drive motors with driving gear, drive motors directly or indirectly drives the revolution between driving gear crop rotation 0-360 degree, and then drive inner sleeve to do the revolution of equal angular, inner sleeve drives and cuts the corresponding revolution of groove cutter do, thus realizes the cutting processing that angle of circumference is the inner groovy of 0-360 degree.Described push rod 5 is sleeved in inner sleeve 6, it inserts near one end of locating piece to cut in groove blade row 2 and be provided with and cuts groove cutter 1 move radially thus realize cutting the inclined-plane that the groove cutter amount of feeding adjusts along cutting groove blade row 2 for driving, the other end of push rod 5 is connected with its pressure head 8 moved axially in inner sleeve of driving, pressure head 8 is connected with hydraulic system, installs cut in one end of groove blade row 2 back-moving spring 3 being also provided with and push rod 5 is resetted at inner sleeve 6; The pointer 11 being used to indicate rotational angle is installed at the top of described inner sleeve 6, is provided with angle index at outer tube 7 with pointer 11 corresponding position and the probe 9 that can detect the relative outer tube rotational angle of inner sleeve 6 is installed.As shown in Figure 1.Probe available position sensor or ccd video camera carry out the detection of rotational angle, to sample and control signal for electrical system provides corresponding.Relevant scale value, pointer installation etc. all can have been adopted routine techniques and realized.
Driven wheel is driven to rotate the angle of setting by drive motors when the present invention works, driving gear wheel belt is propped up inner sleeve 6 and is rotated corresponding angle, the angle of rotating depends on the angle of circumference of inner groovy in hole, if 360 degree, then inner sleeve 6 can connect revolution, if be less than 360 degree, inner sleeve must carry out back rotation in the angle of setting, often rotate the cutting once completing a depth of cut, now hydraulic system can drive push rod to move certain distance, push rod promotes to cut groove cutter and radially moves the distance that is equivalent to the depth of cut, relation between push rod displacement and the depth of cut can be determined according to mathematical computations, after process finishing, hydraulic system release, push rod gets back to original position under the effect of back-moving spring.The rotational angle of inner sleeve in rotation process 9 carries out detection return to control system in time by popping one's head in, and to ensure, the length of cutting groove meets the regulation of drawing.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
