Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain;
Fig. 1 is the schematic elevational view of a kind of embodiment of the utility model.
Fig. 2 be in the embodiment shown in Figure 1 discharge opening feeler arm B to the band partial cutaway the structural representation view.
Fig. 3 be in the embodiment shown in Figure 1 A-A to cutaway view.
The specific embodiment
According to numerical control ring mould discharge opening bevel device shown in Figure 1; It is made up of a rocking arm drilling rod 2 and drill bit 6 organisation of workings, feeler arm 3 and expansion link 4 mechanisms, the processing platform 11 of ring nib 7 and the circuit control module 15 of operating mechanism and each motion driver element of device thereof etc.; Wherein the processing platform 11 and the operating mechanism thereof of the driving mechanism of rocking arm drilling rod 2 and drill bit 6 and ring nib 7 are the basis with the prior art, use through appropriate reconstruction.In Fig. 1; rocking arm drilling rod 2 is contained on the support column 1 that is fixed in base 13, the discharge opening feeler arm 3 of a ring mould 7 is installed in its lower end, and this feeler arm 3 adopts the frame mode of quill that mobilizable expansion link 4 is housed in its front portion; at the front end of expansion link 4 a kind of sensing probe moving up and down 5 is installed; in addition, and as another kind of embodiment, expansion link 4 can use pneumatic or hydraulic part driving.
When this processing unit (plant) positions at the discharge opening 8 to ring mould 7, go out before expansion link 4 and the probe 5, and drill bit 6 center lines of pop one's head in 5 center lines and rocking arm drilling rod 2 are same center line.In feeler arm shown in Figure 23 mechanisms; Be equipped with one in the feeler arm 3 and shrink wheel 16 and stay cord 17, an end of this stay cord 17 is connected in expansion link 4, and other end volume is had mercy in shrinking wheel 16; In both activity spaces of expansion link 4 and feeler arm 3, a compression spring 18 is arranged; Shrink wheel 16 and drive, through the effect of spring 18 and scrolling stay cord 17, realize stretching out and retracting motion of expansion link 4 respectively by a small type stepping motor.
In the ring mould discharge opening bevel device shown in Fig. 1, have slide rail 12 on the base 13 of processing platform 11, processing platform 11 is contained on the slide rail 12, and processing platform 11 uses one handle wheel translation mechanism 14 on slide rail 12, to move.The corner that a pair of ring mould 7 is installed on processing platform 11 tops rolls letter 9 and rolling stand 10, and corner cylinder 9 and transmission mechanism thereof are driven by stepper motor 19.This mechanism is in support ring mould 7; Also be used for making ring mould 7 after the location processing of accomplishing a discharge opening 8, to rotate an angle on request; With location and the processing of carrying out next discharge opening 8; Behind the discharge opening 8 completion location and processing that are distributed on 7 one circumferences of ring mould; Operate the handle wheel translation mechanism 14 on the processing platform 11 by the people, be moved horizontally to ring mould 7 on its next circumference, thereby feeler arm 3 and rocking arm drilling rod 2 can be positioned and process the discharge opening 8 on whole ring mould 7 each circumference one by one.
Above-mentioned motion moves horizontally with 14 operations of handle wheel translation mechanism except that processing platform 11; All adopt driving system of stepping motor to drive; For each motion of making processing unit (plant) and machining tool on request with parameter coordination of setting and operation accurately; In device, be provided with the circuit control module 15 of each driving mechanism, this circuit control module 15 control respectively by a MCU chip transmission mechanism, the expansion link 4 of rocking arm drilling rod 2 and drill bit 6 expanding-contracting action, sensing probe 5 move up and down and encircle the rotational angle of mould 7 on corner cylinder 9 etc.
By the numerical control ring mould discharge opening taper surface processing unit (plant) of the utility model that Fig. 1 showed, during its work, earlier by manually-operated handle wheel translation mechanism 14; Make arbitrary discharge opening 8 of a circumference of the ring mould 7 that places on the cylinder 9 align the sensing probe 5 of feeler arm 3 basically, sensing probe 5 is worked after the instruction of receiving circuit control system 15, and provides detection data and deviation thereof; Circuit control module 15 is according to detection data, and the driving mechanism of index drum 9 comes the centre deviation of adjustment discharge opening 8 and probe 5 with the corner of regulating ring mould 7; After discharge opening 8 aligned with probe 5 central gauge, the driving mechanism that circuit control module 15 promptly starts expansion link 4 made expansion link 4 retractions, and circuit control module 15 starts drill bit 6 driving mechanisms of rocking arm drilling rod 2 by the machined parameters of setting simultaneously; Completion is to the bevel of discharge opening 8; After processing, circuit control module 15 is lifted drill bit 6, and the brake component of relieving expansion link 4 extend out to sensing probe 5 and the same position of center line in drill bit 6 places by expansion link 4 under the effect of spring 18; Meanwhile; Circuit control module 15 starts the stepper drive motors of cylinder 9 again, makes ring mould 7 rotate a corner by parameter request, lets the next discharge opening 8 that is on the circumference face toward sensing probe 5; Processing unit (plant) begins to repeat above-mentioned location procedure again, and so circulation.After the discharge opening on this circumference 8 all machined, manually-operated handle wheel translation mechanism 14 made sensing probe 5 face toward the discharge opening 8 on the next circumference and repeat above-mentioned process again, accomplishes up to ring mould 7 all discharge opening 8 bevel.
