Description

Casing louvre processing unit (plant)
Technical field
The present invention relates to a kind of casing louvre processing unit (plant).
Background technology
When producing motor case, need to process louvre on casing, as shown in Figure 1 and Figure 2, at the opening of casing 7 It is provided with annular breach 704 on the end face of end, is provided with through hole 705 and a base in the center of the bottom surface of casing 7 703, casing 7 is additionally provided with the hole, location 702 of at least one bottom surface running through casing 7, the louvre 701 of required processing Being positioned on the perisporium of casing 7, louvre 701 has several and requires the center of all louvres 701 at grade, with The center of the louvre 701 that Shi Yaoqiu any two is adjacent is all equal with the angle of the vertical join line of the axis of casing 7.
When at present processing louvre on casing, typically using the bottom surface of the annular breach on the end face of the openend of casing as Locating surface, say, that the bottom surface of the annular breach on the end face of the openend of casing is against on the end face of a bulge loop, makes Casing is positioned, and then casing is carried out drilling operation.In the above-mentioned process to casing, locating surface only one so that machine Shell is fixed insecure, and casing easily glances off because of stress when boring, and the area of the bottom surface of annular breach is less, Bulge loop landing from annular breach is easily made because stress glances off, it will make that processes on casing to dissipate after casing is fixing Hot hole is out of position, it will make the center of several louvres the most at grade, it will make normally making of casing With.
Summary of the invention
The accurate machine in position of the louvre that the technical problem to be solved is to provide on the casing so that being processed Shell louvre processing unit (plant).
For solving above-mentioned technical problem, the casing louvre processing unit (plant) that the present invention provides, including:
The gripper shoe being vertically arranged;
It is arranged on the positioning seat on a surface of gripper shoe and central shaft;
Activity is nested with positioning disc on center shaft, and described positioning disc includes the first disk body, the second disk body and axially arranged Three disk bodies, the first disk body, the second disk body and the 3rd disk body are one-body molded, and the first disk body is positioned at positioning seat, and the first disk body is with fixed The first detent mechanism making positioning disc position, the 3rd dish it is provided with after often turning a fixed angle at positioning disc on the seat of position Body is positioned at outside positioning seat and for being nested with casing to be processed, the 3rd disk body is provided with for making Tong Bu with positioning disc turn of casing The second dynamic detent mechanism, activity that the outer face of the 3rd disk body is provided with is nested with on center shaft and for being nested with by casing The positioning sleeve offseted with the end face of base in casing time on 3rd disk body, the second disk body be positioned at the first disk body and the 3rd disk body it Between, a surface of the second disk body offsets with the end face of positioning seat;
Described louvre processing unit (plant) also includes:
Connection post on the end face of centrally disposed axle;
Be connected that male screw connects for after casing is nested with on the 3rd disk body by the locking on positioning disc of the casing axial locking Dish;
Be arranged on above positioning disc for the drill bit after casing is nested with on the 3rd disk body, casing punched;
Another surface configuration of the second described disk body have one axially extended for when casing is nested with on the 3rd disk body with casing The bulge loop that the bottom surface of the annular breach on end face offsets;
The first described detent mechanism includes the mounting seat being arranged on the periphery wall of positioning seat, is provided with one along positioning seat in mounting seat Radial direction extend and run through the alignment pin of perisporium of positioning seat, the end near one end of the first disk body of alignment pin is hemisphere Shape, alignment pin is equipped with a stage clip, and one end of stage clip is connected with alignment pin, and the other end of stage clip is remotely located with mounting seat One end of seat offsets, and the periphery wall of the first disk body is provided with several circumferences and is uniformly distributed and is all generally aligned in the same plane with alignment pin On hemispherical groove.
As preferably, what the second described detent mechanism included being arranged on the end face of the 3rd disk body radially extend for The locating dowel that hole, location on casing coordinates.
After using above structure, the present invention compared with prior art, has the advantage that
In the present invention, using the inwall of casing as the first locating surface, using the end face of the base of casing as the second locating surface, process casing Time, casing is nested with on the 3rd disk body, now, the end face of the 3rd disk body and the intersection of the circumferential wall of the 3rd disk body and casing Inwall offset, the end face of positioning sleeve offsets with the end face of the base of casing, and so, casing is just by the first locating surface and second Locating surface is positioned, and is then locked by casing by locking plate, then can be holed casing by drill bit, this Casing is positioned by two locating surfaces of bright employing so that casing location is firm, and with the inwall of casing as the first location Face so that the area of the first locating surface is bigger so that casing is not easy to glance off because of stress, to avoid machine when boring On shell, the louvre of processing is out of position so that the position of the louvre on casing is accurate, it is ensured that the casing after processing is just Often use.
In second preferred version of the present invention, using the bottom surface of the annular breach on the end face of casing as the 3rd locating surface, When being nested with on the 3rd disk body by casing, the end face of bulge loop offsets with the bottom surface of the annular breach on the end face of casing, so, and machine Shell is adding man-hour, is just positioned by three locating surfaces so that casing location is more firm.
In the 3rd preferred version of the present invention, alignment pin extends along the radial direction of positioning seat and the first disk body so that First disk body is exerted a force by alignment pin along the radial direction of the first disk body, positioning disc so can be avoided to produce axially displaced, can To avoid making the position of casing be moved, so because positioning disc produces axially displaced so that on casing, processing dissipates The position of hot hole is more accurate.
In the 4th preferred version of the present invention, make casing and positioning disc synchronous axial system by locating dowel, by machine When valve jacket is put on the 3rd disk body, by locating dowel through the hole, location on casing, thus make Tong Bu with positioning disc turn of casing Dynamic, the second detent mechanism simple in construction, use reliable.
