Fig. 2 is the enlarged drawing at Fig. 1 I place;
Fig. 3 is the enlarged drawing at Fig. 1 II place;
Fig. 4 is the vertical view of Fig. 1;
Fig. 5 is the scale sketch map of calibrated dial.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
The architectural feature and the specification requirement of disk cover class part:
(1) generally all have axis hole on the disk cover class part, will consider usually to make positioning reference during the design drill jig with axis hole, but because the variation in aperture, this just makes the setting element of drill jig can not make the sizing axle;
(2) generally all have the circumference uniform distribution hole on the disk cover class part, 3,4,6,8,12,16,24 five equilibriums are arranged usually, what have also has higher halving precision requirement;
(3) the disk cover class part that has has higher pitch-row dimension precision requirement and centre-to-centre spacing dimension precision requirement; What have also has certain position accuracy demand.
Therefore, disk cover class part Universal Jig should be able to accomplish that axial height is adjustable, pitch-row is adjustable when boring, and can calibration.
To shown in Figure 3, disk cover class part Universal adjustable drill jig mainly partly is made up of measuring unit 1, bushing plate 2, drill jig axle 3, index dial 4 and positioning disk 5 etc. like Fig. 1.Bushing plate is fixed on the drill jig axle through second nut 7, and the drill jig axle is provided with measuring unit, and bushing plate is provided with slippage drill bushing 9; Unclamp first nut 6 (being the nut of claims and specification utility model content part); Move the slippage drill bushing, in the slippage drill bushing, insert axle 8 again, just can pass through the distance L of vernier caliper measurement itself and measuring unit; Adjusting obtains the centre-to-centre spacing in processed hole; Tighten first nut this moment, fixes the position of drill bushing, promptly accomplished the adjustment process of processed hole centre-to-centre spacing; For keeping balance, the opposite side that on bushing plate, is provided with the slippage drill bushing also is provided with balance weight 10.Change the axle sleeve 11 on the positioning disk, just can adjust axial height.Dividing arm 12 is fixed on the lower surface of bushing plate, and index dial has the dividing gear 13 of 48 teeth and a calibrated dial 14 (as shown in Figure 5) to form by one, and calibrated dial is fixed on the dividing gear with rivet.As shown in Figure 4; Positioning disk comprises three spokes that are uniformly distributed with; Wherein first spoke 15 and second spoke 16 are horizontally disposed with, and the 3rd spoke 17 is provided with second spoke is vertical with first spoke, and an end of these three spokes is fixedly connected; On positioning disk, mark cross hairs, and guarantee the vertical, symmetrical of cross hairs as far as possible.During processing work 18, the workpiece of drawing good cross hairs is alignd with cross hairs on the positioning disk, with follower bolt it is pressed on the Drilling machines bench (not shown) then; Tighten second nut again and fix bushing plate, can on workpiece, process first hole, then unclamp second nut; On calibrated dial, find corresponding isodisperse, rotate dividing arm, insert in the corresponding teeth groove of dividing gear; Fix bushing plate, bore second hole, accomplish successively porose processing.Because of 48 being common multiples of numbers such as 3,4,6,8,12,16,24, so, just can realize the calibration of above-mentioned demands of different isodisperse easily, thereby satisfy the five equilibrium requirement of workpiece as long as dividing arm is inserted in the corresponding teeth groove of dividing gear.Between dividing arm and dividing gear, also be provided with spring 19, when boring, dividing arm located in teeth groove, can not be subjected to displacement, influence the indexing accuracy in hole.
Disk cover class part Universal Jig is compared with special-purpose drill jig; Maximum characteristics are exactly; Special-purpose drill jig can only a mould one; Promptly a secondary drill jig can only be processed the part of a kind of specification, a kind of structure type, and Universal Jig can be according to the designing requirement of part, all size that machining hole centre-to-centre spacing isodisperse difference, axial height parameters different, location element different, that be uniformly distributed with the hole are different and the disk cover class part of version.Realized one module multiple usages, Universal adjustable, the multinomial function that precision is controlled.For Multi-varieties and Small-batch Production, upgrading product are regenerated, new product development; Production time and manufacturing cycle have been shortened greatly; The flowing water manufacturing enterprise that also is fit to simultaneously not allow to shut down is used for rushing to repair fast operation, so this drill jig has extensive, practical application value.
