Description
Technical field
The utility model relates to a kind of drill jig used when holing on the disk cover parts such as flange, axle sleeve, shaft coupling, belongs to metal working technical area.
Background technology
Having many in the workpiece that common vertical type rocker arm drilling machine is processed is disk cover parts, as flange, axle sleeve, shaft coupling etc., this type of part belongs to universal standard part, good interchangeability must be had, the site error of the bolt hole therefore on part, blind hole, unthreaded hole is sufficiently little, and this just requires that drill jig should have sufficiently high positioning precision.
The structure of tradition drill jig as shown in Figure 1, when utilizing this fixture to hole, the method of line can only be adopted to determine the position in each hole, because disk cover parts generally has centre bore, bad alignment point, work of therefore ruling is quite numerous and diverse, not only greatly reduces operating efficiency, and positioning precision cannot be ensured, thus have impact on the crudy of workpiece.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of drilling machine fixture, while guarantee dish sleeve workpiece crudy, improves the working (machining) efficiency of workpiece.
Problem described in the utility model realizes with following technical proposals:
A kind of drilling machine fixture, formation comprises gear-box, Large Gear Shaft, pinion shaft, gear wheel, pinion, ring-type backing plate and ring-type pressing plate, described gear-box is fixed on drilling machine platform, described Large Gear Shaft and pinion shaft are vertically placed, their lower end is connected with the bottom of gear-box by bearing through after the top board of gear-box, described gear wheel and pinion are positioned at gear-box, the two engage each other and respectively with Large Gear Shaft and pinion shaft coaxially affixed, described backing plate, workpiece and pressing plate are sleeved on the upper end of Large Gear Shaft successively and are fixed by the boss in Large Gear Shaft and nut, the upper end of described pinion shaft is provided with dial and handwheel.
Above-mentioned drilling machine fixture, is provided with the centring sleeve of ring-type in the centre bore of workpiece to be machined, is interference fits between the workpiece of described centring sleeve and its outside and the Large Gear Shaft of its inside.
Above-mentioned drilling machine fixture, between described Large Gear Shaft and the top board of gear-box, is equipped with axle sleeve between pinion shaft and the top board of gear-box.
The utility model by piece-holder on gear shaft, by the angle that dial and handwheel control panel sleeve workpiece differ between each hole, not only can ensure positioning precision and the crudy of workpiece, and the crossed process eliminated in conventional borehole technique, effectively improve the working (machining) efficiency of drilling machine.In addition, the utility model also has the advantages such as structure is simple, with low cost, installation and maintenance is convenient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of traditional drill jig;
Fig. 2 is structural representation of the present utility model.
In figure, mark is as follows: 1, drilling machine platform, and 2, T-shaped bolt, 3, backing plate, 4, workpiece, 5, pressing plate, 6, nut, 7, axle sleeve, 8, Large Gear Shaft, 9, bearing, 10, pinion shaft, 11, gear-box, 12, dial, 13, handwheel, 14, centring sleeve, 15, pinion, 16, gear wheel.
Detailed description of the invention
Referring to Fig. 2, the utility model comprises backing plate 3, pressing plate 5, nut 6, axle sleeve 7, Large Gear Shaft 8, bearing 9, pinion shaft 10, gear-box 11, dial 12, handwheel 13, centring sleeve 14, pinion 15 and gear wheel 16.
Gear wheel 16 and pinion 15 to be separately fixed on Large Gear Shaft 8 and pinion shaft 10 and to engage each other, and two gears all adopt standard module to design.Dial 12 is provided with graduation mark, and gear-box 11 is provided with the pointer corresponding with the graduation mark on dial 12 or groove.The effect of centring sleeve 14 guarantees that workpiece 4 is coaxial with Large Gear Shaft 8, this device can be made to adapt to the dish sleeve workpiece of different inner diameters by changing centring sleeve 14.During rotation hand wheel 13, the angle turned over by observing dial 12 just can know the angle that workpiece turns over.The utility model can carry out the Drilling operation of the disk cover parts such as flange, axle sleeve, shaft coupling easily and quickly.
The course of work:
This device to be placed on drilling machine platform and to be fixed with bolt, the backing plate 3 of annular to be sleeved in Large Gear Shaft 8 and to be placed on the boss in Large Gear Shaft 8, again workpiece 4 and pressing plate 5 are placed on backing plate 3 top successively, and be fixed (if the center-hole diameter of workpiece 4 is greater than the diameter of Large Gear Shaft 8 with nut 6, need between workpiece 4 and Large Gear Shaft 8, install suitable centring sleeve 14 additional, workpiece 4 is made to keep coaxial with Large Gear Shaft 8), then can hole.After completing the processing in first hole, by handwheel 13 turning of work piece 4 dial 12, make workpiece 4 turn over angle aft-loaded airfoil second hole of regulation, process second hole aft-loaded airfoil the 3rd hole, until all hole machined are complete.
Utilize the technical process that the utility model is holed:
1) this fixture and workpiece are installed on drilling machine;
2) rotary dial, completes the processing in hole successively.
The utility model has broken the conventional machining process of dish sleeve workpiece, improves machining accuracy and the working (machining) efficiency of drilling machine.This fixture can provide safeguard for the Drilling operation of the disk cover parts of different circle-dividing diameter, different hole count.Fixture main feature is as follows: circular hole class workpiece can carry out locating fast, accurately by (1) centring sleeve, and ensures not offset.
(2) for the workpiece that center-hole diameter is different, reliable clamping can be realized by the mode changing centring sleeve, improve the versatility of fixture.
(3), when processing dissimilar workpiece, only initial workpiece workpiece need be carried out tool setting and drill press spindle and fixture are fixed, tool setting need not be carried out to all workpiece.
