Fig. 1 is a kind of camshaft structure schematic diagram of model in the prior art;
Fig. 2 is a kind of structural schematic diagram of camshaft Pneumatic drilling fixture of the utility model;
Fig. 3 is the front view of Fig. 2;
Fig. 4 is the vertical view (partial perspective) of Fig. 2;
Fig. 5 is the side view of Fig. 2.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts The every other embodiment obtained, shall fall within the protection scope of the present invention.
The camshaft Pneumatic drilling fixture of the present embodiment is as shown in Figure 2-5, including:Pedestal 1, sliding sleeve, 3 columns 4, cylinder 6, cover board 7, bushing plate 8 and two supporting blocks, the first supporting block 21 and the second supporting block 22, two supporting blocks are fixed on pedestal 1 On, and be oppositely arranged, column 4 is fixed on pedestal 1, and sliding sleeve 3 can be axially slidably set in along column 4 outside column 4, cylinder 6 On pedestal 1,7 one end of cover board connects the cylinder head of cylinder 6, and the other end is fixed on 3 top of sliding sleeve, and bushing plate 8 is mounted on On cover board 7, and end is equipped with through-hole, is equipped with drill bushing 9 in through-hole, the axis of through-hole is perpendicular to (the i.e. axis of drill bushing 9 of pedestal 1 It is also perpendicularly to pedestal), and intersect vertically with the V-arrangement bracket line of centres in two supporting blocks.
Before drilling, cylinder 6 is started by cylinder control valve 11, bushing plate 8 is driven to rise, camshaft hole to be drilled is placed on the In one supporting block 21 and the second supporting block 22, upward, the end of bushing plate 8 abuts cam 301 to one of camshaft platform Axially position is realized in side.Then control cylinder 6 drives bushing plate 8 to decline to compress platform, to pressing cam axis, drill jig The bottom surface of 8 end of plate is completely attached to platform surface, and platform surface can be kept vertical with the axis of drill bushing 9, and through-hole Axis intersects vertically perpendicular to pedestal 1 (i.e. drill bushing is perpendicular to pedestal 1), and with the V-arrangement bracket line of centres in two supporting blocks, real Existing radial positioning, then drills to camshaft drill bit by drill bushing 9.
It can be seen that the side that the camshaft Pneumatic drilling fixture of the present embodiment is realized positioning and compressed using the up and down motion of cylinder Formula is processed, and drives cover board 7 and bushing plate 8 to compress camshaft to be processed using cylinder 6, and realize axial direction, radial positioning, and Drill bushing 9 is driven to be moved to above cam shaft platform to be processed, 9 bottom of drill bushing is close to the plane and is processed, and drilling is greatly improved Precision, and this fixture is convenient for mounting and clamping, is effectively reduced operator's labor intensity, improves production efficiency.
In the present embodiment, further include:Adjustable plate 5 and adjusting bolt 10, adjustable plate 5 between sliding sleeve inner wall and column 4, Adjusting bolt 10 passes through sliding sleeve wall to connect adjustable plate 5, and adjustable plate 5 is elastic between sliding sleeve 3 and column 4 for adjusting, and adjusts and closes Suitable elasticity is avoided when sliding sleeve 3 slides axially along column 4 and is subjected to displacement in the horizontal direction when drilling.
The cross section of column 4 is trapezoidal, and the cross section of 3 hollow space of sliding sleeve is trapezoidal, is designed with lathe sliding rail dovetail groove Function is similar, and cross section is that the area on two inclined-planes of trapezoidal column 4 is larger, increases the contact area with 3 inner wall of sliding sleeve, When sliding sleeve is moved axially along column 4, the traversing probability of sliding sleeve 3 is minimized, the precision of radial positioning is increased.
In the present embodiment, bushing plate 8 is equipped with strip-shaped hole, passes through strip-shaped hole to be mounted on cover board 7 by bolt, strip-shaped hole Installation site of the bushing plate 8 on cover board 7 can be adjusted, to be adjusted according to the camshaft of different size so that through-hole Axis intersect vertically perpendicular to pedestal 1, and with the V-arrangement bracket line of centres in two supporting blocks, that is, the axis in the hole drilled out with Cam shaft mandrel axis intersects, and ensures borehole accuracy.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
