Specific implementation mode
It is (left and right directions, upper and lower directions in being described below, preceding that the utility model is described in further detail below in conjunction with the accompanying drawings
Rear direction is identical as left and right directions, upper and lower directions, the front-rear direction in Fig. 2, and the direction far from reader is rear in figure).
It is the part drawing of the small axis to be processed as shown in Figure 1.As shown in Figures 2 to 4, a kind of for boring small axle diameter to hole
Process unit, including drill bushing 2, pressing plate 4, V-block 5, clamp body 8, bushing plate 10, studs 19 and single head stud 21, it is described
8 left and right ends of clamp body be respectively provided with installation ear mount, the screw rod of bolt 1 revolves after passing through the U type grooves of installation ear mount from bottom to top
There are nut 26, the nut of one 7 lower end of bolt to be matched with the T-slot of Drilling machines bench；A left side for 8 upper surface of clamp body
Right both ends by pin 1 and screw 17 respectively installation there are one the V-block 5 that groove is in left and right directions, two V-blocks 5
Middle vertical plane in the front-back direction is in the same vertical plane；It is installed by pin 3 15 and bolt 3 16 at the rear of 8 upper surface of clamp body
There are holder 9, holder 9 and 8 upper surface of clamp body perpendicular；The bushing plate 10 is mounted on by bolt 2 11 and pin 2 12
The upper end of holder 9, bushing plate 10 are parallel to 8 upper surface of clamp body, are equipped with by drill bushing screw 13 on bushing plate 10 described
Drill bushing 2；The lower end of the studs 19 is connect with 8 upper surface nose threads of clamp body, upper end is rotary with spiral shell after passing through pressing plate 4
Mother 1 is cased with spring 18 on the studs 19 between pressing plate 4 and clamp body 8；The lower end of the single head stud 21 and folder
Fit depressions in the front-back direction in specific 8 threaded connection, 4 lower surface of upper end and pressing plate.
The operation principle of the utility model：First process unit assembling is finished before processing, small axis blank is placed on V-block
In 5 slot, when placement, the positioning right side of small axis major diameter is made to be close to the left side of the V-block 5 on the left side, at this point, defining
Five degree of freedom of small axis blank, because processing of the small axle diameter completed to hole, is not necessarily to machining accuracy, it is only necessary to be connected to radial hole
, so the degree of freedom that small axis rotates about the axis thereof is not required to limit；4 compression end of pressing plate is placed on small axis, tightening nut
One 3 can be realized the clamping to small axis blank, start drilling machine and carry out drilling processing, after processing is completed, reversely rotate nut 1,
Small axis blank is unclamped, then changes next small axis blank, is so moved in circles, you can realizes batch production.
It is equipped with bushing 14 between drill bushing 2 and bushing plate 10, prevents drill bushing 2 and bushing plate 10 to be in direct contact, in cutting force
Under the action of deform, to make the machining accuracy of process unit decline.
It is adjacent on single head stud 21 at clamp body 8 and is rotary with nut 3 20, both play the role of positioning, can also prevent from cutting
Power is excessive, and the inclination of single head stud 20 is caused to cause process unit accuracy decline.
8 both ends of clamp body are respectively provided with two installation ear mounts, and four installation ear mounts are symmetrical two-by-two around, just
In making 8 all directions stress equalization of clamp body, the machining accuracy of process unit was not only ensured, but also be avoided that because unbalance stress leads to work
The relevant parts service life of process and equipment reduces.
The pressing plate 4 is A type groove face pressure plates, and selection standard part saves cost and time convenient for materials installation.
