First positioning mechanism positions blank workpiece 13 using principle of six-point fixing.First positioning mechanism includes Anchor point X21, anchor point Y122, anchor point Z223, anchor point Z124, anchor point 25Z3 and anchor point Y226, the anchor point X21 is located on the right side of left side tooling main body 17, the anchor point Y122 be located at left side square protrusion and left side second On the opposite side of straight pin 20, the anchor point Z223, anchor point Z124 and anchor point 25Z3 are respectively positioned on bottom plate, and not On same straight line, the anchor point Y226 is located at the square protrusion side opposite with second straight pin 20 on right side on right side On.
The anchor point Z124 is 3mm lower with anchor point Z325 than anchor point Z223 in the height of Z-direction.All anchor points are equal Radius is 8mm and top is equipped with the straight pin for the chamfering that radius is 1mm, the protrusion of the anchor point Y122 and anchor point Y226 away from From for 3mm, anchor point Y122 and anchor point Y226 centre distance are 170mm.
The second station clamp body is used respectively including the first straight pin 31, third spacer pin 32, prismatic pin 30 and two In the second fixture unit for clamping 7 both ends of semi-finished product, the second tool unit includes third pressing plate 8 and third screw 9, the Three spacer pins 32 are installed on bottom plate, and the third screw 9 passes through third pressing plate 8, and end is connect with base thread, the third One end of pressing plate 8 is limited by third spacer pin 32, and the other end is for compressing semi-finished product 7,31 He of the first straight pin Prismatic pin 30 is installed on bottom plate and is located between two the first fixture units, the straight pin 31 and prismatic pin 30 and sole shape At plane and two pits for positioning semi-finished product 7.
Reinforcing rib 10 is equipped between the leading flank and bottom plate of the tooling main body 17.It is preferable by two reinforcing ribs 10 Solve 13 deep hole machining process of blank workpiece and allow the generation of knife phenomenon, the bounce of process cutter, cutting fluid spray less than Position, iron filings are difficult to the problems such as being discharged from pin hole.
As shown in figure 5, the first bottom plate 18 is installed on the bridge plate 6 of machining center before processing, the both ends difference of bridge plate 6 It is fixed on the L plate 2 of B axle 4 and the L plate 2 of tailstock 1, when processing different station, by rotating B axle 4.
Before first procedure of the milling face of progress drilling tapping, it is specific blank workpiece 13 need to be mounted on the first station clip On, as shown in figures 1 and 3, blank workpiece 13 is placed on six anchor points first, so that blank workpiece 13 and 6 positions Point comes into full contact with, and range estimation is very close to each other, and two of them third straight pin 20 plays the role of Auxiliary support, after placing correctly, The first screw 12 is first gently driven to carry out centering with hand, then with hand respectively by four the first pressing plates 11 and second pressing plate 15 It is placed in the correct position of blank workpiece 13, in order to enable four the first pressing plates 11 and second pressing plate 15 are located at blank workpiece 13 correct position needs to limit by the first spacer pin 19 and the second spacer pin 28, inevitable if the position of pressing plate pressure is not right Lead to the part rejection of processing.Then the second screw 14 and the first screw 12 are tightened, is successively locked finally by allen wrench Each screw, purpose is in order to be deformed blank workpiece 13 not, to improve the position of following process process threaded hole and pin hole Degree of setting.Wherein anchor point X21 limits the movement in the direction blank workpiece 13X, and anchor point Y122 and anchor point Y226 limit hair The movement in the direction base workpiece 13Y and the rotation of Z-direction, anchor point Z124, anchor point Z223, anchor point Z325 limit Z-direction Movement, the rotation of X-direction, the rotation of Y-direction, meet principle of six-point fixing.
After first procedure, by semi-finished product 7 by pin hole be positioned at the first straight pin 31 and prismatic pin 30 it On, the first straight pin 31 and prismatic pin 30 play the role of inspection to the first procedure milling face drilling tapping at this time, if first The pin hole that procedure milling face drilling tapping thread processing comes out produces deformation, and installation can be highly difficult, is processed by first step Two pin holes are difficult to be put among straight pin 31 and prismatic pin 30.The third pressing plate 8 of left and right two is passed through into left and right two with hand first It is put in correct position under the guidance of a third spacer pin 32, then successively tightens by hand two third screws 9, finally again with interior Die nut uniformly locks third pressing plate 8.
Above-mentioned first straight pin 31 and prismatic pin 30 play the role of plane and two pits positioning, limit the shifting of Z-direction on one side Dynamic, the rotation of X-direction, the rotation of Y-direction, the first straight pin 31 and prismatic pin 30 limit the shifting of the movement of X-direction, Y-direction Dynamic and Z-direction rotation, be using the first straight pin 31 and prismatic pin 30 because 2 holes that first step processes center away from There is error, with two pin centers away from it is not possible that very consistent, it is dry away from error, installation that rhombus pin exactly " gets out of the way " the two center It relates to, this meets principle of six-point fixing.
After semi-finished product 7 is placed on the second clamp body, while blank workpiece 13 being placed on the first clamp body, such as Shown in Fig. 3, after first step processes, then the second step is processed, and when after processing is completed, opening machine tool door, is unclamped Third screw 9 removes bracket, and processes all at this time all completes the process, then by the first procedure milling face drilling tapping Semi-finished product 7 is removed, and is put on the second clamp body, and this makes it possible to what is moved in circles process, and reduces process time.
The embodiment is a preferred embodiment of the present invention, but present invention is not limited to the embodiments described above, not In the case where substantive content of the invention, any conspicuous improvement that those skilled in the art can make, replacement Or modification all belongs to the scope of protection of the present invention.
