Be used to process the mould that accounts for of valve body inclined hole
Technical field
The present invention relates to field of machining, specifically relate to a kind of mould that accounts for that is used to process the valve body inclined hole.
Background technology
The processing of valve body inclined hole is adopted the processing method of five machining centers at present mostly, but is utilized five Cutter Body Processing with Machining Center parts to programme and to debug, and these all are complicated and loaded down with trivial details work.If there are not five machining centers, and also do not have condition to adopt under the situation of special plane, such inclined hole processing just can not solve, even adopted the said equipment, but investment is big, can't regain if not producing then investment in batches, thereby the cost height, inefficient problem.
The utility model content
One of technical problem to be solved by this invention provides a kind of mould that accounts for that is used to process the valve body inclined hole, to solve the cost height that needs five Cutter Body Processing with Machining Center in the prior art and produce, inefficient defective.
For addressing the above problem, the present invention adopts following technical scheme to realize:
Be used to process the mould that accounts for of valve body inclined hole, comprise drill jig base and the bushing plate that is positioned at this drill jig base top, described drill jig base is provided with a boss, this boss is provided with an inclined-plane, be provided with a valve body locating hole on boss, described valve body locating hole is perpendicular to the inclined-plane, and described bushing plate is provided with and accounts for cover, the center line and the valve body hole centre line that account for cover intersect formation angle β, and the described center line that accounts for cover is L with the vertical range that accounts for the center line of pattern hole locating hole.
Accounting on the described bushing plate is provided with the location drill bushing that accounts for the cover concentric with this in the cover.
Described drill jig base is provided with and is used for the auxiliary fabrication hole that calculates locating hole on the bushing plate, this fabrication hole in the valve body locating hole in the heart.
Described drill jig base is connected with bushing plate by column, and described column lower end is fixedlyed connected with the drill jig base, and the column upper end is provided with positioner, and bushing plate and this positioner are slidingly matched.
Described positioner comprises cylinder alignment pin and rhombus alignment pin.
The center of described fabrication hole and the vertical range between the inclined-plane are 50mm, and the vertical range between the center of fabrication hole and the cylinder alignment pin is 48mm.
Described drill jig base is connected with column with straight pin by screw respectively.
Described valve body locating hole is provided with lining and location pinching screw.
Described drill jig base is provided with the bolt hole that is communicated with locating hole, is provided with hanging bolt in this bolt hole.
The gradient of the inclined hole to be processed on the gradient on the inclined-plane of drill jig base and the valve body equates.
Adopt such scheme, because the center line of having determined locating hole and the center line of valve body locating hole intersect the vertical range L of the intersection point on the center line of the angle β of formation and locating hole and inclined-plane to the center line of valve body locating hole, thereby can guarantee to locate the residing position of drill bushing just in the position in to be processed hole to be processed.Column is slidingly matched by cylinder alignment pin and rhombus alignment pin and positioner, can guarantee that the center of fabrication hole and the vertical range between the cylinder alignment pin are 48mm, reduces the center of fabrication hole and the error of the vertical range between the cylinder alignment pin.The workpiece lining that is used for the auxiliary clamping workpiece that is provided with can prevent the valve body locating hole and wear and tear for producing between the workpiece.Screw, straight pin and the hanging bolt that is provided with can prevent that being connected of drill jig base and column is loosening.
The beneficial effects of the utility model are: need not five machining centers and process the valve body inclined hole, cost is low, precision and efficient height.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, be used to process the mould that accounts for of valve body inclined hole, comprise drill jig base 1 and the bushing plate 3 that is positioned at this drill jig base 1 top, described drill jig base 1 is provided with a boss 10, this boss 10 is provided with an inclined-plane, on boss 10, be provided with a valve body locating hole 4, the accent of valve body locating hole 4 is positioned on the inclined-plane, valve body locating hole 4 is arranged on the boss 10 obliquely, described bushing plate 3 is provided with and accounts for cover 5, this accounts for the center line of cover 5 and the center line of valve body locating hole 4 intersects formation angle β, the described intersection point that accounts for cover 5 center line and inclined-plane is L to the vertical range of the center line of valve body locating hole 4, accounting on the described bushing plate is provided with the location drill bushing 6 that accounts for cover 5 concentrics with this in the cover 5,4 are provided with lining 7 and location pinching screw in the described valve body locating hole.Described drill jig base is provided with and is used for the auxiliary fabrication hole 8 that accounts for cover 5 on the bushing plate that calculates, this fabrication hole 8 is communicated with valve body locating hole 4, the center of described fabrication hole 8 and the vertical range between the inclined-plane are 50mm, and the vertical range between the center of fabrication hole 8 and the cylinder alignment pin 12 is 48mm.Described drill jig base 1 is connected with bushing plate 3 by column 2, fixedly connected with drill jig base 1 in described column 2 lower ends, column 2 upper ends are provided with positioner, bushing plate 3 is slidingly matched with this positioner, described positioner comprises cylinder alignment pin 12 and rhombus alignment pin 13, described drill jig base 1 is connected with column 2 with straight pin 9 by screw 11 respectively, described drill jig base 1 is provided with and accounts for cover 5 bolts hole that are communicated with, be provided with hanging bolt 14 in this bolt hole, the gradient of the inclined hole to be processed on the gradient on the inclined-plane of drill jig base 1 and the valve body equates.
During use, to be processed is placed in the valve body locating hole 4, the center line of determining to account for cover 5 intersects the angle β that forms with the center line of valve body locating hole 4 and accounts for the intersection point that overlaps 5 center line and the inclined-plane vertical range L to the center line of valve body locating hole 4, determine the center of fabrication hole 8 and the vertical range 50mm between the inclined-plane, vertical range 48mm between the center of fabrication hole 8 and the cylinder alignment pin 12, thereby guarantee that the residing position of drill bushing, location is just in the position in to be processed hole to be processed, that is:
Known: 30 ° of the crossing angles that forms of the center line of the center line of locating hole and valve body locating hole, the center line of locating hole and the intersection point on inclined-plane are to the vertical range 1.78mm of the center line of valve body locating hole, vertical range between the center of fabrication hole and the cylinder alignment pin is 48mm, and the center of fabrication hole and the vertical range between the inclined-plane are 50mm;
Try to achieve: the position dimension of location drill bushing.
Separate: L1=1.78 * cos30 °=1.54mm
L2=50×sin30°=25mm
L=L2-L1+48=71.459mm
Get 71.46mm
Solve: the location drill bushing is of a size of 71.46mm
