Description
Technical field
The present invention relates to a kind of machinery processing apparatus, particularly relate to the fixture of a kind of oblique top part that injection mold uses.
Background technology
Now, because plastic products are in the extensive use of electronics field, make in injection mold, a kind of have the oblique top part of inner snap fit shape more and more common.This type of part has interior snap fit and ramp-roof structure, and there is the angle of about about 10 ° in die cavity direction and profile direction, and appearance and size is less, and required precision is high.Usual employing numerical control mill or electric spark equipment machine, but during processing, clamping centering difficulty is larger.The method that usual clamping adopts is:
1., with vice clamping, by calculating the tangent value at angle of inclination, External Shape is put into specified angle aft-loaded airfoil.The method complicated operation, before processing, non-cutting time is long, and mortality is high.
2. with sinusoidal magnetic suction disc sticking, sinusoidal magnetic suction disc is flared to specified angle, part is adsorbed on sucker and processes.The method complicated operation, before processing, non-cutting time is long, and should not adopt this method having higher cutting force of numerical control mill.
Summary of the invention
In view of the deficiency that prior art exists, the object of the invention is to provide a kind of numerical control mill or electric spark equipment use, the fixture of a kind of oblique top part that high accuracy, high efficiency, convenient operation processing injection mold uses.
For achieving the above object, the present invention adopts following technical scheme: a kind of fixture of oblique top part, it is characterized in that: comprise base, fixed block, grip slide, draw pin nut, described fixed block is fixed on described base by screw and pin, the center of fixed block is provided with chute, described grip slide center is provided with slide rail, and the described pin nut that draws is placed in the both sides of the bottom of chute, slide rail insert after chute by screw with draw pin nut to be fixed together.
The front and back locating surface of described fixed block and the interior side-locating face of two shoulders are vertical plane, and the two upper side-locating face front portions of shoulder are inclined plane.
The outer side-locating face of described grip slide is vertical plane.
This apparatus design is ingenious, simple to operate, working stability, compact conformation, easy to process, applied widely, can be used for numerical control mill, spark machined and inspection use, and the machine that can realize corrects outward, the precision making to process oblique top part is increased to ± 0.01mm by ± 0.025mm, while processing cost reduces 10%, also reduce operator's work difficulty, ensure that the precision that oblique top part is processed and cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As Figure 1-4, a kind of fixture of oblique top part comprises base 1, fixed block 2, grip slide 3, draws pin nut 4, fixed block 2 is fixed on base 1 by screw and pin, the center of fixed block 2 is provided with chute 21, grip slide 3 center is provided with slide rail 31, draw pin nut 4 to be placed in the both sides of the bottom of chute 21, after slide rail 31 inserts chute 21 by screw with draw pin nut 4 to be fixed together.The front and back locating surface of fixed block 2 and the interior side-locating face of two shoulders are vertical plane, and the two upper side-locating face front portions of shoulder are inclined plane.The outer side-locating face of grip slide 3 is vertical plane.
During use, base 1 is by EROWA(SOdick.AM3ls spark-erosion machine tool) dog screw and EROWA(SOdick.AM3ls spark-erosion machine tool) spacer is fixed on lathe after being connected, by with two locating platforms, (locating platform is after the nose shape of oblique top part machines, remove with grinding machine) oblique top part 5 be contained between fixed block 2 and grip slide 3, the inner side of oblique top part 5 locating platform coordinates with the front and back locating surface of fixed block 2, interior side-locating face is takeed in the side of oblique top part 5 and two of fixed block 2 and the outer side-locating face of grip slide 3 coordinates, the bottom surface of oblique top part 5 coordinates with the inclined plane of fixed block 2, then by drawing the pin that draws of pin nut 4 to embed appropriate location in the chute 21 of fixed block 2, screwing the screw above grip slide 3, oblique top part 5 is fixed between fixed block 2 and grip slide 3.
The angle of inclination of fixed block 2 inclined plane is identical with the angle in the die cavity direction of oblique top part 5 and profile direction.
