Description
Technical field
The present invention relates to fraise jig field, and in particular to a kind of compound milling drill jig of forging.
Background technology
In mechanical field, similar to structure as reducer shell, i.e.,：Upper-lower casing is carried out by the bolt hole of both sides
Be connected, be internally formed power transmission shaft located space, using and its extensively, the forging stock of upper shell is being produced using forging method
After part, need to often Milling Process be carried out to its mounting surface, then be drilled and tapping, traditional mode of production are divided into three-step-march,
I.e.：Milling flat, drilling, tapping, most of processing staff need two sleeve clamps, i.e.,：Milling flat positioning fixture and drilling and tapping are determined
Position fixture, this processing mode cause process to increase, and then cause positioning precision difference and defective products the problems such as increasing, and some are special
Though fixture can realize clamped one time, typically may be only available for the workpiece that a certain size is fixed.
The content of the invention
It is an object of the invention to provide a kind of compound milling drill jig of forging, to solve the class referred in above-mentioned background technology
Decelerator upper shell structure caused clamping process in substep process is more, the problems such as repetitive positioning accuracy difference, also or
Special fixture does not adapt to the problem of size different housings clamping.
To achieve the above object, the present invention provides following technical scheme：A kind of compound milling drill jig of forging, including fixture bottom
Plate, the first backing plate, the second backing plate, pressing plate and workpiece backup plate, first backing plate and the second backing plate are slidably mounted on fixture bottom
On plate, the left and right face that workpiece is corresponded on first backing plate and the second backing plate is separately installed with the bolt for clamping workpiece
A, and one workpiece backup plate of connection is screwed in the side of the first backing plate and the second backing plate, the pressing plate is installed on the
The opposite side of one backing plate and the second backing plate, the pressing plate clamp workpiece by bolt B and are fixed on workpiece backup plate.
Backing plate is slidably mounted on clamp bottom board, is adapted to the demand of workpiece different length；
The two sides of workpiece, are separately installed with workpiece backup plate and pressing plate, and pressing plate is fixedly connected on processing using bolt
On part backup plate, the demand of workpiece different in width is adapted to.
Further：First backing plate and the second backing plate include：Upper padding plate and lower bolster, the upper padding plate use bolt
C is fixedly connected on lower bolster, and the bolt mounting holes on the lower bolster are mounting hole.
The bolt mounting holes of lower bolster are mounting hole, can adjust the relative altitude of upper padding plate and lower bolster, are adapted to and add
The demand of workpiece different height.
Further：Spring is set with the bolt B.
Further：The pressing plate has 2.
Further：The clamp bottom board, the first backing plate, the second backing plate and pressing plate are made using 45#.
Compared with prior art, the beneficial effects of the invention are as follows：
（1）The clamp structure is reasonable, and use and maintenance is convenient, and volume is light and handy；
（2）Milling flat, drilling and tapping three process can be achieved to complete in clamped one time, avoid repetitive positioning accuracy poor
The problem of, the quantity of defective products can be reduced；
（3）This fixture be applicable to different length, width, height workpiece clamping and positioning, realize the fixture
Recycling.
