Description
Technical field
It is specifically a kind of to realize the product processed in four axis horizontal milling machines in three axis the present invention relates to mechanical processing industry
The clamping tooling being processed on vertical knee-type milling machine.
Background technology
With the continuous development of China's Aeronautics and Astronautics cause, some complex-shaped anisotropic parts are more and more, to product
Demand it is also increasing, the requirement to process equipment also improves therewith.However in the actual production process, since the country is raw
Relatively backward, the objective condition limitation of enterprise's production of production condition and technology, there is：1. can not be obtained under current conditions limitation
It is required that process equipment；2. the arrangement of production task causes process equipment to occupy；3. equipment damage is asked in service mode etc.
Topic.Some can only be relied on the product of sleeping Milling Machining, once there is the above situation, the processing for directly resulting in product is stagnated, shadow
Ring the delivery on time of task.
Invention content
Dependence when processing anisotropic part to alleviate to horizontal milling machine, the present invention propose a kind of for turning sleeping Milling Machining
Change the clamping tooling of End Milling Process into.
The present invention includes hold-down support, pull rod and screw thread blanking cover.The hold-down support riser geometric center
The mounting hole of pull rod is stated, one end of pull rod is fixed in the mounting hole；The end of the pull rod other end is equipped with screw thread blanking cover；
The upper surface of the level board of the hold-down support is fixed with positioning sprue.The positioning sprue is located at riser inner surface side
And close to level board side long edge position.
The axial direction of the distance between the inner surface of screw thread blanking cover after assembly and the riser inner surface of hold-down support with workpiece
Length is adapted.
The hold-down support includes level board and riser.The riser is located at the upper surface of level board.In the fixed branch
The inner surface of the riser of seat has the groove for clamping workpiece, and the top half of the groove is rectangle, and lower half portion is arc, and should
The radius of arc is identical as the radius of workpiece.
Using the present invention, can realize in working special-shaped part from sleeping conversion of the milling to vertical milling, while can realize zero
The quick-clamping of part and positioning alleviate dependence of the processing part to horizontal milling machine.
The bottom plate of hold-down support in the present invention is rectangle, and there are one U-type grooves for each cloth in both ends middle section, are used for tooling
Set and Positioning；Vertical plate is rectangle, and middle section has a groove, and slot lower part is semi-circular shape, is used for the positioning of workpiece, slot
Centre is a threaded hole, the clamping with screw rod cooperation for workpiece.Screw thread blanking cover is mounted on to one end of workpiece, during pull rod passes through
Heart hole is connect with hold-down support, plays the role of clamping to workpiece.When work, tooling hold-down support, screw thread blanking cover and pull rod coordinate
Positioning and the clamping work of workpiece are completed, position block, positioning screw seat and positioning screw meet the positioning of workpiece and morpheme adds
Work requirement.
Compared with prior art, the advantageous effect that the present invention obtains is shown as：
(1) work pieces process switchs to vertical milling by sleeping milling, expands product processing method, and process equipment is changed by four axis horizontal boring and milling machines
For three shaft vertical milling machines, product is reduced to equipment requirement.Simultaneously because having broken away from the dependence to milling machine type, reaches indirectly and carry
The effect of high efficiency.
(2) the quick-clamping positioning of workpiece may be implemented,
(3) tooling is easy to operate, can guarantee that workpiece installation is stablized while quick-clamping, uniform force is processed
The deformation that journey generates is small, can ensure the machining accuracy of thin-walled parts.

Specific implementation mode
The present embodiment is a kind of for sleeping Milling Machining to be converted into the clamping tooling of End Milling Process, including hold-down support 1, fixed
Position sprue 2, positioning screw seat 4, pull rod 5 and screw thread blanking cover 6.There is pull rod 5 in the geometric center of the riser of the hold-down support 1
One end of mounting hole, the pull rod is bolted in the mounting hole；The end of the pull rod other end is equipped with screw thread
Blanking cover 6.The distance between the inner surface of screw thread blanking cover after assembly and the riser inner surface of hold-down support and the axial direction of workpiece 7 are long
Degree is adapted.
The hold-down support 1 includes level board and riser.The riser is located at the upper surface of level board.To ensure riser
Stability has bearing rib between the outer surface and level board of the riser.In the upper surface of the level board of the hold-down support
It is fixed with positioning sprue 2；The positioning sprue 2 is located at the level board upper surface of riser inner surface side；The positioning sprue
Close to level board side long edge position, it to be used for the positioning of workpiece 7.Have in the inner surface of the riser of the hold-down support and clamps workpiece
The top half of groove, the groove is rectangle, and lower half portion is arc, and the radius of the arc is identical as the radius of workpiece.
In the present embodiment, hold-down support, positioning sprue and positioning screw seat manufacture material are 45 steel, pull rod and screw thread blanking cover
Material is 30CrMnSiA；Workpiece 7 is processing part, which is long tube-like thin-wall component, and feature bottom is symmetrical there are two 180 °
It is oriented to and turns round, it is milling machine working position that this, which is oriented to button, is pane before processing, interface dimensions are 25mm × 25mm, at φ after processing
20 rounded faces, two are oriented to torsion and have higher symmetry requirement.
When actual processing, workpiece bottom boss is placed on pedestal vertical plane arc groove first, the two is having the same
Screw thread blanking cover is blocked workpiece right side by arc radius φ 250mm, and pull rod carries out spiral shell by blanking cover centre bore and bearing threaded hole
Line connects, and then coordinates positioning screw seat and positioning screw to position workpiece against positioning sprue on a guiding button；Further
It tightens screw rod and ensures that the left section of workpiece is close to hold-down support vertical plane, Set and Positioning finishes.Using three shaft vertical milling machines, to being oriented to
Twist into row Milling Process, after completion of processing, using the guiding processed turn round as anchor point with position that sprue abuts and screw is fixed,
It completes another guiding and turns round Milling Process.
