Description
Technical field
The present invention relates to a kind of processing unit (plant)s and method for numerical control machining fixture location hole.
Background technology
Existing fixture positioning method is one side（Black skin）, two pin（Round pin, link pin）Positioning method.Ordinary circumstance
Under, there are two types of processing methods for the processing of the fixture positioning hole of the type：The first processing method：The fixture of first station first leads to
Common elastic finger setting blank hole is crossed, other processing contents that can be processed other than location hole are processed（Including
Two fabrication holes are positioned for next process）.First process after processing is completed, then product is put on second fixture,
With the fabrication hole positioning of first process processing, two blank location holes of reprocessing first fixture positioning, such mode increases
Add a fixture station, greatly increases fixture cost；Second of processing method：Positioning pin on fixture increases an oil cylinder, folder
After tool makes folder, positioning pin drop-down is shunk, and then reuses Tool in Cutting, which increases oil cylinder, increases fixture cost.
Invention content
It is an object of the invention to overcome above-mentioned limitation, to provide a kind of simple, traditional positioning method, it is used cooperatively
Dedicated cutting tool, it is only necessary to which the same process can complete the device and method of the processing of location hole.
The purpose of the present invention is achieved through the following technical solutions：A kind of processing for numerical control machining fixture location hole
Device, including process tool are processing part below process tool, are equipped with location key seat below processing part, in location key seat
Equipped with positioning pin, positioning pin lower end is connected with spring, and lower spring end is connected to inside positioning pin, and process tool one end is equipped with flat
Convex block.
A kind of processing method for numerical control machining fixture location hole, step are：A, part will be processed first with elasticity
Finger setting, and process blank hole on processing part；
B, location key seat is positioned over below processing part, the center line of positioning pin is overlapped with the center line of blank hole, in spring
Under the action of, positioning pin top half is located in blank hole；
C, process when, process tool decline is cut into blank hole, with the decline of process tool, process tool one end it is flat
Convex block end face touches the upper surface of positioning pin, then as the decline of process tool, spring are compressed, spring is due to self-acting
Upper end heads on positioning pin, continues to be decreased until that aperture machines completely with positioning pin.
Preferably, lower spring end is equipped with stroke locating piece.
In conclusion the present invention has the following advantages：General cutter front end is point of a knife, can directly be damaged with positioning pin contacts
The construction front end of bad positioning pin, the cutter is flat construction, can protect positioning pin；General spring positioning pin, in addition the structure
Cutter, with the use of the technique processing request can be met, and save fixture station or reduce the oil used on fixture
Cylinder quantity saves fixture cost of manufacture；Spring holder is conventional springs positioning pin, is made simply, failure rate is low, the dimension in later stage
It is also more convenient to repair replacement.

Specific implementation mode
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment
It is only used for explaining the present invention, be not intended to limit the scope of the present invention..
A kind of processing unit (plant) for numerical control machining fixture location hole as shown in Figures 1 to 4, including process tool 1,
1 lower section of process tool is processing part 2, and 2 lower section of processing part is equipped with location key seat 4, and positioning pin 5 is equipped in location key seat 4, fixed
Position 5 lower end of pin is connected with spring 3, and 3 lower end of spring is connected to inside positioning pin 5, and 1 one end of the process tool is equipped with flat convex block
6, positioning pin 5 can be protected not to be destroyed.
A kind of processing method for numerical control machining fixture location hole, step are：Part 2 will be processed first with resilient key
Positioning, and process blank hole on processing part 2；Location key seat 4 is positioned over 2 lower section of processing part, the center of positioning pin 5
Line is overlapped with the center line of blank hole, and under the action of spring 3,5 top half of positioning pin is located in blank hole；When processing, add
The decline of work cutter 1 is cut into blank hole, and with the decline of process tool 1,6 end face of flat convex block of 1 one end of process tool connects
Contact the upper surface of positioning pin 5, then with the decline of process tool 1, spring 3 is compressed, and spring 3 is pushed up due to self-acting upper end
Positioning pin 5, continues to be decreased until that aperture machines completely with positioning pin 5.3 lower end of spring is equipped with stroke locating piece,
Ensure hole machined in place.
The method of the present invention is still with traditional positioning method, but under the premise of not increasing fixture cost and the cost of charp tool,
Process and meet the technological requirement of product；Cutter is dedicated tool, and cutter structure has particular/special requirement, and it is bullet to need clamp locating pin
Property positioning pin, with the use of can just meet processing request；It is cut suitable for alloy product, does not influence processing efficiency and processing saves
It claps.
