Amount production provides necessary condition.It in the past after workpiece finishes line, is installed with chuck by line, reprocesses inner hole.In
During correction, when adjusting two pawl being clipped on cylindrical surface, workpiece generates rolling, and the center line in scribing line hole is made to generate angle position
It moves, is difficult workpiece correction, and generate processing waste product.People have manufactured and designed clamping device thus, pass through the use of many years, effect
Fruit is fine.
As processing manufacturing industry rapidly develops, the precision and production efficiency requirement to process component are higher, show and add
Process is concentrated in work, and the form processing of people's multimachine, the multiple parts of a machine is widely adopted.Then tooling clamping device is wanted
It asks also higher and higher, pneumatic and hydraulic two kinds more advanced tooling clamping devices, the appearance of these advanced installation way occurs
The tradition positioning method that manually clamping adjusts is changed, machining accuracy is improved, processing non-cutting time is shortened, improves life
Produce efficiency.
For Mechanical Product's Machining, usual bulk article is if single processing, the much time on product clamping
Power, and Product Precision and dimensional uniformity it is difficult to ensure that, low efficiency.Existing fixture scheme is using fixture last time clamping one
Part product is processed, and the assembly and disassembly period is longer, and production efficiency is low.
Summary of the invention
For problem of the prior art, the present invention provides a kind of thin plate drilling tool fixture and its clamping method, this fixture
Automatic-clamping and simultaneously 4 workpiece of clamping can be achieved, improve clamping efficiency, reduce the working strength of worker, save the time, increase
Interests.
To achieve the above object, the present invention adopts the following technical scheme that:
A kind of thin plate drilling tool fixture, including bottom plate, three support plates, three support plates are fixed on lower surface of base plate,
It is used to support bottom plate, respectively left support plate, middle support plate and right support plate, the left support plate and right support plate are relative in
Support plate is symmetrical arranged；It is set on the bottom plate there are four clamping unit, four clamping units are arranged in sphere of movements for the elephants, and each clamping is single
First middle position is set as the location of workpiece, and the location of workpiece of each clamping unit is surrounded by positioning pin, and the positioning pin is solid
Due on bottom plate；It is equipped with a pressing plate in bottom plate left and right ends and each clamping unit corresponding position, each pressing plate is respectively connected with
One hydraulic cylinder, hydraulic cylinder is individually fixed on the outside of left support plate and right support plate, among the two pairs of clamping units laterally arranged
It is respectively provided with a pressing plate, two pressing plates are respectively connected with a hydraulic cylinder, and two hydraulic cylinders are individually fixed in the rear and front end of middle support plate,
Two pressing plates are respectively provided between the two pairs of clamping units vertically arranged, are commonly connected to a hydraulic cylinder, two hydraulic cylinders are fixed
In lower surface of base plate.
Further, the location of workpiece of each clamping unit is surrounded by 7 positioning pins.
Further, the pressing plate set on bottom plate left and right ends and the pressing plate among the two pairs of clamping units laterally arranged
It is Y shape pressing plate.
Further, the pressing plate between the two pairs of clamping units vertically arranged is T shape pressing plate, and two pairs of T-shaped pressing plate is equal
It is symmetrical arranged in " work " word.
The clamping method of the thin plate drilling tool fixture, which comprises the following steps:
1) workpiece to be processed is placed on the location of workpiece of bottom plate, is bonded with base surface by workpiece；
2) workpiece positions, after the completion of workpiece, workpiece to be processed is limited using positioning pin；
3) workpiece compresses, and after the completion of workpiece positioning, hydraulic cylinder operating drives hydraulic stem elongation, so that pressing plate pushes simultaneously, clamps
Workpiece；
4) clamping is completed, and starts to process four workpiece.
Fixture of the invention positions drilling-workpiece using bottom plate and positioning pin, and bottom plate and drilling-workpiece face paste are closed,
It can be improved rigidity, reduce deflection when processing, positioning pin can position in the horizontal plane drilling-workpiece, positioning is reliable,
It is convenient.Y shape pressing plate and T shape pressing plate is driven to be clamped drilling-workpiece by lever principle using hydraulic cylinder, platen design
At Y shape can multiple spot clamping, can also realize while 2 workpiece are clamped, internal at T-shaped increases of 2 platen designs is pressed from both sides
Close contact area clamps thin-walled parts more reliable and more stable.When needing to clamp, hydraulic stem extends in hydraulic cylinder, passes through thick stick
Bar effect, so that pressing plate pushes simultaneously, realizes the clamping of 4 workpiece, and after processing, hydraulic stem is withdrawn, so that pressing plate is lifted upwards
It rises, to unclamp 4 workpiece simultaneously, carries out quick-replaceable workpiece.
Compared with prior art, the beneficial effects of the present invention are: this fixture can realize Automatic-clamping and simultaneously clamping 4
Workpiece improves clamping efficiency, reduces the working strength of worker, saves the time, increases interests.
