Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Base part bottom surface clamp for machining as shown in accompanying drawing 2 to accompanying drawing 4 includes bottom plate 1, and bottom plate 1 has been mounted side by side below
Three backing plates 2；Bottom plate 1 is installed above to be had locating piece 12, positioning component, holds down assembly and shockproof knife system；Locating piece is cylinder
Shape, three locating pieces are positioned to isosceles triangle, and the upper surface of cylinder is the locating surface of base part to be processed, pedestal to be processed
The back-off of part is placed on the locating surface, and its pedestal top plate 031 contacts with the locating surface.
Base part to be processed is pressed on the locating surface by described hold down assembly；Described hold down assembly is divided into two kinds,
One kind holds down assembly for bottom surface, and one kind is side compressing component；The bottom surface, which holds down assembly, pushes down the base of base part to be processed
Seat top plate 031, the side compressing component push down the base side boards 02 of base part to be processed.
The bottom surface holds down assembly including hinge briquetting, the pressing plate cylinder 17 of first axle bearing 14 and first, hinge briquetting
It is made up of the first pressing plate 22 and the two parts of the second pressing plate 23, the second pressing plate 23 generally L-shape, its one end and the first pressing plate 22
Connection, the other end are compression force side.It is the company of rotation between the center section of first pressing plate 22 and the first axle bearing 14
Connect, first, which ships and resell on another market, 19 is used as rotary shaft, and the side of the center of rotation of the first pressing plate 22 is connected with the second pressing plate 23, and opposite side is provided with
Mounting hole, second, which ships and resell on another market, 20 passes through mounting hole, and both ends are fixed on the first connector 15, and the first connector 15 is connected in first
On the expansion link of pressing plate cylinder 17；First pressing plate cylinder 17 is connected on bottom plate 1.The band of the first pressing plate cylinder 17 can so be passed through
Dynamic second pressing plate 23 compresses and loosened substrate part, convenient and swift, and a locating piece is corresponding with below the compression point of the second pressing plate
12, ensure the firm of compression.
The side compressing component includes hinge pressing plate 16, the pressing plate cylinder 24 of second hinge bearing 25 and second, the hinge
It is rotation connection between the center section of chain pressing plate 16 and second hinge bearing 25, the 3rd to ship and resell on another market 28 be rotary shaft, hinge pressing plate
The side of 16 center of rotation is pressing section, and opposite side is provided with mounting hole, and the 4th, which ships and resell on another market, 29 passes through mounting hole, and both ends are fixed
On the second connector 27, the second connector 27 is connected on the expansion link of the second pressing plate cylinder 24；Second pressing plate cylinder 24 is solid
It is connected on bottom plate 1.So hinge pressing plate 16 can be driven to compress and loosen substrate part by the second pressing plate cylinder 24, it is convenient fast
It is prompt；Three same side compressing components are provided with the periphery of base part, it is ensured that base part uniform force, firmly may be used
Lean on.
The positioning component includes alignment pin 13 and two groups of alignment pin support bases, and alignment pin support base is arranged on the bottom plate
On 1, the both ends of two alignment pin support seat supports alignment pins 13, and alignment pin 13 can plug relative to alignment pin support base；Work
Making alignment pin 13 under state passes through the circular hole on the strengthening wing 032 in base part to realize the positioning to whole base part；By
In the position positioning in the horizontal plane only needed to part, each base part is differed, it is therefore desirable to which alignment pin 13 is arranged to
The design that vertical direction can be adjusted voluntarily, therefore alignment pin support base includes pedestal 3 and floating locating piece 4, the positioning of floating
To be slidably matched between block 4 and the pedestal 3, glide direction is vertical direction, be provided with the floating locating piece 4 with it is described fixed
The through hole that the position diameter of pin 13 agrees with.It so can prevent base part from crossing positioning, bring the inconvenience of feeding, also avoid the damage to fixture
Evil.
Because base part is overall higher, if only fixing its pedestal top plate 031, base part base during being milled
Seat part can produce moderate finite deformation, so as to cause to shake knife phenomenon, it is therefore desirable to which shockproof knife system prevents this phenomenon.It is described shockproof
Knife system includes support block 8, holds out against cylinder 5 and cylinder jacking block 11, and the cylinder jacking block 11 is connected in the end for holding out against cylinder 5
Portion, the cylinder jacking block 11 are respectively held against the side on the both sides of the machined surface of base part to be processed with support block 8.The branch
Bracer 8 has two, is installed on lip block 7, and the lip block 7 is connected on bottom plate 1 by three pieces of supporting plates 6, often
There is one piece of reinforcement 21 to play booster action between individual supporting plate 6 and bottom plate 1.Holding out against cylinder 5 and cylinder jacking block 11 also has two groups,
Cylinder 5 is held out against in air cylinder fixed plate 10, the air cylinder fixed plate 10 is connected on bottom plate 1 by cylinder supports block 9.This
Sample can effectively prevent the shake knife phenomenon in process from the both sides in both sides clamping face to be processed, protect the milling cutter life-span, improve and add
Work precision and surface roughness.
The base part bottom surface clamp for machining of the present invention has that simple in construction, cost is low, passes through the reinforcement in base part
Hole on the wing is accurately positioned part, and is provided with shockproof knife system, can effectively prevent in milling process because part itself becomes
Shape produces shake knife phenomenon, not only protects cutter, and can ensure the flatness of machined surface.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
