Description
Technical field
The present invention relates to machine tooling fields, and in particular to a kind of chucks of machine tooling.
Background technology
Workpiece needed after the completion of finishing at one end it is counter process another section, therefore often wrapped on tool after the completion of finishing
One layer of soft copper piece is wrapped up in, then carries out clamping again, it is therefore, very big for the consumption of soft copper piece, and wrap up inconvenient, work
Efficiency substantially reduces.
In addition, after soft clamping, the clamping force of workpiece can be reduced, the clamping to workpiece is cannot be satisfied, after leading to clamping
Influence the normal process of workpiece.

Three clamping jaw devices clamp, and each clamping jaw device includes a fixed plate, and the both sides of fixed plate are respectively set a sliding rail, every piece
A support leg is installed at the both ends of fixed plate respectively, and one end of the support leg is both provided with an accommodating chamber, and support leg passes through receiving
Chamber is installed in fixed plate, and more than one support leg encompasses a circular lock chamber, and workpiece setting is in circular fixation
Intracavitary is simultaneously fixed by more than one support leg, and fixed plate opposite piece side is provided with one layer of soft-touch
Layer.
The head of the support leg is respectively provided with a hook portion as a preferred technical solution, has in hook portion there are one installation cavity,
A spring is respectively mounted in installation cavity, the outboard end of the spring installs a compressed part, and compressed part one end is provided with an insertion section, inserts
Enter portion to be inserted in installation cavity and contact with one side end face of spring.
The soft-touch layer uses a soft copper piece as a preferred technical solution, is wrapped in the outboard end of fixed plate
On face.
The fixed plate and the arc-shaped shape of soft-touch layer as a preferred technical solution,.
The both ends of the support leg are respectively set there are one lock screw as a preferred technical solution, and support leg passes through
Lock screw locking is installed in the sliding rail of fixed plate both sides.
The beneficial effects of the invention are as follows：The present invention can be achieved to a variety of clamping modes of workpiece, it can be achieved that soft clamping and
Hard clamping has extraordinary clamping power after clamping, prevents loosening for workpiece.
Description of the drawings

Fig. 2 is the structural schematic diagram of the soft clamping state of the present invention；
Fig. 3 is the back structures schematic diagram of the support leg of the present invention；
Fig. 4 is the internal structure schematic diagram of the support leg of the present invention.
Coding in figure is respectively：1 is chuck main body, and 2 be fixed plate, and 3 be sliding rail, and 4 be support leg, and 5 be soft-touch
Layer, 6 be lock screw, and 7 be compressed part, and 8 be workpiece, and 9 be accommodating chamber, and 11 be spring, and 12 be installation cavity, and 13 be insertion section.
Specific implementation mode
As shown in Figure 1, the chucks of this machine tooling, including chuck main body 1, there are one 1 centre tools of chuck main body
Clamping chamber, workpiece 8 is set to clamping intracavitary, and is clamped by three clamping jaw devices that clamping intracavitary is uniformly arranged, each clamping jaw
Device includes a fixed plate 2, and a sliding rail 3 is respectively set in the both sides of fixed plate 2, and the both ends of every piece of fixed plate 2 are installed respectively
One end of one support leg 4, support leg 4 is both provided with an accommodating chamber 9, and support leg 4 is installed on by accommodating chamber 9 in fixed plate 2, and one
A above support leg 4 encompasses a circular lock chamber, and workpiece 8 is set in circular lock chamber and passes through more than one
Support leg 4 be fixed, 2 opposite piece side of fixed plate is provided with one layer of soft-touch layer 5.
As shown in figure 4, the head of support leg 4 is respectively provided with a hook portion, tool is there are one installation cavity 12 in hook portion, in installation cavity 12
It is respectively mounted a spring 11, the outboard end of spring 11 installs a compressed part 7, and 7 one end of compressed part is provided with an insertion section 13, insertion section
13 are inserted in installation cavity 12 and are contacted with 11 1 side end face of spring, and soft-touch layer 5 uses a soft copper piece, is wrapped in fixation
In the end face outside of plate 2, fixed plate 2 and the arc-shaped shape of soft-touch layer 5.
As shown in figure 3, the both ends of support leg 4 are respectively set there are one lock screw 6, support leg 4 is locked by lock screw 6
It is tightly installed in the sliding rail 3 of 2 both sides of fixed plate, support leg 4 can move in sliding rail 3, can pass through locking after the completion of mobile
Screw 6 is locked, and in hard clamping, is contacted with 8 outer surface of workpiece by more than one support leg 4, realizes multipoint positioning
It clamps, pressure is high, and clamping power is tighter, as shown in Figure 1.
As shown in Fig. 2, when needing to carry out soft clamping, lock screw is unclamped, support leg is flipped outward, exposes fixed plate
Workpiece, is incorporated between each fixed plate by the soft-touch layer 5 of one end at this time so that soft-touch layer 5 connects with 8 surface of workpiece
It touches, after entire support leg flips outward at this time, holddown spring is understood in the insertion section of 7 one end of compressed part, at this time compressed part and clamping chamber
Inner wall contacts, and under spring force so that one end of support leg contacts compression with workpiece surface, therefore is pressed from both sides by soft copper piece 5
It while tight, and can be compressed with workpiece surface by the support leg 4 at 5 both ends of soft copper piece, realize that dual fixation, soft copper piece are not damaged
Consumption, switching efficiency greatly promote.
The beneficial effects of the invention are as follows：The present invention can be achieved to a variety of clamping modes of workpiece, it can be achieved that soft clamping and
Hard clamping has extraordinary clamping power after clamping, prevents loosening for workpiece.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection domain should be determined by the scope of protection defined in the claims.
