Description
Technical field
The utility model relates to field of fixtures, in particular to a kind of collet stationary fixture.
Background technique
When being machined out operation to collet in the prior art, since the shape of collet is more complicated, lead to consolidating for collet
The structure of clamp tool designs more complicated and relatively low clamping operation timeliness rate.
Utility model content
In view of the deficienciess of the prior art, can disposably will be more the main purpose of the utility model is to provide one kind
A collet carries out collet stationary fixture that is quickly fixed or discharging.
To achieve the above object, the utility model provides following technical solution: a kind of collet stationary fixture, including bottom
Plate, is provided with several through-holes on the bottom plate, and the lower part of each through hole is provided with cylinder, the cylinder on the bottom plate
Including piston rod, big envelope is provided on the piston rod, the bottom plate top is provided with the fixed block for being fed through piston rod, described
The two sides of each fixed block are provided with collet, and the collet includes the cavity entered for fixed block, are provided on the bottom plate
Several locating slots placed for collet.
Preferably, the fixed block includes two protrusions being oppositely arranged, and the angle between two protrusions is 180 °, described
The thickness of protrusion is less than the thickness of cavity.
Preferably, the big envelope is nut, and the thread segment with nut cooperation is provided on the piston rod.
The utility model has the following advantages compared with the prior art, it is characterized in that can disposably by multiple collets into
Row is fixed, and principle is that the collet with cavity quickly can be clamped or be discharged by cylinder cooperation fixed block, wherein cylinder
When piston rod being driven to rise, big envelope has gap far from fixed block at this time between fixed block and cavity, it may be convenient to activity folder
Set, when needing to clamp, collet is aligned with locating slot, and fixed block enters in the cavity of collet at this time, then cylinder band piston
Bar decline, fixed block clamping collet steadily guarantee that collet is fixed by good, due to the setting of collet, so that fixed
Block is without departing from piston rod.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of collet stationary fixture of the utility model.
In figure: 1, bottom plate；2, cylinder；3, piston rod；4, big envelope；5, fixed block；6, collet；7, cavity；8, locating slot；9,
Protrusion.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of collet stationary fixture, including bottom plate 1, several through-holes are provided on the bottom plate 1, it is described
The lower part of each through hole is provided with cylinder 2 on bottom plate 1, the cylinder 2 includes piston rod 3, is provided on the piston rod 3
Big envelope 4,1 top of bottom plate are provided with the fixed block 5 for being fed through piston rod 3, and the two sides of each fixed block 5 are provided with
Collet 6, the collet 6 include the cavity 7 entered for fixed block 5, are provided with what several were placed for collet 6 on the bottom plate 1
Locating slot 8.
6 stationary fixture of a kind of collet of the utility model, it is characterized in that can disposably be consolidated multiple collets 6
Fixed, principle is that cylinder 2 cooperates fixed block 5 that can quickly the collet 6 with cavity 7 is clamped or be discharged, wherein cylinder 2
When piston rod 3 being driven to rise, big envelope 4 has gap between fixed block 5 and cavity 7 at this time far from fixed block 5, it may be convenient to living
Dynamic collet 6, when needing to clamp, collet 6 is aligned with locating slot 8, and fixed block 5 enters in the cavity 7 of collet 6 at this time, then gas
Cylinder 2 drives piston rod 3 to decline, the clamping collet 6 steadily of fixed block 5, guarantees that collet 6 is fixed by good, due to collet 6
Setting so that fixed block 5 is without departing from piston rod 3.
Preferably, the fixed block 5 includes two protrusions 9 being oppositely arranged, and the angle between two protrusions 9 is 180 °,
Raised 9 thickness is less than the thickness of cavity 7.The purpose being arranged in this way be can by the protrusion 9 of small volume it is convenient into
Enter in cavity 7, so that the cooperation between collet 6 and fixed block 5 is more convenient.
Preferably, the big envelope 4 is nut, and the thread segment with nut cooperation is provided on the piston rod 3.Spiral shell
Female design with thread segment can guarantee the connective stability of collet 6, and simple in construction, easy to disassemble and assemble.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
