Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As depicted in figs. 1 and 2, a kind of cylindrical work clamping and positioning device includes lid 1, clamp system, elastic reset
Part and pedestal 4.The bottom of lid 1 offers the axially extending bore inserted for cylindrical work 7, and sidewall offers radial hole 101,
This radial hole 101 is connected with the cavity in lid 1.Clamp system is placed in the cavity of lid 1, by the stream from radial hole 101
The gas-powered entered, clamps the cylindrical work 7 inserted from axially extending bore.Elastic reset part is also placed in the cavity of lid 1,
For clamp system is resetted.Pedestal 4 buckle closure is on the opening of lid 1.
In the present embodiment, as it is shown on figure 3, clamp system includes piston head 2 and clamping 3.Wherein, piston head 2 is interior
Hollow two ends, portion are equipped with opening, and outer peripheral face is provided with flange 201, and piston head 2 is divided into upper and lower two parts by this flange 201.
Cavity within piston head 2 is from top to bottom in contraction-like, as it is shown on figure 3, this cavity within piston head 2 is Y-shaped.Live
Chock plug 2 is placed in the cavity of lid 1, the outside wall surface of flange 201 and cavity inner wall laminating, upper and lower two of piston head 2 in lid 1
The outer wall divided and lid 1 leave gap between the cavity wall of cavity.Radial hole 101 is positioned under flange 201, near piston head 2
Bottom.
Clamping 3 is from top to bottom in contraction-like, as it is shown on figure 3, this clamping 3 is inversed taper platform shape.This clamping 3 is placed in
In the cavity of lid 1, the little head end of clamping 3 is inserted into this cavity from the cavity big opening end of piston head 2, clamping 3
Outer wall be resisted against in this piston head 2 cavity wall.The end of the stub end of this clamping 3 is resisted against on the inwall of lid 1 bottom.Such as figure
Shown in 3, axially extending bore, piston head 2 and clamping 3 are coaxial.
In the present embodiment, as it is shown on figure 3, elastic reset part is helical spring 5, it is sleeved on the top of piston head 2, and one
End is resisted against on flange 201, and the other end is resisted against on the inwall of lid 1 bottom.In the outside of helical spring 5 and lid 1 lumen body
Wall leaves gap.
When air inlet is after radial hole 101 flows into, and air-flow promotes and moves on piston head 2, and clamping 3 is extruded, then will be from axle
The cylindrical work 7 inserted to through hole clamps and positions, and now helical spring 5 is compressed.Treat cylindrical work is processed
Cheng Hou, stops supplying to radial hole 101, and now, under the effect of helical spring 5 resilience force, piston head 2 is descending, clamping 3 pine
Relax, the most just cylindrical work 7 can be unloaded.
Clamp system is in addition to using the structure provided in the present embodiment, it is possible to be designed to helical clamping structure, namely
Saying the part that piston head 2 and clamping 3 replace with two threaded engagement, the promotion next one part at air-flow rotates, extruding
Cylindrical work is clamped by another part.
The helical spring 5 also optional bottom being placed on piston head 2, one end is fixing with the bottom surface of this piston head 2 to be connected, separately
One end is fixing with the end face of pedestal 4 to be connected.So, when moving on piston head 2, helical spring 5 is stretched and accumulation of energy, when stop to
When radial hole 101 supplies, piston head 2 is retracted by helical spring 5, and clamping 3 relaxes, and the most just can be unloaded by cylindrical work 7.
Elastic reset part is in addition to using helical spring, it is possible to select polyurethane spring.
Owing to the motion of this clamping and positioning device is piston movement, accordingly, it is desirable to provide airtight environment, it is contemplated that seal
Problem, then, as shown in Figure 3, it is preferable that on lid 1 near opening part cavity wall on be provided with annular internal projection 102, should
The end face of annular internal projection 102 one end is concordant with the end face of lid 1 opening, and the other end is positioned under radial hole 101.In annular
The internal face of protruding 102 is fitted with the outside wall surface of piston head 2 bottom.For the sealing of further lifting device, further
Ground, this clamping and positioning device also includes sealing gasket 6, and this sealing gasket 6 is nested in annular internal projection 102, is positioned at the end of clamping 3
Between the end face of face and pedestal 4.
In order to reduce piston head 2 and annular internal projection 102 between friction, then, as it is shown on figure 3, piston head 2 bottom with
Two first annular grooves 202 being parallel to each other are offered in the outside wall surface that annular internal projection 102 fits.Same convex in order to reduce
Friction between cavity wall in edge 201 and lid 1, the outside wall surface of flange 201 offers two the second cannelures being parallel to each other
2011。
A kind of cylindrical work clamping and positioning device that the present embodiment is provided, compact conformation, it is active in one's movements, by pneumatic
Mode advance cylindrical work 7 clamping and positioning that axially extending bore from lid 1 inserts by clamp system, then by elastic reset part
Resetting clamp system, each parts are all placed in lid 1, so that whole device volume is little, occupy little space,
It is suitable for joining at the enterprising luggage of various kinds of equipment, can consolidate and accurately cylindrical work be positioned and clamp.
Obviously, above-described embodiment of the present utility model is only used to understand explanation this utility model example, and
It it is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.Here without also all of embodiment being given
