Technical field
The present invention relates to the laser micro-machining technology field, relate in particular to a kind of accent bar of accurate adjustments of gas static pressure chuck air pressure.
Background technology
The gas-static chuck of self-adapting tube caliber profile, be that the gas of certain pressure is imported in the designed specific sealed air-space, gas pressurized makes chuck clamp tubing.When importing gas as shown in Figure 1, gas pressure is regulated by transferring bar 31, and transferring bar 31 to regulate air cavity pressure sizes is to move forward and backward by it, and corresponding air cavity 10 volume size are changed, and under the constant situation of the gas flow that feeds, has changed the pressure of gas.When air inflow was constant, it was long more to transfer bar 31 to put in, and corresponding air cavity 10 volumes are more little, and the air pressure that flows to this road air cavity is with regard to big more (pressure direction is shown in the direction of arrow among Fig. 1), and vice versa.Common accent bar 31 commonly used as shown in Figure 2, this accent bar 31 has following deficiency:
(1) need be at the long one section screw thread of accent bar 31 rear ends processing, promptly fine thread end 71 among the figure is installed the accent pole spacing circle 61 of sealing ring 51 and is transferred bar to be made of one, and causes common accent bar 31 body diameters bigger;
(2) this common accent bar 31 only revolves turn around (pitch) with it and makes and transfer the flexible segment distance of bar, is difficult to accurately control and transfers the flexible distance of bar, causes the pressure control inaccuracy of each air cavity, influences the stationarity and the kinematic accuracy of clamping; The gas flow that leads to each road air cavity is difficult to accurate control, causes spiral air cavity 10 formed atmospheric pressures not wait, and causes the clamping force that produces inhomogeneous;
(3) only rely on sealing ring 51 sealings, air-tightness is bad;
(4) knurled knob 41 of common accent bar 31 must come the turn operation by instrument, and a moving week of revolution is transferred the flexible pitch of bar, causes operation inconvenience.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
In conjunction with Fig. 1 and shown in Figure 3, the accent bar 32 of a kind of accurate adjustments of gas static pressure chuck air pressure that the embodiment of the invention provides comprises: the knob of Lian Jieing and be used to stretch into the rod member of air cavity successively, rod member is provided with thread segment.In conjunction with knob among Fig. 3 is knurled knob 42, and its width is convenient to the operator and is manually regulated accurately greater than the width of operator's finger; And thread segment is a fine thread end 72, is convenient to the adjusting inlet coupling with the gas-static chuck.And the initial end of thread segment is provided with sealing device; Be provided with differential head 82 between knurled knob 42 and the rod member, rod member is provided with the differential scale.
When importing gas as shown in Figure 1, gas pressure is regulated by transferring bar 32, and transferring bar 32 to regulate air cavitys 10 pressure sizes is to move forward and backward by it, and corresponding air cavity 10 volume size are changed, and under the constant situation of the gas flow that feeds, has changed the pressure of gas.When air inflow was constant, it was long more to transfer bar 32 to put in, and corresponding air cavity volume is more little, and the air pressure that flows to this road air cavity 10 is just big more, and vice versa.
The thread segment front end of rod member also is connected with deep section 92 that mates with air cavity.It is simple in structure, thereby the length of going deep into air cavity 10 is regulated the volume adjustments of gas pressure size in the air cavity 10.
Sealing device comprises O RunddichtringO 62, and rod member and O RunddichtringO 62 connecting portions are provided with annular groove (as shown in Figure 3), are used to block O RunddichtringO 62.
Present embodiment is preferred, and the accuracy of differential scale is 1um, can be higher so that adjust precision.
Transfer the ventilation inlet of the air cavity of bar to be provided with the gas electronic flowmeter, the gas pressure situation in can more effective accurate understanding air cavity 10 is convenient to adjust timely.
As can be seen from the above embodiments, the accent bar of a kind of accurate adjustments of gas static pressure chuck air pressure that the embodiment of the invention provides, comprise: the knob of Lian Jieing and be used to stretch into the rod member of air cavity successively, rod member is provided with thread segment, and the initial end of thread segment is provided with sealing device; Be provided with the differential head between knob and the rod member, rod member is provided with the differential scale.This regulating rod, its characteristics are as follows:
(1) swivel head that is similar to the differential head is adopted in the rear end, and rotating part indicates pointer, is carved with scale on the accent bar surface of pointer correspondence, and doing down scale is a lattice 1um, can accurately control the stroke of transferring bar, thereby accurately control air cavity pressure; (2) have seal groove on the accent bar, adopt the O-ring seals sealing, good sealing effect.(3) need not any instrument, manual adjustments; (4) easy to adjust, durable in use.
The new-type accent bar of each air cavity is led in above-mentioned control, can well realize leading to the accurate control of each air cavity air pressure, makes chucking power evenly, steadily, and is little to the clamping damage of tubing.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
