A kind of processing tool of Machining of Vortex Disk of Vortex Compressor
Technical field:
The present invention relates to the processing tool of a kind of Machining of Vortex Disk of Vortex Compressor, belong to screw compressor
Technical field.
Background technology:
Scroll plate needs work in-process to sell the involute of the milling circle through revising in the heart, needs to ensure
The center of vortex lines and the center of scroll plate have two at a center, the so requirement to frock
Should position and clamp again.
The conventional mode that clamps is to use hydraulic pressure or pneumatic high-precision chuck to clamp scroll plate
At major diameter, locking post-treatment, this technique easily causes scroll plate clamping when and repeats
Position error, workpiece concordance is poor, crushes workpiece, and the depth of parallelism of scroll plate is very poor, and it is right to clamp
The requirement of operator is high, and frock makes costliness, and existing scroll plate uses aluminum alloy material system
Becoming, not only quality is soft, and is easily deformed, it is difficult to meet present Production requirement.
Summary of the invention:
For the problems referred to above, the technical problem to be solved in the present invention is to provide a kind of screw compressor
The processing tool of scroll plate.
A kind of processing tool of the Machining of Vortex Disk of Vortex Compressor of the present invention, it comprise clamp base,
Draw-in groove, pressing plate, pin, scroll plate, scroll plate step, sleeve, sleeve keyway, at the bottom of fixture
Being provided with draw-in groove on Zuo, be provided with pressing plate in draw-in groove, pressing plate is connected with cylinder main shaft, cylinder master
Axle is arranged in clamp base, and the upper surface lateral symmetry of clamp base is provided with two pins,
The position of the lower surface correspondence pin of scroll plate step is provided with pin-and-hole, and scroll plate step and folder
The mutual clamping in upper surface of tool base, the upper end of scroll plate step is provided with scroll plate, sleeve
Lower end is provided with sleeve keyway, and sleeve is set in folder by the position of sleeve keyway correspondence pressing plate
On tool base, the upper end of sleeve mutually compresses with scroll plate step.
As preferably, described scroll plate uses high-quality carbon element structural steel, have intensity high,
It is unlikely to deform the effect with corrosion resistance.
Beneficial effects of the present invention: its reasonable in design, simple to operate, easy to use, logical
Cross and use the mode of the drop-down locking of cylinder and the mode of scroll plate location, it is to avoid resetting
Error occurs, and cost is low, does not injure workpiece when clamping, and positioning precision is high, and the depth of parallelism is good, dress
Pressing from both sides convenient and swift, volume is little, can once clamp multiple scroll plate, decreases lathe sky and walks tool changing
Number of times, improves working (machining) efficiency, and processing concordance is high.

Detailed description of the invention:
As Figure 1-Figure 8, this detailed description of the invention is by the following technical solutions: it comprises
Clamp base 1, draw-in groove 2, pressing plate 3, pin 4, scroll plate 5, scroll plate step 6, set
Cylinder 7, sleeve keyway 8, clamp base 1 is provided with draw-in groove 2, is provided with pressure in draw-in groove 2
Plate 3, pressing plate 3 is connected with cylinder main shaft, and cylinder main shaft is arranged in clamp base 1, fixture
The upper surface lateral symmetry of base 1 is provided with two pins 4, the lower surface of scroll plate step 6
The position of corresponding pin 4 is provided with pin-and-hole, and the upper end of scroll plate step 6 and clamp base 1
The mutual clamping in face, the upper end of scroll plate step 6 is provided with scroll plate 5, and the lower end of sleeve 7 sets
It is equipped with sleeve keyway 8, and sleeve 7 is set in by the position of the corresponding pressing plate 3 of sleeve keyway 8
In clamp base 1, the upper end of sleeve 7 mutually compresses with scroll plate step 6.
Wherein, described scroll plate 5 uses high-quality carbon element structural steel, has intensity high, no
The yielding effect with corrosion resistance.
The operation principle of this detailed description of the invention: when cylinder moves downward, pressing plate 3 can be along
Draw-in groove 2 downwards, thus blocks at the step of sleeve 7 lower end, and band moving sleeve 7 is downwards by vortex
The scroll plate step 6 of dish 5 lower end is tightly secured in the clamp base 1 at two pin 4 places
In the plane of end, pull down due to ring-type, and unlike conventional frock uses three or four soft pawls
Clamp, only 3 or 4 stress, cause workpiece discontinuity, crush and arch change
Shape etc., so scroll plate 5 uniform force, the completely plane with two pin places are fitted, tool
There is the highest depth of parallelism.
This detailed description of the invention reasonable in design, simple to operate, easy to use, by using
The mode of the drop-down locking of cylinder and the mode of scroll plate location, it is to avoid the error of resetting is sent out
Raw, cost is low, does not injure workpiece when clamping, and positioning precision is high, and the depth of parallelism is good, convenient mounting and clamping
Fast, volume is little, can once clamp multiple scroll plate, decreases lathe sky and walks number of changing knife,
Improve working (machining) efficiency, processing concordance is high.
The ultimate principle of the present invention and principal character and the present invention excellent has more than been shown and described
Point.Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments, on
State the principle that the present invention is simply described described in embodiment and description, without departing from the present invention
On the premise of spirit and scope, the present invention also has various changes and modifications, and these change and change
Enter to both fall within scope of the claimed invention.Claimed scope is by appended power
Profit claim and equivalent thereof define.
