Abstract
A fixture for machining the vortex plate of vortex compressor is composed of a base plate and a clamping chuck. The base plate has smooth upper surface for bearing the template of vortex plate. The clamping chuck is a ring body whose diameter is less than the ring body of the said template for clamping the template with its outer peripheral surface in radiating mode. Its advantages are high correstness and stability of clamping the vortex plate, and high machining precision and efficiency.
Description
One, technical field
The present invention relates to a kind of vortex compressor working clamping device, particularly relate to a kind of frock clamp of processing screw compressor Moving plate and price fixing.
Two, background technology
As everyone knows, screw compressor is the device that a kind of gas savings also utilizes rotation that gas is compressed between helicla flute.Screw compressor mainly is made of price fixing and Moving plate, and price fixing is installed on the mainboard and has the spirality vortex filament; Moving plate is installed between mainboard and the price fixing, and has the crepe cord casket that is connected mutually with price fixing vortex casket.When Moving plate rotates with respect to price fixing, between vortex filament and line casket, form a pair of compression stroke; Be rotated when motion at Moving plate, this a pair of compression stroke constantly moves to the center, and its volume dwindles gradually, thereby the gas in the compression stroke is compressed and discharges.
As shown in Figure 1, Moving plate is made of template 1a and line casket 1b; Template 1a is discoid, and line casket 1b is positioned at the side of template 1a and forms involute shape.The structure of price fixing and Moving plate are similar and form discharge chambe with moving class interlock.The frock clamp that processing Moving plate (or price fixing) line casket 1b uses is generally ring-type and is made of bedplate 2 and a plurality of chuck 3 as shown in Figures 2 and 3; Bedplate 2 is used to support the template 1a of whirlpool dish 1, and chuck 3 then carries out radial location to template 1b periphery.The defective of this frock clamp is that when each chuck 3 fixing initial position inhomogeneous or template 1a is inaccurate, template 1a will misplace with bedplate 2, or the situation that the depth of parallelism reduces occur.For this reason, the outer peripheral face of template 1a is made " Contraband " shape holddown groove 1c and chuck 3 is inserted in the holddown groove 1c, and then move down chuck 3 and whirlpool dish 1 stably is fixed on the bedplate 2.The shortcoming of this scheme is, chuck 3 must radial and axial mobile could fixed form 1a, so control relative complex of chuck 3, frock efficient is also lower.
Three, summary of the invention
Purpose of the present invention promptly is a kind of vortex compressor working clamping device is provided, and it can be made things convenient for and fixed eddy plate stably when processing Moving plate or price fixing.
To achieve these goals, the present invention is designed to first inclined-plane with the outer peripheral face of vortex plate, and with the chuck leading arm of correspondence be designed to can with second inclined-plane of the first inclined-plane sliding-contact.
Based on above structure, only need move radially fixedly that chuck can make the whirlpool dish stably be fixed on the bedplate radial and axial moving simultaneously, both can improve the precision that the whirlpool dish is processed, can improve working (machining) efficiency again.
Be described in further detail below in conjunction with the technical characterictic of specific embodiment vortex compressor working clamping device of the present invention.
Four, description of drawings
Fig. 1 is the structural representation of traditional swirl compressor spinning disk.
Fig. 2, Fig. 3 are the schematic diagrames of existing vortex compressor working clamping device.
Fig. 4, Fig. 5 are the enforcement illustrations of vortex compressor working clamping device of the present invention.
Five, the specific embodiment
As Fig. 4, shown in Figure 5, vortex compressor working clamping device of the present invention is a diameter less than the annular solid of the template 11 of whirlpool dish 10, by bedplate 20 and fixedly chuck 30 constitute.Bedplate 20 is used to support the template 11 of whirlpool dish 10, and fixedly chuck 30 then makes template 11 outer peripheral faces become radial location, with the vortex filament casket 12 of processing whirlpool dish 10.The outer peripheral face of template 11 forms a gathering sill 13 and is used for being slidingly matched with the fixing leading arm 31 of chuck 30, and the both sides up and down of gathering sill 13 are respectively equipped with the first inclined-plane 13a and 13b and form the inner corner trim wedge shape.Fixedly the inner of chuck 30 is the leading arm 31 that has the second inclined-plane 31a, with corresponding with the gathering sill 13 first inclined-plane 13a of template 11; Leading arm 31 also can be made the second inclined-plane 31a, 31b and become the external corner wedge shape.Certainly, also gathering sill 13 can be made the inner corner trim wedge shape, and leading arm 31 is made bevel (as shown in Figure 5); Perhaps gathering sill 13 and leading arm 31 are made equidirectional bevel or have the groove shape and the protruding arm shape at oblique angle.The upper surface of bedplate 20 should be smooth, with the template 11 of steady placement whirlpool dish 10.
Processing the whirlpool coiled 10 o'clock, the whirlpool should be coiled 10 with the cutting element secured in parallel.For this reason, earlier the template 11 of whirlpool dish 10 is placed on the bedplate 20 and position, thereby whirlpool dish 10 is fixed with the fixing outer peripheral face of 30 pairs of templates 11 of chuck.In this process, fixedly chuck 30 each leading arm 31 downsides second inclined-plane 31a slide when inserting the template 11 outer peripheral face gathering sills 13 downsides first inclined-plane 13a, the first inclined-plane 13a of gathering sill 13 will oppress the second inclined-plane 31a of leading arm 31, thereby make template 11 simultaneously radially and move axially and be firmly fixed on the burnishing surface of bedplate 20.
This shows that fixedly 30 need of chuck radially move, whirlpool dish 10 radially is fixed on the bedplate 20 with moving axially simultaneously exactly, thereby improve the machining accuracy and the working (machining) efficiency of whirlpool dish.
Claims (4)
