Description
Technical field
The utility model relates to screw compressor and manufactures processing technique field, specifically, relates to a kind of for the clamp structure in moving plate of scroll compressor processing.
Background technology
The requirement of the machining accuracy of the Moving plate in screw compressor is higher, comprises the requirement of the aspect such as the depth of parallelism, the roughness on molded line surface, the height of molded line at the coordinate position to vortex lines, the start angle of molded line, the outline line of molded line, the perpendicularity of molded line, vortex lines bottom surface and its back side.Because processing technology difficulty is large, common process equipment cannot reach its requirement, so the time that screw compressor enters mass production is not long.
Moving plate processing is except the requirement to equipment, and location and the clamp method of Moving plate vortex lines machining also have a huge impact machining accuracy.The location of Moving plate adopts the structure of two pin one sides usually, to ensure positioning precision.
Traditional clamp method has two kinds: a kind of is the cylindrical clamping Moving plate, as shown in Figure 1, Moving plate 1 is arranged on the locating surface of positioning body 2, jaw 3 carries out the action clamped in radial direction, cutter 4 carries out Milling Machining, generally, the chucking power of jaw 3, clip position and responsiveness can not be completely the same, cause Moving plate 1 and positioning body 2 not to fit completely, easily make Moving plate 1 leave the locating surface at the back side and produce inclination, affect machining accuracy.Another kind is the end face of clamping Moving plate, as shown in Figure 2, Moving plate 1 is installed on the locating surface of positioning body 2, jaw 3 is in the action axially carrying out clamping, cutter 4 carries out Milling Machining, the chuck of jaw 3 sinks in groove 5, its end face should lower than the end face of Moving plate, location is reliable, but the difficulty of depositing in design, because the end face of the vortex lines of Moving plate and vortex lines must be processed simultaneously, when clamping its end face, groove 5 must be processed in advance in blessing position, because the gauge of Moving plate card is less, groove 5 can not be excessively dark, which limits the thickness of jaw, make jaw position because the problem of chucking power often produces fracture, in some cases, due to the problem of product structure, Moving plate end face can the position of machined grooves very little, therefore the yields of this method is not high.
Utility model content
The purpose of this utility model is to provide a kind of for the clamp structure in moving plate of scroll compressor processing, can realize accurately location at a high speed, efficiently, and structure is simple, easy to operate.
The purpose of this utility model is achieved in that
For the clamp structure in moving plate of scroll compressor processing, Moving plate is arranged on positioning body, has a passage in the centre of described positioning body, and described passage is by pipeline and vacuum control anatomical connectivity.
When behind Moving plate location, realize the absolute pressure reduction of the Moving plate back side by vacuum control structure and want vacuum state, like this under outside atmospheric pressure, the Moving plate back side and positioning body can realize close contact, achieve and accurately locate and clamp, cutter carries out processing operation, after process finishing, pressurizeed to the gas injection of the Moving plate back side by vacuum control structure, Moving plate ejects from positioning body again.
Wherein, described vacuum control structure comprises the vacuum forming apparatus for extracting gases and the gas injection structure for injecting gas.
Described vacuum forming apparatus can be vavuum pump or vacuum tank, or other can vacuum device, as long as can remain vacuum state in process; Described gas injection structure can be the gas injecting pipe be connected with external compression air.
Wherein, the cooperation place between described positioning body and Moving plate is provided with hermetically-sealed construction.
Particularly, on positioning body, be provided with seal groove with the cooperation place of described Moving plate external diameter, described seal groove is embedded with sealing ring.The cross section of sealing ring can be circular, square or other is special-shaped.
The utility model is owing to have employed technique scheme, compared with prior art there is following beneficial effect: the utility model is by forming the passage be connected with external vacuum control structure at the middle part of positioning body, vacuum mode is adopted to realize positioning and clamping, machine rear compressed air Equilibrium vacuum and Moving plate is ejected from positioning body, make the utility model clamp structure can realize the accurate location of Moving plate, the integrality in the large face of Moving plate vortex lines side can be kept, reduce the processing of groove, simultaneously can also rapid material-feeding clamping and rapid release blanking.
Accompanying drawing explanation
By following embodiment of the present utility model and description taken together with the accompanying drawings, other advantage of the present utility model and feature are shown, this embodiment provides by way of example, but is not limited to this, wherein:
Fig. 1 is the structural representation of a kind of clamp structure of the prior art;
Fig. 2 is the structural representation of another kind of clamp structure of the prior art;
Fig. 3 is the structural representation of a kind of preferred embodiment of the utility model clamp structure.
Detailed description of the invention
As shown in Figure 3, for the clamp structure in moving plate of scroll compressor processing, Moving plate 1 is arranged on positioning body 2, is provided with seal groove 9 with the cooperation place of Moving plate 1 external diameter, seal groove 9 is embedded with sealing ring 91, and the cross section of sealing ring 91 can be circular, square or other is special-shaped.Have a passage 6 in the centre of positioning body 2, passage 6 is connected with vavuum pump 8 by pipeline 7, and meanwhile, pipeline 7 is also connected with external compression air by gas injecting pipe 71.Pipeline 7 is provided with switch 72, and for realizing the opening and closing of the pipeline between passage 6 and vavuum pump 8, gas injecting pipe 71 is provided with switch 73, for realizing the opening and closing of the pipeline between passage 6 and external compression air.
After Moving plate 1 is located, open switch 72, vavuum pump 8 vacuumizes to this device, Moving plate 1 back side absolute pressure is reduced and wants vacuum state, like this under outside atmospheric pressure, Moving plate 1 back side and positioning body can realize close contact, achieve and accurately locate and clamp, cutter 4 carries out processing operation; After process finishing, close vavuum pump 8 and switch 72, open switch 73, the pipeline between passage 6 and external compression air is opened, external compression air is to the pressurization of Moving plate 1 back side, and Moving plate 1 ejects from positioning body 2.
Although the utility model is illustrated hereinbefore according to preferred embodiment, but this does not represent that scope of the present utility model is confined to above-mentioned structure, as long as the equivalent substitution structure that those skilled in the art can develop easily after reading above-mentioned explanation, the equalization done under the spirit not departing from the utility model and scope changes and modifies, and all should be covered by within the utility model the scope of the claims.
