Abstract
The utility model discloses a sealing pair processing machine for triaxial centrifugal metal sealing battery valve, which comprises a machine frame, a drive element, a fixture, a cutter rack and a cutter. The cutter rack is fixed on a moveable rack below the cutter rack. The moveable rack consists of a horizontal slideway and a sliding plate in the slideway. An explorator element is arranged below the moveable rack. The explorator element also comprises a horizontal slideway and a sliding plate in the slideway. An elastic rack and an explorator are arranged on upper end of the sliding plate. The sliding plate is provided with the frame, and the frame is provided with a bearing which contacts the exploratory. A rotating shaft is penetrated through the elastic rack and connected with the drive element. The processing machine is characterized in that: 1. the two components used in processing the sealing pair are produced by the same exploratory with uniform positioning benchmark, consistent geometric shape of the two components and good sealing effect; 2. the two components of the sealing pair has reliable localization, accurate size measurement, high accuracy of size. Moreover, sealing point of the sealing pair can be easily adjusted, and bidirectional sealing of the product can be easily achieved.
Description
Technical field
The utility model relates to a kind of mechanical special processing equipment, and machining tool is paid in especially a kind of three-dimensional eccentric metal sealed butterfly valve sealing.
Background technology
Present domestic still do not have similar lathe and similar devices are used for the sealing of machining 3 D eccentric metal sealed butterfly valve and pay.Therefore can't compare, have only a kind of this type of lathe of part in addition of processing, anchor clamps are as a comparison.
For three-dimensional eccentric metal sealed butterfly valve, its most critical also is the parts of decision product quality quality, be exactly that the metal sealing is paid, these parts are ellipse cones of off-centre that place valve central authorities, for sealing the surface of paying, promptly be an ellipse garden conical surface (its eccentric angle is looked the valve aperture size, and selects between 20 °～30 °).This ellipse garden conical surface, process on conventional lathe is the comparison difficulty.
Present processing method is: on engine lathe, design anchor clamps, with the angle of the oblique needs of other part pad of processing, process with manual feed.
The weak point of this processing method is:
1, the geometries of part are inconsistent in addition to cause sealing to pay two by the influence of many-sided factor (as: the valve body variable thickness causes, the equal reason of the valve body two ends depth of parallelism).
2, the location benchmark disunity of two other parts is paid in sealing, thereby the precision of processed finished products is affected.
3, solid difficulty is surveyed in the measurement of size, and the precision of other part of influence processing.
4, owing to after the oblique workpiece of pad, increase length of cut, work efficiency is low.
5, be interrupted cut from start to finish, machined surface fineness is poor.
6, the part center can't accurately be determined in addition, brings difficulty to assembling, thereby the direct result that brings is exactly the difficult quality raising of product.
The utility model content
The purpose of this utility model provides the high three-dimensional eccentric metal sealed butterfly valve sealing of a kind of machining accuracy and pays machining tool.
The technical solution of the utility model is: machining tool is paid in a kind of three-dimensional eccentric metal sealed butterfly valve sealing; comprise frame; actuating unit; anchor clamps; knife rest and cutting knife; knife rest installs on thereunder the movable stand; this movable stand is made up of horizontal slideway and the upper slide that is contained in the slideway; below movable stand, install a pattern mechanism; this pattern mechanism is made up of horizontal slideway and the lower skateboard that is contained in the slideway; in the upper end of lower skateboard elastic shelf and pattern are housed; support is housed on lower skateboard, bearing is housed on support, bearing contacts with pattern; one rotating shaft is passed elastic shelf and pattern and actuating unit and is linked, and upper slide and lower skateboard are associated in together by bolt.
The characteristics of this machining tool:
1, processing sealing pay two in addition parts finish with same pattern, therefore processing location unifying datum, two other geometries of part are in full accord, thereby make the final good sealing effect of product.
2, it is reliable that two other part processing location are paid in sealing, and dimensional measurement is convenient accurate, is easy to improve dimensional accuracy, and the seal point that sealing is paid is easy to adjust, and the two way seal of product reaches easily.
3, becoming interrupted cut improves easily into cutting other part fineness continuously.
4, length of cut is short, increases work efficiency.
5, the part center is determined easily in addition, and is easy to assembly.
6, collect turning, grinding and polish in a lathe, saving of labor, the product precision that saves time improve easily.
The economic benefit of this machining tool
1,, makes length of cut shorten (length of cut be former processing method 1/5～1/20) greatly and just shortened process time greatly that to the lathe depreciation, power consumption etc. also reduce relatively because the processing method difference.
2, the most important thing is to improve the product retaining, precision improves, and from the use aspect, can substitute the import like product fully, has improved selling price (5～8 times) greatly.
Description of drawings
Fig. 1 is the structural representation of machining tool,
Fig. 2 is the structural representation of pattern mechanism.
The specific embodiment
Structure of the present utility model such as Fig. 1; shown in Figure 2: as to comprise frame 1; actuating unit 2; anchor clamps 3; knife rest 4 and cutting knife 5; knife rest 4 installs on thereunder the movable stand; this movable stand is made up of horizontal slideway 6 and the upper slide 7 that is contained in the slideway; below movable stand, install a pattern mechanism; this pattern mechanism is made up of horizontal slideway 6 and the lower skateboard 8 that is contained in the slideway; elastic shelf 9 and pattern 10 are housed in the upper end of lower skateboard 8; support 11 is housed on lower skateboard 8; bearing 12 is housed on support 11; bearing 12 contacts with pattern 10, and elastic shelf 9 is passed in a rotating shaft 13 and pattern 10 links with actuating unit 2.Spring 14 is housed below elastic shelf 9, and spring 14 lower ends and lower skateboard 8 link.Upper slide 7 and lower skateboard 8 are associated in together by bolt.
The course of work: actuating unit 2 is passed to rotating shaft 13 in the pattern mechanism with power; rotating shaft 13 drives pattern 10 rotations moves forward and backward lower skateboard 8 generations; the upper slide 7 that drives its top also moves forward and backward; move thereby knife rest 4 on the movable stand and cutting knife 5 are produced, the amount of movement of cutting knife 5 is determined to that is to say that by the shape of pattern 10 shape of the machining shape of 5 pairs of workpiece of cutting knife and pattern 10 is in full accord.Utilize that this machining tool processing sealing pays two in addition part finish with same pattern 10, two other geometries of part that therefore process are in full accord, thereby the final sealing property of product is improved greatly.
