Description
Technical field
The utility model relates to a kind of gear hobbing anchor clamps, and particularly a kind of gear hobbing anchor clamps that adopt expansion set to connect belong to the Gear Processing industry.
Background technology
Adding in the process of work gear,, often cause gear in process, to produce geometric eccentricity because the assemblage gap between gear hobbing mandrel and the part is wayward with endoporus centering.Geometric eccentricity is the one of the main reasons that causes gear drive error, therefore, how to reduce gear hobbing clamping position error in the Gear Processing process, improves the Gear Processing precision, reduces gear and produces geometric eccentricity, is one of difficulty of facing of Gear Processing industry.During gear industry plate-like gear gear hobbing at present, mainly adopt two kinds of matched in clearance gear hobbing mandrel and band steel ball sleeve interference fit gear hobbing mandrels.The gear hobbing mandrel of matched in clearance and processed gear fit clearance are less, and clamping is wasted time and energy; Though and band steel ball sleeve cooperation gear hobbing mandrel can be eliminated the gap between gear and the anchor clamps well, whole scuffings of endoporus and clamping are comparatively required great effort.Thus, cause working (machining) efficiency not high.
Summary of the invention
The utility model technology provides a kind of simple in structure at the deficiencies in the prior art, and the gear hobbing anchor clamps of convenient mounting and clamping are to improve the efficient of Gear Processing.
For this reason, the utility model adopts following technical scheme:
A kind of gear hobbing anchor clamps, comprise base, packing ring, pull bar and gear hobbing upper press cover, described gear hobbing upper press cover and base and described pull bar install and cooperate and lay respectively at the cog upper/lower terminal of installation site of pull bar, described packing ring center drilling and cavity with indent, this packing ring installs by its centre bore and is fixed on the base, it is characterized in that: the described pull bar installed position that cogs is coated with an elastic expansion sleeve, described base is tapered, have upper and lower two round platforms, it is one up big and down small round table-like that the top of described pull bar is.
Below described pull bar top, has an annular protrusion.
Described projection is the small stair shape.
Described elastic expansion sleeve circumferentially has the bipyramid elastic expansion sleeve of a plurality of openings for the edge.
Between the top and described gear hobbing upper press cover of lathe, be provided with elastomeric element.
Described elastomeric element is a butterfly spring.
On lathe is top, also be provided with jump ring.
On described drag link body, be provided with groove, on described base, have screw, be provided with the pull bar guide screw that when the gear hobbing clamp working-station, is in the described groove in the screw.
The utility model is owing to used elastic expansion sleeve, and utilize on the base double tapered of round platform and pull bar top round platform to move and strut elastic expansion sleeve, reach the purpose of swelling workpiece to be processed (gear), realized the location, no gap of anchor clamps and workpiece endoporus, centering precision is good; And, make that the dismounting of elastic expansion sleeve is very convenient owing on pull bar, be provided with the projection of annular.
Description of drawings
Fig. 1 is an assembling schematic diagram of the present utility model;
Fig. 2 is the profile under the utility model duty.
Wherein: 1 be base, 2 for the pull bar guide screw, 3 for packing ring, 4 for fillister head screw, 5 for elastic expansion sleeve, 6 for workpiece to be processed (gear), 7 for the gear hobbing upper press cover, 8 for jump ring, 9 for butterfly spring, 10 for top in the gear hobbing, 11 be groove for annular protrusion, 13 for pull bar, 12.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.Will be to part same as the prior art in the utility model with reference to prior art.
As Fig. 1, shown in Figure 2, gear hobbing anchor clamps of the present utility model, comprise base 1, packing ring 3, pull bar 11 and gear hobbing upper press cover 7, described gear hobbing upper press cover 7 and base 1 and described pull bar 11 install cooperate and lay respectively at pull bar 11 cog the installation site on, following two ends, described packing ring 3 center drillings and cavity with indent, this packing ring 3 is threaded onto on the base 1 by its centre bore, and it is fixing with fillister head screw 4, described base 1 is tapered, on having, following two round platforms, described pull bar 11 installed position that cogs is coated with the bipyramid elastic expansion sleeve 5 that a pair of edge circumferentially has a plurality of openings, it is one up big and down small round table-like that the top of pull bar 11 is, and the below at top has an annular small stair shape projection 12.Pull bar 11 bodies are provided with groove 13, have screw on described base, are provided with pull bar guide screw 2 in the screw.In the lathe gear hobbing top 10 and described gear hobbing upper press cover 7 between be provided with butterfly spring 9, in lathe gear hobbing top 10, also be provided with jump ring 8.
During use, by the assembling drawing each accessory is packed into, at this moment, elastic expansion sleeve 5 is in the state that loosens; During work, adorn two workpieces to be processed (gear) 6 earlier, start lathe pull bar hydraulic pressure, pull bar 1 moves down, and the relative motion of round platform and pull bar top round platform struts expansion set and clamping work pieces 6 on the base; After treating pull bar 11 tension workpiece, lathe gear hobbing top 10 descends, and until the centre bore that pushes up pull bar 11 tops, gear hobbing upper press cover 7 is under the effect of butterfly spring 9, and the auxiliary end face that compresses workpiece to be processed (gear) 6 once more is to strengthen the rigidity of anchor clamps.After machining, move in the lathe gear hobbing top 10, gear hobbing upper press cover 7 resets; Move on the pull bar 11, elastic expansion sleeve 5 is ejected by the annular small stair shape projection 12 on the pull bar 11 and reaches the purpose of unclamping workpiece.In entire work process, move in the groove 13 of pull bar guide screw 2 on pull bar 11 bodies, with the shaft orientation moving range of control pull bar 11.
Though the utility model illustrates and describes by the reference preferred embodiment; but; those skilled in the art should understand; can be not limited to the description of present embodiment; in the scope of claims; can do the various variation on form and the details, every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
