Abstract
The utility model discloses a hobbing fixture. The hobbing fixture is characterized by comprising a hobbing mandrel. One end of the hobbing mandrel is fixed on a machine tool. A hobbing locating piece is arranged at one end, fixed on the machine tool, of the hobbing mandrel, and a nut is arranged at the other end of the hobbing mandrel. A clamping locating sleeve is arranged in the middle of the hobbing mandrel. Matched expanding sleeves are arranged on outer walls at two ends of the clamping locating sleeve. A workpiece is sleeved on the expanding sleeves, the nut is tightly screwed to enable the expanding sleeves to squeeze outwards, so that the expanding sleeves are in interference fitting with the workpiece, the clamping locating sleeve is squeezed inwards, and the clamping locating sleeve is in interference fitting with the hobbing mandrel, and then the workpiece is machined. Due to the fact that the expanding sleeves are fixed at both ends of the clamping locating sleeve, two workpieces can be fixed, so that the two workpieces can be machined at the same time, working efficiency is improved, and the structure is convenient to dismount and mount.
Description
Technical field
The utility model relates to a kind of gear hobbing processing tool, and concrete is a kind of gear hobbing anchor clamps.
Background technology
Gear hobbing is the basic operation of Gear Processing, generally adopts Digit Control Machine Tool to add work gear at present, effectively raises machining accuracy and the working (machining) efficiency of gear, but present numerical control gear clamp structure complexity.The required precision height involves great expense, and loading and unloading are inconvenient, and once can only process a workpiece, and working (machining) efficiency is not high, is unfavorable for quick production.Therefore to design the demand that a kind of novel gear anchor clamps satisfy the user.
The utility model content
The utility model proposes a kind of gear hobbing anchor clamps, the working (machining) efficiency of raising is conducive to quick production.
The technical solution of the utility model is achieved in that a kind of gear hobbing anchor clamps, comprise the gear hobbing mandrel, described gear hobbing mandrel one end is fixed on the lathe, a described gear hobbing mandrel fixedly end of lathe is provided with the gear hobbing keeper, the other end is provided with nut, gear hobbing mandrel middle part is provided with the clamping and positioning cover, and clamping and positioning cover two ends outer wall is respectively equipped with the expansion set that is complementary.
Further, also be provided with packing ring between described nut and the expansion set.
Further, described clamping and positioning cover is the fusiformis structure of middle part radius greater than the two ends radius.
Further, described gear hobbing keeper is annular pallet, in the described annular pallet centre bore gear hobbing mandrel is set.
The beneficial effects of the utility model are: workpiece is enclosed within on the expansion set, by screwing nut, make expansion set outwards push, thereby be connected with the workpiece interference, inwardly push the clamping and positioning cover, make clamping and positioning cover be connected with the interference of gear hobbing mandrel, then workpiece is processed, owing to clamping and positioning is overlapped all fixing expansion sets of two ends, therefore can fix two workpiece simultaneously, thereby can process two workpiece simultaneously, improve operating efficiency, and also easy disassembly of this structure.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the use view of the utility model embodiment.
Among the figure: 1, gear hobbing mandrel; 2, gear hobbing keeper; 3, expansion set; 4, clamping and positioning cover; 5, nut; 6, packing ring; 7, spacer ring.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, a kind of gear hobbing anchor clamps shown in Figure 2, comprise gear hobbing mandrel 1, described gear hobbing mandrel 1 one ends are fixed on the lathe, described gear hobbing mandrel 1 a fixedly end of lathe runs through gear hobbing keeper 2, described gear hobbing keeper 2 is annular pallet, the other end is threaded with nut 5, and gear hobbing mandrel 1 middle part is provided with clamping and positioning cover 4, described clamping and positioning cover 4 is that the middle part radius is greater than the fusiformis structure of two ends radius, clamping and positioning is overlapped 4 two ends outer walls and is respectively equipped with the expansion set 3 that is complementary, also be provided with packing ring 6 between nut 5 and the expansion set 3, two workpiece are installed between described annular pallet and the nut 5, be provided with spacer ring 7 between two workpiece.Workpiece is enclosed within on the expansion set 3, by screwing nut 5, make expansion set 3 outwards push, thereby be connected with the workpiece interference, inwardly the extruding clamping and positioning overlaps 4, make clamping and positioning cover 4 be connected with 1 interference of gear hobbing mandrel, then workpiece is processed, owing to clamping and positioning is overlapped all fixing expansion sets 3 of 4 two ends, therefore can fix two workpiece simultaneously, thereby can process two workpiece simultaneously, improve operating efficiency, and also easy disassembly of this structure; And that packing ring 6 makes between nut 5 and the expansion set 3 is tightr, and spacer ring 7 can be adjusted according to the gear hobbing size, make gear hobbing can be fixed on the gear hobbing mandrel 1.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
