Abstract
The utility model relates to a hobbing fixture, and belongs to the technical field of gear machining processes. The hobbing fixture comprises a mandrel, a centre seat, a draw bar and a centre sleeve, wherein a step hole is formed in the centre sleeve; a centre which is coaxial with the centre sleeve is arranged in the centre sleeve; a spring and a guiding sleeve are sleeved on the centre; one end of the spring is abutted to the step hole of the centre sleeve; the other end of the spring is abutted to the guiding sleeve; the centre seat is fixedly connected with the centre sleeve through a hexagon socket head cap screw; and the upper end of the centre corresponds to the end surface of the top of the draw bar. The hobbing fixture has the advantages that the hobbing fixture is simple in structure, low in cost and convenient to assemble and disassemble, and can be used on different gear hobbing machines.
Description
Technical field
The utility model relates to a kind of gear-hobbing clamp, belongs to Gearmaking Technology technical field.
Background technology
Gear hobbing is the basic operation of Gear Processing, adopts to roll to shave processes gear, and gear hobbing precision plays a decisive role to the final precision of gear, generally adopts at present Digit Control Machine Tool machining gears, effectively raises machining accuracy and the working (machining) efficiency of gear.But current numerical control gear-hobbing clamp all adopts and toply positions and feel relieved, its complex structure, involve great expense, handling are inconvenient; Meanwhile, existing fixture is all special fixture, when the gear of processing different size, all needs to process the fixture of different size, and the time of processing and replacing fixture is long, also causes the manufacturing expense of gear high, is unfavorable for that fast quick change produces.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model object be to provide a kind of simple in structure, cost is low, easy to loading and unloading, the gear-hobbing clamp that can use in different roller machines.
To achieve these goals, the utility model is by the following technical solutions:
The utility model provides a kind of gear-hobbing clamp, comprise mandrel, dead head and pull bar, also comprise in interior center sleeve with stepped hole, center sleeve, be provided with coaxial with it top, on top, be set with spring and fairlead, spring one end leans the stepped hole place at center sleeve, the other end leans fairlead, and dead head is fixedly connected with by hexagon socket cap head screw with center sleeve, and top upper end is corresponding with pull bar top end face.
Described center sleeve upper end is provided with end-tooth.
Described center sleeve is pyramid type boss.
Compared with prior art, the utlity model has following advantage:
1. it is simple in structure, and cost is low, easy to loading and unloading, can reduce the production cost of gear.
2. adopt center sleeve location and spring automatically to regulate centering, according to the length of processing parts, adjust the length of fairlead and the size of center sleeve, can produce the part of the different sizes of different length, thereby realize the versatility of gear-hobbing clamp.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: mandrel 1, dead head 2, hexagon socket cap head screw 21, center sleeve 3, fairlead 4, spring 5, top 6, workpiece 7, pull bar 8.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
As shown in Figure 1: the utility model provides a kind of gear-hobbing clamp, comprise mandrel 1, dead head 2 and pull bar 8, also comprise and in interior center sleeve 3 with stepped hole, center sleeve 3, be provided with coaxial with it top 6, on top 6, be set with spring 5 and fairlead 4, spring 5 one end lean the stepped hole place at center sleeve 3, the other end leans fairlead 4, and dead head 2 is fixedly connected with by hexagon socket cap head screw 21 with center sleeve 3, and top 6 upper end is corresponding with pull bar 8 top end faces.
Described center sleeve 3 upper ends are provided with end-tooth.
Described center sleeve 3 is pyramid type boss.
Installation process of the present utility model is as follows:
1, spring 5, fairlead 4 are sleeved on top 6 successively, then pack in center sleeve 3 top 6, the interior hexagonal round head screw 21 of center sleeve 3 use is fixed on dead head 2.
2, according to product type, on lathe base, fix special gear hobbing mandrel 1.
3, between center sleeve front end and pull bar 8, pack workpiece to be processed 7 into, top upper rolling tooth top 6, by auxiliary workpiece pressing 7 end faces of spring 5, the end-tooth of workpiece 7 end faces and center sleeve 3 upper ends is adjacent to, workpiece 7 another sides and pull bar end face are adjacent to, spring 5, according to the size of centre bore, regulates centering up and down automatically.Can, according to the size of processing parts and length, select the center sleeve of different size.
