Abstract
The utility model discloses a kind of gear grinding machines moulds, including mandrel and tensioner, mandrel includes cylinder, extending in the middle part of cylinder has fixed part, and the outer cylinder of fixed part is tapered surface, and tensioner is the annulus with opening, tensioner is set on the outer cylinder of fixed part, threaded hole is offered on the ring wall of tensioner, the slotted hole passed through for bolt is offered on fixed part, and bolt passes through fixed part and screws in the interior fixation completed to tensioner of threaded hole of tensioner.The utility model is compared with prior art, outer cylinder using tensioner in fixed part fixes change in location, to change the mated condition of the outer wall of tensioner and the inner hole of gear, gear is when fixed, as bolt screws in the increase of length in tensioner, tensioner gradually slides to the larger diameter end of fixed part outer cylinder, the outer diameter of tensioner just will increase, the outer wall of tensioner and the inner hole of gear are become being interference fitted from clearance fit, complete the fixation of gear, structure is simple, and fixed and quick.
Description
Technical field
The utility model relates to machinery fields, and in particular to a kind of gear grinding machines mould.
Background technique
Gear in process of production, needs for gear to be fixed on gear grinding machines, gear biggish for volume, from gear
External fixation be it is relatively difficult, often fixing tool is used to be fixed from the inner hole of gear, in order to guarantee gear fix tightly
Gu this mode mounts and dismounts all often by the outer cylinder of the inner hole of gear and fixing tool by the way of interference fit
Need to expend a large amount of manpower, production efficiency is low.
Summary of the invention
To solve the above-mentioned problems, the utility model gives a kind of gear grinding machines mould, has structure simple, can be quick
And it firmly completes to assemble with gear, while can also laborsaving and quick disassembly.
To achieve the goals above, the utility model uses following technical scheme: including mandrel and tensioner, mandrel includes
Cylinder, cylinder middle part, which is extended, fixed part, and the outer cylinder of fixed part is tapered surface, and the minimum diameter of the outer cylinder of fixed part is big
In the diameter of cylinder, tensioner is the annulus with opening, and the inner ring surface of tensioner is tapered surface, and tensioner is set in fixed part
Outer cylinder on, threaded hole is offered on the ring wall of tensioner, the extending direction of threaded hole and the axis direction of tensioner are consistent,
Offer the slotted hole passed through for bolt on fixed part, bolt passes through fixed part and screws in the threaded hole of tensioner and completes to rising
Fixed fixation.
It further, further include having fixture nut, with the smaller diameter end of fixed part for upper direction, mandrel is located on fixed part
Screw thread is provided on the outer wall of the cylinder of side, the lower end of fixed part is provided with cricoid fixed station, and the slotted hole is provided with solid
Determine on platform.
When the utility model is used, the outer wall of the inner hole of gear and tensioner is fixed by frictional force, with existing skill
Art compares, using tensioner fixed part outer cylinder fixed change in location, to change the outer wall and gear of tensioner
The mated condition of inner hole, for gear when fixed, as bolt screws in the increase of length in tensioner, tensioner gradually slides to fixation
The outer diameter of the larger diameter end of portion's outer cylinder, tensioner just will increase, and the outer wall of tensioner and the inner hole of gear are become by clearance fit
For interference fit, to complete the fixation of gear, structure is simple, and fixed and quick；When disassembly, bolt need to be only rotated
The inner hole of the outer wall of tensioner and gear can be become clearance fit from being interference fitted, gear can easy removal.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
1 mandrel, 2 fixture nuts, 3 gears, 4 tensioners, 5 fixed parts, 6 bolts.
Specific embodiment
The technical solution of the utility model is further elaborated below with reference to specific embodiment.
As shown in fig. 1, including mandrel 1 and tensioner 4, mandrel 1 include cylinder, and extending in the middle part of cylinder has fixation
Portion, the outer cylinder of fixed part 5 are taper, and the minimum diameter of fixed part 5 is greater than the diameter of cylinder, and the lower end of fixed part 5 is provided with
Cricoid fixed station, fixed station offer the bolt hole of oblong from top to bottom.
Tensioner 4 is the c-type annulus for being provided with opening, and tensioner 4 is pressed on the outer cylinder of fixed part 5, tensioner 4
Inner ring surface is back taper cylinder, matches with the outer cylinder of fixed part 5, top-down spiral shell is provided on the ring wall of tensioner 4
Pit.
The bolt hole that bolt 6 passes through fixed part 5 screws in the threaded hole of tensioner 4 fixation completed to tensioner 4, with
Bolt 6 screws in the increase of 4 length of tensioner, and the change that lower end is slided to by upper end occurs in the position of 5 outer cylinder of fixed part for tensioner 4
Change, to change the outer ring size of tensioner 4, and then the inner hole of the outer wall of tensioner 4 and gear 3 was become from clearance fit
It is full of cooperation, completes the preliminary fixation of gear.
For further fixed gear 3, it is also provided with fixture nut 2, is matched with fixture nut 2, outside mandrel 1
Screw thread is provided on cylinder, fixture nut 2 is set on mandrel, the lower end surface of fixture nut 2 and the upper end face contact of tensioner 4
Cooperation, prevents tensioner 4 from falling off.
When the present embodiment is in use, first gear 3 is set at fixed part 5, then assembles tensioner 4, rotation bolt 6 is straight
Until the inner hole of the outer wall of tensioner 4 and gear interference fit, then the rotation of fixture nut 2 is set to the upper end of tensioner 4 again,
Complete assembling.When disassembly, above-mentioned steps are executed in turn.
Unmentioned technology is the prior art in the utility model.
It it should be noted that the present embodiment is the optimum embodiment of technical solutions of the utility model, but is not to this reality
With further limiting for new technique scheme, any deterioration or equivalents should belong to the guarantor of the utility model claims
It protects within range.
