Description
Technical field
The invention belongs to Workpiece clamping device fields.
Background technique
When drilling gear end face at present, coupling gear fixed tooth shape is mostly used, fixture itself can not be detected, it can only
According to being adjusted again to fixture after the product actual measurement processed, fixed again using welding manner by gear is positioned after adjusting,
Fixture after welding is because the reason of internal stress, causes to deform, and fixture use process is very unstable, and the debugging clamper time is long, product matter
Measure unstable, qualification rate is lower.
Authorization Notice No. is the patent document of CN102275080B, discloses a kind of device, including pedestal and is mounted on
Fixture combination on the pedestal, the fixture combination include fulcrum bearing, locating piece, resilient sleeve, pull rod, positioning pin, briquetting with
And location key seat, the upper horizontal of the fulcrum bearing are shelved with gear, the locating piece is stuck in the keyway of the gear, described
The spherical head of positioning pin is horizontally inserted between two teeth of the gear to prevent gear from rotating, and the upper end of the resilient sleeve is through
In the inner hole of the gear, the pull rod passes through resilient sleeve from the top down and the tapered tail of pull rod struts the upper end of resilient sleeve
To realize the zero-clearance positioning of gear and resilient sleeve, the lower end of the pull rod is protruded into the pedestal, and the briquetting is pressed in the tooth
The top of wheel.The fixture use process of technical solution welding is very unstable, and the debugging clamper time is long, unstable product quality,
Qualification rate is lower.And since the technical solution fixes gear using the method that pull rod deforms resilient sleeve, in the middle part of pull rod with
There is gap between resilient sleeve, in pull rod insertion, if the active force to resilient sleeve is excessive, part where the above-mentioned gap of resilient sleeve
It can be bonded with pull rod, cause resilient sleeve to disperse the lateral pressure of inner ring gear, fixed effect is not achieved.
Summary of the invention
The purpose of the present invention is to provide a kind of spiral gear position limiting devices to solve fixed tooth of the existing technology
When wheel, fixing element group to inner ring gear lateral pressure disperse the problem of.
In order to achieve the above object, base case of the invention provides a kind of spiral gear position limiting device, spiral tooth
Limiting device is taken turns, including pedestal and the fixture combination being mounted on the base, the fixture combination includes fulcrum bearing, fixation
Element group, locating piece, briquetting, the locating piece are stuck in the keyway of the gear, and the fixing element group includes pin, spiral
Item, spiral bar one end are fixed on pin, and pin is located at fulcrum bearing center, and the spiral bar other end is fixed in fulcrum bearing, spiral
Item extends from the bottom to top along pin periphery, and spiral bar even width, the center line of spiral bar is overlapped with the center line of pin, spiral shell
It is rounded to revolve the projection of item vertically.
The principle of this base case is: after gear is packed into fixing element, briquetting being swung on gear plane for gear
It compresses, positioning block header is placed in gear keyway.Then gib head portion is rotated, so that the spiral bar on pin is scattered, because of spiral shell
The spiral feature for revolving item is in round when spiral bar is scattered.Because spiral bar both ends are all fixed, when scattering, spiral bar circle number subtracts
It is few, and diameter becomes larger, and forms lateral pressure to gear hole inner wall.Because spiral bar extends from the bottom to top along pin periphery,
When scattering, spiral bar is scattered with pin center line.Because of spiral bar even width, in the center line and pin of spiral bar
Heart line is overlapped, and the projection of spiral bar vertically is rounded, so spiral bar is still rounded after scattering.Gear center hole
Also round, so can be bonded completely on the outside of spiral bar with gear hole inner wall after scattering, fix gear using frictional force.Cause
To be bonded completely on the outside of spiral bar with gear hole inner wall, make gear hole inner wall uniform force.
The beneficial effect of this base case is: when solving fixed gear of the existing technology, fixing element group pair
The problem of inner ring gear lateral pressure is dispersed.
Further, totally six groups of fixture combination on the base are set, are distributed according to the matrix of 2*3.Six stations are determined
Position design, improves work efficiency, reduces production cost.
Further, totally two pieces of the briquetting in the fixture combination, are pressed respectively against the left and right sides of the gear.Guaranteeing tooth
While taking turns stress balance, production cost further reduced.
Further, the pedestal is made of upper plate, lower plate and the backing plate being arranged between upper and lower bottom plate, described
Upper plate and lower plate are connected by screw to together, and lower plate is equipped with the T-bolt for connecting machine tool.It advanced optimizes
Understructure makes it easy to be fixed on lathe.
It further, is in gear-like at the top of the pin, the briquetting is equipped with the rotation stop gear matched with pin top,
Rotation stop gear is fixed by screws on briquetting.Complete gear it is fixed after, rotation stop gear is engaged with pin top, is then tightened
Screw prevents rotation stop gear from rotating, and then is able to rotate pin not, achievees the effect that keep gear stationary state.
Further, the fulcrum bearing is threadedly secured on pedestal.Replace fulcrum bearing can according to gear size.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the spiral gear position limiting device of the embodiment of the present invention；
Fig. 2 is the schematic diagram of fixing element group in the present invention.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail:
Appended drawing reference in Figure of description includes: T-bolt 1, briquetting 2, rotation stop gear 3, fixing element group 4, gear
