Description
Technical field
The utility model belongs to gear machining apparatus field, and in particular to a kind of gear claw.
Background technology
Gear and its gear product are the important foundation part of mechanized equipment, the primary drive of most complete set of machines
Part is all gear drive.With the high speed development of national economy, the whole industry year gross sales amount has broken through hundred billion yuan, forms enterprise
Industry is polynary and deposit, the industry structures of joint development.Wherein, leading enterprise, leading enterprise have turned into promotes trade management level, production
The important force of product technical quality level and Innovation Ability, is that China from gear manufacture big country is turned into gear
Manufacturing power is made that outstanding contributions.
The problem of current gear exists during manufacturing is that in process, gear can be fixed for gear
Then gear is polished or removing surface, because the model of gear is different, the axis hole size in gear is also had nothing in common with each other,
In order to which gear is fixed, it is often necessary to be equipped with the claw of different model, the demand to meet production, so meeting for gear
Cause the low of production efficiency.
The content of the invention
The purpose of this utility model is to provide a kind of gear claw, can meet consolidating for the different gear of shaft hole diameter model
Determine demand, be easy to that continuously different gears are fixed, improve production efficiency.
To reach above-mentioned purpose, base case of the present utility model is as follows：
Gear claw, including base, base are provided with the top of threaded rod, threaded rod and are installed with jacking block, positioned at jacking block
It is connected with the threaded rod of lower section on bearing plate, bearing plate and is hinged with some symmetrical claws, claw is located at same circumference,
The section of the claw is inverted right triangular shape, and hypotenuse and the jacking block of claw offset；The diameter of circumference where claw
Less than the specified minimum shaft hole diameter of gear.
The principle of this programme gear claw is：
Base, which is provided with threaded rod, threaded rod, is connected with bearing plate, and axis hole can be aligned on bearing plate by gear to be blocked
The position of pawl；Gear is moved along claw to bearing plate.When gear is moved to the axis hole edge and claw edge phase mutual connection of gear
When touching, now it can not be moved down in jaw surface, now gear is tentatively fixed.Then threadingly bar to
Lower rotation bearing plate, when bearing plate is moved down, can drive claw to have the trend moved down, now jacking block can claw contact
Inclined-plane can produce displacement, but due to the relative displacement of jacking block direction when straight up, so, claw can be withstood outwards by jacking block
Extension, i.e. claw can extend to the shaft hole inner wall of gear, and then be realized under the collective effect of jacking block and claw to gear
It is further fixed.In the course of work of the present apparatus, the distance between the position that symmetrical claw is hinged on top plate is small
In the specified minimum shaft hole diameter of gear so that can meet the gear of different model can be inserted in axis hole claw, all
Jacking block and claw can be promoted by rotating bearing plate after preliminary fix come common further fixing to gear.Enter
And the demand that the gear for meeting different model is fixed, it is easy to that continuously different gears are fixed, improves production efficiency.
Preferred scheme one：As the further optimization to base case, support bar is provided between base and threaded rod, is improved
The stability of device.
Preferred scheme two：As the further optimization to base case, the contact position of jacking block and claw is inclined-plane, is reduced
Friction, improves the service life of equipment.
Preferred scheme three：As the further optimization to base case, claw number is 3, and claw is on same circumference
Distribution is triangular in shape so that fixed effect is more preferable.
Preferred scheme four：As the further optimization to base case, the length of base is more than the length of the bearing plate,
The area of base make it that the overall stability of device is more preferable more than bearing plate.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model gear claw embodiment.
Embodiment
The utility model is described in further detail below by embodiment：
Reference in Figure of description includes：Base 1, support bar 2, threaded rod 3, bearing plate 4, jacking block 5, claw 6,
Gear 7.
Embodiment is substantially as shown in Figure 1：
The gear claw of the present embodiment, including base 1, base 1 are provided with threaded rod 3, are set between base 1 and threaded rod 3
There is support bar 2；The top of threaded rod 3 is connected with the threaded rod 3 of the lower section of jacking block 5 and held provided with jacking block 5 is installed with
3 equally distributed claws 6 are hinged with fishplate bar 4, bearing plate 4, the inverted right triangular shape in section that claw 6 is, claw 6
Hypotenuse offseted with jacking block 5, the contact position of jacking block 5 and claw 6 be provided with match with the hypotenuse of claw 6 and inclined-plane.The institute of claw 6
Diameter of a circle be less than gear 7 specified minimum shaft hole diameter.The length of base 1 is more than the length of the bearing plate 4.
The specific work process of the present embodiment gear claw is：
Base 1 is located at the bottom of device, and base 1 is provided with threaded rod 3, threaded rod 3 and is connected with bearing plate 4, makes
The axis hole of gear 7 can be directed at the position of the upper clipping claw 6 of bearing plate 4 by the used time；Gear 7 is moved along claw 6 to bearing plate 4.Work as tooth
, now can not be downward on the surface of claw 6 when the axis hole edge and the edge of claw 6 that wheel 7 is moved to gear 7 contact with each other
Mobile, now gear 7 is tentatively fixed.Then threadingly bar 3 rotates down bearing plate 4, when bearing plate 4 is moved down,
Claw 6 can be driven to have the trend moved down, the inclined-plane that now jacking block 5 is contacted with claw 6 can produce displacement, and due to jacking block 5
Relative direction with claw displacement when straight up, so, claw 6 can be withstood by jacking block 5 can be to external expansion, i.e. claw 6
The shaft hole inner wall extension of gear 7, and then realize under the collective effect of jacking block 5 and claw 6 the further fixation to gear 7.
In the course of work of the present apparatus, the circle diameter that claw 6 is formed on bearing plate 4 is less than the specified minimum axis hole of gear 7
Diameter so that can meet the gear 7 of different model can be inserted in axis hole claw 6, can pass through after preliminary fix
Bearing plate 4 is rotated to promote jacking block 5 and common further the fixing to gear 7 of claw 6.And then realization can meet different shaped
Number gear 7 fix demand, be easy to that continuously different gears 7 are fixed, raising production efficiency.Base 1 and threaded rod 3 it
Between be provided with support bar 2, improve device stability.The contact position of jacking block 5 and claw 6 be provided with match with the hypotenuse of claw 6 and
Inclined-plane, reduce friction, improve equipment service life.The length of base 1 is more than the length of the bearing plate 4, the face of base 1
Product make it that the overall stability of device is more preferable more than bearing plate 4.
Above-described is only that the known general knowledge such as concrete structure and characteristic is herein in embodiment of the present utility model, scheme
Excessive description is not made.It should be pointed out that for those skilled in the art, not departing from the premise of the utility model structure
Under, several modifications and improvements can also be made, these should also be considered as protection domain of the present utility model, and these are all without influence
