Description
Technical field
The utility model belongs to machine tool element technical field, and in particular to gear clamping mechanism.
Background technology
Gear drive is important one of machine driving form, and the accuracy of manufacture and intensity, wearability etc. directly affect machine
The operating of device and service life.It is therefore desirable to which precision is high, intensity is big, wearability is good.It is needed in process through at overheat
Reason, and it is heat-treated the deformation generated, by the coaxiality error and the flank of tooth of destruction original processing precision, especially pitch circle and centre bore
Distortion inaccuracy can bring totally unfavorable influence to gear drive.Therefore, after heat treatment, it must be positioned with pitch circle, be ground in inner circle
Inner hole grinding on bed, then the flank of tooth is cut with endoporus location mill, to ensure the concentricity of pitch circle and centre bore, and eliminate deformation of tooth surface.
In the prior art, the grinding of bore carries out usually on internal grinder.Equipped with special on grinding machine
Chuck, gear are positioned according to the pitch circle of gear by roller, ball, gear or rack in chuck.When gear is installed, positioning
Roller is all fixedly mounted using retainer, every time when processing, after gear is put into fixture, will be held retainer, will be rolled
Column is inserted into tooth socket and clamps again, and corresponding ball need to be required for being formed with ball with the pitch circle correspondence of gear, the radian of chuck jaw
Outer circle correspond to, therefore the material of each model will correspond to a set of cylinder and chuck jaw, if gear model is relatively more
Just need a large amount of corresponding cylinders and chuck jaw, and when using this method clamping gear, the time needed is very long, work effect
Rate is low.
Utility model content
The utility model aim is intended to provide a kind of gear clamping mechanism, using Principles of Gear Connection, can realize
Positioning and fixation to gear, and it is simple and quick, and positioning accuracy is high.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
Gear clamping mechanism, including chuck, the claw being set on chuck, the chuck include that at least three is uniformly distributed
Chuck panel, be used for the chuck base of connecting chuck panel, the chuck panel is sector, and chuck panel both sides are set
Have the first protrusion, the chuck panel and the chuck panel two-by-two between convexed to form by first for sliding claw first
Notch.
Claw is utilized by the way that the equally distributed chuck panel of at least three is arranged using the utility model of above-mentioned technical proposal
Complete 3 point locations.The technical program by improve claw structure, using the first notch complete claw on chuck panel into
It moves back.It when specific processing, is centered first by 2 claws and work gear to be added completion, after setting center, keeps 2 cards
Pawl is motionless, rotates clockwise 1 claw, by screw-thread fit, completes the locking of claw, then carries out the center of work gear to be added
It grinds in hole；It reloads after grinding processing, rotates 1 claw counterclockwise and the unlocked state of claw is completed by screw-thread fit, unlock
Afterwards, work gear to be added is replaced, then repeatedly lock step, the centre bore for carrying out work gear to be added are ground.
It further limiting, the claw includes the first transverse slat, the first axis pin, first gear, the first stud, the first sliding block,
First transverse slat top is arranged with the first circular hole for accommodating the first axis pin, and the setting of first axis pin one end is in the first circle
In hole, the first axis pin other end extends the first transverse slat surface, is cased with first gear outside the first transverse slat other end, institute
The first transverse slat lower part to be stated to be equipped with for the second through-hole across the first stud, second through-hole wall is equipped with the first round platform,
First stud includes integrally formed first stud nut portion and the first stud screw portion, the first stud nut
Partial diameter is more than the diameter of the first round platform, and the lock of claw is completed in the first stud screw portion and the cooperation of the first sliding block
It is fixed.
It should be noted that chuck base bottom is additionally provided with connecting seat, connecting seat side wall can extend 3 connecting plate difference
Cooperation claw is fixed, and connecting seat can be designed to arbitrary shape, it is only necessary to consider stationary jaw.
It further limits, the first stud screw portion outer wall is equipped with external screw thread, and first sliding block includes the first limit
Position block, the first connecting pole, first limited block connect the first connecting pole close to the first stud screw portion end, and described first connects
It connects column and is equipped with the first groove, first groove inner wall is equipped with and the matched internal thread of external screw thread.
It further limits, first limited block front and back end is arcwall face.
The centre bore grinding for carrying out work gear to be added will produce metal fillings, and long-term to process, it is convex that metal fillings can be attached to first
The surface risen, the first limited block designed using arcwall face, convenient for removing metal fillings.
Preferably, the chuck panel is 3, the chuck panel and the chuck panel two-by-two between pass through the first protrusion
Form 3 the first notches.
Preferably, the chuck panel is 6, the chuck panel and the chuck panel two-by-two between pass through the first protrusion
Form 6 the first notches.
Actually it is also to place 3 claws, only to facilitate in chuck it should be noted that using 6 chuck panels
It is molded on panel, processes complete perforative first notch, meanwhile, not used 3 the first notches can be as spare for use.Instead
For crossing, using 3 chuck panels, nonpenerative first notch is processed, has circular hole at chuck face plate center axis, is not easy to out
Mould.
It further limits, first gear is roller gear identical with processed module, pressure angle, helical angle.
The utility model compared with prior art, first, the first notch design on chuck not only facilitates the advance and retreat of claw to pacify
Dress, and can ensure being accurately positioned for claw, so that the precision for the work gear to be added being ground out reaches 0.001mm；
Second, using claw, clamping is carried out to gear to be processed, gear to be processed is determined using roller compared to existing
Position, the clamping time is shorter, can working efficiency be improved 3~5 times；
Third, in actual processing, the number of teeth of clamping gear is very few, will produce profile modified gear phenomenon, and it is existing that profile modified gear occurs
As rear, due to engaging not on pitch circle, additional center can be brought to adjust work.Selection first gear is roller gear, can
The clamping for meeting most of different size of gear, increases the use scope of clamping gear, avoids and often replaces clamping tooth
Wheel, improves work efficiency；
4th, after centralized positioning, keeps 2 claws motionless, pass through 1 claw cutting between locking and unlocking state
It changes, realizes quick-replaceable work gear to be added so that clamping is more accurate.
