Description

Crank gear locating and machining frock
Technical field
It the utility model is related to a kind of Gear Processing frock, and in particular to a kind of crank gear locating and machining frock.
Background technology
Crank gear is more typical power transmission member in transmission mechanism, and the spindle nose of many crank gears sets for bias Meter, when the spindle nose to bias design is processed, it is necessary to enter the processes such as driving, milling, mill, so as to reach required size and essence Degree.Just need crank gear to be fixed positioning in process, and existing frock is difficult to eccentric spindle nose knot The crank gear of structure realizes stable stationary positioned, and certain difficulty is brought to accurate processing.
Utility model content
Deficiency of the prior art, the technical problems to be solved in the utility model are more than:A kind of crank tooth is provided Locating and machining frock is taken turns, for the stationary positioned of the crank gear of eccentric shaft head structure, is solved the above problems.
Crank gear locating and machining frock described in the utility model, including frock chassis, on frock chassis center It is fixed with centralized positioning sleeve, centralized positioning sleeve side is fixed with eccentric abutment sleeve, the centre-to-centre spacing between two sleeve axis Equal to the eccentric throw of crank gear spindle nose position;Circumferentially shape is provided with support post on frock chassis, if frock chassis is provided with Dry fixing hole.
In use, frock chassis is fixed on lathe, then crank gear is placed on the support post of frock, placed When, stationary positioned, processing are realized by centralized positioning sleeve and eccentric abutment sleeve.
Preferably, into a ladder, the excircle of crank gear is placed on support post upper surface for the upper surface of support post On, it is stepped to be easy to card to put fixation.
Preferably, centralized positioning sleeve and eccentric abutment sleeve are bolted on frock chassis, according to different songs The dimensional parameters of handle gear change the sleeve of correspondingly-sized.
Possessed beneficial effect is the utility model compared with prior art:
Crank gear locating and machining tool structure is simple, easy to use, the crank gear available for different shape size Eccentric spindle nose clamping position, improve processing efficiency and machining accuracy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of crank gear.
In figure:1st, support post;2nd, eccentric abutment sleeve;3rd, centralized positioning sleeve;4th, frock chassis;5th, eccentric spindle nose; 6th, centre bore.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings:
As shown in figure 1, crank gear locating and machining frock includes frock chassis 4, center is fixed with frock chassis 4 Centralized positioning sleeve 3, the side of centralized positioning sleeve 3 are fixed with eccentric abutment sleeve 2, and the centre-to-centre spacing between two sleeve axis is equal to The eccentric throw of crank gear spindle nose position;Circumferentially shape is provided with support post 1 on frock chassis 4, and frock chassis 4 is provided with some Fixing hole.
The upper surface of support post 1 is into a ladder.
Centralized positioning sleeve 3 and eccentric abutment sleeve 2 are bolted on frock chassis 4.
As depicted in figs. 1 and 2, in use, according to crank gear to be processed, the He of centralized positioning sleeve 3 corresponding to rotation Frock chassis 4 is fixed on the processing stations of lathe, then crank gear is put by eccentric abutment sleeve 2 on frock chassis 4 On the support post 1 of frock, during placement, centralized positioning sleeve 3 passes through the centre bore 6 of crank gear, the bias of crank gear Spindle nose 5 is inserted in eccentric abutment sleeve 2, you can is realized stationary positioned, is first processed the spindle nose of side, afterwards turn over processing opposite side Spindle nose.
