Description
Technical field
The utility model relates to the fixture of a kind of gear teeth portion location, belongs to mechanical part processing technique field.
Background technology
In Gear Processing process, often can run into gear teeth portion and other key element has the situation of strict status requirement as screw, pin-and-hole, keyway, mark etc.Conventional method mainly contains: the one, adopt the method for ruling, and the method acquired results ratio of precision is lower, and labour intensity is large, and efficiency is low, can not meet the requirement of production.The 2nd, in the situation that condition is filled perhaps, first process other key element, reprocessing tooth portion.The method is relatively higher than scribble method precision, but tooth portion adds relatively effort and time-consuming of adjustment in man-hour, adjusts intensity large, and efficiency is low.The 3rd, in the time that this gear pairing occurs, adopt tooth portion to process, then adopt the method for pairing to process other key element.But the method does not have relative interchangeability, therefore can not adapt to the requirement of mass production.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the fixture of a kind of gear teeth portion location is provided, and it is simple in structure, easy and simple to handle, quick, efficient, good reliability, can put forward gear teeth portion positioning precision greatly, meets the processing of gear high accuracy and mass production requirement.
The technical scheme providing according to the utility model: the fixture of gear teeth portion location, is characterized in that: comprise mandrel, base plate, push rod, the first lining, brute spring, liner clamp, the second lining, straight pin and driving lever; Described mandrel vertically arranges, and mandrel and base plate are connected and fixed; Described liner clamp is arranged on mandrel side, liner clamp is fixed on base plate, liner clamp is provided with cross through hole, and described push rod is assemblied in described cross through hole by the first lining, the second lining, and the first lining, the second lining are separately fixed at the inside and outside both sides of liner clamp; Described brute spring is contained in cross through hole, and second lining the inner is pressed on top, brute spring one end, and the brute spring other end pushes up the step bearing down on one on bar; Described push rod rear end is provided with arm-tie, and described arm-tie top is provided with mounting groove, and described driving lever is arranged in mounting groove by straight pin, driving lever can straight pin centered by 180 ° of free rotations.
As further improvement of the utility model, the shape of described push rod head is made as taper type.
Compared with prior art, advantage is the utility model: the utility model utilizes mandrel positioning workpieces bore, utilizes the tooth portion of push rod positioning workpieces gear, and positioning precision is high.The utility model utilizes brute spring and deflector rod structure, can facilitate the taking-up of workpiece gear and pack into, and brute spring makes the push rod tooth portion of positioning workpieces gear reliably simultaneously.The utility model is simple in structure, easy and simple to handle, quick, efficient, and good reliability can be put forward the positioning precision of gear teeth portion greatly, can meet the requirement of the processing of gear high accuracy and mass production.
Accompanying drawing explanation
Fig. 1 is structure and the applicable cases schematic diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the fixture of the gear teeth portion location in embodiment is mainly made up of mandrel 1, base plate 2, bolt 3, push rod 4, the first lining 5, brute spring 6, liner clamp 7, the second lining 8, straight pin 9, driving lever 10 and arm-tie 11 etc.
As shown in the figure, described mandrel 1 vertically arranges, and mandrel 1 is connected and fixed by bolt 3 with base plate 2; Described liner clamp 7 is arranged on mandrel 1 side, liner clamp 7 is fixed on base plate 2, liner clamp 7 is provided with cross through hole 12, and described push rod 4 is assemblied in described cross through hole 12 by the first lining 5, the second lining 8, and the first lining 5, the second lining 8 are separately fixed at the inside and outside both sides of liner clamp 7; Described brute spring 6 is contained in cross through hole 12, and second lining 8 the inners are pressed on brute spring 6 tops, one end, and brute spring 6 other ends push up the step bearing down on one on bar 4; Described push rod 4 rear ends are provided with arm-tie 11, and described arm-tie 11 tops are provided with mounting groove, and described driving lever 10 is arranged in mounting groove by straight pin 9, driving lever 10 can straight pin 9 centered by 180 ° of free rotations.
As shown in the figure, for push rod 4 can be located more accurately to workpiece gear 13, the shape of described push rod 4 heads is preferably made as taper type.
Operation principle of the present utility model is as follows:
In the time of needs positioning workpieces gear 13, pull push rod 4, stir driving lever 10 180 ° of rotations forward, unclamp push rod 4, make driving lever 10 withstand liner clamp 7 lateral surfaces, now push rod 4 retrudes, can not have influence on workpiece gear 13 and pack on mandrel 1.Then workpiece gear 13 is inserted on mandrel 1 with its endoporus centering, pull again push rod 4, stir oppositely 180 ° of rotations backward of driving lever 10, the push rod 4 that comes up, the moving workpiece gear 13 of dish gently simultaneously, makes push rod 4 heads head into workpiece, to being totally released, now, under the effect of brute spring 6, the tooth portion of the reliable positioning workpieces gear 13 of push rod 4 head, can carry out the processing with other key element behind gear teeth portion location.
In the time that needs take out workpiece gear 13, pull push rod 4, then stir driving lever 10 180 ° of rotations forward, unclamp push rod 4, now can conveniently take out workpiece gear 13.
