Description
Technical field:
The utility model relates to the tooling technical fields of the eccentric herringbone bear synchronism measurement on two-point press, especially
It is a kind of for measuring the tooling of eccentric herringbone bear synchronism on two-point press.
Background technique:
Eccentric herringbone bear is one of key component of mechanical press, in pressure machine cross-beam main transmission, eccentric people
Word gear and connecting rod, guide post, adjusting screw rod, sliding block constitute slider-crank mechanism.The rotary motion of eccentric herringbone bear converts
For the linear motion of slide body, to realize the punching press function of mechanical press.Therefore, the machining accuracy of eccentric herringbone bear is straight
Connect the kinematic accuracy for influencing sliding block and punching press stability.
Existing press machine generally mainly has an one point press and two-point press, in the main transmission of two-point press
Mainly by the eccentric herringbone bear in left and right, two groups of intermediate gears, connecting rod and single sliding block composition, two groups of crank mechanisms biographies of two-point press
Dynamic synchronism is to determine the principal element of the kinematic accuracy of press ram, if the synchronism of two eccentric herringbone bears is deposited
It will lead to slider tilt in difference, influence the stability of press machine, it is stuck to may result in sliding block when serious, in addition, due to
Therefore the asynchronous of two eccentric herringbone bears but will cause entire press machine vibration larger, to influence the service life of press machine.
Thus, it is necessary to measure eccentric the synchronizing property of herringbone bear after processing, existing synchronism measurement is such as special
Judge whether eccentric body is qualified disclosed by sharp CN103196344B by percentage meter reading, but CN103196344B institute is public
What is opened is the measurement and tooling to eccentric spur gear, is not particularly suited for eccentric herringbone bear, since there are spiral shells for eccentric herringbone bear
Swing angle, for herringbone bear because being influenced by helical angle, tooth socket is skewed slot in outer circle, and uses tooling disclosed in CN103196344B
When measuring, dial gauge thereon is not readily accessible to standard outer circle exterior feature, causes to measure, to cannot reach
Measure the purpose of synchronism.
So the application is the improvement made to the tooling of measurement synchronism.
Utility model content:
The utility model provides a kind of for measuring the tooling of eccentric herringbone bear synchronism on two-point press, its tool
There is synchronism measurement accurate, registration, qualification rate is high, reduces difficulty of processing, further improves the punching press essence of press machine
Degree, the advantages of improving stability, improve production efficiency, solves problems of the prior art.
Used technical solution is the utility model to solve above-mentioned technical problem
It is a kind of for measuring on two-point press the tooling of eccentric herringbone bear synchronism, including spindle seat, the mandrel
Seat bottom end is fixed with a hemisphere, and the spindle seat top is equipped with support rod, and it is fixed that the supporting bar top is rotatably connected to one
, it is connected in the fixing seat with one end of table bar, the other end is equipped with a dial gauge.The hemisphere passes through connection spiral shell thereon
Line is connect with spindle seat.
The support rod is threadedly coupled with spindle seat.
It is hinged between the support rod and fixing seat.
The utility model using the above structure, measurement can be synchronized to eccentric herringbone bear and measurement is accurate, is passed through
Spindle seat is set in the measurement tooling, and is overcome by spindle seat and the cooperation of the hemisphere of its bottom to eccentric herringbone bear
It is middle straight-tooth to be used to touch table mandrel and measure due to there are problems that for helical angle, while using hemisphere in herringbone bear
It is inlayed in slot wherein it is possible to the problem of rotating hemisphere in double helical tooth race, solving the problems, such as because of helical angle is immeasurable,
Meanwhile the precision and stability of slide block movement is improved, it avoids the stuck phenomenon of sliding block well further as synchronism, more subtracts
The small vibration of press machine, improves the service life of press machine.
Detailed description of the invention:
Fig. 1 is the main view of the utility model.
Fig. 2 is the left view of the utility model.
Fig. 3 is the main view for touching the straight-tooth that eccentric spur gear measures table mandrel.
Fig. 4 is the usage state diagram of application of the utility model on eccentric herringbone bear.
In figure, 1, spindle seat, 2, hemisphere, 3, connection screw thread, 4, support rod, 5, table bar, 6, fixing seat, 7, dial gauge,

Specific embodiment:
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in Figs 1-4, a kind of for measuring the tooling of eccentric herringbone bear synchronism on two-point press, including mandrel
Seat 1,1 bottom end of spindle seat are fixed with a hemisphere 2, and 1 top of spindle seat is equipped with support rod 4,4 top of support rod
It is rotatably connected to a fixing seat 6, is connected in the fixing seat 6 with one end of table bar 5, the other end is equipped with a dial gauge 7.By
1 bottom of spindle seat setting hemisphere 2 can overcome because hemisphere 2 can rotate in eccentric double helical tooth race due to eccentric herringbone
The helical angle bring of gear 8 measures the immeasurable problem of eccentric spur gear bring, registration, due to mentioning for synchronism
Height reduces the vibration of press machine, improves the service life of press machine.
Wherein, the diameter of hemisphere 2 is to be carried out calculating determination according to the modulus of eccentric herringbone bear 8.
The hemisphere 2 is connect by connection screw thread 3 thereon with spindle seat 1, is connected by dismountable connection screw thread 3
Connect easy to disassemble, hemispheroidal diameter needed for can going out according to the modulus calculation of each eccentric herringbone bear 8, connection screw thread
The hemisphere of the 3 suitable sizes of replacement easy to connect.
The support rod 4 is threadedly coupled with spindle seat 1.
Hinged between the support rod 4 and fixing seat 6, fixing seat 6 can rotate to adapt to different eccentric herringbones along support rod 4
The measurement request of gear 8.
The use process of the utility model are as follows:
When work, firstly, determining the size of hemisphere 2 by the modulus of eccentric herringbone bear 8, and pass through eccentric herringbone
The modulus calculation of gear 8 goes out to contact the position of A11 point and contact point B12.Hemisphere 2 is embedded in the tooth of eccentric herringbone bear 8
In slot, it is desirable that be bonded hemisphere 2 with two sides of tooth socket and not contact groove bottom, while it is inclined to require 2 diameter of hemisphere to be less than
The pitch diameter of heart herringbone bear 8 can guarantee that contact point is accurate in this way, while by the bottom face of spindle seat 1 and eccentric herringbone
The end face of gear 8 is tightly bonded, and is then measured using method disclosed in CN103196344B, checks whether standard closes
Lattice.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
