Description
Technical field
The utility model relates to a kind of wide adjusting gear of section that is applied to tyre tester (as transient equilibrium, homogeneity/degree of eccentricity testing machine etc.), belongs to rubber manufacturing machinery and industrial automation field.
Background technology
In the technological process of making rubber tyre, need the online a series of test item that carries out, as before tire shipment, testing through transient equilibrium and homogeneity/degree of eccentricity, in making process, to carry out detection and the grading of relevant item at tire.
As on homogeneity/degree of eccentricity testing machine, it is the specialized equipment that carries out full-automatic online detection at all steel load tyre evenness, dimensional discrepancy and camber index.Usually needing to be detected tire is installed between the upper and lower wheel rim, the wheel rim axle docks and locks with following wheel rim axle on this moment, and then inflate, inflate reach test request pressure after, loading wheel loads detected tyre and carries out homogeneity, the every index measurement of degree of eccentricity.
The specification of tire has multiple, and the compact and advanced in performance testing machine of a nested structure should be able to detect the tire of different model, with versatility and utilization factor, the reduction equipment purchasing cost that improves testing machine equipment.
For the wheel rim of same specification, how to reach the purpose of testing different section width tire by the vertical distance of adjusting between the upper and lower wheel rim (being rim width), be more insoluble technical task always.
Existing tyre tester part-structure shown in the accompanying drawing 1 of back, the locking of main shaft part (20) and unclamp by air pressure and detect to realize, last wheel rim axial region (40) are inserted main shaft part (20) back and are cooperatively interacted and lock by locking groove (or screw thread) between fixture block (30) and the last wheel rim axial region (40).
In above-mentioned prior art scheme, last wheel rim (60) and following wheel rim (70) are realized the purpose that same wheel rim different section width tire is detected by changing groove (or screw thread) axial locking position between main shaft part (20) and the last wheel rim axial region (40).This structure bearing accuracy is relatively poor, and the machine error that causes thus directly has influence on measuring accuracy.
In view of this, the special present patent application that proposes.
The utility model content
The wide adjusting gear of tyre tester section described in the utility model, its purpose is to address the above problem and carries out the adjustment of different section width at the wheel rim of same specification, can solve the detection use of multiple model tire to realize the test battery machine.
Another purpose of design is, by described adjustment structure and the method for rim width up and down, realizes that online quick adjustment section is wide, adjusts accurately higher and be of value to and improve the debugging work efficiency.
For realizing above-mentioned purpose of design, the wide adjusting gear of described tyre tester section mainly includes:
Overcoat, axially sheathed along last wheel rim axle, overcoat are divided into the first that is connected by internal and external threads with last wheel rim axle and the second portion that is used for installing wheel rim;
Fork is located in first; Set up an office around axle, an end of fork connects a key that radially is set in first and last wheel rim axle, and the other end of fork connects an elastic deformation part;
Driver, its driver part and the coaxial setting of above-mentioned elastic deformation part are to change or to recover the deformation quantity of elastic deformation part when the original state;
Displacement transducer is used for perception and detects the described wheel rim of going up along last wheel rim axle axial moving direction and distance.
As above-mentioned basic scheme, before the wide adjustment of the section of carrying out, spacing between key formation overcoat (first) and the last wheel rim axle, namely both do not have relative displacement and rotation.
After upper and lower wheel rim shaft locking, when the wide adjustment of the section of carrying out, need earlier with above-mentioned key from the wheel rim axle extract out.
In fact, the elastic deformation part still has certain deformation quantity when original state, apply certain pressure with the key to the fork other end.Namely before the wide adjustment of section, key plays the spacing and positioning action between overcoat and the last wheel rim axle all the time, and no matter whether tyre tester is in detected state, and also no matter whether upper and lower wheel rim axle drives upper and lower wheel rim is done rotation at a high speed.
The effect of fork is, centered by its axle that is located in first was set up an office, the driver part by driver changed or recovers the deformation quantity of elastic deformation part when original state, with the radial position of operating key with respect to last wheel rim axle.Refer to along last wheel rim axle radially, the following content of this patent is identical herein.
In like manner, the following content of this patent indicated axially, be along last wheel rim axle axially.
The effect of displacement transducer is that perception detects upward wheel rim moving direction and distance vertically, to control the wide adjustment of section between the upper and lower wheel rim and to judge whether to adjust to the right place.
For improving the flexible and accuracy of lock-out state between control and change overcoat and the last wheel rim axle further, optimization at elastic deformation part and driver with the improvement structure is, described elastic deformation part is a spring, spring one end is installed on the counterbore of fork, and its other end is installed on the locating slot of first;
Described driver is a cylinder, and the output shaft of cylinder can insert counterbore with further compression or retracting spring.
For improving the adjustment levels of precision of the vertical distance of upper and lower wheel rim more, around the improvement of displacement transducer be,
Displacement transducer is assemblied in the support that is connected with mainframe; Be axially installed with the link of induction magnetic head along last wheel rim axle, be connected by bearing with overcoat.
When overcoat by the rotation of last wheel rim vertically in the moving process, drive link along vertical movement by bearing, this moment displacement transducer exactly perception detect moving direction and the distance of induction magnetic head, and then accurately calculate the last wheel rim that is connected in overcoat with respect to the vertical distance of wheel rim down, on the result with the finally wide adjustment of the section of being reflected in.
As mentioned above, the advantage that has of the wide adjusting gear of the utility model tyre tester section is:
1, can carry out the adjustment of different section width at the wheel rim of same specification, realize that the test battery machine adapts to the detection use of multiple model tire, the utilization factor of checkout equipment is higher, can reduce effectively and make and the detection cost.
2, realize that online adjusting section is wide, adjusting accurately, higher and debug process improves whole detection efficient than weak point.
