Description
Technical field
The present invention relates to a kind of the be applied to fixed middle whirligig of tire x-ray examination machine and the improvement of method thereof, belong to rubber manufacturing machinery and industrial automation.
Background technology
For improving the quality of production and the safe handling cycle of automobile tyre, in manufacture process, need to carry out a series of online test items.As adopt X ray to carry out carrying out flaw detection to inner layer of tire, see through signal feedback that tire produces with imaging on receiving trap by ray, and then the performance deficiency such as whether checking inside tires does not plan a successor, bubble, steel wire fracture, and according to assay, tire is identified to classification.
Existing x-ray examination machine, normally will be detected tire vertically or accumbency be placed on pipeline, by driving X-ray tube to extend into inside, rim of the mouth and carry out ray capture.Start and carry out in process detecting, the normally tyre surface position from the detected tire of outside clamping by more than 2 groups arms, to realize the axis coinciding of tire and the centering device including above-mentioned arm parts, first carry out surely in operation.Then,, under the drive of one group of arm axial-rotation, tire rotates to coordinate the capture of X-ray tube in inside, rim of the mouth around its axle center.
As above-mentioned prior art feature, from tyre surface clamping is fixed, mainly exist following shortcoming with not enough with the structure and mode rotariling actuate:
1, tire tread has the decorative pattern of certain depth, when arm is clamping and driving the impact that is vulnerable to surface irregularity in the process of rotating, tire easily beats in the time of High Rotation Speed, unstable, thereby have influence on the picture quality of x-ray examination imaging, easily cause the decline of quality inspection;
2, clamp and rotarily actuate tire from tyre surface outside, the main region of x-ray examination as tyre surface, sidewall can be corresponding
Ground forms certain deformation, also directly can have influence on the picture quality of inspection imaging.
In view of this, the special present patent application that proposes.
Summary of the invention
Tire x-ray examination machine of the present invention and fixed middle spinning solution thereof, its object is to solve the problem of above-mentioned prior art existence and takes horizontal rotary tire, and also drive the mode of rotating in expanding outwardly calmly with driven roller from rim of the mouth, stability while improving tire High Rotation Speed to realize, and then improve x-ray examination image quality, improve the object of x-ray examination quality and efficiency.
Another goal of the invention is, by from inside to outside fixed with the structure and mode rotariling actuate, be verified the effect of regional deformation to reach remarkable reduction tire.
For achieving the above object, described tire x-ray examination machine mainly includes:
For the plumbous room of airtight detection tire and be arranged at plumbous room with lower device,
Conveying device, for being delivered into tire for plumbous room;
Roller platform, for providing unpowered swivel bearing in testing process to tire;
X-ray emitter, for to tyre rim internal emission X-ray with imaging;
X-ray receiving trap, for receiving the X-ray machine that penetrates tire with imaging;
Difference with the prior art part is, also comprises the fixed middle whirligig with following structure,
At least one drive roll, the rim of the mouth of pressing tire in testing process rotates with tire on the drive wheels; Drive roll is assemblied in the first travelling carriage, and the first drive unit that drives drive roll axial-rotation is installed on the first travelling carriage;

A side at the first travelling carriage or the second travelling carriage connects the second drive unit for driving it to reciprocatingly slide along guide rail.
As above-mentioned basic scheme, present patent application takes to stretch into from rim of the mouth main drive shaft and driven voller and then the nominal endocentric phrase expanding outwardly and mode.In the time driving detected tire rotation, main drive shaft and driven voller are pressed respectively the rim of the mouth of tire to realize the rotary mode that high speed is stable.
Be compared to tyre surface location and the prior art rotariling actuate, because the rim of the mouth place of tire does not have decorative pattern, in High Rotation Speed process, can maintain tire radially with axially on stability, there will not be play and swing significantly, therefore contribute to improve the quality of x-ray examination imaging and then correspondingly improve x-ray examination quality.
In addition, main drive shaft and driven voller are pressed respectively the rim of the mouth of tire, the material at rim of the mouth place material and tyre surface, position, sidewall can't form the transmission of direct soil fertility, therefore in rotariling actuate, can't cause the deformation at the position such as tyre surface, sidewall, that is to say the quality that can not have influence on x-ray examination imaging.Compared with this technology of locating and rotarily actuate from tyre surface outside with prior art, have and improve more significantly and improve.
For the accuracy that ensures further to position from tyre rim with synchronize consistance, can take following preferred version for above-mentioned mentioned gear train, be that gear train includes the first tooth bar that is installed on respectively the first travelling carriage and the second tooth bar that is installed on the second travelling carriage, the first tooth bar and the second tooth bar same gear that is connected with a joggle respectively.
For the first drive unit comparatively refinement with preferred scheme be, the first drive unit includes the motor that is installed on the first travelling carriage, is arranged with active rotation gear on motor output shaft, active rotation gear is meshed with the follower gear being sheathed on drive roll.
While driving detected tire High Rotation Speed for improving, there is enough friction force and effect at a stalemate, can on drive roll, be provided with for improving and protruding decorative pattern or the recessed decorative pattern of tyre rim skin-friction force.
Based on the architecture advances of foregoing invention design concept and tire x-ray examination machine, the present invention also can realize following fixed middle spinning solution simultaneously:
The position, sidewall of tire one side is flat on roller platform;
Before transmitting X-ray, the axis coinciding by tire with fixed middle whirligig;
Drive roll and driven voller are pressed respectively the bead of tire, and drive roll axial-rotation is with tire on the drive wheels axial rotation, and driven voller is auxiliary to lead.
Wherein, have in the refinement implementation step aspect driving transmission and the auxiliary guiding of rotation:
The first travelling carriage and the second travelling carriage, be slidably connected to guide rail by same gear train;
At drive roll, along radially the moving back and forth simultaneously of tire, driven voller keeps identical direction and displacement, and the bead of tire is synchronously pressed or discharged to drive roll and driven voller.
In addition, can on drive roll, be provided with protruding decorative pattern or the recessed decorative pattern friction force with raising and tyre rim surface.
As mentioned above, tire x-ray examination machine of the present invention and fixed middle spinning solution thereof have the following advantages:
1, the mode of tire driving rotation in taking to expand outwardly from rim of the mouth surely, the stability can effectively improve tire High Rotation Speed time, and then improve x-ray examination image quality.
2, the measuring means rotariling actuate based in from inside to outside determining and rim of the mouth place, can reduce significantly tire and be verified the deformation at region (tyre surface and position, sidewall), and then directly improve x-ray examination quality and efficiency.
