Description
Technical Field
The invention relates to the field of tire testing, in particular to a protective device for a tire dynamic balance testing station.
Background
As is well known, with the rapid development of the tire market, the competition of the tire is increasingly white, the tire production specifications are increased and flattened, the requirement on quality is more emphasized, the detection of dynamic balance data is more strict, the early spot inspection equipment in a laboratory is changed into the existing full inspection equipment, the data inspection and efficiency requirements on dynamic balance are greatly improved, and therefore, the defects of some dynamic balance inspection equipment are exposed, and continuous modification and improvement are needed. When a tire enters a detection station, particularly when the contact area between a narrow-end tire and a lifting conveyor belt is small, the adhesion friction force is small, when a conveyor belt bracket is at a lifting position, the tire is conveyed in three processes of acceleration, constant speed and deceleration, the narrow-end tire is easily positioned incorrectly under the action of inertia to cause deflection or falling off, after the bracket of the lifting conveyor belt descends, the tire is not properly placed on a lower rim but in a deflection state, when the upper rim descends, the tire is possibly pressed, and the upper rim is also likely to deflect to cause stress fracture of a suspension shaft to cause equipment accidents. There is also a case where the belt carriage is raised at the lowered position after the tire detection is completed, but the tire is not effectively held up, that is, the tire is deflected due to the tire sticking on the rim or the tire remover before the tire is held up, so that the tire is easily pinched or crushed or the dynamic balance of the couple sensor is damaged when the belt carriage is raised from the lowered position to the raised position.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a protective device for a tire dynamic balance testing station, which can prevent the phenomenon that a tire falls off in the process of transferring the tire in and out when the tire is detected in dynamic balance, so that the tire is extruded in the action process of a lifting platform, the working efficiency of equipment is influenced, and certain safety risk exists.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a protection device of tire dynamic balance test station, is equipped with the test rim, characterized by, and the left side and the right side of test rim are the vertical fixation respectively have a support, and the layer board is equipped with to support top horizontal installation, and the layer board top is equipped with the baffle, and the downside symmetry of baffle is fixed with four branches, four branches cartridge respectively in the spring upper end that corresponds, the lower extreme of spring is installed on the layer board, installs two distance sensor on the inboard layer board of spring relatively, distance sensor links to each other with programmable controller's signal input part.
The invention can also be realized by the following measures: the support is of a telescopic structure.
The invention has the advantages that the invention can effectively prevent the equipment from clamping the tire, breaking the upper rim suspension shaft due to the deflection of the tire or extruding the sensor by the stress of the main shaft, thereby saving the production cost and the equipment maintenance cost.

Detailed Description
In the figure 1, the invention is provided with a testing rim 2, a left bracket 5 is vertically fixed on the left side of the testing rim 2, the left bracket 5 is of a telescopic structure, the left bracket 5 can be locked by a locking nut after the height of the left bracket 5 is adjusted, the bracket can not be loosened, a left supporting plate 1 is horizontally arranged at the top end of the left bracket 5, a left baffle plate 6 is arranged above the left supporting plate 1, four support rods are symmetrically fixed on the lower side surface of the left baffle plate 6, the four supporting rods are respectively inserted at the upper ends of the corresponding left springs 7, the lower ends of the left springs 7 are installed on the left supporting plate 1, the left supporting plate 1 on the inner side of the left springs 7 is relatively provided with the first distance sensor 4 and the second distance sensor 3, the first distance sensor 4 and the second distance sensor 3 are connected with the signal input end of the programmable controller, and the positions of the first distance sensor 4 and the second distance sensor 3 can be adjusted in height and locked. Right branch frame 12 is fixed with a right branch frame 12 in the right side symmetry of test rim 2, and right branch frame 12 is for can stretching descending formula structure, and the not hard up phenomenon of support can not take place for right branch frame 12 height adjustment back available lock nut locking, and right branch frame 12 top horizontal installation has right layer board 13, and right layer board 13 top is equipped with right baffle 9, and the downside symmetry of right baffle 9 is fixed with four branches, four branches cartridge respectively in the right side spring 10 upper end that corresponds, the lower extreme of right side spring 10 is installed on right layer board 13, relatively installs third distance sensor 8 and fourth distance sensor 11 on the right layer board 13 of right side spring 10 inboard, third distance sensor 8 and fourth distance sensor 11 link to each other with programmable controller's signal input part, and third distance sensor 8 and fourth distance sensor 11's position height-adjustable and lockable.
The distance sensor of the invention is powered by a direct current 24V power supply and provides a trigger signal to a PLC module through an intermediate relay, the triggering condition of the distance sensor is that a baffle plate of an upper tire-dropping prevention device is within 6mm close to the distance sensor, the action direction of the baffle plate above the distance sensor is determined by 4 guide rods, 4 springs are added to ensure that the baffle plate returns to an initial position when no tire is pressed on, when the tire is transmitted to a detection station through a synchronous belt, a lifting platform descends, an upper rim ascends, the tire is stuck, the lifting platform ascends, and each step of the conveying belt conveying the tire to leave the detection station, the tire-dropping phenomenon that the tire deflects and the tire drops can possibly occur, when the phenomenon occurs, the tire-dropping prevention protection device can play a protection role, namely, when the tire touches the protection device, the distance sensor of the protection device can be triggered to generate a signal, the signal is sent to the PLC module, after the signal is processed, the dynamic balancing machine is automatically stopped and sends an alarm signal which comprises an acousto-optic alarm and alarm information displayed by a touch screen, and an operator immediately processes a dropped tire after finding the alarm signal and resets the machine to continue detection.
