The present invention will be further described in detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to better understand the aspects of the present invention.
Referring to fig. 1 to 5, fig. 1 is a schematic structural diagram of a tire positioning detection mechanism provided by the present invention, fig. 2 is a top view of the tire positioning detection mechanism in fig. 1, fig. 3 is a front view of a tire that is skewed during transportation, fig. 4 is a top view of a tire that is skewed during transportation, and fig. 5 is a schematic diagram of a tire that is skewed during loading.
The tire positioning detection mechanism provided by the invention is used for positioning detection of the tire 3 detected on the tire dynamic balance testing machine. As shown in fig. 1 and 2, the tire positioning detection mechanism includes a lifting bracket 2 and a detection portion 5 located at an upper end surface of the lifting bracket 2. The tire 3 is conveyed to the lifting bracket 2 by a conveying device such as a roller, and the detecting unit 5 can detect the position where the tire 3 is placed, and further determine whether the tire 3 is skewed.
Specifically, the lifting bracket 2 is rectangular, and one side of the lifting bracket 2 is provided with a servo motor 1 for driving the lifting bracket to lift. The center of the lifting bracket 2 is provided with a through hole penetrating in the thickness direction, the tire 3 is required to be placed at a position coaxial with the through hole, and then the lower rim 6 is lifted up to be matched with the upper rim 4 to clamp the tire 3. The detecting portion 5 may specifically be a structure such as a strain gauge disposed in the middle of the upper end surface of the lifting bracket 2, and when the tire 3 is placed on the upper end surface of the lifting bracket 2, the strain gauge deforms, so as to determine the placement position of the tire 3, and determine whether the tire 3 is skewed by the placement position of the tire 3. Of course, the detecting portion 5 may also be an infrared detecting switch, which includes an emitter 51 and a receiver 52, where the emitter 51 and the receiver 52 are respectively disposed at two sides of the tire 3 in the conveying direction, and the infrared ray is blocked during the conveying process of the tire 3, so as to detect the position of the tire 3. Of course, if the position of the tire 3 is detected by an infrared detection switch or the like, both the transmitter 51 and the receiver 52 thereof need to be higher than the upper end face of the elevating bracket 2 and lower than the width of the tire 3.
In addition, the tire 3 needs to be placed at a position coaxial with the via hole, and the detecting portion 5 needs to detect whether or not both sides of the tire 3 are placed in place, and thus the detecting portion 5 needs to be distributed on both sides of the via hole axis. If no tire 3 is detected on one side, it is indicated that the tire 3 is placed askew.
In this embodiment, the tire positioning detection mechanism can detect whether the tire 3 is placed askew, if the tire 3 is askew, the tire 3 is centered, and if the tire 3 is not askew, the tire positioning detection mechanism directly performs the dynamic balance detection, thereby avoiding unnecessary centering operation, saving centering time and improving detection efficiency.
Alternatively, the tire 3 is normally conveyed onto the lifting carriage 2 in the same direction, and thus all the detecting portions 5 are disposed in the conveying direction of the tire 3, and as shown in fig. 2, the detecting portions 5 are specifically infrared detecting switches whose transmitters 51 and receivers 52 are disposed on both sides in parallel with the conveying direction, respectively.
Specifically, the number of the detection parts 5 is two, and the detection parts are symmetrically distributed on two sides of the center of the through hole. The distance between the two is smaller than the diameter of the tire 3, and the difference between the distance between the two detection parts 5 and the diameter of the tire 3 is not greater than the allowable deviation range of the alignment of the tire 3 and the via hole. Of course, the user can increase the density of the detecting section 5 as needed, thereby improving the detection accuracy.
The tire positioning detecting mechanism further includes a judging device connected to the detecting portion 5, the detecting signal of the detecting portion 5 is transmitted to the judging device, and the judging device judges whether the tire 3 is placed askew or not based on the detecting signal. Specifically, since the detecting portions 5 are symmetrically distributed on both sides of the center of the via hole, the first judging portion can judge according to the detection signals of the detecting portions 5 on both sides, and as shown in fig. 3 and 4, when the detecting portion 5 on one side does not detect the tire 3, it is indicated that the tire 3 is placed askew. The judging device may be a single chip microcomputer, a PLC controller, or the like, and the first judging portion may be a switching circuit or the like in the judging device.
In addition, in the process of detecting the dynamic balance of the tire, the lower rim 6 moves upward to support the tire 3, and when the tire 3 is supported, the tire 3 is easily skewed due to uneven mass distribution, and at this time, if the upper rim 4 and the lower rim 6 clamp the tire 3, the tire 3 is scratched or the rim is damaged. It is therefore necessary to detect whether the tyre 3 is askew or not before loading.
Specifically, as shown in fig. 5, if the tire 3 is skewed during the lifting, one side thereof will first leave the upper end surface of the lifting bracket 2, and the opposite side thereof will finally leave the upper end surface of the lifting bracket 2. The judging device further comprises a second judging part connected with the detecting part 5, wherein the second judging part receives detection signals of the detecting parts 5 on two sides of the through hole in the process that the lower rim 6 lifts up the tire 3 upwards, a separation time difference exists between the two detection signals, and when the separation time difference of the two detection signals is larger than a preset time difference, the second judging part judges that the tire 3 is askew in the clamping process. The second judgment part may refer to a clock circuit, a timer, or the like in the related art.
In the present embodiment, the judgment means is provided with a first judgment section for judging whether or not the tire 3 is skewed when placed on the lifting bracket 2, and a second judgment section for judging whether or not the tire 3 is skewed when the lower rim 6 is lifted. And then can in time adjust tire 3, avoid will adorn the card in-process with tire 3 fish tail.
In addition, there is a certain difference in diameter of the tire 3 for dynamic balance detection, so that a plurality of types of tires 3 are positioned. In one embodiment of the invention, the detection section 5 comprises at least two detection section groups, each for detecting a tire 3 of a different diameter. As shown in fig. 1 and 2, the tire positioning detecting mechanism has two detecting part groups, each detecting part group includes two detecting parts 5 distributed along the conveying direction of the tire 3, and the distances between the two detecting parts 5 and the center of the through hole are equal. Of course, the user may set three or four detection units 5 in one detection unit group as needed, which is not limited herein.
Further, the lifting bracket 2 can be further provided with a chute along the conveying direction of the tire 3, a sliding block is arranged in the chute, and the detection part 5 is connected with the sliding block and moves along the conveying direction of the tire 3 under the driving of the sliding block. Specifically, the upper end surfaces of the two sides of the lifting bracket 2 are provided with sliding grooves, the cross sections of the sliding grooves and the sliding blocks can be in a convex shape, and the sliding grooves and the sliding blocks are in clearance fit. The slider has the wiring hole that extends along length direction, and its up end has the mounting hole that is used for installing detection portion 5, and the mounting hole is linked together with the wiring hole, and detection portion 5 sets up in the mounting hole, and the transmission line of detection portion 5 sets up in the wiring hole. Of course, the tire positioning detecting mechanism may be provided with a set of detecting portions, and the detecting portions 5 may be moved to the corresponding positions before the tires 3 of different diameters are required to be detected.
In addition, some tire dynamic balance testing machines in the prior art are not provided with centering devices, and once the tire 3 is skewed, manual centering is needed, so that the tire positioning detection mechanism is also provided with an alarm device. Specifically, the alarm device is an alarm lamp or an alarm buzzer connected with the judging device. When the tire 3 is askew, the alarm device receives the alarm instruction sent by the judging device, and then gives an alarm to prompt an operator to center the tire 3. Of course, the alarm device may further include a first alarm portion and a second alarm portion connected to the first judgment portion and the second judgment portion, respectively, where when the tire 3 is skewed in different types, the first alarm portion and the second alarm portion may send out different types of alarm signals, so as to facilitate the corresponding centering operation by an operator.
In this embodiment, the tire positioning detecting mechanism is provided with a plurality of detecting portion groups, and tires 3 of different diameters are detected by different detecting portion groups, so that the versatility of the tire positioning detecting mechanism is improved. In addition, the tire positioning detection mechanism is further provided with a chute and a sliding block, the sliding block moves in the chute, the position of the detection part 5 can be adjusted, the detection part 5 can detect tires 3 with different diameters, and the universality of the tire positioning detection mechanism is further improved. In addition, the tire positioning detection mechanism is also provided with an alarm device, and if the tire dynamic balance testing machine is not provided with a centering device, the alarm device can prompt an operator to perform centering operation.
The invention also provides a tire positioning detection method, which comprises the following steps:
Acquiring detection data of the detection part 5, and determining state information of the tire 3 according to the detection data;
The detecting section 5 detects whether the tire 3 is placed on the lifting bracket 2 to generate detection data including a placement position of the tire 3 on the lifting bracket 2 and a detachment time of the tire 3 from an upper end surface of the lifting bracket 2. The judgment means judges the state of the tire 3 based on the detection data, and determines whether the tire 3 is skewed.
Optionally, if the state information includes a placement position, determining whether the tire 3 is skewed according to the state information includes:
judging whether the tire 3 is coaxial with the through hole on the lifting bracket 2 according to the placement position;
As described above, the detecting portions 5 are distributed on both sides of the via hole, and if the detecting portions 5 detect the tire 3, it is indicated that the tire 3 is placed on the lifting bracket 2. If the detection portions 5 on both sides of the via hole detect the presence of the tire 3, it is indicated that the tire 3 is coaxial with the via hole on the lifting bracket 2.
If not, the tire 3 is judged to be skewed.
If only one of the detection units 5 detects the presence of a tire 3, it is indicated that the tire 3 is not coaxial with the via hole in the lifting bracket 2, i.e., that the tire 3 is skewed.
Further, the tire 3 positioning detection mechanism can also detect whether the tire 3 is askew when leaving the upper end surface of the lifting bracket 2.
If the state information includes a detachment time of the tire 3 from the upper end surface of the lifting bracket 2, the state information of the tire 3 is determined based on the detection data, including:
Determining a first detachment time of the tire 3 from the upper end surface of the lifting bracket 2 on one side of the via hole and a second detachment time of the tire 3 from the upper end surface of the lifting bracket 2 on the other side of the via hole respectively when the lower rim lifts up the tire 3 according to the detection data;
calculating a disengagement time difference according to the first disengagement time and the second disengagement time;
when the detecting section 5 detects that the tire 3 has disappeared from the lifting bracket 2, the judging means can record the escape time of the tire 3. The two-side detachment times of the tire 3 are a first detachment time and a second detachment time, respectively. The first detachment time and the second detachment time often have a difference value, and the absolute value of the difference value is the detachment time difference.
Determining whether the tire 3 is skewed based on the status information includes:
comparing the disengagement time difference with the preset time difference, if the disengagement time difference is larger than the preset time difference, the tire 3 is askew, otherwise, the tire 3 is not askew.
If the deviation time difference is large, it means that one side of the tire 3 is separated from the upper end surface of the lifting bracket 2 and the other side of the tire 3 is separated from the upper end surface of the lifting bracket 2, and the judgment device judges that the tire 3 is skewed according to the deviation time difference.
It should be noted that in this specification relational terms such as first and second are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
