Specifically, when the metal hub 1 is not expanded and contracted and the blade mechanism can normally peel off the crystal on the surface of the metal hub 1, the distance D from the rim of the metal hub 1 to the blade mechanism is set as1At a distance D from the distance sensing unit 72When the metal hub 1 expands, the distance from the distance sensing unit 7 is reduced to D3，D2-D3Namely the expansion amount of the metal rotary hub 1, and the distance between the wheel rim of the metal rotary hub 1 and the blade mechanism is reduced to D1-(D2-D3) The blade mechanism is easy to rub the metal rotating hub 1 to generate scratches; in order to avoid the scratch of the blade mechanism and the metal rotating hub 1, the feeding/backing control mechanism 6 controls the backing D of the blade mechanism2-D3To maintain a constant real-time distance D between the blade mechanism and the rim of the metal hub 11(ii) a When the metal rotating hub 1 contracts, the blade mechanism is controlled to feed towards the metal rotating hub 1, so that the phenomenon that crystals on the surface of the metal rotating hub 1 cannot be normally stripped is avoided; the adjustment process when the metal hub 1 is contracted is similar to this. The distance between the blade mechanism and the metal rotating hub 1 can be adjusted in real time through the arrangement that the distance sensing unit 7 is matched with the feeding/returning control mechanism 6, and the adjusting precision is improved compared with the manual adjusting based on experience. Thereby maintaining the normal production of the equipment and prolonging the service life of the equipment.
The metal surface contactless gap adjusting device provided by the invention is described in more detail with reference to the accompanying drawings and specific embodiments.
In a specific embodiment provided by the present invention, since the production and stripping of the crystal are performed in a closed space, the peripheral portion of the metal hub 1 is usually provided with an equipment housing 2 for forming the closed space, in order to realize the distance fixing of the distance sensing unit 7 relative to the metal hub 1, a first fixing hole for installing the distance sensing unit 7 may be formed in the equipment housing 2, and the distance sensing unit 7 is fixed on the equipment housing 2 through the first fixing hole without destroying the sealing performance of the equipment housing 2; in addition, the equipment shell 2 is further provided with a second fixing hole for the blade mechanism to penetrate through so as to facilitate feeding/returning of the blade mechanism, the stripping tool 3 of the blade mechanism can feed to the metal rotating hub 1 through the second fixing hole to complete stripping of crystals, and the second fixing hole of the equipment shell 2 can be connected with the shell of the blade mechanism to form sealing of the second fixing hole.
In the above embodiment, the blade mechanism specifically includes the peeling tool 3, the peeling tool 3 is connected to the servo electric cylinder 4, the servo electric cylinder 4 is provided with the server 5, the server 5 is connected to the feeding/retracting control mechanism 6, when the distance sensing unit 7 detects that the distance between the distance sensing unit 7 and the metal hub 1 changes, that is, when the metal hub 1 expands with heat and contracts with cold, the distance sensing unit 7 transmits the change to the feeding/retracting control mechanism 6, and the feeding/retracting control mechanism 6 controls the servo electric cylinder 4 through the server 5 to drive the peeling tool 3 to feed or retract by the distance equal to the change, so as to maintain the distance between the peeling tool 3 and the rim surface of the metal hub 1 to be constant. The stripping tool 3 and the driving control mechanism thereof can refer to the prior art, the driving mechanism not only can adopt a servo 5 and a servo electric cylinder 4, but also can select a servo motor to match with a screw rod according to requirements, and the screw rod converts the rotary motion of the servo motor into the linear feeding/retracting motion of the stripping tool 3. The feed/retraction control mechanism 6 may employ a PLC or a control circuit board, and is not expanded in detail here.
The key point of the above embodiment is to detect the expansion amount or the contraction amount of the metal rotating hub 1, that is, the distance between the distance sensing unit 7 and the metal rotating hub 1, because crystals such as alkali pieces are attached to the surface of the metal rotating hub 1, the distance measured by ultrasonic ranging is substantially the distance between the crystals and the distance sensor 74, the thickness of the crystals changes with different production conditions, and the expansion and contraction changes of the metal rotating hub 1 cannot be accurately reflected, and the laser ranging has a certain error due to the light transmittance change of the crystals. In the embodiment provided by the present invention, the middle range sensor 74 of the range sensing unit 7 preferably employs an electromagnetic induction distance measuring sensor, and may also employ an eddy current distance measuring sensor as needed.
The distance measuring principle and structure of the electromagnetic induction distance measuring sensor and the eddy current distance measuring sensor can refer to the prior art, and no matter the electromagnetic induction distance measuring sensor or the current distance measuring sensor is adopted, the core is that the metal rotating hub 1 and the metal rotating hub 1 are made of different materials, and the corresponding distance sensor 74 can only detect the distance change between the identified metal rotating hub 1 and the surface crystal of the sensor, but cannot detect the surface crystal of the sensor.
Since the working environment of the distance sensing unit 7 is a high-temperature and high-corrosion environment, in order to avoid damage to the cable connected to the distance sensor 74 and the distance sensor 74, the distance sensing unit 7 is provided with a sealing housing 71, the sealing housing 71 may be rectangular and embedded in the first fixing hole, the distance sensor 74 is arranged at the end of the sealing housing 71, that is, the end close to the metal rotating hub 1 shown in the figure, the other end of the sealing housing 71 penetrates through the outside of the equipment housing 2, and the cable is connected to the sealing housing 71 and connected to the distance sensor 74 from the outside of the equipment housing 2.

Wherein, the heat dissipation air inlet pipe 72 extends to the bottom of the sealed housing 71, i.e. to the end away from the inductor 74, so as to provide better cooling effect.
The cooling medium can be cooling air, or liquid cooling according to actual needs, such as introducing cooling water into the heat dissipation air inlet pipe 72. When the distance sensor 74 and the sealing shell 71 are liquid-cooled, in order to avoid damage of the distance sensor 74 in a liquid environment, an sensor sealing shell 75 for sealing the distance sensor 74 is further provided at the periphery of the distance sensor 74, and the sensor sealing shell 75 and the sealing shell 71 can be made of high-temperature-resistant plastics or ceramics, so as to avoid affecting the distance between the distance sensor 74 and the metal hub 1.
Further, in order to improve the real-time of feed adjustment of the peeling tool 3, a distance sensing unit 7 is provided upstream of the blade mechanism with respect to the rotational direction of the metal hub 1. By upstream is meant that the metal hub 1 is rotated counterclockwise, the blade mechanism is disposed between the six o ' clock direction and the twelve o ' clock direction of the metal hub 1 when the distance sensor 74 is disposed at the twelve o ' clock direction of the metal hub 1; in other words, the angle between the distance sensor 74 and the blade mechanism is less than 180 ° and the blade mechanism is arranged behind the distance sensor 74, so that the feeding of the rear blade mechanism is adjusted in time after the distance sensor 74 detects the expansion and contraction of the metal hub 1.
It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.
