Description

Technical Field

[0001] The present invention relates to the technical field of wheel hub detection, and in particular to a device and method for rapidly detecting wheel hub defects by using X-rays. Background Art

[0002] The wheel hub is an important component that connects the brake drum, wheel disc and half-axle. As an important component of the car, the wheel hub plays an irreplaceable role in the driving of the car. During the production process of the wheel hub, whether there are defects inside the wheel hub plays a decisive role in the stability and safety of the wheel hub. However, internal defects cannot be found by the "naked eye", so the wheel hub needs to be inspected by testing equipment.

[0003] The existing wheel hub detection equipment cannot move after the wheel hub is transferred to the platform, and can only detect different parts of the wheel hub by rotating the rocker arm. It is not only inconvenient to use, but also the detection is not comprehensive enough. Therefore, by adopting light tubes and flat-plate mounted C-type upper swing plus wheel hub rotation detection, the wheel hub detection is made more comprehensive, convenient and labor-saving.

[0004] However, when the above-mentioned wheel hub detection equipment is in use, due to the structural defects of the wheel hub centering mechanism, the wheel hub clamping and rotating mechanism, and the wheel hub conveying mechanism, the angle of the C-shaped swing cannot be too large, otherwise it is easy to interfere with and collide with the conveying mechanism, especially for large wheel hubs. In addition, the wheel hub may get stuck and blocked during centering, clamping and rotating, and conveying, which may cause the equipment to stop frequently. Summary of the invention

[0005] The purpose of the present invention is to provide a device and method for quickly detecting wheel hub defects using X-rays, which solves the technical problem that when the existing wheel hub detection equipment is in use, due to the structural defects of the wheel hub centering mechanism, the wheel hub clamping and rotating mechanism, and the wheel hub conveying mechanism, the wheel hub is stuck and blocked during centering, clamping and rotating, and conveying, thereby causing the equipment to often stop.

[0006] To achieve the above-mentioned purpose, the present invention provides a device for quickly detecting wheel hub defects using X-rays, comprising a lead room, a wheel hub centering mechanism, a wheel hub clamping and rotating mechanism, a light tube movement mechanism, a flat plate movement mechanism and a wheel hub conveying mechanism, wherein the wheel hub centering mechanism, the wheel hub clamping and rotating mechanism, the light tube movement mechanism, the flat plate movement mechanism and the wheel hub conveying mechanism are all located in the lead room, the wheel hub centering mechanism is used to clamp the wheel hub for centering and identify the wheel hub model, the wheel hub clamping and rotating mechanism is used to clamp the wheel hub and drive the wheel hub to rotate, the light tube movement mechanism is used to emit X-rays to irradiate the wheel hub, the flat plate movement mechanism is used to receive X-rays and cooperate with the light tube movement mechanism to jointly realize the detection of the wheel hub, and the wheel hub conveying mechanism is used to convey the wheel hub out of the lead room.

[0007] Among them, a peripheral feeding conveying mechanism and a peripheral discharging conveying mechanism are respectively arranged on the left and right sides outside the lead room. The peripheral feeding conveying mechanism is used to convey the wheel hub into the lead room, and the peripheral discharging conveying mechanism is used to convey the wheel hub out after the inspection is completed.

[0008] Among them, the lead room is divided into three chambers, namely a feeding ear room, a detection room and a discharging ear room. The feeding ear room is close to the peripheral feeding conveying mechanism, and the discharging ear room is close to the peripheral discharging conveying mechanism.

[0009] Wherein, a lifting door is arranged on a side of the feeding ear room close to the peripheral feeding conveying mechanism and a side of the discharging ear room close to the peripheral discharging conveying mechanism.

[0010] Wherein, a feeding door and a discharging door are respectively arranged on one side of the detection room close to the feeding ear room and the discharging ear room.

[0011] The hub centering mechanism identifies the hub model through a top camera and a side grating.

[0012] The present invention also provides a method for quickly detecting hub defects using X-rays, comprising the following steps:

[0013] Placing the wheel hub on the peripheral feeding and conveying mechanism, and allowing the wheel hub to be conveyed on the peripheral feeding and conveying mechanism;

[0014] When the wheel hub reaches the edge position of the peripheral feeding and conveying mechanism, the lifting door of the feeding awning is opened, the wheel hub is conveyed into the feeding awning, and then the lifting door of the feeding awning is closed;

[0015] Identifying the model of the wheel hub in the feeding wing room, and after identification, opening the feeding door of the testing room to transport the wheel hub to the testing position in the testing room;

[0016] When the wheel hub reaches the detection position, the wheel hub is clamped and rotated, and at the same time, the wheel hub is detected by emitting and receiving X-rays;

[0017] After the test, the discharge door of the test chamber is opened to convey the wheel hub to the discharge awning, and then the lifting door of the discharge awning is opened to convey the wheel hub to the peripheral discharge conveying mechanism;

[0018] The wheel hub is conveyed out through the peripheral discharging conveying mechanism to complete the entire inspection work of the wheel hub.

[0019] The present invention provides an apparatus and method for rapidly detecting wheel hub defects by using X-rays. When the wheel hub is conveyed to the wheel hub centering mechanism, the wheel hub is clamped and centered by the wheel hub centering mechanism, and the wheel hub model is identified. After the wheel hub model is identified, the wheel hub is clamped and rotated by the wheel hub clamping mechanism, and the wheel hub is driven to rotate. After clamping, X-rays are emitted by the light tube motion mechanism to irradiate the wheel hub, and then the X-rays are received by the flat plate motion mechanism, and the wheel hub is detected in cooperation with the light tube motion mechanism. After the wheel hub is detected, the wheel hub is conveyed to the outside of the lead room by the wheel hub conveying mechanism. The coordinated use of the wheel hub centering mechanism, the wheel hub clamping and rotating mechanism, the light tube motion mechanism, the flat plate motion mechanism and the wheel hub conveying mechanism avoids the phenomenon of frequent equipment shutdown caused by the jamming and obstruction of the wheel hub during centering, clamping and rotating, and conveying.

DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0029] First embodiment:

[0030] See also Figures 1 to 5 The present invention provides a device for quickly detecting wheel hub defects using X-rays, including a lead room 101, a wheel hub centering mechanism 102, a wheel hub clamping and rotating mechanism 103, a light tube moving mechanism 104, a flat plate moving mechanism 105 and a wheel hub conveying mechanism 106.

[0031] In this embodiment, when the wheel hub 112 is transported to the wheel hub centering mechanism 102, the wheel hub centering mechanism 102 clamps the wheel hub 112 for centering and identifies the model of the wheel hub 112. After identifying the model of the wheel hub 112, the wheel hub clamping and rotating mechanism 103 clamps the wheel hub 112 and drives the wheel hub 112 to rotate. After clamping, the light tube motion mechanism 104 emits X-rays to irradiate the wheel hub 112, and then the flat plate motion mechanism 105 receives the X-rays and cooperates with the light tube motion mechanism 104 to jointly detect the wheel hub 112. After the wheel hub 112 is detected, the wheel hub conveying mechanism 106 conveys the wheel hub 112 to the wheel hub 112. In addition to the lead room 101, the coordinated use of the hub centering mechanism 102, the hub clamping and rotating mechanism 103, the light tube movement mechanism 104, the flat plate movement mechanism 105 and the hub conveying mechanism 106 avoids the problem that the equipment often stops due to the jamming and obstruction of the hub 112 during centering, clamping and rotating, and conveying. This solves the technical problem that when the existing hub 112 detection equipment is in use, the hub 112 is jammed and obstructed during centering, clamping and rotating, and conveying due to the mechanism defects of the hub centering mechanism 102, the hub clamping and rotating mechanism 103, and the hub conveying mechanism 106, thereby causing the equipment to often stop.

[0032] Among them, the wheel hub centering mechanism 102, the wheel hub clamping and rotating mechanism 103, the light tube movement mechanism 104, the flat plate movement mechanism 105 and the wheel hub conveying mechanism 106 are all located in the lead room 101. The wheel hub centering mechanism 102 is used to clamp the wheel hub 112 for centering and identify the model of the wheel hub 112. The wheel hub clamping and rotating mechanism 103 is used to clamp the wheel hub 112 and drive the wheel hub 112 to rotate. The light tube movement mechanism 104 is used to emit X-rays to irradiate the wheel hub 112. The flat plate movement mechanism 105 is used to receive X-rays and cooperate with the light tube movement mechanism 104 to jointly realize the detection of the wheel hub 112. The wheel hub conveying mechanism 106 is used to convey the wheel hub 112 to the outside of the lead room 101.

[0033] Secondly, a peripheral feeding conveying mechanism 107 and a peripheral discharging conveying mechanism 108 are respectively arranged on the left and right sides outside the lead room 101. The peripheral feeding conveying mechanism 107 is used to convey the wheel hub 112 into the lead room 101, and the peripheral discharging conveying mechanism 108 is used to convey the wheel hub 112 out after the inspection is completed.

[0034] Again, the lead room 101 is divided into three chambers, namely a feed ear room 109 , a detection room 110 and a discharge ear room 111 . The feed ear room 109 is close to the peripheral feed conveying mechanism 107 , and the discharge ear room 111 is close to the peripheral discharge conveying mechanism 108 .

[0035] At the same time, a lifting door is provided on a side of the feeding ear room 109 close to the peripheral feeding conveying mechanism 107 and a side of the discharging ear room 111 close to the peripheral discharging conveying mechanism 108.

[0036] In addition, a feeding door and a discharging door are respectively provided on one side of the detection chamber 110 close to the feeding ear room 109 and the discharging ear room 111 .

[0037] Finally, the wheel hub centering mechanism 102 identifies the model of the wheel hub 112 through the top surface camera and the side grating.

[0038] When using a device of this embodiment that uses X-rays to quickly detect wheel hub defects, the wheel hub is placed in the middle of the line body to be an online device, and the manual loading and unloading is an offline device. When the device is an online device, the wheel hub 112 is placed on the peripheral feeding and conveying mechanism 107, and the wheel hub 112 is conveyed on the peripheral feeding and conveying mechanism 107. When the wheel hub 112 reaches the edge position of the peripheral feeding and conveying mechanism 107, the lifting door of the feeding ear room 109 is opened, and the wheel hub 112 is conveyed into the feeding ear room 109, and then the lifting door of the feeding ear room 109 is closed. The model of the wheel hub 112 is identified in the feeding ear room 109 by the wheel hub centering mechanism 102, and after identification, the feeding door of the detection chamber 110 is opened to convey the wheel hub 112 to the detection position in the detection chamber 110. When the wheel hub 112 reaches the detection position of the detection chamber 110, the wheel hub clamping and rotating mechanism 103 is used to clamp and rotate the wheel hub 112. At the same time, the light tube movement mechanism 104 is used to emit X-rays to irradiate the wheel hub 112, and then the flat plate movement mechanism 105 is used to receive X-rays. The flat plate movement mechanism 105 is used in conjunction with the light tube movement mechanism 104 to jointly realize the detection of the wheel hub 112. After the detection, the discharge door of the detection chamber 110 is opened, and the wheel hub 112 is transported to the discharge ear room 111. Then, the lifting door of the discharge ear room 111 is opened, and the wheel hub 112 is transported to the peripheral discharge conveying mechanism 108. Then, the wheel hub 112 is transported out through the peripheral discharge conveying mechanism 108 to complete the entire detection of the wheel hub 112.

[0039] To summarize, by using the hub centering mechanism 102, the hub clamping and rotating mechanism 103, the light tube movement mechanism 104, the flat plate movement mechanism 105 and the hub conveying mechanism 106 in coordination, the problem of frequent equipment shutdowns caused by jamming and obstruction during centering, clamping and rotating, and conveying of the hub 112 is avoided. This solves the technical problem that when the existing hub 112 detection equipment is in use, due to the mechanism defects of the hub centering mechanism 102, the hub clamping and rotating mechanism 103, and the hub conveying mechanism 106, the hub 112 is jammed and obstructed during centering, clamping and rotating, and conveying, causing the equipment to frequently shut down.
