Description

Technical Field

[0001] The utility model relates to the field of automobile parts detection, in particular to a wheel hub quality detection device. Background Technique

[0002] The wheel hub is one of the most important safety parts of an automobile, bearing the pressure of the automobile and the load quality, being affected by the dynamic torque during vehicle starting and braking, and also bearing the irregular alternating forces generated by dynamic loads from different directions such as turning, bumpy roads, and road obstacles during vehicle driving. The quality and reliability of the wheel hub are directly related to the safety of the vehicle and the personnel and materials on the vehicle. Therefore, it must undergo strict tests before being put into use. Usually, the detection of the wheel hub includes: air tightness, impact resistance, flatness, dynamic balance, etc.

[0003] However, usually, the detection of the flatness of the wheel hub is carried out by moving and irradiating the outside of the wheel hub with infrared rays. It is easy to generate a height difference when controlling the movement of the infrared ray source. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a wheel hub quality detection device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: A wheel hub quality detection device includes a support frame. On one side above the support frame, an infrared ray emitter is provided. On the other side above the support frame, an infrared ray receiver is provided. On the upper surface of the support frame, a wheel hub installation mechanism is installed. The wheel hub installation mechanism includes: a wheel hub support plate, wheel hub bolts, and a transmission shaft. At the lower end of the transmission shaft, a rotating motor is installed inside the support frame. Outside the wheel hub installation mechanism, on the upper surface of the support frame, a wheel hub guard plate is installed. Above the wheel hub guard plate, a protective elbow pipe is provided. Directly below the protective elbow pipe, on the upper surface of the support frame, a reserved installation rod is installed. Installation threads are provided on the outer sides of the upper end of the reserved installation rod and the lower end of the protective elbow pipe.

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-5 shown, this embodiment provides a wheel hub quality detection device, including a support frame 1. An infrared emitter 3 is provided on one side above the support frame 1, and an infrared receiver 4 is provided on the other side above the support frame 1. A wheel hub installation mechanism 7 is installed on the upper surface of the support frame 1. The wheel hub installation mechanism 7 includes: a wheel hub support plate 701, a wheel hub bolt 702, and a transmission shaft 703. A movable bearing is installed inside the support frame 1 on the outer side of the transmission shaft 703. A rotating motor 704 is installed inside the support frame 1 at the lower end of the transmission shaft 703. The rotating motor 704 is fixedly connected to the transmission shaft 703. The provided wheel hub installation mechanism 7 as a whole is used to control the wheel hub to rotate self - sufficiently to cooperate with the detection and processing of the infrared light beam. A wheel hub guard plate 5 is installed on the upper surface of the support frame 1 on the outer side of the wheel hub installation mechanism 7. The wheel hub guard plate 5 is fixedly connected to the support frame 1. A protective elbow pipe 6 is provided above the wheel hub guard plate 5. A reserved installation rod 101 is installed on the upper surface of the support frame 1 directly below the protective elbow pipe 6. The diameter length of the protective elbow pipe 6 is the same as the diameter length of the reserved installation rod 101. Installation threads 103 are provided on the outer sides of the upper end of the reserved installation rod 101 and the lower end of the protective elbow pipe 6. A connecting nut 102 is provided on the outer side of the installation thread 103. Connecting the protective elbow pipe 6 and the reserved installation rod 101 through the connecting nut 102 can achieve the purpose of protecting the upper part of the support frame 1, and at the same time, it will not affect the detection of the wheel hub.

[0024] As Figures 2-5As shown in the figure, in this embodiment, an adjustment bracket 2 is installed on the side surface of the support frame 1. The adjustment bracket 2 is fixedly connected to the support frame 1. An adjustment chute 201 is provided inside the adjustment bracket 2 on the outer sides of the infrared emitter 3 and the infrared receiver 4. Support connecting rods 301 are installed on the lower surfaces of the infrared emitter 3 and the infrared receiver 4 on the inner side of the adjustment chute 201. The infrared emitter 3 and the infrared receiver 4 are both movably connected to the adjustment chute 201 through the support connecting rods 301. A support nut 302 is installed on the outer side of the support connecting rod 301. The support nut 302 can adjust the height position of the support connecting rod 301 inside the adjustment chute 201 as a whole, so as to adjust the vertical height of the infrared emitter 3 and the infrared receiver 4 to detect wheels with different heights.

[0025] The working principle of the present utility model is as follows: When performing detection, after placing the wheel to be tested as a whole above the wheel support plate 701, install the wheel bolts 702 at the reserved installation positions of the wheel and then fix the wheel and the wheel installation mechanism 7. Then, align the multiple protective elbows 6 as a whole above the reserved installation rod 101, and install the connecting nut 102 by meshing it with the installation thread 103 on the outer sides of the protective elbow 6 and the reserved installation rod 101. The wheel to be tested is protected by the provided wheel guard 5 to prevent the wheel from flying out centrifugally. When the wheel is installed, rotate the support nut 302 as a whole on the outer side of the support connecting rod 301 to control the overall height dimension of the infrared emitter 3 and the infrared receiver 4, so that the infrared light emitted by the infrared emitter 3 is just not blocked by the wheel. Thus, the infrared receiver 4 can receive the infrared light. At this time, start the rotation motor 704 to drive the transmission shaft 703 to rotate as a whole, and control the wheel installed on the outer side of the wheel installation mechanism 7 to rotate rapidly. When the surface of the wheel to be tested is uneven, the infrared receiver 4 will not receive the infrared light signal. At the same time, when controlling the rapid rotation of the wheel, it can also be used to detect the dynamic balance of the wheel.
