Description

A wheel detection device

technical field

The invention belongs to the technical field of train wheel production auxiliary equipment, and more specifically relates to a wheel detection device.

Background technique

With the intensification of competition in the train wheel market, the requirements for the quality of wheel products are becoming more and more stringent, not only requiring the internal quality of wheel products to meet the design specifications, but also having certain requirements for the appearance quality of wheels. Therefore, the finished truck wheels after billet cutting, billet heating, forging, heat treatment, rough finishing, hardness testing, super-detection, magnetic detection, and shot blasting all need to be inspected for appearance. At present, the appearance inspection of truck wheels is carried out on the grinding line. The grinding line is composed of a roller table and a turning machine. The turning machine is located in the middle of the roller table. Considering that the thickness of the hub of different wheels is different, the grinding line roller table is composed of two rows of rollers. , the inner or outer rim surface of the train wheel is supported on two rows of rollers, the distance between the two rows of rollers is constant, and the hub falls in the middle of the two rows of rollers. During the inspection, the small crane lifts the wheel to the roller table of the grinding line, the outer rim of the wheel faces down, the motor drives the roller to rotate, and transports the wheel to the inspection position, and the inspector inspects the inner rim of the wheel and other parts of the wheel that can be seen. After the inspection, inspection of the inner rim surface, etc., the rollers continue to run, and the wheels are sent to the tumbler, and the hydraulic rack cylinder of the tumbler is driven to start to move, driving the tumbler to turn over, thereby driving the wheels to turn over, and the turning is completed. The rollers run, driving the wheels to leave the turning machine and reach the roller table of the grinding line. At this time, the inner rim surface of the wheel is in contact with the roller table, and the rollers of the grinding line roller table rotate, and the wheel is sent to another inspection position to complete the outer rim of the wheel. Surface and other parts are inspected. After the inspection is completed, the small crane lifts the inspected finished wheels and puts them into stacks. The crane lifts the stacked wheels away from the grinding line. There are certain problems in this wheel appearance detection method. On the one hand, due to the certain width of the transport roller, the inspector needs to bend over when inspecting, which is extremely inconvenient. On the other hand, because the inspector inspects the wheel appearance, the wheel is in a static state. In order to complete the detection of the entire wheel surface, the inspector must rotate his body to a certain extent, and even needs to change positions frequently, which is prone to operational fatigue and increases labor intensity.

There is also a set between the bridge shaft and the tapered sleeve 5 There are plane bearings 10 connected, so that the movable connection between the bridge shaft and the tapered sleeve 5 can produce relative rotation, and at the same time, it does not require a large rotational force. At the same time, the axial force generated by the lifting cylinder 2 is determined by The bridge shaft is transmitted to the tapered sleeve 11. The detection device is in contact with the wheel 6 to be detected through the tapered sleeve 11. The tapered sleeve 11 is made of nylon to avoid scratching the wheel. The tapered sleeve 11 adopts a tapered structure, which is convenient for the wheel to be placed on the tapered sleeve to achieve reliable positioning. .

When the wheel detection device of the present invention works, the wheel 6 to be detected is transported directly above the wheel detection device through the grinding line roller table, the roller table stops running, and the lifting cylinder 2 of the detection device for wheel appearance detection gets the signal of the control switch and starts Rising, driving the upper support to move upward, the upper support drives the tapered sleeve to move upward through the bridge shaft, the tapered sleeve passes through the hub hole of the wheel to be tested, after the wheel is placed in place, the wheel is positioned against the wheel of the tapered sleeve On the portion 23, the positioning of the wheel to be detected is reliable like this. At this time, the lifting cylinder continues to drive the wheels to rise until the set height stops rising. The inspector starts to inspect the appearance of the wheel, and rotates the wheel rim by hand while inspecting, so that the inspector can complete the entire wheel appearance inspection in one position. After the inspection is over, the lifting cylinder starts to drive the tapered sleeve down until the wheel falls on the roller table of the grinding line, and the inspection work is completed.

In the wheel detection device of the present invention, by setting the lifting cylinder and the conical sleeve movably connected with the lifting cylinder, when the wheel to be detected needs to be detected, the wheel to be detected can be movably set on the conical sleeve, and the lifting cylinder The height of the conical sleeve can be adjusted according to the needs, so as to meet the requirements of different inspectors for the height of the chasing taper sleeve. When the inspector is inspecting the wheel, there is no need for the inspector to change the position frequently, and the wheel appearance inspection can be completed conveniently and quickly. , while reducing the labor intensity of inspectors and improving the efficiency of wheel appearance inspection. At the same time, the wheel detection device of the present invention has simple structure, low investment, and low operation and maintenance costs; the detection device is not only easy to disassemble and move, but also extremely simple to operate and reliable in operation.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various improvements are adopted in the method concept and technical solutions of the present invention, or the present invention is converted without improvement.
