Problems solved by technology
This method of press-fitting the seal of the hub bearing unit brings hidden dangers to the personal safety of the operators because of the manual placement of the seals; The sealing quality of the hub bearing unit cannot be guaranteed; moreover, the combination seal cannot be completely pressed in place due to the size tolerance of the seal itself by using this traditional press-fitting method; The size of the surplus will cause the combined seal to fall off, resulting in uncontrollable quality of the hub unit after the seal is pressed.

The invention discloses a press fitting and online checking machine for a sealing part of a full-automatic numerical control hub bearing unit. The press fitting and online checking machine comprises an air pressure adjusting valve, a pneumatic solenoid valve group, a fully-enclosed support cabinet, a total workbench, an industrial control computer, a man-machine conversation touch screen, a table for placing a sealing part to be pressed, and a table for placing a pressed sealing part, wherein sealing part press fitting and online monitoring positions, and pressed sealing part depth, parallelism and rotation torque checking positions are arranged on the workbench; the press fitting and online checking machine operates on each position through a mechanical material transporting claw and is integrated with an industrial computer technology, a numerical control system, a servo system, an air pressure system, a hydraulic system, an AD conversion technology, and an online measurement technology. The press fitting and online checking machine is high in measurement precision and can meet the technical requirements of the press fitting sealing part of the hub bearing unit in an automobile factory; besides reliability of the product quality can be effectively ensured, the productivity is improved, and the producing cost of the hub bearing unit is reduced.
Description
technical field [0001] The invention relates to a full-automatic numerical control wheel hub bearing testing machine, in particular to a full-automatic numerical control wheel hub bearing unit seal press-fitting and on-line testing machine. Background technique [0002] The hub bearing unit is an important safety component of the car. It not only drives the tires to rotate and drives the car to run, but also is an important part of the car to guide and support the weight of the car. When the car is driving in different road conditions, there are foreign objects such as dust, mud, rain, etc., in order to ensure that these foreign objects will not enter the interior of the wheel hub bearing unit, and also prevent the lubricating grease in the wheel hub bearing unit from leaking out, ensuring that the wheel hub bearing unit To work properly, the seal is one of the essential components of the hub bearing unit. In order to ensure the effectiveness of the work of the hub bearing ...
