Description

Technical Field

[0001] The present application relates to the technical field of bearing detection equipment, and in particular to a bearing magnetization detection device. Background Art

[0002] At present, the application of ABS magnetic seal rings in automobile wheel hubs is becoming more and more extensive, and the performance requirements of magnetic seal rings are becoming higher and higher. Therefore, the research and development of magnetization detection technology for ABS magnetic seal rings has important practical significance. However, the existing ABS magnetic seal ring magnetization detection system has certain limitations.

[0003] First, the existing ABS magnetic seal ring magnetization and detection system can only magnetize and measure a specific type of magnetic product, and cannot meet the detection needs of bearings of different types and sizes. Due to the differences in bearing types, sizes and other factors, there is currently no universal detection equipment, which has brought many inconveniences to manufacturers and limited the scope of application of this technology.

[0004] Secondly, the measurement accuracy and stability of the existing ABS magnetic seal ring magnetization detection system need to be improved. In practical applications, it is necessary to accurately measure and analyze the surface magnetic flux distribution waveform of magnetic products and the magnetic field parameters of each pole to ensure the quality and performance of the products. However, in order to achieve rapid placement and removal of bearings, it is difficult to ensure the concentricity of the bearings during rotation, causing the bearings to shake during rotation, which affects the detection accuracy. Utility Model Content

[0005] In order to improve the detection accuracy and application scope while facilitating taking and placing, the present application provides a bearing magnetization detection device.

[0006] The present application provides a bearing magnetization detection device, which adopts the following technical solution:

[0007] A bearing magnetization detection device includes a drive shaft, a detection sensor, a rotating mounting plate detachably mounted on the drive shaft, a lifting cylinder for adjusting the height of the detection sensor, a sliding cylinder for driving the lifting cylinder to move horizontally above the rotating mounting plate, and a lower positioning bearing for contacting with the detection bearing for positioning, wherein a socket for inserting the detection bearing is provided above the rotating mounting plate, and an upper positioning bearing is provided on the outer side of the detection sensor.

[0008] By adopting the above technical solution, the detection bearing is installed on the rotating mounting plate in a plug-in manner, and the disassembly and assembly are very simple and convenient. The replaceable rotating mounting plate can be replaced according to detection bearings of different specifications. At the same time, the sliding cylinder and the lifting cylinder can adjust the position of the detection sensor, so as to adapt to detection bearings of various sizes. During detection, the lower positioning bearing and the upper positioning bearing are used to position the upper and lower ends of the detection bearing, avoiding shaking during rotation after the detection bearing is installed due to reasons such as tolerances, thereby improving the detection accuracy.

[0009] In one embodiment: the lower positioning bearing is installed on an adjusting block, a waist-shaped hole is provided on the adjusting block, and the adjusting block is installed on an installation rod through the waist-shaped hole.

[0010] By adopting the above technical solution, through the setting of the adjusting block, the position of the lower positioning bearing can be adjusted, so as to be applicable to various different detection bearings.

[0011] In one embodiment: an adjusting rod is installed on the piston rod of the lifting cylinder, a waist-shaped adjusting hole for installation is provided on the adjusting rod, and the detection sensor is installed at one end of the adjusting rod.

[0012] By adopting the above technical solution, the position of the detection sensor can be adjusted through the setting of the adjusting rod. In this way, on the one hand, after the detection sensor is controlled by the sliding cylinder to be above the detection bearing, if the position of the detection sensor is not accurate enough, it can be adjusted through the adjusting rod. On the other hand, when the extension length of the sliding cylinder is insufficient, the adjusting rod can be used to compensate for the sliding cylinder.

[0013] In one embodiment: an installation block is installed on the piston rod of the lifting cylinder, and a plurality of threaded holes for installing the adjusting rod are provided on the installation block.

[0014] By adopting the above technical solution, the adjusting rod can be installed at different heights of the installation block to compensate for the telescopic range of the lifting cylinder.

[0015] In one embodiment: a plurality of installation grooves for embedding the adjusting rod are provided on the installation block, and both ends of the installation groove penetrate through the installation block.

[0016] By adopting the above technical solution, when installing the adjusting rod, only need to snap it into the corresponding installation groove and then install it with a bolt, which can facilitate the installation and adjustment of the adjusting rod.

[0017] In one embodiment: at least two horizontal installation grooves and one vertical installation groove are provided on the installation block, and the installation block is rotatably installed on the piston rod of the lifting cylinder.

[0018] By adopting the above technical solution, the horizontal mounting grooves at different heights can replace and adjust the mounting height of the adjusting rod, while the vertical mounting groove can form a new height after rotating the mounting block. Thus, more mounting heights of the adjusting rod can be formed on the premise of setting the mounting grooves.

[0019] In one embodiment: a worm and worm gear structure is mounted on the piston rod of the lifting cylinder, and the mounting block is connected to the worm of the worm and worm gear structure.

[0020] By adopting the above technical solution, the rotation of the mounting block is realized through the worm and worm gear structure, without the need to disassemble and reinstall the mounting block, reducing the adjustment difficulty.

[0021] In one embodiment: the rotating mounting disk is mounted on the driving shaft through an axial bolt.

[0022] By adopting the above technical solution, the structure is simple and it is convenient to replace the rotating mounting disk. Description of the Drawings
